SUMMARY OF THE INVENTION The connecting device for cans invented above is an integrated molding of synthetic resin having an upper plate, a cylindrical portion on the outer periphery of the upper plate, and a concave portion formed on the upper surface of the upper plate. Using a connecting member made of a product, the cylindrical portion is press-fitted or screwed into the upper portion of the can, and the lower portion of the other can is press-fitted or screwed into the concave portion, and the plurality of cans are vertically moved. This is extremely effective in that a plurality of cans can be firmly connected vertically and a stable stacked display is possible. However, in the case of a can whose upper part is slightly conical with a vase (there are many beer cans), simply press-fit the upper part of the can into a cylindrical part. If the can is pulled out by vibrations, etc., the upper part of the can is screwed into the cylindrical part, but there is no danger of the can getting out as described above.However, a female screw is provided on the inner peripheral surface of the cylindrical part. In addition to this, there is a troublesome problem that a male screw must be formed on the outer periphery of the can upper part.In addition, when connecting and disconnecting, it is necessary to perform operations such as screwing in and loosening the screws one by one. Has the problem that it is troublesome.

[0004] The present invention aims to address the above problems.

SUMMARY OF THE INVENTION The present invention has a lower tubular portion and an upper tubular portion which are press-fitted into upper and lower portions of a can, respectively, on the outer periphery of a partition plate portion, and are provided on the lower surface of the partition plate portion. A connecting member consisting of a synthetic resin integrally molded product having an annular groove into which the caulked portion of the body upper end and the upper end face plate of the can is fitted and locked, and the connecting member is used to vertically cascade a plurality of cans. A flange portion having a plurality of vertically recessed grooves having a cross-sectional shape with a wide depth is formed integrally on the outer periphery of the lower tubular portion and the upper tubular portion of the connecting member, and connected together. A plurality of cans stacked vertically and connected by a member are arranged side by side in the front-rear and left-right directions, and the vertical grooves of the adjacent connecting members are joined to each other. Insert a connecting piece with a cross-sectional shape that almost matches the cross-sectional shape of the groove up and down. By passing, it is characterized in that it has to be connected in parallel a plurality of cans to and fro.

[0006]

According to the above, when the lower cylindrical portion of the connecting member is pushed into the upper portion of the can, the caulked portion of the upper portion of the can is fitted into the annular groove of the connecting member, and the upper portion of the body portion of the can is formed into a conical surface of the upper vault. Even if it is formed, it is firmly held so that it does not come out with the external force of the vibration level, and the two cans are stably stacked up and down by press-fitting the lower part of another can into the upper cylindrical part of the connecting member. In this way, a plurality of cans can be stacked and connected one above the other in multiple stages. Also, the can can be removed relatively easily and easily. Further, by inserting the connecting pieces into the vertically concave grooves which are arranged side by side in the front and back and left and right and connected in a stacked manner in this manner, a plurality of cans can be connected in parallel to the front and rear and left and right. As one block of a large size, handling such as transportation can be performed without a container such as a cardboard box, and stable stacked display is possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example in which the present invention is applied to a beer can which is generally sold and whose upper outer periphery is formed in a conical surface with a slightly upper bowl, where 1 is a can and 2 is a can. It is a connecting member made of a synthetic resin integrally molded product.

In the can 1, the body 11 and the bottom are integrally formed, and the upper part of the body 11 is formed as a conical surface part 11a which is slightly upwardly constricted. The structure is airtightly bonded by caulking, and almost all commercially available beer cans adopt this structure. 13 is a caulking portion.

The connecting member 2 includes a partition plate 21, a lower tubular portion 22 and an upper tubular portion 23 extending downward and upward from the outer periphery of the partition plate 21, respectively, and a lower tubular portion 22 and an upper tubular portion 23. A flange portion 24 is provided on the outer periphery of the boundary portion and has a plurality of vertical concave grooves 24a of a cross-sectional shape having a wider depth formed on the outer periphery, and a downward portion formed on the lower surface of the partition plate 21 near the outer periphery. It is formed into a structure having an annular groove 25.

