Description

An applicator housing of an antiperspirant material

  active from a liquid base. The invention relates more particularly to housings of this type, in which the applicator element is of the capillary type. Applicator housings intended for the application of liquids and using a fixed applicator element have been known for a long time. U.S. Patent No. 1,586,044 describes a device of this type which uses a felt pad as an applicator element in a housing designed to dispense liquid makeup. U.S. Patent No. 2,726,416 discloses a liquid applicator for dispensing a spectacle lens cleaning liquid, which device also utilizes a dispensing element consisting of a "firm" or "hard" felt. Applicators of the "dab-o-matic" type have also been suggested for dispensing liquid antiperspirant compositions, and include sponge-like applicators which are unsatisfactory in many respects. Firstly, these housings are inclined, which causes too free flow or evacuation and prevents a clean application of the material.Then, during use, the pores of these applicators tend to be blocked by skin debris collected when the applicator is used for the armpits, which interferes with the flow of antiperspirant fluid through the applicator and the accumulation of skin debris in the applicator. kills a source of unhygienic material that can putrefy by producing bad odors.

  It appeared that the disadvantages listed below

  above can be eliminated by using, in the applicator housing described above, an applicator element comprising a fibrous body consisting of continuous filament strands whose filaments are oriented in a longitudinal direction or in a horizontal direction or in a random manner but mainly in a longitudinal or horizontal direction, such an applicator being hereinafter referred to as the "capillary applicator". Materials of this type are described in U.S. Patent No. 3,111,702. As described in the aforementioned patent, applicators prepared by the described method mainly comprise a randomly oriented continuous filament body. but mainly in a longitudinal direction. The fibers of this body are bonded to adjacent fibers and the peripheral layer of fibers is stiffened to form an outer shell or skin for the body. The method makes it possible to obtain a cell body which constitutes an applicator which can contain a liquid in its cellular structure and from which the liquid can be dispensed by the application, under a low pressure, of this applicator, loaded with liquid,

on a surface.

  To produce a capillary applicator of the type described above, in which the fibers are oriented in a horizontal direction, or are oriented randomly, but mainly in a horizontal direction, the body consisting of bonded filaments and comprising the envelope or outer skin as prepared by the process described in the aforementioned US Pat. No. 3,111,702, is cut transversely and approximately perpendicular to the longitudinal orientation of the fibers to obtain segments having two surfaces. cut and a body covered with an envelope or skin. When these segments are introduced into the container, they are arranged so that the cutting surfaces bear against opposite faces of the inner and vertical surface of the container. The other surfaces of the capillary applicator, including the surface used for the application of the material contained in the container on the subject, are substantially covered by the skin- or

envelope.

  When attempting to adapt a capillary applicator of the type described above for dispensing liquid antiperspirant compositions, there is

2 483756

  many problems. It has been found, for example, that when a hair applicator made of cellulose acetate fibers is used to dispense certain alcoholic, aqueous or aqueous-alcoholic compositions containing certain aluminum antiperspirant salts, the capillary applicator decays at the same time. after a short period of time. it has also been found that if the element is too dense, it is not possible to load the capillary applicator with a sufficient quantity of antiperspirant fluid to make a practical casing. In addition, when the capillary applicator has certain densities, although it is possible to load antiperspirant liquid, it is not possible to bring out the liquid of the applicator. In addition, at certain densities, the capillary applicator can not retain the liquid

  antiperspirant leaking from this applicator.

  In addition, since it is necessary to dispense an effective dose of antiperspirant in a reasonable number of movements in the armpit region, this raises a particular problem. It has been established that an effective dose of antiperspirant salts is between 150 mg and 150 mg. A reasonable number of strokes to apply such a dose to the region of an armpit is about 10 movements. In addition, it is important to be able to dispense the antiperspirant material at a uniform rate. Applicators of various densities have failed to dispense the necessary dosage of antiperspirant in a reasonable number of strokes, or to dispense this

matter at a uniform flow rate.

