Description
LIQUID DISPENSER ASSEMBLY WITH ADAPTOR
Background and Summary of Invention This invention relates to a liquid dispenser assembly, and particularly such an assembly for use with a liquid container and where the dispenser is operated remotely from the container- A tube connects the dispen-5 ser with the container for feeding the liquid to thedispenser. The present invention is an imp~ove---ent over remotely operated dispensers of the type described above, and further includes a unique adaptor secured to the container and to which the dispenser may be connected for 10 sale and storage and disconnected for remote operation.
Liquid dispenser assemblies of the type to which this invention is generally directed are well-known in the art. The dispenser assembly shown in Figure 1 of the drawing is typical of the prior art. The dispenser as-15 sembly 10 of the prior art includes a trigger sprayer 12 CA 022~883~ 1999-01-20 having a neck portion 13, a handle portion 14 and a tube 16. The trigger di~penser 12 is of the type well-known in the art and which is operable by means of a trigger 18 to pump liquid from a suitable container, such as con-5 tainer 20, and out a nozzle and orifice cap 22 of thedispenser. The cap 22 may be fixed or may be ad~ustable to provide a variety of spray patterns, all of which is well-known. The dispenser assembly 10 also includes a threaded closure 24 to connect the handle portion to the 10 neck portion of the dispenser.
The contAinpr 20 is of a type typically found in retail stores and may be of plastic and have a threaded neck 30 and handle portion 32 for carrying and holding the cont~i n~r . When the cont~iner and dispenser assembly 15 are packaged for retail sale in the stores, the container has a threaded cap 34 with a hole 36 in the top. A gas-ket 38 is located between the cap and the threaded neck 30 of the bottle to seal the opening and pre~ent the liquid within the bottle from spilling. When packaged 20 for sale in the store, typically the dispenser assembly, including the trigger sprayer 12, portion 14, and tube 16, are packaged in a sealed plastic bag. The bag has a hole so that the bag containing the dispenser assembly may be hung over the neck 30 of the contAiner with the 25 cap 34 extending through the hole. To use the prior art assembly of Figure 1, the user removes the plastic bag from the container, and removes the dispenser assembly from the plastic bag. The user then inserts the end of the tube 16 through the hole 36 and pierces the gasket 30 38, thus inserting the tube into the liquid within the container. The user holds the container with one hand while operating the trigger sprayer with the other to pump the liquid from the container and out the dispenser.
The container and dispenser assembly of Figure 1 typical-35 ly are used to dispense products such as insecticides,herbicides, and the like.
.. . . .. . . .
CA 022~883~ 1999-01-20 There are several disadvantages associated with the contA i ner and dispenser assembly of Figure 1. Once the gasket is pierced, if the cont~;ner is tipped over during use, the liquid within the contA i ner will leak 5 between the tube and gasket and between the tube and opening 36. Another disadvantage is that the dispenser assembly is awkward to store and there is no provision for sealing the contA i ~r . Still another disadvantage is that the plastic bags contAining the dispenser assemblies 10 frequently become separated from the contAiners in the retail store creating customer confusion and annoyance.
The present invention overcomes these problems.
In accordance with the present invention, there is provided an adaptor that is secured to the neck portion 15 of the contAi~er. While the adaptor may be disconnected from the cont~iner~ it remains connected to it when sold in the stores, when in use, and when the dispenser is stored during non-use. The dispenser and adaptor have means for connecting the dispenser and adaptor together 20 with the tube exten~ing from the dispenser, through the adaptor, and into the container. The dispenser may be disconnected from the adaptor while the adaptor remains secured to the contA i ner ~ for operation of the dispenser remotely from the contAiner. The tube extends through 25 the adaptor in sealing engagement therewith to prevent liquid from entering the interior of the adaptor. Thus, the interior of the adaptor remains dry and sealed from the liquid. When the dispenser assembly is connected to the adaptor, the handle portion of the dispenser extends 30 into the interior of the adaptor and remains dry and out of contact with the liquid. In use where the dispenser is disconnected from the adaptor and operated remotely, the adaptor re~i n~ secured to the container to provide a seal against spilling.
