Description

  The present invention relates to an inner plug that is attached to a container port of a liquid container and used for dispensing or drinking liquid, and more particularly, relates to an inner plug for a liquid container having a large liquid passage for direct drinking. Is.

  In general, the inner cap of a liquid container, commonly called a water bottle, is 1) a straight type for drinking by directly opening the inner cap, 2) a type for opening the liquid flow path by pushing the button and opening the liquid flow path, and 3) a button. There is a type in which the upper part of the inner plug is opened widely and water is poured while picking. These water bottles are different in the structure of the inner plug, and as a result, there is a difference in use as in the above-mentioned type. In the case of 2) and 3), you must develop a special plug for each of the cups attached to the liquid container, and if you purchase any one of 1) to 4), how to drink Means automatically. Also, when you want to have a hot drink, you cannot use the direct drink type 1) or the straw type 4). To be limited.

  In addition, there is a beverage flow path in the liquid container's inner stopper, and the conventional structure tends to become dirty and unsanitary, so it is necessary to perform proper cleaning. There is a problem that cleaning is difficult because the diameter of the spout is small. For this reason, there is a type in which this type of inner plug can be disassembled and disassembled every time it is cleaned. However, it is a burden to repeat disassembling and assembling each time cleaning is performed, and it is natural that dirt is accumulated in the flow path and the valve body if care is not taken. In addition, there is a part where the fingertip and the instrument cannot reach even if the structure is disassembled and cleaned, and such a part can hardly be cleaned. In the case of the types 2) and 3), it is difficult to check the open / close state sensuously or visually from the form of the operation buttons, which causes forgetting to close or liquid leakage.

  The inner plug which is the subject of the present invention is attached to the container mouth of a liquid container and can be used in a direct drinking type or a dispensing type. That is, it can be applied as a straight type in which a mouth is directly put on the inner plug and drinks, or as a type in which a valve is opened through a certain operation and a liquid flow path is opened to inject water. The liquid container can be applied to both a so-called thermos-type container that can be kept warm and cold, and a liquid container that does not have a warm and cool function. The liquid flow path has a flow cross-sectional area several times larger than that of the straw, and the upper opening of the stopper body is a curved surface that is thin and smoothly shaped to be suitable for drinking with a direct mouth. By comprising, it becomes easy to use when using as a straight type mentioned above or as a type poured out. As the form of the smoothly shaped curved surface, it is desired that the curved surface is formed, for example, about the edge of a drinking container such as a mug.

  An inner stopper for a liquid container according to the present invention includes a stopper main body and an opening / closing valve member provided on the stopper main body so as to be vertically movable. The stopper main body has a liquid flow path penetrating the inside vertically, the lower end of the liquid flow path is a lower opening communicating with the liquid container, and the upper end of the liquid flow path is an upper opening serving both as a drinking mouth and a spout.

The on-off valve member may be provided so that a part thereof is exposed in the liquid channel, or may be provided so as not to be exposed in the liquid channel. The on-off valve member is provided in the stopper main body so as to be movable up and down, and moves upward to approach the lower opening of the stopper main body from below to close the liquid flow path, and moves downward to leave the lower opening to move the liquid flow path. open. A valve body is provided at the lower part of the open / close valve member, and an open / close valve member for moving the valve body up and down by an upper operation lever is provided. Since the valve body can be detachably attached to the lower end of the on-off valve member by screwing or the like (the invention according to claim 2), it can be removed and thoroughly cleaned.

  An elastic body that urges the valve body in a direction to close the lower opening of the plug body is disposed on the plug body outside the liquid flow path. A metal coil spring or the like is used for this type of elastic body. However, since the elastic body does not touch the liquid by placing the elastic body on the plug body outside the liquid flow path, it is rusted or unsanitary. There is no fear of becoming.

  The on-off valve member is urged by an elastic body in a direction to close the lower opening of the plug body by the valve body, and is operated by an operation lever in a direction to push down the valve body against the above urging and open the lower opening. (Invention of claim 3). The operation of closing the lower opening of the valve body is automatically performed under the action of the elastic body, and the operation lever keeps the lower opening opened by the valve body against the elasticity of the elastic body, or the operation lever It is provided to keep the valve body in the closed position by the action of the urging force.

