Description

Technical Field

[0001] This utility model relates to the field of food storage container technology, and in particular to a food container. Background Technology

[0002] In daily life, food containers are used for storing, steaming, and cooking food. In existing technologies, such as the baby food cup disclosed in patent number CN207524302U, the lid structure includes components such as a silicone plug, annular protrusion, and sealing ring. Although it achieves negative pressure preservation through a vacuum structure, the multi-layered nested structure of the first recess, second recess, and through hole in the middle of the lid makes it easy for food residue to remain during cleaning, and the gap between the silicone plug and the through hole is difficult to clean thoroughly. Another example is the food preservation box disclosed in patent number CN208842904U, which adopts an inner box and outer box design. The inner box is made of soft silicone, and the lid is sealed to the inner box through a lid fitting part. However, the annular groove formed by the arc-shaped flange of the lid fitting part and the edge of the inner box, as well as the fitting gap between the outer box fitting part and the lid, are prone to accumulating stains during long-term use. Although the silicone inner box is easy to demold, the lid structure lacks a visual design. When steaming or cooking, the lid must be opened to observe the state of the food, which affects the convenience of operation and may lead to heat loss.

[0003] Existing food container lid structures have shortcomings in terms of ease of cleaning, steaming, and observation. For example, ordinary lids often use multi-layered concave-convex or nested structures, and the complex construction leads to many cleaning dead spots. The lack of visual design makes it difficult to intuitively present the food's state during steaming or cooking. Furthermore, some sealing structures increase component complexity in pursuit of airtightness, further exacerbating the difficulty of cleaning and affecting the user experience. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a food container.

[0005] This utility model proposes a food container, which includes a container body and a silicone inner cover. The inner cover is detachably and sealed to the container body. The inner cover has a planar structure in the middle and several air holes. The silicone thickness of the inner cover planar structure is 0.3-0.6mm.

[0006] In the above technical solution, the detachable and sealed design of the silicone inner lid and the container body enables repeated use and convenient cleaning; the thin silicone design of the inner lid's flat structure, combined with the air holes, causes the inner lid's flat surface to bulge due to temperature and air pressure changes during steaming, visually displaying the food's state, while the air holes balance the internal and external air pressure, preventing the container from deforming.

[0007] Furthermore, the diameter of the pores is 0.2-0.5mm. This size range of pores ensures the slow release of gas during steaming, preventing sudden steam bursts that could cause scalding, and also effectively prevents food particles from spilling out, keeping the outside of the container clean.

[0008] Furthermore, the inner lid also includes an inner lid latching part disposed on the periphery of the inner lid planar structure. The silicone thickness d1 of the inner lid planar structure and the silicone thickness d2 of the inner lid latching part satisfy the thickness relationship d1 < d2. Through differentiated thickness design, the inner lid planar structure is more easily heated and protrudes during steaming or cooking, enhancing the intuitiveness of observing the food's state; at the same time, it maintains the structural strength of the inner lid latching part, ensuring a stable connection with the container body.

[0009] Furthermore, the open edge of the container body extends outward to form a fixing part, which is detachably and sealingly connected to the inner cover snap-fit ​​part. The detachable sealing design of the fixing part and the inner cover snap-fit ​​part facilitates the installation and removal of the inner cover, ensuring sealing reliability, simplifying the cleaning process, and avoiding the cleaning dead spots problem of traditional fixed structures.

[0010] Furthermore, the lower surface of the inner lid's snap-fit ​​part is provided with a raised strip and a groove, while the upper surface of the fixing part is provided with a boss that matches the groove. The raised strip snaps into the side wall of the container body. Through the dual mechanical cooperation of "raised strip-side wall snap-fit" and "groove-boob fitting", a stable connection between the inner lid and the container body is achieved, improving the sealing performance. This structure utilizes the elastic deformation of silicone to achieve convenient disassembly and assembly, while avoiding stain residue caused by complex structures.

[0011] Furthermore, the inner lid has a planar circular structure that is recessed into the container body cavity. The recessed planar circular structure matches the circular opening of the container body, ensuring uniform force distribution and improving the sealing effect. The recessed design makes the inner lid plane more likely to bulge due to pressure difference during steaming, enhancing the visibility effect. At the same time, the circular structure facilitates mold processing and reduces production costs.