In one preferred embodiment of the invention, the adaptor has a chamber therein. The tube has a preformed CA 022~883~ 1999-01-20 coil portion housed within the chamber with the dispen~er and adaptor connected. The coil portion extends upon disconnecting the dispenser from the adaptor for remote operation of the dispenser. This embodiment has the 5 advantage that the exterior surface of the preformed coiled tube portion which may come in contact with the user during use, is protected from the liquid, it being housed within the adaptor chamber.
These and other advantages of the invention are 10 apparent from the drawing and detailed description to follow.

10 Detailed Description of pref~rred Embo~iments With reference to the drawing, one preferred embodiment of the liquid dispenser assembly with adaptor of the present invention is shown in Figures 2-4. Gener-ally, the dispenser assembly is the same as shown in 15 Figure 1 except that the closure 24 has an outwardly extending shoulder 40 and an internally threaded ring portion 42 depending therefrom. The container 20 is also the same but does not include the cap 34 or gasket 38 as these are not used with the present in~ention. An adap-20 tor 50 is generally cup-shaped and has a cylindrical tubular portion 52 and a bottom 54 with a central opening 56 therethrough. At the top of the cylindrical portion 52 is a shoulder 58 with a ring portion 60 depending therefrom. The ring portion 60 has internal threads 62 25 that mate with the threaded neck 30 of the container.
Extending upwardly from the shoulder 58 is an externally threaded ring 64. The threads of the ring 64 mate with those of the threaded ring 42 of closure 24 of the dis-penser assembly.
The tube 16 is connected within the neck and handle portions of the dispenser. The upper end of the tube is connected to a fitting 70 such that liquid pumped through the tube is fed through suitable passages within the trigger dispenser as is well-known in the art. The 35 tube is further supported at the lower end of the handle . . ~
CA 022'883' 1999-01-20 portion by means of a bracket 72 and an exten~eA cylin-drical portion 74 to provide ~ealing engagement between the tube and the lower end of the handle portion. The tube 16 fits within the opening 56 at the bottom of the 5 adaptor. The opening is somewhat undersized to provide a tight-fit engagement while allowing the tube to be pushed and pulled through the opening. The tube is preferably of plastic and i5 flexible and somewhat forgiving to allow the tube to be pushed and pulled through the open-10 ing and yet provide a liquid-tight ~eal.
The dispenser assembly and contAiner of Figures 2-4 are sold in the retail stores with the adaptor secured to the container and with the dispenser assembly con-nected to the adaptor as shown in Figures 2 and 4. There 15 is little or no likelihood of the dispenser assembly becoming inadvertently separated from the container as frequently occurred with the prior art arrangement.
To use the dispenser assembly, the dispenser assembly is disconnected from the adaptor, leaving the 20 adaptor secured to the contAiner. The tube is pulled from the contA;ner through the opening 56 while leaving a sufficient length of tube exten~ing into the liquid as shown in Figure 3. Typically, the user operates the dispenser assembly by holding the container in one hand 25 while remotely operating the dispenser with the other to pump liquid from the container and through the nozzle and cap 22 of the dispenser. Preferably, a retainer clip 80 is secured to the tube to act as a stop so that the user does not inadvertently pull all of the tube from the 30 container, but instead leaves a sufficient length of tube within the liquid as shown in Figure 3.
To store the dispenser assembly and container after use, the tube is pushed back through the opening 56 and into the contAiner~ and the dispenser assembly is 35 again connected to the adaptor by screwing the closure 24 CA 022~883~ 1999-01-20 .
onto the threaded ring 64 of the adaptor. The assembly is sealed against leakage both while in use and storage.
Another preferred embodiment of the invention is shown in Figures 5-7. This embodiment is the same as the 5 one shown in Figures 2-4 except as will be expl A i n~ .
The ~prayer assembly of this embodiment also has a handle portion 90 similar to the handle portion 14 of the embodiment of Figures 2-4, but i8 somewhat fihorter. The dispenser assembly of this embodiment also has an adaptor 100 similar to the adaptor 50 of the previous embodiment but is substantially longer. The di~penser assembly of this embodiment also has a tube 110 similar to the tube 16 of the previous embodiment except that it ha~ a pre-formed coil portion 112 hou~ed within a chamber 114 with-15 in the adaptor, the chamber being defined within theadaptor beneath the handle portion 90 of the dispenser.
