What is proposed is a closure unit consisting of a glass container (50) with external, circumferentially offset threaded elements (54, 55) on a container neck (52) of the glass container, and a closure cover made of sheet metal, wherein the closure cover (1, 2) has an encircling plastics layer (30; 30h, 30v) on the inside of the cover. The closure cover is pressed onto the container neck (52) and can be opened with a rotational movement via the threaded elements (54, 55) and a vertical section (30v) of the plastics layer. The container neck (52) has a horizontal end surface (52a) on which a horizontal section (30h) of the plastics layer rests under pressure in a sealing manner. A central region (11) of the closure cover passes with an adjoining, circumferentially oriented transition zone (11a, 11b, 11c) into an axially downwardly projecting skirt section (12) which ends in a roll-up region (21a, 21; 22). The plastics layer (30; 30h, 30v) is arranged on the inside of the cover in a manner adhering to the transition zone (11a, 11b, 11c) and the skirt section (12). An axial extent (h.sub.0) of the skirt section (12) and a radial dimension (b52) of the horizontally oriented end surface (52a) of the container neck (52) form a first ratio (v.sub.1) which is smaller than three.

A blow molded container is provided. The container includes a neck having a neck finish and a transverse rim that defines an opening. A closure is provided that is engageable with the neck such that the rim is movable relative to the neck to define one or more vents configured for passage of a gas. In some embodiments, methods of use and manufacturing containers are disclosed.

A sealed pharmaceutical container includes a shoulder, a neck extending from the shoulder, and a flange extending from the neck. The flange includes an inclined sealing surface defining an opening in the sealed pharmaceutical container. The sealed pharmaceutical container also includes a sealing assembly including a stopper extending over the sealing surface of the flange and a cap securing the stopper to the flange. The stopper has a glass transition temperature (T.sub.g) that is greater than or equal to −70° C. and less than or equal to −45° C. The sealing assembly maintains a helium leakage rate of the sealed pharmaceutical container of less than or equal to 1.4×10.sup.−6 cm.sup.3/s as the sealed pharmaceutical container is cooled to a temperature of less than or equal to −45° C.

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

Pressure relief blow out plugs for a container are disclosed as well as methods of using the same. One disclosed method involves providing a glass container that comprises a base and a body extending away from the base. The base includes a wall that defines a pressure relief passage. The method also involves inserting a pressure relief blow out into the pressure relief passage to seal the passage. The plug comprises a first inboard flange extending radially outwardly from the plug body, a stem, and a second inboard flange extending radially outwardly from the plug body and being spaced apart from the first inboard flange by a stem. The first inboard flange includes a first outboard sealing surface that provides an axial seal against the wall of the base of the glass container, and the second inboard flange including a circumferentially interrupted outboard facing retention portion the defines vent gaps.

An injection-molded preform for forming an 8 ounce PET container includes a neck portion configured to engage a closure and having a first wall thickness and an elongated body portion having an upper segment adjacent the neck portion and a lower segment adjacent an end cap. The upper segment has a second wall thickness substantially similar to the first wall thickness. The lower segment has a third wall thickness greater than the second wall thickness. The preform has a total weight less than 7 grams.

A method of making a bottle includes (a) forming a parison, (b) blowing the parison into a bottle of one-piece integrally formed construction, and (c) during the step (a) and/or the step (b), forming internal features on a neck of the bottle. Step (c) includes (c1) forming external features on the neck during the step (a), (c2) pushing the external features into the neck during step (b), and forming the internal features to be disposed entirely within the neck where the neck widens and at positions spaced from an internal surface of a neck finish and not extending into a shoulder of the bottle.

A polyester-resin-coated seamless can including a reduced diameter portion obtained by neck processing within a distance of 0% to 15% from a can body uppermost portion with respect to a total height of the can from the can body uppermost portion to a can bottom of the can. A ratio Im/Iu is 1.0 or more, where Iu (cps/μm) is calculated by dividing a maximum peak intensity in a range satisfying 15°≤2θ≤19° of an outer-surface coating in a maximum reduced diameter portion of the reduced diameter portion by a thickness of the coating at the measurement site, and Im (cps/μm) is calculated by dividing a maximum peak intensity in a range satisfying 15°≤2θ≤19° of outer-surface coating at a measurement site within a distance of 45% to 60% from the can body uppermost portion by a thickness of the outer-surface coating at the measurement site.

A container for a pressurized dispensing system. The container includes a plastic bottle and a base cup bonded to a rounded bottom of the plastic bottle with a hot melt adhesive. The base cup has a bottom surface that allows the container to stand upright. A method of forming the container is also provided wherein hot melt adhesive is deposited in a recessed region in a top wall of a pedestal of the base cup, and a center region of the rounded bottom of the plastic bottle is pressed against the hot melt adhesive such that the adhesive spreads out over the recessed region and the rest of the top wall of the pedestal. After the hot melt adhesive cools, the bottle is securely bonded to the base cup.

A blow molded bottle (1): a) which is self-collapsible during its emptying; b) which comprises at least two transversal grooves and/or ribs (6.1), preferably located in the tubular body portion (6), equipped with collapse starters (6.2); c) wherein the mean wall thickness (Tmean) of the tubular body portion (6) is—in an increasing order of preference—less than or equal to 200; 180; 160; 150 μm; preferably comprised between 65 and 150; and more preferably comprised between 90 and 130 μm. The invention also discloses a method, a preform (100) and a mold for the manufacture of the aforementioned container by blow molding. The invention also discloses a method for bottling liquid into the bottles (1), a method for dispensing the liquid, a dispenser for implementing the method and a method for packing the thin-walled bottles, in view of storage and transportation.
