Abstract
An applicator (10) for a semi-solid material (15), such as lip balm, with an elastomeric material base cap (12) has an interior tube (31) long enough to cooperate with other structures of the applicator to allow ejection of the plunger (20) associated with the lip balm and its shaft (21) by continued depression of the base cap. This allows easy replacement of the lip balm in the applicator when the original is used up. The applicator also has a tubular housing (14) with interior guide hub (39) with ribs (42) configured and positioned to preclude spinning of the shaft of the plunger (20) mounting the lip balm. A dispenser (50) for flowable material such as lotion comprises a bellows (52) mounted in a housing (51) with an elastomeric material base cap (54) at one end and an end cap (62) at the other.

CROSS REFERENCE TO RELATED APPLICATION
This application is based upon, and claims the priority of, U S Provisional Application SN 62/285,570 filed November 2, 2015, the disclosure of which is hereby incorporated by reference herein.
BACKGROUND AND SUMMARY OF THE INVENTION
The disclosure of PCT/IB2015/053286 (now U S National Phase application SN
15/330,500 filed September 28, 2016) is hereby incorporated by reference herein. That application relates to an applicator for semi-solid materials, such as lip balm, that incorporates many novel features including, but not limited to, an elastomeric material base cap, and a plunger for holding the semi-solid material, which plunger is reciprocal within and with respect to a housing.
According to the present invention, a number of additional features and/or enhanced functionalities are provided for a material dispenser/applicator, based at least in part on the application of said PCT application. Also, a novel flowable material dispenser is disclosed.
According to one aspect of the present invention there is provided an applicator for a semi-solid material such as lip balm. The applicator comprises: A generally tubular housing having first and second ends. A plunger to which is mounted semi-solid material extending exteriorly of the housing first end, the plunger including a shaft. And an elastomeric material base cap mounted to the second end of the housing and having an interior structure to which the shaft is connected. The structures are configured so that by continued depression the elastomeric base cap is movable to a position which induces separation between surface manifestations on the shaft and interior structure of the base cap which provides ejection of the plunger and its shaft from the housing.
The elastomeric base cap interior structure to which the shaft is connected preferably comprises a tubular portion of the base cap. An end cap (preferably transparent or translucent) is releasably connected to the housing at the first end thereof for covering the semi-solid material. In view of the desired functionality of the applicator of the invention the elastomeric base cap should have a durometer of about 45-55 (about 50 is ideal) on the Shore A scale, not the broader range of 40-70 in said PCT application.
The applicator preferably further comprises an apertured abutment within the housing through which the plunger shaft reciprocates and which acts as a stop for the interior structure of the base cap during ejection of the plunger shaft from the housing. The housing desirably has an interior guide hub (or apertured abutment) with ribs configured and positioned to preclude spinning of the plunger shaft.
In one embodiment of the invention the elastomeric material base cap is a bistable element which moves from a first stable configuration in which the semi-solid material is primarily within the housing to, after removal of the end cap and manual actuation thereof a second stable configuration in which the semi-solid mass is substantially completely exterior of the housing, and upon further manual actuation of the elastomeric material base cap while in the second stable configuration moves to a third position whereby the plunger shaft is ejected from contact with the elastomeric base cap. In another embodiment the base cap merely moves from its normal position to the eject position, and is not bistable.
According to another aspect of the invention, an applicator for a semi-solid material is provided which comprises: A generally tubular housing having first and second ends. A
plunger to which is mounted scmi-solid material extending exteriorly of the housing first end, the plunger including a shaft. And an interior guide hub with ribs configured and positioned to preclude spinning of the plunger shaft. The particular elastomeric material end cap as described above may also be utilized.
According to another aspect of the invention there is provided a method of using the applicator as described above to eject a plunger having semi-solid material which is primarily used up, and replacing it with another, replacement, plunger having a fresh supply of semi-solid material by inserting the shaft of the replacement plunger into operative association with the interior structure/tube of the elastomeric material end cap.
According to yet another aspect of the invention there is provided a dispenser for dispensable material which comprises: A generally tubular housing having first and second ends. A dispensable material containing or supporting structure including a shaft having a first surface manifestation thereon; an elastomeric material base cap at the second end of the housing and having a generally central structure with a second surface manifestation releasably operatively cooperating with the first surface manifestation. Upon depression thereof, the elastomeric material base cap operatively moves to a position which moves the shaft to provide access to dispensable material from the dispensable material containing or supporting structure at the first end of the housing. And a stop mechanism within the housing for stopping movement of the generally central structure of the base cap so that upon continued depression of the base cap the first and second surface manifestations disconnect so that said dispensable material containing or supporting structure is removable from the housing and replaceable by a fresh dispensable material containing or supporting structure.

