Definitions

  • the present invention relates to a valve for a pressurized dispensing container, and more particularly to a valve allowing for the release of pressure from a container to prevent over pressurization.
  • pressurized cans for dispensing products such as lotions and creams, for example, shaving cream.
  • these cans contain a chamber containing product, for example shaving cream, and a chamber of pressurized gas adapted to expel the product out of the container.
  • a container of this type with a pressurized gas subsequent to placing the product in the container.
  • a separate opening in the bottom of the container is utilized to introduce the propellant into the propellant chamber, and a plug or fill valve is thereafter quickly inserted to close the opening and maintain the pressure level of the propellant.
  • FIGS. 1-3 illustrate the use of this two-position fill valve.
  • the two-position fill valve initially is inserted into the container to a first position. This insertion typically is done at the facility where the container is manufactured. The container with the valve inserted then is transported to a filling facility. As shown in FIG. 1 , the flutes within the two-position fill valve provide an opening into the container. At the filling facility, the container is pressurized through the flutes, as shown in FIG. 2 . Thereafter, as shown in FIG. 3 , the valve is further inserted into the container to a second position where the valve seals the container.
  • a first aspect of a preferred embodiment of the present invention is a pressure control fill valve including a generally cylindrical body having a longitudinal axis, a first end, and a second end.
  • the body has a first section extending from said first end toward said second end and defining at least one circumferential groove.
  • the first section also defines at least one flute where the at least one flute defines a fill arc and a fill area when the pressure control fill valve is disposed in a dispensing container opening for filling the dispensing container and releasing pressure therefrom.
  • the body also includes a base defining a cavity, the cavity extending from the base inwardly toward the first end and a flexible wall disposed between the flute and the cavity that deforms upon the application of a suitable pressure to the first section of the body and reverts substantially to its original position upon a drop in pressure below the suitable pressure.
  • a second aspect of a preferred embodiment of the present invention is another pressure control fill valve including a generally cylindrical body having a longitudinal axis, a first end, and a second end.
  • the body has a first section extending from said first end toward said second end and defining at least one circumferential groove.
  • the first section also defines at least one flute where the at least one flute defines a fill arc and a fill area when the pressure control fill valve is disposed in a dispensing container opening for filling the dispensing container and releasing pressure therefrom, where the fill area is greater than 15.0% of the total area of the opening.
  • the body also includes a base defining a cavity, the cavity extending from the base inwardly toward the first end and a flexible wall disposed between the flute and the cavity that deforms upon the application of a suitable pressure to the first section of the body and reverts substantially to its original position upon a drop in pressure below the suitable pressure.
  • a third aspect of a preferred embodiment of the present invention is a dispensing container.
  • the container includes a container body including a propellant chamber and an opening for fluid communication with the propellant chamber and a pressure control fill valve disposed within the opening.
  • the pressure control fill valve is preferably capable of deforming to open the opening upon build up of a maximum pressure in the propellant chamber.
  • FIG. 1 illustrates a prior art two-position fill valve inserted in a first position in a dispensing container.
  • FIG. 2 illustrates the prior art two-position fill valve of FIG. 1 during charging of the dispensing container with pressurized gas while the two-position fill valve is in the first position.
  • FIG. 3 illustrates the prior art two-position fill valve of FIG. 1 within the container to seal the dispensing container following charging with the pressurized gas.
  • FIG. 4 is a perspective view of a fill valve according to one embodiment of the present technology.
  • FIG. 5 is a side cross sectional view of the fill valve of FIG. 4 , shown inserted in a container.
  • FIG. 6 is a perspective view of a fill valve according to another embodiment of the present technology.
  • FIG. 7 is a side cross sectional view of the fill valve of FIG. 6 , shown inserted in a container.
  • FIG. 8 is another perspective view of the fill valve of FIG. 6 .
  • FIG. 9A is a partial schematic cross sectional view of a container with the fill valve of FIG. 4 inserted in the bottom thereof.
