20080220114 | METHOD AND APPARATUS FOR CONDITIONING PREFORMS IN AN INJECTION STRETCH BLOW MOLD MACHINE - The conditioning station of an injection stretch blow mold machine is provided with a heater ring for each hot, soft preform presented to the station. The heater ring emits infrared light waves that are confined to the transition region of the preform between the neck and main body portions to pin-point the addition of heat to the transition region. | 09-11-2008 |
20090250427 | Viscous Product Bottle - A blown bottle constructed from synthetic resinous material is configured to facilitate the complete evacuation of viscous food product from the bottle using a conventional butter knife. | 10-08-2009 |
20120126462 | INJECTION BLOW MOLDING SYSTEM WITH ENHANCED PARISON TEMPERATURE CONTROL - An injection blow molding (IBM) system and method for consistently maintaining the surface temperature of the parison molds within a desired range. Implementation of this system/method can result in more consistent production of higher quality parisons and molded articles. Additionally, this system/method reduces the discretion required by the IBM operator and shifts the burden of consistently making high-quality parisons and molded articles onto the designer of the IBM tooling. | 05-24-2012 |
20120126463 | INJECTION BLOW MOLDING SYSTEM WITH ENHANCED PARISON BODY MOLD CONFIGURATION - An injection blow molding (IBM) system and method for forming a plurality of parisons and molded articles. The IBM system includes an injection station having two die sets and a plurality of first and second body mold halves each attached to a respective die set. Each of the first body mold halves has a corresponding second body mold half with which it cooperatively defines a cavity for forming the exterior shape of the body of one of the parisons. The individual, independent attachment of the body mold halves to the die sets allows easy individual replacement of faulty or worn molds. Further, such an attachment configuration also permits the body mold halves connected to a common die set to be spaced from one another, so as to reduce thermal expansion problems and ease dimensional tolerances required for the width of the body mold halves. | 05-24-2012 |
20120126464 | INJECTION BLOW MOLDING SYSTEM WITH ENHANCED PARISON NECK MOLD CONFIGURATION - An injection blow molding (IBM) system and method for forming a plurality of parisons and molded articles. The IBM system includes an injection station having two die sets, two body mold halves, and two neck mold halves. Each of the neck mold halves is attached directly to one of the die sets. The neck mold halves are configured to cooperatively form the exterior shape of the necks of one or more parisons. This type of neck mold attachment configuration can allow for better temperature control of the neck portion of the parison being molded therein. Further, such a neck mold configuration can reduce the cost of fabricating, installing, and/or replacing the neck molds. | 05-24-2012 |
20120126465 | INJECTION BLOW MOLDING SYSTEM WITH ENHANCED SUPPLY OF HEAT TRANSFER FLUID TO PARISON MOLDS - An injection blow molding (IBM) system and method for forming a plurality of parisons and molded articles. The IBM system includes an injection station having two die sets and two mold half assemblies. Each of the mold assemblies is attached to one of the die sets. The mold half assemblies are configured to cooperatively form the exterior shape of the necks of a plurality of parisons. Heat transfer channels formed in both the die sets and the mold half assemblies are fluidly connected with each other, such that a heat transfer fluid can be routed to the mold half assemblies via the die sets. | 05-24-2012 |
20120128812 | INJECTION BLOW MOLDING SYSTEM WITH ENHANCED HEAT TRANSFER CHANNEL CONFIGURATION - An injection blow molding (IBM) system and method for controlling the surface temperature of the parison molds by passing heat transfer fluid through a plurality of fluidly-coupled heat transfer channels. The heat transfer channels can be formed primarily in die sets to which the parison molds are attached. The placement and distribution of the heat transfer channels relative to the parison-forming surfaces helps control the temperatures of the bodies and necks of the parisons being formed, instead of relying on various adjustments by an IBM operator. This system/method reduces the discretion required by the IBM operator and shifts the burden of consistently making high-quality parisons and molded articles onto the designer of the IBM tooling. | 05-24-2012 |
20140042673 | INJECTION BLOW MOLDING SYSTEM WITH ENHANCED PARISON MOLD CONFIGURATION - An injection blow molding (IBM) system and method for forming a plurality of parisons and molded articles. The IBM system includes an injection station having upper and lower die sets and a plurality of upper and lower mold half blocks each attached to a respective die set. Each of the upper mold half blocks has a corresponding lower mold half block with which it cooperatively defines one or more cavities for forming the exterior shape of the body of one or more of the parisons. The individual, independent attachment of the mold half blocks to the die sets allows easy individual replacement of faulty or worn mold blocks. Further, such an independent attachment configuration also permits the mold half blocks of each die set to be spaced from one another, so as to reduce thermal expansion problems and ease dimensional tolerances required for the width of the mold half blocks. | 02-13-2014 |
