## Background
BACKGROUND
1. Technical Field
The present disclosure relates to an apparatus for the reclamation of liquids and, more particularly, relates to a system and apparatus for the collection and transportation of liquids such as engine oil and other similar fluids.
2. Background of the Related Art
In order to ensure the long life of an automobile, it is of critical importance that the engine oil be changed regularly. Typically, the automobile manufacturer recommends changing the oil every 3,000 to 5,000 miles. Many owners utilize various service centers and pay mechanics to change the oil for them. However, in an effort to conserve time and money many automobile owners change their own oil.
There are significant drawbacks, however, to changing your own oil. Most importantly, there is no convenient way of disposing the waste oil. Moreover, once the waste oil has been contained, it must be transported to a recycling center in order to comply with environmental laws. For the average automobile owner, this is no easy task. Dealing with engine oil can be very messy. Most automobile owners do not have the proper containers for the storage and subsequent transport of the waste oil. Thus, there remains a need for a more environmentally and user friendly automobile oil waste receptacle.

DETAIL DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
The liquid reclamation system and apparatus of the present disclosure provides the vehicle owner with a viable option when changing the oil in his/her car. Within the empty container of the apparatus, there may be a receptacle of new oil. This receptacle is removed from the container and the used oil may be drained into the container. Once the used oil is drained from the automobile and into the container, the new oil within the receptacle is emptied into the car. Then, the empty receptacle may be placed inside of the container with the used oil and the apparatus is sealed. The container may be configured to include a recessed bottom allowing for one container to be stacked on top of another. Furthermore, the containers may contain connective slots along the side, so that one container may be secured to an adjacent container. This horizontal and vertical connectivity facilitates storage and transport of a large number of apparatii 100, e.g., on a grate.
Referring now to the drawings, in which like reference numerals identify identical or substantially similar parts throughout the several views, FIGS. 1-3 illustrate the oil reclamation apparatus 100 of the present disclosure. Oil reclamation apparatus 100 includes container 102 dimensioned to receive and transport a liquid, e.g., oil. Container 102 has recessed bottom 104 which permits stacking of a plurality of apparatii 100 as will be discussed. Container 102 may define any shape in cross-section including circular, elliptical or polygonal. In one preferred embodiment, container 102 defines an octagonal shape having a plurality of interconnecting sides 106a-h. Other dimensions are also envisioned. Container 102 may be constructed of a variety of different materials including but not limited to polymeric and metallic materials.
Each container 102 may house portable receptacle 108 which is configured to fit within container 102 and is dimensioned to hold a liquid. Receptacle 108 includes a dispenser 110 to ease fluid transfer. Receptacle 108 may be any device capable of storing and dispensing fluid. In one embodiment, receptacle 108 is a polymeric bag filled with fluid oil “o” (see FIG. 1). Preferably, receptacle 108 is capable of accommodating a volume of liquid, e.g., five or six quarts, sufficient to perform an oil change on a vehicle. Other containers, cans, boxes, etc. are also envisioned. Dispenser 110 may be a spout or the like adapted for dispensing of oil. Dispenser 110 could be funnel or cone-shaped defining an internal lumen to permit the oil to be dispensed. Dispenser 110 may incorporate a one way valve. Other spouts, caps, nozzles etc. are also envisioned.
Container 102 may further include attachment rails 112 on at least two sides of the container 102 and attachment grooves 114 on another two sides. Attachment rails 112 of one container 102 are dimensioned to be received within attachment grooves 114 of an adjacent container 102 to facilitate storage and/or transport of a number of apparatii 100 in side by side relation. FIG. 4 illustrates several apparatii 100 stored in side by side relation with attachment rails 112 of one apparatii 100 being received within attachment grooves 114 of a second adjacent apparatii 100. Attachment rails 112 and grooves 114 may have a variety of configurations. In one preferred embodiment, the cross-sectional dimension of attachments rail 110 is generally t-shaped for reception within a correspondingly dimensioned t-shaped groove 112. Other shapes are also envisioned.
Container 102 may further include cover 116. Cover 116 may be detachably secured about rim 118 of container 102 by any means including threaded means, bayonet coupling, interference fit, etc. Cover 116 and rim 118 are dimensioned to be accommodated within recessed portion 104 of an adjacent stacked container 102 so as to interlock via a friction or interference fit with the recessed bottom 104 of container 102 thereby facilitating stacking of a large number of apparatii 100. FIG. 5 illustrates a stacked relation of two apparatii 100.
The side by side connectability of adjacent apparatii 100 as provided by attachment rails and grooves 110,112 and the stacking capability as provided by the reception of cover 114 and rim 116 within recess 104 substantially improves storage and transport of a large number of apparatii 100. Moreover, the side by side and vertical connecting features permits for a large number of apparatii to be stored and/or transported on, e.g., a grid. The grid may be lifted in unison by a forklift or other machine and loaded onto a transport vehicle as a single unit.
