Description

  The present invention relates to a food and drink container used for carrying beverages and foods.

  The food and drink container includes a container main body provided with an inner periphery that forms an opening at an upper end portion, and a detachable stopper that closes the opening of the container main body. Conventional plugs generally include a plug body provided with an annular portion that is detachably coupled to an opening (shoulder cover or the like) of the container body, and a seal member that is detachable from the plug body. The seal member has a packing that can be in close contact with the inner periphery of the container body, and prevents the packing from leaking from between the opening of the container body and the sealing member of the stopper. This type of plug is configured such that the seal member and the plug main body are detachable, and the annular portion and the seal member can be cleaned by removing the seal member from the plug main body (Patent Document 1). 2).

  However, the stoppers disclosed in Patent Documents 1 and 2 have room for improvement in workability of removing the seal member from the stopper body during cleaning. That is, the plug of Patent Document 1 holds the annular part of the plug body with one hand and plugs the seal member while bending the locking claw provided on the seal member to the inner diameter side while applying force to the other hand. It was necessary to remove it from the main body. In addition, the stopper of Patent Document 2 needs to hold the annular portion of the stopper body with one hand and pull out the sealing member against the fitting force of the packing connecting the sealing member and the stopper body with the other hand. there were. That is, in any of the plugs of Patent Documents 1 and 2, when removing the seal member from the plug body, the removal operation is performed while applying force to both hands. In particular, when washing is performed using a detergent, the hand holding each part is easily slipped by the detergent attached to the annular part or the seal member. For this reason, it is difficult to put force into the hand, and it has not been easy to remove the seal member.

  Of course, it is also conceivable to simplify the removal of the seal member by setting the elastic resistance force by the locking claw or packing that couples the seal member and the plug body low. However, considering the water tightness of the stopper, it is not desirable to set the elastic resistance of the locking claw or packing low because it increases the possibility of water leakage.

  Therefore, the problem to be solved by the present invention is to simplify the work of removing the sealing member from the plug body of the food and drink container.

  In order to solve the above-described problems, the present invention includes a container body provided with an inner periphery that forms an opening at an upper end portion, and a stopper that closes the opening, and the stopper is detachable from the container body. It has a stopper main body provided with an annular portion to be coupled, and a seal member that can be attached to and detached from the stopper main body, and the seal member relates to a food and drink container having a packing that can be in close contact with the inner periphery. In the present food and drink container, the stopper main body has an engaging portion that defines the position of the seal member with respect to the stopper main body as an attachment position where the packing is in close contact with the inner periphery, and the attachment portion is used to attach the stopper main body. A movable part that is movable between a restriction position that restricts movement of the seal member defined in 1 in the removal direction to be removed from the plug body and a release position that permits movement of the seal member in the removal direction. And a movable operation portion that accepts an operation of moving the movable portion from the restriction position to the release position, and the engagement portion can release the seal member from the attachment position in the removal direction. The seal member is released in the removal direction when the movable part moves from the restriction position to the release position by the movement of the operation part. It is obtained by employing the structure induced to the ability state. In addition, in this invention, an up-down direction means the direction which becomes a direction orthogonal to the said horizontal surface when the bottom face of food-drink container is set | placed on the horizontal surface.

  According to the above configuration, when the operation unit is operated by the user, the movable unit moves from the restriction position to the release position as the operation unit moves. Since the user only moves the operation unit provided on the plug body, the operation unit can be easily operated with one hand holding the plug body. That is, the user holding the plug body with one hand moves the movable part from the operation part to the release position from the operation part with the one hand, so that the seal member is released from the plug body without resistance. Therefore, the sealing member can be easily removed from the plug body with the other hand.

  The operation unit is preferably set to move in a linear direction. According to this, since a user should just press an operation part linearly in the case of removal of a sealing member, operativity can be improved.

  In particular, when the linear direction is set to the radial direction of the annular portion, operability can be further improved. In particular, when the annular portion of the plug body is designed to have a size that can be gripped by a human hand, it is possible to operate the operating portion while gripping the plug.

