Description

  The present invention relates to a single-open bottle provided with a single-open lid that opens and closes around one side of the upper end portion of the bottle body, and particularly relates to a single-open bottle that can prevent inadvertent opening of the single-open lid.

  The single-open bottle is formed so that you can directly drink it by holding it with one hand and opening the single-open lid. To prevent inadvertent opening of the lid, lock the single-open lid in the closed position and hold it with one hand. The finger can be unlocked with the finger of the hand and the single-open lid can be opened.

  As such a single-open bottle, conventionally, a lock member that is provided at the end of the bottle body on the single-open lid side so as to be swingable and has a lock claw that engages with the single-open lid, and the lock member What is provided with a lock mechanism composed of three members: a base material that is swingably attached to the same swinging shaft, and an operation unit that is attached to the surface side of the base material and is slidable in the vertical direction. Yes (for example, see Patent Document 1).

  The operation part has a locking projection on the back surface, the base material has a slit extending through in the vertical direction, and the operation part is located at the upper end of the slide range inside the bottle body. A locked portion that is locked to the locking projection when the locking is performed is provided. When the operation unit is located at the upper end of the slide range and is in the lock position, even if the operation unit is pressed toward the bottle body side, the locking projection is locked to the locked part and moves toward the bottle body side of the operation unit. Movement is restricted. As a result, the swinging of the base and the lock member is restricted, the engagement between the lock claw and the single-open lid is maintained, and the lock of the single-open lid is held. On the other hand, when the operating part is slid downward and is in the unlocking operation position at the lower end of the sliding range, the locking projection of the operating part is blocked by the locked part as the operating part is pressed toward the bottle body side. It moves to the bottle body side without being done. As a result, the base and the lock member are swung to disengage the lock claw and the single-open cover, and the single-open cover is unlocked. As a result, the single-opening lid is urged in the opening direction by a spring provided on the opening / closing shaft of the single-opening lid, so that the single-opening lid is opened.

  As described above, in the single-open bottle of Patent Document 1, the operation unit is slid downward to release the locked state, and then the operation unit is pressed toward the bottle body, thereby opening the single-open lid. . The operation portion protrudes sufficiently outward at the lock position for easy operation, but is in the same protruding state as that at the lock release operation position.

  In addition, as a conventional single-open bottle provided with another lock mechanism, an engagement piece provided on the outer surface of the rotating end of the single-open lid, and an outer surface of the cap member of the bottle body, the intermediate portion is a shaft. It has a lock mechanism composed of a seesaw-type lock button that is pivotally supported by a member and is swingably mounted in the inside and outside of the plug member, and a stopper that is slidably provided on the outer peripheral wall of the plug member. (See, for example, Patent Document 2).

  The lock button has an engagement groove at the upper end that can be engaged with the engagement piece of the single-open lid, and the engagement groove is engaged with the locking piece of the single-open lid on the inner surface of the lock button. A spring that biases in the direction of mating is arranged. The stopper has a stopper piece at the upper end, and when the stopper is in the lock position, which is the upper end of the slide range, the stopper piece is inserted between the back surface of the lower end of the lock button and the outer peripheral wall of the plug member. The movement of the lock button in the unlocking direction is restricted. On the other hand, when the stopper is slid downward and reaches the unlocking operation position which is the lower end of the sliding range, the stopper piece is retracted from between the back surface of the lower end of the lock button and the outer peripheral wall of the plug member. After that, by pressing the lower surface of the lock button, the lock button rotates and the upper end moves away from the single-open lid, and the engagement between the lock groove of the lock button and the single-open lid engagement piece is released. Thus, the one-sided lid can be opened.

  As described above, in the single-open bottle of Patent Document 2, the stopper piece is slid in the direction away from the single-open lid to release the locked state, and subsequently, the lock button separate from the stopper piece is pressed. Thus, the one-sided lid is opened.

  However, in the single-open bottle of Patent Document 1, when the operation part is in the unlocking operation position, if the single-open bottle falls over or contacts another object, the operation part that protrudes outward is the bottle body side. However, the lid is opened regardless of the operator's intention, and the beverage in the bottle body leaks.

  In addition, when unlocking the one-sided lid, when the operating unit is slid to reach the lower end of the sliding range, the operating unit is pressed by the pressing force that is applied during the sliding operation, and the operator's There is a problem that the single-opening lid opens without intention. Specifically, the operation unit is slid in a direction away from the swing shaft of the base and the lock member, and the slide operation is finished at a position where the swing arm length is long. Regardless of the person's intention, the operation unit is pressed and the one-sided lid is opened.

