Abstract

The utility model provides an aluminum and plastic combined anti-counterfeiting bottle cap. The bottle cap comprises an outer cap, an aluminum outer sleeve, an inner cap, a connecting cylinder, an inner plug and buckles. The inner cap and the connecting cylinder are screwed. A sealing face A of the inner cap is in interference fit with a sealing face B of the connecting cylinder. The aluminum outer sleeve is provided with an indentation F. The connecting cylinder is provided with a U-shaped groove G. The inner cap and the connecting cylinder are arranged in the aluminum outer sleeve. The indentation F is wrapped on the edge of the U-shaped groove G. A gap is reserved between the indentation F and the U-shaped groove G so that relative movements can be formed. The inner plug is pressed into the connecting cylinder. A sealing face C of the inner plug is in interference fit with a sealing face D of the connecting cylinder. A sealing face E of the inner plug is in interference fit with the inner diameter of a bottle opening. According to the aluminum and plastic combined anti-counterfeiting bottle cap, the gap is reserved between the indentation of the aluminum outer sleeve and the U-shaped groove G of the connecting cylinder so that the relative movements can be formed; when the bottle cap is screwed again, the lower end of the inner cap presses the aluminum outer sleeve and the buckles to move downwards so that the aluminum cap can not deform; consequently, the reliability of products is greatly improved.

Description

A kind of plastic-aluminum is in conjunction with anti-fake bottle lid

Technical field

The utility model belongs to bottle cap packing technique field, relates in particular to a kind of plastic-aluminum in conjunction with anti-fake bottle lid.

Background technology

Aluminum plastic combined lid for liquor in background technology, after open bottle cover, repeatedly tighten, inner cap is by after aluminium lid compressive strain again, and the false proof part that can expose is too small, aluminium cannot all be exposed cover the printed words of " bottle cap is opened " outward, this antifalse effect that out of reach client needs.

Summary of the invention

The utility model provides a kind of plastic-aluminum in conjunction with anti-fake bottle lid, and when having solved the bottle cap in background technology and tightening after unlatching, inner cap is easily by the shortcoming of aluminium lid compressive strain.

The technical solution of the utility model is achieved in that a kind of plastic-aluminum is in conjunction with anti-fake bottle lid, comprise enclosing cover, aluminium overcoat, inner cap, disjunctor cylinder, interior plug and buckle, inner cap and disjunctor cylinder tighten, the sealing surface B interference fit of inner cap sealing surface A and disjunctor cylinder, aluminium puts outward and is provided with impression F, disjunctor cylinder is provided with U-shaped groove G, inner cap and disjunctor wound packages enter in aluminium overcoat, impression F is by U-shaped groove G bound edge, between impression F and U-shaped groove G, leave space, can form relative motion, interior plug is pressed in disjunctor cylinder, the sealing surface D interference fit of the sealing surface C of interior plug and disjunctor cylinder, the sealing surface E of interior plug and internal diameter of the bottleneck interference fit.

The beneficial effects of the utility model are: the utility model utilizes between aluminium overcoat impression and the U-shaped groove of disjunctor cylinder and leaves space, can form relative motion, after again lid being screwed, the lower side pressure of inner cap aluminium overcoat and buckle moves down, aluminium lid cannot be out of shape, greatly improve the reliability of product.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described: a kind of plastic-aluminum is in conjunction with anti-fake bottle lid, comprise enclosing cover 1, aluminium overcoat 2, inner cap 3, disjunctor cylinder 4, interior plug 5 and buckle 6, inner cap 3 tightens with disjunctor cylinder 4, the sealing surface B interference fit of the sealing surface A of inner cap 3 and disjunctor cylinder 4, aluminium overcoat 2 is provided with impression F, disjunctor cylinder 4 is provided with U-shaped groove G, inner cap 3 packs in aluminium overcoat 2 with disjunctor cylinder 4, impression F is by U-shaped groove G bound edge, between impression F and U-shaped groove G, leave space, can form relative motion, interior plug 5 is pressed in disjunctor cylinder 4, the sealing surface D interference fit of the sealing surface C of interior plug 5 and disjunctor cylinder 4, the sealing surface E of interior plug 5 and internal diameter of the bottleneck interference fit.

After bottle cap is pressed on bottleneck and opens, aluminium overcoat connects the some H of place and disconnects, deviate from from aluminium overcoat 2 inner cap 3 lower ends, due to gapped between aluminium overcoat impression F and the U-shaped groove G of disjunctor cylinder, can form relative motion, so after again lid being screwed, the lower side pressure of inner cap 3 aluminium overcoat 2 and buckle 6 moves down, aluminium lid cannot be out of shape, greatly improve the reliability of product.