  An operation lever is attached to the upper part of the stopper body by a support shaft, and the opening / closing valve member engaged with the operation lever is moved up and down by raising and lowering the operation end located on the outer periphery of the stopper body. This is one desirable form (the invention according to claim 4). By taking the form in which the operation end part moves up and down, for example, the state of the operation lever can be easily grasped from the appearance as compared with the case where the protruding height of the button is changed.

  The subject of the present invention is an inner stopper, which is used by being attached to a liquid container, but what kind of attachment structure is applicable is free. That is, any structure may be used for mounting on the container opening of the liquid container, and any known structure can be applied. Examples of known structures include, for example, a plug-in type internal plug, a screw-in type internal plug, a bayonet fitting type internal plug, and the like, and the present invention can be applied to all of these internal plugs.

  Since the present invention is configured and operates as described above, even if it is a straight type (direct drinking type) for drinking by directly opening the inside plug, the valve is opened through a certain operation and the liquid flow path is opened. It can also be applied as a type (pouring type) in which water is opened and poured, and an inner stopper for a liquid container that enables two types of usage with one inner stopper can be provided. Further, according to the present invention, the inner diameter of the liquid flow path is not small enough to arrange a straw, but has a diameter that can be poured at a flow rate suitable for direct drinking, and the valve body can be attached to and detached from the opening / closing valve member Therefore, it is possible to provide a sanitary stopper for a liquid container that is easy to clean and hygienic. In addition, according to the present invention, since the operation end of the operation lever moves up and down on the outer peripheral side of the stopper body, it is easy to check the open / close state sensuously or visually, and it is difficult to forget to close the valve. An internal spigot can be provided.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows an example of an inner stopper 11 for a liquid container according to the present invention attached to a container opening of a liquid container. Reference numeral 10 denotes a container opening of a liquid container, and the container opening 10 has a substantially cylindrical shape. The plug body 12 having the outer shape is fitted. The plug body 12 has a liquid flow path 13 that penetrates the inside of the plug body vertically, and a lower opening 14 that opens at the lower end of the liquid flow path is formed as a circular opening that is concentric with the cylinder of the plug main body 12 and has a small diameter. . On the other hand, the upper opening 15 serving as a drinking mouth and a spout opening directly at the upper end of the liquid flow path 13 is formed in a half-circular opening, but the stopper body 12 has a large diameter at the upper part. It is assumed that the cross-sectional area of the lower opening 14 is substantially the same as the opening area, and the liquid flow path 13 has a minimum diameter corresponding to several straws.

  The inner plug 11 according to the present invention can be applied as a straight type with a mouth open and drink, or as a type in which the liquid flow path 13 is opened and water is poured by opening the valve. The upper opening 15 is thin so as to be suitable for drinking with a mouth directly, and is formed of a curved surface slightly extending outward. As a result, the upper surface of the inner plug 11 has a slope that becomes a protruding end at the top end of the upper opening 15 and decreases toward the operation lever 24 described later. In addition, as a curved surface required for the drinking mouth of the upper opening 15, it has the smoothness of the edge of drinkers, such as a cup, for example.

  A vertical sliding groove 16 is formed on the side surface of the stopper body 12 located inward of the liquid flow path 13, and an opening / closing valve member 17 disposed therein is provided so as to be movable by sliding in the vertical direction. . The on-off valve member 17 approaches the lower opening 14 from the lower side by moving upward and closes the liquid flow path 13, and moves away from the lower opening 14 to open the liquid flow path 13 by moving downward. At the bottom. The illustrated valve body 18 has a screw 19 at the center, and is detachably attached to the female screw 20 at the lower end of the on-off valve member 17 by screw coupling (see FIGS. 5 and 6). In order to completely close the lower opening 14, a packing 21 that contacts the valve body 18 is attached around the lower opening of the plug body 12. Reference numeral 22 denotes a contact surface, which is a portion with which the peripheral portion 23 of the valve body 18 comes into contact.

  In order to move the valve body 18 up and down, an operating lever 24 is provided on the stopper body 12 positioned above the opening / closing valve member 17 so as to be swingable by a support shaft 25. An elastic body 27 that biases the valve body 18 in a direction to close the lower opening 14 of the plug body 12 is disposed in the void 26 outside the road. The elastic body 27 is in contact with a spring receiver 28 provided on the side integrally with the opening / closing valve member 17 at the upper end, and is in contact with the bottom of the cavity at the lower end. Reference numeral 29 denotes a bottom ventilation hole.

