Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a can body container with safety measures taken when opening the lid.

(Prior art) In the case of a so-called full-open type can, when the lid is torn along a score line carved in an annular shape around its periphery when the lid is opened, the cut piece after the lid is opened is There is a risk of injury to hands and fingers as they are sharp.

Therefore, we proposed a method of attaching a safety cap to the lid of such a can body and opening the lid through the safety cap to prevent the cut end of the cut piece from touching fingers when opening the lid. (Refer to Utility Model Publication No. 59-42346).

(Problem to be solved by the invention) However, although the above proposal effectively avoids the risk of injury to hands and fingers, the can itself does not have safety measures, so In addition, a safety cap is required, which increases the number of parts and increases costs.

The present invention was developed in view of the above problems, and its purpose is to provide a can body container that does not require any separate parts, has a simple structure, and is inexpensive, and can ensure safety by itself when opening the lid. is to provide.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a can body container which is formed by sealing the opening of the can body with a metal lid body, in which the outer surface of the lid body is made of resin. At the same time as covering the resin thick film, an annular main score line is carved on the inner surface of the lid covered with the resin thick film, and the resin thick film is cut along the outer periphery of the main score line. It is characterized by what it did.

(Function) Therefore, if the lid is torn along the main score line when the lid is opened, the cut portion of the thick resin film coated on the surface of the lid will be directed to the outside of the cut section of the cut piece after the lid is opened. Since the protrusion prevents fingers from touching the incision, safety is ensured when opening the lid. This safety measure is taken by the can body itself and does not require any separate parts, so safety is ensured when the lid is opened with a simple structure and at low cost.

(Example) An example of the present invention will be described below based on the accompanying drawings.

First, the overall structure of the can container will be explained based on the perspective view in FIG. 3 and the partially cutaway side view in FIG. The upper opening of the can body 1 is sealed by a metal lid 2, whose peripheral edge is wrapped around the upper edge of the body of the can body 1. It's tightened.

By the way, as shown in FIG. 1, the lid body 2 has the following features:
A thick resin film 3 made of polyethylene terephthalate P17 or the like is coated or adhered to the outer surface of the cover body 2, and an annular main score line 4 is formed on the peripheral edge of the inner surface of the lid body 2 covered with the thick resin film 3. is engraved. Further, the resin thick film 3 is cut concentrically with the main score line 4 along the outer periphery of the main score line 4 over its entire thickness. still,
The weight of the lid 2 and the resin thick film 3 is 0.1Kg.
It is bonded with a peel strength of f/mm width or less. Further, there are auxiliary score lines 5 on the outer surface of the lid body 2, which are formed when the thick resin film 3 is cut. The auxiliary score line 5 is not broken even when the lid is opened, which will be described later.

On the other hand, a pull ring 6 is provided on the lid 2 (more specifically, on the resin thick film 3) with its intermediate portion fixed by a rivet 7 that integrally projects from the lid 2. One end of the pull ring 6 constitutes a ring-shaped lifting part 6a, and the other end constitutes a pressing part 6b. Within the removed portion of 2,
Moreover, it is arranged at a position close to the main score line 4.

When opening the lid of the can, if you put your finger through the lifting part 6a of the pull ring 6 and trigger it, the pressing part 6b on the opposite side will move inside the main score line 4 using the rivet 7 as a fulcrum. The lid 2 is pressed downward to break the main score line 4 as shown in FIG.
Then, when the slightly raised lifting part 6a is further pulled up, the lid body 2 surrounded by the main score line 4
The removed portions 2a are sequentially raised while being fractured along the main score line 4, thus opening the lid of the can. In this process, the resin thick film 3 cut from the auxiliary score line 5 portion
As mentioned above, the adhesive strength (peel strength) between the lid 2 and the thick resin film 3 is 0.1 Kgf/mm at the peripheral edge of the portion 3a attached to the outer surface of the lid removed portion 2a.
Because it is smaller than the width, it peels off from the outer surface of the lid 2 as shown in Fig. 2 and protrudes outward from the cut portion of the lid removed portion 2a, making it difficult for fingers to touch the cut portion of the lid removed portion 2a when opening the lid. This ensures safety when opening the lid. This safety measure is taken by the can body itself and does not require any separate parts, so safety when opening the lid is ensured with a simple structure and at low cost.

In the above embodiment, the entire outer surface of the lid body 2 was coated with the resin thick film 3, but this resin thick film 3 was applied to the lid body in an area slightly larger in diameter than the annular main score line 4. The removed portion 2a region may be coated.

(Effects of the invention) As is clear from the above description, according to the invention, the outer surface of the metal lid body is coated with a thick resin film, and the thick resin film is spread along the outer periphery of the main score line. Since the lid was cut along the main score line when the lid was opened, the cut portion of the thick resin film coated on the surface of the lid would protrude outside the cut edge of the cut piece after the lid was opened. Since fingers are prevented from touching the cut, safety is ensured when opening the lid. In addition, this safety measure is taken by the can body itself and does not require any separate parts, so that the structure is simple and inexpensive, and safety is ensured when the lid is opened.
