Description

[Detailed description of the invention] This invention relates to a syringe-type filling container for liquid that also serves as a syringe.

Conventionally, in this type of filled container, for example, a syringe-type container for oral administration of drug solutions to livestock, etc., the container itself has a dosing device so that the drug solution in the container can be adjusted to the weight of the livestock and administered as is by increasing or decreasing it as appropriate. It seems that it also serves as.

By the way, this type of syringe has a scale displayed on the dispensing rod to read the amount of medicinal solution dispensed, and the required amount is dispensed using the scale, but since it is structurally similar to a syringe, Since the rod dispenses the medicinal liquid even with the slightest pressure, there are many cases where the amount of dispensing is incorrect or the medicinal liquid leaks out due to carelessness, so great care must be taken when handling the rod.

This invention was proposed in view of these conventional drawbacks, and it is possible to dispense and administer a predetermined amount of a drug solution without making a mistake, and also to prevent inadvertent leakage of the drug solution.

Hereinafter, this invention will be explained in detail based on the embodiments shown in the drawings.

FIG. 1 shows an example of a filling container that also serves as a syringe.

That is, an injection nozzle 2 is integrally protruded from the tip of an outer cylinder 1 made of plastic or the like, and this injection nozzle 2 is closed with a detachable cap 3.

An inner cylinder 4 is inserted into and out of the outer cylinder 1, and
It is made of the same material as the outer cylinder 1.

The tip of the inner cylinder 4 is integrally formed with a flange 5 having a reduced diameter part 5a, and a sealing member 6 made of elastic rubber is wrapped in this flange 5. Supported by 5a.

This sealing member 6 can slide on the inner wall of the outer cylinder 1 in a watertight manner, and has a small through hole 7 opened in its center.

Further, an air discharge valve 8, which is a member equivalent to the seal member 6, is installed inside the tip of the inner cylinder 4, and the tip extends into the flange 5 and is supported.

A passage 9 communicating with the through hole 7 provided in the sealing member 6 is provided in the center of the air discharge valve 8, and a spherical enlarged diameter portion 10 is provided in the middle of the passage 9, and the rear end thereof is internally disposed. Tube 4 11! A tapered wall 11 is formed at I.

"Thereby, the outer cylinder 1 and the inner cylinder 4 are communicated through the through hole 7 of the seal member 6 and the passage 9 of the air discharge valve 8.

Further, at the rear end of the inner cylinder 4, a flange plate 4a that comes into contact with the rear end of the outer cylinder 1 is provided.
is provided.

An injection rod 12 having a push seat 16 formed at the rear end is inserted into the inner cylinder 4 so as to be freely removable and removable.
is a frame 13 with a cross-shaped cross section provided around a central shaft rod.
can come into sliding contact with the inner wall of the inner cylinder 4.

Furthermore, the enlarged diameter portion 1 of the air discharge valve 8 is located at the tip of the injection rod 12.
A spherical portion 15 is provided which fits closely with the spherical portion 15 and the frame 13 behind the spherical portion 15 is cut to mate with the two tapered portions 11.

In the filling container constructed as described above, after filling the outer cylinder 1 with a liquid such as a medicinal solution, the inner cylinder 4 is inserted into the outer cylinder 1, and then the injection rod 12 is inserted into the inner cylinder 4. When inserted, the air sealed in the outer cylinder 1 together with the liquid inside is permanently discharged, and the inner cylinder 4 is attached.

Now, in the above-mentioned filling container, as shown in FIG. A guide groove 14 is formed which continues in a stepped manner along the entire length of the outer circumferential surface in the longitudinal direction, and a dish-shaped recess 15 is formed near the lower end of each step of the guide groove 14. A first scale part 16 formed by a hollow, and a linear guide groove 17 having the same length as the stepped guide groove 14 along the longitudinal direction of the outer peripheral surface of the outer cylinder 1.
A plurality of relatively shallow dish-shaped recesses 1 are formed in the guide groove 17 at positions corresponding to the respective dish-shaped recesses 15 in the circumferential direction.
A second scale portion 19 is formed in the shape of 8.

