Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an extrusion tool used for extruding toothpaste, glue, paint, cosmetics, medicine, and other contents contained in tube containers.

[Conventional technology]

Generally, the contents of a tube container are used by removing the cap and pushing the contents upward from the bottom of the container. Aluminum tube containers are used by being folded from the bottom end as the contents decrease, but the container cannot be folded properly all the way, and the container does not feel good to the touch, but wrinkles along the way. There is a problem that the contents remain in the parts that have been removed. Also, although plastic tube containers have a nice texture, they cannot be folded, so when pushing out the contents, you must push the contents up from the bottom of the container to avoid pushing the contents back toward the bottom. However, there are some problems that make it difficult to use.

Therefore, in order to solve the above-mentioned problems, the first conventional example described in Publication of Utility Model Publication No. 53-50674, the second conventional example described in Publication of Utility Model Publication No. 53-525, and the second conventional example described in Publication of Utility Model Publication No. 8 There is a third conventional example described in Publication No. -7776.

In the first conventional example, the aperture piece is expanded by pulling outward the half rings attached to both sides of the extension part of the aperture piece and disengaging the protrusions formed on both sides of the base end of the aperture piece. While holding the aperture piece with both hands, place your thumbs on the parallel protrusions formed on the extension of the aperture piece and push it open, expanding the tube insertion hole and separating the teeth. The configuration is such that the operation of inserting the tube tail, then restoring and closing the aperture piece, and hooking the half ring to the protrusion is repeated.

A second conventional example is a squeezed body made of a synthetic resin material that forms a tube insertion passage having a tube insertion opening and an outlet, and connects both clamping pieces forming the insertion passage with a connecting piece on which a thin hinge is formed. At the same time, the insertion passage is formed into a curved passage in which a convex surface provided on the inside of the clamping piece communicates with a concave surface corresponding thereto, and the tube is flattened into the communicating curved passage. The structure consists of a protruding zenith section.

Further, in the third conventional example, both side walls of the pedestal are provided, a shaft is installed on the both side walls, and a cylindrical part, which is one end of the extruded curved plate, is rotatably fitted onto the shaft, and the extruded curved plate is mounted in the cylindrical shape. The outer surface of the shaped portion is formed into a smooth convex surface from the root surface toward the other end.

[Problem that the invention attempts to solve]

However, the first conventional example has a complicated structure, is difficult to operate, and is expensive compared to the cost of the tube. In addition, in order to remove a completely empty tube from the squeezing tool, it is necessary to cut the flat tube part that protrudes outside the elastic plate at the part where it is bitten by the teeth, and then pull it out from the knob on the mouth side of the tube to remove it. There is also a problem.

In the second conventional example, since the corners of the hook-shaped lever are not rotatably supported on both end surfaces of one extrusion member, there is a risk that the contents may return to the rear, and the tube It cannot fulfill the role of a stopper to keep it in a pinched state.

In addition, in the third conventional example, when the extruded curved plate is in the upper position, the distance between the root surface and the pedestal is slightly increased, and when the extruded curved plate is rotated downward, the root surface and In order to be able to apply strong pressure to the tube between it and the cradle, the precision of parts processing must be high, and if you try to remove the contents by pulling out the bottom of the tube, the extrusion curved plate will rotate upwards due to the pressure. Otherwise, the contents of the tube may fall back. Therefore, there is a problem in that it is necessary to press the extruded curved plate, and when the extruded curved plate is pushed too far, the bottom of the tube needs to be folded and used repeatedly.

[Means for solving problems]

Therefore, the present invention aims to provide an extrusion tool that can reliably, quickly and easily extrude the contents contained in this type of tube container to the end.

That is, the extrusion tool of the present invention has two extrusion members 1a, 1
One end of b is connected by a hinge 2, and the other end is configured to engage and disengage with each other, and a tube container 4 is pressed into contact with the front and rear facing parts and the center facing part of the two extrusion members 1a and 1b, respectively. Two openings 5 and 6 are slidably inserted through the openings, and a communicating portion 7 connecting these openings is formed.One extrusion member is provided with a lever opening 8, and both ends of one extrusion member are inserted into the opening 8. The corner portion of a hook-shaped lever 10, which presses and locks the tube container 4 with the inner surface of the other extrusion member, is rotatably supported on the surface portion.

