[Industrial applications]

 The present invention relates to a pull pick in a pool open can, and more particularly to a pull pick in a pool open can that can seal an opened can opening.

[0002]

[Prior art]

 In recent years, pool open cans have been widely used as packaging containers for various items (eg, foods, beverages, oil solutions, etc.), but the contents are not used up at once after the pulling knob is opened. In many cases, the contents often come into direct contact with the air and then become less fresh, or dust and other substances infiltrate through the openings to contaminate the product, and it is often necessary to finally dispose of it. Becomes waste that can easily damage people, which is not desirable in terms of resource saving and waste disposal. Therefore, in order to temporarily store the contents that cannot be used all at once, various improved structures have been designed as follows.

The example shown in FIG. 3 is an illustration of a mouthpiece proposed in Taiwan Patent Application No. 8120358, which mainly has a bottom area slightly larger than the opening of a pool open can and a knob 101 provided at the top. The plate 10 and the latch 11 are integrally connected to each other, and the ratchet 11 has a T shape and is vertically connected to the bottom surface of the plate 10, and has a horizontal locking portion 112 at the lower end of the vertical center portion 111. By connecting the latches 11 at right angles to each other, the latch 11 is inserted from the opening and the knob 101 is rotated, and after the latch 11 is engaged with the peripheral edge of the opening, the hand is released and the corresponding plate 10 is completely opened. Although it is covered and sealed, it has a high manufacturing cost and it is inconvenient to always carry it around.

The example shown in FIG. 4 is an illustration of a proposal for Taiwan patent application No. 80203771, in which the conventional can lid 20 and the pulling knob 21 are approximately the same size as the can lid 20 and are detachable. A canopy cover 22 that can be fitted on the can lid 20 is provided as much as possible, and the canopy lid 22, the pulling knob 21, and the can lid 20 are integrally connected to each other by rivet joints so that dust can be collected on the can lid 20. The cover 22 is prevented from being covered, and the pulling knob 21 follows the action of pulling open the opening 201 of the can lid 20 to disengage the canopy lid 22 from the can lid 20. Since the lid 22 is added, the manufacturing cost is high, and the cap 22 has only the function of preventing dust from covering the upper surface of the can lid 20 before opening.

Further, the example shown in FIG. 5 is an illustration of the Taiwan patent application No. 81205670, which is mainly made of an elastically deformable material such as plastic rubber and has a pull knob 302 connected to the inside thereof. A hermetic seal 301 is installed, a male screw portion 303 is formed on the outer peripheral surface of the upper end, and a lower end edge of the elastic end portion 304 is formed as a divergent expandable end portion 304, which extends downward from the expandable end portion 304 and curls outward. A lid nipple 30 which is formed with a convex edge 305 and is fitted and fixed to the opening edge of the can lid 39, and a female screw portion 311 is provided on the inner peripheral wall having a substantially cylindrical shape, and the upper end is used as the outer lid pulling knob 312. The screw lid 31 is formed and screwed into the male screw portion 303 on the outer peripheral surface of the lid nipple 30.

Then, the lid nipple 30 is pushed into the can by using the elastic deformation function of the extending end portion 304 and is sunk, and the screw lid 31 is screwed to the lid nipple 30 and the can lid is held. 39 Fixed on the surface. When opening the can, first, the screw lid 31 is loosened and removed, and the lid nipple 30 is extended by elastic recovery of the expandable end 304, and then the pulling knob 302 of the lid nipple 30 is pulled to remove the can. The opening appears.

On the other hand, when it is necessary to store the contents that have been left unused, the screw lid 31 may be screwed back into the lid nipple 30 to achieve an excellent storage function. However, this type of construction is high in production cost, has few materials that can form the elastic end portion 304 of the lid nipple 30 and can be used for food, and is not suitable for powder or granules, and is applied only to liquid containers. Therefore, the range of use is limited.

SUMMARY OF THE INVENTION In consideration of the problem of pulling and picking in the conventional pool open can described above, the present invention has a temporary fresh-keeping function in which the contents do not easily overflow and foreign matters do not easily enter. The purpose of the present invention is to provide a pull pick for a pool open can that can be produced by using the existing equipment as it is and reduce the production cost.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention faces the outer edge of the opening of a pool open can, which was previously marked with a loop by a stamping press or the like, and rivets the pressing portion at one end so as to overlap the opening. And a pressing convex edge for pressing and opening the opening is formed in a portion of the pressing portion that overlaps the opening, and the opening is provided at the other end sandwiching the pivot point of the rivet joint. It is configured by forming a pulling portion having a lid surface that can be covered and a hooking edge that floats to a predetermined width around the lid surface.

