Description

Technical Field

[0001] This application relates to a sealing cap, and more particularly to a vacuum sealing cap. Background Technology

[0002] Existing containers typically have vacuum devices on their lids, such as those used for pickling vegetables. However, the most common vacuuming method is manual press-type vacuuming. The principle is as follows: a vacuum chamber is set in the sealed lid, containing a pressing component, such as a pressure plate or piston. Repeated pressing changes the chamber's volume using the piston's movement. When pressed, the chamber volume decreases, expelling internal air; when released, the chamber volume returns to normal, and due to the one-way valve, air from inside the container enters the chamber. Repeating this process achieves a vacuum effect. However, this existing technology has the following drawbacks: the vacuuming volume is very low, and leaks are prone to occur. Utility Model Content

[0003] This application provides a vacuum sealing cap to solve the problems existing in related technologies. The technical solution is as follows:

[0006] The exhaust valve is located on the air extraction cover and at the exhaust port.

[0007] The air extraction component is located on the air extraction cover and is situated within a groove. When the air extraction component is pulled out, the exhaust valve moves along with the air extraction component to allow the gas to be discharged.

[0008] The air intake assembly has one part on the air extraction cover and the other part on the air extraction assembly. The part of the air intake assembly on the air extraction cover is located inside the cylindrical hole. When the air intake assembly is pressed, air enters through the air extraction cover.

[0009] In one implementation,

[0010] The air extraction assembly includes:

[0011] The button base is located on the air extraction cover and is situated within a recess.

[0012] A plastic upper cover is installed inside the air extraction cover, and the top of the button base passes through the plastic upper cover;

[0013] The first spring has its two ends respectively positioned between the plastic upper cover and the button base;

[0014] The first sealing ring is installed on the button base so that the button base fits against the vent cover. When the button base is pulled out, the vent valve is opened under the action of the first sealing ring.

[0035] Plastic handle, the plastic handle is set on the button base, the plastic handle has a hand buckle position.

[0036] The advantages or beneficial effects of the above technical solutions include at least the following:

[0037] By using a vacuum assembly in conjunction with an exhaust valve, when the vacuum assembly is pumping air, the exhaust valve opens under air pressure, allowing the gas inside the container to escape. When the vacuum assembly is released, the exhaust valve re-closes to the exhaust port under external air pressure, thus completing the extraction of air from the container. When the container needs to be opened, the intake assembly is pressed down to allow air to re-enter the container, thereby achieving both vacuuming and intake within the container. The vacuum assembly increases both the volume and efficiency of vacuuming, ensuring stable vacuuming.

[0049] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0050] Figures 1-3 A structural diagram of a vacuum sealing cap according to an embodiment of this application is shown. Figures 1-3 As shown, the sealing cap may include:

[0051] The air extraction cover 100 has a groove 110, a cylindrical hole 120 and an exhaust hole 130, and the exhaust hole 130 and the cylindrical hole 120 are connected to the groove 110.

[0052] Exhaust valve 200 is installed on the air extraction cover 100 and is located at exhaust port 130.

[0053] The air extraction assembly 300 is mounted on the air extraction cover 100 and is located in the groove 110. When the air extraction assembly 300 is pulled out, the exhaust valve 200 moves with the air extraction assembly 300 to allow the gas to be discharged.

[0054] The air intake assembly 400 has a portion disposed on the air extraction cover 100 and another portion disposed on the air extraction assembly 300. The portion of the air intake assembly 400 disposed on the air extraction cover 100 is located inside the cylindrical hole 120. When the air intake assembly 400 is pressed, the air extraction cover 100 takes in air.

[0055] In this embodiment, the exhaust cap 100 is screwed onto the container, the exhaust port 130 is connected to the cylindrical hole 120 and the inside of the container, the exhaust valve 200 is installed at the exhaust port 130, after installation, a part of the air intake component 400 is pre-installed at the cylindrical hole 120, and another part of the air intake component 400 is installed at the exhaust component 300, and finally the exhaust component 300 is installed in the groove 110;

[0056] When evacuation is required, the evacuation component 300 is pulled out, and the exhaust valve 200 moves with the pulling direction. The gas in the container can be discharged from the container to the outside under the action of the pressure difference. When the gas is discharged and the pressure in the container is lower than the outside pressure, the exhaust valve 200 will be attracted to the exhaust hole 130 by the outside pressure, thereby achieving the sealing of the container inside and outside and preventing outside air from entering.

