Description

Technical Field

[0001] This invention relates to the field of food storage container technology, and more specifically, to a food storage container with a rotating unlocking structure that can be opened with one hand. Background Technology

[0002] Currently, food storage containers are generally designed to be airtight, preventing outside air from entering and causing food to spoil faster. Existing food storage containers typically use a snap-on mechanism to open. This mechanism applies pressure to the seal on the lid, ensuring near-zero gap between the seal and the inner side of the container. However, this method of closing the lid creates pressure, forcing gas out and causing the internal pressure to be lower than the external pressure. Alternatively, when hot food is placed inside, the cooling process can cause the internal pressure to decrease due to slower molecular movement, further reducing the pressure. This pressure difference makes the lid difficult to open, requiring considerable effort and often necessitating the use of both hands to separate the container and the lid, making it inconvenient to open. Summary of the Invention

[0003] To address at least one of the aforementioned problems, the present invention first provides a single-handed opening food storage container with a rotating unlocking structure, comprising a container body, a top cover, and a rotating component. The top cover and the container body are detachably connected. The rotating component is horizontally rotatably connected to the top cover. The container body has a storage cavity for placing items. The top cover has an air hole communicating with the storage cavity. The rotating component has a sealing part adapted to be inserted into the air hole to seal it and form a sealed state. The air hole is located on the rotation path of the sealing part. The rotating component has a first guide part, and the container body has a second guide part that rotatably engages with the first guide part. The first guide part and / or the second guide part are arranged in a spiral downward configuration. When the rotating component is rotated, causing the sealing part to move away from the air hole, the storage cavity communicates with external air through the air hole to balance the air pressure. The rotating component causes the top cover to tilt relative to the container body, thereby facilitating opening the lid.

[0004] Optionally, the sealing part includes a connecting shaft and a sealing plug, the connecting shaft is fixed on the rotating part, and the sealing plug is sleeved on the connecting shaft.

[0005] Optionally, the circumferential wall of the rotating component is provided with a pushing portion that protrudes radially, and the side of the pushing portion near the sealing portion provides a contact surface for a finger to push the rotating component to rotate.

[0006] Optionally, the rotating component has a downwardly protruding connecting wall, the sealing part and the first guide part are respectively located at both ends of the connecting wall, the upper inner wall of the box body is provided with a connecting groove, the second guide part is provided on the connecting groove, and the connecting wall and the connecting groove are rotatably connected.

[0007] Optionally, the upper cover is provided with a limiting block, which is located on the rotation path of the connecting wall. The limiting block is adapted to abut against the bottom of the first guide portion to limit the rotation distance; and / or, the upper cover is recessed with a mounting cavity, the rotating component is rotatably accommodated in the mounting cavity, the mounting cavity is provided with an opening, the pushing portion extends out of the opening and rotates in the opening, the distance from the inner wall of the edge of the opening to the axis of rotation of the rotating component is less than the distance from the outer wall of the pushing portion to the axis of rotation of the rotating component, and the inner wall of the opening is adapted to abut against the outer wall of the pushing portion to limit the rotation distance of the pushing portion.

[0008] Optionally, the gap between the pushing part and the connecting wall forms an arc-shaped sliding cavity, and the sliding cavity is slidably connected to the upper edge of the box body.

[0009] Optionally, the box body is provided with a connecting wall, the second guide part is provided on the connecting wall, the bottom of the rotating part is provided with a limiting step, the first guide part is provided on the limiting step, and the connecting wall and the limiting step rotate and abut against each other.

[0010] Optionally, a smooth section is connected to both the first guide portion and the second guide portion, the smooth section being used to allow the sealing portion to be horizontally inserted into the air hole during rotation.

[0011] Optionally, the upper cover is provided with a mounting groove, and the bottom of the rotating component is provided with a mounting post. The mounting post is inserted into the mounting groove and rotatably connected to the mounting groove. The mounting post includes a first column and a second column arranged at intervals. The bottom of the first column and the second column are provided with a locking block. The bottom of the locking block is provided with an inclined guide surface. The peripheral wall of the mounting groove is provided with a limiting part protruding inward. The upper ends of the guide surface and the limiting part are slidably connected and guide the first column and the second column to move closer to each other and undergo elastic deformation until the locking block is engaged with the bottom of the limiting part.

[0012] Optionally, it also includes a sealing ring, and the peripheral wall of the upper cover is provided with a clamping groove for installing the sealing ring. The edge of the sealing ring protrudes from the clamping groove and is slidably connected to the inner wall of the box. When the upper cover moves the sealing ring down, the edge of the sealing ring unfolds and abuts against the inner wall of the box to maintain a sealing state.

