Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a liquid metering dispenser for metering and dispensing a fixed amount of liquid medicine such as a mouthwash and a cold medicine.

"Prior Art" Various types of distributors have been conventionally provided as this type of distributor, and among them, a measuring cup connected to the container body by a suction pipe is arranged at the container mouth to A squeeze type structure is typically used in which the liquid is squeezed and sent out through the suction pipe to a measuring cup for weighing, and then the container is tilted and poured out from the measuring cup.

[Problems to be Solved by the Invention] According to the above conventional structure, the structure and operation are relatively simple, but there are the following problems.

That is, a suction pipe hangs down from the measuring chamber to the bottom of the container body, and this suction pipe contains the liquid at the same level as the liquid in the container body. When pouring out, the liquid in the suction pipe is also poured out. The amount of liquid in the suction pipe changes in accordance with the change in the amount of liquid in the container due to distribution, so that the amount of liquid in the suction pipe is piled up and the amount of the measured liquid poured out to the outside varies. become.

According to the present invention, a temporary storage chamber is provided at the front stage of the measuring chamber, the suction pipe is hung from the temporary storage chamber to the bottom of the container body, and the liquid in the suction pipe is stored in the temporary storage chamber during external pouring,
The object is to obtain a highly reliable liquid dispenser which is prevented from being poured out to the outside so that the amount of the outside pouring does not vary.

"Means for Solving the Problem" The liquid dispenser of the present invention is equipped with a container body 1 having a squeezable body portion 5 and a mouth / neck portion 6 of the container body 1, and a plug for closing the container body opening. A top plate, which is an inverted cup shape made of a transparent body, and an inner stopper 2 penetratingly erected through a liquid introducing cylinder 9 having an opening 8 for defining the weighing level "a" above the center of the plate 7
10 A pouring hole 11 is opened in the central part, and a canopy 13 having a stopper body 12 which is inserted into the pouring hole 11 is hung on the upper surface of the top plate 10 so as to be opened and closed. A chamber communicating with the measuring chamber 14 via the liquid introducing cylinder 9 and the measuring chamber member 3 disposed on the upper surface of the stopper plate 7 is formed so that the measuring chamber 14 whose bottom plate is the second stopper plate 7 is formed. Thus, the temporary storage chamber 4 is attached to the back surface of the stopper plate 7 of the inner stopper 2 and has a suction pipe 15 that hangs downward from the bottom of the container body 1.

[Operation] In the above, during the dispensing, the lid and lid are always closed as shown in FIG. 1, and the canopy 13 is opened and the pouring hole 11 is opened as shown in FIG. While visually observing through the chamber member 3, the container body 5 is squeezed to suck up the liquid in the container body 1 through the pipe 15, the temporary storage chamber 4, and the liquid introducing cylinder 9, and the measuring chamber of the measuring chamber member 3. Install within 14 In this case, the introduced liquid exceeding the level "a" returns to the inside of the container body 1 from the opening 8 through the liquid introducing cylinder 9 and the temporary storage chamber 4, so that a certain amount of the level "a" is measured.

After the measurement is completed, the container is turned downward as shown in FIG. 3, the container body 5 is squeezed again, and the measuring liquid in the measuring chamber 14 is pressurized and poured out from the pouring hole 11 to the outside. In this case, the liquid in the suction pipe 15 at the same level as in the container body 1 is also sent out downward, but the amount thereof is small, so that it is sent into the temporary storage chamber 4 and into the measuring chamber 14. Therefore, it is not piled up in the amount of pouring out to the outside. That is, the amount of pouring out to the outside is limited to a fixed amount in the measuring chamber 14,
No variation occurs.

Since the spout hole 11 is a small-diameter opening and the measuring liquid is spouted under pressure from the spout hole 11, the liquid is well drained and therefore the liquid does not drip.

[Embodiment] An embodiment will be described below with reference to the drawings. In the present invention, a temporary storage chamber 4 is provided in front of a measuring chamber 14, and a suction pipe 15 is provided from the temporary storage chamber 4 to the bottom of the container body 1. It has a feature in that the liquid in the suction pipe 15 is temporarily stored in the storage chamber 4 at the time of external pouring so as not to be externally poured out so that there is no variation in the external pouring amount. The container body 1, the inner plug 2, the measuring chamber member 3, and the temporary storage chamber 4 are included.

The container body 1 is provided with a mouth-neck portion 6 standing upright from the upper end of the elastically deformable body portion 5 and having an external thread.

