Patent number: 5054684Abstract: The invention relates to a package for liquid made of a coated cardboard composite, having a pierceable opening for a drinking straw, which has incisions 11 running towards one another in the form of rays or a star, and perferably a cutout 9 located at the star point of the incisions. An opening thus constructed for a drinking straw easily enables an arbitrarily concentric expansion of the star flaps located between the incisions, so that said flags rest sealingly on the drinking straw in each case. This guarantees for different drinking straws a uniform opening for the drinking straw which can be introduced into the multilayer cardboard composite both before it is coated and after it is coated.Type: GrantFiled: April 27, 1990Date of Patent: October 8, 1991Assignee: PKL Verpackungssysteme GmbHInventors: Jurgen Farber, Matthias Dammers

Patent number: 4930683Abstract: A parallelepipedal flat-gabled package, especially an eared package with a medial seam, having an area in the gable that has been prepared such that it can be penetrated or separated along a closed curve and, once it has been penetrated or separated, will constitute a pouring hole. The package also has a plastic pour-out structure that has a flange surrounding the pouring hole, rigidly secured to the outer surface of the gable, and into the spout of which can be axially inserted a tube with a circumference that matches the closed curve. It also has a number of triangular teeth along the surface that faces the pouring hole, and a cap that can be repeatedly employed to close the spout, the inner surface of the package being coated with a hot-adhering film of plastic. The closure-flap cap is securely attached to the tube, by way of a connecting strip, and is articulated to the tab on the pour-out structure, which is in the form of a spout.Type: GrantFiled: February 28, 1989Date of Patent: June 5, 1990Assignee: PKL Verpackungssysteme GmbHInventor: Jurgen Farber
