Description

Technical Field

[0001] This utility model relates to the field of food processing and storage technology, and in particular to a multi-purpose food preservation box. Background Technology

[0002] Traditional bread slicers suffer from structural sealing defects, making the sliced ​​bread susceptible to moisture and spoilage. Their fixed, bulky design also severely restricts portability. While existing fruit preservation boxes achieve basic preservation functions through design, they generally lack integration with food processing tools, making it difficult to meet the needs of multiple usage scenarios. This single-function product design model forces users to carry multiple separate devices in outdoor scenarios such as camping, resulting in low utilization of storage space.

[0003] While the cutting device disclosed in US Patent 9,636,831 solves the problem of food cutting, its independent structural design is completely separate from its preservation function. It neither achieves integrated integration with the preservation container nor optimizes the compactness for outdoor carrying. Although existing products on the market have partially improved portability, they still require additional cutting tools, leading to the core pain points of users facing fragmented functional modules and cumbersome operation procedures. More importantly, the current cutting devices with simple assembly and disassembly characteristics are not structurally designed to effectively complement the functions of the preservation container, nor can they meet the stringent requirements of lightweight and compact products in outdoor scenarios.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0048] like Figures 1 to 5 As shown, this utility model provides a multi-purpose food storage box, including a box body 1, a slicing accessory 2, and a food storage accessory 3. The box body 1 has a storage chamber 11 and at least one opening 12. The box body 1 is provided with a support flange 13 for supporting the various accessories. The slicing accessory 2 can guide and cut bread into slices with the aid of a knife in the use state, and has a use state and a storage state. The food storage accessory 3 includes a mounting frame 31 detachably mounted on the support flange 13 and at least one receiving frame 32. The receiving frame 32 can be used to place and store fruit, and it is connected to the mounting frame 31 by a hanging method.

[0049] like Figure 6 As shown, the slicing accessory 2 can be detachably placed on the support flange 13 or the mounting frame 31 in the use state to form a stable operating platform; as Figure 2 As shown, when the slicing accessory 2 is folded or disassembled, it is stored in the storage chamber 11 of the box body 1 in a stowed state; the receiving frame 32 can also be disassembled and stored in the storage chamber 11 of the box body 1 when not in use, so as to save space and maintain the overall aesthetics.

[0050] like Figures 6 to 11 As shown, in this embodiment, the slicing accessory 2 includes a base plate 21, side plates 22, and a positioning partition 23. The base plate 21 has a flat support surface 211 and a storage groove 212 on its back. Side plates 22 are symmetrically installed on both sides of the support surface 211. The two side plates 22 are spaced apart from each other at a predetermined distance to serve as guide sidewalls and are arranged in parallel. At least one side plate 22 is provided with multiple tool guide grooves 221 for guiding the movement of the tool to perform cutting work. The positioning partition 23 is detachably installed between the two side plates 22 and forms a stable baffle when the slicing accessory 2 is in use. The bread can be placed on the baffle to help fix the object to be cut.

[0051] like Figures 6 to 11 As shown, when the slicing accessory 2 is in use, the base plate 21 is mounted on the support flange 13 or the mounting frame 31 with the support surface 211 facing upwards to provide support, such as... Figure 2 As shown, when the slice accessory 2 is in the storage state, the base plate 21 is installed on the support flange 13 or the mounting frame 31 with the storage groove 212 facing upwards, and the positioning partition 23 and the side plate 22 are both stored in the storage groove 212.

[0052] like Figures 6 to 10 As shown, to further address the differences in slice thickness preferences among different users, this embodiment arranges the tool guide slots 221 on the side plate 22 at unequal intervals. These unequal intervals allow for various thicknesses in the side plate 22 portion between adjacent tool guide slots 221, providing a range of cutting thickness options. The aforementioned unequal intervals can be random or gradually increasing. In some embodiments (not shown), scales and numerical markings are engraved on the outer side of the side plate 22, with each tool guide slot 221 corresponding to a unique mark, facilitating intuitive selection and recording of commonly used thicknesses by the user.

