Description
Technical field
The invention belongs to pot type packing technique field, particularly a kind of Easy tearing lid and manufacture method thereof.
Background technology
The lid of current packing tin for foodstuff normally adopts iron sheet or aluminium skin to make, and encloses line of weakness at tank body one, by pulling the draw ring on lid to be torn along line of weakness by lid, thus can take out the article in tank interior.The lid of this structure, tears the larger power of needs when opening from indentation, and it is very inconvenient to open; And indentation place is sharper keen, the easy scratching fingers when taking out the article inside tank body.For this reason, at pot type packaging field, there is the Easy tearing lid made with aluminum foil sealing film, although this Easy tearing lid is torn than being easier to, easily there is the situation that pulling-on piece outwards tilts when but aluminum foil sealing film main body is fitted on lid, to cause pulling-on piece accidental in manufacturing line or follow-up intermediate links, or aluminum foil sealing film is surprisingly torn, thus cause the sealing effectiveness of Easy tearing lid to tank body poor, the problem such as easily cause the article in tank contaminated or unrestrained.
In order to overcome above-mentioned defect, the Easy tearing lid that a kind of aluminum foil sealing film is made has been there is in prior art, pulling-on piece arranges lug boss/recess, the corresponding setting recess/lug boss that fasten corresponding to the lug boss/recess on pulling-on piece in aluminum foil sealing film main body, by the riveted between lug boss and recess, realize pulling-on piece and turn down combination that is rear and aluminum foil sealing film main body.Although this mode can avoid pulling-on piece outwards to tilt and pulling-on piece outwards tilts the problems such as caused sealing effectiveness difference, but the structure of this lug boss/recess, just can must make by mould being pressed on aluminum foil sealing film main body and pulling-on piece, and mould is to the compacting of aluminum foil sealing film, easily cause aluminum foil sealing film to crack even to break, aluminum foil sealing film is caused damage, is unfavorable for the carrying out of subsequent technique; In addition, in the riveted and the process that is separated of lug boss and recess, also can damage aluminium foil because stress concentrates.
Summary of the invention
For this reason, technical matters to be solved by this invention is to overcome existing mode pulling-on piece and sealed membrane are riveted together, easily cause sealed membrane to crack even to break, to the hurtful defect of sealed membrane, thus the Easy tearing lid and manufacture method thereof that provide the combination of a kind of pulling-on piece and sealed membrane not easily to cause sealed membrane to crack even to break.
