Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container filled with an emulsion, suspension, etc. that tends to adhere to the inner surface of the container.

[Conventional technology]

Agricultural chemicals are formulated into powders, wettable powders, water-solvents, granules, emulsions, smokers, etc. by comprehensively considering the purpose of use, chemical composition, physicochemical properties, physiological effects, safety, application method, etc. It is formulated into various formulations such as flowables (sols).

Recently, among the various formulations mentioned above, sol formulations that do not use organic solvents and do not generate dust, are safe for workers, and have excellent adhesion and stickiness to plants. These agents are now widely used in fields such as agricultural fungicides and herbicides. Generally, this flowable agent is a liquid formulation of a solid active ingredient, and is a concentrated aqueous suspension preparation in which the pulverized active ingredient is dispersed in water.

When the above-mentioned flowable preparation is actually sprayed on plants, it is generally diluted in water several hundred to several thousand times its volume. The above flowable formulations are usually
It is sold in bottles of approximately 250 to 5,000 ml.

For example, the 500ml bottle of Bashitatsuku Sol (manufactured by Kumiai Kagaku Kogyo Co., Ltd.) is a cylindrical plastic container, and its opening is not eccentric and there are no ribs inside the container, so the remaining drug can be removed. Difficult to confirm quantity. On the other hand, Takeda Beam Sol (manufactured by Takeda Pharmaceutical Co., Ltd.)
The ml container is a cylindrical plastic container with ribs inside the container, but the opening is not eccentric, making it difficult to check the amount of medicine remaining.

When using these drugs, after homogenizing the bottles twice, fill a container with a certain volume with water.
A predetermined amount of drug stock solution is injected into this and used.

[Problem that the invention attempts to solve]

By the way, in containers filled with emulsions, suspensions, etc., not only the above-mentioned flowable preparations, the emulsions and suspensions tend to adhere to the inner surface of the container, and even if a see-through container is used, It is difficult to see the liquid level. Therefore, if you do not know the amount of chemical remaining in use and inject a predetermined amount of chemical into a certain amount of water, you may not be able to estimate the specified value from the remaining amount of chemical, or the remaining amount of chemical may be less than the required amount. It was not possible to know that there was a shortage, and there were problems with chemical management or work schedules.

In view of the above-mentioned circumstances, the present inventor aims to provide a container that allows the remaining amount of a drug solution to be known almost accurately even if the container is not transparent.

[Means for solving problems]

The present invention has been made to achieve the above object, and its gist is a container for storing flowable preparations etc. that easily adhere to the inner surface, and the ribs or grooves extending along the inner surface are spaced apart from each other. a cylindrical body with a bottom formed in multiple stages; a mouth having a screw on the outer circumferential surface, the base of which is attached to the upper end of the body with the base biased toward one side of the outer circumference of the body; The container is provided with a spout that is screwed onto the mouth to seal the mouth.

[Effect]

In the container according to the present invention, the mouth is eccentrically attached to the body, so when looking inside the container from the mouth with the eccentric wide side facing you and the narrow side facing forward, The eccentric narrow side of the provided rib or groove and the liquid level can be easily seen. Furthermore, since the opening is eccentric, the medicinal solution can be poured out with the narrow side facing down, making it easy to pour out the medicinal solution without leaving any residue behind.

〔Example〕

1 and 2 show an embodiment of the container according to the present invention, FIG. 1 being a plan view of the container, and FIG. 2 being a longitudinal sectional view of the container. Reference numeral 1 in the figure is a bottomed cylindrical body, and the inner surface of the body 1 has ribs 2 that cover the inner peripheral surface.
A plurality of stages are provided at intervals.

The ribs 2 may be located at equal intervals as long as the capacity at each position is different, but it is preferable to provide them at equal intervals, such as every 100 ml for a 500 ml container, and every 50 ml for a 250 ml container.

At the upper end of the body 1, a base of a mouth 3 having a screw 3a on the outer circumferential surface is attached biased toward one outer circumferential side of the body 1.
a, a wide side 1b is formed. In the mouth part 3,
A socket-shaped spout 4, which has a screw 4a screwed into the screw 3a on the inner circumferential surface and seals the spout 3 via a gasket 5, is removably attached.

The container with the above structure has the wide side 1 with the spout 4 removed.
If you look inside with b facing you, the line of sight 6,
As shown by the dashed line 7, the inner surface of the trunk 1 can be viewed from above and below through a relatively large field of view. Therefore, the amount of the remaining chemical solution can be quickly and almost accurately determined from the positions of the ribs 2 and the liquid level.

FIG. 3 shows an example of a spout 4 suitable for use in the container of the present invention, in which a lever 8 projecting outward is integrally attached to the outer periphery of the spout. The lever 8 catches the finger when attaching and detaching the spout 4, so it can be firmly tightened and easily rotated when detaching. Further, the screws 3a, 4 are arranged so that the spout 4 seals the spout 3 when the lever 8 is positioned on the wide side 1b.
If a is formed, it can be immediately determined whether the airtight state is established or not. Furthermore, the lever 8 does not protrude beyond the outer circumferential surface of the body, making it possible to efficiently pack the product into boxes during distribution. Above spout 4
When using the cup as a measuring cup, as shown in FIG. 4, the lever 8 is shaped so that it can be easily pinched with fingers, thereby facilitating the measuring operation. Furthermore, it prevents chemical liquid from adhering to the fingers of the operator, and is also convenient for cleaning the inside of the spout after use. The spout 4 is screwed into the spout 3 shown in FIG.

Incidentally, when the container is made by blow molding plastic, the rib 2 is naturally formed in a concave shape on the outer peripheral surface of the body. Also, grooves may be formed instead of ribs, but ribs are easier to see than grooves. Further, in the above description, the horizontal cross section of the body 1 is circular, but it may also be oval, in which case the mouth portion is provided at an eccentric position along the long axis of the oval. However, polygonal shapes increase manufacturing costs and are not economically desirable.

The material of the container does not need to be particularly limited, but transparent or translucent synthetic resin is preferred from the viewpoint of workability, economy, etc. Particularly suitable are thermoplastic synthetic resins such as polyethylene, polypropylene, polyvinyl chloride, and polystyrene resins.

[Effect of idea]

As described above, the container according to the present invention allows the amount of liquid inside the container to be accurately determined by visually observing it from the mouth. It is suitable as a container for filling suspensions, etc., and has many advantages, such as being easy to attach and remove the spout and to pour liquid from the container.