[0053] like Figure 8 As shown, in the past, due to insufficient blade sharpness, bread slices often stuck together on the bottom or sides, requiring manual separation by the user. In this embodiment, several cutting grooves 213 are formed on the support surface 211 of the base plate 21 to cooperate with the blade guide groove 221. The cutting grooves 213 are aligned with the blade guide groove 221. The width of the cutting grooves 213 is just enough to accommodate the blade tip, and it has sufficient depth so that the blade can cut deeper during cutting, completely separating the bread slices and preventing uncut stuck parts from remaining on the bottom or sides.

[0054] like Figures 8 to 11 As shown, the cutting groove 213 is aligned with the tool guide groove 221. This can be understood as follows: the side plate 22 is set along the length direction of the base plate 21, and the tool moves along the width direction of the base plate 21 to cut. Therefore, multiple cutting grooves 213 are arranged on the base plate 21 along the length direction. Each cutting groove 213 extends continuously or intermittently in the width direction. The arrangement of the multiple cutting grooves 213 in the length direction corresponds one-to-one with the tool guide groove 221 on the side plate 22.

[0055] The upper edge of the side plate 22 adopts a curved surface design including concave or wavy shapes to form a progressive guide slope. The curved surface contour forms a good anti-slip engagement with the tool / positioning partition 23. The lowest point of the curved surface forms a drainage angle with the inlet of the tool guide groove 221 to ensure the self-alignment effect when the instrument is inserted.

[0056] like Figures 5 to 11As shown, in response to the problem of bread crumbs generated during the bread slicing process, especially given that this product is also designed for outdoor environments, the base plate 21 has several crumb drainage holes 214. The crumb drainage holes 214 extend through the upper and lower parts of the base plate 21, and the diameter of the holes is sufficient to allow the bread crumbs generated during the slicing process to fall smoothly. The shape and arrangement of the crumb drainage holes 214 can be selected in various ways. In this embodiment, the crumb drainage holes 214 adopt a long strip shape that is parallel to the side plate 22.

[0057] In addition to slicing bread, this product can also be used to cut meat and other ingredients. Through the coordinated design of the chip discharge hole and the cutting groove 213, the bread crumbs and meat blood and other by-products generated during the cutting process are directed to the chip collection area, realizing the effective collection and separation of processing residues. The trapezoidal cross-section design of the cutting groove 213 can prevent chip accumulation and blockage. All contact surfaces are made of food-grade materials to ensure hygiene and safety.

[0058] In some embodiments (not shown), a removable crumb tray is configured below the base plate 21 to collect fallen bread crumbs; the crumb tray can be quickly removed for easy cleaning and carrying; or it can be collected directly through the storage chamber 11 or the receiving frame 32 of the box body 1. Figures 12 to 14 As shown, there are several receiving frames, which are suspended on the mounting frame to form independent compartments. The interior of each receiving frame can also be divided into compartments by setting positioning partitions. When the receiving frames are suspended on the mounting frame, a gap is maintained between the bottom of the receiving frame and the bottom of the box storage chamber, which is equivalent to dividing the box storage chamber to form a placement cavity. A replaceable cold / warm insulation module, such as ice cubes or heating elements, is set at the bottom of the mounting frame of the preservation accessories. The module has a built-in phase change material, which can extend the preservation time of fruits or vegetables in the box by pre-cooling or heating. The module is connected to the mounting frame by a snap or magnetic structure for easy disassembly and cleaning. Alternatively, when not in use, the side panels and positioning partitions of the slicing accessories can be stored in the placement cavity.

[0059] The box body 1 can be equipped with a pull-out condensate collection drawer on its side wall or bottom. The drawer is conveniently accessed and placed through a side or bottom embedded slide rail structure. It is used to collect condensate, melted ice liquid, food residue or blood generated during the preservation or slicing process. The inner surface of the drawer is treated with a hydrophobic and easy-to-clean coating. Combined with the directional flow design of the guide channel, it ensures that liquid and debris are efficiently collected in the collection area. It can also be quickly disassembled and cleaned to ensure the long-term hygiene and cleanliness of the device.

