Description

[Detailed description of the invention] [Industrial application field] This invention relates to the top-bottom structure of cans.

[Technical background]

The main purpose of the can top and bottom pads of this invention is to prevent the deformation and damage of the can filled with the contents of the product, and to provide a protective coating to ensure that the product remains intact. In the manufacturing and distribution stages of cans, in order to prevent cargo from falling due to sliding when stacked, the top and bottom ends of the cans, or in some cases, only the top or bottom ends are engaged, and the top and bottom pads are engaged. In order to prevent the can from slipping out of the can, the basic form was to tie a synthetic resin band from above, but if the top end of the can was covered with these top and bottom pads, the can itself Since even the provided embankment will be hidden, if the above-mentioned bands are tied to form a cross on both the top and bottom of the can, they will serve both as prevention of deviation of the top and bottom pads and as the embankment. This form seems to be the most commonly used.

[Conventional technology]

Conventional top and bottom pads are generally made of corrugated paper and have a shallow box shape that allows for close contact between the top and bottom ends of the can to be covered and engaged, or in some cases only the top end or bottom end. It had been.

[The problem that the idea aims to solve]

The cans that are to be protected with top and bottom pads are generally in the well-known cubic form, commonly known as oil cans or Itto (18) cans, with an embankment in the center of the top surface, and It is constructed with a lid and a spout for pouring out the contents in one corner.

In order to prevent these cans from being deformed and damaged during the distribution stage, as well as to prevent the contents from collapsing due to sliding during stacking, a shallow box-shaped covering material generally made of corrugated paper called the above-mentioned top and bottom cover was used. However, due to its shallow box-like shape as described above, there are many cases where it easily deviates when the can is moved, so a banding process has been carried out with the aim of preventing deviation. . In addition, due to the covering of these top and bottom pads, on the top of the can, the embankment attached to the can itself is also covered with this top and bottom pad, making it impossible to use the dike at the distribution stage where it is most utilized. And, to prevent this heaven and earth guess from leaving,
As a substitute for embankments, it is customary to tie bands made of synthetic resin together so that they form a cross at the top and bottom. If you just look at the cans, they look like nothing unusual, but the work that goes into finishing them is hard labor. These packaging methods require manual engagement of the top and bottom and strapping for each can, and although the weight varies depending on the contents of the can, the weight generally starts from a minimum of 10㎓, and generally 20〓 to 40〓, and the above-mentioned packaging would not be possible without lifting work, and even more so, the formation of the single can packaging due to the criss-cross embankment formation of the belt would end up being a manual process. However, it had the disadvantage that very few people could endure long hours of continuous work.

The biggest reason why these straps are required is that the top and bottom pads easily separate from the can.

This invention involves the development of a top-and-bottom structure that cannot be separated from the can unless it is broken once it is engaged with the can.This eliminates the need for strapping work, which was previously used as a levee. However, this is an attempt to utilize the embankment provided on the can itself for its original purpose.

First, this eliminates the strapping work that was previously used, reduces the process of unloading and unloading cans, allows the embankment provided on the can itself to be used during cargo handling, and eliminates the need for attaching top and bottom pads. The purpose of this is to simplify the structure and to create a complete connection that is difficult to separate unless the engaging top and bottom pads are destroyed at the final consumption stage.

[Means to solve the problem]

This invention, as a means to achieve the above object, is to cover the entire outer periphery of the upper plate, which is formed to have the same shape and area as the upper and lower end surfaces of the can to be coated, and to cover the upper and lower outer periphery of the body of the can. The connection is formed so that the edges that can be bonded and coated are endless, and at least the edges that face each other are folded inward from the lower edge of the entire edge so that the upper edge thereof forms the lower edge of the bonding protrusion that forms the can edge. It is provided with a locking part that can be locked.

In addition, in the top and bottom support constructed as described above, a hole for a bank is formed in the center of the upper plate from which the bank provided on the end face of the can can protrude.

[Effect]

This idea takes advantage of the elasticity of the material that makes up the top and bottom pads, mainly corrugated paper or a synthetic resin plate, and uses the same means of engagement as the previous top and bottom pads, but once the When press-fitted into the end of the can, the inner side of the upper side of the locking part, which is folded back from the lower side of the edge, is in close contact with the side surface of the can, and if a pull-out action is applied from the can to this top and bottom pad, a ratchet effect will occur. As a result, it engages with the lower edge of the joint protrusion that forms the corner between the side surface and the top surface of the can, and its separation from the can continues until the top and bottom pads are destroyed.

In addition, if a hole is drilled in the center of the upper plate of the top and bottom plate, the bank provided on the can itself can be exposed, allowing the can to be filled with contents and transported. This eliminates the need for manual labor throughout the entire process up to the creation of the figure, making automatic mechanization possible. Furthermore, although it is of course possible to use a top and bottom pad with the above-mentioned hand embankment holes in the bottom of the can, it is preferable to use a top and bottom pad without holes in order to avoid contact with foreign objects.

〔Example〕

Next, an embodiment of this invention will be described with reference to the drawings.
A processed board made of corrugated paper or synthetic resin, etc. is placed around the entire outer periphery of the upper plate 1, which is formed to have the same shape and area as , so that the edge 2 that can be bonded and coated to the upper and lower outer periphery of the body of the can 20 is endless. is made of a material and is folded back inward from at least the lower edge 3 of the opposing edge 2 or the entire edge 2, and its upper edge 4 can be locked to the lower edge of the joining protrusion forming the can edge 22. A locking part 5 is provided to mainly form a top and bottom pad A for the can bottom, and a bank 23 provided on the end surface 21 of the can 20 is made to protrude from the center of the top plate 1 of the top and bottom pad A for the can bottom. The top and bottom pads B for the top surface of the can are formed by making the holes 6 for the hand bank clear.

[Effect of idea]

This idea allows the top and bottom pads to be press-fitted only to the upper and lower end surfaces or the upper surface, which are the protection points of the can. Due to the return action of the force, the upper side engages with the lower side of the can rim, and it is difficult to break off the engagement relationship once engaged, not only by natural release but also by applying a release action. The connection is so complete that it cannot be reused and has to be dismantled by destruction, and therefore the banding that has traditionally been used to hold the top and bottom in place is no longer necessary, and the use of the band as an embankment is also a problem. In addition to making it possible to use the bank itself, the bank hole provided in the can itself was drilled to expose the bank, and also made direct mechanical loading and unloading possible.

These workers who are involved in the work of attaching the top and bottom pads and hanging the straps have to lift and unload heavy cans many times in order to package each can, and if this becomes a continuous day's work, it can lead to industrial accidents. Although it was natural that this would cause some back pain, mechanical loading and unloading was possible because the cans themselves were used as embankments during the movement of the cans during the manufacturing process, especially when lifting and unloading the cans. This has a great effect of freeing people from heavy manual labor.

Furthermore, even with the effective construction means as described above, there is no more complicated construction than the conventional product, and the tremendous effect described above is achieved simply by increasing the material at the locking part that is folded back inward. In addition, the non-use of conventionally used bands and the disposal of conventionally used bands were nothing but pollution, but the effects of non-use are significant.
