Description

a fluid packaging

technical field

The invention relates to the technical field of fluid packaging, in particular to a fluid packaging.

Background technique

The existing packaging technology for fluid packaging bags is widely used in the fields of beer and other food, but there are still many problems:

1. It is difficult to open. When people are traveling or leisure and want to use the medicine in the packaging bag or eat the food in the packaging bag, it will be difficult to open this kind of packaging bag because they do not have an opening tool with them. embarrassing situation;

2. It is unhygienic. When the packaging bag is broken, the objects in the packaging bag are easy to contact the printing materials on the packaging bag, causing pollution to the food or medicine in the packaging bag;

Three, unsafe, when opening, easily occur liquid splash, dirty people's clothing, also caused the unnecessary waste of object in the packaging bag.

4. For the liquid food that is taken many times, after taking the food every time, the air enters the package, and the oxygen in the air enters the package to oxidize the food. The manufacturer adds antioxidants to the food, and the bacteria enter the package, causing food infection. After bacteria, the shelf life is greatly shortened. In order to prolong the shelf life, manufacturers add preservative sodium benzoate to food. Can't satisfy consumer's increasingly to edible food safety, hygienic requirement.

Five, the cost is higher, which hinders the development of fluid packaging bags and the promotion and use of large areas.

Contents of the invention

The purpose of the present invention is to provide a fluid packaging that can take fluid food for many times without causing bacteria to grow and deteriorate in the food.

The technical solution adopted by the present invention to solve the problems of the prior art is: a fluid packaging, including a packaging bag and a flange, the flange and the packaging bag are heat-sealed as a whole, and an overflow valve is provided in the flange. An upper cover is also provided on the blue; the overflow valve includes an elastic body and an elastic plug matching the size of the overflow valve port, the first bracket and the second bracket in the elastic plug are connected by an elastic body, and the second bracket is provided with a There are small holes.

Fluid food is injected into the packaging bag through a small hole, and the elastic body is in a pre-stretched state to ensure that the fluid will not flow out automatically even when it is upside down in the packaging bag. The fluid will only flow out when the packaging bag is additionally pressurized; among them, adjust The length and thickness of the elastic body can adjust the size of the pre-stretching force.

The rubber band that the preferred food-grade silica gel of described elastomer is made;

There is a downwardly recessed groove at the upper end of the flange;

A pressing plate is placed on the groove;

The center of the pressing plate is hollowed out so as to facilitate the injection and removal of fluid food;

The upper end of the pressing plate is provided with a pull ring, which is a disposable pull ring;

The shape of the rubber plug is conical or ellipsoidal;

The flange and the upper cover are connected by threads.

After the above structure is adopted in the present invention, the flange and the packaging bag are heat-sealed as one, the overflow valve in the flange ensures that the fluid will flow out only when the packaging bag is additionally pressurized, and the pull ring makes the sealing of the packaging bag Guaranteed, the flange and the upper cover can be used repeatedly, so that the fluid food can be taken for many times without causing the food to breed bacteria and deteriorate. The invention also has the advantages of low production cost, simple structure, convenient and safe operation, etc., and has a strong promotion sex.

detailed description

A specific embodiment of the present invention will be further described in detail below in conjunction with FIG. 1 .

The fluid packaging of the present invention includes a packaging bag 1 and a flange 2, the flange and the packaging bag are heat-sealed as a whole, an overflow valve 3 is arranged inside the flange 2, and an upper cover 4 is also arranged on the flange 2; wherein the overflow valve 3. It includes an elastic body 31 and an elastic plug 32 that matches the size of the overflow valve port. The first bracket 33 and the second bracket 34 in the elastic plug 32 are connected through the elastic body 31. The second bracket 34 is provided with a small hole 35 The upper end of the flange 2 has a downwardly recessed groove 5, and a pressing plate 6 is placed on the groove 5. The center of the pressing plate 6 is hollowed out, and the upper end of the pressing plate 6 is provided with a pull ring 7. The shape of the rubber plug 32 can be tapered or Ellipsoid, the flange 2 and the upper cover 4 are connected by threads. The elastic body 31 is preferably a rubber band made of food-grade silica gel.

The working principle of the present invention: put quantitative fluid food in the packaging bag, pressurize the air in the bag through the small hole on the second bracket of the one-way overflow valve, seal the overflow valve with a pull ring and put the cover on cover, which can prevent oxygen from reacting with the food, and inactivate the bacteria in the bag; the user opens the upper cover to tear off the pull ring during use, and squeezes the food out of the overflow valve from the bag, because the bag is soft After the liquid food is taken out of the bag, it does not need air to fill the bag, and no oxygen and bacteria enter the bag. After taking it, cover the valve port with an outer cover to prevent the valve port from being exposed to the air for a long time; squeeze When the elastic body in the overflow valve becomes longer, there is a gap in the valve port of the overflow valve, and the fluid food flows out of the valve port. When the packaging bag loses pressure, the elastic body shrinks, and the valve port of the overflow valve is closed to prevent the air from flowing backward into the packaging bag. ; Thereby, it can ensure that the fluid food is taken for many times without causing the food to breed bacteria and deteriorate, and the structure is simple, and the operation is convenient and safe.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Any skilled person who is familiar with the profession, without departing from the scope of the technical solution of the present invention, can use the technology disclosed above. The content makes some changes or modifications to equivalent embodiments of equivalent changes, but all the simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention are still the same It belongs to the scope of the technical solutions of the present invention.
