Abstract: An effective thread number in the thread section which is disposed on the mouth section of the bottle is formed to be 2.2. That is, the thread section is formed such that the thread section 13 should serve effectively in the mouth section such that an interval between a start position and an end position should be 2.0 to 2.5. In the bottle can member 11 which has such a thread section, an outer diameter of the thread section which is formed on the mouth section is 28 to 38 mm. Also, the thickness of the mouth section is 0.25 to 0.4 mm. The thread section which has the effective thread number 2.0 to 2.5 is formed by eight-thread per inch pitch. By doing this, it is possible to put the cap desirably.

Abstract: A resealable can end is provided including a neck (10) and a cooperating cap member (12) which can be sealed onto and removed from the neck, and is capable of containing product under pressure or vacuum if desired. This end may be added, by convention seaming methods, such as roll seaming or by appropriate adhesive, to a container body, or may be formed integrally with container bodies. The venting feature of the end will achieve a controlled release of differential internal-to-ambient pressure upon initial opening of the cap, and may also provide resealed containment of partial contents retained in the container, although the contents will no longer be under pressure or vacuum, as the case may be. The end may be applied to, or incorporated in, containers made of various material, such as aluminum, coated steel, or selected plastics.

Abstract: An easy-open, reseable closure assembly for a beverage can (10) comprises a metal lid (12) and two threadedly connected molded plastic closure elements (40, 60) with engageable annular reseal surfaces (46, 76). The lid is scored (30) to define a circular tear panel (28) and a hinge (32). The spout element (40) is attached to the lid (12) with the bottom surface of the cap element (60) directly above and aligned with the periphery of the tear panel (28). Rotation of the cap element (60) by a user ruptures the tear panel and pivots the tear panel (28) downward about the hinge (32), providing a passage through the spout element (40) for pouring and driking. Initial rupture and rupture propagation of the tear panel (28) is controlled by the spacing of the cap element (60) from the tear panel (28) and their configurations. When the cap element (60) is replaced on the spout (40), reseal surfaces (46, 76) engage.

Abstract: A method and apparatus is provided for forming a cap with a pouring spout for a container. A continuous web is fed to a spout inserting apparatus which inserts a spout directly into the continuous web. The continuous web may thereafter proceed to a label applicator which applies a label to the continuous web over the spout. Thereafter, the continuous web is moved past a dye and press wherein the cap is punched out of the continuous web and the edge is folded to form a cap. Thereafter, the caps are collected, oriented and directed to a point for subsequent use. Additionally, container bottoms may be made by the same method and apparatus. In such a case, the spout is not inserted into the web. Scrap is continuously removed after the caps are cut from the continuous web. The caps may be subsequently processed, i.e. attached to the tops and bottoms of containers.

Abstract: A method for forming a constant geometry and non-turbulent stream inducing pouring spout in the rim portion of an annular side-walled vessel. The method comprises the steps of: a) positioning the vessel within a clamp possessing a groove whose centerline forms a 90.degree. angle with the annular side wall of the vessel when the clamp is in place; b) placing inside the vessel a center plug possessing a radially extending groove whose centerline forms a 90.degree. angle with the annular side wall when the center plug is in place; c) aligning the centerlines of the grooves of the clamp and the center plug to form a straight line travel path; d) placing a pour spout former in the center plug portion's groove and causing the former to travel along the travel path and into contact with the rim portion of the vessel; and, e) further causing the former to travel along the travel path to yieldably deform the rim portion of the annular wall into the desired shape pouring spout.

Abstract: A machine for inserting pouring spouts in caps, provides for feeding the caps to an indexing work table through an inlet apparatus which coordinates the position of the caps with the position of the indexing table. Mounting apparatus is provided to mount the caps on the indexing work table, which table moves the caps in a coordinated sequence to work positions where the pouring spouts are inserted in the caps. The indexing work table then moves the caps to an outlet position where ejecting apparatus removes the caps with the inserted spouts from the indexing work table, the pouring spouts on the caps are placed in the desired position and the caps are properly oriented as the caps leave the area of the spout inserting machine. A pneumatic assembly provides for the delivery of the container tops to the indexing table and for transfer of the container tops with the inserted spouts away from the indexing work table.
