airtight food storage container

Abstract

This utility model discloses a sealed food storage container, including a container body, a lid that fits with the container body, and a flexible sealing ring. The lid is a downward-opening cover structure. An annular groove with the opening facing downwards is provided around the outer edge of the container body's opening. The upper part of the sealing ring is embedded in the annular groove, while the lower part of the sealing ring protrudes outside the annular groove, sealing with the inner wall of the lid when the lid is placed on the container body's opening. This sealed food storage container achieves a seal while preventing the sealing ring from contacting the food inside the container, thus effectively preventing food stains from remaining on the sealing ring and preventing contamination of the food inside the container. Therefore, frequent disassembly and cleaning of the sealing ring is unnecessary, reducing the user's maintenance burden. Furthermore, since the edge of the lid and the sealing ring are not located within the internal space of the container body, the container body can achieve a larger effective volume with the same external dimensions, fully accommodating food and improving its internal space utilization.

Description

Technical Field

[0001] This utility model relates to the field of storage containers, specifically to a sealed food preservation box. Background Technology

[0002] To facilitate food transport and long-term storage, people typically use airtight food containers to prevent spoilage. Traditional open-top food containers use a silicone sealing ring at the bottom of the lid. When the lid is closed, the ring deforms and presses against the inner wall of the container, sealing the lid tightly against the opening and preventing airflow, thus achieving a good seal and extending shelf life. However, this design leaves the silicone sealing ring inside the container after sealing, taking up space and affecting the amount of food that can be stored. It also comes into direct contact with the food, making it easy for food residue to accumulate and form stains. Repeated use can lead to bacterial growth and food contamination. Therefore, the silicone sealing ring needs to be removed and cleaned after each use to ensure hygiene, adding extra work for the user. Utility Model Content

[0003] The purpose of this utility model is to overcome the problems existing in the above-mentioned background technology and provide a sealed food storage box with simple structure, good hygiene and high internal space utilization.

[0004] The sealed food storage box of this utility model includes a box body, a box lid that cooperates with the box body, and an elastic sealing ring. The box lid is a cover structure with a downward opening. The outer edge of the opening of the box body is surrounded by an annular groove with the opening facing downward. The upper part of the sealing ring is embedded in the annular groove, while the lower part of the sealing ring is exposed outside the annular groove. When the box lid is placed on the opening of the box body, it is sealed with the inner side wall of the box lid.

[0005] The airtight food storage container of this utility model has an annular groove around the outer edge of the opening of the container body, with the opening facing downwards. The sealing ring is correspondingly embedded in the annular groove, so that the sealing ring is outside the container body, does not occupy the space inside the container body, and does not directly contact the food inside the container. The lower part of the sealing ring is exposed outside the opening of the annular groove. When the lid is placed on the container body, the top surface of the lid abuts against the top of the annular groove on the container body, and the inner side wall of the lid will press against the exposed part of the sealing ring, causing the sealing ring to undergo elastic deformation and form a sealing contact with the inner side wall of the lid, thereby achieving the sealing effect of the food storage container. Therefore, the sealed food storage container with the above structure is simple in design, requiring no complex structure, which simplifies the production process and reduces manufacturing costs. During use, the sealing ring does not come into contact with the food inside, effectively preventing food stains from remaining on the sealing ring and preventing contamination of the food inside the container, ensuring good hygiene. This eliminates the need for frequent disassembly and cleaning of the sealing ring, reducing the user's maintenance burden. Furthermore, by designing the lid as a downward-opening cover structure, which cooperates with the sealing ring on the outside of the container, a seal is achieved while ensuring that the edge of the lid and the sealing ring are not within the internal space of the container. This allows the container to achieve a larger effective volume within the same external dimensions, maximizing food storage and improving the utilization of its internal space.

[0006] Preferably, the annular groove is integrally connected to the opening of the box body.

[0007] Preferably, the outer edge of the opening of the annular groove is provided with an inwardly protruding snap-fit ​​portion, and the outer side of the sealing ring is provided with a snap-fit ​​groove that matches the snap-fit ​​portion.

[0008] Preferably, the cross-section of the sealing ring is trapezoidal, narrower at the top and wider at the bottom.

[0009] Preferably, the lid is provided with a vent hole, and an elastic sealing plug that matches the vent hole is inserted into the vent hole.

[0010] Preferably, the box body is provided with anti-slip texture. Attached Figure Description

[0021] This utility model proposes a sealed food storage box.