  Moreover, since this lock mechanism is comprised by three members and there are many number of parts, there exists a possibility of causing the raise of the manufacturing cost of a single-open bottle.

  On the other hand, the single-open bottle of Patent Document 2 is composed of two members and has a small number of parts. However, after the stopper is slid away from the lock button to the unlocking operation position, the lock button is pressed and the piece is opened. Since the opening lid is opened, it is necessary to intermittently operate different members of the stopper and the lock button, and there is a problem that the operability is poor.

  Then, this invention makes it a subject to provide the single-open bottle which can prevent the open of the single-open lid by a fall or contact with another thing by a small number of parts, and without deteriorating operability. It is another object of the present invention to provide a single-open bottle that can prevent the single-open lid unintended by the operator from being opened.

  In order to solve the above-mentioned problem, the single-open bottle of the present invention can be unlocked by unlocking the bottle main body, the single-open lid that opens and closes around the upper end one side of the bottle main body, and the single-open lid is locked in the closed position. And a lock member that is housed in the storage chamber and that locks the single-open lid in the closed position, and a lock that holds the lock member in a locked state. A lock release member that is moved between a position and a lock release operation position for releasing the lock state of the lock member, and the lock release member abuts on a locked portion in the storage chamber at the lock position. Thus, the unlocking operation of the lock member is restricted.

  According to the above configuration, when unlocking the one-sided lid, the unlocking member is moved from the locking position to the unlocking operation position, and the locking member provided with the unlocking member is driven by the response of the unlocking member. Operated. Thereby, the lock | rock of a one side cover is cancelled | released and opening | release is attained. As described above, since the single-open lid can be opened by performing the drive operation of the lock member continuously after the movement operation of the lock release member, a single-open bottle with good operability can be obtained.

  In addition, since the lock release member is in the accommodation chamber together with the lock member, the lock release member can be prevented from being driven together with the lock member even if the lock release member falls over in the state of being in the lock release operation position or contacts another object. In particular, since the unlocking member abuts against the locked portion in the storage chamber at the locked position and the unlocking operation of the locking member is restricted, the unlocking of the locking member can be forcibly prevented.

  In addition, since the lock mechanism can be configured by two members of the lock release member and the lock member, the number of parts of the single-open bottle can be reduced, and the manufacturing cost can be reduced.

  In the one-sided bottle according to an embodiment, the unlocking member has an operation portion that protrudes outward, and the operation portion of the unlocking member has an unlocking operation position that is larger than the outward protrusion amount at the lock position. The amount of outward protrusion at is smaller.

  According to the above embodiment, when the unlocking member is in the unlocking operation position, even if the single-opening bottle falls down or comes into contact with another object and the operation unit is pressed, the single-opening lid can be prevented from being opened. It is possible to prevent erroneous opening that is not intended by the operator.

  In the single-open bottle of one embodiment, the amount of protrusion of the lock release member from the storage chamber at the unlocking operation position is smaller than the amount of protrusion from the storage chamber at the lock position.

  According to the above embodiment, even when the lock release member falls over in the unlock operation position or contacts another object, it is possible to prevent inconvenience that the lock release member is driven together with the lock member. Unintentional opening of the single lid can be prevented.

  In the single-open bottle according to one embodiment, the unlocking member has a smaller protruding amount from the surface of the locking member at the unlocking operation position than the protruding amount from the surface of the locking member at the locking position.

  According to the above embodiment, even when the lock release member falls over in the unlock operation position or contacts another object, it is possible to prevent inconvenience that the lock release member is driven together with the lock member. Unintentional opening of the single lid can be prevented.

  In the single-open bottle of one embodiment, the lock position of the unlocking member is a position far from the single-opening lid, and the unlocking operation position of the unlocking member is a position close to the single-opening lid.

  According to the above embodiment, when unlocking the single-open lid, the unlock member moves closer to the single-open lid as the unlock member is moved from the lock position to the unlock operation position. Therefore, when the one-open lid is opened along with the swing of the lock member, the lock release member is driven to release the lock in a direction in which the swing arm length of the lock member is shortened. Therefore, compared with the conventional case in which the unlocking member is driven in the direction in which the swing arm length of the locking member becomes longer at the time of unlocking, the locking member is released regardless of the operator's intention by the driving force of the unlocking member. Inconvenience of being driven can be prevented.

