[0011] According to an embodiment of the present invention, the operating member further comprises an operating portion connected to the at least one rotating portion and configured to drive the at least one rotating portion to rotate so as to switch the operating member between the first position and the second position.

[0012] According to an embodiment of the present invention, the at least one rotating portion is pivotally connected to a through hole structure or an axial structure of one of the covering portion of the valve member or the valve seat of the container.

[0013] According to an embodiment of the present invention, when the operating member is located at the second position, a connecting channel is formed between the valve member and the container, so that an audible sound is generated when air flows through the connecting channel.

[0014] In order to achieve the above object, the present invention discloses a container assembly. The container assembly includes a container and a control valve. The control valve includes a valve member and an operating member. The valve member is mounted on the container and can be elastically deformed. The operating member can be rotated and switched between a first position and a second position. When the operating member moves from the first position to the second position, the valve member is elastically deformed by the operating member, so that at least a portion of the valve member is separated from the container.

[0015] According to an embodiment of the present invention, the valve member includes an abutment portion and a cover portion. The abutment portion abuts against the first side surface of the container; the cover portion is connected to the abutment portion and can be elastically deformed by at least one of the second side surface of the container or the operating member.

[0016] According to one embodiment of the present invention, when the operating member is located at the first position, the covering portion does not undergo elastic deformation caused by the operating member; when the operating member is located at the second position, the covering portion undergoes elastic deformation caused by the operating member, so that at least a portion of it is separated from the second side of the container.

[0017] According to an embodiment of the present invention, when the operating member is located at the first position, the covering portion is attached to the second side surface of the container and is elastically deformed by the second side surface of the container.

[0018] According to an embodiment of the present invention, the operating member is pivotally connected to one of the valve member or the container.

[0019] According to one embodiment of the present invention, the operating member comprises at least one rotating portion and at least one driving portion. The at least one rotating portion is pivotally connected to one of the valve member or the container.

[0023] According to an embodiment of the present invention, when the operating member is located at the second position, a connecting channel is formed between the valve member and the container, so that an audible sound is generated when air flows through the connecting channel.

[0024] In summary, the control valve of the present invention can switch different states by moving the operating member to different positions to promote or limit the balance between the internal air pressure and the external air pressure of the container. Therefore, the present invention has the characteristic of being easy to operate. In addition, for example, when the operating member is located at the second position, an audible sound is generated when the air flow passes through the connecting channel formed between the valve member and the container until the internal air pressure of the container reaches a balance with the external air pressure. Therefore, the user can easily identify whether the internal air pressure of the container and the external air pressure are balanced by the audible sound.

[0039] See also Figures 1 to 3 . Figure 1 and Figure 2 It is a schematic diagram of the container assembly 1 in different states in the first embodiment of the present invention. Figure 3 FIG. 1 is an exploded view of the container assembly 1 in the first embodiment of the present invention. Figures 1 to 3 As shown, the container assembly 1 includes a container 11 and a control valve 12 disposed on the container 11. In this embodiment, the container 11 is a hard box. In addition, when the control valve 12 is in a state as shown in FIG. Figure 1 In the first state shown in FIG. 1 , the control valve 12 is configured to allow only air flow from the interior of the container 11 to the external environment, so as to set the interior of the container 11 to a vacuum. Figure 2 In the second state shown, the control valve 12 is further configured to allow airflow from the interior of the container 11 to flow to the external environment and from the external environment to flow into the interior of the container 11, so as to set the interior of the container 11 to a non-vacuum state.

[0040] However, the present invention is not limited to this embodiment. For example, in another embodiment, the container may be a soft bag. Alternatively, in another embodiment, when the control valve is in a first state, the control valve may be configured to only allow airflow from the external environment to flow into the interior of the container to pressurize the interior of the container; when the control valve is in a second state, the control valve is further configured to allow airflow from the external environment to flow into the interior of the container, and to allow airflow from the interior of the container to flow to the external environment to depressurize the interior of the container.

