Detailed Implementation
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0036] like Figures 1 to 3 As shown, Figure 1 A schematic diagram of the overall structure of the food packaging bag provided in this application embodiment, with the inner bag and outer bag in a combined state; Figure 2 A schematic diagram of the overall structure of the food packaging bag provided in the embodiment of this application, with the inner bag and outer bag in a first split state; Figure 3 This is a schematic diagram of the overall structure of the food packaging bag provided in the embodiments of this application, with the inner bag and outer bag in a second split state.
[0037] This application provides a food packaging bag 10, including an outer bag 11 and an inner bag 12.
[0038] Among them, outer bag 11 is a breathable bag.
[0039] Specifically, the outer bag can be made of various breathable bags that are currently available or will be developed in the future, such as bags made of breathable materials (e.g., non-woven fabric, breathable cotton, gauze); or breathable holes can be set in the bag body to achieve the breathable function.
[0040] Inner bag 12 is a resealable bag.
[0041] Specifically, the sealed bags can be various existing or future food-grade sealing bags, such as PE sealing bags.
[0042] The inner bag 12 is disposed inside the outer bag 11 and is detachably connected to the outer bag 11 via a first connecting structure 13.
[0043] This embodiment of the application employs a two-layer detachable structure of an outer bag and an inner bag, with the outer bag being a breathable bag and the inner bag being a sealed bag. This facilitates better phased preservation of foods such as bread, helping to extend the shelf life of these foods. For example, bread from a typical household oven is hot and needs to cool down, but it cannot be exposed to air (to prevent rodents and insects). At this time, the bread can be placed in a separate breathable bag (outer bag) and stored for 2-3 days. After the bread has completely cooled and absorbed nutrients and moisture, the inner bag is assembled with the outer bag, and the bread is placed in the sealed bag (inner bag). The sealed container is then placed in the refrigerator (to prevent moisture evaporation). This way, the bread remains soft and does not mold, which helps to extend the food's shelf life.
[0044] Furthermore, the detachable connection between the sealing bag and the breathable bag allows for easy cleaning of both, and facilitates thorough cleaning of the sealing bag, which comes into direct contact with food. For example, the inner bag that comes into contact with food can be removed and cleaned directly, making cleaning convenient and ensuring a thorough clean.
[0045] In addition, since the sealed bag and the breathable bag are detachably connected, the outer bag and the inner bag can be used separately. For example, the outer bag can be used as a shopping bag, thereby increasing the uses of food packaging bags and improving their utilization rate.
[0046] Continue as Figure 2 and 3 As shown, in an optional embodiment, the first connection structure 13 includes a male snap 131 and a female snap 132 that cooperate with each other.
[0047] One of the male snap 131 and the female snap 132 is disposed on the inner wall of the outer pocket 11; the other of the male snap 131 and the female snap 132 is disposed on the outer wall of the inner pocket 12.
[0048] The embodiments of this application employ mutually cooperating male snap 131 and female snap 132 as the first connecting structure, which has the advantages of low cost, easy assembly into outer and inner bags, and easy quick assembly and disassembly between outer and inner bags.
[0049] In an optional embodiment, the first connection structure includes: a hook and a loop that cooperate with each other (figures omitted).
[0050] One of the hooks and the loops is located on the inner wall of the outer bag; the other of the hooks and the loops is located on the outer wall of the inner bag.
[0051] The embodiments of this application employ mutually cooperating hooks and hanging rings as the first connecting structure, which has the advantage of facilitating quick assembly and disassembly of the outer bag and inner bag.
[0052] In an optional embodiment, the first connection structure may include: a male hook and a female hook and loop fastener that cooperate with each other (figures omitted).
[0053] One of the male and female hook and loop fasteners is located on the inner wall of the outer bag; the other of the male and female hook and loop fasteners is located on the outer wall of the inner bag.
[0054] The embodiments of this application, by employing mutually cooperating male and female hook and loop fasteners, have the advantage of facilitating quick assembly and disassembly between outer and inner bags.
[0055] In an optional embodiment, the first connection structure may include: a first magnet and a second magnet that can attract and engage with each other (figures omitted).
[0056] One of the first magnet and the second magnet is disposed on the inner wall of the outer bag; the other of the first magnet and the second magnet is disposed on the outer wall of the inner bag.
[0057] The embodiments of this application, by employing a first magnet and a second magnet that can attract and cooperate with each other, have the advantage of facilitating quick assembly and disassembly between the outer bag and the inner bag.
[0058] It should be noted that, apart from the first connecting structure listed in the above embodiments, any structure that can achieve a detachable connection between the inner bag and the outer bag is within the scope of protection of this application.
[0059] Continue as Figure 2 and 3 As shown, in an optional embodiment, the first connecting structure 13 is disposed at the bag opening end of the inner bag and the outer bag.
