Description

  The present invention relates to a beverage container having a lock mechanism for fixing a lid that opens and closes a drinking mouth (or a spout).

  In recent years, with the growing awareness of hygiene, it has become common to bring water, tea, or juice drinks into water bottles and bring them to kindergartens, schools, workplaces, etc. Water bottles are a daily necessities used almost every day. It has become.

  In this way, the water bottle brought to the school or the like naturally needs to be sealed so that the beverage inside does not undesirably leak out. On the other hand, even if it is an infant, it is easy to drink. It is required to be able to open and close quickly with simple operation.

  In order to meet such a demand, a conventional water bottle 1 (for example, Patent Document 1) covers a main body 2 in which a beverage L is accommodated and a top surface opening 2a of the main body 2 as shown in FIG. An inner lid 4 having a drinking mouth 3, a one-sided lid body 5 pivotally mounted around a shaft 5 a provided at one end of the top surface of the inner lid 4, and the one-sided lid It is comprised with the lock mechanism 6 which fixes the cover body 5 in the closed state, and the top surface opening 3a of the drinking mouth 3 is formed inside the single-open cover body 5 with the single-open cover body 5 closed. A packing 7 that abuts and seals the inside of the water bottle 1 is provided.

  The lock mechanism 6 generally includes a lever 6a for fixing the single-open lid 5 in a closed state, a lock 6b for restricting the movement of the lever 6a, and a spring 6c for constantly urging the lever 6a in a direction to return the lever 6a to the fixed position. The lever 6a and the lock 6b are pivotally attached to the periphery of the inner lid 4 by shafts 6a1 and 6b1, respectively.

  According to this water bottle 1, when the single-open lid 5 is fixed in a closed state by the lock mechanism 6, the inside of the water bottle 1 is sealed by the packing 7 coming into contact with the top surface opening 3 a of the drinking mouth 3. Has been. When drinking the beverage L, the lock 6b in the lock mechanism 6 is rotated counterclockwise about the shaft 6b1, and the lever 6a is pushed against the urging force of the spring 6c while pushing the lower end of the lever 6a. 6a rotates counterclockwise about the shaft 6a1 and the fixing of the single-opening lid 5 is released. The drinking mouth 3 is exposed by opening the single-open lid 5 by rotating it clockwise in this released state.

  However, in the lock mechanism 6 of the water bottle 1, a spring 6c for returning the lever 6a for fixing the one-sided lid 5 to the fixed position is indispensable. Even if the lock 6b is omitted, at least the lever 6a Since it is necessary to provide the spring 6c, the number of parts cannot be further simplified and the cost cannot be reduced.

  Further, when the spring 6c is arranged inside the lever 6a, dust is easily collected in the spring 6c, and it is unsanitary, and the lock mechanism 6 is complicated so that dust and dirt are easily collected in the corner, and this is disassembled and cleaned. It was very difficult to do.

  Further, since the locking mechanism 6 is attached to the inner lid 4, when the one-sided lid body 5 is opened to drink a drink, the locking mechanism 6 hits the chin and gets in the way, or has dropped from the drinking mouth 3. As described above, when the beverage enters the lock mechanism 6, dust and dirt easily accumulate in the corners, and the lock mechanism 6 becomes unsanitary.

  The present invention has been developed in view of such problems of the prior art. Therefore, the main problem of the present invention is to reduce the cost by minimizing the number of parts, while being easy to disassemble and clean, clean to every corner, and to be used hygienicly. It is providing the drink container provided with the said locking mechanism.

