This disclosure provides new containers, preforms, methods, and designs for small and light-weight carbonated beverage packaging that provide surprisingly improved carbonation retention and greater shelf life, while still achieving light weight. This disclosure is particularly drawn to small PET containers for carbonated beverages, for example less than or about 400 mL, and methods and designs for their fabrication that attain unexpectedly good carbonation retention and shelf life.

A method of forming a container and filling the container with a product. The method includes heat-set blow molding the container from a preform and hot-filling the container with the product such that the product occupies about 95% or more of a total interior volume of the container. A headspace volume is defined between a top fill line of the product and a brim of the container. The headspace volume is less than about 5% of the total interior volume of the container. The container is capped and allowed to cool. The container is configured to shrink during cooling such that the total interior volume decreases by about 0.5% to 1.5% during cooling. A base of the container is displaced after hot-filling and capping to reduce the total interior volume by less than about an additional 0.5% to 4%. The hot-filling, capping, cooling, and displacing of the base creates a pressure change within the container.

The present invention relates to a bottle neck, comprising a peripheral wall and an aperture that is delimited inside a top edge of the peripheral wall. The bottle neck also includes at least one outer thread located around the peripheral wall, the outer thread having a top end, and an offset located under the top edge and lateraly extending from the peripheral wall to a border of the top edge. The bottle neck comprises at least one slope located along the offset and over the outer thread, and the at least one slop extends from the peripheral wall to the border of the top edge in an outward inclined way.

A mold for molding an integral pulp-molded bottle shell includes a pulp suction system, an extrusion system, and a hot-press molding system. A process for producing the pulp-molded bottle shell by the mold includes: forming a wet bottle preform in a pulp suction cavity through the pulp suction system; controlling the moisture content and thickness of the wet bottle preform by extrusion of an elastomer bag of the extrusion system; and injecting a pressurized fluid through an elastomer bag in the hot-press molding system, and performing hot-press drying in conjunction with a lower hot-press mold. An apparatus and process for producing a pulp-molded bottle having a plastic liner are provided. The apparatus includes an area for molding a pulp-molded bottle shell, an area for cutting the pulp-molded bottle shell, an area for storing a plastic bottle preform, and an area for performing loading of a liner.

Container systems that include where the label is in the form of a sleeve, preferably a shrink sleeve. Consumer products that include such container systems. Arrays of consumer products, where some of the container systems include labels in the form of sleeves, and others include labels that are not in the form of sleeves. Methods of making such consumer products.

To provide a method for producing a multilayered container, which has a layer containing a polyester resin as a main component and a layer containing a polyamide resin as a main component and in which delamination is less likely to occur. The method for producing a multilayered container contains biaxially stretching and blow molding a preform having a polyester resin layer and a polyamide resin layer; a storage elastic modulus G′ of the polyamide resin being 5 MPa or more and less than 100 MPa; a moisture content of the polyamide resin layer being 0.5% or less; and the polyamide resin containing a xylylenediamine-based polyamide resin, 70 mol % or more of the structural units derived from diamine being derived from meta-xylylenediamine, from 80 to 97 mol % of the structural units derived from dicarboxylic acid being derived from an am-straight chain aliphatic dicarboxylic acid having from 4 to 8 carbons and from 20 to 3 mol % being derived from aromatic dicarboxylic acid.

A one-piece polymeric closure includes first and second closure portions. The first closure portion includes a first polymeric top wall portion and a first polymeric annular skirt portion. The first annular skirt includes a first set of splines on an inner surface thereof and knurls formed on an exterior surface thereof. The second closure portion includes a second polymeric top wall portion with a pull ring and a second polymeric annular skirt portion The second annular skirt portion includes a second set of splines on an outer surface thereof, an internal thread formation, and a locking ratchet band. The first and second sets of splines are configured to interact with each other when the polymeric closure is in a closed position. The polymeric closure opens by flipping the first closure portion with respect to the second closure portion via a hinge.

A drink container and related methods are disclosed hereon. A method of making a drink container includes (a) providing a beverage bottle for holding a beverage for human consumption; (b) forming a threaded mouth in the beverage bottle, the threaded mouth meeting government safety standards for drink containers; (c) providing a removable cap; (d) forming a threaded recess in the removable cap, the threaded recess meeting government safety standards for caps for drink containers, the removable cap further having a sprayer and a dip tube; and (f) threading the removable cap onto the beverage bottle and causing the dip tube to extend into the beverage bottle.

A container has an improved releasable cap, the container including a neck having external threads. The cap includes: a circular top piece for sealing the container; two sidewall sections connected to the top piece each having an internal threaded portion for engaging the neck of the container. Each sidewall section has two circumferential ends each spaced from an adjacent circumferential end of the other sidewall section such that two diametrically opposed expandable gaps are defined between the spaced circumferential ends. Two tabs each span a respective one of the two gaps, the tabs bulging outward from the sidewall section. The tabs are configured to be pressed inward thereby causing the sidewall sections to flex outward to disengage the internal threaded portions thereof from the external threads of the neck of the container permitting the cap to be removed therefrom.

The present disclosure is related to jars and containers and, more particularly, to the manufacture of readily recyclable jars and containers. An exemplary jar is comprised of an aluminum base and a first aluminum inner cup provided with a first cavity defined with the aluminum base. An outer thread is provided about an exterior surface of the aluminum base, and an aluminum lid with a second aluminum inner cup is provided within a second cavity defined within the aluminum lid. An inner thread mateable with the outer thread is provided about an interior surface of the second aluminum inner cup. A method of manufacturing readily recyclable jars can comprise providing a primary metal material and optionally applying a precoating to the primary metal material. The primary metal material may be formed into a jar with mating threads and a lid with mating threads. The primary metal material may optionally be finished. A liner may optionally be inserted. The lid and jar are then assembled, and a plastic cup may optionally be installed.
