Description

  The present invention relates to a beverage container having a feature in an opening / closing locking mechanism of a cover body.

  Beverage containers use a metal vacuum double structure to form a heat insulation structure, or a resin single tank, etc. It is composed of a lid body that incorporates a stopper or the like and is attached to the opening of the container body, and a cover body that is attached to the lid body so as to be opened and closed by a hinge mechanism so as to cover the lid body.

  The cover body opening / closing locking mechanism generally includes a spring that biases the cover body in the opening direction, a locking that maintains the closed state of the cover body, and a locking structure that enables the locking state to be released. A so-called one-touch cover is employed in which the cover body is flipped up by the action of a spring during the unlocking operation.

  Since the cover body opening / closing locking mechanism employs a spring, when the cover body is closed, the cover body must be operated against the urging force. Since the assembling work is performed in a state where the force is suppressed, the manufacturing becomes troublesome.

  Further, a structure that does not employ a spring for opening the cover body is disclosed in Patent Document 1 (Japanese Utility Model Publication No. 2-64327). In this structure, when the lock is released, the operation claw attached to the cover body is bent by the lock release operation, and the cover body is flipped up by the repulsive force of the bending.

Japanese Utility Model Publication No. 2-64327.

  In the structure described in Patent Document 1 that does not employ a spring or the like for the opening operation of the cover body, in the unlocking operation, the operating claw is bent by the force applied during the releasing operation, and the repulsive force of the bending of the operating claw covers the cover. It is described to jump up the body. However, the bending direction of the operating claw is the moving direction of the locking member and is substantially orthogonal to the rotation direction of the cover body, and it is recognized that the bending repulsion force effectively acts on the cover body opening rotation. Absent. That is, the structure is not a one-touch opening structure.

  In addition, the locking structure disclosed in Patent Document 1 employs a spring that urges the locking member in the locking direction in order to prevent the locking member from moving and maintain the locked state. However, the manufacturing disadvantages associated with the adoption of springs remain.

  In addition, since the locking member is exposed to the outside, when it is used as a portable container, if it is accidentally touched while being carried or it is stored in a bag etc. and transported, it will be locked in the bag. There is a possibility that the cover member opens due to the stop member coming into contact with another member in the bag and pressing it. In particular, when the drinking mouth is closed with the cover body, the internal beverage may spill out.

  Accordingly, the present invention provides a beverage container having a one-touch open / close cover body opening / closing locking mechanism that does not use a spring, and secondly, a beverage container having a lock mechanism that prevents the cover body from being opened unexpectedly. A container is provided.

  A beverage container according to the present invention is composed of a container body, a lid body that is attached to the opening of the container body, and a cover body that is attached to the lid body so as to be opened and closed by a hinge mechanism so as to cover the lid body. A slide body having a latch receiving portion that attaches to the body a locking portion having a hook-shaped locking projection at the tip, and that locks the locking projection to prevent the cover body from being opened. The locking protrusion is slidably attached so that the locking protrusion can be released, and the bending portion is formed in the sliding body, and the inclined wall is provided in the bending portion, and the cover body is inclined when the cover body is closed. The cover body is locked by preventing the movement of the slide body in the unlocking direction by the contact between the wall surface and the biasing action portion, and when the lock body is unlocked by the movement operation of the slide body, It is provided with a lid opening / closing locking mechanism that flips the cover body in the opening direction by bending and returning action. It is intended to.

  Therefore, when the cover body is rotated in the closing direction to reduce the pressure, the slide body tries to move so that the locking projection is locked to the locking receiving portion, and at the same time, the biasing action portion comes into contact with the inclined wall surface. Thus, a force acts to move the slide body in the reverse direction. Therefore, the bending portion is bent downward, so that the slide body can be moved to the position where the locking operation is possible. When the locking projection reaches the locking position, the bending portion bent downward returns. By doing so, the slide body also returns and the locking projection is locked to the locking receiving portion. After the locking, the biasing action part comes into contact with the inclined wall surface to prevent the slide body from moving in the locking release direction. That is, since the slide body is prevented from moving in the unlocking direction by the contact between the biasing action portion and the inclined wall surface, the locked state is stably maintained. When the slide member is moved in the releasing direction by an external force (operation by a person), the abutting portion between the biasing action portion and the inclined wall surface is strongly pressed to bend the bending portion, and the locking projection and the locking receiving portion Is released, and at the same time, the urging action portion is flipped up by the bending return force of the bending portion, and the cover body is rotated.

  Further, the present invention (Claim 2) is provided with a lock body in which a shaft portion is provided on a slide body and an outer peripheral surface is formed on a lock surface portion and a non-locking surface portion having a shorter diameter than the lock surface portion. And a locking portion that stops the movement of the slide body in the unlocking direction by rotating the locking body by a predetermined angle and contacting the lock surface portion at a predetermined position of the lid body. .

