Description

Technical Field

[0001] The utility model belongs to the field of storage boxes, and in particular relates to a vacuum cover and a vacuum storage container. Background Art

[0002] The handle flip storage box is a storage container with a simple appearance and good sealing effect. It is widely used to store items that require high preservation requirements such as dryness and leakage prevention. Its working principle is to place the box lid on the opening of the box body, and make the sealing seat on the lower side of the box lid extend into the box cavity of the box body, then flip the handle on the box lid and drive the sealing seat to move upward through the handle so that the sealing ring on the outer periphery of the sealing seat expands outward under the interference of the box lid and fits tightly against the inner circumferential wall of the box body, so that the box lid seals the box cavity in the box body. In this state, the box lid facing upward will cause the box cavity to increase in volume and reduce in pressure, thereby limiting the box lid from escaping upward from the box body under the external atmospheric pressure to ensure the stability of the connection. If the box lid needs to be opened, first flip the handle to make the sealing seat move downward so that the sealing ring can be reset without interference from the box lid to release the abutment against the inner circumferential wall of the box body, so that the box cavity is connected to the outside world and the box lid can be driven to separate from the box body upward.

[0003] The disadvantage of the existing handle flip storage box is that after the handle is flipped to seal the box cavity, the pressure in the box cavity is close to the atmospheric pressure, so the connection strength between the box body and the box cover is limited, and the box body and the box cover are easily separated by force after a certain pulling force is applied.

It should be noted that the following are only some specific embodiments of the concept of the present utility model and only a part of the embodiments of the present utility model. The specific and direct descriptions of the relevant structures are only for the convenience of understanding the present utility model, and each specific feature does not of course and directly limit the scope of implementation of the present utility model. Conventional selections and substitutions made by those skilled in the art under the guidance of the concept of the present utility model shall be regarded as being within the scope of protection required by the present utility model.

[0046] Embodiment 1:

[0047] As Figures 1 - 13 shown, the present utility model discloses a vacuum-pumping type cover body for cooperating with a container 6 to cover and vacuum-seal the container 6, including:

[0048] A cover base 1, the cover base 1 is provided with two vertically penetrating through-sliding holes 11;

[0049] A sealing base 2, the sealing base 2 is located below the cover base 1, and two penetrating-sliding parts 21 are arranged on the upper side of the sealing base 2, so that the sealing base 2 is vertically slidably arranged on the cover base 1 through the penetrating-sliding cooperation between the penetrating-sliding parts 21 and the through-sliding holes 11. In addition, a sealing ring 3 is arranged on the outer periphery of the sealing base 2, and the sealing ring 3 expands outward from bottom to top, so that the lower end of the sealing ring 3 is set as an installation part 31 to fixedly install the sealing ring 3 on the sealing base 2 by means of a pressing ring 26, and the upper end of the sealing ring 3 is set as a sealing part 32, and the sealing part 32 further expands outward by the lower edge of the cover base 1 when sliding upward with the sealing base 2 to act on the inner peripheral wall of the container 6 to be cooperated with to achieve extrusion sealing. A cooperation clamping groove 22 is arranged on one side of the two penetrating-sliding parts 21 facing away from each other;

[0050] A handle 4, the handle 4 is U-shaped, and cooperation clamping protrusions 41 are protrudingly arranged on the opposite sides of the two ends of the U-shape of the handle 4, so that the handle 4 can be relatively flipped through the clamping connection between the cooperation clamping protrusions 41 and the cooperation clamping groove 22. In addition, a first positioning surface 42 is arranged on both sides of the handle 4, a second positioning surface 43 is arranged at both ends of the handle 4 and is coplanar, and the distance from the first positioning surface 42 to the central axis of the cooperation clamping protrusion 41 is s1, and the distance from the second positioning surface 43 to the central axis of the cooperation clamping protrusion 41 is s2, s1 > s2. So that when the first positioning surface 42 is flipped to abut against the cover base 1, the distance between the central axis of the cooperation clamping protrusion 41 and the cover base 1 is s1 and is larger, thereby lifting the sealing base 2 upward. When the second positioning surface 43 is flipped to abut against the cover base 1, the distance between the central axis of the cooperation clamping protrusion 41 and the cover base 1 is s2 and is smaller, thereby lowering the sealing base 2 downward, so that the handle 4 can control the lifting and lowering of the sealing base 2 by flipping;

[0051] The air extraction seat 5 can be fixedly arranged on the cover seat 1, or fixedly arranged on the sealing seat 2, or movably arranged between the cover seat 1 and the sealing seat 2, and is clamped and fixed when the cover seat 1 and the sealing seat 2 approach each other.

