Description

Be prone to the plastic packaging containers of unlatching

Technical field

The utility model relates to a kind of plastic packaging containers of easy unlatching, belongs to the plastic packaging containers field.

Background technology

At present, the opening ways of the sealed plastic packing container under the prior art all need could be opened the bung of bucket by instruments such as spanner, cutters, even free-hand long time and the energy of also needing could be opened bung.By instrument the time, the time regular meeting safety misadventure of hurting sb.'s feelings, so just can bring the very negative effect of inconvenience to the normal management of enterprise.

Summary of the invention

The purpose of the utility model is the defective that overcomes prior art, and a kind of plastic packaging containers of easy to use, easy unlatching is provided.

The technical scheme that realizes the utility model purpose is: a kind of plastic packaging containers of easy unlatching; It comprises bung and staving, and bung comprises and be positioned at tearing circle, tearing the big plane in outer wall, top plan, inwall and center of circle top of bung bottom, tears to have the mouth of unlatching on the circle; Tear between circle and the outer wall and have first thin-walled; Be provided with first clasp in the inboard of outer wall, have some grooves that can break off first clasp on the outer wall, the top of staving is provided with ora terminalis; Also be provided with second clasp that cooperates with first clasp on the staving; This second clasp is positioned at the below of ora terminalis, and the bung inboard is provided with the convexity that cooperates with ora terminalis, and this convexity is between outer wall and inwall.

Further, described outer wall inboard is provided with sealed muscle, and the sealing muscle is positioned at the top of first clasp.

Further, the cross-sectional plane of described sealed muscle is a triangle.

Further, the outer wall of bung is provided with second thin-walled, and the groove that this second thin-walled will break off first clasp from the outside of bung outer wall is sealed, and the wall thickness of zone except that first thin-walled that the second thin-wall wall ratio is closed on will approach.

After having adopted technique scheme, firmly push down bung when bung is placed on the staving top, first clasp of bung and second clasp of staving end fasten each other at this moment.When second clasp of first clasp of bung and staving end fastens each other; Sealed muscle closed contact on first medial surface of the lateral surface of staving ora terminalis and bung outer wall; The protruding closed contact that second medial surface of staving top ora terminalis and bung top plan are inboard is so form sealing through closely cooperating of contact surface between bung and the staving.Sealed muscle on first medial surface of outer wall can increase sealing property.The junction of tearing circle and outer wall has first thin-walled, and this first thin-walled forms tears track.When needs are opened bung; To tear circle through the unlatching mouth of tearing circle tears; Forming nick shaped at the groove place at the bottom margin that tears first clasp of tearing circle back bung breaks off; This moment bung second clasp of first clasp and staving end between tightening force will be weakened, so can be free-hand firmly first clasp of bung, second clasp from staving be pulled open, so just can bung be opened very easily.Because the unlatching of this kind bung does not need by instrument, therefore can realize the easy open function of packing container.When on the outer wall at bung second thin-walled being set; The groove that this second thin-walled will break off first clasp from the outside of outer wall is sealed; Thereby it is inner to prevent that extraneous foreign material from getting into lid through groove; Because the wall thickness of zone except that first thin-walled that the zone that the second thin-wall wall ratio is closed on is closed on be not so the easy open function of bung can receive obvious weakening.

The specific embodiment

For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation below according to specific embodiment and combine accompanying drawing.

Shown in Fig. 1 ~ 5, a kind of plastic packaging containers of easy unlatching, it comprises bung 1 and staving 2; Bung 1 comprises the big plane 7 in outer wall 4, top plan 5, inwall 6 and center of enclosing 3, tearing circle 3 tops of tearing that is positioned at bung 1 bottom; Tear circle and have on 3 and open mouthfuls 10, tear between circle 3 and the outer wall 4 and have first thin-walled 9, be provided with first clasp 8 in the inboard of outer wall 4; Have some grooves 11 that can break off first clasp 8 on the outer wall 4; The top of staving 2 is provided with ora terminalis 13, also is provided with second clasp 14 that cooperates with first clasp 8 on the staving 2, and this second clasp 14 is positioned at the below of ora terminalis 13; Bung 1 inboard is provided with the convexity 12 that cooperates with ora terminalis 13, and this convexity 12 is between outer wall 4 and inwall 6.

As shown in Figure 4, described outer wall 4 inboards are provided with sealed muscle 18, and sealing muscle 18 is positioned at the top of first clasp 8.The cross-sectional plane of described sealed muscle 18 is a triangle.

As shown in Figure 5, the outer wall 4 of bung 1 is provided with the groove 11 that second thin-walled, 19, the second thin-walleds 19 will break off first clasp 8 from the outside of outer wall 4 and seals the wall thickness of the zone that the wall ratio of second thin-walled 19 is closed on except that first thin-walled 9.

The principle of work of the utility model is following:

Firmly push down bung 1 when bung 1 is placed on staving 2 tops, first clasp 8 of bung 1 and second clasp 14 of staving 2 ends fasten each other at this moment.When second clasp 14 of first clasp 8 of bung 1 and staving 2 ends fastens each other; Sealed muscle 18 closed contacts on the lateral surface 15 of staving 2 ora terminalis 13 and first medial surface 16 of bung 1 outer wall 4; Convexity 12 closed contacts of second medial surface 17 of staving 2 top ora terminalis 13 and bung 1 top plan 5 inboards are so form sealing through closely cooperating of contact surface between bung 1 and the staving 2.Outer wall 4 inboard sealed muscles 18 can increase sealing property.The junction of tearing circle 3 and outer wall 4 has first thin-walled 9, and this first thin-walled 9 forms tears track.When needs are opened bung 1; To tear circle 3 through the unlatching mouth 10 of tearing circle 3 tears; Forming nick shaped at groove 11 places at the bottom margin that tears first clasp 8 of tearing circle 3 back bungs 1 breaks off; This moment bung 1 second clasp 14 of first clasp 8 and staving 2 ends between tightening force will be weakened, so can be free-hand firmly first clasp 8 of bung 1, second clasp 14 from staving 2 be pulled open, so just can bung 1 be opened very easily.Because the unlatching of this kind bung does not need by instrument, therefore can realize the easy open function of packing container.When the outer wall 4 of bung 1 is provided with second thin-walled 19; The groove 11 that second thin-walled 19 will break off first clasp 8 from the outside of outer wall 4 is sealed; Thereby it is inner to prevent that extraneous foreign material from getting into lid through groove 11; Because the zone that the wall ratio of second thin-walled 19 is closed on is thin, so the easy open function of bung 1 can not receive obvious weakening.

Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