DETAILED DESCRIPTION OF THE DRAWINGS
The applicator 10 according to the invention in FIGURES 1-4 is very similar to the applicator in said PCT application, including a screw-on end cap 11, an elastomeric material base cap 12, a tubular housing 14, and a reciprocal plunger 20 which mounts a semi-solid material (such as lip balm, shown in dotted line at 15) which has a plunger shaft 21. The housing 14 has a first end 16 and an opposite second end 17. The components may be made of the same materials as in said PCT application.
In the FIGURES 1-4 applicator 10, the central tube 31 (comparable to the central tubes 31, 131 in said PCT application) which releasably connects the base cap 12 to the end 22 of the plunger shaft 21 opposite the semi-solid material 15 is longer than that in the PCT
application. In one practical embodiment the central tube 31 is about 2-3 mm (e. g. about 2.5 mm) longer. This added length allows the applicator to function so that the plunger 20 and shaft 21 may be "ejected" from the housing 14, allowing ready use of replacement cartridges once all of the semi-solid material 15 has been used up.
The end 22 of the plunger shaft 21 has a first surface manifestation ¨ in the drawing shown at 24 as a circumferential depression in the end 22 of shaft 21 ¨ which operatively cooperates with a second surface manifestation 25 on the tube 31, element 25 best seen in
1-4;
FIGURE 9 is a side cross-sectional view of the housing of FIGURES 1-4 & 8 rotated ninety degrees from the view in FIGURE 1;

FIGURE 11 is a side cross-sectional view of the dispenser of FIGURE 10 assembled and with the end cap open to allow dispensing of flowable material;
FIGURE 12 is a view like that of FIGURE 11 with the base cap slightly depressed to dispense flowable material from the bellows; and FIGURE 13 is a view like that of FIGURE 12 only showing the end cap completely removed, the bellows depleted, and the base cap moved to a position whereby the bellows shaft is detached from the base cap so that the bellows and shaft may be ejected and replaced by a replacement fresh bellows and shaft.
DETAILED DESCRIPTION OF THE DRAWINGS
The applicator 10 according to the invention in FIGURES 1-4 is very similar to the applicator in said PCT application, including a screw-on end cap 11, an elastomeric material base cap 12, a tubular housing 14, and a reciprocal plunger 20 which mounts a semi-solid material (such as lip balm, shown in dotted line at 15) which has a plunger shaft 21. The housing 14 has a first end 16 and an opposite second end 17. The components may be made of the same materials as in said PCT application.
In the FIGURES 1-4 applicator 10, the central tube 31 (comparable to the central tubes 31, 131 in said PCT application) which releasably connects the base cap 12 to the end 22 of the plunger shaft 21 opposite the semi-solid material 15 is longer than that in the PCT
application. In one practical embodiment the central tube 31 is about 2-3 mm (e. g. about 2.5 mm) longer. This added length allows the applicator to function so that the plunger 20 and shaft 21 may be "ejected" from the housing 14, allowing ready use of replacement cartridges once all of the semi-solid material 15 has been used up.
The end 22 of the plunger shaft 21 has a first surface manifestation ¨ in the drawing shown at 24 as a circumferential depression in the end 22 of shaft 21 ¨ which operatively cooperates with a second surface manifestation 25 on the tube 31, element 25 best seen in
4
5 FIGURES 1 & 4. The second surface manifestation 25 is in the form of a circumferential projection which fits in the depression 24 to hold the elements 21, 31 together during normal operation, and until separation thereof is desired. While the manifestations 24, 25 as illustrated are preferred any other surface manifestations that perform the intended function of releasably attaching the shaft 21 to the base cap 12 may be provided.
Also, in the applicator 10 according to the invention it has been found that the elastomeric material of the base cap 12 should have a durometer of about 45-55 (about 50 is highly desirable) on the Shore A scale, rather than 40-70 as in the PCT
application. A
durometer of about 50 allows the base cap 12 to still be bistable yet effectively be moved to a third, eject, position, during which the surface manifestations 24, 25 detach.
