Description

  The present invention is an invention relating to a spout structure that is mainly a liquid container such as a portable fountain bottle or a water bottle, and that allows a beverage to flow out smoothly from its drinking spout or spout.

In liquid containers such as portable fountain bottles and water bottles, the opening of the container body itself that contains the beverage is used as a spout, and the content liquid is poured out from this, as disclosed in Patent Document 1 In some cases, a stopper that closes the opening of the container body is provided, and the content liquid is poured out or drunk from a spout formed in the stopper. The liquid container disclosed in Patent Document 1 can be drunk either by drinking directly from a spout or by pouring into a cup or the like. In addition, a liquid container is also known in which a stopper is provided with a straw-like spout.
JP 2003-155050 A

  In a liquid container that uses a large opening as a spout in a conventional liquid container, the content liquid is poured out relatively smoothly, but if the spout is small, air corresponding to the volume of liquid to be discharged is contained in the container. Since it is difficult to flow in, the way in which the content liquid is discharged becomes irregular as in the state of breathing, and it is difficult to smoothly dispense the liquid. For this reason, it becomes difficult to use in either case of drinking directly or pouring into a cup.

  In order to eliminate this drawback, in conventional liquid containers such as portable fountain bottles, vents are provided in the stopper and the container body itself in addition to the spout, so that air is supplied into the vessel when drinking or injecting liquid. I am doing so. However, if this is the case, it is necessary to completely seal both the spout and the air hole when carrying with the cap closed, and it is difficult to completely seal both. The drawbacks such as high possibility of leakage could not be avoided.

  In order to eliminate the above drawbacks, conventionally, an inlet is provided in the stopper or the container body itself. If a stopper is provided with an inlet other than the outlet, the liquid may leak from the inlet, so when sealing the outlet, both the outlet and inlet are completely sealed. However, there is a drawback that the structure is complicated and the possibility of liquid leakage from the intake port due to poor sealing is high.

  In view of the drawbacks of the prior art described above, it is an object of the present invention to realize a spout structure that can smoothly perform liquid pouring or drinking without providing an air inlet separately from the spout. Another object of the present invention is to realize a liquid container spout structure that is capable of performing smooth liquid pouring or sucking and that is easy to handle for cleaning and other purposes.

  In order to achieve the above object, the present invention has a structure in which a stopper set 2 constituted by a separable stopper cover 3 and a stopper 4 is detachably attached to the upper end portion of the container body 1. And the inside of the extraction pipe | tube 5 is divided and the ventilation pipe | tube 6 is arrange | positioned in the inside of the extraction pipe | tube 5 which is formed in the stopper 4 and protrudes out of the vessel at the upper position of the inclination inclined for the extraction. The vent pipe 6 formed inside the pouring pipe 5 has an opening end inward of the opening end of the pouring pipe 5 and a position that does not hinder the opening and closing of the cap, and the tip communicates with the inside of the vessel. It is preferable to arrange so as to.

  According to the spout structure of the liquid container of the present invention as set forth in claim 1, it is either the case where the content liquid is drunk directly from the spout 5 a which is the open end of the spout pipe 5 or the case where it is poured into a cup or the like. However, since air flows into the container through the vent pipe 6 formed inside the extraction pipe 5, the content liquid can be smoothly discharged. That is, in the present invention, the vent pipe 6 is formed inside the pouring pipe 5, but when the container body 1 is tilted for pouring, the content liquid passes below the pouring pipe 5. At the same time, air flows into the interior through the upper side of the extraction pipe 5. At this time, the flow of the content liquid and the flow of air are separated by the presence of the vent pipe 5, and a smooth outflow of the content liquid can be realized. Further, in the case of carrying or the like, if the spout 5a is sealed, the vent pipe is also sealed at the same time, and the sealing mechanism can be simplified.

  Further, according to the present invention, a stopper set 2 comprising a separable stopper cover 3 and a stopper 4 is detachably attached to the upper end portion of the container body 1, and a pour tube formed on the stopper 4 and protruding outside the container. Since the vent pipe 6 is disposed inside the pipe 5, only the plug 4 can be separated and the entire vent pipe 6 can be easily cleaned. If the vent pipe 6 is formed in the container body 1 itself, the inner end of the vent pipe 6 cannot be washed.