The inner stopper 2 has a cap-like shape, and a central portion excluding the peripheral portion of the stopper plate 7 that closes the opening of the container body 1 is projected upward, and a mounting peripheral wall 16 hung vertically from the peripheral edge of the stopper plate 7. Is attached to the outer surface of the mouth / neck portion 6 by screwing, and at the central portion of the stopper plate 7, a liquid introduction cylinder 9 with an upper bottom having several openings 8 in the circumferential direction opened at the upper portion is erected through. Moreover, the liquid introducing cylinder 9 is attached to the stopper plate 7.
An upper mounting peripheral wall 17 is provided extending downwardly from the peripheral edge of the stopper plate 7 and a thread groove is provided on the inner surface of the stopper plate 7, and an engaging projection 18 is provided on the inner surface from the rear surface of the stopper plate 7. Mouth and neck 6
A ring plug 19 that is fitted inside is hung.

The measuring chamber member 3 is made of a transparent material and is a reverse cup-shaped member in which the top plate 10 is curved upward in an arc shape, and a pouring hole is provided at the top of the top plate 10.
A canopy with an opening 11 and an arcuate shape in which a plug 12 for opening and closing the pouring hole 11 is hung in the upper surface of the top plate 10 in the center of the back surface.
13 is integrally provided by thin-walled three-point hinges 20a, 20b, 20c on the rear side. That is, the canopy 13 is a well-known three-point support type elastic inversion type. Then, a screw thread is formed on the lower outer surface of the peripheral wall 21, and the screw thread is screwed into the screw groove to attach the upper mounting peripheral wall.
It is attached to 17. Therefore, the measuring chamber member 3 forms a measuring chamber 14 in which the stopper plate 7 of the inner stopper 2 serves as a bottom plate.

Since the elastic reversing mechanism is very well known, it will be briefly described. From the rear of the canopy 13 to the upper part of the peripheral wall 21, the elastic reversing plate 22 having an inverted L shape is provided.
Are separated from each other, and the fulcrum hinge 20b of the canopy 13 and the elastic inversion plate 22 are separated.
The fulcrum hinge 20c is displaced, and the hinge 20a is used as a common rotary hinge. Either of the closed lid and the stopper shown in FIG. 1 or the opened lid and the stopper shown in FIG. 2 and FIG. Even in this state, the canopy 13 is located at the stable point and is stably held. It is preferable that the canopy 13 is of an elastic inversion type because of its structure, but in this case, it is not limited to the three-point hinge type, and is not necessarily limited to the elastic inversion type.

The temporary storage chamber 4 is of a deformed cup shape, and the bottom plate 23 is inclined so that the central portion on the rear side (right side in the drawing) is at the lowest position, and the through hole 24 is opened at this lowest position. A connecting cylinder 25 is hung from the lower surface, a suction pipe 15 communicating with and connected to the connecting cylinder 25 is hung downward in the container body 1, and an engaging projection 26 on the outer surface of the upper end is engaged with the engaging projection 18. Together, they are internally fitted and fixed to the ring stopper 19, and the stopper plate 7 is used as a top plate to form a storage chamber communicating with the measuring chamber 14.

Therefore, according to the above-mentioned embodiment, a certain amount of liquid can be measured by squeezing the container body 5, and after this measurement, the container is turned downward and the container body 5 is squeezed again to discharge the measured liquid to the outside. Since the liquid in the suction pipe 15 is temporarily sent to the storage chamber 4 and not to the measuring chamber 14 in this case, the pouring amount to the outside is limited to a fixed amount in the measuring chamber 14. Therefore, there is no variation in the external pouring amount. Further, since the measuring liquid is poured out to the outside under pressure, the liquid is well drained, the liquid does not drip, and the measuring and pouring state can be seen through the measuring chamber member 3, which is convenient.

Each of the above parts is molded and manufactured from a synthetic resin material.

[Advantage of the Invention] As described above, in the present invention, the temporary storage chamber 4 is provided in front of the measuring chamber 14, and the suction pipe 15 is hung from the temporary storage chamber 4 to the bottom of the container body 1 and sucked when pouring to the outside. Since the liquid in the pipe 15 is temporarily stored in the storage chamber 4 so as not to be poured out to the outside, only a fixed amount weighed in the measuring chamber 14 can be always poured out, and the amount of external pouring does not vary, A highly reliable liquid dispenser can be provided. Further, in this dispenser, the measuring chamber member 3 is of a pouring plug type made of a transparent body, and the measuring liquid is poured out from the small-diameter pouring hole 11 by pressure pouring, so that the liquid is well drained, and therefore no liquid dripping occurs. There are advantages.
