In order to be able to set the bending stiffness of a composite material having at least two plies connected by a laminating agent, it is provided that a mixture of a first, curing adhesive and a second, non-curing adhesive is used as laminating agent, wherein the bending stiffness of the composite material is set by the mixing ratio of the two adhesives.

The invention relates to a lid (2) for closing a cup (1) along a peripheral sealing edge (10). Said lid comprises at least one aluminum film and an optionally multi-layered plastic layer which is co-extruded onto the aluminum film and has a closed predetermined tearing line (3). The invention is characterized in that the plastic layer is made of plastic based on polyethylene (PE) or plastic based on polypropylene (PP) and that the predetermined tearing line is introduced into the plastic layer preferably by means of a CO2 laser. In one embodiment, said predetermined tearing line (3) is provided directly in the region of the sealing edge (10). The invention also relates to a method for producing such a lid.

FIG. 1 is a top front right isometric view of a food container lid showing the new design; FIG. 2 is a bottom rear left isometric view thereof; FIG. 3 is a front view thereof; FIG. 4 is a rear view thereof; FIG. 5 is a left side view thereof; FIG. 6 is a right side view thereof; FIG. 7 is a bottom view thereof; and FIG. 8 is a top view thereof; and, FIG. 9 is an environmental top front right isometric view thereof, shown attached to a food container body and with the top layer of the food container lid shown partially peeled away from the lower layer of the food container lid. The broken lines are shown for the purpose of illustrating environmental subject matter of an exemplary food container and form no part of the claimed design.

For a simple, fast, safe and reliable determination of the layer thickness of a bonding layer between two layers of a packaging, a laser ultrasonic method is provided, in which the transit time of the ultrasonic wave through the first and second packaging layers (2, 3) is determined in advance, and a maximum (M1, M2, Mn) in the measurement signal (S) is sought, and the point in time of occurrence of this maximum (M1, M2, Mn) is determined as the total transit time (T1, T2, Tn) of the ultrasonic wave, and the transit time of the ultrasonic wave through the first and second packaging layers (2, 3) is subtracted from the total transit time (T1, T2, Tn), and the thickness (d) of the bonding layer is deduced from the known ultrasonic speed (vS) in the bonding layer (5).
摘要:
A bottle, especially a pharmaceutical bottle, configured to facilitate the withdrawal of goods present in the bottle in the form of pieces, the bottle being closed by a lid that consists of at least two layers: a cover layer and an outer layer. The cover layer, which may be a multilayer structure, is firmly sealed to the peripheral, circular sealing edge of the pharmaceutical bottle along said sealing edge, and includes a separation line off-set from the center of the circle. The outer layer, which may also be a multilayer structure, is connected to the cover layer across the entire surface thereof in such a way that one layer can be peeled off. The separation line of the cover layer has a concave section in the portion thereof that is next to the sealing edge, so as to form a flap section when the outer layer is peeled off.

A lid (2) for closing a cup (1) along a peripheral sealing edge (10) and a method for producing such a lid. The lid includes at least one aluminum film and an optionally multi-layered plastic layer which is co-extruded onto the aluminum film and has a closed predetermined tearing line (3). The plastic layer is made of plastic based on polyethylene (PE) or plastic based on polypropylene (PP), and the predetermined tearing line is introduced into the plastic layer preferably by means of a CO2 laser. The predetermined tearing line (3) may be provided directly in the region of the sealing edge (10).
摘要:
A lid for a pharmaceutical bottle that is configured to facilitate the withdrawal of goods present in the pharmaceutical bottle in the form of pieces, the lid including at least an inner layer and an outer layer. The inner layer, which may be a multilayer structure, is firmly sealed with and along the peripheral, circular edge of the pharmaceutical bottle and has a peripheral weakened line off-set from the center of the circle, where the peripheral weakened line of the opening has a concave section in the portion thereof that is next to the sealing edge. The outer layer, which may be a multilayer structure, is connected to the inner layer and can be peeled off such that the portion of the inner layer lying inside the peripheral weakened line remains on the outer layer, thereby forming an opening in the inner layer.
