Description

The invention relates to a multi-part lid made of a paper material with a one-piece base body having a cover plate and an outgoing from the cover plate, encircling cover collar, wherein the cover collar in the patch on a container to be closed state extends away from the container upwards, and a reinforcing ring , which is connected by means of a peripheral frame with the cover collar. The invention also relates to a method for producing a multi-part lid from a paper material.

The invention is intended to provide an improved multi-part lid made of a paper material and an improved method for producing a multi-part lid from a paper material.

According to the invention for this purpose is a multi-part lid made of a paper material having a one-piece base body having a cover plate and a lid extending from the cover, circumferential cover collar, wherein the cover collar extends in an attached to a container to be closed state from the container upwards, and with a Reinforcing ring, which is connected by means of a peripheral frame with the cover collar is, provided, in which the reinforcing ring in a region below the cover plate, ie on a side opposite the cover collar side of the cover plate, a peripheral frame which forms a circumferentially circumferential shoulder on a radially inner side of the reinforcing ring, or circumferential in the circumferential direction Has bead.

With the invention, a multi-part lid is provided from a paper material, which is a simple structure and on the other hand can also be carried out stably. A peripheral frame forms a circumferentially circumferential shoulder, which can then be used to hook the lid to a mouth roll of a container to be closed. As a result, the lid sits securely on a container to be closed. As a frame, a portion of the reinforcing ring is called, which is folded over by 180 ° and then pressed. Advantageously, the peripheral frame is turned over below the cover plate by 180 ° and then comes to lie again on the material of the reinforcing ring. With this frame thus only a thickening of the reinforcing ring is achieved in its lower portion, but no two components are connected together. In contrast, with the peripheral frame of the reinforcing ring above the cover plate of the reinforcing ring is connected to the cover collar of the body. For this purpose, the reinforcing ring is also turned over at its upper end by 180 °, but the cover collar is then taken up between the two layers of material of the folded-over reinforcing ring. After pressing and optionally gluing or sealing the lid collar is then firmly connected to the reinforcing ring.

As an alternative to a peripheral frame below the cover plate, a circumferentially circumferential bead is provided on the reinforcing ring. Also, by means of a circumferential bead, a secure hold of the lid according to the invention can be achieved on a mouth roll of a container to be closed. The mouth roll of the container can, seen here in cross section, have a circular shape or, for example, an oval Shape when the mouth roll is pressed flat. Incidentally, the term "mouth roll" can be generally used for an upper, reinforced rim of a container, for example a plastic cup having an upper, thickened edge.

As paper material while paper and paper-like materials, eg. B. cardboard, cardboard or the like viewed, even one-sided or double-sided, coated with wax or plastic paper material. The coated side of the paper material may be heat sealable.

In a further development of the invention, the bead extends in the radial direction to the outside or inside.

In this way, a circumferential recess is created on the inside of the reinforcing ring, in which then the mouth roll of a container to be closed can be received to lock the lid on the container. The bead can be pressed flat, for example, and as a bead is also called a suitably shaped locking element.

In a further development of the invention, the peripheral frame above the cover plate is cylindrical.

The peripheral frame above the cover plate is an essential element of the multi-part lid according to the invention, since by means of the peripheral frame above the cover plate of the cover collar of the body is firmly connected to the reinforcing ring. The formation of this frame in a cylindrical shape facilitates their production, since the frame is easily accessible from both sides for a pressing tool. This applies both to annular frames and frames or covers of any basic shape, for example triangular or rectangular with advantageously rounded corners.

In a further development of the invention, an inner diameter of the reinforcing ring at the lower edge is larger than an outer diameter of the peripheral frame above the lid.

In this way, the reinforcing ring can be placed with its lower edge on the frame above the cover plate of another cover, so that a plurality of covers can be safely stacked.

In a further development of the invention, the reinforcing ring is widened radially outward in the region of its lower edge.