Once the end cap 11 is removed (preferably by unscrewing it, as in FIGURES 1-4), the semi-solid material 15 associated with the plunger 20 is exposed but typically much of it does not extend out the first end 16 of the housing 14, as seen in FIGURE 2. A
human user can use her/his finger to engage the exterior surface 19 (which may be considered an eject button) of the base cap 12 and push it from the first stable position shown in FIGURE 2 to a second stable position shown in FIGURE 3 in which substantially all of the material 15 is exterior of the first end of the housing 14. That is, as in said PCT
application, the cap 12 is bistable.
During movement of base cap 12 from the first position of FIGURE 2 to the second .. position of FIGURE 3 the plunger shaft 21 is guided by the centrally located guide hub 39, which can also be considered an apertured abutment. In the position of the base cap 12 in FIGURE 3 the central tube 31 engages the centrally located guide hub 39 which guides reciprocation of the shaft 21, stopping movement of the tube 31.
If depression of base cap 12 by a user's finger is continued from the position of FIGURE 3 to the position of FIGURE 4 then the plunger shaft 21 end 22 will be detached from the base cap 12 tube 31 because the plunger shaft 21 will keep moving but the base cap 12 will be stopped by the hub 39. Therefore the shaft 21 and plunger 20 attached thereto, as in FIGURE 4, will be separated from the rest of the applicator 10 since the surface manifestations 24, 25 will be detached from one another so that a new cartridge containing a new plunger 20 with fresh semi-solid material 15 attached, and plunger shaft 21, may replace the removed one by inserting the new shaft end 22 into the central tube 31 when the base cap 12 is in the FIGURE 4 position. When the replacement plunger is inserted the elastomeric tube 31 of the elastomeric material base cap 12 is deflected so that the surface manifestations 24, 25 engage each other and the new shaft 21 is attached to the base cap 12.
It is noted that during the ejection process, that is moving from the second position of FIGURE 3 to the third, eject, position of FIGURE 4, typically the first end 16 of the housing 14 will be angled (or completely facing) downwardly so that gravity assists in the detachment of the old plunger 20 from the base cap 12.
During insertion of the new plunger with fresh lip balm or the like 15 desirably the user will hold the base cap 12 in the FIGURE 4 position while the user (preferably but not necessarily with the end cap 11 over the material 15 but engaging the circumferential periphery 23 of the top of the plunger 20 and not the material 15 itself) pushes the end 22 of shaft 21 into operative association with the central tube 31 of the base cap 12. Once the shaft end 22 is seated, the user removes her/his finger from the exterior 19 of the base cap 12, and continues to move the end cap 11 toward the housing 14, and ultimately screws it in place so that the end cap 12 and plunger 20 are in the positions illustrated in FIGURE
2.
The applicator 110 of P1UURES 5-7 is similar to that of FIGURES 1-4 only the housing 114 and shaft 121 are shorter and the end cap 112 is not bistable.
Components comparable to those of the FIGURES 1-4 embodiment are shown by the same reference numeral only preceded by a "1."
In FIGURE 6 the base cap 112 is in its normal position (once the end cap 111 is removed) with the lip balm 115 extending outwardly from the first end 116 of the housing 114. Once the lip balm 115 has been substantially depleted (as shown schematically in FIGURE 7) the user pushes on exterior surface 119 of the base cap 112 to move it to the eject position. During this sequence to the position illustrated in FIGURE 7 the surface manifestations 124, 125, respectively, on the end 122 of shaft 121 and central tube 131 of base cap 112, respectively, detach from each other since the tube 131 movement is stopped by the apertured abutment 139. Replacement of a new plunger 120 with fresh material 115 is as described above with respect to the FIGURES 1-4 embodiment.
Preferably, as shown most clearly in FIGURES 8 & 9, the housing 14, includes interior ribs 42 associated with the guide hub/ apertured abutment 39 to prevent the plunger shaft 21 from spinning; otherwise spinning might occur, such as when a seal (if it exists) between the semi-solid material 15 and the end cap 11 is broken when the end cap 11 is unscrewed from the housing 14 first end 16. The ribs 42 engage portions of the perimeter of the plunger (which may have the configuration of the plunger 121 illustrated in FIGURE 7 of said PCT application) to prevent it from spinning/rotating.
The housing 114 may have ribs 42 also, as described above, the housing 114 substantially the same as housing 14 except that it is shorter.
