Novel water bottle opening combination with outer double rings and inner tight seal

Abstract

The invention discloses a novel water bottle opening combination with outer double rings and inner tight seal. The novel water bottle opening combination includes a bottle opening and a bottle cap, and the bottle opening covers the bottle cap. The bottle opening includes a supporting ring and an outer buckling ring, the outer edge of the top of the bottle opening is a sealing R arc surface, the top surface of the bottle opening is a sealing end surface, the inner edge of the top of the bottle opening is a guide arc surface, an inner sealing surface is arranged below the guide arc surface, andthe shape of the space enclosed by the inner sealing surface is an inverted circular platform. An open handle is arranged outside the bottle cap, a buckling position ring, an inner sealing R arc surface, a sealing bottom surface and an inner sealing plunger are arranged on the inner side of the bottle cap, and the inner sealing plunger protrudes downwards from the top of the bottle cap. When the bottle cap covers the bottle opening, the buckling position ring is connected with the outer buckling ring in a buckled mode, the inner sealing R arc surface is combined with the sealing R arc surface,the sealing bottom surface abuts against the sealing end surface, and the inner sealing plunger is plunged into the inner sealing surface to form circumferential surface seal. According to the novelwater bottle opening combination, the role of saving materials is played while sealing is ensured, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of plastic bottles, in particular to a novel combination of outer double rings and inner tightly sealed water bottle mouths. Background technique [0002] At present, the demand market for PET bottled water continues to grow. As a key component of water bottle packaging materials, PET bottles are also increasingly in demand. However, PET bottles are consumer consumables after all, and a large amount of use will cause problems such as waste and environmental pollution. The industry has been committed to reducing the weight of PET, so the lightweight of PET water bottles has been continuously developed. The bottle in the market, if it is a threaded structure, needs to be screwed in and threaded, at least three thread heights are required, so the height of the bottle cap greatly affects the material expenditure, and the thickness of the cap and the bottle mouth of the threaded structure must be It needs to be...

AI Technical Summary

Problems solved by technology

The bottle in the market, if it is a threaded structure, needs to be screwed in and threaded, at least three thread heights are required, so the height of the bottle cap greatly affects the material expenditure, and the thickness of the cap and the bottle mouth of the threaded structure must be It needs to be thickened, which cannot meet the requirements of saving materials. However, the traditional PET water bottle has a certain capacity, and the weight of the bottle is reduced to a certain extent, and the strength of the bottle will be weakened. functional defect
