Definitions

  • the invention relates to personal care. More particularly, the invention relates to applicators for underarm antiperspirant and/or deodorant.
  • dispenser/applicators for personal care products One particular area involves applicators for solid or gel antiperspirant and/or deodorant compositions.
  • Applicators for solid and gel compositions are typically thoroughly similar to each other, with a piston (platform) upwardly movable within a cylinder (barrel) to progressively drive the composition out the barrel upper end. Due to the relative lack of stiffness of many gels and soft solids, dispensers for such compositions commonly include apertured applicator elements across the upper end of the barrel.
  • compositions are particularly sensitive to pressure. Accordingly, the imposition of residual pressure after the initial discharge of composition may be problematic.
  • Soft solid compositions (especially those containing silicone oils) are particularly sensitive to pressure-induced microstructural changes.
  • pressure relief mechanisms have been provided. Exemplary pressure relief mechanisms are shown in US Patents 5,000,356, 5,547,302, 5,697,531, 5,961,007, 7,329,403, and 7,374,360.

  • That dispenser includes a one-piece molded combination elevator screw and handwheel.
  • Superimposed reciprocal movement of the screw is caused by camming interaction of respective groups of ratchet teeth on the molded element and barrel.

  • the threaded shaft is in engagement with a complementary feature (e.g., an internal thread) 48 of the platform.
  • the illustrated elevator screw combination 42 (FIG. 6) is a two-piece assembly.

  • the exemplary two pieces include a first piece 50 (FIGS. 7&8) having a shaft whose distal portion forms the threaded shaft 44 the second piece forms the knob 46. At a proximal end of the piece 50, it bears a feature 52 for engaging the adjuster knob.
  • the exemplary feature 52 is formed as an endplate. Spaced distally of the endplate, the piece 50 comprises a generally circular boss 60 having an underside 62 generally toward the plate 52.

  • the barrel retains the elevator screw for rotation about the axis 500 and positions it axially.
  • the axial position varies with rotational orientation (about the axis 500) to provide a pressure relief action.

  • the exemplary footprint of the applicator 20 is transversely elongate (e.g., elliptical) with the compartment 90 opening to the front 92 and rear 94 of the barrel to allow user finger access to the lateral surface 110 (FIG. 1) of the knob sidewall for rotating the knob.
  • the exemplary applicator and barrel share a longitudinal vertical centerplane 510 and a transverse vertical centerplane 512.
  • the base has a transverse web 120 extending inward to a collar 122 that extends upward to an upper rim 124 and downward to a lower rim 126.
  • the rims 124 and 126 define a circumferential waveform having one or more respective lower extremes 130 and 134 and one or more respective upper extremes 132 and 136.

  • a barb 138 (FIG. 5A) of the barrel captures an underside of the knob 46 web 66 to restrict downward motion of the knob.
  • the web 66 upper surface abuts the underside of the web 120 to restrict upward movement of the knob and thus hold the knob in essentially a single axial position.
  • the exemplary screw comprises two sets of structural buttresses 140, 142 linking the shaft portion to the endplate 52 and the boss 60.
  • the buttresses are formed as
  • the buttresses 140 serve a dual function in also cooperating (via a step 144 serving as a lower follower (FIG. 4 A)) with the lower rim 126 to axially position the screw piece 50.

