Description

  The present invention relates to a multiple aerosol ejector that simultaneously ejects different kinds of contents filled in at least two containers, and intends to improve the operability of the ejector.

  In recent years, in hair dyes, facial cleansing foams, treatments, and the like, products that use a liquid material mixed immediately before use as at least two kinds of contents having different compositions have been distributed.

  Such products are usually sold as a set in individual containers filled with each liquid, and when used, liquids are poured out of each container and mixed at a predetermined rate. There is a problem that it is not easy to use because it requires work to be performed.

  As a conventional technique for such a product, a foaming liquid mixing and discharging device is known in which contents are simultaneously poured out from each container in one operation (see, for example, Patent Document 1).

JP-A-4-10269

  By the way, containers filled with drugs such as hair dyes can simultaneously dispense the contents filled in each container at a predetermined ratio (usually 5: 5), and the dispensed contents. In the conventional mixing and discharging apparatus as disclosed in the above publication, it is accompanied by a lever operation when discharging the contents. Since the applicator moves along its axis, it may cause positional displacement, particularly when applied at the hairline or the like, and accurate application may not be possible.

  The subject of this invention exists in the place which proposes the multiple-type aerosol ejector excellent in the operativity which can perform the application | coating to a desired area | region correctly and simply simultaneously while pouring out the contents.

The present invention includes a joint that has at least two paths connected to an injection stem of an aerosol container, and combines different types of contents introduced through each path in a single path and discharges them from the tip portion of the joint. A multiple aerosol sprayer comprising a feeding path connected to the tip portion, and an applicator that jets the contents passed through the feeding path to the outer surface and holds it in a coatable manner,
A multiple cover comprising: a main body cover that is detachably fixed to the aerosol container; and an operation lever that is cantilevered on an inner wall surface of the main body cover and pushes the injection stem through a joint by its pulling operation. Type aerosol sprayer (corresponding to claim 1).

  The main body cover includes a socket that slidably fits and holds the tip portion of the joint and guides the contents discharged from the tip portion to the feeding path of the applicator (corresponding to claim 2).

The operating lever is supported by the inner wall surface of the main body cover so as to be able to swing, and the pressing portion is connected to the swinging end of the pressing portion and pulled toward the outer wall surface of the main body cover. It consists of the operation part to push down,
It is particularly preferable that the operation portion has a curved shape with a concave surface (corresponding to claim 3), and the applicator has a brush, comb, sponge or base having a base detachable from the holder of the main body cover. A nozzle or the like is applied (corresponding to claim 4).

  According to the present invention, it is possible to apply accurately while discharging the contents, and the operability is extremely good.

  Hereinafter, the present invention will be described more specifically with reference to the drawings. 1 to 4 show an embodiment of an ejector according to the present invention, in which the contents are ejected simultaneously from two containers, and FIG. 1 is a front view of the ejector (shown in cross section). 2 is a side view of FIG. 1 (shown in cross section), FIG. 3 is a cross-sectional view along AA in FIG. 1, and FIG. 4 is a cross-sectional view along BB in FIG.

  1-4, 1 and 2 are aerosol containers filled with different types of contents together with a pressurized medium. The aerosol containers 1 and 2 are integrally held by the ring C so that the contents can be ejected from the ejection stems 1a and 2a by pressing the ejection stems 1a and 2a. .

Reference numeral 3 denotes a joint. The joint 3 is shown as an example constituted by a base body having an opening that fits into the injection stems 1a and 2a of the containers 1 and 2 and an upper lid combined with the base body. Connected paths L ₁ and L ₂ and a single path L ₃ for joining the paths L ₁ and L ₂ are provided, and the contents introduced into the joint 3 through the paths L ₁ and L ₂ are transferred to the single path L. _{After being} merged or mixed at 3, the material is discharged from the tip portion 3a.

  4 is an applicator shown as an example of a brush, 5 is a body cover that is detachably fixed to the ring C at the upper part of the aerosol containers 1 and 2, and 6 is a pivot pin P on the inner wall surface of the body cover 5. This is an operating lever that is cantilevered at the starting point.

  The body cover 5 is integrally provided with a socket 5a that slidably fits and holds the tip 3a of the joint 3 and guides the contents discharged from the tip 3a to the feeding path 4a of the applicator 4. The operation lever 6 is cantilevered on the inner wall surface of the main body cover 5 and is supported in a cantilevered manner. The pressing portion 6a is in direct contact with the joint 3 and is connected to the oscillating end of the pressing portion 6a. It consists of an operation portion 6b that pushes down the pressing portion 6a by operation (the white arrow in the figure).

  When the aerosol containers 1 and 2 are gripped and the operation portion 6b of the operation lever 6 is pulled with a fingertip as shown in FIG. 5, the pressing portion 6a descends from the pivot pin P as a starting point and the nozzle body 3 is pushed in ( At the same time, the spray stems 1a and 2a of the aerosol containers 1 and 2 are also pushed down.

When the injection stems 1a and 2a are pushed down, the contents in the containers 1 and 2 are ejected from the tips of the injection stems 1a and 2a, and the paths L ₁ and L ₂ , the single path L ₃ , and the feeding are shown according to the arrows in the figure. It will be discharged | emitted to the outer surface of the applicator 4 through the path | route 4a and the opening 4b, and discharge | emission of the contents will continue as long as the operation lever 6 continues to be attracted.

  On the other hand, when the attraction of the operation lever 6 is released, the nozzle body 3 and the pressing portion 6a are returned to their initial positions by the reaction force of the elastic members originally provided in the injection stems 1a and 2a, and the discharge of the contents is immediately stopped.

  The ejector according to the present invention can easily discharge the contents to the applicator by simply pulling the operation lever 6 with the fingertip and releasing the attraction as described above, and the applicator 4 is easy to operate. Regardless of the attraction of the lever 6, the position is always constant, so that accurate application is possible.

  The operation portion 6b of the operation lever 6 is provided with a curved recess d so that the finger can be easily caught and the nozzle body 3 can be pushed in with a slight pulling operation.

  FIGS. 6 and 7 show the applicator 4 as an example of a nozzle. By mounting such a nozzle as the applicator 4, the contents can be applied at a pinpoint. However, the discharging procedure of the contents is not different from that of the ejector shown in FIGS.

  An O-ring 7 can be provided between the tip 3a of the joint 3 and the socket 5a in order to maintain a liquid-tight state.

In the embodiment of the present invention for pressing portion 6a of the operating lever 6, it is shown for the case of contact with the joint 3 the convex portion 6a ₁ of the inverted triangle at two opposing positions, the joint 3 by attraction of the operation portions 6b The shape is not particularly limited as long as it can be pushed in.

  The main body cover 5 is fixed and held by the ring C. However, the main body cover 5 may be directly installed on both the containers 1 and 2, and this point is not particularly limited.

The joint 3, even when the partition plate is provided therein so as to isolate the although not illustrated path L ₁ and path L ₂ a single path L _3, thereby so as to discharge the content in a layer state it may, also, may be forcibly mix the contents passing through the path L _1, L ₂ established a screw member into a single path L ₃ in a single path L _3.

  A multiple aerosol sprayer with good operability can be provided.
