Abstract

PROBLEM TO BE SOLVED: To easily distribute liquid matter to desired positions by a method wherein a distribution nozzle is equipped with a distribution head and a plurality of nozzles that are combined with the distribution head. SOLUTION: A distribution nozzle 1 used for instance for distributing hairwash is composed of a hollow distribution head 2 and a series of hollow nozzles 3 each extending approximately at a right angle from the distribution head and accessible from the distribution head 2. An attachment member 4 for attaching to a liquid matter container is formed at one end of the distribution head 2. The attachment member in this instance is a screw cap with internal thread provided at the inside thereof. Liquid dye is put in a container that is closed with the screw cap, and the liquid dye is made to flow into the nozzle members from the inside of the container with the pressure of the container. The number of nozzles 3 can be variable, ranging from 4 or 5 to 10 or 12. Especially, 8 is a number desirable for nozzles for dyeing.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a dispensing nozzle,
In particular, it relates to a nozzle for dispensing creams and other liquids, preferably viscous liquids.

[0002]

BACKGROUND OF THE INVENTION There are several applications where creams and other liquids need to be delivered to relatively precise locations. One such application is hair coloring, which must be supplied essentially at or near the root of the hair. Usually, dispensing containers used for liquids such as hair dye have a single nozzle.
And the operation of applying over the hair to ensure that the hair dye is evenly distributed is relatively laborious.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a dispensing nozzle capable of distributing liquids to desired portions more easily.

[0004]

SUMMARY OF THE INVENTION The present invention, in its broadest sense, is adapted for connection to a liquid container and has a dispensing head, the dispensing head having a plurality of nozzles associated therewith. Including a dispensing nozzle.

[0005] The nozzles are preferably located next to each other, and they are either along a line or have a certain curve so that they can more easily follow the surface to which liquid is to be supplied. Are preferably arranged along.

[0006]

DETAILED DESCRIPTION OF THE INVENTION In order that the present invention may be more readily understood, certain specific embodiments made in accordance with the present invention will be described.

Although the material of the nozzle does not form part of the present invention, the nozzle may be an injection molded plastic material. And preferably applied to connecting to the neck of the bottle containing the substance to be dispensed,
It has an inlet with an internally threaded groove.

Here, a case where the nozzle is used for dispensing the hair dye will be described. However, it should be understood that it can be used in other applications, such as, for example, to provide a conditioner or shampoo near the root of the hair, as well as in applications where the liquid is applied throughout the subject.

[0009] Connected to the inlet, a plenum
Etc. may be present. The plenum extends symmetrically on each side of the inlet section and is connected to the inlet section and through which the contents of the container to which the nozzle is to be connected are communicated. A plurality of supply nozzles extend outwardly from the plenum. Each of these nozzles is preferably of the same length and is equally spaced along its plenum, with a spacing of 2 to 10
mm, preferably the centers are separated by about 5 mm. This interval is chosen depending on the viscosity of the liquid to be dispensed and the required supply.

[0010] The number of nozzles can vary from four or five to ten or twelve. Especially,
The inventor has found that eight nozzles are a desirable number for dyeing.

[0011] The plenum itself can be straight,
That is, the center of each nozzle is 1 in the vertical plane passing through the plenum.
The plenum may be curved along one straight line, or the plenum may be curved such that each nozzle is arranged around an arc. This arrangement can be the most satisfactory arrangement for use on the scalp, which can be generally considered spherical. Here, the arc can cause the nozzles to move over each portion of the scalp, with each nozzle in direct contact with the scalp. In any case, a use is provided in which a nozzle is attached to a staining solution container in use.

Although one or more caps may be provided to cover individual supply nozzles, it is preferred to provide the nozzles separately from the container.

[0013] A nozzle is provided which can be inserted into a receiving member in a cap member for covering the staining liquid container. At this time, an opening is formed in the cap by inserting the nozzle into the cab member. It is also preferred that the dye liquid be sent to the nozzle through the opening.

The material to be dispensed is then supplied to the scalp by contacting the dispensing nozzle with the scalp and applying pressure to the container to pump liquid through different dispensing openings across the width of each dispensing nozzle. Is done.
And in that way substantially the entire area of the scalp can be covered in a single pass of the application device, with the dye being directed directly to the hairline and thereby to the desired site. This operation need only be repeated over the entire area to provide a good supply of dye.

The inventor has found that this operation is much quicker and easier than using a conventional single nozzle.

BRIEF DESCRIPTION OF THE DRAWINGS To aid the understanding of the present invention, reference is made to the accompanying drawings, which illustrate two embodiments of the present invention.

With reference to FIGS. 1 and 2, the first
Comprises a hollow dispensing head 2 and a series of hollow nozzles 3 extending therefrom at approximately a right angle (greater or less than a right angle) and readily accessible from the dispensing head. At one end of this dispensing head,
There is an attachment 4 to the liquid container. In this example, the mounting means is a screw cap having a thread groove on the inside.

With reference to FIGS. 3 to 5, a second embodiment of the dispensing nozzle 1 comprises a hollow dispensing head 2 and extending therefrom at approximately a right angle (above or below a right angle).
It has a series of hollow nozzles 3 which are immediately accessible along zero. The inlet tube 10 has a sloped inlet 1 which helps to remove the closure member 23 at the base of the receiver 22 which is inside the member 21 above the cap 20.
2

In this embodiment of the present invention, the dye solution is contained in a container closed by a cap 20, which is partially provided at the base of the receiving portion 22. Has a member 23 cut out. The inlet tube 10 can be inserted therein until the tip 24 of the member 21 abuts the shoulder 11 of the inlet tube. By this step, the inlet tube 10 pushes the member 23 into the container, and the pressure in the container allows the dye liquid to flow out of the container and into the nozzle member.

Although the present invention has been described in terms of two specific embodiments, it should be understood that various changes or modifications thereof may be made without departing from the scope of the invention.
