Description

[Detailed description of the invention] (Field of industrial application) The invention is particularly applicable to containers used for storing and dispensing liquids, such as liquid chemicals, pharmaceuticals, pesticides, cosmetics, toiletry products, detergents, foods, and others. The present invention relates to a relatively large capacity liquid dispensing container for refilling frequently used small containers for end consumers.

(Prior art) For small end consumer containers that are frequently used,
To avoid the inefficiency and uncertainty of using a funnel when dispensing liquid into small portions from a relatively large-capacity replenisher storage container, conventionally, the lid or stopper of the storage container was attached with a dispensing nozzle. It is being replaced with a stopper. However, it is troublesome to replace the stopper each time it is used, and it is not suitable for particularly busy work environments, so the power dispensing stopper is often left attached, resulting in the risk of volatilization of contents, contamination, and accidental falls. There were many inconveniences such as leaks. In order to solve this inconvenience, various types of dispensing containers that can be easily opened and closed, such as containers that can be opened and closed with a stopper that can be lifted up and down, have been developed since 1973.
No. 6472, No. 48-7453, No. 49-77057, No. 77057, No.
50-108845 and 51-14160, etc.
In addition, a container with a rotating spouting pipe was published in 1985-70025.
They have been proposed in Publications No. 56-40934 and No. 62-60552, and some have been widely put into practical use.

However, many of the above-mentioned containers with liftable closures,
Since the spout opens at the top of the lid, the container must be turned upside down when in use, and although it has utility as a small container for end consumers, it is extremely unsuitable as a relatively large container for dispensing. be. In Utility Model No. 50-108845, the spout opens on the side of the lid, so the liquid remaining near the opening after pouring flows down the side, staining the vessel wall and environment, creating a feeling of uncleanness. There is a drawback. In addition, the above-mentioned container with a rotating spouting pipe is equipped with a pump mechanism, which complicates the structure and increases manufacturing costs, or the liquid can be discharged only at a certain position of the spouting pipe, so the direction in which the container can be tilted is limited. Furthermore, there is a concern that liquid leakage may occur in the event of an accidental fall, as insufficient consideration has been given to liquid seals in rotating parts.

(Problems to be Solved by the Invention) In view of the various problems associated with the above-mentioned conventional techniques, the present invention is simple to use, easy to open and close, allows for free pouring direction, has a reliable liquid sealing function, and is designed to be used easily. It is an object of the present invention to provide a liquid dispensing container, particularly a relatively large liquid dispensing container, which is free from the risk of environmental contamination due to subsequent drip flow or liquid leakage during accidental overturning.

(Means for Solving the Problems) The liquid container with a dispensing beak of the present invention to achieve the above object consists of a container body made of a flexible elastic material and having a cylindrical neck at the top, and a cap. Therefore, in a liquid container having means for liquid-tightly attaching the cap to the mouth and neck, the cap includes: (a) a groove having a substantially U-shaped cross section concentrically along the inner wall of the mouth and neck; an annular groove, and a cylinder for a liquid passage that extends the inner peripheral wall of the annular groove and stands concentrically at the center thereof, and an undercut is provided near the upper edge of the inner wall surface of the annular groove. (b) an outer cylinder formed near the hem portion with another undercut that is inserted into the annular groove and engageable with the undercut; and the outer cylinder is slidably fitted to the outer wall of the cylinder. and an outer lid that can be freely rotated up and down, the inner cylinder being vertically disposed above the top plate, and having a pouring beak that extends laterally through the outer cylinder from a through hole bored in the upper part of the cylinder wall of the inner cylinder. When the outer lid is lowered, the top plate closes the upper end opening of the cylinder, and when the outer lid is raised, the liquid passage leading from the upper end opening of the cylinder to the dispensing beak is opened, and both under This feature is characterized in that excessive rise is restricted by engagement of the cut.