  Moreover, it is preferable that the said engaging part has an engaging wall part which prevents the movement of the said sealing member to the direction different from the said removal direction. Accordingly, since the movement of the seal member is specified in the removal direction by the engagement wall portion, the user can unintentionally move the seal member in the removal direction with respect to the plug body, and the seal member can be more easily removed from the plug body. Can be removed. In addition to the removal of the seal member, the seal member is guided toward the mounting position by the engaging wall portion when the seal member is installed, so that the seal member can be easily attached to the plug body.

  The engagement wall portion includes a first engagement wall surface that prevents the seal member from moving upward relative to the plug body, and a second engagement that blocks the seal member from moving downward relative to the plug body. A wall surface, a third engagement wall surface that prevents the seal member from moving in the radial direction with respect to the plug body, and a fourth engagement wall surface that blocks rotation of the seal member in the removal direction with respect to the plug body. The stopper body urges the seal member in the removal direction until the phase deviates from above the second engagement wall surface when the movable portion moves from the restriction position to the release position. It is preferable to have an urging portion that performs. Accordingly, the seal member can be positioned in the vertical direction and the radial direction with respect to the plug main body by the first to third engaging wall surfaces, and the packing can be positioned in close contact with the opening in a watertight manner. In addition, the rotation of the seal member in the circumferential direction is stopped at the position (attachment position) at which the seal member is in an effective position for positioning on the first to third engagement wall surfaces by the fourth engagement wall surface. And the movable part in a control position prevents that a seal member moves to the removal direction from an attachment position. By this blockage, it is possible to prevent the seal member from being unexpectedly detached from the mounting position. That is, while the seal member in the mounting position can be reliably engaged with the plug body, the user moves the operation unit with one hand holding the plug body, and the biasing unit causes the seal member to move. Is rotated in the removing direction, so that the seal member can be easily removed from the plug body with the other hand.

  In addition, the biasing portion is disposed at a standby position that interferes with the connection between the annular portion and the container main body when the seal member is not attached to the stopper main body, and the seal attached to the stopper main body. More preferably, the member is disposed from the standby position to a use position allowing the coupling. Accordingly, when the user forgets to attach the seal member and tries to attach the stopper to the container body, the attachment of the stopper can be prevented by the biasing portion at the standby position. That is, prevention of forgetting to attach the seal member and simplification of removal of the seal member can be realized by using the same urging portion.

  According to this invention, when the operation unit is operated by the user, the movable unit moves from the restriction position to the release position as the operation unit moves. Since the user only moves the operation unit provided on the plug body, the operation unit can be easily operated with one hand holding the plug body. That is, the user holding the plug body with one hand moves the movable part from the operation part to the release position from the operation part with the one hand, so that the seal member is released from the plug body without resistance. Therefore, the sealing member can be easily removed from the plug body with the other hand.

  1st Embodiment as an example of the food-and-drink container which concerns on this invention is described based on an accompanying drawing (FIGS. 1-12). In addition, FIGS. 1-3 is drawn on the assumption that the bottom face of this food-and-drink container was put on the horizontal surface. The vertical direction in the figure corresponds to the vertical direction in the present invention. The radial direction refers to a direction perpendicular to the axis L passing through the center of the food and drink container in the vertical direction, and the circumferential direction refers to a direction around the axis L.

  As shown in FIG. 1, the food and drink container includes a container main body 1 that can be placed on a flat surface, and a stopper 2 provided at the upper end of the container main body 1.

  As shown in FIG. 2, the container main body 1 is formed in a bottomed cylindrical shape provided with an inner periphery 5 that forms an opening 4 in the upper end portion 3, and includes a stainless steel inner bottle 6 and an outer bottle 7. It is a vacuum double bottle (maho bottle) configured with a vacuum in between. The container body 1 has a throttle portion 9 having a reduced diameter on the inner periphery 5 on the upper end side of the inner bottle 6. The throttle portion 9 forms the minimum inner diameter portion of the container body 1. The opening 4 is formed in a region (upper side) higher than the minimum inner diameter portion of the throttle portion 9 in the use space formed in the inner bottle 6.

  Further, the container body 1 includes a shoulder cover 8 that is forcibly fitted to a welded portion located at the upper part of the inner bottle 6 and the outer bottle 7. The shoulder cover 8 is an annular cylindrical member made of a synthetic resin provided in a manner extending upward from the welded portion, and forms an opening 4 (a part thereof) on the inner surface side. The shoulder cover 8 allows the food and drink contained in the use space in the inner bottle 6 to be ingested from the opening 4 by tilting the container body 1 while the lips are applied to the outer surface. The shoulder cover 8 is formed with a male screw for screwing with the plug 2 on the outer surface.

