With reference to figure 3 and 4, can see that the inside of housing 100 comprises four arc protrusions 114 that separate.Each protrusion 114 is for that protrude and radially inwardly outstanding.When locking bushing 76 rotated to respect in four possible aligned positions of closure 26 and housing 100 any one, each protrusion 114 was adapted to be received in the recess 98 in the flange 97 of locking bushing 76.The arc protrusion 114 of housing and the arc recess 98 of locking bushing flange play a role together with the feature portion that engages one another of the position that the selection that limits the relative rotary alignment between locking bushing 76 and the housing 100 is provided.Protrusion 114 and recess 98 also allow or allow that locking bushing 76 (with respect to closure 26 and housing 100) rotates between at least one positions that locks releasedly of another position of rotation of the drivable position of at least one release of the position of rotation of (1) corresponding sleeve 76 and (2) corresponding sleeve, as will be explained in more detail below.Each sleeve recess 98 plays a role to keep housing protrusion 114 releasedly with releasable engaged pawl, locking bushing 76 is selectively remained on releasedly correspondence with respect to one in two or more position of rotation of the locking and unlocking state of the operation of monoplunger pump assembly.

The inside of housing 100 has at least one and four radially inwardly outstanding vertical fins 111 of in-to-in preferably, and each is adapted to be received in fin 111 between the fin 68 of any two vicinities on the outside of closure 26.This prevents the relative rotation between housing 100 and the closure 26.

Housing fin 111 is also playing a role during equipment is installed to whole monoplunger pump assembly on the container 22 by adding a cover automatically, to prevent the relative rotation of housing 100 with respect to closure 26, and this allow to install automatically equipment is caught and rotary shell 100 to cause rotating whole monoplunger pump assembly, make closure screw thread 32 suitably be threaded on the container neck screw thread 58 (Fig. 6).

In preferred form of the present invention, preferably by bar or binary pair 120 (Fig. 1 and 2) function driver 42, the user can pull bar or binary pair 120 lean against on the top of actuator or button 42, with downward promotion button (relatively Figure 12 and Figure 14).For this reason, the monoplunger pump assembly comprises from housing 100 to the outstanding binary pair strut member 126 (Fig. 1 and 2) in the actuator mouth of pipe 45 back.Binary pair strut member 126 comprises a pair of outwards outstanding minor axis 128 (Fig. 3) that separates.Each minor axis has design that the inclined-plane is provided and to allow binary pair 120 is installed to bevelled upper surface 130 (Fig. 4) on the binary pair strut member 126.

As shown in Figure 2, binary pair 120 has the rear end part that limits a pair of boring that separates 132 (among Fig. 2 only one of them as seen).Each boring 132 is fit to receive in the binary pair strut member minor axis 128, installs so that the pivot of binary pair 120 on binary pair strut member 126 to be provided.As Fig. 2 and 8 as seen, the upper end of binary pair strut member 126 limits towards outer horizontal crosspiece or stops surface 138.As shown in Figure 8, crosspiece or stop below the wall 140 of back that surface 138 is positioned at binary pair 120 and the wall 140 of contiguous back rotate above position shown in Figure 8 in the counterclockwise direction to prevent binary pair 120.

The fwd part qualifying part ground of binary pair 120 passes through elongate opening, hole or the slit 146 that flowing materials are distributed in slit 146 around the actuator mouth of pipe 45 location to allow from the mouth of pipe 45.

Shown in Fig. 2 and 8, the fore-end of binary pair 120 limits the bar part 150 that available finger is caught, and user's finger can refer to catch bar part 150 to pull down or crowded binary pair 120 leans against on the top of actuator or button 42.

The downside of binary pair 120 comprises that the power of the top end that is used to be bonded on actuator or button 42 bears the structure that drives district 43.For this reason, and with reference to figure 6 and 8, binary pair 120 comprises the cam fin 154 of two linearities that separate, and each is aligned to cam fin 154 and is in substantially parallel relationship to the actuator mouth of pipe 45 and each and is adapted to be received in in the groove 54 in the top of actuator 42 one.

Fig. 1 and 5-8 show and are in the still monoplunger pump assembly of lock-out state that does not drive.As shown in Figure 5, the user can see that the side of pump is to observe locking bushing 76, locking bushing 76 preferably provides suitable mark, " open " such as the speech above double-headed arrow, clearly visible and the prompting user of this mark is at cw or anticlockwise direction spin locking sleeve 76, so that system is placed on " opening " state of bar 150 driving pumps of permission by pulling down binary pair 120.

