Definitions

  • This invention relates to dispensing liquid products having a wide range of viscosities. More particularly, it concerns a dispenser of the pressurized propellant class that permits precise finger-tip control of the dispensing of even comparatively viscous products such as cremes fiowable gels and pastes including for example cosmetics or food products.
  • pressurized dispensing containers which have been commercially employed have been of the type in which the inner pressure has been maintained at some predetermined super-atmospheric level by the presence of pressurizing gas throughout the head space of the container.
  • this positive internal pressure is maintained throughout the useful life of the container by vaporization of liquefied propellant in the c ntainer or, in the case of non-liquefied propellants, by employing an excess amount of propellant gas at the time of filling to insure sufficient pressure to completely empty the package.
  • a further disadvantage is present in the convenionally employed pressurized containers in which the propellant is in continual contact with the product to be dispensed.
  • the propellant may cause the product to foam, interfering with product appearance.
  • the preferred embodiment comprises a dispenser which is at least as convenient to use as the pressurized propellant dispensers previously known, yet which is far safer to distribute and use and easier to make because it is not under continual internal pressure, but on the contrary is unpressurized at all times except during the few moments while the product is actually being dispensed.
  • a dispenser with a dispensing passage which may be large in cross section to permit the dispensing of even comparatively viscous products while yet avoiding the necessity of high internal pressures, to provide a fail-safe venting arrangement such that even the low pressure that does exist during the brief moments of actual product dispensing is safely vented should the user accidentally release his grip on the dispenser, to provide precise control of the amount of the product that is dispensed such that the product flow ends abruptly when the dispensing conrol is released by the user, and to provide such a container that may be manufactured economically preserving wide flexibility of choice both with respect to the composition of the product and propellant, and with respect to the size, shape material, and other characteristics of the product container.
  • the invention features an outer container for the product to be dispensed, a dispensing passage extending through a wall thereof, a propellant container having a valved opening within the outer product container, and a vent through the wall of the outer container.
  • the propellant container has a normally closed valve and a valve actuating mechanism that may be operated from the outside of the outer container by exerting an inward pressure upon flexible diaphragm forming a portion of the outer container wall.
  • a vent hole is provided at the center of the diaphragm so that the user may seal the vent with the same finger that he uses to press the diaphragm and thus to open the valve of the propellant container.
  • FIG. 1 is a perspective view of a preferred embodiment of the invention which may be used, for example, as a dispenser for a cosmetic creme.
  • FIG. 2 is a sectional plan view taken on a plane through the vertical axis of the dispenser.
  • FIG. 3 is a sectional view of the product container 2 taken on line 3-3 of FIG. 2.
  • FIG. 4 is a sectional plan view showing an alternative location 34 for the vent designated 30 in FIG. 1 and FIG. 2.
  • FIG. 5 is a sectional plan view showing a dispensing passage constructed as an integral part of the outer prod uct container 2 rather than as a separate dip-tube component 12 as shown in FIG. 2.
  • FIG. 6 is a sectional view of the product container 2 taken on line 6-6 of FIG. 5.
  • an outer product container 2 partially filled with the product 4.
  • a propellant space 6 is provided above the surface of the product 24 .
  • Propellant container 8 is supported within the outer product container, as for example, by flanges 10 which may be an integral part of the inner walls of the product container 2.
  • Dispensing passage 12 may also be formed as an integral part of the product container 2, for example as shown in FIG. 5, or alternatively, it may be a separately formed dip-tube assembly sealed to a suitable cooperating opening through the product container wall, for example as shown in FIG. 2.
  • Dispensing passage 12 extends between a product intake orifice 14, (preferably located at or near the lowest point of the product container to permit a maximum amount of the product to be dispensed) and product dispensing orifice 16 (which may if desired be provided with a removable cover or cap to protect product purity).
  • Propellant container 8 is initially charged with a com pressed or liquified gas or other suitably chosen propellant.
  • valve actuating mechanism 18 When valve actuating mechanism 18 is pushed downwards, the normally closed valve of propellant container 8 is opened, and the propellant gas is released through opening 20.
