Description

  The present invention relates to a stopper in a portable beverage container.

  A portable beverage container is known which is composed of a container body, a stopper attached to the opening of the container body, and a cap attached to cover the stopper. The container body employs a vacuum insulated double container made of stainless steel, and the stopper has a structure (Japanese Patent Laid-Open No. 8-289849) having a valve body that closes the outflow path from below (inside the container), or an outflow path. The structure of closing from the upper part of the outflow path is adopted so that the washing of the water becomes easy.

  The plug that closes the spout (outlet channel inner peripheral surface or bottom surface) from above is installed in the opening of the container body, and enters the outflow channel with the lower cylinder provided with the outflow channel having the spout. And a lid that is provided with a plug portion that closes the corresponding portion of the spout and is hinged to the lower cylinder so as to be freely pivoted.

  The lid body is provided with some kind of locking structure so that water leakage from the spout does not occur when the lid is closed, and when the beverage in the container body is poured out, the lid body is in an open state. In the closed state, the cap body must be attached. That is, the plug body needs to have a size that fits within a predetermined space, and has an opening urging structure and a locking structure when the mouth is closed.

  As conventional means having the above-described structure, Patent Document 1 (Japanese Patent Application Laid-Open No. 2001-149235) slides in a direction orthogonal to the hinge axis and attaches to the tip (defining the hinge axis position as the base). The latched body is provided on the upper surface of the lid, a latch receiving recess is provided on the front inner peripheral surface of the outflow passage of the lower cylinder, and the latch is locked to the latch receiving recess. A locking structure provided with a pawl is disclosed.

  Further, in Patent Document 2 (Japanese Patent Laid-Open No. 2008-137657), a locking collar portion is formed at an upper edge side portion of the outflow passage portion of the lower cylindrical body, and an L-shaped locking portion is provided at both side portions of the locking body. A locking structure provided with a claw is disclosed.

JP 2001-149235 A JP 2008-137657 A

  As a first problem, as described above, the plug body having a lid body having an opening and closing mechanism by turning in a beverage container having a cap body includes an opening biasing structure and a locking structure at the time of closing, It is necessary to form a size that fits within a predetermined space. For this reason, since the latching structure currently disclosed by patent document 1 forms the latch receiving recessed part in the front inner peripheral surface of an outflow channel part, when the drink in a container main body flows out, formation of the said recessed part is formed. Since it flows through the place, the discharge flow is disturbed, and since the place is a recess, dirt is easily deposited.

  In addition, as disclosed in Patent Document 2, when the locking collar portion is formed at the upper edge side portion of the outflow passage portion of the lower cylindrical body, the distance between the locking portion and the hinge shaft is short. In addition, it is necessary to consider the locking shape of the locking rod and the locking claw so that the pressure (biasing force in the opening direction) received by the locking contact point is large and unexpected locking is not released, and Sufficient locking area is required, and if the above-mentioned consideration is taken, the resistance to unlocking becomes large, and conversely, the operability of unlocking is impaired. Thus, the said structure is a structure provided with the conditions which conflict, and it cannot necessarily be said that it is an optimal locking structure.

  Further, as a second problem, when the locking body having the front and rear slide structure is employed, there is a problem in opening operability because the moving operation direction of the locking body is different from the operation direction of the lid.

  That is, the locking body is urged in the locking direction (forward direction) in order to maintain the locked state. To release the locking, the locking body is locked with a finger against the forward biasing force. When the body is slid and the finger is released from the locking body in that state, the lid body turns up and rotates, but at the same time, the locking body also slides back to the front, so that the lid opening operation is reliable. While maintaining the state in which the locking body is slid rearward, an operation of reducing the downward pressure on the lid by the finger is required, and a reliable opening with a simple operation is not necessarily realized.

  Further, as a third problem, in the above-described locking structure, since the operation of the locking body is restricted only by the urging mechanism attached to the locking body, if the locking body is accidentally operated, There is a risk that the beverage will spill, and when the cap body is attached without carrying out the reliable closure of the lid body, the internal beverage may leak when being carried.

  Therefore, the present invention proposes a novel beverage container stopper that solves the above-mentioned problems.

A stopper for a beverage container according to the present invention (Claim 1) is attached to an opening of a container body, and a lower cylinder provided with an attachment cylinder part to the opening of the container body and an extraction cylinder part having a spout And a lid body that has a plug portion that penetrates into the dispensing tube portion and closes the corresponding portion of the dispensing port, is pivotably connected to the lower tube body by a hinge shaft, and is biased in the opening direction. In the stopper of the beverage container, a latch receiving portion is formed on the outer peripheral surface of the outflow passage portion on the opposite side of the hinge shaft in the lower cylinder, and a locking claw is provided at a position corresponding to the latch receiving portion. The entire inverted L-shaped locking body having the provided locking piece portion and the operation piece portion located on the upper surface of the lid is pivotally supported by a support shaft that is substantially parallel to the hinge shaft at the corner position in the inverted L shape. and, and the operation lever portion exposed to the lid top surface embedded in lid swingably, pressed from the lid top surface direction of the operation lever portion Accordingly, the engagement pawl can engage withdrawal against engaging portions, with and formed by a lid body engaging structure annexed a biasing unit that biases the locking pawl into the latch receiving portion direction The operating piece portion of the locking body is formed by a swinging portion integral with the locking piece portion and a moving portion provided on the swinging portion so as to be movable in the front-rear direction. Provided with a lock mechanism that allows the base of the moving part to come into contact with the upper surface of the lid when it coincides with the outer periphery of the stopper, preventing the locking body from swinging and allowing the swinging of the moving part to protrude forward It is characterized by.

