Description

  The present invention relates to a two-component mixed discharge container that separately stores two types of liquid and discharges them simultaneously.

  Liquid discharge devices are widely used as containers for clothing finishes, residential liquid detergents, etc., and there are two types of residential liquid detergents: a first liquid containing hydrogen peroxide and an alkaline second liquid. In some cases, the two liquids are mixed at the time of use for effective cleaning.

  The two-component mixed discharge container used for this purpose is a trigger type injection container that stores two types of liquids in separate containers and discharges them at the same time. Two types of liquids are sucked into two chambers divided into two, respectively pressurized, discharged into a mixing path, and two mixed liquids are ejected from an ejection nozzle (Patent Document 1). However, in this two-liquid mixing / discharging container, gas is generated during mixing of the two liquids in the mixing path in the trigger type ejection device, and it is necessary to vent the gas.

  On the other hand, there is a two-liquid mixing and discharging container in which two kinds of liquid are separately ejected from two ejection holes and mixed after ejection (Patent Document 2). In the two-liquid mixing / discharging container, the two liquids are mixed almost simultaneously with the two liquids being separately ejected from the ejection holes by adjusting the ejection range of the liquid from the ejection holes. For this reason, according to this two-component mixed discharge container, it is possible to eliminate the need for degassing in the container.

  On the other hand, in recent years, refill containers have become widespread in order to reduce environmental impact and reduce product prices. As an aspect of using the refill container in the two-type mixed discharge container, there is a method of refilling the content liquid from the refill container into the container body of the original two-type mixed discharge container. It is desirable to replace the discharge device of the two-component mixed discharge container with a refill container.

  However, when the discharge device is replaced with the refill container of the two-liquid mixed discharge container, the two liquids are mixed inadvertently if the connection between the two types of liquid refill containers and the discharge device is mistaken. In addition, inadvertent mixing of the two liquids also occurs when liquid dripping from the discharge device is mixed into the refill container.

  With respect to such a problem, an object of the present invention is to minimize the inadvertent mixing of two liquids that may occur when a refill container is used in a two-liquid mixing and discharging container.

  The present inventor attaches one of the dip tubes to the container main body when supplying two types of liquid from the container main body using the dip tube to the two-liquid discharge mixing / discharging container having two discharge holes and discharge paths. In addition, it has been found that if the other is attached to the discharge device, the possibility of misconnection between the container body and the discharge device can be completely eliminated.

That is, the present invention includes a first container main body and a second container main body that independently store liquid, and a discharge device that is attached to the mouths of the first container main body and the second container main body. A liquid mixing and discharging container,
The discharge device has a first discharge path for discharging the liquid stored in the first container body from the discharge hole and a second discharge path for discharging the liquid stored in the second container body from the discharge hole. A dip tube for the first container body is attached to the end of the first discharge path on the container body side,
Provided is a two-component mixed discharge container in which a dip tube is attached inside a second container main body.

  According to the two-component mixed discharge container of the present invention, the discharge device mounted on the first container main body and the mouth of the second container main body is a liquid contained in the first container main body in the discharge device. A first discharge path for discharging the liquid from the discharge hole and a second discharge path for discharging the liquid contained in the second container body from the discharge hole, and the end of the first discharge path on the container body side In addition, since the dip tube to be inserted into the first container body is attached and the dip tube is attached to the inside of the second container body, when the discharge device is attached to the mouth of the container body, The dip tube for the first container body attached to the discharge device is not inserted into the second container body to which the dip tube is already attached, and is always inserted into the first container body. . Therefore, even when the refill container is used as the first and second container main bodies and the discharge device is mounted on the first and second container main bodies which are refill containers, the first and second in the discharge device. The discharge path and the first and second container bodies are not mistakenly connected, and inadvertent mixing of the two liquids can be completely prevented.

