Definitions

  • ABSTRACT A valve for an aerosol container including a valve body having a number of fill orifices through which propellant and product may be more easily and more rapidly pressure filled.
  • the fill orifices are arranged on the valve body in spaced relation to the customary dispensing on the valve body.
  • Locking means may be fixedly or detachably mounted on the valve body in a predetermined spaced relation to the fill orifices in order to secure the customary dip tube thereto.
  • This invention is generally concerned with a valve body for an aerosol container which includes a plurality of orifices designed specifically for the filling of the aerosol container and locking means to secure the customary dip tube to the valve body to prevent disengagement of said tube during such filling.
  • Conventional aerosol dispensers generally comprise a pressurized container having a valve secured to the upper end thereof to control both the filling and discharge of the product. After the container has been filled and when not in use, the valve is biased to seal both the product and the propellant within the container.
  • a dip tube is normally attached to the valve body to extend downwardly to a point adjacent to the container bottom.
  • the container is generally filled with propellant or even product and propellant after the valve body is mounted thereon.
  • the valve is forced to its unsealed, discharge position and the propellant and/or product is forced to flow under pressure through the valve and into the container through the customary dispensing orifice, which serves as an expansion orifice, located on the valve body, and then through the dip tube.
  • Another object is to provide an aerosol dispenser which may be rapidly filled under pressure without disengagement of the dip tube from the valve body.
  • a further object is to provide an aerosol dispenser wherein the product and propellant mixture can enter the container under pressure other than through the dispensing orifice.
  • a still further object is to provide an aerosol dispenser wherein the container may be filled under pressure through a plurality of fill orifices arranged on the valve body in spaced relation to the dispensing orifice.
  • Another object is to provide a valve body having locking means arranged in predetermined relation to the fill orifices and serving to secure a dip tube to the valve body during pressurized filling of the container.
  • Another object is to provide a valve body for an aerosol dispenser having locking means detachably mounted thereon so as to secure a dip tube to the valve body during rapid, pressurized filling of the container.
  • This invention involves a valve body comprising a head portion and a depending tail portion of somewhat decreased diameter. At least one and preferably a number of fill orifices are fonned in the tail portion in intercommunicating relation between the interior of the valve body and the interior of the container. The fill orifices are arranged in spaced relation to a dispensing orifice through which the product is discharged from the container.
  • Locking means such as one or more anchoring rings, or a compression ring, or a frictional fit between the tail portion and an outer skirt, or combination thereof, are integrally or detachably mounted on the valve body to secure the dip tube to the tail portion.
  • These locking means are positioned with respect to the fill orifices to ensure that the dip tube remains attached to the valve body. The exact location of the fill orifices with respect to the locking means determines whether the product and propellant are directed into the container through the lower extremity or through the upper extremity of the dip tube for during pressurized filling, a part of the dip tube moves away from the fill orifices by the force of the expanding incoming product and propellant.
  • valve In use the valve with the dip tube secured thereto, is inserted into the open-mouth container which may or may not already have product therein. The valve is then sealed thereon generally by crimping. Propellant or a propellant-product mixture is then forced into the container through the valve body. It passes from the interior of the valve body, through the fill orifices, temporarily expanding the dip tube adjacent the fill orifices, into the dip tube and then into the container body. The aerosol dispenser is now ready for discharge of product.
  • the product Upon discharge, the product flows through the discharge orifice and cut through the valve stem in the conventional manner.
  • the pressure exerted by the propellant, causing discharge of the product is insufficient, within the valve body, to cause expansion of the dip tube from its sealing engagement with the fill orifices. Accordingly, the flow of product is in usual manner, i.e., through the dispensing orifice in the valve body so that proper expanding, prior to final exit, occurs.
  • FIG. 1 is a sectional view of an aerosol dispenser including a valve body secured to a dip tube and having fill orifices formed therein.
  • FIG. 2 is a sectional view of the valve body having the fill orifices located near the upper extremity of the dip tube.
  • FIG. 3 is a sectional view of the valve body having a depending skirt attachment.
  • FIG. 4 is a sectional view of the valve body having detachable locking means.
  • FIG. 5 is a sectional view of the valve body having the fill orifices angularly oriented relative to the valve body.
  • FIG. 1 illustrates a typical aerosol dispenser upon which the invention may be used.
  • the dispenser comprises container 10 having a closed bottom 12.
  • a mounting cup 14 is sealed to the container and has a valve, generally indicated as 16, attached thereto.