  As shown in FIG. 2, the stopper 2 closes the opening 4 and includes a stopper body 10 coupled to the upper portion of the container body 1 and a seal member 11 that can be attached to and detached from the stopper body 10.

  The stopper body 10 includes an annular portion 12 that is detachably coupled to the shoulder cover 8 of the container body 1 and a top wall portion 13 that covers an upper portion of the annular portion 12. The annular portion 12 is formed in a size that can be grasped by a human hand (for example, a diameter of 5 to 8 cm is preferable), and an internal thread is formed on the inner surface side, so that it can be screwed with the external thread of the shoulder cover 8. Yes. For this reason, the stopper 2 can be attached to and detached from the container body 1, and the shoulder cover 8 is arranged along the inside of the annular portion 12 by this screwing operation. Note that the axis of screwing by the male screw and the female screw is set to coincide with the axis L (vertical direction) of the container body 1. On the other hand, the top wall portion 13 is formed in a disc shape formed so as to close the upper end portion of the annular portion 12, whereby the annular portion 12 and the ceiling wall portion 13 form a dome-shaped cylinder shape. ing.

  The seal member 11 includes a cylindrical portion 14 formed into a bottomed cylindrical shape by a bottom portion 14 a and a packing 15 disposed at a lower peripheral edge portion of the cylindrical portion 14. The seal member 11 is arranged in a state of being inserted from the lower side inside the annular portion 12 and the top wall portion 13 of the dome-shaped cylindrical shape, and specifies the position of the packing 15 with respect to the plug main body 10 (throttle portion 9). Further, the packing 15 has an annular shape that can be in close contact with the throttle portion 9. In the present embodiment, the close contact portion is set in the slope region 16 that extends from the minimum inner diameter portion to the upper side of the narrowed portion 9. Therefore, when the sealing member 11 is attached to the stopper main body 10, the stopper 2 is bonded to the container main body 1, whereby the packing 15 can be tightly adhered to the throttle portion 9.

  As shown in FIGS. 5 and 7, the cylindrical portion 14 has a stepped surface 14 b in which a side surface portion protrudes radially inward. Further, the cylindrical portion 14 has a first cam surface 14c and a second cam surface 14d that are formed such that the side surface portion protrudes radially inward. The operation of the step surface 14b, the first cam surface 14c, and the second cam surface 14d will be described later.

  As shown in FIGS. 2 and 3, the plug body 10 is provided with an engaging portion 17 that sets the position of the seal member 11 to a predetermined position with respect to the plug body 10 and a guide for guiding a member to be held in a predetermined direction. The unit 18 includes a movable unit 19 that is movable in response to an external force, an operation unit 20 that receives an operation from a user, and a biasing unit 21 that biases the seal member 11.

  The engaging portion 17 determines the position of the seal member 11 with respect to the plug body 10 at a position (attachment position) where the packing 15 is in close contact with the throttle portion 9 (inner circumference 5) in a watertight manner. The attachment position referred to here is such that when the stopper 2 is attached to the container body 1 with the annular portion 12 coupled to the shoulder cover 8, the packing 15 is in close contact with the above-mentioned contact portion over the entire circumference. Limited to range. For this reason, since the opening 4 is closed by the cylindrical part 14 (bottom part 14a) and the packing 15, it is possible to prevent water leakage from between the opening 4 and the seal member 11.

  Specifically, the engagement portion 17 includes a first engagement wall surface 22 located at the lower surface corner of the top wall portion 13 and a second engagement located on the upper surface of the female screw formed on the inner peripheral surface of the annular portion 12. A mating wall surface 23, a third engagement wall surface 24 formed by the inner peripheral surface of the annular portion 12 adjacent to the second engagement wall surface 23, and a fourth engagement erected in the axial direction from the second engagement wall surface 23. An engagement wall portion including a mating wall surface 25 is provided. As shown in FIG. 4, the first to third engagement wall surfaces 22 to 24 form a groove-like portion 26 extending in the circumferential direction.

