Description

Drink container with straw Field of invention

The present invention relates to a beverage container with a straw attached to a straw for inhaling a beverage.

Background of the invention

It is heretofore known that a drink container with a straw attached to a child is assumed to be a user. A straw cap is provided in the beverage container, and the straw cap can conceal the straw in a bent state to close the straw exposed to the outside when not in use. If the straw cap is opened during use, the occlusion of the straw can be released, so that the user can use the straw to drink the beverage that has been filled into the container.

However, when a hot drink such as hot water having a temperature higher than that of the outside atmosphere is placed in the container, the internal pressure of the closed container is increased. Therefore, if the straw cover is opened, the beverage is ejected from the straw which is released from the closure simultaneously with the opening. The situation. Therefore, an on-off valve for releasing the internal pressure to the outside is generally provided in the beverage container with the straw attached.

For example, a beverage container with a straw attached to such an on-off valve is known as a beverage container in which a locking member that holds the straw cap in a closed state and an on-off valve that has been disposed in the air hole of the container. When the valve system is integrated and the lock of the suction cap is released by the operation of the lock member, the air hole is opened by the valve body, whereby the internal pressure can be released (Patent Document 1).

[Patent Document 1] Japanese Patent Laid-Open Publication No. 2002-321741

The beverage container of Patent Document 1 can release the internal pressure by the operation of the locking member that releases the locking of the straw cap, however, once the air hole that has been opened is to be closed, the locking member must be operated again with the straw cap open. That is, after the straw cap is opened to constitute a drinkable beverage, the user is forced to perform the operation of the locking member for closing the air hole, and therefore, the operation of the locking member becomes annoying to the user. Further, when the user forgets the operation of the locking member which should be performed after opening the straw cap, since the air hole is still opened, there is a possibility that the beverage leaks from the air hole, for example, when the beverage container is used obliquely.

Further, in the beverage container of Patent Document 1, after the internal pressure is released by the release of the suction cap, the air hole can be closed by operating the lock member again in a state where the suction cap is opened. However, in the case where the outside temperature is high in the summer, if the air hole is closed and placed in the state in which the straw cover is opened, there is a problem that the beverage leaks from the straw due to the expansion of the air in the container. In order to avoid such a problem, in the beverage container of Patent Document 1, it is necessary to operate the locking member to open the air hole while opening the suction tube cover. Further, thereafter, when the straw cap is closed and the application is to be stopped, the locking member must be operated again to perform the operation of closing the air hole. Accordingly, when the beverage container of Patent Document 1 is used without causing leakage of the beverage, the operation of the locking member becomes annoying to the user.

Accordingly, it is an object of the present invention to provide a beverage container with a straw that prevents the user from being bored with the operation.

A beverage container according to a first aspect of the present invention, comprising: a container body having an opening; and a pipette joint installed in the container body to block the opening; and for sucking into the container body The straw of the beverage is installed in the straw joint, and further includes a straw cover attached to the straw joint in a state in which the closed position of the straw is hidden and the open position in which the straw is exposed; The locking member is operable between the locking position of the straw cap locked in the closed position and the releasing position for releasing the locking; the opening and closing valve is configured to block the closed state of the inside and outside of the container body and communicate with the container body Changing the state between the open state of the inside and the outside, and changing from the closed state to the open state by accepting the predetermined operation, and returning to the closed state from the open state by releasing the predetermined operation; and transmitting the member Actuating the locking member from the locked position toward the release position as before the opening and closing valve The predetermined operation is performed, and the inlet valve is separated from the opening and closing valve in a state in which the suction pipe cover is in the open position to release the predetermined operator of the opening and closing valve.

According to the beverage container, the on-off valve is changed from the closed state to the open state by the action of the locking member from the locking position to the release position, and the predetermined operation is released in a state where the suction tube cover is in the open position, and therefore, the on-off valve system is self-opening. The state is restored to the off state. Therefore, the internal pressure can be released by releasing the locking of the straw cap, and the opening and closing valve automatically forms a closed state after opening the straw cap. Therefore, the user does not need to be particularly deliberate and can be released when the straw cap is opened. Pressing, again, after opening the straw cap, the beverage can be prevented from leaking through the switching valve even if the operation of the locking member is not performed. Accordingly, it is possible to prevent the user from being bored with the necessary operations when using.