The upper end of the tube extends into the handle and neck portions of the dispenser and is secured thereto as with the first described embodiment. Also as with the first described embodiment, the tube extends in a tight-fit engagement through an opening at the bottom of the adaptor.
The operation and use of the dispenser assembly and adaptor of this embodiment is similar to that of the first described embodiment, except that when the dispen-ser assembly is disconnected from the adaptor for remote operation of the dispenser, the preformed coil portion 112 of the tube extends as shown in Figure 6, rather than the tube being pulled through the opening at the bottom 30 of the adaptor as with the first described embodiment.
To place the dispenser assembly back in its stored posi-tion, the preformed coil portion is allowed to collapse as in Figures 5 and 7 to be housed in the chamber 114 with the dispenser assembly connected to the adaptor.
35 The primary ad~antage of this embodiment is that the lower portion of the tube in contact with the liquid is CA 022~883~ 1999-01-20 never pulled from the contA;ne~ where it might contact the user, and the portions of the tube that are contacted by the user always remain segregated from the liquid.
Still another preferred embodLment of the pre~ent 5 invention i~ shown in Figures 8-12. Generally, thi~
embodiment is the same as the one shown in Figures 5-7 except as will be explained.
The dispenser assembly of this embodiment has a valve case 120 which is integrally molded as one-piece, 10 and which performs the functions of the handle portion 90, the threaded closure 24, and the fitting 70 of Figure 7. The valve case 120 includes an inverted-cup shaped portion 121 that defines a central cavity 122. The ring portion 42 of this valve case 120, as better shown in 15 Figures 11 and 12, is formed with opposite inwardly pro-jecting tabs 124.
The dispenser as~embly of this embodiment also has an adaptor 126 similar to the adaptor 100 of Figure 7 except that the adaptor 126 is shorter, and the shoulder 20 58 does not include the der~n~ing ring portion 60. As better shown in Figure 12, the adaptor 126 has the top portion 64 formed with bayonet-type provisions 128 which mate with the tabs 124 of the valve case 120. The adap-tor 126 includes a collar 130 that is rotatably mounted 25 on the shoulder 58 and has internal threads that mate with the threaded neck 30 of the container. The adaptor 126 has a vent 131.
This embodiment of the present invention includes a container 132 similar to the container 20 of Figures 1-30 7 except that this container 132 has a crown portion 134that extends at least to the top of the dispensing assem-bly, as shown in Figure 8, and preferably somewhat above the top. Also, the container 132 has the handle portion 32 sloped as shown in Figure 8. The container 132 is 35 provided with the sloping handle portion 32 so that when the container is carried and liquid is in the container, CA 022~883~ 1999-01-20 the liquid will settle in the opposite bottom corner where the inlet to the dip tube 110 i8 located. This insures that during use, while the contAi~er is held in one hand and the sprsyer in the other, the inlet to the 5 dip tube 110 will be below the liquid level, even when the liquid level is drawn low. The crown portion 134 extends as high as or higher than the top of the dispens-ing head 140 to act as protection during shipment, stor-age, and the like. The crown portion 134 is located 10 toward the vertical center of the cont~iner so that the contA i ner and its liquid contents will balance it upside down.
The dispensing assembly of this embodiment has a dispensing head 140. Both the dispensing head 140 and lS the trigger dispenser 12 are well-known in the art.
Although the dispensing head 140 is more particularly shown here, it is merely representative of pump sprayers in general,. and it is to be understood that there are many variations of dispensers that may be used with this 20 invention, dispensers 12 and 140 being only examples.
The dispensing head 140 is an operable assembly which includes a housing 142, a trigger 144, a plunger 146, a spring 148, a spinner as~embly 150, and the nozzle and orifice cap 22. The housing 142 is a molded piece 25 that defines several chambers, including a vertical cham-ber 152, a horizontal chamber 154, a piston chamber 156 and a vent chamber 158 reciprocally receiving a vent pis-ton 160. The wall of the vent chamber has a vent opening 162 which (with the vent opening 131) vents the container 30 when the vent piston is retracted (moves to the left as viewed in Figure 9) upon pulling the trigger 144. The fitting end 70 of the valve case 120 is press fitted into the vertical chamber 152. The trigger 144 has its upper end pivotally supported by the housing 142 by means of 35 oppositely extending lugs (not shown, but which extend into and out of the view of Figure 9) which pivot within .. . . .. . ..
