DETAILED DESCRIPTION
DETAILED DESCRIPTION
[0024] In general, the disclosure is directed to refillable dispensing systems and components thereof. The system may include one or more reusable or refillable product packages configured to dock with an automated refilling station. The automated filling station automatically mixes concentrated chemical product with a diluent and dispenses the resulting chemical product solution. The product package may include a fitment insert configured to mate with a docking connector at the automated refilling station. When the product package is docked with the filling station, cooperation of the docking connector and the fitment insert may allow air to exit the interior of the product package as the chemical product is dispensed into the product package. When chemical product is dispensed from the product package, the fitment insert may further allow air to enter the interior of the product package to prevent collapse of the product package walls. Fitment insert and docking connection may be further configured to eliminate residual product build-up after dispensing of the diluted chemical product solution into product package, thus enabling the product package to achieve a dry break from the filling station. Once removed from the docking connection, the example fitment insert provides a positive, closed seal for the product package that does not leak in any orientation under normal conditions.
[0025] FIG. 1A is a shows an example refillable dispensing system 100.
Refillable dispensing system 100 includes a filling station 110 and at least one product package 152.
In the examples described herein, product package 152 may be reusable or refillable.
Filling station 110 automatically mixes concentrated chemical product with a diluent and dispenses the resulting chemical product solution to product package 152. A
concentrate container 118 (see FIG. 1B) located within filling station 110 stores the chemical product concentrate. Filling station 110 is further connected to receive the diluent (such as water).
A mixing pump within the filling station (not shown) automatically draws an appropriate amount of chemical product concentrate from concentrate container 118 and mixes it with an appropriate amount of diluent to create a chemical product solution having a target concentration. In the case of hand soap concentrates, for example, the dilution ratio may be 5:1 (5 parts diluent to 1 part concentrate) or 10:1. However, it shall be understood that any dilution ratio may be used and that the disclosure is not limited in this respect.
Refillable dispensing system 100 includes a filling station 110 and at least one product package 152.
In the examples described herein, product package 152 may be reusable or refillable.
Filling station 110 automatically mixes concentrated chemical product with a diluent and dispenses the resulting chemical product solution to product package 152. A
concentrate container 118 (see FIG. 1B) located within filling station 110 stores the chemical product concentrate. Filling station 110 is further connected to receive the diluent (such as water).
A mixing pump within the filling station (not shown) automatically draws an appropriate amount of chemical product concentrate from concentrate container 118 and mixes it with an appropriate amount of diluent to create a chemical product solution having a target concentration. In the case of hand soap concentrates, for example, the dilution ratio may be 5:1 (5 parts diluent to 1 part concentrate) or 10:1. However, it shall be understood that any dilution ratio may be used and that the disclosure is not limited in this respect.
[0026] Example refillable dispensing system 100 may be used with any type of concentrated chemical product, including but not limited to hand cleansers, liquid soaps, lotions, gels, foams, shampoos, hand creams, sanitizers, disinfectants, foams, detergents, bleaches, cleaning agents, laundry products, dish washing products, etc. In other examples, system 100 may be used with any other type of chemical product.
[0027] Filling station 110 includes filling station housing 122, an actuator 112, and doors 120A and 120B. FIG. 1B shows the example filling station housing 122 of FIG.
1A with door 120B open. A window 116 permits a user to view the amount of concentrate remaining in concentrate container 118. A lock 116 permits a user to lock filling station housing 122 so as to ensure only authorized users have access to the interior of the filling station housing and to permit tampering. Opening of door 120B permits access to the interior of the filling station housing 122 so that concentrate container 118 may be replaced when it becomes empty or when dispensation of a different chemical product is desired. FIG. 1C shows the example filling station housing of FIG. 1A with door 120A
open. Opening of door 120A permits access to the interior of filling station housing 122 and access to an automated filling pump 115 and docking connector 300. When the fitment insert of a product package is mated to docking connector 300, actuation of actuator 112 causes automated filling pump 115 to automatically mix concentrated chemical product stored in concentrate container 118 with a diluent and dispenses the resulting chemical product solution into the product package through the fill port defined by the product package fitment insert.

[0028] Referring again to FIG. 1A, example product package 152 includes one or more sidewalls 155 forming an enclosed product package configured to contain a quantity of chemical product. Product package 152 further includes an input port defined by a neck 156 through which product package may be filled with chemical product and an output port 158A through which chemical product may be dispensed from the product package.