According to the first aspect of the present invention, “the beverage storage space 23 is provided inside and the container body 12 having the drinking mouth 34 formed therein is connected via the hinge portion 36, and is rotated around the hinge portion 36. A lid 40 for opening and closing the drinking mouth 34;
A locking member 42 provided on the lid 40 and having an engaging protrusion 62 that engages with the lid fixing protrusion 38 of the container body 12 when the lid 40 is closed;
The lid 40 is provided with a lock member fitting notch 46 into which the locking member 42 is fitted by pivotally supporting the engaging protrusion 62 with respect to the lid fixing projection 38. And
One of a sliding projection 58 and an inclined surface 66 is provided on a surface of the lock member 42 adjacent to the lock member fitting notch 46,
The other of the sliding protrusion 58 and the inclined surface 66 is provided at a corresponding position of the locking member fitting notch 46.
The sliding protrusion 58 or the inclined surface 66 provided in the lock member fitting notch 46 is in sliding contact with the sliding protrusion 58 or the inclined surface 66 provided on the lock member 42 with elasticity. The locking mechanism 14 "of the beverage container 10" is characterized in that the engaging protrusion 62 is pressed and urged in a direction to engage with the lid fixing protrusion 38.

  According to the lock mechanism 14 of the present invention, the lock member 42 is fitted and pivotally supported in the lock member fitting notch 46 of the lid 40, and the lock member fitting notch 46 of the lock member 42. A sliding protrusion 58 (or inclined surface 66) is provided on the surface 54 adjacent to the inclined surface 66, and the inclined surface 66 (or sliding protrusion 58) is provided at a corresponding position of the lock member fitting notch 46. Is provided.

  In the following description, it is assumed that the sliding protrusion 58 is provided on the locking member 42 and the inclined surface 66 is provided on the locking member fitting notch 46, but in the opposite case (the inclined surface 66, Needless to say, the effects of the present invention can be obtained even when the sliding protrusion 58 is provided in the notch 46 for fitting the lock member.

  The inclined surface 66 provided in the locking member fitting notch 46 is in sliding contact with the sliding projection 58 provided on the locking member 42 with elasticity, and the engaging projection 62 provided on the locking member 42 is placed in the container. The main body 12 is pressed and urged in a direction to be engaged with the lid fixing projection 38.

  Thus, in a state where the drinking mouth 34 is closed with the lid body 40 rotated about the hinge portion 36, the engaging protrusion 62 is connected to the lid body fixing projection 38 by the pressing biasing force from the inclined surface 66. The engaged state is maintained.

  When opening the lid 40, the locking member 42 is applied in a direction in which the engaging projection 62 is disengaged from the lid fixing projection 38 against the pressing biasing force from the inclined surface 66 by applying an external force. In this state, the lid 40 is rotated around the hinge portion 36, so that the drinking mouth 34 of the container body 12 is exposed.

  Since the relationship between the inclined surface 66 and the sliding projection 58 is in a sliding contact state with elasticity, when the lock member 42 is rotated, the lock member insertion notch portion 46 becomes the sliding projection 58 of the lock member 42. Therefore, the lock member fitting cutout 46 is added with an elastic force to return to the original shape to the pressing biasing force from the inclined surface 66.

  For this reason, by loosening the force applied from the outside, the lock member 42 is immediately rotated back in the direction (that is, the direction in which the engaging protrusion 62 is engaged with the lid fixing protrusion 38).

  As described above, according to the lock mechanism 14 of the present invention, the lock member 42 rotated by applying a force from the outside can be returned to the original position using the elastic force of the lid 40 itself. Therefore, it is not necessary to provide a spring material or other elastic members, and not only can the number of members be reduced, but also the structure is simplified and easily disassembled, and dust and dirt are not easily collected.

  Further, in the lock mechanism 14 of the present invention, since the lock member 42 is attached to the lid body 40, the lock member 42 does not get in the way when the lid body 40 is opened to drink the beverage L inside. Furthermore, even if the beverage L hangs down from the drinking hole 34, the beverage L does not enter the lock mechanism 14.

  The “drinking mouth 34” is not limited to a slightly small-diameter opening for the user to directly drink and drink the beverage L, but a slightly large-diameter opening (pouring spout) for the user to pour the beverage L into the cup. It is a concept that naturally includes. In addition, the “beverage container 10” is a concept including a small portable type that is carried by a person such as a water bottle, a larger type, and a stationary type. These are the same throughout this specification.

