Description

The present invention relates to, for example, a card holder attached to the side surface of a container for storing a product and for inserting a card in which the type of the product in the container is described, and in particular, a card holder manufactured of vinyl chloride resin, olefin resin, or the like. The present invention relates to an adhesive card holder having a pouch shape composed of a base material corresponding to the back surface and an opening member corresponding to the front surface and having an adhesive layer on the back surface.

Card holders are used, for example, in fields such as assembly factories and delivery sites, where they are often applied to transport containers used to transport products or semi-finished products between processes and factories. In addition to the workpiece, a card containing information about the product to be transported is enclosed in the transport container. There are many types of card holders as holders for packing the power, and many are consumed. The transport container is made of plastic or metal, but its outer wall is often a smooth surface. Therefore, double-sided tape or glue is required to attach the card holder there. Attach a release paper to the double-sided tape or glue to improve convenience.

For example, the conventional card holder of this type shown in FIG. 4 of Patent Document 1 is formed in a bag shape by welding the left and right and lower edges of a vinyl chloride sheet to a vinyl chloride base material, for example. .. This card holder is attached to the outer surface of the container that houses the product with double-sided adhesive tape that is adhered to the back side of the base material, and a rectangular card that describes the type of product in the container is put in and out of the bag-shaped part. Will be done.

As another typical example, there is an example in which an adhesive layer is pre-glued on the back side of the base material, but the description thereof will be omitted.

The problems of the prior art that the card holder has are as shown below.

(1) In the case of a card insert in which double-sided adhesive tape is attached to the base material, it is strongly bonded to the adherend, but it becomes difficult to separate the card insert from the adherend when the card insert is replaced, and the adhesive remains. There is a risk that it will end up. Also, if double-sided tape is attached to the entire surface, the cost will increase.

(2) A place for inserting cards that have been glued to the base material in advance, the cost is low, and when exchanging cards for inserting cards, it is easy to separate them from the adherend such as a transport container, but the cards are repeatedly inserted. At the left and right contact points between the base material and the opening member shown in circles in FIG. 10, the base material and the base material are peeled off from the adherend and lifted from the adherend, and dust easily enters through the gap, weakening the adhesive force. , The card insertion is damaged, soiled, deformed, etc., which deteriorates the adhesive ability of the card insertion and shortens the life of the card insertion. When a card containing a QR code (registered trademark) or barcode is inserted into the card, there is a risk that it cannot be read due to stains. Such a floating phenomenon and a fouling phenomenon also occur when a double-sided tape having weak adhesive strength or low stability is used.

In order to solve the above problems (1) and (2) at once, the present inventor has a second adhesion to a part or a plurality of parts of a base material having a first adhesive layer, which has a different adhesive performance from the first adhesive layer. We have found that a plurality of adhesive performances can be realized on the back surface of the base material by providing the layer, and have reached the present invention.

That is, the present invention has a resin sheet-like base material having a front surface and a back surface, having a first adhesive layer on the back surface, and being detachably attached to an adherend by the first adhesive layer. A resin-made sheet-like opening member having a surface area smaller than the surface area of the base material and overlapping the surface area of the base material, and a peripheral portion of the opening member excluding the edge portion that serves as an entrance / exit of a card. A welding layer in which a portion corresponding to the peripheral edge portion of the base material is welded is provided, and the base material, an opening member, and a welding layer form a bag shape, and the first adhesive layer is the adherend of the adherend. is adhered to the surface, a card insertion for inserting the card, on the specific area of the first adhesive layer corresponding to the both ends of the doorway, horizontally or second adhesive pair so as to face vertically The layers are laminated, and the adhesive strength of the second adhesive layer is stronger than the adhesive strength of the first adhesive layer, and the width of the second adhesive layer is set larger than the width of the welding layer. It is a card holder to do.

The resin of the base material (4, 204, 304) and the opening member (5, 205, 305) may be either a soft resin or a hard resin.

As the first adhesive layer (2, 302), there are usually a case where a double-sided adhesive tape is used, and a case where an adhesive is glued to a base material in advance and a similar adhesive function is imparted.

The second adhesive layer (10, 310) is preferably a double-sided adhesive tape or a layer to which an adhesive is glued.

The first adhesive layer (2, 302) is preferably a layer in which a weakly adhesive adhesive is glued on the entire back surface of a soft or hard base material. The glue may be a rubber-based adhesive or an acrylic-based adhesive.

The base material (4, 204, 304) and the opening member (5, 205, 305) are preferably made of a soft vinyl chloride resin and an olefin resin, and preferably have a welding layer between the peripheral portion and the base material.

According to the present invention, by providing the second adhesive layer having strong adhesiveness in a specific region of the first adhesive layer having weak adhesiveness, it is possible to realize two or more different adhesive performances on the back surface of the base material (1). ) It is possible to facilitate the separation from the adherend when exchanging the card holder, and it has the effect of reducing the cost, and (2) preventing the base material from floating away from the adherend. However, it has the effect of preventing the intrusion of dust through the gap and prolonging the life of the card holder. Further, since (3) the second adhesive layer 10 is laminated on the first adhesive layer 2, there is an effect of increasing the degree of freedom in the dimensions of the card insertion or the second adhesive layer.

It is characterized by. Hereinafter, each element will be described in detail with reference to the drawings.

The first adhesive layer 2 is obtained by pre-gluing an adhesive material on the back surface of the base material 4.