[0041] like Figures 1 to 3As shown in FIG. 1 , the control valve 12 includes a valve member 121 and an operating member 122. The valve member 121 is installed on the container 11 and can be elastically deformed. The operating member 122 can be Figure 1 The first position P1 and Figure 2 The control valve 12 is rotated and switched between the second position P2 shown in FIG. Figure 1 The first state shown and Figure 2 Switches between the second states shown.

[0042] Please refer to Figures 4 to 9 . Figure 4 and Figure 5 1 is a partial view of the container assembly 1 at different viewing angles when the operating member 122 is located at the first position P1 in the first embodiment of the present invention. Figure 6 4 is a partial cross-sectional view of the container assembly 1 when the operating member 122 is located at the first position P1 in the first embodiment of the present invention. Figure 7 and Figure 8 1 is a partial view of the container assembly 1 at different viewing angles when the operating member 122 is located at the second position P2 in the first embodiment of the present invention. Fig. 9 FIG. 1 is a partial cross-sectional view of the container assembly 1 when the operating member 122 is located at the second position P2 in the first embodiment of the present invention. Figures 4 to 6 As shown, when the operating member 122 is located at the first position P1, that is, the control valve 12 is in the first state, the valve member 121 does not undergo elastic deformation caused by the operating member 122, so that the valve member 121 is connected to the container 11 and undergoes elastic deformation caused by the container 11, so that the air flow is only allowed to flow from the inside of the container 11 to the external environment, so as to limit the balance between the internal air pressure of the container 11 and the external air pressure. Figures 7 to 9 As shown, when the operating member 122 moves from the first position P1 to the second position P2 to switch the control valve 12 from the first state to the second state, the valve member 121 is elastically deformed due to the operating member 122, causing at least a portion of the valve 121 to be separated from the container 11, thereby forming a connecting channel C between the valve member 121 and the container 11 to allow airflow from the external environment inside the container 11 to flow to the external environment, and airflow from the external environment to flow into the interior of the container 11, so that the internal air pressure and the external air pressure of the container 11 are balanced.

[0043] Further, if Figures 4 to 9As shown, the valve member 121 is arranged on the opening O formed on the valve seat 111 of the container 11, and the valve member 121 includes a contact portion 1211 and a cover portion 1212. The contact portion 1211 is contacted with the first side surface S1 of the container 11. The cover portion 1212 is connected to the contact portion 1211 and is configured to be elastically deformed by at least one of the second side surface S2 of the container 11 and the operating member 122. In this embodiment, the first side surface S1 and the second side surface S2 of the container 11 are respectively located on the inner side and the outer side of the container 11, that is, the contact portion 1211 and the cover portion 1212 of the valve member 121 are respectively located on the inner side and the outer side of the container 11.

[0044] Preferably, the valve member 121 may be an integrated structure, that is, the abutting portion 1211 and the cover 1212 are integrally connected, and the valve member 121 may be made of an elastomeric material.

[0045] like Figures 4 to 6 As shown, when the operating member 122 is located at the first position P1, the contact portion 1211 contacts the first side surface S1 of the container 11, and provides a first force along the first direction D1 to the covering portion 1212, so that the covering portion 1212 is attached to the second side surface S2 of the container 11 and undergoes elastic deformation, and when the operating member 122 is located at the first position P1, the covering portion 1212 does not undergo elastic deformation caused by the operating member 122. Since when the operating member 122 is located at the first position P1, under the action of the airflow flowing from the inside of the container 11 to the external environment, at least a portion of the covering portion 1212 can be forced to separate from the second side surface S2 of the container 11, so that when the operating member 122 is located at the first position P1, the covering portion 1212 allows the airflow to flow from the inside of the container 11 to the external environment. Because when the operating member 122 is located at the first position P1, under the action of the airflow flowing from the external environment into the interior of the container 11, the covering portion 1212 can be forced to adhere to the second side surface S2 of the container 11, so that when the operating member 122 is located at the first position P1, the covering portion 1212 can block the airflow flowing from the external environment into the interior of the container 11.

