  • the flow path comprises a first channel portion extending from the inlet portion in a first direction away from the storage portion, a second channel portion reversely directed with respect to the first channel portion, and a third channel portion reversely directed with respect to the second portion and terminating at a discharge outlet end
  • the inlet section being enlarged with respect to the first channel portion and substantially tapered from the storage portion toward the first channel portion
  • the pouch includes tear tab means intersecting the discharge spout at the discharge outlet end to open the spout thereby to permit squeeze-dispensing pressure on the sheets at the storage portion to force the contents within the storage

  • Figure 10 is a front view of another embodiment of a fluid dispenser pouch with a double serpentine outlet converging on a single outlet passageway
  • a known flexible liquid dispenser pouch 10 includes a storage container portion 12 and a serpentine spout 14 (Figure 1a) and 16 ( Figure 1b)
  • the pouch is formed by two sheets of flexible plastic sheet material in overlying position which are sealed to define the shape of the two portions 12 and 14, 16
  • spout 14 has a serpentine shape including a first channel portion which initially extends directly away from storage pouch portion 12, a second channel portion that is redirected back toward the storage portion, and a straight third channel portion directed away from the storage portion to the exterior edge of the pouch.
  • a pre-formed score 18 is located across the bottom edge of the third channel portion which, when torn off, opens the serpentine outlet for discharging liquid from the pouch.
  • FIG. 1 b shows the first channel portion 20 of serpentine spout 16 at a slight angle with respect to the longitudinal direction of the pouch.
  • a flexible pouch 30 comprising a pair of flexible plastic sheets in overlying relationship which are sealed along the inner solid lines to define the shape of the a storage compartment 32 and a serpentine outlet 34.
  • serpentine outlet 34 is shown divided by broken lines into several sections. These sections include an inlet or access section 38, a holding reservoir or area 40, a back pressure channel area 42, a turbo channel section 44 and an exit channel 46.
  • a pre-formed score 36 allows the end portion 38 to be torn from the pouch in order to open exit channel 46 for dispensing liquid from pouch 30.
  • serpentine spout structures disclosed herein comprise various different channel shapes, width and length and reverse angles These differences in channel configurations create preferred liquid flow and discharge characteristics depending on the application at hand.
  • the various serpentine channel portions will first be discussed followed by several non-limiting examples of serpentine outlets.
  • Entrance or inlet section 38 from storage area 32 forms the first part of serpentine outlet 34 and is the starting point in establishing the hydrodynamic flow characteristics of liquid discharge from pouch 30. It has been found that under the typical operating conditions of a flexible pouch, such as shown at 10 in Figures 1a and 1 b, with the limited width of the entry channel portion in outlets 14 and 16, when pressure is applied to the pouch the outlet can be blocked due to folding of the plastic sheet or film. It has further been observed that with this type of serpentine outlet, with the restricted inlet sections, if they become blocked or sealed upon squeezing the pouch, application of higher pressures in attempting to overcome the blocking actually results in the opposite effect, namely, the outlet spout seals more tightly by further folding or creasing of the flexible film.
  • Section 38 is very important for providing ease of product flow and discharge during use. In order to commence flow of the product upon squeezing the pouch, section 38 must easily open so as to fill with product and develop sufficient pressure to overcome the resistance of the narrower downstream pathway.
  • Section 40 of the serpentine outlet functions as an interim holding reservoir and a measuring compartment which determines the metered amount of liquid that can be dispensed by a user applying hand pressure in the form of a short burst.
  • section 40 proper dimensions are required depending on the liquid being dispensed in order to ensure suitable quantities of the liquid are dispensed during use.
  • section 42 of the serpentine outlet Due to the desirability of using a serpentine outlet for a range of liquids which may have a wide variation of viscosities, the inventor has found that greater control is needed in the design of section 42 of the serpentine outlet.
  • the forward hydrostatic pressure developed in section 42 when a user has pressurized the pouch container portion 32 must be sufficient to overcome the back pressure in order to effect product flow and acceleration into sections 44 and 46 of the outlet passageway.
  • the reverse angle a- has also been found to exert an important influence on the flow characteristics of the serpentine channel. This angle, along with the viscosity of the liquid in pouch 30, determines, in part, how much pressure must be applied to the pouch to dispense the liquid therefrom.
