Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tube squeezing device for simply and accurately squeezing out the contents of a laminated tube or the like.

(Prior Art) Conventionally, a tube consists of a pair of elongated clamping pieces that are connected at one end with spring properties and open at the other end, and clamp the tube body inserted through the open part in the width direction. Each open end of the clamping piece is curved toward the tip so that the distance between them gradually decreases;
One of the pair of clamping pieces has a lower end side perpendicular to the longitudinal direction that is gradually bent inward toward its edge, and a portion of the other clamping piece that faces this bent part is cut out. Tube squeeze devices are known.

However, with such a tube squeezing device, when inserting the tube body into the interior from the open end of the pair of clamping pieces, it is not only difficult to insert it, but also because the gap on the tip side gradually narrows. However, providing a bent portion on one side of the clamping piece and a cutout portion on the other side complicates the manufacturing process, making it impossible to reduce manufacturing costs.

(Purpose of the invention) In view of the above-mentioned problems found in the conventional ones, the purpose of the present invention is to provide a tube squeezing device that can be easily inserted into the tube body and can be manufactured at low cost. do.

(Structure of the invention) In order to achieve the above purpose, the present invention
The a sides are connected to each other with spring properties, and the other end 1
In a tube squeezing device consisting of a pair of elongated clamping pieces 10 that open the 0b side and clamp the tube body inserted through the open part 11 in the width direction, each open end 10b of the clamping pieces 10 is placed on the tip side. The cut portions 10d are curved so that the interval between them gradually increases toward the end, and the lower end 10c, which is perpendicular to the longitudinal direction of the holding piece 10, is provided near both ends in the longitudinal direction. It is characterized by the fact that it used to be curved so that the intervals gradually narrowed.

(Function) According to the present invention, the open ends 10b of the clamping piece 10 are curved so that the distance between them gradually increases toward the distal end, so that the insertion work into the tube body becomes easy and quick. In addition, the lower end 10c side perpendicular to the longitudinal direction of the clamping piece 10 is bent inside each cut part 10d provided near both ends in the longitudinal direction so that the interval becomes gradually narrower toward the edge side. The lower end 10c of the clamping piece 10 is pushed up above the tube body while the clamping piece 10 is clamped by the tube body.
can accurately push up the contents of the tube body 10 from both sides thereof, and can sufficiently prevent the holding piece 10 itself from being pushed back by the repulsive force of the contents.

(Example) The drawing shows an example of the present invention.
0 is a pair of clamping pieces that clamp the tube body A in the width direction, one end 10a of which is connected to each other with spring properties, and the other end 10b is released, and a release part 11 into which the tube body A is inserted. Eggplant. Clamping piece 10
The other end 10b side is curved so that the distance between them gradually increases toward the tip side, and the lower end 10c side, which is perpendicular to the longitudinal direction of the clamping piece 10, is curved toward the edge side except for both ends in the longitudinal direction. They are bent so that the distance between them gradually narrows as they face each other. Note that 10d is a cut portion provided to bend the lower end 10c side of the holding piece 10.

As described above, the tube body A
If the release portion 11 of the clamping piece 10 is placed against one side of the bottom end of the tube body A and pushed in as is, the tube body A is smoothly inserted into the clamping piece 10 and is securely clamped in the width direction by the spring force of the other end 10a of the clamping piece 10. Therefore, by pushing the clamping piece 10 upward on the tube body in this state, the bottom end 10c (bent portion) of the clamping piece 10 will accurately push up the contents of the tube body 10 from both sides, and the contents will be easily and accurately squeezed out.
Since the lower ends 10c (bent portions) of the clamping pieces 10 contact both sides of the tube body 10, the clamping pieces 10 themselves are sufficiently prevented from being pushed back by the repulsive force of the contents.

(Effect of the invention) As explained above, according to the invention, one end side is provided with spring properties and connected to each other, the other end side is open, and the tube body inserted through the open part is clamped in the width direction. In a tube squeezing device consisting of a pair of elongated clamping pieces, each open end of the clamping pieces is curved so that the distance between them gradually increases toward the distal end, making it easy to insert the clamping pieces into the tube body. In addition, the lower end side perpendicular to the longitudinal direction of the clamping piece is bent at the inner side of each cut portion provided near both ends in the longitudinal direction so that the interval gradually narrows toward the edge side, so that the clamping can be performed quickly. By pushing up the clamping piece above the tube body with the piece clamped by the tube body, the lower end of the clamping piece can accurately push up the contents of the tube body from both sides, and the clamping piece itself Sufficiently prevents the contents from being pushed back due to repulsive force. Furthermore, the bending angle of the bent part inside each cut part can be adjusted as appropriate, and the curvature of the curved part can also be easily adjusted, so it is possible to always obtain the optimal clamping force according to the thickness of the tube body. Since there is no need to cut out the portion of the other clamping piece that faces the bent portion, there are advantages such as lower manufacturing costs.
