Background of the invention
[0001] The present invention relates to a vacuum container for a vacuum food storage comprising
a vessel, a lid equipped with a valve for sucking air out of the vessel and a date
display system.
State of the art
[0002] Food storage allows food be preserved from spoiling for some time. Food preservation
is important in context of its wasting. Preservation prevents food from contamination
and extends the lifespan of the product. There are many ways of domestic and industrial
food storage and preservation. To ensure freshness of foodstuff in domestic environment
consumers use a fridge or refrigerator. It is also possible to pickle items in jars.
Typically the pickling procedure affects the foods texture and flavour. Pickling allows
the food to be stored for months. For storage everyday food a vacuum storage boxes
are known. The vacuum storage box technology is based on the vacuum production process
inside the container performed by sucking air out of the container to create a vacuum
inside the container. The process led to a significant reduction the number of harmful
bacteria and microorganisms and allow for even five times longer food storage and
preservation of its nutritional value. Additionally, this kind of food preservation
do not change the texture and the taste of the preserved food what is a great advantage.
Typically, vacuum containers have a valve placed on the container cover thanks to
which the air can be sucked out of the container. For this purpose a simple handheld
air pump is provided. Vacuum containers are also adapted to be stored in a refrigerator
or freezer at low temperature. It is also possible to heat the container with a previously
prepared meal by microwave oven. Other advantage is that thanks to creating a vacuum
inside the container a previously opened jar with e.g. jam can be re-secured against
spoiling. There are many advantages of using such technology: it preserves freshness
and natural taste, aroma and colour of food, ensures the absence of unpleasant odours
in the refrigerator. Extending the time for consuming food helps also to save money
and time. Vacuum containers can be provided also with data indicating systems for
setting the date of starting a food storage process or the expiration date of the
stored food.
