Description

[Detailed Description of the Invention] The present invention relates to a double-sided adhesive adhesive piece that is convenient to use.

Traditionally, needles were used to fix community chest feathers, etc. to clothing, but for safety reasons, a double-sided adhesive adhesive piece that was attached on one side to the base of the feather was used instead of the needle. It is practiced to adhere and fix on the other side of the

However, in this case, before the user attaches and fixes this to clothing, it is necessary to peel off the release paper that has been temporarily attached to the other pressure-sensitive adhesive surface of the adhesive piece. The peeling process was extremely troublesome and inconvenient, as it was difficult to remove the adhesive piece without digging a nail into the edge of the adhesive piece.

The present invention eliminates these conventional drawbacks and provides a double-sided adhesive adhesive piece that is convenient to use.
It consists of a structure in which release paper 1a, pressure-sensitive adhesive layer 2a, support base material 3, pressure-sensitive adhesive layer 2a', and release paper 1a' are sequentially laminated, and the surface layer is peeled off, leaving the release paper 1a as the base layer. A laminated part 4 for adhesion having a relatively large surface area with a cutting edge 4a from the paper 1a' to the lower pressure-sensitive adhesive layer 2a, and a laminated part 4 for adhesion having a relatively large area with a cutting edge 4a for cutting from the paper 1a' to the lower pressure-sensitive adhesive layer 2a, and a laminated part 4 for adhesion connected to the laminated part 4 for adhesion from the surface layer release paper 1a' to the base layer. A relatively small-area laminated portion 5 for a knob having a full-thickness cut periphery 5a up to the release paper 1a is formed, and a base layer is formed by leaving the surface layer release paper 1a' at the connecting portion of these laminated portions 4 and 5. release paper 1
A double-sided adhesive adhesive piece comprising a cutting line 6 from a to the upper pressure-sensitive adhesive layer 2a'.

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a general manufacturing example in which a large number of double-sided adhesive adhesive pieces (hereinafter referred to as adhesive pieces) P are formed into a strip-shaped laminated sheet material G by die-cutting, showing an example of the implementation of the present invention. , shows the state immediately after die-cutting is completed without removing the remaining punched portion 7, and the second
3 and 3 show an example of a general product having a series of adhesive strips P of the present invention from which the punching residue 7 has been removed, and in this state, the adhesive strips P are peeled off and used as described in detail below. Ru.

As shown in FIGS. 1 to 3, the adhesive strips P of the present invention are produced by cutting a band-shaped laminated sheet material G into a predetermined shape by die-cutting at predetermined intervals, and making a large number of them in series. Each will be explained below.

The strip-shaped laminated sheet material G includes a base layer of release paper 1a, a pressure-sensitive adhesive layer 2a, a support base material 3, and a pressure-sensitive adhesive layer 2.
It consists of a structure in which a' and a release paper 1d are sequentially laminated. The release papers 1a and 1a' are made by treating the surface of a base material such as paper or plastic film in advance with a release agent such as a silicone resin. Pressure sensitive adhesive layer 2a, 2
A' is formed by applying a common pressure-sensitive adhesive such as rubber-based or acrylic ester-based adhesive. The support base material 3 is made of any material such as paper, nonwoven fabric, woven fabric, plastic film, plastic foam sheet, or a laminate thereof, and is selected depending on its intended use. For example, for adherends with uneven surfaces such as feathers or clothing, it is convenient to use a soft material with a thin thickness of about 10 to 50 μm in consideration of flexibility. For example, an adhesive piece P having an appropriate size and shape is formed by die-cutting the strip-shaped laminated sheet material G as described below. That is, the release paper 1a as the base layer is added to the strip-shaped laminated sheet material G.
From the release paper 1a' on the surface layer to the pressure-sensitive adhesive layer 2a on the lower layer, cut according to a frame line that connects points A, B, and C into an arbitrary shape, for example, a large arc shape, and cut into a large circle. A laminated adhesive part 4 having a relatively large surface area and an arcuate cut periphery 4a is formed inside the arcuate cutting line, and at the same time, in connection with the laminated adhesive part 4, the release paper 1a' of the surface layer to the release paper of the base layer is formed. The entire layer up to 1a is cut along, for example, a small arc-shaped line connecting the point ADC, and a laminated portion 5 for a knob having a relatively small surface area and a small arc-shaped cut edge 5a is formed inside the small arc-shaped cut edge. Then, the base layer is peeled off along the line connecting points A and C at the joint between the large arc-shaped adhesive laminated part 4 and the small arc-shaped knob laminated part 5, leaving the release paper 1a' as the surface layer. Pressure sensitive adhesive layer 2 above paper 1a
A score line 6 is provided by cutting up to a' to obtain the adhesive piece P of the present invention. After such die-cutting is completed, as shown in the second figure, the remaining laminated portion 7 on the outside of each adhesive piece P is removed.
is removed, leaving behind the strip of release paper 1a as the base layer.