Due to the expansion above the expansion inevitably forms a paragraph, which can then be used as a stop when stacking a plurality of lids, to prevent multiple stacked lid too much slip on each other and thereby jammed. The widening is carried out, for example, in the form of an outgoing heel to then form a stop surface for the uppermost edge of the peripheral frame above the cover plate of the respective lower cup.

In a further development of the invention, the peripheral frame above the cover plate is frusto-conical and tapers in a direction away from the cover plate.

In this way, the stacking of several covers is facilitated, since the respective upper lid can easily be placed on the frusto-conically tapered peripheral frame of the respective lower lid.

In a further development of the invention, the reinforcing ring is frusto-conical in the region of its lower edge and widens in a direction away from the cover plate, wherein an inner diameter of the reinforcing ring at the lower edge is greater than an outer diameter of the peripheral frame at the upper edge.

In this way, the frustoconically widening lower portion of the reinforcing ring can be fitted in a simple manner on the frusto-conically tapered frame above the cover plate of the respective lower lid in a simple manner, so that a secure stacking is possible.

In a further development of the invention, the reinforcing ring is provided below the cover plate with a radially outwardly extending, circumferential bead, wherein an inner diameter of the reinforcing ring at the lower edge is greater than an outer diameter of the reinforcing ring immediately above the bead and smaller than a largest outer diameter in the range the bead.

In this way, the bead on the one hand forms a stop when stacking a plurality of lids and on the other hand can engage an inside of the outwardly extending bead when placed on a container to be closed on the mouth roll of the container, thereby ensuring a secure hold of the lid on the container ,

In the presentation of the Fig. 1 is a cover 10 with a base body 12 and a connected to the base 12 reinforcing ring 14 can be seen. The lid 10 is placed on a paper cup 16.

Like that FIGS. 2, 3 and 5 it can be seen, the one-piece base body 12 consists of a cover plate 18 and one on the periphery of the cover plate 18th The base body 12 thereby forms an upwardly, ie away from the cup 16 to be closed, open pot shape. The reinforcing ring 14 is placed around the circumference of the cover collar 20 and connected by means of a peripheral frame 22 with the cover collar 20. For this purpose, an upper edge of the cover collar 14 is turned over by 180 °, so that the cover collar 20 comes to rest within this envelope. The three superposed layers of material are then pressed together and optionally sealed or glued together to form the peripheral frame 22 then. The frame 22 has a circular cylindrical shape and is arranged at an angle of 90 ° to the cover plate 18. For pressing the frame 22, both sides of the frame 22 are thereby easily accessible for a punch or a similar pressing tool.

Below the cover plate 18 of the reinforcing ring 14 is initially also circular cylindrical and is then provided with a peripheral frame 26. The peripheral frame 26 at the lower edge of the reinforcing ring 14 is also formed by an envelope of the lower edge by 180 ° and subsequent pressing, however, the lower frame 26 is not used for connection with another component such as the upper frame 22. Rather, by the lower Frame 26 and especially the upper edge of the folded radially inward piece of material formed a circumferential shoulder, which is arranged at a constant distance from the cover plate 18. Between the cover plate 18 and the peripheral shoulder thereby a recess is formed, in which a mouth roll 28 of the cup 16 can be added in sections. When sliding the lid 10 of the paragraph at the upper inner edge of the lower frame 26 thereby snaps over the mouth roll 28 and thereby secures the lid 10 to the mouth roll 28 of the cup 16th

The lid 10 according to the Fig. 1 to 5 is structurally simple and inexpensive to manufacture. Both the top of the cover plate 18 and the circular cylindrical outer edge of the reinforcing ring 14 can be printed in a simple manner.

An underside of the cover plate 18, which in the fitted state faces the interior of the cup 16, is advantageously coated, for example with plastic or wax, in order to prevent penetration of moisture or liquid from the interior of the cup 16 into the paper material of the cover plate 18.

As a paper material according to the invention, a paper-like material is considered, for example, paper, cardboard, cardboard and the like. Also included in the term paper material is paper material coated on at least one side, for example plastic coated with plastic, in particular heat-sealable plastic.

