Definitions
- This invention relates to spray dispensers, and more particularly to aerosol spray dispensers for personal care products.
- Body sprays Spray dispensers containing personal care products that are applied topically are often referred to as "body sprays.” These body sprays may be used to spray individual selected areas of the body, such as the underarm or foot, or may be used to spray large areas of the body. Such body sprays are generally portable, and include an aerosol canister fitted with an actuator mechanism and spray nozzle at the top of the canister that the user operates to apply the product to the user's skin.
- the personal care product may include a wide variety of cosmetic and/or skin care ingredients including, for example, fragrances, deodorant agents, antiperspirant agents, botanicals, and moisturizers.
- FR 2335420 , US 3157317 and US 2002/0074349 disclose spray dispensers according to the preamble of claim 1. US 5531359 , FR 2705322 and US 4024988 show locking assemblies for aerosol spray actuators.
- the present invention features a spray dispenser according to claim 1.
- spray dispenser 10 includes a housing 12 having an upper end 11, a lower end 13 and a sidewall 15.
- Housing 12 defines an interior compartment dimensioned to hold a replaceable aerosol canister 30, shown in FIG 4 and described below.
- the housing 12 is small and compact, allowing it to be easily carried by the user in a pocket, briefcase, sportsbag, backpack or handbag, while also being of sufficient size to hold a canister having a desired volume.
- the dispenser 10 may have an overall length L of about 5 to 15 cm, preferably about 8 to 12 cm), and a maximum diameter D of about 1.3 to about 4.5 cm), more preferably about 2 to about 4 cm, most preferably about 2.5 to about 3.5 cm.
- the canister contained within the housing may have a volume of about 0.1 to 5 ounces (about 3 to 150 ml), preferably about 0.5 to 1.5 ounces (about 15 to 45 ml).
- the spray dispenser 10 is sized so that its entire length will fit in a user's hand, or in a user's pocket or small handbag. In this embodiment, it is preferred that the length be less than about 12 cm.
- the transparent element 24 may be the entire housing sidewall (i.e., 100% of the housing sidewall; e.g., where the entire housing sidewall is molded entirely of transparent plastic) or the transparent element may occupy as little as 5% of the housing sidewall.
- the transparent element will be about 10% to about 50% of the housing sidewall.
- the transparent element may be molded into the sidewall housing, more typically it will be a separate piece affixed or mounted to a similarly dimensioned cut-out 29.
- the term transparent is intended to include optical clarity ranging from clear to translucent, provided that the clarity is sufficient to permit a user to visually discern identifiable markings on a canister contained within the spray dispenser. Most preferably, transparent means optical clarity sufficient to enable a user to discern at least 12 point black letters (Times New Roman typeface font) on white paper pressed against the transparent element.
- a closure assembly 25 ( FIG 5 ) is mounted at the lower end 13 of the housing, which closure is adapted to be easily openable by a user to permit the user to easily insert or remove a replaceable aerosol canister 30 through a bottom opening 32 at the bottom end of the housing (see FIGS. 2A and 4 ).
- the closure assembly preferably comprises a door 26 mounted to the housing by a hinge 28.
- the door has an inwardly facing surface 31 ( Fig. 5 ) and an externally facing surface 33 ( Fig. 7 ) (when viewed in the closed position).
- the door 26 includes a latching mechanism, the operation of which will be discussed below.
- the spray dispenser is used in conjunction with a replaceable body spray aerosol canister 30, including a can 21, a dip tube (not shown), a valve (not shown) and a stem 133.
- the spray dispenser uses a mechanical break-up feature to achieve a hollow cone pattern with a spread or diameter of about 3.8 to about 6.4 cm measured 15.2 cm from the nozzle.
- a replaceable aerosol canister does not include a spray nozzle or actuator mechanism. Thus, the replaceable canister will not deliver its contents until inserted into a reusable spray dispenser as described herein.
- the replaceable aerosol canister includes a personal care composition.
- the personal care composition is formulated to be safe for topical application to human skin, and generally is suitable for spraying on clothing without damage to fabrics.
- the personal care composition may include a wide variety of cosmetic and/or skin care ingredients including, for example, fragrances, deodorant agents, antiperspirant agents, botanicals, vitamins, essential oils, skin conditioning ingredients, and other active and inactive ingredients suitable for topical application to skin.
- Suitable antiperspirant agents include aluminum salts, such as, for example, aluminum chlorohydrate.
- a suitable deodorant active is any agent that inhibits, suppresses, masks or neutralizes malodor.