When the monoplunger pump assembly locks as shown in Figure 5, a top joining edge (for example, edge 81 shown in Figure 5) directly is positioned at below the mouth of pipe 45 that laterally extends, because actuator 42 is biased to the dead position that does not drive on top by pump barrel 24 (Fig. 8), the mouth of pipe 45 is in its maximum height (its maximum height is determined with engaging of binary pair cam fin 154 by the top of actuator 42, by the wall 140 of binary pair back and any further upward movement that prevents binary pair cam fin 154 that engages of binary pair strut member constraint crosspiece 138 (Fig. 8)).

If the user attempts to pull down binary pair 120, the following side engagement top joining edge (edge 81 among Fig. 5) of the actuator mouth of pipe 45 moves downward to prevent binary pair 120, thereby and prevents to drive the monoplunger pump assembly.

By engaging of the recessed recess 98 (Fig. 2) of locking bushing flange and enclosure interior protrusion 114 (Fig. 2-4), locking bushing 76 is remained on the locking orientation releasedly.When the user wishes operating pumps with the distribution flowing material, the user simply need be at cw or anticlockwise direction spin locking sleeve 76 so that one among two locking bushing recess 91 and 92 (Fig. 2) is taken to below the actuator mouth of pipe 45, to set up released state (Fig. 9-12).Fig. 9,10 and 12 shows the recess 91 in the actuator mouth of pipe 45 aligned beneath location.When the user begins locking bushing 76 when latched position (Fig. 1 and 5) rotates to unlocked position (Fig. 9 and 10), when the user applies enough power with when housing protrusion 114 (Fig. 2) goes out of lock sleeve recess 98 (Fig. 2), the user will notice the sensation of the initial sense of touch of resistance.When locking bushing 76 has been rotated by 90 degrees so that locking bushing recess 98 is when engaging housing protrusion 114 once more, when recess 98 receives protrusions 114, the user will feel that resistance reduces.

In the preferred embodiment of monoplunger pump assembly, the user will hear that indication has arrived the buckle of hearing or the click of release (or locking) position.Can by by the material manufacture monoplunger pump component parts that is fit to of the temporary transient elastomeric distortion that necessary part is provided (in locking bushing 76 and the housing 100 at least one or all) realize the sensation of sense of touch of the resistance that increases or reduce and click clatter or the buckle that can hear.Such material is preferably those materials that belongs to alkene family (for example, polypropylene, polyethylene etc.) or belong to engineering level plastics family (that is, nylon, acetyl etc.).

The preferred embodiment of locking bushing 76 preferably includes the mark that is positioned at each top joining

edge

81 and 82 belows, such as the speech above double-headed arrow " locking ", be the state that can not drive that the user can be placed on assembly by cw or left-hand revolution locking bushing 76 locking subsequently with the indication user.

In the preferred embodiment that illustrates of monoplunger pump assembly of the present invention, locking bushing 76 has four position of rotation-be used to lock, first position of rotation of pump, second position of rotation (surpassing first position of rotation, 90 degree) that is used for the release pump at the hand of rotation of selecting, be used for locking once more the 3rd position of rotation (surpassing second position of rotation, 90 degree) of pump and be used for once more the 4th position of rotation (surpassing the 3rd position of rotation 90 degree) of release pump at the hand of rotation of selecting at the hand of rotation of selecting.

(not shown) in the embodiment that substitutes, locking bushing only can provide second position of rotation of two position of rotation-be used to lock first position of rotation of pump assembly and be used for release pump assembly.In such embodiment that substitutes, locking bushing only need provide the top joining edge that a downside that is used to engage the mouth of pipe 45 moves downward to prevent actuator 42, and only need provide one and be used to the recess of allowing that the actuator mouth of pipe 45 moves downward.

(not shown) in the embodiment that another substitutes, if locking bushing 76 is revised as recess and the top joining edge that provides additional, locking bushing 76 can provide more than four position of rotation.

In the preferred embodiment that illustrates, locking bushing 76 provides recess (recess 91 and 92) and top joining edge (edge 81 and 82) with the 90 degree increments that equate in the periphery of the top of locking bushing.Yet, (not shown) in the embodiment that substitutes, top joining

edge

81 and 82 and the interval of the increase of

recess

91 and 92 do not need to equate, if yet package does not comprise the clearly mark or the mark of the different position that identification can be selected, unequal interval and unequal increment of rotation be " user friendly " inadequately.