[0046] like Figures 7 to 9As shown, when the operating member 122 is located at the second position P2, the operating member 122 is configured to provide a second force to the covering portion 1212 along a second direction D2 opposite to the first direction D1, so that the covering portion 1212 undergoes elastic deformation due to the operating member 122, and at least a portion is separated from the second side surface S2 of the container 11, thereby allowing airflow to flow from the interior of the container 11 to the external environment, and allowing airflow to flow from the external environment into the interior of the container 11, so that the internal air pressure of the container 11 is balanced with the external air pressure.

[0047] In addition, if Figures 4 to 9 As shown, in this embodiment, the operating member 122 is pivotally connected to the valve member 121. However, the present invention is not limited to this embodiment. For example, in another embodiment, the operating member can be pivotally connected to the container.

[0048] Specifically, the operating member 122 includes a rotating portion 1221, two driving portions 1222 and an operating portion 1223. The rotating portion 1221 is pivotally connected to the valve member 121. The two driving portions 1222 protrude from both ends of the rotating portion 1221, respectively, and when the operating member 122 is rotated from the first position P1 to the second position P2, the two driving portions 1222 are connected to the container 11. The operating portion 1223 is connected to the rotating portion 1221, and is configured to drive the rotating portion 1221 to rotate, so that the operating member 122 rotates between the first position P1 and the second position P2. However, the number and structure of the rotating portion and the driving portion are not limited to this embodiment. For example, in another embodiment, the operating member may include a driving portion located only at one end of the rotating portion. Alternatively, in another embodiment, the operating member may include two rotating portions arranged coaxially and two driving portions located at two ends of the two rotating portions, respectively.

[0049] Preferably, in order to realize the pivot connection between the valve member 121 and the rotating portion 1221 of the operating member 122, a through hole 1213 is provided on the valve member 121. The through hole 1213 can be integrally connected with the covering portion 1212 and is close to the second side surface S2 of the container 11. The rotating portion 1221 is provided as a circular shaft structure, which can rotatably pass through the through hole structure 1213 to be pivotally connected with the through hole 1213 and is close to the second side surface S2 of the container 11. However, the present invention is not limited to this embodiment. For example, in another embodiment, the rotating portion can be provided as a hook-shaped structure, which can be rotatably engaged with the shaft-shaped structure provided on the valve member.

[0050] Preferably, each driving part 1222 is configured in a cam shape. When the operating part 122 is located at the first position P1, the two driving parts 1222 do not abut against the second side surface S2 of the container 11; when the operating part 122 is located at the second position P2, the two driving parts 1222 abut against the second side surface S2 of the container 11. In the process of the operating part 122 moving from the first position P1 to the second position P2, the operating part 122 moves away from the second side surface S2 of the container 11 along the second direction D2, and the abutment between the two driving parts 1222 and the second side surface S2 of the container 11 provides a second force along the second direction D2 to the covering part 1212 of the valve part 121, so that the covering part 1212 of the valve part 121 undergoes elastic deformation caused by the operating part 122 and along the second direction D2, and at least a part of the covering part 1212 is separated from the second side surface S2 of the container 11.

[0051] Preferably, the operating member 122 abuts against a blocking portion 1214 provided on the valve member 121 , and the blocking portion 1214 may be integrally connected with the covering portion 1212 to restrict the operating member 122 at the first position P1 when the operating member 122 is located at the first position P1 .

[0052] It is worth noting that when the operating member 122 moves from the first position P1 to the second position P2 to set the interior of the container 11 to non-vacuum, airflow can flow from the external environment into the interior of the container 11 through the connecting channel C between the valve member 121 and the container 11 to balance the internal air pressure of the container 11 with the external air pressure. For example, during the process of balancing the internal air pressure of the container 11 with the external air pressure, the operating member 122 can be kept at the second position P2 by the friction between the two driving parts 1222 and the second side surface S2 of the container 11, so that the connecting channel C maintains a small size, and thus the airflow passing through the connecting channel C between the valve member 121 and the container 11 can produce an audible sound until the internal air pressure of the container 11 is balanced with the external air pressure, or the pressure difference between the internal air pressure of the container 11 and the external air pressure is greatly reduced to zero. Therefore, in this embodiment, when the interior of the container 11 is set to be non-vacuum, the user can easily identify whether the internal air pressure of the container 11 is balanced with the external air pressure by listening to the audible sound.

