影響によるシール不良がある等の欠点があつた。(Conventional technology) Conventional tube containers can be roughly divided into aluminum tubes and laminated tubes (the body of which is made of aluminum foil,
Brooches (made of a laminate structure of paper, plastic film, etc., with a plastic-molded shoulder and nozzle part integrally welded to the upper end and sealed at the lower end) and brooches (made of plastic formed by blow-molding) However, while aluminum tubes have the advantage of preserving the contents, they not only cause unevenness on the body of the container during use, damaging its appearance.
There were drawbacks such as cuts in the body due to the use of the tube container when it was rolled up. Further, in the case of a laminate tube, since the body has a laminate structure, it not only has excellent printing properties, but also has the advantage that unevenness is less likely to occur during use of the container due to the restorability of the body. However, on the other hand, since the plastic molded parts of the bottom and nozzle parts are made of a single material such as polyethylene, there is a problem of moisture permeation, and there is also a problem with the sealing part at the lower end of the body due to the influence of the inner paper. There were defects such as defects.

いる。 On the other hand, broach tubes have the advantage of being able to select the most suitable plastic material regardless of the type of contents, and can be finished into any tube shape by blow molding. It is also possible to integrally mold the layers into a so-called laminate structure, and this integral molding has various advantages such as there being no risk of sealing failure on the inner wall surface of the tube.

た。(Problems to be Solved by the Invention) Brooch tubes are widely used based on the various advantages mentioned above. Because the material is mainly used, when the tube body is pressed to squeeze out the contents, the restoring force of the tube body sucks in outside air (creating a so-called air bag), so if it is left as is for a long period of time. In some cases, the air inside the container may cause the contents to change in quality or harden, causing storage problems. In addition, if an air bag occurs, when the contents are squeezed out the next time it is used, the contents are ejected with air trapped inside them, causing problems such as making unpleasant noises.

The objective is to improve the performance of the device and to avoid making unpleasant noises during use.

まれるのを阻止し得る。(Function) In the present invention having the above configuration, when the pressing operation on the container body is stopped after using the contents,
The contents that have already flowed into the nozzle passage tend to flow back into the container body due to their own weight and the suction force from inside the container body. However, when the contents in the nozzle passage near the small diameter part pass near the constriction part, which has an even smaller opening cross-sectional area than the small diameter part, the pressure increases due to the throttling action, and this increases the viscosity of the contents. Backflow into the container body is prevented.
As a result, the nozzle passage is blocked by the content itself remaining in the nozzle portion, and air can be prevented from being sucked into the container body.

As a result, rapid pressure changes on the contents during extrusion are alleviated, and the contents can easily flow through the nozzle passage.

ている。(Embodiment) The present invention will be explained below based on the illustrated embodiment. FIGS. 1 and 2 show an embodiment of the dispensing structure of a tube container according to the present invention, and 1 is a blower. The container body 1 is made of synthetic resin and is formed by molding, and the container body 1 is provided with a cylindrical nozzle portion 12 having an opening 11 on a shoulder portion 10 thereof. The nozzle part 12 has an inner diameter R 2 near the opening.
a narrowed portion 12 having a circular cross section and formed continuously at the lower edge of the small diameter portion 12a, that is, the edge on the shoulder portion 10 side, and locally narrowing the nozzle passage A.
c, and a large diameter portion 12b which is connected to the lower end of the constricted portion 12c, that is, the edge on the shoulder portion 10 side and has an inner diameter R3 .

ある。 Here, the opening cross sections of the small diameter portion 12a and the large diameter portion 12b are approximately circular, and their inner diameters R 2 and R 3 are formed so that R 2 <R 3 as shown in FIG. That is, the opening cross-sectional area of the large diameter portion 12b is smaller than that of the small diameter portion 1.
The cross-sectional area of the opening 2a is larger than that of the opening 2a. Further, as shown in FIG. 1, the inner diameter R 1 of the throttle part 12c is smaller than the inner diameters R 2 and R 3 , and the opening cross-sectional area is also smaller than the opening cross-sectional areas of the small diameter part 12a and the large diameter part 12b. There is. Therefore, this constriction part 12c performs a constriction action that restricts the passage of the contents when the contents try to flow back through the nozzle passage A after the dispensing operation. Reference numeral 13 designates convex portions provided on the outer periphery of the constricted portion 12c at intervals of approximately 90°, and serves as ribs for reinforcing the constricted portion 12c, which has a small opening cross-sectional area. Reference numeral 14 denotes a threaded portion provided on the outer periphery of the large diameter portion 12b for attaching the cap 2.

is provided with a threaded portion 21 on the inner periphery of its inner peripheral wall 20, and the threaded portion 21 is connected to the threaded portion 14 of the container body.
It is designed to be screwed together.

押出することができる。 When taking out the contents of the tube container configured as described above for the intended purpose, after removing the cap 2, press the body of the container body 1 and move the contents through the nozzle passage A to the opening 11. so that it is extruded from the outside. In this case, large diameter part 1
The opening cross-sectional area of 2b is larger than the opening cross-sectional area of the small diameter part 12a, and since the contents once pressurized in the large diameter part 12b pass near the constriction part 12c, the pressure change on the contents is alleviated, and the nozzle Passage A
Contents can easily flow inside. Therefore, the contents can be easily extruded through the nozzle part 12 in which the constricted part 12c is formed.

ができる。 Next, when the use of the contents is finished and the pressing operation on the container body 1 is stopped, the flow of the contents inside the container body 1 is also stopped. In this case, the contents that have already flowed into the nozzle passage A will be affected by their own weight and the container body 1.
Although the suction force from inside tries to flow back into the container body 1, the contents in the nozzle passage A near the small diameter section 12a flow around the constricted section 12c, which has an even smaller opening cross-sectional area than the small diameter section 12a. During the passage, the pressure is increased by the throttling action, which, together with the viscosity of the contents, prevents the contents from flowing back into the container body 1. As a result, the nozzle passage A is blocked by the content itself remaining in the nozzle part 12, and air can be prevented from being sucked into the container body 1, making it possible to completely prevent the occurrence of air bags. can.

を図ることができるという効果もある。 In addition, since the constriction part 12c of this embodiment is provided with a reinforcing convex part 13, the nozzle part 12 will not bend due to some load, and the cap can be removed smoothly. . Furthermore, due to the reinforcement by the convex portion 13, the constricted portion 12c
Since the cross-sectional area of the opening can be made smaller and the throttle effect can be enhanced, there is also the effect that air bags can be further prevented.
