Definitions

  • prior aerosol type dispensers generally were operable only in an upright condition, otherwise premature exhaustion of the dispensing medium would result with a substantial loss of usable product which would remain indispensable in the container due to loss of dispensing pressure.
  • Prior dispensers also had other deficiencies such as temperature sensitivity, non-uniform dispensing pressure, limited shelf-life, unreliability, difficulty of manufacture and relatively high cost of manufacture.
  • the present invention provides a dispensing mechanism which overcomes the above-mentioned deficiencies of the prior art devices and provides additional novel features and advantages, and a wider range of uses, than were possible with devices used heretofore.
  • a pressurized dispensing container containing an expansible bag capable of being inflated to force out the product disposed in the container externally of the bag.
  • the bag is divided into a plurality of expansible chambers or compartments serially arranged and separated from each other by disruptable transverse partitions which are attached at each end on the bag wall and extend across the bag. These partitions separate the bag into a series of individual compartments which contain one component of a two-component gas generating mixture.
  • One compartment begins to generate pressure gas after a predetermined period of time through addition of a delaying agent to the one gas generating component.
  • the present invention overcomes the above- mentioned deficiencies and provides a dispensing container with novel features and advantages and a wider range of uses than the devices of the prior art.
  • Expulsion means for developing and maintaining relatively constant gaseous dispensing pressure in a container from which a product is to be dispensed, comprising an enclosed, fluid impermeable flexible plastic pouch disposed within the container, and having a pair of facing wall members.
  • a plurality of pocket members are disposed within the pouch in spaced relation to one another and affixed to the interior of one of said wall members.
  • a closure member is associated with the interior of the other wall member and releasably closes each of said pocket members.
  • Each pocket member contains a first component, e.g., sodium bicarbonate, of a two-component carbon dioxide gas generation mixture.
  • the second component e.g., citric acid solution
  • the second component e.g., citric acid solution
  • Starting delay means e.g., a rupturable or dissolvable capsule containing sodium bicarbonate and/or lithium carbonate is disposed within the pouch in contact with the second component for causing the initial generation of carbon dioxide gas after a prescribed period of time and each pocket member is sequentially severable from the closure member to thereby empty its contents into admixture with the second component to generate more gas as the pouch expands due to the dispensing of the product from the container.
  • Container 10 has a cylindrical body or sidewall 11, inwardly dished bottom 12 and bell- shaped top 13 in which is mounted a conventional spring loaded aerosol spray valve assembly 14.
  • Container 10 and its component parts just described can be fabricated from any suitable material such as thin gauge aluminum or other metal, or even plastic depending on the product to be dispensed and any governing safety specifications that might be involved.
  • Valve assembly 14 is also of conventional design having plunger and spray head 15 carrying spray orifice 16, suitably constructed of plastic, and internal parts (not shown) such as a spring, ball valve and mounting ring 17 and bottom intake member 18 which may be of metal and/or plastic consistent with the previously mentioned requirements.
  • liquid product 19 and expulsion assembly 20 which is the subject of the present invention and as will be seen generates and maintains gas pressure within container 10 to enable product 19 to be dispensed on demand.
  • barrier member 22 At the upper end 21 of the interior of cylindrical body 11 is a perforated or foraminous barrier member 22 having a plurality of holes 23 distributed throughout its surface. Also affixed to inner surface 24 of sidewall 11 and extending longitudinally there along is a perforate tube member 25 having a plurality of holes 26 at spaced positions around and along said tube member 25.
  • the function of barrier member 22 and tube member 25 is to insure trouble-free operation of the dispenser and prevent expulsion assembly 20, as it expands in the manner to be described, from blocking off or plugging the interior of the container either laterally/circumferentially or plug- 'ging off the valve bottom intake member 18.
  • Expulsion assembly as shown is disposed within container 10 without being attached or anchored to container 10, although it may, if desired be so connected.
  • Assembly 20 is comprised of generally rectangular envelope, bag or pouch 27 which is constructed of a flexible, fluid impermeable plastic such as, for example, polyethylene or polypropylene and may be fabricated from a sheet of plastic by folding it into overlaid halves which are then sealed or adhered by suitable means along their respective contacting side forming a first wall member 27a and a second wall member 27b of the pouch 27.
  • Bottom and top edges 28, 29, 30 respectively form a sealed enclosure as shown in Figs. 1-3 inclusive.
  • fluid impermeable flexible plastic sandwich or enfoldment 31 having a pair of facing sheets 32 , 33 releasably adhered to one another (see also Figs. 2 through 6) and permanently attached by suitable means such as heat sealed portions 35 to respective interior sides 27c, 27d of pouch halves 27a, 27b respectively.
