People have found it helpful to split or cut pills. For example, they may do this to reduce the dosage or to make a pill easier to swallow. Typical pill splitters have mechanisms to allow a user to manually press a single blade against the pill. Other pill splitters have used a pair of blades that a user can squeeze together to split the pill.
Whatever the advantages of previous pill splitters, they have neither recognized the need for the features of the pill splitters described and claimed herein, nor the advantages produced by such features and pill splitters.
According to one aspect, a pill can be positioned on a portion of a first housing of a pill splitter, with the pill being positioned above a first blade of the pill splitter that is secured to the first housing. With the pill positioned on the portion of the first housing, a second housing of the pill splitter can be manually pushed downward toward a bottom of the first housing from an open position toward a closed position in which one or both of the second housing and the first housing comprise one or more surfaces that define a pill container space that contains the pill. A second blade can be secured to the second housing, and the pushing of the second housing downward toward the closed position can split the pill by bringing the second blade toward the first blade with both a cutting edge of the second blade and a cutting edge of the first blade cutting into the pill.
According to another aspect, a pill splitter can include a first housing and a second housing. The second housing can be configured to slide along the first housing in a linear direction between a closed position in which the second housing is slid onto the first housing with one or both of the second housing and the first housing defining a pill container space and an open position in which the second housing is fully detached from the first housing. The pill splitter can further include a first blade secured to the first housing, with the first blade being a different material than material of the first housing that is proximate to the first blade. A second blade can be secured to the second housing, with the second blade being a different material than material of the second housing that is proximate to the second blade. The pill splitter can be configured so that the linear sliding of the second housing toward the closed position brings the second blade toward the first blade.
According to yet another aspect, a pill splitter can include a blade and a first housing. The first housing can include a foundation to which the blade is secured. The first housing can also include a platform that is moveable relative to the blade, such that the platform is moveable between a hiding position in which the platform hides the blade and an exposing position in which the platform exposes the blade. The first housing can also include a spring device that is integrally formed with at least one of the foundation or the platform, with the spring device biasing the platform relative to the foundation toward the hiding position.
This Summary is provided to introduce a selection of concepts in a simplified form. The concepts are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Similarly, the invention is not limited to implementations that address the particular techniques, tools, environments, disadvantages, or advantages discussed in the Background, the Detailed Description, or the attached drawings.
The description and drawings may refer to the same or similar features in different drawings with the same reference numbers. Also, in the drawings when multiple features in a figure are referenced by the same reference number in the text, only a single reference line and number are included in the figure.
Some previous pill splitters have been configured to allow a user to push downwardly on the on the pill splitter to cut the pill. Such pill splitters have typically included a pushing part that pushes against the pill from either the top or the bottom to push the pill against a cutting edge of a blade positioned opposite the pushing part, so that the single blade cuts into the pill and splits the pill. Other pill splitters have included blades on opposite sides of a pill where the pill splitters are configured for a user to squeeze the blades together (such as between a finger and thumb) with simple mechanisms (such as mechanisms like clippers with opposing blades) or to actuate the blades with complex mechanisms that are moved using handles or motors. It has been found that advantageous results can be achieved with a pill splitter that is configured for pill splitting to be effected by applying downward pressure, such as forcing the pill splitter against a table or other supporting surface, to press cutting edges of opposing blades against the pill. The combination of allowing for this downward pushing along with the use of multiple blades provides an easy-to-use pill cutter that does not need complex mechanisms for its operation. It has also been found that a pill splitter can include additional advantageous features, such as a fully removeable lid that can include an upper blade and can be configured to cut a pill as the lid is slid onto a device. For example, a second housing may be configured to slide onto a first housing in a linear direction to cut or split a pill. As used herein, a housing is a structure that supports one or more parts, such as supporting a blade. One or more housings may also form a case or enclosure for holding pills in some examples. As another example, a pill splitter can include a support or platform that can be configured to support a pill and to be moved to expose or hide a blade, wherein the platform can be biased toward a blade-hiding position with a spring device that is integrally formed with one or both of the platform or a foundation of the pill splitter. Besides these features, other features of the pill splitters and pill splitting methods discussed herein can produce advantageous results either alone or in combination with other features.
