Abstract
The utility model provides a safe metal easy -open end of packing jar usefulness of explosion -proof gas. The utility model discloses a solve metal easy -open end that rivet rear side department on the present lid top surface was equipped with the groove section of easily breaking and have the groove section of easily breaking and can whole fracture and appear big breach in the twinkling of an eye, have gaseous related the liquid of pressure to explode from big breach to spout, bring to use and go up trouble defect in the packing jar. The technical scheme main points: including the lid with through the pull ring of closing -up on the lid top surface, processing has easy disconnection mouthful groove ring on the lid, and the pull ring is in an easy disconnection mouth groove intra -annular and inclines, rivet rear side department processing on the lid top surface has one section groove section of easily breaking that surpasss pull ring both sides limit, and the characteristic is the groove degree of depth that is close the middle zone of rivet in the groove section of easily breaking is darker, the groove degree of depth in the side region of middle zone both sides is more shallow. Follow middle zone's the groove degree of depth arrives the regional groove degree of depth of side can be hierarchical change mode or the mode of gradually changing.
Description
Technical field
The utility model relates to the seal cover cap on packing jar, specifically a kind of safe metal easy-open end of packing jar of anti-gas explosion.
Background technology
The metal easy-open end of existing packing jar at present, structure comprises lid and by the draw ring of closing-up on lid end face, lid is processed with easily broken opening groove ring, and draw ring is in inside easily broken opening groove ring.A kind of metal top pop cover of packing jar disclosed in No. 201520258267.0 of the applicant's earlier application, improvement feature is: draw ring is in easily broken opening groove ring and tab nose is in easily broken opening groove ring place, on rear side of rivet on described lid end face, place is processed with the easily broken groove section that a section exceeds draw ring dual-side, and the shape of described easily broken groove section is designed the shape of an imaging flying bird.The functional effect improved is: when the finger ring position of draw ring is lifted, described easily broken groove section can rupture in advance, then draw ring with the lid position outside easily broken groove section for fulcrum, as lever, force tab nose to fracturing easily broken opening groove ring, so just can reach that to open easily broken opening groove chain rate more laborsaving, avoid draw ring length must longer, thickness must thicker to avoid draw ring to be lifted time produce bending and lose leverage.But its shortcoming is: when the finger ring position of draw ring is lifted, described easily broken groove section may wholely rupture, the large breach occurred instantaneously, the pressed gas inconjunction with liquid that has in packing jar can be made to go out from the quick-fried spray of large breach, bring the trouble in use.
Summary of the invention
The metal easy-open end being provided with easily broken groove section in order to overcome place on rear side of the rivet on existing lid end face exists easily broken groove section can whole fracture and occur large breach instantaneously, the pressed gas inconjunction with liquid that has in packing jar goes out from the quick-fried spray of large breach, bring and use upper troublesome defect, the purpose of this utility model is to provide a kind of safe metal easy-open end of packing jar of anti-gas explosion of improvement, can overcome the defect of prior art.
The utility model solves the technical scheme that its technical matters adopts: a kind of safe metal easy-open end of packing jar of anti-gas explosion, comprise lid and by the draw ring of closing-up on lid end face, lid is processed with easily broken opening groove ring, draw ring is in inside easily broken opening groove ring, on rear side of rivet on described lid end face, place is processed with the easily broken groove section that a section exceeds draw ring dual-side, it is characterized in that: comparatively dark close to the groove degree of depth of the zone line of rivet in described easily broken groove section, the groove degree of depth of the side area of described zone line both sides is more shallow.
The groove degree of depth of technique scheme from the groove degree of depth of described zone line to described side area can be changed in stages mode or the mode that gradually changes.
Rivet described in technique scheme can be additional rivet or the rivet formed by the punching press of lid own.
The front end of draw ring described in technique scheme can be in described easily broken opening groove ring place.
Groove degree of depth difference in easily broken groove section described in technique scheme can be realized by the moulding of indentation diel.
Lid end face described in technique scheme can also be processed with applicable relief region.
Technique scheme what is called is darker and more shallow is that the zone line groove degree of depth and the side area groove degree of depth are compared therebetween, instead of represents a certain concrete numeral.
The beneficial effects of the utility model: because the groove degree of depth close to the zone line of rivet in described easily broken groove section is darker, the groove degree of depth of the side area of zone line both sides is more shallow, so when the finger ring position of draw ring starts to be lifted, the zone line meeting fracture in advance that the described groove degree of depth is darker, produce a little opening, the pressed gas that has of packing jar is allowed to release, then along with the finger ring position of draw ring continues to lift, described easily broken groove section is just split gradually, so just can avoid occurring that the pressed gas inconjunction with liquid moment that has in packing jar goes out from the quick-fried spray of large breach, to using the problem made troubles.
Below in conjunction with drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
With reference to Fig. 1 ~ Fig. 3, the safe metal easy-open end of the packing jar of this anti-gas explosion, comprise lid 1 and by the draw ring 3 of rivet 2 riveted on lid 1 end face, lid 1 is processed with easily broken opening groove ring 4, draw ring 3 is in inside easily broken opening groove ring 4, on rear side of rivet 2 on described lid 1 end face, place is processed with the easily broken groove section 5 that a section exceeds draw ring 3 dual-side, it is characterized in that: comparatively dark close to the groove degree of depth of the zone line 6 of rivet 2 in described easily broken groove section 5, the groove degree of depth of the side area 7,8 of described zone line 6 both sides is more shallow.
In addition, the described groove degree of depth from the groove degree of depth of zone line 6 to described side area 7,8 is changed in stages mode.Described rivet 2 is additional rivet.The front end 9 of described draw ring 3 is located at described easily broken opening groove ring 4 place.Lid 1 end face is also processed with applicable relief region 10,11 etc.
With reference to Fig. 4, the groove degree of depth from the groove degree of depth of zone line 12 to described side area 13,14 is the mode of gradually changing.