CA 022~883~ 1999-01-20 recesses in spaced side panels of the housing 142. Manu-ally operating the trigger 144 causes the pumping of liquid through the tube from the contAi nPr for ejection out the nozzle and orifice cap 22, as is well-known in 5 the art.
With the bayonet-type connection between the valve case 120 and the adaptor 126, the valve case 120 can either be snapped directly onto the adaptor 126, or con-nected by orienting the dispensing head 140 at 90~ to the 10 container crown 134 and then rotating the dispensing head 140 a quarter turn until the di~pensing head 140 is aligned with the contAiner crown 134 as shown in Figure 8. The dispensing head 140 is mounted to the contAinPr 132 in the proper orientation by virtue of the ad~ust-15 ability provided by the collar 130. Thereafter, thedispensing head 140 is connected and disconnected to the adaptor 126 by means of the bayonet connection so that the dispensing head 140 i8 easily oriented to the same position for storage. The bayonet provisions 128 of the 20 adaptor 126 and the threads of the collar 130 tighten in opposite directions so that rotation of the tabs 124 to disconnect the dispensing head 140 tends to tighten the collar 130 onto the threaded neck 30. The collar 130 and neck 30 may also be adapted to be connected with bayonet 25 type provisions, but preferably at least the valve case 120 and adaptor 126 connect by bayonet type connections for ease and orienting the dispensing head 140.
The operation and use of the dispenser assembly and adaptor 126 of Figures 8-12 are similar to that of 30 the embodiment of Figures 5-7, except that the cavity 122 of the valve case 120 cooperates with the chamber 114 of the adaptor 126 for housing the preformed coils 112 of the tube, as shown in Figures 9 and 10.
While the present invention has been described by 35 reference to specific embodiments, it should be under-stood that modifications and variations of the invention may be constructed without departing from the ficope of the invention defined in the following claims.

Background and Summary of Invention This invention relates to a liquid dispenser assembly, and particularly such an assembly for use with a liquid container and where the dispenser is operated remotely from the container- A tube connects the dispen-5 ser with the container for feeding the liquid to thedispenser. The present invention is an imp~ove---ent over remotely operated dispensers of the type described above, and further includes a unique adaptor secured to the container and to which the dispenser may be connected for 10 sale and storage and disconnected for remote operation.
Liquid dispenser assemblies of the type to which this invention is generally directed are well-known in the art. The dispenser assembly shown in Figure 1 of the drawing is typical of the prior art. The dispenser as-15 sembly 10 of the prior art includes a trigger sprayer 12 CA 022~883~ 1999-01-20 having a neck portion 13, a handle portion 14 and a tube 16. The trigger di~penser 12 is of the type well-known in the art and which is operable by means of a trigger 18 to pump liquid from a suitable container, such as con-5 tainer 20, and out a nozzle and orifice cap 22 of thedispenser. The cap 22 may be fixed or may be ad~ustable to provide a variety of spray patterns, all of which is well-known. The dispenser assembly 10 also includes a threaded closure 24 to connect the handle portion to the 10 neck portion of the dispenser.
The contAinpr 20 is of a type typically found in retail stores and may be of plastic and have a threaded neck 30 and handle portion 32 for carrying and holding the cont~i n~r . When the cont~iner and dispenser assembly 15 are packaged for retail sale in the stores, the container has a threaded cap 34 with a hole 36 in the top. A gas-ket 38 is located between the cap and the threaded neck 30 of the bottle to seal the opening and pre~ent the liquid within the bottle from spilling. When packaged 20 for sale in the store, typically the dispenser assembly, including the trigger sprayer 12, portion 14, and tube 16, are packaged in a sealed plastic bag. The bag has a hole so that the bag containing the dispenser assembly may be hung over the neck 30 of the contAiner with the 25 cap 34 extending through the hole. To use the prior art assembly of Figure 1, the user removes the plastic bag from the container, and removes the dispenser assembly from the plastic bag. The user then inserts the end of the tube 16 through the hole 36 and pierces the gasket 30 38, thus inserting the tube into the liquid within the container. The user holds the container with one hand while operating the trigger sprayer with the other to pump the liquid from the container and out the dispenser.
