Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for the claims and/or as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0067] In reference to the drawings, FIGS. 1 and 2 illustrate the first embodiment 20 of the instant invention. FIG. 1 illustrates embodiment 20 already assembled while FIG. 2 shows individual parts of first embodiment 20.

[0068] Embodiment 20 comprises an elongated ergonomic handle 21, scraper 22, head 23 and head cap 24. External surface of the head 23 comprises an operational lining 25 used in the maintenance of nails. The phrase operational lining as recited in this application is defined as a material normally used in the maintenance of nails such as those used in the nail polish removal or nail buffing. Embodiment 20 also comprises a system that enables the holding or release of the head 23 at the will of the User, without the need to touch the head 23. The ergonomic design of the handle 21 provides a suitable shape where the User may place and accommodate its hand and fingers, thus allowing the relaxation of the hand muscles even after hours of using the tool.

[0069] As shown in FIGS. 1 and 2, elongated ergonomic handle 21 comprises a cylindrical section 26 and a rectangular section 27. Cylindrical section 26 starts at the first end 28 of the handle 21 and constantly increases in diameter to further decrease said diameter up to position 29, wherein there is a transition in geometry from a cylindrical shape to a rectangular shape, thus providing second rectangular section 27, which concludes in second end 30 of the handle 21. First end 28 comprises a cylindrical internal cavity 31, while second end 30 comprises an internal rectangular cavity 32. Furthermore, first embodiment 20 also comprises a slider button 33, located at the aperture 33a on the topside 34 of the rectangular section 27. Elongated ergonomic handle 20 may be made of any suitable rigid, durable material such as molded plastic, resin, metal, or plastic; more preferably, resin or plastic.

[0070] Scraper 22 is a stick made of any solid and firm material such as, felt, wood, firm foam, plastic or other suitable material. It comprises a cylindrical body 35 with a first pointy or tip end 36 and a second diagonal end 37. Scraper 22 may be inserted in a nonpermanent manner into the cylindrical internal cavity 31 located at the first end 28 of handle 21.

[0071] Head 23 is connected in a non-permanent manner to second end 30 of handle 21. It is disposable or reusable and may be ejected from handle 21 by slider button 33, as explained below. As illustrated in FIG. 3, head 23 comprises a single unit body with an external geometrical shape having a tridimensional rectangular section 38 with curved or concave lateral sides 39a, 39b, 39c, and 39d that are extended continuously into a four-sided pyramidal shape top section 40.

[0072] Embodiment 20 also comprises at the curved or concave sides 39a, 39b, 39c, and 39d, as well as the corresponding sides of top section 40, a lining 41 of a suitable material capable to absorb and retain fluids, such as felt, polypropylene, cotton and sponge; more preferably felt or polypropylene. Said lining of absorbent material is adhered to said sides by means of any suitable covering methods known in the art. For instance, the absorbent material may be molded in a single unit or sheath layer 42 that simulates the shape of the head 23 and further adhered to the head 23. Such single unit or sheath layer 42, illustrated in FIG. 4, may be suitably made by heat molding process, in a cap-like shape that fits to cover the upper surface of all the sides 39a, 39b, 39c, and 39d of rectangular section 38 and corresponding sides of top section 40. Subsequently, said sheath layer 42 is adhered to the head 23 using a suitable gluing, cementing or bonding mean, known in the art, that is resistant to acetone and the like solvents. Such mean may include adhesives, such as hot-melt adhesives, glues, epoxies, double sided adhesive and thermal bonding. In a preferred embodiment, a bonding medium, such as an adhesive resistant to acetone and the like solvents, is employed to adhere and secure the sheath layer 42 of the selected absorbent material over the surface of head 23. In an alternative method, said lining may be adhered to the lateral sides 39a, 39b, 39c, and 39d of the head 23 by adhering a rectangular strip 43 of the selected absorbent material, illustrated in FIG. 5, around the said lateral sides, thus lining rectangular section 38. Subsequently, top section 40 is covered or lined by adhering on it a single piece 44 of the absorbent material, as the one illustrated in FIG. 6.

