Abstract
Description
Technical Field
[0001] This utility model relates to food storage containers, and more particularly to a food storage container that opens the vent while simultaneously opening the lid, and automatically closes the vent when closing the lid. Background Technology
[0002] Food storage containers are not only convenient and practical, but they also allow food to be stored in different categories. As people's quality of life continues to improve, there are more and more types of food storage containers available.
[0003] Most existing food storage containers require opening the vent first, then using both hands to grip the edge of the lid, which involves multiple steps to open. To simplify opening, a prior patent (CN 223303262 U) proposed a food storage container that allows for one-handed venting and lid opening, effectively improving ease of use. However, the applicant found that this food storage container still requires either opening the vent first and then opening the lid, or closing the lid first and then closing the vent, requiring two steps and making it relatively cumbersome and inconvenient for quick operation.
[0004] To achieve rapid opening of the vent and opening of the lid simultaneously, and automatic closing of the vent when the lid is closed, an improved food storage container needs to be proposed. Summary of the Invention
[0005] To address the aforementioned deficiencies in the existing technology, this utility model proposes an improved food storage container that simultaneously opens the lid when the vent is opened and automatically closes the vent when the lid is closed. The structure of the lid and the valve buckle is further optimized, enabling rapid opening of the vent and lid simultaneously, with the vent automatically closing when the lid is closed. The solution is as follows: A food storage container with an open vent and an automatically closing vent, comprising a container body, a lid, and a valve buckle. The container body and lid are connected by a sealing strip. The lid has an vent, which is connected to the valve buckle by a sealing bead. A recessed groove is formed at the top of the lid, and a channel extends from the recessed groove near the side wall of the lid, penetrating the side wall of the lid. The vent is located at the bottom of the recessed groove, and a pin is provided inwardly on the side wall of the recessed groove. A connecting structure is integrally formed at the bottom of the valve buckle near the side wall of the recessed groove. The side wall of the connecting structure has a slot and an arc-shaped groove. The slot is rotatably connected to the pin, and the arc-shaped groove is adapted to an arc-shaped protrusion at a corresponding position on the side wall of the recessed groove. One end of the valve buckle is inserted into the channel so that the end of the valve buckle is located between the lid and the container body, and a sealing bead is provided on the valve buckle for sealing the vent. Pull the air valve latch upwards to open the vent. Simultaneously, the portion of the air valve latch located within the slot will pry open the lid. Closing the lid will automatically close both the air valve latch and the vent. This structural improvement allows for quick opening of the vent and lid simultaneously, with the vent automatically closing when the lid is closed. It's a one-step process, making it more convenient and easier to use, requiring less force and making it ideal for women and children with limited strength.
[0006] Furthermore, the top of the lid is designed with a high outer edge and a low inner edge. The groove extends close to and penetrates the side wall of the lid, but the slightly higher outer ring of the lid remains intact. This creates a unified and aesthetically pleasing shape for the top of the lid, which not only makes it easier to stack the boxes on the lid but also simplifies the lid's mold and reduces investment costs.
[0007] Furthermore, the valve buckle is provided with a protrusion on which a valve sealing plug can be detachably installed. When cleaning or replacing, simply remove the valve sealing plug. This type of sealing plug is convenient to use and maintain.
[0008] Furthermore, the valve sealing bead is integrally provided with a funnel-shaped sealing wing in the circumferential direction. In use, the valve sealing bead is inserted into the exhaust hole, and the sealing wing is pressed against the bottom surface of the groove around the exhaust hole, which can further enhance the sealing performance of the valve sealing bead to the exhaust hole.
[0009] Furthermore, the slot includes a transition slot and a connecting slot. This facilitates a smooth fit between the pin and the slot, allowing the valve latch to be better assembled and rotated with the lid.
[0010] Furthermore, two limiting posts are symmetrically arranged on the side wall of the settling tank to ensure that the air valve buckle and the main body of the box cover are flush when closed.
[0011] Furthermore, an installation groove is provided at the bottom of the lid, and several sealing strip positioning grooves are provided around the bottom edge of the installation groove near the box body. The installation groove is surrounded by a sealing strip, and a sealing strip positioning protrusion is provided on one side of the sealing strip to cooperate with the reinforcing sealing groove. The sealing strip is pressed against the inner wall of the box body to form a water-tight function, which extends the freshness preservation time.
[0012] Furthermore, the upper surface of the valve buckle is also provided with an indicator, the position of which corresponds to the sealing plug, effectively guiding the user to align the sealing plug with the quick-insertion vent.
[0013] Compared with the prior art, the advantages of this utility model are as follows: This invention improves the structure of the connection between the lid and the valve buckle. When the valve buckle is turned, the exhaust hole is opened and the lid is opened at the same time. When the lid is closed, the exhaust hole is automatically closed. No great force is required to operate this way. It is also very user-friendly for people with less strength, such as women and children. It can quickly open the exhaust hole and open the lid at the same time, and automatically close the exhaust hole when the lid is closed, making it more convenient to use. Attached Figure Description

[0016] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0017] like Figure 1 As shown, this utility model discloses a food storage box that opens the vent and opens the lid simultaneously, and automatically closes the vent when the lid is closed, including a box body 2, a lid 1, and a valve buckle 3.
