Description

[Detailed explanation of the invention] This invention not only seals the mouth of the can, but also enables the use of a sliding contact piece with an opening diameter, and after opening the can, it is possible to seal the can mouth by covering it with an outer lid. This is about cans.

Conventionally, a number of structures have been proposed for cans with sealed can mouths, and each has been put into practical use, but the present invention is a can with a sliding contact piece pre-strung, and the can is sealed with a partition plate before opening. After opening, it is configured to be sealed with an outer lid.

That is, to explain this invention with reference to an embodiment, the upper edge of the synthetic resin type sliding piece ring 2, the periphery of the transparent synthetic resin film 3 as a partition plate, and the metal ring 4 are attached to the mouth edge of the can body 1. Overlap the upper edges one after another and secure by winding.

Next, a peripheral U-shaped portion of the metal top plate 6 was fitted and fixed onto the upper edge 5a of the synthetic resin-type fitting ring 5 to form an outer lid 7, and the outer lid 7 was fitted onto the can opening. It is something.

During this fitting, the lower edge curved portion of the fitting ring of the outer cover (
(curved in an arcuate cross-section) is fitted so as to enclose the winding portion 8 of the can mouth, thereby ensuring the sealing of the can mouth.

The lower end edge of the metal ring 4 is wound to have a circular cross section, and the winding portion 4a is overhanging to the inner wall of the can in the shape of an inner flange, and the extent of the overhang is S゛It is the same.

The inner edge 2a of the ring 2 with sliding sections is provided with cuts 2b at regular intervals.

9 in the figure is a sliding contact piece. To open the can of the above embodiment, the transparent synthetic resin film 3 is cut along the winding portion 4a of the metal ring using a tool such as a knife.

In this way, the cut edge and the inner edge of the sliding section ring 2 are flush with S, and it is possible to protect the hand or fingers from the cut edge of the transparent synthetic resin film.

Furthermore, if the transparent synthetic resin film is removed, the sliding contact plate will be exposed, which can be used for cutting spoons.

In the above, the can opening is relatively thick and has increased rigidity, so that it can be reliably sealed when the outer lid is placed on the can mouth.

In the above embodiment, a transparent synthetic resin film was used as the partition plate, but aluminum foil or a small transparent film may also be used.

4 and 5 also show embodiments of this invention, and the difference from the previous embodiment is that the sliding section 9 of the ring 2 with sliding sections is provided below so as not to come into contact with the lower surface of the transparent synthetic resin film 3. , an annular scoring line (score) 10 is provided on the periphery of the upper surface (in some cases the lower surface or upper and lower surfaces) of the transparent synthetic resin film 3 , and a curved portion 4 on the lower edge of the metal ring 4
It is at the point where a is formed with an outer wrap.

The annular scoring line 10 is positioned directly below the winding portion 4a to protect the hand or fingers from the cut edge of the transparent synthetic resin film 3, as in the previous embodiment.

In this embodiment, a cutting tool such as a knife is not required when opening the can, and the transparent synthetic resin film 3 is broken along the annular score line 10 by applying downward pressure to the peripheral edge with a finger or the tip of a spoon. Can be opened.

Furthermore, since a gap is formed between the sliding piece 9 and the transparent synthetic resin film 3, it is possible to prevent the contents of the can (particularly powder) from accumulating on the upper surface of the sliding piece 9 before opening.
It is possible to prevent a decrease in the visual value of the product.

That is, according to this invention, since the periphery of the ring with a sliding section and the partition plate is interposed between the can rim and the metal ring, it becomes similar to an elastic backing when tightening, ensuring airtightness, It has various effects such as increasing the rigidity of the can lip, preventing deformation of the can mouth, and ensuring a tight fit with the outer lid.

Furthermore, since the outer lid is constructed by fixing a synthetic resin fitting ring to a metal top plate, it has both the characteristics of metal and the characteristics of synthetic resin, and has the effect of being able to be tightly fitted in and out without the need for screwing.