  • Valve 16 is secured within the central'turret portion of mounting cup 14 and includes a valve body 18.
  • the valve further includes a seal ring 20, a tubular valve stem 22 extending through ring 20 and a valve sealer 24.
  • the sealer 24 is forced into sealing engagement with ring 20 by valve spring 26.
  • the valve body 18 further comprises a head portion 28 and a depending tail portion 30 having a somewhat smaller diameter than head portion 28.
  • a dispensing orifice 32 is arranged in the bottom of tail portion 30. Dip tube 34 is secured to the tail portion 30 by an anchoring ring 36.
  • a plurality of fill orifices 38 are formed in the lateral wall of tail portion 30.
  • Each of the fill orifices is arranged in spaced relation to dispensing orifice 32 and is sealed by dip tube 34 when inoperative.
  • the surface 42 of dip tube 34 is forced away from sealing engagement with fill orifice 38.
  • Anchoring ring 36 prevents blow-off of the dip tube 34.
  • surface 42 resumes sealing engagement with fill orifices 38 and during discharge the pressure within valve body 18 is insufficient to overcome the natural bias of the tube and the pressure on the tube exterior. Hence, the fill orifices stay covered and sealed.
  • An additional aperture or vapor tap 44 is formed in the head portion 28.
  • the vapor tap serves to vent some gaseous propellant which normally accumulates in the top interior of container 10 into product being discharged. This provides better spray patterns.
  • FIG. 2 shows the fill orifices 38 arranged between the upper extremity 48 of dip tube 34 and anchoring ring 36.
  • the product enters the interior of tail portion 30. and forces the surface 42 of the upper extremity 48 of dip tube 34 outwardly. This in turn allows the passage of the product and propellant to pass through the fill orifices and over extremity 48 in the manner shown.
  • FIG. 3 involves a valve body 18 having an annular depending skirt 50.
  • Skirt 50 is preferably integrally formed with head 28 and is somewhat resilient.
  • the annular space 52 between the skirt and tail portion 30 is sufficient to accommodate the upper extremity 48 of dip tube 34 with sufficient friction to lock the dip tube to the tail.
  • one or more anchoring rings 36 may be formed on either or both (as shown) the inner surface 52 of skirt 50 or the outer surface of tail portion 30 which is surrounded by skirt 50.
  • FIG. 4 shows an alternate embodiment of skirted valve body 18.
  • the locking means comprises a detachable ring 54 mounted on the outer surface 56 of skirt 50.
  • Ring 54 is designed to compress skirt 50 about tail 30 in such a manner asto decrease the space 52 thereby grasping extremity 48 of dip tube 34.
  • the resiliency of skirt 50 may be increased by providing a slot 58.
  • FIG. 5 shows a variation in the shape of the fill orifices 38. Here they are arranged such that their axis are generally angularly inclined to the longitudinal axis of valve body 18. This structure minimizes fiuttering" of dip tube 34 during the pressurized filling of container whereby the locking means employed will remain secure. Accordingly, propellant and product may be filled at an even greater pressure thereby increasing the speed and efiiciency of filling a container.
  • valve 16 In the assembly and mounting of valve 16 in an aerosol container, no variation in standard technique is involved.
  • the valve after assembly, in standard fashion, is simply mounted in turret l4 and the turret is crimped to seal the valve in the open end of container 10.
  • container 10 is filled by any appropriate filling mechanism capable of cooperating with valve 16.
  • sealer 24 is forced down such that propellant and/or product may be forced into the interior of valve body 18. It enters the container primarily through fill orifices 38. In actual practice, a certain amount also flows into container 10 through discharge orifice 32.
  • fill orifice 38 While only two embodiments of fill orifice 38 have been shown (FIGS. 1 and 5), obviously other shapes to improve filling can be utilized.
  • the lower end of the dip tube may be vertically slotted with a fill orifice at the top of each slot. Similar variation may be made in the sealing means employed.
  • a split ring or an elastic band could be used on the lower extremity of the valve body rather than on the skirt.
  • a valve for an aerosol dispenser comprising: a valve body, at least one dispensing orifice formed in said valve body, said valve body including locking means for securing a dip tube to said valve body; at least one fill orifice formed on said valve body substantially larger than said dispensing orifice and normally sealed by said dip tube and said fill orifice arranged in spaced relation to said dispensing orifice, said locking means located on said valve body between said fill orifice and said dispensing orifice whereby said dispenser is primarily filled through said fill orifice during pressure filling by expansion of said dip tube in the area immediately adjacent said fill orifice.
