Abstract: A method of imaging an article comprising a metal/metal oxide imageable layer with a laser beam. In particular, the present invention relates to a method for imparting a color image on the article. The method includes: a) providing an article including a substrate and an imageable layer, the imageable layer comprising a metal/metal oxide layer; b) imagewise applying a laser beam to the article; and c) in the portion of the article having the laser applied thereto, imparting a color to the metal/metal oxide layer different from the color in the non-imaged portion. Preferably, the imageable layer comprises aluminum/aluminum oxide. Also presented are imageable articles, and the resulting imaged articles.

Abstract: A multilayer innerseal having a grip tab extending across the innerseal. Force applied to the grip tab is concentrated at the base of the grip tab and promotes a complete failure of the innerseal. In use, a substantial portion of the original innerseal remains adhered to the container to providing evidence of tampering and to frustrate efforts to reseal the container.

Abstract: A z-tab innerseal for a container and method of application involves an innerseal having a first sealing portion for sealing a first portion of an opening defined by an upper rim of a container, a second sealing portion for sealing the remainder of the container opening and a flap portion between the first and second sealing portions which is adapted to be grasped and pulled upwardly by a user to remove the innerseal from the container opening. An advantage of the flap portion is that it allows the innerseal to be removed without having to penetrate or scrape the innerseal with a sharp object such as a knife. A method of forming the improved innerseal includes providing a blank of stock material having a folded portion, cutting the blank to form an innerseal, mounting the innerseal onto the rim of a container and sealing the innerseal to the container by passing the assembly through a heating station.

Abstract: An easily removable innerseal for a container and method of application relates to an improved arrangement having a body portion adapted for fitting over the upper rim of a container and a flexible element attached to the body portion for a user to grip. The body portion is provided with a lower bonding layer, which includes a first bonding portion and a second bonding portion adhered to the first portion, and a layer to prevent fluid from passing therethrough. The bonding force between the first and second bonding portions is designed to be weaker than the bonding force between the bonding layer and the container. In addition, the rupture strength of the first bonding portion is less than either of the bonding forces.

Abstract: An improved innerseal for sealing containers includes a body portion having an upper surface and structure connected to the upper surface for grasping by a user, whereby the body portion may be removed from a container quickly and efficiently. The body portion includes structure for preventing passage of fluid therethrough, and structure adapted for bonding the body portion against the upper rim of the container with a first bonding force. The bonding structure has a first bonding portion for sealing against the container rim and a second bonding portion which is adhered to the first bonding portion with a second bonding force which is less than the first bonding force. Consequently, a first part of the first bonding portion will delaminate from the second bonding portion over the container rim and remain adhered to the rim, while a second part of the first bonding portion will remain adhered to the second bonding portion, thereby exposing the opening in the container when the grasping structure is pulled.