- deodorant actives include triclosan, triclocarban, usnic acid salts, zinc phenolsulfonate, b-chloro-D-alanine, D-cycloserine, aminooxyacetic acid, cyclodextrin, sodium bicarbonate.
- the replaceable aerosol canister is part of a system or product line that comprises a plurality (i.e., two or more, preferably three to ten) of replaceable aerosol canisters that have different personal care compositions, such as, for example, different fragrances and/or performance or aesthetic characteristics (e.g., deodorant, moisturizing, freshening, soothing, earthy, citrus, floral, musk, etc.) and/or different external markings (e.g., words, colors, designs, etc.) on the canisters.
- different personal care compositions such as, for example, different fragrances and/or performance or aesthetic characteristics (e.g., deodorant, moisturizing, freshening, soothing, earthy, citrus, floral, musk, etc.) and/or different external markings (e.g., words, colors, designs, etc.) on the canisters.
- the closure assembly 25 includes a resilient member such as a leaf spring 34, mounted on an internally facing surface 31 of door 26 so that the resilient member is biased (or pressed) against the canister when the canister is inserted and the door is closed, thereby biasing the canister 30 against the actuator assembly 18, limiting movement of the canister during transport and use of the dispenser, and resisting the force created when the user depresses the actuator button.
- the resilient member also assists in springing open the door 26 when unlatched by the user, as described below.
- the leaf spring may be a plastic molded component that is formed integrally with door 26.
- the force generated by the resilient member is preferably sufficient to resist the actuation force of the actuator button when it is depressed by a user, which is generally in the range of 2 to 8 pounds (0.9 to 3.6 kg). It is also generally preferred that the force generated by the resilient member be sufficiently low so that the door can be closed relatively easily. For example, in some embodiments it is preferred that the closure force for the door, with a canister in the holder, be less than 5 kg, more preferably about 1 kg to about 3.5 kg.
- the resilient member may include any other suitable type of resilient material such as a resilient plastic or foam piece, coil spring, etc.
- the geometry and physical characteristics of the leaf spring can be selected to provide the spray holder with desired characteristics. For example, making the leaf spring thicker (assuming other factors are kept the same) will tend to make the spring stiffer and thus make the door more difficult to close and reduce the overall deflection of the leaf spring during spray actuation. Conversely, making the leaf spring thinner will tend to reduce the stiffness of the leaf spring, making it easier to close the door and increasing the overall deflection of the leaf spring during spray actuation. If a low door closure force is desired, but it is also desired to prevent full deflection of the leaf spring during spray actuation, positive stops 37 may be provided on the internally-facing surface 31 of the door, e.g., as shown in FIGS. 14 and 14A . When the canister is deflected downwards, it will come to rest on stops 37 prior to the leaf spring bottoming out.
- the closure assembly 25 includes a latch mechanism that holds the door 26 securely closed and allows the door to be easily opened and closed by a user by operation of a latch actuator 38 ( FIGS. 6 and 7 ).
- the latch mechanism includes a latch 40 that moves forward and back in the plane of the door. When the latch is in its extended position, as shown in FIG 6 , it engages a rim 42 of a lower portion 44 of the housing 12, preventing the door from opening.
- latch 40 is biased towards its extended position by integrally formed springs 46a and 46b.
- Springs 46a and 46b include relatively thin curved arms 48, molded into the at-rest extended position, and disc portions 50 which are configured to slide along radially extending planar surfaces 52.
- the user pushes the latch actuator 38, which is preferably located on an externally facing surface 33 of the door, in the direction of the arrow 53 ( FIG 7 ), i.e., towards the hinge 28 (arrow A, FIG 6 ).
- This causes the arms 48 to straighten out, sliding the disc portions 50 outwardly along the surfaces 52 and thereby pulling latch 40 to its retracted position.
- latch 40 When latch 40 is retracted it no longer engages rim 42 of the housing, allowing the closure assembly 25 to swing open. Opening of the door is aided by the compression force of the leaf spring (if a canister is within the holder), and also by a torsion spring 19 associated with hinge 28.
- the latch 40 When the user pushes the door closed, the latch 40 is pushed to its retracted position by the interaction of the rim 42 with the angled top surface 43 of latch 40.
- the angled surface 43 helps to force the latch into the open position when the door is being closed.
- the angled surface 43 contacts the rim 42, compressing the springs 46a and 46b of the latch mechanism and pushing the latch 40 into the closure assembly.
