Description

[Detailed description of the invention] The present invention is an upper lid for canned goods, and more specifically, a spoon is interposed between the recess on the upper surface of the canned lid and a paper container with a photograph of the contents and a product name written on it. This invention relates to the upper lid of a can made of synthetic resin.

As an example of the above-mentioned conventional top lid, one is known in which a cylindrical portion for holding a paper carton and a spoon are integrally formed at the bottom using polyethylene.

The upper lid is formed at a high position on the inner periphery of the cylindrical portion where the spoon contacts the paper container in order to prevent the paper container from coming off the cylindrical portion and falling onto the top surface of the can when attached to the can. It is located.

However, this has the disadvantage that it is difficult to cut out the spoon because the spoon is in contact with the back of the paper container.

Other examples of conventional upper lids include those in which the cylindrical part and the spoon are integrally molded, in which the spoon is formed at the bottom of the cylindrical part and the paper carton is supported at the upper part of the inner periphery of the cylindrical part. This method has been proposed by the applicant as Japanese Patent Application No. 57053/1983.

This is because when this top lid is attached to a can, the part that connects the cylindrical part and the spoon is pressed off at the upper end of the can's lid tightening part, and as a result, the separated spoon is attached to the top lid and the can's lid. It will be left between it and the recess at the top of the tightening part.

Therefore, if you remove the top lid from the can in this state, it is easy to take out the spoon because it is not connected to the top lid or the top surface of the can, but the disadvantage is that if you remove the top lid in a hurry, the spoon will fall off the top of the can. There is.

The purpose of this invention is to solve the above-mentioned conventional problems, and its structural features include a protrusion for fastening the paper container on the inner periphery of a cylindrical part with an inner diameter approximately equal to the outer diameter of the lid-clamping part of a can. In the upper lid of a can made of synthetic resin, the spoon is integrally molded with the cylindrical part, and the spoon is formed integrally with the cylindrical part through cutting parts provided at at least two places between the cylindrical part and the scoop end and handle part of the spoon. , the above-mentioned cutting part is a first cutting part provided at a high position that will not be cut off by the upper end of the lid seaming part of the can when the top lid is placed on the can, and a second cutting part provided at a low position where it will be pushed off by the upper end of the lid seaming part of the can. It consists of two cutting parts.

Therefore, although the top lid according to the present invention is integrally molded as in the conventional case and is attached to the can in one step, when the top lid is removed from the can, the first cutting part is fixed to the cylindrical part, while the first cutting part is fixed to the cylindrical part. Two cuts are cut from the cylindrical part, so that one end of the spoon is separated from the paper carton, making it extremely easy to remove the spoon.

Furthermore, since the spoon is attached to the cylindrical portion at least in one place, the spoon will not fall out by mistake when the top lid is removed from the can.

Furthermore, the present invention can save the molding material of the top lid by providing a deformable expandable structure in at least one of the cut portions.

In other words, in order for a spoon to function as a spoon, it must have a certain cross-sectional area (thickness) or more and be rigid, but since the cylindrical part only holds the paper container, it is A small cross-sectional wall thickness is possible and desirable from the standpoint of saving material.

However, resin materials that are slowly cooled generally have a higher shrinkage rate than those that are rapidly cooled, and when this is done with the top lid of a conventional synthetic resin can, the spoon part that was slowly cooled becomes thinner. The spoon shrinks more than the cylindrical part, and the spoon separates from the cylindrical part after molding.

However, in the present invention, the elastic structure due to deformation between the spoon part and the cylindrical part absorbs the difference in shrinkage, so the cylindrical part can be made thinner and the top cover can save molding material.

Embodiments of the present invention will be described below based on the drawings.

The spoon 1 is connected to the cylindrical part 7 at two places, excluding the scoop part 3 and the handle part 5.

Inside the cylindrical portion 7, a paper retainer 9 is provided on a part of the inner periphery in order to prevent the paper container 13 pushed in from above in FIG. 2 from falling out.

A deformable telescopic structure 11 is provided between the spoon handle part 5 and the cylindrical part 7, while the space between the spoon scoop part 3 and the cylindrical part 7 is simply narrowed to make it easier to cut.

As shown in FIG. 2, the top lid of a can made of synthetic resin has the above structure. First, the paper container 13 is pushed into the top lid from above, and the paper container 13 comes into contact with the paper retainer 9 and is tightly held in the cylindrical portion 7. Retained.

Next, when the top lid with folding carton is attached to the canned lid closure part from above, the upper end 15 of the canned lid closure part presses down between the cylindrical part 7 and the spoon handle part 5, and on the other hand, The gap between the scoop part and the cylindrical part 7 remains uncut, and the handle part 5 side of the spoon becomes free and separates from the back surface of the paper container 13.

Since the present invention is constructed as described above, it is possible to provide a top lid for cans that is extremely easy to use and inexpensive.
