Systems and methods to encode sounds in association with containers, as well as systems and methods to recognize encoded sounds associated with containers, are described. The containers may include various structures to encode sounds. Responsive to opening of containers, the various structures may emit the encoded sounds. An audio capture device may receive the encoded sounds, and a computing device may process the encoded sounds to identify audio signatures within the encoded sounds. The audio signatures may be matched with known audio signatures to identify the containers and/or information associated with the containers.

The claimed technical solution relates to devices installed on packages in order to unload the package contents.

The device for unloading of package contents arranged above the package outlet hole includes a tray with flanges, an outlet valve and a supporting element; at that, when folded, the tray is located under the outlet valve and is retained on the supporting element; and the outlet valve is equipped with flaps allowing to retain the tray flanges and form an opening when the tray is put into an open position. At that, the tray is designed so that it can be opened at an angle exceeding 90°, and the edges of the tray flanges are free from any attachments on three sides thereof. The tray has a pulling element with slots made on the supporting element. When folded, the tray is retained by the tray flanges located in slots made on the supporting element. Moreover, the flaps of the outlet valve retain the tray in a closed position on the supporting element.

A storage container (1) having a pour spout (7) that doubles as a measuring cup for dispensing a set amount of contents from the storage container. A user may manipulate the storage container to force the contents into the spout. The contents are prevented from falling or spilling out of the spout while the storage container is in an upright position.

A box with sealable dispenser system including a carton having a plurality of side walls, a dispenser including a sealing member, and a pour spout. The dispenser is configured on one of the plurality of side walls. The pour spout is configured to pivot between an open-position and closed-position and the sealing member is configured to temporarily seal the dispenser in the closed-position. The pour spout may dispense items such as cereal stored within the carton when in the open-position. The sealing member creates an insect-resistant seal and prevent items stored within from losing freshness.

Containers are provided which provide controlled dispensing for items such as saltshakers. Such containers can be produced in a simple and economical manner and can be adapted to different types of products, such as different types of salt. Such containers are particularly useful for dispensing fine salt.
