Abstract
Packaging containers for beverages, for example milk or juice, as well as blanks for producing the packaging containers, are often manufactured from paper-plastic laminate which, by fold forming and sealing, is given the desired container configuration, normally parallelepipedic. With the aid of a specifically designed pattern of fold or crease lines which divide the material into, for example, six side panels (1) and associated primary end panels (7) and secondary end panels (8), respectively, prismatic, preferably hexagonal containers may instead be produced using substantially known methods.
Claims21
A packaging container comprising:
- at least two main side wall panels and at least two other side wall panels, the total number of side wall panels being in excess of four;
- a first end region and a second end region;
- said first end region including two primary end panels adjacent said at least two main side wall panels and defined from said adjacent main side wall panels by crease lines, a plurality of secondary end panels which interconnect with the primary end panels and with the other side wall panels, and a sealing fin;
- and
- said sealing fin being arranged for sealing edge regions of both the primary end panels and the secondary end panels with one another in a continuous double layer seal over the entire flat-laid width of the packaging container.
A packaging container blank comprising:
- a central zone which comprises more than four quadrilateral side wall panels and a longitudinal sealing panel;
- and
- two end zones located on either side of the central zone, each of said end zones comprising a transverse sealing panel, at least one primary end panel and a plurality of secondary end panels disposed on either side of the primary end panel, said primary end panel forming an extension of a first side wall panel and said secondary end panel forming a continuation of at least two second side wall panels located in the central zone, wherein the transverse sealing panels are linear and continuous over the entire flat-laid width of the packaging container.
A packaging container comprising:
- at least two main side wall panels and at least two other side wall panels, the total number of side wall panels being in excess of four, the side wall panels being joined to one another along their lengths;
- a first end region located at one end of said side wall panels and a second end region located at an opposite end of said side wall panels;
- said first and second end regions including two primary end panels adjacent said at least two main side wall panels and defined from said adjacent main side wall panels by crease lines, a plurality of secondary end panels which interconnect with the primary end panels and with the other side wall panels, and a sealing fin;
- and
- said sealing fin being arranged at an edge of the primary end panels opposite said at least two main side wall panels and at an edge of the secondary end panels for sealing edge regions of both the primary end panels and the secondary end panels with one another in a continuous double layer seal over the entire flat-laid width of the packaging container.
