Description

  The present invention relates to a tube container, and more particularly, to a tube container for the purpose of improving the ability to use the contents and reducing the remaining amount of the contents in the tube.

  Conventionally, various forms have been used for tube containers containing cream-like or gel-like cosmetics as contents. These tube containers are composed of a cylindrical body portion having a cap and a conical shoulder portion having a take-out port portion into which the cap is screwed. Then, after filling the contents, the other end of the take-out port portion of the cylindrical body portion is sealed, and the content is taken out from the take-out port portion by pressing the cylindrical body portion. In the tube container having such a configuration, it is difficult to use up the contents completely, and there is a problem that the contents remain in the shoulder portion and the outlet portion.

  Various studies have been made to solve such problems. For example, a tube container (Patent Document 1) or a cylinder that improves the extrudability of the contents by providing a concave groove around the cylindrical body part having a continuous conical shoulder and reduces the remaining amount of the contents. There has been proposed a tube container (Patent Document 2) that has two layers of cylindrical body portions, is provided with air holes at positions that are easy to push, and can pressurize the contents.

However, in the above-mentioned type of tube container, there is a problem that the contents remain in the outlet, the cost of the tube container itself increases, or a problem that the design is limited. The problem that it is difficult to adopt as is occurring.

    The problem to be solved is that there is no restriction in design, the content can be used up, the remaining amount of the content in the tube is reduced, and the content can be easily removed when the content is used up. The provision of containers.

  In order to solve the above-mentioned problems, the inventor has intensively studied, and as a result, an extruded tube having a cap, a cylindrical body portion, a shoulder portion, and an outer periphery of a take-out port portion to be screwed to the cap is constituted by a screw portion. In the container, by providing a concave groove in the screw part and shoulder part, when the contents are used up, the take-out part and shoulder part can be easily deformed, whereby the contents remaining in the take-out part and shoulder part The present inventors have found that a product can be easily taken out and have completed the present invention.

  That is, in the tube container of the present invention, the outer periphery of the extraction port portion is provided with a concave groove in the screw portion and the shoulder portion, thereby facilitating deformation of the extraction port portion and the shoulder portion. It can be crushed flatly, and the contents remaining at the takeout port and shoulder are reduced as much as possible.

  The tube container of the present invention facilitates deformation of the take-out mouth and shoulder, enables the take-out mouth and shoulder to be flattened by finger pressure, and the contents remaining in the take-out mouth and shoulder are removed. In addition to the effect of reducing as much as possible, since there are few design restrictions and cost does not increase compared to conventional tube containers, it can be easily applied as a cosmetic container.

  The material that can be used for the tube container of the present invention is not particularly limited as long as the outer periphery of the take-out port portion can be provided with a concave groove in the screw portion and the shoulder portion, but a resin compound having excellent moldability Among them, polyethylene (PE), polypropylene (PP), vinyl chloride, and a multilayer obtained by combining them are preferable.

The shape of the concave groove that can be provided in the tube container of the present invention is not limited as long as it is concave, and the extraction opening and shoulder of the tube container are deformed by finger pressure or the like, and the extraction opening and shoulder are deformed. It is only necessary that the portion is flattened, the content space of the take-out port portion and the shoulder portion is reduced, and the contents existing there are eliminated. For example, V-shaped and U-shaped shapes can be used.

The size of the concave groove that can be provided in the tube container of the present invention is such that the extraction opening and the shoulder of the tube container are deformed by finger pressure or the like, the extraction opening and the shoulder become flat, and the extraction There is no particular limitation in the case where the internal space of the mouth and the shoulder is reduced and there is no restriction on the molding and design of the tube, but with respect to the width of the groove, 1/10 to 1 / 30 is preferable and 0.5 mm or more is preferable. Moreover, about the extraction opening part of the said tube, 1/5-1/20 of this extraction opening part diameter is preferable, and it is preferable that it is 0.5 mm or more. In addition, the depth of the groove is preferably 0.5 to 2 mm at the shoulder portion of the tube, and preferably from the thread valley of the screw portion to the height of the screw thread at the outlet portion of the tube.

A concave groove in the screw portion that can be provided in the tube container of the present invention and the flat portion of the screw portion in both directions rotated 90 degrees are parallel to the top of the screw thread with respect to each screw thread and expand to the lowest screw valley. It is possible.

  Hereinafter, the present invention will be specifically described with reference to examples. Note that the present invention is not limited to this.