[0052] Therefore, in Figure 6 In the state shown, the cover body faces downwards so that the cover seat 1 is placed above the container 6, and the sealing seat 2 is inserted into the container 6. Then, by flipping the handle 4 forward, the handle 4 changes from abutting against the cover seat 1 on the second positioning surface 43 to abutting against the cover seat 1 on the first positioning surface 42. Thus, under the action of the mating convex 41 and the mating card slot 22, the sealing seat 2 is lifted upwards, so that under the action of the cover seat 1 expanding the outer diameter of the sealing ring 3, the sealing portion 32 is squeezed and fitted against the inner peripheral wall of the container 6 to make the inside of the container 6 in a sealed state, that is, to form Figure 5 the state shown, and then in Figure 8 In the state shown, an air extraction device (the air extraction device shown in this embodiment is an air extraction cylinder 7) is used in cooperation with the air extraction seat 5 to extract the air inside the container 6 to reduce the pressure inside the container 6. Thus, the external air pressure is much greater than the pressure inside the container 6, so that the external pressure acts on the cover body and the container 6 to realize a high-strength connection between the two.

[0053] Among them, when the first positioning surface 42 is flipped to abut against the cover seat 1 to form Figure 5 the first state shown, and when the second positioning surface 43 is flipped to abut against the cover seat 1 to form Figure 6 the second state shown. In the first state, the U-shaped handle 4 is flipped to fit against the cover seat 1, making the overall structure more compact, and the handle 4 is not easily flipped by external interference, so as to effectively ensure the sealing stability inside the container 6. In the second state, the handle 4 is perpendicular to the cover seat 1, so that the user can separate the cover body and the container 6 by holding the handle 4 and lifting it upwards.

[0054] Preferably, an inner groove 12 that is recessed downwards is provided on the upper side of the cover seat 1 in this embodiment; in the first state, the handle 4 is located inside the inner groove 12, and in the second state, a part of the handle 4 extends out of the inner groove 12.

[0055] Therefore, through the inner groove 12, the handle 4 is built-in in the first state to further prevent the handle 4 from being flipped by external interference, so as to effectively ensure the sealing stability inside the container 6. And in the second state, a part of the handle 4 extends out, so that it is convenient for the user to hold and lift through the extended part of the handle 4.

[0056] Among them, an air extraction head 51 is provided on the air extraction seat 5 in this embodiment, and an air extraction area 14 is provided above the air extraction head 51 on the cover seat 1, and an external air extraction device is connected to the air extraction area 14 and the air extraction head 51.

[0057] Preferably, the air extraction head 51 is located within the inner groove 12, such that the inner groove 12 protects the air extraction head 51.

[0058] Preferably, the air extraction head 51 is located between the U-shaped handles 4. In the first state, the handle 4 and the air extraction area 14 are misaligned; in the second state, the handle 4 and the air extraction area 14 are arranged in an all or partial overlapping manner.

[0059] Therefore, in the first state, the handle 4 fits against the cover base 1, rendering the air extraction area 14 above the air extraction head 51 interference-free. An external air extraction device can then be placed in the air extraction area 14 and cooperate with the air extraction head 51 to extract air from the interior of the container 6. In the second state, the portion of the handle 4 perpendicular to the cover base 1 enters the air extraction area 14, preventing the external air extraction device from being placed in the air extraction area 14 and thus preventing air extraction, serving as an anti-fool operation indication.

[0060] Preferably, a pressure relief hole 23 is vertically penetrated through the sealing seat 2 in this embodiment, and a plug member 13 protruding downward is integrally formed at the lower end of the cover base 1. When the sealing seat 2 slides downward relative to the cover base 1, the plug member 13 is disengaged downward from the pressure relief hole 23 to open the pressure relief hole 23. When the sealing seat 2 slides upward relative to the cover base 1, the plug member 13 is inserted upward into the pressure relief hole 23 to block the pressure relief hole 23.