[0073] FIG. 7 represents a perspective view of head 23 disconnected from handle 21. As illustrated, head 23 comprises an internal cavity 45 having a rectangular shape.

It also comprises a second wedge 64 located at the second end 63 of the second head locking snap 58.

[0076] As illustrated in FIG. 8, first embodiment 20 also comprises an elongated protruding extension 65 located at substantially or near at substantially the center of bottom side 49 of internal cavity 45 of head 23. It also comprises a protruding cylindrical section 66 that extends from the center or near the center of the internal distal flat wall 50.

[0077] FIG. 10 illustrates the head cap 67 that may be made of plastic and simulates the external shape of head 23. This cap is intended to cover head 23 in order to protect it one it is not being used.

[0078] Head 23 is not permanently attached to handle 21 and it may be ejected from said elongated body one the User slides button 33 backwardly. The ejection of head 23 is possible due to a system that allows the hold and release of head 23 on or from handle 21, respectively. As illustrated in FIG. 11, said system comprises first cap 68, first compression spring 69, actuator 70, cartridge 71, cover 72, second compression spring 73, plunger 74, second cap 75 and slider button 33.

[0079] Regarding first cap 68, it comprises a main square body 76 with a front surface 77 and a rear surface 78; it also comprises a first extension 79, having a first end 80 connected to the rear surface 78 on square body 76 and a second end 81.

Said second extension 85 also comprises a second wedge 86, located at the lateral side of the second end 85. First extension 79 and second extension 83 are located in a parallel position, in other words, they are aligned in reference to one another while first and second wedges 82 and 86 are positioned in an outwardly position with reference to the first and second extensions, 79 and 83.

[0080] First compression spring 69 and second compression spring 73 are made of any material with sufficient strength to withstand repeated use, for instance plastic, steel or stainless steel, but preferably stainless steel.

[0081] As illustrated in FIG. 12, actuator 70 comprises a main rectangular body 87 having a proximal end 88 and a distal end 89; it also has a first section 90 and a second section 91. First section 90 comprises internal cavity 92, which has a round entrance 93, located at the front side 94 of the first section 90. Connected to said first section 90, second section 91 comprises an internal cavity 95 having an opening 96 located on the top side 97 of second section 91. Said opening 96, has a top section 98 and a bottom section 99, wherein diameter of the bottom section 99 is broader than the top section 98. With exception of the internal cavity 95, the remaining interior of the second section 91 of the rectangular body 87 is solid.

[0082] As shown in FIG. 12, and located at the distal end 89, actuator 70 also comprises a first extension 100, having a first end 101 and a second end 102. Said second end 102 comprises a first wedge section 103 connected to the lateral side of said second end 102. Similarly, and located at the distal end 89 of actuator 70 and in a parallel position with reference to the first extension 100, said actuator 70 also comprises a second extension 104 having a first end 105 and a second end 106. Located laterally at second end 106, said second extension 104 comprises a second wedge 107.

[0083] As shown in FIG. 13 in an expanded view, cartridge 71 comprises a rectangular hollow body 108 having topside 109, a right side 110, a left side 111, a bottom side 112, a proximal end 113 and a distal end 114.

[0084] On topside 109, near the proximal end 113, it comprises a rectangular depression 115, which has inside a rectangular aperture 116 that is open to the internal section 117 of the cartridge 71. On the right side 110, there is a first aperture 118; a second aperture 119, having a broader section 120 and a narrower section 121; and a third aperture 122. Similarly, in the left side 111 there are a first aperture 123; a second aperture 124, having a broader section 125 and a narrower section 126; and a third aperture 127. The first aperture 118 on the right side 110 is aligned or is parallel to the first aperture 123 on the left side 111, being both of said first apertures, 118 and 123, located near the proximal end 113 of cartridge 71 and, simultaneously, said first apertures, 118 and 123, are aligned to aperture 116 on topside 109. Second aperture 119 on right side 110 is aligned to the second aperture 124 on the left side 111.