The operation of the liquid reclamation apparatus 100 of the present disclosure will now be discussed in the context of automobile engine oil replacement. Cover 116 is removed from container 102 and portable receptacle 106 is removed. Container 102 is placed underneath the automobile and the waste oil is drained into container 102. Portable receptacle 106 containing a fresh supply of oil is dispensed through dispenser 110 into the automobile, replacing the oil which was just drained. Portable receptacle 106, once emptied, may then be placed inside of container 102 with the waste oil. Cover 116 may then be secured to container 102 locking the waste oil and used portable receptacle 106 therein. Once secured, container 102 may be transported to a recycling facility for proper disposal.
Referring now to FIGS. 6-8, another embodiment of the present disclosure will be discussed. Liquid reclamation apparatus 200 includes container 202. Container 202 is preferably fabricated from a flexible membrane such as polypropylene, polyethylene, etc. . . . which permits the container 202 to expand from the collapsed transit condition shown in FIGS. 6-7 to the expanded in use condition shown in FIG. 8. In one preferred embodiment, container 202 defines medial hinge line 204 about which the membrane portions 206 adjacent and intersecting the hinge line 204 pivot to assume the expanded condition of FIG. 8. Preferably, the thickness of membrane portions 206 of container 202 increases or is greatest adjacent hinge line 204 to ensure that the container 202 remains in the expanded in use condition once it is deployed. It is also envisioned that the membrane may incorporate reinforcing structure such as strips of rigid polymeric material adjacent hinge line 204 to increase stability upon expansion of container 102. One skilled in the art may readily determine the dimensioning and material selection required to accomplish this objective.
Container 202 further includes upper and lower housing components 208, 210 disposed within the internal chamber of container 202. Upper and lower housing components 208, 210 may be fabricated from a polymeric material or the like and are preferably embedded, integrally formed or attached to container 202 by conventional means. Upper housing component 208 incorporates cap or cover 212 which is releasably mounted to the housing component 208. In one preferred embodiment, cap 212 and upper housing component 208 incorporate cooperating threads 214, 216 to establish the releasable attachment of the cap 212 to the housing component 208. Other connection arrangements are also envisioned including bayonet coupling, interference fit, etc. Cap 212 incorporates handle 218 which facilitates expansion of container 202 to the expanded condition by providing a means upon which the operator may grasp and expand the container 202. Handle 218 is preferably recessed within cap 312 so as to not extend beyond the outer boundary of container 202. It is envisioned that lower housing component 210 may incorporate a handle. Cap 212 further incorporates check valve 220 in fluid communication with the internal chamber of container 202. Check valve 220 permits the inflow of air into the container 202 so as to maintain the expanded condition of the container 202 while preventing the exit of air from the container 202. Check valve 220 may also be adapted to prevent the flow of oil from container 202 subsequent to performing the oil change.
Preferably, container 202 is shipped in the compressed condition of FIGS. 6-7 prior to use. As appreciated, multiple apparatii 200 may be packaged in its compressed condition into a single package, e.g., in stacked relation. Container 202 may or may not be provided with oil receptacle having a supply of oil sufficient to perform an oil change. In use by an operator, container 202 is expanded from the transit condition of FIGS. 6-7 to the expanded condition of FIG. 8. Cap 212 is removed and the used oil is drained from the vehicle into container 202. Upon completion, cap 212 is placed back onto container 202 and secured thereon through the threaded means.
Referring now to FIGS. 9-11, another embodiment of the present disclosure will now be discussed. Liquid reclamation apparatus 300 includes container 302 and dispenser cover 304 releasably mounted to the container. Portable flexible receptacle 306 is attached to dispenser cover 304 and is disposed within container 302. Receptacle 306 is dimensioned to hold oil. Dispenser cover 304 defines spout 308 to permit dispensing of the oil contained within receptacle 306. Dispenser cover 304 may be detachably mounted to container 302 via a threaded connection 310. Apparatus 300 further includes cap 312 which is releasably mounted to spout 308 of dispenser cover 304 by conventional means.
In use, apparatus 300 may be purchased full of oil or it may be empty. If full, dispenser cover 304 is unscrewed and the dispenser cover with attached portable receptacle 306 are removed from container 302. The waste oil or fluid may then be drained into container 302. Cap 310 is removed from spout 308 and the oil from the portable receptacle 306 is subsequently emptied into the engine. Once receptacle 306 is emptied, dispenser cover 304 with mounted cap 310 is secured to container 302. Apparatus 300 may then be sent to the proper recycling plant if required.
