Description

  The present invention relates to a plastic container for beverages used as a container for non-carbonated beverages such as tea, water, fruit juice beverages, and sports drinks, and particularly when a longitudinal compression load is applied, the bottle bends (a longitudinal compression load is applied to the container). The present invention relates to a plastic container for beverages that is less deformed such that the container main shaft tilts sideways with respect to the container main shaft when no load is applied, and has little bottom deformation such as buckling at the bottom of the container.

  PET bottles (polyethylene terephthalate resin bottles) are frequently used as plastic containers for beverages used as containers for non-carbonated beverages such as tea, water, fruit juice beverages, and sports drinks.

  Conventionally, when hot-filling a PET bottle with the contents, the bottom of the container is not stretched, which causes a problem of heat shrinkage due to heating by the high-temperature contents, or heat to the outside of the container due to the weight of the contents. There has been a problem that the internal capacity changes due to deformation.

  In order to cope with these problems, a technique has been disclosed in which a gate entrance portion in which the bottom of the container is recessed inward is provided, and a plurality of substantially spherical ribs are radially arranged in the entrance portion (for example, Patent Document 1). Or see 2).

  In addition, in a container having a peripheral annular protrusion on the bottom and a recess on the inside thereof, there is a technique for forming a groove that communicates the space below the recess and the space outside the peripheral annular protrusion (see, for example, Patent Document 3). reference.). In the technique of Patent Document 3, the groove portion has a shape that crosses the peripheral annular protrusion, but the purpose of forming the groove portion is to allow the heated and expanded air that tends to accumulate in the space below the recess to escape easily during hot filling. It is to make it. As a result, it is difficult for the container to slide on the lifter.

  By the way, plastic containers for beverages are strongly demanded to be lighter and thinner in terms of environment and cost. On the other hand, plastic containers for beverages are transported and stored in cardboard boxes in units of several to several tens. However, since cardboard boxes are stacked at this time, longitudinal compressive load is applied to plastic containers for beverages. It takes. When a longitudinal compression load is applied, there is a demand for a plastic container for beverages that has little bottle bending and little bottom deformation such as buckling at the bottom of the container.

  In both cited documents 1 and 2, in order to prevent thermal shrinkage or thermal deformation due to heat received from the contents during hot filling, a spherical rib is further provided in the concave portion at the center of the bottom to improve the strength of the concave portion. It is a technology. Further, cited document 3 is a technique for releasing heated and expanded air that tends to accumulate in a concave portion recessed inward of a container provided at the center of the bottom, although a rib-like groove is provided in the peripheral annular protrusion. Therefore, none of the cited references 1 to 3 is a technique for reducing bottom bending such as buckling at the bottom of the container when the longitudinal compression load is applied, thereby reducing bottle bending. Here, once the bottom portion of the container buckles during loading in a warehouse or the like in logistics, a trace of buckling deformation remains in the container, reducing the aesthetic product value.

  In particular, a container filled with a non-carbonated beverage has a lower buckling strength at the bottom of the container than a carbonated beverage product filled at a high internal pressure because the internal pressure is reduced or normal pressure. It is desirable to have. Furthermore, a large-capacity plastic container of 1 to 2 liters, for example, a 1.5 liter or 2 liter large-capacity plastic container for beverages, has a square shape (horizontal cross-sectional shape has dropped corners in consideration of storage properties in a refrigerator or the like In many cases, the rectangular container is also desired to have a buckling strength.

  In addition, there is a technique for preventing the deformation of the bottom by providing a groove-like rib that circulates in the horizontal direction below the body of the container. However, when a longitudinal compression load is applied, the groove-like rib is used as a starting point. There is a problem that is easy to bend.

  Accordingly, an object of the present invention is to provide a beverage plastic container for filling non-carbonated beverages, while preventing bending of the container when a longitudinal compression load is applied, and reducing bottom deformation such as buckling at the bottom of the container. It is to be. Another object of the present invention is to provide a non-carbonated beverage product that is less likely to cause a decline in aesthetic product value using this container.

As a result of intensive studies to solve the above-described problems, the present inventors have arranged a plurality of small recesses that are recessed inward in the container along the ring of the ground surface on the ground surface of the container bottom.

