Description

The with protecting cover pop can of draw ring

Technical field

The with protecting cover pop can of draw ring belongs to the flexible package punch field, relates to a kind of beverage cans.

Background technology

Network once spread a women has drunk can drink, is sent to hospital, has left this world.Autopsy finds that the beverage that she drinks is subjected to the pollution of mouse urine, has infected leptospira virus.So, how is the pop can sanitary condition in the reality?

I have visited supermarkets such as Ou Shang, Carrefour, Jing Ke-long, find in the market tinned drink, beer, and two kinds of opening ways are arranged, and a kind of is that draw ring outwards opens, and another kind is that draw ring is inwardly opened (being that opening ways is by advancing in the jar with draw ring).The key distinction of two kinds of pop cans is, draw back draw ring after, the former draw ring separates with tank body, and the latter is connected as a single entity.

In a tame supermarket, I see, there are special row's shelf to put the beverage of various pop can packings in the beverage district, Coca-Cola under the Coca-Cola, zero degree cola, diet coke, Sprite, Finda etc., Pepsi Cola under the Pepsi Co. Ltd., Seven Up adopt all turns over the formula draw ring in being, in addition, drinks such as WANGLAOJI LIANGCHA, prosperous young milk, Yanjing Brewery turn over the formula draw ring in also all using.I have smeared at various pop can bottlenecks gently with hand, just have been infected with the very thin dust of one deck on the finger.

According to data, at present in the beverage industry of pop can packing, in turn over the formula draw ring and the external pulling type draw ring probably respectively accounts for half, but, in turn over the formula draw ring increasing trend arranged.Reason is: if you examine, turn over the formula draw ring in fact and the external pulling type draw ring has a great difference, except the face shaping difference, both draw back the back bottleneck and also are not quite similar, in to turn over the bottleneck area of formula draw ring bigger, allow the people feel to drink happily without hindrance, also more can promotion, thus in turn over the formula draw ring and also welcome by enterprise; Turn over the generation that the formula draw ring has prevented draw ring rubbish simultaneously.

Be the situation of selling well season of various beverages, beer summer, yet, in the recent period, relevant for turning over formula draw ring possibility breed bacteria in beverage, the beer packing pop can maybe with the message of abolishing, cause customer's concern.Investigation finds, except the interior formula pop can that turns over exists the hygienic issues, the eversion type pop can, etc. the packing health of Other Drinks cause anxiety equally.For a lot of people, in the time of thirsty, draw back one bottle of easy open can beverage, face upward head and toss off the cup, be the most usual way.But, this drinking way and unhygienic.Because pop can jar mouth is exposed to the external world for a long time, so it is very big to be infected with the possibility of breed bacteria viral source.And, in not merely appearing at, this situation turns on the pop can of formula draw ring, and the pop can of external pulling type is like this equally.

Summary of the invention

In order to overcome the above-mentioned defective of present pop can, the invention provides the pop can that a kind of draw ring can cover opening, can prevent that the pop can opening part from being polluted.

The present invention has taked following technical scheme:

The with protecting cover pop can of draw ring, be matrix with the interior formula opening pop can that turns over, comprise the pre-opening at pop can top and turn over the pressure type draw ring, the described pressure type draw ring that turns over is ring bodies, one end of this ring bodies is tried to gain the center that is punched in the pop can top, and this is held and is that sharp-pointed shape, its other end are slick and sly arc; And be provided with the plates that cover the pre-opening part of pop can in the middle of the described ring bodies, these plates and described sharp-pointed shape one end that turns over the pressure type draw ring are connected as a single entity, and the area of described plates is greater than the area of described pre-opening.

Not contaminated in order to guarantee the pop can opening more perfectly, at described pop can top covered protection overlay film.

When opening pop can, earlier draw ring partly being started, serves as that axle will turn over pressure type draw ring Rotate 180 ° with the Mu Ding of fixed pull ring then, the pre-opening that exposes pop can like this starts draw ring more fully, utilizes lever principle, the mounting of pre-opening part turned over be depressed in the jar, open pop can.And, the plates rotation can also be got back to opening part, shelter from opening again.

The invention has the advantages that: the present invention is on interior basis of turning over the formula pop can, turning over plates of pressure type draw ring design as protective cover, plates and the design of draw ring one utilize the middle material of draw ring as plates, plates cover on the pre-opening of pop can, play the protective cover effect.Like this, just guaranteed pop can before use, its opening part is in occlusion state always, prevents that the pre-opening part of pop can is subjected to outside contamination.And, if beverage is not once finished off, protective cover can also be rotated back to opening part, can temporaryly block dirt, ensure that beverage is not contaminated.Protective cover forms in the manufacture craft of original draw ring, makes with protecting cover draw ring cost of manufacture lower and manufacture craft is simple.Can also draw advertisement at this protective cover in addition, obtain more economic benefits; If adopted this protected mode, also can show the quality elegance that enterprise is responsible for customer's beverage quality to a certain extent on safe and sanitary.
