Description

TECHNICAL FIELD The present invention relates to a quantitative extrusion tube, and more specifically to a quantitative extrusion tube capable of continuously extruding a fixed amount of the content in the extrusion tube by an extremely simple operation. Regarding

2. Description of the Related Art Conventionally, there has been proposed a quantitative extrusion tube having a function of extruding the content in the extrusion tube by a fixed amount (for example, Japanese Utility Model Publication No. 36-27284 and Japanese Utility Model Publication 36-36).
27286 and Japanese Utility Model Publication No. 36-27287) As such a quantitative extrusion tube, there is a quantitative extrusion tube as shown in FIG. In FIG. 5, 50 is a tube container, 51 is its shoulder, and 52 is its mouth.
Reference numeral 53 is a flat-cone-shaped closing plate, which has a slope 53a.
Is located below the inner surface of the shoulder portion 51 and moves up and down to contact the inner surface of the shoulder portion 51. Further, the outer diameter of the closing plate 53 is formed to be equal to the inner diameter of the tube container 50, and the cutout portion 55 is formed on the outer circumference.
Has been excavated or has a somewhat smaller diameter. Further, a small protrusion 54 having a diameter smaller than the inner diameter of the mouth 52 is provided on the top of the closing plate 53. On the other hand, reference numeral 56 is a cap screwed into a male screw threaded on the outer periphery of the mouth portion 52, and a pressing rod 57 that abuts from above is projected on the top surface of the small protrusion 54 at the center of the inner surface thereof. There is.
Then, when the body 50 of the tube container is squeezed by hand, the contents in the tube container 50 are notched 55 in the closing plate 53.
Via the inner surface of the shoulder 51 and the slope 53a of the closing plate 53
Flows into the gap. This is one in which the closing plate 53 is pushed upward by a squeezing operation, and the pushing action of the closing plate 53 moves the contents to the mouth portion 52. Then, after the extrusion of the fixed amount of the content is completed, the slope 53a of the closing plate 53 and the inner surface of the shoulder 51 contact each other, so that the passage to the mouth 52 is blocked and the content is extruded to the outside. Be blocked. Next, when pushing out a certain amount of contents again, the cap 56 is screwed onto the male screw of the mouth portion 52, and the small projection 54 is pushed down by the pushing rod 57 of the cap 56. Then, the closing plate 53 is also pushed down accordingly, and a gap is created between the inner surface of the shoulder 51 and the closing plate 53, and the contents flow into this gap. And
A certain amount of contents can be pushed out again by the squeezing operation.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a conventional device, when a certain amount of content is pushed out of the tube container and then a certain amount of content is pushed out, the cap 56 is removed. The closing plate 5 is screwed into the mouth 52 of the tube container 50 each time.
3 has to be pushed down, which is a troublesome operation.

The present invention has been made in view of such conventional problems, and of course, the cap can be screwed to make it reusable, and further, after pushing out a certain amount of content, an extremely simple operation is possible. It is an object of the present invention to provide a metered extruded tube capable of continuously extruding the content by a fixed amount to the outside.

Means for Solving the Problem To achieve this object, the present invention has a through hole such as a groove 1 penetrating from an outer peripheral surface to an inner peripheral surface, and a cylindrical length (Y) is a neck length (X) of a tube container. ) A metering valve 5 comprising a cylindrical portion 2 configured to be longer and a closing plate 4 having a sloped portion 3 which expands outward from the lower side of the cylindrical portion 2 in an umbrella shape.
Is inserted in the mouth portion 6 of the tube container 7 so as to be slidable in the axial direction.