The subject matter defined in the appended claims is not necessarily limited to the benefits described herein. A particular implementation of the invention may provide all, some, or none of the benefits described herein. Also, although operations for the various techniques such as use of pill splitters are described herein in a particular, sequential order for the sake of presentation, it should be understood that this manner of description encompasses rearrangements in the order of operations, unless a particular ordering is required. For example, operations described sequentially may in some cases be rearranged or performed concurrently.
A. First Pill Splitter Structure
Referring now to
The foundation 112 can also include a wall 120 extending up from a periphery of the foundation floor 116, with the wall 120 and the stand 118 each extending around the periphery of the foundation floor 116. An upper surface of the stand 118 can extend out from the base of the wall 120 to form a ledge 122 that faces upwardly and extends around the outside of the bottom of the wall 120. A front side 124 of the wall 120 can define an access cutout 126 that can extend downwardly from a top of the wall. Additionally, the foundation 112 can include a pair of spring positioners 130, with the spring positioners 130 being hollow truncated cones that narrow as they extend up from opposite ends of the foundation floor 116, with each spring positioner 130 extending up from one of the semi-circular areas of the foundation floor 116.
Between the spring positioners 130, a blade support 132 can extend from the front of the wall 120 of the foundation 112 to a rear of the wall 120 and can extend up from the foundation floor 116. For example, the blade support 132 can be protrusion such as a wall. The wall 120 can define a pair of lid engagement recesses 134 extending into an exterior surface of the wall 120 on opposite ends (left and right ends) of the wall 120, with the lid engagement recesses 134 being positioned beyond the spring positioners 130.
Additionally, an aperture 136 can extend downwardly into each of the left and right ends of the foundation floor 116 and can extend outwardly to each define a platform engaging surface 138 that faces downwardly.
A bottom portion of a first blade 140 can be seated within a slot in the blade support 132 so that the first blade 140 can be fixed and secured to the foundation 112. The first blade 140 can extend up from the blade support 132 and include a wedge that narrows to form a cutting edge 142, which can face upwardly and extend horizontally in a front-to-rear direction.
A spring device 150, which can be considered part of the first housing 110, can include a pair of springs, such as with one compression spring positioned around each of the spring positioners 130, with each spring being seated against the foundation floor 116 and extending upwardly above the spring positioner 130 upon which it is seated.
Referring to
The platform 160 can further include a pair of top stops 176, which can be positioned forward of the fixed pill positioning walls 170 on each side of the blade slot 164. Each top stop 176 can be a protrusion that extends up from the top surface of the platform floor 162. Additionally, the platform 160 can include a pair of bottom stops 178 that can also be positioned forward of the fixed pill positioning walls 170 on each side of the blade slot 164. The bottom stops 178 can be protrusions that extend down from the bottom surface of the platform floor 162. Between each bottom stop 178 and the blade slot 164, a guide ridge 182 can extend down from the bottom surface of the platform floor 162. Each guide ridge 182 can extend from a front end that is proximate to a front side of the platform floor 162 back toward the rear side of the platform floor 162, thus extending parallel to the blade slot 164. The platform floor 162 can also define a pair of recesses 186 extending up into the bottom of the platform floor 162.
The platform 160 can also include a pair of rings 190 extending down from left and right ends of the platform floor 162. The rings 190 can be sized and positioned so that the springs of the spring device 150 extend around the rings 190. Thus, the spring positioners 130 of the foundation 112 and the rings 190 of the platform 160 can cooperate to help keep the springs of the spring device 150 seated in place between the platform 160 and the foundation 112. The spring device 150 can provide an upward biasing force on the platform 160 relative to the foundation 112, thereby biasing the platform 160 toward a position in which the platform is raised to hide the first blade 140 in a hiding position. However, the spring device 150 can allow the platform 160 to descend to an exposing position wherein the first blade 140 is exposed when enough downward force is applied to the platform 160, relative to the foundation 112.