Also, in the applicator 10 according to the invention it has been found that the elastomeric material of the base cap 12 should have a durometer of about 45-55 (about 50 is highly desirable) on the Shore A scale, rather than 40-70 as in the PCT
application. A
durometer of about 50 allows the base cap 12 to still be bistable yet effectively be moved to a third, eject, position, during which the surface manifestations 24, 25 detach.
Once the end cap 11 is removed (preferably by unscrewing it, as in FIGURES 1-4), the semi-solid material 15 associated with the plunger 20 is exposed but typically much of it does not extend out the first end 16 of the housing 14, as seen in FIGURE 2. A
human user can use her/his finger to engage the exterior surface 19 (which may be considered an eject button) of the base cap 12 and push it from the first stable position shown in FIGURE 2 to a second stable position shown in FIGURE 3 in which substantially all of the material 15 is exterior of the first end of the housing 14. That is, as in said PCT
application, the cap 12 is bistable.
During movement of base cap 12 from the first position of FIGURE 2 to the second .. position of FIGURE 3 the plunger shaft 21 is guided by the centrally located guide hub 39, which can also be considered an apertured abutment. In the position of the base cap 12 in FIGURE 3 the central tube 31 engages the centrally located guide hub 39 which guides reciprocation of the shaft 21, stopping movement of the tube 31.
If depression of base cap 12 by a user's finger is continued from the position of FIGURE 3 to the position of FIGURE 4 then the plunger shaft 21 end 22 will be detached from the base cap 12 tube 31 because the plunger shaft 21 will keep moving but the base cap 12 will be stopped by the hub 39. Therefore the shaft 21 and plunger 20 attached thereto, as in FIGURE 4, will be separated from the rest of the applicator 10 since the surface manifestations 24, 25 will be detached from one another so that a new cartridge containing a new plunger 20 with fresh semi-solid material 15 attached, and plunger shaft 21, may replace the removed one by inserting the new shaft end 22 into the central tube 31 when the base cap 12 is in the FIGURE 4 position. When the replacement plunger is inserted the elastomeric tube 31 of the elastomeric material base cap 12 is deflected so that the surface manifestations 24, 25 engage each other and the new shaft 21 is attached to the base cap 12.
It is noted that during the ejection process, that is moving from the second position of FIGURE 3 to the third, eject, position of FIGURE 4, typically the first end 16 of the housing 14 will be angled (or completely facing) downwardly so that gravity assists in the detachment of the old plunger 20 from the base cap 12.
During insertion of the new plunger with fresh lip balm or the like 15 desirably the user will hold the base cap 12 in the FIGURE 4 position while the user (preferably but not necessarily with the end cap 11 over the material 15 but engaging the circumferential periphery 23 of the top of the plunger 20 and not the material 15 itself) pushes the end 22 of shaft 21 into operative association with the central tube 31 of the base cap 12. Once the shaft end 22 is seated, the user removes her/his finger from the exterior 19 of the base cap 12, and continues to move the end cap 11 toward the housing 14, and ultimately screws it in place so that the end cap 12 and plunger 20 are in the positions illustrated in FIGURE
2.
The applicator 110 of P1UURES 5-7 is similar to that of FIGURES 1-4 only the housing 114 and shaft 121 are shorter and the end cap 112 is not bistable.
Components comparable to those of the FIGURES 1-4 embodiment are shown by the same reference numeral only preceded by a "1."
In FIGURE 6 the base cap 112 is in its normal position (once the end cap 111 is removed) with the lip balm 115 extending outwardly from the first end 116 of the housing 114. Once the lip balm 115 has been substantially depleted (as shown schematically in FIGURE 7) the user pushes on exterior surface 119 of the base cap 112 to move it to the eject position. During this sequence to the position illustrated in FIGURE 7 the surface manifestations 124, 125, respectively, on the end 122 of shaft 121 and central tube 131 of base cap 112, respectively, detach from each other since the tube 131 movement is stopped by the apertured abutment 139. Replacement of a new plunger 120 with fresh material 115 is as described above with respect to the FIGURES 1-4 embodiment.
