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.

[0004] FFC (Flexible Flat Cable) offers advantages such as small size, light weight, good flexibility, compact structure, and excellent electrical reliability. Because it can be easily moved, bent, and twisted without damaging the conductors, it has high assembly reliability and quality, making it widely used for low-voltage signal connections between moving parts and PCB boards, and in miniaturized electrical equipment.

[0005] FFC flexible cables are mainly composed of insulating films on both sides and a middle conductor. Reinforcement plates are usually installed at the contacts. In addition to common specifications, parameters such as the number of conductor cores, spacing, and length can also be customized. In addition, the contact structures at both ends can be further divided into 15 custom specifications based on whether the metal contacts are on the same side, whether both sides of the contacts are fully exposed, whether a reinforcement plate is installed, whether the reinforcement plate is directly attached to the conductor or the insulating film, and whether half of the reinforcement plate is tilted. Summary of the Invention

[0006] The object of the present invention is to provide a type of card head bag that can be used to easily install a flexible flat cable so that external devices that move relative to each other can be connected to electronic components in the card head bag.

[0007] To achieve the above-mentioned purpose, the present invention provides a clamping head bag for accommodating a flexible flat cable, comprising: a clamping head and a product bag. The clamping head and the product bag differ from the traditional clamping head bag mainly in the clamping head and the hot-sewing part.

[0008] The hot seam skips several steps near the intersection with the planned installation of the flexible flat cable, leaving an inner hole of a certain width. The width of the inner hole is slightly wider than the width of the flexible flat cable to be installed, so that the flexible flat cable can easily pass through the inner hole from the product bag into the clamp.

[0009] The clamping head punches a hole near the expected installation position of the flexible flat cable. The diameter of the punched hole is slightly larger than the width of the flexible flat cable to be installed, so that the flexible flat cable can easily pass through the clamping head.

[0010] The clamping head further pressurizes semi-constrained heat seam edges on both sides of the line connecting the inner hole of the heat seam and the clamping head outlet hole to guide the direction of the flexible cable in the clamping head. The inner side spacing of the semi-constrained heat seam edges on both sides is also slightly larger than the width of the flexible cable to be installed.

[0011] The beneficial effects of the present invention are: A. It is easy to insert and install the semi-processed flexible flat cable from the product bag, and can continue to process the flexible flat cable after passing through the clamp head; B. The flexible cable still has sufficient rotational freedom and flexibility after passing through the mounting clip pocket; C. When the flexible cable rotates or twists after passing through the mounting clip pocket, the semi-constrained heat seam guides the cable inside the clip pocket, protecting the clip edge heat seam and reducing damage caused by traction and collision. At the same time, the degree of failure of the semi-constrained heat seam also serves as a warning for the life of the clip edge heat seam. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] 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.

[0017] As shown in the figure, a head bag for holding a flexible flat cable 7 includes a head 1 and a product bag 3. The flexible flat cable is planned to be laid on the right side near the edge of the bag.

[0018] In a specific embodiment, the present invention provides a clamping head bag for accommodating a flexible flat cable 7. The clamping head boundary heat seam line 2 and the intersection of the planned flexible flat cable 7 are not subjected to a press seam heat treatment, and an inner hole 6 slightly wider than the width of the planned flexible flat cable 7 is left empty.

[0019] In a specific embodiment, the head bag is punched with a hole 4 at a position above and to the right of the head 1 and facing the inner hole 6 . The diameter of the hole 4 is slightly larger than the width of the flexible flat cable 7 to be installed.

[0020] In a specific embodiment, the card head bag card head 1 is further pressurized with two hot seams on both sides of the line connecting the hot seam inner hole 6 and the card head outlet hole 4 as semi-constrained hot seam edges 5, and the inner side spacing of the pressed semi-constrained hot seam edges 5 is slightly larger than the width of the flexible cable 7 to be installed.

[0021] Furthermore, when the planned installation of the flexible flat cable 7 requires processing and fixing other attachment components in the middle section or at both ends, the middle section and the end away from the clamping head 1 after the planned installation can be processed outside the clamping head bag first, and then loaded into the product bag 3 from the seal 31, and passed through the inner hole 6, the semi-constrained heat seam edge 5, and the hole 4 in sequence, and finally the end of the flexible flat cable 7 that is passed through the outside of the clamping head 1 can be processed.

[0022] Furthermore, when it is necessary to install the flexible flat cable 7 in the inverted clamp bag, the end close to the clamp 1 after the planned installation is also not processed first. After the product bag 3 is loaded into the bag through the seal 31, the seal 31 is kept unfolded, the clamp 1 is folded back, and the flexible flat cable 7 is folded back and passed through the inner hole 6, the semi-constrained heat seam edge 5, and the outlet hole 4. After that, the clamp 1 and the flexible flat cable 7 are restored and the seal is closed. At this time, the protruding end of the flexible flat cable 7 that is loaded into the inverted clamp bag and stretched can be processed.

[0023] Furthermore, when the extended section of the soft flat cable 7 extending out of the card head bag from the through hole 4 moves and twists with other external components, the torsional amplitude and pulling force of the extended section inside the card head bag will be greatly weakened due to the guiding and restraining effect of the through hole 4 and the semi-constrained heat seam edge 5, which greatly reduces the destructive force on the card head boundary heat seam 2 and the inner hole 6.

[0024] The above describes in detail the flexible cable holder provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are intended only to facilitate understanding of the present invention's methods and core concepts. 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.
