Description

[Detailed description of the invention] Industrial application field: The present invention relates to an improvement of a can lid that is attached to a can body.

Conventional technology: The design of the top surface of conventional can lids, i.e., the color, pattern, type of goods stored, trademark, name for gifts, etc., is expressed on the top surface of the can lid made of thin iron plate. These designs were either painted directly on the can lid or glued to the top of the can lid. The former method of expressing the design directly on the top surface of the can lid by printing etc. is expensive, and especially when forming a can lid with a name, the unit price is extremely expensive unless there is a large order. . In addition, when a sheet expressing the latter design is glued to the top surface of a can lid, the periphery of the sheet appears on the top surface of the can lid, which is not only unsightly, but also makes the surface easy to stain and requires a lot of work for gluing. However, it had drawbacks such as being unsuitable for mass production.

Problems to be solved by the invention: This invention can extremely easily reveal and change the design of the top surface of a can, and can be used not only for mass production but also for small can lids with a specific design. Even when mass-produced, we can provide can lids that are inexpensive and have a good appearance without the edge of the sheet showing the design appearing on the top surface of the can lid or becoming dirty and unsightly. The purpose is to provide

[Structure of the idea]

Means for solving the problem... In order to achieve the above-mentioned object, the present invention has a top plate with a rising edge formed on the periphery fitted to the inner surface of the side periphery of the vertically open cylindrical body near the upper edge. Place the decorative sheet on the top plate, place the transparent body above it, and roll it inward with the upper edge of the side circumference of the cylindrical body and the rising edge of the top plate overlapped. The can lid has a structure in which a rolled edge is formed by performing this process, and the decorative sheet and the transparent body are overlapped and the upper and lower parts near the periphery are clamped by the top plate and the rolled edge. be.

Example...Strip-shaped thin metal plate (aluminum plate,
A short cylindrical body with an open top and bottom and an arbitrary shape such as a circular planar shape, an elliptical shape, or a square shape is formed by joining both ends of a zinc-plated thin metal plate, etc. A top plate 12 having a shape and size that fits into the inner surface of the side peripheral portion 11 of the short cylindrical body and made of the same material or a different material as the short cylindrical body is formed, and the top plate 12 is formed on the periphery of the top plate 12. A rising edge 12a is formed along the inner surface of the side peripheral portion 11 of the short cylindrical body near the upper edge. As shown in FIG. 2, the rising edge 12 of the top plate 12
a is fitted into the inner surface of the side peripheral part 11 near the upper edge of the short cylindrical body, and the upper edge 11a of the side peripheral part 11 and the rising edge 12a of the top plate 12 are overlapped. On the top plate 12, on the inside of its rising edge, paper or other decorative sheet 13 on which a design such as a desired color, pattern, trademark, name, etc. has been applied by printing, photographing, or other means is layered, and then A transparent body 14 such as a transparent sheet or a transparent plate, which is preferably water resistant and has the same shape and size as the pattern sheet, is layered on top of the pattern sheet.
As shown in FIG. 3, the upper edge 1 of the side peripheral portion 11
1a and the rising edge 12a of the top plate 12 are rolled inward to form a rolled edge 15 above the periphery of the transparent body 14, and the decorative sheet 13 is supported on the bottom plate 12; The transparent body 14 is wrapped around the rolled edge 1
5. Clamp and press.

〔effect〕

In this invention, the desired color and design are expressed only on the decorative sheet by means such as printed photographs, and from the state shown in Fig. 2 to the formation of the rolled edge shown in Fig. 3, it is directly applied to the top surface of the can lid. Compared to expressing the design by means such as printing, it is cheaper and the expression of the design is faster and easier, and even when manufacturing a small number of can lids with special designs or names, the unit price is almost unchanged and the cost is low. In addition, the decorative sheet and the transparent plate are fixed to the top plate all at once by forming a rolled edge, which is not only suitable for mass production, but also the decorative sheet,
The peripheral edge of the transparent plate is hidden inside the rolled edge and does not appear when viewed from above the can lid, giving it a good appearance. Furthermore, when using a water-resistant material for the transparent plate,
It prevents staining due to water, and other stains can be removed by wiping, which has the effect of keeping it clean at all times.
