Abstract

(57) [Abstract] [PROBLEMS] To provide a stick-type adhesive that facilitates assembly and has a simple propulsion mechanism. The present invention provides a propulsion device that has a plunger that holds a stick-type adhesive and an outer cylinder that surrounds the stick-type adhesive, and that moves the stick-type adhesive up and down and at the same time acts as an operating member ( 1) is molded as one unit by injection molding together with the outer cylinder and the plunger. The propulsion actuating member (1) is designed in the shape of a band, is connected to the plunger plate on both sides, has a pressure plate (3) at the apex, and is arranged on both sides with the band-shaped propulsion member (1) at the apex. Forming a point of intersection between the side edges of the pressure shield and the stick-shaped adhesive fixing member of the plunger plate (O), which is designed in the form of bristles.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick type adhesive having a plunger type holding device for stick type adhesive.

[0002]

2. Description of the Related Art A rotary base portion formed as a fixed plate and a plunger or a cap having a rotary spindle for engaging a stick type adhesive holding device and a sticking device for drying and damaging the stick type adhesive are provided. In the manufacture of conventional stick-type adhesives of the popular type that are tightly fitted to the barrel so that they are not subject to crushing, there is difficulty in quick assembly before filling the stick-type adhesive.

The base part, which comprises the barrel, the holding device and the rotary spindle, is manufactured separately and then assembled. In this case, in assembly, the rotary spindle must rotate quickly and very accurately through the central cavity of the retaining device, which is pre-inserted in the barrel, while at the same time the barrel covers the outer rim of the base part. Lock it.

Due to the considerable forces involved, the number of damaged retainers and damaged and discarded rotary spindles is acceptable for commercial reasons, especially from the perspective of recycling discarded products. Can not.

Further, in the use of such a nested stick adhesive, the rotating spindle that engages the core of the stick adhesive reduces the volume of adhesive available due to the space required for said spindle. I know that.

Also, the advancing length of the stick-type adhesive is limited by the pitch of the spindle, that is,
The longer the consumer wishes to advance, the higher the number of revolutions required for this.

It is also desirable to separate the moving mechanism and the rotary motion transmitted to the double screw spindle.

Accordingly, it is an object of the present invention to solve the above-mentioned assembly problems and propulsion mechanism problems.

[0009]

The principle of the solution according to the invention is that the design of the band is such that it is fixed on both sides of the plunger plate and has pressure plates at the apex, at the apex of which a band-like propulsion member It is based on the idea of moving the stick-type adhesive up and down by means of a propulsion actuating member that forms an intersection with the side edges of the pressure shields arranged on both sides, with two guide rings and a sealing member in the circumferential direction of the plunger. And the plunger plate has a fixing member of an adhesive member in the form of bristles protruding laterally into the outer cylinder, and the band-shaped propulsion actuating member, the plunger having the bristles and the outer cylinder are injection molded. One unit is formed when forming.

In this case, the outer cylinder has a circular cross section or an elliptical cross section. The oval-shaped cross section has the advantage that the user can form narrow or wide adhesive strips by handling stick-type adhesives.

After injection molding injection from the injection molding machine, the plunger has a sprue connection whereby the plunger is firmly connected to the inside of the barrel. Very conveniently, these connections are four.

Moreover, at least two lower guide rings on the plunger rim are advantageous.

The lower open end of the barrel has a snap ring that fits into the fit-on cap to prevent the stick-type adhesive from drying out or being damaged.

[0014]

Embodiments of the present invention will be described below in detail with reference to the drawings.

With reference to FIGS. 1 to 4, band-shaped members (1) are connected to both sides of a plunger plate (O), and the plunger is externally attached to a lower rim thereof via a sprue joint (5). Forming a unit with a tube (10), the outer tube (10) having a snap ring (9).
There are also two guide rings (7) on the periphery of the plunger.
And the lower ring comprises two ventilation passages (8). The plunger plate (0) has an array of bristles (6), which array acts as a fixed part of the stick-type adhesive. Band-shaped member (1)
Has a pressure plate (3) at its apex, and the band (1) intersects with the side edges of the pressure plates (2) located on both sides at this apex. The sealing member (4) seals the plunger during use.

FIGS. 1 and 2 show that it is an injection-molded article as it is when removed from the mold. During filling (see FIG. 6), the sprue joint (5) is broken to form the ventilation passage (8).

In use, the consumer manually pushes on the pressure plate (3), which moves the plunger into the barrel and the stick-type adhesive in the direction of the open barrel end. When the shape of the band-shaped member (1) is an elliptical shape, it has an effect of preventing the stick-type adhesive from inclining along the longitudinal axis α of the ellipse. At the same time, the shape of the side edges of the pressure plate (2) prevents the plunger from tilting over the short axis of the ellipse of the stick adhesive. The guide ring (7) at the periphery of the plunger resists the canting of the plunger, as can be seen from FIG.

It is apparent from the last position reproduced in FIG. 8 that the side edges of the band-shaped propulsion member (1) and the pressure shield (2) fit snugly on the inner wall of the barrel.
As a result, the guidance of the stick-type adhesive is improved.