The container and dispenser assembly of Figure 1 typical-35 ly are used to dispense products such as insecticides,herbicides, and the like.
.. . . .. . . .
CA 022~883~ 1999-01-20 There are several disadvantages associated with the contA i ner and dispenser assembly of Figure 1. Once the gasket is pierced, if the cont~;ner is tipped over during use, the liquid within the contA i ner will leak 5 between the tube and gasket and between the tube and opening 36. Another disadvantage is that the dispenser assembly is awkward to store and there is no provision for sealing the contA i ~r . Still another disadvantage is that the plastic bags contAining the dispenser assemblies 10 frequently become separated from the contAiners in the retail store creating customer confusion and annoyance.
The present invention overcomes these problems.
In accordance with the present invention, there is provided an adaptor that is secured to the neck portion 15 of the contAi~er. While the adaptor may be disconnected from the cont~iner~ it remains connected to it when sold in the stores, when in use, and when the dispenser is stored during non-use. The dispenser and adaptor have means for connecting the dispenser and adaptor together 20 with the tube exten~ing from the dispenser, through the adaptor, and into the container. The dispenser may be disconnected from the adaptor while the adaptor remains secured to the contA i ner ~ for operation of the dispenser remotely from the contAiner. The tube extends through 25 the adaptor in sealing engagement therewith to prevent liquid from entering the interior of the adaptor. Thus, the interior of the adaptor remains dry and sealed from the liquid. When the dispenser assembly is connected to the adaptor, the handle portion of the dispenser extends 30 into the interior of the adaptor and remains dry and out of contact with the liquid. In use where the dispenser is disconnected from the adaptor and operated remotely, the adaptor re~i n~ secured to the container to provide a seal against spilling.
In one preferred embodiment of the invention, the adaptor has a chamber therein. The tube has a preformed CA 022~883~ 1999-01-20 coil portion housed within the chamber with the dispen~er and adaptor connected. The coil portion extends upon disconnecting the dispenser from the adaptor for remote operation of the dispenser. This embodiment has the 5 advantage that the exterior surface of the preformed coiled tube portion which may come in contact with the user during use, is protected from the liquid, it being housed within the adaptor chamber.
These and other advantages of the invention are 10 apparent from the drawing and detailed description to follow.

10 Detailed Description of pref~rred Embo~iments With reference to the drawing, one preferred embodiment of the liquid dispenser assembly with adaptor of the present invention is shown in Figures 2-4. Gener-ally, the dispenser assembly is the same as shown in 15 Figure 1 except that the closure 24 has an outwardly extending shoulder 40 and an internally threaded ring portion 42 depending therefrom. The container 20 is also the same but does not include the cap 34 or gasket 38 as these are not used with the present in~ention. An adap-20 tor 50 is generally cup-shaped and has a cylindrical tubular portion 52 and a bottom 54 with a central opening 56 therethrough. At the top of the cylindrical portion 52 is a shoulder 58 with a ring portion 60 depending therefrom. The ring portion 60 has internal threads 62 25 that mate with the threaded neck 30 of the container.
Extending upwardly from the shoulder 58 is an externally threaded ring 64. The threads of the ring 64 mate with those of the threaded ring 42 of closure 24 of the dis-penser assembly.
The tube 16 is connected within the neck and handle portions of the dispenser. The upper end of the tube is connected to a fitting 70 such that liquid pumped through the tube is fed through suitable passages within the trigger dispenser as is well-known in the art. The 35 tube is further supported at the lower end of the handle . . ~
CA 022'883' 1999-01-20 portion by means of a bracket 72 and an exten~eA cylin-drical portion 74 to provide ~ealing engagement between the tube and the lower end of the handle portion. The tube 16 fits within the opening 56 at the bottom of the 5 adaptor. The opening is somewhat undersized to provide a tight-fit engagement while allowing the tube to be pushed and pulled through the opening. The tube is preferably of plastic and i5 flexible and somewhat forgiving to allow the tube to be pushed and pulled through the open-10 ing and yet provide a liquid-tight ~eal.