[0060] like Figure 13As shown, at least one receiving frame 32 has a through hole 321 at its bottom, connecting the upper and lower parts of the receiving frame 32; at least one receiving frame 32 has a slotted hole 322 on its side wall, connecting the inner and outer spaces of the receiving frame 32; the total opening area of ​​the through hole 321 and the slotted hole 322 accounts for more than 20% of the surface area of ​​the receiving frame 32 to improve ventilation efficiency; or, in a further design, bread crumbs can also fall into the placement cavity through the through hole 321 and the slotted hole 322, and after the ice in the placement cavity melts, it can be used to simply rinse the bread crumbs in the storage chamber 11 of the box body 1. In some embodiments, the bottom through hole 321 adopts a honeycomb-shaped distribution structure, and the diameter and spacing of each small hole maximize ventilation efficiency while maintaining structural strength.

[0061] The bottom of the container 32 adopts a modular partition design, with a differentiated structure of a permeable zone and a sealed water-retaining zone. The permeable zone is equipped with an array of through holes 321 to meet the ventilation needs of fruits with high respiration rates, while the sealed water-retaining zone adopts a non-porous planar structure to meet the humidity retention requirements of fruits with low transpiration rates. The area ratio of the two types of zones can be flexibly adjusted according to the type of stored items, achieving targeted preservation while facilitating partition cleaning and maintenance.

[0062] Furthermore, for the implementation of the partitioned design, the receiving frame 32 is provided with a fixed or detachable insert plate, which can be used to divide the receiving frame 32 into different areas.

[0063] like Figures 3 to 5 As shown, in this embodiment, the support flange 13 is arranged circumferentially on the outer or inner wall of the box body 1; when the mounting frame 31 is installed on the support flange 13, the mounting frame 31 can also be used as part of the support flange 13; wherein, the forming method of the support flange 13 can be flexibly selected according to the material and process requirements, and it is mainly a protrusion limit formed on the box body 1, which provides reliable support for each accessory by extending intermittently or continuously along the circumferential direction of the box body 1.

[0064] In some embodiments (not shown in the figure), each of the holding frames 32 in the original box body 1 for storing fruits or ingredients is provided with a fixing accessory that cooperates with the box body 1. The fixing accessory is used to fix the holding frame 32 to the frame 31 or the frame 31 to the box body 1, so that the overall storage state is more stable and prevents shaking during carrying. The implementation method can be to achieve pre-tightening by using magnetic components or flexible components. Furthermore, the fixing accessory adopts a shape memory alloy flexible component, which automatically increases the pre-tightening force when encountering severe vibration, or tactile feedback protrusions are set on the surface of the flexible component to physically indicate the fixed status; or a retractable positioning pin is added to the bottom of the holding frame 32 to form a mechanical interlock with the pre-set guide hole of the frame 31.

[0065] For the material selection of the box body 1, this embodiment specifically uses a thermal insulation material with excellent thermal insulation properties. This material achieves bidirectional temperature regulation, effectively blocking external environmental temperature fluctuations while maintaining the ideal temperature state of the stored items for a long time, thereby significantly improving the food preservation time and quality maintenance effect. The thermodynamic properties of this thermal insulation material system can be further optimized through multi-layer composite processes or surface functionalization treatments. Implementation methods include: setting a vacuum insulation panel (VIP) sandwich structure in the box body 1 to significantly improve thermal insulation performance; applying aerogel composite materials to achieve thermal insulation effects with a thin thickness; developing antibacterial thermal insulation composite materials that combine temperature maintenance and antibacterial functions; and using color-changing temperature indicator materials to visually display the current thermal insulation status.