A fitment insert 200 fitted within the neck 156 of product package 152 is configured to form a sealed connection with a docking connector (see, e.g., FIG. 3) located within the filling station housing 122. Fitment insert 200 forms a fill port through which product package 152 may be refilled. Once removed from the docking connection, fitment insert 200 provides a positive seal for product package 152 that does not leak in any orientation under normal conditions. Fitment insert 200 and docking connection may be further configured to eliminate residual product build-up after dispensing of the solution into product package 152, thus enabling the product package 152 to achieve a dry break from the filling station after filling of the product package is completed.

Fitment insert 200 and docking connection may be further configured to eliminate residual product build-up after dispensing of the solution into product package 152, thus enabling the product package 152 to achieve a dry break from the filling station after filling of the product package is completed.
[0029] Product package 152 may be further connected to a pump 154 to permit the chemical product to be dispensed from product package 152. In the example of FIG. 1A, product package 152 and pump 154 are connected by virtue of mating threads 158A and 158B on product package 152 and pump 154, respectively. Product package 152 and pump 154 may in turn be loaded into a product dispenser, such as product dispenser 180 as shown in FIGS. 2A and 2B. Pump 154 may be configured to deliver any form of chemical product, for example, liquids, foams, gels, alcohol foams, etc. In some examples, the combination of pump 154 and product package 152 may provide up to 99% product evacuation of the product package 152 for a wide range of product viscosities and densities.
[0030] FIGS. 2A and 2B show an example dispenser 180 which may be used to dispense chemical product from a product package, such as product package 152. As shown in FIG. 2A, dispenser 180 includes a dispenser cover 182 and a push bar 184. FIG.
shows example dispenser 180 with the cover 182 and push bar 184 removed. Push bar 184, when actuated by a user, causes a dispense mechanism 188 to engage with pump 154 to result in dispensation of a discrete quantity of the chemical product as indicated by arrow 186. In other examples, a different type of manual actuator may be used in place of push bar 184. Alternatively, dispenser 180 may include a sensor that detects presence of a user's hands near the dispenser and automatically triggers an actuator to dispense a quantity of fluid in response to the detection.

Alternatively, dispenser 180 may include a sensor that detects presence of a user's hands near the dispenser and automatically triggers an actuator to dispense a quantity of fluid in response to the detection.
[0031] Hand care dispensers, such as example dispenser 180, are generally placed near sinks in kitchens, hospital rooms, restrooms, or other locations to facilitate hand washing by employees, members of the public, or other users. Depending upon the environment in which the dispenser is being used (e.g., a hospitality or restaurant location as opposed to a health care location), the type of fluid being dispensed, and/or the particular requirements of the organization or corporate entity, the desired amount of fluid product to be dispensed may differ. In some examples, pump 154 and/or dispenser 180 may be implemented as shown and described in U.S. Patent No. 8,851,331 to Pelkey et al., issued October 7, 2014, and U.S. Patent No. 8,991,655 to Pelkey, issued March 31, 2015, both of which are incorporated herein by reference in their entirety. However, it shall be understood that other pump and/or dispenser designs may also be used, and that the disclosure is not limited in this respect.
[0032] The combination of refill station 110, product package 152, fitment insert 200, and pump 154 results in a "closed-loop" refillable dispensing system in the sense there is no user contact with concentrated chemicals. The refilling station automatically provides the correct dilution ratio of the concentrated chemical product, and the sealed connection of the fitment insert and the docking connector greatly reduces, if not eliminates, worker exposure to harsh chemicals. Refillable dispensing system 100 may thus increase ease of use, worker safety, and accuracy in the preparation of diluted chemical solutions.
[0033] FIG. 3A is a cross-sectional diagram of an example fitment insert 200 mated with an example docking connector 300, and showing a check ball 212 in the open position with respect to a check ball sealing ring 216. Docking connector 300 may form the receiving connector of a filling station, such as filling station 110 as shown in FIG. 1.
Docking connector 300 includes a docking connector body 304, a fill probe 302, and a vent tab 306. Fitment insert 200 includes a fitment insert body 204 including a first bore 209 defining a fluid passage from a first side 201 of the fitment insert body to a second side 203 of the fitment insert body, the fitment insert body further including an interior wall 205 forming a circumferential ridge 223 around the interior of the fluid passage.
