The present invention relates to a mobile device for storing and cooling food objects. The present invention also relates to a method for storing and cooling at least one food object, and the use of the device for storing and cooling at least one food object.
Many food objects, such as meat and milk, need to be stored at a low temperature to prevent these objects from decomposing too quickly. This imposes a problem when refrigerators cannot be used. A common solution used on camping sites is classical cooling boxes and bags, where the cavity of the box or bag is cooled electrically or by use of ice blocks and the like. During outdoor activities however, such as fishing and camping in the wild, such boxes are often not available or cannot be taken along due to their large volume and weight. Preventing food objects from going bad during such outdoor activities, especially at warm outer temperatures, is a problem.
It is known that cold water can be used to prevent food objects from decomposing. U.S. Pat. No. 2,350,883 discloses a method for storing goods to prevent them from decomposing over time by storing the goods into large containers under water for a long time. A weight is attached to the container for keeping them submerged. A line is used for connecting the container to a holding object such as a boat, a buoy or an object at shore.
However, no storage devices are available, which can efficiently and conveniently be used during outdoor activities. There is still a need for a more efficient and cost effective method to store and cool food objects during outdoor activities, when no refrigerator or cooling boxes can be used. There is a need for a storage device, which is small, low weight and easy to carry and handle during outdoor activities.
It is an object of the present invention to provide a device for storing and cooling food objects suitable for outdoor activities, such as fishing and camping.
This object is achieved by a mobile device as defined in claim 1.
The device comprises a first bag defining a first cavity configured to store at least one food object and a second bag attached to the first bag and defining a second cavity configured to store at least one weight for sinking the device below a water level, and the device is designed to enable a line to be attached to the device for securing the device when it is below the water level.
The device according to the invention is lightweight and can be folded or rolled into a small package when not used, which requires little space. Thus, the device is easy to carry when travelling on foot, in a canoe, or on a bicycle. The weight, which for example is a stone, can be put into the second bag just before the bag is to be immersed in the water. Thus, it is not necessary to carry the weight during the travel.
An advantage of the device according to the invention is that it comprises of a minimum of parts that are attached to each other, which improves convenience of use of the device during outdoor activities. The parts are attached to each other and can therefore be easily and quickly used without the need for assembling the device before use. The device is easy to manufacture at low cost.
The device comprises an opening or protrusion to enable a line to be attached to the device.
According to an embodiment of the invention, the first bag and the second bag are made of flexible material. Flexibility of the material improves convenience when inserting objects and weights into the outer bags. For packing the storage device, when it is not used, it is preferably folded or rolled into a small package. According to an embodiment of the invention, the first bag and the second bag are made of durable material. The durability is needed because the device may be pulled over stones and the like on the bottom of a sea or lake. Durability also improves the re-usability of the storage device.