The platform 160 can also include platform fingers 194, which can descend from opposite left and right ends of the platform 160. The platform fingers 194 can each include a protrusion 196 near the bottom terminus of the platform finger 194 that extends outward and away from a center of the platform 160. Each protrusion 196 can include a foundation engaging surface 198 that faces upwardly and extends horizontally out from a body of the platform finger 194 and a sloped surface that extends in and down from a terminus of the foundation engaging surface 198. The foundation engaging surface 198 of each platform finger 194 can abut a platform engaging surface 138 of the foundation 112 in the blade hiding position, which can oppose the force of the spring device 150 and inhibit a complete separation of the platform 160 from the foundation 112. However, the platform 160 can be allowed to move downward from the blade hiding position, with the platform fingers 194 sliding within the apertures 136 and the platform 160 sliding up and down within the wall 120 of the foundation 112.
The first housing 110 can also include a pill positioner 210, which can be mounted on the platform 160 and move up and down with the platform 160 but can move horizontally relative to the platform 160. Specifically, the pill positioner 210 can include a front face 212, which can be a generally rectangular wall that is sized to fit at least partially into the access cutout 126 of the foundation 112. The pill positioner 210 can also include a tab 214 extending forward from the front face 212 so that the tab 214 can be grasped as a handle for the pill positioner 210. Additionally, the pill positioner 210 can include a top plate 220, which can extend rearward from the front face 212 along the top surface of the platform floor 162. Moveable pill positioning walls 222 can be fixed to the rear end of the top plate 220, and can extend up from the top plate as well as extending rearward as they extend outward from a blade slot 224 that can extend front-to-rear along the top plate 220. The blade slot 224 can extend through the top plate 220 and between the moveable pill positioning walls 222. Also, the blade slot 224 can align with the blade slot 164 of the platform 160, allowing the first blade 140 to extend through the blade slot 224 and the blade slot 164 when the platform 160 is pushed down to expose the first blade 140. The curvature of the moveable pill positioning walls 222 and the fixed pill positioning walls 170 can be seen in
As the pill positioner 210 slides forward and rearward along the platform 160, the front face 212 of the platform can abut the front edge of the platform 160 to prevent the pill positioner 210 from sliding too far forward (or such forward movement may be stopped by the moveable pill positioning walls 222 abutting the fixed pill positioning walls 170 or a pill 230 positioned between the walls). Rearward movement of the pill positioner 210 can be inhibited when the moveable pill positioning walls 222 abut the top stops 176 of the platform 160.
The pill positioner 210 can also include a pair of fingers 240 that can extend rearward from left and right ends of the front face 212 along the bottom surface of the platform 160 (see
The tab 214 can be grasped to pull the pill positioner 210 forward to an extended position, which can allow a pill to be placed between the moveable pill positioning walls 222 and the fixed pill positioning walls 170. The fingertips 242 can abut the bottom stops 178 of the platform 160 while the moveable pill positioning walls 222 abut the top stops 176 to inhibit further extending movement of the pill positioner 210.

Inner surfaces of the left and right ends of the wall 264 can include protrusions 268 that can be sized and positioned to extend into the lid engagement recesses 134 of the foundation 112 when the second housing 260 is placed down over the first housing 110. In this closed position, a lower edge of the wall 264 of the second housing 260 can rest on the ledge 122 of the foundation 112. Also in this closed position, the second housing 260 and the first housing 110 can cooperate to define a pill container space 270, which can be a fully enclosed space with the first pill splitter 100, although in some embodiments the container space may not be fully enclosed. In an open position, the second housing 260 can be fully removed from the first housing, although in other embodiments a second housing may be connected to a first housing, such as with a hinge.