Preferably, as shown most clearly in FIGURES 8 & 9, the housing 14, includes interior ribs 42 associated with the guide hub/ apertured abutment 39 to prevent the plunger shaft 21 from spinning; otherwise spinning might occur, such as when a seal (if it exists) between the semi-solid material 15 and the end cap 11 is broken when the end cap 11 is unscrewed from the housing 14 first end 16. The ribs 42 engage portions of the perimeter of the plunger (which may have the configuration of the plunger 121 illustrated in FIGURE 7 of said PCT application) to prevent it from spinning/rotating.
The housing 114 may have ribs 42 also, as described above, the housing 114 substantially the same as housing 14 except that it is shorter.
6 FIGURES 8 and 9 show four ribs 42 symmetrically positioned around the interior circumference of the circular opening in the guide hub 39 and show the "upper"
(closest to the base cap) faces 43 thereof slanted downwardly in FIGURE 9 (so that the ribs 42 themselves have a generally triangular cross-section). However other numbers (e. g. three or five) and/or configurations in cross-section (e. g. quadrate, multiple, or random) may be provided.
FIGURES 10-13 show a different type of material dispenser 50 than in the other FIGURES but using the same general concepts of a tubular housing, an end cap, and an elastomeric material base cap. Different numerals will be used than related to the other FIGURES.
The dispenser 50 is provided for dispensing a flowable material (e. g.
liquid), such as (but not limited to) lotions, eye drops or other medical or medicinal fluids, flavor concentrates for flavoring ingestible liquids like water, toothpaste, and lubricants. Located interiorly of a generally tubular housing 51 is a bellows 52 made of generally conventional bellows elastomeric material, operatively connected at a closed end thereof through a connected (preferably integral) shaft 53 to a central interior tube 57 of an elastomeric base cap 56 at the second end 55 of the housing 51. The base cap 56 preferably has a central tube 57 just like the tubes 31, 131 in the other embodiments, and the first surface manifestation 58 on the shaft 53 and the second surface manifestation 59 in the tube 57 are just like the surface manifestations 24, 124, 25, 125 in the other embodiments.
Interior of the housing 51 is an interior guide hub/apertured abutment 61 with an interior opening 62 defined by a collar which guides reciprocation of the shaft 53.
The end of the bellows 52 opposite the shaft 53 has a conventional dispensing nozzle 64 therein, which will be dimensioned depending upon the particular flowable material to be dispensed and which may include a conventional one-way valve.
The first end 66 of the housing 51, opposite the elastomeric base cap 56, may be closed off by an end cap 67. In the preferred embodiment illustrated in FIGURES 10-13 the end cap 67 contains a hollow generally tubular first portion 68 which has external screw threads 69 (best seen in FIGURES 10 & 13) which screw onto conventional complementary interior screw threads 70 (FIGURE 10) on the first end 66 of the housing 51.
The end cap 67 also includes a solid terminating second portion 72 which is connected by a living hinge 73 (FIGURES 11 & 12) to the first portion 68. Any suitable closure (such as a clip, magnet, snap, etc.) may be provided for holding the second portion 72 to the first portion 68 when the
(closest to the base cap) faces 43 thereof slanted downwardly in FIGURE 9 (so that the ribs 42 themselves have a generally triangular cross-section). However other numbers (e. g. three or five) and/or configurations in cross-section (e. g. quadrate, multiple, or random) may be provided.
FIGURES 10-13 show a different type of material dispenser 50 than in the other FIGURES but using the same general concepts of a tubular housing, an end cap, and an elastomeric material base cap. Different numerals will be used than related to the other FIGURES.
The dispenser 50 is provided for dispensing a flowable material (e. g.
liquid), such as (but not limited to) lotions, eye drops or other medical or medicinal fluids, flavor concentrates for flavoring ingestible liquids like water, toothpaste, and lubricants. Located interiorly of a generally tubular housing 51 is a bellows 52 made of generally conventional bellows elastomeric material, operatively connected at a closed end thereof through a connected (preferably integral) shaft 53 to a central interior tube 57 of an elastomeric base cap 56 at the second end 55 of the housing 51. The base cap 56 preferably has a central tube 57 just like the tubes 31, 131 in the other embodiments, and the first surface manifestation 58 on the shaft 53 and the second surface manifestation 59 in the tube 57 are just like the surface manifestations 24, 124, 25, 125 in the other embodiments.
Interior of the housing 51 is an interior guide hub/apertured abutment 61 with an interior opening 62 defined by a collar which guides reciprocation of the shaft 53.