Fig. 6 shows a cup 30 according to the invention according to another embodiment of the cup 16. The lid 30 is similar to the lid 10 of Fig. 1 constructed, so that only the different to the lid 10 features are explained below.

The cover 30 has a one-piece base body 32 and a reinforcing ring 34 placed around the circumference of the base body 32.

Like the sectional views of the Fig. 7 and the Fig. 8 can be seen, the base body 12 has a flat cover plate 18 and a lid plate 18 angled cover collar 20. The lid collar 20 encloses with the cover plate 18 at an angle of less than 90 °, so that the cover collar 20 has the shape of a tapered truncated cone. The reinforcing ring 14 is connected to the cover collar 20 by means of a peripheral frame 36, which is formed by an envelope of the upper edge of the reinforcing ring 34 by 180 ° and the inclusion of the cover collar 40 in the pocket formed thereby and subsequent compression. The upper frame 36 has the shape of a tapered truncated cone, wherein an outer diameter of the frame 26 decreases in a direction away from the cover plate 38.

In a region immediately below the cover plate 38 of the reinforcing ring 34 is then cylindrical, then to pass into a lower frame 38, which is also formed by an envelope by 180 ° of the lower edge of the reinforcing ring 34. By the lower frame 38 a paragraph is formed, which snaps in the attached state of the lid 30 under the mouth roll 28 of the cup 16, as already on the basis of Fig. 1 to 5 and was explained with reference to the lid 10. In contrast to the lid 10 of the Fig. 1 to 5 However, the lower frame 38 of the reinforcing ring 34 is formed frusto-conical, and a diameter of the lower frame 38 increases in a direction away from the cover plate 38.

Moreover, the inner diameter of the lower frame 38 is set to be slightly larger than or equal to the outer diameter of the upper frame 36, so that a plurality of the lids 30 can be stacked on each other, as in FIG FIGS. 9 and 10 can be seen. The lower frame 38 of a respective upper lid 30 is seated in the stacked state of several covers 30, see Fig. 10 , outside on the upper frame 36 of the respective lower lid 30. The frusto-conical design of both the lower frame 38 and the upper frame 36 prevent it that several stacked lid too much slip on each other and thereby jammed. The frusto-conical configuration of the lower frame 38 and the upper frame 36 makes it possible to stack many covers 30 without the resulting stack is unstable. Nevertheless, as has been stated, the lid 30 can be easily and reliably separated again.

The presentation of the Fig. 11 shows a lid 50 according to the invention according to another embodiment with a one-piece base body 52 and a reinforcing ring 54 on the circumference of the base body 52. The cover 50 is in Fig. 11 placed on the cup 16. The lid 50 is very similar to the lid 30 of the Fig. 6 to 10 constructed so that only the different components from the lid 30 components are explained.

Specifically, the main body 52, see FIGS. 12 and 13 , identical to the main body 32 of the lid 30 of Fig. 6 to 10 built up. The reinforcing ring 54 is initially formed circular cylindrical below the cover plate 58 of the base body 52, wherein this circular cylindrical portion extends to the region of the lower frame 58 on the reinforcing ring 54. The lower frame 58 is thereby angled in its course. Starting from the cover plate 58, the frame is thus initially circular-cylindrical in order then to expand frustoconically until the lowest edge of the frame 58 is reached, which simultaneously forms the lowermost edge of the lid 50.

As FIGS. 14 and 15 can be seen, a plurality of lids 50 stacked on each other, wherein the cover 50 in the same manner as the lid 30 of Fig. 6 to 10 are stackable.

The presentation of the Fig. 16 shows a lid 60 according to the invention according to another embodiment of the invention with a one-piece base body 62 and arranged on the circumference of the base body 62 reinforcing ring 64. The lid 60 is placed on the cup 16.

Like that FIGS. 17 and 18 can be seen, the base body 62 has a flat cover plate 68 and a perpendicular to the cover plate 68 angled cover collar 70. The lid collar 70 is connected by means of an upper peripheral frame 72 with the reinforcing ring 64. The formation of the upper frame 72 and thus the connection to the base 62 is identical to the lid 10 of Fig. 1 to 5 educated.