Figure 15-17 show may be favourable in some applications to modification of the present invention.Specifically, the easier little difference of allowing the size of locking bushing 76 and/or housing 100 of design that this substitutes is because the size of each unit may change.As previously described, in first embodiment of monoplunger pump assembly, locking bushing flange recess 98 receives housing protrusion 114 (Fig. 2) at the relatively rotation place of selecting.When the user begins that locking bushing 76 rotated to next position of rotation, move out of sleeve recess 98 and bearing against on the bigger surface of the diameter of locking bushing bottom peripheral edge flange 97 of housing protrusion 114.Compare with in housing protrusion 114 is received in locking bushing recess 98 time, this has increased the engaging force between housing 100 and the locking bushing 76.For such design, wish between the cylindrical surface of the flange 97 between housing protrusion 114 and the recess 98, to provide the predetermined engaging force of constant usually.Provide suitable design relation to realize between this circle diameter that can limit by innermost point of contact usually on the surface of the diameter of the outside face of locking bushing flange 97 and the protrusion by housing protrusion 114.That is, wish that housing protrusion 114 should have the radially innermost point of contact of the circle of the diameter that limits the outside face that is slightly less than locking bushing flange 97.

Yet,, locking bushing 76 and housing 100 be fabricated to have enough little dimension limit can be difficult if no matter use which kind of material moulding part all to use identical mfg. moulding die size.For example, maker can wish to make the monoplunger pump assembly of two or more types, wherein, one type locking bushing 76 and/or housing 100 are molded by one type thermoplastic material, and wherein, the locking bushing 76 of another kind of type and/or housing 100 are molded by second kind of different thermoplastic material.

Different thermoplastic materials can have different molded after contraction characteristics.Find that also different molded after contraction characteristics may be only by using different colorants to cause in identical thermoplastic moulding material.Some colorants cause than the more molded after contraction of other colorant.Thereby, after molded parts have cooled off, may be by the final size of the molded parts of a kind of material with different by the final size of the molded parts of different materials.By the contraction phase of the contraction of molded locking bushing 76 of first material and/or housing 100 and locking bushing 76 when molded and/or housing 100 by second material than the engaging force different (littler or bigger) between the greater or lesser columniform surface (between recess 98) that can cause housing protrusion 114 and locking bushing flange 97.

Thereby, if no matter use the moulding material of which kind of type all to use the molded special parts of identical mould, result's molded back size may be according to changes in material, and this will cause when locking bushing rotates between " locking " and " release " position the engaging force between the locking bushing 76 and housing protrusion 114 greater or lesser.Thereby, may find that by the user of the molded parts of a kind of material power that spin locking sleeve 76 needs is greater than or less than the power that parts are wherein needed by the locking bushing 76 in the molded assembly of different materials of rotating.In fact, though the user rotation torque that the locking bushing 76 when molded needs by a kind of material may be well in the torque range of hope, but the rotation torque that the locking bushing when molded 76 needs by second kind of different material may exceed the torque range (, rotate too tight or too loose) of hope.

Maker wishes to use only a kind of mould to come moulded locking sleeve 76 and only a kind of other mould to come molded shell 100 usually.Maker does not wish according to the thermoplastic type of material of using or according to the mould of the colorant that adds thermoplastic material to as the many different sizes of locking bushing 76 uses.Similarly, maker wishes usually no matter use the thermoplastic material of which kind of type or the colorant that adds thermoplastic material to of which kind of type all to use only a kind of mould to come molded shell 100.

The embodiment that substitutes shown in Figure 15-17 allows maker by only using a mould by different thermoplastic material (having different shrinkage characters) moulded locking sleeve 76, and with mould only by different thermoplastic material (having different shrinkage characters) molded shell 100.The embodiment that substitutes provides particular structure, is used to allow the shrinkage character of variation, and also providing simultaneously wherein can be at the assembly of the bigger and littler diameter that does not influence the bonding part of allowing parts under the situation of user to the operation of locking bushing nocuously.

In the embodiment that substitutes shown in Figure 15-17, locking bushing 76A has the design with the top modification of comparing with reference to the locking bushing 76 of the description of first embodiment shown in the figure 1-14.The locking bushing 76A that revises plans to use with top housing 100 and other parts of describing with reference to first embodiment shown in the figure 1-14.The locking bushing 76A that revises is similar to the locking bushing 76 of first embodiment.The locking bushing 76A that revises comprises the first upper joint edges 81A, the second upper joint edges 82A, the first recess 91A and the second recess 92A.These features play a role in the mode identical with the characteristic of correspondence of the locking bushing 76 of above-described first embodiment.