Note that the adhesive strip P of the present invention may have a peeling force of the release paper 1a' on the surface layer against the pressure-sensitive adhesive layer 2a' than the peeling force on the pressure-sensitive adhesive layer 2a of the release paper 1a on the base layer, if necessary. It may be configured to be larger.

Next, an example of use of the adhesive piece P of the present invention will be explained.

First, as shown in the fourth figure, when the release paper 1a of the base layer is bent downward on the side of the small arc-shaped knob laminated part 5 of the adhesive piece P of the present invention, the small arc-shaped knob laminated part 5 is bent. Since it separates from the release paper 1a of the base layer and floats up leaving a small semicircular separation hole 8 in its wake, the gripping laminated portion 5 can be easily held with the fingertips. Next, this knob laminated part 5
While holding it in place, pull the release paper 1a of the base layer further downward as shown by the arrow, or press the laminated part 5 for gripping.
When the laminate part 4 is pulled upward and forward, the laminated part 4 for sticking
is peeled off from the release paper 1a of the base layer, and is obtained in the hands of the user as a stickable adhesive piece P' with the lower pressure sensitive adhesive layer 2a exposed on the lower surface. FIG. 5 shows a series of strip-shaped sheets of the present invention after the adhesive strip P' has been peeled off. Therefore, as shown in FIG.
In the drawing, the exposed pressure-sensitive adhesive layer 2a is attached to the base h of the wing H to obtain a wing H for attachment and fixation.Next, in order to attach and fix this to clothing, this When the holding laminated part 5 protruding outward from the base h of the blade H is held and pulled upward as shown in FIG. The surface layer of the release paper 1a' is removed, and the surface of the upper pressure-sensitive adhesive layer 2a' on the lower surface is exposed, so that the feather can be attached to clothing and fixed on the exposed surface of the adhesive.

In this way, since the knob laminated portion 5 is ultimately discarded, it is preferable to form it into a small surface area as much as possible.

As in the above embodiment, when the tab laminated part 5 is formed into a protruding part smaller than the sticking laminated part 4, it is recognized at a glance as a so-called "knobs" and is convenient for use with the sticking piece P. However, the shape of the protrusion is not necessarily limited to such a shape, and as shown in FIG. It may be configured to have a simple shape with no step between it and the peripheral edge 4a of the wearable laminated portion 4.

Since the adhesive piece of the present invention is constructed as described above, when it is used, the tab laminated portion 5 can be easily protruded outwardly by bending, so that it can be easily held with a finger. The laminated part 4 for sticking can be peeled off from the release paper 1a of the base layer by holding this, and can be stuck to the surface to be adhered with the pressure sensitive adhesive layer 2a exposed on the lower surface thereof, and further, The laminated part 5 for the knob is removed and the laminated part 4 for sticking is removed.
It has the effect that the upper surface of the pressure sensitive adhesive layer 2a' can be exposed and fixed to the surface to be adhered.
