Description

  The present invention relates to a relatively small board that can be used in general households among boards used as a written display or a bulletin board for display objects such as a blackboard or a whiteboard. It is related with the adhesive sheet | seat which has.

  Conventionally, in the display of written indications and display objects, as represented by the blackboard used in school education, etc., a large receiving member that also serves as a powder receiver that can be used for white ink and blackboard wiping has been installed below it Configurations are known.

On the other hand, in recent years, small white boards and small bulletin boards that can be written and erased using felt pens that use water-based or alcohol-based inks that can be used at home have become widespread. As the structure for attaching these boards to the adherend article, when the adherend article is a ferromagnetic article, a structure equipped with a magnetic adsorption function is known, and the adherend article is a ferromagnetic substance. In the case of other than articles, there are various configurations such as a configuration in which an adhesive layer having removability is formed on the back surface using a flexible sheet base material and attached by adhesion, and other configurations such as hanging and mounting. Attachment means are used.
There are many types of these small boards that do not have a receiving member. Particularly, for a board having a structure in which a flexible sheet base material is used and a releasable adhesive layer is formed on its back surface, However, only a type without a receiving member can be seen, but in other configurations, a configuration having a receiving member is also known.

  That is, Patent Document 1 discloses a rubber magnet whiteboard in which a thin plate-like synthetic resin is applied to the surface of a rubber magnet, a hanging metal fitting is provided on the upper part, and a pen tray is provided on the lower part.

  Patent Document 2 uses a writing body in which a synthetic resin film is bonded to a core material of cardboard or a synthetic resin foam, and two or more holes are provided in the vicinity of the central lower end thereof. The structure which inserts and attaches the both ends of the support piece for pen placement which consists of flat form is disclosed.

Japanese Utility Model Publication No. 62-107995 Japanese Utility Model Publication No. 63-33992

However, in the technique of Patent Document 1, a specific method for attaching the pen tray to the rubber magnet is not disclosed, and it is usually interpreted that the pen tray is attached by adhesion or the like. Since care must be taken to prevent the agent from sticking out, soiling, and the position of the pen tray being displaced, inconveniences in productivity are likely to occur.
In addition, it is possible to imagine a configuration in which the pen tray is attached to the rubber magnet by magnetic attraction, but in this case, the pen tray must be made of a ferromagnetic material such as a steel plate, In addition, there is a need for a process that does not cause sharp burrs and the like, and there is a technical problem that a sufficient magnetic attraction force must be ensured so that it does not move easily when it comes into contact with the pen tray.

  Moreover, in the technique of patent document 2, in order to insert the support piece for flat-plate-shaped pen holders in the form provided in the cursive body so that the flat plate surface may become vertical, it matches the upper end surface. If it is not a pen of the form to be placed, there is a disadvantage that it is difficult to place and easy to fall, and because the end surface of the support piece for pen placement is inserted against the writing body, if a load is applied to the support piece for pen placement The inconvenience in strength that the end face is likely to bite and be damaged is expected.

  And about the thing of the structure which formed the adhesive layer which has removability on the back surface using the flexible sheet | seat base material, there exists a background for which the structure which has a receiving member is desired.

  Therefore, in order to eliminate the disadvantages in the prior art, the present invention is easy to mount the receiving member, can be reliably placed on a pen, etc., and can secure a stable mounting strength. It is another object of the present invention to provide an adhesive sheet with a receiving member that is excellent in performance.

In order to solve the above-mentioned problems, the present invention has been conceived as a result of earnestly examining the use of the action of attaching a sheet to an adherend with an adhesive force without using the structure of the sheet with the receiving member attached from the beginning. Specifically, it is flexible and comprises a pressure-sensitive adhesive sheet having a pressure-sensitive adhesive functional layer that can be repeatedly attached to and detached from the adherend on the back surface, and a receiving member. This adhesive sheet is formed with a punched portion penetrating from the front surface to the back surface, and the receiving member has a horizontal or upward inclined surface or an accessory receiving portion having a substantially L shape and a vertical shape provided at the rear portion thereof. The upper retaining part, the lower retaining part, or the upper retaining part and the lower retaining part are formed, and the receiving member does not come out of the punched part of the adhesive sheet. ,and It is possible inserted and locked as downward movement of is blocked from its locked state, when allowed to adhere to the back of the self-adhesive sheet to the adherend article receiving member is lowered at the lower surface of the punching unit And the upper retaining portion, the lower retaining portion, or the upper retaining portion and the lower retaining portion formed therein are deformed flexibly by the flexible adhesive sheet. It was set as the adhesive sheet with a receiving member of the structure hold | maintained in the clamping state over the whole surface between to-be-adhered articles | goods.