The structure or material of the on-off valve is not particularly limited. For example, the on-off valve may have a valve body, and the valve body may be elastically deformed by the aforementioned communication member as a push operation as the predetermined operation, and is made of an elastic material. Further, the valve system is converted into the open state by elastic deformation using the pushing operation, and is restored to the closed state from the open state by the elimination of the elastic deformation by the release of the pushing operation. According to this aspect, even if the on-off valve is not formed by a plurality of components, the open state and the closed state can be changed by the elastic deformation of the valve body made of an elastic material, so that the number of parts can be easily reduced.

In this aspect, the valve body can integrate the plate portion dividing the inside and the outside of the container body with the cylindrical holding portion that can receive the pushing operation while maintaining the periphery of the plate portion, and form a slit in the plate portion. The slit extends in the same direction as the operation direction of the above-described pushing operation, and penetrates in the plate thickness direction. At this time, in a state where no external force is applied to the valve body, the slit is closed, whereby the valve body is maintained in the closed state. When the holding portion of the valve body is pushed in, the plate portion is deformed in accordance with the pushing operation. By the deformation of the plate portion, the distance between the ends of the slit is shortened, so that the slit opens and changes from the closed state to the open state. When such a pushing operation is released, the elastic deformation of the valve body is eliminated, and both the plate portion and the holding portion return to the original state, so that the slit is closed and can be restored to the closed state.

The shape of the plate portion is arbitrary. For example, the plate portion may be formed in a curved shape that protrudes toward the inner side of the container body. At this time, when the pressure at the pressure on the inner side of the container body is higher than the atmospheric pressure by the plate portion as a boundary, the force for deforming the plate portion in the direction in which the slit is in close contact acts on the valve body. Therefore, when a pressure difference between the internal pressure and the atmospheric pressure is generated, the passage of the fluid in the outward direction from the inside of the container body is prevented, so that if the valve body is kept in the closed state, the beverage can be surely prevented from the container body toward the outside. leakage. On the other hand, when the pressure at the inner side of the container body is lower than the atmospheric pressure by the plate portion, that is, when the internal pressure constitutes a negative pressure, the force for deforming the plate portion in the direction of opening the slit is Act on the valve body. Therefore, when a pressure difference of the internal pressure lower than the atmospheric pressure is generated, the passage of the fluid in the direction from the outside of the container to the inside of the container can be allowed, and therefore, the amount of the beverage in the container body is reduced in accordance with the inhalation of the beverage using the straw. Although the internal pressure may constitute a negative pressure, at this time, if the magnitude of the negative pressure is larger than the limit of the opening slit, the external atmosphere is also taken into the container body through the valve body. Therefore, since the user who uses the straw to inhale the beverage is not required to have a great suction force, the burden on the user can be reduced.

When the valve body is made of an elastic material, the suction pipe may have a suction port formed of the same material as the valve body, and the suction port portion may be integrated with the valve body. At this time, when the straw cap is closed, the mouthpiece portion can be easily elastically deformed, and since the mouthpiece portion is integrated with the valve body, the number of parts can be reduced.

In one aspect of the first beverage container of the present invention, the straw cap is detachably attachable to the straw joint through a support shaft and is rotatable, thereby being operable between the closed position and the open position, the locking member The straw cover is provided in a state in which the lock position is movable between the lock position and the release position, and the communication member is provided in the lock member in a state of being movable integrally with the lock member. According to this aspect, after the locking member is moved from the locking position to the releasing position, the straw cap is moved from the closed position to the open position, whereby the locking member and the conveying member are moved together with the straw cover in a direction away from the suction joint. . Therefore, even if a special device is not provided to move the communication member away from the on-off valve, the communication member can be easily moved away from the on-off valve by the action of the suction cap from the closed position toward the open position.

