Description

  The present invention relates to a liquid ejector that enables two-liquid mixed 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 content liquid is discharged 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 conventional ejection container, since the area of the push-down plate is not large, there is a possibility that fingers are displaced from or separated from the push-down plate when the two liquids are mixed and ejected.

  In consideration of the above-mentioned circumstances, the present invention attaches a presser plate that covers both nozzle head top walls to the shoulder parts of the liquid ejector so that the two liquid mixed ejection and the one liquid selective ejection can be switched reliably. An object of the present invention is to provide a liquid ejector.

  In order to solve the above-mentioned problems, the present invention combines a pair of ejection containers each having a container body and a nozzle head equipped with the ejection nozzle as a liquid ejector, and a liquid mounted on a shoulder part. It is an ejector, and the shoulder part adopts a structure characterized in that a presser plate that can push down both nozzle head top walls is attached so as to be rotatable.

  As an embodiment of the shoulder parts, the shoulder parts consist of a top wall and a side wall, and the top wall has a pair of jetting container insertion holes perforated, and a presser plate can be freely rotated between the two insertion openings. The structure characterized by the standing support plate standing is employ | adopted.

  In order to regulate the ejection direction of the ejection nozzle, a notch is provided at the upper end of the side wall of the nozzle head, and the presser plate engages with the notch, and a protrusion that regulates the direction of the ejection nozzle is provided. A configuration characterized by the above is adopted.

  A presser plate is attached to the shoulder part of the liquid ejector so that the nozzle heads can be connected with each other clearly and the nozzle heads can be disconnected. It is now possible to reliably switch between ejecting two liquids and lowering one nozzle head and selecting and ejecting one liquid.

  Also, the direction of the ejection nozzle can be changed freely by rotating the nozzle head, and when both nozzle heads are connected by a presser plate, they can be fixed in a certain direction. The nozzle heads can be pressed down simultaneously to eject two liquids, and one of the nozzle heads can be pressed down to selectively eject one liquid in a desired direction.

Next, the liquid ejector of the present invention will be described with reference to the drawings.

As shown in FIG. 4A, the presser plate D is rotatable between an upper position that engages with the nozzle head and a lower position that disengages from the nozzle head as shown in FIG.

  As shown in FIG. 1, the overcap E is made up of a top wall 36 and a side peripheral wall 37, and is fitted to the upper fitting portion 26 of the side peripheral wall 22 of the shoulder part C at the inner lower end of the side peripheral wall 37. A fitting portion 38 is provided.

Next, usage modes and operational effects of the liquid ejector of the present invention will be described.
In the ejection container A, in order to mix and use two liquids such as cosmetics and hair dyes, a required content liquid is stored in each container main body A1, and then a pump is attached to the container main body A1 by the mounting cap A2. It is attached to the mouth part 1.
Subsequently, the ejection head A is assembled by attaching the nozzle head A3 to the stem of the pump.

  Next, the support plate 24 of the presser plate D of the shoulder part C and the connecting portion 34 of the presser plate D are connected via the shaft pin 35.

  Next, each of the pair of ejection containers A is stored using the positioning member 13 of the case main body B, and the shoulder part C connected to the presser plate D is fitted thereon to form an outer case.

Finally, the overcap E is fitted, and the assembly of the liquid ejector is completed.
At that time, the bottom 3 of the container body A1 is positioned by the positioning member 13 of the case body B and placed on the bottom wall 12, and the guide tube 6 of the mounting cap A2 is attached to the top wall 21 of the shoulder part C. Each spout container A is fixed to the outer case because it is joined by the insertion port 23.

In use of the liquid ejector, when the overcap E is opened, a pair of ejection containers A in which both nozzle heads A3 are connected to the inner front side of the container by the pressing plate D are exposed.
Therefore, as shown in FIG. 4, when the presser plate D is pressed from above, both the nozzle heads A3 are pressed down between the upper end 33a and the lower end 33b of the bearing hole 33, and the two ejection nozzles are pressed. The content liquid is ejected from 9.
The ejected content liquid can be received by a tray, a palm, or the like in front of the ejection nozzle 9, mixed, and then applied to a required place.

Next, when only one liquid is selected and ejected, the presser plate D is rotated to the rear side of the container about the shaft pin 35 as shown in FIGS. Can be removed.
Therefore, when the desired nozzle head A3 is pushed down, the desired content liquid can be ejected from the ejection nozzle 9.
At that time, since the nozzle head A3 can rotate the direction of the ejection nozzle 9 on a horizontal plane, it can be changed to an arbitrary direction such as a side surface and a rear surface in addition to the front surface of the container.

  Finally, when the liquid dispensing container is closed, or when switching from the single liquid selective jet to the two liquid mixed jet, the jet nozzle 32 faces the front and the presser plate D is rotated upward, so that the protrusion 32 of the presser plate D is provided. However, it engages with the notch 10 of the nozzle head to change the direction of the ejection nozzle to a predetermined front direction as shown in FIG.

  Therefore, by rotating the presser plate D, it is possible to reliably switch between the two-liquid mixing jet and the one-liquid selective jet.

  In the above embodiment, specific shapes are shown for the cross-sectional shapes of the container main body, nozzle head, case main body, shoulder parts, etc., but quadrangular shapes with rounded corners, ellipses of various shapes, etc. can be adopted. The invention is not limited to the embodiment.

  In the embodiment, the outer case is composed of a case main body, shoulder parts, and an overcap. However, a pair of ejection containers are placed on a support base, and shoulder parts are attached to the shoulder part of the container main body or the mounting cap. The outer case is not limited to that of the embodiment.

  In the embodiment, the support plate of the shoulder parts and the connecting portion of the presser plate are pivotally mounted via the shaft pin, but the support protrusion is provided on the inner side of the support plates of the two shoulder parts. In the meantime, insert a long bearing hole in the connecting part of the presser plate and pivotably mount it, or place two long bearing holes in the two support plates and replace the shaft pin on both sides of the connecting part. A support protrusion may be provided, and the support protrusion may be fitted between the support plates so as to be pivotable. The connection between the support plate and the connecting portion is not limited to that of the embodiment.

  In the embodiment, the content liquid is ejected from the ejection nozzle. However, a spray nozzle may be attached to the nozzle head for spraying.

  Since the presser plate is attached to the shoulder parts so that it can be rotated, it can be connected to and disconnected from both nozzle heads, and the nozzle heads can be pressed and pressed down simultaneously. Liquid mixing and single-component selective jetting can be switched reliably, and the range of use of two-liquid mixing jets has been expanded, allowing it to be used not only in cosmetics but also in food and other fields.