The locking bushing 76A that revises comprises the perimeter flange 97A that extends radially outwardly of contiguous locking bushing bottom.Different with the locking bushing 76 of first embodiment, the locking bushing 76A of modification itself does not form the recess of the recess in the flange 97A.But locking bushing 97A comprises four pairs of slopes that separate, and Figure 15 shows wherein a pair of slope, comprises the first slope 181A and the second slope 182A.Each slope has the surface of long bevelled slight curvature.The first slope 181A comprises that also shorter steeper bevelled keeps wall 186A, and the second slope 182A comprises that also shorter steeper bevelled keeps wall 188A.Keep wall 186A to separate from keeping wall 188A.

Spatial design between wall 186A and the 188A when rotating in two predetermined latched positions or two the predetermined unlocked positions as locking bushing 76A, the protrusion 114 (Fig. 4) of the protrusion of inwardly giving prominence on the inboard of housing case 100.The outer peripheral edge cylindrical surface of flange 97A between two maintenance wall 186A and the 188A is designed to have the inwardly outstanding enough little diameter with housing case protrusion 114.Innermost point on the protrusion 114 that protrudes can engage the outside face that keeps the flange 97A between wall 186A and the 188A a little, but does not need to contact practically the outside face of flange 97A.

Can allow significant dimension limit.Promptly, locking bushing 76A can be molded by multiple material with different shrinkage percentages, wherein, the outer peripheral edge diameter of the cylindrical surface of flange 97A can change according to the material (comprising according to the colorant materials that will be added to moulding material) that is used for moulded locking sleeve 76A a little.Each keeps the radially outward outstanding significant amount of

wall

186A and 188A, and the radially inwardly outstanding significant amount of each housing protrusion 114.When parts are in one or two " release " position in two " locking " positions one, between inwardly outstanding protrusion 114 and maintenance wall 186A that outwards gives prominence to and 188A, there are enough interference, so that be provided at the significant resistance of a direction or the rotation of another direction.The user must be applied to enough torques locking bushing 76A (at a direction or another), and one of them keeps wall (is 186A or 188A according to hand of rotation) housing protrusion 114 through engaging so that move.

When the user applies enough torques, locking bushing 76A and/or housing 100 will experience temporary transient elastic deformation, make locking bushing keep wall (186A or 188A) can move through housing protrusion 114.As spin locking sleeve 76A during further away from initial locking or unlocked position, the bevelled side of the length of slope (181A or 182A) will engage the innermost point of contiguous housing protrusion 114 subsequently.

When locking bushing 76A further rotates, contiguous housing protrusion 114 motions of the exterior cylindrical surface of the flange 97A of the end of the merging of two convergents on the slope of contiguous length.According to the diameter of flange 97A (the final contraction of the thermoplastic moulding material by being used for moulded locking sleeve 76A is determined), contiguous housing protrusion 114 can engage or the exterior cylindrical surface of faying flange 97A not.No matter whether exist any joint resistance, user will clearly notice drag torque from when spin locking sleeve 76A initially with move maintenance wall (186A or 188A) steep and long bevelled slope during through housing protrusion 114 drag torque of experience reduce significantly.When the user when identical hand of rotation further continues spin locking sleeve 76A, next long slope begins to engage or more effectively engage housing protrusion 114.The joint resistance increases, in housing protrusion 114 is snapped into down space between a pair of slope maintenance wall once more.The sensation indication user of this sense of touch has arrived next predetermined position of rotation (locking or release).In most preferred embodiment, parts are snapped into and send the click that can hear in the predetermined position, further to represent to have arrived next predetermined position.

Thereby the locking bushing 76A of above-mentioned modification can allow the diameter difference of locking bushing flange 97A and/or housing 100.The amount of the dimension limit that can allow keeps the radially outward outstanding distance of wall (186A and 188A) to determine by housing protrusion 114 inwardly outstanding distance and slope to a great extent.

