Definitions

  • the present invention relates to a package for a fluid cosmetic composition and more particularly to a package suitable for dispensing a flowable antiperspirant or deodorant composition.
  • Flowable antiperspirant or deodorant compositions can comprise a number of forms, such as a liquid or a cream, or possibly a gel or micronized powder. Such flowable compositions have been dispensed in a variety of packages.
  • a conventional package comprises a rigid tubular container (a barrel) provided at one end with a convex distributing surface having an aperture connecting to the interior of the barrel and at the other end a piston located within the barrel and a mechanism for moving the piston axially toward the convex surface, and thereby exuding formulation through the aperture.
  • a rigid tubular container a barrel
  • a piston located within the barrel and a mechanism for moving the piston axially toward the convex surface, and thereby exuding formulation through the aperture.
  • This is commonly called a mushroom package on account of its physical resemblance to a mushroom. It is a very effective package for dispensing and distributing creams or gels topically, but the package itself can represent a significant fraction of the overall cost of the package plus contents .
  • a flowable cosmetic composition such as an antiperspirant or deodorant composition
  • a package for topically applying a fluid cosmetic composition to human skin which comprises (i) a container having
  • a sidewall made from one or more impervious sheets having opposite longitudinally extending first and second edges, a first strip adjacent the first edge and a second strip adjacent to the second edge, which sheets are flexible in a transverse direction, the first strip of one sheet being sealed to the second strip of the same sheet or to the second strip of a contiguous sheet when there are two or more sheets forming a closed chain, thereby enclosing a longitudinally extending volume
  • a closure positioned across the second end, the closure including an oval top wall with opposite exterior and interior surfaces, a skirt surrounding the top wall and at least one aperture formed in the topwall and communicating with the second non-linear aperture and (iii) a cap seatable over at least the aperture formed in the topwall of the closure, the cap including a roof with an inner surface and a flat outer surface, and a set of plugs projecting downwardly from the inner surface of the roof, the plugs being equivalent in number to the apertures and seatable therewithin to prevent egress of flowable substance from the container.
  • the package of the present invention provides an elegant means of forming a container for a fluid cosmetic composition, and particularly one which can be employed in conjunction with compositions in cream or gel form.
  • the choice of a transversely flexible material to make the sidewall enables it to conform easily to the applicator for the composition.
  • the sidewall deforms, until eventually the container is empty and the sidewall is flat. This deformation has two advantages. First, it becomes readily apparent when the container is almost empty, providing a timely warning to the user that further composition needs to be purchased. Secondly, the container empties without a corresponding ingress of air. This avoids or at least minimises any oxidation of the composition which air might cause.
  • the container is formed from either one flexible sheet which is bent around and sealed longitudinally or preferably a plurality of sheets which are joined longitudinally to form a chain which is bent round and sealed to enclose a volume.
  • two sheets are employed.
  • the sheet or chain of sheets forming the sidewall is sufficiently flexible in the transverse direction to be bent around without cracking.
  • the sidewall exhibits sufficient rigidity longitudinally such that the container can stand upright, resting on the bottom edge of the sheet or sheets .
  • the thickness of the sheet is desirably selected in order to combine appropriate longitudinal rigidity with sufficient transverse flexibility.
  • the sheet thickness is often selected within the range of from 0.02 to 1 mm, the thickness selected often taking into on the sheet material employed to the sidewall .
  • the contents of the container may assist in providing longitudinal rigidity to the container.
  • the sidewall sheets are preferably formed from a thermoplastic material, such as polyethylene or polypropylene and extruded sheets are especially suitable.
  • a thermoplastic material such as polyethylene or polypropylene
  • extruded sheets are especially suitable.
  • Low density (LDPE) and ultra- low density (LLDPE) polyethylene sheets are particularly suitable, and most preferably co-extruded LDPE and LLDPE sheets are employed.
  • the sheets can further comprise reverse printed polyester.
  • the longitudinal join between either the first and second strips or between the respective strips on contiguous sheets forms an external tab, that is to say that the inner face of one sheet is joined to itself or to the inner face of a contiguous sheet.
  • the seal can be effected by adhesive for the sheet material disposed continuously along the strips adjacent to the sheet edge.
