Car trash bag (CTB)

Abstract

The Car Trash Bag is a waste receptacle for installation inside a car and on the back of passenger or driver car seat to allow all passengers to dump in their trash. It comprises three parts, a) Lower Frame which fixes by headrest and always is in place and holds trash bag, b) Upper Lid which is an open top lid and entangles trash bag and c) Disposable Trash Bag which is a recycled plastic grocery bag or any kind of small trash bag. When the trash bag becomes full of garbage, the Upper Lid will be raised by removing it from Lower Frame and trash bag gets out from underside and a new trash bag will be replaced.

1 . A Car Trash bag is a waste receptacle which installs on the back of passenger or driver car seat. It comprises of three plastic parts.
 a) A Lower Frame CTB, this part has a main role in installation on a car seat and holding disposable plastic bag. It has two oval loops to adjust in all cars which grips by the poles of headrest and fixes by headrest in place. It has a U cross-section, semi-oval shaped circumference with a projection in its outer wall which entangles the disposable trash bag in contact with Upper Lid CTB. This U cross-section semi-oval shaped circumference reaches to two oval loops by two I cross-section blades. It has a finger knob to allow the consumer to open it.   b) An Upper Lid CTB, this part has a U cross-section, semi-oval shaped circumference which is match with Lower Frame CTB. It is an open-top part to allow the consumer to dump in waste and trash. It has an internal notch in its inner wall which latches with Lower Frame CTB projection and entangles a disposable trash bag in between. It has a finger knob to allow the consumer to open it.   c) A disposable plastic bag, which is a receptacle for trash and waste. It is thin and its open top circumference would be greater than 20 inches. For commercial purposes, it is possible to print some advertisements on its exterior.   
     
     
         2 . The Car Trash Bag of  claim 1 , wherein, the Lower Frame CTB and Upper lid CTB are made of flexible plastics like polypropylene or polyethylene or even ABS to refrain from breaking. 
     
     
         3 . The Car Trash Bag of  claim 1 , wherein, after installing this Car Trash Bag on a car seat all passengers can dump in trash in it. When its disposable trash bag becomes full, by parting the Upper Lid from Lower Frame by using finger knobs it is possible to remove trash bag from underside (the Lower Frame CTB is always in place) and replace a new trash bag and latch the Upper Lid CTB again. 
     
     
         4 . The Car Trash Bag of  claim 1 , wherein, is manufacturable and moldable and all Figs in this document are made by a 3D modeling software. 
     
     
         5 . This invention can easily use in other areas. By changing the Lower Frame CTB stands (oval loops) from horizontal to vertical stand and using vacuum cups, magnets and or other attaching instruments we will be able to install it on all walls for all transportation fleets like, airplanes, trains, public buses and so on. 
     
     
         6 . We can make this CTB bigger with proper attach-to-wall device (like slider bracket, screw-to-wall type) and use it in kitchens, malls, hospitals, offices and any other public areas.
