FIELD OF THE INVENTION
The present invention pertains to the field of glass vessel making, and more specifically to the field of making a glass vessel having a sculptural interior.
BACKGROUND OF THE INVENTION
The prior art has put forth several designs for making glass vessels. Among these are:
U.S. Pat. No. 8,333,287 to Michael J. Lonsway, et al, describes a method of making a bottle having a neck with internal embossments. The bottle produced thereby is a longneck glass or metal bottle of one-piece integrally formed construction having a body with a closed based and a shoulder at an end of the body remote from the base, and a neck extending from the shoulder along an axis and terminating in a neck finish for attachment of a closure. The bottle neck includes at least one internal embossment for affecting the flow of liquids from the body through the neck.
European Patent Application EP 1894899 to Yves Brocheton describes glass articles and a process for making the same wherein the novel glass articles produced thereby comprise a soda-lime glass part and a borosilicate glass part fused to the soda-lime glass part wherein the glass can be colored by the addition of various chemical compositions to the borosilicate glass for creating colored glass articles such as high-end perfume bottles.
European Patent Specification EP 0598981 to Manabu Nakagawa et al describes methods and apparatus for manufacturing glass bottles comprising a Hot End coating process for treating the surface of the glass before annealing.

DETAILED DESCRIPTION OF THE INVENTION
The present invention teaches a method for making a bottle having a sculptural interior by using an inflatable textile core having a predetermined shape. Material suitable for use as the inflatable textile core includes, but is not limited to high temperature textiles, such as carbon fiber, ceramic, alumina, mullite, silica, or any other suitable material, woven, knitted, crocheted, felted, sewn, assembled or otherwise configured. FIG. 1 shows a woven, or crocheted form of high temperature yarn, of z or s spun thread, to create a textile core 12 or bladder, inflated in the initial inverted position of the blow and blow, commercial glass bottle production technique. The gob or gobs 14 is pressed around the inflated fiber core 12 to create an internal form 16 capable of being specific and very different from the external form. With or without the inversion of the bottle, and second blow of the parison, the mold can be heated, blown, and or vacuum suctioned to fully fill the glass around the core for the neck, and full side fill of the mold.
An embodiment comprises the use of a computer woven, knitted or crocheted form bladder creating the parison, or internal void or bladder having a specific predetermined sculptural shape. This bladder 12 is herein referred to also as the textile core, or knitted inflatable core. This radically differentiates this bottle making technique from the results obtainable from any other historic blow and blow fabricated bottle technique.
Essentially, any blow and blow bottle either has an interior matching the exterior, or has an air formed bubble, or roundish shape brought about by various injections of air. In contrast, the “sculpted” inflatable core 12 of the present invention wherein the gob 14 is drawn around the form, the interior shape exists separate from any restraints of the exterior form. Heretofore, this effect could only be obtained in unique art technique castings, or machined, laser, or chemical forming of the interior.
FIG. 4 shows a representative sampling of shapes suitable for the textile core. Although shapes shown include initials, a cloud shape, and a bird shape, it is contemplated that any shape is suitable for use in this invention including shapes from nature such as flowers, birds, trees, leaves, tree bark, fish, frogs, reptiles, mammals, insects or any other contiguous shape. Suitable shapes also include geometric or architectural forms.
The novelty of using an inflated textile core 12 of a specific sculptural form allows for virtually any imaginable form to exist within the bottle. This is particularly desirable for luxury mass produced perfume bottles. It is contemplated that the textile core can be used for multiple bottles.
Surfacing of the core can alter the surface of the woven core from its natural texture, and, or allow for mineral coloring agents to melt into the glass gob.
The bladder or textile core 12 to be used in the present method can be used in conjunction with CAD, computerized knitting, crocheting, and several blow and blow techniques. The bladder 12 can be attached to the air injection port through a custom connection of the textile to the mold by any suitable means, such as by use of a clamp, fixated fitting, retaining system or tapered nozzle 20, for example. Compressed air can be applied from the top, as shown in FIG. 2, pressing the gob around the core 12. The core 12 is inflated by compressed air applied from the bottom, as shown in FIG. 3. The nozzle 20 or air entry port serves to form the neck of the bottle.
The ability to collapse the inflatable fabric core 12 allows for a clean evacuation of the core 12 through the mouth of the bottle. It is contemplated that the fabric core 12 can be reused for more than one bottle. This is the key to allowing both the unique and independent form, and also in allowing for a one piece bottle that requires only a stopper or mist dispenser.
The method of the present invention applies to an I.S. machine which transforms a gob into a glass bottle, well known by the person of ordinary skill in the art of glass bottle making.
Prior to, or simultaneously with or subsequently to the injection of a gob into the bottle mold, the fiber inflatable core 12 is inflated. The blow of the gob 14 pushes the molten glass around the core 12. This is shown in FIG. 2.
FIG. 3 shows a secondary blow of compressed air completing the form 14 surrounding the core 12. Inversion may or may not be used depending on the form of both the core shape, and external bottle shape.
Pulling the glass completely to the sides of the mold 18 may be done with vacuum voiding of the mold or additional pressure in the initial inverted position. This method can be used in conjunction with multi gob entry, a secondary heating, and or blowing of the gob, and or drawing a vacuum on the mold to complete the fill, and stabilize the inflated core. In an embodiment, one or more glass rods (not shown) positioned in the main mold body can be used along with multi gob entry to stabilize the inflatable fabric core 12. These rods are of a dimension and glass similarity such that they can melt into the body of molten glass in such time as it takes to stabilize the body of molten glass around the inflated core. This glass stabilizing rod dimension varies according to the bottle size, thickness, and blow temperature of the gob.
The inflation of the fabric core remains constant until the bottle is formed. After cooling sufficiently, the deflated fabric core 12 can be withdrawn through the neck of the bottle for re-use. The inflation for interior core, and withdrawal of all core material to form the parison, or bottle's interior form is distinctive from what is possible from just the injection of air, and is a novel feature of the present invention.
While abundant additional opportunities for texture, surfacing, and coloration are possible, they all hinge on the concept of an inflatable fabric core in forming the void, or parison within the bottle.
In an embodiment, the present invention includes clamps for gathering, and holding in position of the fabric core, variations of heating, gob insertion, and blowing of the gob, and, or position of the bottle in forming, or equipment used in annealing and finishing of the bottle.
Use of inflatable fabric sculptural cores have not previously been used in industrial blow and blow glass bottle mass production. The inflatable fabric core can be reusable.
Although this invention has been described with respect to specific embodiments, it is not intended to be limited thereto and various modifications which will become apparent to the person of ordinary skill in the art are intended to fall within the spirit and scope of the invention as described herein taken in conjunction with the accompanying drawings and the appended claims.