  Embodiments of the present invention will be described with reference to the accompanying drawings. The embodiment described below is an example of the configuration of the present invention, and the present invention is not limited to the following embodiment. Various modifications may be made as long as the effects of the present invention are achieved.

  FIG. 1: is a general-view figure which shows the 1st form of the plastic container for drinks concerning this embodiment, (a) is a left view, (b) is a front view, (c) shows a top view. FIG. 2 is a perspective view of the container shown in FIG. The beverage plastic container 100 according to the present embodiment shown in FIGS. 1 and 2 has a mouth part 1, a shoulder part 2, a label part 3, a trunk part 4 and a bottom part 5 in order from the top, and the trunk part 4 Is a beverage plastic container for filling non-carbonated beverages having a long side wall 6, a short side wall 7, and a corner wall 8 connecting the long side wall 6 and the short side wall 7. First, the shape of the entire container will be described.

  The mouth portion 1 is usually formed with a diameter of 1.5 to 4 cm so that the beverage of the contents can be easily poured, and the shoulder portion 2 is connected to the label portion 3 having a larger trunk diameter toward the label portion. The diameter is expanded to form a cone. In addition, although the shoulder part 2 of the container shown in FIG.1 and FIG.2 is formed from the some cut surface, you may form in a curved surface. The label portion 3 is provided with a product display label such as a shrink label or a roll label on the outside thereof. The label portion 3 has an annular rib 27 that circulates in the horizontal direction. Further, the label unit 3 has a reduced pressure absorbing unit 28 that also serves as a gripping emboss. The body part 4 is a place that is mainly gripped by the consumer, and is provided with a body diameter that is substantially the same as that of the label part 3, or has a longer side and a shorter side than the label part 3 in order to prevent the label from rubbing. Both are given a diameter of about 1 mm larger. And the trunk | drum 4 has the embossing part 15 for a holding | grip, the transverse wave-shaped rib 9, and the cyclic | annular rib 26 which circulates in a horizontal direction. The gripping embossed portion 15 is preferably provided at the center of the long side wall 6 at the upper end portion of the body portion 4. The depth of the embossing portion 15 for grip is 8 to 18 mm, for example. The bottom part 5 is provided with a plurality of vertical ribs 29 to improve the strength, and realizes a self-supporting type. The annular ribs 26 and 27 are shallow groove-shaped ribs at the corner wall 8, and are groove-shaped ribs deeper than the long-side wall 6 and the short-side wall 7. Specifically, the annular ribs 26 and 27 are ribs having a U-shaped cross section at the corner wall 8, and ribs having a V-shaped cross section at the long side wall 6 and the short side wall 7. The rib having a V-shaped cross section is a two-step rib that is deeper than the rib bottom surface of the wall surface 8.

  Plastic containers for beverages are obtained by blow molding, preferably biaxial stretch blow molding. The plastic material for beverages is preferably made of PET resin, but other thermoplastic resins may be used as necessary.

  The plastic container for beverages according to this embodiment does not exclude the form of a round container having a circular bottom, but a form of a large-sized and square container having an internal capacity of 1 to 2 liters is suitable. The form which is a container with a capacity | capacitance of 1.5-2 liters which especially requires buckling strength is suitable. Since it has a square shape, it is composed of a long side wall 6, a short side wall 7, and a corner wall 8 as shown in FIGS. 1 and 2. In addition, the shape whose long side 6 and the short side of the short side wall 7 are the same length, ie, a square shape with a substantially square cross section, may be used. In large and square containers with an internal capacity of 1 to 2 liters, the ground contact surface at the bottom also has an annular square shape, and stress due to longitudinal compression load tends to concentrate at the corners of this square shape. Deformation can be reduced. Moreover, as shown in the plastic container 100 for drinks of FIG.1 and FIG.2, the corner wall 8 is made into the R surface whose horizontal cross section is circular arc shape or elliptical arc shape, and the boundary 24b and short side of a long side wall and a corner wall are short.

Also, the corners of the corner wall may be chamfered, and the boundary between the long side wall and the corner wall and the boundary between the short side wall and the corner wall may be on a curved surface instead of a bent portion (not shown). By making the corner wall a shape with chamfered corners, a cut-like appearance can be given. The corner wall can be elastically deformed by having a circular rib that circulates horizontally while having a pillar structure that supports a longitudinal compression load.