  The one-sided bottle according to one embodiment has the lock member pivotally attached to the bottle body, having a lock claw at the upper end and a guide portion for guiding the lock release member at the lower portion, and releasing the lock. The member has a sliding portion that is guided by the guide portion of the lock member and slides in the vertical direction at the top, and an operation portion that protrudes outward at the lower end. It has an engaging part with which a nail | claw engages.

  According to the above-described embodiment, when unlocking the one-sided lid, the operation portion provided at the lower end of the unlocking member is operated, and the unlocking member slides along the guide portion of the locking member. To reach the unlocking operation position. The unlocking member at the unlocking operation position is pressed, and the locking member is driven to swing together with the unlocking member, so that the engagement between the locking claw of the locking member and the engaging portion of the one-sided lid is released. The opening lid can be opened.

  The single-open bottle of one embodiment has a locking portion that can be locked to the bottle body at the lower end when the unlocking member is in the locked position, and when the unlocking member is in the locked position, the unlocking member The distance between the locking portion and the locked portion of the bottle body is smaller than the engagement distance between the lock claw of the lock member and the engagement portion of the one-sided lid.

  According to the above embodiment, when the unlocking member is in the locked position, even if the operation portion of the unlocking member is pressed, the locking portion of the unlocking member is locked to the locked portion of the bottle body. The engagement state between the lock claw of the lock member and the engagement portion of the one-sided lid is maintained. Therefore, the locked state of the one-sided lid is reliably maintained.

  In the single-open bottle of one embodiment, when the single-open lid is locked in the closed position, at least one of the lock member and the single-open lid is elastically deformed.

  According to the above embodiment, when the opened single-open lid is closed, the lock member and the single-open lid are placed under the state where the locking portion of the unlocking member in the lock position is locked to the locked portion of the bottle body. Since at least one of them is elastically deformed, the lock claw of the lock member and the engaging portion of the one-sided lid can be engaged.

  As described above, according to the single-open bottle of the present invention, since the lock member and the lock release member are in the storage chamber, the single-open bottle falls over while the lock release member is in the unlock operation position. Even if it contacts, the lock release member can be prevented from being driven together with the lock member, and the inconvenience of opening the one-sided lid regardless of the operator's intention can be prevented. In addition, since the unlocking member is brought into contact with the locked portion in the storage chamber at the locked position and the unlocking operation of the locking member is restricted, the unlocking of the locking member can be forcibly blocked.

  FIG. 1 is a cross-sectional view showing a single-open bottle according to an embodiment of the present invention. This single-open bottle has a bottle main body 1 having a vacuum heat insulating space 2 between an inner wall and an outer wall made of stainless steel, and a female screw that is screwed into a male screw 3 formed on the outer wall of the mouth 1a of the bottle main body 1. , A synthetic resin shoulder member 5 attached to the bottle body 1 via a seal packing 9, and a synthetic resin piece rotatably attached to the back side of the shoulder member 5 via a rotation shaft 6. An open lid 7 and a lock mechanism 8 provided on the front side of the shoulder member 5 and formed to lock and unlock the single open lid 7 in the closed position are provided.

  The bottle body 1 has a body portion 1b that is slimmed to the extent that it can be held by one hand, and the upper portion of the body portion 1b is adjacent to the lower end of the shoulder member 5 attached to the mouth portion 1a than the body portion 1b. It is formed on a slightly small neck 1c. Holding the body 1b and neck 1c of the bottle body 1 with one hand, the operation of the lock mechanism 8 with the finger of the hand held by one hand, the opening operation of the single-open lid 7 and the opening of the single-open lid 7 After this, the shape is such that a direct drinking operation by the drinking mouth 14 described later is easily performed.

  The shoulder member 5 has a substantially cylindrical shape that covers the mouth portion 1a of the bottle body 1, and a bulging portion that accommodates the lock mechanism 8 is formed on the front side. A protective member 51 surrounding the lock member 11 and the lock release member 12 described later is integrally formed at the most protruding portion of the bulging portion. On the top surface of the shoulder member 5, a cylindrical drinking mouth 14 is formed so as to protrude at a position deviated from the center to the front side in plan view.

