Description

Technical Field

[0001] This utility model relates to the field of food preservation, and in particular to a vacuum food preservation box. Background Technology

[0002] Vacuum food storage containers are storage devices used to preserve and keep food fresh. They are common household items nowadays. Because vacuum food storage containers can preserve food better, they are widely used in household products. There are many styles of vacuum food storage containers on the market, and their functions are also different.

[0003] However, currently used vacuum food storage containers are generally intended for individual use. When multiple vacuum food storage containers are used simultaneously, they are not convenient to handle together, and are scattered, making them inconvenient to retrieve. Although some can be stacked, they are not easy to stack and are prone to slipping. In addition, existing vacuum food storage containers are generally taller along the entire rib, resulting in an unattractive appearance.

[0004] Furthermore, existing vacuum food storage containers exhibit relatively significant deformation during vacuum sealing, affecting preservation effectiveness and making them prone to slipping when stacked. While some existing containers use internal ribs in the lid to increase strength and reduce deformation, these lids are difficult to clean. Additionally, existing vacuum food storage containers generally lack date settings, which can lead to confusion about usage dates when using multiple containers, making management inconvenient. Moreover, existing vacuum food storage containers are typically made of AS, ABS, or PET materials, making them susceptible to deformation or breakage under sudden temperature changes, thus failing to meet the requirements for microwave heating and refrigerator storage.

[0005] Therefore, there is an urgent need to develop a vacuum food preservation container. Utility Model Content

[0041] The present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the scope of the invention.

[0042] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0043] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a vacuum food storage box, including a box body 1, a box lid 2, and a vacuum valve 3.

[0044] Specifically, in combination Figures 5-7 As shown, the lid 2 is mounted on the body 1; the vacuum valve 3 includes a first silicone element 31, a second silicone element 32, a third silicone element 33, multiple protrusions 341, and multiple recesses 342. More specifically, the first silicone element 31 is connected to one side of the second silicone element 32; one end of the third silicone element 33 is mounted on the other side of the second silicone element 32; each of the protrusions 341 has a recess 342 connected to both sides, and the recesses 342 are located between two protrusions 341, forming a petal-shaped pressure relief element 34; the pressure relief element 34 is sleeved on the other end of the third silicone element 33.

[0045] Furthermore, the lid 2 has a through hole 21; the third silicone element 33 passes through the through hole 21; the first silicone element 31 and the second silicone element 32 are both located on the outside of the lid 2 (and also on one side of the through hole 21); the second silicone element 32 is adsorbed onto the lid 2 and is tightly attached to the lid 2; the end of the protruding portion 341 away from the recessed portion 342 is tightly attached to the inside of the lid 2 (and is located on the other side of the through hole 21 and inside the box body 1). In this embodiment, by having the end of the protruding portion 341 away from the recessed portion 342 tightly attached to the inside of the lid 2, gas inside the box body 1 can be discharged or gas outside the lid 2 can enter the box body 1, such as... Figure 7 The direction of the dashed arrow in the diagram indicates the direction of the gas flow.

[0046] Preferably, the first silicone component 31, the second silicone component 32, the third silicone component 33, and the pressure relief component 34 are all made of soft and elastic silicone material.

[0047] In addition, combined Figure 1 and Figure 7 As shown, in this embodiment, the first silicone part 31 is an annular structure with an arc-shaped protrusion 35 in the middle; the convex surface of the arc-shaped protrusion 35 is located on the outside of the box cover 2, and the concave surface of the arc-shaped protrusion 35 is connected to the inside of the box body 1 through the hollow structure.

[0048] The ring-shaped first silicone element 31 allows users to quickly release pressure simply by moving it by hand.

[0049] With the arc-shaped protrusion 35, when the vacuum food container is in a vacuum preservation state, the convex surface of the arc-shaped protrusion 35 is recessed, which makes it easy for users to observe whether the inside of the vacuum food container is in a vacuum preservation state.

[0050] In addition, in this embodiment, by gently moving the first silicone part 31 and the second silicone part 32, the second silicone part 32 is no longer attached to the lid 2, allowing external gas to enter the through hole 21 through the gap between the second silicone part 32 and the lid 2, and then smoothly enter the box body 1 through multiple recessed parts 342; at this time, the arc-shaped protrusion 35 is in a raised state, so that the user can easily observe that the vacuum food container is no longer in a vacuum state, and also prepare for the next vacuuming.

