Technical Field

The invention relates to a bottle cap of a bottle, which is a structure of the bottle cap with a sealing function.

Background

Since there are a lot of bottles currently on the market for various beverages such as fruit juice or carbonated beverages, it is necessary to seal the mouth of the bottle with a cap.

However, most of the bottles contain too much beverage, so that the whole bottle of beverage cannot be drunk by ordinary people at one time, and more or less residual beverage, even more than half bottle, is left in the bottle. Therefore, the user must screw the cap back to the mouth of the bottle, and when the user wants to drink the beverage again, the user must rotate the cap from the mouth of the bottle again, which is very troublesome.

Disclosure of Invention

In view of the disadvantages of the conventional bottle cap structure, the present invention has been developed through many researches and improvements to provide a bottle cap capable of temporarily and effectively sealing the mouth of a bottle, so that a user can effectively seal the mouth of the bottle without screwing the bottle cap back to the mouth of the bottle when the user opens the bottle cap and drinks a portion of the beverage.

The main structural design of the invention comprises a bottle cap which can be arranged on the mouth part of a bottle so as to be used for sealing the mouth part of the bottle, wherein the bottle cap comprises a body, a female thread is arranged in the body, and the female thread can be screwed on the mouth part of the bottle; the method is characterized in that:

the body is provided with a mouth part, a channel is arranged in the body and communicated with the cavity of the bottle, beverage can flow out of the bottle, and the valve body is arranged in the channel of the mouth part of the body, when the bottle is placed vertically, the valve body can seal the mouth part and the channel of the body to prevent the beverage from flowing out of the bottle, and can prevent the valve body from sealing the channel of the body when the bottle is in an inverted state, and the beverage can still continuously flow out of the bottle through the channel of the body.

The bottle cap structure with the sealing function is characterized in that the bottle cap is provided with a cushion body, and the cushion body is installed at the bottom of the mouth of the body and used for supporting and keeping the valve body in the channel of the body.

The bottle cap structure with the sealing function is characterized in that the cushion body is provided with an opening, and the opening is communicated with the mouth of the cushion body and the cavity of the bottle, so that the beverage can flow out of the bottle through the opening of the cushion body.

The bottle cap structure with the sealing function is characterized in that a valve seat capable of being embedded and matched with the valve body is arranged in the pad body.

The bottle cap structure with the sealing function is characterized in that the bottle cap is provided with a protruding body, and the protruding body is arranged in a channel of a mouth part of the body and can be used for embedding the valve body.

The bottle cap structure with the sealing function is characterized in that the bottle cap is provided with a rib, and the rib is arranged in a channel of the mouth part of the body and can support the protrusion.

The bottle cap structure with the sealing function is characterized in that the rib is provided with a gap which is communicated with the channel of the body, so that beverage can flow out of the channel of the body.

The bottle cap structure with the sealing function further comprises a sealing cover which can be arranged at the top of the mouth of the body so as to seal the mouth of the body when the beverage is not wanted to be drunk.

Detailed Description

The present invention relates to a bottle cap structure with sealing function, please refer to fig. 1 to 5, wherein the whole bottle cap structure with sealing function is mainly used for a bottle 10 which can be used for containing various beverages, and the bottle 10 generally comprises a cavity 11 which can be used for containing various beverages and has a mouth part 12 which can be used for filling beverages. The bottle cap 3 of the present invention is intended to be mounted or fixed on the mouth 12 of the bottle 10 so as to be used for screwing and sealing the mouth 12 of such a bottle 10.

With reference to fig. 2 to 6, this closure 3 comprises a body 30 of the cap, which is generally cylindrical or tubular and which is internally provided with a female thread 31 for screwing onto the mouth 12 of the bottle 10. The body 30 has a mouth 32, inside which a passage 33 is provided in communication with the cavity 11 of the bottle 10, allowing the beverage to flow out of the bottle 10 and also allowing the user to suck the beverage. The bottle 10 also has a sealing cap 50 that may be further mounted or secured to the top of the mouth 32 of the body 30 so that the mouth 32 of the body 30 may be sealed when drinking is not desired.

The body 30 also has a plug or pad 34 mounted or fixed to the bottom of the mouth 32 of the body 30, or disposed at the bottom of the channel 33 thereof, having an opening 35 in communication with the mouth 32 thereof and the cavity 11 of the bottle 10, such that beverage can still flow out of the bottle 10 through the opening 35 of the pad 34. The cushion 34 has a valve seat 36 for receiving a plug or valve body 40 to temporarily and effectively seal the mouth 12 of the bottle 10, as shown in fig. 2 and 5-6.

The body 30 is also provided with one or more ribs 37 at the top of the mouth 32 or at the top of the channel 33, and a channel or gap 38 between or adjacent to the ribs 37 to allow beverage to flow out of the bottle 10 through the gap 38 of the body 30. The rib 37 is provided with a top piece or protrusion 39 for abutting against the valve body 40, as shown in fig. 7, so as to prevent the valve body 40 from sealing the passage 33 of the body 30 when the bottle 10 is in an inverted state, and to allow the beverage to continuously flow out of the bottle 10 through the slit 38 of the body 30.

The mode of operation of the present invention, shown in fig. 7, allows a user to invert the bottle 10 to facilitate sucking the beverage. It should be noted that the protrusion 39 of the body 30 can abut against the valve body 40 to prevent the valve body 40 from sealing the passage 33 of the body 30, and the beverage can still continuously flow out of the bottle 10 through the slit 38 of the body 30. At this time, the valve body 40 is separated from the opening 35 of the pad body 34 and the valve seat 36.

Referring to fig. 2 and 5 to 6, when the bottle 10 is upright, the valve body 40 will fit the valve seat 36 of the pad 34 to seal the opening 35 of the pad 34 to prevent the beverage from flowing out of the bottle 10, and the valve body 40 can prevent the user's saliva from flowing back into the bottle 10, which also has the effect of improving hygiene.