  The one-sided lid 7 has a generally dome shape with an open lower end, and is formed so that the lower end is fitted to the upper end of the side surface of the shoulder member 5. A seal packing 16 is provided on the inner side surface of the ceiling portion of the one-sided lid 7 so as to be in close contact with the end surface of the drinking mouth 14 when the one-sided lid 7 is closed. A torsion spring 131 is provided around the rotation shaft 6 for attaching the one-sided lid 7 to the shoulder member 5 to urge the one-sided lid 7 in the opening direction. Further, when the single-opening lid 7 is closed, the single-opening lid 7 is urged in the opening direction by the restoring force of the seal packing 16 that is in close contact with the drinking mouth 14. Accordingly, when the lock mechanism 8 is released with the thumb while holding the bottle body 1 with one hand, the one-sided lid 7 is easily opened by the urging force of the rotating shaft 6 and the seal packing 16, and the bottle body 1 is tilted as it is and the shoulder member 5 is tilted. It is possible to drink directly from the mouth 14.

  The lock mechanism 8 includes a lock member 11 that is locked in the engagement groove 71 of the single-open lid 7 and locks the single-open lid 7 in the closed position, and an unlock member 12 that releases the lock by the lock member 11. . FIG. 1 shows a state in which the unlocking member 12 is in the unlocking operation position.

  2A and 2B are cross-sectional views showing the lock mechanism 8 extracted. 3 (a) is a front view of the lock member, FIG. 3 (b) is a side view of the lock member, FIG. 3 (c) is a rear view of the lock member, and FIG. 3 (d) is FIG. It is sectional drawing in the AA of (b). 4A is a front view of the unlocking member, FIG. 4B is a side view of the unlocking member, FIG. 4C is a rear view of the unlocking member, and FIG. These are sectional drawings in the BB line of Drawing 4 (a).

  As shown in the front view of FIG. 3A, the lock member 11 of the lock mechanism 8 is formed by integrally forming a semicircular upper portion and a rectangular lower portion. A lock claw 111 is formed on the back side surface of the upper portion of the lock member 11, and a guide portion 112 for guiding the lock release member 12 is formed in the center of the lower portion of the lock member 11 in the thickness direction. The guide portion 112 is formed between the front plate portion 113 on the front surface side and the back plate portion 114 on the back surface side, and between the front plate portion 113 and the back plate portion 114 from the center in the upper width direction. A sandwiched portion 115 extending downward is provided. As shown in the front sectional view of FIG. 3D, an upper lock notch 115a and a lower lock notch 115b are provided on both side surfaces of the sandwiched portion 115. The front plate portion 113 that defines the surface side of the guide portion 112 is formed so that the thickness increases toward the upper side. Thereby, the guide part 112 is inclined with respect to the surface of the front plate part 113 in a side view. A recess 11 b is formed on the lower end surface of the plate portion 113 on the surface side of the lock member 11. The recess 11b is formed at a position adjacent to the operation portion 124 when the unlocking member 12 is in the unlocking operation position. As will be described in detail later, the operation portion 124 of the unlocking member 12 at the unlocking operation position is formed with a small projection amount that projects from the surface of the lock member 11. Thus, the operating portion 124 can be easily operated even when the protrusion amount is small. A through hole 11c into which the swing shaft is inserted is formed in the lower part of the upper portion of the lock member 11 so as to extend in the width direction.

  As shown in the front view of FIG. 4A, the unlocking member 12 of the locking mechanism 8 has a rectangular lower plate 121 in a front view, and the upper side of the lower plate 121 is bent toward the sides facing each other. Two sandwiching rods 122 having a flange 122a at the front end and two guide plates 123 disposed on both outer sides of the sandwiching rod 122 and projecting to the back side are integrally formed. In addition, an operation portion 124 that protrudes to the front surface side is provided at the lower end of the lower plate 121. At the lower end of the operation portion 124, a locking portion 124a bent to the back side is formed. As shown in the side view of FIG. 4B and the cross-sectional view of FIG. 4D, the unlocking member 12 is formed in a vertically long parallelogram in a side view.

