Description

Packaging bag

Technical Field

The utility model relates to the field of packaging, specifically a packaging bag.

Background

Chinese patent document CN207658313U discloses an "anti-private-dismantling express package structure" in 2017, 7/27, which includes a package, an express information sheet, and an anti-counterfeit adhesive tape, where the anti-counterfeit adhesive tape includes a base layer and an adhesive layer coated on the lower surface of the base layer, and the adhesive layer is provided with an anti-counterfeit mark capable of prompting whether the adhesive layer is uncovered; the anti-counterfeiting adhesive tape crosses and bonds two sides of the seal of the packing material. The applicant declares that the beneficial effects of the utility model are: the package can be reused with low cost and high efficiency, and the function of preventing the private dismantling is provided on the basis. The overall volume of the package is not compressible due to the lack of adaptive folding effect of the package provided by this solution for different sizes of contents. During storage and transportation, the large volume affects the efficiency and cost of storage and transportation. In addition, earlier seal both sides at the sack with anti-fake sticky tape, paste express delivery information list to anti-fake sticky tape on again, the action is repeated, and efficiency is not high.

SUMMERY OF THE UTILITY MODEL

Based on the above problems, the present invention is directed to a packaging bag, which can better adapt to the shape and size of the contents, and effectively compress the overall volume of the package.

The packaging bag comprises a bag body and a reusable connecting pair, wherein the bag body comprises a flexible lower layer fabric and an upper layer fabric, the top of the bag body is open, and the lower layer fabric and the upper layer fabric are connected with each other at the three sides of the bottom, the left side and the right side; connect vice for the flexible material or the rigidity material of intermittent type setting, it is vice to include to connect: the first connecting pieces are positioned on the left side and the right side of the surface of the upper layer fabric and extend along the directions of the sides; the connecting pair also comprises a second connecting piece which is arranged on the top of the lower layer of fabric and the upper layer of fabric and is used for forming a seal; when the bag body is turned over in a mode that the upper layer fabric is opposite, one part of the first connecting piece can be in adaptive connection with the other part of the first connecting piece.

Particularly, the connecting pair is a magic tape or a plurality of self-adhesive tapes or zippers which do not divide a male surface and a female surface.

Particularly, a flanging is formed at the top of the lower layer of fabric, and the second connecting piece positioned on the flanging is in fit connection with the second connecting piece positioned on the inner surface or the outer surface of the upper layer of fabric.

Particularly, the inner surface or the end part of the top part of the lower layer fabric is provided with a second connecting piece, and the second connecting piece positioned on the inner surface or the end part of the top part of the lower layer fabric is in fit connection with the second connecting piece positioned on the inner surface or the end part of the upper layer fabric.

In particular, an RFID chip is fixed inside the packaging bag.

The packaging bag designed by the technical scheme only comprises a bag body and a reusable connecting pair. The shape of the bag body can be freely selected, and is generally rectangular. The connecting piece is made of flexible material, such as magic tape, multi-time adhesive sticker and zipper, or rigid material with discontinuous arrangement, such as snap fastener. Because the upper and lower layers of fabrics are flexible, the bag body can be folded according to different sizes of contents, so that the volume is compressed; due to the design of the connecting pair, different folding states can be adapted. For the purpose of rain and moisture prevention, the lower fabric and the upper fabric can be generally selected from non-woven fabrics, polyurethane material sheets and the like which are subjected to coating treatment, so that the bag body can resist external rainwater and liquid leakage of internal contents, and the service life of the packaging bag is greatly prolonged.

Preferably, the connecting pair is a magic tape. The magic tape is used as a connecting pair, so that the installation is simpler, the vision is more visual, and the operation steps are more convenient.

Preferably, the RFID chip is fixed in the package. When this wrapping bag is used as the express delivery bag, perhaps when being specific part transport container in the manufacturing enterprise, cooperation RFID chip identification system, the wrapping bag of this scheme design can be discerned when passing through each RFID chip identification point, is convenient for master the position of this wrapping bag, also is convenient for retrieve on intelligent packing recycle device.

To sum up, the beneficial effects of the utility model are that: the shape and the size of adaptation content that the wrapping bag can be better, effectively compress the whole volume of packing.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Example 1

Example 1 is a package consisting of a bag body and a reusable coupling pair. As shown in fig. 1, the bag of this example is rectangular in shape and is formed by connecting a flexible lower layer fabric 1 and an upper layer fabric 2 to each other in the lower, left, and right directions, and the opening of the bag is located above. The part of the upper side of the lower fabric, which is longer than the upper fabric, forms a flanging 3. The connecting pair of the embodiment is a magic tape 4 which is a novel magic tape, and the hook tape does not have a male surface and a female surface, and all positions of the binding surface are provided with hooks and bristles. But those skilled in the art can also use a plurality of stickers or zippers instead of the velcro tapes. The magic tapes are fixed on the left and right sides of the surface of the turned-over edge and the left and right sides of the surface of the upper layer fabric respectively and extend along the up-down direction of the sides. As shown in fig. 2, when the contents are placed in the bag body, the bag body can be matched with the shape and size of the contents to turn over the redundant parts, and when the turnup is turned over above the upper fabric, the binding surfaces of the magic tapes can be mutually stuck, so that the bag opening can be sealed, and the bag body can be kept in a volume compression state.

The upper and lower fabrics of this example were made of polyurethane sheeting. An RFID chip 5 is fixed in the packaging bag and can be read by an RFID chip reading device.

Fig. 3 is a schematic view showing the state where the packaging bag is turned over again with the upper sheets facing each other. For example, after the bag body is sealed in such a manner that the turnup is turned over above the upper fabric and the first connecting piece and the second connecting piece of the connecting pair are connected, the bag body can be turned over again in such a manner that the upper fabric is opposed to each other, so that a part of the first connecting piece can be connected to another part of the first connecting piece. Therefore, the packaging bag can be fixed and adjusted in size, the content of the packaging bag is not easy to fall out, and a better dustproof and waterproof effect is achieved.

It should be understood that the above embodiments of the present invention are not intended to limit the solution of the present invention, and for example, the sealing of the upper layer fabric and the lower layer fabric may be performed in other manners, such as by using the top or the end of the upper layer fabric and the end of the lower layer fabric without providing the turned edge.
