Description

Technical Field

[0001] This application relates to the field of packaging bag technology, and in particular to an oil-resistant and easy-to-clean packaging bag. Background Technology

[0002] Packaging bags are containers used to wrap, hold, and protect goods. They are usually made of materials such as plastic, paper, metal foil, and fabric, and come in various shapes such as bags and tubes. They are widely used in food, daily necessities, and industrial products, and their main function is to prevent goods from being squeezed, collided, or rubbed during transportation and storage.

[0003] Currently, a Chinese utility model patent application published on July 9, 2024, with publication number CN221294623U, discloses a recyclable and biodegradable plastic food packaging bag. The bag includes a bag body made of biodegradable material. A retaining strap is fixed to the rear bottom of the bag body, a first fixing strap is fixed to the front end of the retaining strap, and second fixing straps are fixed to both ends of the retaining strap. Multiple first snap female buckles are fixed to the side of the first and second fixing straps near the bag body, and first snap female buckles are provided with first snap male buckles near the bag body. This utility model allows users to open and seal the bottom of the bag by detaching and assembling the interconnected first snap female buckles and first snap male buckles. Opening facilitates cleaning and maintenance of the bag's interior, avoiding the inconvenience of cleaning residue and oil stains caused by a single-piece bottom structure in previous designs. Sealing facilitates sealing the interior of the bag's bottom, ensuring the stability of the bag during loading.

[0004] Recyclable and biodegradable plastic food packaging bags in related technologies are used by separating the bottom from the bag body. However, because the bottom is spliced ​​together by three different fixing straps, stains are easily left at the connection between the two fixing bags at the bottom of the bag body and are difficult to clean. Since the gaps and dead corners at the connection of the fixing straps cannot be thoroughly cleaned, even after repeated rinsing, oil stains, sauces and other stains will still remain. Users give up on reuse because they cannot be dried. The original design of recycling becomes a mere formality, and the actual number of uses is far lower than expected.

[0005] Therefore, it is necessary to propose an oil-resistant and easy-to-clean packaging bag to solve the above problems. Utility Model Content

[0032] Recyclable and biodegradable plastic food packaging bags in related technologies are used by separating the bottom from the bag body. However, because the bottom is spliced ​​together by three different fixing straps, stains are easily left at the connection between the two fixing bags at the bottom of the bag body and are difficult to clean. Since the gaps and dead corners at the connection of the fixing straps cannot be thoroughly cleaned, even after repeated rinsing, oil stains, sauces and other stains will still remain. Users give up on reuse because they cannot be dried. The original design of recycling becomes a mere formality, and the actual number of uses is far lower than expected.

[0033] Based on this, in order to improve the technical problems existing in the related technology where packaging bags have gaps and dead corners in terms of cleaning, are prone to residual oil stains, sauces and other stains, and are difficult to clean thoroughly, affecting the hygiene and appearance of the packaging bags and reducing users' willingness to reuse them, the embodiments of this application provide the following solutions.

[0034] Please refer to the following: Figures 1 to 5 This application provides an oil-resistant and easy-to-clean packaging bag. The oil-resistant and easy-to-clean packaging bag includes a bag body 1 and a detachable bottom 2 detachably connected to the bottom of the bag body 1. The detachable bottom 2 is an integral structure and includes an upper half 21 and a lower half 22 that can cooperate to form a bottom closed structure. A raised sealing rib 4 and a grooved sealing rib 41 that cooperate with each other are provided between the upper half 21 and the lower half 22. A rough-surface hook and loop fastener 3 and a barbed hook and loop fastener 31 for fastening are also provided between the upper half 21 and the lower half 22. The raised sealing rib 4 and the grooved sealing rib 41 are located inside the hook and loop fastener.

[0035] The core of the oil-resistant and easy-to-clean packaging bag provided in this application embodiment lies in the design of the removable bottom 2. The removable bottom 2 refers to an independent component at the bottom of the packaging bag, which can be detached from the bag body 1 for easy cleaning. The removable bottom 2 is designed as a one-piece structure, meaning it is a complete component without additional seams, thus avoiding the problem of dirt and grime accumulating in traditional spliced ​​bottoms. The removable bottom 2 further includes an upper half 21 and a lower half 22, which can cooperate with each other to form a closed bottom structure of the packaging bag. This split design allows the removable bottom 2 to be fully unfolded during cleaning, ensuring that every corner can be thoroughly cleaned. The one-piece structure design of the removable bottom 2 avoids the gaps and dead corners caused by traditional splicing methods. Combined with the sealing effect of the raised sealing ribs 4 and the grooved sealing ribs 41, as well as the fastening of the Velcro, oil stains are effectively cleaned, greatly improving the cleaning convenience and hygiene of the packaging bag. The raised sealing ribs 4 and the grooved sealing ribs 41 are provided between the upper half 21 and the lower half 22. The raised sealing rib 4 is a protruding strip structure, while the recessed sealing rib 41 is a recessed strip structure that matches the shape of the raised sealing rib 4. When the upper half 21 and the lower half 22 are closed, the raised sealing rib 4 is tightly embedded in the recessed sealing rib 41, forming a physical barrier that effectively prevents liquids and oils from leaking from the bottom. This sealing rib design can be made of various elastic materials, such as silicone, rubber, or thermoplastic elastomers, to ensure good sealing performance and durability. The upper half 21 and the lower half 22 are tightly attached by Velcro, while the raised sealing rib 4 and the recessed sealing rib 41 interlock to form a double seal. This structure not only provides good sealing performance but also effectively resists external pressure and maintains the stability of the bottom of the packaging bag. When cleaning the packaging bag is required, simply tear open the Velcro, and the upper half 21 and the lower half 22 can be separated, exposing the inner surface of the removable bottom 2. Since the removable bottom 2 is a one-piece structure that can be fully unfolded, users can easily rinse and wipe the inside to ensure thorough removal of oil and residue.

