Abstract
A packaging unit from a moulded pulp material and a manufacturing method therefor. The packaging unit comprises a bottom part with product receiving compartments and a number of cones that are provided between the compartments, a cover part, a hinge configured for hingedly connecting the bottom part with the cover part, and ventilation bridges formed into the bottom part between adjacent product receiving compartments. The ventilation bridges provide void spaces in a bottom surface of the bottom part and allow for the continuous flow of air through the bottom part of the packaging unit.
Claims20
A packaging unit comprising:
- a bottom part with product receiving compartments and a number of cones that are provided between the compartments, and the bottom part comprising a bottom surface, two side surfaces, a back surface, and a front surface;
- a cover part comprising a top surface, two side surfaces, a back surface, and a front surface;
- a hinge configured for hingedly connecting the bottom part with the cover part;
- and
- at least one ventilation bridge on the bottom surface of the bottom part, the at least one ventilation bridge provided between two adjacent compartments and forming a void space in the bottom surface between the two adjacent compartments, the at least one ventilation bridge comprising two sidewalls and a top wall, wherein the two sidewalls extend upward from the bottom surface and include an upper arcuate portion adjacent the top wall.
A packaging unit comprising:
- a bottom part with product receiving compartments and a number of cones that are provided between the compartments, and the bottom part comprising a bottom surface, two side surfaces, a back surface, and a front surface;
- a cover part comprising a top surface, two side surfaces, a back surface, and a front surface;
- a hinge configured for hingedly connecting the bottom part with the cover part;
- and
- at least one ventilation bridge on the bottom surface of the bottom part, the at least one ventilation bridge provided between two adjacent compartments and forming a void space in the bottom surface between the two adjacent compartments, wherein a height of the at least one ventilation bridge is between 0.11 and 0.4 times a height of the bottom part.
A packaging unit comprising:
- a bottom part with a first row of product receiving compartments, a second row of product receiving compartments, and a number of cones that are provided between the compartments of the first and second rows, and the bottom part comprising a bottom surface, two side surfaces, a back surface, and a front surface;
- a cover part comprising a top surface, two side surfaces, a back surface, and a front surface;
- a hinge configured for hingedly connecting the bottom part with the cover part;
- and
- a plurality of ventilation bridges formed into the bottom part, wherein the plurality of ventilation bridges comprises a ventilation bridge positioned between each two adjacent compartments in each of the first row and each two adjacent compartments in the second row and a ventilation bridge positioned between each two adjacent compartments of the first and second rows;
- wherein a total combined width of the ventilation bridges in the first row of product receiving compartments is between 0.3 and 0.5 times a length of the bottom part.
The packaging unit of 16, wherein each ventilation bridge includes a height approximately between 5 and 10 mm and a width approximately between 15 and 25 mm, and a total void space area approximately between 90 and 140 mm2.
