2. Description of the Related Art Conventionally, cosmetics and other chemical liquids have been mainly inorganic chemical liquids, but in recent years, many liquid chemicals contain organic substances such as proteins, and the chemical liquids containing such organic substances remain uncapped. If left unattended, bacteria will multiply inside, which is a problem.Therefore, it is opened at the time of use, and usually, for example, after removing the rubber cap of the container, sucking out the drug solution contained inside with a dropper, After removing the rubber cap, a perforated drip cap was attached to the mouth of the container for use.

[0003]

However, it takes a lot of time to attach such a cap with a hole or to use a dropper, and when removing or attaching the cap or using the dropper, the chemical solution inside the container must be removed. It was a problem because it could become contaminated.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a drip vial cap in which the cap can be easily removed and attached and the drug solution contained in the container is not contaminated. To aim.

[0005]

In order to solve the above-mentioned problems, the present invention solves the above-mentioned problems by providing a rubber stopper having a through hole formed on a shaft, and a liquid removal member slidably inserted in the through hole of the rubber stopper. A nozzle, a caulking member for fixing the rubber stopper to the mouth portion of the vial, the rubber stopper attached to the vial, a liquid extraction nozzle, and a caulking member, which is capped on the mouth portion of the vial,
The liquid take-out nozzle comprises a cap member that is detachably engaged with the liquid take-out nozzle, and the liquid take-out nozzle has an engaging means for engaging with the cap member at an upper end thereof. A nozzle seals a through hole of the rubber stopper, and a liquid that connects the inside of the vial and the liquid outlet of the liquid outlet nozzle between the liquid outlet nozzle and the rubber stopper at a slide upper limit position of the liquid outlet nozzle. A drip vial cap with a passage is used.

Here, the liquid passage is formed in a wide annular groove formed in the middle of the through hole of the rubber stopper, a communication hole formed in the middle of the liquid take-out nozzle, and a lower portion of the liquid take-out nozzle. The communication hole may communicate the annular groove and the liquid outlet at least at the slide upper limit position, and the vertical groove may communicate the inside of the vial and the annular groove at the slide upper limit position.

[0007]

According to the above construction, the liquid take-out nozzle is initially at the slide lower limit position for sealing the rubber stopper, and the inside of the vial and the liquid take-out port are shut off (see FIG. 1). When the cap member is pulled upward, the liquid take-out nozzle slides together with the cap member from the slide lower limit position to the slide upper limit position, and the inside of the vial and the liquid take-out port communicate with each other via the drug solution passage (see FIG. 2). When the cap member is pulled further upward, the cap member made of a flexible resin and the liquid take-out nozzle are deformed and the engagement state between them cannot be maintained, the cap member comes off the liquid take-out nozzle, and the inside of the vial. The chemical liquid stored in the liquid can be taken out from the liquid outlet. After using the vial cap for drip, if you cover the liquid ejecting nozzle with the cap member and press it strongly, the liquid ejecting nozzle will return to the slide lower limit position and the liquid ejecting nozzle and the cap member will engage, so restore the original state. can do.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a vertical sectional view showing a state before use of the drip vial cap of the present invention (the liquid take-out nozzle is at the slide lower limit position), and FIG. 2 is a cap member in the drip vial cap of FIG. Is pulled up and the liquid take-out nozzle is slid to the slide upper limit position, and FIG. 3 is a sectional view taken along the line AA shown in FIG. 1 of the vial cap for drip of the present invention.

As shown in FIG. 1, the drip vial cap of the present invention comprises a rubber stopper 1, a liquid take-out nozzle 2, a cap member 3 and a caulking member 4. A through hole 13 is formed on the shaft of the rubber stopper 1, and the liquid take-out nozzle 2
Is slidably inserted in the through hole 13. Then, the assembly of the rubber stopper 1 and the liquid take-out nozzle 2 is inserted into the mouth portion 51 of the vial 5 and fixed by the caulking member 4, and then the cap member 3 is attached. The liquid take-out nozzle 2 has an engaging means (engaging protrusion) with the cap member 3 at the upper end thereof.
When the cap member 3 is pulled upward, it slides from the slide lower limit position (closed state) to the slide upper limit position (communication state).