  Thus, the lid is rotated and the spout is closed by the stopper, and the locking claw of the locking body is locked to the locking receiving portion so that the closed state by the lid is maintained. When the engagement between the locking claw and the locking receiving portion is released, the lid body is rotated by the rotation urging force to be in the open state.

  Therefore, since the latch receiving portion of the lower cylindrical body is provided on the outer periphery of the outflow passage portion, there is no inconvenience in cleaning the outflow passage portion, and the latching position exists at a location away from the hinge shaft. The body rotation biasing force does not act strongly, and the rotation release operation of the locking body is easily performed.

Further, according to the present invention, the locking body is pivotally supported by a support shaft that is substantially parallel to the hinge shaft, so that the locking body can be freely pivoted. When the locking state is released by rotating and the lower pressure is released as it is, the lid body is rotated by the rotating biasing force to be in the open state. During the unlocking rotation operation of the locking body, the biasing force direction of the locking body and the opening rotation biasing force direction of the lid body coincide with each other. Even so, the operating force of the lid body causes the operating piece of the locking body to come into contact with the fingertip and the released state of the locking body is maintained and the lid body starts to rotate in the opening direction. Is made very smoothly . The locking mechanism is a mechanism that locks and releases the sliding part by moving the moving part back and forth. The moving part moves backward, and the moving part tip surface is aligned with the outer periphery of the locking piece part (non-projecting state). When the base comes into contact with the upper surface of the lid (lock receiving surface) and the locking body is prevented from rotating, and the locked portion is brought into the locked state, and the moving portion protrudes forward, the base of the moving portion moves from the lock receiving surface. Since the locking body can be turned and can be opened by operating the locking body, the operation of the locking body is restrained by this locking mechanism. Even if a force in the operation direction is applied, there will be no accidental opening.

In the beverage container stopper according to the present invention (claim 2), the locking body is housed in a recess formed in the lid, the locking piece is flush with the outer peripheral surface of the lid, and the operation is performed. those with formed by providing a single part such that the lid top surface flush, only when the mobile front edge surface coincides with the engagement piece portion periphery becomes as fit the cap body to be attached to the container body In combination with the formation of the locking body flush with the outer peripheral surface and the upper surface of the lid body, there are few protruding parts of the exposed outer shape of the plug body, and accurate storage in the cap is realized, and it is neat The appearance will be exhibited. In particular, when the lid can be opened and closed (non-locked), the cap body cannot be attached due to the protrusion of the moving part, so the cap body is attached in a surely closed state. There is no risk of occurrence.

  The configuration of the present invention is as described above, and a locking structure is provided on the outer periphery of the outflow passage portion, and a locking body that performs the locking operation is accommodated within a predetermined range, and is used for cleaning the outflow passage. There is no hindrance, locking at a position away from the hinge shaft having a high locking effect can be realized, and further excellent opening operability is provided.

  Next, an embodiment of the present invention will be described. The plug body shown in the embodiment is installed in an opening of a predetermined container body A and fits in a cap body B attached to the container body A.

  The container body A is, for example, a stainless steel vacuum double container, and a screw thread 30 for the cap body B is formed on the outer peripheral surface of the opening 02 at the top of the cylindrical container portion 01, and the plug body is mounted on the inner peripheral surface. A spiral line 04 for use is formed.

  The plug is composed of a lower cylinder 1, a lid 2, and a locking body 3 incorporated in the lid 2.

The lower cylindrical body 1 includes a mounting cylinder part 11, a dispensing cylinder part (or a drinking mouth part if the beverage container is a direct drinking type), and a crowned covering part 13. 11 and the pouring cylinder unit 12 is configured outflow path inside communicates is as Ru configured.

  The mounting cylinder portion 11 is formed with a threaded protrusion 111 on the outer peripheral surface so as to be screwed into the opening 02 of the container body A, a water seal packing 112 is mounted on the lower end, and between the dispensing cylinder portions 12. A narrowing portion is formed to provide a spout 113, and a horizontal partition plate 114 is formed at the spout 113 to block an outflow path. A base outlet 115 and a front outlet are formed in the horizontal partition 114. 116 is provided, and a vertical partition 118 that forms a passage (air passage) 117 is provided below the base outlet 115.

  The dispensing cylinder portion 12 is opened in a slightly flared shape from the spout 113, and a shaft support portion 121 that supports the hinge shaft 4 is provided at the base, and a locking claw 34, which will be described later, is locked at the front. A stopper 122 is provided.