According to the second aspect of the present invention, the lock mechanism 14 of the first aspect fixes the lid body 40 to the hinge portion 36, the lock member 42, and the container body 12. In relation to the locking mechanism 14 that fixes the lid body 40 with the lock member 42, “the lid body 40 covering the drinking mouth 34 provided in the container body 12 having the beverage housing space 23 therein,
A plurality of locking members 42 provided on the lid 40 and having engaging protrusions 62 that engage with the lid fixing protrusions 38 of the container body 12 when the lid 40 is covered;
A plurality of locking member fitting notches 46 into which the locking member 42 is fitted, with the engaging protrusion 62 pivotally supported on the lid fixing protrusion 38 so that the engaging protrusion 62 can be engaged and disengaged. Is provided,
One of a sliding protrusion 58 and an inclined surface 66 is provided on a surface of the plurality of lock members 42 adjacent to the lock member fitting notch 46, respectively.
The other of the sliding projection 58 and the inclined surface 66 is provided at a corresponding position of the plurality of locking member fitting notches 46,
The sliding protrusion 58 or the inclined surface 66 provided in the lock member fitting notch 46 is in sliding contact with the sliding protrusion 58 or the inclined surface 66 provided on the lock member 42 with elasticity. The locking mechanism 14 "of the beverage container 10" is characterized in that the engaging protrusion 62 is pressed and urged in a direction to engage with the lid fixing protrusion 38.

  According to the locking mechanism 14 of the present invention, when the lid 40 is removed from the container main body 12, an external force is applied to all the locking members 42 so that the engaging projections 62 are separated from the lid fixing projection 38. The lock member 42 is rotated in the direction of disengagement, and the lid 40 of the container body 12 is exposed by removing the lid 40 from the container body 12 in this state. The principle of returning the individual lock members 42 to their original positions by loosening the externally applied force is the same as in the case of claim 1.

  The invention described in claim 3 relates to the lock mechanism 14 according to claim 1 or 2, wherein “the lock member 42 or the lid 40 has the lock member 42 until the sliding protrusion 58 is separated from the inclined surface 66. A stopper 64 is provided to restrict the rotation of 42 ".

  When the external force is applied to the lock member 42 vigorously, the sliding projection 58 is separated from the inclined surface 66 and cannot receive the pressing biasing force from the inclined surface 66. Although the lock member 42 may not return to its original position even if it is loosened, the stopper 64 is provided in the lock mechanism 14 of the present invention, so that the sliding projection 58 is prevented from being separated from the inclined surface 66. Even if the external force is applied vigorously, the lock member 42 always returns to the original position if the force is loosened.

  The invention described in claim 4 relates to the lock mechanism 14 according to any one of claims 1 to 3, “A force is applied to the lock member 42 or the lid 40 from the outside to the lock member 42. A reverse rotation restricting stopper 60 for restricting excessive rotation of the lock member 42 in the direction in which the engaging protrusion 62 is engaged with the lid fixing protrusion 38 in the absence of the engaging protrusion 62 is provided. It is characterized by.

  The sliding protrusion 58 provided on the lock member 42 is “in the direction in which the engaging protrusion 62 is engaged with the lid fixing protrusion 38” from the inclined surface 66 provided on the lock member fitting notch 46. Therefore, the lock member 42 may be excessively rotated in the same direction when no force is applied to the lock member 42 from the outside. Since the rotation restricting stopper 60 is provided, such excessive rotation can be prevented.

  In addition, when no external force is applied to the lock member 42, the lock member 42 is pressed against the lock member insertion notch 46 via the reverse rotation restricting stopper 60 by the pressing biasing force from the inclined surface 66. Therefore, even when the lock mechanism 14 is vibrated, there is no possibility that the lock member 42 vibrates and an unpleasant sound is generated.

  The invention described in claim 5 is “a beverage container 10 including the lock mechanism 14 according to any one of claims 1 to 4”.