The end of the bellows 52 opposite the shaft 53 has a conventional dispensing nozzle 64 therein, which will be dimensioned depending upon the particular flowable material to be dispensed and which may include a conventional one-way valve.
The first end 66 of the housing 51, opposite the elastomeric base cap 56, may be closed off by an end cap 67. In the preferred embodiment illustrated in FIGURES 10-13 the end cap 67 contains a hollow generally tubular first portion 68 which has external screw threads 69 (best seen in FIGURES 10 & 13) which screw onto conventional complementary interior screw threads 70 (FIGURE 10) on the first end 66 of the housing 51.
The end cap 67 also includes a solid terminating second portion 72 which is connected by a living hinge 73 (FIGURES 11 & 12) to the first portion 68. Any suitable closure (such as a clip, magnet, snap, etc.) may be provided for holding the second portion 72 to the first portion 68 when the
7 dispenser 50 is in the non-dispensing position with the elements 68, 72 connected as in FIGURES 10& 13.
In operation of the dispenser 50, the end cap 67 second portion 72 is detached from the first portion 68, and pivoted away via the living hinge 73 to the relative positions illustrated in FIGURES 11 & 12. To dispense the flowable material within the bellows 52 the user depresses the elastomeric material base cap 56, causing the bellows 52 to compress and the flowable material therein to be dispensed through the nozzle 64. FIGURE 11 shows the dispenser 50 in a position just before depression of the elastomeric material base cap 56 and FIGURE 12 shows the bellows 52 partially compressed in response to depression of the base cap 56.
Once the bellows 52 is substantially empty the end cap 67 is unscrewed (FIGURE
13) from the housing 51. Then depression of the end cap 56 is continued to the position of FIGURE 13 wherein movement of the tube 57 is stopped by the abutment 61. This causes detachment of the surface manifestations 58, 59 so that the shaft 53 and bellows 52 are easily removed from the housing 51 just as for the other embodiments in FIGURES 4 &
7. A new bellows 52 can be inserted, the shaft 53 thereof moved into operative engagement with the central interior tube 57 of the base cap 56 so that the surface manifestations 58, 59 operatively engage so that the base cap 56 is operatively connected to the new bellows 52.
The entire dispenser 50 is preferably made of dishwasher safe and eco-friendly plastic.
It will thus be seen that there are generic similarities between the various embodiments, comprising in general a dispenser for dispensable material (a semi-solid like lip balm or a flowable material like lotion) having a dispensable material containing or supporting structure (20, 52) including a shaft (21, 53) having a first surface manifestation thereon (24, 58); an elastomeric material base cap (12, 56) having a generally central structure (31, 57) with a second surface manifestation (25, 59) releasably operatively cooperating with the first surface manifestation (24, 58); upon depression thereof, the elastomeric material base cap (12, 56) operatively moves to a position which moves the shaft (21, 53) to provide access to dispensable material from the dispensable material containing or supporting structure (20, 52) at the first end (16, 70) of the housing (14, 51); and a stop mechanism (39) within the housing (14, 51) for stopping movement of the generally central structure (31, 57) of the base cap so that upon continued depression of the base cap the first and second surface manifestations (24, 25; 58, 59) disconnect so that the dispensable material
In operation of the dispenser 50, the end cap 67 second portion 72 is detached from the first portion 68, and pivoted away via the living hinge 73 to the relative positions illustrated in FIGURES 11 & 12. To dispense the flowable material within the bellows 52 the user depresses the elastomeric material base cap 56, causing the bellows 52 to compress and the flowable material therein to be dispensed through the nozzle 64. FIGURE 11 shows the dispenser 50 in a position just before depression of the elastomeric material base cap 56 and FIGURE 12 shows the bellows 52 partially compressed in response to depression of the base cap 56.
Once the bellows 52 is substantially empty the end cap 67 is unscrewed (FIGURE
13) from the housing 51. Then depression of the end cap 56 is continued to the position of FIGURE 13 wherein movement of the tube 57 is stopped by the abutment 61. This causes detachment of the surface manifestations 58, 59 so that the shaft 53 and bellows 52 are easily removed from the housing 51 just as for the other embodiments in FIGURES 4 &
7. A new bellows 52 can be inserted, the shaft 53 thereof moved into operative engagement with the central interior tube 57 of the base cap 56 so that the surface manifestations 58, 59 operatively engage so that the base cap 56 is operatively connected to the new bellows 52.