Below the cover plate 68 of the reinforcing ring 64 is then circular cylindrical and at the bottom of the reinforcing ring 64, a lower frame 76 is formed. The frame 76 has an expansion. Thus, the frame 76 extends in a direction away from the cover plate 68 away initially circular cylindrical, then increases its diameter in the shape of a truncated cone, and then to the bottom edge of the reinforcing ring 64th again circular cylindrical, but with a larger diameter than immediately following the cover plate 68 to run. The frame 76 thereby forms a paragraph, on the one hand facilitates the sliding of the lid 60 on the cup 16 and on the other hand ensures a very good stackability of multiple cover 60.

As Fig. 20 It can be seen, an inner diameter of the lower frame 76 in its lowermost, circular cylindrical portion, slightly larger than or equal to an outer diameter of the circular cylindrical upper frame 72. A lid can be pushed with the lower frame 76 thereby on the upper frame 72 of a lower lid, until the upper edge of the upper frame 72 abuts the shoulder which is formed by the frusto-conical widening in the course of the lower frame 76 of the upper lid 60. This paragraph on the inside of the lower frame 76 of the reinforcing ring 64 prevents characterized in that the respective upper cover 60 slips too far on the respective lower cover 60 and thereby jam the lid. Rather, the paragraph defines 78 in the course of the lower frame 76 of the reinforcing ring 64 a stop for the upper frame 72 of the respective lower lid when stacking a plurality of lid 60th

The presentation of the FIG. 21 shows a lid 80 according to the invention according to another embodiment of the invention with a one-piece base body 82 and a reinforcing ring 84 on the circumference of the base body 82. The lid 80 is mounted on a cup 16.

As in the representations of FIGS. 22 and 23 can be seen, the base 82 has a flat top plate 88 and a lid collar 88 bent from the lid collar 90. The lid collar 90 closes with the cover plate 88 at an angle of less than 90 degrees. The lid collar 90 is connected to the reinforcing ring 84 by means of a circumferential upper frame 92, which has a truncated cone shape tapering away from the cover plate 88.

Immediately below the cover plate 88, the reinforcing ring 84 has a circumferential, radially outwardly extending bead 86, which is formed in a circular section and the outer diameter of the mouth roll 28 of the cup 16 is adjusted. Below the bead 86 of the reinforcing ring 84 is then frusto-conical, with a diameter of the reinforcing ring 84 extends below the bead 86 in a direction away from the cover plate 88.

The lid 80 can thereby be easily pushed onto the mouth roll 28 and the reinforcing ring 84 expands by this Aufschiebevorgang until the mouth roll 28 snaps into the bead 86 and the lid 80 thereby fixed on the cup 16.

As based on the FIGS. 24 and 25 can be seen, the bead 86 serves with its upper side as a stop when stacking several covers 80. The bottom edge of the reinforcing ring 84 of an upper lid 80 is located on top of the bead 86 of the respective lower lid 80. The bead 86 prevents characterized in that the respective upper lid 80 slips too far on the respective lower lid 80 and the lid 80 thereby jammed in the stacked state.

The presentation of the FIG. 26 shows a lid 100 according to another embodiment of the invention with a one-piece main body 102 and a reinforcing ring 104 on the circumference of the base body 102. The lid 100 is placed on the cup 16.

The lid 100 is substantially identical to the lid 80 of FIGS. 21 to 25 constructed so that only the differences from the lid 80 are explained.

In contrast to the cover 80 of the reinforcing ring 104 is provided at its lower edge with a lower frame 106, which by turning the lower edge of the reinforcing ring 104 by 180 degrees and subsequent Pressing is formed. In a region below the radially outwardly extending bead 108 of the reinforcing ring 104 is frustoconical, even in the region of the lower frame 106. A diameter of the lower frame 106 expands in a direction of the base body 102 and its cover plate away. By the lower frame 106, an inwardly projecting paragraph is formed below the bead 108. When placing the lid 100 on the cup 16 therefore initially snaps the upper edge of the lower frame 106 behind the mouth roll 28 of the cup 16 and is thus already secured to the cup 16. If the lid 100 is then pressed further towards the cup, the mouth roll 28 snaps into the circumferential bead 108, thereby securing the lid 100 to the cup 16 in a particularly secure manner.

