Description

Technical Field

[0001] This utility model relates to the field of food storage technology, and in particular to a sealed storage container. Background Technology

[0002] Sealed storage containers are used to store food, preventing it from becoming damp and moldy by isolating it from air. They are widely used in daily life. Common sealed storage containers employ a "fixed sealing ring + movable rubber stopper" structure. Specifically, the sealing ring is fixed to the lid, so that when the container and lid are closed, the inside of the container is isolated from the outside, forming a sealed space to store the food. This also creates a pressure difference between the inside and outside of the container, making the lid difficult to open. Simultaneously, the lid has a ventilation channel with a movable rubber stopper inside, controlling the flow of air between the inside and outside of the container by opening and closing the stopper. In existing technology, the control structure for the rubber stopper requires levers, multiple springs, etc., resulting in numerous components and a complex structure, leading to low production efficiency.

[0022] Common airtight storage containers employ a "fixed sealing ring + movable rubber stopper" structure. Specifically, the sealing ring is fixed to the lid, so that when the container and lid are closed, the interior of the container is isolated from the outside, forming a sealed space for the sealed storage of food. This also creates a pressure difference between the inside and outside of the container, making the lid difficult to open. Simultaneously, the lid has a ventilation channel with a movable rubber stopper within it, controlling the flow of air between the inside and outside of the container by opening and closing the stopper. In existing technologies, the control structure for the rubber stopper requires levers, multiple springs, etc., resulting in numerous components and a complex structure, leading to low production efficiency.

[0023] To solve the above-mentioned technical problems, this utility model proposes a sealed storage tank.

[0024] Please see Figures 1 to 11 In one embodiment of the present invention, the sealed storage container includes a container body 10 and a lid assembly 20, wherein a sealing ring 30 is fixedly provided on the outer periphery of the lid assembly 20, and the sealing ring 30 is used to make the container body 10 and the lid assembly 20 cover each other to form a closed space 11. Specifically, the cover assembly 20 includes: The upper cover 40 and the lower cover 50 are fixedly connected to each other, and the upper cover 40 and the lower cover 50 form an installation cavity 21; the lower cover 50 has a through hole 51, which connects the installation cavity 21 and the enclosed space 11. Pressing member 60 is movably connected to upper cover 40; there is a movable gap 44 between pressing member 60 and upper cover 40, and the movable gap 44 is connected to mounting cavity 21; on the one hand, the movable gap 44 can ensure that pressing member 60 can slide smoothly relative to upper cover 40, and on the other hand, the mounting cavity 21 is connected to the outside through the movable gap 44. Rubber plug 70 is movably connected to the lower cover 50; A press-type transmission structure 80 is disposed in the mounting cavity 21. The press member 60 is interconnected with the rubber stopper 70 through the press-type transmission structure 80 assembly. By pressing once and pressing twice, the press member 60 can move the rubber stopper 70 to a first position and a second position. When the rubber stopper 70 moves to the first position, the rubber stopper 70 seals the through hole 51. When the rubber stopper 70 moves to the second position, the rubber stopper 70 releases the sealing treatment of the through hole 51, so that the through hole 51, the mounting cavity 21 and the movable gap 44 are connected in sequence to form a ventilation channel.

[0025] The technical solution of this utility model sets up a press-type transmission structure 80 to connect the press member 60 and the rubber stopper 70. The press-type transmission structure 80 adopts a press-type retractable pen refill structure similar to that of a ballpoint pen. By pressing the press member 60 once and pressing it twice, the rubber stopper 70 can be switched between a first position and a second position. When the rubber stopper 70 moves to the first position, the end of the rubber stopper 70 abuts against the end of the through hole 51 to seal the through hole 51. At this time, the sealed space 11 forms a sealed structure for the sealed storage of food. When the rubber stopper 70 moves to the second position, the end of the rubber stopper 70 releases its abutment against the end of the through hole 51 to release the sealing treatment of the through hole 51, so that the through hole 51, the mounting cavity 21 and the movable gap 44 are connected in sequence to form a ventilation channel. At this time, since the sealed space 11 is in a ventilated state, the user can easily open the cover assembly 20. Since the retractable refill structure of a ballpoint pen has few parts and a simple structure, using it as the retractable transmission structure 80 of this application to control the rubber stopper 70 can simplify and improve the control structure of the rubber stopper 70, thereby improving production efficiency.