  As described above, according to the present invention, by minimizing the number of parts, the cost can be reduced, and the beverage container locking mechanism that can be easily disassembled and cleaned and used hygienically, and the locking mechanism. It was possible to provide a beverage container comprising:

FIG. 4 is a (a) perspective view and a (b) left side view showing a lock member in the lock mechanism of the present invention. It is sectional drawing which shows the movement of the locking member in the locking mechanism of this invention. FIG. 4 is a cross-sectional view taken along line VV in FIG. 4, showing a state in which the lock member insertion recess is expanded when the lock member rotates and the sliding protrusion slides on the tapered bottom surface of the sliding recess. is there. It is a figure which shows a prior art.

  Hereinafter, an embodiment of a beverage container (water bottle) 10 to which the present invention is applied will be described with reference to the drawings. As shown in FIG. 1, the beverage container 10 of the present embodiment generally includes a container body 12, a lock mechanism 14, a cup 16 and a belt 18 provided as necessary.

  The container main body 12 includes a bottomed cylindrical container cylinder 20 and an inner lid 22 that closes the top opening 20a of the container cylinder 20. The internal space 20b of the container cylinder 20 closed by the inner lid 22 serves as a beverage storage space 23 for storing a beverage L such as water, tea, or juice. Of course, the container main body 12 may be formed as a single unit without being separated from the container cylinder 20 and the inner lid 22. In this case, the beverage L is taken in and out through the mouth 34 described later.

  The container cylinder 20 is formed of a resin typified by polypropylene (of course, the material is not limited to this, and a watertight material such as a metal such as stainless steel can be used in addition to the resin. The same applies to the materials of the other members.) A male screw 24 for screwing the inner lid 22 is formed on the outer periphery of the upper end. A pair of belt mounting projections 26 for mounting the belt 18 to the container tube 20 are provided in a horizontal outward direction at a position that does not interfere with the inner lid 22 slightly below the male screw 24.

  The inner lid 22 is made of resin in the same manner as the container tube 20, and a female screw 28 for inserting and screwing the upper end portion of the container tube 20 is formed inside the lower end portion thereof. Further, a ring-shaped packing 29 is disposed on the back side of the female screw 28, and a male screw 30 to which the cup 16 is screwed is formed on the outer surface above the female screw 28. Yes.

  Moreover, the base part 31 which has the base surface 31a parallel to the said top surface 22a is formed in the top | upper surface 22a of the inner lid | cover 22, and the position of the inner lid | cover 22 is located in the position which approached a little periphery from the center part of the base surface 31a. A through-hole 32 that communicates the inside and the outside is formed, and a cylindrical drinking mouth 34 protrudes upward so as to surround the through-hole 32.

  Further, a hinge portion 36 for attaching a lid body 40 (described later) of the lock mechanism 14 to the inner lid 22 so as to be rotatable is formed on the peripheral edge of the base surface 31a opposite to the direction in which the drinking mouth 34 approaches. A hinge female portion 36a as a member is formed. Further, a lid fixing projection 38 that engages with the lock mechanism 14 is provided in a horizontal direction from the base surface 31a on the peripheral side further than the drinking mouth 34 in the direction in which the drinking mouth 34 approaches.

  As shown in FIG. 2A, the lock mechanism 14 includes a lid body 40, a lock member 42, and a valve body 44 provided as necessary.

  As shown in FIGS. 2A to 2D, the lid 40 is a member for opening and closing the drinking mouth 34 provided in the inner lid 22 constituting the container body 12, and includes the top surface 40a and the top surface 40a. It has a side wall 40b extending downward from the periphery of the top surface 40a and an internal space 40c surrounded by the top surface 40a and the side wall 40b. Further, when viewed from the side (see FIG. 2A), the lid 40 is formed such that one end side (left side in the figure) is low and the other end side (right side in the figure) is high. A hinge male portion 36b that constitutes the hinge portion 36 is formed with the hinge female portion 36a of the inner lid 22 at one lower end. Furthermore, a lock member fitting notch 46 into which the lock member 42 is fitted is formed at the other end of the tall.

