Description

A kind of plastic bottle closure and the packing plastic bottle containing this bottle cap

Technical field

The utility model belongs to a kind of packing container and its accessory, is related to a kind of improvement of container lid structure, more specifically , it is a kind of to realize closed plastic bottle closure and its Packaging Bottle using being bonded between closure member and lid platform.

Background technique

Currently, plastic bottles are widely used in the packaging of daily production as packing container, can be applied to such as contain Candy or drug etc. are filled, its capacity of this kind of bottle is smaller, can meet the outgoing carrying of people, allow its intrinsic energy in pocket or packet etc..

In daily life, for this Packaging Bottle, people require lid that can operate on the other hand, can by the finger of a hand Lai It opens lid or by cover closing, then, lid is often made into lid and closure member, is changed in conjunction with bottle body by sealing by lid Closing member opens or closes the outlet of bottle body.

In the lid that lid and closure member form, in general, lid and closure member are connected in one by interconnecting piece, make to close Part can realize by interconnecting piece relative to lid and overturn that still, the introducing of interconnecting piece makes closure member be difficult to seal lid again, Bottle tends not to meet candy or tablet must deposit in in the environment of outside air isolation.

Summary of the invention

A kind of packing plastic bottle the purpose of this utility model is to provide plastic bottle closure and containing this bottle cap, the plastics Bottle cap provides a kind of structure, can overcome the influence of interconnecting piece, closure member is enable to seal lid.

The plastic bottle closure of the utility model is realized by following scheme：

A kind of plastic bottle closure, closure member are linked into an integrated entity by interconnecting piece and lid, its main feature is that, lid portion inside is in top shape At there is platform, platform central is provided with through-hole, and the bulge loop that platform has lid top to constitute in periphery, bulge loop is in the radially company of being distributed with Connect and notch and pull notch, closure member is connected to connection breach by interconnecting piece, and pull indentations bottom, connection breach bottom, Interconnecting piece inner surface, closure member bottom side are concordant with platform surface, and closure member is sheet and match with platform, on closure member and It pulls the corresponding position of notch and is formed with tongue piece.

In this way, closure member can be overturn by interconnecting piece relative to lid when people pull tongue piece upwards, allow through-hole to expose with Just candy or tablet pass through；When people pull downwards tongue piece, closure member can also be rotated by interconnecting piece, allow tongue piece indentation to pull scarce Mouth can be bonded so as to closure member with platform, bulge loop, inner air and outer air can be prevented to exchange with platform, bulge loop fitting by closure member, risen To the effect of sealing.

It is preferred that intermediate position corresponding with through-hole is formed with the protrusion of annular on the inside of closure member in above scheme, dash forward It rises and coincide with through-hole surrounding.Then, when closure member is bonded with platform, bulge loop, protrusion will coincide with through-hole surrounding and will first lead to Hole closing, can play the effect for reinforcing sealing.

The utility model packing plastic bottle is realized by following scheme：

A kind of packing plastic bottle, its main feature is that, it include above-mentioned plastic bottle closure.

The plastic bottle closure of the invention and packing plastic bottle containing this bottle cap, pull indentations bottom, connection breach Bottom, interconnecting piece inner surface, closure member bottom side are in same level with platform surface, and then, closure member passes through connection It can guarantee that closure member bottom side can be bonded on the mesa surface after portion's rotation, meanwhile, closure member surrounding side is also and in bulge loop Side fits together, to can guarantee that plastic bottle closure has Packed performance.

The plastic bottle closure of the utility model and packing plastic bottle containing this bottle cap, when opening, as long as by finger by tongue Piece jacks up, then can be automatically cocked by closure member using the elasticity of interconnecting piece, and bottleneck is allowed to expose, can be by finger from outside when closing Closure member is depressed, closure member is made to be adjacent to platform, and make closure member surrounding squeeze into bulge loop, tongue piece indentation pull notch, then can evidence This fixed closed part and the closing for realizing bottle cap.

This plastic bottle closure and packing plastic bottle containing this bottle cap, lid, closure member and the connector of bottle cap can one Body injection molding, thus, structure is simple, and manufacturing cost is also more cheap, is adapted to promote and apply.

Detailed description of the invention

Fig. 1 is a kind of schematic diagram of specific embodiment structure of the utility model;

Fig. 2 is the schematic diagram of Fig. 1 packing plastic bottle opening state；

Fig. 3 is the schematic diagram of Fig. 1 packing plastic bottle closed state.

Specific embodiment

Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing：

Referring to Fig.1, in present embodiment, packing plastic bottle has plastic bottle closure 1, plastic bottle body 2 and tinfoil paper 3；Its In, plastic bottle closure 1 includes closure member 11, interconnecting piece 12 and lid 13, and closure member 11 is connected by interconnecting piece 12 and lid 13 One；It is formed with platform 13a in top inside lid 13, the center platform 13a is provided with through-hole 13b, and platform 13a has lid in periphery The bulge loop 13c that 13 tops are constituted, bulge loop 13c connection breach 13d and pull notch 13e in being radially distributed with;Closure member 11 by Interconnecting piece 12 is connected at connection breach 13d, and pull the bottom notch 13e, the bottom connection breach 13d, 12 inner surface of interconnecting piece, 11 bottom side of closure member with platform 13a flush；Closure member 11 is sheet and, closure member 11 inside consistent with planform shape Intermediate position corresponding with through-hole 13b is formed with the protrusion 11a of annular, and protrusion 11a can coincide with through-hole 13b surrounding, closure member Position corresponding with notch 13e is pulled is also formed with tongue piece 11b on 11.In this way, closure member 11 can be covered by the way that interconnecting piece 12 is opposite Body 13 rotates, and allows tongue piece 11b to enter and pulls notch 13e, meanwhile, protrusion 11a and through-hole 13b surrounding are coincide, and interconnecting piece 12 can be rolled over It is folded to be bonded closure member 11 with platform 13a, bulge loop 13c, it is common that through-hole 13b is prevented to carry out inner air and outer air exchange, preferably rise To the effect of sealed plastic bottle cap 1.

Referring to Fig.1, when packaging, it can be placed into candy or tablet in plastic bottle body 2, then, tinfoil paper 3 on pad, then by plastics Bottle cap 1 is tightened on plastic bottle body 2, tinfoil paper 3 can be adjacent in the mouthpiece of plastic bottle body 2 through high frequency, to guarantee plastics package Drying is in bottle before being not used.

Referring to Fig. 2 and Fig. 3, in use, tinfoil paper 3 can be removed first, then, operation can be held by plastic bottle by one every time Meanwhile being jacked up tongue piece 11b by its thumb, closure member 11 is overturn, allows through-hole 13b to be exposed for candy or tablet passes through, it can also It is depressed, then can be closed 13 through-hole 13b of lid by closure member 11 on the outside of closure member 11 by index finger.
