Packaging unit with lock and adjusted label, and method for packing products

The present invention relates to a packaging unit (2) made of moulded pulp for products like eggs, and a mould and method therefor. The packaging unit comprises: a bottom part (4) provided with compartments (26) for individual products; a cover part (14) comprising top (24), front (18) and rear (22) surfaces with the front surface comprising one or more openings (29); a first locking element extending upwardly from the bottom part defining a cam (31) with an at least partly downwardly facing locking plane (156) with a length and a width, such that the length of the cam partly extends through the opening in the front surface of the cover part in a closed position of the packaging unit; and a label (36,50,60) provided on the cover part, wherein the label is provided with a curved cut (38,52,62) that is configured to enable the cam to partly extend through the opening in the cover part and remain substantially behind the label seen in a front view of the packaging unit in a closed position. By providing the label of the cover part with a curved cut at or close to the location of the first locking element in a closed position of the packaging unit, the packaging unit can be locked securely, while maintaining the front view of the label substantially intact. This provides an effective display surface to provide consumers with relevant information about the products inside the packaging unit, for example.