  The lid body 40 is not limited to the “single-opening” system as in the present embodiment, but instead of the hinge portion 36, another lock member 42 is attached, and both the lock members 42 are removed at once, thereby the lid body 40. May be separated from the inner lid 22.

  Further, an elastic member such as a spring that urges the lid 40 in the opening direction may be attached to the hinge portion 36. Thereby, the lid 40 can be automatically opened only by operating the lock member 42.

  When the lock member fitting notch 46 is viewed from the front (see FIG. 2C), the lower side (that is, the container body 12 side when the lid 40 is attached to the container body 12) is opened. It has an inverted U-shape, and a turning recess 48 and a sliding recess 50 are formed on the inner surface 46a of the lock member fitting notch 46 (a surface adjacent to the fitted lock member 42). Yes. Of course, the notch portion 46 for fitting the lock member is not limited to an inverted U shape, and may be a U shape with an opening on the upper side, or an external force required to rotate the lock member 42 increases. It may be O-shaped without any. A detailed description of the recesses 48 and 50 will be given below together with the description of the lock member 42.

  The lock member 42 is a resin member for fixing the lid body 40 to the inner lid 22 of the container body 12 in a state where the drinking mouth 34 is closed in cooperation with the hinge portion 36, as shown in FIG. A rectangular plate-shaped main body member 52 with rounded four corners, a pair of plates 54 extending in the vertical direction from both long side ends of the main body member 52, and three sets protruding outward from the plate 54 Projections (a pair of turning projections 56, a pair of sliding projections 58, and a pair of reverse rotation regulating stoppers 60) and a lower short side of the main body member 52 (on the container body 12 side close to the sliding projections 58). Similar to the plate 54, the projection 62 for engagement projecting from the main body member 52 in the vertical direction from the end on the short side), and the short side on the upper side opposite to the short side on which the projection for engagement 62 projects. At the edge of the side (short side near the reverse rotation restricting stopper 60) Te is integrally formed with a stopper 64 which projects perpendicularly from the body member 52.

  The rotation protrusion 56 protrudes outward from the plate 54 at the longitudinal central portion of the main body member 52 of the lock member 42, and the lock member 42 is fitted into the lock member fitting notch 46 of the lid body 40. At this time, the rotation protrusion 56 of the lock member insertion notch 46 is fitted from the inside of the lid body 40 (in this embodiment, the rotation protrusion 56 is formed into the rotation recess 48. A rotation protrusion insertion groove 48a shallower than the rotation recess 48 is formed from the rotation recess 48 to the inner end of the lock member insertion notch 46 so as to be easily fitted. As a result, as shown in FIG. 4, the lock member 42 rotates around the rotation protrusion 56 within the lock member fitting notch 46, and engages with the engagement protrusion 62 with respect to the lid fixing protrusion 38. Is supported so that it can be engaged and disengaged. The lock member 42 only needs to be pivotally supported so that the engaging projection 62 can be engaged and disengaged with respect to the lid fixing projection 38, and the pivot support means includes the pivot projection 56 and the pivot recess 48 described above. It is not limited to.

  The sliding projection 58 protrudes outward from the plate 54 on the lower short side (that is, the inner lid 22 side) of the rotation projection 56, and the lock member 42 is used for fitting the lock member 42. When fitted into the notch 46, the lock member is fitted into the sliding recess 50 of the lock member fitting notch 46 from the inside of the lid 40. In addition, the shape of the sliding projection 58 is a trapezoid whose bottom is located on the lower short side (the container body 12 side) in plan view.

  As shown in FIG. 5, the sliding recess 50 has an inclined surface 66 formed so that the sliding recess 50 becomes shallower from the inside to the outside of the lid 40. The front end of the sliding projection 58 fitted is in contact with the inclined surface 66. In this embodiment, the inclined surface 66 is formed at the bottom of the sliding recess 50, but does not include such a sliding recess 50, and is a surface adjacent to the lock member 42 of the lock member fitting notch 46. The inclined surface 66 may be formed to project from 46a.