[0060] In this embodiment, the first connecting structure 13 is positioned at the opening of the inner and outer bags, which facilitates the user's disassembly and assembly of the inner and outer bags during use. Alternatively, the first connecting structure 13 can be positioned at any corresponding position on the inner and outer bags as needed.
[0061] Continue as Figure 1 As shown, in one embodiment, the outer bag 11 is also provided with a handle structure 14 at the bag opening end.
[0062] The embodiments of this application, by setting a handle structure, make it convenient for food packaging bags to be carried on one's person or hung in any desired location.
[0063] In addition, when the outer bag is used alone, the handle structure allows it to be used as a supermarket shopping bag and for various outdoor items, further increasing the versatility of the food packaging bag.
[0064] In an optional embodiment, the handle structure 14 includes: a first connecting strap 141 and a second connecting strap 142;
[0065] The first end of the first connecting strap 141 is fixedly connected to the first end of the bag opening of the outer bag 11;
[0066] The first end of the second connecting strap 142 is fixedly connected to the second end of the bag opening of the outer bag 11;
[0067] The second end of the first connecting strip 141 and the second end of the second connecting strip 142 are detachably connected via the second connecting structure 143.
[0068] like Figures 2 to 4 As shown, Figure 4 This is an enlarged overall structural diagram of the second connection structure provided in an embodiment of this application.
[0069] In an optional embodiment, the second connection structure 143 includes a locking ring 1431 and a latch 1432 that cooperate with each other. The locking ring 1431 includes an outer ring 14311 and an elastic portion 14312; the latch 1432 includes a bottom portion 14322 and a snap-fit portion 14321.
[0070] The elastic part 14312 is located inside the outer ring 14311 and can deform along the height direction H. For example, the elastic part 14312 can be a sheet structure made of elastic material (such as plastic), and one end of the sheet structure corresponding to the latch is connected to the inner wall of the outer ring 14311.
[0071] The bottom 14322 and the latching part 14321 are symmetrically arranged vertically along the height direction H; a receiving cavity adapted to the locking ring 1431 is formed between the bottom 14322 and the latching part 14321; a through hole adapted to the elastic part 14312 is formed in the latching part 14321.
[0072] The height of the accommodating cavity is such that when the locking ring 1431 is inserted into the accommodating cavity, the elastic part 14312 undergoes compression deformation along the height direction H.
[0073] When the locking ring 1431 is inserted into the receiving cavity, the elastic part 14312 deforms under the pressure applied by the bottom surface of the latching part 14321 to form an elastic force. When it reaches the position corresponding to the through hole, it passes through the through hole based on the elastic force, thereby forming a locking and limiting relationship with the inner wall of the through hole in the lateral direction L, so as to realize the connection between the latch and the locking ring. When separation is required, the elastic part 14312 is pressed towards the bottom 14322 in the height direction H, so that the elastic part 14312 disengages from the positioning effect of the through hole of the latching part 14321 in the height direction, and then the locking ring 1431 is stretched away from the receiving cavity, thereby realizing the separation of the locking ring 1431 and the latch 1432.
[0074] In an optional embodiment, the end of the elastic portion 14312 away from the latching portion 14321 along the height direction also forms a latching structure adapted to the through hole (not shown due to obstruction).
[0075] In this embodiment, since the end of the elastic part 14312 away from the snap-fit part 14321 in the height direction forms a snap-fit structure, it can effectively prevent the elastic part 14312 from disengaging from the through hole in the height direction H.
[0076] This application embodiment uses a locking ring 1431 and a latch 1432 structure that cooperate with each other. Since the separation between the two relies on the application of force in the height direction, the connection between the first connecting belt and the second connecting belt can still be guaranteed even when a large relative separation force is generated between the first connecting belt and the second connecting belt.
[0077] It should be noted that the second connection structure can adopt various existing or future-developed structures that enable detachable connections. For example, it can also adopt the specific structure of the first connection structure described in the above embodiments, which will not be repeated here. The second connection structure can adopt the same or different detachable connection structure as the first connection structure, all of which fall within the scope of protection of this application.
[0078] In this embodiment, the first connecting strap and the second connecting strap are detachably connected by a second connecting structure. When the first connecting strap and the second connecting strap are connected together by the second connecting structure, they can form a handle structure for the packaging bag, which facilitates carrying and hanging the food packaging bag. When it is not necessary to carry or hang the food packaging bag, the first connecting strap and the second connecting strap can be separated, which makes it convenient to take out and place the food inside, thus improving the convenience of using the food packaging bag.
[0079] Continue as Figure 3 As shown, in an optional embodiment, the outer bag has a sealing structure 15 (e.g., a zipper) at the bag opening.
[0080] This application embodiment effectively prevents items placed inside from falling out by setting a sealing structure at the opening of the outer bag.
[0081] In an optional embodiment, the sealing bag is a transparent sealing bag.
[0082] This application embodiment uses a transparent sealing bag, which makes it easy to observe the type and quality of the food inside the food packaging bag.
[0083] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this application's specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the scope of patent protection of this application.
