Abstract

PROBLEM TO BE SOLVED: To facilitate handling for transportation, storage and use and not to discharge waste by packaging a self-adhesive substance such as hot-melt adhesines, adhesives, adhesive binders and sealing agents into a sausage-like cylindrical article by using a plastic film. SOLUTION: A self-adhesive substance consisting of a synthetic resin, a synthetic rubber, a plasticizer, a petroleum substance, a natural resin, a filler, etc., is externally wrapped with an externally wrapping body 4 of a cylindrical plastic film and both ends are bound or heat-sealed with a plastic string 7 to package it into a sausage-like cylindrical article 8 with a diameter of 1-5cm and a length of 2-20cm. As handling and carrying of it becomes convenient and safe thereby and in addition, it can be fed into a dissolving tank as it is, handling becomes easy and there exists no possibility of discharging waste as a packaging container.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot-melt pressure-sensitive adhesive, an adhesive, which has recently been widely used.
The present invention relates to packaging forms such as adhesive binders and sealants.

[0002]

2. Description of the Related Art Conventionally, hot-melt adhesives (eg, paper adhesive tapes), hot-melt adhesives (eg, paper diaper adhesives), hot-melt sealants (eg, glass sealing agents), adhesive binders (eg, hillers). Items such as solidifying agents and paving agents that have a slight adhesiveness on the product surface use paper containers, plastic containers that have undergone mold release treatment such as silicon, aluminum containers and plastic multilayer films. Handling at the time of use is troublesome,
Moreover, the waste of the container remains afterwards.

[0003]

When used in large quantities, dowels, drums and the like are also used, but recently there is a problem in processing these waste cans. In addition, the above handling requires a special heating and sucking device, which requires not only equipment cost and running cost, but also requires space and labor for handling. Incidentally, conventionally, an anti-adhesive agent is often applied to the finished product situation in order to prevent this surface adhesion. The anti-adhesive agent is, for example, calcium carbonate, wax emulsion,
Silicon or the like. By the way, in the method as described above, there is a possibility that the parts other than the anti-adhesive surface are exposed and blocked due to the temperature change during transportation or inventory, or due to the deformation or flow of the product due to the weight due to the stacking. The present invention is intended to solve the above problems.

DISCLOSURE OF THE INVENTION The present invention is a sausage-shaped tubular body in which an adhesive substance made of synthetic resin, synthetic rubber, plasticizer, petroleum-based substance, natural resin, filler, etc. is wrapped in a tubular plastic film. Characterized by filling the product, the sausage-shaped tubular product has a diameter of 1 cm to 5 cm and a length of 2 cm to 20 cm. Both ends can be closed with plastic strings or heat sealed. .

1 is a schematic view of a filling apparatus for externally filling a sausage-like tubular article with an adhesive substance.
Is a hopper, 2 is an extrusion cylinder, 3 is a nozzle, 4 is an outer envelope, 5 is a binding device, and 6 is a cutting device. In the present invention, a synthetic rubber, a synthetic resin, a plasticizer, a petroleum-based substance, a natural resin, a filler, etc. (adhesive, pressure sensitive adhesive, sealant) or the like made by blending or reacting is put into the hopper 1, and the extrusion cylinder It is extruded from the body 2 through the nozzle 3, and the outer periphery of the body 2 is covered with a plastic film outer casing 4.

Plastic films include polyethylene, polypropylene, ethylene vinyl acetate copolymer, nylon, polystyrene, polyester, and other thermoplastics.
A film made of thermoplastic rubber or the like, which has a predetermined diameter of 1 cm to 5 c by an inflation film extrusion device in advance.
The cylindrical film of m is attached and stored on the outer periphery of the nozzle 3 in a covered state, and is pulled out together with the extrusion of the adhesive substance.

The binding device 5 is designed to bind the adhesive substance whose outer periphery is covered with a plastic film so as to bind the adhesive substance at a length interval of 2 cm to 20 cm. In this case, the binding cord material 7 is a plastic film. The same material is used.

The cutting device 6 is for cutting the above-mentioned bundled intermediate part, whereby the sticky substance is made into a sausage-shaped cylindrical product 8. FIG. 2 is a perspective view of the product. FIG. 3 shows another embodiment of the present invention. In the above embodiment, the front and rear ends of the tubular product 8 are bound by the string 7 made of the same material as the outer package 4, but in the present embodiment, it is not bound. Simply consolidating in a constricted state, that is, using a thermoplastic synthetic resin film for the outer package 4 and heating the film with an adhesive at a suitable interval while partially reversing and twisting it with a reversing machine (not shown). The eggplant is cut into pieces, and then cut with a cutting machine while cooling.

In the present invention, the filling device may be a plastic extruder, a multi-ruder, a ham sausage making machine, a stuffing machine or the like, or a high viscosity pump such as a snake pump or a gear pump. . For those without a heating device, the softening point of the mixed product is heated, and for those with a high viscosity, the viscosity is lowered to the extrusion capacity of the extruder. Although it depends on the viscosity of the mixed product at the time of injection, the temperature condition is preferably 50 ° C to 80 ° C.

In the present invention, when the viscosity of the sticky substance injected in the front and rear end sealing work of the sausage-shaped tubular product is relatively high or the temperature dependence is low, the above examples are not required. However, it is also possible to carry out cutting by simply using a constriction plate while partially heating.

[0011]

The present invention is carried out as described above,
The sticky substance made into a sausage-like tubular body is a sausage-like one having a diameter of 1 cm to 5 cm and a length of 2 cm to 20 cm, which is easy to handle. It enables simple transportation. In addition to enabling timely inventory management, temperature resistance and weight resistance can be added to improve blocking resistance. The product according to the method of the present invention is easy to handle because it can be directly loaded into the dissolution tank in addition to the above-mentioned handling and transportation convenience and safety, and is extremely useful in that it does not generate waste as a general packaging container. It provides an excellent packaging form.