By having such a configuration, since the receiving member is not attached to the adhesive sheet from the beginning, the product is good because it only packs the disassembled member as a product. Since it is only necessary to insert directly into the adhesive sheet, it can be easily performed.
When the adhesive sheet is attached to the article to be adhered with the adhesive sheet attached from the back of the adhesive sheet through the accessory receiving part of the punched part , the receiving member is prevented from descending, and the upper part is removed. The stopper, or the lower retaining part, or the upper retaining part and the lower retaining part enter between them, and the adhesive sheet is flexible, so that the entire surface is covered with the adhesive sheet. Since it is held in a sandwiched state between the articles to be worn, it is indirect but surely attached.

  The pressure-sensitive adhesive sheet can be implemented by forming on the surface a writing layer that can be written and erased with a felt pen using an aqueous and / or alcoholic ink.

The adhesive sheet may be formed with a ferromagnetic sheet layer in an intermediate layer between the front surface and the back surface.
With such a configuration, since a product having various magnets mounted on the board can be magnetically attracted, convenience is improved.

  And, in the accessory receiving part formed on the receiving member, a notch and / or a protrusion can be formed, and in this way, accessories such as rubber bands are also hooked, Convenience can be improved.

According to the present invention, although it has a simple configuration, it is possible to reliably place a pen or the like, and to finish a magnetic adsorption type board with a receiving member having a receiving member with a stable mounting strength.
Therefore, it can be finished as a product with high productivity and low production cost.
Further, since the receiving member is not directly fixed to the adhesive sheet, the adhesive sheet can be used in a simple form without the receiving member.

It is characterized in that it is sometimes completed as an article, and will be described in detail below with reference to examples.

FIG. 1 shows an outline of an embodiment of the present invention. FIG. 1 (a) is an exploded perspective view, and FIG. 1 (b) is an enlarged side view of an adhesive sheet described below.
That is, the adhesive sheet 1 with a receiving member is composed of an adhesive sheet 2 and a receiving member 3.
And in order to complete as an article | item, the to-be-adhered article W for making the adhesive sheet 1 with a receiving member adhere and attach becomes an indispensable member.

The pressure-sensitive adhesive sheet 2 in this example is made of a composite whiteboard using a flexible ferromagnetic sheet 6a as a substrate 6, and can be written with a felt pen using an aqueous or alcoholic ink. It can be wiped off.
The adhesive sheet 2 has a thickness of about 1 mm to 2 mm, a width of about 300 mm to 500 mm, and a height of about 200 mm to 400 mm, and a punching portion 4 for inserting a receiving member 3 to be described later near the lower end. Is formed in a penetrating state. The size of the punched portion 4 is preferably a minimum size that allows the receiving member 3 to be inserted and locked.

  The composition of the pressure-sensitive adhesive sheet 2 made of this composite whiteboard is generally formed by laminating and bonding a whiteboard film 7 with an adhesive or pressure-sensitive adhesive on a ferromagnetic sheet 6a as a base material 6. Under the magnetic sheet 6, the adhesive adsorption layer 5, which is an adhesive functional layer, with a non-woven fabric 5 a interposed, is laminated and a protective film 5 b is further laminated on the surface of the adhesive adsorption layer 5. It has become.

  Among them, the ferromagnetic sheet 6a has a thickness of 300 μm to 900 μm, and has a function as an adherend capable of magnetically attracting other articles such as a clip equipped with a magnet, as a base. A material obtained by kneading a ferromagnetic powder and a small amount of an organic polymer elastomer as a binder is formed into a sheet by rolling, extrusion, or compression molding.

The filling amount of the ferromagnetic powder is often about 60 vol%, and specific materials include various iron powders and alloy powders with iron (for example, sendust powder, stainless steel powder), iron trioxide. Examples thereof include powder.
Examples of the organic polymer elastomer include chlorinated polyethylene, ethylene / vinyl oxide copolymer, ethylene / propylene copolymer, nitrile rubber, and acrylic rubber.

There are various types of the whiteboard film 7. As an example, the whiteboard film base 7 a has a thickness of about 100 μm to 200 μm and is made of polypropylene resin, vinyl chloride resin, polyester resin, acrylic resin. A white plastic film containing a white pigment such as titanium white is used as the writing layer 7b on the surface thereof, which is transparent and has a thickness of about 1 μm to 10 μm, such as a UV-crosslinked acrylic / silicone type. It is done.
In order to improve writing property, erasability and antiglare property, spherical fine particles (average particle size of 2 μm to 10 μm) may be added here.