Docking connector 300 includes a docking connector body 304, a fill probe 302, and a vent tab 306. Fitment insert 200 includes a fitment insert body 204 including a first bore 209 defining a fluid passage from a first side 201 of the fitment insert body to a second side 203 of the fitment insert body, the fitment insert body further including an interior wall 205 forming a circumferential ridge 223 around the interior of the fluid passage.
[0034] Fitment insert body also includes a barb member 220, check ball 212, a spring 214, and a vent probe 208. Fitment insert body 204 further includes a plurality of fitment tabs 202 and a rim 203. Fitment insert body 200 further includes a docking seal 206, a ball seal 216 a vent probe seal 210 and a fitment rim seal 218. Barb member 220 is generally tubular in shape, includes a first end and a second end, and is configured to fit within the fluid passage of the fitment insert body 204 with the first end disposed toward the first side of the fluid passage, the barb member also includes a bore extending from the first end to the second end.
[0035] When inserted into a product package, such as product package 152 of FIG. 1, fitment insert body receives the neck 156 of product package 152 between rim 203 and fitment tabs 202. Fitment tabs 202 flex inwardly during insertion of fitment insert body 204 into the neck 156 of product package 152 and then release back once the neck 156 of product package 152 is fully received within the space defined by rim 203 and fitment tabs 202. Force exerted by fitment tabs 202 presses neck 156 of product package 152 against fitment rim sealing ring 218 to provide a seal between the fitment insert body 204 and neck 156 of product package 152.
[0036] Fitment insert body 200 and docking connector 300 cooperate to provide a closed-loop system in which chemical product may be delivered from, for example, refill station 110, to a product package such as product package 152 without exposing a user to harsh chemical concentrates. When fully docked, fill probe 302 of docking connector body 304 depresses check ball 212, allowing for product to flow into the product package as indicated by arrow 160. While the product package is docked, tabs 304 of docking connector body 304 depress vent probe 208 to allow entrapped air to leave the product package through a venting aperture 211. A docking seal 206 prevents product from leaking out between fitment insert body 204 and docking connector body 304.
Fill probe 302 is configured to depress check ball 212 from the first side 201 of the fitment insert body and move check ball 212 from the closed position with respect to seal 216 to the open position with respect to seal 216 when fitment insert 200 is mated with docking connector 300.
Fill probe 302 is configured to depress check ball 212 from the first side 201 of the fitment insert body and move check ball 212 from the closed position with respect to seal 216 to the open position with respect to seal 216 when fitment insert 200 is mated with docking connector 300.
[0037] In some examples, once the package is removed from docking connector 300, check ball 212 is biased to closed position with respect to the check ball seal 216. In the example of FIG. 3A, the biasing force is provided by spring 214 pushes check ball against ball sealing ring 216 (or simply check ball seal 216), forming a positive, leak-proof seal.
However, it shall be understood that other mechanisms for biasing the check ball may also be used, and that the disclosure is not limited in this respect. A user may carry, transport, or store the product package in any orientation without product leaving the package. To dispense the product, the user need not to open the container as it is a closed-loop system.
The contents of the product package are dispensed/evacuated during normal use within the respective dispenser unit.
However, it shall be understood that other mechanisms for biasing the check ball may also be used, and that the disclosure is not limited in this respect. A user may carry, transport, or store the product package in any orientation without product leaving the package. To dispense the product, the user need not to open the container as it is a closed-loop system.
The contents of the product package are dispensed/evacuated during normal use within the respective dispenser unit.
[0038] FIG. 3B is a cross-sectional diagram of an example fitment insert 200 showing the check ball 212 in the closed position with respect to a check ball sealing ring 216. Sealing ring 216 is seated in a groove defined by a top edge of barb 220 and an inside edge ridge formed by fitment insert body 204. When fitment insert 200 is not mated to docking connector 300, a force provided by spring 214 pushes check ball 212 upwardly and against sealing ring 216, creating a seal at the interface of the check ball 212 and sealing ring 216.
[0039] FIG. 3C is a perspective view of an example check ball sealing ring 216, and FIG.
3D is a magnified cross-sectional diagram of an example fitment insert 200 showing check ball 212 in the closed position with respect to the check ball sealing ring 216. Example sealing ring 216 is generally in the shape of a torus having a non-circular cross-section.
Sealing ring may be fabricated using, for example, an elastomeric material.
