Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an inner stopper for a container used, for example, for spraying agricultural chemicals, and a container fitted with the inner stopper to be filled with a chemical solution for spraying. It concerns liquid medicine.

(Prior Art) Pesticides are often used to exterminate pests in fields, but they are not limited to fields, but are also sprayed on home gardens and the like.

E4 medicines are generally sold in concentrated liquid form or in the form of Eiwa-ku, so that they can be diluted with water or dissolved in water. Immediately before spraying, they are mixed with water in an appropriate container to a predetermined concentration. It is diluted to

(Problem to be solved by the invention) Pesticides are used in large quantities when sprayed on fields, and the users are also skilled professionals, so diluting them is easy and there is no need to make mistakes in the dilution ratio. However, when used in home gardens, etc., it is often difficult to dilute properly, and during the dilution process, it may spill or adhere to clothing. Furthermore, because the concentrate is concentrated, I ended up purchasing more than I needed to spray on a small vegetable garden. This was due to the fact that pesticides are only sold in concentrated form. Pesticides could be sold in a pre-diluted state, but there were no containers suitable for easy spraying after purchase.

The present invention has been made in view of this point, and provides an inner stopper that can be sprayed as soon as the outer pillar is removed, and a drug solution in a container filled with a container using this inner stopper. The purpose is to

(Means for Solving the Problems) As a means for solving the above problems, the present invention provides an inner stopper l for a container, which is an inner stopper l attached to the mouth of an original container 6 to be filled with liquid. Then, a large number of small holes 5 are bored in the meat part 4, and a space is formed in a position where the base end faces the bottom of the container 6 or by turning the container upside down at a position avoiding the small holes 5 in the meat part 4. (see Figure 6) and, in the case of a container with a hollow handle 9 formed integrally with the container body, the tip of the tube 8 with a length that reaches the handle 9 (see Figure 7). It has a configuration with a .

As a specific embodiment, the tip of the tube 8 penetrates the inner stopper 1 and protrudes to the outside.

A hole lO separate from the small hole 5 bored in the meat part 4 is provided on the back side of the meat part 4 of the inner stopper l, and a protrusion 111 communicating with this hole 10 is provided.
K is provided, this protrusion! It is possible to consider an arrangement in which the tip of the tube 8 is fitted into the tube 8.

Further, as the chemical liquid to be filled into the container 6 made of plastic, for example, equipped with the inner stopper 1, it is possible to consider an agricultural chemical diluted to a concentration that can be sprayed as is. Further, it is preferable that the concentration of the drug solution is in the range of approximately 0.1% to 5% as an active ingredient.

(Function) If the container 6 as described above is filled with a chemical solution such as an agricultural chemical that has been diluted to an appropriate concentration in advance and sold, the purchaser can simply remove the outer pillar and tilt the bottle. This means that the chemical solution can be easily sprayed. In addition, it is possible to spray liquid 15 like a watering can into a drain where the liquid 15 is running low in the container without spraying it all over the place.

(Example) Next, an example of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 designates an inner stopper, whose outer circumferential portion stands up to form a standing portion 2, and an outwardly directed flange 3 is formed at the upper end thereof. Meat part 4 of inner stopper L
A large number of small holes 5 are bored in the inner stopper 1, and this inner stopper 1 is inserted into the third hole.
As shown in the figure, when attached to the mouth of an original plastic container 6, the inside and outside of the container 6 are communicated with each other. In this embodiment, separately from the small hole 5, the small hole 5
A hole 7 is drilled at a position away from the hole 7, and a tube 8 is passed through the hole 7.

The length of the tube 8 is such that its base end (lower end) faces the bottom of the container 6.

The tube 8 also has a length (length) in which the proximal end reaches the space inside the container created by tilting or inverting the container 6 during use.
(See Figure 4) may also be used.

In the case of a container 6 with a hollow handle 9, the length of the base end reaching the handle 9 (see FIG. 5) may be sufficient.

When the inner stopper 1 having such a configuration is attached to the container 6 and the handle 9 of the container 6 is grasped and tilted.

The tube 8 is used so that its base end is in an air layer above the container 6. In this way, the outside air can be
Since it enters the flesh of the container 6 through the small hole 5, the chemical solution such as agricultural chemicals filled in the container 6 is sprayed to the outside through the small hole 5. By appropriately setting the length of the part of the tube 8 that protrudes from the inner stopper 1, it is possible to spray the chemical solution like a watering can without spraying it all over the place even if the amount of the chemical solution in the container 6 is low. An outer pillar can be attached.

In the embodiment described above, the tube 8 penetrates the inner stopper 1, but the present invention is not limited to this. FIG. 6 shows an example. In this embodiment, a hole IO separate from the small hole 5 bored in the meat part 4 is provided on the back side of the meat part 4.

This hole! 0 is provided, and the tube 8 is attached by fitting the tip of the tube 8 into this projection 11.

In this way, the tip of the tube 8 does not protrude outside the flesh part 4 of the inner plug l, resulting in an excellent appearance, and in addition to the functions shown in the previous embodiment, the inner surface of the outer column is tightly attached to the surface of the inner plug. It has the advantage of being able to open the bottle at a moment's notice.

The inner stoppers l explained above are all shaped to fit inside the mouth of the container, but instead of having this shape, for example, as shown in FIGS. 7 to 9, Such an inner stopper may be shaped to fit around the outer circumference of the mouth.
In this case, a liquid leakage prevention stopper 12 may be provided on the inner periphery of the inner stopper 1 as shown in FIGS. 8 and 9. Even in this case, the flesh part 4
The hole 5 provided in the hole 5 and the tube 8 can be attached using the same structure as described above.

In the present invention, a pesticide diluted to a predetermined concentration can be considered as the chemical liquid to be filled in the container 1. in this case,
In addition to insecticides, fungicides, herbicides, etc., chemical fertilizers can be considered as agricultural chemicals, and one or more of these may be used in combination.The degree of dilution of the agricultural chemicals varies depending on the chemical used. In order to avoid the hassle of opening the bottle and diluting it again to the practical use concentration, it is sufficient that the concentration is adjusted so that it can be used and sprayed as is by diluting it to the practical use concentration in advance, for example, About 50 ppm to 5% (preferably 0.1% to 5%) as an active ingredient
Generally, it is within the range of

Although the present invention has been described mainly for spraying agricultural chemicals, it is not limited to agricultural chemicals, and can of course be applied to the use and spraying of chemical solutions whose concentration has been adjusted in advance to a concentration for practical use. be.

(Effects of the Invention) As explained above, the present invention is an inner stopper equipped with a tube that communicates the inside and outside of the container when attached to the container, so once this is attached to the container, the only operation is to tilt the container. , can use and spray chemical solutions on meat parts. This makes it possible to sell chemical solutions such as agricultural chemicals diluted to an appropriate concentration from the beginning in containers.