[0013] Compared to existing technologies, the single-handed opening food storage container of this invention features a rotating unlocking structure. After placing food in the storage cavity and pressing the lid onto the container body, rotating the rotating component clockwise causes the sealing part to rotate and insert into the air inlet, sealing the air inlet and preventing external air from entering the storage cavity and accelerating food spoilage. When it is necessary to open the lid, rotating the rotating component counterclockwise causes the sealing part to pull out of the air inlet, releasing the seal and allowing the storage cavity to connect with the outside, balancing the air pressure and avoiding interference from pressure differences, making the lid easier to open.

[0014] When the sealing part blocks the air hole, the first guide part and the second guide part are aligned; when the sealing part moves away from the air hole and releases the seal, the first guide part slides along the second guide part until the lowest end of the first guide part rotates to the highest end of the second guide part. At this time, the rotating part causes one corner of the top cover to tilt upward relative to the box body, making the gap between the top cover and the box body larger. This not only accelerates the balance between the air pressure inside and outside the box, but also makes it easier for the user to apply force with the tilted top cover, allowing for easy opening of the cover with one hand.

[0015] This invention creates a system by simultaneously setting a sealing part and a first guide part that enables spiral descent on the rotating component, and setting a matching second guide part structure on the box body. This allows the rotating component to both release the seal and tilt or reverse the opening of the food storage box with a single horizontal rotation, achieving the purpose of one-handed one-button opening and one-button locking. This saves the time required for opening and locking the lid when the sealing part and the first guide part are set separately, which would otherwise be required for separate operations, and reduces the difficulty of operation.

Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] The accompanying drawings of the embodiments of the present invention provide a coordinate system XYZ, wherein the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0030] This invention provides a single-handed opening food storage container with a rotating unlocking structure, combined with... Figures 1 to 8As shown, the device includes a box body 1, a top cover 2, and a rotating component 3. The top cover 2 and the box body 1 are detachably connected. The rotating component 3 is horizontally rotatably connected to the top cover 2. The box body 1 has a storage cavity 11 for placing items. The top cover 2 has an air hole 21 communicating with the storage cavity 11. The rotating component 3 has a sealing part 31, which is adapted to be inserted into the air hole 21 to seal the air hole 21 and form a sealed state. The air hole 21 is located in the rotation path of the sealing part 31. The rotating component 3 is provided with a first guide portion 331, and the box body 1 is provided with a second guide portion 121 that rotatably cooperates with the first guide portion 331. The first guide portion 331 and / or the second guide portion 121 are arranged in a spiral downward configuration. When the rotating component 3 is rotated so that the sealing portion 31 is away from the air hole 21, the storage cavity 11 is connected to the outside air through the air hole 21 to balance the air pressure. The rotating component 3 drives the upper cover 2 to tilt up relative to the box body 1, thereby facilitating the opening of the cover.

[0031] like Figure 1 and 6 As shown, in Embodiment 1, after placing food in the storage cavity 11 and pressing the top cover 2 onto the box body 1, the rotating component 3 is rotated clockwise, causing the sealing part 31 to rotate and insert into the air inlet 21, sealing the air inlet 21 to form a sealed state and preventing external air from entering the storage cavity 11 through the air inlet 21, which would accelerate the spoilage of the food. When it is necessary to open the lid, the rotating component 3 is rotated counterclockwise, causing the sealing part 31 to be pulled out of the air inlet 21, releasing the seal and allowing the storage cavity 11 to connect with the outside, balancing the air pressure, avoiding interference from pressure differences, and making the top cover 2 easier to open.

[0032] Forward rotation is either clockwise or counterclockwise rotation, while reverse rotation is rotation in the opposite direction to forward rotation.

[0033] The first guide portion 331 extends downward from one end of the connecting wall 33 away from the sealing portion 31 to the other end to form a spiral wall. The first guide portion 331 and the second guide portion 121 have the same inclination direction. When the sealing portion 31 blocks the air hole 21, the first guide portion 331 and the second guide portion 121 are aligned. When the sealing portion 31 moves away from the air hole 21 and releases the seal, the first guide portion 331 slides along the second guide portion 121 until the lowest end of the first guide portion 331 rotates to the highest end of the second guide portion 121. At this time, the rotating component 3 causes one corner of the upper cover 2 to tilt upward relative to the box body 1, making the gap between the upper cover 2 and the box body 1 larger. This not only accelerates the balance between the air pressure inside and outside the box body 1, but also makes it easier for the user to apply force with the tilted upper cover 2, allowing for easy opening with one hand.

[0034] like Figure 2 and Figure 4As shown, in Embodiment 1, both the first guide portion 331 and the second guide portion 121 are arranged in a spiral downward configuration. In other embodiments, for example... Figure 2 The first guide section 331 is configured as a bottom smooth structure (i.e., combined with the smooth section 5 mentioned below), and the second guide section 121 is configured to descend in a spiral, so that the upper cover 2 can still be lifted during rotation.