  • This gas can by-pass supporting flanges 10 through passages 22 (best seen in FIG. 3) and thereby fills propellant space 6, exerting pressure on the surface 24 of the product 4 and thereby forcing the product out through dispensing passage 12 at a predetermined rate.
  • This rate may be varied by suitable selection of the propellant characteristics, such as the vapor-pressure etc., by varying the shape and dimensions of dispensing pas sage 12, and by the structure of the propellant container valve, all of which are matters well known to those skilled in the art.)
  • Valve operating mechanism 18 is adjacent to the inner surface of flexible diaphragm 26 which is in turn hermetically sealed to product container 2 by sealing ring 28.
  • vent hole 30 which may be located directly above valve operating mechanism 18.
  • the vent hole may be located elsewhere on the surface of the outer product container 2, for example as shown in FIG. 4, FIG. 5, and FIG. 6 at 34. It is preferable that the vent hole 30 or 34 be located in such a position that it may be conveniently covered by a fingertip or other portion of the same hand of the user that (as later described) is used to actuate the valve operating mechanism 18.
  • valve operating mechanism 18 is grooved with a slot 32 which permits gas to pass freely between the outside and the inside of product container 2 whenever vent hole 30 is not covered from the outside.
  • the vent hole 34 communicates directly with one of the passages 22. Whatever the location chosen for the vent hole, it is necessary that when the vent is not sealed a free passage for gas should exist between propellant space 6 and the outer atmosphere.
  • the user presses a fingertip downwards on the center of flexible diaphragm 26 (at vent 30)), thereby sealing the vent and simultaneously deforming the diaphragm inwards thereby causing its inner surface to depress valve operating mechanism 18.
  • This opens the normally closed valve of propellant container 8 and thus causes propellant gas to be released through opening 20.
  • the propellant gas expands to fill gas space 6 and so exerts a predetermined pressure on the surface 24 of product 4. This pressure causes the product to flow out through dispensing orifice 16 of dispensing passage 12.
  • valve operating mechanism 18 is biased to return to its normally closed position when the flexible diaphragm is released by the used and no longer holds mechanism 18 in the open (depressed) position. Removal of the users finger from the diaphragm also uncovers vent hole 30. This permits rapid venting of the propellant gas from propellant space 6 to the outside of product container 2 thus equalizing the gas pressure inside the product container with the ambient atmospheric pressure and ensuring that no fur ther pressure is exerted on the surface of the product after the diaphragm is released by the user.
  • vent hole 34 may be covered by one digit of the users hand, and the diaphragm 26 may be pressed by another digit of the same hand. It may, for example, be convenient to press the diaphragm inwards with the ball of the thumb while vent hole 34 is sealed with the index finger as shown in FIG. 4.
  • the outer product container 2 is thus under pressure only during the brief time while the product is actually being dispensed. Should the dispenser be inadvertently dropped the vent 30 or 34 is automatically uncovered, rapidly venting the internal pressure of the container and so greatly reducing the hazard of flying fragments due to rupture of a container under pressure.
  • the product is not exposed to prolonged contact with the propellant; since this greatly reduces the problems of product foaming or product contamination by the propellant, a wider range of product and propellant combinations may be chosen without adverse effect.
  • the shape, size, material, and other characteristics of the outer product container may be freely selected in accordance with precise product requirements, rather than being subject to the severe safety constraints and other requirements related to the long continued presence of the propellant as in the case of previously constructed dispensers subject to continual pressure. Improved safety, economy and flexibility of design are some, but by no means all, of the significant advantages that arise from the described embodiment.
  • a dispenser comprising:
  • an outer container adapted to contain the product to be dispensed
  • a dispensing passage having an inlet orifice located within said outer container and extending through the wall of said outer container
  • a propellant container having a valve and a valve-operating mechanism operable from the outside of said outer container, said valve opening within said outer container,
  • a flexible diaphragm forming a portion of a wall of said outer container and adapted to cooperate with said valve operating mechanism
  • a closable vent comprising a hole adapted to be sealed by a portion of a users hand, extending through a wall of said outer container separate from said dispensing passage and adapted when open to permit.
  • vent and said diaphragm being positionally related to each other and exposed to the exterior of the dispenser to permit opening or closing of the vent simultaneously with actuation of the valve operating mechanism by a single hand of a user.
