Abstract

(57) [Problem] To prevent contents such as toothpaste sent in the direction of an outlet in a tube from returning to an original position in a tube main body. SOLUTION: In a crushable tube, a pair of male and female surface fasteners (7a, 7b) for bringing the inner surfaces (5a), (5b) of the tube (1) into close contact with each other is provided on the inner surface of the tube. A tube characterized in that:

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to tubes, and more particularly to collapsible tubes for toothpastes, wasabi, cosmetics and other plastic or semi-liquid materials.

[0002]

[Prior art]

 As such a tube, a flexible tubular laminate tube or the like that deforms when extruding contents such as toothpaste has been used.

[0003]

[Problems to be solved by the invention]

 In the above-mentioned conventional tube, when the contents are taken out, the tube is crushed by pressing the tube with a finger, the contents are sent toward the outlet, and the contents are pushed out from the outlet. However, when the finger pressure is released, the tube returns to its original shape, and the contents sent in the exit direction often return to the original position in the tube. Therefore, the user of the tube must squeeze the tube from the tail toward the outlet each time the contents are removed from the tube. This is a very tedious task. The present invention has been made to solve such a problem in a conventional tube.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is characterized in that a pair of male and female hook-and-loop fasteners for bringing the inner surfaces of the tubes into close contact with each other are provided on the inner surface of the tube. A tube is provided.

[0005]

[Action]

 When starting to use the tube according to the present invention, the user first sends the contents toward the outlet of the tube by pressing the tail of the tube with a finger, and pushes out the contents from the outlet for use. When the tail portion of the tube is pressed, a pair of male and female hook-and-loop fasteners arranged on opposed inner surfaces of the tail portion are engaged with each other to bring the opposed inner surfaces of the tail portion into close contact with each other. Even if the pressing of the tail is released, the hook-and-loop fastener is maintained in the engaged state, so that the tail does not return to the original shape. That is, the content sent from the tail toward the exit does not return into the tail. Thereafter, in the same manner, the user pushes out the contents from the outlet by sequentially pressing the tube from the tail toward the outlet. At this time, the inner surfaces of the tubes are brought into close contact with each other sequentially from the tail to the exit direction by the hook-and-loop fastener. Thus, when the opposing inner surfaces of the tube are brought into close contact with each other by the hook-and-loop fastener, the contact portion of the tube does not return to the original shape. That is, as the tube is used, the inner surfaces of the tube are sequentially brought into close contact with each other in the outlet direction from the tail portion, and do not allow the contents to return. See FIG. Therefore, the user of the tube does not need to squeeze the tube from the tail toward the outlet every time the contents are taken out of the tube, and the tube becomes easy to use.

[0006]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 denotes a collapsible tube for toothpaste, toothpaste, cosmetics and other plastic or semi-liquid materials. The tube 1 is preferably a flexible tubular laminate tube that deforms when extruding the contents 3 such as toothpaste.

According to the present invention, a pair of male and female surface fasteners 7a and 7b for bringing the inner surfaces 5a and 5b of the tube 1 into close contact with each other are provided on the inner surfaces 5a and 5b of the tube 1. The pair of male and female hook-and-loop fasteners 7a and 7b are, for example, a hook tape 7a and a loop tape 7b, and the hook tape 7a and the loop tape 7b are fixed to the inner surfaces 5a and 5b of the tube 1, respectively. Reference numeral 9 denotes an outlet of the tube 1, reference numeral 11 denotes a cap removably attached to the outlet 9, and reference numeral 13 denotes a tail of the tube 1.

[0008]

[Effect of the invention]

 As described above, according to the present invention, a pair of male and female hook-and-loop fasteners are provided on the inner surface of the tube for bringing the inner surfaces of the tube into close contact with each other, so that the user sequentially moves the tube from the tail toward the outlet. When pressed, the inner surface of the tube is brought into close contact with the surface of the tube from the tail to the outlet by the surface fastener, so that the contents are not allowed to return. Therefore, the user of the tube does not need to squeeze the tube from the tail to the outlet every time the contents are taken out of the tube, and the tube becomes easy to use.
