  • bread used in the present patent application comprises an edible flour product which is produced by baking, boiling or steaming bread dough to form a loaf of bread.
  • the loaf made from the bread dough is often too large and inconvenient to be eaten directly and is therefore often cut into slices before consumption by the consumer.
  • the bread is sliced by a shop assistant prior to being sold in a shop, such as for example in a bakery.
  • conventional bread-slicing devices which are known per se, such as, for example, a slicing machine with progressive lever, are used.
  • the standard bread-slicing device comprises bread-slicing means with serrations or slicing wire for slicing the unsliced loaf.
  • the shop assistant places the unsliced loaf in the bread-slicing device.
  • the assistant then activates the bread- slicing device, following which the loaf is moved in the direction of the bread-slicing means which cut the loaf into slices, resulting in a sliced loaf, after which the sliced loaf is moved to a discharge position.
  • the loaf is then taken from the bread-slicing device by the assistant and placed on a packaging plateau intended for the purpose.
  • the assistant pulls a bag over the loaf and the plateau, subsequently slides the loaf with the surrounding bag from the plateau, and then closes the bag.
  • a single packaged sliced loaf is provided, which can then be sold to the customer.
  • the bread-packaging device for packaging a single sliced loaf, according to Claim 1 .
  • the bread-packaging device according to the present invention comprises a conveying unit which can be placed near a bread-slicing device or can be connected or attached thereto and which is configured to receive a single sliced loaf from the bread-slicing device.
  • a conveying unit which can be placed near a bread-slicing device or can be connected or attached thereto and which is configured to receive a single sliced loaf from the bread-slicing device.
  • the bread-packaging device furthermore comprises a packaging unit which is connected to the conveying unit in such a way that a passage for the single sliced loaf is formed between the conveying unit and the packaging unit.
  • the packaging unit directly adjoins the conveying unit. As a result thereof, it is no longer necessary to move the loaf to a packaging plateau.
  • the conveying unit is configured for conveying the received single sliced loaf of bread to the packaging unit via the passage.
  • the packaging unit is configured for packaging the single sliced loaf received from the conveying unit in a bag.
  • the packaging unit comprises bag-opening means which can be brought into a first state for receiving a bag.

  • the bag-opening means are thus configured for opening the bag in such a way that it is situated with an opening of the bag in front of the passage, and the single sliced loaf can be moved into the bag by means of the conveying unit.
  • the bread-packaging device is configured in such a way that, for each loaf to be packaged, the bag-opening means have to be brought to the second state by a user in each case.
  • the packaging process for each loaf to be packaged is in each case initiated by the user. This ensures that a loaf is only packaged when a user actually requires one.
  • the bread-packaging device may in this case be configured in such a way that the bag-opening means in each case have to be returned to the first state by a user.
  • the bag is taken onto or near the bag- opening means and the bag is then opened in order to place the loaf in the bag.
  • the loaf is put in position, so that afterwards the bag can slide over the plateau and the loaf.
  • the prior art provides a relatively clumsy way of packaging a loaf. After the loaf has been sliced, the prior art requires the user to manually move the sliced loaf to a packaging position in order to bag the sliced loaf. After the loaf has been brought into position, the user has to take a bag and pull it over the loaf, following which the bag has to be moved by hand to a bag-sealing means.
  • the present invention provides a device in which fewer operations are required from the user in order to package a loaf.
  • An additional advantage thereof is that the present invention provides a relatively quick and simple way of packaging bread. In this case, the user does not have to touch the single sliced loaf in order to bag it, which is advantageous from the point of view of hygiene.
  • the inventor also had the insight that the present invention makes the packaging process simpler and also safer, because the user only has to bring the bag- opening means to the second state in order to package the sliced loaf. This may be effected by hand, or automatically by, for example, pressing an operating button.
  • moving the bag-opening means is initiated in particular by the user. It is conceivable that the user places the bag on or near the bag-opening means himself, but in an alternative embodiment this may also be effected automatically.
  • This makes operation of the packaging device more accessible for a larger group of users, including users which are not trained to operate a packaging device. Thus, it is for example conceivable to make customers in a bakery or in a supermarket slice their bread themselves and to bag it immediately thereafter using the bread-packaging device according to the present invention.
  • a further insight of the inventor is based on the fact that the inside of a loaf is less susceptible to ambient air when the loaf is unsliced than when the loaf has been cut into slices.
  • the inside of an unsliced loaf is subjected to contact with the environment, that is to say the ambient air, to a lesser degree.
  • the ambient air to a lesser degree.
  • relatively large openings are created between the slices, thus increasing the contact area with the air.
  • the present invention further enhances this effect by providing a bread-packaging assembly, comprising a bread-slicing device and a bread-packaging device according to the present invention, since this ensures that a loaf to be sliced is only sliced and packaged when a user actually requires it.