Based on the representations of FIG. 29 and FIG. 30 It can be seen that in the stacked state, a plurality of covers 100 each of the lowermost edge of the lower frame 106 of an upper lid 100 rests on the upper side of the bead 108 of a respective lower lid 100. This cooperation of the lower frame 106 of the respective upper lid and the bead 108 of the respective lower lid 100 thereby prevent the lid 100 from slipping too far when stacked and thereby jamming.

The representations of the FIGS. 31 to 35 show a lid 130 according to the invention, which is placed on the cup 16 and only slightly from that in the FIGS. 26 to 30 illustrated cover 100 differs.

The items of the lid 130 according to the invention are therefore not explained again, only to the differences from the lid 100 of FIGS. 26 to 30 is referred to.

Unlike the lid 100, see Fig. 30 , the radially outwardly extending bead 138 is slightly closer to the cover plate of the main body 132 of the cover 130 according to the invention. After the lid 130 is placed on the cup 16 and the mouth roll 28 of the cup is snapped from the inside into the bead 138, thereby lies on the outer edge of the cover plate of the main body 132 on top of the mouth roll 28.

In contrast to the lid 100 of the FIGS. 26 to 30 Moreover, the lower frame 136 of the lid 130 is formed slightly differently by the lower edge is indeed also folded over, but again extends so far up that he in the fitted state of the lid 130, see Fig. 33 , rests against the underside of the mouth roll 28. The undercut formed by the bead 138 is thereby increased and the lid 130 is particularly firmly seated on the cup 16th

Another difference between the covers 100 and 130 is that an upper frame 140 of the lid 130, where the main body 132 and the reinforcing ring 134 are connected to each other, has an outer diameter substantially to the inner diameter of the lower frame 136 of the reinforcing ring 134th equivalent. In the stacked state of several cups, see Fig. 35 , the inside of the lower frame 136 of each upper cup 130 thereby abuts on the outside of the upper frame 140 of the respective lower cup 130. A movement of the respective upper lid 130 when stacked toward the respective lower cup 130 is stopped by the abutment of the lower edge of the lower frame 136 of the respective upper cup 130 at the top of the bead 138 of the respective lower lid 130.

The representations of the FIGS. 36 to 40 show a further embodiment of a lid 150 according to the invention. The lid 150 is similar to the lid 50 of Fig. 11 to 15 constructed so that the items of the lid 150 will not be explained again, but rather only on the cover 50 of the Fig. 11 to 15 different features.

The lid 150 has, instead of an upper frame, a ring roller 160, which is formed on the upper edge of a reinforcing ring 154. The ring roll 160 describes in the sectional view of Fig. 38 starting from the outer edge of the reinforcing ring 154 an arc of 270 ° and lies with its end substantially parallel on a cover plate 158 of a base 152 of the lid 150. The cover plate 158 merges at its outer edge into a cover collar 162, which is bent away from the cup 16 by a little more than 90 ° and rests with its outer peripheral surface on an inner side of the reinforcing ring 154. The lid collar 162 is connected to the lid collar 154, for example glued or sealed. The end of the ring roller 160 may also be connected to the cover plate 158, but the end of the ring roller 160 may also lie only loosely on the cover plate 158.

The lower frame 158 of the reinforcing ring 154 does not differ from the lower frame 58 of the lid 50 of Fig. 11 to 15 ,

The representations of the FIGS. 41 to 45 show a further embodiment of a lid 170 according to the invention. The lid 170 is similar to the lid 50 of FIG Fig. 11 to 15 constructed so that the items of the lid 170 will not be explained again, but only to the cover 50 different components reference is made.