  As shown in FIG. 5, the relationship between the sliding projection 58 and the inclined surface 66 is that the distance between the surfaces 46a adjacent to the lock member 42 on which the inclined surface 66 is formed from the distance Y between the tips of the sliding projections 58. The lock member 42 is turned in the unlocking direction from the place where the lid 40 in which X is narrow and the lock member fitting notch 46 is made of an elastic resin (or metal which can be elastically deformed) is also possible. When this is done, the notch 46 for inserting the lock member is pushed and widened by the sliding projection 58, and the reaction force pushes the sliding projection 58 back along the inclined surface 66 and pushes the lock member 42 back in the locking direction. . When the lock member fitting notch 46 has a U-shaped notch shape, the above-described springiness is noticeable.

  As shown in FIG. 3, the reverse rotation restricting stopper 60 protrudes outward from the plate 54 on the short side above the rotation protrusion 56 (that is, the end opposite to the container body 12 side). The locking member 42 is fitted into the locking member fitting notch 46, and the pushing force is applied to the end of the locking member 42 opposite to the container main body 12 (hereinafter referred to as “unlocking end A”). Is not urged (in a state where the surface of the main body member 52 in the lock member 42 is flush with the lock member fitting notch 46 as shown by a one-dot chain line in FIG. 4). The lid 40 abuts on the inner side (the inner end of the lock member fitting notch 46). Of course, the reverse rotation restricting stopper 60 is provided inside the lid body 40 so that the reverse rotation restricting stopper 60 restricts the rotation of the lock member 42 in a state where the pushing force is not biased to the unlocking end A. It may be.

  The engaging protrusion 62 (see FIG. 3) engages with the lid fixing protrusion 38 provided on the inner lid 22 when the lid 40 is rotated about the hinge portion 36 and the drinking hole 34 is closed. By doing this, the lid 40 is fixed to the inner lid 22.

  When the lock release end A of the lock member 42 is pushed in, the stopper 64 comes into contact with the inner surface of the lid body 40 before the sliding projection 58 is separated from the inclined surface 66, so that the lock member 42 is further rotated. It is a member that regulates Similarly to the reverse rotation restricting stopper 60, the stopper 64 is provided on the inner side of the lid body 40, and comes into contact with the lock member 42 before the sliding projection 58 is separated from the inclined surface 66 to restrict the rotation of the lock member 42. You may do it.

  In the case of the present embodiment, the stopper 64 is, as described above, the upper short side (the short side closer to the reverse rotation restricting stopper 60) on the side opposite to the short side on which the engaging protrusion 62 is projected. As shown in FIG. 4, it projects from the side end portion in a direction perpendicular to the main body member 52, and locks by contacting the inner side surface of the stepped portion 40 d formed on the top surface 40 a of the lid body 40. Unnecessary rotation of the member 42 is restricted. Of course, the rotation restricting means by the stopper 64 is not limited to this.

  In the present embodiment, the sliding projection 58, the reverse rotation restricting stopper 60, and the stopper 64 are each formed as a pair. However, even if only one of them is formed, the effect of the present invention can be obtained. it can.

  As shown in FIGS. 2A and 4, the valve body 44 is formed of an elastic body (for example, silicon resin) that is softer than the lid body 40 and the like, and inside the top surface 40 a of the lid body 40. When the lid 40 is fixed to the inner lid 22, the lid 40 is attached to a position that closes the tip opening of the drinking mouth 34.

  In the case of the present embodiment, the valve body 44 is configured by a bowl-shaped main body portion 70 having an inner space 68 and a projecting portion 72 projecting outward from the central portion of the main body portion 70. The inner space 74 of the installation portion 72 communicates with the inner space 68 of the main body portion 70, and a thin slit hole 76 that is cut with a cutter knife, for example, at the tip of the projection portion 72. Is formed.

