Description

[Detailed description of the invention]

[0001]

[Industrial application field] This invention is based on various memos, messages,
The present invention relates to a memo holder that can hold a slip or the like in a place that is easily visible such as on a desk or a wall.

[0002]

2. Description of the Related Art As memo holders, there are known a desk-mounted type in which needle-like projections capable of piercing a memo are erected, and a magnet type which presses and holds a memo against a metal surface by magnetic force.

[0003]

[Problems to be Solved by the Invention] The desk-mounted type in which the needle-like projections are erected may be injured to the human body. In addition, the type of pressing with a magnet can be used only on a metal surface, and has a drawback that an object to be fixed is limited, and when there are a large number of memos, there is a risk of falling off due to insufficient magnetic force.

Therefore, the purpose of this invention is to
An object of the present invention is to provide a memo holder which can be easily fixed to an appropriate place without danger and has a high memo holding ability.

[0005]

The memo holder of the present invention is characterized by using a non-staining soft polyurethane elastomer sheet having a persistently high tack at room temperature. In other words, instead of using ordinary adhesives and adhesives, it has a high adhesiveness, and it is possible to fix notes and the like even at the end face, and the sheet-like material was peeled off against this adhesive force In this case, the end surface of the sheet-shaped material is peeled off, or the adhesive material is found to be applicable to polyurethane elastomer as a binding agent that does not migrate to the end surface of the sheet-shaped material, and the present invention has been accomplished. .

That is, a polyurethane elastomer is
Its physical properties are extremely diverse, but among them, it has persistent high tackiness at room temperature, and if dust etc. adheres, it can be easily removed by wiping with water, which impairs tackiness It has been found that a non-staining, relatively flexible soft polyurethane elastomer that is not removed is most suitable as a fastening agent that can detachably attach a memo or the like to its end face.

When a memo holder is made of a non-staining soft polyurethane elastomer sheet having a persistently high adhesiveness at room temperature, it can be directly attached to an object of any material by utilizing the adhesive force on the back surface. The front side is used as a memo fixing surface. Polyurethane elastomer
On the surface of the mersheet, in the longitudinal and width directions
Countless projections are projected, and notes are inserted between these projections
In this way, the memo is fixed at the end face.

[0008] In addition to forming a memo holder with a polyurethane elastomer sheet alone, the sheet is used as a base sheet.
, And attached to a desired location with an adhesive or a pressure-sensitive adhesive adhered to the back surface of the sheet. Also, a case for installation on a desk may be provided, and the case may be stored with the upper surface protruding from the case, and may be closed when not in use.

When using a base sheet or a case and fixing with a pressure-sensitive adhesive on the back surface, the same polyurethane elastomer as the memo holder can be used.

[0010] At the time of molding the polyurethane elastomer sheet, the adhesion to the metal surface can be enhanced by adding a magnetic powder.

When a base sheet or a case is used, it can be made to adhere to a metal surface by containing a magnetic powder.

A polyurethane elastomer sheet having projections can be easily obtained by, for example, pouring a polyurethane elastomer stock solution into a silicone mold and molding. The adhesive strength of the polyurethane elastomer is desirably 450 g / cm or more at a 180-degree peeling force, 115 g / cm or more at a 90-degree peeling force, and the flexibility is preferably less than 10 degrees as the hardness.

The arrangement of the projections is desirably such that the end surfaces of the sheet-like material are in contact with each other as much as possible. If it protrudes innumerably, a favorable bonding state can be obtained. It is desired that the projection has a three-dimensional shape in which the base is thick and becomes thinner toward the tip.

[0014]

As described above, it has a persistent high tackiness at room temperature, and when dust adheres, it can be easily removed by wiping with water, and the tackiness is restored when dried. Memo holder made of a soft polyurethane elastomer sheet that is contaminated and relatively flexible
And countless protrusions in the longitudinal and width directions on the surface
In the case of a memo holder protruding, there is no danger and various kinds of memos can be held simply by crimping the end faces .
Moreover, unlike normal adhesives and adhesives,
It can be easily removed as needed, and the adhesive does not move to the memo side.

[0015] When configured with the polyurethane elastomer sheet itself, it can be fastened to various objects as such in the back surface.

If the magnetic powder is contained in a polyurethane elastomer sheet or a base sheet to which this sheet is adhered, the fastening force to a metal surface is increased.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the accompanying drawings will be described below. Figure 1 is a sectional view showing an embodiment of a note holder according to this invention, the polyurethane elastomer sheet 1
Innumerable projections 2 are formed on the surface and installed on a desk etc.
In this case, note 3 is attached to the end face.
You.

This polyurethane elastomer sheet 1
Is obtained by pouring and molding a polyurethane elastomer stock solution into a silicone mold.
Degree of peel strength is 450 g / cm or more, 90 degree peel force is 115 g
/ Cm and a hardness of less than 10 degrees.

The arrangement of the projections 2 is desirably such that the end faces of the memos are as easy as possible to contact each other. However, in the arrangement in the longitudinal direction of the sheet, a slight deflection in the sheet width direction is provided between projections adjacent to each other. A preferable bonding state can be obtained. The reason why the projection is formed into a substantially truncated pyramid three-dimensional shape is to prevent the projection end from falling down as much as possible, and various other three-dimensional shapes such as a truncated cone can be adopted.

The polyurethane elastomer used has different tackiness depending on the blending ratio of various polyols and isocyanates. In any case, unlike the usual blending system of polyurethane elastomer, the desired preferred tacky adhesive is used in a reaction system containing too many polyols. The components and compounding ratios that provide the properties are adopted. In the selection, of course, components that are not likely to cause paper stains, transparency,
Selection is made in consideration of factors such as non-yellowing and durability. Also,
In molding the polyurethane elastomer, a curing agent and a cross-linking agent may be used in combination to promote the reaction, and any of a one-shot method and a prepolymer method can be employed.

[0021]

[Effect of the invention] As is clear from the above detailed description,
The memo holder of this invention has various types of memos, slips, messages, etc. on a polyurethane elastomer sheet with protrusions.
It can be fixed simply by crimping on the surface, and it can be easily removed by pulling as needed, so that it can be used safely for a long period of time.

Regardless of the installation place, such as on a desk or a wall, it can be appropriately installed at a desired place, and an optimum object as a memo holder can be provided.