[0035] In another embodiment, for example, Figure 4 The second guide portion 121 is configured with a smooth bottom structure (i.e., the same as the smooth portion 5 mentioned below). In this case, the bottom of the connecting groove 12 is a smooth structure, the connecting wall 33 on the rotating member 3 remains unchanged, and the first guide portion 331 is spirally descending. This allows the connecting wall 33 to still be accommodated in the connecting groove 12, and the first guide portion 121 and... Figure 4 The upper right side wall of the connecting groove 12 slides, causing the rotating part 3 to lift the upper cover 2 during rotation.

[0036] like Figure 2 , 5 As shown in Figure 6, optionally, the sealing part 31 includes a connecting shaft 311 and a sealing plug 312. The connecting shaft 311 is fixed on the rotating member 3, and the sealing plug 312 is sleeved on the connecting shaft 311. The axis of the connecting shaft 311 is arranged laterally, and the sealing plug 312 is made of silicone and is elastic. The end of the sealing plug 312 near the air hole 21 has a chamfer so that after the sealing plug 312 is inserted into the air hole 21, a sealing state is formed.

[0037] like Figure 2 As shown, optionally, the circumferential wall of the rotating member 3 is provided with a pushing part 32 protruding radially. The side of the pushing part 32 near the sealing part 31 provides a contact surface 321 for the finger to push the rotating member 3 to rotate.

[0038] like Figure 3 As shown, in Embodiment 1, the upper cover 2 is approximately a cuboid with rounded corners to prevent sharp corners from scratching the user. The rotating component 3 is located at any corner of the upper cover 2. A mounting cavity 25 is recessed at one corner of the upper cover 2, and the rotating component 3 is rotatably accommodated in the mounting cavity 25. The upper end of the rotating component 3 is circular or approximately circular, and the arc at the upper end of the rotating component 3 serves as a rounded corner at one end of the upper cover 2. The upper surface of the rotating component 3 is flush or nearly flush with the upper surface of the upper cover 2. This arrangement is not only aesthetically pleasing but also reduces the space occupied by the rotating component 3, allowing the rotating component 3 and the upper cover 2 to be cleverly combined.

[0039] The rotating part 3 is located at the corner of the upper cover 2. The user can hold the corner with one hand and press the contact surface 321 with the thumb. The rotating part 32 is pushed to rotate the rotating part to release the seal and lift the upper cover 2. It is simple and convenient and can be done with one hand.

[0040] like Figure 2 As shown, optionally, the rotating component 3 has a downwardly protruding connecting wall 33. The sealing part 31 and the first guide part 331 are respectively located at both ends of the connecting wall 33. The upper inner wall of the box body 1 is provided with a connecting groove 12, and the second guide part 121 is provided on the connecting groove 12. The connecting wall 33 and the connecting groove 12 are rotatably connected. In Embodiment 1, the connecting groove 12 is located at the upper corner of the inner wall of the box body 1. Without affecting food storage, the connecting groove 12 accommodates the connecting wall 33, reducing the external space occupied by the rotating component 3. When the rotating component 3 is rotated, so that the sealing part 31 is away from the air hole 21, the lowest end of the first guide part 331 rotates to the highest end of the second guide part 121, so that the rotating component 3 causes the upper cover 2 to tilt up.

[0041] like Figure 2 and Figure 3 As shown, optionally, the upper cover 2 is provided with a limiting block 22, which is located on the rotation path of the connecting wall 33. The limiting block 22 is adapted to abut against the bottom of the first guide part 331 to limit the rotation distance; and / or, the upper cover 2 is recessed with a mounting cavity 25, the rotating part 3 is rotatably accommodated in the mounting cavity 25, the mounting cavity 25 is provided with an opening, the distance from the inner wall of the edge of the opening to the rotation axis of the rotating part 3 is less than the distance from the outer wall of the pushing part 32 to the rotation axis of the rotating part 3, the pushing part 32 extends out of the opening and rotates in the opening, the inner wall of the opening is adapted to abut against the outer wall of the pushing part 32 to limit the rotation distance of the pushing part 32.

[0042] In Embodiment 1, the limiting block 22 restricts the extreme rotational position of the connecting wall 33, making the rotating structure more stable and reliable, and also giving the user a tactile prompt that the rotating part 3 has reached the extreme position.

[0043] like Figure 2 As shown, optionally, the gap between the pushing part 32 and the connecting wall 33 forms an arc-shaped sliding cavity 34, and the sliding cavity 34 is slidably connected to the upper edge of the box body 1.

