Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in a packaging container for storing articles such as snacks, which can be used by being assembled into a packaging container such as a beverage can.

(Prior Art) Generally, when consumers purchase canned beer or liquor from vending machines or at stores, they have to purchase and prepare snacks separately, which is a hassle.
Snack packaging containers usually have a disadvantage in that they contain more knobs than the capacity of the beer, making it difficult to dispose of the leftovers.

For this reason, for example, as proposed in Utility Model Publication No. 37-21480, Utility Model Publication No. 55-18267, Utility Model Publication No. 51-155255, etc., lids are attached to the upper or lower edges of packaging containers such as canned goods and bottles. There is a packaging container containing an appropriate amount of tabs that can be assembled and installed by fitting the opening edge of the container.

In this type of packaging container, an annular step portion is provided that projects inward in the circumferential direction at a distance from the opening edge of the packaging container, and the step portion is engaged with the recess formed by the lid attachment portion. I stopped and assembled it.

However, since this type of container stores items such as snacks, there is a risk that the packaging container will come off during transportation, etc., unless the stepped part and the recess are securely engaged. If the lock is strong, it will be difficult to remove during use.On the other hand, if the lock is loose, removal will be easy during use, but the packaging container will easily come off during transportation. It was difficult to adjust.

(Problems to be Solved by the Invention) The present invention solves these conventional drawbacks, and does not easily detach even if an unexpected force is applied during transportation.
To provide a packaging container for assembly that can be easily removed by hand during use.

(Means for Solving the Problems) For this reason, the present invention provides a packaging container 1 containing an article to be attached by fitting the opening edge 6 around the entire circumference of the lid attachment part B at the upper or lower end of the packaging container A. It is composed of the opening edge 6, a shelf 11 that comes into contact with the top of the lid attachment part B, a hanging part 12 along the outside, and an opening edge 2 continuous to the hanging part 12, and between the hanging part 12 and the opening edge 2. Bead groups 3 with a wave-shaped cross section extending perpendicularly to the full width of the bead are provided at two or more locations at intervals in the circumferential direction, and the hanging portion 12 is placed in pressure contact with the outside of the lid attachment portion B between the bead groups 3. In addition to providing the hanging portion 12
A step portion 4 is provided at the lower end of the lid attachment portion B to engage with a recess portion C formed by the lid attachment portion B.

(Example) A detailed explanation will be given below with reference to FIGS. 1 to 3 showing an example of implementation of the present invention.

What is shown in the figure is a packaging container 1 of the present product attached using the lid attachment part B on the upper edge of a beverage can A. This has an opening edge 2 on one side, and the opening edge It consists of an opening edge 6 which is connected to the opening edge 6 and is bent into a roughly L-shaped cross section, and a bottomed container body 7 which is connected to the opening edge 6. As shown in the second figure, the opening edge 6 includes a shelf 11 that comes into contact with the top surface of the lid attachment part B, a hanging part 12 along the outer surface, and an opening edge 2 that is continuous with the hanging part 12.
It consists of Bead groups 3 of 3 or more vertical pitches each having a wave-shaped cross section extending perpendicularly to the full width between the hanging portion 12 and the opening edge 2 are provided at five locations with intervals in the circumferential direction, and each bead A gap 8 was provided between the inner surface of group 3 and can lid seam B.

As shown in FIG. 3, a step portion 4 extending in the circumferential direction and projecting inward is provided between the bead groups 3 and 3 at approximately the middle of the height of the bead group 3 and at the lower end of the hanging portion 12. The peripheral edge part 5 between the stepped part 4 and the opening edge 2 is shaped to expand outward so that it can be inserted with a finger when removing the present product. 10
is a lid made of a composite sheet material of aluminum foil and synthetic resin for sealing the opening of this product,
It is bonded to the inner surface of the shelf 11 of the opening edge 6. At least the inner surface of the hanging portion 12 extending from the shelf portion 11 of the opening edge portion 6 to the step portion 4 is inclined at an angle of 2 to 10 degrees with respect to the axis of the container body 7, as shown in the third figure. When the product is assembled into the beverage can A, the stepped portion 4 is locked into the recess C formed by the lid attachment portion B, and the hanging portion 12 is pressed against the lid attachment portion B while being firmly held against the shelf portion 11. I tried to keep it.

Reference numeral 13 designates an engaging portion embossed on the bottom of the container body 7 so as to be able to fit freely into the bottom of a beverage can A' having the same shape as the beverage can A.

Since the present product is configured as described above, when the present product is assembled to the beverage can A as shown in the first figure, the opening edge 6 is engaged with the lid attachment portion B at the stepped portion 4, and the shelf portion is 11 and the hanging part 12, the drink can is reliably and strongly assembled to the beverage can A. At the same time, the locking force of the step part 4 and the holding force of the shelf part 11 and hanging part 12 are adjusted by the elastic deformation function of the adjacent bead group 3, so that unnecessary pressing force is not applied to the product. It is also assembled to such an extent that it is difficult to detach. On the other hand,
When separating this embodiment during use, when attempting to release the locking of the stepped portion 4 by the peripheral edge 5 of the opening edge 6 and the holding of the shelf portion 11 and hanging portion 12 with fingers, the adjacent bead is removed. Group 3 is elastically deformed to facilitate this.

In this way, the bead group 3 is useful for adjusting the locking force of the step part 4 and the holding force by the shelf part 11 and the hanging part 12. That is, this bead group 3 extends perpendicularly to the entire width between the hanging portion 12 of the opening edge 6 and the opening edge 2, and is provided between the stepped portions 4 with a relatively large interval. Therefore, it is easy to elastically deform when the opening edge 2 is grasped with fingers to spread the stepped portion 4 outward, but it is difficult to elastically deform when other external forces are applied. Further, it is preferable that this bead group 3 not be brought into contact with the lid attachment part B on the inner surface side, but to provide a gap, so that the bead group 3 can be easily elastically deformed.
and the number of locations where bead group 3 is provided and bead 3
The number of waves forming the cross-sectional wave shape is determined by considering the material, thickness, etc. of the synthetic resin used to form this product. The number of waves in each is at least 3
Requires at least one pitch (one pitch from top to top).

(Effect of the invention) As is clear from the above explanation, when the present invention is used, the opening edge 6 is fitted around the entire circumference of the lid attachment part B at the upper or lower end of the packaging container A to store the article to be attached. In the packaging container 1, the shelf 11 of the opening edge 6 is provided in contact with the top of the lid attachment part B, and the hanging part 12 connected to this is provided in a position where it presses against the outside of the lid attachment part B. Since the stepped portion 4 that engages with the recess C formed by the lid attachment portion B at the lower end is provided, the locking force of the stepped portion 4 and the shelf portion 11 on the lid attachment portion B are
The holding force of the hanging portion 12 allows for reliable assembly, and the stepped portion 4 has a bead group 3 with a wave-shaped cross section extending perpendicularly to the entire width between the hanging portion 12 and the opening edge 2.
Even if the stepped portion 4 is relatively long in the circumferential direction and the locking force and holding force are large, when the lower opening edge 2 of the stepped portion 4 is expanded outward with fingers, the bead Due to the elastic deformation of the group 3, the engagement of the stepped portion 4 can be easily released and removal is simple, and on the other hand, even if an unexpected external force is applied in addition to such an operation, the group 3 can be easily disengaged. This has the effect of providing a packaging container that can be assembled freely without any problems.
