Description

  The present invention relates to a portable beverage container provided with a stopper and a cup attached to a spout of a container body.

  The portable beverage container is mounted in such a manner that a stopper is mounted on the spout of the container body, and a cup for drinking is crowned so as to cover the upper surface of the stopper. Moreover, as a plug body of a portable beverage container provided with a cup, members having various structures have been proposed in the past. However, in order to ensure the plug function, the plug body is moved downward by the urging force of the ridge. One incorporating an on-off valve mechanism for closing the opening is known. The basic structure is that an opening is provided below the plug, an outflow passage is formed in the plug to communicate the lower opening and the outlet on the upper surface of the plug, and a valve element that opens and closes the lower opening is provided. And an opening / closing valve mechanism having a spring that biases the valve body in a direction to close the lower opening, and an operation mechanism for operating the valve body are incorporated in the plug body.

  Many configurations adopted as a general structure of the on-off valve mechanism section and the operation mechanism section described above are that the valve mechanism section is attached to the valve body that opens and closes the opening below the plug body from the lower side and the valve closing direction. An urging member for urging, and a valve rod coupled to the valve body, and an operation mechanism portion for opening and closing the valve body includes an operation body having a cam surface protruding downward in a predetermined operation, the cam surface Thus, the valve opening is formed by lowering and moving the top of the valve stem (FIG. 1 of Patent Document 1 and FIG. 2 of Patent Document 2).

  Moreover, the structure (direct drinking type) of drinking directly from the outlet of the said stopper, without providing a cup is also known. For example, FIG. 2 of Patent Document 1 shows a stopper body that is provided with a thin cylindrical outlet, and that has a lip attached directly to the outlet when the valve is opened. Shows a plug body for drinking with the lips directly attached to the outlet opening on the top surface of the plug body.

  Of course, a direct drinking type beverage container not provided with the stopper structure is also widely known. The top of the plug is formed in a bowl shape so that it can be drunk directly, and an outlet is provided on the bottom, or a narrow cylindrical outlet is provided, and a hinge is connected to the opposite side of the outlet to rotate it. There are also known ones that are provided with a closing body that opens and closes the outlet by operation (Japanese Patent Laid-Open Nos. 2002-102078 and 2008-23202).

JP 2002-58606 A. Japanese Patent Application Laid-Open No. 2004-175402. JP-A-9-299253.

  A beverage container equipped with a stopper body that is equipped with the opening / closing valve mechanism is equipped with a cup, so that it is poured into a cup for drinking in a cup, but at the same time other than drinking a cup (indirect drinking) You may want to drink directly. As a countermeasure, as shown in FIG. 11 of Patent Document 1, an indirect drinking plug body and a direct drinking plug body are provided so as to be replaced with one beverage container. In addition, in a commercial product, a beverage container provided with a cup and a stopper equipped with an opening / closing valve mechanism is attached as an accessory with a direct drinking stopper that turns and opens and closes as a replacement, and means to respond by changing the stopper Has been done.

  However, the provision of two indirect drinking plugs and two direct drinking plugs naturally increases the product cost, and it is necessary to replace the plugs during use, which is cumbersome.

  Further, Patent Document 3 shows a configuration in which a lip is directly attached to the upper opening portion of the outflow passage in a plug body having an on-off valve mechanism, but the liquid level is not visible at all. For drinking, it is very difficult to drink when the container drink is hot.

  In addition, the swivel turning opening and closing plug body often used as a direct drinking plug body has a problem that it becomes difficult to drink the closing body that opens and closes close to the face because the container is tilted when drinking directly. is there. Moreover, this structure is urged | biased by the direction which the obstruction body opens an outflow port so that opening operation | movement of an obstruction body may be performed rapidly. For this reason, in order to maintain the closing of the outlet, a locking structure for the closing body is necessary. If the operability of the locking structure is pursued, it is easy to come off, and if it is made robust, there is a problem in operability. However, when the internal pressure of the container increases, such as when the beverage is hot, the internal pressure acts in the opening operation direction of the closed body, and therefore has a fundamental problem regarding the maintenance of the closed body.

  Therefore, the present invention proposes a portable beverage container that can handle both indirect drinking and direct drinking with a single stopper.

