A method serves for determining an object weight of an object that is put on a weighing zone, which has a plurality of weighing plates arranged in a grid pattern, of a household refrigerator. The respective weights are measured by the weighing plates and an image is taken of the weighing zone. From the image, respective percentages of support surfaces of the object stored on the weighing zone in relation to the individual weighing plates are determined. From the weights measured at the weighing plates and the proportions of the support surfaces the object weight of the respective object is determined, and advantageously the determined object weight of the object is stored in a database. A refrigerating device has a household refrigerator with a refrigerating compartment having a weighing zone with a plurality of weighing plates arranged in a grid pattern. The refrigerating device is intended for performing the method.

The present invention is to issue a quality certificate on which a graphic image representing the quality in chronological order of a cooling environment in a container accommodating articles therein is printed on a recording medium, upon arrival of the articles at a delivery destination. A delivery unit 15 is mounted on a vehicle 21 and is used to deliver the articles accommodated in a storage container 33 filled with a cooling gas. The delivery unit 15 includes a thermometer Se1 that measures a temperature in the storage container 33, a memory unit 53 that memorizes therein data of the measured temperature in chronological order, a quality-data generation unit 55a that generates quality data of articles based on temperature data acquired from the memory unit 53, a print-data editing unit 55h that edits print data relating to a quality certificate including a graphic image representing the quality in chronological order of the cooling environment in the storage container 33 accommodating articles therein during delivery based on a serial number of the article and the quality data, and a printer 27 that prints print data relating to the quality certificate on a recording medium.

A fresh-keeping device for a refrigerator, and a refrigerator. The fresh-keeping device includes a fresh-keeping box body having a lower frame and an upper frame, the lower frame being provided with an accommodating space as well as an opening and a gas inlet communicated with the accommodating space, the upper frame being provided with a refrigerating air channel, and the refrigerating air channel being used for refrigerating the accommodating space; a drawer is configured to enter from the opening and accommodated in the accommodating space to fit the fresh-keeping box body to form the sealed accommodating space; and a nitrogen generating means connected to the side of the fresh-keeping box body on which the gas inlet is formed and is configured to charge generated nitrogen into the accommodating space from the gas inlet.

A container apparatus can include a container and an insert assembly. The insert assembly can include four elongate members. The four elongate members can include light emitting devices for illuminating the interior of the container and/or temperature altering elements for cooling and/or heating the interior of the container. The container can have a rectangular base and a rectangular sidewall extending upwardly from the base. The sidewall can define four corners of the container, and four elongate recesses can be formed in the sidewall proximate the four corners of the sidewall to receive the elongate light members. The recesses can be sized and shaped to conform to the elongate insert members so that the insert members can be releasably retained within the elongate recesses.