[0044] In Embodiment 1, the pushing part 32 is located on the upper outer side of the box body 1, which is convenient for pushing rotation. At the same time, the sliding cavity 34 makes the sliding structure more stable and reliable, and restricts the connection position between the box body 1 and the rotating part 3 in the horizontal direction. When in a sealed state, the positional displacement between the box body 1 and the rotating part 3 is not easy to occur.

[0045] Optionally, a smooth section 5 is connected to both the first guide portion 331 and the second guide portion 121. The smooth section 5 is used to allow the sealing portion 31 to be horizontally inserted into the air hole 21 during rotation.

[0046] The smoothing part 5 is parallel or nearly parallel to the horizontal plane, and its length is adapted to the length of the air hole. When the smoothing part connected to the first guide part 331 slides with the smoothing part 5 connected to the second guide part 121, it is the process of the sealing part 31 being inserted into the air hole 21. This allows the sealing part 32 to be inserted deeper into the air hole 21, resulting in a better sealing effect. Compared to not having this structure, when rotating the rotating part 3, the sealing part 31 will be inserted into the air hole 21 at an angle. Due to the inclination between the sealing part 31 and the air hole 21, the sealing performance will be relatively worse than with this design.

[0047] like Figure 2 and Figure 3 As shown, optionally, the upper cover 2 is provided with a mounting groove 23, and the bottom of the rotating part 3 is provided with a mounting post 35, which is inserted into the mounting groove 23 and rotatably connected to the mounting groove 23.

[0048] In Embodiment 1, the axis of the mounting column 35 is the rotation axis of the rotating component 3. The rotating component 3 is rotatably mounted on the upper cover 2 so that it can detach from the box body 1 together with the upper cover 2 when the cover is opened, making it less likely to detach and be lost, while reducing the space occupied in the storage cavity 11.

[0049] like Figure 2 , Figure 3 and Figure 8 As shown, optionally, the mounting column 35 includes a first column 351 and a second column 352 spaced apart. The bottom of the first column 351 and the second column 352 are provided with a locking block 353. The bottom of the locking block 353 is provided with an inclined guide surface 354. The peripheral wall of the mounting groove 23 is provided with a limiting part 231 protruding inward. The upper ends of the guide surface 354 and the limiting part 231 are slidably connected and guide the first column 351 and the second column 352 to move closer to each other and undergo elastic deformation until the locking block 353 is engaged with the bottom of the limiting part 231.

[0050] In Embodiment 1, both the first column 351 and the second column 352 are approximately half the size of a cylinder. The gap between the first column 351 and the second column 352 allows space for the bottom of the first column 351 and the bottom of the second column 352 to elastically deform and move closer to each other. When installing the rotating component 3, the rotating component 3 is pressed downward into the mounting groove 23. When the locking block 353 slides below the limiting part 231, a slight vibration or slight sound will be generated between the mounting column 351 and the limiting part 231, indicating that the installation is in place. After installation, the limiting part 231 is positioned above the locking block 353, fixing the rotating component 3 vertically to the upper cover 2. This prevents the rotating component 3 from detaching without affecting its rotation, thus making the structure more stable.

[0051] like Figure 6 and Figure 8 As shown, optionally, a sealing ring 4 is also included. The upper cover 2 has a clamping groove 24 for installing the sealing ring 4 on its peripheral wall. The edge of the sealing ring 4 protrudes from the clamping groove 24 and is slidably connected to the inner wall of the box body 1. When the upper cover 2 moves the sealing ring 4 downward, the edge of the sealing ring 4 unfolds and abuts against the inner wall of the box body 1 to maintain a sealed state.

[0052] In Embodiment 1, the shapes of the box body 1, the top cover 2, and the sealing ring 4 are mutually compatible. The sealing ring 4 is made of silicone, preferably food-grade silicone. The clamping groove 24 clamps the sealing ring 4 from the top and bottom, and the outer side of the clamping groove 24 is open, allowing the edge of the sealing ring 4 to extend out of the clamping groove 24. When the top cover 2 is pressed down, the edge of the sealing ring 4 tilts upward and rubs against the inner wall of the box body 1, forming a seal with the box body 1.

[0053] like Figure 9 and Figure 10 As shown, in Embodiment 2, the box body 1 is provided with a connecting wall 33, the second guide part 121 is provided on the connecting wall 33, the bottom of the rotating part 3 is provided with a limiting step 36, the first guide part 331 is provided on the limiting step 36, and the connecting wall 33 and the limiting step 36 rotatably abut against each other. The connecting wall 33 protrudes from the outside of the box body 1, and the pushing part 32 serves as the side wall of the limiting step 36. By placing the connecting wall 33 on the outside of the box body 1 and providing a matching limiting step 36 structure on the upper cover 2, the inside of the box body 1 is easy to clean, and there are no residual contaminants due to dead corners. Except for the above content, the other parts of Embodiment 2 are the same as Embodiment 1, and will not be described again here.
