  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  The liquid discharge container according to the embodiment will be described with reference to FIGS.

  As shown in FIGS. 1 to 2, in the liquid discharge container, the mouth portion 10 a of the container body 10, which is a rotating body with a closed bottom, is formed on one side in the axial direction of the container body 10 so as to have a smaller diameter than the other. . In the following description, in the liquid discharge container, the direction in which the mouth portion 10a is formed along the axial direction is referred to as the front, and conversely, the direction with the bottom is referred to as the rear.

  The liquid discharge container is a container provided with a push-type inner plug 12 that opens the valve body 14 and allows the liquid in the container to be discharged by pressing the tip of the inner plug 12 provided in the mouth portion 10a of the container body 10. It is about.

  The inner plug 12 is provided with an air introduction path 16 capable of introducing air into the container separately from the valve body 14.

  A finger hook lever 18 is provided at the tip of the push-type inner plug 12. The air introduction path 16 has a tube body whose one end is connected to the outside of the container body 10 and whose other end is opened in the bottom of the container body 10. The air introduction path 16 is provided with a check valve 20.

  Specifically, the container body 10 is in a non-use stationary state shown in FIG. 1 and has a generally circular or oval cross section from the center to the bottom, and the bottom is closed. The mouth part 10a (upper part in FIG. 1) is formed to have a slightly smaller diameter than the center part.

  The mouth portion 10a of the container body 10 is closed from the front with a generally bowl-shaped or tubular inner plug 12.

[Inner plug 12]
The inner plug 12 has a shape in which a large-diameter cylindrical portion 12a that is open toward the rear and a small-diameter cylindrical portion 12b that is open toward the front are continuous with the partition wall 12c as a boundary. Although the wall 12c is a partition inside, the front portion of the large-diameter cylindrical portion 12a is closed at a portion protruding from the small-diameter cylindrical portion 12b to form a shoulder portion.

  The large-diameter cylindrical portion 12 a is fitted into the mouth portion 10 a at the front end of the container body 10. The fitting part of the outer peripheral surface part of the large-diameter cylindrical part 12a is detachably fitted to the tip of the mouth part 10a so that the inner plug 12 is attached to the mouth part 10a. Moreover, the valve body 14 is fitted in the small diameter cylindrical portion 12b so as to be movable forward and backward.

[Valve 14]
The valve body 14 is formed by fitting and connecting a hollow cylindrical portion 14a (cylinder main body 14a1) at the front portion and an umbrella-shaped valve portion 14b (valve main body 14b1) at the rear portion. The front tube portion 14a is provided with a finger-hanging lever 18 having an enlarged diameter on the outer surface thereof at the outer surface portion, and a diameter-enlarged portion 14a2 formed in a downward-opening skirt shape is provided at the rear of the finger-hanging lever 18. The surface is provided in the small diameter cylindrical portion 12b so as to be slidable back and forth. The diameter-enlarged portion 14a2 is provided with a seal portion such as an O (O) ring on the outer peripheral surface so as to be in sliding contact with the inside of the small-diameter cylindrical portion 12b. Therefore, the seal portion prevents the liquid between the inner plug 12 and the valve body 14 from leaking from other than the opening at the end of the cylindrical portion 14a.

  The lower valve portion 14b has a shaft-shaped valve body 14b1 that is continuous with the front end fitted to the cylindrical portion 14a, and the plate-like portion 14b2 is deployed at the rear end of the valve body 14b1 and located inside the container body 10b. It is what. The hollow of the valve body 14b1 has a front end communicating with the hollow of the cylindrical portion 14a, an open side, and a rear end closed by a plate-like portion 14b2.

  An insertion hole 12c1 and a liquid passage hole 12c2 pass through the partition wall 12c of the inner plug 12. The valve main body 14b1 is inserted into the partition wall 12c insertion hole 12c1, and the plate-like portion 14b2 of the valve portion 14b is separated from and contacts the partition wall 12c, thereby opening and closing the liquid passage hole 12c2. It has a structure.

  A spring 22 is disposed between the front surface of the partition wall 12c and the rear surface of the cylindrical portion 14a, and the valve body 14 is urged forward by the elastic force of the spring 22, so that it is not pressed. In general, the plate-like portion 14b2 of the valve portion 14b closes the liquid passage hole 12c2.

[Air introduction path 16]
The partition wall 12c that connects the large-diameter cylindrical portion 12a and the small-diameter cylindrical portion 12b of the inner plug 12 is a portion where the portion extending to the front end of the large-diameter cylindrical portion 12a is formed wider than the small-diameter cylindrical portion 12b. The opening 16a of the air introduction path 16 is opened toward the front at the shoulder.