A beverage container according to a second aspect of the present invention, comprising: a container body having an opening; and a pipette joint installed in the container body to block the opening; and for sucking into the container body The straw of the beverage is installed in the straw joint, and further includes a straw cover attached to the straw joint in a state in which the closed position of the straw is hidden and the open position in which the straw is exposed; The on-off valve has a valve body, and the valve body can be elastically deformed during the pushing operation and is composed of an elastic material. Further, the valve system self-latching the inside and outside of the container body by elastic deformation using the aforementioned pushing operation. The closed state is changed to open between the inside and the outside of the container body, and is restored to the closed state from the open state by the elimination of the elastic deformation by the release of the pushing operation; the engaging portion is formed with the valve The body is adjacent to the straw joint or the straw cover; and the operating member is displaceable between the first state and the second state And the first state is that the suction pipe cover is engaged with the engagement portion in a state where the suction pipe cover is located at the open position, thereby performing the pushing operation on the valve body, and the second state is based on the opening of the suction pipe cover When the position is moved toward the closed position, the suction cap is brought into contact with the engagement portion, and the engagement with the engagement portion is released, whereby the push-in operator can be released.

According to the beverage container, since the valve system is made of an elastic material, even if the switching valve is not formed by a plurality of components, the open state and the closed state can be changed by elastic deformation of the valve body, so that the parts can be easily cut. number. Further, according to the beverage container, by the engagement of the operation member with the engagement portion in a state where the suction tube cover is in the open position, the operation member can apply the push operation to the valve body. Therefore, as long as the operating member is engaged with the engaging portion, the valve body is maintained in the open state. Therefore, even when the outside temperature rises while the straw cover is opened, it can be constantly released by connecting the inside and outside of the container body. The pressure is therefore prevented from leaking out of the beverage through the straw. Further, when the straw cap is operated from the open position to the closed position, the engagement of the operating member with the engaging portion is released during the operation thereof, and the pushing operation of the valve body is released, so that the valve body is automatically restored. Disabled. Therefore, it is possible to reliably prevent the straw cap from being in the closed position when the valve body is still open. Therefore, even if the user does not particularly deliberate, the straw lid can be prevented from leaking through the valve body during transportation or the like. Accordingly, since the user's operation opportunity is required to be reduced as compared with the past, it is possible to prevent the user from being bored with the operation.

The structure or material of the operating member is not particularly limited. For example, the operating member may be formed of the same material as the valve body, and the valve body may be integrated with the operating member. At this time, since the valve body and the operating member can be easily formed by a single process, and the number of parts can be reduced, the number of assembly steps can be reduced.

In one aspect of the second beverage container of the present invention, a protruding portion that protrudes upward from the container body and that can be easily pulled up by a user can be formed on the operating member, and the operating member is pulled by the protruding portion. And the engaging member is engaged with the engaging portion, wherein the operating member is engaged with the engaging portion, and the protruding portion is in contact with the straw during the operation of the straw cover from the open position to the closed position. The cover is pressed and pressed, whereby the engagement between the operating member and the engaging portion is released. According to this aspect, in order to engage the operating member with the engaging portion, the protruding portion that can be easily pulled up by the user has the function of releasing the engagement between the operating member and the engaging portion when the suction cap is closed. Therefore, it is possible to reduce the number of parts compared to separately preparing such a structure that can realize each function.

In one aspect of the second beverage container of the present invention, the valve body can integrate the plate portion dividing the inside and the outside of the container body with the cylindrical holding portion that can receive the pushing operation while receiving the periphery of the plate portion, and The plate portion forms a slit which extends in the same direction as the operation direction of the pushing operation and penetrates in the thickness direction. At this time, in a state where no external force is applied to the valve body, the slit is closed, whereby the valve body is maintained in the closed state. When the holding portion of the valve body is pushed in, the plate portion is deformed in accordance with the pushing operation. By the deformation of the plate portion, the distance between the ends of the slit is shortened, so that the slit opens and changes from the closed state to the open state. When such a pushing operation is released, the elastic deformation of the valve body is eliminated, and both the plate portion and the holding portion return to the original state, so that the slit is closed and can be restored to the closed state.

