BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a canned composite of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of a canned composite according to the present invention. In this embodiment, a canned composite 1 comprises:
Two small cans of the same shape and the same size 2,
3 are connected in series, and the overall size is substantially the same as that of a 500 ml long-sized beverage can in a two-piece can.

The respective cans 2 and 3 constituting the composite 1
Each of the can bodies is a two-piece can formed by squeezing the can body and can bottom from a metal disc such as a surface-treated steel plate (steel) represented by an aluminum alloy or a tin plate and forming the same integrally by ironing. The can lid having a tab with easy opening is integrally wound around the opening of the can body which has been subjected to the in-processing and the flange processing by the can lid winding portions 2a and 3a.

The can bottoms of the cans 2 and 3 are formed with concave portions 2b and 3b whose central portions bulge upward with respect to the peripheral portion, respectively, as in a general two-piece can. , 3 are formed slightly larger than the upper end portion of the can body including the can lid winding portions 2a, 3a in the can.

Then, at least the can 2 located at the upper side
On the bottom of the can, a plurality (three in the illustrated case) of engagement projections 2c are provided on the peripheral wall of the recess 2b at regular intervals in the circumferential direction as shown in FIG. They are integrally formed so as to protrude about 1 mm toward each other.

As a result, as shown in FIG. 3, each of the can projections 2c of the can 2 located above is overwhelmed by the can lid tightening portion 3a of the can 3 located below, so that each of the cans 2, 3
The elastically deformable engaging projections 2c formed on the peripheral wall of the concave portion 2b of the can bottom, which are considerably thicker than the can body and are relatively rigid, project outward and have high rigidity. By snap engagement with the can lid winding portion 3a, the can lid is detachably connected in series.

FIG. 4 shows that the can body of each of the cans 2 and 3 is further connected to one shrink film (heat shrinkable film) for the canned composite 1 in which the cans 2 and 3 are connected in series as described above. (A thermoplastic resin film) having a single body, and one shrink film 4 covering the can body of each can 2, 3 corresponds to a connecting portion of each can 2, 3. A cut line (perforation) 4a that can be cut is formed at the location.

When one shrink film 4 is covered over the respective can bodies of the plurality of cans 2 and 3, each canned product is compared with a case where a plurality of cans are simply packaged together in a shrink package. Since the pieces 2 and 3 are securely connected in advance, the work can be easily performed as in the case of covering the shrink film 4 on a single canned can body.

Further, the cans 2 and 3 connected to each other have a can body surface including a reduced diameter portion in close contact with one shrink film 4, so that the cans can be connected to each other even when subjected to vibration or impact during transportation. There is no disconnection.

According to the above-described canned composite 1 of the present embodiment, at least the can 2 located at the upper side, the resin applied to the inner wall and the outer surface in advance on the peripheral wall of the concave portion 2b of the can bottom. A plurality of engaging projections 2c having a projection height of about 1 mm that hardly damage the coating or make it difficult to coat later by coating (from the viewpoint of stability at the time of connection and easy separation). ５5 is preferable) By simply molding, each of the engaging projections 2c
The cans 2 and 3 can be easily connected to each other or separated from each other by simple operations such as push-fitting and pulling-out by snap engagement with the can lid winding portion 3a.

[0018] One product, such as the canned composite 1 thus connected, can be easily divided into a plurality of small cans 2 and 3. It is possible to prevent wasteful drinking, and when two people drink, they can be separated into individual cans.

Also, by changing the contents of each of the cans 2 and 3, for example, one of the contents is black coffee and the other is caffe ole, and different tastes are enjoyed by one product. Alternatively, one content may be an alcoholic beverage and the other content may be a snack adapted to it.

When connecting canned alcoholic beverages and canned snacks, if the snack foods are difficult to remove from the can, a simple open can lid with a full-open type is used for canned snacks. It will be.

In this embodiment, the normal size (35
0 ml), the cans 2 and 3 smaller than each other are connected to each other to have the same size as the existing 500 ml long size, so that when selling by a vending machine, it can be handled by existing vendors. It has become something.

Further, since the can body of each of cans 2 and 3 is integrally covered with one shrink film 4 with respect to the canned composite 1, it is almost the same as one long size beverage can in appearance. The product can be made like this, and at the time of handling at each stage until it reaches the consumer's hand, there is no concern that the connection between the cans 2 and 3 may be accidentally disconnected. Can be.

In addition, in correspondence with the connection of the cans 2 and 3 to each other so as to be relatively rotatable by snap engagement, the shrink film 4 is provided at a portion corresponding to the connection portion of the cans 2 and 3. Since the intermittent cut lines (perforations) 4a that can be cut are formed, the cut lines 4
By cutting a with a nail or a coin, or by directly grasping the upper and lower parts of the composite 1 and twisting it, the shrink film 4 can be easily cut at the cut line 4a. The composite 1 can be easily separated as cans 2 and 3 respectively.

The number of cut lines 4a may be two,
Further, for example, after the portion sandwiched between the two cut lines is pinched and broken by a finger, the composite 1
3 may be separated.

Furthermore, by providing characters and decorations corresponding to the contents of the cans at the positions corresponding to the cans 2 and 3 of the shrink film 4, the surfaces of the can bodies of the cans 2 and 3 can be provided. Text and decoration can be omitted. In the case where decorative printing is performed on the surface of the can body of each of the cans 2 and 3, decorative printing on the shrink film 4 can be omitted by making the shrink film 4 transparent. (In that case, it is only necessary to print on the shrink film 4 a description of how to disconnect the cans 2 and 3 and the like.)

As described above, one embodiment of the canned composite of the present invention has been described. However, the present invention is not limited to only the above-described embodiment. The number is not limited to two, but may be three, and the cans to be connected may not be the same in height but may be appropriately combined in different heights. The present invention can be applied not only to cans but also to three-piece cans.

Also, regarding the size of the canned composite,
In the above embodiment, the same size as the long 500 ml canned beverage can be used in general, so that the vending machine can handle it with existing vendors. It is also possible to carry out as the same size, and furthermore, if the handling by vending machines is not considered,
It can be implemented in any size.

Further, as the film integrally covering the canned composite, a film obtained by performing decorative printing by gravure printing on a thermoplastic resin film such as a polyester resin or a polypropylene resin instead of the shrink film is used. It is also possible to form a cut line that can be cut at a position corresponding to the connection portion of each can in the same manner as in the case of the shrink film.

However, in the case of such a thermoplastic resin film, the holding force of the composite is weaker than that of the shrinkable shrink film. It is desirable to bond to the surface.

[0030]

According to the canned composite of the present invention as described above, a plurality of small-sized cans can be separably united by a simple structure, whereby a plurality of cans can be combined into one can. It can be handled in the same manner as above, and with such a single product (complex), if you enjoy different tastes little by little when drinking alone, or if you drink separately by multiple people, Can be individually divided into one can, or each person can drink their favorite beverage.
