Description

Technical Field

[0001] This utility model relates to the field of food storage container technology, specifically to a single-hand push-pull buckle type food storage container. Background Technology

[0002] Food storage containers are used to store food, typically made of materials such as plastic, glass, or stainless steel. They effectively isolate food from air, moisture, and bacteria, thus extending its freshness. Food storage containers usually have an airtight lid to maintain the taste and nutrients of food and prevent spoilage. Different materials are suitable for different needs; glass containers are better suited for microwave heating, while plastic containers are lightweight and portable. Food storage containers are widely used in kitchens and refrigerators to store ingredients and for takeout meals, making them convenient for everyday use.

[0003] Prior art document CN201720821153.1 discloses a food storage box, including a lid and a box body. The lid is fastened to the top edge of the box body. A retaining plate is connected to one side of the lid, and the retaining plate and the lid form an integral structure. A sealing ring is embedded in the inner wall of the lid. The sealing ring is coiled around to form a rectangular structure. After the lid moves laterally on the box body, the connecting device of the edge locks together. The retaining plate flips and fastens to the lower part of the top edge of the box body. The sealing ring presses against the top edge of the box body. The lid and the box body are pressed together by the sealing ring to form a sealed cavity.

[0004] The food storage container described in the prior art cannot be operated with one hand, and it has many locking points. All of these locking points need to be stressed and deformed, making it prone to fatigue damage after prolonged use and resulting in a short service life. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a single-handed push-pull buckle type food storage box, which can be operated with one hand during use, and only one set of locking positions requires force, while other locking positions do not require force when opening or closing, effectively improving service life.

[0006] The technical solution adopted by this utility model to solve its technical problem is a single-hand push-pull buckle type food storage box, including a glass box body and a plastic lid, wherein the plastic lid is provided at the upper end of the glass box body;

[0007] A flange is provided at the outer periphery of the top of the glass box body, and a hanging edge is provided at the outer periphery of the plastic cover body. An inner retaining edge is provided at the bottom of the plastic cover body near the inner side of the hanging edge. The inner retaining edge and the hanging edge are located on the inner and outer sides of the top of the flange, respectively. Strip-shaped protrusions A and B are symmetrically provided at both ends of the bottom of the flange. A notch is provided at one end of the hanging edge. A rotating component mounting groove is provided at the end of the plastic cover body near the notch. A buckle is provided in the rotating component mounting groove through a rotating shaft. A limiting ear is provided on the inner side of the buckle. A claw B is provided on both sides of the inner wall of the hanging edge near the notch. A claw A is provided on the end of the inner wall of the hanging edge away from the notch. Guide grooves are provided on both sides of the top of the flange. When the plastic cover body and the glass box body are in the closed state, the guide grooves and the claws B are staggered in the vertical direction.

[0008] By adopting the above technical solution, when it is necessary to close, the plastic cover is first pre-locked onto the top of the glass box using claws A and B. Then, the plastic cover is moved horizontally so that claws B and A are locked at the bottom of the flange. After that, by rotating the buckle with one hand, the limiting ear can be used to lock and seal the glass box and the plastic cover by engaging with one of the strip protrusions B or A, thus achieving one-handed operation.

[0009] Specifically, a limiting protrusion A is provided on both sides of the top of the inner edge, and a limiting protrusion B is provided at the bottom of the inner edge away from the notch.

[0010] By adopting the above technical solution, the limiting protrusion B can effectively limit the inner edge when it is locked to the inner wall of the glass box. Furthermore, since there is no protrusion at the end of the inner edge near the buckle, it can prevent the plastic cover from being interfered with when it is opened.

[0011] Specifically, a folded edge A is provided on the outer periphery of the glass box near the top.

[0012] Specifically, the top of the plastic cover has a folded edge B near the edge.

[0013] Specifically, the glass box is shaped like a rectangular boss that is wider at the top and narrower at the bottom, and the draft angle of the outer wall of the glass box is 8 degrees.

[0014] Specifically, a stress-reducing groove is provided on the inner side of the limiting ear near the center.

[0015] By adopting the above technical solution, the stress-reducing groove can reduce stress concentration and avoid damage when the limiting ear deforms during the opening and closing process. It also allows the limiting ear to have a larger elastic deformation space, reducing the possibility of fracture under stress.

[0016] The beneficial effects of this utility model are:

[0017] (1) The single-hand push-pull buckle type food storage box of this utility model, when it needs to be closed, aligns the protruding claw B at the bottom of the plastic cover with the guide groove, presses down, and moves the entire plastic cover horizontally towards the strip protrusion B or strip protrusion A, so that the protruding claw A and protruding claw B pre-lock the plastic cover. At this time, by rotating the rotating shaft, the buckle and the limiting ear are rotated. Through the cooperation of the limiting ear and the strip protrusion B, the plastic cover and the glass box are closed and sealed with one hand. Similarly, the plastic cover can be opened with one hand when needed. This food storage box can be operated with one hand when in use, and there is only one set of locking positions that need to bear force. Other locking positions do not need to bear force when opening or closing, which effectively improves the service life. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] To enable one-handed operation of this food storage container, reduce unnecessary stress points, and extend its lifespan, such as... Figure 1-6 As shown, the single-hand push-pull buckle type food storage box of this utility model includes a glass box body 1 and a plastic lid 3, wherein the plastic lid 3 is provided at the upper end of the glass box body 1.

