Description

[Detailed Description of the Invention] This invention relates to a metal can whose purpose is to prevent the lower surface of the bottom plate of the can body from directly touching the floor or other mounting surface.

When conventionally known large metal cans (for example, 5-gallon cans) are filled with contents, the center of the bottom plate sags down as shown in Figure 6 due to the weight of the contents, so that the lower surface of the bottom plate touches the floor. It comes into sliding contact with a surface (for example, a concrete floor) and damages the surface coating of the floorboard, causing rust or perforation.

However, in this invention, the protective member is fixed to the lower surface of the bottom plate of the can body, so even if the contents are put into the can body and the bottom plate sags, the protective member will come into contact with the floor etc. The bottom plate is now protected and there is no longer any risk of damaging its surface or causing rust.

That is, to explain this invention with reference to an embodiment, a polyurethane foam plate 3 having a diameter of about 3 cm and a thickness of about 3 TIrIIt is adhered to the center of the lower surface of a bottom plate 2 of a can body 1 using a resin adhesive.

In the above, the foamed polyurethane plate 3 was used as the protective member, but synthetic resins other than polyurethane such as polypropylene, nylon, etc. may also be used as long as they have appropriate elasticity and wear resistance.

Further, as shown in Figure 1, the thickness of the protective member must be such that it does not protrude beyond the peripheral edge of the bottom plate when the contents are not put into the can.

In addition, the size of the protective member is such that when the contents are stored in the can body and the weight of the contents is applied to the bottom plate, the protective member supports the bottom plate from hanging down, and the bottom plate 2 and the floor Side 4
It is sufficient to prevent contact between the two.

In addition, when one can body is stacked on top of the other can body as shown in Figure 3, the protective member comes into contact with the mounting convex part of the hand lever 5 to prevent the metal parts from coming into contact with each other. It is.

An adhesive layer 6 is provided on one surface of the protective member in the above, and a release paper 7 is adhered to the upper surface of the adhesive layer 6, and after peeling off the release paper before use, the adhesive layer 6 can be easily fixed by pressing the adhesive layer 6 to the bottom plate. I can do it.

That is, according to this invention, since the protective member is fixed to the center of the bottom plate of the can body, even if the contents are stored inside the can body and the bottom plate sags, other objects (for example, a hand lever) can be placed on the bottom surface of the bottom plate. There is no risk of direct contact with the mounting part or the floor surface, damaging the part, causing rust, or perforation.

Furthermore, by fixing a protective member to the center of the bottom plate, the lower surface of the bottom plate can be effectively protected.

However, the protective member has a very low thickness and is easy to fix, and fixing the protective member does not affect the manufacturing cost of the can.

In addition, since the protective member can be automatically fixed when the bottom plate is formed, it can be easily incorporated into the manufacturing process line.