  According to the second aspect of the present invention, when the cap 7 is attached to the spout 5a that is the open end of the spout 5, the vent pipe 6 does not get in the way. Further, even when drinking directly, the presence of the vent pipe 6 does not get in the way, and in any case, the vent pipe 6 is present, but the same as in the case of the single dispensing pipe 5 Can be handled without any problem.

Hereinafter, an embodiment of a spout structure in a liquid container according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a longitudinal sectional view of only the upper part of a liquid container showing an embodiment of the present invention, and FIG. 2 is a perspective view of the entire liquid container.

  The liquid container of the illustrated embodiment is mainly intended to be used when carrying a sport or the like and drinking a relatively large amount of water alone. The container body 1 has a shoulder member 9 fixed to the upper portion of the vacuum double bottle 8 and a bottom body 10 fixed to the lower end portion thereof, and a portal-shaped handle 11 that can move up and down is mounted on both the left and right sides of the shoulder member 9. ing. A plug cover 3 is detachably attached to the shoulder member 9 by a screwing operation, and a cap 7 provided on the upper surface of the plug cover 3 with a rear end as a fulcrum and biased in the opening direction by a spring 12 is opened. Drink directly from the spout 5a of the exposed pipe 5.

  An opening / closing button 13 for opening and closing the cap 7 is disposed at the front end of the stopper cover 3. The open / close button 13 is attached to a button accommodating portion formed in the front portion of the stopper cover 3. The lid opening / closing button 13 is urged forward by a spring 14 and maintains a closed state by engaging a hooking claw 16 formed at the tip of the cap 7 with a receiving claw 15 formed at the upper end portion. By pressing 13, the engagement of the receiving claw 15 and the hanging claw 16 is released, and the cap 7 is opened instantly by the elasticity of the spring 14.

  The plug set 8 includes a substantially cap-shaped plug cover 3 that can be screwed to the shoulder member 9 and a plug 4 that is separable from the plug cover 3, and the two are combined and handled as the plug set 2. That is, the substantially cap-shaped stopper cover 3 that is screwed onto the shoulder member 9 of the container body 1 is formed with a pouring tube support tube 17 on the top wall portion, and a cap 7 is provided so as to cover the upper portion of the top portion. . On the other hand, the stopper 4 has a substantially cap-like shape, and an opening of the vacuum double bottle 8 is attached to the outer peripheral portion of the lower end, specifically, a packing 18 that is in close contact with the throttle portion 8a and is poured upward. A tube 5 is formed. The extraction pipe 5 is configured to be able to move freely in the axial direction through the extraction pipe support cylinder 17 of the plug cover 3 and to maintain a watertight state by attaching a packing 19. ing.

  A packing support bar 20 projects downward from the cap 7, and the spout 5 a at the tip of the discharge pipe 5 is sealed by the packing 21 attached to the packing support bar 20. The packing 21 is substantially cap-shaped, and is attached to the packing support rod 20 from below, and an outer collar 22 is formed at the upper end. Therefore, the spout 5a which is the upper end of the pouring pipe 5 pushes up the lower surface of the outer casing 22 of the packing 21, and the sealed state is maintained by the bending elasticity of the outer casing 22 of the packing. That is, the entire packing 21 enters the inside of the pouring pipe 5, and the spout 5 a is brought into contact with the lower surface of the outer casing 22 formed at the upper end of the packing 21.