[0018] like Figure 2 , 3 As shown, a recessed groove 11 is provided on the top of the box cover 1, and a groove channel 111 extends into the recessed groove 11 near the side wall of the box cover. The groove channel 111 penetrates the side wall of the box cover, and an exhaust hole 112 is provided on the bottom surface of the recessed groove. A pin 113 and an arc-shaped protrusion 114 are provided inward on the side wall of the recessed groove.
[0019] like Figure 2 As shown, in order to ensure that the air valve buckle 3 and the main body of the box cover are flush when closed, two limit posts 10 are symmetrically arranged on the side wall of the sink.
[0020] like Figure 1 , 4 As shown in Figure 5, a valve buckle 3 is detachably mounted on the cover 1. A connecting structure 32 is integrally formed on the bottom surface of the valve buckle near the side wall of the settling tank. The side wall of the connecting structure has a slot 321 and an arc-shaped groove 322. The slot 321 is rotatably connected to the pin 113, allowing the valve buckle 3 to rotate relative to the cover 1. The arc-shaped groove 322 is adapted to the arc-shaped protrusion 114 located at a corresponding position on the side wall of the settling tank 11. The protruding end 31 of the valve buckle 3 is inserted into the slot channel 111 so that the end of the valve buckle is located between the cover 1 and the box body 2. The valve buckle 3 is provided with a sealing bead 33 for sealing the exhaust port 112.
[0021] The top of the lid is high on the outside and low on the inside. The groove channel 111 penetrates the side wall of the lid but does not damage the slightly higher outer ring of the lid 1. The outer ring remains intact. In this way, the top of the lid not only maintains an integrated and beautiful shape, but also makes it convenient for the box body 2 to be stacked on the lid 1. It also simplifies the mold for forming the lid 1 and reduces the investment cost.
[0022] By using a slot 321 on the connecting structure 32, the strength of the rotating part is increased. At the same time, the upper part of the protruding end 31 abuts against the outer ring of the cover 1 to form a protective structure, so that the buckle will not fall off due to accidental contact.
[0023] The upper and lower surfaces of the protruding end 31 abut against the lid 1 and the box body 2, respectively. When the air valve buckle 3 rotates, it forms an approximate lever, prying open the lid 1. The arc-shaped groove 322 is adapted to the arc-shaped protrusion 114 located at the corresponding position on the side wall of the recess 11, see [reference]. Figure 6 When the air valve latch 3 seals the exhaust port 112, the arc-shaped protrusion 114 is inside the arc-shaped groove 322. When the exhaust port 112 is opened, the arc-shaped groove 322 moves away from the arc-shaped protrusion 114. This design allows for a clear sense of the valve latch 3 when it is opened or closed, and the air valve latch 3 is flush with the surface of the cover 1 when it is closed.
[0024] Specifically, the valve buckle 3 has a protrusion on which a valve sealing bead 33 can be detachably installed. For cleaning or replacement, simply remove the valve sealing bead 33, making use and maintenance convenient. The valve buckle 3 is a one-piece molded structure; the valve sealing bead 33 is then installed during use. The valve sealing bead 33 has flared sealing wings circumferentially. During use, the valve sealing bead 33 is inserted into the exhaust hole, and the sealing wings press against the bottom surface of the recess around the exhaust hole, further enhancing the sealing performance of the valve sealing bead 33 on the exhaust hole 112.
[0025] Specifically, card slot 321 includes a transition slot and a connecting slot, see [link / reference] Figure 4 , 5This facilitates a smoother fit between the pin 113 and the slot 321, allowing the valve buckle 3 to be better assembled and rotated with the cover 1.
[0026] In one embodiment, the upper surface of the valve buckle 3 is also provided with a marking section (not shown in the figure). The marking section is positioned corresponding to the sealing plug, effectively guiding the user to align the sealing plug with the quick-insertion vent hole 112. The marking section can be a graphic, a hole, text, etc., as long as it serves an identification function.
[0027] like Figure 7 , 8 As shown, a mounting groove 13 is formed at the bottom of the lid 1. Several sealing strip positioning grooves 131 are also provided circumferentially around the bottom edge of the mounting groove 13 near the box body. A sealing strip 12 is circumferentially mounted on the mounting groove 13. A sealing strip positioning protrusion 121 that mates with the sealing strip positioning groove 131 is provided on one side of the sealing strip 12. The sealing strip 12 presses against the inner wall of the box body 2, forming a water-tight seal. Through the structural optimization of the air valve sealing bean 33 and the sealing strip 12, the preservation time is extended.
[0028] Specifically, the main body of the lid 1 is a one-piece molded structure, and the sealing strip 12 is then fitted on it during use.
[0029] like Figure 7 , 9 The image shows the open / closed state of the food storage container. Figure 7 The lid 1 of the food storage container is in the closed state, that is, in a completely sealed state; Figure 9 With the lid 1 open, using the lever principle, pry the end of the air valve latch 3 away from the protruding end 31 with one hand. The air valve latch 3 rotates relative to the lid 1, opening the vent. The air valve latch 3 then pries open the lid 1, allowing it to be easily opened. Conversely, when the lid 1 is closed, the edge of the box body 2 abuts against the protruding end 31 of the air valve latch 3. The air valve latch 3 rotates relative to the lid 1, closing the lid and simultaneously closing the vent.
[0030] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