Above-mentioned locking system can be fit to use together with the package with aerosol dispenser tube (that is aerosol distributing valve) rather than pump dispenser (pump dispenser of describing with reference to figure 1-17 for example, 24).Figure 18 shows the package 200 that uses embodiment that can manual allocation component of the present invention, wherein, the form of assembly is to comprise that form is the aerosol allocation component that is installed in the aerosol dispenser tube of the aerosol distributing valve 224 (Figure 19 and 21) on the container 222 (Figure 18 and 21).Figure 19 shows the interior representative type aerosol distributing valve 224 of mouth that can be used as the part of the assembly on the container 222 and be fit to be installed in container 222.

Container 222 typically is has the metal can that is rolled into the upper limb that crimping 223 (Figure 21) is installed.Container 222 is adapted at aerosol distributing valve 224 belows and keeps product (for example liquid (not shown)).Aerosol distributing valve 224 has main body 225 (Figure 19 and 21).The part of aerosol distributing valve main body 225 typically extends into vessel port.

Aerosol distributing valve 224 (that is aerosol dispenser tube) can be any suitable traditional or special type.For the traditional aerosol distributing valve 224 of representative type, the bottom of aerosol distributing valve main body 225 is attached to traditional dip-tube 234 (Figure 19 and 21), and the over top (Figure 21) of the outstanding container 222 in the upper end of aerosol distributing valve 224.

Aerosol distributing valve 224 is installed to container 222 by the device that is fit to.Such device that is fit to is traditional valve mounting cup 226 (Figure 19 and 21), valve mounting cup 226 has mounting flange 227, mounting flange 227 has outer peripheral edge part 227 ' (Figure 19), outer peripheral edge part 227 ' can around vessel port crimping 223 and as shown in figure 21 on the pad that covers 238 curl, arrive the firm attachment at the top of container 222 so that mounting cup 226 to be provided.

Mounting cup 226 comprises the inwall 228 (Figure 21) of the annular of the outstanding opening that passes through of a part that limits aerosol distributing valve 224.The inwall 228 of the annular of mounting cup comprises the flanging 229 (Figure 21) of the exterior part of castellated portion on the outside of the main body 225 that is used to engage aerosol distributing valve 224 or fin 230.

More generally, the feature of valve mounting cup 226 can be fixed on accessory or closure in the container 222 with aerosol distributing valve 224 for being used for, and term more generally " closure " uses in some accompanying Claim, wherein, be appreciated that, term " closure " has enough extensively (for example especially to comprise aerosol distributing valve mounting cup, cup 226) or distribute the pump barrel closure connotation of (for example, will distribute pump barrel to be installed to the closure 26 of container with reference to figure 2 and 6 being used for of describing above).

The main body 225 of aerosol distributing valve or dispenser cartridge 224 limits internal chamber (invisible).In representative type aerosol distributing valve 224, the tube or the main body 225 of valve 224 be hollow and have a bottom of the content of the pressurization in the container 222 being opened (by the dip-tube 234 of attachment).Container 222 typically keeps the liquid product by the propelling gas pressurization.

Handle 240 is outstanding from the top of aerosol distributing valve main body 225.Compression spring (invisible) in the aerosol distributing valve main body 225 is to upper offset handle 240, to give prominence to the opening that limits in the inboard of the pad 239 (Figure 19 and 21) of the annular at the place, top of the main body 225 of aerosol valves 240.The vertical discharge orifice 241 (Figure 19) of in-to-in of the exterior actuator button 242 (Figure 19 and 21) on the upper end that is installed in handle 240 is opened and be connected to the upper end that the part on the top of handle 240 is included in handle 240.Below the upper end of handle 240, handle 240 has the aperture (invisible) of one or more side direction that the vertical discharge orifice 241 in the part with the top of handle 240 is communicated with.Before depressing actuator button 242, the inner surface of vicinity at the pad 239 (Figure 19 and 21) of the annular at the place, top of the main body 225 of aerosol distributing valve 224 orientated in the aperture (invisible) of the side direction in the handle 240 as.When depressing actuator button 242, pushing handle 240 leans against on the spring (inboard invisible in aerosol valves main body 225) downwards, so that the aperture (invisible) of side direction is repositioned in the main body of pad 239 (Figure 19 and 25) below, and this allows the fluid of pressurization upwards to flow along dip-tube 234 in container 222, main body 225 by aerosol valves 224, enter boring 241 in the handle 240 by the aperture, and from actuator button 242 outputs.

After driving the spraying allocated product of aerosol distributing valve 224 with atomizing, the user stops driving operation, makes the quiescence (Fig. 1 and 2 1) that aerosol distributing valve parts is turned back to the rising that valve 224 wherein cuts out by contained spring (invisible).