Sealing ring 216 has a non-circular cross-section including a flattened sealing surface 217, and fitment sealing surfaces 215A and 215B. Fitment sealing surfaces 215A and 215B are shaped to fit the geometry of an interior ridge 223 formed within longitudinal bore 209 of fitment insert body 204. In this way, sealing surface 217 of sealing ring 216 presented to check ball 212 in the closed position presents a relatively greater surface area for the sealing interface as compared to a sealing ring having a circular cross-section.

Fitment sealing surfaces 215A and 215B are shaped to fit the geometry of an interior ridge 223 formed within longitudinal bore 209 of fitment insert body 204. In this way, sealing surface 217 of sealing ring 216 presented to check ball 212 in the closed position presents a relatively greater surface area for the sealing interface as compared to a sealing ring having a circular cross-section.
[0040] Sealing ring 216 is seated in a groove defined by a top edge 221 of barb 220 and a lower surface of interior ridge 223 formed within a longitudinal bore 209 through fitment insert body 204. The longitudinal axis of the bore 209 of fitment insert body is generally aligned (e.g., co-linear) with the longitudinal bore 226 of barb 220 (see, e.g., FIG. 5B) when barb 220 is received within bore 209. When fitment insert 200 is not mated to docking connector 300, the force provided by spring 214 pushes check ball 212 upwardly and against sealing ring 216, creating a seal at the interface of the check ball 212 and the sealing ring 216. Again, due to the flattened sealing surface 217 of sealing ring 216, a relatively greater surface area is provided for the sealing interface between sealing ring 216 and check ball 212 as compared to a sealing ring having a circular cross-section.
[0041] FIG. 4 is a perspective view of a fitment insert barb 220. Barb 220 is sized to fit within fitment insert body 204. Barb 220 includes one or more guide rails 222, a barb tip 224, a longitudinal bore 226 and a spring seat 228. FIGS. 5A is an exploded view of an example barb 220, spring 214, ball 212, and ball seal 216 of an example fitment insert 300. FIG. 5B is a cross-sectional view showing an example barb 220, spring 214, ball 212, and ball seal 216 as they would be assembled within an example fitment insert 300.
Guide rails 222 are sized to guide movement of check ball 212 from a sealed position to an open position. An inner rim formed around the circumference of bore 226 forms a spring seat 228 that supports spring 214 within bore 226.
Guide rails 222 are sized to guide movement of check ball 212 from a sealed position to an open position. An inner rim formed around the circumference of bore 226 forms a spring seat 228 that supports spring 214 within bore 226.
[0042] FIGS. 6A-6C are cross-sectional diagrams illustrating a fitment insert in a closed position, an open position, and a vacuum relief position, respectively. In the closed position as shown in FIG. 6A, check ball 212 is held against ball seal 216 by the spring force provided by spring 214 (not shown in FIG. 6A for purposes of illustration). Once fitment insert body 204 is fully docked with docking connector body 304, fill probe 302 depresses check ball 212, causing it to move from the closed position shown in FIG. 6A to the open position as shown in FIG. 6B. In the open position, fluid is dispensed through the tip of fill probe 302, around check ball 212 and into the product package.
[0043] Once the product package is removed from the filling station, and thus the fitment insert body 204 is removed from the docking connector body 304, tension provided by spring 214 (not shown in FIGS. 6A-6C) pushes check ball 212 against ball seal 216, forming a tightly closure and preventing chemical product from leaving the product package through the fill port provided by the fitment insert 300. Product package may then be loaded into a chemical product dispenser, such as example dispenser 180 as shown in FIGS. 2A and 2B. When product is subsequently dispensed from the product package, such as by manual actuation of a push bar or automatic actuation by a motion or presence sensor, a partial vacuum within the product package is created due to the seal provided by the check ball 212 and seal 216 of fitment insert body 302. In some examples, however, the spring tension of spring 214 is designed to maintain equilibrium of the product package pressure during product dispense. For example, the spring tension may be such that the partial vacuum resulting from dispensation of the chemical product from the product package draws ball 212 away from the ball seal 216 enough to allow air to enter and prevent collapse of the product package, as shown in FIG. 6C.
[0044] In some examples, the tip of fill probe 302 may include a protruding rib 310 that depresses check ball 212 and separates check ball 212 from apertures 312 in the fill probe 302 from which chemical product solution is dispensed, as shown in FIGS. 6A-6C. The filling operation takes place below the sealing surface of the fitment insert (that is, below fitment-to-product package seal 216 and docking seal 206) so that residual build-up of product is mitigated. This may help to achieve a clean separation from docking connector 300 and fitment insert 200.
