In another aspect, the main body member has an air introduction pipe for introducing external air into the container, the air introduction pipe is formed of a soft material, and is provided at the other end of the air introduction pipe. Is provided with a float, and a weight for submerging the lower side of the float in the liquid is provided at the lower part of the float. The air introduction pipe may be detachable from the main body member. Preferably, the weight is housed in the float.
That is, since the air introduction pipe is soft and deformable, the air introduction pipe must be put in the container prior to the attachment to the spout, but at that time, without changing the direction of the main body member in a complicated manner, The mounting posture can be straightened, and mounting work can be easily performed. In addition, since the air introduction tube is rolled into a hoop shape, for example, it becomes a compact form, so that there is an advantage that it is convenient for handling such as transportation and management and the cost can be reduced. In addition, since the lower part of the float is submerged in the liquid, the float floats in the liquid in a certain direction. For this reason, the direction of the other end of the air introduction tube can be made constant. In other words, since the other end of the air introduction pipe can be regulated upward, the intended purpose of the air introduction pipe can be achieved.

In another aspect, the main body member is provided with an indicator indicating the liquid level in the container. The indicator is preferably removable.
That is, since the indicator displays the remaining amount of liquid in the container, the use becomes more convenient.

  As described above, according to the present invention, attachment is possible regardless of the shape of the outlet of the container, and the attachment work is also simple.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a partially broken side view showing a use state in which a liquid discharge tool 11 is attached to a funnel can 12 as an example of a container. As shown in FIG. The liquid 13 from 12 can be discharged easily and smoothly.

  FIG. 2 is a cross-sectional view showing the overall structure of the liquid discharge tool 11, and a main body member 14 having a lead-out path for discharging the liquid 13 and air for introducing the air into the canister 12 when the liquid 13 is discharged. It has an air introduction pipe 15 and an indicator 16 indicating the liquid level in the funnel can 12, and the attachment portion 21 on the base side of the main body member 14 is attached to a spout 12 a formed on the top surface of the funnel can 12. It is done.

  It should be noted that the spout 12a may be any one that is appropriately opened during use or one that is formed in advance in a predetermined shape.

First, the main body member 14 will be described.
The main body member 14 has a large-diameter mounting shaft portion 22 on the base side and a smaller-diameter outlet tube portion 23, and the outlet tube portion 23 is eccentric with respect to the mounting shaft portion 22, that is, on the lower side. It is arranged in a row. And the front-end | tip of the derivation | leading-out pipe part 23 is bent toward the downward direction, and the discharge outlet 24 is formed. A switching lever 25 for switching between opening and closing is provided on the upstream side of the discharge port 24.

  As shown in FIG. 3, the attachment shaft portion 22 has a short cylindrical shape having a hook-like hook-like portion 26 extending in the outer peripheral direction at the base end thereof. The size (diameter) of the portion having the bowl-shaped portion 26 is a size that can be inserted into the spout 12 a of the one-hole can 12. A male screw 27 is formed on the outer peripheral surface of the mounting shaft portion 22.

  An annular elastic seal member 28 is inserted into the male screw 27 portion, and the elastic seal member 28 is compressed to the flange-like portion 26 side so as to be expanded in diameter to be pressed against the mouth edge of the spout 12a. An annular fastening member 29 that is sealed by being screwed is screwed together. The portion of the elastic seal member 28 on the hook-like portion 26 side may be fixed in advance to the hook-like portion 26 by appropriate means such as an adhesive. This is because the elastic seal member 28 does not unexpectedly disengage from the bowl-shaped portion 26 and the elastic seal member 28 can be reliably expanded in diameter. In the figure, 29a is a female screw screwed into the male screw, and 30 is a washer. Further, the washer 30 and the fastening member 29 are formed to have a larger diameter than the elastic seal member 28.

  Further, a small hole 31 penetrating inward and outward is formed in the front surface of the mounting shaft portion 22 in the main body member 14, and a screw hole 32 penetrating inward and outward is formed in the upper surface on the upstream side of the switching lever 25. ing. The air introduction pipe 15 is fixed to the small hole 31, and the indicator 16 is detachably attached to the screw hole 32.

  The air introduction tube 15 is formed of a soft synthetic resin or the like, and one end thereof is detachably fixed to the small hole 31. A male screw 41 and a slit-shaped air intake groove 42 are formed at one end, and a nut 43 and an opening / closing cap 44 are screwed into the male screw 41 portion. The air intake groove 42 can be opened and closed by tightening or loosening the opening / closing cap 44.

  On the other hand, a hollow float 45 is provided at the other end of the air introduction tube 15 (see FIG. 2). The float 45 has a substantially spherical shape with a flat surface on the bottom surface, and the air introduction pipe 15 is connected to the side surface thereof. The air introduction pipe 15 is bent in an L shape within the float 45, and the opening 15 a at the other end is exposed on the upper surface of the float 45. The opening 15 a may protrude from the upper surface of the float 45.

  In addition, when the air introduction pipe | tube 15 is unnecessary, it is good to equip the small hole 31 with the plug member which is not shown in figure so that it can be used without the air introduction pipe | tube 15.

  The indicator 16 is in the shape of a pipe made of a transparent material, and a male screw 16a that is screwed into the female screw of the screw hole 32 is formed at the lower end thereof. A stopper 16b is provided above the male screw 16a. In addition, when the indicator 16 is unnecessary, it is good to equip the screw hole 32 with the plug member which is not shown in figure so that it can be used without an indicator.