  A check valve 20 is provided in the opening 16a. The check valve 20 has a cylindrical holder extending from the opening 16a at the shoulder of the large-diameter cylindrical portion 12a, and a ball-shaped valve body 20b is movably accommodated in the holder 20a.

  The holder 20a is made of a resin material, and the valve body 20b is made of metal such as stainless steel or resin, and is made of a material that does not change in quality with the content liquid.

  Moreover, in order to maintain airtightness, the chamfering or the elastomer is arrange | positioned in the location where the valve body 20b of the opening part 16a contacts. As shown in FIG. 1, when the container has its mouth portion 10a facing upward, the valve body 20b is in close contact with the opening 16a, the check valve 20 is closed, and conversely, as shown in FIG. As described above, when the mouth portion 10a is directed downward, the valve body 20b is detached from the opening portion 16a and the check valve 20 is opened. At this time, since the holder 20a is provided, the valve body 20b does not come off the check valve 20.

  The air introduction path 16 has a tube body extending from the opening 16 a toward the bottom of the container body 10. The tube body may be made of the same material as the container body 10 made of a resin material or a different material. In terms of molding and handling of the tube body, an elastic material is preferable.

[Operation of valve body 14 in liquid discharge container]
In the liquid discharge container of the embodiment, as shown in FIG. 2A, when discharging the liquid, the user puts a finger on the finger hook lever 18 and presses it toward the container body 10 to resist the resilience of the spring 22. Then, the valve body 14 is pushed in.

At the same time, the tip of the valve body 14 is directed downward and directed toward the use location.
When the valve body 14 is pushed in, the plate-like portion 14b2 of the valve portion 14b opens the liquid passage hole 12c2. Then, the liquid in the container body 10 enters the hollow of the valve body 14b1 from the liquid passage hole 12c2 through the hole on the side of the valve body 14b1 by its own weight, and from the front end of the tubular part 14a through the hollow of the front tubular part 14a. Flow out.

  At the same time, in the check valve 20, the valve body 20 b moves downward due to its own weight, the check valve 20 is opened, and air is introduced into the container body 10 through the air introduction path 16. Therefore, when the content liquid is discharged from the cylindrical portion 14a of the valve body 14, the air smoothly flows into the container body 10 and can be continuously discharged without squeezing.

  Further, by providing the finger hook lever 18 at the tip of the push-type inner stopper 12, the inner stopper 12 is easy to operate, and the contents are continuously displayed while the inner stopper 12 is being opened by the finger hook lever 18. Liquid can be dispensed. Like the embodiment shown in FIG. 2A, the user can discharge the content liquid by operating the finger hanging lever 18 with the tip of the valve body 14 directed downward at an appropriate position, which is convenient. On the other hand, as shown in FIG. 2 (b), the one without the finger-lever 18 is also within the scope of the present invention. However, it is necessary to press the tip of the valve body 14 downward to the place of use. It is necessary to be mindful of sliding to operate the valve body 14 when it is hung down. The liquid discharge container shown in FIG. 2 (a) allows easy operation by the finger-holding lever 18, so that it is possible to adjust the discharge amount more delicately than that shown in FIG. To do.

  Further, since the air introduction path 16 has a tube body in which one end is connected to the outside of the container body 10 and the other end is opened in the bottom part of the container body 10, Air can be introduced smoothly.

  Here, a liquid discharge container of a comparative example in which the air introduction path 16 is not provided is shown in FIG. 3B (in the comparative example, the same reference numerals are given to the same parts as in the embodiment). As shown in FIG. 3 (b), in the comparative example, when the valve body 14 is opened by pulling the finger hanging lever 18 with the mouth portion 10a of the container main body 10 facing downward, the liquid in the container main body 10 is removed. It tries to flow out from the tip of the cylinder part 14a by its own weight. At this time, the pressure in the container main body 10 decreases due to the decrease in the liquid in the container main body 10 due to the liquid discharge, and the liquid flow stops or hardly flows due to factors such as the viscosity of the content liquid as it is. Was pumped (squeezed) to introduce outside air from the tip of the cylindrical portion 14a to balance the pressure drop in the container body 10. That is, in the discharge container as in the comparative example, there is a case where it is difficult to smoothly discharge liquid because it is necessary to alternately repeat liquid discharge and air introduction (air replacement).

  On the other hand, in the liquid discharge container of the embodiment, as shown in FIG. 3A, when the valve body 14 is opened by pulling the finger hanging lever 18 with the mouth portion 10a of the container body 10 facing downward. The liquid in the container main body 10 tends to flow out from the tip of the cylinder part 14a by its own weight, but the internal pressure is reduced, but at the same time, outside air is introduced from the air introduction path 16, and the internal pressure is balanced. Therefore, the liquid discharge can be continuously performed smoothly and is easy to use.