Form for implementing the invention

Fig. 1 is a partial side sectional view showing a beverage container with a straw attached to an embodiment of the present invention, and Fig. 2 is a plan view showing the beverage container shown in Fig. 1. As shown in the figures, a beverage container (hereinafter referred to as a beverage container) 1 with a straw includes a container body 2 having an opening 2a and capable of holding a drink, and a straw joint 3 which is configured to block the opening. 2a is installed in the container body 2. In order to allow the user to easily hold the beverage container 1, the handle H of a predetermined shape is integrally formed in the container body 2. An external thread 4 is provided on the outer peripheral portion of the upper portion of the container body 2, and an internal thread 5 that engages with the external thread 4 is provided on the inner peripheral portion of the straw joint 3. The straw joint 3 can be attached to the container body 2 by screwing the respective thread 4 and the thread 5 into the container body 2 in a state of being engaged with each other. A straw 6 is attached to the straw fitting 3 for sucking the beverage which has been placed in the container body 2. The straw 6 is configured by connecting the mouthpiece portion 7 and the body portion 8 to each other, and the mouthpiece portion 7 is flexible and can be held by a user, and the body portion 8 is housed in the container body 2. The mouthpiece portion 7 and the body portion 8 are formed of different kinds of materials, and the mouthpiece portion 7 is formed of a polyoxygen resin which is easily elastically deformed, and the body portion 8 connected thereto is formed of plastic.

The straw cap 9 is attached to the straw joint 3 in a state in which the closed position of the hidden straw 6 (see FIG. 1) and the open position at which the straw 6 is exposed (see FIG. 7) are operated. The straw cap 9 is attached to the straw joint 3 through the support shaft 10 and is rotatable, thereby being movable between a closed position and an open position. The suction tube cover 9 is provided with a protrusion portion 11 for blocking the suction tube 6 in a bent state in the closed position to be closed, and the protrusion portion 11 protrudes toward the lower side of the beverage container 1 . The straw 6 can be blocked when the straw cover 9 is in the closed position.

In order to make the straw cover 9 lockable in the closed position, the beverage container 1 is provided with a locking mechanism 15. The lock mechanism 15 includes a lock member 16 attached to the straw cover 9 in a state in which it can be operated between a lock position (first and second figures) and a release position (figure 5A, 5B), and the lock position is attached to Closing the position-locking straw cover 9, the releasing position is releasing the locking member; the restraining portion 17 is for engaging the locking member 16 with the straw fitting 3 when the locking member 16 is in the locking position (Fig. 2); The spring 18 imparts potential to the locking member 16 toward the locked position side.

The lock member 16 is slidable in the horizontal direction (toward the left-right direction of FIG. 1) from the lock position to the release position. The lock member 16 is partially exposed from the opening portion 9a formed on the upper surface of the straw cover 9, and an operation portion 19 that can be operated by a user is formed in the exposed portion. The restraining portion 17 is configured to have a groove shape extending in the same direction as the operation direction of the lock member 16, and the length of the groove has a length that the lock member 16 and the straw can be released when the lock member 16 reaches the release position. Engagement of the joint 3 (refer to Figure 5A). The return spring 18 is constructed of polyoxyn resin. If the locking member 16 is operated by the user to the release position and released, the locking member 16 can be restored to the locked position by the elastic force of the return spring 18.

In order to make it possible to release the internal pressure to the outside, the beverage container 1 is provided with an on-off valve 20 which is changeable between a closed state inside and outside the closed container body 2 and an open state between the inside and the outside of the container body 2. The on-off valve 20 includes a valve body 21, and the valve body 21 is composed of an elastically deformable elastic material. The valve body 21 is attached to the suction pipe joint 3 in a state in which the through hole 22 formed in the suction pipe joint 3 is in close contact with each other. In the beverage container 1, the valve body 21 is made of the same material as the suction port portion 7 of the suction pipe 6. The resin is configured to be integral with the mouthpiece portion 7. Since the beverage container 1 is integrated with the valve body 21, the number of parts can be reduced.

3A and 3B are enlarged views showing a state in which the valve body 21 is viewed from above, and Fig. 3A shows its closed state, and Fig. 3B shows its open state. As shown in the figures, the valve body 21 includes a plate portion 25 for dividing the inside and outside of the container body 2, and a holding portion 26 for holding the periphery of the plate portion 25 and having a tubular shape; A slit 27 penetrating in the thickness direction is formed. In the case of Fig. 3A, since the external force is not applied to the valve body 21, the slit 27 is closed in the close contact state, so that it can be maintained in the closed state. As shown in Fig. 3B, when the holding portion 26 of the valve body 21 is subjected to the pushing operation of the predetermined operation in the direction of the arrow mark, the plate portion 25 is elastically deformed in accordance with the pushing operation. The slit 27 extends in the operation direction of the pushing operation. Therefore, by the elastic deformation of the plate portion 25, the distance X between the ends of the slit 27 is shorter than the closed state of the third drawing, so that the slit is as shown in the figure. 27 will open and change from off state to on state. When the pushing operation is released, the elastic deformation of the valve body 21 is eliminated, and both the plate portion 25 and the holding portion 26 are returned to the original state, so that the slit 27 is closed and can be restored to the closing of the 3A drawing. status.

