Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a cap screwed onto the outer peripheral surface of a so-called tube container near the opening, such as toothpaste, paint, cream-type squeezed cosmetics, and the like. In order to prevent the quality change of the above, it is intended to improve the airtightness and at the same time to secure a breathing passage when an infant or the like accidentally swallows and clogs the throat.

[0002]

2. Description of the Related Art Various caps for tube containers have been developed in the past, but some caps such as toothpaste, cosmetics, paints, etc. are susceptible to oxidative deterioration or solidification due to contact with air. In order to allow sufficient sealing of the contents, a screw type screw is used which is screwed into a threaded portion provided on the outer peripheral surface of the tube container opening. However, an infant or the like may accidentally swallow it, causing it to clog the throat and block the respiratory tract. Therefore, the present inventors formed a boss portion that projects from the inner surface of the top end of the cap toward the inside of the opening of the tube container and closes the opening of the tube container as the cap is screwed in. We attempted to secure the airtightness of the contents and the respiratory passage when accidentally swallowed and stuffed into the throat by providing pores that open toward the mouth (single cap pore structure).

[0003]

The above-mentioned conventional general screw-type cap has a sufficient sealing property for contents, but secures a respiratory passage when it is accidentally swallowed and clogged in the throat. However, in the case of the single-cap pore structure that the present inventors have tried, it is considered that the contents in the tube container may block the above-mentioned pores due to the use over time. From the point of view of securing the passage, it is desired to improve it.

[0004]

Therefore, in the present invention, various problems in the above-mentioned prior art can be solved, a sufficient sealing property of the contents can be ensured, and the removed cap may be swallowed by accidental swallowing. It is designed to ensure a breathing passage when it is clogged. Specifically, the tube container is sealed inside the main body by being screwed into a threaded portion on the outer surface of the opening of the tube container. The present invention relates to a cap for a tube container, which has a screw-type inner cap for carrying out the above, and has an air hole formed between the inner cap and the main body.

Further, according to the present invention, there is provided a screw type inner cap inside the main body for screwing the threaded portion on the outer surface of the opening of the tube container to seal the tube container, and between the inner cap and the main body. Also relates to a cap for a tube container, which is characterized in that a plurality of ventilation holes are formed at intermittent portions in its circumferential direction. In this case, if the outer peripheral surface of the main body is knurled as necessary, the handleability thereof can be further improved and the functionality can be improved.

[0006]

When the inner cap of the cap according to the present invention is screwed into the threaded portion provided on the outer peripheral surface of the neck portion of the tube container and sequentially tightened, the tube container is completely sealed and the airtightness of the contents is improved. Retained. In addition, a vent is formed between the inner cap and the main body, and the inside of the inner cap is in contact with the mouth of the tube container during normal use. The ventilation hole is located, and there is no risk of the contents blocking the ventilation hole.

Further, even when an infant or the like accidentally swallows this cap when he / she removes the cap, and occludes it in his throat, the ventilation hole formed between the inner cap and the main body enables breathing. In this case, if a plurality of vent holes are formed between the inner cap and the main body at the intermittent locations in the circumferential direction, even if one vent hole is clogged, another vent hole This makes it possible to secure a respiratory passage. Further, when the outer peripheral surface of the main body is knurled, the turning operation when tightening or removing the cap becomes easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The concrete contents of the present invention will be described below with reference to the illustrated embodiments. In FIG. 4, T is a tube container, S is a shoulder portion, and N is a threaded portion on the outer peripheral surface (not shown). ) Indicates a neck portion, and C indicates a cap screwed onto the neck portion N. Further, as shown in FIGS. 1 to 3, the cap C is composed of a main body 1 and an inner cap 8 held inside the main body 1 by a connecting portion 3 with a constant gap portion 10 in the circumferential direction.

The outer peripheral surface of the main body 1 is provided with a knurled portion 2, and the top end portion 4 via the joint portion 3 is formed with a recessed portion 5 having its center portion recessed inward. Further, at the center of the recessed portion 5, there is provided a protruding portion 6 which is protruded inward of the cap 1 and at least the tip thereof is inserted into the opening of the neck portion N of the tube container T to close the opening. Has been formed. Further, the inner cap 8 has an inner diameter large enough to be fitted on the neck portion N, and has a threaded portion 9 on its inner peripheral surface for screwing into a threaded portion provided on the outer peripheral surface of the neck N. The inner cap 8 of the screw type is formed.

Further, in the above-mentioned connecting portion 3 where the inner cap 8 and the main body 1 are connected, a plurality of ventilation holes which allow sufficient ventilation through the gap portions 10 at the circumferentially intermittent portions thereof. 7 is formed. Although the ventilation holes 7 are formed at two symmetrical positions in the embodiment of the present application, they may be formed at three or more positions intermittently in the circumferential direction, or conversely, it is sufficient even if only one position is formed. It can exert its function.

[0011]

As described above, according to the present invention, the inside of the main body is screwed into the thread portion on the outer surface of the opening of the tube container,
Since it has a screw type inner cap for sealing the tube container and has a vent hole formed between the inner cap and the main body, it not only has a sufficient sealing property of the contents but also can be used. The contents also do not block the above-mentioned vents, so even if the removed cap is accidentally swallowed and gets stuck in the throat, the presence of such vents ensures a sufficient respiratory passage. Secured in.

Further, in this case, when a plurality of ventilation holes are formed at the circumferentially intermittent portions between the inner cap and the main body, even if one ventilation hole is clogged, The other ventilation holes ensure a breathing passage, which ensures even greater safety. Further, in this case, when the outer peripheral surface of the main body is knurled, the turning operation when tightening or removing the cap becomes easy.
