Abstract
Description
Technical Field
[0001] This utility model relates to the field of bread packaging box technology, and more specifically to a packaging box for sliced bread. Background Technology
[0002] Packaging boxes for sliced bread are typically designed to protect the bread's freshness, prevent it from getting damp or damaged, and facilitate transportation and storage.
[0003] When sliced bread is packaged in a box, the moisture in the bread is not easily released in the enclosed environment, causing the bread slices to become damp and stick together, which may lead to the problem of bread slices sticking together. To address this issue, a proposal has been made [Publication (Announcement) No.: CN113859736A, A Packaging Box for Sliced Bread], which states that "the setting of placement grooves and support strips facilitates the stepped placement of sliced bread, facilitates the partitioned placement of sliced bread, and ultimately facilitates the subsequent use of sliced bread";
[0004] Although the aforementioned packaging box is designed with compartments for placement, the separation is weak, and when placing thicker or larger breads, they still tend to stick together. In addition, the packaging box uses a single integrated design for the body and lid, which may result in poor control over the moisture generated (i.e., excessive ventilation may cause the bread to dry out, while insufficient ventilation may cause internal moisture to accumulate, affecting the taste). Utility Model Content
[0005] The purpose of this utility model is to provide a packaging box for sliced bread in order to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] This utility model proposes a packaging box for sliced bread, including a bottom cover and an upper cover that is attached and fixed thereon, with an accommodating cavity formed between the bottom cover and the upper cover.
[0008] The accommodating cavity is provided with multiple sets of partition components that are fixed to the bottom cover. The multiple sets of partition components divide the accommodating cavity into multiple compartments for storing sliced bread, and the sliced bread in the multiple compartments do not come into contact with each other.
[0009] It also includes several sets of through holes on the top cover, and a waterproof and breathable membrane layer that is attached and fixed to the inner wall of the accommodating cavity. The through holes connect the accommodating cavity and the outside of the top cover only through the waterproof and breathable membrane layer.
[0010] As a preferred embodiment of this utility model, the multiple sets of separating components are evenly distributed from left to right within the accommodating cavity.
[0011] As a preferred technical solution of this utility model, the partition component includes a fixed plate fixed to the top of the bottom cover and multiple sets of uprights fixed to the top of the fixed plate, with the multiple sets of uprights evenly distributed on the top of the fixed plate.
[0012] As a preferred embodiment of this utility model, the accommodating cavity is sealed by the bottom cover and the top cover being glued together.
[0013] As a preferred embodiment of this utility model, the through holes are provided in multiple sets.
[0014] As a preferred technical solution of this utility model, the waterproof and breathable membrane layer is an expanded polytetrafluoroethylene membrane layer.
[0015] The beneficial effects of this utility model are as follows:
[0016] By setting multiple sets of partition components in the accommodating cavity, the accommodating cavity is divided into multiple compartments. Each compartment is used to place bread slices. The partition components prevent the bread slices in the compartments from touching each other and sticking, making them easy to take out.
[0017] Meanwhile, the cavity is designed as a sealed space, with through holes on the top cover, and a waterproof and breathable membrane layer is attached and fixed to the inner wall of the cavity. The through holes connect the cavity and the outside of the top cover only through the waterproof and breathable membrane layer, so as to allow for ventilation and moisture removal, expelling excess moisture and maintaining the taste of food.

[0019] Figure 2 yes Figure 1 A schematic diagram of the right-side partial structure.
[0020] Reference numerals: Bottom cover-1, Top cover-2, Separator assembly-3, Through hole-4, Waterproof and breathable membrane layer-5, Fixing plate-31, Upright pole-32. Detailed Implementation Example 1:
[0021] like Figures 1-2 As shown, this embodiment proposes a packaging box for sliced bread, including a bottom cover 1 and an upper cover 2 that is attached and fixed thereon. An accommodating cavity is formed between the bottom cover 1 and the upper cover 2. The bottom end of the upper cover 2 is attached to the outer periphery of the top of the bottom cover 1 to fix it in place (the fixing position can be achieved by adhesive or other methods).
[0022] The accommodating cavity is provided with multiple sets of partition components 3, which are fixed to the bottom cover 1 respectively. The multiple sets of partition components 3 divide the accommodating cavity into multiple compartments for storing sliced bread. The sliced bread in the multiple compartments do not come into contact with each other. That is, multiple sets of partition components 3 are set in the accommodating cavity. The distribution of the multiple sets of partition components 3 divides the accommodating cavity into multiple compartments. Each compartment is used to hold bread slices. The partition components 3 separate and block the sliced bread in the compartments so that they do not come into contact and stick together, making them easy to take out.
[0023] Among them, multiple sets of partition components 3 are evenly distributed from left to right within the accommodating cavity (e.g. Figure 1 As shown, the dividing components 3 are vertically plate-shaped and evenly distributed from left to right at the top of the bottom cover 1. Each adjacent dividing component 3, as well as the first and last groups, form a separate compartment with the inner wall of the top cover 2. Slices of bread are placed in each compartment.
[0024] To implement the above-mentioned partition component 3, a specific structure and composition of the partition component 3 are proposed, which can be as follows: The partition component 3 includes a fixed plate 31 fixed to the top of the bottom cover 1, and multiple sets of uprights 32 fixed to the top of the fixed plate 31. The multiple sets of uprights 32 are evenly distributed on the top of the fixed plate 31 (e.g., Figure 2 As shown, two sets of uprights 32 are fixed to the top of the fixed plate 31. The two sets of uprights 32 are preferably symmetrically arranged at the top of the fixed plate 31 to ensure the maximum support position for the sliced bread. The fixed plate 31 and the uprights 32 prevent adjacent sliced bread from contacting each other. The uprights 32 and the fixed plate 31 do not completely cover the bread slices, so the bread slices can be easily taken out and eaten from the uncovered parts. Example 2:
[0025] like Figure 1 As shown, the difference between it and embodiment 1 is that it also includes several sets of through holes 4 provided on the upper cover 2 and waterproof and breathable membrane layer 5 attached and fixed to the inner wall of the accommodating cavity. Through holes 4 are respectively provided at the left and right ends of the upper cover 2 to connect the inner and outer sides of the upper cover 2, and two sets of waterproof and breathable membrane layers 5 are symmetrically provided at the left and right ends of the inner wall of the upper cover 2.
[0026] The through hole 4 connects the accommodating cavity and the outside of the top cover 2 only through the waterproof and breathable membrane layer 5. That is, when the through hole 4 is ventilated, it must pass through the waterproof and breathable membrane layer 5.
[0027] The accommodating cavity is sealed by the bottom cover 1 and the top cover 2 is glued to it. The bottom end of the top cover 2 is glued to the outer periphery of the top of the bottom cover 1, and double-sided adhesive tape or the like can be used for gluing and fixing.
[0028] Multiple sets of through holes 4 are provided to improve air permeability;
[0029] The waterproof and breathable membrane layer 5 is an expanded polytetrafluoroethylene membrane layer, etc. [Expanded polytetrafluoroethylene membrane, also often called ePTFE membrane, is a porous material made of polytetrafluoroethylene (PTFE) resin through a special process], which is used to efficiently expel water vapor from the bag body 1, reduce internal humidity, prevent the diaper body 4 from getting damp, and at the same time maintain the airtightness and hygiene of the packaging.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
