Description
1 ~62~64 NOVEI, IIIQUID DEIiIVEP~Y S:YSTEM FC~R TOII.ETRIES
The present ;nvention relates to a liquid applica-tor for dispensing toiletries to the skin, and particularly for the applicat;on of antipersp;rants and deodorants to the human axilla.
Liquïd appl;cators i~ general are well-known in the prior art, particularly the roll-on type commonly for antiperspirants and deodorants. These are disclosed, for example, in U. S. Patents 2,749,5~6; 2,923,957; and 2,998,616.
Because of pro~lems wit~ roll-~n type applicators, 3erghahn et al., U. S. Patents 4,050,826 and 4,111,567, devised a liq-uid applicator comprising a container fitted with a head having a fixed, s~aped form made of a non-flexible, non-de-formable, sintered porous synthetic plastic resin having a controlled ~orosity and fiaving omni-directional, interconnect-ing pores. The liqufd overflow problems associated with con-ventional roll-ons is also present with this type of head and is solved by the pro~ision o~ a liquid collecting channel adjacent the shaped applicator, permitting the excess liquid to drain back via the channel into an opening through the head into the liquid reservoir. This avoids an accumula~ion of liquid on the surfac~ of the applicator and resulting crystallization of product being delivered.
The porous plastic applicator of Berghahn et al.
resembles the conventional roll-on applicator except that it is stationary and has a drain channel. The liquid product being delivered must be brought into contact with the a cator head in order for the liquid to be delivered to the surface by capillary action. This requires irverting the 1 162~
container, resulting in leakage of material in the inverted position.
According to the invention there is provided a liquid applicator suitable for use in the application of liquids to a surface of the human body comprising a shaped container adapted for storing a quantity of said liquid/ said container having an opening at the upper end thereof, shaped applicator means posi-tioned in said opening, sai.d applicator means comprising a non-flexible, non-deformable, sintered, porous synthetic resin struc-ture having a controlled porosity and having omni-directional interconnecting pores, and means to create pressure on the liquid within said container.
In the present invention, the applicator head may be of any suitable configuration, but a convex outer surface has been found to be particularly suitable for contact with various parts of the human body. Thus, the applicator head may have a hemi-spherical shape, either soli.d or hollow.
~ 2 --1 1621~4 The materials which a~e used to make the shaped ap-plicator head are non-flexible, non-deformable, sintered, porous synthetic resins having a controlled porosity and having omni-directional interconnecting pores, formed of ag-gregates of united polymer particles. The degree of porosity of the porous materials can be controlled in their manufac-ture, thus insuring a wide range of porosity to suit a wide range of liquid products of varying viscosities. Sintered, porous applicator heads may ~e fabricated of high density polyethylene, low-density polyethylene, ultra-high molecular weight polyethylene, polypropylene, polyvinylidene fluoride, and the like. Products are'avaîla~le commercially under the trade designations '~orex" porous plastic~ and "Porous Pol~."
The ~ore size of the applicator may ~ary widely, depending on the liquid to be'del'iverea. ~ow-viscosity liquids, such as perfumes, may best ~e del;vered via a small-pore plastic applicator, e.g., one micron or less. In general, the pore size may vary betwe~n a~out one'to 200 m~crons, and for most purposes, generally a~out la-50 microns are preferred.
The porous applicator head fits into an annular plas-tic ring which in turn fits into the top opening of the con-tainer. The plastic ring also holds an inner flexible bag which forms a reservoir for the liquid Illaterial to be dis-pensed. The container has an air vent to maintain atmos-pheric pressuxe within the container and outside the flexi-ble bag. Thus as liquid is withdrawn from the reservoir, the pressure of air entering compresses the flexible bag to conform substantially to the volume of the contents. This aspect of the invention insures continuous contact of the liquid with the applicator head and ease of delivery of the liquid on demand by capillary flow. The flexible bag may be of any suitable material, e.g.,polyethylene, polypropyl-ene,~r, or the like.
It will also be obvious that the reservoir could be a shaped plastic cylinder having annular pleats allowing it to collapse under pressure.
The container may obviously be of any suitable material, such as metal, glass, or plastlc.

The delivery system of the invention may be used to deliver any topical liquid product to the skin. Ihese may include, for example, after-shave lotions, pre-shave lotions, skin lubricants or emollients, suntan lotions, fragrances (perfumes, colognes, etc.), topical therapeutics (analgesics, acne formulations, antiseptics, etc.), lip and face rouge and the like. The delivery system is particularly useful in applying antiperspirants and deodorants and avoids the problems associated with roll-on applicators. Thus, the invention provides a means of applying a low viscosity, fast drying, non-sticky solution of aluminum chlorhydrate, avoiding the undesirable features of roll-ons, pump sprays, and sticks.
Since the porous plastic materials are hydrophobic and do not "wet"
with water, it may be necessary to add alcohol to an antiperspirant formula to transfer the product from the container to the applicator head. Crystallization of the solid components of the solution, such as aluminum chlorhydrate, may be avoided by the addition of certain esters, such as isoyropyl myristate or iso-propyl palmitate.
The invention may be better understood by reference to the drawings in which, Figure 1 is a perspective view of the liquid delivery system with the cap of the package removed to show the hemispherical applicator head;

