Abstract

PURPOSE:To insure uniform application of a predetermined amount of adhesive and good bonding to the surface of an adherend, by using a punched-out adhesive holder. CONSTITUTION:An adhesive holding frame 3 punched out in a desired shape is attached to the back side of a hook A (adherend) with an adhesive layer 4. Then an adhesive 5 squeezed from a tube 6 is filled in the depressed area and smoothed with a spatula so that the adhesive in a volume corresponding to the area and thickness of the punched out portion 1 may be held on the back of hook A. To effect bonding, the adhesive holding frame 3 is stripped off by the tab 2 and hook A is pressed against a substrate (e.g. wall surface).

Description

DETAILED DESCRIPTION OF THE INVENTION This invention is an adhesive that applies an adhesive uniformly to the back side of an adhesive hook, etc. through a die-cut adhesive piece, holds it, and then peels off the adhesive piece and adheres it to the surface of the object to which it is applied. The present invention relates to a method for bonding members.

Generally, the adhesive applied to the back side of an adhesive member such as a hook that adheres to a mural is applied by a non-uniform coating company, and as a result, there are large variations in adhesive properties and performance. In addition, since the adhesive is applied by coating, the applied surface is not finished neatly, and the adhesive protrudes to the periphery of the surface, reducing the product value. Especially when the adhesive concentration is low, the adhesive may drip and run. There were drawbacks such as:

The method of bonding adhesive members according to the invention of Jin was made to solve the problems of the conventional method, and the bonding hook of an embodiment of the present invention will be described below.

Figures 1 and 2 show the state before applying adhesive to the back side of the pedestal of the adhesive hook A, and a die-cut part l of an arbitrary shape and a gripping protrusion 2 are attached to the back side of the pedestal. The provided die-cut adhesive piece 8 is releasably attached via the adhesive layer 4.

Next, the adhesive of the hook A is applied to the concave portion of the die-cut portion 1 of the adhesive piece 8 in the steps shown in FIGS. 3 to 6 and held therein. That is, in FIG. 3, the adhesive 6 is squeezed out from the adhesive tube 6 into the die cut part 1, and then as shown in FIG. Ru.

In order to adhere the hook A with the adhesive held in the cut-out part l of the adhesive piece 8 to a mural, etc., as shown in FIG. Peel it off from A. A layer of adhesive having an area and thickness corresponding to the die-cut portion 1 is uniformly formed on the back surface of the hook A, and the hook A is then attached to a wall surface, etc.

Although the shape of the die-cut portion 1 is rectangular in FIG. 2, it is also possible to use a plant-shaped die-cut portion 1 as shown in the sixth factor.

In addition, the gripping protrusion 2' of the adhesive piece 3 is also formed larger than the pedestal of the hook A, and the gripping protrusion 2' is formed around the periphery, as shown in Fig. 7H). The same holds true even if a protruding gripping piece l is formed.

In the above embodiment, the method of bonding hook A among the bonding members was described, but the point is that the method can be applied to bonding members other than hooks as long as they are bonding members.

(According to Party B's invention, the adhesive of the adhesive member is applied uniformly, so stable characteristics are obtained with little variation in performance, and there is no need to worry about stickiness of adhesive, dirt, etc. on the periphery of products such as hooks) In addition to increasing the commercial value without any blemishes, the coating surface is smooth, so adhesion is reliable.
