Description

TECHNICAL FIELD The present invention relates to a liquid container, and more particularly, to a liquid container configured to store a plurality of kinds of liquids without mixing them. is there.

(Prior Art) Conventionally, when used in a mixed state, when two or more kinds of substances (particularly liquids) are not used, since deterioration occurs due to chemical change etc. after a certain period of time in the mixed state. Are stored separately, and the deterioration and state change of each substance can be suppressed, and a desired amount can be sufficiently exerted by mixing in an appropriate amount at the time of use. Examples of such substances include chemicals and the like, for example, a two-component adhesive, a developing solution and a fixing solution for processing a photographic light-sensitive material, and the like.

The developer of the processing solution for a photographic light-sensitive material, which can be mentioned as a prominent example, is a development accelerator as an auxiliary agent to a developing agent,
Preservatives, antifoggants and the like are added, and as the fixing solution, those in which a preservative, a hardener and the like are added as auxiliary agents to the fixing base are used. Then, these processing stock solutions are those whose chemicals as the components are easily deteriorated in concentration. For example, the working solution actually used in an automatic developing machine or the like is prepared by dissolving the processing stock solution in water as appropriate. To use.

Usually, a processing solution for a developing solution is prepared by, for example, generally mixing three stock solutions A, B, and C or two stock solutions A and B and water in appropriate amounts, and in the case of a fixing solution, generally, for example, The two stock solutions A and B are mixed with water to obtain a treatment solution that is actually used. Usually, this blending is carried out by an automatic blending machine immediately before the processing liquid is supplied to, for example, an automatic developing machine, but this is, for example, the deterioration caused by the above-mentioned processing liquids coming into contact with air is suppressed as much as possible, and the processing capacity is sufficient It is done to show it.

Therefore, in the conventional preparation of the above-mentioned processing solutions, for example, the mouth of the container containing the stock solution of the developing solution or the fixing solution is placed downward, and the solution is supplied to the preparation tank of the automatic preparation machine by dropping or inserted into the container. Suck it up with the pipe, and add a fixed ratio of water to the supplied undiluted solution,
Furthermore, a method of preparing a liquid while agitating it by a liquid circulation of a pump is often used. Then, for example, when the treatment liquid is separately contained in a plurality of containers having relatively high rigidity and good handleability, a predetermined amount of the liquid is poured from each of the containers to prepare the liquid, or the liquid is prepared in advance. For example, a plurality of containers each containing a fixed amount of liquid having a set amount of liquid are set in an automatic blender with their mouths facing down.
Also, when a plurality of flexible containers made of synthetic resin having flexibility are used, one of these flexible containers is packed in a high-rigidity cardboard case, for example, and the containers are inverted and set at one time. The method of doing was also used.

The term "relatively high" in the present specification means that the container shape cannot be maintained without the contents, or the container shape cannot be maintained without auxiliary equipment in comparison with a synthetic resin container. Then, it means that the shape can be maintained by itself, and the rigidity is equal to or higher than the extent that deformation or the like does not occur during handling with fingers or the like.

In order to perform a smooth operation when preparing the above-mentioned treatment liquid, what is required of the container containing the stock solution is, for example, that the liquid discharge time is short, there is no residual liquid in the container, and the handling is good. Also, when a plurality of containers are packed into one pack, various conditions are required such that they are firmly fixed and the liquid outlet is not displaced.

In the case of the flexible container, there are problems in the generation of residual liquid and the handling property, and there is a problem that it is necessary to work to combine a plurality of the flexible containers into one pack. High containers, such as relatively hard and easy-to-handle containers made of rigid resin such as high-density polyethylene, have different containers for each type of liquid, so each individual container has good handleability. In both cases, the operation of the container for preparing the liquid for each kind of liquid, that is, the operation of removing the cap, injecting the liquid, and setting the container is required for each container, which causes a problem of complexity.

