DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal can container capable of easily flattening a used metal can.

[0002]

2. Description of the Related Art In most cases, a metal can container for storing a liquid or the like has a structure in which a bottom plate and a top plate are integrally provided as end plates at both ends of a rectangular tube or a cylindrical tube. In order to secure it, the end of the cylindrical body and the peripheral end of the top plate and the bottom plate are wrapped around and assembled, and are extremely strong enough to withstand the gravity of the storage capacity.

[0003] The used metal cans, which have been used up after being used up, are properly disposed of as discarded products, but the processing is extremely time-consuming. That is, as described above, the assembly of the cylinder and the end plate is so strong that it cannot be easily crushed, and a dedicated crusher device has been developed. Will be done.

[0004] Therefore, since bulky empty cans must be transported to a predetermined disposal site, it is not only time-consuming but also extremely uneconomical. Even after being transported to this disposal site, if the waste is piled up for disposal, the space it occupies will be vast. Of course, it is meaningful to recover waste as a resource reuse, but there is a contradiction in which more resources, including labor, must be consumed for the reuse.

[0005]

In view of such conventional problems, there have been proposed, for example, Japanese Patent No. 2807971 "can" and Utility Model Registration No. 2518691 "can container".

[0006] The "can" of the above-mentioned Japanese Patent No. 28007971 is
`` On the periphery of the can bottom, via a rib having a semi-circular cross section in which an elastic sealing material is fitted into an inner groove, and form a number of standing-up fastening pieces that are divided by cuts formed at equal intervals,
Each of the fastening pieces is independently wound around the lower periphery of the can body. "

[0007] When the peripheral end is hit with a hammer or the like, each of the independently fastened and held fastening pieces is intermittent, so that they are extended from the fastened state and released, and the can bottom is opened. It is said that it will be easily detached from the can body.

However, this construction requires complicated molding and assembling work because of its complicated structure, and has a problem that the mounting strength is uneasy because it is a partly independent fastening and holding.
It is doubtful whether the elastic seal works effectively in places other than the individual tightening pieces, the hammer must be applied to each tightening piece over the entire circumference, and all the tightening pieces are released by hitting with the hammer However, since the can bottom and the can body are separate bodies, there are disadvantages and disadvantages such as an increase in the number of post-processing members and bulkiness.

[0009] Utility Model Registration No. 2518691 "can container" has a structure in which "a plurality of loop-shaped breaking grooves are formed near the body on the bottom surface, and the outer breaking grooves are formed on the inner circumferential side. Formed deeper than ".

When the bottom is hit with a mallet or the like, the bottom is broken from the trunk with the breaking groove as a boundary, and the bottom can be separated. In this case, the deeply formed outer peripheral side fracture groove facilitates the deformation fracture image of the inner peripheral side fracture groove.

However, this configuration is troublesome in that a plurality of breaking grooves must be formed, and the depth must be formed differently between the outer circumferential side and the inner circumferential side. In addition, the function of the deeply formed outer peripheral side groove for fracture is unclear, and the question of easiness of fracture remains, and since a plurality of grooves are formed, the content is stored and the weight is bulky. Drawbacks, such as the fact that there is still anxiety about whether the strength can be maintained in a state where it is in place, especially when there is a possibility that it will break because there are multiple grooves when it falls accidentally.
There are inconveniences.

Accordingly, the present invention has been developed to solve the above-mentioned drawbacks and disadvantages of the prior art. The present invention relates to a metal can container having an end plate connected to a cylindrical body, and has sufficient strength in use. It is an object of the present invention to easily achieve breakage of the peripheral edge of the end plate when the product is discarded, and to be able to flatten the end plate.

[0013]

In order to solve the above-mentioned problems, a metal can container according to the present invention has a score groove line for cutting cut along the periphery of an end plate of a metal can body. The groove portion of the section is made deep.

Therefore, when the end plate portion near the deep groove portion, which is a part of the score groove line, is hit with a mallet or the like, the deep groove portion breaks, and the shallow groove portion continuous therewith breaks in a chain. The entire score groove portion can be broken, and the tubular portion of the metal can can be crushed flat easily.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the drawings. In a metal can container according to the present invention, a top plate and an end plate 1 serving as a bottom plate are attached to both ends of a cylindrical body by, for example, winding and assembling. In the configuration, FIG. 1A shows a circular end plate 1 of a cylindrical container, and FIG. 2A shows a rectangular end plate 1 of a rectangular container.

