Description

Structural for backward flow protecting of a bottle inner straw

The present invention relates to a backflow prevention structure of an inner straw that is installed inside a beverage container including a bottle to prevent the beverage inside the container from flowing back to the inlet side, and more specifically, is coupled to the inlet end of the beverage container. In a straw for a conventional beverage container comprising a fixture, an inlet formed with an inlet hole to suck the contents of the beverage container, and a straw connecting each end of the fixture and the suction port, a central portion is cut at a predetermined point of the straw. A beverage container in which an elliptical backflow prevention part is inserted into which the formed silicone diaphragm is inserted so that the silicone diaphragm of the backflow prevention part is opened at the same time as the suction so that contents that can flow out through the suction member of the beverage container are automatically blocked. Of the internal straw backflow prevention structure .

In general, in order to allow young children who are in infancy and infants or elderly people who cannot drink on their own to drink the contents of the bottle by themselves, the nipple is fixed on the top of the bottle or a separate suction member that is easy to inhale is installed. A straw made of silicon is fixed to a fixture inserted between the bottle and the suction member.

Looking at the structure related to the conventional baby bottle and straw of such a structure based on Figures 1 and 2 as follows.

1 is a perspective view of a baby bottle equipped with a conventional straw, Figure 2 is an exploded perspective view of a conventional straw.

As shown, the conventional beverage container straw 1 is provided between the beverage container inlet side and the suction member at both ends of the straw 2 made of a transparent or semi-transparent straw made of silicone inside the beverage container body A. The inlet 4 and the inlet 4 is formed so that the inlet hole (4a) is formed so that the contents of the beverage container 3 and the inlet can be installed and fixed respectively.

The straw (2) is made of a silicon material with a predetermined elastic force to enable the movement of the suction port (4) to the inner corner of the bottle and transparent or so that the contents in the beverage container (A) can be checked It would be desirable to consist of translucent materials.

In addition, the suction port 4 is divided into an upper case 4 'and a lower case 4' ', and has a structure in which a weight 4b made of germanium is inserted therebetween, and the weight 4b The suction port 4 coupled to the end of the straw 2 by constant weight is configured to always face the bottom face regardless of the position of the beverage container.

The beverage container straw 1 of the above structure is fixed to one side end of the straw (2) is fixed between the upper end of the inlet side of the beverage container body (A) and the suction member fixing piece (6) The straw 2 is introduced into the beverage container body A, and the straw 2 is inserted into the beverage container body A so as to allow elastic flow.

The conventional beverage container straw 1 of this structure is provided with a structure or device for blocking the contents passing through the straw 2 when the contents remaining in the beverage container main body A are discharged to the outside by water pressure. It is pointed out that when the beverage container is upside down, the contents in the beverage container A are reversed through the straw 2 through the external suction member 5.

Therefore, the present invention was devised to solve the above-mentioned disadvantages and problems raised in the conventional yongyong dragon straw, the center portion at a certain portion of the silicone straw connecting the inlet and the upper fixture in which the contents of the beverage container is sucked in. The elliptical backflow prevention part is inserted into which the silicon diaphragm cut into a cross is inserted so that the silicone diaphragm opens only when the contents are inhaled through the suction member. It is an object of the present invention to provide a backflow prevention structure of a straw for a beverage container such that backflow is prevented through the suction member.