[0026] Specifically, the upper cover 40 is provided with a connecting channel 41, and the inner wall of the connecting channel 41 is alternately provided with a first guide groove 411 and a second guide groove 412 along the circumferential direction, wherein the groove depth of the first guide groove 411 is greater than the groove depth of the second guide groove 412; the pressing member 60 includes a driving rod 61 having a first hollow structure 613, the driving rod 61 is coaxially disposed inside the connecting channel 41, and the driving rod 61 can slide axially relative to the connecting channel 41; a plurality of guide members 611 are circumferentially protruding from the driving rod 61, and the guide members 611 are slidably connected in the first guide groove 411 and / or the second guide groove 412; the end of the driving rod 61 is provided with a serrated structure 612; the pressing transmission structure 80 includes a transmission assembly 90 and a reset elastic member 10. The transmission assembly 90 includes a rotating rod 91, a first transmission member 92, and a second transmission member 93, which are coaxially connected in sequence. At least a portion of the rotating rod 91 is coaxially disposed in the first hollow structure 613 of the drive rod 61, and the rotating rod 91 can slide axially relative to the drive rod 61. The exposed portion of the rotating rod 91 is provided with a plurality of rack portions 911 protruding outward in a circumferential direction. The ends of the rack portions 911 abut against the sawtooth structure 612, and the rack portions 911 can slide in connection with the first guide groove 411 and / or the second guide groove 412. The second transmission member 93 is used to connect with the rubber stopper 70. The reset elastic member 100 is disposed between the first transmission member 92 and the inner wall of the mounting cavity 21, and the reset elastic member 100 is used to drive the rotating rod 91 to move in the direction of the drive rod 61. With this configuration, a retractable refill structure similar to that of a ballpoint pen is formed, thereby ensuring the smooth implementation of the technical solution of this application. Since the guide member 611 of the drive rod 61 is always restricted to sliding within the first guide groove 411 and / or the second guide groove 412, the drive rod 61 can only move axially during the entire control process of the rubber stopper 70. At least a portion of the rotating rod 91 is slidably connected to the first hollow structure 613 of the drive rod 61, and the rotating rod 91 abuts against the serrated structure 612 through the end of its rack portion 911. Under the drive of the serrated structure 612, the rotating rod 91 can rotate. That is, during the entire control process of the rubber stopper 70, the rotating rod 91 can simultaneously perform axial movement and circumferential rotation. The reset elastic member 100 serves as the driving force for the axial movement of the rotating rod 91 towards the drive rod 61 after being pressed, ensuring that the end of the rack portion 911 of the rotating rod 91 can effectively abut against the serrated structure 612, thereby causing the rotating cylinder to rotate circumferentially under the action of the serrated surface 6121 of the serrated structure 612.

[0027] Furthermore, a first inclined surface 9111 is provided at the end of the rack portion 911 facing the sawtooth structure 612, and the first inclined surface 9111 abuts against the sawtooth surface 6121 of the sawtooth structure 612; and a protruding protrusion 413 is formed between any adjacent first guide groove 411 and second guide groove 412, and a second inclined surface 4131 is provided at one end of the protrusion 413 facing the rack portion 911, and the first inclined surface 9111 abuts against the second inclined surface 4131. This arrangement ensures that the rack portion 911, under the inclined guidance of the sawtooth surface 6121 and the second inclined surface 4131, drives the rotating rod 91 to rotate circumferentially.

[0028] Furthermore, the reset elastic element 100 is configured as a compression spring, and is sleeved on the outside of the rubber plug 70; and the first transmission member 92 has a disc-shaped structure, with a limiting part 921 extending from the circumferential edge of the first transmission member 92 towards the second transmission member 93, the limiting part 921 being used to restrict the radial movement of the reset elastic element 100. This configuration, using a commercially available compression spring as the reset elastic element 100, results in a simple structure and strong practicality. Simultaneously, the limiting part 921 extending from the circumferential edge of the disc-shaped first transmission member 92 gently holds the outer diameter of the compression spring, forming a radial positioning, ensuring that the compression spring does not wobble or become unstable and bent during compression / reset, guaranteeing smooth pressing next time.

