[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible tube container containing cosmetics, toothpaste and the like.

[0002]

2. Description of the Related Art A tube container for accommodating toothpaste and the like is generally known as shown in FIG.

[0003] Usually, in such a tube container,
One end of the body 22 made of synthetic resin is connected to the bottom (not shown).
And a shoulder 27 is provided at the other end.
A mouthpiece portion 24 for pouring from 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]

However, in the above-described conventional tube container, the contents remain near the shoulder 27 when almost all of the contents have been taken out as shown in FIG. It is not easy to take it out. That is, the shoulder portion 27 is usually spread in an umbrella shape, and it is impossible to crush the shoulder portion 27 in terms of strength even though the shoulder portion is formed of a flexible material.

[0005] The present invention has been made in view of the above, and an object of the present invention is to provide a tube container capable of discharging the residue remaining around the shoulder.

[0006]

According to the present invention, there is provided a cylindrical body 2 formed of a flexible synthetic resin material and having one end seamed to form a bottom 3, and the other end of the cylindrical body 2. Provided on the side,
The tube container having the umbrella-shaped shoulder 7 and the mouthpiece 4 erected from the spout 8 provided at the center of the shoulder 7 has the following configuration.

[0007] That is, by making a cut 10 in the entire periphery of the lower end of the mouthpiece 4, the wall thickness of this portion is reduced .
The shoulder portion 7 is formed as a thin portion that can be easily crushed toward the bottom 3 side . The shape of the cut 10 can be various shapes such as a U-shape, a semicircle, etc., as long as the lower end of the mouthpiece 4 is made thinner.

[0008]

A cut 10 is made in the entire periphery of the lower end of the mouthpiece 4 and the thickness of this portion is reduced, so that the shoulder 7
Can be easily crushed toward the bottom 3 with the cut 10 as a center. As a result, the inner wall surfaces of the shoulder 7 come into contact with or approach each other, and the contents remaining near the shoulder 7 can be poured out.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. The tube container of the present embodiment is entirely formed of a flexible synthetic resin.

One end of the cylindrical body 2 is formed as a bottom 3 by seaming. An umbrella-shaped shoulder 7 is provided at the other end of the cylindrical body 2. A circular opening 8 is provided at the center of the shoulder 7. The mouthpiece 4 is provided upright from the opening 8, and a spout 6 for discharging the contents is provided at the tip of the mouthpiece 4.

A screw thread 5 is formed on the outer periphery of the barrel 4 to be screwed to a cap (not shown). The cap may be attached or detached by providing a convex portion on the outer periphery of the mouthpiece portion 4 and providing a concave portion on the inner periphery of the cap, so that the cap is simply fitted with the concave and convex portions so that the cap can be detached and attached in a one-touch manner.

The cylindrical body 2 is not limited to a single synthetic resin, but may be a laminated type in which a polyethylene sheet is adhered to both sides of an aluminum foil, for example.

As shown in FIG. 3, the shoulder 7 has a circular joining surface between the cylindrical body 2 and the shoulder 7. As shown in FIG. A notch 10 is formed in the entire periphery of the lower end portion of the mouthpiece portion 4, and the lower end portion of the mouthpiece portion 4 has the shoulder portion 7 on the side of the bottom portion 3 due to the notch 10.
It is formed in a thin portion that can be easily crushed . In addition, the step 12 forming the cut 10 is connected to the upper end of the shoulder 7 so as to surround the opening 8. The cut 10 is shown in FIG.
Although it is formed in a U-shape as shown in FIG. 5, various shapes such as a triangular shape and a semicircular shape may be used as long as the thickness of the lower end of the mouthpiece portion 4 is reduced.

In order to pour out the contents of the tube container, the tubular body 2 is pressed to push out the contents from the spout 6. Then, when the remaining amount of the contents becomes small, as shown in FIG. 2, the shoulder 7 is crushed downward (toward the bottom 3) around the cut 10 at the lower end of the mouthpiece 4. By this operation,
The inner wall surfaces of the shoulder 7 come into contact with or approach each other,
The contents remaining near the shoulder 7 are pushed out from the spout 6.

In this embodiment, as shown in FIG.
Is formed to be larger in diameter than the opening 8, but by making the outer diameter of the barrel 4 smaller or making the wall of the barrel 4 thicker, the spout 6 is It may be formed smaller than the diameter. Further, the spout 6 and the opening 8 may be formed to have the same diameter.

In this embodiment, the shoulder 7 is formed in a circular shape, but the outer periphery of the shoulder may be formed in an elliptical shape.

[0017]

According to the present invention, it is possible to obtain a tube container capable of discharging the residue remaining around the shoulder.