Referring to Figures 1 to 5, the liquid delivery system comprises an outer case 10 having a base 12 and a cap 14 which is attached by means of threads 16 at the top of case 10. It will be understood that cap 14 could be attached by a friction fit also. A porous plastic applicator head 20 is fitted into an annular plastic ring 25 through central opening 26 of ring 25. Applica-tor head 20 has an inner cylindrical portion 21 which fits into opening 26 and is held by friction fit in annular ridge 22 on the inner surface of ring 25. Flex-ible plastic bag 18 is held between ring 25 and the inner surface 24 of contain-er 10 at the neck area 27 and forms a fluid tight friction fit to contain liquid product 28 in bag 18. A vent hole 30 is provided in base 12 of container 10 for entry of atmospheric air between the inner surface of container lO and the outer surface of bag 18. The product 28 is delivered to the surface of head 20 when the head is rubbed against the skin and as the volume of product de-creases, air entering hole 30 will collapse flexible bag 18 to conform to ~he volume of remaining liquid 28 and thus assure even flow through porous head 20.
Thus, atmospheric pressure aids in forcing the liquid through head 20, thereby 1 1621~
supplementing the capillary flow and assuring an adequate flow of liquid product 28 to the outer surface of head 20.
Referring to Figures 6 to 9, the liquid delivery system comprises an outer case lO open at the top, having a base 12 and a cap 14 which is attached by means of threads 16 on neck 18 at the top of case 10. It will be understood that cap 14 could be attached by a friction fit also. Case 10 contains the liquid product 20 to be dispensed. A porous plastic application head 22 is fit-ted into the open end 24 of case 10. In the embodiment shown in the Figures, the applicator head 22 has a hemispherical outer surface 26 and is hollow in-side, and fits by friction into neck 18 of case 10. The applicator head 22 may also be a solid hemispherical element. Applicator head 22 may be saturated with the liquid product 20 by pressure on the walls of case 10, but no liquid flows through head 22 by simple inversion of the device. This provides for positive control by the user, and avoids leakage and dripping of liquid.
Referring to the Figures 10, 12 and 13, the liquid del;very system com-prises an outer case 10 open at the top and in base area 12. A cap 14 is at-tached by means of threads 16 at the top of case 10. It will be understood that cap 14 could be attached by a friction fit also. Case 10 contains the liquid product 16 to be dispensed. A porous plastic applicator head 20 is fitted into the top opening of case 10. Applicator head 20 has a cylindrical portion 21 which extends into case 10. As shown in Figures 2 and 3 the porous head 20, may be held in place by a retaining ring 36. As shown the cylindrical extension 21 is long enough to reach substantially to the base of container, but this could be shorter so long as it fits within the top of container 10. The applicator head is inserted into container 10 by friction fit and forms a fluid tight fric-tion fit in container 10.
Base 12 of case 10 is closed with a flexible diaphragm structure 22 which consists of a diaphragm 24 and retaining ring 26 resting against flange 18 of base 12. In the embodiment of Figure ~, the diaphragm structure 22 also includes a baffle 28 having an opening 30 and a conical structure 32 for main-taining a curvature in diaphragm 24. When diaphragm 24 is pressed for example to the position shown by broken line 34, a pressure is created within case 10 which expels the liquid contents 28 through the pores of porous head 20, supple-menting the capillary flow and assuring an adequate flow of liquid product 38 to the outer surface of head 20. Thus the liquid does not flow through head 20 when the case is inverted, but only when pressure is applied to diaphragm 24.
This allows positive control of liquid flow by the user.
In the embodiment shown in Figure 11, case 10 has a closed base 12 a flexible bulb like area 40 on the side of the case. This may be formed by making the case thinner in this area. ~hen bulb 40 is pressed inwardly to the position shown by broken lines 42~ an internal pressure is formed, expeling product through head 20, as described above.
The diaphragm 24 may be formed of any suitable, flexible material e.g.
rubber or plastic, so long as a fluid tight closure is formed Eor the bottom of case 10.
It will be obvious that other variations of the invention may be made.
For example, flexible plastic bag could be a plastic cylinder having annular pleats to allow collayse under pressure.
A variety of liquid products may be dispensed by means of the invention.

The delivery system of the invention may be used to deliver any topical liquid product to the skin. Ihese may include, for example, after-shave lotions, pre-shave lotions, skin lubricants or emollients, suntan lotions, fragrances (perfumes, colognes, etc.), topical therapeutics (analgesics, acne formulations, antiseptics, etc.), lip and face rouge and the like.

When diaphragm 24 is pressed for example to the position shown by broken line 34, a pressure is created within case 10 which expels the liquid contents 28 through the pores of porous head 20, supple-menting the capillary flow and assuring an adequate flow of liquid product 38 to the outer surface of head 20. Thus the liquid does not flow through head 20 when the case is inverted, but only when pressure is applied to diaphragm 24.
This allows positive control of liquid flow by the user.
In the embodiment shown in Figure 11, case 10 has a closed base 12 a flexible bulb like area 40 on the side of the case. This may be formed by making the case thinner in this area. ~hen bulb 40 is pressed inwardly to the position shown by broken lines 42~ an internal pressure is formed, expeling product through head 20, as described above.
The diaphragm 24 may be formed of any suitable, flexible material e.g.
rubber or plastic, so long as a fluid tight closure is formed Eor the bottom of case 10.
It will be obvious that other variations of the invention may be made.
For example, flexible plastic bag could be a plastic cylinder having annular pleats to allow collayse under pressure.
A variety of liquid products may be dispensed by means of the invention.
Illustrative products are set forth in the following specific Examples.