  The operation lever 24 has an engaging portion 30 at an inner end, and an engaging counterpart portion 31 that engages with the engaging portion 30 in order to move the valve body 18 up and down at the upper portion of the on-off valve member 17. In addition, a finger hook portion is provided at the outer end portion as the operation end portion 32 that can be operated with the fingertip. The operation lever 24 is in lever engagement with the mating counterpart 31 as will be described later so as to move the open / close valve member 17 up and down by raising and lowering the operation end 32 located on the outer periphery of the stopper body 12. 3 and 4, reference numeral 33 denotes a stopper upper opening, and the above-described operation lever 24 and the like are incorporated therein. Reference numeral 34 denotes a meat removal portion.

  The engaging portion 30 and the engaging counterpart 31 have a surface and a curved surface shown in detail in FIG. First, the engagement portion 30 is provided with a curved surface 35 at the innermost lower portion, and engages with an inner counterpart curved surface 36 of the engagement counterpart portion 31 in a closed state (see FIG. 1). Further, a curved surface 37 is provided at the outermost lower portion of the engaging portion 30, and engages with an outer mating curved surface 38 of the engaging mating portion 31 during the lever operation. Further, the engaging portion 30 is provided with an inner surface 39 adjacent to the outer corner of the inner lower curved surface 35, which is engaged with the mating wall surface 40 at the end of the lever operation and becomes a stopper. The engaging portion 30 is provided with an outer surface 41 adjacent to the inner corner of the outer lower curved surface 37, which is engaged with the mating surface 42 at the end of the lever operation.

  In such a configuration, when the operation end portion 32 of the operation lever 24 is lowered as shown in FIG. 1 or FIG. 8, the curved surface 35 of the engagement portion 30 engages with the counterpart curved surface 36 of the engagement counterpart portion 31. In this state, the on-off valve member 17 is raised most by receiving the elastic force of the elastic body 27, and the valve body 18 closes the lower opening 14. Here, when the operation end portion 32 is pulled upward as shown by the arrow in FIG. 8 and the operation lever 24 is rotated in the clockwise direction in FIG. 8, the curved surface 35 of the engaging portion 30 is detached from the mating curved surface 36 by lever action. While the outer lower curved surface 37 is engaged with the mating curved surface 38 (see FIG. 9), the on-off valve member 17 is pushed down against the biasing force of the elastic body 27, and the inner surface 39 is engaged with the mating wall surface 40, The direction surface 41 engages with the mating surface 42 and stops, so that the valve element 18 is completely opened. Since the operation end 32 protrudes upward in the valve open state (see FIG. 10), for example, the state of the operation lever 24 can be easily grasped from the appearance as compared with the case in which the protrusion height of the button is changed. As already mentioned.

  In the valve open state shown in FIG. 10, since the mating surface 42 is positioned substantially in the vertical line of the support shaft 25, the force acting from the elastic body 27 or the like is received at the support shaft 25, The state (valve open state) is maintained. Accordingly, by tilting the liquid container, the user can cause the liquid inside to flow out from the upper opening 15 through the liquid flow path 13, so that the user can make a mouth on the upper opening 15 or the upper opening. It can be drunk from 15 and drunk.

  After quoting, when the operation end 32 is pushed down by the fingertip and the operation lever 24 is rotated counterclockwise in FIG. 9, the engaging portion 30 pushes down the mating surface 42 at the outer surface 41 by the lever action and the same. Rotation continues in the direction, and after that, it moves together with the opening / closing valve member 17 that moves upward by the urging force of the elastic body 27, and the curved surface 35 of the engagement portion 30 engages with the counterpart curved surface 36 of the engagement counterpart portion 31. Stop in state. In this state, the peripheral portion 23 of the valve body 18 is brought into pressure contact with the contact surface 22 of the packing 21 by the urging force of the elastic body 27 to be in a liquid-tight valve closed state.

  Thus, in the liquid container inner plug 11 according to the present invention, the operation lever 24 is attached to the upper part of the plug body by the support shaft 25, and the operation end 32 positioned on the outer periphery of the plug body 12 is raised and lowered. Thus, the opening / closing valve member 17 that is lever-engaged with the operation lever 24 can be moved up and down, so that the opening / closing operation of the valve body 18 is extremely easy. In addition, since the operation end 32 is configured to move up and down, it is easy to grasp the state of the operation lever 24 from the appearance, and it is easy to prevent misunderstanding.
