Description

[Detailed Description of the Invention] The present invention relates to an ampoule-shaped container for use in horticulture with solutions of plant activators, fertilizers, and other drugs necessary for plant growth. In recent years, gardening has become more popular, and plant activators,
There is a need for a container that can always supply a constant amount of fertilizer and other chemicals necessary for plant growth into the soil at the base of plants. However, no container has been provided that meets this requirement.
The object of the present invention is to provide a container that can always supply a constant amount of chemical solution into soil.

In order to meet the above-mentioned requirements, the present invention has a container body 1 having a liquid supply port and a ventilation port, and a liquid supply port plug 2 and a ventilation port plug 3 into which a stem 4 is press-fitted. This is an ampoule-shaped container with one or more narrow grooves 6 from the middle.When the drug solution is contained, the container body 1 is sealed with the part of the stem 4 that does not have the narrow grooves, and when in use, the narrow grooves 6, liquid supply port, and ventilation are sealed. A capillary tube is formed between the capillary tube and the inner peripheral surface of the mouth, with one end opening inside the container body 1 and the other end opening to the outside world, so that the gas phase inside the container can be ventilated with the outside world,
To provide an ampoule type container in which a medicinal liquid always flows out in a constant amount through a capillary tube formed by a liquid supply port plug 2.

The ampoule type container according to the present invention has a capillary tube outside the inlet for supplying the chemical solution to the soil, which allows the gas phase inside the container to constantly communicate with the outside world. For this reason,
The gas phase inside the ampoule type container is maintained in almost the same state as the outside air under any conditions during use, and the outflow of the chemical solution is determined by the size and number of capillaries formed by the narrow groove of the liquid supply port plug 2 and the liquid supply port. By selecting the size and number of narrow grooves according to the viscosity of the chemical solution, desired flow rate, etc., it is possible to quantitatively supply the chemical solution into the soil over a relatively long period of time.

The present invention will be specifically explained below with reference to Examples.

FIG. 1 is a partial sectional view of an ampoule-shaped container showing an example of the present invention. A liquid supply port plug 2 and a ventilation port plug 3 are attached to a liquid supply port and a ventilation port provided in a hollow resin container body 1, respectively. As shown in FIG. 2, these plugs are composed of a head 5 and a stem 4, and a narrow groove 6 extends from the middle of the cylindrical stem 4 to the outer edge of the head 5 as a continuous groove. As shown in FIG. 1, the plug 3 is attached to the container before it is filled with a drug solution, and the portion of the stem 4 where the groove 6 is not cut seals the container. In addition, the plug 3 is designed to hold the ampoule-shaped container upright when filling the container with the drug solution.
The head 5 is positioned so as not to protrude from the lower end 7 of the container body. The liquid supply port plug 2 seals the ampoule container with the groove-free portion of the stem 4 after filling the container with the drug solution. When using an ampoule-shaped container filled with a chemical solution, as shown in Figure 3, push the heads of plugs 2 and 3 until they touch the container body, and connect the grooves 6 of plugs 2 and 3 to the liquid supply port and ventilation of the container body. A capillary is formed between the capillary and the inner peripheral surface of the mouth, one end of which is opened inside the container and the other end is opened to the outside world, and the liquid supply port plug 2 is inserted into the soil at the base of the plant. Since the capillary tube formed between the plug 3 and the inner peripheral surface of the vent port communicates between the outside world and the inside of the container, the gas phase generated inside the ampoule-shaped container is under almost the same conditions as the outside world, and the chemical solution is always kept constant. , and continues to flow out in a constant amount through the capillary tube formed by the plug 2.

This container does not require any special effort to use.
You can predict when the chemical solution will run out, and the soil, gas, moisture, and other contaminants in the soil will not flow back into the container during use, so the chemical solution will not change during use, and the soil The amount of outflow does not fluctuate due to the nature of These facts indicate that it can also be used as an ampoule for water culture, which is currently popular.
