Abstract

A plastic packaging container comprises a barrel cover and a barrel body. A second projection and a fourth projection are arranged on the inner side surface of the barrel cover; a long thin wall is arranged between the second projection and the fourth projection; a plurality of holes are formed on the long thin wall along the periphery of the barrel cover; a tear ring is arranged below the long thin wall; a tear block is arranged on the tear ring; a short thin wall adjacent to the tear block is arranged on the tear ring; a first projection matched with the second projection on the barrel cover is arranged at the mouth of the barrel body; a third projection, a large projection and a small projection are arranged below the first projection on the barrel body; the third projection is matched with the fourth projection on the barrel cover; the small projection is positioned on the edge of the large projection; the lower end edge of the tear ring is blocked by the small and the large projections; and at least two outwards projecting tongue-shaped objects are arranged on the inner side of the top of the barrel cover. The plastic packaging container has the advantages of good seal property, simple and safe opening mode and anti-counterfeiting function.

Description

Plastic packaging containers

Technical field

The utility model relates to a kind of plastic packaging containers, is mainly used in to be fit to the packing that plastic material carries out packaged products, belongs to packaging field.

Background technology

Be used for the plastic packaging containers that the packing of product is used at present, be mostly to combine by staving and bung.Have the projection or the groove that can cooperatively interact between staving and the bung, can closely cooperate mutually between these projectioies or the groove, be difficult between staving and the bung separately thereby make, thereby guaranteed the leak tightness of plastic packaging containers, but thisly closely cooperate and cause lid to be difficult to take off, give and take packing container apart and bring difficulty from staving.

Summary of the invention

The purpose of this utility model is the defective that overcomes prior art, a kind of unlatching easy to use, easy is provided, has anti-fraud functional plastic packaging containers.

The technical scheme that realizes above-mentioned purpose is: a kind of plastic packaging containers, comprise bung and staving, the medial surface of bung has second projection and the 4th projection, between second projection of bung inboard and the 4th projection, has the thin long thin-walled of wall thickness, have a plurality of holes at long thin-walled place along one week of bung, long thin-walled below has the circle of tearing, tear and tear piece on the circle, have on the circle and tear the adjacent short thin-walled of piece tearing, the staving oral area has first projection that matches with second projection on the bung, below first projection on the staving, the 3rd projection is arranged, big projection and small embossment, the 3rd the 4th projection protruding and on the bung matches, small embossment is torn the lower edge of circle and is blocked by small embossment and big projection on the edge of big projection.

The bung inside top has at least two tongues to outer lug.

After adopting technique scheme, when the lid bung, bung in-to-in second projection and the 4th projection catch on first projection and the 3rd projection of bung respectively.When needs are opened bung, only need firmly be pulled outwardly the piece of tearing on the bung, local just the becoming along the adjacent a plurality of holes of long thin-walled of bung torn track, and bung is torn the 4th projection of track below and is torn circle and is torn along tearing track.Bung is torn tearing after circle and the 4th projection torn of track below, and bung is inner to also have second first projection protruding and bung to match, and so just can guarantee that bung is fixed on to be not easy on the bung to come off.Therefore the inside top of bung catches tongue just can open bung easily when uncapping owing to the tongue that has to outer lug.Tear tear circle before since lid tear circle by one the circle projection block, must destroy when opening bung and tear circle, so this packing container has anti-fake effect again.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Shown in Fig. 1～9, a kind of plastic packaging containers, comprise bung 1 and staving 2, the medial surface of bung 1 has the second protruding 1-1 and the 4th protruding 1-2, between the second protruding 1-1 of bung 1 inboard and the 4th protruding 1-2, has the thin long thin-walled 1-3 of wall thickness, have a plurality of hole 1-4 at long thin-walled 1-3 place along 1 one weeks of bung, long thin-walled 1-3 below has tears circle 1-6, tear on the circle 1-6 and tear piece 1-7, have on the 1-6 and tear the adjacent short thin-walled 1-8 of piece 1-7 tearing circle, staving 2 oral areas have the first protruding 2-1 that matches with the second protruding 1-1 on the bung 1, below the first protruding 2-1 on the staving 2, the 3rd protruding 2-2 is arranged, big protruding 2-3 and small embossment 2-4, the 3rd protruding 2-2 matches with the 4th protruding 1-2 on the bung 1, small embossment 2-4 tears the lower edge of circle 1-6 and is blocked by small embossment 2-4 and big protruding 2-3 on the edge of big protruding 2-3.

As shown in Figure 1, bung 1 inside top has at least two tongue 1-5 to outer lug.

Principle of work of the present utility model is as follows:

Shown in Fig. 1～9, when not opening bung 1, the bung 1 in-to-in second protruding 1-1 catches on the first protruding 2-1 of staving 2 oral areas, and bung 1 in-to-in the 4th protruding 1-2 catches on the 3rd protruding 2-2 of staving 2 oral areas simultaneously.When needs are opened bung 1, only need firmly be pulled outwardly and tear piece 1-7 on the bung 1, local just the becoming along the adjacent a plurality of hole 1-4 of long thin-walled 1-3 of bung 1 torn track, the 4th protruding 1-2 that tears the track below of bung 1 and tear and enclose 1-6 and be torn along tearing track.After bung 1 was torn tearing circle 1-6 and the 4th protruding 1-2 and being torn of track below, bung 1 is inner to also have the first protruding 2-1 of the second protruding 1-1 and staving 2 oral areas to match, and so just can guarantee that bung 1 is fixed on staving 2 oral areas to be not easy to come off.Therefore the inside top of bung 1 only need catch tongue 1-5 just can open bung 1 easily when opening bung 1 owing to the tongue 1-5 that has to outer lug.When tearing circle 1-6 owing to tear or overturn, must destroy short thin-walled 1-8, simultaneously tear tear circle 1-6 before, the circle 1-6 that tears of bung 1 is blocked by big protruding 2-3 and small embossment 2-4, must destroy when therefore opening bung 1 and tear circle 1-6, so this packing container has anti-fake effect.

Plastic packaging containers of the present utility model has good airproof performance, the simple and safe advantage of opening ways.
