Detailed Description

The present application is described in further detail below with reference to figures 1-3.

Example 1:

the embodiment of the application discloses a packaging bag. Referring to fig. 1 and 2, a packaging bag comprises a bag body 1 and a cover body 2, wherein a folding edge 11 is arranged on the outer wall of the bag body 1, the bag body 1 realizes the conversion between a three-dimensional shape and a flat shape through the folding edge 11, meanwhile, the top of the bag body 1 is arranged in an opening mode, and the bag body 1 is used for containing articles. Correspondingly, the cover body 2 is rectangular, a long side of the cover body 2 is fixed to the top edge of the bag body 1, the cover body 2 and the bag body 1 are integrally formed, the cover body 2 can rotate relative to the bag body 1, the cover body 2 is provided with a fixing component 3, and the fixing component 3 is used for achieving relative fixing between the free end of the cover body 2 and the bag body 1.

Further, the inside fagging (not shown in the figure) that is provided with of bag body 1, the fagging is the setting of cuboid form, and the internal stay board is placed in the inside of bag body 1, and the outer wall of internal stay board cooperates with the inner wall butt of the bag body 1 for the internal stay board can prop up the inside of the bag body 1, in order to improve the structural strength of the bag body 1.

In addition, the peripheral wall of the bag body 1 is formed by enclosing and pasting paper sheets, and the bonding seam of the bag body 1 is positioned on the outer wall corresponding to the inwards concave space of the bag body 1, so that the bonding seam is hidden, and the condition that the bonding seal is exposed outside and the overall flatness of the outer wall of the bag body 1 is influenced is reduced.

Specifically, fixed subassembly 3 includes connecting band 31 and fixed block 32, and connecting band 31 is fixed in the surface of lid 2, and a plurality of bayonets 12 have been seted up to the lateral wall that lid 2 was kept away from to bag body 1, and a plurality of bayonets 12 set up along the length direction interval of bag body 1, and connecting band 31 snakelike winding is located between two adjacent bayonets 12, and fixed block 32 runs through bayonet 12 in proper order.

The user puts into article in the bag body 1, top involution with the bag body 1 through the hand, upset lid 2, lid 2 lid fits the top of the bag body 1, wear to establish two adjacent bayonets 12 with fixed block 32 in proper order, so that connecting band 31 snakelike around locating between two adjacent bayonets 12, in this process, when the object that loads in the bag body 1 is more, the range that the open-top of the bag body 1 propped open is bigger, the regional relative strain that the opening of the bag body 1 occupy lid 2 is many, because the length of connecting band 31 and lid 2 is limited, penetrate two nearer bayonets 12 departments with fixed block 32, so that fixed subassembly 3 can normally realize the fixed action to lid 2 and bag body 1, and then improved the structural stability who does not know.

Further, the cover body 2 is double-layer, a cutting opening 21 is formed in the surface of the cover body 2, the cutting opening 21 is matched with the connecting belt 31 in shape, and the connecting belt 31 and the cover body 2 are integrally formed. Make the wrapping bag when production, with cardboard fifty percent discount formation lid 2, the mouth 21 is cut out to the rethread cutting tool, has also formed connecting band 31 simultaneously, bonds cardboard formation connecting band 31 with the outside and compares, and the connecting band 31 that this mode formed is owing to set up with lid 2 integrated into one piece, and consequently joint strength between the two is higher, and the structure is more stable, has also practiced thrift the shaping time simultaneously.

Meanwhile, the end of the fixing block 32 is arranged in a round angle to play a guiding role, so that the fixing block 32 can more conveniently penetrate through the bayonet 12.

The implementation principle of a wrapping bag of this application embodiment 1 does: the user puts into article in the bag body 1, top involution with the bag body 1 through the hand, upset lid 2, lid 2 lid fits the top of the bag body 1, wear to establish two adjacent bayonets 12 with fixed block 32 in proper order, so that connecting band 31 snakelike around locating between two adjacent bayonets 12, in this process, when the object that loads in the bag body 1 is more, the range that the open-top of the bag body 1 propped open is bigger, the regional relative strain that the opening of the bag body 1 occupy lid 2 is many, because the length of connecting band 31 and lid 2 is limited, penetrate two nearer bayonets 12 departments with fixed block 32, so that fixed subassembly 3 can normally realize the fixed action to lid 2 and bag body 1, and then improved the structural stability who does not know.

Referring to fig. 3, the difference from embodiment 1 is that a packaging bag includes a bag body 1, the top of the bag body 1 is provided with an opening, an adjusting component 4 is provided on the bag body 1, the adjusting component 4 includes an elastic sleeve ring 41 and a lifting ring 42, the elastic sleeve ring 41 is movably sleeved on the outer wall of the bag body 1, and the lifting ring 42 is fixed on the side wall of the elastic sleeve ring 41. In this embodiment, the elastic collar 41 is made of rubber with certain elasticity, and the lifting ring 42 and the elastic collar 41 are integrally formed.

Specifically, the activity of the elastic sleeve ring 41 is cup jointed in the outer wall of the bag body 1, and under the elastic acting force of the elastic sleeve ring 41, the opening of the bag body 1 is squeezed and closed, and simultaneously, the position that the elastic sleeve ring 41 is relative is adjusted to the accessible, and then the closed region of the bag body 1 is adjusted to the volume that the bag body 1 is inside to hold articles, the user still can conveniently carry through the lifting ring 42 and take this wrapping bag.

Simultaneously, the bail 42 sets up for integrated into one piece with the elastic lantern ring 41, and both accessible same mould output has indirectly improved production efficiency when producing.

In addition, the bottom of the bag body 1 is provided with the magic tapes 13, the magic tapes 13 are fixed with the bag body 1 in a bonding mode, the magic tapes 13 are positioned on two sides of the bottom of the bag body 1, when the bag body 1 is flat, the magic tapes 13 on two sides of the bottom of the bag body 1 are mutually attached, and the magic tapes 13 are pulled down mutually so that the shape of the bag body 1 can be more stable.

The implementation principle of embodiment 2 of the present application is substantially the same as that of embodiment 1, and will not be described herein again.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
