Description

Technical Field

[0001] This utility model relates to the field of food storage container technology, specifically to a vacuum-sealed food storage container and a sealed food storage container lid. Background Technology

[0002] Existing food storage containers have many defects and fail to meet the needs. In terms of sealing, most use simple snap-fit ​​and basic sealing rings, which have poor fit and are prone to aging and deformation. The failure of the seal allows air to seep in, accelerating food spoilage. They cannot achieve vacuum preservation. Some products with vacuum function have low integration between the vacuum structure and the lid, making it easy for air to leak. The vacuum breaking operation is cumbersome. The lids are mostly opaque or the transparent area is not well-designed, requiring opening the lid to observe the inside, which damages the preservation environment. The boxes do not have markings, making it inconvenient to store quantities. In addition, some materials are not food-grade, posing safety hazards. The structure has poor durability and is prone to loosening after repeated use, shortening its lifespan. Utility Model Content

[0003] In view of the problems existing in the above-mentioned vacuum-sealed food storage containers and sealed food storage container lids, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a vacuum-sealed food storage box and a sealed food storage box lid, which solves the problems of poor fit and easy aging and deformation of the sealing rings that are often used with simple fastening and basic sealing rings.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A vacuum-sealed food storage container and a sealed food storage lid, comprising a container body and a vacuum pump, wherein the container body is provided with a lid at the top, the lid includes a wrapping pad and a glass plate, a sealing gasket is fixedly provided at the bottom of the wrapping pad, the glass plate is snapped into the wrapping pad, an opening is fixedly provided at the top of the glass plate, a sealing plug is fixedly provided in the opening, a vacuum pump is provided at the top of the lid, and scale lines are fixedly provided on the outer wall of the container body.

[0006] Preferably, the box body is made of rigid glass.

[0007] Preferably, the wrapping pad is a silicone pad, and the thickness of the wrapping pad is 5mm.

[0008] Preferably, a sealing ring is fixedly provided at the bottom of the sealing plug, and the sealing ring is a silicone ring.

[0009] Furthermore, the sealing plug is made of silicone.

[0010] Preferably, a placement pad is fixedly provided on the top of the sealing plug.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This utility model features a box lid with a silicone pad, a sealing pad, and a sealing plug with a silicone sealing ring. The silicone material can fit tightly against the box body and the glass plate. The silicone exhaust valve with the exhaust hole can be connected to a vacuum pump to create a vacuum, reducing the air inside the box, inhibiting the growth of microorganisms and the oxidation of food, and solving the problems of poor sealing and short preservation period of traditional food storage boxes.

[0012] This invention features a transparent glass plate embedded in the lid, allowing observation of the food's condition without opening the lid, thus avoiding frequent opening that could disrupt the seal or vacuum environment. The outer side of the box is marked with graduations to facilitate precise control of the amount of liquid or quantitative food stored, meeting diverse storage needs.

[0013] This utility model features a box body made of high-strength glass, with the wrapping gasket, sealing gasket, and sealing plug all made of silicone, meeting food-grade requirements and ensuring safe use. The box body can be opened by manually lifting the sealing plug to break the vacuum, without the need for tools, making it convenient to operate. At the same time, the high-strength glass and durable silicone material also extend the product's service life. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a vacuum-sealed food storage box and a sealed food storage box lid.

[0019] This utility model provides, for example Figure 1-3The vacuum-sealed food storage container and lid shown include a container body 1 and a vacuum pump 2. The container body has a lid 3 on top, which includes a protective pad 4 and a glass plate 5. A sealing gasket 6 is fixedly attached to the bottom of the protective pad 4, and the glass plate 5 is snapped into the protective pad 4. An opening 7 is fixedly attached to the top of the glass plate 5, and a sealing plug 8 is fixedly attached to the opening 7. The vacuum pump 2 is located on the top of the lid 3. Graduation lines 9 are fixedly attached to the outer wall of the container body 1. After placing the food to be stored into the high-strength glass container body 1, the lid 3, composed of the silicone protective pad 4 and the embedded glass plate 5, is placed on top. The silicone sealing gasket 6 at the bottom of the lid 3 fits tightly against the top edge of the container body 1. Simultaneously, the snap-fit ​​structure of the protective pad 4 and the glass plate 5 ensures that the lid 3 and the container body 1 form a preliminary seal, preventing the initial infiltration of outside air. The vacuum pump 2 is then used to connect the lid 3. When the vacuum pump 2 is activated, air inside the box is drawn out through the opening 7 on the glass plate 5. At this time, the silicone sealing ring 10 at the bottom of the silicone sealing plug 8 inside the opening 7 prevents air leakage from the gap between the sealing plug 8 and the opening 7 during the vacuuming process, ensuring effective air removal and gradually creating a vacuum environment. This reduces the conditions for food oxidation and microbial growth. After vacuuming is complete, the vacuum pump 2 is removed. The silicone sealing plug 8, due to its own elasticity and the negative pressure inside the box, automatically and tightly seals the opening 7. Combined with the bottom sealing ring 10, this further enhances the sealing effect. Simultaneously, the silicone pad 4 on the lid 3 remains in close contact with the box body 1. This double-sealing structure maintains the vacuum state inside the box, achieving long-term food preservation. To open the food storage box, manually lift the sealing plug 8 upwards. Outside air enters the box through the opening 7, balancing the air pressure inside and outside the box, allowing the lid 3 to be easily opened without the need for additional tools. For greater durability, such as Figure 1-3 As shown, the box body 1 is made of rigid glass.

[0020] For easier use, such as Figure 1-3 As shown, the wrapping pad 4 is made of silicone and has a thickness of 5mm.

[0021] For better sealing, such as Figure 1-3 As shown, a sealing ring 10 is fixedly provided at the bottom of the sealing plug 8, and the sealing ring 10 is a silicone ring.

[0022] Finally, to ensure a better seal for the sealing plug 8, such as... Figure 1 As shown, the sealing plug 8 is a silicone plug, and a placement pad 11 is fixedly provided on the top of the sealing plug 8.

[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
