[Prior art]
Conventionally, a metal tube made of aluminum, lead or the like has been used as a tube container for storing an adhesive or the like in consideration of storage stability and water resistance of contents. 7 and 8 are views showing a metal tube and a composite container for storing a conventionally used adhesive and the like. The conventional metal tube shown in FIG. 7 is a metal tube that prevents dripping. That is, since the conventional metal tube has no restoring force in the body part once pressed, there is a defect that if the body part is pushed too much, the contents are extracted more than necessary and the sag phenomenon occurs. This phenomenon was particularly remarkable when the content was a low-viscosity liquid or the like. In FIG. 7, in order to eliminate this drawback, an elastic body 51 such as a synthetic resin is inserted into the metal tube 50, and the body portion of the metal tube 50 has a restoring force, thereby preventing the liquid dripping phenomenon. It is an embodiment.

Further, the conventional composite container shown in FIG. 8 shows a conventional embodiment in which a pressure medium 54 such as a fluid liquid, powder or solid is sealed between an inner container 52 and an outer container 53. The pressing force from the outer container 53 is transmitted to the inner container 52 through the pressure medium 54, and the contents in the inner container 52 are extracted to the outside.
[0004]
[Problems to be solved by the invention]
However, such an invention has the following drawbacks.
(1) In the conventional embodiment shown in FIG. 7, when a liquid such as a low-viscosity adhesive is stored, in order to exert the effect of preventing dripping, the elastic force with a strong resilience and elasticity The body 51 must be inserted into the metal tube 50. When such an elastic body 51 is inserted into the metal tube 50, the body portion of the metal tube 50 must be pressed with a remarkably strong force. There was a drawback that the contents could not be extracted, and there was a disadvantage that it was hard to use for powerless children and women.
(2) In the conventional embodiment shown in FIG. 8, the gap 54 between the inner container 52 and the outer container 53 is filled with a pressure medium 54 such as liquid, powder or solid. Since the pressing force is directly transmitted to the inner container 52 through the pressure medium 54, there is a disadvantage that the contents such as the adhesive are excessively larger than desired, and the outer container 53 is covered with the lid 55. As the outer container 53 is damaged, there is a risk of contamination, and the manufacturing cost increases. It was.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show a first embodiment of the present application. Reference numeral 1 denotes a metal interior tube that houses a content 2 such as an adhesive. Examples of the metal include aluminum, tin, lead, and the like. In the case of aluminum, the material can be softened by annealing. Reference numeral 3 denotes an outer tube that houses the inner tube 1, and the outer tube 3 is a quay outer tube made of a synthetic resin with a mouth cut. In the first embodiment, the shoulder portion 3b of the truncated outer tube 3 is brought into contact with the side surface of the shoulder portion 1b so that the lateral direction of the shoulder portion 1b of the inner tube 1 can be regulated. It is deformed to.
[0008]
The present invention has the following features. First, when the interior tube 1 and the pier outer tube 3 are assembled, the mouth portion 1a is exposed upward from the opening 3a of the berth outer tube 3. The female screw portion of the nozzle 4 is screwed into the exposed male screw portion of the mouth portion 1a, and the nozzle 4 is firmly fixed to the mouth portion 1a.
[0009]
Secondly, as shown in FIG. 2, the lower end 4 a of the nozzle 4 is lowered as a means for bringing the shoulder 1 b of the inner tube 1 and the shoulder 3 b of the wharf outer tube 3 into close contact with each other. The point is to contact the shoulder portion 3b of the outer hood tube 3. As a result, the gap 5 is completely sealed. At this time, the guide 8 connected by the thin wall portion is separated from the nozzle 4 by the lower end portion 4a as shown in FIG. Thirdly, a step is provided in the hole diameter of the nozzle 4. That is, by changing from the large hole diameter 4c (dimension A) to the thin hole diameter 4d (dimension B) at the tip of the nozzle 4 (A> B), when the container is pressed downward, the thick hole diameter 4c portion Is easily replaced with the contents 2, so that the large bubbles existing in the contents 2 such as the adhesive in the interior tube 1 move to the interior tube 1 side and are not released to the outside, but only the contents 2. Is effective. A cap 7 is screwed or fitted to the outer periphery of the upper portion of the nozzle 4, and a projecting portion 4 b for breaking through the sealing lid 6 of the interior tube 1 is suspended from the top surface portion of the female screw portion of the nozzle 4. ing.
[0010]
3 and 4 show a second embodiment of the present invention. The difference from the first embodiment is that the guide 8 is not provided on the outer periphery of the lower end portion 4a of the nozzle 4, but is a female. It is a point provided through the thin part directly under the screw part. And the lower end part 4a formed in the outer periphery of the nozzle 4 is made to contact | abut on the shoulder part 3b of the truncated outer tube 3. Note that the shoulder portion 1b of the inner tube 1 does not have to be regulated in the lateral direction by the wharf outer tube 3 as in this embodiment. Other configurations are the same as those of the first embodiment.
[0011]
Next, the operation of the present invention will be described. In the first embodiment, when extracting the contents 2 such as the adhesive from the composite container according to the present application, when the nozzle 4 is rotated and lowered by the finger, the guide 8 is pressed by the lower end portion 4a, and the nozzle 4 The thin-walled portion connected to is cut off from the nozzle 4. And the lower end part 4a contacts directly on the shoulder part 3b of the truncated outer tube 3. The virgin property of the composite container according to the present application can be checked based on whether or not the guide 8 is cut.
[0012]
When the lower end portion 4a is further lowered, as shown in FIG. 5, the shoulder portion 3b comes into strong contact with the shoulder portion 1b of the interior tube 1, and the gap portion 5 is completely sealed and held in the air-filled state. The At the same time when the lower end 4 a is lowered, the protrusion 4 b of the nozzle 4 breaks through the sealing lid 6. After that, as shown in FIG. 6, the gap portion 5 of the truncated outer tube 3 is sealed, so that when the body portion 3 c of the truncated outer tube 3 is pressed, the pressing force is applied to the inner tube 1 through the gap portion 5. It is indirectly transmitted to the trunk 1c. That is, the feature of the operation of the present invention is that the finger pressing force is indirectly transmitted using air as a medium, so that the inner tube 1 can be slightly deformed and restored. Further, since the nozzle 4 is composed of two stages of a thick hole diameter 4c and a thin hole diameter 4d, when the container is pressed downward, the bubbles in the thick hole diameter 4c move to the interior tube 1 side, and the contents 2 Only, and the pressing force required for this can be reduced. Furthermore, by the indirect transmission of the pressing force through the gap 5 and the interaction of the nozzle structure, the internal tube 1 is kept in its original shape by small elastic deformation, that is, without causing plastic deformation. In the state, the content 2 is poured out. For this reason, a small amount of the contents 2 can be poured out, dripping is prevented, and the entire contents 2 can be used up easily.
[0013]
【The invention's effect】
