Definitions
- This invention relates generally to a dispenser pouch adapted to contain a liquid therein and more particularly to a sealed pouch having a valve that is openable to dispense a pre-measured charge of liquid when external pressure is applied to the pouch.
- Dispensers for liquids having relatively high viscosities such as soap, shampoo, tomato ketchup, mayonnaise or the like, normally take the form of a semi-rigid plastic container having an openable closure cap or a reciprocal dispensing valve mounted thereon.
- Conventional dispensers of this type are relatively expensive to manufacture, prone to malfunction and normally do not insure that a pre-measured charge of the liquid will be dispensed therefrom.
- U.S. Patent No. 3,009,498 discloses a self-sealing valve for pouches or bags which purportedly exhibits critical ratios whereby the valve will close automatically to seal the bag after product has been dispensed therefrom.
- An object of this invention is to provide an improved and leak-proof dispenser pouch that is economical to manufacture and will repeatedly dispense pre-measured charges of liquid therefrom in a controlled manner.
- the dispenser pouch comprises a pair of panels defining a reservoir adapted to contain a liquid therein and spout means defined on a lower end of the pouch for retaining a pre-measured charge of the liquid prior to dispensing thereof.
- a normally closed valve means is defined at a lower end of the spout means and between the panels for opening to dispense the pre-measured charge of liquid in response to application of a predetermined level of external pressure on the pouch.
- Figures 1 and 2 illustrate a dispensing pouch 10 comprising a pair of superimposed front and rear panels 11 and 12, respectively.
- the pouch defines a reservoir 13 adapted to contain a liquid product therein, such as soap, shampoo, tomato ketchup, mayonnaise or other suitable product in liquid form.
- a liquid product such as soap, shampoo, tomato ketchup, mayonnaise or other suitable product in liquid form.
- the viscosity of the liquid product may range from that of water (1 centipoise) to that of a highly viscous liquid in the range of 1,000 centipoises.
- panels 11 and 12 constitute a pair of separate composite plastic sheets superimposed over each other during manufacture and heat-sealed together substantially about their peripheries as depicted at 14.
- An upper end 15 of the dispenser pouch is preferably left open during initial stages of the packaging process to fill the pouch with a liquid product 16 to the level shown in Figures 1 and 2. After filling the overlying panel portions at the upper end of the pouch are also heat-sealed together.
- a plurality of mounting holes 17 are formed through the pouch to adapt it for mounting purposes, as described more fully hereinafter.
- a lower end of the pouch is preferably closed by sealed panel portions forming a removable closure portion 18 that can be snipped-off by scissors, for example, when the dispenser pouch is placed into use by a consumer.
- each panel 11 and 12 is preferably composed of a cold extruded composite plastic material.
- each panel may comprise an outer layer 20 composed of polypropylene (e.g., 1.0 mil thick), an intermediate layer 21 composed of a standard cast Nylon "VI" material (eg, 1.25 mil (0.03175 mn) thickness) and an inner layer of polyethylene (eg, 5.0 mils (0.127 nm) thick).
- Individual thicknesses of the layers will vary depending on the particular consumer product application under consideration.
- the composite thickness of each panel 11 and 12 is preferably selected from the approximate range of from 5.0 mils to 10.0 mils for most applications of the home product type, adapted to contain from 100 ml to 1,000 ml of a liquid product in reservoir 13. Further, it is contemplated that most dispenser pouches of this type would have a total length in the approximate range of from 15.0 cm to 36.0 cm and an internal width of reservoir 13 (between heat seals 14 in Figure 1) of from 6.0 cm to 12.0 cm.
- dispenser pouch 10 further comprises a downwardly tapered neck or spout 23 terminating at its lower end at a valve 24, including a normally closed nozzle, canal or passage 25.
- Spout [25] 23 defines a charging chamber 26 therein communicating with reservoir 13 to receive and retain a pre-measured chaige of liquid 16.
- valve 24 (after removal of closure portion 18) will normally close passage 25 due to a "crimping" together of overlying and unattached portions of panels 11 and 12 defining the valve and passage.
