Abstract

The anti-pollution top pop can for beverage features that its top cover and the partial side in touch with lip are enclosed by thermally shrinking film, which is tightly close to the top cover to prevent film from being damaged. Its production method includes pressing the partial film on side while thermally shrinking it to make it close to side wall of can, and thermally softening the film on top cover while pressing it to make it tightly close to the top cover.

Description

Pollution-proof top-pop-can, its prodn. method and processing unit

The present invention is a kind of beverage usefulness (comprising beer) pollution-proof top-pop-can and method and the processing unit (plant) of making this pop can.

The easy open can beverage of Xiao Shouing is contaminated easily outside a jar oral area position is directly exposed in the market.Though can clean before the beverage, be difficult to scrub, particularly there is the easy contamination thing of an annular channel a jar upper surface, brings the possibility of bacteria infection like this to drinking person.Chinese patent CN2122841u " jar mouth has the pop can of sanitation sticking " can not eliminate beverage and flow into the problem that the jar loam cake raceway groove that pollutes sucks the oral cavity again.

The method and the processing unit (plant) that the purpose of this invention is to provide a kind of pollution-proof top-pop-can and make this pop can, pollution-proof top-pop-can can prevent that jar mouth and ladle bowl on every side thereof from by outside contamination, can ensure that like this people are hygienic.

Above-mentioned purpose reaches like this: the easy-open lid that 1. seals pop can with plastic sheeting 2., pull-tab 3., jar loam cake part that 4. 6. pot sidewall contact with lip with greater than beverage the time to be preventing by outside contamination, 4. 1. film pressed close to a depression and a jar loam cake downwards above 4. at the jar loam cake.

2. one incisura is arranged 5. so that tear film in side film edge 1. at easy-open lid.

According to above-mentioned purpose be: have incisura plane heat-shrinkable film 5. 1. to be placed on the pop can upper surface circle or pyriform for the method for producing above-mentioned pollution-proof top-pop-can and inventing, pyriform film pyriform tip 1. is placed on 2. side of easy-open lid, push down film 1. in jar loam cake protrusion part 8., with film 1. by easy-open lid 2. the edge part of side push down at pot sidewall and 6. go up, 1. 1. film is shunk be close to the pop can pot sidewall 6. (to comprise and be close to jar loam cake) to film 4. in the 8. part beyond the top of protrusion in the part heating of protrusion beyond 8.; Push down film 1. protrusion 8. part or push down film 1. protrusion 8. beyond thermal contraction be close to pot sidewall part 6., downwards to film 1. in the 4. pressurization of the part above the central depression of jar loam cake, 1. 8. 8. and with interior part heating make film 1. press close to jar loam cake 4. to film simultaneously with interior part or at protrusion at protrusion.

With push down film 1. protrusion part 8. to the jar loam cake 4. the film above the central depression 1. portion of hot softening press down can with the film of protrusion beyond 8. 1. thermal contraction carry out simultaneously.

According to above-mentioned purpose and inventive method, for the processing unit (plant) of producing the pollution-proof top-pop-can invention is: external pressure tube (12) is pushed down circle or pyriform plane heat-shrinkable film 1. in pop can protrusion part 8., one group of pressing plate (11) on the external pressure tube (12) with film 1. easy-open lid 2. the edge part of side push down at pot sidewall and 6. go up, 1. remaining edge part is downward for prominent (14) the ironed film of inclination on the external pressure tube (12), with hot hair dryer or in heating cabinet, 1. 1. film is shunk to be close to pot sidewall 6. in the part heating of protrusion beyond 8. to film, external pressure tube (12) push down film 1. protrusion 8. part or one group at least two lonely plates lonely pressing plate of forming circle 10. push down film 1. beyond protrusion thermal contraction paste pot sidewall part 6., interior pressure pipe (13) downwards to film 1. in the 4. pressurization of the part above the central depression of jar loam cake, 1. 8. make the softening depression of film press close to jar loam cake 4. to film simultaneously with interior part heating at protrusion.External pressure tube (12) also can be made up of the arc-shaped piece more than.

Structure of the present invention, method are simple, easy to process, and cost is low.

Below by an embodiment the present invention is described.

Fig. 1 is membrane sealed pop can upper end scheme drawing;

Fig. 2 is Figure 1A-A section-drawing;

Fig. 3 is Fig. 4 B-B section-drawing;

Fig. 4 is envelope film processing unit (plant) birds-eye view.

Example one, see Fig. 3, Fig. 4, have incisura plane heat-shrinkable film 5. 1. to be placed on the pop can upper surface circle or pyriform, 1. the pyriform film is placed on the pyriform tip 2. side of easy-open lid.External pressure tube (12) to press down with pop can jar loam cake protrusion 8. cramping live film 1., one group of pressing plate (11) on the external pressure tube (12) with film 1. easy-open lid 2. the edge part of side push down at pot sidewall and 6. go up, the inclination on the external pressure tube (12) prominent (14) with film 1. remaining edge part press to down; Inherent pipe (13) gradually downwards to the jar loam cake 4. the film above the central depression 1. pressurize, with hot hair dryer or with heating cabinet 1. film is heated and the film of protrusion beyond 8. to be shunk be close to pot sidewall 6., 4. 8. protrusion press close to jar loam cake with interior film to lower recess, stop the heating allowing film 1. cooling shaping become Fig. 1 Fig. 2 finding.Packaging film 1. before can the jar loam cake 4. the concavity periphery place a soft suction pipe that is rolled into circle 9., see Fig. 2, beer can not put suction pipe.Because fold appears in film part 1. that external pressure tube (12) is pushed down below easily after thermal contraction, can set up one group and surround round lonely pressing plate 10., pushing down film at external pressure tube (12) 1. 1. is close to pot sidewall at the film of protrusion part heat shrink protrusion 8. beyond 8. and 6. decontrols external pressure tube (12) in the back, 10. push down with lonely pressing plate and to be close to pot sidewall film portion 6., use again interior pressure pipe (13) downwards gradually to the jar loam cake 4. the film above the central depression 1. pressurize and simultaneously 1. 8. and with interior film protrusion heated, make film press close to jar loam cake 4., can eliminate simultaneously in 1. fold of protrusion film 8..

Pressing plate (11) is pushed down film and is 1. allowed behind the edge part film 1. to purse up between each pressing plate (11), pressing plate (11) be prevent film 1. edge part 4. shrink to the jar loam cake.10. lonely pressing plate forms circle by two at least.External pressure tube (12) also can be formed circle by the lonely plate more than two or two.Pressing plate (11) can separate dress separately with external pressure tube (12).

An above-mentioned processing unit (plant) can be made on the machine, also more than one processing unit (plant) can be made on the machine, resemble rotary glass wine bottle bottleneck press seal press proof.

3. be pull-tab among Fig. 2,7. be tank at the bottom of.