In order to contact the operation of the valve body 21 of the on-off valve 20 and the operation of the lock member 16 of the lock mechanism 15, as shown in Fig. 1, the beverage container 1 is provided with a communication member 30, which will be The on-off valve 20 transmits the action of the lock member 16 from the lock position to the release position as a push-in operation for the on-off valve 20. The communication member 30 is disposed integrally with the locking member 21, that is, the communication member 30 is movable integrally with the locking member 16.

4A to 6 are views showing the operation of each portion of the beverage container 1 in which the lock member 16 is operated from the state of Figs. 1 and 2 to the release position side to the side where the straw cover 9 is opened to the open position side. 4A and 4B are views showing a state during the start of the engagement of the lock member 16 to the engagement of the unlocking member 16 and the restraining portion 17, and FIG. 4A is a plan view of the state, and FIG. 4B is a side cross-sectional view of the state. . 5A and 5B show a state in which the unlocking member 16 and the restraining portion 17 are engaged, and FIG. 5A is a plan view of the state, and FIG. 5B is a side cross-sectional view of the state. Fig. 6 is a side sectional view showing a state in which the straw cover 9 is opened to the open position side.

In the state of Figs. 1 and 2 in which the operation of the lock member 16 is not performed, the communication member 30 is separated from the on-off valve 20 (valve body 21), and the valve body 21 is closed, and the straw cover 9 is closed. The position and the straw 6 are occluded, so that the container body 2 is sealed. As shown in FIGS. 4A and 4B, the operation of the lock member 16 is started from this state, and the lock member 16 is slightly moved toward the release position side, whereby the communication member 30 hits the holding portion 26 of the valve body 21 and starts the valve. The elastic deformation of the body 21. That is, the transfer member 30 starts the pressing operation of the valve body 21 and starts to open the slit 27. Therefore, the air in the container body 2 starts to flow in the direction of the arrow mark through the valve body 21, and starts to reduce the inside of the beverage container 1. Pressure.

Next, as shown in FIGS. 5A and 5B, when the lock member 16 is moved to the release position, the engagement between the lock member 16 and the restraint portion 17 is released, and the lock of the straw cover 9 is released. At the same time, the valve body 21 is further pushed in by the communication member 30, and the deformation of the valve body 21 constitutes the maximum result, and the opening condition of the slit 27 is also maximized, whereby the suction pipe 6 is locked. The internal pressure of the beverage container 1 is completely released. As shown in Figs. 5A and 5B, the restriction of the straw cap 9 is released while the lock member 16 is maintained in the release position, so that the straw cover 9 can be moved from the closed position toward the open position side.

As shown in Fig. 6, as the straw cap 9 is moved toward the open position side, the communication member 30 that moves together with the straw cover 9 is separated from the valve body 21, so that the valve body 21 can be released by the communication member 30. Push in operation. By the release of the pushing operation, the elastic deformation of the valve body 21 is eliminated, and the original state is returned (refer to Fig. 3A), and the valve body 21 is automatically restored to the closed state. Further, by the operation of the straw cap 9 toward the opening position side, the closing of the straw 6 by the straw lid 9 is released, and the mouthpiece portion 7 of the straw 6 is formed to extend straight, and the straw 6 can be used.

According to this, when the beverage container 1 is used, the user can surely release the internal pressure during the process of releasing the lock of the straw cover 9 and opening the straw cover 9 toward the open position side. Further, in the stage in which the suction pipe cover 9 is opened to constitute the usable suction pipe 6, the on-off valve 20 is automatically returned to the closed state, so that the user does not need to perform a special operation on the on-off valve 20 deliberately, and the beverage can be prevented from being used. Since the on-off valve 20 leaks out, it is possible to prevent the user from being bored with the necessary operations during use. Further, the beverage container 1 is provided to the lock member 16 in a state in which the communication member 30 is movable integrally with the lock member 16 provided on the straw cover 9, and therefore, even if a special device is not provided so that the valve body 21 is being pushed in The communicating member 30 of the operation leaves the switching valve 20 (the valve body 21), and the communication member 30 can be easily moved away from the switching valve 20 by the action of the suction cap 9 from the closed position toward the open position.

