Abstract:
The present invention relates to a flexible membrane lid for a container comprising a top paper layer which is perforated to form a perimeter of at least one peelable portion and a bottom film layer. In some embodiments, the bottom film layer is partially adhered to the top paper layer, wherein the layers are not adhered within the perimeter of the peelable portion. In other embodiments, the layers are adhered with a pressure sensitive adhesive within the perimeter of the peelable portion and with a permanent adhesive in the remainder of the area between the top paper layer and bottom film layer. In other embodiments, the invention relates to a flexible membrane lid for a container comprising a top paper layer comprising a pull tab and a bottom film layer which is removably adhered to the top paper layer, wherein bottom film layer comprises a separate pull tab.
Abstract:
A sealable enclosure is disclosed that is configured to enclose an object that is to be heated, wherein heating of the sealable enclosure with the object sealed therein permits gas generated by the heating to vent out through a first micro-pore portion disposed in a fold of film layer. Initially, the generated gas is retained in the sealable enclosure. When the temperature of the strip of heat sensitive adhesive reaches a threshold temperature, the strip of heat sensitive adhesive releases so that fold opens, wherein the gas vents through the micro-pore portion disposed in the film layer out into an ambient region surrounding the sealable enclosure while preventing ambient contaminates in the ambient region from entering into the sealable enclosure.

Abstract:
The present invention relates to container laminate and container having a container laminate through which materials may be accessed and/or dispensed. The laminate has multiple layers that are peeled away when opened to reveal one or more openings in a layer that remains adhered to the container after opening.
Abstract:
The present invention relates to a storage container for liquids, comprising a liquid-tight tank with an upwardly directed opening, wherein the opening is closed in a leaktight fashion by a protective film comprising an outer layer and an inner layer, wherein the outer layer is an aluminium foil and the inner layer is a plastic film, wherein the outer layer can be removed from the storage container separately from the inner layer, and wherein the inner layer can be pierced by a hollow needle; an assembly comprising at least two storage containers according to the invention; and a method for producing the assembly according to the invention, comprising the steps of providing at least two storage containers according to the invention, and applying a continuous layer of an adhesive film on the outer layers of the protective films of the at least two storage containers.

Abstract:
Sealing (peel seal) membranes for packaging aggressive or chemically reactive products such as hair colorants over long periods without seal failure are described. Advantageously, the membranes and other packaging components have a high resistance to chemical attack and exhibit other advantageous characteristics, such as good barrier properties that minimize or eliminate interaction with the external environment, chemical inertness with respect to the product, and desirable heat sealing properties for prolonged adhesion without cracking and/or product leakage. The membranes comprise an inner bonding layer comprising a blend of polyethylene (PE) with an anti-cohesion additive, and a barrier layer.
Abstract:
The invention provides a container (40) of the type to hold fresh food or produce. Container (40) has a base (42) and a lid (44) moveable with respect to the base (42) between an open position and a closed position. The lid (44) has a first planar area (54). The base has a second planar area (56). In the closed position, the first planar area (54) and the second planar area (56) include a substantially flat area suitable for receipt of an adhesive membrane, such as a self-adhesive label. The substantially flat area includes an edge (55) of the first planar area (54) and at least part of the second planar area (56).
Abstract:
The invention concerns a tube with a plastic neck and with a cover to be welded over the neck after its cap has been fixed, the cover having at least one projecting portion for pulling it off, with cap holding the cover while it is being sealed over the neck. The cover has one or more projecting tabs, at least one of which is used to pull off the sealed cover and the cover is deformable and has little or no resilience. The end of the cap has a shoulder to press the cover onto the neck, which shoulder is configured so that it does not bear on the burrs of the neck, and the neck and cap have space between them for the bent back projecting tab or tabs of the cover. The invention also concerns a method of sealing the tube by induction or ultrasonic welding. The invention is used for the packaging of toiletries, cosmetics or food products.