The dispenser assembly and contAiner of Figures 2-4 are sold in the retail stores with the adaptor secured to the container and with the dispenser assembly con-nected to the adaptor as shown in Figures 2 and 4. There 15 is little or no likelihood of the dispenser assembly becoming inadvertently separated from the container as frequently occurred with the prior art arrangement.
To use the dispenser assembly, the dispenser assembly is disconnected from the adaptor, leaving the 20 adaptor secured to the contAiner. The tube is pulled from the contA;ner through the opening 56 while leaving a sufficient length of tube exten~ing into the liquid as shown in Figure 3. Typically, the user operates the dispenser assembly by holding the container in one hand 25 while remotely operating the dispenser with the other to pump liquid from the container and through the nozzle and cap 22 of the dispenser. Preferably, a retainer clip 80 is secured to the tube to act as a stop so that the user does not inadvertently pull all of the tube from the 30 container, but instead leaves a sufficient length of tube within the liquid as shown in Figure 3.
To store the dispenser assembly and container after use, the tube is pushed back through the opening 56 and into the contAiner~ and the dispenser assembly is 35 again connected to the adaptor by screwing the closure 24 CA 022~883~ 1999-01-20 .
onto the threaded ring 64 of the adaptor. The assembly is sealed against leakage both while in use and storage.
Another preferred embodiment of the invention is shown in Figures 5-7. This embodiment is the same as the 5 one shown in Figures 2-4 except as will be expl A i n~ .
The ~prayer assembly of this embodiment also has a handle portion 90 similar to the handle portion 14 of the embodiment of Figures 2-4, but i8 somewhat fihorter. The dispenser assembly of this embodiment also has an adaptor 100 similar to the adaptor 50 of the previous embodiment but is substantially longer. The di~penser assembly of this embodiment also has a tube 110 similar to the tube 16 of the previous embodiment except that it ha~ a pre-formed coil portion 112 hou~ed within a chamber 114 with-15 in the adaptor, the chamber being defined within theadaptor beneath the handle portion 90 of the dispenser.
The upper end of the tube extends into the handle and neck portions of the dispenser and is secured thereto as with the first described embodiment. Also as with the first described embodiment, the tube extends in a tight-fit engagement through an opening at the bottom of the adaptor.
The operation and use of the dispenser assembly and adaptor of this embodiment is similar to that of the first described embodiment, except that when the dispen-ser assembly is disconnected from the adaptor for remote operation of the dispenser, the preformed coil portion 112 of the tube extends as shown in Figure 6, rather than the tube being pulled through the opening at the bottom 30 of the adaptor as with the first described embodiment.
To place the dispenser assembly back in its stored posi-tion, the preformed coil portion is allowed to collapse as in Figures 5 and 7 to be housed in the chamber 114 with the dispenser assembly connected to the adaptor.
35 The primary ad~antage of this embodiment is that the lower portion of the tube in contact with the liquid is CA 022~883~ 1999-01-20 never pulled from the contA;ne~ where it might contact the user, and the portions of the tube that are contacted by the user always remain segregated from the liquid.
Still another preferred embodLment of the pre~ent 5 invention i~ shown in Figures 8-12. Generally, thi~
embodiment is the same as the one shown in Figures 5-7 except as will be explained.
The dispenser assembly of this embodiment has a valve case 120 which is integrally molded as one-piece, 10 and which performs the functions of the handle portion 90, the threaded closure 24, and the fitting 70 of Figure 7. The valve case 120 includes an inverted-cup shaped portion 121 that defines a central cavity 122. The ring portion 42 of this valve case 120, as better shown in 15 Figures 11 and 12, is formed with opposite inwardly pro-jecting tabs 124.
The dispenser as~embly of this embodiment also has an adaptor 126 similar to the adaptor 100 of Figure 7 except that the adaptor 126 is shorter, and the shoulder 20 58 does not include the der~n~ing ring portion 60. As better shown in Figure 12, the adaptor 126 has the top portion 64 formed with bayonet-type provisions 128 which mate with the tabs 124 of the valve case 120. The adap-tor 126 includes a collar 130 that is rotatably mounted 25 on the shoulder 58 and has internal threads that mate with the threaded neck 30 of the container. The adaptor 126 has a vent 131.