[Effect]

While the tube container 4 is new and has enough contents, remove the cap of the tube container 4 and press the lower end (bottom) with your finger, or press the locking structure 3.
If the extrusion members 1a and 1b are disengaged from each other, and the lower end of the tube container 4 is held between the opening 5 of one side and the extrusion members 1a and 1b are engaged, the contents will be pushed out by the opening 5. It will be done. As the extrusion of the contents progresses, the tube container 4 is pressed not only by the opening 5 but also between the hook-shaped lever 10 and the inner surface 9 of the extrusion member 1b, and is further pressed by the openings 5 and 6. At the same time, it is pushed out between the hook-shaped lever 10 and the inner surface 9 of the pushing member 1b.

In this state, the tube container 4 is pressed in a bent state, so that the pressed state can be maintained reliably.
If you want to push out the contents further, pull the lower end (bottom) of the tube container 4, and the hook-shaped lever 1
0 rotates around the pivot shaft 11, and the tube container 4
is pressed by the ports 5 and 6 to force out the contents.

After pushing out the contents by a predetermined amount, press the hook-shaped lever 10.
can be rotated in the opposite direction about the pivot shaft 11 to lock the tube container 4 in the pressed state.

〔Example〕

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

In this example, two plastic extruded members 1 are used.
One end portions a and 1b are connected by a hinge 2, and the other end portions are made into an engaging/disengaging structure 3 that can be engaged with and separated from each other. The locking/disengaging structure 3 includes, for example, a locking portion 3a connected to one end of one extrusion member 1a, and an engaging portion 3b with which the locking portion 3a engages to one end of the other extrusion member 1b. , its structure is not limited to the illustrated example.

Two openings 5, 6 into which the tube container 4 is slidably inserted, and a communication portion 7 connecting these openings 5, 6 are formed in the front and rear facing parts and the central facing part of the two extrusion members 1a, 1b, respectively. However, one extrusion member 1a is provided with a lever opening 8. In this opening 8, the tube container 4 is attached to both end surfaces of one extrusion member 1a on the inner surface 9 of the other extrusion member 1b.
A corner portion of a hook-shaped lever 10 for press-locking between the two is rotatably supported by a pivot shaft 11.

In the above configuration, while the tube container 4 is new and has enough contents, remove the cap 4a of the tube container 4 and press the lower end (bottom) with your finger, or press the tip 3a ₁ of the locking part 3a. Apply force in the direction of the arrows in FIGS. 1 and 2 to deform it and release the engagement with the engaging part 3b, and then pinch the lower end of the tube container 4 between the openings 5 and the engaging part 3a. and engaging part 3
When b is engaged, the mouth 5 is pressed and the contents are pushed out. As the extrusion of the contents progresses, the tube container 4 is pressed not only by the mouth 5 but also between the hook-shaped lever 10 and the inner surface 9 of the extrusion member 1b, and further as shown in FIG. At the same time, it is pressed by the openings 5 and 6 and is pushed out by being pressed between the hook-shaped lever 10 and the inner surface 9 of the pushing member 1b.

In the state shown in FIG. 3a, the tube container 4 is pressed in a bent state, so that the pressed state can be maintained reliably. If you want to push out the contents further, press the lower end (bottom) of the tube container 4 as shown in Figure 3a.
When pulled to the left at , the hook-shaped lever 10 rotates clockwise about the pivot shaft 11 to the state shown in FIG. being pushed out.

After pushing out a predetermined amount of the contents, the tube container 4 is rotated counterclockwise around the pivot shaft 11 by rotating the hook-shaped lever 10 as shown in FIG. 3a. can be locked in the pressed state.

[Effect of idea]

As is clear from the above description, the extrusion tool of the present invention has the effect of being able to reliably, quickly and easily extrude the contents contained in the tube container to the end. In addition, the structure is simpler and easier to operate than the above-mentioned conventional example, and not only can it be implemented at a low cost, but also the corner part of the hook-shaped lever is rotatably supported, so that the contents can be easily controlled. The function of the stopper is that there is no risk of objects returning backwards, and when not in use, the tube container is held in a bent state between both mouths, one end of the lever, and the inner surface of the other extrusion member by rotating the lever. When in use, by pulling the bottom of the tube container, the lever can be rotated in the opposite direction to release the stopper function, and the tube container can be pulled out while being squeezed with both mouths to remove the contents. It has the following effects.