  It turned out that all the problems listed below

  can be removed if the capillary applicator is made of a material which is stable towards the antiperspirant material contained in the container and if. the capillary applicator has a specific gravity of between 0.122 and

3 3

  0.244 g / cm 2, and preferably between 0.152 and 0.183 g / cm. Any leakage or leakage of the antiperspirant fluid is avoided by the use of the capillary appliques elements according to the invention. This is due at least in part to the fact that the liquid product is completely absorbed and retained in the capillary applicator element and can be dispensed without the need to place a liquid reservoir in the container. It therefore appears that, although the element is described as being a capillary applicator, it assumes both the function of an antiperspirant storage element and that of a

applicator element.

  For the specific weights of the capillary applicator indicated above, namely 0.122 to 0.244 g / cm 3, and preferably 0.152 to 0.183 g / cm 3, it is possible to dispense an effective dose of antiperspirant in a reasonable number of movements. performed on the armpit of the subject and at a uniform flow rate. It is therefore possible to deposit about 40 to 150 mg of active antiperspirant material on the armpit of a subject with a maximum number of strokes when the applicator housing according to the invention is used. This is very important to achieve a housing intended to be a practical way to prevent

effectively perspiration.

  Since the active antiperspirant is applied at a uniform rate by means of the applicator according to the invention, the antiperspirant effect can be easily obtained repeatedly. As soon as the user has determined the dose that is effective, ie the number of strokes required to apply an effective amount of antiperspirant, he can repeat this operation.

  whenever he needs to use the applicator.

  As indicated above for a feature of the invention, the capillary applicator used is of the type comprising fibers oriented in a horizontal direction or oriented randomly, but mainly in a horizontal direction. This has several distinct advantages. First, this feature is advantageous for the formation of a normal skin or skin inherent in the manufacture of the related applicator devices. The cutting tips of the application devices, produced during manufacture, tend to be rough and irritate the skin of

  the user if they were applied against it.

  However, when the bonded segment is introduced into the casing and positioned so that the filaments have a horizontal position or are randomly oriented, but mainly in a horizontal direction, the skin or natural envelope, which is smooth as a result of the process used , covers the part of the applicator to enter

  contact with the skin of the user.

  Secondly, when the hair applicator used is of the type. introduced into the container so that the fibers are oriented in a longitudinal direction or randomly oriented, but mainly in a longitudinal direction, a cut end of the applicator is arranged to serve as a surface to be applied against the skin . Since this surface tends to be rough, the practice is to melt it under the effect of heat, to a certain extent, to remove roughness. However, this operation is carried out at the cost of the uniformity of the flow of the product of the container. It has been found that when the capillary applicator is disposed in the container so that the fibers are oriented in a horizontal direction or are oriented randomly, but mainly in a horizontal direction, and that the skin or envelope normally produced covers the surface of the applicator to be applied against the skin of the subject, as previously described,

  uniformity of flow is significantly improved.

  Alcoholic or aqueous support systems for the active antiperspirant are preferred. However, this raises other issues. Since the alcohol of these vehicles is volatile, to prevent the loss of alcohol or water and the resulting crystallization of the active antiperspirant material, it is necessary to provide a suitable sealing device. For the same reason, in order to avoid an excessive rise in the pressure of the alcohol vapors, means must be provided to eliminate this pressure. The device

  according to the invention is designed to solve these problems.

  The invention will be described in more detail with reference to the accompanying drawings by way of non-limiting examples and in which: FIG. 1 is a perspective view of the applicator housing according to the invention, represented in the closed position; Fig. 2 is an exploded perspective view of the applicator housing of Fig. 1 which has been turned over and is open for use; Fig. 3 is a vertical section on line 3-3 of Fig. 1; Figure 4 is a section on line 4-4 of Figure 3; Figure 5 is a section on the line 5-5 of Figure 3; Figure 6 is a partial, vertical and enlarged cross-sectional view of the housing of Figure 1 showing the two halves of the device in the closed position; Figure 7 is a partial section similar to that of Figure 6 showing the two halves of the device in the separated state; Figure 8 is a perspective view, similar to that of Figure 1, showing the container sealed by a ribbon; Figure 9 is a partial cross-section, on an enlarged scale, similar to that of Figure 6, of another embodiment of the invention, showing the two halves of the device in the closed position; and FIG. 10 is a partial cross-section, vertical and on an enlarged scale, similar to that of FIG. 6, showing another embodiment of the invention, and more particularly the opposite side of the

  device considered in vertical section.

