Definitions

  • the present invention relates to an improved dispenser for applying solid products to surfaces and, more particularly, to a cylindrical dispenser for applying topical, solid, personal care products, such as deodorants and/or antiperspirants to the axillae of users.
  • Dispensers for applying solid, topical products are provided in several different forms and configurations, such as narrow tubes for dispensing lip care products or larger cylinders for dispensing underarm products, such as deodorants or antiperspirants.
  • dispensers require a friction or screw feed to advance and retract the product. If the product is not retracted sufficiently, the exposed surface will be deformed when the cap is replaced on the dispenser.
  • the application surface is normally flat which does not conform to the shape of an armpit and makes application relatively difficult.
  • Screw feed is expensive to fabricate and does not function smoothly.
  • the available solid applicators require manufacture of a relatively large number of parts which further adds to the cost of the product.
  • dispensers and applicators which comprise a hollow first cylindrical member and a second slightly smaller cylindrical member disposed therein.
  • Representative examples of such prior art are FR-A-2259560, AT-A-97798, US-A-2276047 and US ⁇ A ⁇ 2814153.
  • the element In order to form the element by pouring molten precursor into the cavity, same must be fluid-tight and the inner surface thereof must be smooth and continuous. Furthermore, the cavity must be symmetrical or the element that is formed will not rotate.
  • an applicator comprising: a hollow, shallow, circular first cylinder having first and second flat parallel end surfaces interconnected by a peripheral outer wall, said first cylinder being constituted by a relatively large main body section incorporating major portions of said end surfaces and said wall and a relatively small minor section which incorporates minor portipns of said end surfaces and said wall, said minor section being detachably engagable with said main body section, and defining a removable cap for said main body section, said first surface having a centrally disposed circular opening located in the main body section and communicating with the interior of the main body section; and a circular member accessible from the exterior of said first surface and disposed in a manually rotatable manner within said opening, said member having an axis of rotation extending through the center of said opening at right angles to said surfaces, said member having an integral extension which extends from said member and towards said second surface and which has an axis of symmetry coincident with said axis of rotation, contours of the engaging edges of the two sections conform
  • a method of filling a dispenser characterised in that said method comprises the steps of filling the symmetrical cavity of a hollow, shallow, circular cylinder having opposed parallel side walls joined to a peripheral outer wall having a central, circular opening in one of the side walls through the opening with a congealable liquid; placing the hub portion of a circular handle member into the liquid and rotatably and sealingly inserting the circular member into said opening, congealing said liquid to form an element firmly engaging said hub portion.
  • the dispenser of the invention includes a contoured, solid element that is more compatible in shape with the human axilla.
  • the arcuate convex waxy surface readily fits the axilla and application of the solid product by stroking is both easy and comfortable, and more complete and effective coverage is accomplished in fewer strokes:
  • the novel dispenser of the invention is formed of few and easily moldable parts.
  • the solid element can be formed by casting inside the dispenser. Both of these factors are responsible for lower manufacturing cost.
  • the element is readily covered without contact with the exposed surface and fresh element is moved into place by rotation rather than by linear movement of the element.
  • the dispenser is of a disc-shape which is easy and comfortable to hold and manipulate and is more compact for storage in drawers or in travel containers.
  • the dispenser of the invention can be utilized to apply any solid to a surface by rubbing the contoured element on the surface.
  • the element comprises mainly inert carrier, such as a waxy solid containing a minor amount of active ingredient.
  • the inert carrier can be a wax or a gel.
  • the element is preferably formed of a material that can be set from a liquid to a more rigid state.
  • the inert carrier can be a thermoplastic material, such as a meltable wax or a thermosetting material that gels or sets by chemical curing agent, and/or heat or radiation.
  • the element can be a household care product, such as an insecticide or furniture wax, etc., or a personal care product containing a dispersion or solution in the solid carrier of an active ingredient, such as an insect repellent, fungicide, sunscreen agent, analgesic or various dyes, emollients, and the like, for a lip blush, facial blush, or eye shadow.
  • an active ingredient such as an insect repellent, fungicide, sunscreen agent, analgesic or various dyes, emollients, and the like, for a lip blush, facial blush, or eye shadow.
  • the active ingredient can be absorbable into the endodermis, such as Vitamin K or heparin.
  • the element can be small in diameter, and or thin, such as for lip or eye product application, or wide and/or large in diameter, such as for applying a body liniment.
  • a hollow shallow circular first cylinder is employed.
  • the first cylinder has first and second parallel flat end surfaces which are interconnected by a peripheral outer wall.