- the latch 40 passes the rim 42 it springs back into its normal, extended position, due to the biasing force of springs 46a and 46b. There is no need for the user to move the latch actuator 38 when closing the door.
- the closure assembly may be assembled in any other desired manner, for example using adhesives or heat or ultrasonic welding.
- the spray actuator assembly 18 is shown with the outer shell 18 removed.
- the spray actuator assembly 18 includes an actuator/nozzle member 49, and a locking member 51.
- the actuator/nozzle member 49 includes a manually depressible actuator button 20 and a spray nozzle 16, discussed above.
- Member 49 also defines a pair of notches 54 which are configured to locate and prevent rotational motion of the actuator/nozzle member 49.
- the locking member 51 is mounted to pivot with respect to the actuator/nozzle member 49.
- the actuator assembly is fixed in the housing 12, with the actuator button 20 protruding outwardly.
- the pivoting motion of the locking member is in a plane that is generally perpendicular to the long axis of the canister, about a pivot point 57 ( Fig. 12 ). Rotational movement of the locking member is guided by the pivot 57 and an opening 23 in the outer shell 17 of the spray actuator assembly 18.
- the locking member is pivoted by the user moving the handle portion 22, discussed above, back and forth radially.
- Moving the handle 22 along opening 23 in the direction of arrow 56 ( FIG. 9 ) moves the locking member 51 to the locked position, shown in FIGS. 11 and 13 .
- a protrusion 58 on the upper surface of the locking member engages a corresponding protrusion 60 on the lower surface of the rim of actuator button 20.
- This engagement prevents the actuator button 20 from being pressed down, thereby preventing actuation of the spray dispenser.
- Moving the handle portion in the opposite direction (away from arrow 56) causes the protrusion 58 to move into a hollow region of the actuator button, where it does not engage any corresponding portion of the button. As a result, in this position the actuator is unlocked and the actuator button can be depressed to actuate the spray.
- the housing 12 may include an upper portion 120, at its upper end 11, that has a flexible tab 122 configured to flex up and down (arrow A).
- Tab 122 includes a arcuate rib 124 that extends upward, toward locking member 51 of the spray actuator assembly 18 (omitted for clarity in FIG. 16 ).
- the locking member 51 includes a pair of arcuate grooves 126, having a radius of curvature that is substantially the same as that of the arcuate rib 124.
- grooves are positioned so that when the locking member 51 is in its locked position, the rib 124 engages one of the grooves 126, and when the locking member 51 is in its unlocked position the rib 124 engages the other groove 126.
- the camming action of the curved surfaces of the rib and groove causes the tab 122 to deflect downward, releasing the rib from the groove in which it was engaged.
- the actuator/nozzle member 49 also includes a lower surface that is configured to engage the stem of the canister.
- the lower surface includes a tapered frustro-conical portion 62 that engages the rim of stem 133. This tapered surface provides a good seal with the stem, preventing undesirable leaking of the aerosol composition into the interior of the housing.
- the frustro-conical portion 62 may include a thin layer of an elastomeric material 64, providing a resilient gasket between the rim of the stem and the lower surface of member 49.

- Referring to
FIG. 1 ,spray dispenser 10 includes ahousing 12 having anupper end 11, alower end 13 and asidewall 15.Housing 12 defines an interior compartment dimensioned to hold areplaceable aerosol canister 30, shown inFIG 4 and described below. Thehousing 12 is small and compact, allowing it to be easily carried by the user in a pocket, briefcase, sportsbag, backpack or handbag, while also being of sufficient size to hold a canister having a desired volume. For example, referring toFIG 3 , thedispenser 10 may have an overall length L of about 5 to 15 cm, preferably about 8 to 12 cm), and a maximum diameter D of about 1.3 to about 4.5 cm), more preferably about 2 to about 4 cm, most preferably about 2.5 to about 3.5 cm. In some implementations, the canister contained within the housing may have a volume of about 0.1 to 5 ounces (about 3 to 150 ml), preferably about 0.5 to 1.5 ounces (about 15 to 45 ml). In a preferred embodiment, thespray dispenser 10 is sized so that its entire length will fit in a user's hand, or in a user's pocket or small handbag. In this embodiment, it is preferred that the length be less than about 12 cm. -
Housing 12, near theupper end 11 thereof, includes a spray actuator assembly 18 (FIG 10 ).Spray actuator assembly 18, which will be discussed in detail below, includes anouter shell 17, aspray nozzle 16, anoutlet 14 inouter shell 17 for the spray nozzle, and a manuallydepressible actuator button 20 exposed at the surface of the dispenser to allow the user to depress the button and deliver a spray of liquid particles from the nozzle. The spray actuator assembly also includes an actuator lock, discussed below, having ahandle portion 22 which is exposed, through anelongated opening 23 in theouter shell 17, for manipulation by the user in a radial direction between locked and open positions. - The housing includes a