This embodiment of the present invention includes a container 132 similar to the container 20 of Figures 1-30 7 except that this container 132 has a crown portion 134that extends at least to the top of the dispensing assem-bly, as shown in Figure 8, and preferably somewhat above the top. Also, the container 132 has the handle portion 32 sloped as shown in Figure 8. The container 132 is 35 provided with the sloping handle portion 32 so that when the container is carried and liquid is in the container, CA 022~883~ 1999-01-20 the liquid will settle in the opposite bottom corner where the inlet to the dip tube 110 i8 located. This insures that during use, while the contAi~er is held in one hand and the sprsyer in the other, the inlet to the 5 dip tube 110 will be below the liquid level, even when the liquid level is drawn low. The crown portion 134 extends as high as or higher than the top of the dispens-ing head 140 to act as protection during shipment, stor-age, and the like. The crown portion 134 is located 10 toward the vertical center of the cont~iner so that the contA i ner and its liquid contents will balance it upside down.
The dispensing assembly of this embodiment has a dispensing head 140. Both the dispensing head 140 and lS the trigger dispenser 12 are well-known in the art.
Although the dispensing head 140 is more particularly shown here, it is merely representative of pump sprayers in general,. and it is to be understood that there are many variations of dispensers that may be used with this 20 invention, dispensers 12 and 140 being only examples.
The dispensing head 140 is an operable assembly which includes a housing 142, a trigger 144, a plunger 146, a spring 148, a spinner as~embly 150, and the nozzle and orifice cap 22. The housing 142 is a molded piece 25 that defines several chambers, including a vertical cham-ber 152, a horizontal chamber 154, a piston chamber 156 and a vent chamber 158 reciprocally receiving a vent pis-ton 160. The wall of the vent chamber has a vent opening 162 which (with the vent opening 131) vents the container 30 when the vent piston is retracted (moves to the left as viewed in Figure 9) upon pulling the trigger 144. The fitting end 70 of the valve case 120 is press fitted into the vertical chamber 152. The trigger 144 has its upper end pivotally supported by the housing 142 by means of 35 oppositely extending lugs (not shown, but which extend into and out of the view of Figure 9) which pivot within .. . . .. . ..
CA 022~883~ 1999-01-20 recesses in spaced side panels of the housing 142. Manu-ally operating the trigger 144 causes the pumping of liquid through the tube from the contAi nPr for ejection out the nozzle and orifice cap 22, as is well-known in 5 the art.
With the bayonet-type connection between the valve case 120 and the adaptor 126, the valve case 120 can either be snapped directly onto the adaptor 126, or con-nected by orienting the dispensing head 140 at 90~ to the 10 container crown 134 and then rotating the dispensing head 140 a quarter turn until the di~pensing head 140 is aligned with the contAiner crown 134 as shown in Figure 8. The dispensing head 140 is mounted to the contAinPr 132 in the proper orientation by virtue of the ad~ust-15 ability provided by the collar 130. Thereafter, thedispensing head 140 is connected and disconnected to the adaptor 126 by means of the bayonet connection so that the dispensing head 140 i8 easily oriented to the same position for storage. The bayonet provisions 128 of the 20 adaptor 126 and the threads of the collar 130 tighten in opposite directions so that rotation of the tabs 124 to disconnect the dispensing head 140 tends to tighten the collar 130 onto the threaded neck 30. The collar 130 and neck 30 may also be adapted to be connected with bayonet 25 type provisions, but preferably at least the valve case 120 and adaptor 126 connect by bayonet type connections for ease and orienting the dispensing head 140.
The operation and use of the dispenser assembly and adaptor 126 of Figures 8-12 are similar to that of 30 the embodiment of Figures 5-7, except that the cavity 122 of the valve case 120 cooperates with the chamber 114 of the adaptor 126 for housing the preformed coils 112 of the tube, as shown in Figures 9 and 10.
While the present invention has been described by 35 reference to specific embodiments, it should be under-stood that modifications and variations of the invention may be constructed without departing from the ficope of the invention defined in the following claims.