On the other hand, for example, Japanese Utility Model Publication No. 51-15691 and Japanese Utility Model Publication No. 49-3964 disclose containers devised to solve the above problems. In the case of the former Japanese Utility Model Publication No. 51-15691, a container made of a relatively rigid plastic resin has two storage chambers, and one cap simultaneously closes the mouths of both storage chambers. Although a container having such a structure is shown, in order to manufacture the container body shown in the publication, it is difficult to integrally mold the container body, and each moldable portion must be separately molded before being assembled. Since it is a structure that must be formed, the formability is extremely poor and there is a cost problem. Moreover, it is difficult to make the two outflow holes structurally large because the two mouths are simultaneously sealed by the pointed plug part that is provided at the center of the inner surface of the one screw-in type cap. Moreover, there is a problem that it is difficult to shorten the liquid outflow time because the opening diameter is small.

In the case of the latter Japanese Utility Model Publication No. Sho 49-3964, a container made of a relatively high-rigidity plastic resin has a plurality of storage chambers, and one cap has a mouth portion of both storage chambers. Although a container having a configuration capable of simultaneously closing the above is shown, the overall shape of the container body shown in the publication is not only affected by the shape of each partial portion that constitutes each accommodation chamber, Since the parts are only locked by the concavo-convex fitting such as the protrusions formed on the wall surface, the assembled state is not so strong, and the problem of handling is left.
In addition, the entire container neck that the cap engages is composed of a collection of necks of the storage chambers, the assembled state of each part, that is, each part forms a part of the container contour and the influence of external force. However, there is a problem in the engagement performance of the cap and the sealing performance of the mouth portion due to the influence of molding accuracy.

Further, in general, the opening diameter of the mouth can be increased in order to shorten the liquid outflow time from the container, but the larger the lid member that closes the mouth, the larger the screw-type lid member, for example. In this case, since a large amount of force is required when attaching and detaching, there was a problem of attachment and detachment operability.

(Purpose of the Invention) The present invention has been made in view of the above problems, and has a good moldability of the container body, can be manufactured at a low price, has a reliable sealing between the storage chambers, and has a removable performance of the lid member. It is an object of the present invention to provide a liquid container which can shorten the dripping time (the liquid outflow time when the mouth portion is lowered) without lowering it and which is excellent in handleability.

(Constitution of the Invention) An object of the present invention is a liquid container formed by integral molding and having an opening at the upper end, wherein the container body of the liquid container has a plurality of storage chambers with a vertical partition wall inside. And the upper end edge of the partition wall is substantially flush with the end edge of the opening, and a core partition wall having at least a screw portion is provided at the center of the opening. And a lid member that closes the opening is tightened by a screw fastener having a large-diameter grip portion and screwed into the screw portion. be able to.

Hereinafter, embodiments of the present invention illustrated in the drawings will be described in detail.

FIG. 1 is an exploded perspective view of a liquid container according to an embodiment of the present invention.

A liquid container 1 shown in FIG. 1 is made of a material having a relatively high rigidity such as high-density polyethylene by integral molding, and has a cylindrical container body 2 having an entire upper opening, a disc-shaped pressing plate 4, and a packing. It is composed of a lid member 3 composed of 5 and a screw fastener 7 for attaching the lid member 3 to the container body 2.

Further, the container body 2 has a core material partition wall 11 forming a through hole in the center thereof, and the core material partition wall 11 and the outer peripheral wall
Partition walls 13, 14, 15 extending in the longitudinal direction of the container extend in the radial direction of the cylinder so as to be connected to the bottom portion 16 and bridge between
One accommodation room B, C, D is formed. Further, the upper end edges 13a, 14a, 15a of the partition walls 13, 14, 15 and the upper end edge 11a of the core material partition wall 11 and the upper end edge 2a of the outer peripheral wall 20 are located on substantially the same plane.

A female screw portion 12 is formed on the core partition wall 11 at the mouth side (a portion closer to the upper side in the drawing).

The lid member 3 is made of, for example, high-density polyethylene, and has a relatively thick wall having a circular hole 4a in the center so as to have rigidity. And the packing 5 having

The screw fastener 7 has a male threaded portion 10 that is screwed into the female threaded portion 12, and a pressing body portion 8 having a diameter larger than the diameter of the circular hole 4a is provided on an upper portion of the male threaded portion 10. A gripping portion 9 for performing a screwing operation or a detaching operation with a finger or the like is provided above the pressing body portion 8. The grip 9 is
It is composed of three arms that project in the radial direction of the screw, and the maximum diameter of the arms is also configured such that at least the radial deviation of the male screw portion 8 is large.