[0053] Please refer to Figures 10 to 18 . Fig.10 and Fig.11 Schematic diagram of a container assembly 1' in different states in the second embodiment of the present invention. Fig.12It is an exploded view of the container assembly 1' in the second embodiment of the present invention. Fig.13 and Fig.14 1 is a cross-sectional view of the container assembly 1 ′ along different section lines when the operating member 122 ′ is located at the first position P1 in the second embodiment of the present invention. Fig.15 1 is a partial view of the container assembly 1 ′ in the second embodiment of the present invention, when the valve member 121 ′ has not undergone elastic deformation due to the operation member 122 ′ being located at the first position P1 . Fig.16 and Fig.17 1 is a cross-sectional view of the container assembly 1 ′ along different section lines when the operating member 122 ′ is located at the second position P2 in the second embodiment of the present invention. Fig.18 FIG. 1 is a partial view of the container assembly 1' in the second embodiment of the present invention, when the valve member 121' undergoes elastic deformation due to the operation member 122' being located at the second position P2'. Figures 10 to 12 As shown, the container assembly 1' comprises a container 11' and a control valve 12'. Different from the first embodiment, in this embodiment, the container 11' is a soft bag. In addition, the control valve 12' is configured to be Fig.10 In the first state shown, only air flow from the external environment is allowed to flow into the interior of the container 11' to pressurize the interior of the container 11', and the control valve 12' is further configured to be in a state where the control valve 12' is in the state shown in FIG. Fig.11 In the second state shown, air flow is allowed to flow from the external environment into the interior of the container 11 ', and from the interior of the container 11 ' to the external environment, so as to reduce the pressure inside the container 11 '.

[0054] In addition, if Figures 12 to 18 As shown, in this embodiment, the first side surface S1' and the second side surface S2' of the container 11' are respectively the outer side and the inner side of the container 11', that is, the abutting portion 1211' and the covering portion 12112' of the valve body 121' are respectively close to the outer side and the inner side of the container 11' through the opening portion O' located on the valve seat 111' of the container 11'.

[0055] In addition, if Figures 12 to 18 As shown, in this embodiment, the operating member 122 ′ is pivotally connected to the valve seat 111 ′ of the container 11 ′.

[0056] Specifically, in this embodiment, the operating member 122' includes two rotating parts 1221', two driving parts 1222' and an operating part 1223' connected to the two rotating parts 1221'. The two rotating parts 1221' of the operating member 122' are coaxially arranged and pivotally connected to the valve seat 111' of the container 11'. The two driving parts 1222' protrude from the two rotating parts 1221' respectively, and when the operating member 122' moves from the first position P1' to the second position P2', the two driving parts 1222' abut against the covering part 1212' of the valve member 121'.

[0057] Preferably, in this embodiment, two shaft portions 1112' are provided on the valve seat 111' of the container 11', and each rotating portion 1221' is provided with a hook-shaped structure pivotally connected to the corresponding shaft portion 1112'.

[0058] Preferably, in this embodiment, two through grooves 1113' are provided on the valve seat 111' of the container 11', providing the two driving parts 1222' with a passage for contacting the covering part 1212' of the valve member 121' close to the second side surface S2' of the container 11'. In addition, the two through grooves 1113' are covered by the covering part 1212' of the valve member 121', so as to prevent the airflow from flowing from the interior of the container 11 to the external environment through any one of the two through grooves 1113' when the operating member 122' is located at the first position P1.

[0059] Preferably, in this embodiment, when the operating member 122 ′ is located at the first position P1 ′, the operating member 122 ′ abuts against the valve seat 111 ′, so as to restrict the operating member 122 ′ to the first position P1 ′.