[0051] For the best options, please continue to refer to them. Figure 3 As shown, a sealing ring 4 is provided on the side of the box cover 2 that contacts the box body 1.

[0052] Furthermore, the sealing ring 4 has a textured surface, which further improves the sealing performance of the device. The texture can be diagonal, horizontal, or vertical stripes, etc., to achieve the same effect.

[0053] In addition, the sealing ring 4 can be detachably installed on the box cover 2 for easy disassembly and cleaning.

[0054] Preferably, the diameter of the through hole 21 is smaller than the diameters of the second silicone element 32 and the pressure relief element 34. The upper diameter of the third silicone element 33 is larger than the diameter of the through hole 21, and the lower diameter is smaller than the diameter of the through hole 21. The thickness of the through hole 21 is equal to the height of the third silicone element 33. This allows the second silicone element 32 to be tightly attached to the lid 2, the protruding portion 341 of the pressure relief element 34 to be tightly attached to the inner side of the lid 2, and the top and side surfaces of the third silicone element 33 to form an effective seal with the through hole 21 after vacuuming.

[0055] In addition, the second silicone element 32 and the pressure relief element 34 also adopt a special arc-shaped structure design. Specifically, the second silicone element 32 has an upwardly concave arc-shaped structure, and the pressure relief element 34 has a downwardly concave arc-shaped structure, i.e., a petal-like structure. This bidirectional arc-shaped structure design provides better sealing performance, maintaining good sealing even when no vacuum is applied.

[0056] Furthermore, the second silicone element 32, the third silicone element 33, and the pressure relief element 34 are all hollow structures. This allows the pressure relief element 34 to deform during the assembly of the vacuum valve 3, smoothly passing through the through hole 21 and thus making easy contact with the interior of the housing 1. It also allows for easy movement of the first silicone element 31 and the second silicone element 32, preventing the second silicone element 32 from adhering to the housing cover 2. This allows external gas to enter the through hole 21 through the gap between the second silicone element 32 and the housing cover 2, and then smoothly enter the housing 1 through multiple recessed portions 342.

[0057] Preferably, the lid 2 is made of PP material, the sealing ring 4 is made of hollow silicone, and the box body 1 is made of environmentally friendly PP material or high borosilicate glass material. The combination of these materials can make the device have a better preservation effect, and at the same time meet the needs of microwave heating and refrigerator preservation storage.

[0058] In one embodiment, the second silicone element 32 has an upwardly concave arcuate structure, and the arcuate structure has an outwardly expanding arcuate surface 320. The arcuate surface 320 can fit more tightly against the surface of the lid 2, forming an effective seal to prevent air and moisture from entering, thereby extending the shelf life of food.

[0059] In addition, combined Figures 1-2 as well as Figure 8 As shown, this embodiment also includes a date observation device. Specifically, the box cover 2 has an annular groove 6 on the side away from the box body 1; the date observation device is disposed in the annular groove 6; the through hole 21 and the vacuum valve 3 are both located in the middle of the annular groove 6 and the date observation device.

[0060] In a specific example, continue to refer to Figure 1 and Figure 2 As shown, the date observation device includes a date scale component 53 and an indicator component 54; the date scale component 53 is integrally formed with the box cover 2; the date scale component 53 includes a date scale area disposed in the annular groove 6; the indicator component 54 is fixedly connected to the second silicone component 32 of the vacuum valve 3, and the indicating end points to the date scale area. The indicator component 54 may be triangular, with the indicating end being... Figure 9 The central indicator 54 is oriented toward the tip of the date scale area.

[0061] In another specific example, combined Figure 8 and Figure 9 As shown, the date observation device includes a date dial 51 and multiple movable parts 52. Specifically, the date dial 51 is engaged in the annular groove 6; the date dial 51 includes a month scale area and a date scale area; one of the movable parts 52 is slidably disposed on the month scale area, and the other movable part 52 is slidably disposed on the date scale area.

[0062] Preferably, the date dial 51 is ring-shaped, which makes it easy to directly snap into the ring groove 6.