In contrast to the lid 50 of the Fig. 11 to 15 For example, the lid 170 has at its reinforcing ring 174 a radially inwardly extending flattened bead 180. This flattened bead 180 forms an inwardly projecting projection which is arranged so that between a bottom of a flat top plate 178 of the cup-shaped base body 172 and an upper surface of the bead 180 is a distance which substantially corresponds to the height of the mouth roll 28 of the cup 16 , When placing the lid 170 on the cup 16 of the first below the cover plate 178 lying portion of the reinforcing ring 174 is expanded radially outward until the flattened bead 180 snaps under the mouth roll 28 and then at the same time a bottom of the cover plate 178 on a Top of the mouth roll 28 is applied. The lid 170 is thereby fastened particularly securely to the mouth roll 28 of the cup 16.

An upper frame 176, with which the reinforcing ring 174 and the main body 172 are connected, is identical to the lid 50 of Fig. 11 to 15 educated. A lower frame 178 of the reinforcing ring 174 is formed by an envelope of 180 ° of the lower edge of the reinforcing ring 174 and widened in a cone shape to facilitate placement on the mouth roll 28 of the cup 16.

In the stacked state of several cups, see FIGS. 44 and 45 , sits a respective upper lid 170 with the underside of its flattened bead 180 on the upper edge of the frame 176 of the respective lower lid 170. When stacking a plurality of covers 170 is thereby prevented that the lid slip too far into each other and thereby wedged. An inner diameter of the lower frame 178 of the respective upper lid 170 abuts on an outer side of the upper frame 176 of the respective lower lid 170. As a result, several covers 170 are securely stacked in the stacked state.

The presentation of the FIG. 46 shows a lid 110 according to the invention according to a further embodiment of the invention in a view obliquely from below and the FIG. 47 shows the lid 110 in a view obliquely from above. With the exception of the rectangular basic shape of the lid 110, this is the same as the lid 100 of FIGS. 26 to 30 trained so that this structure will not be explained again. Several of the lids 110 are stackable and the corners of the rectangular basic shape are each rounded. This facilitates the formation of the upper peripheral frame, with which the main body and the reinforcing ring of the lid 110 are connected to each other. But above all, this rectangular basic shape with rounded corners is also feasible in a cup and especially in the formation of a mouth roll at the top of such a cup with a rectangular basic shape.

The presentation of the FIG. 48 shows a lid 120 according to another embodiment of the invention in a view obliquely from below and FIG. 49 shows the lid 120 in a view obliquely from above. With the exception of the triangular basic shape of the lid 120 is the Figures 48 and 49 same as the lid 110 of the FIGS. 46 and 47 and thus also the same as the lid 100 of the FIGS. 26 to 30 built up. Like these lids, several of the lids 120 are stackable. The corners of the triangular basic shape are rounded.

For producing a multi-part lid according to the invention from paper material, the main body is first formed from a one-piece paper material blank, wherein the main body receives a cup shape with a cover plate and a circumferential cover collar extending from the cover plate. Further, a reinforcing ring is formed from a strip of paper material in which the strip is partially overlapped and joined in the region of the overlap. The reinforcing ring is provided with a peripheral frame, which forms a circumferentially circumferential shoulder on a radially inner side of the reinforcing ring, and / or the reinforcing ring is provided with a circumferential bead. The peripheral heel and / or the circumferential bead serve to create a defined position of the lid when placed on a cup with a mouth roll, in which the paragraph snaps behind the mouth roll of the cup or snaps the mouth roll into the bead or behind the bead. Due to the circumferential shoulder or the bead, a defined position of the lid is thereby created on the cup, and yet the lid can still be removed from the cup without destruction. The mouth roll of the cup can be seen in cross-section circular or oval by a mouth roll is flattened.

The reinforcing ring is connected by means of a peripheral frame with the base body, said frame, which connects the base body with the reinforcing ring, is arranged above the cover plate, ie on one side of the cover plate of the base body, which faces away from the container to be closed.