  • FIG. 9B is a partial schematic cross sectional view of a container with the fill valve of FIG. 6 inserted in the bottom thereof.
  • FIGS. 4-8 two preferred embodiments of the present invention. These embodiments provide fill valves that prevent over pressurization of a dispensing container or canister by releasing pressure at a desired maximum point and then stopping the leakage of pressure at a desired minimum point.
  • FIGS. 4 and 5 show the first embodiment of a fill valve 10 in accordance with the present invention.
  • Fill valve 10 is preferably of unitary construction and formed from a deformable material, which, in a preferred embodiment may be nitrile. Other materials, however, can be utilized in constructing fill valve 10 such that fill valve 10 can be deformable for insertion into an opening of a pressurized can and exhibit the properties necessary to allow the aforementioned pressure release. This is discussed more fully below.
  • fill valve 10 has a generally cylindrical body about an axis X, a first end 12 , and a second end 14 .
  • Fill valve 10 is preferably adapted for insertion into a generally cylindrical opening in a pressurized dispensing container, in an insertion direction Y.
  • Fill valve 10 includes a first section 16 that includes a circumferential groove 18 , an outwardly extending lip 20 , two flutes 24 (one of which is seen in FIG. 4 ), and a wall 26 (shown in FIG. 5 ).
  • Valve 10 also includes a base 22 connected to or formed integral with first section 16 .
  • a cavity 28 is provided through base 22 and at least part of first section 16 .
  • first section 16 extends from first end 12 towards second end 14 , tapering outwardly along at least a portion of its length from a smaller diameter at first end 12 to a larger diameter where it meets base 22 .
  • First section 16 includes lip 20 , after which the diameter of first section 16 decreases to define circumferential groove 18 .
  • Circumferential groove 18 is essentially a ridged or shouldered section adapted for securing fill valve 10 within the opening of a dispensing container.
  • a second circumferential groove 30 is also provided in first section 16 , similar to groove 18 .
  • second circumferential groove 30 secures fill valve 10 in a first position within the opening of a dispensing container, thereby maintaining the position of fill valve 10 in the opening of the container during filling of the container.
  • first section 16 may include additional circumferential grooves or only one such circumferential groove.
  • Base 22 is preferably a substantially circular portion with a diameter greater than that of the first section 16 .
  • Base 22 can be any shape or size suitable for sealing the opening of a dispensing container.
  • Base 22 is preferably connected to first section 16 at or near circumferential groove 18 and can form a part of groove 18 . In operation, the wall of a container surrounding the fill opening is contained within circumferential groove 18 such that base section 22 seals the opening when fill valve 10 is fully seated.
  • Cavity 28 is preferably a cylindrical hole that extends from second end 14 through the interior of fill valve 10 towards first end 12 . Other shapes may also be employed. In a preferred embodiment cavity 28 does not extend all the way through first section 16 to first end 12 . Cavity 28 aids in the placement of fill valve 10 within a container and in the manipulation of fill valve 10 with respect to the container, allowing the release of pressure from inside the container.
  • Flutes 24 may include one flute, or a plurality of flutes, thereby promoting a more even and predictable collapse pressure.
  • Flutes 24 preferably define passages that are useful during a fill process and which allow pressure to escape when wall 26 deforms to slightly unseat fill valve 10 from a sealed position in the opening of a container.
  • the dimensions of flutes 24 are defined by the fill arc length and fill area 34 .
  • the fill arc length is defined as the total length of removed arcs 32 .
  • Fill area 34 is defined as the total area of the plane perpendicular to axis X surrounded by flutes 24 and the border of the opening of the container. Fill area 34 provides two passageways into the dispensing container for filling the dispensing container with pressurized gas or other material and releasing pressure upon over pressurization of the container.
  • wall 26 (best shown in FIG. 5 ) is disposed between flutes 24 and cavity 28 .
  • the thickness, and related stiffness, of wall 26 can be varied depending on the size and dimensions of cavity 28 .
  • wall 26 deforms, causing a temporary collapsing of first section 16 .