[0063] In this embodiment, reference continues to be made to Figure 8 and Figure 9 As shown, the movable component 52 includes a first connector 521, a second connector 522, and a third connector 523. Specifically, one end of the first connector 521 is connected to one end of the second connector 522, and the other end of the first connector 521 is provided with a U-shaped groove 5210 for separately displaying the month and date on the date dial 51; the other end of the second connector 522 is connected to the third connector 523; the date dial 51 is snapped between the first connector 521 and the third connector 523.

[0064] In one embodiment, only one number can be displayed or circled within the U-shaped groove 5210. For example, there are two movable parts 52. Specifically, when it is necessary to record the storage date of food in the vacuum-sealed food container, simply slide the two movable parts 52 respectively, one to indicate the month of storage and the other to indicate the date of storage, and the specific storage time can be displayed. Then, the freshness of the food can be determined based on the displayed month and day.

[0065] In one embodiment, the lid 2 is provided with fasteners 22 around its perimeter for securing the sidewalls of the box body 1. Specifically, the fasteners 22 are provided with engaging grooves that can engage the sidewalls of the box body 1.

[0066] In addition, the overall shape of a vacuum food storage container can be rectangular or circular, such as... Figure 1 , Figure 10 and Figure 11 As shown, the overall size and shape can be set according to actual needs.

[0067] In this embodiment, as Figure 12 As shown, the top of the box cover 2 is a dome structure, and the highest point of the dome structure is higher than the edge of the box cover 2.

[0068] In this embodiment, the vacuum food storage container is initially in the following state: Figure 12 As shown, the central surface of the lid 2 has a curvature (i.e., the lid 2 is a dome-shaped structure or a dome structure), and the curvature is... Figure 12As shown by the solid line arc, the lid 2 is raised around its entire perimeter, allowing it to enclose the bottom of the container 1 under vacuum, achieving a stackable and non-slip effect. Specifically, when multiple vacuum food storage containers need to be stacked, a vacuum pump is installed on the vacuum valve 3 to perform a vacuuming operation. At this time, the gas inside the vacuum food storage container, under the action of the vacuum pump, exits from the inside of the container 1 through the recessed portion 342, the through hole 21, and the gap between the second silicone piece 32 and the lid 2. This gas is then observed through the recessed area of ​​the arc-shaped protrusion 35 (as shown in the image). Figure 12 (When the arc-shaped protrusion 35° is depressed under the action of force F, it can be known that the vacuum food container is in a vacuum state.) The surface of the lid 2 is at this time flat. Figure 12 As shown by the dashed line, the surface is no longer curved, thus enabling the stacking of multiple vacuum food storage containers.

[0069] Then, by manually moving the first silicone component 31, a gap is created between the second silicone component 32 and the lid 2, allowing gas to pass through the gap between the second silicone component 32 and the lid 2, the through hole 21, and the recessed portion 342 into the interior of the box body 1, thereby depressurizing the device.

[0070] In summary, the vacuum food storage container proposed in this utility model has the following advantages:

[0071] The device comprises a box body, a lid, and a vacuum valve; the lid is mounted on the box body; the vacuum valve includes a first silicone element, a second silicone element, a third silicone element, multiple protruding portions, and multiple recessed portions; one side of the first silicone element is connected to one side of the second silicone element; one end of the third silicone element is mounted on the other side of the second silicone element; each protruding portion has a recessed portion connected to both sides, the recessed portion being located between two protruding portions, forming a petal-shaped pressure relief component; the pressure relief component is fitted onto the other end of the third silicone element; the lid has a through hole; the third silicone element passes through the through hole; both the first and second silicone elements are located on the outside of the lid; the second silicone element is adsorbed onto the lid and tightly adheres to it; the ends of the protruding portions away from the recessed portions are tightly adhered to the inside of the lid. This device not only achieves vacuum preservation but also improves sealing through the vacuum valve and is easy to stack.

[0072] In addition, the arc-shaped protrusion in the middle of the first silicone part allows observation of whether the vacuum food container is in a vacuum state.

[0073] In addition, by setting the date observation device, the date when food is stored can be set each time, so that the freshness of the food can be judged by observing the usage date later.