- valve 24 When a predetermined level of external pressure is applied to reservoir 13, or preferably to charging chamber 26 directly by applying finger pressure thereto in a downward sliding movement of the fingers ( Figure 5), valve 24 will open to dispense the pre-measured charge of liquid from charging chamber 26 and through passage 25.
- each inner side defines an acute angle A relative to a centrally disposed longitudinal axis X of the pouch and spout, preferably selected from the range of from 45°to 80°. More preferably, the angle approximates 70°. If the angle is less than 45°, leakage may occur through passage 25 whereas if the angle exceeds 80°, charging chamber 26 may not empty fully when dispensing pressure is applied thereto ( Figure 5) .
- spout 23 is defined, in part, by inner sides 28 thereof that preferably taper downwardly in converging relationship relative to each other with each side defining an acute angle B relative to axis X.
- the latter angle is preferably selected from the range of from 8.5° to 16° and still more preferably at least closely approximates 11.5°. It has been found that an angle less than 8.5° will inhibit complete filling of charging chamber 26 with liquid and that an angle exceeding 16 0 may induce leakage through passage 25 without external pressure being applied to the dispenser pouch.
- dimension C depicts the approximate length of chamber 26 in the direction of axis X, i.e., the axial distance between an intersection I of axis X with an imaginary extension of an inner side 27 of reservoir 13 and the inlet to passage 25.
- Length C is preferably selected from the range of from 35 mm to 63 mm. This dimension, along with the width of chamber 26, will dictate the volume of the pre-measured charge of liquid (e.g., 1.0 ml) dispensed from chamber 26 and also defines the physical configuration of spout 23 to accommodate emptying of the chamber by finger pressure ( Figure 5) or mechanically induced pressure ( Figure 6). In many consumer applications under consideration, dimension C approximated 40 mm.
- Dimension D depicts the axial length of passage 25 and is preferably selected from the range of from 12 mm to 20 mm for dispenser pouches. having capacities in the range of from 100 ml to 1,000 ml. A passage length approximating 15 mm has been found to function satisfactorily for most product applications under consideration.
- Dimension E depicts the width of the passage and valve proper, transversely relative to axis X.
- This dimension is preferably selected from the range of from 2.3 mm to 5.5 mm. More preferably, this dimension closely approximates 4.2 mm in household type dispenser pouches of the type under consideration. It has been found that a passage width of less than 2.3 mm will require too high a compression pressure to open valve 24 for dispensing purposes whereas a width exceeding 5.5 mm will make the passage prone to leakage.
- the dispenser pouch is .particularly adapted for dispensing liquid soap, shampoo and cosmetic products in liquid form, having viscosities in the range of from 1 centipoise to 1,000 centipoise.
- pouch 10 can be: (1) Held by hand to dispense a liquid product therefrom, such as a dishwashing detergent or the like, (2) Hung from wall hooks by use of mounting holes 17 or hung from a shower rod or the like by a hook (not shown) to allow dispensing of the product by a single hand, or (3) Mounted in the type of combined holder and dispensing unit 29 illustrated in Figures 6 and 7. The latter unit adapts the pouch for mechanically induced dispensing pressure in a manner described hereinafter.
- Narrow passage 25 is held in a closed position to form valve 24 primarily due to the gravitational weight of the liquid product contained in reservoir 13 and communicating into charging chamber 26.
- the weight of the product and the resulting outward pressure imposed on overlying panels 11 and 12 in the area of spout 23, will tend to slightly stretch or flatten and compress the superimposed panel portions defining passage 25 together to thus form normally closed valve .24.
- Controlled product flow from chamber 26 through passage 25 will occur when the pressure applied to the pouch proper or preferably directly to the spout ( Figure 5) is greater than the pressure imposed on the spout to maintain the passage and valve closed, e.g., when a continuous and descending finger pressure approximating 15.0 psi is imposed on the spout in the manner illustrated in Figure 5.
