Abstract

(57) [Problem] To provide an adhesive tool which is easy to handle, can be applied with good controllability, and can realize a stable adhesive force after hot pressing. A stick body (3) made of a non-tacky and water-insoluble adhesive composition is exposed so that a tip end (31) thereof is exposed.
The grip is covered with a wrap film 2. Since the wrap film 2 is in close contact with the holding portion of the bonding tool 1, the physical and mechanical strength of the stick body 3 is improved. Since the adhesive composition molded into a stick shape is based on the first thermoplastic resin capable of forming a film by friction with an adherend, the tip of the stick body is covered on various adhesive surfaces. The adhesive can be applied with good controllability simply by rubbing the surface. In addition, since the applied adhesive contains resin particles having a high softening point, stable adhesive strength can be realized after hot pressing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive tool also called a stick glue, and is particularly preferably used for temporary fixing in a sewing process of clothing.

[0002]

2. Description of the Related Art There are various types of adhesives, and a typical one is constructed by filling a tube with fluid glue. In addition, a stick paste in which a lump of paste shaped into a stick is housed in a container having a circular cross section and a cap is attached is also put to practical use. For example, Japanese Examined Patent Publication No. 47-25448 discloses an adhesive tool in which an adhesive stick composed of a molding substrate material and an adhesive component is put in a container used as a stick-shaped lipstick.

On the other hand, what is called a hot melt adhesive is also known (for example, JP-A-64-26688, JP-A-5-239285 and JP-A-5-255135), but these are solid at room temperature. Is done. Then, when used, it is liquefied by heating or by frictional heat when rubbed against the surface of the adherend and applied to the surface of the adherend, and the applied adhesive is cooled and cured (solidified) to exert an adhesive force. To do. Alternatively, a solid adhesive containing a liquid such as a solvent is applied to the surface of the adherend by rubbing it on the surface of the adherend to fluidize it during use, and the adhesive is dried and solidified to increase the adhesive strength. It is something to demonstrate.

Further, as an adhesive which can be used for temporary fixing of interlining in the sewing process of clothing, it is disclosed in JP-A-6-32.
No. 331 discloses a mixture of wax and a binder resin having a softening point lower than that of wax. This adhesive is in the form of powder or paste and is used by applying it to a cloth. In the sewing process of clothing, a film-like or non-woven fabric hot-melt adhesive is used.
Bonding and fixing with a heat press is also performed.

[0005]

As described above, various kinds of adhesives have been proposed in the past. However, all of the adhesives (adhesives) have merits and demerits, and can be easily used and can be applied to a wide variety of adhesive surfaces. It was possible to apply the adhesive evenly, and none could achieve stable adhesion.

For example, it is difficult to handle an adhesive that is sticky or fluid before use, and a container (tube or cylindrical case) for that is also required. Also, when a film or non-woven hot melt adhesive is sandwiched between the cloths to be bonded and fixed by hot pressing, the time and effort required for cutting are great, and the adhesive film is misaligned after being placed on the cloth. There was a problem.

Therefore, an object of the present invention is to provide an adhesive tool which is easy to handle, can apply an adhesive agent to a wide variety of adhesive surfaces with good controllability, and can realize a stable adhesive force after hot pressing. And

[0008]

The adhesive according to the present invention comprises:
A stick body formed by molding a non-adhesive and non-water-soluble adhesive composition into a stick shape, and a grip portion between the tip end portion and the base end portion of the stick body so that at least the tip end portion of the stick body is exposed. The adhesive composition described above comprises a first thermoplastic resin and resin particles dispersed in the resin and having a second thermoplastic resin as a constituent component. The first thermoplastic resin is a thermoplastic resin capable of forming a film on the adherend by friction with the adherend, and the resin particles have a softening point higher than that of the first thermoplastic resin. It is characterized by being particles.

Since the adhesive of the present invention is made of a non-adhesive and non-water-soluble adhesive composition in the form of a stick, it is easy to handle, and the grip portion is so exposed that at least the tip of the stick body is exposed. Since it is covered with a wrap film, the adhesive can be easily applied while gripping the adhesive with a hand. In particular, since the wrap film is in close contact with the grip of the adhesive, it plays a role in improving the physical and mechanical strength of the stick body, and frictional heat is generated suitably when the tip of the stick rubs against the adherend. Allows you to apply as much pressure as you want. Further, since the adhesive composition molded in the shape of a stick is based on the first thermoplastic resin capable of forming a film by friction with the adherend, the tip portion of the stick body can be attached to a wide variety of adhesive surfaces. The adhesive can be applied with good controllability simply by rubbing the surface to be adhered. Moreover, since the applied adhesive contains resin particles having a high softening point, a stable adhesive force can be realized after hot pressing.