  The main body 70 is formed in a step shape, and a cylindrical inner protrusion 77 projects toward the inner space 68 on the inner surface of the step closer to the protrusion 72, and the valve The top surface 40 a of the lid body 40 to which the body 44 is attached has a lid body communication hole 78 for communicating the outside of the lid body 40 and the inner space 68 of the valve body 44 attached to the inner surface of the lid body 40. A cylindrical body 79 is formed on the inner side of the top surface 40a so as to surround the lid communication hole 78.

  The valve body 44 is fixed to the lid body 40 by fitting the cylindrical body 79 between the inner protrusion 77 of the valve body 44 and the stepped portion inner wall 70 a of the main body 70.

  Here, when the external pressure in the vicinity of the slit hole 76 is higher than the pressure in the inner spaces 68, 74, that is, when external air tries to flow into the inner spaces 68, 74 through the slit hole 76, The slit hole 76 is closed when the tip end portion of the installation portion 72 is squeezed, and the inner space 74 and the outside are not in communication (the pressure in the inner spaces 68 and 74 and the external pressure in the vicinity of the slit hole 76 are reduced). Even in the case where they are equal, the slit hole 76 is thin, so that it is almost in a non-communication state.)

  Conversely, when the external pressure in the vicinity of the slit hole 76 is lower than the pressure in the inner spaces 68 and 74, that is, when the air in the inner spaces 68 and 74 tries to flow to the outside through the slit hole 76, The slit hole 76 is opened by the bulging of the tip of the installation portion 72, and the inner space 74 and the outside are in communication with each other.

  Therefore, as shown in FIG. 4, when the valve body 44 closes the opening of the drinking mouth 34, the internal pressure of the beverage storage space 23 of the container body 12 decreases (for example, drinks hot tea After pouring into the storage space 23 and immediately closing the drinking mouth 34 with the valve body 44, the air in the beverage storage space 23 contracts as the tea cools.), The beverage storage space 23 and the outside (lid When the pressure difference with the inner space 68, 74) of the valve body 44 communicated through the lid body communication hole 78 provided in the body 40 increases to a certain extent, the tip of the projecting portion 72 of the valve body 44 swells. Thus, the slit hole 76 is opened. Thereby, since air flows into the beverage storage space 23 from the outside, the pressure in the beverage storage space 23 is undesirably lowered, so that the valve body 44 sticks to the opening of the drinking mouth 34, and the lid 40 is removed. It is possible to avoid the possibility that the valve body 44 is detached from the lid body 40 when the cover body 40 is opened and the valve body 44 is lost.

  As shown in FIG. 1, a female screw 80 is formed inside the opening of the cup 16, and the male screw 30 formed on the inner lid 22 can be made to face the opening downward. Yes. Moreover, you may provide the handle 82 as needed.

  The belt 18 is used when the beverage container 10 is hung from the shoulder. The belt body 84 is made of polyester, the hanger 86 attached to both ends of the belt body 84, and the length of the belt body 84. It is comprised with the adjustment buckle 88 to adjust. When using the belt 18, the lifting tool 86 is attached to the belt attachment protrusion 26 formed on the container cylinder 20.

  The procedure for assembling the beverage container 10 of the present embodiment will be briefly described. First, the inner lid 22 is screwed to the container cylinder 20 via the packing 29 (if the beverage L is put in the container cylinder 20 first). Good.) Next, the lock member 42 is attached to the notch 46 for fitting the lock member of the lid 40, and the valve body 44 is attached to the lid 40. After that, the hinge male portion 36 b of the lid 40 is attached to the inner lid 22. The hinge portion 36 is formed by engaging with the formed hinge female portion 36 a, and the lid body 40 is attached to the inner lid 22. Finally, the beverage container 10 is completed by attaching the cup 16 and the belt 18 as necessary.