[0028] A flange 20 is provided at the outer periphery of the top of the glass box 1. A hanging edge 5 is provided at the outer periphery of the plastic cover 3. An inner retaining edge 15 is provided at the bottom of the plastic cover 3 near the inner side of the hanging edge 5. The inner retaining edge 15 and the hanging edge 5 are located on the inner and outer sides of the top of the flange 20, respectively. Strip-shaped protrusions A11 and B12 are symmetrically provided at both ends of the bottom of the flange 20. A notch 6 is provided at one end of the hanging edge 5. A notch is provided at the end of the plastic cover 3 near the notch 6. The rotating component mounting groove 7 has a buckle 8 installed inside it via a rotating shaft 19. The buckle 8 has a limiting ear 9 on its inner side. The inner wall of the lower hanging edge 5 has protruding claws B13 near both sides. The inner wall of the lower hanging edge 5 has a protruding claw A10 at the end away from the notch 6. The top of the flange 20 has guide grooves 14 on both sides. When the plastic cover 3 and the glass box 1 are in the closed state, the guide grooves 14 and the protruding claws B13 are staggered in the vertical direction.

[0029] When in use, when it is necessary to close, first use the protruding claws A10 and B13 to pre-lock the plastic cover 3 onto the top of the glass box 1. Then move the plastic cover 3 horizontally so that the protruding claws B13 and A10 are locked at the bottom of the flange 20. Then, by rotating the buckle 8 with one hand, the limiting ear 9 can be used to lock and seal the glass box 1 and the plastic cover 3 by cooperating with one of the strip protrusions B12 or A11, thus achieving one-handed operation.

[0030] For example, such as Figure 5 As shown, the present invention also includes a limiting protrusion A16 on both sides of the top of the inner edge 15, and a limiting protrusion B17 on the bottom of the inner edge 15 away from the notch 6.

[0031] When in use, the limiting protrusion B17 can effectively limit the inner locking edge 15 when it is locked in the inner wall of the glass box 1. Furthermore, there is no protrusion on the end of the inner locking edge 15 near the buckle 8, which can prevent the plastic cover 3 from being interfered with when it is opened.

[0032] For example, such as Figure 1 As shown, the present invention also includes a folded edge A2 provided on the outer periphery of the glass box 1 near the top.

[0033] When in use, the overall strength of the glass box 1 can be increased by folding the edge A2.

[0034] For example, such as Figure 1As shown, the present invention also includes a folded edge B4 provided at the top edge of the plastic cover 3 near the edge.

[0035] When in use, the strength of the plastic cover 3 can be effectively improved by folding the edge B4.

[0036] For example, such as Figure 1 and Figure 4 As shown, the present invention also includes a glass box 1 with a shape that is wider at the top and narrower at the bottom, and the draft angle of the outer wall of the glass box 1 is 8 degrees.

[0037] When in use, setting the draft angle of the glass box 1 to 8 degrees can help the glass box 1 to be demolded more smoothly during production.

[0038] For example, such as Figure 6 As shown, the present invention also includes a stress-reducing groove 18 formed on the inner side of the limiting ear 9 near the center.

[0039] When in use, the stress-reducing slot 18 can reduce stress concentration and prevent damage when the limiting ear 9 deforms during the opening and closing process, and also give the limiting ear 9 a larger elastic deformation space, reducing the possibility of fracture under stress.

[0040] In use, when the plastic cover 3 needs to be closed, the protruding claw B13 at the bottom aligns with the guide groove 14 and moves downwards, causing the entire plastic cover 3 to move horizontally towards one end of the glass box 1. At this time, both the protruding claws A10 and B13 are engaged at the bottom of the flange 20, thus limiting the upward freedom of the plastic cover 3. Then, by rotating the rotating shaft 19, the buckle 8 and the limiting ear 9 rotate. The limiting ear 9 engages with one set of strip protrusions B12 or A11, thereby sealing the plastic cover 3 and the glass box 1 with one hand. The other set of strip protrusions A11 or B12 engages with the protruding claw A10, preventing the protruding claw A10 from moving in the front-back direction, which helps to improve the stability of the plastic cover 3 when it is closed and sealed.

[0041] When opening is required, simply rotate and pull open the latch 8, place your hand under the notch 6, and apply a horizontal force to the notch 6 near the guide groove 14. When the claw B13 moves to the lower end of the guide groove 14, apply an upward force to the notch 6. Since the plastic lid 3 can deform more easily at the end near the notch 6, it helps the user to more easily pull the plastic lid 3 upward, thus allowing the claw B13 to disengage more smoothly from the guide groove 14. This facilitates one-handed opening of the plastic lid 3. Compared to the comparative document, which has multiple locking positions that require force and cannot be operated with one hand, this food storage container can be operated with one hand and only has one set of necessary locking positions. Other points, such as the claws A10 and B13, do not require force and only require simple horizontal or vertical movement when opening or closing, effectively improving its service life.

[0042] The limiting protrusion B17 can effectively limit the inner locking edge 15 when it is locked to the inner wall of the glass box 1. Furthermore, the inner locking edge 15 has no protrusion near the buckle 8, which can prevent the plastic cover 3 from being interfered with when it is opened.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