Should be appreciated that the special design of aerosol dispenser tube (that is aerosol distributing valve) 224 can be applicable to from container 222 (being with or without induction pipe 234) allocated product and the design by handle 240 output for any.The detailed design and the structure itself of dispenser cartridge or aerosol distributing valve 224 do not form a part of the present invention, except aerosol distributing valve 224 is fit to install and remain on the container 222 suitably and valve 224 (for example comprises outwards outstanding handle with the installation system that is fit to, handle 240), when driving valve 224, from outwards outstanding handle discharging product.

Actuator or button 242 limit discharge-channel 244 (Figure 21), discharge products by discharge-channel 244 from handle 240.Discharge-channel 244 extends from the inner sleeve 246 that limits entrance cavity, and the upper terminal of handle 240 or far-end can be press fit in the entrance cavity.The exterior part of discharge-channel 244 is limited in the outstanding nozzle of side direction or the mouth of pipe 245 (Figure 18,19 and 21).The exterior end sections of discharge-channel 244 has the structure of annular, and traditional mechanical separative element or spraying embolus 250 (Figure 19 and 21) with outlet aperture 252 (Figure 19 and 21) can be press fit in the structure of annular.

Actuator 242 has constraining force and bears the top that drives district 243 (Figure 19), and power is born and driven the parallel groove 54 that district 243 comprises two linearities that separate of adjacent assemblies orientation notch 256 location.With top the same with reference to the groove 54 in the pump dispenser actuator 42 of figure 1-14 description, these two grooves 254 are fit to receive the part of trigger structure, the user operates this trigger structure with downwards motion actuator 242 and handle 240 in aerosol distributing valve 224, with from valve 224 distributing fluids.The fluid of pressurization is exported from the nozzle orifice 252 in the nozzle or the mouth of pipe 245 with the mist spraying in container 222.In aerosol distributing valve 224 inboards, spring (invisible) effect leans against on the bottom of handle 240 of aerosol distributing valve 224 inboards with biasing handle 240, and when the propulsive effort (operating effort) of release action in driver drives district 243, upwards actuator 242 is positioned at the dead position (Figure 18 and 21) of rising.Thereby after the spraying dispense liquid product with atomizing, the user stops driving operation at driving aerosol distributing valve or tube 224, the feasible quiescence (Figure 18 and 21) of parts being returned rising by contained spring.

Lock or locking bushing 276 distribute valve handle 240 and actuator 242 rotatably to install around aerosol.Locking bushing 276 is roughly the same with the locking bushing 76 of top first embodiment with reference to figure 1-14 description.Locking bushing 276 limits first upper joint edges 281 and second upper joint edges 282.Locking bushing also limits first recess 291 and second recess 292 (Figure 19).In the preferred embodiment that illustrates, two top joining edges 281 and opened in 282 minutes 180 the degree, and two recess 291 and opened in 292 minutes 180 the degree.(not shown) in the embodiment that substitutes, locking bushing 276 only can have a top joining edge and recess only.(not shown) in the embodiment that another substitutes, locking bushing 276 can have three or more tops joining edge and three or more recess.

In the preferred embodiment that illustrates, locking bushing 276 has the bottom by crimping 294 (Figure 21) qualification of rounding.As Figure 19 and 21 as seen, locking bushing 276 comprises the perimeter flange that extends radially outwardly 297 of contiguous locking bushing bottom.Flange 297 limits four the arc recesses 298 (Figure 19) that separate circumferentially with 90 degree increments.

Aerosol distributing valve assembly comprises fixing outer sleeve or housing 300 (Figure 19,20 and 21).As shown in figure 21, stationary sleeve or housing 300 are fit to around the part layout of the bottom of locking bushing 276.Housing 300 has the bottom of opening.Housing 300 limits inside ringed groove 306 (Figure 20), and groove 306 contiguous housing bottoms and radial face are inwardly with the outer peripheral edge part 227 ' with snap fit engagement receiving valve mounting cup flange 227, housing 300 is remained on the cup 226, as shown in figure 21.