[0085] Similarly, the third aperture 122 on the right side 110 is aligned to the third aperture 127 on the left side 111 and are located near the distal end 114 of cartridge 71. Cartridge 71 also comprises an inner wall 128 comprising a round opening 129. Said inner wall 128 is located inside the cartridge 71, in the internal section 130 that is between the second apertures, 119, 124, and third apertures 122, 127. On the bottom side 112, cartridge 71, near the distal end 114, comprises rail 131.

[0086] The system also comprises a plunger 74, which comprises a cylindrical body 132 having a first end 133 and a second end 134. Plunger 74 also comprises a rectangular section 135, which have a front surface 136 and a rear surface 137, as illustrated on FIG. 14. The cylindrical body 132 is attached to the front surface 136 of rectangular section 135. The rear surface 137 has a round depression 138 at its center.

[0087] Furthermore, the system comprises a second cap 75 similar to the first cap 68: it comprises a main square body 139 with a front surface 140 and a rear surface 141, having a circular opening 142 across said front and rear surfaces, 140, 141, and having a carved out section 143 of bottom side 144 of said body 139; it also comprises a first extension 145, having a first end 146 connected to the rear surface 141 on square body 139 and a second end 147. Said second end 147 of first extension 145 also comprises a first wedge section 148 connected to the lateral side of said second end 147. Square body 139 also comprises a second extension 149, having a first end 150 connected to the rear surface 141 on square body 139 and a second end 151. Said second extension 149 also comprises a second wedge 152, located at the lateral side of the second end 151. First extension 145 and second extension 149 are located in a parallel position, in other words, they are aligned in reference to one another while first and second wedges, 148 and 152, are positioned in an outwardly position with reference to the first and second extensions, 145 and 149.

[0088] The system, capable of hold and release head 23 on or from the handle 21 respectively, also requires the slider button 33, said button comprises: a main body 153 having a front surface 154 and a rear surface 155; a first elongated extension 156, having a first end 157 and a second end 158; and a second elongated extension 159, having a first end 160 and a second end 161. First and second elongated extensions, 156 and 159, are connected to the rear surface 155 in a parallel position in reference to one another. Slider button 33 also comprises first wedge 162, which is positioned laterally in the second end 158 of the first extension 156, and second wedge 163, positioned laterally on second end 161 of the second extension 159. Both, first and second wedges, 162 and 163, are positioned outwardly from the first and second extensions 156 and 159.

[0089] As suggested in FIG. 15, first spring 69 is inserted and enclosed between the aligned first and second extension, 79 and 83, of first cap 68 and the internal cavity 92 of the first section 90 of actuator 70 via round entrance 93. First and second extensions, 100 and 104, of actuator 70 are inserted into the internal section 117 of the cartridge 71 through its proximal end 113 until actuator 70 is fully introduced inside internal section 117. Consequently, first wedge 103 and second wedge 107 on first and second extension 100 and 104 of actuator 70 are positioned on the narrower sections 121 and 126 of the second apertures 119 and 124 from the interior surface of the internal cavity 117 of the cartridge 71, located on the right and left side, 110 and 111, of the cartridge 71. In this manner, first wedge 82 and second wedge 86 of first extension 79 and second extension 83 of first cap 68 are inserted in third aperture 122 and third aperture 127 on right and left side, 110 and 111, of cartridge 71, restricting first spring 69 to the space between the first cap 68 and the internal section 92 of actuator 70.

[0090] As a consequence, aperture 96 on top side 97 of actuator 70 is aligned with aperture 116 on the top side 109 of cartridge 71; first wedge 103 of first extension 100 of actuator 70 is positioned in second aperture 119 on the right side 110 of cartridge 71; and second wedge 107 of second extension 104 of actuator 70 is positioned in second aperture 124 on the left side 111 of cartridge 71. Afterwards, cover 72 is placed on rectangular depression 115 on topside 109 of cartridge 71.

