Japanese Patent No. 3620042 Japanese Patent No. 4482940 Japanese Patent No. 4798553 Design Registration No. 1369904

  Since the metal lock member having the lock structure described in Patent Document 1 is made of metal, there is a problem that the elasticity is low and the operability is inferior.

  In addition, the lock member made of a resin having a lock structure described in Patent Documents 2 to 4 is superior in elasticity to a lock member made of metal, but it is exposed to the outside of the plug body and is damaged due to an impact caused by dropping or the like. In order to prevent this, it is necessary to provide a certain degree of rigidity, and it has been difficult to provide strength that can withstand a drop impact while having elasticity.

  In addition, when the elasticity is insufficient, the locking projection may scrape the plug body or the lid or the locking projection may be shaved when the lock is turned, and the locking may be loosened.

  In addition, since the substantially U-shaped lock member directly engages with the stopper or lid, decoration methods such as printing and painting may be peeled off, and plating is sufficient because the rigidity of the member increases. The elasticity was not obtained and the design was poor.

  Accordingly, in view of the above-described problems, the present invention provides a stopper for a beverage container in which a lock member has sufficient elasticity, has sufficient rigidity, and further expands the possibility of appearance design. With the goal.

  According to the first aspect of the present invention, the stopper main body is attached to the upper opening of the beverage container main body, and is pivotally supported at one end of the stopper main body by the lid hinge portion so that the upper opening of the stopper main body can be freely opened and closed. In a beverage container plug body having a lid body that opens and closes and a lock mechanism that holds the lid body in a closed state at the other end of the plug body, the lock mechanism rotates to either the plug body or the lid body A locking member that is pivotally supported and has a substantially U shape with first arm portions on both sides, a locking member having a lock hinge portion at both base ends of the first arm portion, and a pivot end point of the locking member The lock member and the corresponding lock receiving portion are included, and the lock member includes a rigid lock exterior member and an elastic lock engaging member engaged with the lock exterior member. The lock exterior member is on both sides of the first arm portion. A through hole is provided, and the lock locking member is formed in a substantially U shape having second arm portions on both sides corresponding to the first arm portion of the lock exterior member, and is inserted into the through hole from the outside. The locking engagement protrusions are provided on both ends of the second arm portion in the inner direction, and the locking engagement protrusions hold at least the lid body in the closed state, and either the plug body or the lid body. The lock receiving portion of the lock receiving portion provided is locked with elasticity.

  The invention according to claim 2 is characterized in that the lock engaging member is elastically engaged with an engaging portion provided on an outer surface of the lock exterior member.

  The invention according to claim 3 is characterized in that a part of the lock exterior member is provided with a notch, and a part of the lock engaging member is exposed from the notch.

  The invention according to claim 4 is characterized in that the notch portion is formed so as to penetrate through a substantially U-shaped inner peripheral surface of the lock exterior member, and the lock locking member is detachably disposed.

  According to the invention of claim 1 of the present invention, the lock member has a two-part configuration of a lock body member of a rigid body and a lock locking member of an elastic body. It is possible to have sufficient rigidity to withstand a drop impact while having sufficient elasticity when locking the lock. Further, by inserting the lock engagement protrusions of the lock engagement member from the outside into the through holes on both sides of the first arm portion of the lock exterior member, the elastic body is engaged when the lock engagement protrusion is engaged with the lock receiving portion. Since the second arm portion of the lock locking member is easily deformed to the outside, the lock locking projections scrape the plug body or the lid when the locking member is rotated, or the lock locking projections are scraped and engaged. It is possible to avoid loosening the stop. Further, since the lock locking member is engaged with the lock exterior member, the lock locking member cannot be easily removed from the outside, and is not lost when being cleaned. In addition, since the lock exterior member does not directly engage with the stopper body or lid when the lock member is rotated, there is no risk of peeling even if decoration such as painting or printing is applied. Even if the elasticity is improved, the reliability of the locking operation is not affected.

  According to invention of Claim 2 of this invention, an assembly is easy because a lock latching member elastically engages with a lock | rock exterior member.

  According to invention of Claim 3 of this invention, the possibility of an external design can be expanded by providing a notch part in a part of lock exterior member, and exposing a lock latching member outside.

  According to the invention described in claim 4 of the present invention, the notch portion is formed by penetrating the substantially U-shaped inner peripheral surface of the lock exterior member, so that the lock engaging member is pushed up from the notched portion penetrated. It can be removed, and even if the lock locking member is deteriorated, the parts can be easily replaced.