  Specific dimensions of the plastic container for beverages according to the present embodiment are, for example, a plastic container having a height of 200 to 370 mm, a body diameter extrapolated by a rectangle, that is, a rectangle surrounded by a tangent line between a long side wall and a short side wall. The approximate body diameter is (60 to 120) × (60 to 100) mm, and the body thickness is 0.10 to 0.30 mm. In the case of a bottle for aseptic filling, the barrel thickness is preferably 0.10 to 0.30 mm. Moreover, it can also be set as the container for hot filling, In this case, it is preferable that a trunk | drum thickness shall be 0.20-0.50 mm. The present invention is suitable as a aseptic filling bottle that is required to have a thin wall thickness when the barrel thickness is 0.10 to 0.30 mm. A plastic container having a capacity of less than 1 liter can be dealt with by reducing the size while maintaining a similar shape based on the plastic container having the above dimensions.

  Next, the bottom 5 will be described in detail. FIG. 3 is a schematic view for explaining the bottom of the plastic container for beverages according to this embodiment, wherein (a) is a bottom front view, (b) is a right side view, and (C) is a bottom view. 4 is a cross-sectional view taken along line AA in FIG. FIG. 5 is a schematic view of the bottom of the container shown in FIG. 1, (a) is a bottom front view, and (b) is a perspective view of the bottom. As shown in FIGS. 3, 4, and 5, a beverage plastic container 100 according to the present embodiment is a container that is a bottom surface of a bottom portion 5 in a beverage plastic container for filling non-carbonated beverages that is stretch-molded. A central recess 51 in which the center of the bottom 5a is recessed in the container, a grounding surface 53 that surrounds the central recess 51 and is annularly provided along the peripheral edge 52 of the container bottom 5a; A plurality of small recesses 54 that are arranged along the ring of the ground surface 53 and are recessed in the container.

  As pointed out in Patent Document 1 or 2, the center recessed portion 51 is not easily stretched at the bottom portion 5, and therefore the center portion of the container bottom portion 5a is recessed in the container in order to improve the strength. Since the central recessed portion 51 is provided, the ground contact surface 53 surrounds the central recessed portion 51 and has an annular shape along the peripheral edge 52 of the container bottom portion 5a.

  The small recess 54 is recessed in the container direction. By being recessed in the container, the ground contact surface 53 comes into contact with the floor. The shape of the edge of the small recess 54 is preferably circular or elliptical. When the diameter (in the case of a circle) or the major axis (in the case of an ellipse) of the small recess 54 (hereinafter simply referred to as “diameter”) is, for example, 2.0 to 10.0 mm, preferably 4.5 to When it is 6.0 mm and is oval, it is, for example, 2.0 to 10.0 mm, preferably 4.5 to 6.0 mm. When the diameter of the small recess 54 is less than 2.0 mm, the bottom deformation suppressing effect due to the provision of the small recess 54 on the ground contact surface 53 may be reduced. When the diameter of the small recess 54 exceeds 10.0 mm, In some cases, the area of the ground contact surface 53 is reduced, and the stress tends to concentrate on a specific location. The diameter of the small recess 54 is preferably smaller than the width of the ground contact surface 53. By making the diameter of the small concave portion 54 smaller than the width of the ground surface 53, the edge of the ground surface 53 and the edge of the small concave portion 54 can be arranged so as not to overlap with each other. It is easy to improve the strength of the ground. In addition, since the portion that mainly receives the longitudinal compressive load is both the edge of the ground contact surface and the edge of the small recess, the stress can be dispersed. The depth of the small recess 54 is, for example, 1.0 to 4.0 mm, preferably 1.5 to 2.5 mm. If the depth of the small recess 54 is less than 1.0 mm, the effect of suppressing bottom deformation due to the provision of the small recess 54 on the ground contact surface 53 may be reduced, and the depth of the small recess 54 exceeds 4.0 mm. And molding may be difficult.