  • One sheet 32 is a substantially flat and the other sheet 33 has a plurality of cup- shaped depressions, cavities or pocket members 34 disposed inwardly from one surface thereof at spaced positions and aligned generally longitudinally of said enfoldment 31 which in turn is similarly aligned with respect to said envelope 20 in a substantially longitudinal relationship as shown in Fig. 1.
  • Pocket members 34 are "lidded" or closed by sheet 32 to encapsulate within each pocket member 34 an aliquot of sodium bicarbonate 36 which may be either in the form of powder or a solution.
  • citric acid solution 37 In the interior of pouch 27 is citric acid solution 37.
  • starting means 38 which as shown in the form of a dissolvable capsule and contains an initial charge of sodium bicarbonate which, after a predetermined period of time after assembly of the pouch 27 in container 10, filling the container with product 19 and capping it with the top 13 and associated parts, capsule 38 dissolves and causes the sodium carbonate contained therein to mix with the citric acid solution 37 and generate the initial quantity of carbon dioxide gas, thereby expanding envelope or pouch 27 and providing dispensing pressure within container 10.
  • the pouch member 27 in one preferred embodiment is constructed of a three layer laminated film having a middle layer of Saran, the external layer of Mylar and the inside layer (interior of the pouch) being low density polyethylene, each of said layers being approximately 2.5 mils in thickness except for the saran layer, which is only deposited from a spray.
  • the characteristics required or desired in said pouch is that it be non-toxic, have sufficient mechanical strength and chemical stability, be heat sealable (to the sheets 32 and 33) and flexible but not appreciably elastic or stretchable.
  • Sheet 32 is fabricated from material which contacts the bag 27 and is of compatible plastic, e.g., polyethylene. In one preferred embodiment it has an overall thickness of about 4.5 mils and is a three layer sandwich of about 0.5 mil Mylar in the middle and about 2.0 mils low density polyethylene either side.
  • compatible plastic e.g., polyethylene.
  • it has an overall thickness of about 4.5 mils and is a three layer sandwich of about 0.5 mil Mylar in the middle and about 2.0 mils low density polyethylene either side.
  • Sheet 33 carrying the pocket members 34 is adapted for deep drawing and is in one preferred embodiment a laminated plastic having an exterior layer (the layer in contact with pouch 27) of low density polyethylene of from about 0.5 to about 20 mils thick and an interior layer (the other side) of polypropylene of from about 0.1 to about 3.75 mils thick or higher. It is to be understood that pocket members 34 and capsule 38 may carry the citric acid and solution 37 may be sodium bicarbonate and water, or the two carbon dioxide generating components can be switched the other way around.
  • a typical formulation is for each pocket members 34 and the capsule 38 to be charged with about 1 gram each of a 50% citric acid solution and the envelope content 37 to be about 5 to 10 grams of sodium bicarbonate mixed with about 5 grams of water.
  • the pressure generated within container 10 is of the order of about 120 psig ⁇ 20% at an ambient temperature of about 70°F, but any desired pressure may be developed by adjusting the stoichiometry of the particular gas-generating ingredients.
  • sodium bicarbonate and citric acid are normally preferred, it is possible that under particular circumstances other materials may be more suitable such as, for example, dilute hydrochloric acid (e.g., 10-30% even up to about 35%) in place of the citric acid, and lithium carbonate or calcium carbonate in place of the sodium bicarbonate.
  • Sheet 33 is formed in a mold by heating and drawing to form pocket members 34.
  • the pocket members are then filled with one component, e.g., citric acid.
  • Sheet 32 is overlayed on sheet 33 to close pocket members 34 and the sheets are heat sealed together (Fig. 5) and enfoldment 31 is inserted into the open end 39 of pouch or bag 27 (Fig. 7) and the two members 31 and 27 are heat sealed together at 35.
  • Sodium carbonate solution 37 and starting capsule 38 are added to pouch 27 and then upper edge 30 of pouch 27 is heat sealed to completely enclose the contents in pouch 27 (Fig. 8).
  • the expulsion means assembly 20 is then inserted into container 10 and product 19 added, barrier member 22 put into place, and top 13 affixed to container 10 (Fig. 10).
  • starting capsule 38 has dissolved, generating carbon dioxide gas
  • expanding pouch 27 and the dispenser is now ready for use (Fig. 11).
  • Figs. 3, 12 and 13 show schematically how expansion of pouch 27, to separate inner sides of which sheets 32, 33 are permanently attached, successively pulls apart portions of releasably adhered sheets 32, 33 to successively expose the contents of each pocket member 34 and deliver it into contact and admixture with other gas generating component 37 in the bottom of the pouch.
  • Figs. 14-17 depict variations in the arrangement of pocket members 34 and heat seals 35 as well as in configurations and relative dimensions of pouch 27 and enfoldment 31.
