Double-clamping-head bag

Abstract

The invention discloses a double-clamping-head bag which is characterized in that clamping heads are arranged at the two ends of a product bag, and a seal of the product bag is arranged at the clamping head at one end. The two clamping heads can be distinguished through different punched holes, the double-clamping-head bags can be connected through the clamping heads at the two ends of the double-clamping-head bags and the light connecting pieces according to the needed topological structure, and when a single double-clamping-head bag is hung, objects needing to be hung can be hung on the other clamping head.

Description

Technical Field

[0001] The present invention relates to a small packaging bag, in particular to a special-purpose packaging bag. Background Art

[0002] A common small commodity packaging bag on the market, the card bag is primarily made of polypropylene (PP, CPP, OPP). A heat-stitched seam is pressed horizontally across the top of the ordinary packaging bag, dividing the bag into two compartments: the card and the product bag. The card can be interlayered with pearlescent film or directly printed with advertising information. After punching, the card can also be attached with hooks for easy binding, stacking, and retrieval. After the card is extruded using the thermoplastic properties of polypropylene, heat-stitched seams can be applied to the product bag to create two or more compartments for storing items. This is known as a card bag (also known as a mother-and-child card bag). Furthermore, the thermoplastic adhesive properties of polypropylene can be used to create a seal at the card's heat-sealed line, with the product bag opening located at the card, creating an inverted card bag (also known as an inverted card bag or inverted bag). Card bags are low-cost, easy to mass-produce, and convenient and flexible to use. They are commonly used in packaging for small commodities, publishing, clothing, daily necessities, and cultural supplies, among other industries.

[0003] my country has a limited number of patent applications for cardboard bags. Chinese Patent Application No. 202030749364.6, "Balloon Packaging Bag (Happy Birthday Laser Cardboard Bag)," and Chinese Patent Application No. 202030711338.4, "Balloon Packaging Bag (Laser Cardboard Bag)," are both design patents. Chinese Patent Application No. 20202078256.0, "A Semi-Automatic Binding Device for Cardboard Bags," is a peripheral device used when cardboard bags are in use. Chinese Patent Application No. 20191014269.2, "A Fully Automatic Cardboard Cardboard Bag Processing Machine," and Chinese Patent Application Nos. 20181016171.0 (Invention) and 20182027445.2 (Utility Model), "A Fully Automatic Cardboard Cardboard Bag Manufacturing System," all relate to processing and manufacturing machines or systems for cardboard bags. However, there are relatively few innovative invention patents for cardboard bags themselves. In some special application scenarios such as special equipment, new types of card head bags are designed based on the advantages of the card head bag structure concept, which can continue to give play to the advantages of low cost, ease of use and flexibility while meeting specific needs. Summary of the Invention

[0004] The purpose of the present invention is to provide a type of packaging bag that can be conveniently equipped with hooks at the upper and lower ends of the product bag, so that packaging bags that need to be hung in series in the same group can be conveniently disassembled and assembled at the clamping heads of each packaging bag through the additional hooks, thereby realizing easy addition or reduction of the series packaging bag group.

[0005] To achieve the above-mentioned purpose, the present invention provides a double-header bag comprising: an A-header, a product bag, and a B-header.

[0006] The A-clip and the product bag still have the same structure as the traditional clip bag. The inner side of the seal of the product bag is adhered with a self-adhesive strip, which can be used to fold the seal inwards and then seal the product bag.

[0007] The B-clip is located outside the seal of the product bag, and the structural relationship between "B-clip-product bag seal" is the same as the structural relationship between "clip-product bag seal" of the inverted seal clip bag.

[0008] Both the A clamp head and the B clamp head can be punched according to the needs of the user, and different shapes can be selected to punch the two clamp heads to distinguish the directions.

[0009] The beneficial effects of the present invention are: A. Use lightweight connectors such as hooks and buckles to connect multiple double-header bags end to end, thus forming a chain group; B. Using lightweight connectors such as hooks and buckles, multiple double-head bags can be connected in parallel to form a double-layer group or a multi-layer group, or closed to form a ring group or even a network combination; C. In addition to connecting and mounting double-head bags, other required items (such as advertisements, decorations, etc.) can also be mounted on any of the punching holes of the head under the condition of meeting the gravity load. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a double-clip bag of the present invention in which the punching holes of A and B clips are the same.

[0011] Figure 2 The invention discloses a double-clip bag in which the punching holes of A and B clips are different.

[0012] Figure 1 、 Figure 2 middle: 1-A card head, 11-A card head punching, 2-product bag, 21-sealing, 22-adhesive strip, 3-B card head, 31-B card head punching, 4-hot stitching. DETAILED DESCRIPTION

[0013] The present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only some, not all, of the embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0014] As shown in the figure, a double-header bag includes an A-header 1, a product bag 2, and a B-header 3. Both the A-header 1 and the B-header 3 can be punched according to the user's required parameters such as the shape, number, and position of the openings, thereby obtaining the A-header punching hole 11 and the B-header punching hole 31. The product bag 2 is sealed 21 with a self-adhesive strip 22 pasted on the inside, and the product bag 2 is separated from the A-header and the B-header by hot stitches 4.

[0015] In a specific embodiment, the seal 21 of the double-head bag provided by the present invention is provided at one end of the B-head 3 , the opening of the product bag 2 is on the inner side of the seal 21 , and the B-head 3 is on the outer side of the seal 21 .

[0016] In a specific embodiment, the A-head punching holes 11 and the B-head punching holes 31 can be set to asymmetric parameters such as different shapes or numbers, which can facilitate distinguishing the sealing end 21 of the product bag or the direction of the product bag 2 at a distance.

[0017] Furthermore, the product bag 2 can be divided again with a new heat-sealing line according to the required proportion and shape to obtain two or more space bag cavities, thereby obtaining a mother-and-child double-head bag.

[0018] Furthermore, when in use, the double-head bag can be combined in series and parallel, closed-loop connected, and mixed networked through lightweight connectors such as hooks and buckles, so as to facilitate connecting the installed units according to the required topology; when a single double-head bag is used, the required mounting items can also be mounted on the lower end head.

[0019] The above describes in detail the double-head bag provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art who utilize the present invention in this and other fields may make various improvements and modifications to the present invention without departing from the principles of the present invention. Such improvements and modifications also fall within the scope of protection of the claims of the present invention.