  • the first cylinder consists of a relatively large main body section incorporating major portions of said surfaces and said wall and a relatively small minor section which incorporates minor portions of the surfaces and wall.
  • the minor section is detachably engageable with the main section and constitutes a removable cap.
  • the contours of the engaging edges of the major and minor sections are irregular in shape but conform to each other.
  • the first surface has a circular opening centrally disposed therein which is located in the main section and which communicates with the interior thereof.
  • a circular member accessible from the exterior of said first surface is disposed in and manually rotatable in the opening.
  • the member has an axis of rotation which extends through the center of the opening at right angles to the end surfaces.
  • the member has an integral, rigid extension extending from the member toward the second surface.
  • the extension has an axis of symmetry coincident with the axis of rotation.
  • second slightly smaller solid cylinder element which contains an active ingredient, such as a deodorant, has the same shape as the first cylinder and is disposed rotatably therein.
  • the second cylinder is rotatable about the axis of rotation.
  • the extension penetrates the second cylinder and is non-rotatably secured thereto.
  • the cap In use, the cap is removed, exposing a portion of the second cylinder.
  • the element can then be applied by rubbing to a surface in a conventional manner being particularly easy to apply to armpits because of the conforming shapes of the element and armpits.
  • the member can be rotated to expose an adjacent unused portion thereof.
  • the relative sizes of the second cylinder and the main section are so chosen that essentially the entire second cylinder can be used up before the dispenser is unusable.
  • a hollow shallow circular plastic first cylinder has first and second parallel flat end surfaces 10 and 12 interconnected by a peripheral outer wall 14.
  • the first cylinder consists of a relatively large main body section which incorporates major portions of the end surfaces and outer wall and which is identified by the underlined number 16, and a relatively small minor section which incorporates minor portions of the end surfaces and outer wall and which is identified by the underlined number 18.
  • Section 18 detachably engages section 16 and constitutes a removable cap.
  • Section 16 has a top opening with a peripheral lip 100 having a groove 102 which is engaged removably by a mating groove in the bottom opening of section 18 which mates therewith.
  • These top and bottom mating openings have mating edges of irregular shape but conform to each other. These mating edges are chosen in such manner as to enable each section to be molded in a single plastic piece which can be easily removed from the mold.
  • All parts of the invention disclosed other than the dispensable element itself can be formed out of any tough solid, such as metal or resin, but are preferably formed from a suitable casting or molding grade synthetic, organic resin.
  • End surface 10 has a circular opening 20 centrally disposed therein located in section 16 and communicating with the interior thereof.
  • a circular member 22 with an integral extension is disposed manually rotatably in the opening.
  • Member 22 has a peripheral lip 24 which enables it to be snap fitted into the opening with the extension extending in the interior of the main section between the member and end surface 12.
  • the member and extension have an axis of rotation 26 which extends through the center of opening 20 at right angles to the end surfaces. This axis constitutes an axis of symmetry for the extension.
  • the extension can be provided in various shapes, such as a single flat vane or an open or closed triangle, or other polygonal shape.
  • the extension can be of low profile in certain uses, as long as it locks the solid element to the circular member 22.
  • the extension shown consists of three like flat plates 28 which extend at right angles to the end surfaces, are confluent at the axis of symmetry, and extend radially outward at 0 degrees, 120 degrees and 240 degrees therefrom.
  • the edge of each plate adjacent end surface 12 has a small prong 30.
  • End surface 12 has six small holes 32 disposed equidistantly along a circular path.
  • the member and extension are slightly movable back and forth along the axis of rotation to enable the prongs to detachably engage selected holes 32.
  • a second slightly smaller solid cylinder 34 of the same shape as the first cylinder is a solid element and is disposed rotatably about the axis of rotation within the first cylinder.
  • the blades of the extension penetrate the second cylinder to key the extension and the member to the second cylinder whereby the cylinder 34 can be rotated by rotating the member.
  • the prongs and holes enable the cylinder to be selectively locked in any desired position or rotation.
  • the cylinder 34 can be a waxy solid which can be poured as a liquid into the first cylinder before the member with extension is inserted into position. The liquid and cylinder are then at a temperature some tens of degrees or higher above normal ambient temperatures. As the liquid cools to room temperature it solidifies, shrinks and hardens whereby the resultant solid second cylinder is keyed permanently to the extension and is rotatable as previously described.
  • the minor body section can have an integral small extension 36 which functions as a stand when the structure shown in Fig. 1 is inverted as shown in Fig. 9.
  • the circular member 22 can have two holes joined by a bridge for receiving fingers of the riser.