- Combined holder and dispensing unit 29 of Figure 6 and 7 comprises a mounting bracket 30 adapted to be secured on a wall or the like by fastening means 31.

Abstract
Description
- This invention relates generally to a dispenser pouch adapted to contain a liquid therein and more particularly to a sealed pouch having a valve that is openable to dispense a pre-measured charge of liquid when external pressure is applied to the pouch.
- Dispensers for liquids having relatively high viscosities, such as soap, shampoo, tomato ketchup, mayonnaise or the like, normally take the form of a semi-rigid plastic container having an openable closure cap or a reciprocal dispensing valve mounted thereon. Conventional dispensers of this type are relatively expensive to manufacture, prone to malfunction and normally do not insure that a pre-measured charge of the liquid will be dispensed therefrom.
- Other types of conventional dispensers include thin-walled plastic pouches that are heat sealed to retain a liquid product therein. A corner of the pouch is either ripped open to dispense the product or a closure plug is used for this purpose. Further, U.S. Patent No. 3,009,498 discloses a self-sealing valve for pouches or bags which purportedly exhibits critical ratios whereby the valve will close automatically to seal the bag after product has been dispensed therefrom.
- An object of this invention is to provide an improved and leak-proof dispenser pouch that is economical to manufacture and will repeatedly dispense pre-measured charges of liquid therefrom in a controlled manner.
- The dispenser pouch comprises a pair of panels defining a reservoir adapted to contain a liquid therein and spout means defined on a lower end of the pouch for retaining a pre-measured charge of the liquid prior to dispensing thereof. A normally closed valve means is defined at a lower end of the spout means and between the panels for opening to dispense the pre-measured charge of liquid in response to application of a predetermined level of external pressure on the pouch.
- Other objects and advantages of this invention will become apparent from the following description and accompanying drawings wherein:
- Figure 1 is a partially sectioned front elevational view of a dispenser pouch embodying this invention;
- Figure 2 is a side elevational view of the dispenser pouch;
- Figure 3 illustrates design parameters for a spout and valve of the dispenser pouch;
- Figure 4 is an enlarged end view of the spout and valve, taken in the direction of arrows IV-IV in Figure 3;
- Figure 5 illustrates the application of finger pressure to the spout to dispense a pre-measured charge of liquid product from the dispenser pouch;
- Figure 6 is a sectioned side elevational view showing the dispenser pouch in phantom lines and mounted in a combined holder and dispensing unit therefor; and
- Figure 7 is a front elevational view of a mounting bracket of the holder and dispensing unit, take generally in the direction of arrows VII-VII in Figure 6.
- Figures 1 and 2 illustrate a dispensing
pouch 10 comprising a pair of superimposed front andrear panels 11 and 12, respectively. The pouch defines areservoir 13 adapted to contain a liquid product therein, such as soap, shampoo, tomato ketchup, mayonnaise or other suitable product in liquid form. The viscosity of the liquid product may range from that of water (1 centipoise) to that of a highly viscous liquid in the range of 1,000 centipoises. - In the preferred embodiment of this invention,
panels 11 and 12 constitute a pair of separate composite plastic sheets superimposed over each other during manufacture and heat-sealed together substantially about their peripheries as depicted at 14. Anupper end 15 of the dispenser pouch is preferably left open during initial stages of the packaging process to fill the pouch with aliquid product 16 to the level shown in Figures 1 and 2. After filling the overlying panel portions at the upper end of the pouch are also heat-sealed together. A plurality of mountingholes 17 are formed through the pouch to adapt it for mounting purposes, as described more fully hereinafter. A lower end of the pouch is preferably closed by sealed panel portions forming aremovable closure portion 18 that can be snipped-off by scissors, for example, when the dispenser pouch is placed into use by a consumer. - Referring briefly to Figure 4, each