The wall 264 of the second housing 260 can define upwardly-extending cutouts 276 that can align with the access cutout 126 of the foundation 112 when the pill splitter is in the closed position, allowing for access for the pill positioner 210. The second housing 260 can also include a blade support 280, which can extend front-to-rear between front and rear portions of the wall 264. The blade support 280 can also extend down from a bottom of the ceiling 262. A second blade 290 can be seated in the blade support 280 and can extend downwardly therefrom and slope inwardly to a cutting edge 292 that can face downwardly. The second blade 290 can be positioned above the first blade 140 as the wall 264 of the second housing and the wall 120 of the first housing guide the second blade 290 downwardly toward the first blade 140. The first blade 140 and the second blade 290 can also be aligned in a plane, as can their cutting edges. As the second housing 260 slides down onto the first housing 110, the cutting edge 292 of the second blade 290 can remain aligned with and move toward the cutting edge 142 of the first blade 140.
B. First Pill Splitter Use
Use of the first pill splitter 100 will now be discussed. Referring now to
For splitting the pill 230, as illustrated in
Accordingly, the first pill splitter 100 can allow a user to split a pill by applying a downward force, rather than needing to squeeze the pill splitter. This can allow for easier pill splitting for many users. Additionally, allowing for this type of splitting with two blades cutting into the pill can make pill splitting even easier for a user, and can allow for a precise cut as the pill splits between the two blades. Accordingly, the first pill splitter 100 can provide substantial benefits, and additional features of the pill splitter can provide benefits alone, in combination with this overall downward-pushing two-blade feature, and/or in combination with other advantageous features discussed herein.
The first pill splitter 100 can also work as a pill container to hold pills in the pill container space 270, and the pill container space 270 can also contain parts of the pill during and after pill splitting.
In addition to the beneficial functional features of the first pill splitter 100, the first pill splitter 100 and the other pill splitters discussed herein provide aesthetically pleasing ornamental features, as can be seen in the accompanying figures.
C. First Pill Splitter Manufacturing and Materials
The parts of the pill splitter can be made of any materials that are sufficiently strong, hard, and durable for the functions and structure discussed herein. Also, different parts may be made with different materials that have different properties, although some parts may be made with the same materials. As an example, most of the parts of the first pill splitter 100 can be polymer parts that can be molded and/or formed in some other manner, such as additive (e.g., 3D printing) and/or subtractive (e.g., milling and/or drilling) manufacturing techniques. The first blade 140 and the second blade 290 may be the same as each other and may be formed of the same materials such as metal (e.g., steel) that is suitable for cutting blades. The springs may be made of spring metal, such as spring steel. Accordingly, the first blade 140 and the second blade 290 may each be made of materials that are stronger and harder than materials proximate to those blades, including materials of the blade supports of the first and second housings. Such strength and hardness values may be tested using standard techniques, such as tensile strength tests and Rockwell surface hardness tests.
In assembling the pill splitter, the first blade 140 and the second blade 290 may each be inserted into the corresponding blade support and may be held in place with a force fit and/or in some other way such as with an adhesive. Alternatively, the blades may be positioned in the molds when the second housing and the foundation are molded, so that the molding may assist in holding the blades in place. Additionally, the blades may include holes extending therethrough so that portions of the blade support can extend through the holes in the blades to secure the blades in place.
The pill positioner 210 can be slid onto the platform 160, which can include biasing the fingers 240 and/or the top plate 220 away from each other so that the fingertips 242 and the moveable pill positioning walls can slide past the bottom stops 178 and the top stops 176.
Additionally, the springs of the spring device 150 can be seated on the spring positioners of the foundation 112, and the platform 160 can be slid down within the wall 120 of the foundation 112. The sloped surfaces of the protrusion 196 of the platform fingers 194 can bias the platform fingers 194 inward as the platform 160 descends, until the protrusions reach the apertures 136, which allow the ends of the platform fingers 194 to spring outward with the protrusions being positioned below the platform engaging surfaces 138.
