Description

Technical Field

[0001] The utility model relates to the technical field of food containers. Background Art

[0002] Food containers can be used to store, preserve, freeze or heat food, such as supplementary food boxes, lunch boxes, fresh-keeping boxes, etc. The food container includes a container body with a cavity, an opening connected to the cavity is opened on the top surface of the container body, and a lid is provided at the front end of the container body to cover the opening. In order to fix the lid on the container body, the prior art provides mutually cooperating lid fixing structures on the container body and the lid; in addition, in order to prevent the food in the container body from overflowing, the prior art provides mutually cooperating container sealing structures on the container body and the lid. Since the container body and the lid each need to be provided with two structures, namely, a lid fixing structure and a container sealing structure, the structure is complicated. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a food container, wherein the container body and the lid only need to be provided with a structure that cooperates with each other, so as to realize the two functions of fixing the lid and sealing, and the structure is simple.

[0004] In order to solve the above technical problems, the utility model provides a food container, which includes a container body with a cavity, an opening leading to the cavity is formed on the top surface of the container body, the opening is covered with an elastically deformable lid, an insertion portion extending downward into the cavity is formed on the bottom surface of the lid, the insertion portion is provided with a lid clamping portion protruding radially outward, the upper surface of the lid clamping portion is provided with a lid clamping section, the radial end of the lid clamping section is not lower than the radial start end, the side wall of the container body is correspondingly provided with a side wall clamping portion protruding radially inward, the lower surface of the side wall clamping portion is provided with a side wall The wall clamping section, the radial end of the side wall clamping section is not higher than the radial starting end, the lid moves downward so that the cover clamping portion is squeezed inward by the side wall clamping portion and then passes downward over the side wall clamping portion and then rebounds outward until the cover clamping section provided by the utility model is hidden under the side wall clamping section provided by the utility model to achieve clamping, in the clamped state, the clamping portion of one of the lid and the side wall of the container body is tightly against the other to achieve sealing; the lid is deformed by operation so that the radial end of the cover clamping section is offset inward until it is no longer hidden under the side wall clamping portion, and the lid can be moved up to open.

[0005] Furthermore, the side wall snap-in section and / or the cover snap-in section are horizontal.

[0006] Furthermore, the upper surface of the side wall clamping portion is formed into a guiding slope and / or the lower surface of the cover clamping portion is formed into a guiding slope to guide the extending portion of the cover to deviate inwardly and extend into the cavity.

[0007] Furthermore, the container body can be elastically deformed to cause the top of its side wall to shift outward, the top of the extension part of the lid protrudes radially outward, and an outer buckle part extends downward from the outer peripheral side of the lid; in the above-mentioned engaging state, the top of the extension part and the outer buckle part radially clamp the side wall of the container body.

[0008] Furthermore, a groove is formed between the cover clamping portion and the top of the extending portion, the upper surface of the cover clamping portion is the lower groove wall of the groove, and the bottom end of the outer buckle portion is higher than the upper surface of the cover clamping portion.

[0009] Furthermore, in the above-mentioned engaging state, the side wall engaging portion is tightly attached to the cover engaging portion to realize the sealing provided by the utility model.

[0010] Furthermore, the extending portion is wider than the cavity, and the cover clamping portion is pushed inward by the side wall clamping portion, which is specifically achieved by elastically contracting the extending portion inward.

[0011] In this food container, when the lid is moved down, the cover engaging portion is pushed inward by the side wall engaging portion, then moves downward over the side wall engaging portion and then rebounds outward until the cover engaging section is hidden under the side wall engaging section to achieve engagement. In the engaged state, if the lid attempts to move up and open directly, since the cover engaging section is hidden under the side wall engaging section, the cover engaging section will be blocked by the side wall engaging section, and the lid will not move up and open directly; since the radial end of the side wall engaging section is not higher than the radial beginning and the radial end of the cover engaging section is not lower than the radial beginning, the force (axial force) of the lid attempting to move up cannot be converted into an inward force (radial force), and the cover engaging portion will not be pushed inward and thus cannot move upward over the side wall engaging section, ensuring that the lid cannot move up and open directly, and the lid can be securely fixed on the container body. If the lid needs to be opened, the lid is operated to be offset and deformed inward to pass over the side wall engaging section, and the lid can be moved up and opened. In the engaged state, the clamping portion of one of the lid and the side wall of the container body is in close contact with the other, and the container body can be sealed without providing a sealing structure other than the clamping portion. In this way, the container body and the lid only need to have a clamping portion that cooperates with each other, and this simple structure can achieve the two functions of fixing the lid and sealing.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with specific implementation methods.