viewing window 27 insidewall 15 through which a user of the dispenser may view the type of replaceable aerosol canister (described below) that is positioned within the housing. The viewing window may be an open cut-out 29 in the sidewall. The open cut-out may be as little as 5% of the housing sidewall or it may be as large as 90% of the housing sidewall. Preferably the cut-out will be about 10% to about 50% of the housing sidewall. More preferably, the viewing window is atransparent element 24 of the sidewall, as shown inFIGS. 1-4 . Thetransparent element 24 may be the entire housing sidewall (i.e., 100% of the housing sidewall; e.g., where the entire housing sidewall is molded entirely of transparent plastic) or the transparent element may occupy as little as 5% of the housing sidewall. Preferably, the transparent element will be about 10% to about 50% of the housing sidewall. While the transparent element may be molded into the sidewall housing, more typically it will be a separate piece affixed or mounted to a similarly dimensioned cut-out 29. The term transparent is intended to include optical clarity ranging from clear to translucent, provided that the clarity is sufficient to permit a user to visually discern identifiable markings on a canister contained within the spray dispenser. Most preferably, transparent means optical clarity sufficient to enable a user to discern at least 12 point black letters (Times New Roman typeface font) on white paper pressed against the transparent element. - The viewing window is a particularly advantageous feature when the dispenser is part of a product line that includes a plurality (i.e., two or more, preferably three to ten) of replaceable body spray aerosol canisters that have different contents, such as, for example, different fragrances and/or performance or aesthetic characteristics (e.g., deodorant, moisturizing, freshening, earthy, citrus, floral, etc.) and/or different external markings (e.g., words, colors, designs, etc.) on the canisters. Thus, while the viewing window may be any desired size or shape, preferably it should be of sufficient size and shape to enable the user to see external markings (e.g., descriptive or identification markings) on the canister. Typically, the viewing window will have an area (i.e., a projected area) of about 1 cm2 to about 30 cm2, more typically about 3 cm2 to about 25 cm2.
- A closure assembly 25 (
FIG 5 ) is mounted at thelower end 13 of the housing, which closure is adapted to be easily openable by a user to permit the user to easily insert or remove areplaceable aerosol canister 30 through a bottom opening 32 at the bottom end of the housing (seeFIGS. 2A and4 ). The closure assembly preferably comprises adoor 26 mounted to the housing by ahinge 28. The door has an inwardly facing surface 31 (Fig. 5 ) and an externally facing surface 33 (Fig. 7 ) (when viewed in the closed position). Thedoor 26 includes a latching mechanism, the operation of which will be discussed below. Because the door is attached to the housing, there is no need for the user to hold the closure assembly in one hand while inserting the canister, as would be the case with a twist-on door. Of course, it is contemplated that the preferred door-type closure described above could be replaced with a different type of closure such as a twist-on cap or press-fit cap, provided that such a cap is equipped with a sufficient retention mechanism to keep it in place during storage and use. - The spray dispenser is used in conjunction with a replaceable body
spray aerosol canister 30, including acan 21, a dip tube (not shown), a valve (not shown) and astem 133. The spray dispenser uses a mechanical break-up feature to achieve a hollow cone pattern with a spread or diameter of about 3.8 to about 6.4 cm measured 15.2 cm from the nozzle. A replaceable aerosol canister (as used herein) does not include a spray nozzle or actuator mechanism. Thus, the replaceable canister will not deliver its contents until inserted into a reusable spray dispenser as described herein. - The replaceable aerosol canister includes a personal care composition. The personal care composition is formulated to be safe for topical application to human skin, and generally is suitable for spraying on clothing without damage to fabrics. The personal care composition may include a wide variety of cosmetic and/or skin care ingredients including, for example, fragrances, deodorant agents, antiperspirant agents, botanicals, vitamins, essential oils, skin conditioning ingredients, and other active and inactive ingredients suitable for topical application to skin. Suitable antiperspirant agents include aluminum salts, such as, for example, aluminum chlorohydrate. A suitable deodorant active is any agent that inhibits, suppresses, masks or neutralizes malodor. These may include (1) antimicrobial or bactericidal agents which kill the bacteria responsible for malodor production, (2) agents which inhibit or suppress or interfere with the bacterial enzymatic pathway that produces malodor, and (3) agents which mask or absorb or neutralize malodor. Fragrances are not considered deodorant active ingredients within the meaning of this application. Examples of deodorant actives include triclosan, triclocarban, usnic acid salts, zinc phenolsulfonate, b-chloro-D-alanine, D-cycloserine, aminooxyacetic acid, cyclodextrin, sodium bicarbonate.
