Definitions

  • U.S. Patent No. 4,883,631 issued to Ajmera, discloses a method for heat setting a molded plastic container.
  • liquid carbon dioxide or liquid nitrogen is vaporized at slightly greater than atmospheric pressure, and is used to flush the container following the step wherein the container is held against the mold. The flush continues for a time after the container is removed from the mold.
  • the stuffer rod construction contains a complex network of passages and orifices, and location of the cooling fluid orifices is critical to obtain uniform properties throughout the container.
  • the process is intended to reduce the total cycle time, the Ajmera process still has considerably longer cycle times than cold blowing methods.
  • the known heat setting processes have several drawbacks.
  • the first drawback is that the maximum practical hot filling temperature for the containers is about 90° C. Thus, the containers cannot be filled with boiling hot foods.
  • a second drawback is that the improved thermomechanical properties obtained by known heat setting methods largely disappear within 72 hours of heat setting the container. The container must therefore be filled soon after heat setting, or unacceptable shrinkage of the container will occur during filling, just as occurs with a cold blown container.
  • Yet another drawback is that conventional heat setting causes a substantial reduction in the container's ability to retain gases and moisture. The manufacturer is forced to choose between hot filling capability or good gas and moisture retention. Most beer is heat pasteurized before bottling, and requires a container that can be hot filled.
  • preform 11 is preheated in an oven (not shown) to soften it, according to methods known in the art.
  • the preform 11 is then grasped around the collar 23 by a collet 25 that has a pair of jaws adapted to hold the collar 23 snugly and to provide a surface on which bumper ring 21 can rest.
  • Collet 25 moves preform 11 to the next step, wherein preform 11 is placed into an opened split mold 26 made of two halves 27 and 29.
  • the mold halves 27 and 29 are then closed around preform 11.
  • the mold halves 27 and 29 are heated to a temperature preferably between 150° C and 177° C by oil circulating in channels 31 in the mold halves 27 and 29, or similar heating methods known in the art. Mold temperatures can be in the range of 130° C to 232° C; higher temperatures generally reduce the required time for heat setting.
  • a nitrogen supply valve 45 is opened at the same time or slightly after the high pressure air is supplied to the preform 11.
  • a check valve 46 in the nitrogen supply line 42 is set below the pressure of the high pressure air. This keeps nitrogen from flowing through the nitrogen supply line
  • check valve 46 is preferred, as it simplifies design (no need for additional timers, etc.) and prevents accidental backflow of air into the nitrogen line 42, but is not required.
  • the next step in the method begins when the vent valve
  • the nitrogen gas is created by vaporizing liquid nitrogen through a restriction (not shown) , located upstream of the supply valve 45. As the nitrogen passes through the restriction, it vaporizes completely, producing nitrogen gas under pressure and at cryogenic temperatures, typically between -209° C and -100° C. Nitrogen gas that has been cooled to a temperature below -50° C, and preferably to below -100° C, can also be used.
  • the gas supply line 42 should be suitably insulated, if necessary, to keep the nitrogen gas within the desired temperature range when it enters the molded preform 47.
  • the vent valve 43 is left open from the prior step, thereby depressurizing the final product 49 to atmospheric pressure before the stuffer 33 is removed.
  • the delay time between closing the nitrogen valve 45 and opening the mold 26 is critical. Cooling ceases when the nitrogen valve 45 closes.
  • the pressure holding the final product 49 against the mold 26 is also decreasing rapidly. Therefore, if the final product 49 is kept in contact with the mold 26 for longer than about 0.3 seconds, the container will overheat and shrink.
  • cooling of the mold 26 is often required to keep the final product 49 from sticking to the mold 26 during release. This is not necessary using the present method, because the cold nitrogen cools the final product 49 sufficiently to prevent sticking, even though the mold walls 27 and 29 remain heated.
  • the mold halves 27 and 29 can thus be kept at the heat setting temperature at all times, reducing thermal cycling fatigue on the mold 26 and greatly reducing the process cycle time.
  • Bottles made using known heat setting processes often suffer from stress cracking in the base, in and around the area where the stretch rod 35 contacts the preform 11.
  • the PET in this region crystallizes excessively due to excessive heating.