Incidentally, in order to smoothly move the second scale stopper means from the first scale if necessary, a second scale part corresponding to each plate-shaped recess 15 of the first scale part 16 is provided. Each of the 19 dish-shaped recesses 18 may be connected with a guide groove, or both the guide grooves 14 and 17 may be connected with a thin guide groove.

The first and second scale portions 16.19 each have a dish-shaped recess 1.
A scale number 20 is displayed near positions 5 and 18.

On the other hand, the stopper means provided on the flange plate 4a
A stop lever 21 is extended along the outer cylinder 1 from a,
The distal end thereof is bent so as to be able to engage and disengage from either of the dish-shaped recesses 15, 18 to form an engagement portion having a bowl-shaped engagement surface, thereby forming a stopper means.

The stop lever 21 has its tip engaged with the dish-shaped recess 15 or 18 at the rearmost position when the inner cylinder 4 is retracted the most with respect to the outer cylinder 1, and when the stop lever 21 is pushed forward the most. That is, it is shaped so that it is engaged with the dish-shaped recess 15 or 18 at the forefront when the liquid is completely poured out.

Since the present invention has the above-described structure, when the liquid is tightly filled in the outer cylinder 1, the first scale part 15, for example,
When the stopper lever 21 is engaged with the dish-shaped recess 15 marked with the number 10 on the scale number 20, the number 1 is placed inside the outer cylinder 1.
This means that the liquid amount corresponding to 0 is filled.

In this state, even if the flange plate 4a of the inner cylinder 4 is touched inadvertently, the tip of the stopper lever 21 is engaged with the dish-shaped recess 15, so that the inner cylinder 4 is prevented from being pushed forward, and therefore the liquid is Leakage is prevented.

Next, when dispensing liquid, first remove the cap 3 of the injection nozzle 2 and insert the tip of the stopper lever 21 into the shape of a plate with the number 10. It is removed from the recess 15 and the stepped guide groove 16, and the stopper lever 21 is rotated along the outer cylinder 1 to engage with the plate-shaped recess 18 in the linear guide groove 17 marked with the number 10 on the second scale part 19. .

Then, press the flange plate 4a of the inner cylinder 4 a little forcefully to release the inner cylinder 4.
When pushed forward, the tip of the stopper lever 21 climbs over the dish-shaped recess 18 with which it is engaged and enters the adjacent dish-shaped recess 1.
8.

Then, when the inner cylinder 4 is pushed forward by pressing the flange plate 4a, the linear guide groove 17 and its dish-shaped recess 18 slide the stop lever 21 while producing a moderation function. It will be moved.

Therefore, if the pressure on the flange plate 4a is stopped as appropriate, the stopper lever 21 will engage with the dish-shaped recess 18 at the desired position.

This allows the desired amount of liquid to be dispensed.

After dispensing the liquid, the stopper lever 21 should be kept in rotational engagement with the dish-shaped recess 15 of the first scale part 16 corresponding to this dish-shaped recess 16, except when dispensing is to be performed continuously. The jamming prevents the inner cylinder 4 from being pushed forward.

In addition, when dispensing the required amount using one scale according to the present invention, it is of course possible to use the second scale to dispense as described above, but it is possible to dispense using the second scale as described above. By rotating the stop lever 21 that is in the position and positioning it in the step-shaped guide groove 14 adjacent to the stop lever 21, the inner cylinder 4 is pushed forward and the stop lever 21 is engaged with the dish-shaped recess 15 of that step. , a predetermined amount of liquid is dispensed.

Therefore, when repeatedly dispensing a predetermined amount from one container, by repeating the above operations in sequence, dispensing can be efficiently performed without accidentally dispensing more than the predetermined amount.

Note that the filling container is not limited to the embodiments described above, and can be widely used in other general syringes consisting of an outer cylinder and an injection rod.

As described above, according to this invention, inadvertent leakage of liquid can be prevented at the first scale part, a predetermined amount can be efficiently and repeatedly dispensed, and the desired amount can be dispensed at the second scale part. It is possible to provide a filling container which also serves as a syringe, which allows liquid to be poured out without error and which prevents liquid from accidentally leaking out due to careless handling.

Therefore, it is extremely effective as a filling container that also serves as a syringe for medicinal solutions to be administered to livestock, etc.