[0057] When exhaust is required, press down the air intake assembly 400 so that the air intake assembly 400 is not in contact with the air extraction cover 100 and the air extraction assembly 300, so that air enters the container through the air extraction assembly 300 and the air extraction cover 100. After releasing the air intake assembly 400, the air intake assembly 400 returns to its original position.

[0058] By using the suction assembly 300 in conjunction with the exhaust valve 200, when the suction assembly 300 is evacuating air, the exhaust valve 200 is opened under the action of air pressure, thereby venting the gas inside the container. When the suction assembly 300 is released, the exhaust valve 200 is re-adhered to the exhaust port 130 under the action of external air pressure, thus completing the extraction of air from the container. When it is necessary to open the container, the air intake assembly 400 is pressed down to allow air to re-enter the container, thereby realizing the extraction and intake of air inside the container. The suction assembly 300 increases the suction volume and efficiency while ensuring stable suction.

[0059] like Figures 2-3 As shown, in one embodiment,

[0060] The air extraction assembly 300 includes:

[0061] Button base 310 is mounted on the air extraction cover 100 and is located in the groove 110;

[0062] A plastic upper cover 320 is installed inside the air extraction cover 100, and the top of the button base 310 passes through the plastic upper cover 320.

[0063] The first spring 330 has its two ends respectively disposed between the plastic upper cover 320 and the button base 310;

[0064] The first sealing ring 340 is disposed on the button base 310 so that the button base 310 fits against the vent cover 100. When the button base 310 is pulled out, the vent valve 200 is opened under the action of the first sealing ring 340.

[0065] In this embodiment, a first spring 330 is fitted on the outer side of the button base 310. After the first spring 330 is assembled with the button base 310, the overall assembly is completed by the top plastic pressure cover 320 to form a spring-loaded reset structure.

[0066] After each pull-out operation is completed, the elastic force of the first spring 330 can press the button base 310 down to the initial position at the bottom of the air extraction cover 100, so as to perform the next pull-out operation.

[0067] The air extraction assembly 300 also includes:

[0068] The elastic buckle 321 is set on the plastic upper cover 320. The plastic upper cover 320 is detachably set on the air extraction cover 100 through the elastic buckle 321. The air extraction cover 100 has positioning ribs that are adapted to the elastic buckle 321.

[0069] Specifically, at least two elastic clips 321 are provided, and the preferred number is four. After the button base 310 is installed inside the air extraction cover 100, the plastic upper pressure cover 320 is connected to the four corresponding elastic clips 321 of the button base 310 through its own four elastic clips 321. At the same time, the air extraction cover 100 is provided with positioning ribs on the top to ensure that the installation positions of the plastic upper pressure cover 320 and the button base 310 are accurately aligned.

[0070] like Figures 2-3 As shown, in one embodiment,

[0071] The keypad 310 has an inverted "T" shaped cross-section. The first sealing ring 340 is located at the bottom of the keypad 310. The keypad 310 has an annular groove that matches the first sealing ring 340. The keypad 310 also has several venting grooves, all of which are connected to the annular groove.

[0072] In this embodiment, the button base 310 has an inverted T-shaped cross-section. When the button base 310 is pulled, the first sealing ring 340 and the vent cover 100 move together, forming a piston. When the button base 310 draws air, the exhaust valve 200 is pulled up under the action of air pressure. Since the exhaust port 130 is connected to the inside of the container, air inside the container is drawn out. Four slots are reserved on the inner edge of the exhaust port 130. When the pulling operation is performed, the exhaust valve 200 moves with the pulling direction, and the gas inside the container can be discharged from the inside of the container through the slots under the action of air pressure difference.

[0073] The exhaust cover 100 also has several slots located at the exhaust port 130. When the button base 310 is pulled out, the exhaust valve 200 moves in the same direction as the button base 310, and the gas is discharged through the slots under the action of the pressure difference.

[0074] The top of the exhaust port 130 has a sealing surface. When the gas is discharged and the gas pressure is lower than the external gas pressure, the exhaust valve 200 is sealed on the sealing surface under the action of the external gas pressure.

[0075] The exhaust valve 200 is made of silicone. The top of the exhaust port 130 has a sealing surface. When the gas pressure inside the container is lower than the outside pressure after the gas is discharged, the exhaust valve 200 will be adsorbed onto the sealing surface by the outside pressure, thereby achieving a seal between the inside and outside of the container and preventing outside air from entering.

[0076] In addition, a sealing cap is installed at the corresponding position of the vent 130. The sealing cap is connected to the vent cap 100 by a tight fit, which can prevent objects inside the tank from blocking the vent 130.

