Definitions

  • the present invention relates to packaging for high viscosity fabric treatment fluids which are dispensed by pouring.
  • the present invention provides a consumer package comprising a reservoir for containing a high viscosity fabric treatment fluid, the reservoir comprising an internal surface, the internal surface comprising at least one recess, wherein the or each recess is elongated, curved and follows continuous path spiraling relative to the longitudinal axis of the package and in that the path extends greater than 90 degrees measured as a rotation about the longitudinal axis of the package.
  • the present invention provides a consumer package comprising
  • the invention comprises the combination of the package of the first aspect or the second aspect, together with high viscosity fabric treatment fluid.
  • the invention provides a method of rinsing a package containing a high viscosity fabric treatment fluid according to any of the above aspects, wherein the method includes the step of adding water and agitating the bottle to create a fluid swirl directed by said recess/es.
  • the invention affords the advantage that, in use with pack in motion, the recesses direct the fabric treatment fluid to swirl in vortex-like motion around the longitudinal axis of the package.
  • the arrangement of recesses facilitate fluid swirl when the pack is agitated. This is helpful in improving the rinsing action to ensure the entire product is removed and used.
  • the invention facilitates consumer enjoyment of the full benefit of all the contents and also ensures the bottle is clean prior to recycling.
  • the arrangement of recesses direct fluid more quickly to the base when there is very little fluid left remaining the pack. With more of the liquid drained down to the base - the consumer can gauge if they have sufficient liquid remaining for their needs. This is especially advantage if the pack has been previously tipped upside down to empty. Whilst liquid collects at the base under gravity, if the pack has been tipped up (as happens in use when the consumer tries to empty) more of the liquid may gather on the upper walls. So once the bottle is returned to its upright position, the recesses help guide the liquid back down to the base. Even if consumers cannot see the inside clearly, as is the case with an opaque, spouted bottle, the collection of liquid at the base is helpful for gauging by weight as the pack is rocked to the side or via a transparent/translucent viewing window.
  • the package may be partially or wholly opaque and comprise one or more fluid-level viewing windows, said window/s being translucent or transparent.
  • At least a portion of the bottle is transparent.
  • the recesses may be visible to the consumer, and also the interaction of the recesses and the fabric treatment fluid as described above.
  • the or each wall may be defined by an edge region, which may be a corner edge of the package interior such that the walls lie in different, inclined planes, thereby presenting as discrete regions.
  • the or each recess has smoothly shaped sides when viewed in transverse cross section.
  • the or each recess is V-shaped at its base and then curves smoothly, with decreasing gradient as a function of the recess height, such that the recess curves smoothly into surrounding surface/wall.
  • the or each recess is formed by the intersection of two convexly curved interior surfaces or walls.
  • the curvature may be sub parabolic/a parabolic spandrel.
  • the or each recess comprises an S-shaped curve when the reservoir wall/surface is viewed as side elevation (from the side).
  • the package comprises an upper neck region, and the or each recess begins at the neck region.
  • the package comprises at least two recesses, which both begin at the neck region.
  • the or each recess begin at the neck region and follow a spiral path downward around the bottle.
  • the neck region may be taped so as to narrow toward a dispensing aperture.
  • the dispensing aperture may comprise a spout member preferably, the or each recess begins at the base of the spout member.
  • the or each recess path begins at opposite positions on the bottle neck region, whereby the start position is spaced apart by greater than 90 - 180 degrees, preferably 170-180 degrees, most preferably 180 degrees. This creates a pair of staggered spiral recesses.
  • the package comprises four walls and the at least one recess comprising a continuous S-curve (in side elevation) which spans three of said walls.
  • the pack comprises a handle recess or aperture.
  • the elongate curved recesses are directed toward the handle and directed away from the direction of pouring as defined by the spout orientation. This allows the flow of liquid to swirl with less interruption by handle features.
  • the pack comprises a base portion at an opposite end to the dispensing portion, and the pack is stored to rest on the base portion.
  • one or more recesses follow a path from the neck region to the base.
  • the package may be a bottle.
  • the package comprises a plastic.
  • suitable plastic materials include high density polyethylene (“HDPE”), low density polyethylene (“LDPE”), polyethylene terephthalate (“PET”), polypropylene (“PP”), polyvinyl chloride, polycarbonate, nylon, and fluorinated ethylene propylene.

  • the preferred volatile benefit agent is a perfume.
  • the combination of the package and a fluid comprising a volatile benefit agent afford the advantage that whilst the consumer agitates the fluid in the bottle, and consequential swirling motion increases, the consumer experience is greatly enhanced by a greater perfume sensation.
  • the swirling motion increases perfume perception for enhanced enjoyment of recycling-related activities.
  • the volatile benefit agent or at least a portion of said agent evaporates at room temperature.
  • the perfumes of the of the invention preferably comprise an unconfined (also called non-encapsulated) volatile benefit agent.

  • a consumer package a bottle 1 is shown dissembled (cut open) to reveal the interior.
  • the spout has been removed.
  • the package is for uses with a high viscosity fluid, with components as in the above example.
  • the consumer package has a reservoir 3 for containing a high viscosity fabric treatment fluid.
  • the reservoir has an overall continuous internal surface with four contiguous walls 5,7,9,11 .
  • Each wall comprises respective contiguous internal surfaces 15, 17, 19, 21 containing multiple elongate curved recesses 29, 31, 33, 35.
  • the recesses 29, 31, 33, 35 are provided.
  • Certain recesses are formed as a continuous S-curve which spans multiple walls.
  • the package comprises an upper neck region 50 with spout member 55 shown in figure 2 and two corresponding recesses begin at the neck region 50, and more specifically at the base of the spout member 55. These two recesses have start positions at opposition positions of the bottle about 180 degrees apart. This creates a pair of staggered helical recesses. As shown in Figure 3 shows a view of the helical path tracked by the recesses, downward from the neck, around the longitudinal axis of bottle.
  • the package is formed from PET, with a handle 60 and a viewing window (not shown) to show the fill-level of the fluid.
  • the recesses In use with the package in motion eg. By agitation, the recesses direct the fabric treatment fluid to swirl in vortex-like motion around the longitudinal axis of the package.
  • the arrangement of recesses facilitate fluid swirl when the pack is agitated. This is helpful in improving the rinsing action to ensure the entire product is removed and used.
  • the invention facilitates consumer enjoyment of the full benefit of all the contents and also ensures the bottle is clean prior to recycling.
  • the arrangement of recesses direct fluid more quickly to the base when there is very little fluid left remaining the pack. With more of the liquid drained down to the base - the consumer can gauge if they have sufficient liquid remaining for their needs. This is especially advantage if the pack has been previously tipped upside down to empty. Whilst liquid collects at the base under gravity, if the pack has been tipped up (as happens in use when the consumer tries to empty) more of the liquid may gather on the upper walls. So once the bottle is returned to its upright position, the recesses help guide the liquid back down to the base. Even if consumers cannot see the inside clearly, as is the case with an opaque, spouted bottle, the collection of liquid at the base is helpful for gauging by weight as the pack is rocked to the side or via a transparent/translucent viewing window.
  • the package comprises a closure device (not shown) such as an over cap