As shown in Figure 21, housing 300 has the upper end of opening that receives locking bushing bottom and locking bushing perimeter flange 297.As Figure 19 and 21 as seen, the upper end of housing 300 has a plurality of radially inwardly outstanding tops maintenance lips 310 that separate.Housing 300 also has a plurality of inwardly outstanding bottoms that are positioned at the height that is lower than top maintenance lip 310 and keeps lips 312 (Figure 19 and 21).The bottom keeps lip 312 to limit the shelf of segmentations, and the spatial vertical between the section of shelf or lip 312 and the top maintenance lip 310 aim at.As shown in Figure 21,

Should be appreciated that, in above-mentioned two aerosol valves assembly embodiment (embodiment of the modification shown in the embodiment shown in Figure 18-25 and Figure 26-28), can further revise locking bushing (

sleeve

276 or 276B), replace arc recess (recess 298 or 298B) with the slope 181A that describes with top embodiment with reference to the pump assembly locking bushing 76A shown in the figure 15-17 and the structure of 182A.

The present most preferred embodiment of locking system is shown in Figure 29-37, and it can be fit to and have the aerosol dispenser tube (promptly, such as the top aerosol distributing valve of describing with reference to figure 18-28) or the package of the pump dispenser tube pump dispenser 24 of figure 1-17 description (for example, with reference to) use together.Figure 29-37 shows the package 20C that uses embodiment that can manual allocation component of the present invention, and wherein, the form of assembly is the pump dispenser 24C (Figure 29 and 30) that is installed on the container 22C.

Except container 22C, the parts of package 22C comprise pump barrel 24C, closure 26C, actuator or button 42C, locking bushing 76C, housing 100C and binary pair 120C.Container 22C, pump barrel 24C, closure 26C, actuator 42C, locking bushing 76C and housing 100C container 22, pump barrel 24, closure 26, actuator 42, the locking bushing 76 with first embodiment shown in Fig. 1-14 respectively are identical with housing 100.Locking bushing 76C can be identical with the embodiment 76A that substitutes shown in the embodiment 76 shown in Fig. 1-14 or Figure 15-17.The detailed feature of container 22C, pump barrel 24C, closure 26C, actuator 42C, locking bushing 76C and housing 100C and operation are respectively with the feature of the top first embodiment container 22, pump barrel 24, closure 26, actuator 42, locking bushing 76 (or 76A) and housing 100 with reference to figure 1-17 description with operate identical.

As shown in Figure 29, locking bushing 76C has the first top joining edge 81C and the second top joining edge 82C.The first recess 91C (Figure 29) is positioned between two joining edge 81C and the 82C.The second recess 92C (Figure 32) orientates as and becomes 180 degree with the first recess 91C and be positioned at equally between two joining edge 81C and the g2C.Actuator 42C has the mouth of pipe or nozzle 45C.

In the 5th embodiment shown in Figure 29-37, binary pair 120C is to shown in Figure 2 and similar but inequality with reference to the binary pair 120 of the description of the embodiment shown in the figure 1-14 in the above.

Comprise that at binary pair 120C form is that the binary pair 120C of the 5th embodiment is different with the binary pair 120 of first embodiment on the binary pair lock stopper this point of the arm 500C (Figure 36) of extension downwards.The arm 500C of binary pair 120C comprises two sidewall 502C that separate by cross wall 504C (Figure 32 and 37) associating.As shown in Figure 36, arm 500C limits the recess 508C at right angle substantially.As shown in Figure 30, recess 508C is fit to be depicted as in the top joining edge of (Figure 29 and 30) reception locking bushing 76C when being in the locking orientation any as locking bushing 76C.In Figure 29, locking bushing 76C is in first position of rotation, first position of rotation limits the first locking orientation, and wherein, the first joining edge 81C is directly below binary pair lock stopper or engaging arms 500C and can lock stopper with binary pair or engaging arms 500C engages.If locking bushing 76C Rotate 180 degree (to the second locking orientation), the second top joining edge 82C of locking bushing 76C engages trigger arm 500C, moves downward to prevent binary pair 120C.

The first locking orientation at locking bushing 76C shown in Figure 29, the second top joining edge 82C separates below the actuator mouth of pipe or nozzle 45 a little, attempt depression of trigger 120C even make, can power be applied to nozzle 45C (because trigger arm 500C prevents that with the engaging of the first top joining edge 81C of locking bushing binary pair 120C from moving downward, make and can not depress actuator 42C) by edge 82C yet.The second locking orientation below the first top joining edge 81C is positioned at nozzle 45C, similarly, because joining edge 81C separates below nozzle 45C equally, power can not be applied to nozzle 45C, and because trigger arm 500C engages the second top joining edge 82C, nozzle 45C can not reduce.