  The adhesion adsorbing layer 5 has an adhesion function that can be repeatedly attached to and detached from the adherend W. In this embodiment, the thickness is about 400 μm to 1000 μm, and it is generally a flexible acrylic resin. Adhesive layer is formed by applying an adhesive of the same material to the surface of a foam sheet that has a sucker structure on the surface and is a closed cell type made of urethane resin. And has a synergistic effect with the adhesive.

  The adhesive functional layer represented as the adhesive adsorbing layer 5 has conventionally been based on a self-adhesive type and an adhesive type, and has many adhesive technologies. As long as it has a pressure-sensitive adhesive function, it can be appropriately selected and implemented without being limited to the present embodiment.

The non-woven fabric 5a is for the purpose of preventing migration of components in the above-mentioned adhesive adsorbing layer 5 and improving interlayer adhesion, and has a thickness of about 200 μm to 500 μm. A coalescence or polyamide resin is used.
The protective film 5b is a release film that is intended to protect the adhesive adsorption layer 5 and peels off when the adhesive sheet 1 with a receiving member is actually used. The protective film 5b is made of polyethylene having a thickness of about 20 μm to 60 μm. Used.

The receiving member 3 is made of a synthetic resin such as ABS resin, and has a substantially concave cross section. Generally, the plate thickness is about 1 to 2 mm, the width is about 200 mm, the depth is about 40 mm, and the height on the front side is about. 16 mm and the height on the back side is about 21 mm.
However, the material of this member can be appropriately selected and used, including other synthetic resins.
The form is such that the accessory receiving portion 8 is formed from the bottom portion 8a to the front rising portion 8b, and the upper retaining portion 9 is vertically formed on the upper surface of the rear portion of the bottom portion 8a. It has become.

  Next, the procedure for completing the pressure sensitive adhesive sheet 1 having the above-described configuration will be described with reference to FIGS. 2 (a) to 2 (c) and FIGS. 3 (a) and 3 (b).

First, as shown in a cross-sectional view showing a state before the receiving member 3 is locked in FIG. 2A, the upper retaining portion 9 of the receiving member 3 is in a horizontal state as indicated by an imaginary line. The tip is inserted into the punched portion 4 of the adhesive sheet 2.
Next, as shown in the cross-sectional view showing the locking operation state of the receiving member 3 in FIG. 2B, the retaining portion 9 of the receiving member 3 is imaginary with respect to the punched portion 4 of the adhesive sheet 2. When it is inserted so as to rotate, the upper retaining portion 9 of the receiving member 3 finally comes into contact with the back surface of the adhesive sheet 2 and is placed on the lower surface 4a of the punched portion 4 Thus, the adhesive sheet 1 with the receiving member in the locked state is obtained.

  And as shown in the sectional view showing the state after the locking of the receiving member 3 in FIG. 2 (c), the back surface of the adhesive sheet 1 with the receiving member in which the receiving member 3 is locked to the adhesive sheet 2, Press against the adherend W as indicated by the arrow.

  If it does so, as shown in the perspective view showing the attachment state to the adherend article of Drawing 3 (a) and the partial expanded longitudinal section of Drawing 3 (b), of adhesive sheet 2 in adhesive sheet 1 with a receiving member The back surface is attached to the adherend W with an adhesive.

At this time, the receiving member 3 is prevented from descending by the lower surface 4a of the punched portion 4 of the adhesive sheet 2, and the upper retaining portion 9 of the receiving member 3 located on the back surface of the adhesive sheet 2 is 3 (a), and as shown in FIG. 3 (b), since the adhesive sheet 2 is flexible, the entire surface is pressed against the back surface of the adhesive sheet 2, and the adhesive sheet 2 And the adherend W are held in a sandwiched state.

  It should be noted that the receiving member can be implemented with various modifications.

4A and 4B show a first modified example of the receiving member. FIG. 4A is a perspective view, and FIG. 4B is a cross-sectional view virtually illustrating a state of attachment to the adherend W.
In the first modification, the receiving member 10 has an upper retaining portion 12 in the same form as in the embodiment, but the accessory receiving portion 11 corresponds to the bottom portion 8a of the receiving member 3 in the embodiment. And is formed in a state of being inclined upward (inclination angle Y in the drawing is approximately 22 degrees).
Even in such a form, the accessory can be placed, and can be preferably used when the accessory is frequently used.
In addition, the angle of the accessory receiving portion is preferably a horizontal or upwardly inclined surface of about 45 degrees due to its nature.

