Definitions

  • This invention is directed to a disposable, soft walled, handheld dispensing container " suitable for use with foodstuff, condiments, creams and other materials.
  • one very successful container has comprised a plastic container of a size and form suitable for being held in the hand of a user, the container having a removable screw top for inserting product therein, the screw top having an upwardly projecting small dispensing lipped aperture with a pivoted closure cap, for use by a user in dispensing a desired quantity of the contents.
  • the cap In use, the cap is generally pivoted to an open position, clear of the dispensing aperture.
  • the container is then inverted, to assist the viscid contents to flow under the influence of gravity in covering relation downwardly over the inlet to the dispensing aperture.
  • Manual compression of the container walls then expresses a desired quantity of the contents through the dispensing aperture under a build-up of internal air pressure above the contents, within the container. Cessation of the applied manual pressure then terminates flow of the container contents, so that the container can be returned to an upright position, and the dispensing aperture recapped.
  • One of the main drawbacks of such prior art containers is the time delay required, subsequent to inverting the container, before dispensing can actually take place, during which time the viscid contents are required to flow from one end of the container to the other under the influence of gravity, or else the air contents initially located above the product transfers as a bubble, to the upper side of the product, on inversion of the container.
  • the delay is inconvenient., and can encourage users to shake the container in order to accelerate the contents reversal, sometimes with unpleasant results such as contents spillage or uncontrolled expulsion.
  • the container lip can become fouled with the product.
  • the container contents that become deposited on the screw cap or lid inner surfaces and in the container thread bands are difficult and time consuming to remove, and become stale and oxidized, and in the case of some products, become unpleasantly odorous. All of the contents cannot be readily dispensed, with consequent wastage, upon disposal of the container.
  • invertable containers having enlarged closure caps with flat heads, upon which the container can be stood in an inverted position
  • such containers are known for use with hand creams, hair shampoos and conditioners, and in the case of the PEARL DROPS product, with a dentifice.
  • These containers generally may be stood in an upright or in an inverted position. Reversal of the container to an upright position substantially negates the benefits of inverted storage.
  • closure caps of these prior dispensers require to be removed in order for the product to be dispensed. Being screw caps, this requires the unscrewing of the cap, which frequently impells the user instinctively to return the container to an upright position, thus sacrificing much of the benefits of container inversion.
  • the screw cap closures are inconvenient to access in the inverted condition, while there generally is difficulty in viewing the progress of the initial flow of the contents during dispensing.
  • a handheld, free standing container for the selective dispensing of product, wherein the container is permanently inverted, having an access in air sealing relation located on a lower side face of the container over which the contents dispose themselves, under the influence of gravity.
  • the present invention thus provides a free standing compressible container for the selective manual dispensing of fluent contents, comprising a manually squeezable enclosure having main walls sealingly engaged to front and rear side walls converging upwardly to a curvate top portion, a first bottom wall inclining upwardly and forwardly having an aperture for the passage of fluent contents therethrough, sealingly engaged to the front side wall, and a second bottom wall inclining upwardly and rearwardly, sealingly engaged to the first bottom wall immediately beneath the aperture and sealingly engaged to a lower edge of the rear side wall; and a heel portion affixed to the enclosure having a base, a rear wall and main walls, the walls of the heel portion being aligned with and supporting the walls of the enclosure such that when the container stands on the base of the heel portion the enclosure is supported in a free standing position.
  • the present invention further provides a valve means for use with a pressurizable container, comprising : collar attachment means for securing the valve means to an aperture in the container; apertured closure means providing an outlet aperture of limited cross sectional area; deflectable valve means normally extending in a first position in sealing relation across said outlet aperture, and movable away from the outlet aperture to a second, open position in response to pressure within the outlet aperture acting on the valve means.
  • Valve means are provided for the passage of contents from the container in dispensed relation therethrough.
  • the preferred container embodiment incorporates an air venting valve means, for admitting atmospheric air within the container subsequent to the dispensing of product therefrom.
  • an air venting valve means for admitting atmospheric air within the container subsequent to the dispensing of product therefrom.
  • the walls Upon release of the container walls from a laterally compressed condition, subsequent to dispensing product, the walls return to their original shape and induce a flow of air inwardly through the venting valve, into the container.
  • air in-flow is induced by the elastic condition of the container walls, which are expanded outwardly as a consequence of the "memory" of the plastic, subsequent to having been squeezed inwardly in a product dispensing operation.
  • the increase in internal volume induces air to fill the space, substantially to atmospheric pressure.
  • the present invention provides a handholdable, disposable dispensing container for the dispensing of fluent material, having a base portion, to support the container in free standing relation so that the material is concentrated by gravity, at the lower end hand squeezable wall portions, and a valved outlet at a lower portion of the container, normally submerged beneath the surface of the contents of the container, in use to facilitate downward dispensing of the fluent contents
  • the upper wall portions of the preferred embodiment are so shaped to preclude free standing thereon of the container, to ensure storage of the container in free standing relation upon its base, so that the contents are predisposed for dispensing.
  • the preferred embodiment container is shaped to fit comfortably to the hand, for ready squeezing of the main walls within the grasping hand.
  • the subject closure means in one embodiment is removable.
  • the subject filler closure means constitutes a permanent portion of the container, in sealed relation therewith, generally being sealed to the container subsequent to the insertion of container contents therein.
  • valve means are provided for the access of air to the interior of the container. These air valve means function generally as a non-return valve, wherein a flow of air is induced into the interior of the container upon releasing of the container walls in mutual expanding relation, subsequent to a product dispensing operation
  • the subject container conveys a number of advantages over former prior art containers, such as: greatly enhanced convenience for dispensing product; improved dispensing control, including ready viewing of product as it emerges from the container; low cost, simple container construction; minimized disturbance of product, unless desired; minimal product wastage and contamination; optimized product recovery; and facilitated or inhibited container re-use.
  • certain further aspects of container construction can include: construction of container outer surfaces to preclude free standing storage other than in a desired container orientation, for readiness in dispensing; the provision of a see-through wall portion or area of the container, for viewing the level of contents in the container; location of the dispensing nozzle on a side underface of the container, possibly downwardly inclined at an angle such as 45° to afford a clear view of the dispensed material, while protecting the outlet zone by overhang of the adjacent container portions; the configuring of the internal base
  • SUBSTITUTE SHEET surface of the container to be inclined towards the container outlet at an angle of inclination, generally at least equal to the angle of repose of the most viscous fluid for which the container is intended to be used; the provision of a depending, supporting heel portion external to the container inclined interior base wall, to orientate and support the interior base surface at the desired angle of inclination, referred to above.
  • the supporting heel may comprise an external slip-on, a blow-molding with a seam permitting separation or be suitably welded or glued to the container.
  • Certain desired characteristics of the discharge valve means comprise: a resilient check valve, responsive to container internal pressure to permit passage of content outwardly therethrough; utilization of a simple, resilient cantilever closure possessing plastic memory; or an equivalent multi-arm suspension; being substantially self-closing on termination of container pressurization; closure means arranged to be substantially self-cleaning in regard to flow guide faces and valve seal surfaces; locking means provided to positively lock the closure means in sealing relation with the container; and
  • finger grip means to facilitate grasping of the locking means by a user.