[0036] In this embodiment, a wire 5 is provided inside the detachable bottom 2, and the position of the wire 5 corresponds to the position of the raised sealing rib 4 and the groove sealing rib 41.

[0037] With this design, the presence of wire 5 inside the removable bottom 2, and the fact that the position of wire 5 corresponds to the positions of the raised sealing rib 4 and the grooved sealing rib 41, significantly enhances the structural strength and deformation resistance of the removable bottom 2. The wire 5 strengthens the structural strength and sealing effect of the removable bottom 2, ensuring that the sealing structure is not easily deformed during stress or use, and further improving the oil stain resistance.

[0038] In this embodiment, the bag body 1 has a handle hole 11; it also includes a handle 12 and an abutment post 13; the abutment post 13 passes through the handle hole 11, and the handle 12 is connected to the abutment post 13.

[0039] This design, combining the handle hole 11, the carrying strap 12, and the abutment post 13, provides a convenient way to carry the packaging bag and increases its ease of use.

[0040] In this embodiment, the bag body 1 and the detachable bottom 2 are detachably connected by snap fasteners 6 and snap fasteners 61.

[0041] This design, with the connection between the snap button 6 and the snap nut 61, makes the disassembly and installation of the bag body 1 and the removable bottom 2 more convenient and quick, and facilitates cleaning and replacement.

[0042] In this embodiment, the bag body 1 and the detachable bottom 2 are detachably connected by a first zipper 7 and a second zipper 71.

[0043] This design provides a tighter connection with the zipper, further enhancing the overall sealing and stability of the packaging bag.

[0044] In this embodiment, the bottom of the bag body 1 is provided with the snap button 6; the upper half 21 and the lower half 22 of the detachable bottom 2 are both provided with the snap button female 61.

[0045] This design, with the specific positions of the snap button 6 and the snap nut 61, allows the detachable bottom 2 to be more securely connected to the bag body 1, improving the overall sturdiness.

[0046] In this embodiment, the bottom of the bag body 1 is provided with the first zipper 7; the outer edges of the upper half 21 and the lower half 22 of the detachable bottom 2 are connected with the second zipper 71.

[0047] This design, with the zipper positioned specifically, makes the connection between the bag body 1 and the removable bottom 2 tighter, further improving the sealing effect and anti-fouling ability.

[0048] In this embodiment, the hook and loop fastener includes a rough hook and loop fastener 3 disposed on the upper half 21 and a sharp hook and loop fastener 31 disposed on the lower half 22.

[0049] This configuration, with the combination of the rough-surface hook and loop fastener 3 and the barbed-surface hook and loop fastener 31, provides a reliable fastening effect, ensuring that the upper and lower halves 22 of the removable bottom 2 fit tightly and prevent loosening.

[0050] In this embodiment, the textured hook and loop fastener 3 is a strip structure, and the barbed hook and loop fastener 31 is a strip structure.

[0051] This design, with its strip-shaped hook and loop fasteners, increases the contact area of ​​the fasteners, further enhancing the strength and stability of the fastening.

[0052] In this embodiment, the upper half 21 is provided with the groove sealing rib 41, and the lower half 22 is provided with the protruding sealing rib 4.

[0053] This specific arrangement of the groove sealing rib 41 and the raised sealing rib 4 allows them to work together better to form a more effective sealing structure, further enhancing the ability to prevent oil stains.

[0054] The working principle of the oil-resistant and easy-to-clean packaging bag provided in this application embodiment is as follows: The removable bottom 2 is designed as a single piece, allowing for easy removal and detachment from the bag body 1.

The upper part 21 has rough-surface hook and loop fasteners 3 on both ends, while the lower part 22 has barbed hook and loop fasteners 31 on both ends. The rough-surface hook and loop fasteners 3 and barbed hook and loop fasteners 31 are designed as a single strip, reducing gaps and improving sealing. Additionally, the upper part 21 has grooved sealing ribs 41 on both ends, which seal against the raised sections on both ends of the lower part 22. The ribs 4 interlock to form a double seal of physical barrier and hook and loop fastener, preventing oil stains from seeping out from the gaps in the hook and loop fastener. At the same time, the groove sealing ribs 41 and the raised sealing ribs 4 are set inside the hook and loop fastener 3 and the hook and loop fastener 31 to reduce possible damage to the hook and loop fastener by oil stains. The removable bottom 2 and the bag body 1 can be connected by snap fasteners 6 and snap fasteners 61, or by the interlocking of the first zipper 7 and the second zipper 71, which facilitates the disassembly of the two and thus better cleans the packaging bag and avoids oil stains. Inside the removable bottom 2, at positions corresponding to the groove sealing rib 41 and the raised sealing rib 4, wires 5 are provided to reduce the probability of the removable bottom 2 being stretched open when a large object is put into the bag body 1. A handle hole 11 is provided on the bag body 1. An abutment post 13 is inserted into the handle hole 11. The handle 12 can be detachably installed on the bag body 1 through the cooperation of the abutment post 13 and the handle hole 11, so as to facilitate the removal and cleaning of the bag body 1.