A. Second Pill Splitter Structure
A second pill splitter 400 is illustrated in
The first housing 410 can also include a wall 440 that extends up and down from a periphery of the floor portions 414 and the support ledges 417. The wall 440 can include a downwardly-extending access cutout 442 therein. The foundation 412 can also include a stationary pill positioning device 450, which can include a pair of fixed pill positioning walls 452 that extend forward from a central portion of the rear of the wall 440, centered over the first blade 430. From that position, the fixed pill positioning walls 452 can extend forward and out. Accordingly, a pill can be centered over the first blade 430 by pushing the pill rearward against the fixed pill positioning walls 452.
The first housing 410 can also include a platform 460, which can be moveable and can include a pair of mats 470, which can be elastically compressible, such as mats made of an elastic material, such as an elastomeric material. However, some examples may have a single mat with a blade access slot formed therein and aligned with the first blade. The mats 470 can be positioned on the support ledges 417, with the first blade 430 being positioned in a gap 472 between the mats 470. Accordingly, the mats 470 can move downward and upward adjacent to the first blade 430 without the first blade 430 interfering with movement of the mats 470. The mats 470 may be secured to the support ledges 417, such as with an adhesive material. Thus, a central portion of the mats 470 adjacent to a central portion of the first blade 430 can move down to expose the first blade 430, with the natural elastic properties of the mats 470 biasing the central portion back up to a flat position that hides the first blade 430. Accordingly, the mats 470 can act as both a spring device and a moving platform 460.
In some different examples elastic mats may be seated so that their bottom surfaces are fixed, while allowing the top surfaces to depress. Such movement can be considered movement of a pill-supporting platform, as with the other platform movements discussed herein.
The second pill splitter 400 can also include a second housing 480, which can include a wall 482 that can be oriented vertically and can continuously extend around a wall of the foundation 412. The second housing 480 can also include a blade support 483, which can include a pair of protrusions 484, with one protrusion 484 extending forward from a central upper portion of a rear side of the wall 482 and another protrusion 484 extending rearward from a central upper portion of a front side of the wall 482. Each of the protrusions 484 can define a blade support slot 486 that can open downwardly. Additionally, the blade support 483 can include a brace 488 that extends between upper portions of the protrusions 484. A second blade 490 can be seated in the blade support slots 486 of the protrusions 484, and a top of the second blade 490 can extend along a bottom surface of the brace 488. The second blade 490 can extend down to a cutting edge 492. The second blade 490 and the first blade 430 can each be secured in place in one or more ways, such as the ways of securing blades described above with respect to the first pill splitter. With the second housing 480 positioned on the first housing 410, the second blade 490 can be positioned above and coplanar with the first blade 430.
Rather than having a ceiling, the second housing 480 can be open on its top side. This has an advantage of allowing a user to have visual and/or tactile access to a pill container space 494 while the second housing 480 is positioned on the first housing 410, although the pill container space 494 is not fully enclosed. Alternatively, the second housing may include a ceiling to fully enclose the pill container space. Also, one or more parts of the pill splitters in one or more of the embodiments discussed herein may be clear to allow a user to see the interior of the pill container space, even if the pill container space is fully enclosed.
B. Second Pill Splitter Use
Use of the second pill splitter 400 will now be discussed with reference to
For splitting the pill 496, as illustrated in
Accordingly, as with the first pill splitter 100, the second pill splitter 400 can allow a user to split a pill by applying a downward force, rather than needing to squeeze the pill splitter. This can allow for easier pill splitting for many users. Additionally, allowing for this type of splitting with two blades cutting into the pill can make pill splitting even easier for a user, and can allow for a precise cut as the pill splits between the two blades. Accordingly, the second pill splitter 400 can provide substantial benefits, and additional features of the pill splitter can provide benefits alone, in combination with this overall downward-pushing two-blade feature, and/or in combination with other advantageous features discussed herein.
