Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tube container that can easily use up the contents stored in the tube container to the end.
[0002]
[Prior art]
At present, for example, toothpaste and cream having a relatively high viscosity are generally sold and used in a tube container having flexibility. This tube container is generally composed of a body part for containing the contents, which is crushed and closed at one end, and a shoulder part for closing the other end of the body part. The cap attached to the neck is removed, the body is pushed as appropriate, and the contents are pushed out from the spout through the neck and used.
[0003]
Such a tube container is equipped with a screw-type or snap-type cap for tightly sealing the contents of the shoulder and neck even though the body is made of a soft material to push out the contents. The structural strength is given by increasing the wall thickness or using a hard separate member. For this reason, the shoulder and neck area are less likely to be deformed than the torso, and it is difficult to completely use the contained contents, and a considerable amount of contents remain when the tube container is discarded. is there.
[0004]
Therefore, many techniques have been proposed for the purpose of reducing the residual amount. For example, there are Japanese Utility Model Laid-Open No. 06-059240, Japanese Patent Laid-Open No. 10-264947, and the like as tube containers that allow the contents to be taken out to the end. The former device disclosed in Japanese Utility Model Laid-Open No. 06-059240 is a device in which grooves of various shapes are arranged on the front side and the back side of the shoulder portion of the tube container so that a part of the shoulder portion can be easily bent. In the last stage, the extrudability of the contents is improved.
[0005]
The latter invention disclosed in Japanese Patent Application Laid-Open No. 10-264947 is a combination of two grooves that pass from the front surface side of the shoulder portion to the periphery of the neck portion, a groove that passes between the grooves, and a groove that radially expands outside thereof. Similarly, the extrudability of the contents is improved by folding the shoulder portion into a substantially flat shape.
[0006]
[Problems to be solved by the invention]
However, in the above-described conventional example, when a groove serving as a fold line is formed on the surface side of the shoulder, the groove is conspicuous, and there is a defect that the appearance of the tube container is impaired.
[0007]
On the other hand, although the example which provides a groove | channel on the back surface side of a shoulder part is also proposed by said conventional example, in such a structure, the position where the groove is formed is not visible to a user, and where is a press part. There is a problem that it is not known which part of the shoulder part can be folded to squeeze out the final contents.
[0008]
Therefore, an object of the present invention is to provide a tube container that can use up the contents to the end, and that is excellent in aesthetics and has a clear position of the pressing portion.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a tube container according to the present invention is formed such that a barrel portion for containing contents and a neck portion for pouring the contents are formed in a central portion, one end of which is crushed and closed. In the tube container having a shoulder portion that closes the other end of the portion, a fixing portion having the neck portion and a pressing portion that is one step lower than the fixing portion are formed on the shoulder portion. A thin step is formed, the step appears outside the shoulder, and the step is made to function as a bent line, so that the pressing portion can be bent along the step , and the pressing portion is The neck portion is deformed so as to surround the neck portion .
[0010]
Moreover, the said press part may give the shape which the both ends extended to the said fixed part side in the boundary line direction with the said fixed part. According to such a structure, when the pressing portion is deformed and folded inside the trunk portion, the both end portions are deformed so as to surround the neck portion, so that the remaining contents are more reliably removed from the neck portion. Can be extruded.
[0011]