panel 11 and 12 is preferably composed of a cold extruded composite plastic material. For example, each panel may comprise anouter layer 20 composed of polypropylene (e.g., 1.0 mil thick), anintermediate layer 21 composed of a standard cast Nylon "VI" material (eg, 1.25 mil (0.03175 mn) thickness) and an inner layer of polyethylene (eg, 5.0 mils (0.127 nm) thick). Individual thicknesses of the layers will vary depending on the particular consumer product application under consideration. The composite thickness of eachpanel 11 and 12 is preferably selected from the approximate range of from 5.0 mils to 10.0 mils for most applications of the home product type, adapted to contain from 100 ml to 1,000 ml of a liquid product inreservoir 13. Further, it is contemplated that most dispenser pouches of this type would have a total length in the approximate range of from 15.0 cm to 36.0 cm and an internal width of reservoir 13 (betweenheat seals 14 in Figure 1) of from 6.0 cm to 12.0 cm. - Referring to figures 1-3,
dispenser pouch 10 further comprises a downwardly tapered neck or spout 23 terminating at its lower end at avalve 24, including a normally closed nozzle, canal orpassage 25. Spout [25] 23 defines acharging chamber 26 therein communicating withreservoir 13 to receive and retain a pre-measured chaige ofliquid 16. When the pouch is filled, valve 24 (after removal of closure portion 18) will normally closepassage 25 due to a "crimping" together of overlying and unattached portions ofpanels 11 and 12 defining the valve and passage. When a predetermined level of external pressure is applied toreservoir 13, or preferably to chargingchamber 26 directly by applying finger pressure thereto in a downward sliding movement of the fingers (Figure 5),valve 24 will open to dispense the pre-measured charge of liquid fromcharging chamber 26 and throughpassage 25. - As shown in Figure 3, downwardly sloping and diverging
inner sides 27 of the pouch, defining the bottom ofreservoir 13, terminate at the upper extremity ofspout 23. Each inner side defines an acute angle A relative to a centrally disposed longitudinal axis X of the pouch and spout, preferably selected from the range of from 45°to 80°. More preferably, the angle approximates 70°. If the angle is less than 45°, leakage may occur throughpassage 25 whereas if the angle exceeds 80°,charging chamber 26 may not empty fully when dispensing pressure is applied thereto (Figure 5) . - Further,
spout 23 is defined, in part, byinner sides 28 thereof that preferably taper downwardly in converging relationship relative to each other with each side defining an acute angle B relative to axis X. The latter angle is preferably selected from the range of from 8.5° to 16° and still more preferably at least closely approximates 11.5°. It has been found that an angle less than 8.5° will inhibit complete filling ofcharging chamber 26 with liquid and that an angle exceeding 160 may induce leakage throughpassage 25 without external pressure being applied to the dispenser pouch. - As further shown in Figure 3, dimension C depicts the approximate length of
chamber 26 in the direction of axis X, i.e., the axial distance between an intersection I of axis X with an imaginary extension of aninner side 27 ofreservoir 13 and the inlet topassage 25. Length C is preferably selected from the range of from 35 mm to 63 mm. This dimension, along with the width ofchamber 26, will dictate the volume of the pre-measured charge of liquid (e.g., 1.0 ml) dispensed fromchamber 26 and also defines the physical configuration ofspout 23 to accommodate emptying of the chamber by finger pressure (Figure 5) or mechanically induced pressure (Figure 6). In many consumer applications under consideration, dimension C approximated 40 mm. - Dimension D depicts the axial length of
passage 25 and is preferably selected from the range of from 12 mm to 20 mm for dispenser pouches. having capacities in the range of from 100 ml to 1,000 ml. A passage length approximating 15 mm has been found to function satisfactorily for most product applications under consideration. - Dimension E depicts the width of the passage and valve proper, transversely relative to axis X. This dimension is preferably selected from the range of from 2.3 mm to 5.5 mm. More preferably, this dimension closely approximates 4.2 mm in household type dispenser pouches of the type under consideration. It has been found that a passage width of less than 2.3 mm will require too high a compression pressure to open
