  • Patent number: 4339047
    Abstract: The invention relates to a collapsible transport and storage crate capable to be stacked. The sides (5) of the crate are provided with pins (13) sunk into connecting pieces (4) at the bottom of the crate. Upon folding down the sides they are lifted so that the pins (13) are pulled out of the connecting pieces (4) and are folded down hinged at them inward against the bottom. Thereby guide bosses (12) reach above the geometry of the folded-down crate and fix a crate located thereabove. In outfolded state tips (17) located on the upper edges of the sides can engage with pockets (15) located in the bottom of a crate thereabove and thereby fix said crate in lateral direction.

  • Patent number: 4299074
    Abstract: The invention relates to a method and an apparatus for compressing voluminous material easy to compress and for storing and transporting the material in said compressed state. According to the invention, thus, there are provided a bottom and two opposed vertical walls capable to approach each other for compressing the material between the walls. When the material has been compressed to the desired volume the material is transferred to a storage or transport crate, which is located with its floor beneath the bottom and with its sides outside of and adjacent the walls. When the material is being discharged between the walls, it expands and presses against the side of the crate and an end side connected to the crate whereby the crate is moved with the material while being successively filled. When the material is being compressed it is pressed downward by a belt acting from above on the material.
