A fitting convex portion 12 is formed on the inner peripheral surface of the portion. An outer cylinder locking projection 13 is provided on the outer peripheral portion of the other end (lower end) of the outer cylinder 1, and the upper flange 11 is further provided.
A lower flange 14 is provided on the lower side of the with a rib interposed therebetween.

The packing 2 is mounted in the outer cylinder 1, and is provided with a fitting recess 21 and a groove 22 for forming an outflow port.

The inner cylinder 3 has a cylindrical shape with one end (upper end) closed and the other end (lower end) open. The inner cylinder 3 has a perforation 31 for forming an outflow port and a central axis direction on the inner peripheral side. An extended inner cylinder engaging portion 32 and a convex portion 33 protruding outward from the lower end peripheral edge are respectively provided.

FIG. 2 shows a part of the cross section of the drug solution container having the spout 105 of FIG. 1 when not in use.
2A is a sectional view taken along the line AA of FIG. 1, and FIG.
It is sectional drawing in the BB line of (a).

As shown in FIG. 2, the liquid medicine container body 10 is shown.
4 and the outer cylinder 1 are integrated. The packing 2 is the outer cylinder 1
The fitting concave portion 21 is fixedly mounted in the outer cylinder 1 so as to be fitted into the fitting convex portion 12. The inner cylinder 3 is inscribed in the outer cylinder 1 and the packing 2, and is inserted in a close contact state so as to be rotatable about the central axis, and the convex portion 33 protruding outward at the lower end peripheral edge is formed in the concave portion 15 on the inner periphery of the outer cylinder 1. It is prevented from falling by being fitted. Further, the groove 22 of the packing 2 and the perforation 31 of the inner cylinder 3 are located at positions corresponding to each other in the circumferential direction, and the positions of the groove 22 and the perforation 31 are displaced from each other when not in use as shown in FIG. The outlet is closed by.

The packing 2 is a member that constitutes the outlet and also acts as a chemical liquid leakage prevention member.
An elastic material having a high chemical resistance is preferably used. For example, silicone rubber and fluorine-based rubber have little swelling and can maintain the rotational resistance of the inner cylinder 3 for a long period of time, and can be used particularly preferably.

As described above, since the packing 2 acts as a chemical liquid leakage prevention member, there is no fear of chemical liquid leakage when the outlet is closed, but foreign matter may enter the inner cylinder 3 before use and may be reliably discharged. In order to prevent the chemical liquid from leaking, it is preferable to attach the cap 4 as shown in FIG.

The cap 4 can be easily attached to the outer cylinder 1 by turning it. The cap 4 is attached by engaging the outer cylinder locking projection 13 of the outer cylinder 1 with the cap locking projection 41 provided inside the cap 4, whereby the lower end surface of the outer cylinder 1 is attached. The packing 42 is abutted and sealed.

The upper surface of the groove 22 of the packing 2 is located at the deepest area of the chemical liquid in the chemical liquid container body 104. Therefore, the groove 22 of the packing 2 and the perforation 31 of the inner cylinder 3
By aligning the positions of and the opening of the outflow port, the liquid medicine in the liquid medicine container body 104 can be used up almost without being left. Particularly, as in this embodiment, the chemical liquid container body 104
By narrowing the inner space while inclining toward the groove 22 side of the packing 2, it is possible to very effectively prevent the chemical solution from remaining on the bottom surface of the chemical solution container body 104.

The outlet is opened by operating the handle lever 106 while the spout 105 is attached to the socket 102 of the main body of the chemical spraying machine as shown in FIG. It can be done by rotating inside. Specifically, when the spout 105 is attached, a rod (not shown) provided in the socket 102
Is inserted into the inner cylinder 3 of the spout 105, and the rod and the engaging portion 32 (see FIG. 1) of the inner cylinder 3 are engaged with each other. And
The rod is rotated by the operation of the handle lever 106, and the inner cylinder 3 is rotated accordingly.

As the chemical liquid container body 104, in addition to a blow-molded synthetic resin tank-shaped container, a PET bottle-shaped thin stretch blow-molded container and a synthetic resin sheet bag made of paper (for example, cardboard). So-called B housed in a box such as
It is also possible to use an IB (back in box). It is also preferable to use a biodegradable synthetic resin to facilitate waste disposal.

When BIB is used as the chemical solution container, the bag made of a synthetic resin sheet is deflated as the chemical solution is consumed and the pressure inside the bag is adjusted, so that the chemical solution is consumed as in the case of using a hard container. At the same time, there is an advantage that an intake port with a check valve that allows air to enter the container is not required.

FIG. 3 shows an example in which the bag made of the above synthetic resin sheet is used for the main body of the chemical liquid container. This is a product in which a synthetic resin sheet is sealed in a tubular shape and further bent to form an accordion shape (see FIG. 3 (a)), which is sealed to the upper edge portion of the outer cylinder 1 of the spout shown in FIG. (Fig. 3
(B)). The bag is provided with a plurality of seals for defining the internal space. The seal portion 50a provided so as to incline toward the outlet side of the spout 105 below the bag is for efficiently discharging the chemical liquid so that the chemical liquid does not remain at the bottom of the bag. Further, the seal portion 50b inclined above the bag is provided to prevent the chemical solution from remaining on the upper portion of the bag, especially at the corners.

When the chemical solution container body is a BIB using a bag made of a synthetic resin sheet as described above, the spout 105 moves in order to easily mount the chemical solution sprayer body into the socket 102 (see FIG. 6). It is preferable to have a structure protruding from the box in a difficult state.

Further, in the case of BIB, since it is difficult to confirm the remaining amount of the chemical solution, the inner bag is made of, for example, a transparent synthetic resin, and the outer box has a peep window 51 as shown in FIG. preferable.

In the example shown in FIG. 3, the seal portion 50a is formed in order to make the space in the bag inclined toward the outlet side and narrow, but as shown in FIG. 5 (a). It can also be performed by mounting the tilt member 52 in the outer box as shown in FIG. Thereby, the seal portion 50
The inner bag in which a is formed is in the original folded state, and the residual liquid can be reduced.

[0029]

As described above, in the cartridge type chemical liquid container of the present invention, the outflow port is formed at the portion in contact with the deepest portion of the injected chemical liquid, so that the chemical liquid in the chemical liquid container is almost left. It can be used up without any problem, and in particular, in the case where the internal space is narrowed while inclining toward the outlet side, it is possible to prevent the chemical liquid from remaining extremely efficiently. In addition, since the inner cylinder is fitted into the outer cylinder via the packing, the close contact is good, and there is no concern about leakage of residual chemical liquid when using or discarding the container, improving the handling safety and
It has the effect of preventing environmental pollution.