  FIG. 1 represents the applicator housing according to the invention, bearing the overall numerical reference 1 and comprising an upper part 3 forming a body and a lower closing part 5. This part 5 comprises a base 7 which allows the housing to hold of itself in the inverted position. A capillary applicator 9 is shown in FIG. 2 in the operating position and is held by the body 3 in a manner described in more detail below. In the embodiment shown, the body 3 is in the form of a parallelepiped

  rectangle whose angles are rounded.

  The body 3 is hollow and has several vertical ribs 11 ven'tilation that extend over the entire length of its inner surface. In the variant shown in FIG. 4, four groups of vertical ribs are provided, each rib projecting inwards, in the cavity of the body 3. The latter also comprises two horizontal bars 13 which are situated at about two-thirds of the body length 3, from the bottom of the latter. These bars are fixed and they are preferably made in one piece with the inner surface of the body 3 so as to protrude into the

cavity of the latter.

  The horizontal bars 13 serve as locking elements which hold the capillary applicator 9 inside the body 3. after the liquid has been introduced into the body 3 and the capillary applicator 9 has been inserted into the latter, the applicator absorbs practically all the liquid and swells. Therefore, the horizontal bars 13 end up being locked inside the

  body of the applicator and fix it in position.

  The ribs 11 assume several functions.

  Their main function is a ventilation function.

  The latter may come into play during the use of the applicator. When the antiperspirant is applied, there remain gaps inside the applicator which must be filled with air so that the applicator can continue dispensing liquid. Part of this aLr arrives through the pores of the applicator element that is designed for this purpose. However, a significant amount of air also enters the interior of the body 3 while passing

  between the ventilation ribs 11.

  In a substantially similar way, the

  11 ventilation ribs delimit escape channels.

  for the excessive pressure which can accumulate inside the body 3 under the effect of evaporation of some of the low boiling materials present in the composition. These ribs direct the pressure towards a pressure elimination device described

in more detail below.

  Another function of the ventilation ribs 11 appears during the filling operation. During filling, as described in more detail below, the liquid antiperspirant is first placed in the body 3, then the capillary applicator 9 is introduced into the body. In this case, the ventilation ribs assume the function of a conduit allowing the flow of the excess of antiperspirant liquid discharged from the body 3 during

  the introduction of the capillary applicator element 9.

  Another function of the ventilation ribs 11 relates to the manufacture of the body 3. To allow a convenient application, it is desirable that the body 3 has an oval internal configuration in order to be associated with a capillary applicator 9 of oval shape. However, at the same time, the outer shape of the body 3 must be rectangular, in cross section. This is made possible by the ventilation ribs 11 which reduce the mass of

  matter located within the corners of the body 3.

  A shoulder 15 is cut in the outer surface of the body 3, near its outer and lower edge. This shoulder extends around the circumference of the body 3 and constitutes a seat for a ring 17 which, as best shown in FIG. 5 which is detailed, has, in cross-section, a substantially circular shape in the uncompressed state. . When the ring is compressed by the closing part 5 or hood, as described in more detail below, it is deformed and ensures

  the seal between the inside of the container and the atmosphere.

  The ring 17 may be made of any of a variety of compressible materials. However, it has emerged that the best results are achieved

  when one makes the rubber ring of the type "Buna-N".

  A discontinuous rib 21 is located at about half the distance measured downward from the shoulder 15 on a vertical wing 19. In the embodiment shown, the rib 21 is divided into four sections, two of which are disposed on the sides of the body 3, the two other sections being located, one on the front surface and the other on the rear surface of the vertical wing 19 of the body 3. The rib 21 has a vertical surface 23, a an upper oblique surface 25 which is inclined upwards and inwards, and a lower oblique surface 27 which is inclined downwards and inwards. The rib 21 is designed to assume two functions, the first of which is engagement with a corresponding rib formed on the cover 5 when the latter is resiliently engaged in position, so as to constitute a locking mechanism. The second function is the formation of a ventilation device, as described

in more detail below.