  As shown in FIGS. 2A and 2B, the unlocking member 12 is housed in the guide portion 112 of the lock member 11 and is slidably attached to the lock member 11. Specifically, the upper part of the unlocking member 12 is inserted into the guide part 112 of the lock member 11, and the pin 122 of the unlocking member 12 sandwiches both sides of the sandwiched part 115 in the guide part 112 of the lock member 11. The inner surface of the guide plate 123 of the lock release member 12 is assembled with the both side surfaces of the back plate portion 114 of the lock member 11 sandwiched therebetween. The pin 122 is elastic and elastically deforms with the pinched portion 115 sandwiched between the two pinches 122 to apply a pressing force to the side surface of the pinched portion 115 from the tip of each brim 122a. It is like that. With this pressing force, the flange 122a is pushed into the notches 115a and 115b to be fitted. The upper part of the unlocking member 12 is slidable in the guide part 112 of the locking member 11, and when the unlocking member 12 is in the upper unlocking operation position, the hook part 122a of the sandwiching bar 122 is clamped. It fits into the unlocking notch 115a of the part 115. Further, when the unlocking member 12 is in the lower locking position, the flange 122 a of the pin 122 is fitted into the lock notch 115 b of the pinched portion 115. Thus, the lock release member 12 is held in the lock release operation position and the lock position with respect to the lock member 11, respectively. Further, the lock release member 12 slides along the guide portion 112 inclined with respect to the surface of the lock member 11. As a result, the protrusion amount at which the operation portion 124 protrudes from the surface of the protection member 51 is smaller in the protrusion amount at the unlock operation position at the upper end than at the lock position at the lower end. Furthermore, the amount of protrusion from which the operating portion 124 protrudes from the surface of the lock member 11 is also smaller in the amount of protrusion at the upper end unlocking operation position than the amount of protrusion at the lower end lock position.

  The lock mechanism 8 including the lock release member 12 and the lock member 11 is accommodated in the bulging portion of the shoulder member 5. 5A and 5B are front views showing a state in which the lock mechanism 8 provided at the bulging portion of the shoulder member 5 is viewed from the front side. In the bulged portion of the shoulder member 5, a substantially rectangular storage chamber 52 is formed so as to contact the upper end edge of the shoulder member 5 in a front view. In the storage chamber 52, the lock member 11 is swingably attached by a swing shaft that passes through the through hole 11c. One end of a compression spring 53 is fixed to the back side wall of the storage chamber 52, and the tip of the compression spring 53 comes into contact with the back side surface of the lock member 11 so that the lock claw 111 is locked in the direction toward the bottle body 1 side. The member 11 is biased by the compression spring 53. In the storage chamber 52, a locked portion 54 formed by forming a step portion on the lower surface of the storage chamber 52 is provided. At the upper end of the locked portion 54, a protrusion 54a protruding to the front side is provided. The locking portion 124a of the unlocking member 12 in the locked position comes into contact with the locked portion 54, and the releasing operation of the unlocking member 12 and the locking member 11 is restricted. The locking portion 124a of the unlocking member 12 is locked to the protrusion 54a of the locked portion 54, so that the unlocking operation cannot be performed even if an unreasonable pressing operation is performed. Yes. That is, the operation part 124 of the unlocking member 12 in the locked position is not unlocked by the locking part 124a of the unlocking member 12 coming into contact with the locked part 54 in a normal pressing operation. If it is forcibly pressed by an ununderstood person or forcibly pressed by another person unintentionally, an upward unlocking force may be applied. Even in such a case, since the locking portion 124a of the unlocking member 12 is locked to the protrusion 54a of the locked portion 54, the unlocking member 12 can be prevented from unintentionally moving to the unlocking operation position. .

  The upper portion of the lock member 11 attached in the accommodation chamber 52 of the shoulder member 5 protrudes from the upper end of the shoulder member 5. The single-sided lid 7 fitted to the upper end of the shoulder member 5 is formed with a generally semicircular lid-side storage chamber 72 in contact with the lower end edge of the single-sided lid 7 in a front view. An engagement groove 71 is formed inside. When the single-open lid 7 is closed, the lid-side storage chamber 72 is connected to the upper end of the storage chamber 52, and the upper portion of the lock member 11 is fitted into the lid-side storage chamber 72, and the engagement groove in the lid-side storage chamber 72 is engaged. The lock claw 111 of the lock member 11 is engaged with 71.

  Hereinafter, the locking operation and the unlocking operation of the one-sided lid 7 by the locking mechanism will be described. FIG. 1 shows a state in which the unlocking member 12 is in the unlocking operation position and the single-opening lid 7 is locked, while FIG. 2 shows a state in which the unlocking member 12 is in the locking position and the single-opening lid 7 is locked. Is shown.