[0091] Furthermore, once the cartridge 71 has been assembled with the first cap 68, the first spring 69, actuator 70 and cover 72, as discussed previously, it is inserted at the rectangular section 27 of handle 21. Then, slider button 33 is inserted into aperture 33a on topside 34 of handle 21, thus passing through aperture 116 of the cartridge 71 and through the aperture 96 on the actuator 70 since both apertures 116 and 96 are already aligned. In this manner, first wedge 162 on first extension 156 of the slider button 33 and second wedge 163 of the second extension 159 of the slider button 33 are inserted and secured at broader section 99 on aperture 96 of actuator 87.

[0092] On the other hand, second spring 73 is inserted into the cylindrical section 132 of plunger 74; rectangular section 135 of the plunger 74 is inserted between the first extension 145 and second extension 149 of second cap 75. Cylindrical section 132 of plunger 74, having second spring 73 already inserted into it is then introduced into the internal section 117 of cartridge 71. In this manner, second spring 73 is kept captive between internal wall 130 of cartridge 71 and front surface 136 of rectangular section 135 of plunger 74, since the first wedge 148 on the first extension 145 of the second cap 139 is inserted and secured within the third aperture 122 on the right side 110 of cartridge 71 and the second wedge 152 of the second extension 149 of the second cap 75 is inserted and secured into third aperture 127 on the left side 111 of cartridge 71.

[0093] Once the cartridge 71 containing the different components of the hold/release system already set up is inserted into the rectangular distal section 27 of elongated ergonomic handle 21, the distal section 114 of cartridge 71 is then inserted into the internal rectangular cavity 45 of head 23 by matching rail 131 on the bottom side 112 of cartridge 71 with the protruding cylindrical section 66 on the bottom side 49 of rectangular internal cavity 45 on the interior of head 23. By inserting distal section 114 of the cartridge 71 on the interior rectangular cavity 45 inside head 23, the protruding cylindrical section 66 that extends from the center or near the center of the internal distal flat wall 50 enters through the round aperture 142 of second cap 75, matching the round depression 138 on the rear surface 137 of the rectangular section 135 of plunger 74.

[0094] In this manner, once the second end 66a of protruding cylindrical section 66 is accommodated inside round depression 138 on the rear surface 137 of plunger 74, it pushes and contracts the second spring 73 in between the front surface 136 of plunger 74 and the internal wall 130 on cartridge 71 while the head 23 is connected to the handle 21. As a consequence, first wedge 57 on the first head locking snap 51 is moved along the external surface of the right side 110 of the cartridge 71 until it is inserted and secured on the broader section 120 of the second aperture 119 of the cartridge 71. Simultaneously, the second wedge 64 of the second head locking snap 58 moves along the external surface of the left side 111 of the cartridge 71 until it is inserted and secured on the broader section 125 of the second aperture 124 of the cartridge 71.

[0095] The release of the head 23 is achieved once the button 33 is moved backwards and released, since extensions 156 and 159 on button 33 pull the actuator 70 backwards due to the fact that button's wedges, 162 and 163, are secured into the internal cavity 95 of the actuator 70. Such movement presses and compresses the first spring 69. Also, actuator's first and second wedges, 103 and 107, are repositioned from the narrower sections 121 and 126 to the broader sections 120 and 125 of the second cartridge apertures 119 and 124. Such reposition, simultaneously, results in the release or disconnection of wedges 57 and 64 of first and second head locking snaps, 51 and 58, since they are pushed outwardly from the broader sections 120 and 125 on second apertures 119 and 124. Thus, second spring 73 is free to release its potential energy into kinetic energy. In other words, second spring 73 is free to return to its relaxed-non-compressed -position and said kinetic energy moves the head 23 out of the handle 21. It should be noted that the first spring 69, once the slider button 33 is set fee, returns to the decompressed position, liberating kinetic energy that pushes the actuator 70 back to its initial position, re-positioning actuator's wedges 103 and 107 to the narrower sections, of the second apertures 119 and 124 on the right and left sides, 110 and 111, of cartridge 71.