  Therefore, when the lock body is rotated so that the non-locking surface portion faces the restraining portion, the slide body can slide, and the cover body can be locked and unlocked, and the cover body can be locked and locked. If the lock body is rotated to bring the lock surface portion and the restraining portion into contact with each other, movement of the slide body in the release direction is prevented and the lock body is locked in the locked state.

  Further, the present invention (Claim 3) is provided with a drinking part protruding from the upper surface of the lid, and a packing part for closing the upper end of the drinking part when the cover is closed at a predetermined position of the cover. Provide the sloped surface part of the latch receiving part in the latching direction of the part, move the slide body in the latching direction by the contact between the restraining part and the lock surface part, and position the latching receiver part on the sloped surface part It will be.

  Accordingly, when the slide body is moved in the locking direction by the contact between the restraining portion and the lock surface portion, and the locking receiving portion is placed on the inclined surface portion, the cover body is relatively biased in the closing direction, and the drinking mouth It is possible to secure the blockage of the portion and prevent the internal beverage from spilling out from the drinking mouth portion.

  Since the present invention is as described above, one-touch opening of the cover body is realized without adopting a spring, and in particular, by adopting a lock mechanism (Claim 2) or a pressure blocking mechanism (Claim 3). The cover body is surely prevented from being opened unexpectedly or leaked.

  The beverage container shown in the embodiment includes a container body 1, a lid body 2, and a cover body 3, and a locking mechanism 4 is incorporated in the lid body 2 and the cover body 3.

  The container body 1 includes a heat insulating container portion 11 having a metal vacuum double structure and a resin lid mounting portion 12 fixed to the opening of the heat insulating container portion 11, and the lid mounting portion is a lid body 2 on the outer peripheral surface. The screw part which can be screwed on is provided.

  The lid body 2 is provided with a hinge mechanism portion 22 for mounting the cover body 3 on a main body 21 that is cap-shaped and can be screwed to and detached from the lid body mounting portion 12, and a drinking mouth portion 23 is projected on the upper surface. Further, an air hole 24 communicating with the inside of the container body 1 is provided. A tube 25 reaching the bottom surface in the container body 1 is connected to the lower end portion of the drinking mouth portion 23.

  The cover body 3 is attached to the hinge mechanism portion 22 so that the cover body portion 31 having a face-down shape can be turned up and down freely. When closed, a packing portion 32 is provided at a position where it comes into contact with the upper end opening of the drinking mouth portion 23, and a ventilation blocking portion 33 is provided at a position facing the air hole 24.

  The lid body 2 and the cover body 3 incorporate a locking mechanism portion 4 that prevents the cover body 3 from being opened when the cover body 3 is closed and can be opened with a single touch. A slide body storage portion 41 and a restraining portion 42 are provided, a locking portion 43 and a biasing action portion 44 are provided on the cover body 3 side, and a slide body 45 and a lock body 46 which are independent members are incorporated.

  In the following description, the direction in which the hinge mechanism portion 22 is provided is defined as the base, and the open side end direction of the cover body 3 is defined as the front.

  The slide body 45 is provided with a front upper step surface portion 451a, a base lower step surface portion 451b, and an operation surface portion 451c that can be pushed forward with a finger at the base end, and the front upper step surface portion 451a. And the lower step surface portion 451b of the base is connected and integrated by the side wall surface portion 451d.

  A through hole 452 is formed in the front portion of the upper step surface portion 451a, and the front side edge of the through hole 452 is used as a latch receiving portion 453, and the base portion of the upper step surface portion 451a is provided with notches 454 in the left and right side edges. In addition, a bending portion 455 that can be bent downward is provided, and a wall portion that rises upward is provided at the base end of the bending portion 455, and the front side wall surface of the wall portion recedes toward the base. An inclined wall surface 456 is provided.

  The lower step surface portion 451b is provided with a shaft portion 457 projecting upward, and side wall surface portions 451d rise on both sides of the lower step surface portion 451b.

  The lock body 46 is rotatably mounted on the shaft portion 457, and has an outer peripheral surface including a lock surface portion 461, a non-lock surface portion 462, and a lever portion 463. The lock surface portion 461 is a lower step surface portion. The outer peripheral surface protrudes from the tip of 451b. The non-locking surface portion 462 is recessed so as to have a shorter diameter than the locking surface portion 461, and the lever portion 463 is switched so that the locking surface portion 461 and the non-locking surface portion 462 are selectively positioned ahead. Therefore, when the lock body 46 is mounted on the shaft portion 457, the lock body 46 is provided so as to protrude toward the base side at a position above the operation surface portion 451c.

  The lock body 46 is provided with an appropriate click mechanism so as to be stable at a predetermined rotation position (lock position, non-lock position).

  The slide body 45 is inserted and attached to the slide body storage portion 41 of the lid body 2 so that it cannot move in the vertical direction with the lock body 46 mounted on the shaft. A suitable range of sliding movement is possible, and it is mounted so as not to come out to the base.

