The present invention relates to a synthetic resin bottle cap that can be used as a straw in a beverage container for beverages such as PET bottles. More specifically, a straw-shaped straw installation portion formed in the upper end of the main body, a groove-shaped cutout portion, a protruding blotting portion and a layered sealing means seated at the inlet of the beverage container, The present invention relates to a plastic bottle cap, which can be used for straw, in which the hygienic state of the beverage container lid is kept clean from the foreign matter in the air and the airtight condition of the beverage container and the bottle cap is maintained continuously even at high temperature and high pressure sterilization process. .

In general, synthetic beverage containers have been applied in various technical fields as advantages such as cost reduction in the manufacturing process and convenience of consumer's use of the material itself have gained effectiveness in the company's production activities. In particular, in the beverage containers of beverages, as well as convenience for consumers to drink beverages, technologies for further improving the hygiene state inside and outside have been sought in various forms.

For example, Republic of Korea Patent Publication No. 79668 (October 19, 2002, hereinafter referred to as 'prior art 1') and No. 40421 (published on May 12, 2004, hereinafter referred to as 'prior art 2' The techniques disclosed in the above) may be mentioned. Looking at the contents disclosed in the prior art in more detail it can be seen that the following facts.

First, the technique disclosed in the prior art 1 relates to a bottle cap provided with a straw support. This can be roughly divided into a first forming body and a second forming body, as shown in the specification and the accompanying drawings, wherein the first forming body is inserted into an insertion hole of the main body and operated up and down, and a bent part of the main body. It includes a stopper coupled to, the operating portion is configured in the form accommodated in the stopper, the second forming body is formed in the beverage container as a straw formed with the straw is formed in the lower container is configured to receive the first forming body.

According to the prior art 1 as described above, the sealing property of the beverage container containing the beverage is guaranteed, so that the effect of preventing the leakage of the beverage due to the subsidiary environment is expected. At the same time, however, this requires not only a considerable suction force when the user wants to drink a beverage, but also causes inconveniences of pressing the torso of the beverage container by hand. In particular, due to the complicated structure divided into the first and second formations, the manufacturing process can not only solve the problem of costly production due to the large number of processes.

On the other hand, looking at the contents disclosed through the prior art 2, it can be seen that the bottle cap is configured to be inserted into the straw. That is, in the bottle cap consisting of an upper surface portion and a side portion, a space recessed in a predetermined size is formed in the upper surface portion, and a cut film formed with a pull ring is formed in the space by a cut portion, and when the pull ring is pulled, it is cut off. The membrane is removed to form the straw mounting portion, and the straw is configured so that the straw can be used. Incidentally, the upper surface portion discloses a form further including a seal member for protecting the recessed space.

In the case of the bottle cap according to the prior art 2, by significantly simplifying the configuration compared to the prior art 1, there are some advantages, such as to solve the problems associated with the production cost in the manufacturing process. However, the bottle cap according to the prior art 2 is bound to have a fatal problem in hygiene from the external shape. That is, if the user is inadvertently spilling the drink while using the straw as the space formed in the upper surface is formed in a recessed form, it is not easy to remove the beverage flowing into the corner of the recessed space. This, in turn, creates an environment of bacteria that is harmful to the human body, as well as contamination by foreign matter such as dust in the atmosphere. On the other hand, it can be said that the sealing member compensates for the hygiene problem caused by the shape of the space, but the hygiene problem of the lid still remains because only the removal of the sealing member must be preceded for the use of the straw. It cannot be solved.

In addition, according to the related art 2, since the bottle inlet containing the beverage is formed by sealing the bottle inlet protruding from the upper surface portion into the bottle inlet, the application range of the technique has a very limited problem. . In other words, due to the fragility of the incision that partitions the cutting membrane integrated with the pull ring is unable to withstand the heat pressure of the sterilization process. This, after all, does not solve the problem that the bottle cap according to the prior art 2 cannot be used for products having a neutral hydrogen ion concentration that must undergo sterilization for preservation of the beverage product.

The present invention has been made to solve the above problems of the prior art, an object of the present invention is provided with a straw-shaped straw installation portion cut from the pressurization of the straw on the upper end of the body of the bottle cap, the groove-shaped incision is the upper end of the body It is formed to the inside of the beautiful appearance, as well as to provide a plastic bottle cap that can be used as a straw that can keep the sanitary state of the beverage container lid clean from foreign substances in the atmosphere.

In addition, the beverage container and the bottle lid is mounted so that the sealing means of the layered structure seated at the inlet of the beverage container by the pressure-sensitive portion formed to protrude downward on the inner upper surface of the bottle cap, so that the beverage container containing the beverage of low hydrogen ion concentration Another object of the present invention is to provide a straw-capable plastic bottle cap that can maintain the airtightness between the beverage container and the bottle cap even under the high temperature and high pressure sterilization process performed with the bottle cap mounted at the inlet. .

A straw-capable synthetic resin bottle cap according to the present invention for achieving the above object is from the main body is formed with a spiral guide means to the inside of the side end portion to be mounted to the inlet of the beverage container, from a plurality of joints provided at the lower end of the main body A fixed member having an anti-rotation means formed integrally and restricting rotation in a specific direction, a straw installation portion formed at an upper end of the main body so as to be cut by pressing the straw, and for maintaining the airtightness of the beverage container and the main body; The main body so as to improve the airtightness of the sealing means and the beverage container by pressing the sealing means seated in the inlet of the beverage container and the sealing means in contact with the beverage container consists of a layer of paper and foil layer between the PE layer. An inner upper surface of the pressurizing portion protruding toward the sealing means is formed.

And the straw mounting portion has a cutout portion having an inner surface of a yaw shape and a flat outer surface and a rotating side tip surface inclined downward toward the center side, and a part of the cutout portion, from the blotting portion to the center side of the main body. A cutout portion formed in a groove shape is included on the inner upper surface of the main body so that the main body is cut out from the main body and rotated.

In more detail, the sterilization process and the beverage container to withstand the sterilization process are selected according to the hydrogen ion concentration-PH value of the beverage.
In other words, coffee or sikhye, which has a neutral PH value, are sterilized at a high temperature and high pressure, which is sterilized with hot water or steam of 100 ° C. or higher and approximately 121 ° C. for 15 minutes in a sealed container. The process is applied and containers such as cans, sterilization bottles and pouches are used to withstand this retort sterilization process.
In addition, pasteurizer sterilization is applied to juices and carbonated beverages with low PH level, which are usually sterilized only with hot water of 60 to 90 ° C. while the beverage container is opened. Containers suitable for the process, such as bottles, PET and cans filled with nitrogen, are used.
Therefore, the retort sterilization process was not applicable to the container used for the pasteurizer sterilization process, especially PET bottle, which is a bottle of the beverage bottle (2) and the lid of the bottle by high pressure when the retort sterilization process is executed while the PET bottle is closed. This is because the airtight breakage, precisely because the fine hole is formed between the upper surface of the beverage container 2 and the sealing means 30, the airtight is broken.
Therefore, the present invention pressurizes the sealing means 30 seated on the upper surface of the inlet of the beverage container 2, the pressure-sensitive portion 14 protruding downward on the inner upper surface of the main body 10 so that the PET bottle can withstand the retort sterilization process.
