摘要： Improved easy opening means for containers. Especially adapted to those used for liquids, including carbonated beverages, and permitting drinking from the container or pouring out contents. An important feature is attachment of closure to container after opening to avoid litter. Another feature is lift tab for easy opening, and with closure sealed by either a frangible adhesive sealant or by membrane sealing means. Lift tab initiates rupture of sealant, and then is pushed below container top with means to hold tab below opening so there is no interference when drinking from the can. Another closure has a small end for initial pressure release, and then whole closure hinges inwardly. Still another means comprises a slide gate with frangible membrane for sealing and for very easy opening. Optionally a pressure release button is provided to release the internal pressure before pulling the slide gate. An improved forming method for making the opening smaller than the closure where the closure is cut from the ductile metal top material. Partial use of score lines is included. Container top may be of ductile metal or of plastic for some of the designs. Primary objectives are the elimination of separate closure device that would cause litter, closure easier to open than heretofore, low cost, and no danger of a piece coming loose inside container.

摘要： Improved easy opening means for containers. Especially adapted to those used for liquids, including carbonated beverages, and permitting drinking from the container or pouring out contents. An important feature is attachment of closure to container after opening to avoid litter. Main feature is an openable segment in the top defined by a score line that extends almost all around its periphery, but interrupted at one point by an unscored section which provides hingeable attachment means to secure the segment to the top within the container after opening. Opening of the segment is accomplished by a manually operated elongated leverage lift tab which is hingeably secured to the top by a rivet which is positioned just outside of the segment and close to the score line. The outer longer lift end of the lift tab extends over the container top beyond the segment, and the shorter inner end extends partially over the segment, and comprises a downward pressure exerting extension. When the lift end is raised, the inner end exerts high downward pressure near the score line, thereby rupturing the score line with the rupture starting near the pressure point and extending on around the periphery, and the segment is thereby hinged down into the container where it remains attached to the top by the hingeable unscored section. The lift tab is then folded back out of the way to a position just above the container top, and ready for drinking from the can or pouring out the contents. Container top may be of ductile metal or of plastic. Primary objectives are the elimination of separate closure device that would cause litter, closure easier to open than heretofore, low cost, and no danger of a piece coming loose inside container.

摘要： Relates to easy opening container tops in which there is a tear strip which remains attached to the container after opening. The tear strip has an elongated U-shape, with a ring tab attached at the end of the loop which is near the outer border of the container top. The inner end of the tear strip has an unscored section which serves to hold the strip attached to the top after opening. Stiffening, such as ribbing, is provided in the tear strip to keep it fairly flat during and after opening, and to provide protection against the sharp edges. A cavity is provided in the top into which the strip partially folds to be out of the user's way. Small ribe alongside the rivet that attaches the pull ring, and in the unscored attachment section, serve to prevent the material of the top at these points from bending too sharply, and possibly breaking off. The inner end of the opening may curve to one side so the strip in the opened position will clear the user's nose when drinking from the container.

摘要： Improved easy opening means for containers. Especially adapted to those used for liquids, including carbonated beverages, and permitting drinking from the container or pouring out contents. An important feature is attachment of closure to container after opening to avoid litter. One closure design has lift tab attached to the closure for easy opening, and with closure sealed by either a frangible adhesive sealant or by membrane sealing means. Lift tab initiates rupture of sealant, and then both lift tab and closure are pushed below container top with means to hold tab below opening so there is no interference when drinking from the can. Another closure has a small end for initial pressure release and starting rupture of sealing means, and then whole closure hinges inwardly. Still another means comprises a slide gate with frangible membrane for sealing and for very easy opening. Slide gate is non-detachable and has sharp points for easier rupture of membrane during opening. Optionally a pressure release button is provided to release internal pressure before pulling the slide gate. An improved forming method for making the opening smaller than the closure where the closure is cut from the ductile metal top material. Partial use of score lines is included. Container top may be ductile metal including aluminum or steel, or of plastic for various forms of the invention. Primary objectives are the elimination of a separate closure device that would cause litter, closure easier to open than heretofore, low cost, and no danger of a piece coming loose inside container.

摘要： Improved easy open means for containers. Especially adapted to those used for liquids, including carbonated beverages, and permitting drinking from the container or pouring out contents. An important feature is attachment of closure to container after opening to avoid litter. Main feature is an openable segment in the top defined by a score line that extends almost all around its periphery, but interrupted at one point by an unscored section which provides integral hingeable attachment means to secure the segment to the top within the container after opening. Opening of the segment is accomplished by a manually operated elongated leverage lift tab which is hingeably secured to the top by a rivet which is positioned just outside of the segment and close to the score line. The outer longer lift end of the lift tab extends over the container top beyond the segment, and the shorter inner end extends partially over the segment, and comprises a downward pressure exerting extension. When the lift end is raised, the inner end exerts high downward pressure near the score line, thereby rupturing the score line with the rupture starting near the pressure point and extending on around the periphery, and the segment is thereby hinged down into the container where it remains attached to the top by the hingeable unscored section. The lift tab is then folded back out of the way to a position just overlying the container top, and ready for drinking from the can or pouring out the contents. Other features include various lift tab pressure exerting means, depression in top for lift tab, angular positioning of lift tab for improved rupturing and less obstruction to the user, part of score line replaced by adhesive sealing for easier initial rupture, various means for stiffening segment and top, stronger tab hinge means, separate downward pressure points for start and finish of rupture, supplementary score line groove on underside of top.