  The cover 5 has a skirt 29 which protrudes upwards. A flexible mechanical seal 31 protrudes inwardly of this skirt so as to bear against the lower edge of the body 3 when the elements are assembled. A discontinuous rib 33, similar to the discontinuous rib 21 of the body 3, is formed on the skirt 29. This rib has a vertical surface 35, an upper oblique surface 37 which is inclined downwardly and inwardly, and a surface lower oblique 39 which is inclined upwards and inwards. However, in the case of rib 33, the latter is turned

  internally to the center of the hood cavity 5.

  In use, a certain amount of a liquid antiperspirant composition, described in more detail below, is loaded into the body 3. The capillary applicator 9 is then introduced into the body 3 so as to be able to absorb the entire liquid. The cover 5 is then placed on the body 3 until the lower edge

  of the latter door against the mechanical seal 31 of the cover 5.

  In this position, the rib 21 of the body 3 is resiliently engaged on the rib 33 of the cover 5 and the upper edge of the cover 5 bears against the ring 17 that it compresses. Simultaneously, the mechanical seal 31 is engaged by the lower edge of the wing 19 and is deflected downwards (as shown by a comparison of the positions in which the element 31 is shown in FIGS. 7 and 6) in order to form an auxiliary mechanical seal. The applicator casing is now hermetically sealed from the atmosphere. FIG. 6 better shows the relative positions of the internal members of the housing in this

condition.

  If too high a pressure begins to accumulate inside the casing, the body 3 initiates a rise movement. A small space 41 is provided between the surface 25 of the rib 21 and the surface 39 of the rib 33 to allow the movement of these parts relative to each other. When the pressure rises inside the container, the surface 25 rises on the inclined surface 39, which has the effect of spreading the upper edge of the cover 5 and reducing the compression of the ring 17. seal is then loosened and the vapors can be vented. Figure 7 shows the relative positions of the parts in the

ventilation condition.

  When the pressure prevailing inside the container is released, the body 3 automatically descends by sliding on the surface 39 until the upper edge of the skirt 29 of the cover 5 bears against the ring 17 and

  compress it to close the container tightly.

  In this condition, the container is again in the sealed position shown in Figure 6. The automatic return of the body 3 from the position of Figure 7 to that of Figure 6, after the ventilation of the pressure prevailing inside the container, is insured

  by several features of this embodiment.

  Firstly, the cover 5 is made of a plastic material having elastic characteristics and elastomeric properties. In the position of ventlatiorn shown in Figure 7, the skirt 29 of the hood 5 is fléecnie outwardly Due to its elasticity, when in this position the skirt 29 is subject to

  a certain tension that tends to bring her back inwards.

  When the pressure prevailing inside the container is eliminated, this force tends to lower the body 3 on

  the inclined surface 39 of the rib 33.

  Another feature of this embodiment providing an automatic return of the body 3 from the position of FIG. 7 to that of FIG. 6 during the elimination of the pressure in the container is the difference in inclination between the surface 25 of the rib 21 and the surface 39 of the rib 33. This difference is such that, when the body 3 rises under the effect of the pressure prevailing inside the reciplent, the rib 21 makes a tight fit with the rib 33. The difference in inclination between the surfaces 25 and 39 can vary substantially. A value of about 15 is a very suitable difference. In the embodiment shown, the angle formed by the surface 25 with the horizontal is about 300, while the angle formed by

  the surface 39 with the horizontal is 45 ".

  Figure 8 shows a variant of the invention using a sealing tape 45. This tape is applied so as to cover the seal formed when the body 3 and the cover 5 are assembled. The rubah advantageously comprises a primer 47 which can be grasped to allow the removal of the ribbon 45 when the casing is about to be used. The sealing tape 45 is generally made of a self-adhesive, moisture-proof tape. This tape may be, for example, a polyester strip marketed under the name

of "MYLAR".

  Figure 9 shows another embodiment of the invention in which the vertical skirt 19 'of the body 35 has a circumferential groove 18' in which a compressible ring 17 'is disposed. The outer surface of the ring 17 'protrudes outwardly from the outer surface of the vertical skirt 19' so as to provide a tight circumferential seal with the inner surface of the cap 5 ', close to the upper end thereof. latest. This tight seal is established even before the cover 5 'and the body 3' are locked mechanically and elastically to each other. This has the advantage of forming a seal, even in the case where the consumer does not

  do not put the hood back in the fully locked position.