Hereinafter, the present invention will be specifically described with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.
1A is a front view and FIG. 1B is a side view of a two-liquid mixing / discharging container 1A according to an embodiment of the present invention. The two-component mixed discharge container 1A includes a container main body 2 and a discharge device 3A. The discharge device 3A is detachably screwed into the mouth 21 of the container main body 2, and the bottom of the container main body 2 has an outer surface on the bottom. As shown in FIG. 2, the container main body 2, the discharge device 3 </ b> A, and the heel member 4 can be removed.

  As shown in FIG. 3, the container body 2 is composed of a combination of the first container body 2A and the second container body 2B, and the first container body 2A and the second container body 2B are independent of each other. It has a flat bottomed cylindrical shape having an accommodating portion, and can be separated into two parts as shown in FIG. The mouth walls of the first container body 2A and the second container body 2B are provided with a recess 22 and a protrusion 23 that fit together, and the first container body 2A and the second container body 2B The combination form is stabilized.

  The discharge device 3A reciprocates the piston in the cylinder by pulling and releasing the trigger 31 indicated by an arrow in FIG. 1 (b), thereby causing the first and second container bodies 2A, 2B to pass through the dip tubes 32A, 32B. A trigger-type discharge device that alternately draws liquid into the cylinder 34 and discharges the liquid from the first and second discharge holes 33A and 33B by pressurizing the liquid sucked into the cylinder 34 with the piston 35. is there. In the discharge device 3A, the liquid suction from the first and second container bodies 2A, 2B to the cylinder 34 and the discharge of the liquid sucked into the cylinder 34 from the first and second discharge holes 33A, 33B are as follows: The mechanism can be the same as that of a known trigger type discharge device, but in this discharge device 3A, liquid is sucked up from the two container bodies 2A and 2B, and each liquid is discharged separately from the two discharge holes 33A and 33B. As shown, two discharge paths 36A and 36B are formed in the discharge device 3A in parallel. The configuration of the discharge device itself having the two discharge paths 36A and 36B as described above can be the same as that of the spray container shown in FIG. 1 of JP-A-8-84946, for example.

  Regarding the configuration of the first and second discharge holes 33A and 33B through which the first and second discharge paths 36A and 36B communicate, respectively, the discharge ranges of the liquid discharged therefrom overlap, and these are the two discharge holes. Similar to the spray container disclosed in JP-A-8-84946, the opening diameters of the two discharge holes 33A and 33B are appropriately determined so that they are mixed at the same time as they are discharged from 33A and 33B. A protruding piece may be erected between the two discharge holes 33A and 33B.

  Further, as shown in FIG. 2, the first and second discharge holes 33A and 33B are set to the container body 2 so that the discharge device 3A can be fixed to the container body 2 as shown in FIG. Is provided with a cap 5 that presses the inner stopper in the discharge device 3A against the mouth 21 of the container body 2 and fixes the discharge device 3A to the container body 2.

  In the present embodiment, of the two discharge paths 36A and 36B in the discharge device 3A, as shown in FIG. 2, the first discharge path 36A for discharging the liquid in the first container main body 2A is disposed on the container main body 2A side. A dip tube 32A for the first container main body 2A is fixedly attached to the end, but the end of the second discharge path 36B for discharging the liquid of the second container main body 2B on the container main body 2B side. The dip tube 32B is not attached to the part, and the dip tube 32A is not attached to the inside of the first container body 2A, but the dip tube 32B is fixed to the inside of the second container body 2B. Attached. Further, a check valve 37 that allows the liquid in the container body 2B to be discharged is provided at the upper end of the dip tube 32B attached to the inside of the second container body 2B. However, it is also provided downstream of the dip tube 32A for the first container body 2A (not shown).

  As a result, when the discharge device 3A is attached to the mouth portion 21 of the container main body 2 in which the first and second container main bodies 2A and 2B are combined, the dip tube 32A for the first container main body 2A is already in the dip tube. Since there is no room for insertion into the second container body 2B to which 32B is attached, it is always inserted into the first container body 2A. Therefore, inadvertent mixing of the two liquids due to the dip tube 32A for the first container body 2A being erroneously inserted into the second container body 2B can be completely eliminated. Therefore, for example, when the discharge device 3A is attached to the container main bodies 2A 'and 2B' provided as refill containers as shown in FIG. 5, inadvertent mixing of the two liquids can be completely eliminated.