  As shown in FIGS. 4 to 6, the seal member 11 includes a protruding wall 27 that extends radially outward from the peripheral edge of the upper end of the tubular portion 14 of the seal member 11. The projecting walls 27 are flat projecting pieces formed with a thickness t, and are provided at three locations in the circumferential direction.

  The aforementioned groove-like portion 26 is disposed with a predetermined gap i in the circumferential direction. Here, the gap i is set to a circumferential width that allows each protruding wall 27 to pass between the groove-like portions 26 in the vertical direction. As shown in FIG. 6, the groove-like portion 26 is formed so that the vertical groove width by the first engagement wall surface 22 and the second engagement wall surface 23 is w (at least w> t). Further, as shown in FIG. 4, the fourth engagement wall surface 25 extends along the axial direction (vertical direction) in such a manner that the left end portions of the second engagement wall surface 23 and the third engagement wall surface 24 are continuous in a side view. It is formed like a wall. Such first engagement wall surface 22 to fourth engagement wall surface 25 can be easily formed as an integral part together with the annular portion 12.

  Thus, the first engagement wall surface 22 prevents the seal member 11 from moving upward relative to the plug body 10. The second engagement wall surface 23 prevents the seal member 11 from moving downward relative to the plug body 10. The third engagement wall surface 24 prevents the seal member 11 from moving in the radial direction with respect to the plug body 10. The fourth engagement wall surface 25 prevents the seal member 11 from rotating in one circumferential direction with respect to the plug body 10. Here, “circumferential rotation in one direction” means a direction in which the seal member 11 is rotated with respect to the stopper body 10 as described later, and this direction is hereinafter referred to as “attachment direction”. .

  And such an engagement wall part (engagement wall surface 22-25) means that the groove-shaped part 26 has a dead end structure. Therefore, circumferential rotation by the projecting wall 27 to one side is prevented at the position where the projecting wall 27 enters the groove 26 and hits the dead end structure, and the position of the seal member 11 relative to the plug body 10 is specified as the mounting position. It is like that. For this reason, the engaging wall portion prevents the protruding wall 27 at the attachment position from moving further in the attachment direction.

  On the other hand, the engaging wall portion is formed in a shape in which the protruding wall 27 is released in the groove-like portion 26 (including the attachment position). That is, the engagement wall portion allows the protruding wall 27 at the attachment position to rotate in the circumferential direction to the other. Here, “circumferential rotation to the other” means a direction in which the stopper body 10 is rotated to remove the seal member 11 as described later, and this direction is hereinafter referred to as “removal direction”.

  The movement of the seal member 11 in the attaching direction and the detaching direction from the plug body 10 will be specifically described below. As shown in FIG. 7A, the circumferential phase of the seal member 11 with respect to the plug body 10 corresponds to the first phase of the plug body 1 and the seal member 11 with respect to the circumferential phase corresponding to the gap i and each protruding wall 27. And When the seal member 11 is moved upward from below the stopper body 10 in the first phase, the upper end portion of the tubular portion 14 comes into contact with the first engagement wall surface 22.

  And as shown in FIG.7 (b), by rotating the seal member 11 in the attachment direction (arrow A direction in the figure) with the seal member 11 in contact with the first engagement wall surface 22 As shown in FIG. 7C, the projecting wall 27 enters the groove-like portion 26, eventually hits the fourth engagement wall surface 25, and the seal member 11 is arranged at the mounting position. As a result, the seal member 11 cannot move in a direction other than the removal direction with respect to the plug body 10. In addition, let the circumferential direction phase of the sealing member 11 with respect to the stopper main body 10 in the state in this attachment position be a 2nd phase.

  With such an engaging portion 17, the sealing member 11 having the protruding wall 27 and the plug body 10 having the engaging wall portion (engaging wall surfaces 22 to 25) are sealed by the engaging wall portion of the engaging portion 17. The movement of the member 11 (the movement that forms the attachment direction and the removal direction) is specified. For this reason, the user can unintentionally move the seal member 11 in the direction of detachment with respect to the plug body 10, and can more easily remove the seal member from the plug body. In the present embodiment, the first engagement wall surface 22 to the fourth engagement wall surface 25 are formed integrally with the annular portion 12.

  2-4, the guide part 18 is being fixed to the lower surface of the top wall part 13, is holding the movable part 19 and the urging | biasing part 21, and this movable part 19 and the urging | biasing part 21 are carried out. Each is guided in a predetermined direction to be described later.