  This variant of the invention also allows the ventilation of the container when an undesirable pressure of vapor appears in the latter. If a pressure of alcohol moves inside the container, it causes an expansion of the cover 5 'which thus moves away from the ring 17'. This allows the passage of vapors on the compressible ring 17 '. When the pressure inside the container becomes equal to that of the atmosphere, the elastomeric properties of the hood 5 'bring the latter back

in its normal position.

  In this variant, the cover 5 'is made so that the thickness, presented in cross section by its wall to the upper part, is less than that presented by its lower part. In addition, a flexible mechanical seal 31 'is made to tap upwardly and inwardly from its point of origin in the hood 5' to its free edge. The angle made by this joint

  mechanical 31 'with the vertical can vary significantly.

  In an exemplary embodiment, this angle is about 600.

  In another variant of this embodiment, the lower lip of the body 3 'can be made to form an acute angle with the vertical and to loqeer thus in the angle formed by the seal 31' and the vertical. The angular dimension of these elements can also vary substantially. However, in a case also typical, the inclined edge of the lower lip of the body 3 'makes an angle of about 450 with the vertical, while the angle formed between the seal 31' and the vertical is

about 30.

  The variant of the invention shown in FIG. 9 is also made in such a way that the upper lip of the cover 5 'has a chamfer 15'. This brings several advantages. Thus, the gap appearing between the hood and the body when the parts are assembled is reduced. In addition, this facilitates the assembly by the consumer of the hood and the body and reduces the dangers presented by the presence of sharp edges formed in the plastic material. In addition, this also promotes better nesting

waterproof.

  The resilient locking device of the embodiment shown in Fig. 9 is slightly different from that of the other embodiments shown. In this case, an outwardly protruding rounded rib 27 'is formed on the outer wall of the flange 19' so as to engage with a similar rounded rib 28 'projecting inwards from the

  inner surface of the hood wall 5 '.

  FIG. 10 represents another embodiment of the invention which avoids having to use a ring similar to the ring 17 shown in FIG. 6. As in the other embodiments shown, this variant comprises a cover 5 "and a body 3". A flexible mechanical seal 31 "is also used, this seal having a structure and a function similar to those of the joint

mechanical and flexible 31 or 31 '.

  To seal this embodiment of the invention, the wall 51 of the hood 5 "tapers upwardly and outwardly to its free edge 53 so as to have an inclined portion 55. A shoulder is cut in the lower region of the inclined portion 55 to form a flange 57 which contacts a corresponding flange 59 of the body 3 ", described in more detail below, to form a latch which maintains the hood 5 "and the body 3" engaged one with

the other when they are assembled.

  The wall 61 of the body 3 "is tapered downwardly and inwardly to its free edge 63. The latter is in the form of an unfreak which allows it to be slid downwards in a space 65 located on one side of the flexible joint 31 ". A shoulder is cut in the upper part of the inclined wall 61 so as to form a flange 59 which, as indicated above, performs a locking

with the rim 57.

  To achieve the gasket sealing with the atmosphere, the body 3 "and the cover 5" are made of different materials, generally plastics having different degrees of flexibility. In a preferred embodiment of the invention, the body 3 "is made of rigid polypropylene while the cap 5" is

  made of flexible polyethylene (high density).

  The body 3 "and the hood 5" are dimensioned so that, when assembled and pushed into the interlocking position as shown in FIG. 10, the tapered wall bends outwards. Since the material of this wall is flexible, it is subjected to a certain tension which recalls it inwards. This achieves a

  joint between the inclined surfaces of the walls 55 and 61.

  This variant of the invention also allows the ventilation of the container with the atmosphere when the vapor pressure prevailing inside this container becomes too high. In this case, a slight upward movement of the body 3 "under the effect of an increase in the internal pressure breaks the seal formed between the inclined surfaces of the walls 55 and 61, which causes a

  ventilation of the container with the atmosphere.

