The present invention provides a dispensing container comprising a vessel, the vessel having: a formation and/or discrete element in or on the vessel which causes the centre of gravity of contents of the vessel to be positioned differently, when oriented in a lain-on-side attitude, from its notional position, in the absence of the formation or element in or on the vessel; an additional formation or discrete element in or on the vessel which, when the container is in the lain-on-side attitude, lifts at least a portion of the container away from a surface, wherein, when the container is in the lain-on-side attitude and has a first volume of content, the centre of gravity of the content biases the container to a first orientation, and when the container is in the lain-on-side attitude and has a second volume of content, the centre of gravity of the container biases the container to a second orientation, different to the first.

A system for managing containers includes a server, a portable electronic device and a check apparatus. The server stores a piece of transaction data. The portable electronic device is configured to receive the piece of transaction data from the server, to determine whether a shaking criterion is met based on acceleration of the portable electronic device, and to display a barcode corresponding to the piece of transaction data when the shaking criterion is met. The portable electronic device is further configured to capture an image and send the image to the server. The check apparatus is configured to read and decode the barcode, and to display information relating to the piece of transaction data based on data encoded in the barcode.

A contact lens package includes a sealed contact lens package and a wrap coupled to the sealed contact lens package. The wrap has one or more panels. One of more of the panels includes a printed surface that includes a unique device identifier, which is provided in both human readable form that includes numbers or letters, or both, and machine readable form, such as a bar code. A method of manufacturing a contact lens package includes providing the sealed contact lens package and coupling the wrap to the sealed contact lens package.