Unlike the case of a plurality of components, the on-off valve 20 of the beverage container 1 can be changed in an open state and a closed state by elastic deformation of a single valve body 21 made of an elastic material, so that the number of parts can be easily reduced. In addition, the on-off valve 20 also has the further features described below.

As shown in FIGS. 1 and 6 and the like, the on-off valve 20 is formed in a curved shape in which the plate portion 25 of the valve body 21 is convex toward the inner side of the container body 2, and more specifically, a spherical shape. When the plate portion 25 is a boundary and the pressure difference between the pressure on the inner side of the container body 2 is higher than the atmospheric pressure, the force that deforms the plate portion 25 in the direction in which the slit 27 is in close contact acts on the valve body 21. Therefore, when such a pressure difference is generated, the passage of the fluid from the inside of the container body 2 in the outward direction is prevented, so that if the valve body 21 is kept in the closed state, the beverage can be surely prevented from leaking from the container body 2 to the outside. . On the other hand, when the pressure difference on the inner side of the container body 2 is lower than the atmospheric pressure by the plate portion 25, that is, when the internal pressure constitutes a negative pressure, the plate portion 25 is deformed in the direction of opening the slit 27. The force acts on the valve body 21. Therefore, when such a pressure difference is generated, the passage of the fluid from the outside toward the inside of the container body 2 can be allowed, and therefore, the amount of the beverage in the container body 2 is reduced in accordance with the inhalation of the beverage by the straw 6. Although the internal pressure may constitute a negative pressure, at this time, if the magnitude of the negative pressure is larger than the limit of the opening slit 27, the outside atmosphere is also taken into the container body 2 through the valve body 21. Therefore, since the user who uses the straw 6 to inhale the beverage is not required to have a great suction force, the burden on the user can be alleviated.

In order to prevent the beverage from leaking out of the suction pipe 6 in the case where the outside temperature is high in the summer, the beverage container 1 is provided with an open state holding mechanism 40 which is in a state in which the suction pipe cover 9 is in the open position, so that the on-off valve is opened. 20 remains on. 7 to 9 are explanatory views for explaining the function of the open state holding mechanism 40, and Fig. 7 is a partial side sectional view showing the state in which the open state holding mechanism 40 releases the holding of the switching valve 20 in the open state, 8 is a partial side sectional view showing a state in which the opening state holding mechanism 40 holds the opening state of the switching valve 20, and FIG. 9 shows a state in which the suction pipe cover 9 is operated from the state shown in FIG. 8 to the closed position. Partial side section view.

As shown in FIG. 7, the closed state holding mechanism 40 includes an engaging portion 41 which is provided in the suction pipe joint 3, and an operating member 42 which can be engaged and disengaged by the engaging portion 41, The execution of the pushing operation of the valve body 21 and its release are switched. The engaging portion 41 is provided adjacent to the valve body 21 and configured to protrude toward the valve body 21 side. The operation member 42 is formed to protrude in a direction opposite to the engagement portion 41 and is fixed to the outer circumference of the holding portion 26. The operating member 42 is constructed of the same elastic material as the valve body 21, and is provided integrally with the valve body 21. Since the valve body 21 and the operation member 42 are integrated, the valve body 21 and the operation member 42 can be easily formed by a single process, and the number of parts can be reduced, so that the assembly man-hour can be reduced. Further, the operation member 42 is formed with an abutting portion 42a that protrudes above the container body 2 and can abut against the straw cover 9 as a protruding portion.

