Description

[Detailed description of the invention] [Field of industrial application] This invention is a device for pushing out substances contained in tubes such as tubes containing toothpaste, tubes containing wasabi or mustard, and tubes containing ointment. Regarding.

[Conventional technology]

Tube containers containing toothpaste and wasabi are designed to be used by pushing out the contents by hand. Finally, as shown in FIG. The amount that could not be extruded remains in the part.

Conventionally, as shown in FIG. 9, the amount remaining in this area was often removed by cutting the body X of the tube container body 10 with scissors. Or as proposed in Design Registration No. 549451, No. 10
As shown in the figure, the empty tube container body is sandwiched between the upper plate 20 and the lower plate 21, and in this state, both ends of the upper plate 20 and the lower plate 21 are held with the clips 30, and then Some are pushed up to release the remaining amount.

[Problem that the invention attempts to solve]

As mentioned above, it is troublesome to use scissors to cut off the remaining amount of tube containers, and the extruder for tube containers related to the design registration mentioned above has many parts, and even if this extruder is used, Although it is possible to cleanly remove the remaining amount from the middle of the tube body, it is not possible to remove the remaining amount from the shoulder area.

[Means for solving problems]

This idea was made in view of the above-mentioned problems, and as a means to push out the remaining amount of contents stored in the tube container, two elongated rod-like bodies or elongated plate-like rods are stacked on top of each other so as to leave a narrow gap.
It is characterized by the fact that when stacked, the central part is bent in the longitudinal direction to form a gentle mountain shape, or the top of this mountain shape is a flat part about the diameter of the outlet of the tube container, and in some cases, this mountain shape is The top of the tube is a flat part approximately the diameter of the outlet of the tube container, and one or more protrusions are provided on the flat part.

[Operation] When a tube container with a low amount left is sandwiched between the two stacked upper and lower rods and pushed toward the cap of the tube container, the remaining amount inside the tube container will be released. It is pushed up in the direction and pushed out of the exit. The top of the chevron of this extruder digs into and pushes inside the shoulder near the outlet of the tube container, so the amount remaining in the shoulder of the tube container is pushed up along the gentle chevron of the extruder. and is pushed out the exit. In the case of an extruder with a flat top that is approximately the diameter of the outlet of the tube container, the remaining amount at the shoulder of the tube container can be extruded from the flat part of the tube container to the sloping part, and the top part is flat. If there is a protrusion, you can improve the remaining amount by squeezing the shoulders of the tube to the left and right.

〔Example〕

Specific embodiments of this invention will be described below with reference to the drawings.

FIG. 1 shows a tube container extruder according to this invention, and 1 is a plan view, 2 is a front view, and 3 is a right side view. That is, the round bars are stacked in two to form an upper bar 1A and a lower bar 1B, so that a thin gap 2 is created between the upper bar 1A and the lower bar 1B, and then the upper bar 1A and the lower bar 1B are made.
The extruder 1 for a tube container is designed by bending the central part of the extruder 1 into a gentle mountain shape in a direction perpendicular to the longitudinal direction so that the protrusion 3 is shaped. In this way, by expanding the gap 2 a little, pinching the body of the tube container, and pushing it up, it becomes possible to cleanly push out the amount remaining at the shoulder W of the tube body 10, as shown in FIG.

In addition, as shown in Fig. 2, stack two round bars to form a gap 2 as an upper bar 1A and a lower bar 1B. The tube container extruder 1 may be made by bending the two points, ie, the N point, so that the entire shape becomes a chevron. Furthermore, like this, the center top part is flattened by the flat part 4.
The flat part 4 is provided with a protrusion 5 as shown in FIG.
A single protrusion 5 may be provided, or a plurality of protrusions 5 may be provided as shown in FIG. As mentioned above, in this invention, the round bars are stacked to form a gap 2 as the upper bar 1A and the lower bar 1B, and when the round bars are stacked, a gentle mountain shape is formed at the center in a direction perpendicular to the longitudinal direction. Although the cross section of the round bar does not have to be circular, it may be plate-shaped as shown in FIG. 5. Also, upper bar 1A and lower bar 1B
is made by bending at the end P, but the P part in Fig. 3 2 or the P part in Fig. 4 2 is made by protruding a step 6 on one of the bars to create a gap, as shown in Fig. 6. A protrusion 7 may be provided on this step 6, and a hole 8 into which the protrusion 7 is fitted may be provided on the other side to temporarily fix the upper bar 1A and the lower bar 1B. This fitting method may be provided at one end of the rod or at both ends.

When the body 10 of the tube container, which is running low on remaining amount, is pushed upward through the gap 2 of the extruder 1, the peak of the chevron digs deep into the shoulder as shown in FIG. Most of the contents that were located near the shoulder W near the outlet of the container and could not be pushed out can now be taken out. Incidentally, as shown in FIG. 8, the extruder 1 according to the present invention may be provided with fins 1C in the upper and lower longitudinal directions to make it easier to handle and use.

[Effect of idea]

As explained in detail above, in order to push out the remaining amount in the tube container, this invention consists of stacking two elongated rod-like bodies or elongated plate-like rods so as to create a narrow gap, and moving them in the longitudinal direction while stacking them. It is characterized in that the central part is bent to form a gentle mountain shape, or the top part of the mountain shape is a flat part about the diameter of the outlet of the tube container, and one or more protrusions are provided here. Since this extruder is designed for tube containers, it is possible to cleanly push out the remaining contents in the shoulder of the tube container, such as toothpaste paste, wasabi, ointment, etc., which were difficult to remove in the past. This makes it possible to use almost all of the contents in the tube, which is convenient.
