Description
Technical field
The utility model relates to the plastic barrel that a kind of lid is prone to unlatching, belongs to the plastic packaging containers field.
Background technology
At present, the opening ways of the sealed plastic packing barrel 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 easy to use, easy plastic barrel of opening of lid is provided.
The technical scheme that realizes the utility model purpose is: a kind of lid is prone to the plastic barrel of unlatching; It comprises bung and staving, and bung comprises outer wall, top plan, inwall, big plane, center and be positioned at the circle of tearing of bung bottom, tears to have on the circle and opens mouthful; Be provided with first clasp in the inboard of outer wall; Tear to have between circle and the outer wall and form a thin-wall groove, this groove is for being the wavy shaped configuration of center and alternatively up and down with first clasp, and 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.
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.When needs are opened bung, will tear circle through the unlatching mouth of tearing circle and tear.The thin-walled of the formed same shape of corrugated groove constitutes tears track, and groove is broken into plurality of sections with first clasp, because the corrugated track part of tearing is above first clasp; A part is below first clasp in addition; So first clasp tearing below the track will be torn along with tearing circle simultaneously, and first clasp of tearing track above still is retained on the bung, owing to part first clasp of bung is torn; Tightening force between bung and the staving will receive tangible weakening; So just, can bung be opened very easily,, therefore realize the easy open function of packing barrel because the unlatching of this kind bung does not need by instrument.Simultaneously; Because the bung after opening still has part first clasp to be retained on the bung; Therefore will tear the bung of tearing circle and cover once more when bung, first clasp on the bung under residual and second clasp at staving top can fasten again each other, so can realize the repeated usage function of lid again.

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 ~ 6, a kind of lid is prone to the plastic barrel of unlatching, and it comprises bung 1 and staving 2; Bung 1 comprise outer wall 4, top plan 5, inwall 6, big plane 7, center and be positioned at bung 1 bottom tear the circle 3; Tear circle and have on 3 and open mouthfuls 10, be provided with first clasp 8, tear and have the groove 9 that forms a thin-walled 9-1 between circle 3 and the outer wall 4 in the inboard of outer wall 4; This groove 9 is to be the wavy shaped configuration of center and alternatively up and down with first clasp 8; The top of staving 2 is provided with ora terminalis 12, also is provided with second clasp 13 that cooperates with first clasp 8 on the staving 2, and this second clasp 13 is positioned at the below of ora terminalis 12; Bung 1 inboard is provided with the convexity 11 that cooperates with ora terminalis 12, and this convexity 11 is between outer wall 4 and inwall 6.
Like Fig. 5, shown in 6, described outer wall 4 inboards are provided with sealed muscle 14, and sealing muscle 14 is positioned at the top of first clasp 8.The cross-sectional plane of described sealed muscle 14 is a triangle.
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 13 of staving 2 ends fasten each other at this moment.When second clasp 13 of first clasp 8 of bung 1 and staving 2 ends fastens each other; Sealed muscle 14 closed contacts on the lateral surface 15 of staving 2 ora terminalis 12 and first medial surface 16 of bung 1 outer wall 4; Convexity 11 closed contacts of second medial surface 17 of staving 2 top ora terminalis 12 and bung 1 top plan 5 inboards are so form sealing through closely cooperating of contact surface between bung 1 and the staving 2.Sealed muscle 14 on first inboard 16 of outer wall 4 can increase sealing property.When needs are opened bung 1, will tear circle 3 through the unlatching mouth 10 of tearing circle 3 and tear.The thin-walled 9-1 formation of corrugated groove 9 formed same shapes is torn track; Groove 9 is broken into plurality of sections with first clasp 8; Because the corrugated track part of tearing is above first clasp 8, a part is below first clasp 8, so will be torn simultaneously along with tearing circle 3 at first clasp of tearing below the track 8 in addition; And first clasp of tearing above the track 8 still is retained on the bung 1; Because part first clasp 8 of bung 1 is torn, the tightening force between bung 1 and the staving 2 will receive tangible weakening, so just can bung 1 be opened very easily; Because the unlatching of this kind bung 1 does not need by instrument, therefore realize the easy open function of packing barrel.Simultaneously; Because the bung 1 after opening still has part first clasp 8 to be retained on the bung 1; Therefore will tear the bung 1 of tearing circle 3 covers once more when bung; First clasp 8 on the bung 1 under residual and second clasp 13 at staving 2 tops can fasten again each other, so can realize the repeated usage function of bung 1 again.
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.
