Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flexible tube container containing, for example, cosmetics or toothpaste.

[0002]

[Prior art]

 Generally, a tube container shown in FIG. 4 is known as a tube container for containing toothpaste and the like.

Usually, in such a tube container, one end of a body portion 22 made of synthetic resin is seamed as a bottom portion (not shown), a shoulder portion 27 is provided at the other end, and the shoulder portion 27 is poured. A mouthpiece tube portion 24 for standing is provided upright. In order to take out the contents from such a tube container, the tube container body 22 is pressed to push out the contents.

[0004]

[Problems to be solved by the device]

 However, in the conventional tube container, as shown in FIG. 5, the content remains near the shoulder portion 27 when the content is almost discharged. It is not easy to get this out. That is, the shoulder portion 27 normally spreads like an umbrella, and crushing it is not possible in terms of strength, no matter how flexible the shoulder portion is formed.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a tube container capable of discharging the residue remaining around the shoulder.

[0006]

[Means for Solving the Problems]

 The present invention has a tube body 1 which is formed of a flexible material in a tubular shape and has an interior for accommodating contents 8 for accommodating contents 8 and a shoulder portion 11 for closing the tip of the tube body 1. The tube container having the opening portion 9 provided in the shoulder portion 11 and the mouth tube portion 4 having the spout 4c for pouring out the contents 8 has the following constitution.

That is, the shoulder portion 11 has a linear recess 11 b extending from the one side to the other side of the mouth tube portion 4 and an annular recess 11 c surrounding the mouth tube portion 4, and a straight line The thickness of the inside of each of the recessed portions 11b and the annular recessed portion 11c is configured to be thinner than that of the shoulder portion 11.

Here, the tube body 1 has an elliptical cross section perpendicular to the axial direction, and the linear recess 11b of the shoulder 11 is formed along the major axis direction or the minor axis direction of the ellipse. You may.

The annular recess 11c of the shoulder 11 may be formed in a substantially circular shape. Furthermore, the groove portions of the linear recess 11b and the annular recess 11c may be formed toward the inside of the tube body 1 or may be formed toward the outside of the tube body 1.

[0010]

[Action]

 The thickness of the inside of the linear concave portion 11b of the shoulder portion 11 is formed to be thinner than the thickness of the shoulder portion 11. Therefore, the shoulder portion 11 can be easily bent so that the linear recess 11b becomes a mountain ridge. Furthermore, the wall thickness inside the annular recess 11 c of the shoulder portion 11 is formed thinner than the wall thickness of the shoulder portion 11. Therefore, by applying a force to the mouth tube portion 4, the annular recess 11c can be easily crushed. From the above, it becomes possible to pour out the contents remaining in the vicinity of the shoulder portion 11, particularly in the vicinity of the annular recess 11c.

[0011]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. Note that this embodiment is a mode in which the cosmetic 8 is used as the content.

FIG. 1 is a perspective view of a tube container. The tube body 1 is made of a flexible thermoplastic resin and is formed into a bottomed tubular shape having an elliptical cross section perpendicular to the axial direction. The tube body 1 is not limited to a single synthetic resin, and may be a laminated type in which polyethylene sheets are attached to both sides of aluminum foil, for example.

Further, inside the tube body 1, a content storage portion 3 for storing the cosmetic material 8 is provided. At the tip of the tube body 1, there is provided an elliptical shoulder portion 11 formed of a thermoplastic resin and closing the tip. 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. A mouth tube portion 4 made of hard plastic is erected from the opening portion 9. Further, as shown in FIG. 2, the shoulder portion 11 is provided with a linear concave portion 11b that straddles the mouth cylinder portion 4 along the major axis direction and an annular concave portion 11c that surrounds the circumference of the mouth cylinder portion 4. . The groove portions of the linear recess 11b and the annular recess 11c are formed toward the inside of the tube body 1. Further, as shown in FIG. 3, the wall thickness inside the linear recess 11b and the annular recess 11c is thinner than the wall thickness of the portion 11a of the shoulder 11 other than the linear recess 11c.

A spout 4 c for pouring out the cosmetic material 8 is provided at the tip of the mouth tube portion 4. A male screw 4a is formed around the spout 4c. The cap 10 is screwed through the male screw 4a. In addition, a protrusion may be provided on the outer peripheral surface of the spout 4c and a recess may be provided on the inner periphery of the cap 10 to form a simple concavo-convex connection so that the cap 10 can be attached to and detached from the spout 4c in a one-touch manner.

A positioning protrusion 4b is formed on the outer periphery of the spout 4c. The outer peripheral surface of the cap 10 is screwed onto the outer peripheral surface of the tube body 1 in a uniform shape via the alignment protrusion 4b.

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. Next, the operation of this embodiment will be described.

To dispense the cosmetic material 8 of the tube body 1, the body portion of the tube body 1 is pressed to push the cosmetic material from the spout 4c. When the remaining amount of the cosmetic material 8 is very small, the shoulder portion 11 is bent so that the linear recess 11b becomes a mountain ridge. By this operation, the cosmetic material 8 remaining near the shoulder 11 is pushed out from the spout 4c. Further, when the annular concave portion 11c is crushed by applying a force to the mouth tube portion 4, the cosmetic material 8 remaining in the vicinity of the annular concave portion 11c is also pushed out from the spout 4c. If the groove portions of the linear concave portion 11b and the annular concave portion 11c are formed toward the outside of the tube body 1, the shoulder portion 11 will be easier to bend and crush.
