  • a container-in-container dispenser for dispensing a flowable product (e.g., a chemical product or food product) is generally indicated at reference numeral 10.
  • the dispenser 10 includes an outer container 12, and an inner container 14 (FIG. 3) received in the outer container.
  • the outer container 12 is pressurized with a propellant (e.g., gas, liquid) received in the interior of the outer container.

  • the dispenser 10 includes a hold-open device 18 received in the inner container 14.
  • the hold-open device 18, in one embodiment, is free-floating in the inner container 14, in that it is not attached to the valve 16 or the inner container, and is free in its entirety from attachment in the inner container. In other embodiments it may be attached to the valve 16 or other portion of the dispenser.
  • the outer container 12 may be generally rigid to maintain its shape and volume when pressurized with the propellant.
  • the outer container 12 may be formed from a suitable metal or plastic material having a suitable thickness.
  • the illustrated outer container 12 include a curl 20 (i.e. bead) to which the valve 16 and the inner container 14 may be secured, such as by crimping the valve on the curl so that a lip of the inner container is sandwiched between the curl and the valve.
  • the outer container 12 may be of other configurations and designs.
  • the inner container 14 is suitably collapsible (broadly, deformable) by pressure within the outer container 12 to decrease the internal volume of the inner container to expel the flowable product through the open valve.
  • the inner container 14 may be formed from a suitable metal or flexible plastic material having a suitable thickness.
  • the inner container 14 may be a collapsible pouch or bag.
  • the inner container 14 is suitable formed so that the inner container does not form tears or openings when collapsing.
  • the inner container 14 may be of other configurations and designs.
  • the illustrated valve 16 includes a mounting cup 24, a stem 26, and a seal (e.g., a grommet) 28, attached to the stem and disposed between and
  • valve 26 interconnecting the stem and the mounting cup.
  • the mounting cup 24 is suitable for attachment to the curl 20 of the outer container 12.
  • the valve 26 is in a closed (non-actuated) position.
  • the stem 26 is movable away from a seat portion of the seal 28 to open the valve 16 (e.g., move the valve to an actuated configuration) to allow flowable product in the inner container 14, via pressure in the outer container 12, to flow between the stem and the seat portion and into inlet(s) of the stem.
  • the valve 16 may function as a "vertically actuated” valve, or alternatively, as a “tilt” valve, depending on the actuator used to operate the valve.
  • valve 16 when used as a vertically actuated valve, an axial force is applied to the stem 26 to unseat the stem from the seat portion of the seal 28. In another example, when used as a tilt valve, a force is applied to the side of stem 26 to rotate or pivot the stem and unseat the stem from the seat portion of the seal 28, as is generally known in the art.
  • the valve 16 may be of other configurations and designs.
  • the hold-open device 18 includes an elongate body having opposite upper and lower longitudinal ends, a length extending between the upper and lower longitudinal ends, and a longitudinal axis LA extending along the length.
  • the elongate body includes a central hub 32 extending along the body, and a plurality of longitudinal ribs 34 extending radially outward from the hub relative to the longitudinal axis.
  • the hub 32 and the longitudinal ribs 34 extend continuously along the elongate body from the upper longitudinal end to the lower longitudinal end of the elongate body, although in other embodiments they may be discontinuous along the elongate body.
  • the hub 32 defines a longitudinal internal passage 38 extending longitudinally through the hub and through the upper and lower longitudinal ends of the elongate body.
  • the longitudinal ribs 34 are spaced apart from one another about the longitudinal axis LA to define a plurality of longitudinal external channels 40 extending along the elongate body and through the upper and lower longitudinal ends thereof.
  • the longitudinal external channels 40 are open at outer portions of the channels and closed at inner portions thereof.
  • the longitudinal internal passage 38 is defined by an interior surface of the elongate body, and the longitudinal external channels 40 are defined by an exterior surface of the elongate body.
  • the external channels 40 and the internal passage 38 substantially maintain the patency of the inner container 12 to improve the amount of product that is capable of being dispensed from the dispenser 10. It is understood that in other embodiments, longitudinal external channels may be formed in other ways.
  • the hold-open device 18 (e.g., the elongate body) is suitably flexible along its length so that the body is capable of deflecting (e.g., bending) as the inner container 14 collapses around and contacts the hold-open device.
  • the hold-open device 18 may bend along its length and generally conform to the longitudinal deformation of the inner container.
  • the elongate body is generally non-compressible radially and longitudinally so that the patency of the longitudinal internal passage 38 and the external channels 40 along their respective lengths are maintained as the inner container 14 collapses around and contacts the hold-open device 18.
  • the hold-open device 18 reduces the "dead spaces" in the inner container 14 as the inner container collapses (e.g., folds upon itself). As shown in FIG. 7, it is likely that the flowable product will enter (e.g., is forced into) one or both of the internal passageway 38 and the external channels 40 as the inner container 14 collapses around the hold-open device.
  • the internal passageway 38 and/or one or more of the external channels 40 maintain fluid communication with the valve 16.
  • the illustrated hold-open device 18 may be an integrally formed, monolithic, once-piece component.
  • the hold-open device 18 may be formed from a plastic material, such as by extrusion or molding.
  • the hold-open device 18 may be formed from polypropylene, or high density polyethylene, or combinations thereof, or other materials.
  • the following table illustrates the results of three test runs of container-in- container dispensers, each including a hold-open device as illustrated in the present application.
  • the hold-open device was formed from high density polyethylene by extrusion.
  • Each of the dispensers was tested for the weight of product dispensed and remaining in the dispenser after each container is no longer dispensing product.
  • the below results show that the hold-open device of the present disclosure is capable of dispensing product comparable to a hold-open device that includes a metal spring.