  • the type of material being dispensed from pouch 30 will determine in part the preferred reverse angle ⁇ 1 of the outlet passageway. Specifically, it has been found that when angle ⁇ , exceeds 90° the back pressure generated in section 42 of the outlet passageway when the pressure on the pouch is released is insufficient to prevent leakage. It has been found that ⁇ 1 should be maintained in the range from about 180° (flow in opposite direction) to about 90° in order to generate sufficient back pressure to prevent leakage. Increasing the width of channel section 42 acts to reduce the channel pressure in the downstream section 44. Therefore, a combination of the angle ⁇ ,, width of section 42 and the degree of taper in this section, provides significant control over the back pressure generated in the outlet passageway.
  • Section 44 of the serpentine passageway is referred to as the turbo channel and the taper and angle of the bend of this portion of the outlet contributes in part, along with the fluid pressure in sections 38, 40 and 42, to determine the acceleration and hydrostatic pressure of the liquid entering section 46 as the pouch is pressurized. Conversely, when the pressure is released a braking action occurs so that the liquid in this portion of the channel stops flowing which stops liquid flow in either direction from the outlet, preventing liquid in the serpentine outlet back-flowing into the holding chamber
  • Section 44 of the serpentine outlet provides a channel lock.
  • the reverse angle ⁇ 2 in this section plays an important role.
  • the turbo channel section 44 is the bridge between the pressure reservoir section 42 and the exit channel 46. Depending on the taper and angle ⁇ 2 of the turbo section, the acceleration and hydrostatic pressure toward the exit channel 46 can be controlled
  • turbo channel section 44 is strongly affected by both the channel width and the second reverse angle ⁇ 2 but the inventor has discovered that variation in the width of channel section 44 has a more pronounced affect on function than the reverse angle A more restrictive channel width creates greater turbo channel pressures leading into channel section 46
  • section 46 of the serpentine outlet passageway controls the discharge behaviour of the expelled liquid from the dispenser pouch
  • Section 46 is preferably designed to avoid uncontrolled splashing or spattering of the liquid and to give the desired fluid expulsion rate from the pouch, which is dependent upon several factors including inherent properties of the fluid such as viscosity and external factors such as application pressure on the liquid being discharged
  • the design of the exit section 46 can aid in controlling the flow characteristics of the liquid being expelled by increasing or decreasing the speed at which the product is evacuated
  • the storage portion of the pouch includes a pair of opposed indentations 35 protruding into the interior of the pouch These pinch points help to stabilize the liquid filled pouch when it is squeezed and this feature cooperates with enlargement 38 to assist in smooth flow to the enlarged inlet opening 38
  • Figures 4a to 4c are front views of a series of serpentine spout outlets constructed in accordance with the present invention.
  • FIGS 4a to 4c there are shown a series of serpentine spout outlets 50, 52 and 54, respectively Spout 50 in Figure 4a is adapted for dispensing very low viscosity fluids such as water, tea, alcohols, and low viscosity pharmaceuticals such as saline solutions and the like
  • Outlet passageway 56 is tapered or narrows toward the discharge outlet of the passageway which is very advantageous when discharging low viscosity fluids since the tapered passageway acts to provide a faster discharge rate at a higher pressure than for a spout having a straight outlet passageway in the third segment of the serpentine outlet
  • Spout 52 in Figure 4b is characterized by an outlet or exit passageway 58 having an increasing taper or flare towards the discharge outlet which is very advantageous for discharging liquids having higher viscosities than used for spout 50 where spreading of the discharged product is desired
  • Spout 52 is adapted for use with, for example, sauces, cooking oils and oil based lubricants to mention just a few
  • Spout 54 in Figure 4c is adapted for use with fluids characterized by medium to high viscosities including soaps, cleaning gels, pastes, shampoos and creams
  • spout 64 is provided with an outlet passageway 68 narrower than passageway section 66 which is adapted for use with low viscosity pharmaceutical fluids such as eye drops, rubbing compounds, cough drops and the like where a greater discharge rate is preferred but not as rapid as would be obtained with spout 50 in Figure 4a
  • Figure 5b illustrates a spout 70 comprising a middle passageway section 72 which tapers or narrows toward the outlet passageway 74
  • the spout outlet 70 shown in Figure 5b provides a bowl-shaped pathway portion 72 which stores a proportionately greater amount of liquid than some of the other spouts which is useful for example in providing larger doses when the container is squeezed
  • the narrowing or tapering of channel 72 from the first pathway portion towards the third pathway portion acts to slow the movement of fluid as it enters the turbo or elbow portion
  • Figure 5c illustrates a spout 78 adapted for dispensing medium to high viscosity liquids such as ketchup, mustard, household detergents, shower gels, fabric softeners and the like to mention just a few.