The liquid discharge tool 11 having such a configuration is attached to the Ito can 12 as follows.
First, as shown in FIG. 4, the elastic seal member 28 is inserted into the male screw 27 portion of the mounting shaft portion 22 of the main body member 14, and at least a part of the tightening member 29 is screwed into the mounting shaft. The portion 22 is inserted so as to face the spout 12 a of the Ito can 12. At this time, the air introduction tube 15 is attached to the main body member. When used without the air introduction tube 15, an air introduction hole (not shown) is opened on the side of the spout 12 a on the top surface of the canister 12.

  The elastic seal member 28 is supported by hand so as to be located inside the spout 12a, and the direction of the discharge port 24 of the main body member 14 is set to a desired direction, and then the fastening member 29 is rotated to be elastic. If the sealing member 28 is pressed against the hook-like portion 26 and compressed, the elastic sealing member 28 is expanded in diameter as shown in FIG. 2, and its outer peripheral surface is pressed against the edge of the spout 12a. The liquid discharger 11 can be attached to the canister 12 and the sealing is completed. The indicator 16 may be attached to the screw hole 32 of the main body member 14 after the attaching operation.

  As described above, since the elastic seal member 28 is attached in pressure contact with the edge of the spout 12a, a certain difference in shape and size of the edge can be absorbed. Moreover, if the elastic seal member 28 having different thicknesses is used as shown by phantom lines in FIG. 3, the range of applicable spouts 12a is expanded. That is, attachment is possible irrespective of the shape of the spout 12a of the one-piece can 12. Moreover, the installation work is simple.

  Since the air introduction pipe 15 made of a soft material is provided and a float 45 is provided at the other end, the air introduction pipe 15 is put in the canister 12 prior to attachment to the spout 12a. However, at that time, it is possible to make the mounting posture straight without easily changing the direction of the main body member, and the mounting work can be easily performed. Further, since the air introduction pipe 15 is rolled into a compact form, for example, it is convenient for handling such as transportation and management, and has an advantage that the cost can be suppressed.

  In addition, since the weight 46 that sinks the lower side of the float 45 in the liquid is accommodated in the lower part of the float 45 and the opening 15a at the other end of the air introduction pipe 15 is restricted so as to face upward. The intended purpose of the introduction pipe 15 can be reliably achieved.

  In addition, since the float 45 has a flat surface at the bottom and is connected to the air introduction pipe 15 from the side surface of the float 45, the float 45 falls over even if the amount of the liquid 13 in the canister 12 decreases. The opening 15a of the air introduction tube 15 can always be directed upward.

  Furthermore, since the indicator 16 is provided, the remaining amount of the liquid 13 in the canister 12 can be known, and the use becomes more convenient.

Hereinafter, other embodiments will be described. Note that components that are the same as or equivalent to the components described above are given the same reference numerals, and detailed descriptions thereof are omitted.
FIG. 5 shows an example in which a hook-shaped contact portion 51 that contacts the outer surface of the mouth edge of the spout 12 a is formed on the elastic seal member 28. That is, a contact portion 51 that protrudes to the outer periphery is formed at the tip of the elastic seal member 28 having a short cylindrical shape. Further, a tapered surface 52 is formed on the inner peripheral surface of the rear end (base end) portion of the elastic seal member 28 so that the rear end has a larger diameter. The tapered surface 52 is formed in accordance with the inclined surface 26a provided in the flange-shaped portion 26 of the main body member 14, and when compressed by the fastening member 29, as shown in FIG. The rear end side portion 28 is expanded outward so that the diameter for sealing is increased.

  When the elastic seal member 28 has the contact portion 51 as described above, the contact portion 51 of the elastic seal member 28 hits the outer peripheral surface of the lip of the spout 12a when attached to the spout 12a. The main body member 14 can be easily supported when the member 29 is operated.

  FIG. 7 shows another example of a mode in which the elastic seal member 28 is deformed. That is, the elastic seal member 28 is deformed so as to sandwich the mouth edge of the spout 12 a inside and outside when compressed by the fastening member 29.

  That is, the elastic seal member 28 has a contact portion 51 as in the elastic seal member 28 shown in FIG. Then, a notch 53 is formed on the inner side surface of the intermediate portion in the longitudinal direction, and when the elastic seal member 28 is compressed toward the flange 26 side of the main body member 14, the notch as shown in FIG. The part corresponding to 53 is deformed so as to rise in the outer circumferential direction.

  FIG. 9 shows another example of the float 45. That is, the float 45 is formed in a substantially long cross-sectional saddle shape with a flat bottom surface as shown in FIG. An opening 15 a at the other end of the air introduction pipe 15 that enters from one end surface of the float 45 is exposed at one end of the curved upper surface of the float 45. The shape of the opening 15a is formed so as to curve along the upper surface of the float 45 [see FIG. 9B].

  In addition, since the amount of the liquid 13 is large at the start of use, the upper surface of the float 45 is close to the ceiling surface 12b in the Ito can 12, but the opening 15a of the air introduction tube 15 is curved when viewed from the side. Therefore, even if the float 45 hits the ceiling surface 12b, a gap t is formed. For this reason, there is no possibility that the opening portion of the air introduction tube 15 is in close contact with the ceiling surface 12a. Therefore, the air flow is not hindered, and the intended purpose of the air introduction pipe 15 can be reliably achieved.

In the correspondence between the configuration of the present invention and the configuration of the above-described embodiment,
The container of the present invention corresponds to the above-mentioned Ito can ,
The pressure contact portion corresponds to the contact portion 51,
The present invention is not limited to the above configuration, and various other forms can be adopted.
For example, the present invention can be applied to various cans other than Ito cans and synthetic resin containers. Further, the tightening member may be configured not only to be screwed as described above, but also to be configured so as to be prevented from coming off by simply being pushed in and rotated.