[0012] Furthermore, the container body is made of either PPSU or glass. PPSU is characterized by its high temperature resistance, impact resistance, and non-toxicity, making it suitable for high-temperature cooking and resistant to aging. Glass is transparent, easy to clean, and does not release harmful substances. Both materials meet food safety requirements and are suitable for different usage scenarios.

[0013] Furthermore, the food container also includes an outer lid, which comprises an integrally molded outer lid snap-fit ​​part and an outer lid planar structure. The outer lid planar structure is adapted to the inner lid planar structure, and the outer lid snap-fit ​​part is detachably and sealingly connected to the container body. The outer lid and inner lid form a double-layer protective structure, further enhancing sealing and dustproof capabilities, making it suitable for long-term storage or carrying when traveling. The detachable design facilitates the cleaning and replacement of the outer lid, improving ease of use.

[0014] Furthermore, the outer cover latching part has a recessed groove extending inward from the periphery of the outer cover, and the lower surface of the fixing part has a protrusion that matches the groove. The cooperation between the groove and the protrusion provides a reliable mechanical lock, ensuring that the outer cover is not easily dislodged when subjected to external impact. At the same time, this structural design allows users to open it with one hand, improving ease of use.

[0015] Furthermore, the outer periphery of the fixing part is recessed inward to form a groove structure. The groove structure provides a point of leverage for the user's fingers, making it easier to apply leverage when removing the inner cover and reducing the difficulty of opening.

[0016] Furthermore, the container body has a circular horizontal cross-section. The circular opening design ensures a uniform contact area between the inner lid and the container body, improving sealing performance; at the same time, it eliminates blind spots during cleaning, facilitating thorough cleaning and meeting food safety standards.

[0017] Compared with the prior art, the beneficial results of this utility model are as follows:

[0018] 1. The thin silicone of the inner cover with the concave design makes it bulge during steaming due to the pressure difference, allowing users to judge the doneness of the food by its deformation; 0.2-0.5mm air holes balance the air pressure, prevent steam splashing, and ensure uniform heat conduction.

[0019] 2. The inner cover of this utility model achieves detachable sealing through "protrusion strip-side wall snap-fit ​​+ groove-protrusion fitting", which, together with the outer cover's slot-protrusion fastening, constructs a double sealing system; the silicone material is easy to clean, and the groove structure of the fixing part assists in disassembly, solving the problem of cleaning dead corners of traditional covers.

[0020] 3. The container body of this utility model supports dual material options: PPSU (high temperature resistant, impact resistant) and glass (high transparency, easy to clean). The inner lid is made of silicone for food contact safety, and the outer lid has a snap-fit ​​structure for enhanced protection. From daily household steaming and microwaving to portable storage and long-term preservation when traveling, it solves the problem of poor adaptability of traditional containers, significantly improving product practicality and user lifecycle value.

Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0030] This utility model proposes a food container, referencing... Figures 1-2 as well as Figures 3a-3c , Figure 1 and Figure 2 Perspective views of a food container according to an embodiment of the present invention and a food container without an outer lid are shown respectively. Figures 3a-3cThe figures show a front view, a cross-sectional view along direction AA, and a partial enlarged view at point e, all of which are shown in the figures. As shown, the food container includes a container body 100 and a lid. The lid consists of an inner lid 200 and an outer lid 300. The inner lid 200 is made of silicone and has an integrally formed inner lid engaging portion 201 and an inner lid planar structure 202 recessed into the cavity of the container body 100. The inner lid planar structure 202 has several air holes 2021. The lower surface of the inner lid engaging portion 201 has a protrusion 2012 and a groove 2011. The open edge of the container body 100 extends outward to form a fixing portion 102. The upper surface of the fixing portion 102 has a boss 1021 adapted to the groove 2011. The protrusion 2012 engages with the side wall 101 of the container body 100, thereby achieving the connection and fixation between the inner lid 200 and the container body 100, constructing a food container structure with specific sealing characteristics.