The second pill splitter 400 can also work as a pill container to hold pills in the pill container space 494, and the pill container space 494 can also contain parts of the pill during pill splitting, although the pill container space 494 may not be fully enclosed.
C. Second Pill Splitter Manufacturing and Materials
The second pill splitter 400 can be made with materials and manufacturing techniques like those discussed above for the first pill splitter 100. Additionally, the mats 470 may be made of materials with elastomeric properties that allow the mats to be depressed as illustrated in
A. Third Pill Splitter Structure
Referring now to
The first housing 510 can further include a platform 540 that is moveable relative to the foundation 512, with a platform floor 542 of the platform 540 extending horizontally within the wall 514 of the foundation 512. The platform 540 can be shaped so that a periphery of the platform 540 matches and is positioned inside an inner face of the wall 514, with a gap being defined between the wall 514 and the platform 540. The platform 540 can define a blade access slot 544 therein, which can extend front-to-rear above the cutting edge 532 of the first blade 530, allowing an upper portion of the first blade 530 to be exposed through the blade access slot 544 when the platform floor 542 descends below the cutting edge 532 of the first blade 530.
The first housing 510 can further include a spring device 550, which can include a set of springs 552, such as the set of four springs illustrated in
The platform 540 may further include a stationary pill positioning device 560, which can include a pair of fixed pill positioning walls 562 that extend forward and out from a central portion of the rear of the platform 540, on each side of the blade access slot 544. Accordingly, a pill can be centered over the first blade 530 by pushing the pill rearward against the fixed pill positioning walls 562.
The third pill splitter 500 can also include a second housing 580 that is like the second housing 480 of the second pill splitter 400. The second housing 580 can include a wall 582 that can be oriented vertically and continuously extend around the wall of the foundation 512. The second housing 580 can also include a blade support 583, which can include a pair of protrusions 584, with one protrusion 584 extending forward from a central upper portion of a rear side of the wall 582 and another protrusion 584 extending rearward from a central upper portion of a front side of the wall 582. Each of the protrusions 584 can define a blade support slot that opens downwardly. Additionally, the blade support 583 can include a brace 588 that extends between upper portions of the protrusions 584. A second blade 590 can be seated in the blade support slots of the protrusions 584, and a top of the second blade 590 can extend along a bottom surface of the brace 588. The second blade 590 and the first blade 530 can each be secured in place in one or more ways, such as the ways of securing blades described above with respect to the first pill splitter 100. With the second housing 580 positioned on the first housing 510, the second blade 590 can be positioned above and coplanar with the first blade 530, as illustrated in
B. Use of the Third Pill Splitter
Use of the third pill splitter 500 will now be discussed with reference to
For splitting the pill 496, as illustrated in
Accordingly, as with the first pill splitter 100, the third pill splitter 500 can allow a user to split a pill by applying a downward force, rather than needing to squeeze the pill splitter. This can allow for easier pill splitting for many users. Additionally, allowing for this type of splitting with two blades cutting into the pill can make pill splitting even easier for a user, and can allow for a precise cut as the pill splits between the two blades. Accordingly, the second pill splitter 400 can provide substantial benefits, and additional features of the pill splitter can provide benefits alone, in combination with this overall downward-pushing two-blade feature, and/or in combination with other advantageous features discussed herein.
The third pill splitter 500 can also work as a pill container to hold pills in a pill container space 594 (above the platform 540 and in the space defined by the wall 514 of the foundation 512), and the pill container space 594 can also contain parts of the pill during pill splitting, although the pill container space 594 may not be fully enclosed.
C. Third Pill Splitter Manufacturing and Materials
The third pill splitter 500 can be made with materials and manufacturing techniques like those discussed above for the first pill splitter 100 and the second pill splitter 400.
A. Fourth Pill Splitter Structure
Referring now to
The foundation 612 can further include a blade support 626, which can be centrally located between left and right ends of the foundation floor 614 and can extend front-to-rear as well as above and below the foundation floor 614. The blade support 626 can define a slot within which a first blade 630 can be seated. The first blade 630 can extend up to a cutting edge 632, like the first blades discussed above.
