Description

[Detailed description of the invention] The present invention relates to an extrusion container for a liquid content, especially a content liquid such as a low-viscosity instant adhesive, and is intended to be safe and easy to handle. It is.

Conventionally, various structures have been used as extrusion containers for extruding liquid contents with low viscosity, but recently, instant adhesives in liquid form with low viscosity have been used in large quantities.

Various types of instant adhesive containers are used, but the most typical one is one in which the content is poured out by its own weight by simply pointing the spout downward. there were.

In this device, the amount of the liquid to be poured out is limited by the opening area of the spout, thereby preventing it from flowing out unnecessarily.

However, since the outflow amount is simply regulated by the value of the opening area of the spout, the liquid content continues to flow out as long as the spout remains facing downward.

For this reason, if the container is carelessly placed on its side on a desk, the liquid content may leak out, causing an extremely inconvenient situation. The speed of application is required, and the application operation requires a certain degree of familiarity.

Separately, the body of the container is molded to be relatively flexible, and when pouring out the liquid, the body is pressed strongly and deformed to pour out the liquid. Although this type has the advantage of being able to adjust the amount of liquid dispensed by adjusting the amount of pressure on the body, it has the disadvantage that the liquid may be poured out if the body is pressed against your will. .

For this reason, the above-mentioned container is generally housed in another container that does not deform, making handling extremely troublesome and making the overall structure of the container complicated.

The present invention was devised to eliminate the drawbacks of the conventional examples described above.The container body is molded from a hard material that does not easily deform. A bullet body formed of a material is tightly assembled, the bullet body is housed in a head body whose bottom is made of a hard material, and a pressing body is assembled in a slidable and lockable manner within the head body. Accordingly, the elastic body is configured to be able to be deformed by pressing from the outside.

An embodiment of the present invention will be described below with reference to the drawings.

The extruded container according to the present invention has an elastic body 17 having a hemispherical shell-shaped dome piece 19 at the base 6, which is the upper end of the container 1 whose bottom is made of a hard material, and is tightly packed in such a manner that the dome piece 19 protrudes upward. When assembled, a pressing force is applied to the dome piece 19 of this elastic body 17 to cause it to elastically deform, thereby reducing the internal volume of the container 1 and forming a spout 4 opened at the tapered tip 3 of the container 1. The dome piece 19 is configured to extrude and pour out the liquid content according to the amount of elastic deformation of the dome piece 19.

The container 1 has a body part 2 having an elongated cylindrical shape, and a distal end part 3 which is tapered and has a spout opening at the distal end thereof, and a base part 6 having a slightly larger diameter at the proximal end part. .

An elastic body 7 formed of a flexible elastic material and having a dome piece 19 in the shape of a hemispherical shell is tightly assembled to the base 6.

Various means can be considered for tightly assembling the bullet 17 to the container 1, but in the case of the illustrated embodiment, an assembly cylinder 18 that tightly fits into the base 6 is integrally provided, and this It has a structure in which a collar piece 20 is provided around the upper end of the outer peripheral surface of the assembled tube 18 and located on the upper end surface of the base 6.

The dome piece 19 of the bullet piece 17 is tightly assembled to the base 6 so that it protrudes upward, and the base 6 has a cylindrical head body surrounding the dome piece 19. 7 is fixedly assembled.

This head body 7 is desirably molded from a hard material like the container 1, and has a shape in which the main body is a cylinder 8 with the base 6 extended upwardly, and surrounds a dome piece 19.

In the illustrated embodiment, the head body 7 has a stepped portion 1 at the lower end of the cylinder body 8.
An assembling cylindrical part 9 with a large inner diameter is formed through the cylindrical part 9, and an undercut for assembling and holding the base 6 is formed on the inner peripheral surface of the assembling cylindrical part 9. The collar portion 20 of the bullet 17 located on the upper end surface is pressed and clamped by the stepped portion 10.

Further, a thread 11 is provided around the upper end of the inner peripheral surface of the head body 7, and a flange 12 is provided around the upper end facing inward.