The rubber stopper 1 is usually a stopper made of a rubber-like elastic material such as butyl rubber or isoprene rubber, and has a top surface 11 and legs 12, and the top surface 11 is on the shaft.
A through hole 13 is formed to penetrate the leg 12. A liquid take-out nozzle 2 to be described later is slidably inserted into the through hole 13 so as to be slidable between a lower limit slide position and an upper limit slide position. When the liquid take-out nozzle 2 is at the lower slide limit position, the rubber stopper 1 is transparent. The hole 13 is thereby closed.

The top surface 11 is formed in a flange shape,
The caulking member 4, which will be described later, press-fits the mouth portion 51 of the vial 5. On the other hand, the leg 12 is inserted into the mouth portion 51 of the vial 5 and is in close contact with the inner wall of the mouth portion 51. An annular groove 14 is formed in an intermediate portion of the through hole 13 formed on the shaft of the rubber stopper 1, and the annular groove 14 is inserted into the through hole 13 at least when the liquid take-out nozzle 2 is at the upper limit slide position. The width is formed so that it can communicate with a communication hole 26, which will be described later, of the attached liquid extraction nozzle 2. That is, the liquid take-out nozzle 2
Is formed to be larger than the length of the liquid passage forming portion 222 described later.

The liquid take-out nozzle 2 is a nozzle-cum-plug body made of a flexible resin such as polypropylene, polyethylene, or polyester, and has a pipe-shaped nozzle portion having an inner cavity 25 opening to the liquid take-out port 24. 21 and a cylindrical plug body 22. The nozzle portion 21 has an engagement projection 23 that engages with a cap member 3 described later on the outer wall of the upper end, and a communication hole 26 that communicates with the annular groove 14 of the rubber plug 1 at the lower end. The number of the communication holes 26 is not limited, but about 1 to 4 may be formed. Further, the shape of the engaging projection 23 is not particularly limited, but an annular projection or a plurality of projections formed symmetrically with respect to the axis is adopted. Below the engagement protrusion 23, a gap for fitting an engagement protrusion 34 of the cap member 3 to be described later is left in the nozzle portion 21 to limit the downward slide when the liquid takeout nozzle 2 is moved downward. A flange 29 is formed. When the cap member 3 is attached, the flange 29 is pressed against the top surface 11 of the rubber stopper 1 so that the downward movement of the liquid take-out nozzle 2 is restricted (see FIG. 1). That is, when the drip vial cap is attached, the liquid take-out nozzle 2 automatically comes to the slide lower limit position (position where downward movement is restricted). The shape of the liquid outlet 24 is not limited to that shown in the figure, and it may be funnel-shaped or other shape having a narrower inner diameter.

The stopper 22 has an upper sealing portion 221 which closely adheres to and seals the leg 12 of the rubber stopper 1 when the liquid take-out nozzle 2 is at the slide lower limit position, and the liquid take-out nozzle 2 slides at the upper limit position. When the cap member 3 is at a position where its upward movement is restricted when pulled, a vertical groove 2 is formed between the cap member 3 and the leg 12 of the rubber stopper 1 which is in close contact with the cap member 3 to form a gap serving as a liquid passage. And a lower end of the liquid passage forming portion 222, the lower end of the liquid passage forming portion 222 collides with the lower end of the rubber stopper 1 when the liquid take-out nozzle 2 slides upward and reaches the slide upper limit position shown in FIG. In addition, an abutting projection 28 is provided which restricts the liquid take-out nozzle 2 from moving further upward. The length of the sealing portion 221 is substantially equal to the length of the leg portion 15 (sealing leg portion) of the through hole 13 of the rubber plug 1 which is sealed by the lower limit position of the slide of the liquid extraction nozzle 2 and the length of the vertical groove 27. (At least the entire portion of the liquid passage forming portion 222 excluding the abutment protrusion 28) is formed to have a length equal to or longer than that of the sealing leg portion 15. Usually, 1 to 4 vertical grooves 27 are formed, but the number thereof is not particularly limited. A communication passage 281 is also formed between the abutment projection 28 and the vertical groove 27. This communication passage 281 is formed by forming the vertical groove 27 in the entire liquid flow path forming portion 222 including the abutment projection 28. , Vertical groove 2 on the abutting projection 28
7 in which a hole communicating with 7 is formed, a radial groove or protrusion is provided at the lower end of the rubber stopper 1 so that the lower end of the rubber stopper 1 is not closed by the abutting protrusion 28, the lower end of the rubber stopper 1 Various shapes such as a shape in which radial grooves or protrusions are provided on the surface closely contacting with and can be adopted.

