Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube container, and more specifically, to a tube container having a sealed bottom portion of a container body.

[0002]

2. Description of the Related Art Conventionally, as a tube container of this kind,
As shown in FIGS. 4A and 4B, the container body 20
In general, the bottom 21 is pressed to form a flat plate-like portion, and the end of the plate-like portion is sealed with a heat seal or the like.

[0003]

However, in the above-described tube container, the length a of the bottom portion 21 of the container body 20 pressed into a flat plate shape for sealing is equal to the length of the container body 20. , And the both ends of the bottom 21 project laterally. Therefore, when the product is packed for shipping, the protruding bottom portion 21 takes more space than necessary, which is inconvenient. Also, when carrying the phone, the user also took unnecessary places, which was inconvenient. Also, when used, the bottom 21 is sharp, so the container main body cannot be erected, and a space for the container is taken up.
It was inconvenient for use.

[0004] The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to eliminate the need for taking unnecessary space when packing products for shipping or carrying the products, and to improve the usability. An object of the present invention is to provide a tube container whose bottom can be sealed to have a good shape of the container body.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, a bottom portion of a cylindrical container body is provided.
Single plate-shaped part formed by pinching only from one direction in the diameter direction
In the tube container obtained by sealing the plate-shaped portion,
A length dimension substantially equal to the length and diameter of the body portion of the container body
In order to shorten it, only the length of the single plate
The concave and convex portions are alternately continuous along the
It is characterized by the following.

[0006]

It stated the operation of the action present invention, the container body bottom
The length of the plate-shaped portion is set to the diameter of the body of the container body so that the sealing plate-shaped portion of the container fits within the outer diameter of the body of the container body.
In order to reduce the length to approximately the same length,
Concave and convex portions are alternately continuous only along the vertical direction
By forming the shape , the bottom portion can be prevented from protruding outside the container body, and the tube container can be made compact. Therefore, space saving can be ensured at the time of packing at the time of product shipment and also at the time of carrying. In addition, since the bottom shape is corrugated, the container body can be erected, and can be conveniently used without taking up a place.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. 1, 2 (a) and 2 (b) are a perspective view, a side view and a bottom view of a first embodiment of the tube container according to the present invention.

As shown in FIG. 1, the container main body 10 is roughly divided into a body 11 having a circular section and forming a housing for cosmetics and the like, and a neck (not shown) having a diameter slightly smaller than the body 11. The lid 12 is detachably screwed onto the neck. In addition, at the bottom 13 of the container body 10,
As shown in FIG. 2A, a plurality of concave portions 14 and convex portions 15 formed of continuous curves are formed in a wave shape.
The end is sealed by a heat seal or the like. The corrugated portions 14 and 15 gradually decrease in width as going upward, and are connected to the upper circular body 11.

The bottom portion 13 of the container body 10 is corrugated with a plurality of concave portions 14 and convex portions 15, and the width of the bottom portion 13 is reduced to a length substantially equal to the diameter of the body portion 11 of the container body. . In short, the bottom 13 of the cylindrical container body 10 is
It was formed by squeezing pressure from only one direction in the diameter direction of the vessel body 10.
Assuming a tube container that seals a single plate
The length of the plate-shaped bottom 13 is adjusted to the body 11 of the container body 10.
This single plate to shorten to a length approximately equal to the diameter of
The concave portion 14 and the convex portion only along the longitudinal direction of the
15 and alternately continued to form a shape.

In addition, the shape of the bottom surface of the seal portion at the end of the bottom portion 13 is such that the plurality of concave portions 14 and convex portions 15 are continuous and corrugated, so that the container body 10 can be erected on a flat surface.

FIG. 3 is a bottom view of the first embodiment having a different bottom shape. In this embodiment, the body 17 of the container body 16 has an elliptical cross section, and has a concave portion 18 and a convex portion 19 at the bottom.
Are formed in a continuous corrugated plate shape. The other parts are the same as those of the first embodiment, and have the same function.

[0012]

[Effects of the Invention] As described above, according to the present invention, a cylindrical shape is provided.
The bottom of the container body in only one direction in the diameter direction of the container body
A tube formed by sealing a single plate-shaped part
In the tube container, the length of the plate-shaped portion is
In order to reduce the length to approximately the same as the diameter of the body,
A concave portion and a convex portion are formed on one plate-shaped portion only along its length direction.
Since the shape is alternately continuous, the width of the bottom of the container body can be made substantially equal to the width of the body, and when packing for shipping products, unnecessary space is not taken and packing can be done neatly. it can. Also, when carrying, the container can be stored neatly. Further, when used, the container main body can be used upright due to the corrugated shape of the bottom.
