Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail。
Provided by Fig. 1 to Fig. 4, the technical scheme is that, including bottle 1 and buckle closure 2, on bottle 1 open circles perisporium, pressing has a pushing out ring 3, described pushing out ring 3 inner edge surface is provided with to the projecting inward annular brace platform 4 of bottle 1 opening, described annular brace platform 4 is connected to metal cover 5 through circular easy-to-draw trace, described buckle closure inner headed face is provided with female thread 11, the mid portion of described pushing out ring 3 outer edge surface is protruded with flange 6 to bottle opening and constitutes the structure that can block dress female thread 11, described buckle closure 2 is made up of PET material, the bottle of described pushing out ring 3 lower end is provided with the external screw thread 12 matched with female thread 11, described metal cover 5 upper surface is connected to draw ring 8 through rivet 7, what draw ring 8 was positioned at rivet 7 front end is partially disposed on circular easy-to-draw trace and for most advanced and sophisticated 801, draw ring 8 is positioned at the metal cover 5 of lower end, rivet 7 rear portion and is provided with groove 9 of stepping down, the metal cover 5 of draw ring 8 both sides be provided with extend back reinforcement 10。
The bottle 1 of described external screw thread 12 lower end be provided with protrude outward around the bottle step of 1 one weeks 16。Added with step 16, it is possible to help bottle 1 molding。The length that the outwardly length of step is outwardly less than external screw thread。
Described buckle closure 2 and female thread 11 are made up of PET material in integrative-structure。When buckle closure 2 be enclosed within pushing out ring 3 is pressed downward against time, female thread 11 and flange 6 are extruded mutually steps down, make buckle closure 2 by flange 6, female thread 11 by after flange 6 by screens flange 6 times, buckle closure 2 can be covered tightly on bottleneck, ensure that the safety of the internal food of bottle 1 is not easily trickled down, when needs take off buckle closure 2, only need to be pulled upwardly buckle closure 2, again such that female thread 11 and flange 6 are stepped down mutually, buckle closure 2 is taken away, after female thread 11 is stuck on flange 6, can continue to be screwed in downwards on external screw thread 12, ensure that the tightness of buckle closure, added with screw thread can so that after internal metal flip is opened its sealing effective。After being combined with metal cover by screw thread before ensure that Kaifeng and breaking a seal, internal food all can well preserve, and the cross section of flange 6 is arc or triangle。
Described bottle 1 top is provided with the shoulder 13 for spacing buckle closure 2 lower end。When buckle closure 2 is buckled in downwards on flange 6, the now top of buckle closure 2 and pushing out ring 3 top contact, and buckle closure 2 bottom contacts with shoulder 13, plays the good locations stability to buckle closure 2。
The metal cover 5 at described rivet 7 rear portion is provided with the easy tear mark 14 of the arc centered by rivet 7。When in use, when draw ring 8 is from rear portion pull-up, its most advanced and sophisticated 801 downward thorn easy-to-draw trace of opened round, rivet 7 makes easy tear mark 14 rupture, take up the part metals capping of easy tear mark 14 front end, then draw metal cover 5 again so that the easy-to-draw trace fracture of circle of whole metal cover 5, finally make metal cover 5 depart from bottle 1。The pull-up of draw ring 8 is easily facilitated added with easy tear mark 14。
The pulling-on piece that described draw ring 8 is connected by annulus and the annulus front end one at rear portion is constituted, and rivet interlacement is on pulling-on piece, and most advanced and sophisticated 801 are arranged on pulling-on piece front end。
Be interval with major arc shape fin 15 on described metal cover 5 with its edge, the opening of described major arc shape fin 15 is towards rivet 7, and the opening two ends of major arc shape fin 15 do not contact draw ring 8。Major arc shape fin 15 strengthens the intensity of metal cover 5 so that it will not be circled when draw ring 8 pull-up, but probably horizontal is started so that be easier to be pulled up when metal cover 5 sealing strength is certain。The straight line parallel at the center that pin is arrived at reinforcement and tip is arranged, and its effect is easily, when starting metal cover, it is played booster action so that it is not easily roll。
Described most advanced and sophisticated 801 in the lower shape extending bending forward, advantageously in puncturing circular easy-to-draw trace。
When the present invention uses, owing to the metal cover 5 at draw ring 8 rear portion is provided with groove 9 of stepping down, finger is made to be easy to extend into below the annulus at draw ring 8 rear portion, to such an extent as to convenient pull-up annulus, without causing puzzlement to pull-up annulus, use the buckle closure of PET material, the material making buckle closure is harder, it is unlikely to deform, rounding property is higher, and PET has certain transparency, after metal cover is torn, can be passed through it and observe the food within bottle, it has good mechanical property, impact strength is good, creep resistance, fatigue durability, rub resistance and good stability of the dimension。Added with annular brace platform so that metal cover board has enough bit spaces that allows when starting so that there is certain interval itself and a pushing out ring medial wall。
Buckle closure hardness of the present invention is high, transparency is good, it is unlikely to deform, rounding property is good, coordinates buckle closure not easily to drop with the pushing out ring on bottle and external screw thread, it is ensured that the safety of food and not easily trickling down, metal cover arranges reinforcement and excellent arcuate rib, bending resistance is strong, it is easy to tear, and the easy tear mark of arc is arranged and the setting of groove of stepping down makes draw ring pull-up convenient。
