Description

  The present invention relates to a liquid ejector that enables two-liquid mixture ejection and one-liquid selective ejection.

In an ejection container that can eject two liquids such as cosmetics and hair dye alone or in combination as required, the two containers with the pressing head attached to the upper end of the stem are held together. A pressing plate that engages the lifting surfaces of both the pressing heads is mounted between the pressing heads, and the desired liquid content can be dispensed from one container by pressing one of the pressing heads. 2. Description of the Related Art Conventionally, a two-liquid mixing / one-liquid selective ejection container in which the liquid contents are ejected and mixed from both containers by ejecting and pushing down a push-down plate has been known (see, for example, Patent Document 1).
JP 2002-59881 A

  However, in the above-described conventional ejection container, when the cover cylinder (51) is removed, there is a possibility that the pressing head or the pressing plate is erroneously pressed.

  In consideration of the above problems, the present invention attaches an operating member to the cover cap so that the pressing head and the pressing plate cannot be inadvertently touched, and the two-liquid mixed jetting is performed. It is an object of the present invention to provide a two-liquid ejector that can reliably and easily switch the liquid ejection and prevent malfunctions.

In order to solve the above-described problems, the present invention provides a liquid ejector as a pair of ejection containers including a container body and a nozzle head having a ejection nozzle attached to the container body via a mounting cap, and the ejection A liquid ejector comprising a cover cap that covers a container and an operation member that contacts the upper surface of the nozzle head, wherein the cover cap is cut out above the top wall and the front and rear side walls to expose both nozzle heads. The cover cap is provided with a support portion for rotatably mounting the operation member at the front end of the notch portion edge of the top wall, and the cover cap is provided above the notch portion edge of the side peripheral wall. A stopper is provided, and the operation member includes an attachment portion and an operation portion that can slide back and forth with respect to the attachment portion, and is extendable and retractable by rotating the operation member upward. , Expose the top surface of both nozzle heads To allow selection pressing operation of the nozzle head, the time of reduction of the operating member, the operating portion of the operating member is locked in contact with the stopper of the cover cap, at the time of extension, the locking is released operating portion is disengaged from the stopper , the operating member is capable Mawarido operation downward, it adopted a structure characterized by being adapted to both the nozzle head can pressing operation at the same time.

As a specific embodiment of the operation member , the operation portion of the operation member is slidably fitted into a support rod of the attachment portion, and a protruding portion that engages with a stopper is provided on the rear end side portion. Adopt the configuration to do.

The operation member can be expanded and contracted by the operation of pulling out the operation unit, and is attached to a cover cap that covers two nozzle heads so that it can rotate. When the operation member is reduced, it is locked by a stopper of the cover cap. Thus, the downward rotation operation is prevented, and when it is extended, it can be removed from the stopper and the downward rotation operation can be performed, and both nozzle heads can be pushed down simultaneously.
Further, by rotating the operation member upward, the upper surfaces of both nozzle heads are exposed, and either one can be selected and a pressing operation can be performed.

  Therefore, by attaching the operation member, it becomes possible to select three states of simultaneous pressing, selective pressing, and blocking prevention of both nozzle heads, and each operation can be performed reliably and easily. Became.

Locked.

When the two liquids are mixed and ejected when the content liquid is ejected, as shown in FIG. 7, when the operation piece 41 is pulled out, the projecting portion 54 comes off from the step portion 32 of the side peripheral wall 26 and the lock is released. The operation member D can be pushed down.
Next, when the operation member D is pushed down, the presser plate 44 simultaneously pushes down both the nozzle heads A3, and the content liquid is ejected from both the ejection nozzles 10.

  The ejected content liquid can be received in the front of the ejection nozzle 10 with a cup or palm, mixed, and then applied to a required location.

  Next, when only one liquid is ejected, as shown in FIG. 8, the top wall 11 of both nozzle heads A3 is exposed when the operation piece 41 of the operation member D is rotated upward without being pulled out. When one of the nozzle heads A3 is pushed down, the content liquid is ejected from the ejection nozzle 10 of the nozzle head A3.

Next, a modified embodiment will be described.
In the above embodiment, the pair of ejection containers A are stored in the outer container B, but in this embodiment, two container bodies are connected by a cover cap.

9 and 10, Aa is an ejection container, Ca is a cover cap, and Da is an operation member.
The ejection container Aa is composed of a container body A1a, a pump attached to the container mouth through the mounting cap A2a, and a nozzle head A3a attached to the pump stem, as in the above embodiment. Yes.

  The container body A1a is composed of a mouth portion 1a, a shoulder portion 2a, a trunk portion 3a, and a bottom portion 4a. The shape of the cross section of the shoulder portion 2a and the trunk portion 3a is formed by a straight portion 5a and an elliptical arc portion 6a. In addition, a bulging portion 60 is formed in the elliptical arc portion 6a of the shoulder portion 2a, and a lower portion thereof is a step portion 61 provided on the upper end edge of the trunk portion 3a.

  Since the mounting cap A2a, the pump, and the nozzle head A3a are the same as those in the above-described embodiment, only the suffix “a” is attached to the reference numeral and the description is omitted.

  The two ejection containers Aa are connected to each other by joining the respective straight portions of the container main body A1a and the nozzle head A3a, as in the above embodiment.

  The cover cap Ca is provided with a concave portion 62 that engages with the bulging portion 60 of the shoulder portion 2a at the lower end portion, and the lower end 63 comes into contact with the step portion 61 at the upper end of the trunk portion 3a. The point is the same as that of the said embodiment.

  In connecting the ejection container Aa, the elliptical arc part 6a of the shoulder part 2a of each ejection container is fastened with the cover cap Ca, and the bottom part 4a of the container body Aa is placed on the holding base 64. Also good.

  In the liquid ejector of the present embodiment, the two ejection containers can be directly connected by the cover cap, and in use, the same effect as that of the above embodiment can be obtained.

In the above-described embodiment, the presser plate 44 is connected to the operation rod 45 of the operation member, but the presser plate may be omitted.
In that case, even if the gap between the nozzle heads A3 becomes large, both the nozzle heads A3 are simultaneously pushed down by the operation piece 41, and the content liquid is ejected from the ejection nozzle 10.

  Moreover, in the said embodiment, although the content liquid was ejected from the ejection nozzle, you may make it spray by attaching a spray nozzle to a nozzle head.

  A cover cap that covers the nozzle head is provided with a notch, and an operating member is attached to the front wall front end of the notch so that the operating piece can be freely engaged with and disengaged from the stopper of the cover cap. Simultaneous pressing of the nozzle head, prevention of pressing by engaging with the stopper, and selective extrusion can be switched reliably, expanding the range of use of the two-component mixing jet, not only in cosmetics, but also in food and other fields Now available.