In order to further ensure that the top plate closes the opening at the upper end of the cylinder when the outer cover is lowered, a plug is provided in the center of the top plate, and the plug is tightly fitted into the opening. It is preferable to configure.

Further, as a means for attaching the cap to the mouth and neck, a flange extending outward from the annular groove of the inner lid is provided, and the flange is further extended downward to form a concentric U-shaped groove with a transverse face. It is also preferable that an annular groove is formed and the mouth and neck part is press-fitted and fixed into the annular groove.

Furthermore, it is also preferable that the lower end of the liquid passage cylinder opens near the bottom of the container body, and the tip of the spout beak is bent and directed downward or diagonally downward.

The structure of the liquid container with a dispensing beak according to the present invention will be described in further detail below based on the embodiments shown in the accompanying drawings.

The container of the present invention, whose elevational views are shown in FIGS. 1 and 1A, is composed of a container body 2 having a cylindrical neck part 1 at the top, and a cap 3 attached to the mouth neck part. be done. The container body 2 is formed of a flexible elastic material such as plastic, that is, a material that can be deformed due to compressive stress and quickly return to its original shape by removing the stress. Handles 4, 4' may be provided on the top and/or on the sides.

Fig. 2 is a plan view of the cap attachment part which constitutes the main part of the container of the present invention, Figs. The figure is a vertical sectional view of the inner lid 5, which is the main component of the cap, and FIG. 4 is a vertical sectional view of the outer lid 6, which is also the main component of the cap.
5 and 5A are vertical sectional views of a modified example of the cap of the container of the present invention in the closed and open states, respectively, FIG. 6 is a vertical sectional view of the inner lid 5', and 6A and 6B are FIG. 7 is a vertical sectional view of the outer cover 6', and FIG. 7A is a partially enlarged view thereof.

In FIGS. 2 to 4, the inner lid 5 is provided with an annular groove 7 on its periphery side, which is a groove having a substantially U-shaped cross section and concentrically along the inner wall of the container opening neck. The inner circumferential wall 8 of the annular groove is extended and a cylinder 9 is concentrically arranged therein. The upper and lower ends of the cylinder 9 are open, forming a liquid passage. In another embodiment of the invention shown in FIGS. 5-6, the lower end 9' of the cylinder 9 has a flexible tube 10 connected thereto.
(FIG. 1A) or the like to extend and open near the bottom of the container body 2. Further, an undercut 11 is provided on the inner wall surface of the annular groove 7 near its upper edge.

Next, the outer lid 6 has an outer cylinder 12 and an inner cylinder 13 concentrically arranged vertically from the top plate 14, and extends laterally through the outer cylinder from a through hole 15 bored in the upper part of the cylinder wall of the cylinder. It is equipped with a pouring beak 16. Soup beak 16
The tip may be bent as appropriate to point downward or diagonally downward. The outer cylinder 12 and the inner cylinder 13 are constructed by inserting the outer cylinder into the annular groove 7 of the inner cover and slidingly fitting the outer cover 6 into the outer wall of the cylinder 9.
It is molded into a shape and size that allows it to rotate. Further, an undercut 17 is formed near the bottom of the outer cylinder 12 so as to be able to engage with the undercut 11 in the annular groove. These undercuts 11 and 17 are
When the outer lid is lowered (see FIG. 2A), the top plate 14 closes the upper end opening of the cylinder 9, and when the outer lid is raised (see FIG. 2B), the spout beak 16 is closed from the upper end opening of the cylinder 9.
The undercuts 11 and 17 are arranged in a relationship such that the liquid passage leading to the undercut is opened and the undercuts 11 and 17 are engaged to prevent further rise of the outer lid. In other words, the elevating and lowering slot of the outer lid is controlled by the pouring beak 16.
It will be readily understood that it is preferable to make the diameter substantially equal to the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter of the diameter is substantially equal. In addition, in order to regulate the elevating and descending slot talk to a constant level, an annular protrusion 18 that is engaged with the upper edge of the outer peripheral wall of the annular groove 7 of the inner lid.
may be provided at an appropriate position on the outer peripheral wall of the outer lid outer cylinder 12.