  As shown in FIGS. 8 and 9, the movable portion 19 is held by the guide member 18 in a state in which the movable portion 19 can reciprocally slide in a direction (straight direction) along one straight line. Here, the single straight line is set in the left-right direction in FIG. 9 (the radial direction of the annular portion 12), so that the movable portion 19 slides along the radial direction specified by the single straight line. Specifically, as shown by solid lines in FIG. 7D and FIG. 9, the movable portion 19 moves the seal member 11, which is set at the attachment position by the engaging portion 17, from the plug body 10 in the removal direction. It is possible to slide between a position to be regulated (regulated position) and a position (release position) that allows the seal member 11 to move in the removal direction as indicated by a two-dot chain line in FIGS. It has become.

  Specifically, as shown in FIG. 7 (c), when the movable portion 19 is disposed at the restriction position, the movable portion 19 is in contact with the stepped surface 14b of the seal member 11 at the attachment position. It has a locking wall 28 that faces the removal direction (arrow B direction in the figure). For this reason, the movable part 19 can prevent the circumferential rotation in the removing direction of the seal member 11 by the locking wall 28 hitting the stepped surface 14b, and the movement of the seal member 11 at the mounting position (the removal direction). It is possible to regulate the circumferential rotation).

  Further, as shown in FIG. 9, the movable portion 19 is biased toward the radially outer side of the annular portion 12 by a first return spring 29 provided between the movable portion 19 and the guide portion 18. That is, the movable portion 19 is biased from the release position side toward the specified position by the elastic force of the first return spring 29. Here, the cylindrical portion 14 is in the second phase because the side surface portion of the first cam surface 14c protrudes inward as the seal member 11 moves from the first phase to the second phase with respect to the plug body 10. The movable portion 19 is formed so as to get over the stepped surface 14b. For this reason, the locking wall 28 slides along the guide portion 18 while sliding on the first cam surface 14 c in accordance with the phase change between the first phase and the second phase of the seal member 11. When the locking wall 28 gets over the stepped surface 14 b of the seal member 11, the movable portion 19 moves to the restriction position by the elastic force of the first return spring 29.

  As shown in FIGS. 1 and 2, the operation portion 20 passes through a communication passage 30 that communicates between the annular portion 12 and the ceiling wall portion 13 and between the tubular portion 14 and the ceiling wall portion 13 in the radial direction. To the movable part 19. The moving direction of the operation unit 20 is set so as to move linearly in the radial direction of the annular portion 12. For this reason, the movable part 19 moves with the movement of the operation part 20. Moreover, since the operation part 20 is receiving the urging | biasing force from the movable part 19 urged | biased by the 1st return spring 29, it is similarly arrange | positioned radially outside. The operation unit 20 is supported at a position where an operation from the user can be received. Note that the operation unit 20 of the present embodiment is formed as a part integral with the movable unit 19.

  Thus, as shown by white arrows in FIGS. 7D and 9, the operation unit 20 positioned on the diameter line of the annular portion 12 is linearly moved in one radial direction by the user (that is, as shown in FIG. The operation part 20 presses in the radial direction of the annular part 12). Then, the movable part 19 moves from the restriction position to the release position. That is, the seal member 11 restricts the seal member 11 from rotating circumferentially in the removal direction with respect to the plug body 10 when the movable portion 19 moves from the restriction position to the release position by the movement of the operation portion 20. Disappears. For this reason, the seal member 11 is brought into a releasable state in the removal direction. Therefore, if the seal member 11 at the mounting position (second phase) is rotated in the direction of removal (the direction of arrow B in the figure), the seal returns to the first phase as shown in FIG. The member 11 can be removed from the plug body 10.

  Further, as shown in FIG. 7A, the seal member 11 is arranged in the first phase with respect to the plug body 10 by the user, and the seal member 11 is attached to the plug body 10 in the mounting direction (in FIG. 7A). Rotated in the direction of arrow A). Then, the locking wall 28 of the seal member 11 slides along the guide portion 18 while sliding on the first cam surface 14c, and eventually gets over the step surface 14b. As a result, the seal member 11 is disposed at the attachment position, and the movable portion 19 is moved from the release position to the restriction position by the elastic force of the first return spring 29. Therefore, the movement of the seal member 11 with respect to the plug body 10 is restricted.