The inner diameters of the lower cylindrical portion 22 and the upper cylindrical portion 23 are approximately adapted to the outer diameter of the can 1, and are set to such dimensions that the body 11 of the can 1 can be press-fitted. The annular groove 25 is formed into a shape having a width and a depth adapted to the caulking portion 13 of the can 1 by the inner peripheral wall 25a and the outer peripheral wall 25b and capable of fitting the caulking portion 13, and has a lower end portion of the outer peripheral wall 25b. Inward projection 2
5b 'is protruded over the entire circumference, and the width of the lower opening is narrowed by the protrusion 25b' so as to be slightly smaller than the thickness of the caulking portion 13.

In the above, the lower tubular part 22 of the connecting member 2 is fitted into the upper part of the can 1. Then, the caulked portion 13 at the upper end of the outer peripheral portion of the can 1 hits the projection 25b 'and presses it to cause the outer peripheral wall 25b to be deformed into a larger diameter while being fitted into the annular groove portion 25. 25b 'is pressed into engagement with the lower part of the outer periphery of the caulking portion 13 over the entire circumference, and the fitting state of the caulking portion 13 to the annular groove portion 25 is kept airtight or almost airtight. Next, the connecting member 2
The two cans are vertically connected by press-fitting the lower part of the body 11 of another can into the upper cylindrical part 23 of the can. In this way, a plurality of cans can be stacked and connected one after the other in multiple stages.

In this manner, the swaging portion 13 of the can can be simply and firmly fitted into the annular groove 25 simply by forcibly pushing the lower tubular portion 22 of the connecting member into the upper portion of the can. The work of press-fitting the lower part of other cans can easily and stably connect many cans vertically and reliably, and when removing the can from the connecting member, the upper part of the can is slightly attached to the connecting member. Since the caulking portion 13 comes out of the annular groove portion 25 by being pulled out while being pryed, the can can be easily and easily removed by almost one-touch operation.

Further, a plurality of cans 1 which are stacked and connected in multiple stages in the vertical direction by the connecting member 2 as described above are arranged in parallel, and the concave grooves 24a, 24a of the adjacent connecting members 2, 2 are put together. The two recessed grooves 24 that have been brought together
1A, a connecting piece 3 made of synthetic resin having a cross-sectional shape substantially matching the cross-sectional shape of the two recessed grooves 24a, 24a, as shown in FIG. By inserting the cans, a plurality of cans stacked and connected in a plurality of stages vertically can be connected in parallel in front, rear, left and right. As described above, the connecting piece 3 inserted into the concave grooves 24a, 24a is prevented from coming off by bending its upper end and lower end, for example, as shown in FIG. 2 and fitting it back into another concave groove 24a.

[0015] In this manner, cans of the number of ordinary sales units, such as half dozen, one dozen or a plurality of dozens, can be connected together in blocks in up, down, front, back, left and right. Products can be transported and displayed and sold as they are, and the person who bought them can be brought back as they are.

In recent years, various objects have been created by combining these three-dimensionally using empty cans. In this case, the use of the empty can together with the connecting member and the connecting piece of the present invention has led to the creation of various objects. Combination and connection of empty cans becomes easy, and creation of complicated objects can be facilitated.

[0017]

As described above, according to the present invention, cans can be vertically connected in a plurality of stages by a connecting member made of a synthetic resin integrally molded product, and the cans can be connected to the front, rear, left and right by the connecting members and connecting pieces. Can be securely connected in parallel, so that dozens of cans can be packed into just the right size for carrying, transported without containers such as cardboard boxes, stored in warehouses, or displayed. It is easy and easy to connect and remove a plurality of cans together, which can bring about an effect that handling of cans is very efficient and easy, and is also very useful for creating objects with empty cans. Thus, the practical effect is extremely large.