The first housing 610 can further include a spring device 634. The spring device 634 can include a pair of cantilevered springs 636 that can each be secured to the blade support 626 of the foundation 612 and can extend up and out (up and left or right in the illustrated example) from the blade support 626. Thus, the cantilevered springs 636 can each extend above the foundation floor 614 of the foundation 612.
The first housing 610 can further include a platform 640, which can include a platform floor 642. The platform floor 642 can be generally shaped similarly to the foundation floor 614 of the foundation 612. However, the platform floor 642 can be smaller than the foundation floor 614 of the foundation 612. The platform floor 642 of the platform 640 can include a raised central portion forming a ridge 646 extending from front to rear. The ridge 646 can define a slot 648 therein that extends in a front-to-rear direction. Additionally, the ridge 646 can include support ledges 650 extending into the slot 648 from opposite left and right sides of the slot 648. An upper surface of each support ledge 650 can be positioned below an upper surface of the ridge 646 adjacent to each support ledge 650. The support ledges 650 can extend forward from a rear side of the platform floor 642, but the support ledges 650 can terminate before reaching a front side of the platform floor 642.
The platform 640 can also include a platform wall 654, which can extend up from a periphery of the platform floor 642. The platform wall 654 can define a pair of cutouts 656 that extend downwardly and are centrally located between left and right ends of the platform wall 654, with one cutout 656 on a front portion of the platform wall 654 and one cutout 656 on a rear portion of the platform wall 654.
The platform 640 can also include platform fingers 660, with a pair of the platform fingers 660 descending from a front end of the ridge 646 of the platform floor 642 and a pair of the platform fingers 660 descending from a rear end of the ridge 646. The platform fingers 660 can each include a protrusion 662 near the bottom terminus of the platform finger 660 that extends outward and away from a center of the platform 640. Each protrusion 662 can include a foundation engaging surface 664 that faces upwardly and extends horizontally out from a body of the platform finger 660 and a sloped surface that extends in and down from an outer terminus of the foundation engaging surface 664. The foundation engaging surface 664 of each platform finger 660 can abut a platform engaging surface 624 of the foundation 612 in the blade hiding position, which can oppose the force of the spring device 634 (wherein each of the cantilevered springs 636 can bias the platform 640 upward to a blade hiding position) and inhibit a complete separation of the platform 640 from the foundation 612. However, the platform 640 can be allowed to move downward from the blade hiding position, with the platform fingers 660 sliding within the access recesses 622 and the platform 640 sliding up and down within the wall 618 of the foundation 612.
The platform 640 can further include fixed pill positioning walls 670, with one fixed pill positioning wall 670 extending up from the ridge 646 on each side of the slot 648. The fixed pill positioning walls 670 can generally extend rearward toward a rear of the ridge 646 as they extend out to the sides of the slot 648. Accordingly, as a pill is pushed forward against the fixed pill positioning walls 670, the pill can tend to slide toward the center, so that the pill is centered over the slot 648. Rearward-facing surfaces 672 of the fixed pill positioning walls 670 can be generally convex, with each rearward-facing surface 672 including a first section that angles forward and out from the slot 648 and a second section that extends to the left or right away from the slot 648 (such as where the second section can extend perpendicular to the slot 648).