In the adhesive of the present invention, the stick main body may be in the shape of a cylinder or a prism, and its tip may be tapered. In this way, the adhesive having a desired spread and thickness can be applied to the adherend having a wide variety of shapes with the sensation of using a writing instrument such as a pencil or a paintbrush.

In the adhesive of the present invention, the wrap film may be formed with a plurality of weakened portions along the circumferential direction of the stick body. In this way, when the adhesive becomes short, the wrap film on the tip side can be peeled off from the weakened portion, and the tip portion of the stick body can be sufficiently exposed again for use.

In the adhesive of the present invention, the softening point of the first thermoplastic resin may be 40 to 130 ° C. In this way, the stick body will not soften when held by hand in the summer season, and
By rubbing the tip of the stick body against the adherend by hand, the adhesive can be easily applied to the adherend. On the other hand, the softening point of the resin particles is higher than the softening point of the first thermoplastic resin, and is preferably 50 to 150 ° C., for example.

In the adhesive of the present invention, the melt volume rate of the first thermoplastic resin is 10 to 100 cm ³ /
It may be characterized by being 10 minutes. Here, the melt volume rate is referred to as the melt flow rate in JIS, but if the melt volume rate becomes large, the melt flow rate becomes easy to flow, and therefore the adherend is easily applied to the adherend.

In the adhesive of the present invention, the first thermoplastic resin may be a thermoplastic resin containing solid wax. Here, the solid wax is synonymous with the solid wax, but may contain a mixture of the solid wax and polyethylene glycol.

In the adhesive of the present invention, the second thermoplastic resin is preferably at least one thermoplastic resin selected from the group consisting of a polyamide resin, a polyurethane resin, a polyester resin and an ethylene resin. The average particle size is preferably 1 to 200 μm.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION An adhesive according to an embodiment of the present invention will be described below with reference to the accompanying drawings. In the description of the drawings, the same elements will be denoted by the same reference symbols and redundant description will be omitted.

FIG. 1 is a perspective view of an adhesive tool 1 according to the embodiment,
FIG. 2 shows an adhesive 1 with a wrap film 2 and a stick body 3
FIG. 3 is a perspective view showing a state in which the tip of the adhesive 1 is rubbed against the cloth 4 which is an adherend, and FIG. 4 is a view in which the tip side portion of the wrap film 2 is peeled from the stick body 3. It is a perspective view of a state. As is clear from FIGS. 1 to 4, the adhesive of the present invention is similar to a crayon as a painting tool, and the idea of this crayon was applied to a temporary tacking adhesive for cloth in the sewing process of clothing, which was unexpected. It is characterized by the fact that it has achieved an exceptional action and effect.

As shown in FIGS. 1 and 2, the stick main body 3 molded in the shape of a stick having a circular cross section has a tapered tip portion 31, and the tip portion 31 is exposed so that the stick tip portion 31 is exposed. The grip between the base and the base end is covered with the wrap film 2. The width of the wrap film 2 is longer than the circumference of the stick body 3, and therefore, when the wrap film 2 is wrapped around the stick body 3, the ends of the wrap film 2 overlap each other with a certain width. Since the wrap film 2 is adhered to each other at this overlapping portion,
The wrap film 2 comes into close contact with the peripheral surface of the stick body 3. For this reason, the wrap film 2 plays a role of improving the physical and mechanical strength of the stick body 3, and even when a force is applied by a hand gripping when the stick tip portion 31 is rubbed against the adherend, the stick body 3 It is possible to apply a pressure to the extent that frictional heat is suitably generated (the extent to which the stick tip portion 31 is softened by frictional heat) without breaking.

The wrap film 2 has four weakened portions 21 along the circumferential direction of the stick body 3, as shown by the dotted lines in FIGS. The weakened portion 21 is a portion that is literally physically and mechanically weakened. Specifically, it is a perforation or a thin portion, and the opposite force is applied to both sides of the weakened portion 21. It is a part that can be broken by pulling it apart. As the material of the wrap film 2 which plays a role of improving the physical / mechanical strength of the stick body 3 and which can be torn on both sides of the weakened portion 21, for example, polyethylene, polyvinylidene chloride or the like is used. be able to.

FIG. 3 shows how the stick tip 31 of the adhesive 1 is rubbed against the adherend 4 to form the adhesive coating 5. Since the adhesive composition is molded in the shape of a stick, it can be easily handled like a writing instrument. Also,
Since the grasping portion is covered with the wrap film 2 so that the tip of the stick body 3 is exposed, the adhesive can be easily applied to the adherend 4 while grasping the adhesive tool 1 by hand.