- Preferably, the replaceable aerosol canister is part of a system or product line that comprises a plurality (i.e., two or more, preferably three to ten) of replaceable aerosol canisters that have different personal care compositions, such as, for example, different fragrances and/or performance or aesthetic characteristics (e.g., deodorant, moisturizing, freshening, soothing, earthy, citrus, floral, musk, etc.) and/or different external markings (e.g., words, colors, designs, etc.) on the canisters.
- Various preferred features of the
dispenser 10 will be discussed below. - As shown in
FIG 5 , theclosure assembly 25 includes a resilient member such as aleaf spring 34, mounted on an internally facingsurface 31 ofdoor 26 so that the resilient member is biased (or pressed) against the canister when the canister is inserted and the door is closed, thereby biasing thecanister 30 against theactuator assembly 18, limiting movement of the canister during transport and use of the dispenser, and resisting the force created when the user depresses the actuator button. The resilient member also assists in springing open thedoor 26 when unlatched by the user, as described below. When a leaf spring is used, as shown, the leaf spring may be a plastic molded component that is formed integrally withdoor 26. The force generated by the resilient member is preferably sufficient to resist the actuation force of the actuator button when it is depressed by a user, which is generally in the range of 2 to 8 pounds (0.9 to 3.6 kg). It is also generally preferred that the force generated by the resilient member be sufficiently low so that the door can be closed relatively easily. For example, in some embodiments it is preferred that the closure force for the door, with a canister in the holder, be less than 5 kg, more preferably about 1 kg to about 3.5 kg. Naturally, of course, the resilient member may include any other suitable type of resilient material such as a resilient plastic or foam piece, coil spring, etc. - The geometry and physical characteristics of the leaf spring can be selected to provide the spray holder with desired characteristics. For example, making the leaf spring thicker (assuming other factors are kept the same) will tend to make the spring stiffer and thus make the door more difficult to close and reduce the overall deflection of the leaf spring during spray actuation. Conversely, making the leaf spring thinner will tend to reduce the stiffness of the leaf spring, making it easier to close the door and increasing the overall deflection of the leaf spring during spray actuation. If a low door closure force is desired, but it is also desired to prevent full deflection of the leaf spring during spray actuation,
positive stops 37 may be provided on the internally-facingsurface 31 of the door, e.g., as shown inFIGS. 14 and 14A . When the canister is deflected downwards, it will come to rest onstops 37 prior to the leaf spring bottoming out. - The
closure assembly 25 includes a latch mechanism that holds thedoor 26 securely closed and allows the door to be easily opened and closed by a user by operation of a latch actuator 38 (FIGS. 6 and7 ). Referring toFIGS. 5 and6 , the latch mechanism includes alatch 40 that moves forward and back in the plane of the door. When the latch is in its extended position, as shown inFIG 6 , it engages arim 42 of alower portion 44 of thehousing 12, preventing the door from opening. Referring toFIG 8 , latch 40 is biased towards its extended position by integrally formedsprings Springs curved arms 48, molded into the at-rest extended position, anddisc portions 50 which are configured to slide along radially extendingplanar surfaces 52. - To open the door, the user pushes the
latch actuator 38, which is preferably located on an externally facingsurface 33 of the door, in the direction of the arrow 53 (FIG 7 ), i.e., towards the hinge 28 (arrow A,FIG 6 ). This causes thearms 48 to straighten out, sliding thedisc portions 50 outwardly along thesurfaces 52 and thereby pullinglatch 40 to its retracted position. Whenlatch 40 is retracted it no longer engagesrim 42 of the housing, allowing theclosure assembly 25 to swing open. Opening of the door is aided by the compression force of the leaf spring (if a canister is within the holder), and also by atorsion spring 19 associated withhinge 28. - When the user pushes the door closed, the
latch 40 is pushed to its retracted position by the interaction of therim 42 with the angledtop surface 43 oflatch 40. Theangled surface 43 helps to force the latch into the open position when the door is being closed. Theangled surface 43 contacts therim 42, compressing thesprings latch 40 into the closure assembly. As soon as thelatch 40 passes therim 42 it springs back into its normal, extended position, due to the biasing force ofsprings latch actuator 38 when closing the door. - The closure assembly may be manufactured in any desired manner. In some embodiments, the parts of the closure assembly may be snap fit together. For example, the parts may be assembled as illustrated by the series of
FIGS. 15-15B , in which alatch portion 102 is first assembled into adoor shell 100 which includes the leaf spring (FIGS. 15 and 15A , and then acover 106 is snap fit into the door shell 100 (FIG 15B ) by insertingprongs 106 carried by an inward-facing surface 105 of thecover 106 into receivingopenings 108 in thedoor shell 100.Prongs 106 are configured to deflect and spring back upon insertion so that the prongs will be permanently retained in the openings. Cover 106 includes anopening 110 through which thelatch actuator 38 extends when the closure assembly is fully assembled. - The closure assembly may be assembled in any other desired manner, for example using adhesives or heat or ultrasonic welding.