[0029] The specific operating steps of the press-type transmission structure 80 are described below with reference to the above embodiments; In the initial state, the rack portion 911 of the rotating rod 91 rests in the first guide groove 411. Due to the deep groove of the first guide groove 411, the reset elastic member 100 lifts the transmission assembly 90, and the rotating rod 91 inserts into the area of ​​the first hollow structure 613 of the drive rod 61, so that the rubber stopper 70 can be moved away from the through hole portion 51. The closed space 11 of the can body 10 is kept open to the outside through the through hole portion 51-installation cavity 21-moving gap 44, and the lid can be opened easily.

[0030] When the user presses the button 60 for the first time, the drive rod 61 slides down along the first guide groove 411 / second guide groove 412 via the guide member 611. Simultaneously, the serrated structure 612 of the drive rod 61 pushes the rack portion 911 of the rotating rod 91 down along the first guide groove 411. When the rotating rod 91 slides until the rack portion 911 disengages from the first guide groove 411, the first inclined surface 9111 at the end of the rack portion 911 aligns with the serrated surface 6121 of the serrated structure 612 at the end of the drive rod 61, forcing the rotating rod 91 to rotate a certain angle along the serrated surface 6121 of the serrated structure 612. The first inclined surface 9111 of the rack portion 911 is aligned with the second inclined surface 4131 of the protrusion 413, and rotates to align with the second guide groove 412 under the continued guidance of the second inclined surface 4131 of the protrusion 413. After releasing, the reset elastic member 100 rebounds, causing the rack portion 911 to slide into the second guide groove 412. Since the groove depth of the second guide groove 412 is shallow, the rack portion 911 is axially stopped, the transmission assembly 90 is locked in the low position, and the rubber plug 70 presses the end of the through hole portion 51 to form a continuous seal, which is equivalent to the locked state after the ballpoint pen refill is extended.

[0031] When the user presses the button 60 for the second time, the drive rod 61 slides down along the first guide groove 411 / second guide groove 412 via the guide member 611. Simultaneously, the serrated structure 612 of the drive rod 61 pushes the rack portion 911 of the rotating rod 91 down along the second guide groove 412. When the rotating rod 91 slides until the rack portion 911 disengages from the second guide groove 412, the first inclined surface 9111 at the end of the rack portion 911 aligns with the serrated surface 6121 of the end serrated structure 612 of the drive rod 61, forcing the rotating rod 91 to rotate a certain angle along the serrated surface 6121 of the serrated structure 612; thus causing the rack portion 91... The first inclined surface 9111 of 1 is aligned with the second inclined surface 4131 of the protrusion 413, and rotates to align with the first guide groove 411 under the continued guidance of the second inclined surface 4131 of the protrusion 413; after releasing, the reset elastic member 100 rebounds, causing the rack part 911 to slide into the first guide groove 411. Due to the deep groove of the first guide groove 411, the rack part 911 has a large upward space, the transmission component 90 is locked in a high position, the rubber plug 70 rises away from the through hole part 51 with the second connector, the ventilation channel is reopened, and the pressure inside and outside the can 10 is instantly balanced, which is equivalent to the retraction of the ballpoint pen refill.

[0032] Through this "two-step pressing" ballpoint pen-like action, the rubber stopper 70 only undergoes a slight displacement in the axial direction and is always constrained within the cap, eliminating the need for manual removal and achieving one-handed one-button sealing and unsealing.

[0033] As a preferred embodiment, the upper cover 40 is provided with at least two guide channels 42, which are equidistantly arranged in a ring around the axis of the connecting channel 41. The pressing member 60 includes guide rods 62, with each guide channel 42 corresponding to a guide rod 62, and the guide rods 62 are slidably connected in the guide channels 42. This arrangement creates at least two guide channels 42 equidistantly arranged in a ring around the axis of the connecting channel 41 on the same circumference of the upper cover 40. The pressing member 60 extends the same number of guide rods 62, each guide rod 62 inserted into its corresponding guide channel 42 and capable of sliding along its axial direction. When the user presses down, the guide rods 62 and the guide channels 42 form multi-point guide rail constraints, preventing the drive rod 61 from rotating or swaying laterally, thus evenly distributing the lateral force of the finger into a pure axial thrust. This structure ensures a smooth and uninterrupted pressing process. In this embodiment, two guide channels 42 are provided.