  A plurality of small recesses 54 are arranged on the ground surface 53. As an arrangement pattern thereof, for example, as shown in FIG. 6A and 6B are schematic views showing another form of the arrangement of the small recesses, where FIG. 6A is a form arranged in two rows along the ring of the ground plane, and FIG. 6B is a staggered arrangement along the ring of the ground plane. The form to do. As shown in FIG. 6A, the plastic container for beverage according to the present embodiment is arranged in two rows along the annular shape of the ground contact surface 53 as an arrangement pattern of the small recesses 54, or FIG. As shown in FIG. 4, the pattern of the small recesses 54 may be arranged in a zigzag pattern along the ring of the ground contact surface 53.

It is preferable that the adjacent small recesses 54 are not in contact with each other and are independent. Furthermore, it is preferable that the edge shape of the small recesses 54 is circular, and satisfies the relationship of (Equation 1) where D is the distance between the centers of adjacent small recesses and r is the radius of the small recesses.
(Equation 1) 2r <D ≦ 30r
If 2r <D is satisfied, the edges of the small recesses 54 do not contact each other. If D exceeds 30r, if the plastic container for beverages is square, it is difficult to dispose at least one small recess 54 at each of the four corners of the container bottom 5a. By satisfy | filling Formula 1, the edge of an adjacent small recessed part does not overlap, and the effect by a small recessed part is fully exhibited.

  As shown in FIG. 3, a plurality of groove-like ribs 55 that traverse the ground contact surface 53 may be provided in a radial direction centered on the center 5b of the container bottom 5a. The rib 55 indicates that the bottom 5a of the container is deformed when a force that causes the central recessed portion 51 to be further depressed in the inner direction of the container, or when a force that causes the inner pressure to increase and the outer recessed part acts outward. Suppress. Since the rib 55 is provided for the purpose of improving the strength, it is preferable to increase the rib depth as a V-shaped cross section. The width of the rib 55 is, for example, 2.0 to 12.0 mm, preferably 5.0 to 9.0 mm, and the depth of the rib 55 is, for example, 2.0 to 5.0 mm, preferably 2.5 to 3 mm. .5 mm. The rib 55 crosses the ground contact surface 53, and as shown in FIGS. 3B and 3C, the end of the rib preferably forms a vertical rib 29.

  In FIG. 3, four small recesses 54 are arranged between the ribs 55 on the long side wall 6 side and the short side wall 7 side, respectively, and two small recesses 54 are arranged between the ribs 55 on the corner wall 8 side. The form was shown. The plastic container for beverages according to this embodiment is not limited to this arrangement, and the number of the small recesses 54 may be different. For example, two long recesses are arranged between the ribs on the long side wall side and the short side wall side shown in FIG. 7, and one small recess is arranged between the ribs on the corner wall side, and There is a configuration in which three small concave portions are arranged between the ribs on the long side wall side and the short side wall side shown in FIG. 8, and one small concave portion is arranged between the ribs on the corner wall side. By changing the number of small concave portions arranged, D in (Equation 1) can be changed. Since a force that deforms the bottom is easily applied to the four corners when a vertical compressive load is applied, as shown in FIGS. 3, 7, and 8, small recesses 53 must be arranged at the four corners on the corner wall 8 side. Is preferred.

  FIG. 9 is a perspective view of the bottom showing another form of the arrangement of the small recesses and the ribs. In the beverage plastic container according to the present embodiment, as shown in FIG. 9, a plurality of ribs 58 crossing the ground contact surface 53 are provided in a radial direction centered on the center 5 b of the container bottom 5 a, and the rib 58 is interposed between the ribs 58. It is preferable to arrange the small recesses 54 one by one. More specifically, long ribs 56 and short ribs 57 are provided as the ribs 58, and the long ribs 56 and the short ribs 57 are alternately arranged along the annular direction S of the ground contact surface 53. One small concave portion 54 is arranged between each of them. The depth of the long rib 56 is preferably deeper than the depth of the short rib 57. By adopting the form of the bottom shown in FIG. 9, the reinforcement of the bottom by the groove-shaped ribs in the radial direction and the reinforcement of the bottom by the small recesses are performed in a well-balanced manner.

  The plastic container for rectangular beverages according to the present embodiment is suitably used for products filled with non-carbonated beverages, especially for volumes of 1 to 2 liters, and further for volumes of 1.5 to 2 liters.
