Description
Technical field
The utility model is relevant with the easy open can structure, more detailed it, refer to a kind of easy open can of plastic cement material especially.
Background technology
Known easy open can covers in conjunction with aluminium can with the aluminium can body, and tank body and cover are made with the metal paattern punching press respectively, and forms a draw ring cut channel on cover when punching press, an end Colaesce one draw ring in this draw ring cut channel scope.After the tank body filling liquid content, cover is incorporated into the tank body top with capsuling machine.This draw ring of user's drawing will make cover form an opening along this draw ring cut channel.
This kind easy open can uses for a long time, has following problem at manufacture view:
The depth control of above-mentioned draw ring cut channel punching press needs very accurate, because the dark excessively relative interior structure of ring plate Colaesce on cover of its scope of draw ring cut channel of the degree of depth tails off, the stability of ring plate reduces, and because of the gaseous tension in the jar ring plate is popped probably.And the structure of ring plate Colaesce on cover in relative its scope of the too shallow draw ring cut channel of the degree of depth is more, will make ring plate be not easy to be drawn back by draw ring.Hence one can see that, and the precision control of this draw ring cut channel really is the difficult part of implementing, and increase the quantity of easy open can faulty materials.
In addition, last karat gold belongs to mould after long-term use, is subjected to the pressure effect of punching press to produce distortion easily, and the service life of mould is short, and buys more the cost height of new die, the relative profit that influences manufacturer.
Novel content
Problems such as main purpose of the present utility model is, a kind of polymer easy open can structure is provided, and precision control short for the die life that solves the metal easy open can, the draw ring cut channel is difficult propose an effective and concrete solution.This solution is made the easy open can structure with plastic cement material substituted metal material.
Technical solutions of the utility model:
A kind of polymer easy open can is characterized in that, includes:
One polymer tank body, its top jar mouth place driving fit has a polymer cover, has a perforate on this polymer cover, and this tapping has a sealing lid, and sealing lid and perforate ora terminalis joint have a safe seam;
One polymer draw ring, one end are the draw ring portion of a ring-type, and the other end has the draw ring lid of a shape corresponding to this perforate, and this draw ring lid driving fit is coated on this tapping, and this draw ring lid cements in the sealing lid.
The utility model progress effect:
One of the purpose that the utility model is reached and effect are to constitute the easy open can structure with polymer tank body, polymer cover and polymer draw ring, break through tradition with the restriction of aluminum metal as the easy open can main material.
Two of purpose that the utility model is reached and effect is that this case does not adopt metallic material to make easy open can, promptly do not have the precision of the easy open can of metal described in prior art draw ring cut channel and controls problems such as difficult.And the forming mould of the utility model cover and tank body is without the impact of punching press equipressure, so can expect for long system than the forming mould of metal service life.Therefore this case can be low than the metal easy open can aspect material cost, manufacturing cost.
Three of purpose that the utility model is reached and effect is that sealing lid of the present utility model and polymer cover are formed in one, can guarantee that this perforate is in the polymer draw ring and opens before, have hundred-percent airtight effect; In addition, the draw ring lid driving fit of the utility model polymer draw ring is coated on this tapping, also has airtight effect, the seepage control technique of twice, can guarantee content or jar in the anxiety of gas ne-leakage.
Four of purpose that the utility model is reached and effect is that airtight effect is good, and the utility model cover and tank body binding end part are handled combine through super sonic or high frequency waves and fixed, and make cover and tank body not have the anxiety of separation, more can promote airtight effect.
Five of purpose that the utility model is reached and effect, system has cooresponding comfort feature on using, the utility model can make the sealing lid tear up from this tapping along this safe seam in the mode of drawing back the polymer draw ring, can drink polymer tank interior liquid from this tapping for the user, occupation mode is simple and convenient, in addition, the utility model is by separate slot setting between this peritreme top, can guarantee to seal between lid and draw ring lid when handling with super sonic or high frequency waves, the sealing lid can not combine with this peritreme top, thereby it is more smooth to make this polymer draw ring open.

The specific embodiment
Shown in Fig. 1～Fig. 4 drawing, a kind of polymer easy open can of the utility model comprises:
One polymer tank body 10, the outer diametric plane of its top jar mouth are integrally formed with the jar edge 11 that a ring-type is protruded;
One polymer cover 20, the lid edge 22 that it has a lid body 21 and is shaped in its periphery; This lid edge 22 is established a groove 221 and is supplied the jar mouthful wall of this tank body to embed wherein, and the cell wall of this groove 221 is provided with one can cater to wherein lid joint portion 222 fully for this jar edge, wherein, this jar edge 11 is combined fixing with 222 of lid joint portions with super sonic or high frequency waves; On this lid body 21 and be provided with a perforate 23, these perforate 23 peripheries have a peritreme that raises up 231, be provided with a sealing lid 24 in this place, perforate 23 open ends, and sealing lid 24 is provided with a safe seam 241 with peritreme 231 joints, makes sealing lid 24 airtight involutions in these perforate 23 places; Wherein, the top end of this peritreme 231 is concaved with an interval trough 232;