[0045] FIGS. 7 and 8 are top perspective and bottom perspective views, respectively, of a fitment insert 200 mated with a docking connector 300. As shown above with respect to FIG. 4, docking connector 300 may form the receiving connector of a filling station, such as filling station 110 as shown in FIG. 1. Docking connector 300 includes docking connector body 304, fill probe 302, and vent tab 306. Fitment insert 200 includes fitment insert body 204, barb 220, check ball 212, spring 214, and vent probe 208.
Fitment insert body 204 further includes a plurality of fitment tabs 202 and rim 203. Fitment insert body 200 further includes docking seal 206, ball seal 216, vent probe seal 210 and fitment rim seal 218.
Fitment insert body 204 further includes a plurality of fitment tabs 202 and rim 203. Fitment insert body 200 further includes docking seal 206, ball seal 216, vent probe seal 210 and fitment rim seal 218.
[0046] When inserted into a product package, such as product package 152 of FIG. 1, fitment insert body receives the neck 156 of product package 152 between rim 203 and fitment tabs 202. Fitment tabs 202 flex inwardly during insertion of fitment insert body 204 into neck 156 of product package 152 and release back once the neck 156 of product package 152 is fully received within the space defined by rim 203 and fitment tabs 202.
Force exerted by fitment tabs 202 presses neck 156 of product package 152 against fitment rim sealing ring 218 to provide a seal between the fitment insert body 204 and neck 156 of product package 152.
Force exerted by fitment tabs 202 presses neck 156 of product package 152 against fitment rim sealing ring 218 to provide a seal between the fitment insert body 204 and neck 156 of product package 152.
[0047] Fitment insert body 200 and docking connector 300 cooperate to provide a closed-loop system in which chemical product may be delivered from, for example, refill station 110, to a product package such as product package 152 without exposing a user to harsh chemical concentrates. When fully docked, fill probe 302 of docking connector body 304 depresses check ball 212, allowing for product to flow into the product package as indicated by arrow 160. A longitudinal bore 226 extending through barb 226 receives check ball 212. A spring 214 fits within bore 226 and is supported by spring seat 214.
Check ball 212 moves within guide rails 222 between a closed position (not docked) and an open (docked) position. Movement of the check ball 212 is resisted by spring 214.
Spring 214 is supported by spring seat 228 formed at the base of guide rails 222 around an inner circumference of barb 220.
Check ball 212 moves within guide rails 222 between a closed position (not docked) and an open (docked) position. Movement of the check ball 212 is resisted by spring 214.
Spring 214 is supported by spring seat 228 formed at the base of guide rails 222 around an inner circumference of barb 220.
[0048] Guide rails 222 maintain proper alignment of check ball 212, helping to prevent misalignment of the check ball 212 with respect to the seal 216. The top edge of barb 220 maintains constant positioning of ball seal 216 and helps prevent ball seal 216 from becoming dislodged.
[0049] Check ball 212 moves in a linear path along guide rails 222 depending on the forces acting on it. Once seated, spring 214 creates a positive seal between check ball 212 and 0-ring seal 216 until sufficient cracking pressure (provided by dispensation of the chemical product from the product package) breaks the seal.
[0050] While the product package is docked, tabs 304 of docking connector body depress vent probe tip 208A, causing vent probe 208 to move downwardly (as shown in FIGS. 7 and 8) This movement of vent probe 208 further results in vent probe shoulder 208B to move away from vent probe seal 210, thus allowing entrapped air to leave the product package while the product package is being filled. Docking seal 206 prevents the chemical product from leaking out between fitment insert body 204 and docking connector body 304.
[0051] Once the product package (and thus the fitment insert body 204) is removed from docking connector 300, force provided by spring 214 pushes check ball against ball seal 216, forming a positive, leak-proof seal. A user may carry, transport, or store the product package in any orientation without leakage of the chemical product.
[0052] Although specific example mechanisms to achieve the filling and venting functions, alternative methods may also be used, and the disclosure is not limited in this respect. For example, these functions may be accomplished using a combination valve, a duckbill valve, magnetic valves, a vented membrane, an EPDM ball, an umbrella valve, etc.

