[Prior art]
Conventionally, a drug solution container of a drug solution sprayer is provided integrally with a drug solution sprayer main body, and each time a drug solution runs out, a drug and water are poured directly from an inlet, diluted, blended, and used repeatedly. Was. In the case of such a liquid medicine container, when the medicine and water are poured from the injection port, the medicine is easily spilled, and the surrounding environment is easily polluted. In addition, the spilled medicine adheres to the human body and clothes, and the safety is easily impaired. In addition, in the dilution preparation by directly pouring the medicine and water from the injection port, the dilution amount is apt to be mistaken, which may cause unexpected damage to useful plants and sometimes fail to obtain the expected effects. Furthermore, when cleaning the chemical sprayer to use different types of chemicals, it is difficult to remove and store the previously used chemical even if it remains. Unnecessary spraying of the chemical solution was caused by spraying more than necessary or washing out the remaining chemical solution in an attempt to use up.
[0003]
Under such circumstances, a chemical sprayer using a cartridge-type chemical solution container as shown in FIG. 6 has recently been developed.

[Problems to be solved by the invention]
By using the cartridge type chemical solution container as shown in FIG. 6, it is possible to solve the above-described problems in the case of using the chemical solution container integrated with the sprayer.
[0007]
However, in the conventional cartridge-type chemical solution container, all of the chemical solution in the container cannot be used up, and there is a considerable amount of residual chemical solution. In addition, there is a fear that constituent members such as an outer cylinder and an inner cylinder of the spout may swell with a chemical solution and loosely adhere, and there is a concern that the chemical solution may leak during use or disposal of the container.
[0008]
An object of the present invention is to provide a cartridge-type chemical solution container that can solve the problems of the conventional cartridge-type chemical solution container.
[0009]

[0011]
Embodiment and operation
An embodiment of the present invention will be described with reference to FIGS.
[0012]
FIG. 1 shows components of a spout 105 which is attached to a cartridge type chemical solution container and has an outlet for a chemical solution. In FIG. 1, 1 is an outer cylinder, 2 is a packing, 3 is an inner cylinder, and 4 is a cap. .
[0013]
The outer cylinder 1 has a concave portion 15 on the inner peripheral surface and has a cylindrical shape with both ends opened. An upper flange 11 is provided at an intermediate portion thereof. A fitting projection 12 is formed on the peripheral surface. An outer cylinder locking projection 13 is provided on the outer periphery of the other end (lower end) of the outer cylinder 1, and a lower flange 14 is provided below the upper flange 11 with a rib interposed therebetween. I have.
[0014]
The packing 2 is mounted in the outer cylinder 1, and has a fitting recess 21 and a groove 22 for forming an outflow port.
[0015]
The inner cylinder 3 has a cylindrical shape with one end (upper end) closed and the other end (lower end) opened. A tube engaging portion 32 and a convex portion 33 protruding outward from the lower peripheral edge are provided respectively.
[0016]
FIG. 2 shows a part of a cross section of the chemical liquid container having the spout 105 of FIG. 1 when not in use. FIG. 2A is a cross sectional view taken along line AA of FIG. FIG. 3 is a cross-sectional view taken along line BB of FIG.
[0017]
As shown in FIG. 2, the chemical solution container main body 104 and the outer cylinder 1 are integrated. The packing 2 is fixedly mounted in the outer cylinder 1 such that the fitting concave portion 21 is fitted into the fitting convex portion 12 of the outer cylinder 1. The inner cylinder 3 is inscribed in the outer cylinder 1 and the packing 2 so as to be in close contact with the outer cylinder 1 and the packing 2 so as to be rotatable around the central axis. The fall-off is prevented by being fitted. Further, the groove 22 of the packing 2 and the perforation 31 of the inner cylinder 3 are respectively located at positions corresponding to the circumferential direction, and the positions of the groove 22 and the perforation 31 are shifted from each other when not used as shown in FIG. The outlet is closed.
[0018]
The packing 2 is a member constituting the outflow port and also functions as a chemical liquid leakage preventing member, and an elastic material having 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 are particularly preferably used.
[0019]
As described above, since the packing 2 acts as a chemical liquid leakage preventing member, there is no risk of chemical liquid leakage when the outflow port is closed, but it is possible to prevent foreign matter from entering the inner cylinder 3 before use and to prevent chemical liquid leakage. In order to achieve this, it is preferable to attach the cap 4 as shown in FIG.