5 to 7 show a modification of the present invention, in which the inner circumferential wall 8 of the inner cover annular groove 7 is extended inward at its middle level, and the outer cover is provided at an appropriate distance from the annular groove in the center. The cylinders 9 are erected at a distance sufficient for inserting the cylinders 13. Further, in addition to the adder cut 11, an annular groove 19 may be provided on the inner wall surface of the annular groove 7 near the bottom, which can fit into the undercut 17 of the outer lid. The annular groove is arranged so that it fits into the undercut 17 with the top plate 14 closing the upper end opening of the cylinder 9 when the outer cover is lowered (see FIG. 5).

Furthermore, the undercuts 11, 17 and the annular groove 19 all have circular arcs having substantially the same radius of curvature R ₁ in their cross-sectional shapes, as shown in FIGS. 6A, 7A, and 6B, respectively. It is desirable to form this in order to ensure liquid tightness.

Furthermore, in a preferred embodiment of the container of the present invention,
A plug 20 of a size that can be tightly fitted into the upper end opening of the cylinder 9 of the inner lid is provided in a protruding manner at the center of the lower surface of the top plate 14, and when the outer lid is lowered, the plug 20 is tightly fitted into the opening and the liquid passage is closed. Improves liquid-tight sealing in the event of blockage.

As a means for liquid-tightly attaching the cap 3 including the inner lid 5 and the outer lid 6 to the container mouth neck 1 as described above, the flange 21 extending outward from the annular groove 7 of the inner lid 5 is used. With or without forming a cap, it is sealed and fixed on the circumference of the mouth and neck part 1 by gluing, soldering, etc., or the outer diameter of the annular groove 7 is made slightly larger than the inner diameter of the mouth and neck part, and the cap is press-fitted. A method of attaching the flange 21 to the upper edge of the mouth and neck, or a method of attaching the flange 21 to the upper edge of the mouth and neck.
A collar 22 extending downward from the outer periphery of the annular groove 7 is integrally molded, and the mouth and neck part 1 is inserted into a concentric annular groove 23 consisting of a transverse vertical U-shaped groove formed between the collar and the outer periphery of the annular groove 7. There is a method in which a female screw carved on the inner periphery of the collar is screwed into a male screw provided on the outer periphery of the mouth and neck 1. However, the preferred mounting means that ensures the simplest and most reliable sealing and achieves stable fixation against the torque caused by the rotational movement of the outer cover and the stress caused by the vertical movement is press fit into the concentric annular groove 23, as shown in FIG. 2A. This is to engage and fix the bulged portion 24 of the mouth and neck portion that has been formed on the collar 22 with a protrusion 25 provided on the inner periphery of the collar 22. Further, as in the modified example shown in FIG. It is also possible to press and fix it to the upper edge of the mouth and neck, but the former is superior in terms of simplicity.

The container of the present invention is made of materials such as plastics, hard rubber, metals, porcelain, etc., particularly preferably plastics, and can be made by injection molding, blow molding, compression molding, etc.
It can be manufactured by any known and commonly used method such as casting, extrusion molding, and a combination thereof.

Although the basic configuration of the present invention has been described in the above description, modifications can be made as appropriate within the scope of this technical idea. For example, a person skilled in the art can easily incorporate a known pump mechanism.