  The restraining portion 42 is provided at a position where the lock surface portion 461 and the non-lock surface portion 462 of the lock body 46 face each other and at a position where the lock body portion 46 abuts strongly with the rotation of the lock body 46.

  The locking part 43 on the cover body 3 side is a position where the hook-like locking projection 431 at the tip is locked to the locking receiving part 453 when the cover body 3 is rotated in the closing direction, and the front surface at the lower end is The inclined surface of the hook-shaped locking projection 431 can enter the locking position. Further, a climbing inclined surface portion 432 is formed on the upper surface base side of the bowl-shaped portion.

  The urging action portion 44 is provided at a position that abuts against the inclined wall surface 456 and urges the slide body 45 in the locking direction (base direction) when the cover body 3 is closed.

  Thus, when the cover body 3 is in the open state, the non-locking surface portion 462 faces the restraining portion 42 and the lever portion 463 is positioned in a predetermined direction.

  In this state, when the cover body 3 is rotated in the closing direction to reduce the pressure, the hook-shaped locking projection 431 enters the through-hole 452, and the front edge of the through-hole 452 (the locking receiving portion 453) on the front inclined surface. Descend while pushing forward. As a result, the slide body 45 is applied with a force to move forward. At the same time, the urging action portion 44 abuts against the inclined wall surface 456 to prevent the slide body 45 from moving forward and push out toward the base.

  Therefore, when the pressure is further reduced, the slide body 45 is forcibly moved forward by the locking portion 43, and at the same time, the slide body 45 is moved downward by bending below the bending portion 455 of the slide body 45. Is realized. When the hook-shaped portion of the locking projection 431 reaches the lower position of the locking receiving portion 453, the forcible movement force of the slide body 45 by the locking portion 43 is released, and the bending portion 455 is moved to the biasing action portion 44. Since the slide body 45 moves upward along the contact surface with the inclined wall surface 456, the slide body 45 moves to the base, and the locking portion 43 and the locking receiving portion 453 are locked.

  In a state where the locking portion 43 and the locking receiving portion 453 are locked, the inclined wall surface 456 of the bending portion 455 and the biasing action portion 44 come into contact with each other, and the slide body 45 moves forward (locking release direction). To prevent a movement) and maintain a stable locking state.

  Further, after the cover body 3 is closed, when the lever portion 463 of the lock body 46 is operated to strongly press the stop portion 42 with the lock surface portion 461, the slide body 45 moves slightly to the base.

  In this state, the forward movement (movement in the locking release direction) of the slide body 45 is reliably prevented by the contact between the restraining portion 42 and the lock surface portion 461, and the slide body 45 even if an external force is applied to the slide body 45. Does not move forward, the cover body 3 is not accidentally opened.

  Further, when the slide body slightly moves toward the base, the latch receiving portion 453 rides on the climbing inclined surface portion 432. At this time, since the upward movement of the slide body 45 is blocked, the cover body 3 is relatively biased in the closing direction. By this urging force, the packing portion 32 strongly pressurizes the upper end opening portion of the drinking mouth portion 23, thereby preventing the internal beverage from spilling out from the drinking mouth portion 23.

  The cover body 3 is opened by operating the lever portion 463 of the lock body 46 so that the restraining portion 42 and the non-locking surface portion 462 face each other and allowing the slide body 45 to move forward (moving in the unlocking direction). When the operation surface portion 451c is pressed with a finger and moved forward, the contact portion between the biasing action portion 44 and the inclined wall surface 456 is strongly pressed, and the bending portion 455 is bent downward. When the locking projection 431 and the locking receiving portion 453 are unlocked in the course of the bending operation, the biasing action portion 44 is flipped up by the bending return force of the bending portion 455, and the cover body 3 is an opening rotation.

  Therefore, the cover body opening / closing locking mechanism is not particularly required to use a spring material, so that the locked state is maintained and the cover body 3 is urged to be released when the locking is released. It is possible to prevent the stop / release operation from being performed, and at the same time to seal the drinking mouth 23.

  Further, the present invention is not limited to the above-described embodiment. For example, as illustrated in FIG. 8, a tube body is adopted for the drinking mouth portion 23 a, and the middle portion of the tube body is closed by closing the cover body 3 a. Anyway.

  Further, as shown in FIG. 9, a drinking mouth portion 23 b may be provided on the lid 2 so as to be movable up and down, and a structure in which a spring is used to project and urge upward may be employed. In this case, when the cover body 3b is opened, the protruding biasing force of the drinking mouth part 23b acts on the opening rotation of the cover body.

  The present invention eliminates the use of a spring in the locking mechanism that realizes the closing of the cover body, and the configuration other than the locking mechanism is arbitrarily determined. As illustrated in FIG. The use of a spring other than the locking mechanism portion of the cover body is not excluded.