As shown in FIG. 3, when the adhesive coating film 5 is formed on the cloth 4 to be adhered, the stick tip portion 31 of the stick body 3 is gradually worn away and the stick body 3 is shortened to expose the tip. The parts are getting smaller. In this case, since four weakened portions 21 are formed on the wrap film 2 along the circumferential direction of the stick body 3, the wrap film 2 is formed at the most weakened portion 21 as shown in FIG.
It is enough to tear off and peel off the tip side. This allows
Again, the tip portion 31 of the stick body 3 can be fully exposed for use.

Here, the adhesive composition constituting the stick body 3 is non-adhesive and water-insoluble, and comprises a base material made of a first thermoplastic resin having a low softening point,
Resin particles made of the second thermoplastic resin dispersed in the base material are included. The first thermoplastic resin is a thermoplastic resin capable of forming a film (adhesive coating film 5 in FIG. 3) on an adherend by friction with the adherend (for example, adherend fabric 4). A mixture of the above thermoplastic resins may be used. Further, the composition may be suitable as a hot melt adhesive by adding a tackifier or the like.

The softening point of the first thermoplastic resin is 40 to 1
The temperature is preferably 30 ° C., and if the temperature is equal to or higher than the human body temperature or the maximum summer temperature, the stick body does not soften even when it is gripped by hand in the summer season. Also, the softening point is 13
If the temperature is 0 ° C. or lower, it can be softened by frictional heat with the adherend 4, so that the tip portion 3 of the stick body 3 can be manually pressed.
The adhesive can be easily applied to the adherend by rubbing 1 onto the adherend. Therefore, the meaning of "capable of forming a film on the adherend" means that when the stick body 3 is rubbed against the adherend cloth at a predetermined pressure and a predetermined speed in a room temperature state (work environment), the adhesive film is applied to the cloth surface. Can be understood as what can be formed.

It is an important condition that the first thermoplastic resin is a non-adhesive thermoplastic resin. Non-adhesive means that it is not sticky to the touch, and the adhesive as in JP-A-8-134428 differs from the first thermoplastic resin in that it has such properties. For example, non-adhesive means that when a resin coating with a thickness of 10 μm is formed on high-quality paper, another high-quality paper is stacked on this, and a 1 kg roller is made to reciprocate once in an environment of 25 ° C, both are torn. It can be defined as peeling without peeling.

It is also an important condition that the first thermoplastic resin is a water-insoluble thermoplastic resin. Water-insoluble means
It is a property that cannot be dissolved in water literally, and in this respect
It is completely different from the adhesive of 7-25448. When it is water-soluble, it is essential to store it in some kind of container (case of lipstick container in the case of the above-mentioned publication), and it is impossible to use it in the form of the present invention.

A thermoplastic resin containing a solid wax (solid wax) is suitable as the first thermoplastic resin satisfying such conditions, but it contains a mixture of the solid wax and polyethylene glycol. At best, also, the melt volume rate is 10~100cm ^3/1
It is preferably 0 minutes. Here, the melt volume rate is called the melt flow rate in JIS,
The larger this value, the easier the flow, and thus the easier it is to apply the adhesive to the adherend.

On the other hand, with respect to the second thermoplastic resin constituting the resin particles, its softening point is higher than that of the first thermoplastic resin, and is preferably 50 to 150 ° C., for example. Such thermoplastic resins include, for example, polyamide resins, polyurethane resins, polyester resins and ethylene resins, and may be a mixture of a plurality of thermoplastic resins selected from the group consisting of these. While the resin particles are evenly dispersed in the adhesive coating film 5, it is necessary to suitably exhibit the adhesive force by hot pressing with an iron or the like. Therefore, the average particle size is preferably 1 to 200 μm, and more preferably Is 80 to 160 μm.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, the stick body 3 is not limited to a columnar shape, and may have a prismatic shape such as a hexagonal cross section. By tapering the tip of the stick body 3, it is possible to use a writing instrument such as a pencil or a paintbrush. An adhesive having a desired spread and thickness can be applied to a variety of shapes of adherends.

[0029]

As described above in detail, according to the present invention, not only the adhesive can be easily applied while gripping the adhesive with the hand, but also the wrap film improves the physical and mechanical strength of the stick body. Since it is made possible, it is possible to pressurize the frictional heat appropriately. Furthermore, the adhesive can be applied with good controllability simply by rubbing it on the surface to be adhered, and since the applied adhesive contains resin particles having a high softening point,
After hot pressing, there is an effect that a stable adhesive force can be realized.