[0077] like Figures 2-3 As shown, in one embodiment,

[0078] The intake assembly 400 includes:

[0079] The first plastic button 410 is disposed on the button base 310;

[0080] The second spring 420 is sleeved on the first plastic button 410, and the two ends of the second spring 420 are respectively disposed on the first plastic button 410 and the button base 310.

[0081] The second sealing ring 430 is disposed on the first plastic button 410. In the initial state, the second sealing ring 430 is in contact with the button base 310. When the first plastic button 410 is pressed, the second sealing ring 430 does not contact the button base 310, and gas is input through the gap between the first plastic button 410 and the button base 310.

[0082] The air intake assembly 400 also includes: a second plastic button 440, a third spring 450, and a third sealing ring 460. The structure of the second plastic button 440, the third spring 450, and the third sealing ring 460 is the same as that of the first plastic button 410, the second spring 420, and the second sealing ring 430. The second plastic button 440 is disposed on the air extraction cover 100 and passes through the cylindrical hole 120. When the first plastic button 410 is pressed, the second plastic button 440 moves with the first plastic button 410.

[0083] The second plastic button 440 and the third spring 450 are both located inside the cylindrical hole 120.

[0084] In this embodiment, the exhaust cover 100 has a cylindrical hole 120 inside for installing the second plastic button 440. A third spring 450 is first installed below the second plastic button 440, and then the whole assembly is inserted into the cylindrical hole 120. At the same time, a third sealing ring 460 is set on one end of the second plastic button 440 inside the cylindrical hole 120, forming a linkage structure of "press to exhaust air - release to spring back and seal". When pressed, air can be exhausted. After releasing, the third spring 450 drives the second plastic button 440 to reset, and the third sealing ring 460 re-seals.

[0085] Similarly, the first plastic button 410, the second spring 420, the second sealing ring 430, and the button base 310 operate on the same principle as above. The first plastic button 410 forms a sealed structure with the button base 310 through the second sealing ring 430. When the first plastic button 410 is pressed, the first plastic button 410 and the second plastic button 440 move simultaneously, thereby forming a double sealing structure to ensure airtightness.

[0086] When it is necessary to open the sealed container, press the first plastic button 410 at the center of the container lid. The first plastic button 410 compresses the second spring 420 below, which drives the sealing structure to move, causing the second sealing ring 430 and the third sealing ring 460 to disengage from the sealing position, thereby enabling airflow to connect the inside and outside of the container, and thus achieving air pressure balance, making it convenient to open the vent cover 100.

[0087] like Figures 2-3 As shown, in one embodiment, it further includes:

[0088] The cup lid sealing ring 140 and the vacuum cover 100 have a groove that fits the cup lid sealing ring 140. When the vacuum cover 100 is installed on the cup, the cup lid sealing ring 140 fits against the cup mouth.

[0089] In this embodiment, the inner side of the lower part of the vent cap 100 is provided with a groove for engaging the cup lid sealing ring 140. After the cup lid sealing ring 140 is engaged in the groove, it forms an interference fit with the vent cap 100. At the same time, the inner side wall of the lower part of the vent cap 100 is threaded, which can be connected to a container with matching threads on the outer wall by screwing. During this process, the cup lid sealing ring 140 can achieve a seal between the vent cap 100 and the top (mouth) of the container.

[0090] like Figures 2-3 As shown, in one embodiment, it further includes:

[0091] Decorative cover 500 is provided on the vent cover 100.

[0092] In this embodiment, the wooden decorative cover 500 is glued to the top of the exhaust cover 100. Positioning grooves are pre-made around the exhaust cover 100 to enhance the adhesion of the glue and ensure a firm connection between the wooden decorative cover 500 and the exhaust cover 100.

[0093] like Figures 2-3 As shown, in one embodiment, it further includes:

[0094] A plastic handle 600 is mounted on a button base 310 and has a handle position.

[0095] In this embodiment, two circular slots are provided on the upper side of the button base 310 for installing a semi-circular plastic handle 600 (the plastic handle 600 has a certain deformation capability). The two are connected by a spring buckle, which is convenient for disassembly and assembly and the connection is stable.

[0096] The semi-circular plastic handle 600 has a hand grip on the side. When air needs to be extracted, rotate the handle 90° and pull it upward to extract the air. After extraction, place the handle flat on top of the plastic upper cover 320. At this time, the overall height of the handle is lower than the top plane of the wooden decorative cover 500, which can meet the needs of stacking and storing multiple sealed containers.

[0097] The functions of each module in each device of this utility model embodiment can be found in the corresponding description in the above method, and will not be repeated here.
