Abstract

PROBLEM TO BE SOLVED: To provide a suction sheet and its manufacture, capable of reliably sucking even an article having a rugged surface by first allowing flexible suction pads made of a foamed resin, etc., to hold fast an article having a rugged surface, adjusting highly rigid non-foamed suction pads, each being provided inside the flexible suction pad, so as to be substantially parallel with the surface of the article to which the opening faces of the non-foamed suction pads are confronted, and further pressing the non-foamed suction pads against the article so as to strongly suck it. SOLUTION: This suction sheet has multiple suction pads 2 which are provided in a scatteredly clot-like manner on a base sheet 1 made of resin or rubber, and which are formed of resin or rubber in the same quality as that of resin or rubber forming the base sheet 1. Each of the multiple suction pads 2 has a suction pad 3 rising annularly by foaming and at least one non-foamed suction pad 4 rising annularly on the inner circumferential side of the suction pad 3, and the height of the foamed suction pad 3 is set to the highest level. The manufacture of the suction sheet includes a step of performing the screen process printing of the outermost suction pad on the base sheet with ink containing a foaming agent, a step of performing the screen process printing of the suction pad on the inner circumferential side, and a step of heating the base sheet after printing.

った。When the suction sheet is pressed against an article, the suction sheet absorbs the article by reducing the pressure inside the suction cup. For this purpose, the suction sheet is pressed before the suction sheet is pressed. The opening must be in close contact with the article surface over the entire circumference. However, when the surface of the article has undulations, each suction cup cannot follow the undulation and change its inclination due to the rigidity of the suction sheet itself, and the surface formed by the suction cup opening (hereinafter referred to as an opening surface) is formed. Since an angle is formed with respect to the surface of the article to be confronted, the suction opening does not adhere to the surface of the article over the entire circumference, and even if the suction sheet is pressed as it is, the suction sheet does not adsorb properly. For this reason, the above-mentioned adsorption sheet can be adsorbed substantially only on articles having a flat surface such as bulletin boards and window glasses.

A highly rigid non-foamed suction cup is made almost parallel to the surface of the article facing the opening surface, and it is pressed against the article to strongly adsorb it, so that even articles with uneven surfaces can be reliably absorbed. It is an object of the present invention to provide an adsorbable sheet and a method for manufacturing the same.

マーが含まれる。In order to solve the above-mentioned problems, the suction sheet according to the first aspect of the present invention is a suction cup which is formed on a resin or rubber base sheet by foaming with a resin or rubber of the same quality as the suction sheet and stands up in a ring shape. And at least one non-foamed suction cup which rises in an annular shape on the inner peripheral side of the suction cup, is provided in a scattered manner, and the height of the foam suction cup is set to be the highest. The rubber mentioned here includes a rubber mainly composed of natural rubber or synthetic rubber, and an elastomer.

する。When the suction sheet is pressed against the article, the opening of the flexible foam suction cup is brought into close contact with the surface of the article over the entire circumference, and the internal pressure is reduced, whereby the suction is performed on the article. As a result, the opening surface of the non-foamed suction cup inside it becomes substantially parallel to the surface of the article, and when it is pressed against the article, it adheres well to the article. In this case, the non-foamed suction cups have higher rigidity than the foamed suction cups, and thus strongly adsorb.

物が倒れることを防ぐことができる。As shown in FIG. 3, when the suction sheet constructed as described above is pressed against the article W, the opening 3a of the flexible foam suction cup 3 comes into close contact with the surface of the article over the entire circumference (the state of FIG. 3A). , The article W is reduced by reducing the internal pressure.
Adsorb to. This allows the non-foamed suction cup 4 inside
The opening surface 4b is substantially parallel to the surface of the article facing (state (b) in the figure), and when it is pressed against the article, it is well adsorbed to the article (state (c) in the figure). In this case, since the non-foamed suction cups 4 have higher rigidity than the foamed suction cups 3, they strongly adsorb. Therefore, the suction sheet can surely suction the article w having an uneven surface. In addition, what is necessary is just to change suitably the shape and arrangement | positioning of the said suction cups 3 and 4 according to a use. As an application of the suction sheet, for example, there is an insole for shoes. That is, for example, an adhesive is applied to the surface of the suction sheet opposite to the suction cup, the suction cup surface is placed on the shoe sole side, and the adhesive surface is placed on the insole side between the shoe sole and the insole. Things. In this way, the insole can be securely fixed to the shoe sole by sufficiently adsorbing the shoe sole having an uneven surface, and can be easily removed without a trace when unnecessary. In addition, it can be used for fixing an article on an article. That is, an adhesive is applied to the surface of the suction sheet opposite to the suction cup as described above,
If an article is stuck on the adhesive surface and the surface on the suction cup side is attracted to an article such as a table, the article can be prevented from falling down when subjected to vibration due to an earthquake or the like.

精度よく形成される。Further, according to the above-mentioned manufacturing method, since the suction cups 3 and 4 are formed on the base sheet 1 with the same quality ink, the suction cups 3 and 4 are well adapted to the base sheet 1. When the printed base sheet 1 is heated, the outer suction cups 3 foam. Then, since the suction cups 3 and 4 are formed by screen printing instead of embossing, the multiple suction cups 2 are formed accurately without overlapping.

い。The present invention is not limited by the above embodiment. In the above embodiment, the multiple suction cups 2 are constituted by one foam suction cup 3 and one non-foam suction cup 4 on the inner peripheral side, and the height of the foam suction cup 3 is set higher than that of the non-foam suction cup 4. However, in the present invention, the multiple suction cups may be constituted by one foam suction cup and two or more non-foam suction cups on the inner peripheral side. In this case, the height of the foam suction cup includes the non-foam suction cup. It is necessary to set the highest among all the suction cups. The two or more non-foaming suction cups on the inner peripheral side may be provided side by side inside the foaming suction cup, or another non-foaming suction cup may be provided inside one non-foaming suction cup. Further, in the manufacturing method, contrary to the above embodiment, first, a step of screen-printing the suction cup 4 on the inner peripheral side with a resin-based or rubber-based ink of the same quality as the base sheet 1 is performed. On the sheet 1, a step of screen-printing the outer suction cup 3 with an ink mixed with a foaming agent, which is a resin or rubber of the same quality as the base sheet 1, is performed, and the printed base sheet 1 is heated. The process may be performed.
