  • Self-weighing expandable bag
    Patent number: 11319113
    Abstract: A self-weighing expandable bag includes an inner receptacle that can slide vertically within an outer sleeve under the weight of bag contents. One or more springs, which may include coils and/or elastic fabric, connect the inner receptacle to the outer sleeve. One or more bag handles are attached to the sleeve. As the weight of the contents of the receptacle increases, the receptacle slides down within the sleeve and increasingly protrudes under the sleeve, expanding the vertical extent of the bag and revealing graphical markings underneath the sleeve and/or within a window defined in the sleeve.
