  • Patent number: 4564116
    Abstract: A bottle closure cap stampable from sheet metal as a shallow cylindrical inverted dish having a rounded juncture forming a fillet between its crown and its cylindrical wall; a layer of elastomeric material being disposed in the fillet and engageable with the axial end of the bottle when the cap is attached. A generally radially extending rip tab is integral with the cylindrical wall at the bottom edge thereof and is adapted to tear through the cylindrical wall by a generally circumferential pull of the user to gain access to the container. A rip line is provided commencing at a corner defined by the bottom edge of the cylindrical wall where it meets the rip tab. At least one groove is formed in the rip tab extending in the inner surface of the side wall. The rip line extends at a shallow angle across the cylindrical wall, without crossing the groove, continuing to a level which is spaced below the crown, continuing parallel to the crown circumferentially about half-way around the closure cap.

  • Patent number: 4513883
    Abstract: A disposable oil can having displacable tab portions on the top and bottom lids, with a connecting rod lodged between the tabs. According to this arrangement, the oil can can be opened manually by pressing downwardly on the upper tab portion to cause the lower tab portion to open for drainage directly into the crankcase of an automobile without utilizing a pour spout. In an alternate embodiment, the upper pre-scored tab portion opens upwardly, and the lower pre-scored tab portion opens downwardly. A pivot bar is attached to the lower tab portion and is coupled to the upper tab portion so that upward movement of the upper tab causes downward rotation of the lower tab portion.

The closure includes an outer retaining ring portion and an inner sealing plug portion which are preferably initially molded as a unitary product, but wherein the sealing plug portion is connected to the ring portion primarily by a rupturable connecting line. The retaining ring portion is interlocked with an extreme end of the neck finish of a container and the sealing plug portion is interlocked in sealing relation with an internal shoulder of the container neck finish, which shoulder defines a pour opening. The sealing plug portion is retained in association with the retaining ring portion by a hinge strap which is elongatable under tension. The sealing plug portion is also provided with a vent opening which is normally closed by a vent valve which is held in its closed position by internal pressure and which is movable manually to a vent position.

    Abstract: A closure for containers which is inexpensively and easily manufactured and is readily removeable in whole or in part to gain access to contents in the container. The closure comprises a generally flat cap member sealed at its periphery to the mouth of the container. An upstanding tubular member on the surface of the cap is partially surrounded by a score line in the cap and the score line preferably continues all around the cap near its periphery. The tubular member preferably has rigidifying means in its closed top and side walls which can be readily flexed inwardly so that the tubular member can be firmly grasped and pulled to readily initiate a rupture in the score line at a stress-concentrating focal point on that portion of the score line adjacent the tubular member. The cap can then be easily removed by continued pulling of the tubular member.

    Abstract: This specification discloses certain improvements in resealable pressure releasing closures of the type disclosed in U.S. Pat. Nos. 4,105,134 and 4,155,480 Debenham et al. In the several improvements disclosed in the specification, the resealing properties of the closure are improved by reducing the concentration of the flexure of the closure at the connection between the closure and the can end to thereby reduce the extent to which the material defining the connection permanently deforms during the opening operation. In one embodiment the pressure releasing closure or tab 20 has a connection 23 to the can end which is at substantially the same level as the adjacent portion of the closure by the provision of an area 26 immediately behind the connection which is downwardly depressed so as to be co-planar with the tab 20.

  • Patent number: 4014455
    Abstract: An end cover or closure for an accurate pour style container that is particularly well suited for use with non-viscous liquids has included thereon a displaceable portion proximate the periphery which prescribes an opening in the cover that is size-limited by means of a short score in the panel having reversely-curled ends, there being a non-detachable pull tab attached to said displaceable portion with a pull ring for the tab disposed radially inwardly from the point of tab attachment; the tab and the displaceable portion of the cover when opened being adapted to pivot through about 90.degree. with the tab then assuming a thus stopped position generally perpendicular to the container end panel adjacently neighboring the side wall of the enclosed container so that the extended open tab can thereupon function as a very effective and efficient pour guide for effluent during container discharge.

  • Patent number: 4002262
    Abstract: An improved vented, easy-opening end closure having an opening score line and a vent score line and a pull tab provided with an integral tether secured to the end panel and operative to effect, in the areas immediately adjacent the ends of the vent score line, primarily tension stresses and to reduce the stress components normal to the end panel which tear the end panel and thus frustrate opening of the container.

  • Patent number: 3970212
    Abstract: An easy opening ecology end having retained vent and pour tear strips is formed by an end wall having two lines of weaknesses. One line of weakness defines a vent opening while the other line of weakness defines a pour opening. Attached to each of the tear strips is a tab including a body member and end portions, the tab being attached to the respective tear strips by rivets. Each line of weakness terminates in a reversing curl to prevent continued complete separation of the tear strip. The lines of weakness, the reversing curves and the relative position and radii of the reversing curves cooperate to form a hinge line about which the ruptured tear strips are folded such that the tear strips are retained and folded back against the end wall.

  • Patent number: 3951299
    Abstract: An improved easy-open end closure has a generally C-shaped ancillary scoreline in the end panel closely adjacent a rivet which is positioned between a piercing portion of a tab to which it is attached and at least a portion of the rupturable ancillary scoreline. The peculiar shape of the scoreline, with its inwardly looped ends, facilitates movement of the handle portion of the tab away from the end panel by rendering the adjacent portion of the end panel more flexible and minimizes tear out of the flexing portion of the panel by substantially eliminating areas of stress concentration.

  • Patent number: RE30349
    Abstract: This disclosure describes an easy-opening container wall having a wall segment at least partially removable therefrom. A tab is secured to the container wall for initiating severance of the wall segment from the container wall. A rupturable scoreline is formed in the container wall adjacent the tab and rupturable in response to movement of the tab to initiate severance of the wall segment from the container wall.
