Description

[Detailed description of the invention] This invention forms steps, rising parts, and a curved upper corner surface on the outer surface of a plastic container lid, and transfers a transfer film or hot stamp foil with a metallic feel to the area surrounded by these. This invention relates to a container lid that makes it possible to impart a metallic feel to the surface of the container lid by transferring layers.

Conventionally, in order to display a metallic appearance on the outer surface of a plastic container lid, the metal molded product itself formed using a metal press is adhesively fitted to the surface of the container lid, and the metal is applied to the surface of the container lid by vacuum deposition (dry plating). There have been methods such as vapor deposition of fine powder and methods of attaching metal to the surface of the container lid using plastic plating (wet plating), but the first method of bonding the metal molded product requires extremely high dimensions between the plastic container lid and the molded product. Accuracy is required, and since the two parts are only fixed by adhesive, there are defects such as the two parts separating and spinning when a strong torque is applied to the container lid. The third plastic plating method has drawbacks such as limitations on the plastic materials used, very complicated processing steps, and extremely high costs.

The container lid according to the present invention is a completely new technology that fundamentally improves the drawbacks of the conventional technology.In particular, it uses a transfer technology to create a transfer film or hot stamp foil with a metallic feel on the surface of the container lid. In addition to thermally transferring the transfer layer, it is possible to create a three-dimensional metal appearance as if a metal molded product has been fitted by providing steps or rising portions in the portion of the film or foil where the transfer layer is transferred. This relates to container lids.

To specifically explain one embodiment of the present invention with reference to the drawings, the first embodiment is as follows.
In the figures and FIG.
Q: A step 2 of approximately 5 m/m is provided, and the portion below the step 2 is configured to have a smaller diameter than the upper outer diameter.

In addition, the upper edges of the outer peripheries of bottle lids 1 and 5 have a thickness close to that of the metal ring.
．． 3 to Q, a rising part 3 of about 5 m/m is formed, and the upper end corner curved surface 6 of this rising part 3 is 0.1 to 1. An angle R about the size of OR is formed.

Next, 4 is a transfer layer of a transfer film or hot stamp foil having a metallic feel that is thermally transferred to the outer circumferential surface above the step 2 and the entire surface of the rising portion 3, and is a transfer layer using a heat transfer method using a rubber roll type transfer machine. Transfer adhesive is applied.

In the present invention, a transfer film or hot stamp foil transfer layer with a metallic feel is transferred onto the surface of the container lid using a thermal transfer method, so unlike conventional vapor deposition or plating methods, the transfer layer with a metallic feel can be transferred in a three-dimensional manner. It can be displayed visually, and it is also a conventional press metal molded product.

Unlike when bonding with adhesive, there is no risk of peeling, and extremely high molding precision is not required. Since it is transferred to the protruding part of the curved surface at the upper end, it is possible to create a three-dimensional appearance that looks like a metal molded product has been fitted, and the work process is extremely simple, and it can be mass-produced at low cost. Moreover, since a film or foil transfer layer is used, the metal coating on the curved upper end corner surface can be carried out very beautifully and smoothly.