A pressing body 13 is assembled in the internal space of the head body 7 above the dome piece 19 so as to be slidable up and down.

This pressing body 13 is a type of piece body, and its upper end is positioned to protrude upward from inside the head body 7, and by applying a pressing force with a fingertip to the upper end surface of the pressing body 13 that is positioned upwardly protruding. The dome piece 19 is elastically deformed.

In the illustrated embodiment, the pressing body 13 is a cylindrical main body 1.
From the lower end of the outer circumferential surface of the head body 7, a threaded tube 15 having a bottom-shaped screw thread to be threaded with the thread 11 on the outer circumferential surface and having a short cylindrical shape that slides into contact with the inner circumferential surface of the head body 7 is connected. A bulging piece 16 projecting downward from the lower end of 14 is integrally provided.

The screw tube 15 has a bottom diameter larger than that of the main body 14, so that the pressing body 13 cannot be pulled out from inside the head body 7 due to the screw tube 15 coming into contact with the flange 12. .

Moreover, as is clear from FIG. 2, the threaded tube 15 is
1, the pressing body 13 becomes unable to slide vertically with respect to the head body 7, so that even if an external pressing force is applied to the pressing body 13, the pressing body 13 elastically deforms the dome piece 19. become unable to do so.

A thread 5 is provided around the base of the outer peripheral surface of the tip 3 of the container 1, and a cap 21 is screwed onto the tip 3.

A frame piece 23 is provided protruding from the inner surface of the top plate of the cap, and when the cap 21 is assembled to the tip end 3, this frame piece 22 seals the spout 4.

Since the present invention has the above-described structure, when not in use, the cap 21 is screwed onto the container 1 to seal the spout 4, and the screw tube 15 is screwed onto the thread 11, as shown in FIG. The pressing body 13 is fixedly attached to the head body 7 by screwing together.

In this way, when not in use, the spout 4 is sealed and the pressing body 13 is immobile, so there is no possibility of any inconvenience such as unnecessary pouring out of the liquid content.

To change the state from this state to the state where the liquid content can be used,
The cap 21 is removed from the container 1, and the screwing between the screw tube 15 and the thread 7 is released.

In this state, the pressing body 13 can freely move up and down within the head body 7, but since the passage area of the spout 4 formed in the container 1 is sufficiently small, the content liquid will flow from the spout 4 in this state. There is no such thing as being poured out.

To pour out the liquid content, a pressing force is applied to the upper end of the pressing body 13 that protrudes from the head body 7 to the outside, and the pressing body 13 is moved downward against the elasticity of the dome piece 19 to release the dome piece 19. By elastically deforming the pressing body 13, the content liquid is poured out from the spout 4 in an amount corresponding to the amount of downward displacement of the pressing body 13 and used.

When the pressing force on the pressing body 13 is released, the pressing body 13 is pushed up by the elasticity of the dome piece 19 and returns to its original position.

As described above, in the push-out container according to the present invention, the container 1 is completely sealed when not in use, and the liquid content will not be poured out unless a pressing force is applied to the pressing body 13 when in use, so that unnecessary There is no leakage of the contents.

Further, since the content liquid can be poured out in an amount according to the amount of depression of the pressing body 13, the amount of content liquid poured out can be freely controlled, and the operation of applying the content liquid is made easier.

Furthermore, the pressing body 13 is assembled at the upper end, and the liquid content cannot be poured out unless the pressing body 13 is intentionally pressed, so that the liquid content may be poured out inadvertently. It can be used safely without any problems.

As is clear from the above explanation, the extruded container according to the present invention is completely sealed and cannot be poured out when not in use, and the liquid content will not be poured out unless a conscious pouring operation is performed, so it is safe to use. Furthermore, it has many excellent functions and effects, such as being able to freely control the amount of liquid to be dispensed, and the dispensing operation being extremely simple as only a pressing operation on the presser body 13 is required. It is.
