Abstract

PURPOSE:To make it possible to accurately put a transfer foil with a simplified putting means, by successively putting the transfer foil, while pressing a unit transfer portion of the transfer foil against a product in the order, the lower transfer surface, the stepped part surface and the upper transfer surface, through a transfer jig. CONSTITUTION:A transfer jig 6 is disposed such as to oppose a product, for example, a cap 1. A transfer foil 5 is positioned between the cap 1 and the jig 6. While the cap 1 and the jig 6 are being rotated relative to each other, a unit transfer portion of the transfer foil 5 is successively pressed by the jig 6 against the cap 1 in the order, a lower transfer surface 2a, a stepped part surface 4a and an upper transfer surface 3a. With this process being repeated, the transfer foil 5 is put to a predetermined portion on the peripheral surface of the cap 1. The transfer jig 6 is constituted by a transfer roll 6 molded from an elastic material, such as silicone rubber, the roll 6 having a press surface 7 which comes in resilient contact with the upper transfer surface 3a and a transfer collar part 8. The degree by which the transfer collar part 8 projects is set such as to be slightly greater than the height of the stepped part 4 and such that it is possible for the press surface 7 to be elastically deformed to such an extent that it can properly press the transfer foil 5 against the upper transfer surface 3a.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to (1) a synthetic resin product, a N77 method for transferring transfer foil to the product, and a transfer device therefor,
The purpose is to enable transfer foil to be transferred to a synthetic resin product having a stepped portion.

Synthetic resin products used for cosmetic container caps and the like are desired to have a high decorative effect, so metal transfer foil is transferred to the molded product or metal vapor-deposited is applied.

Decorations using transfer foil and metal vapor deposition are now indispensable processes for giving products a sophisticated appearance, but compared to transfer foil, metal vapor deposition is more uniform.

The process was complicated and time-consuming, such as poor gloss and the need to apply an undercoat to the surface of the product before vapor deposition.

On the other hand, with transfer foil, all you have to do is transfer the pre-formed foil to a predetermined location, so you can operate it from the front car, and you can get a product with a good-looking metallic feel. .

However, since the transfer foil has a structure in which a single layer of foil is connected together, if a stepped part with unevenness is formed on the transferred part of the product, the allowable amount of elongation and deformation of the foil will occur. There was a drawback that it could break, and for such -ah products, it was necessary to rely on vapor deposition means, and many dissatisfied points remained.

The present invention aims to solve the above-mentioned conventional drawbacks and inconveniences by creating a synthetic resin product with transfer foil adhesion strength.

This is related to a transfer device, in which a synthetic resin product is placed between an upper transfer surface and a lower transfer surface through a stepped portion having a relatively large height and width, and is applied to the lower transfer surface, the stepped portion surface, and the upper transfer surface. It has a structure in which a continuous sheet of transfer foil is transferred, and the transfer strength is
Unit transfer part of transfer foil.

The structure is such that the lower transfer surface, step surface, and upper transfer surface are pressed against each other to transfer the transfer sequentially from i, and the transfer device is used to transfer the peripheral surface of the transfer roll as a transfer jig placed facing the product to the upper transfer surface. The transfer surface is a suppression surface that presses the transfer foil, and the suppression surface is provided with a transfer flange portion having a protruding height that is slightly larger than the height and width of the stepped portion.

Embodiments of the present invention will be described below with reference to the drawings.

First, FIG. 1 shows a synthetic resin cap 1 as a synthetic resin product of the present invention.

This cap 1 has a structure in which a flange part 3 is provided around the outer periphery of the lower end of a cylindrical main body part 2, and between the 1 main body part 2 and the flange part 3 is a stepped part 4 which is a flange surface. One continuous transfer foil 5 is rolled over the entire circumference from the lower transfer surface 2ab to the step surface 4as to the upper transfer surface 3a, with the peripheral surface of the portion 2 as the lower transfer surface 2a and the peripheral surface of the collar portion 3 as the upper transfer surface 3a. It is worn.