  In some cases, the apparent surface of the applicator 9 as shown, for example, in Figure 2, may be too rough to be applied against underarm skin of the subjects. If this is the case, it is possible to remedy this defect by heating the surface of the applicator, for example by means of a hot plate. This results in the formation of a smooth skin on the surface of the applicator, which can alleviate any inconvenience

  resulting from the surface of the applicator.

  Another feature of the invention lies in the fact that, during the stays in the standing position to which the housings are subjected worms are not used, the body 3 containing the capillary applicator 9 loaded with liquid antiperspirant composition is in the inverted position, c that is, the capillary applicator 9 is turned downward. In this way, the liquid contained in the applicator flows by gravity towards the end of use of the applicator. Thus, the applicator is ready to be used immediately to dispense the effective dose of antiperspirant. However, the antiperspirant fluid can not leak from the applicator because of

  capillary forces exerted by the applicator on the liquid.

  Thus, gravity forces are balanced by capillary forces. When the loaded applicator is applied under the arm with a certain pressure, the liquid deposited on the skin comes from relatively superficial areas of the applicator. The liquid thus removed from the applicator is replaced by liquid contained in more interior parts of this applicator. The filamentary material used in the manufacture of the applicator elements according to the invention may vary substantially. For example, nylon monofilaments, cellulose acetate, polypropylene, etc., can

  to be used. However, the preferred material is poly-

  propylene, because it has several advantages. This material is inert to virtually all active antiperspirants. In addition, the delivery rate - appears to be more uniform with a polypropylene applicator and the dispensing of the required dose of active antiperspirant, in a reasonable number of movements, seems easier to achieve when the applicator is made of polypropylene filaments. and is produced by carrying out the process described in the US patent

No. 3,111,702, cited above.

  Various antiperspirant active materials may be included in the formulation of the antiperspirant composition of the invention. Examples include aluminum chlorohydroxide and aluminum hydroxybromide, aluminum chloride, and antiperspirant complexes. aluminum / zirconium / glycine, described in the US Pat.

  United States of America N 3 792 068.

  The preferred aluminum compound for the preparation of the complex described in the aforementioned U.S. Patent No. 3,792,068 is aluminum chlorohydroxide of formula A12 (OH) 5Cl2H2O. The preferred zirconium compound for the preparation of the complex described in US Pat. No. 3,792,068 is

  zirconyl hydroxychloride of formula ZrO (OH) C13H20.

  The preferred amino acid for the preparation of the complex described in the aforementioned Patent No. 3,792,068 is glycine of formula CH 2 (NH 2) COOH. Salts of these amino acids can also

  be used in such antiperspirant complexes.

  Other active substances suitable for use in the present invention include mixtures of aluminum chloride with other less acidic aluminum salts than aluminum chloride, for example aluminum hydroxychloride (or chlorhydroxide). 'aluminum). Canadian patent N 958 338 describes such salts. However, the preferred antiperspirant is

aluminum sesquichlorohydrate.

  The amount of active antiperspirant that can be used can vary substantially. In general, it constitutes from about 10 to 40%, by weight, of the total weight of the fluid composition used in the preparation of the

applicator housing.

  A large part of the fluid carrier used in the preferred antiperspirant compositions for the invention is ethyl alcohol. However, the amount used depends on other elements of the composition, and in particular the amount of water that it can contain. In general, this material comprises from about 40 to 90% by weight of the total weight of the antiperspirant composition, the preferred range being from about 50 to 65% by weight. 1 6 It is also possible to use water in large quantities in the fluid vehicle. In this case, the water constitutes about 5 to 80% by weight of the total antiperspirant composition. In a preferred embodiment of the invention, the water is present at a rate of about 40 to

% in weight.

  In addition to the above mentioned substances, the antiperspirant composition used may also contain ingredients that are commonly used in aqueous or alcoholic antiperspirant compositions. These ingredients include neutralizing agents (eg glycine), volatile or non-volatile emollients (such as cyclomethicone, isopropyl myristate),

  surfactants (such as poly-2-isostearate);

  oxyethylene 1 "Aerosurf 66-E-2" J), perfumes, dyes, preservatives, etc. The following examples further illustrate the present invention. It is clear, however, that this

  last is not limited to these examples.