[0031] In some specific embodiments, reference is made to Figures 3a-3c and Figures 4a-4b , Figures 4a-4b The figures show a front view and a cross-sectional view along the BB direction of an outer cover body according to an embodiment of the present invention. As shown, the outer cover body 300 is composed of an integrally formed outer cover snap-fit ​​part 301 and an outer cover planar structure 302. The outer cover planar structure 302 is adapted to the inner cover planar structure 202, and the outer cover snap-fit ​​part 301 is connected to the fixing part 102 by a snap-fit ​​method. Specifically, the outer cover snap-fit ​​part 301 is provided with a groove 3011 recessed inward along the periphery of the outer cover body 300, and the lower surface of the fixing part 102 is provided with a protrusion 1022 that matches the groove 3011. By means of the cooperation between the groove 3011 and the protrusion 1022, the outer cover body 300 and the container body 100 are snapped together, and the inner cover body 200 is snapped between the outer cover body 300 and the container body 100, which enhances the overall sealing and protection, and at the same time forms a dustproof protection for the inner cover body 200, ensuring the integrity of the inner cover body structure and the functional stability. In some specific embodiments, refer to Figures 3a-3c and Figures 5a-5c , Figures 5a-5c The figures show a front view, a cross-sectional view along the CC direction, and a partial enlarged view at point f of the inner lid body according to an embodiment of the present invention. As shown, the inner lid body 200 is made of silicone material and consists of an integrally formed inner lid snap-fit ​​part 201 and an inner lid planar structure 202 recessed into the cavity of the container body 100. The inner lid planar structure 202 is preferably a planar circular structure. Utilizing the properties of silicone material, it can bulge and deform due to changes in internal air pressure during steaming or cooking. The deformation state can be observed to help confirm the steaming or cooking process of the food. Its surface is distributed with several air holes 2021, the diameter of which is controlled between 0.2-0.5 mm, to balance the air pressure inside and outside the container and ensure the gas exchange requirements during steaming, cooking, and storage.

[0032] Preferably, the silicone thickness d1 of the inner lid planar structure 202 and the silicone thickness d2 of the inner lid snap-fit ​​part 201 satisfy the thickness matching relationship of d1 < d2; wherein, the silicone thickness d1 of the inner lid planar structure 202 is preferably 0.3-0.6mm, adopting a thin silicone design, which can quickly respond to heat conduction and bulge deformation during steaming and cooking, providing users with a direct basis for judging the doneness of food. The lower surface of the inner lid snap-fit ​​part 201 is provided with a protrusion 2012 and a groove 2011, and the upper surface of the container body 100 fixing part 102 is correspondingly formed with a boss 1021 that matches the groove 2011. The protrusion 2012 snaps into the side wall 101 of the container body. Through the dual mechanical cooperation of "protrusion-side wall snap-fit ​​+ groove-boob fitting", the inner lid 200 and the container body 100 are detachably fixed.

[0033] In some specific embodiments, reference is made to Figures 3a-3c and Figures 6a-6c , Figures 6a-6c The figures show a front view, a cross-sectional view along the DD direction, and a partial enlarged view at point g, all according to an embodiment of the present invention. As shown, the container body 100 serves as the main structure for containing food, with its open edge extending outward to form a fixing part 102. Two inwardly recessed slot structures 1023 are symmetrically arranged on the outer periphery of the fixing part 102. These slot structures provide a point of leverage for the user, facilitating the separation and disassembly of the inner lid 200 from the container body 100 using tools or hand force, thus improving ease of use. The horizontal cross-section of the container body 100 is preferably circular, and the material can be polyphenylsulfone (PPSU) or glass, meeting the requirements for food contact safety and structural stability. In the fitting connection with the inner lid 200, the protrusion 1021 of the fixing part 102 is made of a hard material, while the groove 2011 of the inner lid snap-fit ​​part 202 is adapted to the soft properties of silicone, utilizing the elastic deformation of the silicone to achieve quick assembly and disassembly. This differentiated design of "hard-soft" materials not only meets the stability requirements of the connection between the inner lid 200 and the container body 100 through the mechanical cooperation of rigid bosses and elastic grooves, but also achieves a rapid cleaning effect on the inner lid and the inside of the container by taking advantage of the easy-to-clean and dead-angle-free properties of silicone material, thereby improving the convenience of product use and the efficiency of hygiene maintenance.