That is, the distance from the rotation shaft 31 to the inner side 33A of the latch receiving portion 33 and the distance to the upper end of the engaging portion 27 are formed substantially the same.

  When the lock exterior member 37 is in the first position, the first locking projection receiving portions 47 are recessed at positions corresponding to the locking locking projections 46 on both side surfaces of the locking receiving portion 33. For this reason, when the lock exterior member 37 is in the first position, the locking projection is provided so as to be locked to the first locking projection receiving portion 47 with elasticity.

  On the other hand, when the distal end of the lock exterior member 37 of the U-shaped lock 21 is in the second downward position, the lock exterior member 37 of the U-shaped lock 21 is in an unlocked state in which the lock exterior member 37 is not fitted, that is, the lock exterior of the U-shaped lock 21 The member 37 is not fitted on the latch receiving portion 33.

  When the lock exterior member 37 is in the second position, the second locking projection receiving portions 49 are recessed at positions corresponding to the locking locking projections 46 on both side surfaces of the support portion 30. Therefore, when the lock exterior member 37 is in the second position, the locking projection is provided so as to be locked to the second locking projection receiving portion 49 with elasticity.

  The lock rotation shaft 31 passes through the first shaft hole 29 on the back side of the intermediate portion of the lock button 20, and the extension shaft portion 42 of the lock rotation shaft 31 is the second shaft at both base ends of the arm portion 36. Inserted into the hole 41, both the lock button 20 and the U-shaped lock 21 are pivotally supported by a single lock pivot shaft 31.

  Further, a small convex portion 50 is formed upward on the upper surface of the latch receiving portion 33, and the small convex portion 50 is formed in a bulging shape instead of a protruding shape. Then, when the U-shaped lock 21 is turned upward, the tip inner surface of the U-shaped lock 21 is fitted onto the small convex portion 50 in the latch receiving portion 33, and the U-shaped lock is caused by the frictional force. 21 is locked and fixed to the lock receiving portion 33 (the frictional force is described for the above reason), and the lid 13 is locked.

  Next, the operation of the above configuration will be described. When the beverage is to be stored, the beverage is first stored in the container body 2 through the opening of the container body 2 which is opened in advance, and then the stopper 3 is attached to the opening end 2A and closed. At this time, the U-shaped lock 21 faces downward and is arranged at the second position.

  Thereafter, when the lid 13 is turned around the lid hinge portion 14 as a turning center, the upper inclined surface 27A of the tip of the engaging portion 27 is pushed by the lower inclined surface 32A of the tip of the engaging piece 32, When the lock button 20 is tilted so that the engaging portion 27 moves outward, and the lid 13 is pressed so as to close the lid 13, the engaging piece 32 gets over the engaging portion 27, and the engaging piece 32 Thus, the lower portion of the engaging portion 27 is locked, and the lid 13 is fixed to the plug body 11.

  Then, in order to fix the lid body 13 to the plug body 3 and, in turn, the container body 2 side, the U-shaped lock 21 is rotated upward with the lock rotation shaft 31 as the rotation center, and the U-shaped lock is secured to the latch receiving portion 33. Lock 21. Here, when the U-shaped lock 21 pivots the lock pivot shaft 31 upward, the lock latching protrusion 46 contacting the latch receiving portion 33 is elastically deformed so as to be spread outward. The first arm portion 36 of the lock exterior member 37 is configured to avoid elastic deformation such that the first arm portion 36 is pushed outward. Then, when the U-shaped lock 21 is rotated to the first position, the lock locking projection 46 that has been spread outward is elastically restored, and the first locking projection receiving portion 47 has the lock locking projection 47. 46 is in a locked state with elasticity pressed by the elastic restoring force, and the U-shaped lock 21 is fixed to the locking receiving portion 33 in the first position.

  On the other hand, in order to release the locked state by the U-shaped lock 21, the U-shaped lock 21 is rotated downward about the lock rotation shaft 31 and the U-shaped lock 21 is removed from the support portion 30 in the downward state. Fit and fix. Further, when the button surface portion 28 of the lock button 20 is pressed and the lock button 20 is rotated against the spring 34, the engagement portion 27 is retracted outward and detached from the engagement piece 32, and the lock is released. As a result, the lid 13 is biased by the elastic body 15 and rotates in the opening direction. Here, when the U-shaped lock 21 rotates the lock rotation shaft 31 downward, the lock locking projection 46 that comes into contact with the support portion 30 is elastically deformed so as to be spread outward. The first arm portion 36 of the member 37 is configured to avoid elastic deformation such that the first arm portion 36 is spread outward. When the U-shaped lock 21 is rotated to the second position, the lock latching projection 46 that has been pushed outward is elastically restored, and the second latch projection receiving portion 49 has the lock latching projection 49. 46 is in a locked state with elasticity pressed by an elastic restoring force, and the U-shaped lock 21 is fixed to the support portion 30 at the second position.

