Description

The pop can of overall plastic band suction pipe

The present invention relates to a kind of pop can, more particularly, relate to a kind of pop can of overall plastic band suction pipe.

In order to drink various beverages easily, the applicant's Chinese utility model patent ZL98225192.0 discloses a kind of " pop can of band suction pipe ".This pop can is made up of cover, tank body, draw ring and suction pipe.Cover and tank body can be fixed together by conventional welding method, suction pipe then by be installed in draw remove part go up on the round ring boss pitman be suspended under the cover.This pop can the pull-up draw ring will draw remove part and start in, also suction pipe is taken out of outside the cover, thereby the person of being easy to use avoids drinkable liquid to be subjected to outside contamination to keep beverages health to the drinking of the beverage in the jar.Though the pop can of above-mentioned band suction pipe has solved it originally not with a series of inconvenience and hygienic issues that suction pipe produced, but its structure design only is suitable for the pop can made by aluminum alloy, so that cost is higher.

The object of the present invention is to provide a kind of cover of pop can of the overall plastic band suction pipe of making by whole plastic material.

For achieving the above object, the pop can of overall plastic band suction pipe of the present invention comprises loam cake, tank body, the draw ring of fixed orifice is contained at its rear portion, a suction pipe and an end have the suction pipe holding element that the suspension suction pipe is used, be covered with on described and can draw the buckling groove that is positioned at the lid edge and matches except that partial sum with tank body top, fix a draw ring and a suction pipe holding element thereon on the lower surface respectively, wherein, one of inside and outside ring wall that described buckling groove is relative is provided with annular relief, the inside and outside wall on the top of described tank body be provided with buckling groove inside and outside the annular groove section of annular relief complementation of one of ring wall, in addition, tank body is provided with a boss portion on the upper surface, after the bottom land seam of boss portion and buckling groove, the then relative engagement of annular relief with annular groove section.

The pop can of overall plastic band suction pipe as previously discussed, wherein, the middle part of described loam cake has prominent recessed cylindrical wall on, the other end that described suction pipe holding element is relative with an end that hangs suction pipe has the vertical short tube portion of a relative holding element longitudinal axis, the fixed orifice of described draw ring can be enclosed within on the face of dashing forward on the cylindrical wall, and the short tube portion of described suction pipe holding element can insert in the recessed depression of cylindrical wall, and by welding is fixed on the loam cake top and bottom draw ring and suction pipe holding element to cylindrical wall pressure.

The pop can of overall plastic band suction pipe as previously discussed, wherein, the lower surface of described loam cake removes the ring stiffener that is provided with a downward protrusion between the part at buckling groove and Ke La.

Therefore, the present invention is by being provided with the pop can that the failure-free connection structure has solved overall plastic band suction pipe made of plastic between cover and the tank body, the characteristics that can keep the pop can of existing band suction pipe simultaneously, for example the suction pipe upper end can be drawn out tank body with opening after opening, the convenient jar interior beverage of sucking, meet the health demand that people drink pop can, in addition, the present invention only need dispose the welding gear that adapts with plastically welding just can not producing on the pop can high-speed flow line manufacturing line with suction pipe or band suction pipe at aluminum, and be suitable for making the pop can of different volumes size, can big cost-cutting and have rational in infrastructure, use health, convenient, reliable and can recycling and help advantage such as environmental protection.

Below will also do further to state in detail to purpose of the present invention and effect in conjunction with the accompanying drawings by embodiment:

The detailed description of the embodiment of the invention

See also shown in Fig. 1～Fig. 6 a, 6b, the pop can of the overall plastic band suction pipe among the present invention comprises a loam cake 1, a tank body 2, a draw ring 3, a suction pipe holding element 4 and a suction pipe 5.Loam cake 1 is provided with in the one side and can draws except that part 11, in the middle, promptly being positioned at the inboard that can draw except that part 11 is provided with a protrusion 12 and is being positioned at its lid along being provided with an annular buckling groove 13, wherein, this protrusion 12 has prominent recessed square or cylindrical wall (not drawing among the figure) on, and one of inside and outside relatively ring wall of this buckling groove 13 is provided with an annular relief 14.

Tank body 2 is provided with a boss portion 21 on upper shed end face 21, be provided with the annular groove 22 with annular relief 14 complementations of one of buckling groove 13 inside and outside ring walls on one of the inside and outside wall on top.Like this, when loam cake 1 is installed on the tank body 2 before welding, the boss portion 21 of tank body 2 contacts or is close with buckling groove 13 bottom lands of loam cake 1, and the annular groove 22 of tank body 2 is meshed with the annular relief 14 of loam cake 1, to guarantee the leak tightness after loam cake 1 is soldered on the tank body 2.
