Problems solved by technology

If the bottle caps are all made of non-plastic materials, such as metal materials, it is difficult to ensure the tightness between the metal and the glass wine bottle, so plastic bottle caps must be used, but the problem of contact between the plastic and the wine liquid needs to be solved

Embodiment Construction

[0020] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0021] Such as figure 1 As shown, the preferred embodiment of the wine bottle cap of the present invention includes an upper cover 1, a middle section 2 and an inner plug 3, and the middle section 2 has a connected upper mouth 21 and a lower mouth 22 set on the wine bottle mouth , the outer wall of the upper mouth 21 has an external thread, the upper cover 1 has an inner thread matched with the outer thread of the upper mouth 21, the inner plug 3 is a hollow ring, the inner plug 3 is wrapped with at least one layer of metal foil paper 4, and the inner plug 3 There is a metal tube 5 that can move in the direction of the bottle to puncture or push away the meta...

Abstract

The invention relates to a bottle cap which comprises an upper cap body, a middle section and an inner plug. The middle section is provided with a lower opening portion communicated with an upper opening portion and installed on a bottle opening portion in a sleeved mode, the outer wall of the upper opening portion is provided with external threads, the upper cap body is provided with internal threads matched with the external threads of the upper opening portion, the inner plug is in the shape of a hollow ring, the outer portion of the inner plug is wrapped by at least one layer of metal foil paper, a metal pipe which can move in the direction of the inner portion of a bottle to puncture or jack the metal foil paper is arranged in the inner plug, the inner plug comprises a constraint section and a seal section, the inner diameter of the constraint section is matched with the outer diameter of the metal pipe, and the outer diameter of the seal section is matched with the inner diameter of the bottle opening. The bottle cap is novel in conception and easy to manufacture, avoids the possibility that liquor makes contact with plastic when the liquor is stored, and therefore plasticizers in the plastic bottle cap are prevented from dissolving into the liquor; through the metal pipe, the contact time and the contact frequency of the liquor and the plastic are reduced when the bottle cap is used, tiny plasticizers enter the liquor, and therefore the plasticizers are controlled in a very low safety range.

Description

technical field [0001] The invention relates to the technical field of bottle caps, in particular to a wine bottle cap. Background technique [0002] The content of plasticizer in liquor is related to the amount and frequency of residence time of liquor in plastic pipes and containers. The plasticizers in liquor products belong to specific migration, mainly originating from plastic wine barrels, plastic wine delivery pipes, latex pipes in and out of wine pumps, plastic cloth for sealing wine tanks, plastic inner covers of finished wine, plastic bag packaging of finished wine, finished wine Plastic bottle packaging, finished wine plastic barrel packaging, etc. After the outbreak of the liquor plasticizer incident, in order to avoid the plasticizer in the liquor, various wineries have begun to reduce the contact opportunities between liquor and plastic. Because the combination of plastic and glass can improve the sealing performance, in the prior art, most of the bottle caps...