In a state where the straw cap 9 is in the open position, if the user moves the cylindrical holding portion 26 to the left of the same figure in the upper left end portion of Fig. 7, the operating member 42 is lifted upward by its elasticity. The operating member 42 hits the engaging portion 41 and is engaged with the engaging portion 41 (Fig. 8). Since the base end portion of the operation member 42 is fixed to the outer circumference of the holding portion 26, when the operation member 42 is lifted upward, the holding portion 26 is deformed and inclined. That is, the operation member 42 is engaged with the engagement portion 41, whereby the push operation is applied to the valve body 21, and the operation is maintained. The state of Fig. 8 corresponds to the first state of the present invention. As can be understood from Fig. 8, the pushing operation is applied in reverse to the operation of the above-described communication member 30, however, even by the pushing operation using the operating member 42, the slit 27 is extended toward the operation direction. Therefore, as in the case shown in Fig. 3B, the slit 27 is opened, and the valve body 21 is configured to be in an open state. As long as the operating member 42 is engaged with the engaging portion 41, the valve body 21 is maintained in the open state. Therefore, even when the outside temperature rises while the straw cover 9 is opened, the container body 2 can be connected to the inside and outside of the container body 2 The internal pressure is constantly released, so that the beverage can be prevented from leaking through the straw 6.

When the valve body 21 is still maintained in the open state, the straw cover 9 is moved from the open position to the closed position. As shown in FIG. 9, the abutting portion 42a formed on the operating member 42 is in contact with the straw cover 9, and is operated. Member 42 will be pressed down. Thereby, since the engagement of the operation member 42 and the engagement portion 41 is released, the pushing operation by the operation member 42 can be released. The state of Fig. 9 corresponds to the second state of the present invention. By the release of the pushing operation, the elastic deformation of the valve body 21 is eliminated, and the valve body 21 is returned to the original state. Therefore, the valve body 21 is returned from the open state to the closed state, and the beverage container 1 is sealed. That is, it is possible to surely prevent the straw cap 9 from forming the closed position when the valve body 21 is still open.

Since the beverage container 1 has the open state holding mechanism 40, even after the valve body 21 is opened, even if the user does not particularly deliberate, the straw cover 9 can be closed, and the beverage can be prevented from being passed through the valve body 21 during transportation or the like. And leaked out. Accordingly, in the beverage container 1, since the operation opportunity of the user is required to be reduced as compared with the past, it is possible to prevent the user from being bored with the operation. Further, the engaging portion 41 of the open state holding mechanism 40 is provided to the straw joint 3, but the engaging portion 41 may be provided to the straw cover 9. In other words, when the engagement portion 41 is provided in the suction tube cover 9 and is formed at the same position as that of the seventh embodiment, the suction tube cover 9 is moved toward the closed position side in a state where the operation member 42 hits the engagement portion 41. Thereby, the engaging portion 41 is rotationally moved downward, so that the engagement between the operating member 42 and the engaging portion 41 can be released.

Further, by operating the lock member 16C to the release position, the restriction of the straw cap 9C can be released, so that the straw cover 9C can be moved to the open position side. In a state where the straw cap 9C is in the open position, the lock member 16C is returned to the original position by the return spring 18C, and therefore, the communication member 30C is separated from the on-off valve 20, whereby the communication member 30C can be released. The valve body 21 of the switching valve 20 performs the pushing operation, and therefore, the switching valve 20 can be automatically restored to the closed state from the open state.

Fig. 13 is an explanatory view showing a fourth modification in a mode, in which the state viewed from above is displayed. The beverage container 1D according to the fourth modification is provided with a lock mechanism 15D for locking the straw cover 9D, and the rotation axis direction of the lock member 16D included in the lock mechanism 15D is different from that of the second modification and the third modification. In other words, the lock member 16D is set to the up-down direction of the beverage container 1D, and is attached to the straw joint 3D in a state in which it can be rotated from the illustrated lock position to the release position.

Further, by operating the lock member 16D to the release position, the restriction of the straw cap 9D can be released, so that the straw cap 9D can be moved to the open position side. In a state where the straw cap 9D is in the open position, the lock member 16D is returned to the illustrated position by the return spring 18D, and therefore, the communication member 30D is separated from the on-off valve 20, whereby the communication member 30D can be released. The push-in operation of the valve body 21 of the on-off valve 20 allows the on-off valve 20 to automatically return to the closed state from the open state. In this modification, the locking member 16D may be further changed to the side of the straw cover 9D.

