[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the tube container according to the present invention is formed into a tubular shape with a flexible material, and has a tube main body 1 having a content storage portion 3 for storing the content 8 therein, 1 is provided with a shoulder portion 11 that closes off the tip end, and a mouth tube portion 4 that is provided upright from an opening portion 9 provided in the shoulder portion 11 and that has a spout 4c that pours out the contents 8.

A strip-shaped thin portion 12 that crosses the shoulder portion 11 and the mouth tube portion 4 is provided from one side to the other side of the shoulder portion 11. Here, the strip-shaped thin portion 12 is formed so that the thickness thereof is thinner than the thickness of other portions where they are provided.

The present invention can be implemented in various forms as shown below. First, the tube body 1 is made of a single synthetic resin, a laminated type made by adhering a plurality of synthetic resins, a thermoplastic resin film, or a metal foil (for example, aluminum foil) on both sides. It can be formed from a material coated with a thermoplastic resin, a metal film deposited by vapor deposition, paper or the like coated on both sides with a thermoplastic resin.

Further, the outer shoulder portion 11 and the mouth tube portion 4 are made of synthetic resin or the like, and those having good adhesiveness to the tube body 1 are selected. The portion of the strip-shaped thin portion 12 provided on the shoulder portion 11 can be formed so that the cross section perpendicular to the length direction is concave. In this case, the recess may face either the inside or the outside of the shoulder 11.

[0010]

[Action]

 When the content container 3 is sufficiently filled with the content 8, the body of the tube body 1 is narrowed down in the distal direction. By this narrowing down, the contents 8 are poured out from the spout 4c.

Then, in a state where the content 8 stored in the content storage portion 3 is running low, the portion of the strip-shaped thin portion 12 provided on the shoulder 11 is pressed from both one side and the other side. . By this pressing, the shoulder portion 11 is crushed, and the contents 8 remaining around the shoulder portion 11 can be poured out from the spout 4c.

Here, in a state where the content 8 stored in the content storage portion 3 is further reduced, the portion of the strip-shaped thin portion 12 provided in the mouth tube portion 4 is pressed from both one side and the other side. To do so. Due to this pressing, the mouth cylinder part 4 is crushed, and the contents 8 remaining inside the mouth cylinder part 4 can be poured out from the spout 4c.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this Example is a mode in which the paste cosmetic 8 is used as the content.

First, the configuration of the embodiment will be described with reference to FIGS. 1, 2 and 3. 1 and 2 are partial cross-sectional views of the tube container in the embodiment. FIG. 3 is a plan view of the tube container in the example. In FIG. 1, the tube container has a tube body 1 made of a flexible thermoplastic resin and formed into a tubular shape having an elliptical cross section perpendicular to the axial direction.

At the base end of the tube body 1, a bottom seal portion 2 that closes the base end is provided. In addition, an elliptical shoulder portion 11 formed of synthetic resin and closing the front end is provided at the tip of the tube body 1. Although the joint surface between the shoulder portion 11 and the body portion of the tube body 1 is formed in an elliptical shape, the joint surface is not limited to the elliptical shape and may be formed in a circular shape, for example.

A circular opening 9 is provided in the center of the shoulder 11. From this opening 9, a mouth cylinder 4 formed of synthetic resin in a cylindrical shape is erected. A spout 4c for pouring out the kneaded cosmetics 8 is provided at the tip of the mouth tube portion 4. A male screw 4d is formed on the outer circumference of the spout 4c. A cap (not shown) is screwed through the male screw 4d. It should be noted that a projection may be provided on the outer circumferential surface of the spout 4c and a recess may be provided on the inner circumference of the cap to simply form a concavo-convex connection so that the cap can be attached to and detached from the spout 4c in a one-touch manner.

Although the spout 4 c is formed to have a smaller diameter than the opening 9 in this embodiment, the spout 4 c may be formed to have a smaller diameter or the same diameter than the opening 9. As shown in FIG. 3, the shoulder 11 is formed with a shoulder recess 12a that traverses the major axis direction of the shoulder 11 from one side to the other side. The recess of the shoulder recess 12a is formed to face the inside of the tube body 1. Further, the thickness of the inner bottom portion of the shoulder recess 12a is thinner than that of the other portion 11a of the shoulder 11.

As shown in FIG. 1, a mouthpiece thin portion 12b is formed at a portion of the base end of the mouthpiece portion 4 which is connected to the shoulder recess 12a. The mouthpiece thin portion 12 b is formed thinner than the other parts of the mouthpiece portion 4. Here, the mouthpiece thin portion 12b and the shoulder recess 12a are collectively referred to as a belt-shaped thin portion 12. The upper tube portion 4e of the mouth tube portion 4 is not thinned.

Next, the operation of this embodiment will be described. When the content container 3 is sufficiently filled with the kneading cosmetics 8, the body of the tube body 1 is narrowed down in the tip direction. By this narrowing down, the paste cosmetic 8 comes to be poured out from the spout 4c through the opening 9.

Then, when the amount of the kneading cosmetics 8 stored in the content storage portion 3 is low, the shoulder recess 12a is pressed from both one side and the other side. By this pressing, the shoulder portion 11 is crushed, and the kneaded cosmetic product 8 remaining around the shoulder portion recess 12a is poured out from the spout 4c.

Here, when the amount of the kneading cosmetics 8 stored in the content storage portion 3 is further reduced, the mouthpiece thin portion 12b is pressed from both one side and the other side. Due to this pressing, the mouth tube portion 4 is crushed, and the kneaded cosmetic product 8 remaining inside the mouth tube portion 4 is poured out from the spout 4c.

As described above, in the tube container of the embodiment, the amount of the kneaded cosmetic product 8 remaining in the tube container is increased by pouring out the kneaded cosmetic product 8 remaining around the shoulder portion 11 and the mouth tube portion 4. Can be reduced.

Here, when the kneading cosmetics 8 are left in the contents accommodating portion 3, it is preferable to attach a cap to the mouth tube portion 4. In this embodiment, the upper portion of the mouth tube portion 4 is not thinned. Therefore, the sealing property between the mouth tube portion 4 and the cap is good, the contents do not leak, and the mouth tube portion 4 is kept in a good shape.