Operation The operation of the present invention having the above configuration will be described. When the tube container 7 is squeezed by hand, the contents located in the gap between the lower surface of the shoulder 8 and the slope 3 of the closing plate 4 are
It is moved toward the mouth portion 6 of the tube container by the closing plate 4. Then, it flows into the cylindrical portion 2 from the groove 1 of the cylindrical portion 2 of the metering valve 5, and is pushed out of the mouth portion 6 from the opening of the tip of the cylindrical portion 2. The sloped surface 3 of the closing plate 4 comes into contact with the inner surface of the shoulder 8 to complete the extrusion of a certain amount of contents. When the extrusion of the contents is completed, the tip portion 9 of the cylindrical portion 2 slightly protrudes outward from the top surface of the mouth portion 6.
Therefore, when pushing out a certain amount of contents again, the tip portion 9 of the cylindrical portion 2 protruding from the tip of the mouth portion 6 is lightly pressed against a fingertip, a toothbrush, or the like, or the table 1
The quantitative valve 5 can be pushed into the tube container 7 by lightly pressing it against the upper surface of 0 or the like.
By the operation of pushing in the metering valve 5, a gap is created between the inner surface of the shoulder portion 8 and the inclined surface portion 3 of the closing plate 4, and this gap is reduced in pressure. Then, due to this pressure reduction, the contents again flow into the gap, and are squeezed out to be pushed out again.
The contents remaining in the vicinity of the outlet of the mouth portion 6 are sucked into the cylindrical portion 2 by this depressurization, so that the contents are
It can be prevented from dripping. If desired, a metering valve 5
It is also possible to extrude continuously while pushing in. Next, the present invention will be described with reference to the drawings. 1 to 4 are drawings showing a metering extrusion tube and a metering valve according to the present invention. FIG. 1 shows the mouth portion 6 of the tube container 7.
It is sectional drawing which inserted the metering valve loosely inside. In FIGS. 1 to 4, reference numeral 5 denotes a metering valve, which is a cylindrical portion 2
And a closing plate 4 having a slope 3 that expands outward from the lower side of the cylindrical portion 2 in an umbrella shape. A vertical groove 1 is formed in the cylindrical portion 5 so as to penetrate from the outer periphery of the cylinder to the inner peripheral surface (in the embodiment, two vertical grooves are provided). In another embodiment, a plurality of holes can be drilled instead of the groove. That is, the "through hole" referred to in the scope of utility model registration
Is a concept including a plurality of such holes as well as continuous vertical grooves as shown in FIG. The outer diameter of the cylindrical portion 2 is set equal to the inner diameter of the mouth portion 6, and the cylindrical length (Y) is formed longer than the neck length (X) of the mouth portion. Therefore, after the extrusion of a certain amount of the content is completed, the tip portion 9 of the cylindrical portion 5 as shown in FIG. 2 slightly projects from the tip of the mouth portion 6.

Further, the closing plate 4 has a flat conical shape, and the top is closed. FIGS. 1 to 3 show a first embodiment of the closing board 4, and the outside diameter of the closing board 4 is smaller than the inside diameter of the tube container 7. With such a configuration, the contents will flow into the inner surface of the shoulder portion 8 through the gap between the tube container 7 and the outer circumference of the closing plate 4.

As a second embodiment, when the inner diameter of the tube container 7 and the outer diameter of the closing plate 4 are formed to have the same diameter, a notch or a small diameter is bored in the outer periphery of the closing plate 4 to remove the contents. It can flow into the lower surface of the shoulder 8 via a notch or a small hole.

FIG. 3 shows that a plurality of tongue pieces 11 (three in the embodiment) are formed on the outer peripheral end surface of the closing plate 4 when the outside diameter of the closing plate 4 is smaller than the inside diameter of the tube container 7. This can prevent the metering valve 5 from being displaced in the mouth 6 of the tube container 7 due to vibration during transportation to the contents filling factory. That is, the tongue piece 11
Since the tip end of the tube contacts the inner peripheral surface of the tube container 7, it is more reliable to hold the metering valve 5 in a fixed position of the tube container 7 in addition to the guide action by the sliding of the cylindrical part 2 and the mouth part 6. become. Although it is outside the scope of the present invention, the cylindrical portion 2 of the metering valve 5 may be replaced with a rod having a circular cross section or a rectangular cross section formed to have a diameter smaller than the inner diameter of the mouth 6. In this case, it is needless to say that the length of the rod is longer than the neck length of the mouth (not shown).

Effect Conventionally, after pushing out a certain amount of contents, the next time the contents are pushed out, a cap must be screwed into the mouth portion each time, which is very troublesome. However, according to this invention, the metering valve can be pushed into the tube by lightly pressing the end of the cylindrical portion of the metering valve, so that a certain amount of contents can be continuously pushed out, which is convenient.
