Description

Baby bottle structure having straw {Baby bottle structure having straw}

The present invention relates to a structure of a baby bottle having a nipple, and more particularly, to a structure of a baby bottle having a nipple that prevents backflow caused by a difference in temperature and air pressure between the inside and outside of the bottle when the bottle containing milk is used.

In general, a nursing bottle may be designed in various forms, but it is composed of a container capable of accommodating milk and a cover capable of preventing the contained milk from spilling to the outside. In order to do this, most of the straws are provided in the cover. In addition, it may be provided with a lid covering the cover equipped with a straw for the convenience of storage during movement.

In common with these baby bottles, when infants eat milk, the milk inside the bottle is discharged and a low pressure is formed inside the container in proportion to the corresponding volume, so the liquid inside the container cannot be easily discharged due to the pressure difference. In this case, since infants have difficulty in eating milk, an air inflow and outflow structure such as an air hole is usually provided to allow air to flow in from the outside in order to relieve this low pressure state.

In addition, since a high pressure is formed by the milk in the container filled with warm milk inside the bottle, there is a risk that the liquid inside is suddenly ejected through the straw if there is no air inlet and outlet structure as described above, and furthermore, the container and cover are screwed. In the fastening structure such as coupling, the internal volume of the baby bottle is reduced during the screw coupling process, and the reduced volume is required to be discharged to the outside, so the internal liquid flows back through the straw during the fastening process, which solves these overall problems. In order to solve this problem, a baby bottle with a straw used by infants is necessarily provided with an air inflow and outflow structure.

For example, Republic of Korea Utility Model Registration No. 20-0433734 (20061206) 『Pressure parallel valve for a beverage container having a straw』 discloses a pressure parallel valve coupled to a lid, that is, the above-mentioned air inflow and outflow structure. A function that can release the high pressure and low pressure conditions is proposed with a parallel valve, but since the structure is provided on the cover separately from the straw, the product structure is complicated as a result, and the number of parts increases, resulting in convenience such as assembly and cleaning. There are problems of deterioration and difficult maintenance, and in particular, when the inside of the baby bottle is in a high-pressure state, the user needs to press the valve separately. In the conventional baby bottle as described above, when warm water or milk is stored inside the container, high pressure is formed by the vapor of the contents in the container, so when the straw or opening is opened, the liquid inside is suddenly ejected. , In the case of drinking milk inside the straw, there is a problem in that the liquid inside the container is not easily discharged due to the pressure difference because the milk is discharged and a low pressure state is formed inside the baby bottle in proportion to the corresponding volume.

7 of the accompanying drawings is an enlarged view of a main part showing a fourth application example of a valve member of a baby bottle structure having a nipple according to a preferred embodiment of the present invention.

The structure of the baby bottle with the nipple according to the present invention according to this drawing embodies the same basic structure of the first embodiment described above.

That is, the baby bottle structure having a teat according to the present invention according to the drawings is divided into a container member 10, a nipple member 20, and a clamping member 30, but the top is open like a container such as a milk bottle, and the bottom As a general container in which a receiving space (sign omitted) is formed, but a bottom (sign omitted) is formed, in this embodiment, the upper open end has a narrower diameter than the container body. And, the first plate surface 22 is formed inside the circular plate body portion 21, and a stepped portion 27 bent at right angles upward is formed on the inside of the plate body portion 21, and the stepped portion 27 has The insertion groove 28 is formed in a ring shape, and forms a circle with a smaller diameter than the plate body portion 21 in the horizontal direction from the top of the stepped portion 27, but the upper surface is an inclined curved surface 23.

Although this Gore-Tex part 37 uses the name of a specific inventor, it is a widely known technology. This Gore-Tex part 37 has the principle of Gore-Tex having the characteristic of surface tension that allows air to pass through the outer side of the fastening member 30 at a minute interval of about 0.05 mm but does not allow liquid flow to pass through. For reference, the Gore-Tex part 37 of the present invention is micropores having a principle of generating countless micropores when Teflon is heated and stretched, and the name of Wilbert L. Gore, a former engineer at DuPont, was used. Because of the holes on the surface of Teflon resin, which has extremely low reactivity, Gore-Tex has become a fiber and resin with the opposite function of waterproof and breathable. Water cannot pass through these holes due to surface tension and other reasons.