  • the lower extremes 70 register with the lower extremes 130 and the upper extremes 72 and 132 register.
  • this involves essentially continuous circumferential contact between the rim 124 and the boss underside 62.
  • the boss 60 underside 62 will ride up the rim 124 at a pair of diametrically opposite contact locations (for the two-cycle waveform).
  • a fully raised or topped orientation will be reached where the lower extremes 70 contact and register with the upper extremes 132. This is a maximally raised orientation. In the exemplary two-cycle waveform, this involves a 90° rotation.
  • the first 90° (quarter turn) of rotation raises the platform by A+B (Plot III of FIG. 20).
  • the second raises it by A-B or lowers it by B-A. If B>A, then the second 90° 90° actually lowers the platform. This lowering performs the pressure relief or suckback function.
  • Exemplary B is thus greater than A, more particularly, at least 102% of A or at least 110% of A or an exemplary 102% to 150% or 110% to 120%.
  • Exemplary B is 0.20 millimeters to 4.0 millimeters, more particularly 0.50 millimeters to 1.50 millimeters.
  • Plot III could also depart from the illustrated two linear stages.
  • the Plot III transition between the upstroke and the suckback interval could be shifted.
  • the beginning of the interval could be shifted away from the quarter turn condition (e.g., delayed).
  • a net upstroke could begin in advance of the zero/half turn condition.
  • the continuous wave forms of both the upper rim 124 and the boss underside 60 allow either to be treated as a waveform track and the extremes of the other to be treated as a follower.
  • Alternative implementations may clearly show one to be the track and the other the follower (as in the case of the lower rim 126 and steps 144).
  • the significance of the two-cycle waveform relates to user-perception.
  • the elongate knob footprint creates a user-perceptible difference between the bottomed conditions (FIG. 1 and 2) and the topped conditions (FIG. 11).
  • the long dimension of knob footprint aligns with the shorter dimension of barrel footprint so that the knob protrudes conspicuously from the front and rear of the barrel.
  • the user will continue the rotation through the topped condition rather than stopping there.
  • Exemplary materials for the various pieces are injection molded plastics as are conventional in the art. Similarly, conventional assembly techniques are appropriate.
  • FIGS. 21-31 show a second embodiment 200 and FIGS. 32-37 a third embodiment 400 each having a single piece forming the screw shaft and knob.
  • the third embodiment knob forms the base of the applicator.
  • FIGS 21 and 22 show the second applicator 200 having a body having a barrel 202.
  • the screw 204 knob 206 has a slightly different footprint formed by four intersecting arcs.
  • the longer of two dimensions of the footprint aligns with the longer direction of the applicator footprint (along the transverse centerplane). Accordingly, when rotated 90° to the second condition of FIG. 25, this allows end portions of the knob footprint to protrude front and back from the barrel.
  • the screw has a pair of radially protruding arms 220 diametrically opposite each other and aligned with the lower extremes 70.
  • the screw 204 includes a vertically protruding boss 230 having a lateral perimeter 232.
  • Petals 234 separated by gaps 236 extend radially inward and upward from the boss to the root of the screw shaft.
  • the petals provide compliance to flex to allow the threaded shaft to reciprocate while the knob remains axially fixed.
  • FIG. 27 shows interference whereas the physical threaded portion of the screw would be shifted upward with the petals flexing upward.
  • the applicator 400 has a barrel 402 otherwise similar to the barrel 202 and a screw 404 otherwise similar to the screw 204.
  • the knob 406 forms the entirety of a base of the applicator (e.g., so there are not portions of the barrel protruding down alongside the knob to partially laterally block/cover the knob) and is thus fully laterally exposed.

Abstract

L'invention concerne un applicateur de soins personnels (20 ; 200 ; 400), lequel applicateur a une plateforme (40) montée pour un mouvement à l'intérieur d'un fût. Un élément de vis (42 ; 204 ; 404) a : une vis (44) s'étendant dans une ouverture de la plateforme, de telle sorte que la rotation de la vis autour d'un axe (500) provoque un déplacement de la plateforme et de la vis par rapport au fût parallèlement à l'axe. Un fût et élément de vis a une piste (62 ; 124 ; 126 ; 126) circonscrivant l'axe et ayant une surface avec une position axiale variant avec la position périphérique autour de l'axe. L'autre fût et élément de vis comprend un contre-élément (124 ; 62 ; 144 ; 220) venant en prise avec la piste de telle sorte qu'une rotation continue de l'élément de vis autour de l'axe provoque un mouvement réciproque de la vis par rapport au fût. La piste est formée de façon à produire deux cycles de mouvement relatif pour chaque rotation de l'élément de vis.