  The two-liquid discharge mixing container 1A of this embodiment is used as follows. First, by repeatedly pulling the trigger 31 in the direction of the arrow in FIG. 1B and releasing the trigger 31, the liquid stored in the first and second container bodies 2 </ b> A and 2 </ b> B is discharged into the discharge device 3 </ b> A. The liquid sucked up to the cylinder 34 is discharged from the separate discharge holes 33A and 33B simultaneously through the discharge paths 36A and 36B. At this time, since the discharge ranges of the two discharge holes 33A and 33B overlap, the liquid discharged from the discharge holes 33A and 33B is mixed almost simultaneously with the discharge.

  When the liquid in the container main bodies 2A and 2B is consumed, the cap 5 is turned and loosened, and the discharge device 3A is removed from the container main bodies 2A and 2B as shown in FIG. Then, as shown in FIG. 5, the lids 6 are removed from the first and second container bodies 2A ′ and 2B ′ provided as the refill containers, and the discharge device 3A is installed at the mouths of the container bodies 2A ′ and 2B ′. Attach and tighten the cap 5 to fix the connection between the discharge device 3A and the container main bodies 2A ′ and 2B ′. At this time, the dip tube 32A for the first container main body attached to the discharge device 3A is inserted into the first container main body 2A ′, and the discharge path 36B for the second container main body in the discharge device 3A. The end on the container body side is pressed onto the dip tube 32B in the second container body 2B ′. In this manner, the liquids can be mixed and discharged again from the container main bodies 2A 'and 2B' without inadvertently mixing the two liquids.

The present invention can take various aspects.
For example, as a configuration of the ejection device, as in the ejection device 3B shown in FIG. 6, a front end wall 38 that collides liquid ejected from the ejection holes 33A and 33B is provided in front of the ejection holes 33A and 33B. The liquid mixture discharge nozzle 39 may be formed on the tip end wall 38, and the two liquids that collide with the tip end wall 38 and mixed may be discharged from the liquid mixture discharge nozzle 39. Thereby, the completely mixed liquid can be ejected from the mixed liquid discharge nozzle 39.

  Furthermore, the discharge device is not limited to the trigger type, and a pump type discharge device may be used. 7A is a front view and FIG. 7B is a side view of a two-liquid mixed discharge container 1C provided with a pump-type discharge device 3C. In this pump-type discharge device 3C, two pump devices comprising a cylinder and a piston are incorporated, and these pistons are configured to be pushed by a common pressing portion 40.

  On the other hand, regarding the container body, the first and second container bodies 2A and 2B may be formed of a transparent material so that the remaining amount of liquid in each of the first and second container bodies 2A and 2B can be understood. You may color-code so that two liquids may be distinguished easily.

  In addition, when only one of the first and second container bodies 2A and 2B is consumed first, only the one of the consumed container bodies 2A can be replaced. A refill container for 2B may be provided separately. On the other hand, when the same amount of the liquid contained in the first and second container bodies 2A and 2B is discharged, the first and second container bodies 2A and 2B are not necessarily configured as separate parts. There is no need, and the outer shape may be integrated. Therefore, in the above-described two-liquid mixing container 1A, the first and second container bodies 2A and 2B and the eaves member 4 may be fixed. It should be noted that the first and second container bodies 2A and 2B are preferably detachable from the viewpoint of facilitating cleaning of the container at the time of disposal.

  The first and second dip tubes 32A and 32B can be either flexible or hard, but need to be inserted into the container body 2A when replacing the container bodies 2A and 2B. As for the dip tube 32A, it is preferable to use a substantially straight and hard tube in terms of easy insertion and avoiding the problem of splashing of the liquid remaining in the tube.

  The two-component mixed discharge container of the present invention is useful as a container for two-component residential detergents, bleaching agents, clothing finishing agents and the like that are used by mixing two kinds of liquids.