  First, the opened one-sided lid 7 is rotated around the pivot shaft 6 to perform a closing operation, and the lower end of the one-sided lid 7 is fitted to the upper end of the shoulder member 5. Immediately before the lower end of the single-open lid 7 is fitted to the upper end of the shoulder member 5, the upper end of the lock claw 111 of the lock member 11 contacts the lower end of the single-open lid 7. At this time, when the unlocking member 12 attached to the locking member 11 is in the locked position, the locking portion 124 a at the lower end of the unlocking member 12 is locked to the locked portion 54 in the storage chamber 52 of the shoulder member 5. Thus, the rocking of the lock member 11 is restricted. In this state, when the closing force is applied to the single-opening lid 7 by the operator, the lock member 11 and the single-opening lid 7 that are in contact with each other are elastically deformed, and the lower end of the single-opening lid 7 is the locking claw of the locking member 11. The lock claw 111 of the lock member 11 is engaged in the engagement groove 71 of the one-sided lid 7 over the upper end of 111. As a result, the single-open lid 7 is locked in a closed state. Therefore, even if the lock release member 12 is automatically returned to the lock position by urging the lock release member 12 with a spring or the like, there is no problem that the lock mechanism 8 is damaged when the one-sided lid 7 is closed.

  The lock member 11 is preferably formed with higher rigidity than the single-open lid 7 in order to ensure durability. Further, a thickness relationship or the like that is easily elastically deformed from the periphery of the engaging groove 71 of the opening lid 7 is set so that the deformation amount of the single-opening lid 7 becomes larger than the deformation amount of the lock member 11 during the closing operation. Is preferred.

  Further, when closing the single-opening lid 7, the unlocking member 12 is often in the unlocking operation position. In this case, after the lower end of the single-opening lid 7 comes into contact with the upper end of the lock claw 111 of the locking member 11, The member 11 swings and moves outward against the urging force of the compression spring 53, and the one-sided lid 7 is further rotated to be in a closed state.

  When the single-opening lid 7 is closed, the unlocking member 12 is set to the locked position, thereby preventing the single-opening lid 7 from being opened. That is, even if the operator applies a pressing force to the operation portion 124 of the unlocking member 12 or the recess 11b of the locking member 11, the locking portion of the unlocking member 12 in the locked position as shown in FIG. 124a is locked to the locked portion 54 in the storage chamber 52 of the shoulder member 5, and the swinging of the lock member 11 is restricted. When the locking portion 124 a is locked to the locked portion 54, the lock claw 111 of the lock member 11 remains engaged with the engagement groove 71 of the one-sided lid 7. Therefore, even if the operation unit 124 is pressed by an erroneous operation, a fall, or contact with another object, the locked state of the one-sided lid 7 is not released. Further, even if the locking portion 124a of the unlocking member 12 receives an upward force due to the operation portion 124 being pressed strongly, the locking portion 124a is engaged with the protrusion 54a at the upper end of the locked portion 54. Since it stops, it can prevent that the latching | locking part 124a falls from the to-be-latched part 54. FIG. Therefore, the locked state of the single-open lid 7 can be stably maintained.

  When opening the one-sided lid 7 in the locked state, the operation portion 124 is pushed upward by the operator, and the flange portion 122a of the pin 122 of the lock release member 12 is unlocked notch of the pinched portion 115 of the lock member 11. 115a is engaged. Thereby, as shown in FIG. 5B, the operation unit 124 is held in a state of being close to the lower end of the lock member 11. Subsequently, the operation unit 124 is pressed by the operation, and the lock release member 12 and the lock member 11 swing around the swing shaft against the urging force of the compression spring 53. As a result, the engagement between the lock claw 111 of the lock member 11 and the engagement groove 71 of the one-sided lid 7 is released, and the one-sided lid 7 is driven and released by the biasing force of the torsion spring.

  When the unlocking member 12 is moved from the lock position to the unlocking operation position, the single-opening bottle of this embodiment can prevent the opening of the single-opening lid 7 not intended by the operator. Specifically, when operating the operation unit 124 to move the lock release member 12 from the lock position to the lock release operation position, the operation unit 124 is slid upward, so that the swing arm length around the swing shaft of the lock member 11 is increased. Becomes shorter. Conventionally, since the operation unit is operated in a direction in which the swing arm of the lock member becomes longer, the lock member is pressed by a force for performing a slide operation, and the one-sided lid is unintentionally opened. On the other hand, the single-open bottle of the present embodiment performs the unlocking by sliding the unlocking member 12 in the direction in which the swing arm length is shortened and the protruding amount of the operation unit 124 is reduced. It is possible to prevent the lock member 11 from being swung by the force applied to the operation portion 124 of the lock release member 12. Therefore, the inconvenience of unintentionally opening the one-sided lid 7 when only unlocking by the unlocking member 12 can be prevented.