The width of the stepped portion 4 is relatively large, and exceeds the allowable amount of elongation deformation of the transfer foil 5.

In this way, the upper transfer surface 3a and the lower transfer surface 21! The following methods can be considered as means for transferring a sheet of FeF transfer foil 5 to the cap 1, which is a synthetic resin product provided with I.

That is, in order to transfer transfer foil to a normally cylindrical product, the transfer jig 6 is placed facing the product, the transfer foil 5 is positioned between the product and the jig 6, and the transfer foil 5 is placed between the product and the jig 6. The transfer foil 5 is pressed onto the transfer surface of the product by the jig 6 without mutually rotating the jig 6. Here, the transfer portion of 50 units of transfer foil is transferred to the lower transfer surface which is the second circumferential surface of the main body part. 2as Step surface 4a of step section 4, upper transfer surface 3I which is the circumferential surface of collar section 3!
The transfer foil 5 is pressed onto a predetermined portion of the circumferential surface of the cap 10 by repeating this process.

As a mounting device that can use such vertical transfer means, a transfer jig placed facing each other with a continuous transfer foil 5 sandwiched between the transfer rolls formed of an elastic material such as silicone rubber, etc. 6 is a one-circumferential pressing surface 7 that comes into elastic contact with the upper transfer surface 3a of the product via the transfer foil 5, and a transfer flange 8 is installed on a part of the pressing surface 7 between the plate and the plate. .

The width of the protrusion of this eave Tr section 8 is slightly larger than the pitch width of the front first step section 4, so please show it more specifically.

The circumferential surface of the transfer flange 80 presses the transfer foil 5 against the lower transfer surface 2a, and when sufficient pressure is applied to transfer the transfer foil, it bulges due to side force and presses the transfer foil 5 against the step surface 4u. However, at the point when the transfer due to this suppression is reliably achieved, the suppression surface 7 is transferred to the transfer foil 5.
The protrusion height width is such that it can be elastically deformed to the extent that it can be pressed against the upper transfer surface 3a.

Now, as is clear from the above explanation, the synthetic resin product of the present invention has a structure in which an upper transfer surface 3a and a lower transfer surface 2a are provided via a step section 4, and the width of the step section 4 is Although the transfer foil 5 is thicker than the allowable elongation deformation, one sheet of the transfer foil 5 is transferred from the lower transfer surface 2a to the step surface 4a and the upper transfer surface 3a. Therefore, although the structure has the stepped portion 4, the transfer foil 5 is transferred, so the decorative effect is extremely high compared to metal vapor deposition, the desired metallic feel can be obtained, and colors and patterns can be freely selected. The operation is extremely easy since it is covered with a transfer foil 5.

Also, when applying the transfer foil 5, the transfer portion with claws of one sheet of transfer foil 5 is pressed against the lower transfer surface 2ab step 4h of the upper transfer surface 3a of one piece of barge, so the transfer foil 5 If wrinkles are formed on the 5, they will not come off, and the transfer, including the stepped portion 4, can be smoothly, reliably and beautifully transferred.

The apparatus for performing such transfer is provided with a suppressing surface 7 for pressing the upper transfer surface 3a on the peripheral surface of the transfer roller 6, and a transfer collar 8 is provided protrudingly on a part of this suppressing surface 7. The protruding height and width of this transfer flange portion 8 is slightly larger than the height and width of the stepped portion 4, and when one phase presses the transfer foil 5 against the lower transfer surface 2a, the transfer foil 5 bulges due to lateral force. Step side 4
Press a.

Since the temporary pressing surface 8 is configured to press the upper transfer surface 3a, the transfer foil 5 can be accurately and reliably transferred to the product by a transfer operation similar to the conventional method.

Therefore, according to the present invention, since the synthetic resin product having a stepped portion has a structure in which a single sheet of transfer foil is transferred to the surface including the stepped portion, the appearance is extremely excellent and the potency and transferability are excellent. The hat has a simple attachment means, can transfer accurately, and has a simple configuration of the first attachment device, and has many excellent functions and effects.
