Description

Technical Field

[0001] This utility model relates to the field of sealed containers, and in particular to a manually sealed cap and a sealed container. Background Technology

[0002] Existing airtight containers are designed to prevent the contents from becoming damp or spoiling through sealing. Typical airtight containers rely on a tight seal between the bottle and cap to achieve a tight seal. For scenarios requiring even better sealing, vacuum-sealed containers have emerged. These containers, after being sealed with a cap, maintain a negative pressure state by evacuating the gas inside. Existing manual vacuum-sealed caps integrate a pressure-evacuation component, allowing manual pressure to create a vacuum inside the container. This method requires particularly high sealing performance from the cap itself, especially the pressure-evacuation component. Due to its mobility, it's crucial to ensure both smooth operation and a tight seal; otherwise, leakage will occur, affecting the effectiveness of the vacuuming process. Utility Model Content

[0003] The purpose of this invention is to provide a manual sealing cap that improves the structure of the cap, resulting in better sealing performance, which helps to improve the efficiency of air extraction and maintain a sealed state.

[0004] To achieve the above objectives, the present invention adopts the following solution: A manually sealed cover includes an outer cover and an inner cover connected to each other, wherein the outer cover is provided with a press-to-evacuate assembly and a pressure relief assembly; The outer cover covers the outer periphery of the inner cover, and the outer cover has a first inner cavity with an opening facing downwards. The press-to-suction assembly extends from the first inner cavity to the upper side of the outer cover. The upper end of the inner cover is provided with a second inner cavity with the opening facing upward. The second inner cavity is provided with an air extraction channel opposite to the pressing air extraction component. The air extraction channel is provided with an air extraction hole, and the air extraction hole is provided with a one-way valve. The press-to-exhaust assembly can reciprocate relative to the outer cover and the exhaust channel, and the press-to-exhaust assembly is also provided with an elastic connector on its outer periphery. The other end of the elastic connector is fixed in the second inner cavity and surrounds the outer periphery of the exhaust channel.

[0005] As described above, in a manual sealing cover, the lower end of the elastic connector is provided with a downwardly extending first retaining edge, and the second inner cavity is provided with an annular retaining groove into which the first retaining edge extends.

[0006] As described above, in a manual sealing cover, the first inner cavity is provided with a downwardly extending pressing part, which is opposite to the annular groove.

[0007] As described above, in a manual sealing cover, the press-to-evacuate assembly includes an inner movable member and a housing sleeved around the outer periphery of the inner movable member, and the upper end of the elastic connector is further provided with a second retaining edge extending between the inner movable member and the housing.

[0008] As described above, in a manual sealing cover, the inner movable part is sleeved on the outer periphery of the air extraction channel, and the inner movable part is provided with an air guide hole, and the air guide hole is provided with a second one-way valve.

[0009] As described above, in a manual sealing cover, the outer periphery of the inner movable member is further provided with a retaining ring extending radially outward. The second retaining edge includes a transverse sealing portion extending laterally and a vertical sealing portion extending vertically. The transverse sealing portion abuts against the upper side of the retaining ring, and the vertical sealing portion is located in the gap between the inner movable member and the outer shell. The lower side of the outer shell is a pressing plane pressing against the upper side of the transverse sealing portion.

[0010] As described above, a manual sealing cover has a pressure relief hole on both the outer cover and the inner cover. The pressure relief assembly includes a pressure relief button extending from the pressure relief hole of the outer cover and a sealing part located at the pressure relief hole of the inner cover. The sealing part is installed below the pressure relief button.

[0011] As described above, in a manual sealing cover, the outer cover covers the outer periphery of the inner cover, and a snap fastener is provided between the inner side of the outer cover and the outer periphery of the inner cover.

[0012] This utility model also provides a sealing container, including a bottle body, on which the above-mentioned manual sealing cap is installed.

[0013] In summary, the advantages of this utility model over the prior art are: This utility model provides a manual sealing cover, which adds an elastic connector to the outside of the movable press-to-suction component and the suction channel. The elastic connector separates the space between the outer periphery of the channel and the inner cavity, so that the outer periphery of the channel is surrounded and sealed by the elastic connector. This does not affect the movement of the press-to-suction component, but also forms a good sealing effect, thereby ensuring the efficiency of suction and the problem of air leakage of the cover itself.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a manual sealing cover, including an outer cover 1 and an inner cover 2 connected to each other. The outer cover 1 is provided with a press-to-extract air assembly 3 and a pressure relief assembly 4. When in use, the sealing cover is used to extract air by repeatedly pressing the air extraction assembly 3, thereby creating a negative pressure state inside the tank.

[0018] In this design, the cover is a split type. The outer cover 1 covers the outer periphery of the inner cover 2. The outer cover 1 has a first inner cavity 101 with its opening facing downwards. The press-to-extract assembly 3 extends from the first inner cavity 101 to the upper side of the outer cover 1. The upper end of the inner cover 2 has a second inner cavity 201 with its opening facing upwards. The second inner cavity 201 has an air extraction channel 200 opposite to the press-to-extract assembly 3. The air extraction channel 200 has an air extraction hole 2001, and the air extraction hole 2001 has a one-way valve 2002. The press-to-extract assembly 3 can reciprocate relative to the outer cover 1 and the air extraction channel 200. The press-to-extract assembly 3 also has an elastic connector 5 on its outer periphery. The other end of the elastic connector 5 is fixed in the second inner cavity 201 and surrounds the outer periphery of the air extraction channel 200. This utility model provides a manual sealing cover, which adds an elastic connector to the outside of the movable press-to-suction component and the suction channel. The elastic connector separates the space between the outer periphery of the channel and the inner cavity, so that the outer periphery of the channel is surrounded and sealed by the elastic connector. This does not affect the movement of the press-to-suction component, but also forms a good sealing effect, thereby ensuring the efficiency of suction and the problem of air leakage of the cover itself.

