Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

Fig. 2 to Fig. 4 schematically shows a kind of bellows pocket of embodiment according to the present utility model.As shown, The device includes a bag body 1, and the two sides of bag body 1 are equipped with the organ side being folded inward, and the top of bag body has opening, opening It is sealed by hot pressing.

Wherein, lower section is set there are two tearable mouth 2 at the sealing of bag body 1.

Two tearable mouths 2 are respectively arranged on the two sides in the transverse direction of bag body 1.

Two tearable mouths are used to position opening A when opening packaging, and when tearing bag body 1, the A that is open is by the easy of side Tearing notch 2 extends laterally to the tearable mouth 2 of the other side.

Bag body 1 is generally made by film stretching in the transverse direction.Thus it easily facilitates when opening and laterally tears.

In a further embodiment, bag body 1 can also be made by the film that multilayer material is combined, in multilayer material extremely It less include one layer of film stretching in the transverse direction.

Preferably, film stretching in the transverse direction is cross directional stretch polyethylene film or cross directional stretch polypropylene film.

In the present embodiment, bag body 1 is additionally provided with a sealing fixture 3.Sealing fixture 3 is set under the opening of bag body 1 Side.

Sealing fixture 3 is used to be fixed by the bag body 1 after Open Side Down convolution.Bag body 1 after opening as a result, is more Add convenient for sealing.

In the present embodiment, sealing fixture 3 is a bent iron plate.

Iron plate is laterally arranged along bag body 1,

It is fixed in the middle part of iron plate with 1 surface of bag body, 1 top of bag body, which can be wound on iron plate, carries out convolution.Bag body 1 can as a result, It is more convenient to carry out convolution by axis of iron plate.

1 two sides of bag body are stretched out at the both ends of iron plate respectively, and bag body 1 passes through 1 convolution of bag body by iron plate after Open Side Down convolution Both ends are bent to identical direction respectively behind part, and the other parts of the part of 1 convolution of bag body and bag body 1 are fixed.It opens as a result, Bag body 1 after opening easily facilitates sealing.

In the present embodiment, liner 4 is additionally provided with inside bag body 1.

The hard box body 41 and the product packing box 42 inside hard box body 41 that liner 4 includes a upper opening.

Hard box body 41 and product packing box 42 are the shape of cuboid.

Equipped with one or more product packing box 42 of phase side by side, a product packing box 42 or more in hard box body 41 A product packing box 42 is tightly matched with the space inside hard box body 41.

Shape after the shape of hard box body 41 is unfolded with bag body lower part matches, and product packing box is set in rigid packet body Portion, and can be extracted by the opening on 41 top of hard box body.

During hard box body 41 can not only make bag body 1 fall and beat, it is not susceptible to damage, and pass through elasticity Effect, product packing box 42 is buffered and is supported, to have good protective effect to product packing box 42.

In the present embodiment, bag body 1 is provided with rounded corner.So that user will not be because of four angles excessively cutting edge of a knife or a sword of bag body 1 Benefit and damage.

Using the bellows pocket of above technical scheme, opening can be laterally extended between two tearable mouths, and bag body is using After can be closed again.Therefore the bellows pocket can be used as outer packing reuse, has not only saved resource, has reduced wave Take, and use is also more convenient.

Above-described is only some embodiments of the utility model.For those of ordinary skill in the art, Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical Novel protection scope.