  • This collapse of first section 16 changes the orientation of circumferential groove 18 , allowing partial displacement of fill valve 10 within the opening of the container.
  • flutes 24 form a channel from the inside of the container to the outside of the container to release pressure from inside the container.
  • first section 16 has a diameter at first end 12 of approximately 0.183 inches and a diameter at lip 20 of approximately 0.260 inches.
  • Circumferential groove 18 has a diameter of approximately 0.240 inches.
  • Base 22 has a diameter of approximately 0.343 inches.
  • Cavity 28 has a diameter of approximately 0.127 inches. It is contemplated, however, that different sized and shaped fill valves can be utilized depending on the application, the canister, the fill hole size, etc. For example, an increase in the size of the container opening will facilitate the need for an increased sized fill valve 10 . Of course, the variation of one or more dimensions may require similar variations of others.
  • FIGS. 6-8 depict fill valve 100 in accordance with another embodiment of the present technology.
  • fill valve 100 is also a generally cylindrical body having a first end 112 and a second end 114 .
  • fill valve 100 includes a first section 116 which includes a circumferential groove 118 , an outwardly extending lip 120 , two flutes 124 defined by fill arc lengths and fill areas 134 , and a wall 126 .
  • a base 122 and a cavity 128 are also provided.
  • This second embodiment is substantially similar to fill valve 10 , however, it includes a larger cavity 128 .
  • Like reference numerals for like elements to those of the first embodiment have been utilized, but with a 100-series of numbers. Operation and use of valve 100 is also preferably substantially similar to that of valve 10 .
  • first section 116 of fill valve 100 has a diameter at first end 112 of approximately 0.183 inches and a diameter at lip 120 of approximately 0.260 inches.
  • Circumferential groove 118 has a diameter of approximately 0.240 inches.
  • Base 122 has a diameter of approximately 0.343 inches.
  • Cavity 128 has a diameter of approximately 0.160 inches. It is again contemplated that different sized and shaped fill valves can be utilized. For example, an increase in the size of the container opening will facilitate the need for an increased sized fill valve 100 .
  • Fill valves 10 and 100 provide an improved fill valve that prevents over pressurization of a dispensing container by releasing pressure at a desired maximum point and then stopping the leakage of pressure at a desired minimum point.
  • FIGS. 9A and 9B show the first and second embodiments, respectively, when inserted into the base of dispensing containers. While these embodiments are illustrative, it is contemplated that other embodiments may prevent over pressurization of dispensing containers by varying the profile, diameter, depth, or other pertinent features of the fill valve to accommodate different dispensing containers. Accordingly, the fill valve may be used with many different kinds of containers.
  • variations in the diameters of cavities 28 and 128 preferably results in a change in the thickness and/or stiffness of wall 126 , which necessarily adjusts the maximum pressure needed to deform wall 126 and temporarily collapse first section 116 .
  • Valves for use with containers openings of approximately 0.210 inches, and having cavities with diameters of 0.120 to 0.161 inches have been tested and shown to provide differing maximum pressure releases.
  • variations in the diameter of cavities 28 and 128 necessarily results in the changes of other element sizes, for similar overall sized valves. For example, as is noted above, such results in the change in thickness of wall 126 .
  • larger overall valve sizes may result in different cavity sizes now providing for different maximum pressures.
  • a valve designed for use with an opening larger than 0.210 inches may include a cavity having a diameter identical to that of cavity 28 .
  • the maximum pressure held by the larger valve may be greater than that of valve 10 .
  • this may vary.
  • valves in accordance with the present invention may vary the maximum pressure capable of being held by the particular valve.
  • identically sized and configured valves may hold different maximum pressures when one of the valves is constructed of a stronger or stiffer material.
  • the length of cavities in valves in accordance with the present invention may serve to vary the maximum pressure held by the valve in operation. For example, longer (or deeper) cavities may result in an overall reduction in material, which may make the valve weaker and subject to being deformed under lesser pressures.