  As described above, driving the unlocking member 12 in the direction approaching the one-sided lid 7 for unlocking is an operation opposite to the conventional unlocking operation, and is opposite to the intuitive unlocking operation. This is a direction operation. Therefore, it is necessary for the single-open bottle of this embodiment to drive the lock release member 12 to the single-open lid 7 side with a clear intention contrary to intuition for unlocking. Moreover, the lock release member 12 is driven so that the swing arm length of the lock member 11 is shortened. Therefore, it is possible to prevent the inconvenience of unintentionally opening the one-sided lid 7 by swinging the lock member 11.

  Furthermore, even when the unlocking member 12 is in the unlocking operation position, the single-opening bottle of this embodiment can prevent the unintentional opening of the single-opening lid 7 due to overturning or the like. That is, when the unlocking member 12 is in the unlocking operation position, as shown in FIG. 1, when the unlocking member 12 is in the locking position, the amount by which the operation part 124 protrudes outward from the surface of the protection member 51 is Smaller than. Therefore, even if the protruding operation part 124 is pressed due to the fall of the single-open bottle or contact with another, the engagement between the lock member 11 and the single-open lid 7 is not released. Therefore, the unintended opening of the single-open lid 7 is prevented, and the inconvenience that the beverage or the like in the bottle body 1 leaks can be prevented.

  Moreover, the single-open bottle of this embodiment can grasp | ascertain the locked state of the single-open lid 7 easily. That is, the surface of the portion above the operation portion 124 of the unlocking member 12 that protrudes and appears in the locking member 11 has a color different from that of the locking member 11 or a highly visible color such as a fluorescent color. Color. This makes it possible to prevent the colored part from appearing when locked and not appearing when unlocked. Thereby, it can be easily recognized whether or not the one-sided lid 7 is in a locked state depending on whether or not a colored portion appears.

  Further, in the present embodiment, by guiding the lock release member 12 in the inclined direction with respect to the lock member 11, the protruding amount of the operation portion 124 is formed smaller at the lock release operation position than at the lock position. However, you may adjust the protrusion amount from the surface of the protection member 51 of the operation part 124 by another method. For example, by making the surface shape of the protection member 51 protrude from the portion adjacent to the unlocking operation position of the operation unit 124 more than the portion adjacent to the lock position, the protrusion amount of the operation unit 124 is unlocked more than at the lock position. It is also possible to form a smaller one at the operation position. As such a locking mechanism, the one shown in FIGS. 7 and 8 can be considered.

  In FIG. 7, the locking mechanism 308 is configured by fitting the leg portion 312 d of the unlocking member 312 to the sliding window 341 formed in the locking member 311 so as to be slidable. On the shoulder member 305 side, a stopper 324 for locking the leg 312d is provided. The unlocking member 312 is slid in the direction of the arrow A from the solid line lock position when the operator's finger is hung on the operation unit 312a, and is operated to the unlocking operation position of the broken line. When pressed in the direction B, the one-sided lid 307 is unlocked. At the locked position of the unlocking member 312, the unlocking operation is prevented by the leg portion 312 d being engaged with the end face of the stopper 324.

  The lock mechanism 308 is configured so that the shape of the surface of the protection member 351 is closer to the operation portion 312a of the unlocking member 312 in the unlocking operation position than to the operation portion 312a of the unlocking member 312 in the locking position. Has a protruding shape. Thereby, the amount of protrusion at the unlocking operation position is smaller than the amount of protrusion at the lock position with respect to the amount of protrusion of the operation portion 312a from the surface of the protection member 351. Thereby, the operation part 312a of the unlocking member 312 in the unlocking operation position can be prevented from being opened by the operator when the single-opening lid 307 is not intended by being pressed by the fall of the single-opening bottle or the contact of other things. In FIG. 7, 342 is a tension spring provided between the unlocking member 312 and the locking member 311, and returns the unlocking member 312 released from the unlocking operation to the initial position, and 311 a is the locking member 311. Reference numeral 307b denotes an engaged portion of the single-open lid 307, reference numeral 321 denotes a compression spring that biases the lock member 311 toward the side where the lock member 311 engages the single-open lid 307, and reference numeral 323 denotes This is a rocking shaft of the lock member 311.