Fig. 14 is an explanatory view showing a fifth modification in a mode. As shown, the beverage container 1E according to the fifth modification is provided with a locking mechanism 15E for locking the straw cover 9E, and the locking mechanism 15E includes a locking member 16E which is attached to the lockable position as shown. The suction pipe joint 3E is attached to the state in which the sliding operation is released from the position. The lock mechanism 15E includes a restraining portion 17E that engages the lock member 16E with the straw cover 9E when the lock member 16E is in the lock position, and a return spring 18E that imparts potential to the lock member 16E toward the lock position side. The on-off valve 20E is different from the above-described respective examples, and the valve body 21E is extended from the suction pipe joint 3E, and is attached to the lock member 16E, and is movable integrally with the lock member 16E. Further, the suction pipe joint 8E is provided with the transmission member 30E which is formed to protrude upwards adjacent to the valve body 21E. Therefore, when the lock container 16E is moved in the arrow direction and reaches the release position, the valve body 21E and the lock member are engaged. Since the 16E moves in the same direction and hits the communication member 30E, the communication member 30E can be used to apply the pushing operation to the valve body 21E, and the valve body 21E is elastically deformed. Further, by operating the lock member 16E to the release position, the restriction of the straw cap 9E can be released, so that the straw cap 9E can be moved to the open position side. In a state where the straw cap 9E is in the open position, the locking member 16E is moved by the return spring 18E, or the locking member 16E can be moved upward together with the straw cover 9E, whereby the communication member 30E is separated from the switching valve 20E, Thereby, since the pushing operation of the valve body 21E by the use transmitting member 30E can be canceled, the on-off valve 20E can be automatically restored to the closed state from the open state.

The on-off valve of the embodiment shown in FIGS. 1 to 9 and the modifications shown in FIGS. 10 to 14 has a valve body made of an elastic material, and the closed state and the opening are changed by the elastic deformation of the valve body. State, however, the present invention can also be implemented by an on-off valve constructed as shown in Fig. 15. Fig. 15 is an explanatory view showing another form of the on-off valve. The on-off valve 50 shown in the figure includes a partitioning plate 51 that separates the inside and the outside of the container body 2; and the moving valve body 52 is in a state in which it can be moved to the left and right direction of the figure while being in close contact with the partitioning plate 51. The setter; the return spring 53 is provided with the potential of the moving valve body 52 toward the position side of the figure; and the brake member 54 restricts the movement of the moving valve body 53. A through hole 51a whose size can be closed by moving the valve body 52 is formed in the center of the partition plate 51, and a through hole 52a larger than the through hole 51a of the partition plate 51 is formed in the moving valve body 52.

In the illustrated state, the position of the through hole 51a of the partitioning plate 51 and the position of the through hole 52a of the moving valve body 52 are mutually displaced, and the through hole 51a of the partitioning plate 51 is moved by the valve body 52. Since it is clogged, the on-off valve 50 constitutes a closed state inside and outside the closed container body 2. When the moving valve body 52 is pushed in the direction of the arrow mark from the state shown in the figure, since the positions of the through holes 51a and the through holes 52a match each other, the inside and the outside of the container body 2 communicate with each other, and the state is changed from the closed state to the open state. If the pushing operation of the moving valve body 52 is released in the state of being turned into the open state, the moving valve body 52 is restored to the position shown by the return spring 53, so that the opening and closing valve 50 can be engaged with the pushing operation. The simultaneous self-opening state is automatically restored to the closed state.

Even if the on-off valve of each of the modifications shown in the first to ninth and tenth to fourth modifications is replaced with the on-off valve 50 shown in Fig. 15, the switch can be used by each of the communication members. Since the valve 50 applies a push operation belonging to a predetermined operation, the beverage container using the on-off valve 50 has the same function as the beverage container of the above-described embodiment and each modification.

The predetermined operation applied to the on-off valve is appropriately determined in accordance with the configuration of the on-off valve. Therefore, for example, if the on-off valve is changed from the closed state to the open state by pulling some members, the pulling operation is equivalent to Scheduled operation. Further, in the case of an on-off valve that is changed from the closed state to the open state by rotating some members, the rotational operation corresponds to a predetermined operation.

When a valve body that can be changed between a closed state and an open state by elastic deformation is used, a valve body having a structure different from that of the valve body of the illustrated embodiment may be used. Further, the operating member need not be provided integrally with the valve body, and the operating member may be formed as a member different from the valve body so that the operating member and the valve body operate independently.