(Function) To assemble the container of the present invention, first, the inner lid 5 is fitted into the mouth and neck part 1 of the container body 2, and if necessary, the restraining ring 2 is inserted.
7 is screwed onto the inner cover 5 in a liquid-tight manner, and then the outer cylinder 12 of the inner cover 5 is inserted into the inner cover annular groove 7, and the inner cylinder 13 is pushed down while being fitted into the cylinder 9. It is done by. The assembled container of the present invention is particularly suitable because the inner lid of the cap is attached to the mouth and neck with high liquid tightness, and furthermore, the upper end opening of the inner lid cylinder 9 is sealed by the top plate 14. In this embodiment, the plug body 20 is sealed more reliably. In addition, the cylinder 9 and the inner cylinder 13
Sliding contact/fitting surface with both undercuts 11, 17
Since the fitting part of the container protects the seal multiple times, there is virtually no leakage of the liquid contents regardless of the container's orientation. This dispensing container is typically used for liquid storage,
Because it is placed in a closed state during transportation and storage,
In order to prevent accidents such as the protruding spout beak being damaged or accidentally opening due to contact with other objects or accidental falling, the dispensing beak should be placed as shown in dotted lines in Figures 1 and 1A. It is best to close the outer cover by pressing down on it while it is turned inward. In such a closed state, the dispensing beak is protected by a handle or the like, and the stopper body 20 does not allow the outer lid to rotate freely due to the frictional resistance of the pressure contact with the cylinder 9, so the above-mentioned accident is effectively prevented. .

When using the container of the present invention, first, the outer lid 6 is pulled upward, and the stopper 20 is removed from the upper opening of the cylinder 9, thereby opening the liquid flow path leading from the cylinder 9 to the spout 16. This outer lid raising operation can be easily performed in a single operation without requiring abnormal force or multiple twisting operations. This suppresses the excessive rise of the outer lid and prevents it from separating from the inner lid. Since the outer lid in the raised state is freely rotatable and the liquid flow path is open in any direction, the dispensing beak can be rotated in an appropriate direction at will, tilting the container, and placing the tip of the dispensing beak into the small container. The liquid can be easily and reliably supplied to a small container with a small diameter by applying the container to the socket and pressing and deforming appropriate parts of the container body with fingers. Moreover, in the preferred embodiment shown in FIG. 1A, dispensing can be performed by placing the socket of the small container against the dispensing beak tip and deforming the container body under pressure without tilting the container of the present invention.

If the pressure on the container body is released when the proper amount has been supplied, the remaining liquid in the spout will be sucked by the elastic recovery force of the container body and flow back, so that it will not drip to the outside. Also, during pouring, the sliding fitting surface between the cylinder 9 and the inner cylinder 13 between the inner lid and the outer lid, and both undercuts 1 having the same radius of curvature.
The double seal formed by the close engagement of parts 1 and 17 effectively prevents liquid from leaking from the sliding portion.

(Effect of the invention) Since the liquid container of the invention has the above-described structure and has the above-mentioned function, there is no need for a funnel when dispensing and replenishing liquid from a relatively large storage container to a small end-user container. In addition, there is no need to replace the lid or stopper with a special dispensing accessory stopper, and there is no need to turn the container upside down when dispensing, making it possible to perform tasks reliably, easily and quickly with a simple tilt or no tilt. It became. In addition, it is extremely easy to open and close the liquid flow path, the direction of liquid injection can be selected at will, and there is no contamination of the container wall or environment due to dripping of residual liquid after the dispensing process is completed, and even higher liquid-tight sealing properties are achieved. This eliminates concerns about liquid leakage due to vibrations or accidental falls during storage and transportation. Therefore, the container of this invention can be used in general households, factories that handle chemicals, laboratories, schools, etc., hospitals and clinics that handle pharmaceuticals, restaurants and kitchens that handle food, hotels and offices that handle cosmetics and toiletry products. hair salons, barber shops, beauty salons, etc., cleaning shops that sell detergents, etc.
It provides convenience in particularly busy working environments, such as farmers who handle pesticides, and has a wide range of applications.
Instead of liquid products that were distributed by manufacturers by filling them into large quantities of small containers for end consumers, the liquid products according to the present invention can be filled into medium to large storage and replenishment containers and marketed, and end consumers can dispense and use them. As a result, significant cost reductions have been achieved due to the mass reduction of small containers, and this will usher in a kind of distribution revolution.
