Embodiments of the present invention relate to a mouth piece for a bottle with a twist-off crown cap closure, wherein the mouth piece comprises a mouth piece body with a dispensing opening at the end; a closure thread for interaction with a twist-off crown cap in order to close off the dispensing opening so that it is liquid-tight, which closure thread comprises a plurality of thread protrusions arranged over regions of the circumference of the mouth piece body at a predeterminable thread pitch, protruding from the exterior side of the mouth piece body; a discontinuity running circumferentially around the mouth piece body, arranged between the dispensing opening and the closure thread and formed as a result of a tool during manufacture of the mouth piece in a transition region between two orifice jaws on the one hand, and a guide disc on the other hand; wherein an exterior end of the discontinuity is offset inwards relative to an exterior surface of the mouth piece body situated between axially adjacent thread protrusions. Likewise, embodiments of the present invention relate to a corresponding bottle, to a tool for producing a mouth piece for a bottle with a twist-off crown cap closure, and to a method for producing a mouth piece for a bottle with a twist-off crown cap closure.

Disclosed herein are methods and components for manufacturing substantially square glass containers and components and a method for forming parisons are disclosed. A plunger is extended into a mold which presses molten glass against the walls of the mold and against the extended plunger. Compressed air is applied through the neck of the parison to expand the parison outwardly against another mold and an end surface defined by a baffle. The neck ring provides retention features on the neck of the glass container and can include child-resistance features. Each of the molds, neck ring, and plunger produce substantially square glass containers having a substantially square neck.

A method of providing glass from a glass melting furnace to at least one mold, including providing an uninterrupted glass communication path from an outlet of the glass melting furnace to the at least one mold, and pressurizing the path at a location downstream of the outlet to move molten glass into the at least one mold. A related system, apparatus, and molding equipment are also disclosed.

A mould for production of glass bottles includes a body provided with an internal cavity first portion shaped according to the shape of the body of the glass bottle to be made. The bottom of the mould includes a first seat which is open both at the top, in communication with the internal cavity portion, and at the bottom. The mould further includes an adapter, which is also open at the top and bottom, which can be inserted in the first seat and provided at the bottom with a further shaped seat, which is intended for receiving a neck ring with relative finish thimble and plunger.

A process for producing glass bottles with shoulders includes a preform preparation step and a finishing step, in which a compressed gas is blown and the preform is rotated by 180 between the preform mold and the finishing mould. Preform preparation is achieved by introducing a glass gob into the mold through an upper aperture; inserting a blowing sleeve into the glass gob, the end of the sleeve extending beyond the shoulders of the outline of the preform of the bottle, the sleeve being closed by a plunger element slidable within its interior; opening the cavity of the sleeve to disengage the plunger element; and blowing air through the sleeve, wherein the final finishing step is achieved in an open preform mold, the volume of the cavity of the finishing mold being greater than the volume of the cavity of the preform mold by 5-20%.

This invention eliminates the need for a manual work of applying a mold release lubricant to blow molds and bottom molds by workers and reduces a burden on workers involved in the mold release lubricant application work while also increasing the safety of workers during mold release lubricant application, reducing downtime associated with the mold release lubricant application work, reducing changes in the mold release lubricant application locations and variations in amount of application for the blow molds, and, furthermore, contributing to a glass bottle quality stabilization. The application equipment (40) for applying the mold release lubricant is structured to apply the mold release lubricant to at least either a part of blow mold forming surfaces (31f) provided on the blow molds (31), or the entire surface of bottom mold forming surfaces (32f) provided on the bottom molds (32) located in the lower part of a finish molds (31), or both.
