Description

[Detailed description of the invention] (Industrial application field) This invention relates to tube containers, especially synthetic resin containers with squeeze properties, and allows cream-like contents to be poured out without discomfort when extruded. It is intended to provide a certain tube container.

(Prior Art) When filling a commonly used tube container with cream-like contents, it is usual to fill the container from the tail end. In this case, since the creamy contents are viscous, a space is forced to be formed from the mouth of the container downward to the shoulder during filling. However, for example, sticky cream products such as cosmetics contain liquid substances such as water, oil, and alcohol, so these ingredients may be lost after production until they reach consumers. It exists as saturated vapor in the space near the shoulder, and a portion of it condenses and adheres to the inner wall. When consumers who have purchased these cosmetics open the tube container and start using it, the liquid mixture is squeezed out before the contents, and they often feel momentary discomfort. Sometimes they are mistaken for defective products with impurities mixed in.

(Problems to be solved by the invention) This invention was proposed with the aim of resolving the user's discomfort at the beginning of use. , it is an object of the present invention to provide a tube container structure in which the adhering liquid mixture is not extracted from the mouth part when the container is opened.

(Means for Solving the Problems) That is, this invention provides an inner stopper that has an inner cylinder that has a length that reaches inside the container from the shoulder of the main body and has a small hole at its tip. This relates to a tube container characterized in that a tube is attached to the mouth of the container.

(Function) In this invention, as described above, by providing an inner stopper with an inner cylinder that reaches the contents by poking into the space near the shoulder of the tube container where the liquid mixture is present. , it is possible to immediately pour out the contents without causing the liquid mixture to flow outside.

(Example) The details of this invention will be explained below with reference to the attached drawings. Fig. 1 is a perspective view showing an embodiment of this invention, with a part of the main part of a tube container 10 being a cutaway sectional view, and Fig. 2. is a longitudinal sectional view thereof. The tube container 10 shown in the embodiment is a squeezeable synthetic resin container made of polyethylene, ethylene vinyl acetate, nylon, vinylidene chloride, or a mixed resin or laminated resin of these.
is constructed so that it is fitted through a threaded portion 19 at the mouth of the main body.

An inner stopper 11 having a spout 13 is fitted into the mouth of the container, and a tip 1 is fitted inside the inner stopper 11.
An inner cylinder 12 having a small hole 14 with a diameter of about 0.5 to 2 mm is fitted into the inner cylinder 2a. This inner cylinder 12
has a length that reaches inward from the main body shoulder portion 10a, and has a length that reaches at least the filled contents c when the tube container is opened. Therefore, the tip 12a of the inner cylinder 12 is in constant contact with the contents C until it reaches the consumer, and the inner cylinder 12
Since the small hole 14 drilled at the tip of the inner cylinder is a small hole, the contents hardly flow into the inner cylinder from the small hole during filling, and the contents that directly touch the space L' in the inner cylinder 12 do not flow into the inner cylinder. has an extremely small surface area. For this reason, most of the components evaporated and separated from the contents C evaporate into the space L of the shoulder 10a to form saturated vapor, and some of it condenses on the inner wall of the shoulder of the container. This kind of phenomenon rarely occurs. Therefore, even when a consumer opens the container and starts using it, there is no condensation of such evaporated ingredients in the inner cylinder 12, which serves as a passage for extruding the contents, so that the creamy contents can be poured out immediately. becomes possible.

In addition, although the inner stopper 11 and the inner cylinder 12 are configured as separate bodies in the above embodiment, they may be formed integrally.

Furthermore, although the above embodiments have described a synthetic resin container with squeeze properties, this invention can also be applied to metal tubes using aluminum foil or the like.

(Effects) As described above, according to this invention, the inner plug is formed with an inner cylinder that has a length that reaches inward from the shoulder of the main body and has a small hole at its tip. ,
As mentioned above, there is almost no condensation of evaporated components within the inner cylinder, which serves as a passage for extruding the contents, and the discomfort often experienced due to liquid components flowing out when opening the package can be completely eliminated. Summer. This invention is extremely useful as a tube container, especially in fields such as cosmetics and foods that have a large psychological impact on users, and has a great effect.
