Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of an ampoule for supplying agricultural chemicals, fertilizers, etc. used for horticulture.

[Conventional technology]

Conventionally, there are many ampoules for supplying agricultural chemicals, fertilizers, etc. used exclusively for horticulture on the market, but a typical example is one with the structure shown in Figure 4 ( There is a conventional technology (hereinafter referred to as prior art 1). In this supply ampoule A', a cap 13 having a conduit formed inside so as to communicate with the thin tube section is fitted at the tip of a thin tube section 12 that communicates with the inside of the ampoule body 11 filled with agricultural chemicals, fertilizers, etc. When in use, a hole is cut at the tip of the cap 13 at point D, and the conduit of the cap (as a result, the inside of the ampoule) is communicated with the outside, as shown in FIG. By turning the ampoule A' upside down and holding it upright by sticking the cap part into a predetermined soil surface B where the plant C is planted, the liquid pesticide, liquid fertilizer, etc. filled inside the ampoule body can be removed. The idea is to energize plants by letting them gradually flow into the soil like a drip over a long period of time.

Also, although not shown, as prior art 2, there is a type of agricultural chemical fertilizer in which a fragile part is provided at the tip of a cap made of rubber or synthetic resin, and this part is threaded to make a hole that allows communication between the inside of the ampoule and the outside. There is also a supply ampoule, but the method of use is exactly the same as in Prior Art 1 above.

[The problem that the idea aims to solve]

However, according to the supply ampoule according to Prior Art 1, the size of the cut end (hole) changes depending on how the tip of the cap is cut, and the agricultural chemicals and fertilizers inside the ampoule may come out too quickly or too slowly. Therefore, it becomes impossible to adjust the outflow amount, and the desired effect of this type of ampoule cannot be expected.

In addition, according to the supply ampoule according to Prior Art 2, when the tip of the cap is screwed off, force is applied to the ampoule held in the other hand due to the twisting force, and the agricultural chemicals, fertilizers, etc. inside the ampoule are The parts tend to fly out from the hole provided at the tip of the cap, which not only results in loss of parts, but also tends to stain clothes and hands.

Furthermore, a common feature of these conventional techniques is that a hole is formed at the tip of the cap to allow pesticides, fertilizers, etc. to flow out, so that the hole is likely to become clogged with soil or sand particles during use. Therefore, drip-like outflow of agricultural chemicals, fertilizers, etc. cannot be expected at all, and the original purpose of the supply ampoule cannot be achieved.

The present invention has been developed in view of the above-mentioned problems with the conventional technology, and its purpose is to form holes extremely easily, without using scissors, etc., to allow agricultural chemicals, fertilizers, etc. to flow out. There is no risk of the pesticide fertilizer inside the ampoule scattering when the hole is formed, and the hole is less likely to be clogged with sand or soil during use, allowing the pesticide fertilizer etc. filled in the ampoule body to gradually and continuously flow out. The aim is to provide ampoules for supplying agricultural chemicals, fertilizers, etc.

[Means to solve the problem]

In order to achieve the above object, the gist of the present invention is to provide an ampoule for supplying agricultural chemical fertilizers, etc., in which a cap is fitted to the tip of a thin tube portion of the ampoule filled with liquid agricultural chemical fertilizers, etc. When the cap is in the fitted state, the hole in the thin tube part is closed by the closing part inside the cap, and when the cap is loosened, the hole in the thin tube part and the stopper inside the cap are closed. An ampoule for supplying agricultural chemicals, fertilizers, etc., characterized in that the cap is spaced apart, the tip of the groove is exposed to the outside of the cap, and the inside of the cap and the outside communicate with each other through the groove. be.

〔Example〕

Next, embodiments of the present invention will be described based on the accompanying drawings.

Figure 1 is a front view of the ampoule for supplying agricultural chemicals, fertilizers, etc. according to the present invention, Figure 2 is an enlarged sectional view of the main parts of the supply ampoule of Figure 1 before use, and Figure 3 is the supply of agricultural chemicals shown in Figure 1. FIG. 2 is an enlarged cross-sectional view of the main part of the ampoule in use.

In FIG. 1, A is an ampoule for supplying agricultural chemicals, fertilizers, etc. according to the present invention, 1 is an ampoule body made of polyethylene, etc., and 2 is a thin tube part formed integrally with this ampoule body. ,
This ampoule is filled with a predetermined amount of liquid pesticide or fertilizer. A cap 3 is fitted onto the tip of the thin tube portion.

The specific relationship between the cap and the capillary portion is as shown in FIG. The two are screwed together. Furthermore, at least one vertically elongated groove 4 is carved in the male thread 5 portion of the thin tube portion 2, and this groove 4 is formed when the thin tube portion 2 is completely screwed into the cap 3. is completely hidden by the cap 3, and the hole 8 in the thin tube portion 2 is closed by a closure 7 inside the cap 3. Further, as shown in FIG. 3, when the threaded connection between the cap 3 and the thin tube portion 2 is loosened during use, the hole 8 in the thin tube portion 2 and the closure portion 7 inside the cap 3 are separated and the groove 4 is opened. The tip is exposed to the outside of cap 3,
The cap 3 is configured so that the inside and outside of the cap 3 can communicate with each other via the groove 4.

Note that it is sufficient that at least one groove 4 is provided, and there is no particular problem even if the groove 4 is formed obliquely or spirally, rather than being vertically long.

[Effect]

Since the present invention is constructed in this manner, before use, the hole 8 of the thin tube portion 2 is closed by the closure part 7 inside the cap 3, as shown in FIG. When the screwing state between the cap 3 and the thin tube part 2 is loosened as shown in FIG. Exposed to the outside from the base of cap 3. In this state, the inside 9 of the cap is filled with fillers such as agricultural chemicals and fertilizers, which enter the gap 10 formed between the inner wall of the cap 3 and the outer circumferential wall of the thin tube portion 2, and then undergo capillary action. As a result, the filling material enters the groove 4 and rises, and as a result, the filling material oozes out to the outside of the ampoule. If the flow of this filling is shown in Figure 3, a → b
become that way. Then, when this supply ampoule A is turned upside down as shown in Fig. 5 and the cap 3 part is stuck into the soil surface B and held, the filler such as agricultural chemicals and fertilizers inside the ampoule will pass through the groove 4 to the outside. It will leach into the soil and permeate into the soil.

[Effect of idea]

According to the ampoule for supplying agricultural chemicals, fertilizers, etc. according to the present invention configured as described above, the following effects are achieved.

(1) Depending on the tightening or loosening of the screwed state of the cap, the state of exposure of the groove to the outside of the cap for draining agricultural chemicals, fertilizers, etc. filled inside the ampoule can be adjusted. Therefore, there is an advantage that the amount of agricultural chemicals, fertilizers, etc. flowing out from the inside of the ampoule can be adjusted.

(2) The position of the hole, that is, the groove, for allowing the agricultural chemical fertilizer, etc. Since it is provided around the thin tube portion exposed from the end surface of the cap on the proximal end side, when the cap is thrust into the soil surface, soil and sand particles from the soil will clog the exposed portion of the groove. There is little risk, and as a result, the agricultural chemicals and fertilizers inside the ampoule gradually flow out over a long period of time without clogging the grooves, allowing a stable supply of agricultural chemicals and fertilizers to the soil.
