Claims. (Cl. 15-134) This invention relates to dispensers,.and more particularly to dispensers for liquids, for example deodorants, perfumes, liquid lipsticks, liquid rouge, lotions or the like.

When hitherto customary dispensers are used for applying liquid to a portion of the body of a person it is necessary to hold the outlet of the case of the dispenser downwardly or else to pour the liquid rst on the palm of a hand and then apply it to the body. This kind of dispenser is especially inconvenient for applying the liquid to the armpit, even if the dispenser is in the shape of a sprayer. t

An object of the invention is to provide a dispenserv for a liquid, by means of which the liquid may be readily applied to any portion of the body.

Another object of the invention is to provide ka dis# penser for liquids which may be readily used in any position. f

A further object of the invention is to provide a dispenser by means of which a controlled amount of the liquid may be applied to the body foreach application, so as to avoid the disadvantage of hitherto customary dispensers which discharge too great an amount of liquid to relatively small surfaces of the body.

Still another object of the 'invention 'is to provide a dispenser which is perfectly sealed so as to prevent the escape of liquid while the dispenser is not used.

A further object of the invention is to provide a dispenser for liquids which overcomes the disadvantages of hitherto known dispensers for liquids and yet may be manufactured at low costs.k K

Other objects and structural details of the invention will be apparent from the following description when read in conjunction with the accompanying drawings forming part of this specification, wherein:

Fig. 1 is a vertical sectional view of a'dispenser for liquids according to the invention,

Fig. 2 is a sectional view takenalong line Il-II of Fig. 1,

Fig. 3 is a sectional view of the upper portion of the dispenser shown in Fig. 1, wherein however the closing cap is removed and the applyingmembrane is vin' the position which it occupies during the applying of the liquid to the body, and

Fig. 4 is a vertical sectional view of another embodiment of the upper portion of the dispenser according to the invention.

Referring now to Figs. 1 and 2, 10 generally indicates a dispenser for liquids comprising a container 12 having a threaded neck portion 14.

A hollow member, generally indicated by 16, tightly inserted into the bore of the neck 14 comprises a bottom 18, a cylindrical wall 20, four inwardly projecting elements 22 and an annular top element 24. The elements 22 are shorter than the cylindrical wall 20, so that a chamber 26 is formed inside the member 16 between the upper end of the elements 22 and the lower surface ICC of the annular top element 24. Said chmaber 26 communicates with the interior of the container or case 12 through bores 28 extending through the elements 22.

A cylindrical body 30 inserted into the cavity of the member 20 is held therein by means of the protruding elements 22. Said body 30 is made of an elastic porous mass, preferably of a foam material and acts as a porous reservoir member. It has been found that excellent results are obtained by means of a foam material made of a material known in the trade under the trade-name Neoprene A membrane 32 engaged with a slot 34 of the top element 24 of the member 20 is likewise made of an elastic porous material, preferably a foam material made of so-called Neoprene The inner edge 36 of the top element 24 is somewhat higher than the upper surface of the body or porous reservoir member 30, whereby a space 38 is formed between the body 30 and the menibrane 32.

A threaded cap may be screwed on the threaded neck 14 of the case 12 for closing the aperture thereof.

The dispenser may be used as follows:

The container 12 is lled with a liquid, for example deodorant, perfume, liquid lipstick, liquid rouge, lotion. When the dispenser is carried around, vfor example in a pocketbook, owing to the shaking of the pocketbook liquid ows from the interior of the container 12 through the bores 28 into the chamber 26 of the member 20 and thence into the porous body or porous reservoir member 3d. Thus the body 30 absorbs a certain amount of the liquid. lf the dispenser should not have been carried around in a pocket book, the same effect may be obtained by manually shaking the dispenser before use.

Now when after removal of the cap 40 the dispenser is used and its porous membrane 32 is pressed against the skin of the body, said membrane 32 obtains the concave shape as shown in Fig. 3. Thereby the porous membrane 32 comes into contact with the upper surface of the porous reservoir body 30, so that a controlled or predetermined amount of liquid contained therein is pressed through the porous membrane 32 onto the outer surface of the latter for application to the skin.

The amount of liquid to be applied to the skin can be readily regulated by pressure exerted during the application of the liquid. The higher the pressure, the more liquid will be applied to the skin. The desired pressure can be predetermined by choosing a certain distance between the body 30 and the membrane 32 and/ or by selecting a certain thickness of the membrane 32. Furthermore the density of the foam material of the body 30 and/ or the membrane 32 will have a controlling influence on the amount of liquid to be applied to the skin during each application. l

It will be readily understood from above, that the dispenser according to the invention eliminates the discharge of uncontrolled amounts of liquidsduring the application and that such a suppression of the discharge of kuncontrolled amounts could not be obtained if the body 30 lled with liquid would be applied directly to the body -of a person.

Furthermore the outlet of the dispenser according to the invention is tightly sealed when not in use. The space 38 left between the membrane 32 and body or porous reservoir member30, normally filled with air, prevents an escape of the liquid absorbed by the body 30 from the latter.

The embodiment shown in Fig. 4 is similar to the embodiment shown in Fig. 3. However the porous membrane 32 of the dispenser of Fig. 3 is replaced by a member 248 made of an elastic but non-porous material. Said member or membrane 248 being provided with a series of a'person, it is bent inwardly 4for engagement with the wet body 230, from which a predetermined amount of liquid is pressed through the bores 250io`f kvthe membrane 248 onto' the skin of the person. The 'amount of to be applied to the skin during an application can be pre.

determined by choosing a certain "number Vof holes of certain size in the member 24S. I have described preferred embodiments of-my invention, but it is understood that -this disclosure is forthe;

purpose of illustration and that various omissions or changes in'shape, proportion andarrangement of parts,

Vas well as the substitutiony vof equivalent elements for those herein shown and ydescribed may be made without departing fro-m the spirit and scopeof the invention as set' forthin the appended claims.