  Further, the groove 45 of the lock exterior member 37 is elastically engaged from the front end of the lock engagement member 40 to the second arm portion 39, and the lock engagement protrusion 46 of the lock engagement member 40 is connected to the lock exterior member 37. By adopting a configuration in which the through-hole 44 is inserted from the outside, the U-shaped lock 21 rotates to the first position or the second position, and the lock locking projection 46 is the first locking projection receiving portion 47. Alternatively, when the second locking protrusion receiving portion 49 is locked, the second arm portion 39 of the lock locking member 40 is easily deformed outward. Further, since the lock engagement protrusion 46 is disposed in the engagement recess 38 of the lock exterior member 37 on the lock engagement member 40, the lock engagement member 40 is not easily removed from the outside, and the lock engagement member 40 is mistaken. Never lose. Further, since the lock locking member 40 made of an elastic body is elastically engaged with the lock exterior member 37, the assemblability is good.

  As described above, in this embodiment, the stopper body 11 is attached to the opening end 2A, which is the upper opening of the beverage container body 2, and is pivotally supported by one end of the stopper body 11 by the lid hinge portion 14. A lid for a beverage container having a lid 13 that opens and closes the open end 2A of the stopper body 11 and a lock mechanism 18 that holds the lid 13 closed at the other end of the stopper body 11. 3, the locking mechanism 18 is pivotally supported by one of the plug body 11 and the lid body 13, and has a substantially U shape with first arm portions 36 on both sides. As a U-shaped lock 21 as a lock member having a lock hinge portion 43 at both base ends of the portion 36, and as a lock receiving portion corresponding to the U-shaped lock 21 at any one of rotation end points of the U-shaped lock 21. The U-shaped lock 21 includes a rigid lock exterior member 37, and the lock receiving member 33. The lock exterior member 37 is configured by an elastic lock engaging member 40 that is engaged with the outer arm member 37. The lock exterior member 37 has through holes 44 on both sides of the first arm portion 36, and the lock engaging member 40 Is formed in a substantially U shape having second arm portions 39 on both sides corresponding to the first arm portion 36 of the lock exterior member 37, and is inserted into the through hole 44 from the outside. On both ends of the second arm portion 39, and the lock locking projection 46 holds at least the lid body 13 in the closed state, so that either the plug body 11 or the lid body 13 By being elastically locked to the first locking projection receiving portion 47 and the second locking projection receiving portion 49 of the provided support portion 30 and the locking receiving portion 33, the U-shaped lock 21 is It consists of two parts: a rigid lock exterior member 37 and an elastic lock locking member 40, each with specialized functions. By causing, while have a sufficient elasticity when locked locking, it is possible to have sufficient rigidity to withstand such a drop impact. Further, by inserting the lock engagement protrusions 46 of the lock engagement member 40 into the through holes 44 on both sides of the first arm portion 36 of the lock exterior member 37 from the outside, the lock engagement protrusions 46 are engaged with the support section 30 and the engagement portions. Since the second arm portion 39 of the lock locking member 40, which is an elastic body, is easily deformed to the outside when locking to the locking portion 33, the lock locking projection 46 is plugged when the U-shaped lock 21 is rotated. It is possible to avoid the main body 11 and the lid body 13 from being shaved, or the lock latching protrusion 46 from being shaved to loosen the latch. Further, since the lock engaging member 40 is engaged with the engaging recess 38 of the lock exterior member 37, the lock engaging member 40 cannot be easily removed from the outside, and is not lost when being cleaned. . In addition, since the lock exterior member 37 is not directly locked with the plug body 11 or the lid 13 when the U-shaped lock 21 is rotated, there is no fear of peeling off even if decoration such as painting or printing is applied, and processing such as plating Therefore, even if the rigidity of the component is improved and the elasticity is lowered, the reliability of the locking operation is not affected.

  Further, since the lock locking member 40 is elastically engaged with an engagement recess 38 provided on the outer surface of the lock exterior member 37, assembly is easy.
