Capsule made of aluminum, suited to seal small tubes with open hole by using a capsule made of the same metallic material as the tube, the capsule being useful in the recycling of its materials after their end use; the capsule including: a cylindrical body made of aluminum, derived from the pressure received from the punch during cavity formation; a thread, imparted within the wall of the capsule, in turn imparting a thread on the outlet of the present small tube with open hole; at least a seal, installed on the internal side of the upper face of the capsule, isolating the product contained within the small tube and to increase the sealing properties of the package; and at least a lower band, adapted to represent a security seal so as to distinguish the capsules that have already been unscrewed from those that are still new.

Method for manufacturing a capsule made of aluminum for small tubes with seal, suited to perforate a security seal made of aluminum, present on the hole of the small tube, the method including: studying the physical properties of treated aluminum; analyzing the treated material; extending/stretching an aluminum sheet, engaging it within a die adapted to maintain it in position during the molding steps; molding the capsule equipped with breakage pyramid, using a progression mold which, through passages, is adapted to sculpt and model the aluminum sheet up to reaching the desired shape; removal of the modeled capsules, from the remains of the aluminum sheet that was left intact during the progression molding; quality control, carried out randomly; cleaning of the molded capsules by air jet; painting of the capsules; drying of the capsules; and storage of the capsules.

An apparatus and methods of forming a metallic closure for a metallic bottle are provided. The present disclosure provides a pre-formed metallic closure and apparatus and methods of forming the metallic closure. The metallic closure can be reformed with a peripheral channel before the metallic closure is positioned on a metallic bottle. An inner tool and an outer tool can form the channel in one operation. Optionally, a thread can be formed on a metallic closure prior to use of the metallic closure to seal a metallic bottle. A capping apparatus of the present disclosure uses less force to seal a metallic bottle with a metallic closure of the present disclosure compared to the force required with a prior art ROPP closure. Accordingly, a metallic closure of the present disclosure can seal a metallic bottle formed of less material (such as by being thinner) than prior art metallic bottles.

A method for manufacturing a cap, which can insert a sheet member easily into a predetermined position of an upper part inside a cap body, without causing deformation to the sheet member or the cap body. The sheet member does not separate when a container is brought to reduced pressure. An annular protruding portion protruding on a lower surface side is formed in an annular flat region of a sheet member of an inside plug. After or at the same time that the sheet member is inserted into and installed at a predetermined position within a cap body, the annular protruding portion is pressed axially toward a top panel wall and deformed so as to become close to a flat shape, to enlarge the outer diameter of the sheet member. The inside plug is thereby held to be inseparable from inside a skirt wall and to be axially movable.