As shown in FIG. 6, the transport container 3 is a quadrangular box with an opening at the top. The card holder 1 is attached to the area between the ribs on the side surface of the short side of the transport container 3.

The base material 4 and the opening member 5 are made of soft vinyl chloride, and the base material 4 in the corresponding portion is heated at high frequencies with respect to the three peripheral edges excluding the upper edge portion of the opening member 5 whose upper side portion is the entrance / exit 7. Alternatively, the welding layer 8 is formed by heat welding by ultrasonic heating or the like.

A edging member 5a having a two-layer structure having a hollow shape and a bag-shaped cross section is provided at an edge portion of the opening member 5 which serves as an entrance / exit 7. In the edging member 5a, the upper end portion of the opening member 5 is bent, and the overlapped edge portions are heat-welded.

The second adhesive layer 10 is a double-sided adhesive tape. Double-sided adhesive tape with polyester base is attached. The polyester base material is an example, and other base materials may be used. The width of the second adhesive layer 10 is set larger than the width of the welding layer 8. A pair is provided so that the second adhesive layer 10 faces left and right.

A release sheet 11 is attached to the upper surfaces of the first adhesive layer 2 and the second adhesive layer 10 provided on the back surface of the base material 4. When the card holder 1 is attached to the transport container 3, the release sheet 11 is peeled off from the first adhesive layer 2 and the second adhesive layer 10, and the card is provided by the adhesive strength of the first adhesive layer 2 and the second adhesive layer 10. The insert 1 is adhered to the transport container 3.

The card holder 1 is a rectangle having a length of 10 cm, a width of 21.5 cm, and a thickness of 1 mm. An example of the opening member 5 is a rectangle having a length of 7.5 cm, a width of 21.5 cm, and a thickness of 1 mm. The edging member 5a has a length of 8 mm and a width of 21.5 cm. A weakly adhesive first adhesive layer 2 is provided on the entire back surface. The second adhesive layer 10 is a strong adhesive layer stronger than the adhesive force of the first adhesive layer 2, and examples thereof include a width of 0.5 to 2 cm and a length of 2 cm to 10 cm.

The manufacturing method of the card holder 1 of the present embodiment will be described. Here, the base material 4 and the opening member 5 are made of the same material, for example, vinyl chloride.

(1) A roll-shaped original fabric is obtained by gluing a glue made of a rubber-based adhesive or an acrylic-based adhesive on the entire back surface of the base material 4 and attaching the release sheet 11. This raw fabric is cut to a predetermined size by a cutting device having a cutter.

(2) The opening member 5 is aligned with the surface of the original fabric by an alignment mechanism, and the opening member 5 is welded to the base material 4 with a high-frequency welder to form a welding layer 8. Examples of the material of the adhesive for gluing the raw fabric include rubber-based and acrylic-based adhesives.

(3) Both sides of the release sheet 11 are peeled off as shown in FIG. 3, and the double-sided adhesive tape is attached by aligning the edges in the vertical direction to form the second adhesive layer 10. The width of the welding layer 8 of the vinyl chloride resin and the double-sided adhesive tape is wider in the latter.

The strength of the peeling force between the glue and the double-sided adhesive tape and the position of the double-sided tape can be set as appropriate. The thickness of the second adhesive layer 10 is preferably thicker than the thickness of the first adhesive layer 2 which is a glue layer, but this is an example. The adhesive strength of the second adhesive layer 10 may be changed between the front and the back. The peeling test is a test item for the degree of difficulty in peeling, and it is possible to grasp the central portion of the card holder and measure it by the tensile strength of the wire. Regarding the test item of the degree of ease of peeling, a comparative test was conducted on 8-10 samples of an appropriate number by hanging a weight at the end of the card holder attached to the box and measuring the peeling time. It is possible.

(4) By returning the release sheet 11 to its original position and adhering the release sheet 11 to the first adhesive layer 2 and the second adhesive layer 10, the entire back surface of the card holder 1 is covered with the release sheet 11.

Next, the operation and effect of the card insertion 1 of the first embodiment will be described.

A second adhesive layer 10 which is a double-sided adhesive tape is partially attached and laminated on the surface of the first adhesive layer 2 which has been previously glued to the entire back surface of the base material 4, thereby forming the first adhesive layer 2. Apart from the weak adhesive performance, the strong adhesive performance by the second adhesive layer 10 is partially provided, and it is possible to secure a difference of two or more adhesive performances in one adhesive surface.

That is, the first adhesive layer 2 that has been glued in advance keeps the adhesion between the card holder 3 and the transport container 3 weak, and when the card holder 1 is replaced due to dirt or stain, the card holder 1 is removed from the transport container 3. It can be easily peeled off, does not interfere with the separation from the transport container 3, and can be ensured that the separation work is easy. In addition, by laminating the specific region, which is the weak point of the card holder 1, with the strongly adhesive second adhesive layer 10, the base material 4 is a transport container at the left and right contacts when the opening member 5 is repeatedly opened. It is possible to suppress the floating away from 3.

Since the degree of freedom in the dimensions of the card holder 1 can be secured and the degree of freedom in the strength of the adhesive performance can be ensured, it is possible to appropriately meet the needs of consumers. For example, since the second adhesive layer 10 is laminated on the first adhesive layer 2, there is an effect that it is not necessary to remove an extra adhesive margin.

Since the first adhesive layer 2 is provided by gluing a weakly adhesive adhesive on the back surface of the soft base material 4, it is not necessary to attach two or more sheets depending on the size as in the conventional double-sided tape. Simplifies.