  • the sheets are made from a thermoplastic or have a thermoplastic face that is to be joined, the sheets can be joined by heat welding.
  • the sidewall is preferably made from two side sheets.
  • the two side sheets can be placed the one upon the other and aligned, and joined whilst the sheets are flat, if desired. Thereafter, the side wall can be bent to enclose a suitable volume, for example by pushing the tabs towards each other.
  • the two sheets are each rectangular and sealed together along the longer edges, most preferably to the bottom edge.
  • the ratio of the length to breadth of the sheet is preferably from 2:1 to 5:1 and especially from 3:1 to 4:1.
  • the bottom edges of the sheets are not sealed together, but by virtue of being straight, enable the container to stand upright reasonably stably on its base after it has been filled.
  • the container preferably is dimensioned to contain from 20 to 100 mis cosmetic composition, such as antiperspirant or deodorant composition, and especially from 40 to 70 mis.
  • the first end of the container is closed by an end sheet, which is impervious to the fluid cosmetic composition.
  • the sheet is preferably flexible, and highly desirably is formed from a thermoplastic material such as those contemplated for the sidewall.
  • the end sheet is disposed within the first end such that a strip on the end sheet adjacent to its circumferential edge and on its inner face is in contact with the inner face of the sidewall, adjacent to the bottom edge of the sidewall.
  • the end sheet advantageously is a planar sheet which is bent and positioned such that in the container it is non-planar, and particularly is convex in profile, normally extending downwardly in longitudinal cross section from edge to middle of the side shhets. This can be achieved by the end sheet advantageously being sealed to the side sheets closer to the second end at the side-edge of the side sheets and progressively further from the second end approaching the middle of the side sheets, normally symmetrically.
  • the sidewall preferably formed from two side sheets
  • first end of the container desirably form a pouch made from two sheets forming the sidewall and an end sheet, each made of a thermoplastics material, sealed together by hot welding contiguous faces adjacent to their edges.
  • the pouch at or adjacent to its base (first end) in transverse cross section usually has a maximum front to back spacing between the side sheets relative to the width of the pouch, of from 4:3 to 3:1 and particularly about 2:1, normally tapering to an acute nterfacial angle at the longitudinal seal of the side sheets.
  • the second end of the container is closed by a closure which comprises a topwall from which a skirt depends.
  • the skirt fits outside or preferably within the sidewall and is advantageously sealed to the sidewall along a strip adjacent to the top edge of the sidewall and the bottom edge of the skirt.
  • the closure is desirably rigid and imparts to some extent rigidity to the container.
  • the skirt may be extended downwardly to form lugs in the vicinity of the aperture or apertures in the topwall, thereby further strengthening the container.
  • the topwall preferably presents a smooth arcuate surface externally, especially when viewed in side cross section, often having a wide angle of curvature. Its profile most desirably resembles the profile of a used solid antiperspirant stick.
  • the topwall defines at least one and preferably a plurality of apertures, such as three, through which the composition can flow.
  • the apertures are preferably positioned within a central area of the topwall .
  • the shape of the apertures is at the discretion of the package manufacturer. Suitable shapes include round, square, rectangular or serpentine apertures, the rectangular or serpentine apertures preferably extending at least predominantly transverse to the major axis of the topwall.
  • the cap if desired, can be separate from the closure, for example comprising a roof from which downwardly project plugs that are congruent with the apertures in the topwall of the closure, and which roof is surrounded by an apron which push fits onto the skirt of the closure the roof.
  • the cap comprises a flap which conforms to the shape of the apron and topwall of the closure, is hinged to the closure along a line just above and parallel to the sidewall of the container at or close to the minor axis of the topwall (a living hinge) .
  • the flap desirably covers the central area of the topwall and has plugs which downwardly project from its inner face that are congruent with the apertures in the topwall of the closure.
  • the flap preferably has a flat outer surface, permitting the package, if desired, to adopt an inverted stance.
  • the closure and the cap are each desirably moulded thermoplastic, for example polyethylene or polypropylene and especially a high density polyethylene.
  • the cap and the closure are preferably moulded in one piece.