[0054] FIG. 10 is a bottom view of an example fitment insert 200. Visible in FIG. 10 are fitment insert body 204, locking tabs 202, vent probe base 208C, ball 212 and barb 220.
Product package 152 may be of any appropriate size to fit a variety of dispensing applications. For hand washing applications, for example, product package 152 may be offered in multiple sizes, such as 1250m1 (70 gram), 750m1 (40 gram), and/or any other appropriately sized bottles. In some examples, product package 152 is comprised of a lightweight 100% recyclable High Density Polyethylene (HDPE). For example, the product package may be formed utilizing a high density polyethylene resin with a density greater than 0.953 g/cc (per ASTM D1505). In some applications, the product package may incorporate a percentage (e.g., 25%) of reclaimed post-consumer resin (PCR). The product package design may be aimed at keeping a small footprint while maximizing fill volume. This may be accomplished by designing a low profile top finish and using the inner finish edge as a mechanism to affix the insert permanently via lock tabs. The product package, fitment insert and docking connection may be designed with tight tolerances and quality finish to help ensure that the system remains leak proof.

The product package, fitment insert and docking connection may be designed with tight tolerances and quality finish to help ensure that the system remains leak proof.
[0055] In some examples, the geometry and features of the product package may be designed to resist or prevent collapse during the evacuation of product. For example, chamfered corners may help control product package deformation and promote a better drop-impact resistance. In some examples, the cracking pressure of the check ball seal may be designed to break before the lightweight HDPE product package collapses.
[0056] In the example such as product package 152 as shown in FIG. IA, the threaded connectors 158A may be designed with a unique thread pitch to help ensure that the proper pump type having the matching thread pitch is mated with the product package.
[0057] Check ball sealing ring 216, as well as docking seal 206, fitment seal 218, and vent probe seals, may comprise an elastomeric material, such as EPDM rubber (ethylene propylene diene monomer (M-class) rubber). In some examples, the geometry of check ball sealing ring 216 is such that a flattened sealing surface is presented to the check ball 212, providing a relatively larger surface area for the sealing surface as compared to a sealing ring having a circular cross-section.
[0058] Check ball 212 may be either stainless steel (or other hard non-porous material) or may be elastomeric.
[0059] Spring 214 may be either metal or plastic. For example, the spring may be 300 series stainless steel or Hastelloy metal blends. The spring length may be optimized to provide the most leak-proof seal while still allowing the partial vacuum break the seal, thus allowing air to enter into the product package during dispensation of the chemical product and preventing collapse of the product package. In some examples, the spring free length measures approximately18mm. However, it shall be understood that the spring parameters may vary depending upon the particular application, and that the disclosure is not limited in this respect.
[0060] In some examples, factors that may be taken into account when choosing a spring and/or spring rate may include: the force required to depress check ball 212 should not be too high so as to facilitate ease of docking to a filling station and thus ease-of-filling; the spring should provide sufficient force to the check ball to provide a positive, leak-proof seal when in the closed position; the partial vacuum resulting from dispensation of the chemical product from the product package should be sufficient to overcome o break the spring force and draw the check ball away from the seal, thus allowing the fitment insert to equilibrate the product package. Allowing air back into the product package system may help to prevent the product package from collapsing when used with a non-vented product pump.
[0061] The example refillable dispensing system and the components described herein may provide several advantages. For example, the refillable dispensing system may help to reduce costs associated with chemical product dispensing. For example, concentrated formulations may provide enough product for multiple refills using concentrated packs.
Users may purchase a set of refillable product packages, and refill and reuse the same set for a longer period of time as compared to 1-time use containers. Concentrated formula may help to reduce storage space, which is a commodity in the janitorial rooms, closets, or carts. Concentrated formula may also help to reduce shipping costs, shipping frequency, packaging costs, and waste pick-up. For example, if a product package may be refilled and reused approximately 10 times, use of a refillable product package may reduce waste by up to 90% compared to 1-time use containers. Flexible product packages may be lighter than rigid hand care bottles. In some examples, the product package may comprise 100% recyclable material, and may last up to 1-year with heavy usage. In addition, users may "top off' a product package whenever it is convenient. This enables users to prepare for busy periods when they don't have the luxury of time to change out product packages.
In some examples, cooperation of the pump design and the bottle may result in over 99%
evacuation from the product package. This may result in providing more product to the users and less product to landfills.
