Gas guiding structure of container plug

The invention relates to a gas guiding structure of a container stopper, in particular to a container stopper made of artificial elastic material, which can be easily inserted into the opening of the container and formed into an opening tightly fixed to the container to achieve Good airtight effect.

The storage of liquids such as oil, vinegar, wine, beverages, fruit juices, etc., is carried out by filling the liquid with a container and then sealing it with a cover, which can be screwed with a spiral cover, or A plug having a diameter larger than the inner diameter of the opening of the container is fitted. Wherein, the screw cap is usually made of a metal material such as aluminum, and the screw cap has the advantages of low cost and good adhesion, but the screw cap gives a feeling of poor texture, and is sold. Products with higher prices such as wine and wine are obviously not applicable. In addition, when the plug is closed to the opening of the container, the plug can exhibit a high texture feeling, but when the container is filled with liquid such as oil, vinegar, wine, beverage, juice, etc., the container opening may have the above liquid remaining. And the slippery, or the gas in the container may form a pressure due to the decrease of the volume, so that the plug may not form a frictional force due to the liquid when the plug is in the opening of the container, or may not be positioned due to the pressure from the inside of the container. The container is open.

A stopper 9 made of a synthetic elastic material, as disclosed in Fig. 1, includes a plug body 91 and a head portion 92, and the plug body 91 and the head portion 92 can be separated or integrated. In the molding, the plug body 91 can be made into a cylindrical shape by using a material such as rubber, silicone rubber, plastic or foaming material, and in order to make the plug body 91 tightly seal the opening of the container, the diameter of the cylindrical plug body 91 can be Form an angle of inclination of 1 ° ~ 2 °, or the cylindrical plug body 91 The diameter is made slightly larger than the inner diameter of the opening of the container, and the diameter difference can be in the range of 3% to 8%, so that the stopper 9 made of the artificial elastic material can tightly seal the opening of the container. However, when the plug body 91 is inserted into the opening of the container, the stopper 9 still has problems such as rising, bouncing, and the like.

The applicants are specialized in the manufacture of the above-mentioned corks. So far, they have applied for dozens of patents. Among them, the Republic of China Announcement No. I238139 "Relief Cork" invention patent case can be as shown in Figure 2. The stopper 8 also includes a plug body 81 and a head portion 82. The outer surface of the plug body 81 is provided with one or more pressure relief grooves 83 extending through the top and bottom of the soft plug portion. The pressure relief groove 83 is formed between the two convex strips, and the pressure relief groove is also formed by the annular relief groove. The pressure relief groove 83 is formed by the outer surface of the soft plug portion or the outer surface of the plug body 81. 84. Thus, when the plug body 81 is placed in a container mouth position such as a glass bottle, the pressure enthalpy in the container such as the glass bottle can be released from the pressure release grooves 83, 84. According to the above, the pressure release groove 83 penetrates the top and bottom of the outer surface of the plug body 81. Therefore, when the container manufacturer's opening diameter is close to or greater than the upper limit tolerance, the pressure is located at the top of the outer surface of the plug body 81. With the groove 83, the container opening can not be tightly sealed, that is, the liquid contained in a small number of containers still oozes out from the pressure release groove 83 at the top of the plug body 81, forming a leak.

In addition, the applicant applied for the invention patent of the "Pneumatic plug" patent of the Republic of China Announcement No. I357876 and the new patent case of the "Cork Structure" of the Republic of China Announcement No. M372834, which can be as shown in Figure 3. The stopper 7 is composed of a plug body 71 and a head portion 72. The outer surface of the plug body 71 is provided with more than one air guiding groove 73. The air guiding groove 73 can be recessed in the plug body 71. a groove of the outer peripheral wall or a micro convex ridge formed on the outer peripheral wall of the plug body 71. The bottom portion of the plug body 71 forms a guide portion 71a. The upper portion of the plug body 71 forms a closed portion 71b. The diameter of the closed portion 71b is greater than about 3% to 8% of the inner diameter of the opening of the container. The air groove 73 extends upward from one of the corner portions 71a of the bottom of the plug body 71 to a middle portion of the closing portion 71b. Thus, the plug body 71 has a closed portion 71b having a circular cross section. When the plug body 71 of the stopper 7 is placed in a container mouth position such as a glass bottle, the pressure in the container such as the glass bottle 遂 It can be partially released by the air guiding groove 73. According to the above, the upper end of the air guiding groove 73 is only at a middle position of the closing portion 71b. Therefore, the effective distance of the opening 71 of the sealing body 71 can be closed, and only the upper half of the closing portion 71b is located. When the plug body 71 is inserted into the mouth of the container such as a glass bottle, there is still leakage.

In order to improve the above-mentioned deficiency, the applicant has attempted to increase the difference between the diameter of the closing portion 71b and the opening diameter of the opening of the container so that the plug body 71 is tightly sealed to the opening of the container. Thus, although the stopper 7 can improve the leakage, the plug 71 will cause the excess deformable elastic material to push toward the head 72 of the stopper 7 due to the increase in diameter, and form a stopper. a radially projecting projection that will cause the head 72 of the stopper 7 to be in insecure contact with the open top end of the container, such that a gap is formed between the head 72 and the open top end of the container; When the plug body 71 of the stopper 7 is taken out from the opening of the container, the plug body 71 is excessively tightly sealed, and the removal of the plug body 71 becomes difficult and difficult.

In view of the above, the present invention further provides a gas guiding structure of a container plug, which can insert a part of the gas in the container when the container is inserted into the opening of the container, so that the container plug can be positioned at the opening of the container, The opening of the container can be closed securely, and the container plug can be easily removed when it is removed from the opening of the container.