  • high viscosity liquids such as ketchup, mustard, household detergents, shower gels, fabric softeners and the like to mention just a few.
  • Figure 5d shows a spout 84 adapted for dispensing very viscous liquids such as motor oils, greases, polishes and waxes to give a few examples.
  • the exit passageways 80 and 86 respectively are shorter and wider than the spout outlets for dispensing the lower viscosity fluids such as in Figures 3a and 4a.
  • the second reverse angle ⁇ 2 is smaller than for the other spouts.
  • the more squared-off serpentine outlets of Figures 4a to 4d are more advantageous for discharging higher viscosity liquids than are the more rounded-off spouts of Figures 3a to 3c.
  • the reverse angles a ⁇ and ⁇ 2 (see Figure 2) in spouts 64, 70, 78 and 84 can be less than the corresponding reverse angles in spouts 50, 52 and 54 since the spouts used for dispensing the less viscous fluids require greater reverse angles for providing a lock once pressure is relieved on the pouch.
  • the spouts of Figures 4a to 4c are characterized by a more rounded shape than the spouts of Figures 5a to 5d, which are more squared-off in terms of the structure of the tortuous pathway. Fluid flow through the squared-off serpentine outlets requires less pressure applied to the pouch than for fluid flow through the rounded-off outlets for the same viscosity liquids.
  • the serpentine spouts of Figures 4a to 4c offer more resistance to liquid flow therethrough compared to the serpentine spouts of Figures 5a to 5d. This structural difference is useful in designing spouts requiring metered dispensing of liquids, for example on a drop- by-drop basis.
  • a pouch 102 provided with a serpentine outlet 104 having a series of preformed parallel score lines 106 to 114.
  • the pouch may be opened at any of these score lines so that opening along score line 106 gives the fastest discharge rate for low viscosity liquid while opening the pouch along 114 gives the slowest discharge rate.
  • a pouch at 140 comprising a liquid storage section 142 and a serpentine spout outlet section 144.
  • Serpentine spout 144 comprises an S-shaped outlet passageway having a first flow path 146 extending away from the bottom of a flared inlet portion 148, a second flow path 150 which provides fluid flow substantially 180° reversed relative to the flow direction in section 146.
  • the serpentine outlet includes a second 180° reversal or bend into a third flow channel 152 extending from channel 150.
  • This type of serpentine outlet is preferred for dispensing liquids on a drop by drop basis, such as eye drops.
  • the resistance to flow offered by the rounded shape of the flow pathway along with the two substantially 180° provide a drop by drop expulsion rate of fluid from the pouch.
  • Pouch 160 includes an enlarged inlet 162 from storage area 158 into a first passageway 164 having a reverse turn and which tapers down into a second passageway 166 having a reverse turn and merging with a third tapered passageway portion 168 which merges with narrow outlet passageway 170.
  • Pouch 160 is suitable for dispensing fluids such as oil, cream and the like by the operator squeezing with his or her full hand.
  • another embodiment of the serpentine- shaped spout is similar to Figure 8 but includes passageway 166 splitting into a plurality of parallel discharge passageways 172, 174, 176 and 178.
  • a flexible liquid dispenser pouch 180 comprises a liquid storage area 182 and a generally T-shaped abutment 184 which divides the lower part of the storage area into two pathways 186 and 188.
  • the two pathways merge into a tapered channel section 190 which acts to increase the liquid pressure as the liquid flows into an exit passageway 192.
  • the double channels 186 and 188 in pouch 180 provide a structure allowing high discharge pressure to be generated. This is particularly advantageous in applications where the pouch is being used as a grease gun for discharging grease into a fitting requiring a very robust discharge of the grease to penetrate the fitting.