[0060] However, the present invention is not limited to this embodiment. For example, in another embodiment, only one shaft portion and one through groove are provided on the valve seat of the container, and the operating member may include a rotating portion pivotally connected to the shaft portion and a driving portion protruding from the rotating portion. Alternatively, in another embodiment, the rotating portion may be provided as a round shaft structure, and the round shaft structure may rotatably pass through a through hole structure formed on the valve seat.

[0061] like Fig.10 , Figures 13 to 15 As shown, in this embodiment, when the operating member 122' is located at the first position P1', each driving portion 1222' does not abut against the covering portion 1212' of the valve member 121'. Fig.11 , Figures 16 to 18As shown, when the operating member 122' is located at the second position P2', each driving component 1222' abuts against the covering portion 1212' of the valve member 121'.

[0062] In addition, if Fig.10 , Figures 13 to 15 As shown, when the operating member 122' is located at the first position P1', the abutting portion 1211' abutting against the first side surface S1' of the container 11' provides the covering portion 1212' with a third force along the second direction D2, so as to drive the covering portion 1212' to adhere to the second side surface S2' of the container 11' and undergo elastic deformation, and when the operating member 122' is located at the first position P1', the covering portion 1212' does not undergo elastic deformation caused by the operating member 122'. When the operating member 122' is located at the first position P1', due to the airflow flowing from the inside of the container 11' to the external environment, the covering portion 1212' can be forced to adhere to the second side surface S2' of the container 11', so the covering portion 1212' of the operating member 122' blocks the airflow from the inside of the container 11' to the external environment. When the operating member 122' is located at the first position P1', due to the airflow flowing from the external environment into the interior of the container 11', at least a portion of the covering portion 1212' can be forced to separate from the second side surface S2' of the container 11'. Therefore, when the operating member 122' is located at the first position P1', the covering portion 1212' allows airflow from the external environment to flow into the interior of the container 11'.

[0063] like Figures 13 to 18As shown, when the operating member 122' moves from the first position P1' to the second position P2' to reduce the pressure inside the container 11', the operating member 122' provides a fourth force along the first direction D1 to the covering portion 1212' of the valve member 121' through the abutment between the two driving parts 1222' and the covering portion 1212', so that the covering portion 1212' of the valve member 121' undergoes elastic deformation along the first direction D1 caused by the operating member 122', so that at least a portion of it is separated from the second side surface S2' of the container 11', forming a connecting channel C' between the valve member 121' and the container 11', so as to guide the airflow from the interior of the container 11' to the external environment, thereby balancing the internal air pressure of the container 11' and the external air pressure. For example, during the process of balancing the internal air pressure of the container 11' with the external air pressure, the friction between the two driving parts 1222' and the covering part 1212' keeps the operating member 122' at the second position P2', so that the connecting channel C' is kept at a smaller size, so that the airflow from the inside of the container 11' through the connecting channel C' into the external environment can produce an audible sound until the internal air pressure of the container 11' is balanced with the external air pressure, or the pressure difference between the internal air pressure of the container 11' and the external air pressure is greatly reduced to zero. Therefore, in this embodiment, the user can easily identify whether the internal air pressure of the container 11' is balanced with the external air pressure by listening to the audible sound.

[0064] The other details of this embodiment are the same as those of the first embodiment, and for the sake of simplicity, detailed description is omitted herein.

[0065] Compared with the prior art, the control valve of the present invention switches between different states by operating the operating member to different positions to promote or limit the balance between the internal air pressure of the container and the external air pressure. Therefore, the present invention has the characteristic of being easy to operate. In addition, for example, when the operating member is located at the second position, the airflow generates the audible sound when passing through the connecting channel formed between the valve member and the container until the internal air pressure of the container and the external air pressure are balanced. Therefore, the user can easily identify whether the internal air pressure of the container is balanced with the external air pressure through the audible sound.

[0066] For those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. Therefore, the above embodiments only express several implementation methods of the present invention, but cannot be understood as limiting the scope of the invention patent.