The first housing can further include a pill positioner 680, which can act together with the fixed pill positioning walls as a pill positioning device 682. The pill positioner 680 can be configured to move up and down with the platform 640 upon which it is mounted but can move horizontally relative to the platform 640. The pill positioner 680 can include a tab 684 that can curve upwardly as it extends forward to be grasped as a handle for the pill positioner 680. Additionally, the pill positioner 680 can include a plate 688, which can extend rearward from the tab 684 within the slot 648 and along the top surfaces of the support ledges 650. Moveable pill positioning walls 692 can be fixed to the rear end of the plate 688 and can extend up from the plate as well as extending forward as they extend outward from a blade slot 694 that can extend front-to-rear along the plate 688. The blade slot 694 can extend through the plate 688 and between the moveable pill positioning walls 692. Also, the blade slot 694 can align with the slot 648 of the platform 640, allowing the first blade 630 to extend through the blade slot 694 and the slot 648 when the platform 640 is pushed down to expose the first blade 630. The curvature of the moveable pill positioning walls 692 and the fixed pill positioning walls 670 can be seen in
The pill positioner 680 can further include a pair of engaging fingers 696 rearward of the moveable pill positioning walls 692, with each of the engaging fingers 696 extending down and then outward to engage downwardly-facing surfaces of the support ledges 650, helping to inhibit vertical movement of the pill positioner 680 relative to the platform 640. The fixed pill positioning walls 670 and the pill positioner 210 can cooperate to center a pill over the blade slot 694, the slot 648, and the first blade 630. Thus, the fixed pill positioning walls 670 and the pill positioner 680 together form the pill positioning device 682, which can be a mechanism with the pill positioner 680 moving relative to the fixed pill positioning walls 670 to initially position and to hold pills of different shapes and sizes in a centered position.
Referring now to
In a closed position, as illustrated in
The wall 714 of the second housing 710 can define cutouts 726 that extend upwardly and can align with an access cutout in the front section of the platform wall 654 through which the plate 688 of the pill positioner 680 can extend. Thus, the plate 688 and/or the tab 684 of the pill positioner 680 can extend through one of the cutouts 726 in the second housing 710 when the fourth pill splitter 600 is in the closed position.
The second housing 710 can also include blade supports 730, which can extend forward from the rear portion of the wall 714 and rearward from the front portion of the wall 714. The blade supports 730 can define slots 732 that open downwardly. A second blade 740 can be seated in the slots 732 of the blade supports 730 and can extend down therefrom and narrow to a cutting edge 742 that can face downwardly. The second blade 740 can be positioned above the first blade 630 with the first blade 630 and the second blade 740 being aligned in a plane. As the second housing 710 slides down onto the first housing 610, the cutting edges of the second blade 740 and the first blade 630 can remain aligned and move toward each other.
B. Use of Fourth Pill Splitter
The fourth pill splitter 600 can be used similarly to the other pill splitter examples discussed above, with similar parts (and similarly-named parts) performing similar functions during use.
C. Fourth Pill Splitter Manufacturing and Materials
The fourth pill splitter 600 can be made with materials and manufacturing techniques like those discussed above for the first pill splitter 100.
In assembling the fourth pill splitter 600, the blades can be assembled and secured similarly to the techniques discussed above with respect to the blades of the other pill splitter examples. The ceiling 712 of the second housing 710 can be snapped into place in the wall 714 of the second housing 710.
The tab 684 of the pill positioner 680 can inserted downwardly through the slot 648 in the ridge 646 of the platform 640, forward of the support ledges 650. The rear of the pill positioner 680 can then be pressed downwardly to allow the engaging fingers 696 to engage the downwardly-facing surfaces of the support ledges 650. Thus, the plate 688 of the pill positioner 680 can be positioned within the slot 648 and can slide forward and rearward along the slot 648.
The platform 640 can then be pressed into the foundation 612 so that the platform fingers 660 can extend into the access recesses 622 of the foundation 612. The second housing 710 can then be slid downward onto the first housing 610 to form the closed position for the fourth pill splitter 600.
While embodiments are discussed above, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. For example, some of the platforms are illustrated as being flat, but the platform may be different shapes, such as curved shapes, so long as the platform is configured to support a pill as discussed herein. As another example, instead of the platforms including fingers and protrusions to extend into apertures in the foundation to secure the platform to the foundation but still allow movement of the platform relative to the foundation, this could be reversed, with the foundation including fingers and protrusions to extend into apertures in the platform to help secure the platform to the foundation but to allow movement of the platform relative to the foundation.