Turn 90 degrees (cw or conter clockwise) if locking bushing 76C only revolves, first or second recess 91C of locking bushing or 92C are positioned at trigger arm 500C below respectively.Figure 32 shows locking bushing 76C rotation so that the first recess 91C is positioned at trigger arm 500C below.Subsequently can depression of trigger 120C, shown in Figure 33 and 34, with downward promotion actuator 42C to drive allocation component.As shown in figure 34, recess 91C and the 92C of locking bushing 76C are enough dark, the edge of the locking bushing that the bottom that makes actuator nozzle 45C not collide arbitrary recess is located.

Because the unique design of the binary pair 120C among the 5th embodiment of allocation component, if damage the possibility of actuator 42C and its nozzle 45C when reducing package 20C greatly and unexpectedly falling.This be because, when locking bushing 76C be in locking orientation (Figure 29 and 30) or be in release but the orientation (Figure 31 and 32) that does not drive or when being in orientation (Figure 34 and 33) release and that drive, actuator nozzle 45C does not engage the edge of locking bushing 76C.Thereby if package 20C not inadvertently falls with being inverted and binary pair 120C lands, binary pair 120C can not cause actuator motion nozzle 45C to lean against on the locking bushing 76C.At lock-out state or released state, package 20C not inadvertently falls with being inverted and can not cause by locking bushing 76C or by binary pair 120C shock load being applied to nozzle 45C on binary pair 120C.This has minimized the possibility that between such impact epoch nozzle 45C is departed from.

The 5th embodiment shown in Figure 29-37 is provided at the design of first embodiment shown in Fig. 1-14 or the pro forma further advantages that substitute shown in Figure 15-17.Especially, in the embodiment shown in Fig. 1-17, when locking bushing 76 is in the locking orientation (Fig. 8), if attempt to press very at full tilt binary pair 120, binary pair cam fin 154 may cause actuator 42 perk at a certain angle or bolt jail.Especially, as shown in Figure 8, if power is applied to binary pair 120, cam fin 154 will at first tend to push away downwards on the part of the back of actuator 42.Promote downwards actuator 42, up to the top joining edge of the following side engagement locking bushing 76 of nozzle 45.Yet, if the user continues big power is applied to binary pair 120, when actuator 42 pivoted a little around the junction between the top joining edge of the joint of the downside of actuator nozzle 45 and locking bushing 76, the power on the part of back at top of actuator 42 of being applied to by cam fin 154 can cause actuator 42 to twist a little downwards or be angled on the handle 40.

On the contrary, for the design of using among the 5th embodiment shown in Figure 29-37, when locking bushing is in the lock state, because the top joining edge of vicinity that trigger arm 500C engages locking bushing 76C is with the further motion that prevents binary pair 120C and prevent that actuator nozzle 45C from engaging locking bushing 76C, depression of trigger 120C can may not cause actuator 42C downward power angled around locking bushing 76C or that pivot to be applied to actuator 42C.

As what use among the 5th embodiment that describes with reference to figure 29-37 in the above, binary pair 120C can also use with the aerosol distributing valve 224 of (or in its embodiment that substitutes shown in Figure 26-28) and the aerosol dispenser tube of actuator 242 shown in Figure 18-25.Binary pair 320 among the aerosol embodiment shown in Figure 18-25 is enough with each energy of binary pair among the aerosol embodiment shown in Figure 26-28 and top alternative with reference to the similar new binary pair of the binary pair 120C of figure 29-37 description, but need the angle in the orientation of adjusting binary pair stopper hammerlock 500C, make suitably to engage the upper limb of aerosol dispenser locking bushing at the lock-out state arm.In aerosol dispenser, use such binary pair will provide with on regard to the advantage of the identical type of the pump dispenser tube allocation component description shown in Figure 29-37.

Though about with the aerosol dispenser tube of the pump dispenser tube of trigger actuation or trigger actuation (promptly, the aerosol distributing valve) presently preferred embodiment of using has together illustrated and has described the feature of hope more of the present invention, should be appreciated that, can in the allocation component of other type, be included in some features of using aspects more of the present invention or embodiment in those allocation component that do not have binary pair.

In addition, in the preferred form of allocation component of the present invention, the different parts of assembly can be easily integrally or at least in part by the thermoplastic material manufacture of injection molding.

In the past apparent in the face of detailed description of the present invention and its explanation, can under the situation of the real spirit and scope that do not depart from new design of the present invention or principle, carry out many variations and modification.