5A and 5B show a second modification of the receiving member, in which FIG. 5A is a perspective view, and FIG. 5B is a cross-sectional view virtually illustrating the state of attachment to the adherend W.
In the form of the receiving member 13 of the second modified example, the accessory receiving portion 14 is composed of a bottom portion 14a and a rising portion 14b as in the embodiment, but the retaining portion is the receiving member 3 in the embodiment. The lower retaining portion 15 is formed vertically downward, opposite to the direction in which the upper retaining portion 9 is formed , and the height thereof is the same as the rising portion 14 b of the accessory receiving portion 14. ing.
Therefore, it is point-symmetric with respect to the center of the cross section, and the accessory receiving portion 14 and the retaining portion 15 can be used without distinction.
Also in the second modification, the receiving member 13 is prevented from descending by the lower surface 4 a of the punched portion 4 formed on the adhesive sheet 2, and the lower retaining portion 15 is sandwiched by the adhesive sheet 2 over the entire surface. Held in a state.

6A and 6B show a third modification of the receiving member. FIG. 6A is a perspective view, and FIG. 6B is a cross-sectional view virtually illustrating the state of attachment to the article W. FIG.
The shape of the receiving member 16 of the third modified example is that the accessory receiving portion 17 is composed of a bottom portion 17a and a rising portion 17b as in the embodiment, but the retaining portion is a receiving member in the embodiment. 3 is different from the upper omission embodiment of the retaining portion 9, in the form of successive upper retaining portion 18a, the lower retaining portion 18b is also formed perpendicularly.
In this form, as shown in a cross-sectional view of the attachment state to the adherend in FIG. 6 (b), the upper retaining portion 18a and the lower retaining portion 18b are flexible adhesive sheets 2 and Since the attachment strength of the receiving member 16 is improved because it is sandwiched and held between the adherends W, it can be preferably used in applications where the load weight of the accessory is large.

Moreover, as shown in the perspective view showing the modified example 4 of the receiving member in FIG. 7A, the shape of the accessory receiving portion 20 of the receiving member 19 is changed in shape so that various accessories can be easily placed. Can be implemented.
That is, if a plurality of, for example, two notches 20a are provided, for example, an accessory such as a rubber band can be hooked on the remaining piece 20b between them, and conversely even if an upward protruding piece 20c is provided. Can be used.
Further, if the hole 20d is formed, a bar-shaped article such as a taper can be inserted and locked.
Furthermore, when the application is limited, for example, as in Modification 5 of the receiving member in FIG. 7B, the accessory receiving portion 20e of the receiving member 19a is formed with only a large number of upward protruding pieces 20f. You may make it do.

  In addition, although the receiving member demonstrated so far is a thing with comparatively large width dimension, if arrangement | positioning of pens etc. is possible, it is naturally possible to implement even if it is narrow width. .

  FIG. 8 shows an example thereof, and the receiving member 21 in FIG. 8A shows a modified example 6 in which the width of the receiving member 3 of the first embodiment is about ½, and FIG. The receiving member 22 shows a modified example 7 in which the width of the receiving member 10 of the modified example 1 is about 1/4.

The present invention can be implemented with various modifications.
For example, the adhesive sheet can be used for various bulletin boards as well as the use of the white board as in the above-described embodiments.
In this case, it is possible to use, for example, a felt member having good tactile sensation and appearance instead of the whiteboard film 7 of the pressure-sensitive adhesive sheet 2 in the embodiment.

  When the adhesive sheet does not require a function as a ferromagnetic material, a general-purpose synthetic resin that simply satisfies the function as the substrate 6 instead of the ferromagnetic sheet 6a of the adhesive sheet 2 in the embodiment. A sheet or a foamed resin sheet may be used, and depending on circumstances, the substrate 6 may be omitted.

  Furthermore, various modifications of the receiving member shown in the embodiments can be carried out by being modified to other forms.

Since the present invention has a simple configuration with respect to the adhesive sheet, the receiving member can be securely attached, and the receiving member can be easily removed, so that it can be selectively used depending on the purpose. Convenience is high.
In addition, as long as the board adheres, it can be applied not only to the white board but also to various bulletin boards.
Therefore, it can be used in a wide range of fields from general households to business use.
