An ice merchandiser for storing bagged ice for purchase by a customer is provided. The ice merchandiser includes a payment system for facilitating a bagged ice product transaction at the ice merchandiser. The payment system includes a mass determination module structured to determine a mass of bagged ice product removed during the bagged ice product transaction and a transaction module structured to determine an amount of currency required for the bagged ice product transaction based on the determined mass of bagged ice product removed.

Disclosed is an ultra-low temperature freezer comprising a seal. The seal member has: hollow first and second air layer forming portions which are aligned in a row in a second direction between a first and second peripheral edges when a door is closed; and a first connection portion which is connected between the first and second air layer forming portions so as to form an air layer. The first connection portion has a shape that would overlap part of the first and second air layer forming portions if moved in parallel to the second direction. The outer peripheral surface of the first connection portion and the outer peripheral surfaces of the first and second air layer forming portions form first and second recessed portions extending in a first direction.

The present invention relates to a refrigerator having a separate deep-freezing space which is partitioned inside a storage space of the refrigerator. Provided is a refrigerator having a flow path which allows cold air to circulate inside a deep-freezing chamber. According to an embodiment disclosed in the present document, a flow path portion is formed on one part of the inner surface of the housing which forms the inner space of the deep-freezing chamber. The flow path portion is formed in a stepped shape on the inner surface of the housing.