[0022] like Figures 1 to 5As shown, the sealed food storage container described in this embodiment includes a container body 1, a lid 2 that mates with the container body 1, and a flexible sealing ring 3. The sealing ring 3 is made of silicone, which can be food-grade silicone, non-toxic, odorless, stable in performance, and adaptable to a wide temperature range. The lid 2 is a downward-opening cover structure. An annular groove 12 with its opening facing downwards is provided around the outer edge of the opening 11 of the container body 1. The upper part of the sealing ring 3 is embedded in the annular groove 12, while the lower part of the sealing ring 3 protrudes outside the annular groove 12, and seals against the inner wall of the lid 2 when the lid 2 is placed on the opening 11 of the container body. The above-described food storage container... Figure 5 As shown, the annular groove 12 on the outer edge of the opening 11 of the box body 1 surrounds the opening 11 and faces downwards, serving as a space for placing the sealing ring 3. The sealing ring 3 can be embedded in the annular groove 12, with its lower part exposed outside the opening of the annular groove 12. When the lid 2 is placed on the box body 1, the top surface of the lid 2 abuts against the top of the annular groove 12 on the box body 1, and the inner wall of the lid 2 will fit and press against the exposed part of the sealing ring 3, causing the sealing ring 3 to undergo elastic deformation and form a sealing contact with the inner wall of the lid 2, thus achieving the sealing effect of the food storage box. At this time, the sealing ring 3 can be placed outside the box space, therefore it will not... The lid 2 comes into direct contact with the food inside the box, thus effectively preventing food stains from remaining on the sealing ring 3 and preventing the food inside the box from being contaminated by the sealing ring 3, providing better hygiene. Therefore, the sealing ring 3 does not need to be frequently disassembled and cleaned, allowing for longer use and reducing the user's maintenance burden. Furthermore, by setting the lid 2 as a cover structure with the opening facing downwards, which cooperates with the sealing ring 3 outside the box body 1, a seal is achieved while the edge of the lid 2 and the sealing ring 3 do not occupy the storage space inside the box body 1. This allows the box body 1 to obtain a larger effective volume with the same external dimensions, so as to fully load food and improve its internal space utilization.

[0023] In some embodiments, the annular groove 12 and the opening 11 of the box body 1 may be integrally connected. Specifically, refer to... Figure 4 , Figure 5As shown, the annular groove 12 can be formed by bending the outer edge of the opening 11 of the box body 1 outward, so that the annular groove 12 and the box body 1 are integrally injection molded. Combined with the downward-facing cover structure of the lid 2, it can easily cover the box body 1. Using this structure, there is no need for a complex groove structure between the bottom of the box body 1 and the lid 2 for installation of the lid 2. Furthermore, the integral connection design between the annular groove 12 and the opening 11 of the box body simplifies the mold structure required during manufacturing, making the manufacturing process simpler, improving the production yield, and suitable for large-scale, low-cost manufacturing. The sealing ring 3 can be injection molded in the annular groove 12, resulting in better overall integrity, and the user does not need to remove the sealing ring 3 for cleaning. Of course, the sealing ring 3 can also be detachably embedded in the annular groove 12 for individual replacement and cleaning.

[0024] Specifically, such as Figure 5 The outer edge of the opening of the annular groove 12 is provided with an inwardly protruding snap-fit ​​portion 121, and the outer side of the sealing ring 3 is provided with a snap-fit ​​groove 31 that matches the snap-fit ​​portion 121. By fitting the snap-fit ​​portion 121 into the snap-fit ​​groove 31, the sealing ring 3 can be more securely installed in the annular groove 12, preventing it from falling off. The number of snap-fit ​​grooves 31 on the outer side of the sealing ring 3 can be one or more, to allow the sealing ring 3 to fit better into annular grooves 12 of different depths. Furthermore, the cross-sectional shape of the sealing ring 3 is set to be a trapezoid, narrower at the top and wider at the bottom, which allows the portion of the sealing ring 3 exposed outside the annular groove 12 to have a larger contact surface and volume. This facilitates the sealing fit between the sealing ring 3 and the inner wall of the lid 2, and makes it easier for the user to grasp the sealing ring 3 to insert it into or remove it from the annular groove 12.

[0025] In addition, to facilitate the venting of the food storage container, such as Figure 2 The box lid 2 is provided with a vent 21, and an elastic sealing plug 22 that mates with the vent 21 is inserted into the vent 21. The sealing plug 22 can be removed from the vent 21 when needed, thus allowing ventilation of the box interior and exterior without opening the box lid 2. The sealing plug 22 is made of silicone or rubber, facilitating insertion and removal from the vent 21. The sealing plug 22 can be configured to have an interference fit with the vent 21, ensuring a tighter seal and preventing air leakage during use. Furthermore, the box body 1 can also be provided with several anti-slip textures 13 to improve the friction for users to grip the box body 1, making it more convenient to use. The anti-slip textures 13 can be, for example,... Figure 3 The strip groove shown is multiple, and the multiple strip grooves are arranged at intervals on the bottom of the box body 1; of course, the anti-slip texture 13 can adopt other commonly used styles, and its setting position is not limited to the bottom of the box body 1, but can also be on the surface of the box lid, the side of the box body, etc., which will not be specifically described here.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