[0034] As a preferred embodiment of the above, the upper cover 40 is provided with a recessed movable cavity 43, and the pressing member 60 is movably connected to the movable cavity 43; and the inner wall of the movable cavity 43 is provided with at least two limiting grooves 431, which are equidistantly arranged in a ring around the axis of the connecting channel 41; the pressing member 60 is provided with limiting buckles 63, which correspond one-to-one with the limiting grooves 431, and the limiting buckles 63 are slidably connected to the limiting grooves 431. With this configuration, the top surface of the upper cover 40 is recessed inward to form the movable cavity 43, and the pressing member 60 is placed entirely within the movable cavity 43 and can slide up and down; the inner wall of the movable cavity 43 is provided with at least two limiting grooves 431 equidistantly arranged on the same circumference, and the same number of limiting buckles 63 extend from the outer periphery of the pressing member 60, with each limiting buckle 63 embedded in the corresponding limiting groove 431. During the pressing process, the limiting buckle 63 slides axially along the limiting groove 431, providing guidance for the pressing member 60 and preventing the fragrance buckle from coming out through the groove wall of the limiting groove 431, thereby preventing the pressing member 60 from popping out as a whole and detaching from the upper cover 40 under the elastic force of the reset elastic member 100. In this embodiment, four limiting grooves 431 are provided.

[0035] As a preferred embodiment of the above, the rubber stopper 70 has a second hollow structure 71 inside, and the open end of the second hollow structure 71 has a first mounting portion 72; the outer periphery of the second transmission member 93 has a concave first mounting groove 931, and the first mounting portion 72 is fitted into the first mounting groove 931; and the second hollow structure 71 has a spring-loaded gap 73 inside, which serves as a spring-loaded deformation space for the rubber stopper 70. With this configuration, the second hollow structure 71 inside the rubber stopper 70 provides it with elastic deformation capability in the axial direction; the first mounting portion 72 protrudes inward from the open end to engage with the concave first mounting groove 931 on the outer periphery of the second transmission member 93, thereby firmly fixing the rubber stopper 70 to the second transmission member 93 without the need for screws or glue. After the press-type transmission structure 80 completes the "press-rotate-lock" process, the reset elastic element 100 will generate a small rebound stroke. At this time, the rebound gap 73 inside the second hollow structure 71 allows the top of the rubber plug 70 to undergo a slight elastic compression, absorbing the rebound amount and ensuring that the end face of the rubber plug 70 is always in close contact with the end face of the through hole 51, avoiding instantaneous air leakage caused by the slight movement of the reset elastic element 100.

[0036] As a preferred embodiment, the end of the through hole 51 facing the rubber plug 70 is provided with a protruding bone portion 511, which is arranged in a ring shape. This arrangement, by having the bone portion 511 protrude outwards towards the rubber plug 70, effectively reduces the distance between the through hole 51 and the rubber plug 70, thereby ensuring that the rubber plug 70 can effectively seal the through hole 51.

[0037] As a preferred embodiment of the above, the sealing ring 30 is fixed to the outer periphery of the lower cover 50. Specifically, the lower cover 50 has a second mounting groove 52 with a concave structure arranged circumferentially on its outer periphery. The sealing ring 30 includes a second mounting portion 31 and a sealing portion 32. The second mounting portion 31 is used to fit into the second mounting groove 52, and the sealing portion 32 is used to fit against the inner wall of the tank 10. With this configuration, during assembly, the second mounting portion 31 of the sealing ring 30 is radially pressed into the second mounting groove 52 of the lower cover 50 to form a firm fitting connection without the need for glue or additional fasteners. The outer edge of the sealing ring 30 extends outward to form a flexible sealing portion 32. When the cover assembly 20 is snapped into the tank 10, the sealing portion 32 is radially compressed by the inner wall of the tank 10, generating a uniform circumferential sealing band to block the entry of outside air, thereby forming a closed space 11 between the tank 10 and the cover assembly 20.

[0038] As a preferred embodiment of the above, the upper cover 40 and the lower cover 50 are connected by a threaded connection, a snap-fit ​​connection, or an interference fit. This arrangement, by providing multiple detachable connection methods, enhances the flexibility of the connection between the upper cover 40 and the lower cover 50.

[0039] It should be noted that the other contents of the sealed storage tank disclosed in this utility model are existing technologies and will not be described in detail here.

[0040] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any application of this utility model directly or indirectly in other related technical fields is included within the patent protection scope of this utility model.