  As shown in FIG. 5, the extraction pipe 5 formed in the stopper 4 has a cylindrical shape, and the ventilation pipe 6 is formed by partitioning the inside thereof. The container body 1 of the liquid container is tilted in a certain direction as shown in FIG. 3 for pouring or sucking. When the entire liquid container is tilted as shown in FIG. 3, the content liquid flows out of the vessel through the lower side of the extraction pipe 5 as indicated by the black arrow in the figure, and the content liquid flows as indicated by the white arrow. In the opposite direction, air flows into the vessel. Then, the portion above the inclination for pouring, that is, the right side of the drawing of the embodiment shown in FIG. 1 and FIG. 4, passes to the inside of the circular cross section of the pouring pipe 5 that is a circular cross section. A trachea 6 is formed. Therefore, the vent pipe 6 is formed inside the pouring pipe 5. The dispensing tube 5 is not necessarily cylindrical as long as it is cylindrical, but it is preferable to use a cylindrical shape as a liquid injection port or a drinking port in consideration of the uniform sealing property by the packing 21.

  The upper end of the vent pipe 6 formed inside the extraction pipe 5 is positioned inward of the outlet 5a. Thereby, when a part of packing 21 attached to the cap 7 enters the inside of the extraction pipe 5, it does not collide. However, when the container main body 1 is tilted, the inflow of air becomes smooth when the water level is located below the opening of the vent pipe 6. Therefore, it is preferable that the upper end of the vent pipe 6 is as close as possible to the spout 5a. For example, the open end of the vent pipe 6 is formed inwardly to the same dimension as the diameter of the spout pipe 5. However, even if it is deeper inside than this, the air that has entered the container along the inner surface of the extraction pipe 5 passes through the vent pipe 6 portion, so that compared with a conventional liquid container without a vent pipe. And has a smooth injection effect. Note that the vent pipe 6 is formed so that the tip of the vent pipe 6 extends to the tip of the extraction pipe 5 because it acts to send air into the container.

  In addition, it is also conceivable to form an air groove through which air passes, for example, as a concave groove in the circumferential direction at the back of the extraction pipe 5, but in this case, the liquid that is discharged through the extraction pipe, The separation from the air entering in the opposite direction becomes incomplete in the extraction pipe, and the effect of smoothly sending air into the vessel is reduced. In particular, the effect of smoothly pouring out is extremely reduced when the air groove is used with an inclination such that the air groove is submerged in the liquid during pouring or sucking. Therefore, the present invention is characterized in that the vent pipe 6 is formed in the pouring pipe 5 to completely separate the portion through which the content liquid passes from the portion through which air passes. Thereby, the liquid container which has the remarkable effect which can pour out a content liquid smoothly can be implement | achieved.

  The liquid container of the embodiment shown in FIGS. 1 to 5 is a liquid container having a relatively large capacity, and is brought close to one side of the stopper 4 and the stopper cover 3 having a large diameter, and the outlet pipe 5 and the outlet pipe support cylinder. 17 is formed, and a relatively small cap 7 corresponding to a size of a part of the top surface of the plug cover is disposed on the top surface of the plug cover 3 so as to be freely opened and closed. On the other hand, in the liquid container of the embodiment shown in FIGS. 6 and 7, the pouring pipe 5 is disposed at the center position of the stopper 4, and the pouring pipe support cylinder 17 is disposed at the center position of the stopper cover 3. A cap 7 having a size covering the entire top surface of the stopper cover 3 is pivotally supported at the rear end portion of the stopper cover 3. However, the liquid container shown in FIG. 1 and the liquid container shown in FIG. 6 have the same basic configuration.

  That is, a plug 4 is installed in which the packing 18 attached to the lower end of the stopper 4 is in close contact with the throttle portion 8a of the vacuum double bottle 8 and maintains a watertight state. The stopper 4 is attached by a stopper cover attached to the container body 1. Retained. The pouring pipe 5 of the plug 4 and the pouring pipe support cylinder 17 of the plug cover 3 can be moved freely in the axial direction. Further, the spout 5a is sealed by being brought into contact with the lower surface of the outer casing 22 of the packing 21. As a result, a change in the position of the stopper 4 and the position of the stopper cover 3 is allowed, and a liquid container capable of maintaining a complete sealed state regardless of assembly or dimensional errors of parts is realized. As described above, in any of the illustrated embodiments, since the stopper 4 and the stopper cover 3 can be separated and removed, the entire interior including the inner part of the vent pipe 6 can be easily cleaned.