  As shown in FIGS. 3, 10, and 11, the urging portion 21 is disposed on the side of the movable portion 19, and includes a follower body 31 and a second return spring 32. The follower body 31 is held so as to be reciprocally slidable in a direction along one straight line with respect to the guide portion 18, and the slide direction is set to be the same direction (parallel direction) as the slide direction of the movable portion 19. Has been. The second return spring 32 is interposed between the follower body 31 and the guide portion 18, and is attached from the radially inner side to the radially outer side (sliding direction) of the follower body 31 by its elastic force. Rush. As a result, the follower body 31 connects the annular portion 12 and the shoulder cover 8 (container body 1) when the seal member 11 is not attached to the stopper body 10, as indicated by the solid line in FIGS. It is arranged at a position to disturb (standby position). On the other hand, the follower body 31 allows the annular portion 12 and the shoulder cover 8 (container body 1) to be coupled by the seal member 11 attached to the stopper body 10 when the sealing member 11 is attached to the stopper body 10. It is arranged at the position to be used (use position).

  Since the second cam surface 14d of the cylindrical portion 14 of the seal member 11 is reduced in diameter from the first phase toward the second phase, the follower body 31 is formed as shown in FIGS. ), The second cam surface 14d slides in accordance with the phase change between the first phase and the second phase of the seal member 11. Therefore, the follower body 31 in the standby position moves from the standby position on the radially outer side toward the use position on the radially inner side.

  According to the food and drink container according to the embodiment as described above, when the operation unit 20 is operated by the user, as indicated by the white arrow in FIG. Thus, the movable part 19 moves from the restriction position (position where the movable part 19 is indicated by a solid line) to the release position (position where the movable part 19 is indicated by a two-dot chain line). Here, since the engaging portion 17 is formed in a shape in which the protruding wall 27 is released in the groove-like portion 26, the seal member 11 in the mounting position is in the removal direction. It is easy to rotate in the circumferential direction without resistance. That is, when the user holding the plug body 10 with one hand moves the movable part 19 from the operation unit 20 to the release position from the operation unit 20 with the one hand, the seal member 10 can be removed from the plug body 10 without resistance. Since it is made into the release state which can be removed, the seal member 11 can be easily removed from the plug body 10 with the other hand.

  Further, since the operation unit 20 is set to move in the linear direction, the user only has to press the operation unit 20 linearly when removing the seal member 11, thereby improving operability. Can do. In addition, the operability of the operating portion 20 is further improved because the linear direction is set to the radial direction of the annular portion 12. Further, when the annular portion 12 is designed in a size that can be gripped by a human hand, the operation portion 20 can be operated while gripping the stopper 2.

  Further, since the urging portion 21 is disposed at the standby position and the use position, when the user tries to attach the stopper 2 to the container body 1 without attaching the seal member 11, the biasing portion 21 is at the standby position. The attachment of the plug 2 can be prevented by the urging portion.

  A second embodiment will be described with reference to FIG. Only the differences from the first embodiment will be described below. In the present embodiment, when the movable portion 19 moves from the restriction position to the release position, the biasing portion 21 biases the seal member 11 in the removal direction until the phase deviates from above the second engagement wall surface 23.

  As shown in FIGS. 13A to 13C, the cylindrical body 14 is formed with a second cam surface 14 d facing it so as to receive a biasing force from the follower body 31 in the use position. Therefore, when the operation unit 20 is operated by the user, the movable unit 19 moves from the restriction position to the release position, so that the seal member 11 can be released in the removal direction. Then, the follower body 31 in the use position is urged toward the standby position by the urging force of the second return spring 32 and tries to return to the standby position. The return of the follower body 31 is converted into rotation in the direction of removing the seal member 11 (arrow B direction) by the second cam surface 14d. In this manner, the follower body 31 rotates the seal member 11 in the second phase in the removal direction (arrow B direction) to the first phase when the movable portion 19 moves from the restriction position to the release position. . That is, according to the second embodiment, the removal of the seal member 11 can be further simplified. Further, when the seal member 11 is not attached to the plug body 10, the biasing portion 21 is disposed at the standby position, so that it is possible to reliably prevent forgetting to attach the seal member 11.