[0061] Therefore, with the cooperation of the pressure relief hole 23 and the plug member 13, it is possible to more effectively achieve the communication between the interior of the container 6 and the outside world in the second state to achieve internal and external constant pressure, making it easier to remove the cover body from the container 6. This prevents the sealing portion 32 from sticking to the inner peripheral wall of the container 6 due to the cover body not being disassembled from the container 6 for a long time, or in cases where the sealing ring 3 is too large in size and the sealing portion 32 always fits against the inner peripheral wall of the container 6, ensuring that the interior of the container 6 remains sealed in the second state and guaranteeing smooth opening.

[0062] Among them, in this embodiment, the air extraction seat 5 is made of an integrally formed rubber member. In addition to the above-mentioned air extraction head 51, the air extraction seat 5 further includes a sealing clamping ring 52 extending outward below the air extraction head 51 and a plugging portion 53 extending inward above the air extraction head 51.

[0063] Specifically, the sealing clamping ring 52 is located between the cover base 1 and the sealing seat 2. In the first state, the mutually approaching cover base 1 and sealing seat 2 clamp the sealing clamping ring 52 to achieve fixation and circumferential sealing. In the second state, there is a relatively large gap between the mutually separated cover base 1 and sealing seat 2, allowing the sealing clamping ring 52 to move within a certain range in this gap.

[0064] Specifically, a first air extraction hole 24 penetrating vertically is provided on the sealing seat 2, and a first air extraction opening 25 is formed at the lower end of the first air extraction hole 24. A second air extraction hole 531 is provided on the blocking portion 53, and a second air extraction opening 532 is formed at one end of the second air extraction hole 531. Thus, during the air extraction process, since the pressure in the container 6 is greater than the pressure in the air extraction cylinder 7, the air pressure acts on the blocking portion 53 to make it face upward, causing the blocking portion 53 to separate from the sealing seat 2. Then, the first air extraction opening 25 and the second air extraction opening can be connected to extract the gas in the container 6. After the air extraction is completed, since the pressure in the container 6 is less than the pressure of the external air, the air pressure acts on the blocking portion 53 to make it face downward, causing the blocking portion 53 to fit against the sealing seat 2 to block the first air extraction hole 24. Thus, the first air extraction opening 25 and the second air extraction opening are disconnected, and the container 6 is in a sealed state.

[0065] In other embodiments, the air extraction seat 5 can also be made of other elastic injection-molded parts, such as silicone parts.

[0066] Preferably, the first air extraction hole 24 in this embodiment is conical in shape, and the outer peripheral shape of the blocking portion 53 is adapted to the shape of the first air extraction hole 24 so that the outer peripheral wall of the blocking portion 53 fits against the inner peripheral wall of the first air extraction hole 24, enabling the blocking portion 53 to have a larger area to cooperate with the first air extraction hole 24 and improve the effectiveness of sealing.

[0067] Preferably, the second air extraction opening is provided on the outer peripheral wall of the blocking portion 53, making the overall structure more compact, and the second air extraction opening can be set to a larger volume to improve the air extraction efficiency.

[0068] In addition, a lifting portion 54 is provided protruding upward on the blocking portion 53 in this embodiment. The lifting portion 54 is used to be lifted to connect the first air extraction opening 25 and the second air extraction opening.

[0069] Therefore, in the first state and when the inside of the container 6 is in a low-pressure state, first, lift the lifting portion 54 to connect the inside of the container 6 with the outside to equalize the pressure to near the external pressure, and there is a prompt sound for pressure equalization. After releasing the lifting of the lifting portion 54, the lifting portion 54 resets, and the blocking portion 53 continues to block the first air extraction hole 24. At this time, the inside of the container 6 is still in a sealed state. Then, when the handle 4 is flipped, since the pressures inside and outside the container 6 are close, during the flipping process of the handle 4, the sealing seat 2 will not be subjected to an excessive downward reset movement trend due to the external atmospheric pressure, and the flipping of the handle 4 can be more controllable, resulting in a higher user experience. On the contrary, directly flipping the handle 4 in a low-pressure state will cause the atmospheric pressure to have a great downward driving force on the sealing seat 2. When the sealing seat 2 moves downward rapidly, it will synchronously drive the handle 4 to flip rapidly, presenting a danger of the handle 4 uncontrollably bouncing back and affecting the user experience.

[0070] In other embodiments, the handle 4 can be hinged to the cover base 1 and connected to the sealing seat 2 through an eccentric structure to realize the flipping of the handle 4 relative to the cover base 1 and the lifting of the sealing seat 2. In addition, the lifting of the sealing seat 2 achieved by the relative flipping of other handles 4 should all fall within the protection scope.