[0066] In some embodiments (not shown in the figures), the support flanges 13 can also be configured as two or more with different heights. The different lengths of the protrusions of the different support flanges 13 form different support surfaces, which are equivalent to shoulders with different outer diameters on the shaft, providing different positioning positions. For example, the base plate 21 and the mounting frame 31 can be mounted on two different support flanges 13. Multiple protrusions can also be provided on the support flanges 13, and mating grooves are opened at the bottom edge of the mounting frame 31 or the base plate 21 to prevent shaking under force after installation.

[0067] like Figures 1 to 2 As shown, the box body 1 is also equipped with a sealing cover 4. The top of the box body 1 is equipped with a handle 42 for easy carrying, and the bottom is equipped with a sealing ring 41. The bottom of the sealing cover 4 is equipped with a removable silicone sealing ring 41, which realizes the dual functions of airtightness and leakage prevention. The storage cavity is isolated from the outside world, which is both dustproof and fresh. It can be easily disassembled and replaced when cleaning. There is a gap between the bottom of the sealing cover 4 and the supporting flange 13, which divides the storage chamber 11 of the box body 1 to form a storage cavity. The storage cavity can accommodate the sliced ​​accessories 2 in the storage state.

[0068] like Figures 15 to 16 As shown, in one preferred storage method, the storage operation is performed according to the following steps: First, the individual components of the slicing accessory 2 are modularly disassembled, with the two side panels 22 placed parallel to each other at the bottom of the storage chamber 11 of the box body 1; then, the preservation accessory 3 is processed, and its receiving frame 32 can be stored in two ways—either placed directly on the upper surface of the side panel 22, or kept suspended in its original connected state on the mounting frame 31; next, the mounting frame 31 is snapped onto the supporting flange 13; then, the bottom plate 21 is placed over the upper part of the mounting frame 31 with the storage groove 212 facing upwards; finally, the positioning partition 13 is placed into or embedded in the storage groove 212, and the box cover 4 is fastened to complete the overall sealing. This storage solution achieves the orderly arrangement of multifunctional components within a limited volume through hierarchical space planning.

[0069] When bread needs to be sliced, firstly, assemble each independent component of the slicing accessory 2 according to the predetermined structure, and then selectively position and install the assembled slicing accessory 2 onto the support flange 13 of the box body 1; then, place the bread or other ingredients to be sliced ​​securely on the working surface of the base plate 21, and keep its end in contact with the positioning partition 13 to obtain stable support; finally, according to the actual cutting requirements, guide the cutting blade along the preset blade guide groove 221 on the side plate 22 to achieve precise slicing of bread or ingredients.

[0070] When fruit preservation is required, the mounting frame 31 of the preservation accessory 3 is first securely assembled onto the supporting flange 13 of the box body 1 using a precision snap-fit ​​structure. Then, based on the characteristics of the fruit variety and storage requirements, several holding frames 32 are selectively connected to the mounting frame 31 via a suspension mechanism, forming an adjustable connection. Next, the fruits to be preserved are placed in layers according to their type within each holding frame 32. A three-dimensional ventilation network composed of through holes 321 and slots 322 ensures optimal airflow spacing between the fruits. Finally, the box lid 4 is sealed to create an airtight space. Simultaneously, a replaceable cold-keeping module (such as a phase-change refrigerant or ice pack) is placed inside the box body 1 to achieve precise temperature control and preservation. This innovative solution, through the synergistic effect of a modular suspension structure and an intelligent ventilation system, not only achieves independent preservation of multiple fruit varieties but also significantly improves preservation time and quality maintenance.

[0071] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: different sizes of food storage boxes can be used to classify and store various foods such as fruits, vegetables, and cooked foods to avoid cross-contamination; through the design of the high-quality sealing ring 41, air can be effectively blocked from entering, slowing down the oxidation rate of food and thus extending the preservation time.

[0072] This technical solution's multi-functional food storage box improves the sealing performance of bread slices after slicing, preventing the bread from getting damp; enhances the product's portability, making it suitable for both indoor use and easy to carry when going out; and integrates a fruit preservation function, reducing the need for users to purchase multiple single-function products.

[0073] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0074] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
