A container includes an outlet defining an opening that is in fluid communication with an interior portion of the container, the outlet having a central axis. The container also a neck portion having an upper structural ring lying in a first plane that is substantially perpendicular to the central axis, and a lower structural ring lying in a second plane that is substantially perpendicular to the central axis, wherein the first plane and the second plane being separated by a vertical distance. The neck portion may have a gusset extending between the upper structural ring and the lower structural ring, and the gusset may have a plane of symmetry, wherein the central axis lies in the plane of symmetry. The container further includes a shoulder beneath the neck portion, a waist section beneath the shoulder, and a base beneath the waist section.

In a container spout portion included in a container body and configured to be sealed as a seal portion comes into contact with an inner circumferential face in association of attachment thereto of a cap having the seal portion therein, an arcuate portion convex inwards is formed between a top face and the inner circumferential face of the container spout portion. A tangential line to the arcuate portion starts from either a joining point between the arcuate portion and the top face or from a crossing point between a virtual extension line of the arcuate portion and the top face or a virtual extension line of the top face. An angle θ formed between the top face and the tangential line ranges from 30 to 60 degrees.

The present invention discloses a tethered stopper affixed to a bottle neck finish. The stopper includes a closure shell, a tamper band, and a strip connecting the closure shell to the tamper band at the perimeter of both the closure shell and the tamper band. The bottle neck finish includes a transport ring having a retaining feature configured to receive and retain the strip of the stopper when the closure shell is removed from the bottle neck finish. Also discloses is a method for securing the tethered stopper within the tamper band.

A container having a center portion and two side portions each situated at an angle to the center portion and extending in opposite directions such that the a left half of the container is substantially identical to a right half of the container. The container includes recesses and protrusions which enable the container to stack in two orientations generally perpendicular to each other.

Disclosed are preforms which incorporate improvements in the region of the neck and upper segment of the body to allow the production of lightweight containers, such as bottles suitable for containing water or other beverages. In accordance with certain embodiments, the improvements include a thinner neck finish area than conventional bottles, where the thinner area is extended into the upper segment of the body portion below the support ring. Reducing the thickness in these areas of the bottle allows for less resin to be used in forming the preform and bottle.

A pressure relief blow-out plug includes a body including an inboard end and an outboard end, and an inboard flange extending radially outwardly from the inboard end of the body. A package includes a container including a wall having interior and exterior surfaces, and a pressure relief passage extending along a longitudinal passage axis and having a circumferential passage surface extending through the wall between the interior and exterior surfaces, wherein the pressure relief blow-out plug is carried in the pressure relief passage.

Disclosed is a bottle for containing liquid content including a body portion, at least part or the entire portion of an upper portion of which is provided with a plurality of guides which protrudes inward from an inside surface thereof and is in a spiral pattern so that the liquid content can be guided towards an opening of a neck portion of the bottle while spirally revolving inside the bottle.

Preform assembly for blow moulding a container, comprising at least a first and a second perform, wherein the first perform is positioned inside the second perform before blow moulding the performs into the container, wherein each perform has a body forming portion having a wall thickness of less than about 8 millimetres, preferably less than about 6 mm.

First, a composite preform 70 including a preform 10a and a plastic member 40a in close contact with the outer surface of the preform 10a is made by preparing the preform 10a made of plastic material and arranging the plastic member 40a to surround the outer surface of the preform 10a. Subsequently, the composite preform 70 is heated and inserted in a blow molding die 50 and undergoes blow molding in the blow molding die 50, by which the preform 10a and the plastic member 40a of the composite preform 70 are inflated integrally and a composite container 10A is obtained.

A glass container is provided having a glass tube with a first end and a second end and a glass bottom closing the second end. The glass tube has a longitudinal axis and has, in a direction from the first to the second end, a top region, a junction region, a neck region, a shoulder region, and a body region. The top region is at the first end and has an outer diameter (d.sub.t), the neck region has an outer diameter (d.sub.n) with d.sub.n<d.sub.t, the body region extends to the second end and has an outer diameter (d.sub.b) with d.sub.b>d.sub.t, and the glass tube in the body region has a thickness (l.sub.b). The outer contour in a transition area between the top and neck regions is defined by a radius of curvature. The glass containers have a neck squeeze test load of at least 1100 N.