[0019] In this design, the one-way valve is preferably a one-way rubber stopper. It allows for one-way airflow, thus preventing external gas from entering during evacuation and achieving a good seal on the evacuation port. The rubber stopper's main material properties are good elasticity and corrosion resistance, allowing it to fit tightly against the evacuation port. Furthermore, it is low in cost and replaceable.

[0020] In this solution, the elastic connector 5 can be made of silicone or rubber materials with good elasticity. It not only provides a sealing effect, but its elasticity also helps to press the vacuum assembly 3 to reset.

[0021] Specifically, in this embodiment of the present invention, the lower end of the elastic connector 5 is provided with a downwardly extending first retaining edge 51, and the second inner cavity 201 is provided with an annular retaining groove into which the first retaining edge 51 extends. Furthermore, the press-to-vacuum assembly 3 includes an inner movable member 31 and a outer shell 32 sleeved around the outer periphery of the inner movable member 31. The upper end of the elastic connector 5 is also provided with a second retaining edge 52 extending between the inner movable member 31 and the outer shell 32. This is equivalent to the lower end of the elastic connector 5 being engaged in the second inner cavity 201, and the upper end being engaged in the press-to-vacuum assembly 3, so that the upper end can reciprocate with the press-to-vacuum assembly 3, while the lower end remains stationary, maintaining a relatively sealed state in the enclosed space. This ensures good airtightness without affecting the movement of the press-to-vacuum assembly 3, resulting in better vacuuming efficiency and preventing internal air leakage after vacuuming.

[0022] Furthermore, the first inner cavity 101 of this solution is provided with a downwardly extending pressing part 1011, which is opposite to the annular groove. After the outer cover 1 and the inner cover 2 are installed, the pressing part 1011 presses the first retaining edge 51 into the annular groove, thereby improving the sealing effect after installation.

[0023] In this embodiment of the present invention, the inner movable member 31 is sleeved on the outer periphery of the air extraction channel 200, and the inner movable member 31 is provided with an air guide hole, and the air guide hole is provided with a second one-way valve 2003.

[0024] In addition, in this solution, the outer periphery of the inner movable member 31 is provided with a retaining ring 310 extending radially outward. The retaining ring 310 can also serve as a limiting device for installing springs. A spring can be added between the lower side of the retaining ring 310 and the second inner cavity to facilitate the reset of the inner movable member 31.

[0025] Of course, the retaining ring 310 also enhances the sealing effect. The second retaining edge 52 includes a transverse sealing portion 521 extending laterally and a vertical sealing portion 522 extending vertically. The transverse sealing portion 521 abuts against the upper side of the retaining ring 310, and the vertical sealing portion 522 is located in the gap between the inner movable member 31 and the outer shell 32. The lower side of the outer shell 32 is a pressing plane that presses against the upper side of the transverse sealing portion 521. The cross-section of the second retaining edge 52 is L-shaped, which matches the L-shaped gap between the outer shell 32 and the inner movable member 31 to form a suitable shape, achieving a good sealing effect. Moreover, the lower side of the outer shell 32 is a pressing plane, which can better press the sealing portion during operation, thereby preventing air leakage.

[0026] Specifically, the outer cover 1 and the inner cover 2 are provided with through pressure relief holes. The pressure relief assembly 4 includes a pressure relief button 41 extending from the pressure relief hole of the outer cover 1 and a sealing part 42 located at the pressure relief hole of the inner cover 2. The sealing part 42 is installed below the pressure relief button 41. When it is necessary to open the cover, the internal pressure of the tank is restored by first releasing the pressure. In this solution, only the pressure relief button 41 needs to be pressed to open the lower sealing part 42.

[0027] Of course, in order to make the cover body more aesthetically pleasing, the lower part of the inner cover body 2 is also provided with a retaining sleeve 8, which covers the lower side of the sealing part 42.

[0028] In this solution, the outer cover 1 covers the outer periphery of the inner cover 2, and a buckle is provided between the inner side of the outer cover 1 and the outer periphery of the inner cover 2.

[0029] like Figure 6 As shown, this utility model also provides a sealed container, including a bottle body, on which the above-mentioned manual sealing cap is installed.

[0030] This utility model provides a manual sealing cover, which adds an elastic connector to the outside of the movable press-to-suction component and the suction channel. The elastic connector separates the space between the outer periphery of the channel and the inner cavity, so that the outer periphery of the channel is surrounded and sealed by the elastic connector. This does not affect the movement of the press-to-suction component, but also forms a good sealing effect, thereby ensuring the efficiency of suction and the problem of air leakage of the cover itself.

[0031] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification 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 the claimed utility model.
