Definitions

• the present invention refers to a storage device for a fatty food product.
• Certain solid food items such as butter is traditionally kept in a refrigerator or in an area in a building with a relatively low ambient temperature to maintain the food product in a substantially solid form and also to prolong the storage life.
• the butter in order to make the butter easy to use, such as to spread on a sandwich, or to measure in during baking, it is also preferred in many situations that the butter can be set to a required serving temperature.
• the time when the butter is at an ideal serving temperature does typically not coincide with when the butter is actually required during the meal.
• the storage device comprises a closeable container, a means for maintaining a predetermined temperature with the container irrespectively of the ambient temperature and an internal power source.
• the storage device further comprises a thermoelectric module.
• One object of the present invention is to provide a storage device suitable for a fatty food product such as butter or cheese that allows an easy temperature control during storage and also tempering before serving.
• Another object is to provide a storage device that allows a good food hygiene.
• Yet another object is to provide a storage device that allows the consumer to control the amount of butter removed or remaining in the storage device.
• a storage device for a fatty food product comprising: a housing, a closeable food container, a tempering unit and a control unit, wherein the closeable food container is configured to contain the fatty food product and to be removably arranged in the housing; the housing comprises an insulation and a cooling box, the cooling box being configured to removably receive the closable food container; and the tempering unit is configured to control the temperature of the interior of the closable food container based on a signal from the control unit.
• the storage device is characterized by that the storage device further comprises a scale configured to communicate, to the control unit, a detected weight information relating to the fatty food product to be contained in the closable food container; and that the control unit is configured to process and communicate information relating to the detected weight information of the fatty food product to a consumer.
• fatty food product should be understood to encompass any fatty food product having a substantially solid structure at room temperature.
• the term should be understood to include any animal or vegetable fat based product, such as butter, margarine or cheese.
• the term“scale” should be understood as an arrangement that is configured to detect weight information.
• the detected weight information relates directly or indirectly to the weight of the fatty food product.
• the weight information is detected by the scale comprising at least one load cell configured to act as a detector.
• a storage device that first of all can ensure that the fatty food product, by the tempering unit may be stored at a proper temperature to ensure expected life length and a good food hygiene.
• the storage device comprising a scale
• the consumer may receive information relating to the amount of fatty food product present in the closeable food container. Since the information, by the scale, relates to detected weight information, this information can be presented to the consumer in a number of ways.

• the type of information and the way of presenting it to the consumer is determined by an inherent logic provided by the control unit.
• the fatty food product will have a temperature, which may be chosen to correspond to a desired serving temperature and also to a desired storage temperature.
• the control unit may be configured to allow the consumer to set one or both temperatures.
• the temperatures may be freely chosen by the consumer, or by selecting one or several preset set-point temperatures.
• This allows a pleasant presentation to the consumer during serving in terms of visual appearance and also texture wise. Further, it also reduces food waste in the long term since the risk of the butter getting too soft and smearing is greatly reduced.