valve 24 for dispensing purposes whereas a width exceeding 5.5 mm will make the passage prone to leakage. - The dispenser pouch is .particularly adapted for dispensing liquid soap, shampoo and cosmetic products in liquid form, having viscosities in the range of from 1 centipoise to 1,000 centipoise. In use,
pouch 10 can be: (1) Held by hand to dispense a liquid product therefrom, such as a dishwashing detergent or the like, (2) Hung from wall hooks by use ofmounting holes 17 or hung from a shower rod or the like by a hook (not shown) to allow dispensing of the product by a single hand, or (3) Mounted in the type of combined holder and dispensingunit 29 illustrated in Figures 6 and 7. The latter unit adapts the pouch for mechanically induced dispensing pressure in a manner described hereinafter. -
Narrow passage 25 is held in a closed position to formvalve 24 primarily due to the gravitational weight of the liquid product contained inreservoir 13 and communicating intocharging chamber 26. In particular, the weight of the product and the resulting outward pressure imposed on overlyingpanels 11 and 12 in the area ofspout 23, will tend to slightly stretch or flatten and compress the superimposed panelportions defining passage 25 together to thus form normally closed valve .24. Controlled product flow fromchamber 26 throughpassage 25 will occur when the pressure applied to the pouch proper or preferably directly to the spout (Figure 5) is greater than the pressure imposed on the spout to maintain the passage and valve closed, e.g., when a continuous and descending finger pressure approximating 15.0 psi is imposed on the spout in the manner illustrated in Figure 5. - Combined holder and
dispensing unit 29 of Figure 6 and 7 comprises amounting bracket 30 adapted to be secured on a wall or the like byfastening means 31. Acover 32 is pivotally mounted on an upper end of the mounting bracket by a transversely disposedpin 33, secured inholes 34. A plurality ofmounting pins 35 are secured on the frontal side ofmounting bracket 30 to removably mountpouch 10 thereon by insertion of the mounting pins throughmounting holes 17. Aleaf spring 36 is secured in cantilevered relationship on a backside ofcover 32 and extends across the outer ends ofmounting pins 35 to normally bias the cover outwardly to its retracted position illustrated in Figure 6. - When
cover 32 is pushed down towardsmounting bracket 30 for dispensing purposes, a compression means 37 will function to compressspout 23 to openvalve 24 to dispense a pre-measured charge of liquid product frompouch 10. The compression means comprises acam member 38 pivotally mounted by apin 39 on an inner side ofcover 32. An upper end of the cam member is spring-biased into relatively "light" and non-dispensing contact with the pouch by acompression coil spring 40. - As shown in Figure 6, application of hand pressure to the cover, as depicted by an
arrow 41, will pivot and movecam member 38 from its solid line position to its phantom line position 38' for dispensing purposes. The motion of the cam member generally mimics the application of finger pressure to the pouch for dispensing purposes (Figure 5). Upon release of the cover, cantileveredleaf spring 36 will function to again retract the cover to its Figure 6 position to ready the unit for a subsequent dispensing function. - In general, the method for making
pouch 10 comprises cutting superimposed plastic sheets of the type described above to definepanels 11 and 12, having overlying body portions and spout portions. The panels are suitably heated and-' sealed together at peripheral portions 14 (Figure 1) to definereservoir 13 by the reservoir portions of the panels and spout 23 by the spout portions thereof. However, lower end portions of the spout portions of the panels are left unsealed to definepassage 25 which communicate withreservoir 13 in a manner described above. - Further,
upper end 15 of the pouch panels are not heat sealed together initially to adapt the pouch for filling withliquid 16. After the filling operation, the overlying panel portions at the upper end of the pouch are heat sealed together to fully seal the pouch, along withremoveable closure portion 18, defined at the outlet ofpassage 25. Mountingholes 17 may then be punched throughupper end 15 of the dispenser pouch, as illustrated in Figure 1.Pouch panels 11 and 12 may be heat-sealed together by the type of apparatus and method disclosed in U.S. Patent No. 4,545,844 with appropriate modification being made to the disclosed cutting and sealing dies to accommodate the configuration of the panels ofdispenser pouch 10.