[0022] Take the food container as an example, see Figure 1 The food supplement box comprises a container body 1. Figure 4 The container body 1 has a cavity 12, and an opening 13 leading to the cavity 12 is formed on the top surface of the container body 1. The side wall 14 of the container body 1 is provided with a side wall clamping portion 11 radially protruding inward. The side wall clamping portion 11 is annular and surrounds the central axis of the container body 1. The side wall clamping portion 11 and the container body 1 are integrally formed, and are both made of food-grade silicone material and can be elastically deformed. Figure 4 The longitudinal section at B is shown in Figure 7 The upper surface 51 of the side wall clamping part 11 is made into a guiding slope, the starting end of which is connected to the side wall 14 of the container body 1 and the end of which is connected to the side surface 52 of the side wall clamping part 11; the lower surface 53 of the side wall clamping part 11 is mainly a horizontal side wall clamping section 50, the radial end 502 of the side wall clamping section 50 is at the same height as the radial starting end 501, the lower surface 53 of the side wall clamping part 11 is connected to the side wall 14 of the container body 1 at the starting end and connected to the side surface 52 of the side wall clamping part 11 at the end. The connection between the surfaces of the side wall clamping part 11 is made into a rounded corner. Figure 1 The food supplement box also includes a lid 2. Figure 5The bottom surface of the cover 2 is provided with a protruding portion 23 facing downwards. The protruding portion 23 is annular and surrounds the central axis of the container body 1. The inner diameter of the protruding portion 23 is larger than the inner diameter of the cavity 12, that is, the protruding portion 23 is wider than the cavity 12. The bottom of the protruding portion 23 is provided with a cover clamping portion 231 protruding radially outward. The cover clamping portion 231 is annular and surrounds the central axis of the container body 1. Figure 8 The main body of the upper surface 61 of the cover clamping part 231 is a horizontal cover clamping section 60, the radial end 602 of the cover clamping section 60 is at the same height as the radial start 601, and the lower surface 62 of the cover clamping part 231 is formed into a guiding slope. The ends of the upper surface 61 and the lower surface 62 of the cover clamping part 231 are connected, and the start ends are respectively connected to the extension part 23. The connection between the surfaces of the cover clamping part 231 is made into a rounded corner. Figure 5 The outer circumference of the cover 2 extends downwardly with an outer buckle portion 21, which is annular and surrounds the central axis of the container body 1. Figure 8 The top 232 of the extension portion 23 radially protrudes outward, and a groove 4 is formed between the top 232 of the extension portion 23 and the cover clamping portion 231. The lower groove wall of the groove 4 is the upper surface 61 of the cover clamping portion 231. The bottom end of the outer buckle portion 21 is higher than the upper surface 61 of the cover clamping portion 231. Figure 6 As shown, in this way, the groove 4 is not blocked by the outer buckle part 21, which is convenient for cleaning. The protruding part 23, the cover clamping part 231, the outer buckle part 21, the cover 2, etc. are all made of food-grade silicone material and can be elastically deformed. If the cover 2 needs to be covered on the container body 1, align the protruding part 23 of the cover 2 with the opening 13 of the container body 1, and then press the cover 2 downward to make the protruding part 23 extend into the cavity 12. The cover clamping part 231 will elastically shrink and deform downward and inward along the guiding slope of the side wall clamping part 11 through its own guiding slope, that is, it will be squeezed inward by the side wall clamping part 11, and then pass over the side wall clamping part 11 downward, and then rebound to the outside until its cover clamping section 60 is hidden under the side wall clamping section 50 to achieve clamping, as shown in FIG. Figure 6 As shown, the lid 2 is fixed on the container body 1. In this engaged state, the top of the container body 1 extends between the lid clamping portion 231 and the top 232 of the extension portion 23, so that the lid clamping portion 231 is on the outside and the top 232 of the extension portion 23 is on the inside, radially clamping the top of the container body 1 together to prevent the top of the container body 1 from deviating and deforming outward and causing the lid 2 to fall out, ensuring that the lid 2 is firmly fixed on the container body 1. The side wall clamping portion 11 is tightly against the lid clamping portion 231 to achieve a leak-proof seal on the container body 1 to prevent the liquid in the cavity 12 from leaking out. Figure 2 , 3 The top surface of the cover 2 is provided with an exhaust hole 24 leading to the chamber 12, and a plug 3 is plugged in the exhaust hole 24. Figure 1The lid 2 is provided with a buckle cover 22, which is also made of food-grade silicone material, can be elastically deformed, and is integrally formed with the extension portion 23, the cover clamping portion 231, the outer buckle portion 21, and the lid 2; if the lid 2 needs to be opened, the buckle cover 22 is buckled outward to cause the lid 2 to deflect inward until the cover clamping portion 231 is no longer hidden under the side wall clamping portion 11, and the lid 2 can be opened.

[0023] In this embodiment, the side wall clamping section 50 and the cover clamping section 60 are horizontal; in other embodiments, the side wall clamping section 50 can be changed into a non-horizontal section (not shown) with a radial end lower than the radial beginning, as long as its radial end is not higher than the radial beginning, and the cover clamping section 60 can be changed into a non-horizontal section (not shown) with a radial end higher than the radial beginning, as long as its radial end is not lower than the radial beginning.

[0024] In order to achieve leak-proof sealing, in the present embodiment, the side wall clamping portion 11 is in close contact with the cover clamping portion 231; in other embodiments, to achieve leak-proof sealing, the side wall clamping portion 11 may be changed to be in close contact with a portion other than the cover clamping portion 231 on the extension portion 23, or the cover clamping portion 231 may be changed to be in close contact with a portion other than the side wall clamping portion 11 on the side wall 14 of the container body 1 (not shown).

[0025] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