The combination of the rubber stopper 1 and the liquid take-out nozzle 2 seals the mouth portion 51 of the vial 5. However, when the liquid take-out nozzle 2 is moved upward, the liquid in the vial 5 is drip-dried. It becomes a drip mouth. That is, the top surface portion of the through hole 13 of the rubber plug 1 is always sealed by the nozzle portion 21 of the liquid take-out nozzle 2, while the sealing leg portion 15 of the through hole 13 causes the liquid take-out nozzle 2 to move to the lower limit position of the slide. In some cases, it is sealed by the plug portion 22, and when the liquid take-out nozzle 2 is at the slide upper limit position, a liquid passage (the annular groove 14 of the rubber plug 1 and the liquid take-out nozzle 2 is provided between the rubber plug 1 and the liquid take-out nozzle 2). The vertical groove 27, the communication hole 26, and the communication passage 281 are formed. Therefore, when the liquid takeout nozzle 2 is at the slide lower limit position, the mouth portion 51 of the vial 5 has the rubber stopper 1 and the liquid takeout nozzle 2
The liquid extraction nozzle 2 is sealed by a combination of
Is located at the upper limit position of the slide, the liquid outlet 24 communicates with the inside of the vial 5.

After the combination of the rubber stopper 1 and the liquid take-out nozzle 2 is inserted into the mouth portion 51 of the vial 5, it is securely fixed to the mouth portion 51 by the caulking member 4 made of aluminum or the like. In this way, the sealing member (combination of the rubber stopper 1, the liquid take-out nozzle 2 and the caulking member 4) attached to the mouth of the vial 5, especially the liquid take-out port 24 of the liquid take-out nozzle, is capped with this. Protected from pollution by 3.

The cap member 3 is made of the same flexible resin as that of the liquid take-out nozzle 2, and has a top surface 31 and a skirt 3.
It consists of two. The top surface 31 has a function of protecting the plug 1 and the liquid take-out nozzle 2 and also having a function of sliding the liquid take-out nozzle 2 from the slide lower limit position to the slide upper limit position. Therefore, a convex portion 33 is provided on the outer surface of the top surface 31, and an engaging means (engaging protrusion) 34 that engages with the engaging protrusion 23 of the liquid take-out nozzle 2 is provided on the inner wall of the convex portion 33.
Is provided. With this configuration, when the cap member 3 is pulled upward, the liquid take-out nozzle 2 can slide to the slide upper limit position, and the abutting protrusion 28 abuts the lower end of the rubber stopper 1 to take out the liquid. While the upward movement of the nozzle 2 is blocked, the liquid take-out nozzle 2
Since the material for forming the cap member 3 is a flexible resin, pulling the cap member 3 upward deforms the liquid take-out nozzle 2 and / or the cap member 3 to break the engagement between the two. The cap member 3 can be removed from the combination of the rubber plug 1, the liquid take-out nozzle 2 and the caulking member 4. A plurality of vertical ribs 35 that engage with the caulking member 4 may be provided on the inner wall of the skirt 32.
