  The present invention relates to a stopper.

  In the past, when the operating part is moved toward the rotating shaft against the biasing force of the coil spring, the locking claw moves toward the rotating shaft in conjunction with the movement of the operating part and There has been proposed a “plug body in which the locking claws are unlocked” (for example, see Japanese Patent No. 4736133).

Japanese Patent No. 4736133

  By the way, when the beverage container is assembled by mounting the above-described plug body on the container as the plug body of the beverage container, the user of the beverage container is usually on the opposite side of the rotation axis of the beverage container. In this way, the operation part is operated by holding the beverage container. That is, the user releases the lock by sliding the operation unit from the near side to the far side. However, it is imagined that some beverage container buyers do not like the operation of sliding the operation unit from the near side to the far side in this way. In the past, various plug bodies having locking mechanisms other than the above-described locking mechanisms have been proposed, but it is assumed that there are some who do not like the operation of releasing the locking of these plug bodies. Therefore, it seems that there are not a few who are waiting for a plug having a locking mechanism that has not been proposed to date.

  An object of the present invention is to provide a plug having a locking mechanism that has not been proposed until now, and to meet the demands of those who are waiting for such a plug.

A plug according to one aspect of the present invention includes a plug body, a rotation opening / closing mechanism, a lid, and a locking member. The plug body has a liquid passage and a locking claw receiving portion. The liquid passage extends in the vertical direction and opens on both the upper and lower sides. The latching claw receiving portion receives a later-described engaging claw portion so as to be freely inserted and removed. The rotation opening / closing mechanism is disposed on the rear side of the plug body. The lid is attached to the plug body via a rotation opening / closing mechanism. A locking member has a main-body part and a latching claw part . The engaging claw portion protrudes inward from the back side surface of the front wall portion of the main body portion. And this latching member latches a cover body to a stopper main body. And the main-body part of this latching member cancels | releases the latching | locking of the cover body with respect to a stopper main body by slidingly moving toward the front diagonally upward in side view.

  By the way, when the stopper according to the present invention is attached to a container as a stopper for a beverage container to obtain a beverage container, the user of the beverage container is usually opposite to the stopper opening / closing mechanism (rotating shaft). The container is gripped so that the side is in front, and the locking member (operation unit) is operated. That is, the user slides the locking member (operation unit) diagonally forward and upward in a side view when releasing the locking of the lid body with respect to the plug body. As far as the inventors of the present application know, no plug having such a locking mechanism has been proposed to date. Therefore, according to the present invention, it is possible to meet the demands of those who wait for such a plug.

In the plug body described above, it is preferable that the plug body further has a standing wall portion. The standing wall portion is formed above the opening on the upper side of the liquid passage. Moreover, it is preferable that the latching claw receiving part is formed on both the left and right sides of the standing wall part.

Moreover, it is preferable that the above-described plug body further includes an urging member. The urging member urges the main body of the locking member toward the rotation opening / closing mechanism. This locking member is attached to the lid via an urging member.

A plug according to another aspect of the present invention includes a plug body, a rotation opening / closing mechanism, a lid, a locking member, and an urging member. The plug body has a locking claw receiving portion. The latching claw receiving portion receives a later-described engaging claw portion so as to be freely inserted and removed. The rotation opening / closing mechanism is disposed on the rear side of the plug body. The lid is attached to the plug body via a rotation opening / closing mechanism. A locking member has a main-body part and a latching claw part. The engaging claw portion protrudes inward from the back side surface of the front wall portion of the main body portion. And this latching member latches a cover body to a stopper main body. Moreover, this locking member is attached to the lid body via an urging member. The urging member urges the main body of the locking member toward the rotation opening / closing mechanism. And the main-body part of this latching member cancels | releases the latching | locking of the cover body with respect to a stopper main body by slidingly moving toward the front diagonally upward in side view.

By the way, when the stopper according to the present invention is attached to a container as a stopper for a beverage container to obtain a beverage container, the user of the beverage container is usually opposite to the stopper opening / closing mechanism (rotating shaft). The container is gripped so that the side is in front, and the locking member (operation unit) is operated. That is, the user slides the locking member (operation unit) diagonally forward and upward in a side view when releasing the locking of the lid body with respect to the plug body. As far as the inventors of the present application know, no plug having such a locking mechanism has been proposed to date. Therefore, according to the present invention, it is possible to meet the demands of those who wait for such a plug.

  The cylindrical wall 111 has a cylindrical shape. The internal space 111a of the cylindrical wall portion 111 functions as a fluid passage through which a beverage flowing from the container 200 (described later) toward the semi-filled wall portion 114 passes.