  A portable beverage container according to the present invention includes a bottomed cylindrical container main body, a plug mounted on the upper spout of the container main body, and a cup mounted on the crown so as to cover the upper surface of the plug body. A portable beverage container, wherein the plug body is provided with an opening portion below the plug body, an outlet port communicating with the opening portion is provided above the plug body, and the valve body portion that opens and closes the opening portion from below. And an urging member for urging in the valve closing direction, an on-off valve mechanism portion having a valve rod portion protruding above the valve body portion, and an operation mechanism portion for opening and closing the on-off valve mechanism portion, An outlet is provided in the vicinity of the edge of the top surface of the plug body, a peripheral wall having a predetermined height is formed surrounding the outer edge side of the outlet, and the operating mechanism is slidably mounted on the top surface of the plug body, and the slide Back of the movement that opens and closes the outlet by moving and moves the valve stem up and down by sliding And it is characterized in that comprising constituted by sliding operating body provided with a.

  Thus, the beverage container is provided with a stopper in a sealed state at the upper spout of a container main body that contains a beverage, and further provided with a cup to be used for carrying a beverage. Thus, the outlet is closed, and the lower opening is closed by the valve body, so that it can be carried without causing liquid leakage. When drinking, remove the cup to expose the top surface of the plug body, operate the slide operation body to open the outlet, and simultaneously push down the valve stem to open the lower opening that was blocked by the valve body . When the container body is tilted in the above state, the internal beverage flows from the lower opening to the outside through the outflow path, and can be drunk directly with a lip attached to the peripheral wall or poured into a cup indirectly. To drink.

  In particular, when drinking directly, a beverage that has a peripheral wall with a sufficient height and that has flowed out of the outlet by inclining the container body is placed in the outlet part (an indentation at the time of inclination formed by the upper surface of the stopper and the peripheral wall). Since it can be drunk and drunk while visually recognizing the liquid level, for example, even a hot beverage can be drunk safely without being burned. Furthermore, when pouring into the cup, it can be performed while visually confirming that the beverage flows out to the peripheral wall, so that adjustment of the outflow amount (inclination angle adjustment of the beverage container) can be easily performed.

  According to the present invention (Claim 2), in the portable beverage container, in particular, the upper surface of the plug body is formed as an inclined surface with a lower outlet side, and the peripheral wall surrounds only the lower portion of the upper surface of the plug body. It is provided.

  Therefore, as described above, when the container is tilted at the time of drinking, the beverage remains in the low place even if the peripheral wall is low, and the beverage can be drunk in a state where the liquid level is visually recognized. It returns to the container from the outlet.

  In the portable beverage container according to the present invention (Claim 3), in the above plug body, the slide operation body further opens and closes the outlet provided in the low position at the tip portion, and the outlet upper surface position is set. Is provided so as to be slidable along the inclined surface in the height direction opposite to the outflow port, and so that the tail end of the slide moving body protrudes from the cup mounting position in the open state of the outflow port. It is.

  Therefore, when the outflow port is open, the tail end of the slide operation body protrudes outward from the cup mounting position, so that it is impossible to mount the cup on the crown in the open state of the outflow port and the valve body. It will inform the state.

  The present invention employs a valve mechanism having a valve body that is biased in the closing direction in the above-described configuration, performs a reliable plug function when carried except when drinking, and prevents liquid leakage and the like. It has a peripheral wall of a predetermined height that surrounds the outer edge of the outflow port, and it is not without any other member (for example, a member such as a turning-rotating obstruction member) that obstructs drinking. Therefore, direct drinking from a container can be easily performed, and indirect drinking by pouring into an attached cup is also possible, and indirect drinking with a single stopper without equipped with multiple stoppers In addition, it was easy to drink directly.

The whole perspective view of the stopper of the embodiment of the present invention. FIG. Explanatory drawing at the time of a drinking state (sectional drawing). The exploded perspective view. FIG. Sectional drawing of the principal part of the embodiment.

  Next, an embodiment of the present invention will be described.

Further, a connecting tube portion 124 having a connecting screw groove 123 formed on the inner peripheral surface is erected in the center of the bottom portion, and a part of the bottom portion on the outer peripheral side of the connecting tube portion 124 is opened to form a lower opening 125. On the outer periphery of the lower end of the part 121, a packing 126 is used to closely contact the inner surface of the upper spout 21 by screwing the outer peripheral part 11 of the plug body and to close the lower opening 122 by contacting a valve body part 131 described later. Is provided.

  The on-off valve mechanism unit 13 includes a valve body part 131, a valve rod part 132, and an urging member 133. The valve body part 131 is located below the lower opening part 125 and opens and closes the lower opening part 125. It is what you make. The valve stem portion 132 has a length that connects the lower end to the valve body portion 131 and projects through the bottom surface of the bottomed tubular portion 131 and protrudes upward from a stopper upper surface 144 described later.