- Referring to
FIG 10 , thespray actuator assembly 18 is shown with theouter shell 18 removed. Thespray actuator assembly 18 includes an actuator/nozzle member 49, and a lockingmember 51. The actuator/nozzle member 49 includes a manuallydepressible actuator button 20 and aspray nozzle 16, discussed above.Member 49 also defines a pair ofnotches 54 which are configured to locate and prevent rotational motion of the actuator/nozzle member 49. - The locking
member 51 is mounted to pivot with respect to the actuator/nozzle member 49. The actuator assembly is fixed in thehousing 12, with theactuator button 20 protruding outwardly. The pivoting motion of the locking member is in a plane that is generally perpendicular to the long axis of the canister, about a pivot point 57 (Fig. 12 ). Rotational movement of the locking member is guided by thepivot 57 and anopening 23 in theouter shell 17 of thespray actuator assembly 18. - The locking member is pivoted by the user moving the
handle portion 22, discussed above, back and forth radially. Moving thehandle 22 along opening 23 in the direction of arrow 56 (FIG. 9 ) moves the lockingmember 51 to the locked position, shown inFIGS. 11 and13 . In this position, aprotrusion 58 on the upper surface of the locking member engages a correspondingprotrusion 60 on the lower surface of the rim ofactuator button 20. This engagement prevents theactuator button 20 from being pressed down, thereby preventing actuation of the spray dispenser. Moving the handle portion in the opposite direction (away from arrow 56) causes theprotrusion 58 to move into a hollow region of the actuator button, where it does not engage any corresponding portion of the button. As a result, in this position the actuator is unlocked and the actuator button can be depressed to actuate the spray. - If desired, positive stops may be provided for the two positions of the
handle portion 22, to give the user a tactile signal that locking/unlocking has been completed, and to prevent inadvertent locking and unlocking. For example, as shown inFIGS. 16 and17-17A , thehousing 12 may include anupper portion 120, at itsupper end 11, that has aflexible tab 122 configured to flex up and down (arrow A).Tab 122 includes aarcuate rib 124 that extends upward, toward lockingmember 51 of the spray actuator assembly 18 (omitted for clarity inFIG. 16 ). As shown inFIGS. 17-17A , the lockingmember 51 includes a pair ofarcuate grooves 126, having a radius of curvature that is substantially the same as that of thearcuate rib 124. These grooves are positioned so that when the lockingmember 51 is in its locked position, therib 124 engages one of thegrooves 126, and when the lockingmember 51 is in its unlocked position therib 124 engages theother groove 126. When thehandle 22 is moved by the user between the two positions, the camming action of the curved surfaces of the rib and groove causes thetab 122 to deflect downward, releasing the rib from the groove in which it was engaged. - The actuator/
nozzle member 49 also includes a lower surface that is configured to engage the stem of the canister. Referring toFIGS. 2A and18 , the lower surface includes a tapered frustro-conical portion 62 that engages the rim ofstem 133. This tapered surface provides a good seal with the stem, preventing undesirable leaking of the aerosol composition into the interior of the housing. As shown inFIG 18A , in some embodiments the frustro-conical portion 62 may include a thin layer of anelastomeric material 64, providing a resilient gasket between the rim of the stem and the lower surface ofmember 49. - A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the scope of the invention.
- The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as "40 mm" is intended to mean "about 40 mm".
- While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