[0020]
The cap 4 can be easily attached to the outer cylinder 1 by turning. The cap 4 is attached by engaging a cap locking projection 41 provided inside the cap 4 with the outer cylinder locking projection 13 of the outer cylinder 1, whereby the lower end surface of the outer cylinder 1 is The packing 42 is abutted and sealed.
[0021]
The upper surface of the groove 22 of the packing 2 is located at the deepest region of the chemical in the chemical container main body 104. For this reason, since the position of the groove 22 of the packing 2 and the position of the perforation 31 of the inner cylinder 3 coincide with each other and the outlet is opened, the liquid medicine in the liquid medicine container main body 104 can be completely used up without being left. Particularly, as in the present embodiment, the space inside the chemical solution container main body 104 is narrowed while being inclined toward the groove 22 of the packing 2, so that the chemical solution remains on the bottom surface of the chemical solution container main body 104 extremely. It can be prevented efficiently.
[0022]
The outlet is opened by operating the handle lever 106 with the spout 105 attached to the socket 102 of the chemical sprayer main body as shown in FIG. It can be done by doing. Specifically, when the spout 105 is mounted, a rod (not shown) provided on the socket 102 is inserted into the inner cylinder 3 of the spout 105, and the engaging portion 32 (see FIG. See). The rod is rotated by the operation of the handle lever 106, and the inner cylinder 3 is rotated accordingly.
[0023]
The chemical solution container body 104 may be a blow-molded synthetic resin tank-shaped container, a PET bottle-shaped thin stretch blow-molded container, or a synthetic resin sheet bag formed of paper (eg, cardboard) box. It is also possible to use a so-called BIB (back-in-box) housed in a box. It is also preferable to use a biodegradable synthetic resin to facilitate waste disposal.
[0024]
When the BIB is used as the chemical solution container, the bag made of the synthetic resin sheet is deflated and the pressure in the bag is adjusted with the consumption of the chemical solution. There is an advantage that an intake port with a check valve that allows air to enter the air becomes unnecessary.
[0025]
FIG. 3 shows an example in which a bag made of the above-mentioned synthetic resin sheet is used for the chemical liquid container body. This is obtained by sealing a synthetic resin sheet into a tubular shape and further bending it to form an accordion (see FIG. 3 (a)), and sealing the upper edge portion of the outer cylinder 1 of the spout shown in FIG. (See FIG. 3B). The bag is provided with a plurality of seals for defining an internal space. The seal portion 50a, which is provided so as to be inclined toward the outlet of the spout 105 below the bag, is for efficiently discharging the chemical solution so that the chemical solution does not remain at the bottom of the bag. In addition, the seal portion 50b provided at an angle above the bag is for preventing the chemical solution from remaining on the upper portion of the bag, particularly at the corners.
[0026]
When the chemical solution container body is a BIB using a bag made of a synthetic resin sheet as described above, the spout 105 is difficult to move in order to facilitate attachment to the socket 102 (see FIG. 6) of the chemical solution sprayer body. It is preferable to have a structure protruding from the box.
[0027]
In the case of BIB, since it is difficult to check the remaining amount of the chemical solution, it is preferable that the inner bag is made of, for example, a transparent synthetic resin and that the outer box has a viewing window 51 as shown in FIG.
[0028]
In the example shown in FIG. 3, the seal portion 50a is formed to incline the space in the bag toward the outflow port side so as to become narrower. However, the inclined member 52 as shown in FIG. Can also be carried out by mounting it in an outer box as shown in FIG. Thereby, the inner bag in which the seal portion 50a is formed is in the original folded state, and the residual liquid can be reduced.
[0029]
【The invention's effect】
As described above, the cartridge-type drug solution container of the present invention has an outlet formed at a portion in contact with the deepest portion of the injected drug solution, and thus can be used up without leaving the drug solution in the drug solution container. Particularly, in the case where the inner space is narrowed while being inclined toward the outlet, the residual of the chemical solution can be prevented very efficiently. In addition, since the inner cylinder is fitted into the outer cylinder via packing, there is no need to worry about leakage of residual chemicals when using or disposing of the container, improving the safety of handling and preventing environmental pollution. There is an effect that can be done.
