Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fluid extrusion container that can extrude contents without waste.

[What conventional techniques and inventions have tried to solve Problems to be solved〕

In a fluid extrusion container with elastic folds formed on the outer periphery, that is, a bellows-type container, no matter how closely the elastic folds are compressed, as long as it has the minimum width in the compressed state, the contents will remain and the entire contents will not be able to be extruded. First, the container had to be thrown away with its contents intact, so the remaining amount was wasted.

The present inventor has developed a fluid extrusion container that can extrude all of the wasteful contents.

[Means for solving problems]

The configuration will be described in detail with reference to the accompanying drawings as follows.

A convex portion 3 having a diameter that fits inside the elastic folds 1 is formed on the inside of the bottom of the extruded container 2 which has elastic folds 1 formed on the outer periphery,
The length of the protrusion 3 is such that when the elastic pleats 1 are compressed, the tip of the protrusion 3 reaches near the discharge port 4 of the extrusion container 2.

Further, an engaging portion 6 is formed on both the tip of the protruding portion 3 and the tip of the extruded container 2 to engage with each other.

Further, a flexible deformable cylindrical part 5 that can be inserted into the extruded container 2 by pressing the bottom part is connected to the rear part of the extruded container 2 having elastic folds 1 formed on the outer periphery, and the length of this deformable cylindrical part 5 is is characterized in that it is formed in such a length that the tip of the deformable cylindrical portion 5 reaches near the discharge port 4 of the extrusion container 2 when the elastic pleats 1 are compressed.

Further, an engaging portion 6 is formed on both the tip of the deformable cylinder portion 5 and the tip of the extruded container 2 to engage with each other.

[For production]

For example, when the tip of the extrusion container 2 is brought into contact with a crack in a concrete building, the expansion folds 1 are expanded and contracted, and the adhesive inside the extrusion container 2 is extruded and filled into the crack to repair the crack. - As shown in Figure 4, when the extrusion container 2 is compressed at the end of the extrusion work, the protrusion 3 or the tip of the deformable cylinder 5 on the inside of the bottom of the extrusion container 2 is near the discharge port 4. , it is possible to ensure that almost all of the adhesive in the extrusion container 2 is extruded.

At this time, the distal end of the protruding portion 3 and the distal end of the extruded container 2 or the deformed cylinder section 5, and the engaging portions 6 formed on both the distal end of the extruded container 2 and the distal end of the extruded container 2 engage with each other and extrude. Since the compressed state of the elastic folds 1 of the container 2 is maintained, the adhesive inside the extruded container 2 is surely extruded without remaining inside the extruded container 2.

〔Example〕

1 and 3 show a case where the extrusion container 2 is set in an extruder and the extruder is operated to push the suppressor 7 forward and press the bottom of the extrusion container 2. It is also possible to press by hand without using the body 7.

〔Effect of the invention〕

As described above, in the present invention, a convex portion having a diameter that fits inside the elastic folds is formed on the inside of the bottom of the extruded container having elastic folds formed on the outer periphery, so that when the bottom of the extruded container is pressed, the elastic folds gradually contract. The entire length of the extrusion container shrinks and the contents are extruded from the discharge port, but at this time, the bottom of the extrusion container has a protruding part with a diameter that fits inside the elastic folds, so as the elastic folds contract, the contents will be pushed out. The exit part will also move forward into the inside of the contracting elastic folds, and the length of this protruding part should be set so that when the elastic folds are compressed, the tip of the protruding part reaches near the outlet of the extrusion container. Therefore, at the end of the extrusion operation, the tip of the convex portion advances close to the discharge port, and almost all of the contents are extruded without leaving anything behind.

This is the same when a deformable cylinder part is provided; when the deformable cylinder part is pressed, the deformable cylinder part is pushed into the retractable folds or the inside of the compressed folds, and the tip of the deformable cylinder part is near the discharge port. Since it is pushed in until the end, almost all of the contents are pushed out without leaving anything behind.

Moreover, since the extrusion can be used until the end while continuing the extrusion work, it is very easy and convenient to use, and it is also economical.

Moreover, since the structure is simple, mass production is possible, and the product can be provided at a lower cost, resulting in an extruded container that exhibits excellent practicality.