  The crown covering portion 13 is provided so as to protrude from the upper outer periphery of the mounting cylinder portion 11 so as to cover the outer periphery of the opening end of the opening portion 01 and is formed to have a smaller diameter than the screw thread 03 for the cap body. It is what.

  The lid 2 is pivotally attached to the base outer peripheral portion of the pouring tube portion 12 with the hinge shaft 4 at the base, and is mounted so as to turn freely so as to cover the upper surface of the pouring tube portion 12. A spring body that urges the lid 2 in a direction (closing direction) that covers the upper surface of the dispensing cylinder portion 12 is attached to the shaft connection portion. In addition, a stopper portion 21 that closes the spout 113 when closing is suspended inside the lower surface of the lid, and the outer peripheral surface 22 is formed so as to be flush with the crown covering portion 13, as well as the front portion and the upper surface. The portion is formed with a recess 23 in which the locking body 3 is accommodated, and the recess 23 on the upper surface is provided with a lock receiving surface 24 slightly higher than the recess 23 on the base side.

  The locking body 3 is formed in a size that can be accommodated in the recess 23, and is composed of a vertical locking piece portion 31 and a horizontal operation piece portion 32. A locking claw 34 is provided at a position corresponding to the locking receiving portion 122 inside the locking piece portion 31, and is pivotally supported by a substantially parallel support shaft 33. A biasing portion 35 that biases in the direction of the stopper portion 122 is provided.

  The operation piece portion 32 includes a swinging portion 321 integral with the locking piece portion 31 and a moving portion 322 provided on the swinging portion 321 so as to be movable in the front-rear direction. The base end bottom surface of the moving part 322 is removed from the top surface of the lock receiving surface 24, and the base end bottom surface is positioned directly above the lock receiving surface 24 by rearward movement. The moving portion 322 is formed so that the tip end surface when the moving portion 322 is retracted is flush with the outer peripheral surface of the lid body 2, and the upper surface of the moving portion 322 is flush with the upper surface of the lid body 2. It is.

  Thus, after filling the desired beverage in the container part 01 of the container main body A, the above-mentioned stopper body is screwed into the screw thread protrusion 111 of the lower cylinder 1 to the spiral thread 04 of the container main body A, It is attached to the opening 02 of the main body A, the lid body 2 is put in the closed lock state, is covered with the cap body B, and when the beverage is taken out, the cap body B is removed and the lid body 2 is opened and the cup is also used. The beverage is poured out from the dispensing cylinder portion 12 to the cap body B and the like and used for drinking.

  The closed state will be described. As shown in FIG. 4, the locking claw 34 of the locking body 3 is locked to the locking receiving portion 122, and the locking claw 34 is locked by the biasing force of the biasing portion 35. Since it is pressed in the direction of 122, the locked state is maintained.

  Moreover, in the closed state, the outer peripheral surface of the locking body 3 (the outer surface of the locking piece portion 31 and the upper surface of the moving portion 322) is flush with the outer surface and the upper surface of the lid body 2. There are no protrusions in the exposed outer shape, and there is no hindrance to the attachment / detachment of the cap B.

  Further, even if the operating piece 32 (moving part 322) is pressed from above to operate the locking body 3 in the closed state, the base of the moving part 322 collides with the lock receiving surface 24 and the locking body. Since the locking body 3 is locked and the locking body 3 is locked, the rotation of the locking body 3 is stopped unless the locked state is released, and the lid body 2 opens by mistake. There is nothing.

  As shown in FIG. 5, the opening operation is performed by sliding the moving unit 322 forward, and when the base of the moving unit 322 is detached from the lock receiving surface 24, the locking body 3 can be rotated. .

  When the operating piece portion 32 (upper surface of the moving portion) 32 of the locking body 3 is lowered and the locking body 3 is rotated, the locking claw 34 and the locking receiving portion 122 are unlocked, and the lower pressure is maintained. When is released, the lid body 2 opens with an urging force in the opening direction (FIGS. 6 and 7).

  In particular, in the above-described operation, the urging force of the locking body 3 and the urging force of the lid body 2 are acting in the same direction in the release operation state of the locking body 3, so that the lower pressure with the finger is released. However, immediately after the release, the operation piece (moving part 322) 32 of the locking body 3 is in contact with the fingertip by the rotational biasing force of the lid 2, and the released state of the locking body 3 is maintained and the lid is closed. The rotation of the body 2 in the opening direction is started, and the opening operation is performed very smoothly.

  When closing the lid, the lid body 2 is turned in the closing direction, and the locking claw 34 of the locking body 3 is locked to the locking receiving portion 122 to close it, but the moving portion 322 moves forward. In the protruding state (non-locked state), the moving part 322 becomes in the way and the cap body B cannot be mounted. Therefore, the moving part 322 is operated and moved to the locked position, and the cap body B is attached after the mouth is securely closed, and there is no possibility of leakage of the internal beverage when it is carried.