  On the other hand, FIG. 8 shows that the lock mechanism 408 is configured by slidably fitting the square shafts 412b projecting on both the left and right surfaces of the lock release member 412 into the hook-shaped guide groove 422 formed on the shoulder member 405 side. is doing. The back surface of the longitudinal portion of the guide groove 422 is a stopper surface 424 that is engaged with the square shaft 412b. The unlocking member 412 is slid in the direction of arrow A from the locked position of the solid line by the operator's finger being hung on the operation unit 412a, and is operated to the unlocking operation position of the broken line. When pressed in the direction B, the one-sided lid 407 is unlocked. At the locked position of the unlocking member 412, the unlocking operation is prevented by the square shaft 412b being engaged with the stopper surface 424.

  The lock mechanism 408 is configured so that the surface shape of the protective member 451 is closer to the operation portion 412a of the unlocking member 412 at the unlocking operation position than to the operation portion 412a of the unlocking member 412 at the locking position. Has a protruding shape. As a result, the amount of protrusion at the unlocking operation position is smaller than the amount of protrusion at the lock position with respect to the amount of protrusion of the operation portion 412a from the surface of the protection member 451. Thereby, the operation part 412a of the unlocking member 412 at the unlocking operation position can be prevented from being opened by the operator when the single-opening lid 407 is unintentionally pressed by the fall of the single-opening bottle or the contact of another object. In FIG. 8, 452 is a compression spring provided between the unlocking member 412 and the bottom of the storage chamber of the shoulder member 405, and returns the unlocking member 412 released from the unlocking operation to the initial position. Is an engaging portion of the lock member, 407 b is an engaged portion of the single-open lid 407, and 421 is a compression spring that urges the lock member 411 toward the side where the lock member 411 engages with the single-open lid 407. 423 is a rocking shaft of the lock member 411.

  By the way, the single-open bottle of this embodiment is comprised so that when a low temperature drink is accommodated in the bottle main body 1, it cools effectively and prevents generation | occurrence | production of condensed water. FIG. 6A is a bottom view showing the inside of the shoulder member 5 as viewed from the bottle body 1 side, and FIG. 6B is a three-side view showing the inner lid 56 attached to the shoulder member 5. is there. As shown in FIGS. 1 and 6A, the inner lid 56 is attached to the inner side of the top surface of the shoulder member 5 over a region on the back side of the drinking mouth 14. A ridge 56 a along the outer edge of the inner lid 56 is provided at a position slightly inside from the outer edge of the inner lid 56. A fitting recess 5a similar to the contour of the inner lid 56 is formed inside the top surface of the shoulder member 5, and the protrusion 56a of the inner lid 56 is fitted into the fitting recess 5a. The edge of the lid | cover 56 is being fixed to the inner surface of the fitting recessed part 5a by ultrasonic welding. Thus, a sealed air layer is formed between the fitting recess 5 a on the top surface of the shoulder member 5 and the inner lid 56.

  In the conventional single-open bottle, as shown in FIG. 9, a resin drinking mouth member 102 is attached to the mouth portion 101a of the bottle body 101, and the outside of the lower portion of the drinking mouth member 102 is surrounded and the drinking mouth 102a is viewed from above. A resin shoulder member 105 to be protruded is attached to the upper portion of the bottle body 101. On the top surface of the shoulder member 105, a one-sided lid 107 that covers the drinking mouth 102a is pivotally attached. Since the shoulder member 105 is only screwed to the resin-made annular edge member 108 fitted to the upper part of the bottle main body 101, water condensed on the surface of the drinking mouth member 102 is annularly connected to the shoulder member 105. There has been a problem in that it leaks to the outside through the threaded portion with the edge member 108.

  On the other hand, since the single-open bottle of this embodiment forms the air layer between the fitting recessed part 5a of the shoulder member 5, and the inner cover 56, the low temperature drink is accommodated in the bottle main body 1. Moreover, it can prevent that dew condensation arises on the surface of the shoulder member 5 by the heat insulation effect of the said air layer. Moreover, since this air layer is formed by fixing the inner lid 56 fitted in the fitting recess 5a of the shoulder member 5 by ultrasonic welding, it is possible to stably maintain a sealed state. Therefore, the effect of preventing condensation can be stably achieved over a long period of time. Further, since it is possible to prevent water and the like from entering the air layer, there is no need to wipe off the invading water.