[0010] The downward facing lid surface of the pulling portion is formed to have a size to be anastomosed with the opening so that the upper surface of the opening can be crimp-fitted; and the lid surface covering and covering the opening. It is more preferable to form a flange-shaped convex edge extending outward from the hooking edge on the outer peripheral edge.

[0011]

[Action]

 According to the present invention configured as described above, when the pulling upper portion is scratched and picked up, the pressing portion presses the opening portion of the can lid by a levering action with the pivot point as a fulcrum to open it. The contents can be used from this crimped and opened opening.

Further, when it is desired to temporarily store the contents without being used up, the pull knob is rotated about the pivot point so that the lid surface of the pull upper portion corresponds to the can opening and It suffices to press the bottom surface of the lid into the opening for fitting and attachment, and when reusing the contents stored in the can, use the hooking edge of the pull knob to pull the pull. The contents can be reused by pulling up the knob to separate the bottom surface of the lid from the opening of the can lid and rotating the pulling knob to an appropriate position around the pivot point.

The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description of the embodiments with reference to the drawings.

[0014]

【Example】

 FIG. 1 shows a comparatively preferred embodiment of the present invention. As shown in the drawing, the pulling knob 4 of this embodiment has a rivet at an appropriate position around the opening 91 of the can lid 9 of the pool open can. The pull tab 4 has one end pivotally attached to the rivet joint formed on the pressing portion 42 and one end edge of the other end edge. A portion is formed on a hooking edge 41 that floats above the upper surface of the can lid 9 so that the pulling knob 4 can be easily scratched and picked, and a downward pressing point 421 is provided on the bottom surface of the pressing portion 42.

The pulling knob 4 has an end portion facing the hooking edge 41 facing the pressing portion 42, provided on the pulling upper portion 43, and a recessed lid surface 431 is provided on the pulling upper portion 43, and Provided below the lid surface 431 is a convex surface that is slightly smaller in shape than the opening of the can lid 9 protruding downward from the bottom surface of the pull lid 43, and makes the area of the pull top 43 larger than the opening 91 of the can lid 9. .

The pulling portion 43 is made to have an appropriate thickness, and in particular, the neck portion 439 approximately midway between the pivot point 8 and the lid surface 431 is provided to have sufficient elasticity and toughness. Since the lid surface 431 adjacent to the neck portion 439 of the pulling portion 43 is recessed so as to have considerable structural stress, the pulling portion 43 as a whole has high elasticity and toughness.

When the pool open can is opened, first, the pulling upper portion 43 of the pulling knob 4 is scratched and picked up, and the pulling knob 4 uses the pivoting point 8 as a fulcrum to push the pushing portion 42. Presses the opening 91 of the can lid 9 to open, and the contents can be used from the opened opening that is pressed, and at the same time, the pulling part 43 has high elasticity and toughness. Therefore, the pulling-out portion 43 rebounds from the structural stress of itself so that the pulling-up portion 43 may be attached again to the can lid 9.

After that, when it is desired to store the contents for a while without using up the contents at one time, the pulling knob 4 is rotated around the pivot point 8 so that the lid surface 431 of the pulling part 43 is rotated. Since the convex surface at the bottom of the lid surface 431 is provided to be slightly smaller than the opening shape so as to correspond to the opening portion 91, the lid surface 431 can be pushed and fitted into the opening, and the pulling portion Since 43 is attached to the upper surface of the can lid 9, the opening 91 can be tightly sealed to store the contents.

On the other hand, when the contents stored in the can are reused, the pulling tab 4 is pulled up by using the hooking edge 41, and the convex surface at the bottom of the lid surface 431 of the can lid 9 is pulled. The contents can be reused by removing the pulling knob 4 from the opening 91 and rotating the pulling knob 4 to an appropriate position around the pivot point 8.

That is, the present invention is to improve the pulling knob of the pool open can so that the residue in the can that cannot be used up at one time can be sealed and stored, and the pulling knob 4 is a general pool open can. It is made of the same material as the can (for example, aluminum material) or a plastic material that does not cause chemical changes to the contents inside the can, and is attached to the pool open can during the conventional manufacturing process for pool open cans. It can reduce the production cost and increase the competitiveness of products.

FIG. 2 is a sectional side view of the recessed lid surface 431 of the pulling upper portion 43 in the pulling knob 4, the size of which corresponds to the opening shape of the can lid 9 and the outer circumference thereof. Since the side surface has a tapered peripheral surface 432 which is slightly inclined inward, when the lid surface 431 of the pulling portion 43 is pushed in corresponding to the opening of the can lid 9, the lid surface 431 is easily slid into the opening of the can lid 9. It can be inserted and fitted, and the pulling portion 43 of the pulling knob 4 can be tightly attached to the peripheral edge of the opening of the can lid 9 to fulfill the purpose of temporary sealing.