  As shown in FIG. 2, the male screw portion 112 is formed on the outer peripheral surface of the lower portion of the cylindrical wall portion 111, and is formed on the inner peripheral surface of the opening 210 of the container 200 (described later). It can be screwed with the portion 211 (see FIG. 11). Further, as shown in FIGS. 2 and 9, a packing 119 is detachably attached under the male screw portion 112.

  As shown in FIG. 9, the semi-cylindrical wall portion 114 is disposed on the opposite side of the cylindrical wall portion 111 from the male screw portion forming side, that is, on the cylindrical wall portion 111. In plan view, the semicircular portion of the semi-saddle wall portion 114 is disposed on the opposite side of the hinge mechanism portion 140, that is, on the front side of the plug body 100, and the straight portion is disposed on the hinge mechanism portion side, that is, on the back side. Yes. Further, as shown in FIGS. 5 and 9, a through hole 113 is formed in the bottom portion of the half walled wall portion 114. As a result, the internal space 114a of the semi-cylindrical wall portion 114 communicates with the internal space 111a of the cylindrical wall portion 111 through the through hole 113 (see FIG. 9).

  The standing wall 115 has a substantially half-moon shape in plan view (see FIG. 5). In plan view, the semicircular portion of the standing wall portion 115 is disposed on the opposite side of the hinge mechanism portion 140, that is, on the front side of the plug body 100, and the linear portion is disposed on the hinge mechanism portion side, that is, on the back side. Further, the standing wall portion 115 is inclined downwardly from the opposite side of the hinge mechanism portion side to the hinge mechanism portion side in a side view (see FIG. 6). That is, the standing wall portion 115 is high on the side opposite to the hinge mechanism portion side (that is, the front side of the plug body 100) and becomes lower toward the hinge mechanism portion side, that is, the back surface side. And the latching nail | claw receiving part 115b is formed in the both sides of this standing wall part 115 as FIG. 5 and FIG. 6 shows. A pair of locking claws 133 to be described later are inserted into these locking claw receiving portions 115b in a freely detachable manner. Further, an arc portion (hereinafter referred to as “standing wall central portion”) 115a sandwiched between the locking claw receiving portions 115b of the standing wall portion 115 is used as a drinking mouth. Further, as shown in FIG. 5, the locking claw receiving portion 115 b swells toward the through hole 113. Therefore, the beverage from the through hole 113 toward the semicircular portion of the standing wall 115 is rectified by the locking claw receiving portion 115b toward the standing wall central portion 115a.

(2) Lid The lid 120 is mainly composed of a lid main body 121, a lid cover 122, an elastic protrusion 123, a pair of connecting pieces 142, and a locking member 130, as shown in FIGS. The

(2-1) Lid Body As shown in FIG. 5, the lid body 121 has a substantially D shape (circular slice shape) in plan view. When the plug body 100 is in a closed state, the arc portion of the lid main body 121 is located on the opposite side of the hinge mechanism section side, that is, the front side of the plug body 100, and the straight line section is on the hinge mechanism section side. That is, it is located on the back side. Although not shown, the top wall portion of the lid main body 121 is inclined downwardly from the opposite side of the hinge mechanism portion side to the hinge mechanism portion side in a side view, and the standing wall portion 115 is substantially free of gaps. Covering. Further, the side wall portion of the lid main body 121 surrounds the standing wall portion 115 with almost no gap in plan view. In addition, a pair of windows (see FIG. 7) is formed in the arc portion of the lid main body 121. A locking claw 133 of a locking member 130, which will be described later, is inserted into the window from the outside toward the inside.

(2-2) Lid Cover The lid cover 122 has a substantially H shape in plan view, and covers a part of the upper surface, a part of the side surface of the lid body 121, and a side surface of the hinge mechanism part 140. In plan view, a part of the locking member 130 is accommodated in the recess on the front side of the lid cover 122, and a part of the hinge mechanism part 140 is accommodated in the recess on the back side of the lid cover 122.

(2-3) Elastic Protrusion Part The elastic protrusion part 123 is formed from an elastic material such as rubber or elastomer, and protrudes from the vicinity of the approximate center on the back side of the lid main body 121 as shown in FIG. The elastic projection 123 is formed when the locking claw 133 is inserted into the locking claw receiving portion 115b, that is, when the lid 120 is closed, as shown in FIGS. The through hole 113 is closed.

(2-4) Connection Piece The connection piece 142 is formed at the rear end of the lid main body 121 and constitutes the hinge mechanism part 140 together with the hinge connection part 141 of the lower exterior member 150 as described later. The connecting piece 142 has a through hole through which a hinge pin (not shown) is inserted.

