Description

Damping bag with square bottom

Technical field

The utility model is related to sack, particularly to bag with square bottom, Vertical-bag.

Background technology

Its bottom of bag with square bottom is square, and bag with square bottom typically has 5 faces, front of and behind（I.e. antetheca and rear wall）, two sides Face, and bottom surface, bag with square bottom can be stood, alternatively referred to as Vertical-bag.The unique construction of bag with square bottom determines the three-dimensional goods of packaging Or square products are more convenient.

Utility model content

In view of technical problem present in background technology, the technical problem that the utility model is solved aims to provide a kind of new The damping bag with square bottom with shock-absorbing function of type.

For solving above-mentioned technical problem, the utility model adopts the following technical scheme that：Damping bag with square bottom, its feature exists In：The bag material of this damping bag with square bottom adopts the composite of bubble chamber film, and bag includes antetheca, rear wall and bag bottom, antetheca The left and right sides is connected with the left and right sides correspondence of rear wall, and the bottom of antetheca and the bottom of rear wall are attached by bag bottom, bag Bottom is to insert bottom structure, and four base angles that bag bottom is formed with antetheca and rear wall are obtuse angle.

Composite is that PET, PE, paper or aluminizer and bubble chamber film are composited, on bag bubble chamber film in inner side, PET, PE, paper or aluminizer are in outside.

Also it is combined PE layer in the inner side of bubble chamber film.

The left and right sides of antetheca is connected by corresponding sealing with the left and right sides of rear wall.

Antetheca and rear wall are sealed with the junction at bag bottom.

Bag forms antetheca and rear wall by after whole composite material foldable, in the junction of antetheca and rear wall to interpolation bottom shape Become bag bottom.

In the bottom of antetheca and rear wall, the sealing corresponding with the left and right sides at bag bottom of the left and right sides of antetheca, the left and right of rear wall Both sides sealing corresponding with the left and right sides at bag bottom.

Sealing is 0.5 ~ 1.5 centimetre using broadside sealing, the envelope line width of broadside sealing.

The obtuse angle that bag bottom is formed with antetheca and rear wall makes antetheca and the bottom of rear wall have inverted trapezoidal structure.

The beneficial effects of the utility model are, there is provided a kind of brand-new bag with square bottom with damping effect, protect well Shield is placed on the article in bag, and the base angle of bag is obtuse angle, and will not be squeezed formation wedge angle, and bag can steadily be stood Vertical, do not have thing and fall in wedge angle.Therefore, the utility model compared with prior art has substantive distinguishing features and progress.

Brief description

Relevant details and the operation principle of embodiment of the present utility model and embodiment are described below in conjunction with the accompanying drawings.

Fig. 1 is embodiment one structural representation of the present utility model, and antetheca is forward.

Fig. 2 is structural representation when rolling on antetheca bottom in Fig. 1.

Fig. 3 is embodiment two structural representation of the present utility model, and rear wall is forward.

Fig. 4 is structural representation when rolling on rear wall bottom in Fig. 3.

Specific embodiment

Referring to accompanying drawing, damping bag with square bottom in present embodiment, its bag material is material the answering using bubble chamber film of bag Condensation material, composite is by bubble film layer and PET, PE, paper（As brown paper）Or aluminium plating membrane is composited, gas on bag , in inner side, PET, PE, paper or aluminizer are in outside for vacuolar membrane.Can also the inner side of bubble chamber film be combined PE layer, make sack more solid, Protect bubble chamber film simultaneously.PE layer and bubble chamber film all can be attached by sealing technique（Seal）.

Bag includes antetheca 1, rear wall 3 and bag bottom 2, and the left and right sides of antetheca 1 is connected with the left and right sides correspondence of rear wall 3 Connect, the bottom of the bottom of antetheca 1 and rear wall 3 is attached by bag bottom 2, bag bottom 2 is to insert bottom structure, bag bottom 2 and antetheca 1 and after Four base angles A, B, C, D that wall 3 is formed are obtuse angle.Damping bag with square bottom has the bag with square bottom of damping effect, and protection well is placed Article in bag, and the base angle of bag is obtuse angle, will not be squeezed formation wedge angle, and bag can steadily stand, will not Thing is had to fall in wedge angle.Can be used for putting of the article such as electric equipment, precision instrument and equipment.Bag bottom is formed with antetheca and rear wall Obtuse angle make antetheca and the bottom of rear wall have inverted trapezoidal structure, inverted trapezoidal structure is wide at the top and narrow at the bottom.Damping bag with square bottom is symmetrical Setting.

The left and right sides of antetheca 1 is connected by corresponding sealing with the left and right sides of rear wall 3.In antetheca and rear wall Bottom, the sealing corresponding with the left and right sides at bag bottom of the left and right sides of antetheca, the left and right sides pair at the left and right sides of rear wall and bag bottom Should seal.

Using broadside sealing, envelope line 4 is more firm for sealing.Envelope line 4 width of broadside sealing is 0.5 ~ 1.5 centimetre.

Bag is by forming antetheca 1 and rear wall 3, the coupling part insert edge inwards of antetheca and rear wall after whole composite material foldable Form the bag bottom 2 of bag bottom, that is, insert bottom structure.Carry out folding by whole material, insert bottom and make convenient, antetheca and rear wall And bag bottom is continuous structure.The side's of being exactly bottom structure is opened at the bag bottom of slotting bottom structure, can be stood, and is folding line in the middle of slotting bottom Line, the square bottom described in present embodiment is not square, is a polygon.

Referring to Fig. 1, Fig. 2, convenient in order to open in use in damping bag with square bottom, antetheca and rear wall with insert The junction at bottom is sealed, and sealing can be processed using broadside envelope line 4, also more firm.I.e. antetheca and bag bottom, Yi Jihou Wall has broadside envelope line 4 additionally it is possible to make antetheca, rear wall be demarcated with slotting bottom with the joining place at bag bottom.

In the present embodiment mode, when manufacturing damping bag with square bottom, entire volume composite is unreeled, the material unreeling out enters Row folds（Obtain antetheca and rear wall）, carry out inserting bottom in junction after folding（Obtain bag bottom structure）, then laterally sealed （Obtain two sides）, then carry out oblique sealing at four base angles and form four obtuse angles, then carry out cutting formation at sealing and subtract Shake bag with square bottom, can also be sealed with the junction at slotting bottom in antetheca and rear wall.