  When drinking the beverage L in the beverage container 10, the cup 16 is removed, and then the lock release end A of the lock member 42 is pushed, so that the lock member 42 rotates about the rotation projection 56, The joint projection 62 is disengaged from the lid fixing projection 38 on the side of the inner lid 22 and the fixing of the lid 40 is released. After releasing the fixing of the lid body 40, when the lid body 40 is rotated around the hinge portion 36, the drinking mouth 34 is exposed, so that the beverage L can be taken (of course, the beverage L can be placed on the removed cup 16). May be poured.)

  According to the locking mechanism 14 applied to the beverage container 10 of the present embodiment, when the unlocking end portion A of the locking member 42 is pushed in, as shown in FIG. The sliding projection 58 provided on the lock member 42 also rotates while being removed from the portion 38, but the inclined surface 66 with which the sliding projection 58 abuts is formed from the inside of the lid 40 as shown in FIG. It is formed so as to become shallower toward the outside, and is in sliding contact with the sliding projection 58 and presses and biases the engaging projection 62 in a direction to engage with the lid fixing projection 38. The sliding projection 58 slides on the inclined surface 66 from the inner side to the outer side of the lid body 40, so that the container body 12 side (open side) of the lock member fitting notch 46 is the outer side. To be spread.

  When the notch 46 for inserting the lock member is pushed outward, the lid 40 is made of resin (or may be an elastically deformable metal). The lock member is inserted based on the elastic force of the lid 40 itself. A stress is generated in a direction to close the notch 46. For this reason, when the force for pushing the unlocking end A is loosened, the container body 12 side of the lock member fitting notch 46 is closed, and at the same time, the lock member 42 also has its sliding projection 58 on the inclined surface 66. It is rotated in the direction in which it is pushed and immediately returns (that is, the direction in which the engaging protrusion 62 engages with the lid fixing protrusion 38).

  As described above, according to the lock mechanism 14 of the present embodiment, the lock member 42 rotated by pushing in the unlocking end A is returned to the original position using the elastic force of the lid 40 itself. Therefore, it is not necessary to provide a spring material or other elastic members.

  Further, in the lock mechanism 14 of the present embodiment, since the lock member 42 is attached to the lid body 40, the lock member 42 may become an obstacle when the lid body 40 is opened and the beverage L inside is drunk. Furthermore, even if the beverage L hangs down from the drinking mouth 34, the beverage L does not enter the lock mechanism 14.

  In addition, the lock mechanism 14 of the present embodiment is provided with a stopper 64 that restricts the rotation of the lock member 42 so that the sliding projection 58 is separated from the inclined surface 66. For this reason, even if the unlocking end A of the lock member 42 is pushed in vigorously, the lock projection 42 returns to the original position even if the pushing force is loosened by separating the sliding projection 58 from the inclined surface 66. If the pushing force is loosened, the lock member 42 will always return to its original position.

  Further, even when the pushing force is not urged to the unlocking end A of the lock member 42, the inclined surface 66 of the lock member fitting notch 46 is in sliding contact with the sliding projection 58, and the engaging projection 62. Is pressed and urged in a direction to engage with the lid fixing protrusion 38, but the reverse rotation restricting stopper 60 abutting on the inside of the lid 40 on the lock release end A side of the lock member 42. Therefore, it is possible to prevent the lock member 42 from excessively rotating in the direction in which the engagement protrusion 62 is engaged with the lid fixing protrusion 38.

  In addition, when no external force is applied to the lock member 42, the lock member 42 is pressed against the lock member insertion notch 46 via the reverse rotation restricting stopper 60 by the pressing biasing force from the inclined surface 66. Therefore, even when the lock mechanism 14 is vibrated, there is no possibility that the lock member 42 vibrates and an unpleasant sound is generated.

  In the above embodiment, the locking member 42 is provided with the sliding protrusion 58 and the locking member fitting notch 46 is provided with the inclined surface 66, but conversely, the locking member 42 protrudes the inclined surface 66. The sliding protrusion 58 may be formed in the notch 46 for inserting the lock member.