The mouth portion of the container body 2 covers the packing 5 and the pressing plate 4, and then the tightening tool 7 is attached to the female thread portion 12.
By screwing with, it is possible to apply a sufficient tightening force without using a tightening device or the like, and the packing 5 closely adheres to each of the upper end edges and is well closed.

In the liquid container 1, for example, three types of liquids, A liquid, B liquid, and C liquid, which are undiluted developers, are separately stored in the storage chambers B, C, and D, and A liquid, B liquid, and C liquid are stored. When the amount between the liquid and the liquid is the amount corresponding to the mixing ratio at the time of use in advance, the lid member 3 is removed without using a tool, and for example, in the injection port above the liquid preparation tank of the automatic mixing machine. Just tilt the container body,
Since the mouth portion is large, the liquid can flow out very quickly and the three liquids can be injected at the same time. Further, it is also possible to insert a suction nozzle for each liquid to the bottom of each of the storage chambers B, C, D to suck up and prepare a liquid.

In any case, the three liquids in each storage chamber are isolated and stored in one container, so the container can be handled only once.
The complexity of handling the container has been improved compared to the past, and further,
It is possible to eliminate troubles such as making a mistake in the type and amount of the liquid prepared, and to perform reliable liquid preparation.

It should be noted that a desired amount of water to be injected into the solution adjusting tank can be supplied at a proper timing with respect to the injection of the three liquids, and further can be appropriately stirred by, for example, a circulation pump or the like to perform good liquid preparation.

In the above-mentioned embodiment, the container body 2 has a cylindrical shape. However, the present invention is not limited to a cylindrical shape, and may have a triangular shape, a rectangular shape, or a pentagonal or higher polygonal shape.

In the above-described embodiment, the case of the three storage chambers B, C and D has been described, but the present invention is not limited to this embodiment.

Further, although the grip portion 9 in the embodiment is composed of three arms, the present invention is not limited to this, and it is needless to say that various modifications can be made.

In the present invention, the lid member 3 is not limited to the configuration shown in the above embodiment, but can be modified as appropriate, and can be constructed as shown in FIG. 2, for example.
In the structure of the lid member 30 shown in FIG. 2, the central circular hole 40a is made thick, and a plurality of ribs 41 are provided in a tapered shape extending radially outward from the circular hole 40a and at appropriate intervals. Has been. Further, the lid member 30 has an outer periphery protruding annularly on the side opposite to the side where the ribs 41 are formed, and an overlapping portion 42 that overlaps the outer peripheral wall 20 of the container body 2 is formed. Further, the packing 5 shown in FIG. 1 is attached to the inner surface. According to the structure in which the rib 41 is provided and the pressing plate / packing integrated type as described above, the tightening force by the screw tightening tool 7 can be set without increasing the thickness as in the pressing plate 4 shown in FIG. It can be added to the whole part, and the assemblability to the container body 2 is also improved.

Further, the present invention is not limited to the container for storing the developing solution and the fixing solution, but can be applied to the container for storing any liquid.

(Effects of the Invention) As described in detail above, the liquid container of the present invention is a liquid container formed by integral molding and having an opening at the upper end, and the inside of the container body has a plurality of storage chambers with vertical partition walls. And the upper end edge of the partition wall is substantially flush with the end edge of the opening, and a core partition wall having at least a screw portion is provided at the center of the opening. In addition, since the lid member that closes the upper end opening can be tightened by a screw fastener that has a large-diameter gripping portion and is screwed into the screw portion, it is possible to apply a plurality of types of liquid to one It can be stored without mixing in a container, has good sealing performance, improves the complexity of handling the container when preparing multiple types of solutions, and makes sure that both the type of preparation and the volume are correct. Without liquid be able to. Moreover, the container body can be easily integrally formed, and the mouth of each accommodation chamber can be made larger than that of the conventional container, so that the liquid outflow time can be shortened.
