Description
Technical Field
The invention relates to sealing and anti-theft opening of a container, in particular to sealing and anti-theft opening of a glass bottle, and particularly relates to an anti-theft opening bottle stopper with a pumping-pressing type seal, which is suitable for a long-neck glass bottle with a shoulder.
Background
The bottle stopper utilizes the interference fit of cock body and bottleneck, prevents that liquid from overflowing from the bottle. The common bottle stopper comprises a rubber plug and a wooden plug. The wooden plug is mostly used for wine packaging, and a special tool is needed for opening when the wooden plug is used. Due to the characteristics of the wooden plug, chipping and breaking are easy to generate in the opening process, and consumption experience is influenced. Meanwhile, when the wooden plug taken out is reused, the protection effect on the liquid in the bottle is greatly weakened, and quality damage or waste is caused. The anti-tamper function of wine product package is also an essential function for ensuring the safety of the product.
Various solutions have been proposed to address these problems of wine packaging use.
Patent 1 (a bottle stopper with an opening device arranged in red wine, CN 20162120592.7, 2017.05.03) discloses a bottle stopper with an opening device for red wine, wherein the whole bottle stopper is of a bracket structure, the bracket is fixed outside a bottle neck, a sealing stopper body is connected to the bracket, and a handle structure is arranged on the sealing stopper body, so that the defects that a traditional wooden stopper is easy to break to generate scraps and the like are overcome, the sealing, quick opening and reuse of a wine bottle are realized, but a rotating shaft, the stopper body, a sleeve and a buffer body are in a sliding fit state to influence the sealing performance of the bottle stopper, and meanwhile, the device cannot realize the function of displaying/opening the bottle stopper.
Patent 2 (a wine bottle stopper that can open and seal fast, 201610549262.2, 2016.09.28) invented a wine bottle stopper that can open and seal fast, adopted plunger type and inflation bag composite structure, relied on the screw-in of plunger to extrude the inflation bag, realized the sealing of bottleneck, solved the liquid in the bottle after opening the problem of preserving again. However, the metal protective head adopted at the end part of the bottle can not prevent the liquid in the bottle from contacting with the expansion bag and the bracket, because the protective head is in clearance fit with the inner diameter of the bottle, otherwise, the bottle plug can not be put into or taken out of the bottle mouth.
Patent 3 (an anti-counterfeiting wine bottle and an anti-counterfeiting method thereof, CN201710057210.8, 2017.05.10) invents an anti-counterfeiting bottle cap structure composed of a bottle cap, a screw rod and a bottle plug, wherein the bottle cap and the bottle plug are connected by the screw rod, and the bottle cap is rotated to realize the rotation and the lifting of the bottle plug and simultaneously destroy the anti-counterfeiting support at the top of the bottle plug. This patent simple structure, but bottle lid, screw rod and bottle plug form integral type structure, and the bottle lid supporter does not have outside bearing structure when the bottle lid is rotatory, leads to bottle lid, screw rod and bottle plug to rotate simultaneously, can't break anti-fake support border, influences anti-fake effect.
Although designers have adopted various approaches to the sealing of red wine bottle type packages, various deficiencies exist.