(2-5) Locking member As shown in FIGS. 1, 5, and 9, the locking member 130 mainly includes a main body 131, an operation recess 132, a locking claw 133, and a locking claw biasing mechanism. (Not shown).

  The main body 131 has a gate shape in a front view and a shape in which one side of a square is replaced with an arc in a plan view. By the way, in the front view, a part of the lid main body 121 is exposed under the center of the main body 131 (see reference numeral 121a). The exposed portion 121a is assumed to be used as a support portion when the user pulls the locking member 130 on the side opposite to the hinge mechanism portion side (that is, the front side). The main body 131 can move back and forth along the top wall of the lid main body 121. That is, the main body 131 can move back and forth along a direction substantially parallel to the upper edge of the standing wall 115 in a side view. More specifically, when the locking of the lid 120 to the plug body 110 is released, the main body 131 moves obliquely upward in a side view, and the lid 120 is locked to the plug body 110. The main body 131 moves obliquely downward in a side view. When the locking claw 133 is inserted into the locking claw receiving portion 115 b, that is, when the lid 120 is locked to the plug body 110, the top surface and the outer peripheral surface of the main body 131, the lid main body 121. There are no steps on the top surface and the outer peripheral surface of the exposed portion 121a and the lid cover 122, and a smooth flat surface and a curved surface are formed on the lid 120 (see FIG. 1). On the other hand, when the latching claw 133 is pulled out from the latching claw receiving portion 115b, that is, when the lid 120 is released from the stopper main body 110, the top surface and the outer peripheral surface of the main body 131 are covered with the lid. The exposed portion 121a of the main body 121 and the top surface and the outer peripheral surface of the lid cover 122 protrude above and on the front surface side. There will be a difference in level between the top surface and the outer peripheral surface (see FIG. 4).

  As shown in FIGS. 1 and 9, the operation recess 132 is located at a substantially central portion of the plug body 100 in a plan view. And this operation recessed part 132 is formed from the side wall part 132a and the inclination wall part 132b. The side wall part 132a functions as a power point part when the locking member 130 is moved to the front side. When the locking member 130 is moved to the front side, a locking claw 133 described later is pulled out from the locking claw receiving portion 115b, and the locking of the lid 120 with respect to the plug body 110 is released.

  As shown in FIG. 5, the locking claws 133 protrude inward from the back side surfaces of the left and right front walls of the main body 131. Further, as described above, the locking claws 133 are inserted through a pair of windows provided in the arc portion of the lid main body 121 so as to be able to appear and retract (see FIG. 5).

  The locking claw biasing mechanism biases the locking member 130 toward the hinge mechanism part side. Specifically, the latching claw urging mechanism is configured by attaching the latching member 130 to the lid main body 121 via a spring member such as a coil spring or a resin spring.

(3) Lower exterior member The lower exterior member 150 is a substantially truncated conical member, and mainly includes a main body portion 151 and a hinge connecting portion 141 as shown in FIG. 9. And this lower exterior member 150 is arrange | positioned so that the upper part of the cylindrical wall part 111 of the plug main body 110 may be enclosed, as FIG. 2 and FIG. 9 shows. In such a case, the standing wall portion 115 of the plug body 110 is positioned substantially above the upper surface of the lower exterior member 150 in a side view.

  As shown in FIGS. 5 and 9, the main body 151 is mainly formed of a side wall 151a and a rear ceiling wall 151b. The side wall 151a has a truncated cone shape. As shown in FIGS. 5 and 7, the rear ceiling wall 151b covers the rear part of the side wall 151a.

  As shown in FIGS. 7 and 9, the hinge connecting portion 141 extends upward from the rear top wall portion 151b. And this hinge connection part 141 comprises the hinge mechanism part 140 with the connection piece 142 of the cover body 120 so that it may mention later. The hinge connecting portion 141 is formed with a through hole through which a hinge pin (not shown) is inserted.

(4) Hinge mechanism part The hinge mechanism part 140 is mainly comprised from the hinge connection part 141, a pair of connection piece 142, and a hinge pin (not shown) as FIG.5, FIG.7 and FIG.8 shows. . The hinge mechanism part 140 is configured such that the through hole of the connecting piece 142 and the through hole of the hinge connecting part 141 communicate with each other so that one continuous through hole is formed. It is formed by inserting a hinge pin through the through-hole in a state of being sandwiched between.

<How to use the plug>
First, a desired beverage in the container 200 is poured.

