Abstract: Disclosed is a plastic lid for a container, which has a mounting hole in the lid's center and an in-and-out hole that is tightly closed until opened for the first time, and which has a plastic opening mechanism that can additionally pivotally cover the in-and-out hole. The opening mechanism has a valve that has a hole around which there are at least two latches which interact with a knob that has an arm terminated with a cylindrical element that has at least one carrier and is able to rotate in the mounting hole. The valve and the knob are sealed and immobilized with a plastic foil. Once opened, the in-and-out hole can be covered again using the valve and the mouth contact area using a plastic hygienic cover.

Abstract: A pallet for transporting and storing preforms of plastic containers is composed of a frame (1) with a grill inside (2), fitted with hoop-shaped elements (3), which are interconnected to stands (4) holding preforms (8). The side walls of the stands (4) are formed in the shape of a truncated cone. The outer and inner diameters of the stand (4) are, at the point the stand (4) is interconnected to the hoop (3), appropriately smaller or equal to the outer and inner diameters of the hoop (3). The side walls of the stands (4) are lattice work in structure. The hoops (3) are interconnected to the stands (4) by way of a ring-shaped shelf (5) on which the preform (8) flange rests. In variant one the stacked pallets rest on supports (9) protruding above the upper edge of the frame (1), and in variant two they rest on the frame (1) edges.

Abstract: This invention is concerned with a plastic end closure of a container that is primarily intended for beverages. It consists of a body that is tightly attached to the container and an opening device that can additionally be used to cover the in-and-out hole. According to the invention, the end closure is characterised by that it has an in-and-out hole (3) in the body (1), which is tightly closed until opened for the first time using the valve (5) that has a hole around which, substantially perpendicularly to the hole surface, there are at least two latches (7) that are rotatably mounted in the mounting hole (4) from the inside of the end closure and interact with a knob (6) that has an arm (13) terminated with a cylindrical element (9) that has at least one carrier (10) on its side surface and is rotatably mounted in the mounting hole (4) from the outside of the end closure. The valve (5) and the knob (6) are sealed and immobilised with the help of the plastic foil (11).