  The urging member 133 is interposed between the bottom portion of the bottomed tubular portion 131 and the umbrella receiving portion 134 provided in the upper portion of the valve stem portion 132. The urging member 133 is pulled upward to lower the lower opening 125. It is energized in the direction of closing.

  The plug body upper surface portion 14 includes a fitting mounting portion 141, a flange 142, a plug body upper surface 143, and a peripheral wall 144. The fitting mounting portion 141 is connected to the stepped portion 122 of the lower plug body 1a. A fitting is achieved, and sealing is realized when the upper and lower plug bodies 1a and 1b are connected by interposing an O-ring 145 between the inner peripheral surface of the stepped portion 122 and the outer peripheral surface of the fitting mounting portion 141. Like to do.

  The flange 142 is provided around the upper outer periphery of the fitting mounting portion 141, and is disposed on the upper end surface of the stopper outer peripheral portion 11 in a mounting manner.

  The plug upper surface 143 is provided on the inside of the fitting mounting portion 141 so as to have a lid shape. The plug body upper surface 143 is formed on an inclined surface that is lowered on one side, and an outlet 146 that passes through the front and back is provided at the lowest point near the edge side. It is a thing.

  The peripheral wall 144 surrounds the edge of about half of the outer periphery around the position where the outflow port 146 is provided, and the portion corresponding to the outflow port 146 is made high enough to attach the lips and is opposite It is formed so as to be gradually lowered toward the side.

  The mounting cylinder portion 15 has an inner diameter capable of housing the valve rod portion 132, the urging member 133, and the umbrella receiving portion 134, and is open at the center of the stopper upper surface 144 and protrudes downward from the stopper upper surface 144. Thus, a connecting screw 151 corresponding to the connecting screw groove 123 is provided on the outer periphery of the lower end.

  The operation mechanism portion 16 is formed by a slide operation body, and is attached to the stopper upper surface 143 so as to be movable from a low place to a high place along an inclined surface, and a tip portion opens and closes the outlet 146. If the operation plug 161 is provided on the front surface and the plug body 1b is integrated with the lower plug body 1a on the back surface, the valve stem portion is moved in the opening direction. A slope surface (operating back surface) 162 that lowers the upper end of 132 by lowering the pressure, and a lower pressure holding surface (operating back surface) 163 that maintains a downward movement position with a slope opposite to the slope surface 162 with respect to the lid upper surface 143. Is formed.

  Further, the slide operation body (operation mechanism unit) 16 has the outlet 146 opened, and the tail end of the slide operation body 16 projects to the position of the cup lid 4 when the cup lid 4 is attached to the container body 1. In the protruding state (opening state of the outlet 146), the cup lid 4 cannot be mounted.

  The upper plug body 1b is integrally formed by screwing the connecting thread 151 of the mounting cylinder portion 15 into the connecting screw groove 123 on the inner peripheral surface of the connecting cylinder portion 124 of the lower plug body 1a to store the beverage. The plug body insertion part 12 is inserted into the upper spout 21 of No. 2, the outer peripheral part 11 of the plug body is screwed and attached to the shoulder member 3, and the cup lid 4 is further attached to carry the beverage.

  During carrying (when not drinking), the plug 126 is sealed between the plug insertion portion 12 and the upper spout 21 when the plug 1 is mounted, and the plug 1 itself is biased by the biasing member 133. The lower opening 125 is sealed by the valve body 131 thus made, and the state where no liquid leakage occurs is maintained.

  When drinking, the cup lid 4 is removed, and the slide operation body (operation mechanism part) 16 is moved and operated in the outer peripheral direction (on the side opposite to the peripheral wall forming portion). As the slide operating body 16 moves, the top of the valve stem 132 is pushed by the slope surface 162 and moves downward, and when the top of the valve stem 132 reaches the lower pressure holding surface 163, the valve body 131 moves downward. In addition, the position is maintained, and the outlet 146 is also opened at the same time.

  Therefore, when the beverage container is inclined toward the outlet 145, the beverage in the container flows out of the container through the lower opening 125, the inner side of the bottomed cylindrical portion 121 (outflow passage a), and the outlet 146. become.

  Since the beverage flowing out of the container flows out along the inner surface of the peripheral wall 144, it may be poured into the cup lid 4 for drinking (indirect drinking), or directly with lips attached to the peripheral wall 144. (Direct drinking) may be used.

  When the container position is returned to the original position, the beverage remaining in the lower portion of the peripheral wall 144 and the stopper upper surface 143 naturally flows into the container body 1 from the outlet 146, and when the slide operation body 16 is returned, the beverage is closed (portable). Time state).