  Further, since the check valve 20 is provided in the air introduction path 16, the container main body 10 is shut off from the outside air during normal times when the front end of the container is not directed downward, such as in a stationary state. 10 is turned upside down and is opened only during use when the finger-lapping lever 18 is pulled, so that contents protection and liquid leakage prevention effects can be expected.

  The configuration of the above-described embodiment is preferable in the present invention, but of course, the present invention is not limited thereto, and various modifications can be made within the scope of the present invention.

[Modification 1]
For example, Modification 1 is shown in FIG. As shown in FIG. 4, in the first modification, the air introduction path 16 is changed to the check valve 20 of the embodiment, and to the inner plug 12 that presses the valve body 14 at the distal end of the inner plug 12 by operating the finger latch lever 18. Is provided with an on-off valve structure 24 that allows air to be introduced into the air introduction path 16.

  Specifically, as shown in FIG. 4, the on-off valve structure 24 is provided with a plate-like portion 14b2 of the valve body 14 that moves back and forth in the inner plug 12 extending in a plane direction, and a cylindrical valve portion 24a fixed thereto. In addition, an opening / closing hole 24b that opens to the outside is formed in the shoulder portion of the large-diameter cylindrical portion 12a.

  The tubular valve portion 24a is a hollow tube, and a rod-shaped portion 24a1 is formed so as to project forward from the inside of the hollow tube in a state where communication between the front and rear of the valve portion 24a is ensured. Further, a tubular fixing portion is formed to protrude behind the valve portion 24a, and an air introduction path 16 made of a tube body is fitted into the cylindrical fixing portion.

  The opening / closing hole 24b has a smaller inner diameter from the rear to the front than the center, and the valve 24a is slidably fitted from the rear to the center. When the valve portion 24a is positioned at the front end, the rod-like portion 24a1 is fitted into the narrow front portion of the opening / closing hole 24b, and the opening / closing hole 24b is closed.

  In addition, a positioning rod that protrudes backward from the partition wall 12c is moved back and forth in the restriction hole 14b3 formed in the plate-like portion 14b2 so that the valve body 14 moves back and forth within the inner plug 12 without rotating. Fits freely. As a result, the rotation of the valve body 14 in the inner plug 12 is restricted, so that the insertion / removal operation of the valve portion 24a with respect to the opening / closing hole 24b can be reliably performed without being displaced.

  When not in operation, as shown in FIGS. 4A and 4B, the valve element 14 is not operated in the inner plug 12, so that the valve portion 24a of the open / close valve structure 24 is also fitted in the open / close hole 24b. Is closed.

  At the time of operation, as shown in FIGS. 4 (c) and 4 (d), the finger lever 18 is operated to cause the valve element 14 to move backward in the inner plug 12, and the plate-like portion 14b2 opens the liquid passage hole 12c2. . The liquid flows into the cylinder body 14a1 and is discharged from the tip of the cylinder portion 14a.

  At the same time, the valve portion 24a of the open / close valve structure 24 also moves rearwardly in the open / close hole 24b, the rod-like portion 24a1 is detached from the small front portion of the open / close hole 24b, and the open / close hole 24b is opened. Even if outside air is introduced into the container main body 10 from the opening / closing hole 24b through the air introduction path 16 and liquid is discharged from the tip of the cylindrical portion 14a, the inside of the container main body 10 does not become negative pressure, and air replacement is continuously performed. As it is performed, the liquid is discharged smoothly and continuously.

  Therefore, in the first modification, the air introduction path 16 is provided with the opening / closing valve structure 24 that allows air to be introduced into the air introduction path 16 by opening the inner plug by pressing the tip of the inner plug. Since the air is introduced into the air introduction passage 16 only when the inner plug 12 is operated, the air is surely introduced only when the finger hook lever 18 is operated, and the air is surely introduced when it is not operated. Therefore, it is possible to prevent liquid leakage due to inadvertent introduction of air.

[Modification 2]
Next, a second modification of the embodiment will be described with reference to FIG.

  In the second modification, the container body 10 is formed of a material such as a transparent or translucent resin so that the liquid level inside is visible. At the same time, a scale 26 that can be compared with the liquid surface is provided. The scale 26 is shaken along the axial direction of the container main body 10 according to the amount of the liquid content, and is appropriately formed on the container main body by printing or forming irregularities.

  According to the second modification, the container body 10 is squeezed by making the container body 10 transparent or translucent so that the inner liquid level is visible and provided with a scale 26 that can be compared with the liquid level. When discharging a large-capacity content liquid without any problems, the scale 26 can be shaken in the bottle and used while confirming the discharge amount. In addition, it is easy to check the remaining amount.

  The liquid discharge container of the present invention can be used not only for household liquid products such as cosmetics, detergents and softeners, but also for industrial liquid products such as adhesives, sealants and glues.