In FIG. 1 (a), a score groove line 2 is engraved on a peripheral end of a disk-shaped end plate 1. In the illustrated embodiment, the score groove line 2 is not the entire periphery of the end plate 1, but is partially cut off to form a non-groove portion 3. May be applied to the entire circumference.

As will be described later, when the score groove 2 is broken by hitting the end plate 1, if the non-groove portion 3 is formed, the portion is naturally not broken. If it is continuous with the body and is applied endlessly without forming the non-groove portion 3, the score groove line 2 is broken over the entire circumference, so that the end plate 1 and the cylindrical body are separate objects. Becomes

The score groove line 2, which is substantially circular in FIG. 1 (a), has a deep groove portion 4 formed deeper than other portions in a portion of the end plate 1 opposite to the non-groove portion 3. The end plate 1 near the deep groove 4 is formed with a target portion 5 for printing a notice such as "Please hit here" or engraving it as a mark. .

FIG. 1B shows the deep groove 4 at the line AA in FIG. 1A, and FIG. 1C shows the shallow score groove 2 at the line BB.

Now, in the configuration of FIG. 1 described above, the disposal of the scrap metal can is performed by hitting the target portion 5 of the end plate 1 with a mallet or a hammer. That is, due to the impact, the portion of the deep groove portion 4 near the target portion 5 becomes thin, so that the portion is first broken, and the other shallow score groove line 2 portion is broken in a chain by continuous impact or manual pressing.

By this series of operations, the peripheral end of the end plate 1 is
A part of the score groove line 2 which is engraved over substantially the entire circumference is broken, and the broken non-breakable part 3 of the score groove line 2 is folded into, for example, a cylinder of a can. It is possible to obtain a flat waste product in which the cylinder 1 and the cylindrical body are integrated.

As a waste product, a flat form in which the end plate 1 and the cylindrical body are integrated is easier to treat, but a separate body may be better for reuse of the waste product. The score groove line 2 may be engraved over the entire circumference of the end.

Further, the end plate 1 must be broken on both the top plate and the bottom plate. However, depending on the product, the entire top plate may be broken and removed, and the contents may be taken out. The end plate 1 may be used only for the bottom plate.

Next, in FIG. 2 (a), score groove lines 2 are engraved on three sides of a peripheral end portion of a square plate-shaped end plate 1, and the remaining one side is cut off by the score groove lines 2 to form a non-groove portion. It is 3. As in the case of the previous embodiment, the non-groove portion 3 may be formed endlessly on the entire circumference without forming the non-groove portion 3.

In the score groove line 2 in FIG. 2A, a deep groove portion 4 is formed at one corner of the end plate 1 so as to be engraved deeper than other portions. The target portion 5 is formed at one corner of the end plate in the vicinity.

FIG. 2B shows the deep groove 4 at the line CC in FIG. 2A, and FIG. 2C shows the shallow score groove 2 at the line DD.

As is apparent from FIG. 2A, the score groove line 2 at the corner of the end plate 1 is separated from the peripheral end of the end plate 1, that is, the curve R has a large shape. And
For example, the CC line portion which is one corner of the end plate 1 and the adjacent corner portion, and the score groove line 2 near the non-groove portion 3 is also sufficiently separated from the corner of the end plate 1. . This is because the corners of the end plate 1 are susceptible to external impact, and therefore, if the score groove line 2 is close to this corner, the impact force is transmitted to the score groove line 2 and breaks unintentionally. This is because there is a fear.

The breaking operation is performed at the corner C-C at one corner of the end plate 1.
The process is started by breaking the deep groove portion 4 of the line portion, and is performed by hitting the target portion 5 in the vicinity thereof.
Then, as in the previous embodiment, the other shallow score groove lines 2 are broken in a chain due to continuation of hitting or pressing by hand.

[0029]

As described above, the metal can container of the present invention can easily and surely break the integrally assembled end plate at the peripheral end, and therefore crushes the cylindrical portion of the container flat. Waste collection process becomes extremely easy,
This processing is easily achieved at each site, does not require special large equipment such as a predetermined crusher, and does not pile up unprocessed waste cans, so that the occupied space can be minimized, It is easy to manage and transport waste, and it has many excellent effects, such as the score line groove for breakage maintaining sufficient strength so that it does not break unnecessarily during use. Play.