  Next, the male screw part 112 of the plug body 100 is screwed into the female screw part 211 of the container 200 to attach the plug body 100 to the container 200 to complete the beverage container 300 (see FIGS. 10 and 11). At this time, the packing 119 comes into contact with the protrusion 212 at the lower end of the opening 210 of the container 200 to keep the container 200 and the stopper 100 watertight. Here, the container 200 may be a normal container or a vacuum double container. Examples of the material of the container 200 include alloys such as stainless steel and resins.

  And the user of this drink container 300 holds the container 200 so that the opposite side of the hinge mechanism part 140 of the stopper 100, ie, the front side, may become this side. Subsequently, the user, for example, holds the exposed portion 121a of the lid body 121 with the belly of the thumb of the non-dominant hand, inserts the index finger of the dominant hand into the operation recess 132, and makes contact with the side wall portion 132a. Pull the index finger toward you against the urging force of the force mechanism. Then, the locking member 130 moves from the back side to the near side in the plug body 100 (see FIG. 4), and as a result, the locking claw 133 is pulled out from the locking claw receiving portion 115b, and the lid body 120 with respect to the plug main body 110. Is released. Subsequently, the user lifts the lid 120 upward and falls backward. Then, the user puts a mouth on the central portion 115a of the standing wall and drinks the beverage while tilting the beverage container 300 upward. At this time, the locking member 130 is returned to the original position by the locking claw urging mechanism (see FIG. 6).

  When the lid 120 is closed, the user rotates the lid 120 forward and pushes the lid 120 into the plug body 110 as it is. Then, the latching claw 133 slides forward while coming into contact with the upper part of the latching claw receiving portion 115b, and finally the locking claw 133 is inserted into the latching claw receiving portion 115b. As a result, the lid 120 is locked to the plug body 110.

<Features of the plug according to the embodiment of the present invention>
(1)
When the stopper 100 according to the embodiment of the present invention is attached to the container 200 to form the beverage container 300, the user of the beverage container 300 normally has the container so that the opposite side of the hinge mechanism portion 140 is in front. 200 is held and the locking member 130 is operated. That is, the user slides the locking member 130 from the back side to the near side. As far as the inventor of the present application knows, no plug 100 having such a locking mechanism has been proposed to date. Therefore, according to the present invention, it is possible to meet the demands of those who wait for the plug 100 as described above.

(2)
In the plug body 100 according to the embodiment of the present invention, when the lid body 120 is locked to the plug body 110, the locking member 130 moves obliquely downward in a side view. For this reason, the user can lock the lid 120 with respect to the plug body 110 simply by pressing the lid cover 122.

(3)
In the plug body 100 according to the embodiment of the present invention, when the lid body 120 is locked to the plug body 110, the top surface and the outer peripheral surface of the main body portion 131 of the locking member 130, and the exposed portion 121 a of the lid body 121. The top surface and the outer peripheral surface of the lid cover 122 have no steps and form a smooth flat surface and a curved surface. On the other hand, when the locking of the lid 120 with respect to the plug body 110 is released, the top surface and the outer peripheral surface of the main body 131 are higher than the exposed portion 121a of the lid main body 121 and the top and outer peripheral surfaces of the lid cover 122. As a result, there is a difference in level between the top surface and outer peripheral surface of the main body 131 and the exposed surface 121a of the lid main body 121 and the top and outer peripheral surfaces of the cover cover 122. As far as the inventor of the present application knows, no stopper 100 having a locking mechanism that causes such a shape change has been proposed to date. Therefore, according to the present invention, it is possible to meet the demands of those who want to wait for such a plug 100.

(4)
In the plug body 100 according to the embodiment of the present invention, the top wall portion of the lid main body 121 covers the standing wall portion 115 with almost no gap in a side view, and the side wall portion of the lid body 121 has almost no gap with a plan view.

Therefore, the beverage from the through hole 113 toward the semicircular portion of the standing wall 115 is rectified by the locking claw receiving portion 115b toward the standing wall central portion 115a. Therefore, for example, even when the user rushes to drink after exercise, the beverage is unlikely to leak from the user's mouth.

(6)
In the plug body 100 according to the embodiment of the present invention, the operation portion is formed as a concave portion and is disposed at a substantially central portion of the plug body 100 in plan view. For this reason, in this stopper 100, even when the user carries the beverage container 300 in a bag and carries it, it is difficult for an external force to be applied to the operation portion (operation recess 132) in the bag. Therefore, the plug 100 is not easily opened in the bag when being carried by the bag.

(7)
In plug 100 according to the embodiment of the present invention, lid cover 122 covers the side surface of hinge mechanism 140. For this reason, in this plug 100, the hinge pin is not visible to the user, and the hinge pin does not fall off. Therefore, the plug 100 has a good appearance and is robust.