  • the excessive heat in turn occurs due to repeated heating of the stretch rod by conductive heat transfer from one cycle to another, followed by incomplete cooling of the stretch rod.
  • Stretch rod heat buildup and the associated stress cracking is avoided using the present method for two reasons. Firstly, the stretch rod heating time is greatly reduced from conventional methods, resulting in less heating of the stretch rod. Secondly, the nitrogen that cools the interior of the molded preform 47 also completely cools the stretch rod 35.
  • liquid nitrogen also results in fewer defects in the final product 49. Because liquid nitrogen contains no significant amounts of moisture, dirt particles, or oil, as compressed air often does, imperfections caused by these contaminants is prevented. As previously discussed, it is believed that the absence of water in the nitrogen supply is a factor in creating containers that retain their thermomechanical properties for longer than 72 hours.
  • a vent valve was opened, and vaporized nitrogen at about -200° C was blown into the molded preform.
  • the nitrogen was flushed through the container for 1.2 seconds, followed by a 0.2 second delay before opening the mold. Total time for the preform within the mold was less than 3 seconds.
  • control containers were prepared using a cold blow molding method.
  • the control containers were produced using identical preforms as those used to produce the test containers, and were molded to the same shape. Samples of both the control containers and the test containers were selected immediately after production, and tested for mechanical properties and hot filling performance at several temperatures. The hot filling performance tests were repeated on different samples 30 days after production.
  • Table 1 summarizes the results of the tests performed in the first 30 days after production.
  • the overfill volume data is adjusted to 68° F (20° C) .
  • test container was filled with hot oil at 230° F (110° C) .
  • the container's height reduction was less than one percent.
  • Hot filling performance did not markedly deteriorate after 30 days. In fact, tests showed a slight improvement in hot filling performance for 195° F (91° C) .
  • test containers The crystalline PET content of the test containers was lower than the content for known heat setting methods, which normally require about a 38% or higher crystalline PET content to ensure good hot fill performance. Despite the lower crystalline PET content, the test containers produced by the claimed method had improved hot filling performance over known methods.
  • the "preform" is a tubular length of plastic, such as polypropylene or polyethylene, that is extruded into the mold.
  • the plastic is extruded to the full length of the final product, and the open end of the preform is pinched shut by the bottom edge of the mold.
  • stretch rod 35 there is no stretch rod 35 or a step wherein the stretch rod 35 stretches the preform 11 to the length of the final product 49.
  • the preform is blown into the mold, first by a short pre-blow utilizing a low pressure air supply, followed by pressurizing the molded preform with a high pressure air supply.
  • the container is purged under a pressure of at least 520 kPag (75 psig) with cryogenic nitrogen, followed by depressurizing the container and releasing the final product from the mold.
  • This process can be employed to make extruded objects in shapes other than containers.
  • An advantage of the claimed method for extruded blow molding is that polyethylene containers produced using the claimed method will accept ink printing on the outer surface.
  • Extruded polyethylene containers produced by known methods require post-production treatment with an open flame on the outer surface of the container in order for ink to stick to the plastic's surface.

Abstract

On préchauffe une ébauche (11) en polyéthylène terephthalate (PET) possédant un corps cylindrique coiffé (13), une partie supérieure filetée et une collerette (19) afin de ramollir le PET. On place l'ébauche (11) dans un moule fendu (26) dont les parois sont chauffées pour atteindre une température située entre 150 °C et 177 °C. Une tige d'étirage (35), introduite à travers la partie supérieure de l'ébauche (11), étire cette dernière (11) axialement jusqu'à ce qu'elle atteigne la longueur du produit final (49). L'ébauche (11) est dilatée au moyen d'air ambiant comprimé et moulée contre les parois (27, 29) du moule (26). On évacue l'air et on injecte de l'azote sec à une température inférieure à -50 °C dans l'ébauche moulée (47) afin de la purger et de la refroidir, tout en maintenant une pression d'au moins 520 kPag. On maintient l'ébauche moulée (47) contre le moule (36) afin d'effectuer le recuit des surfaces intérieure et extérieure de ladite ébauche moulée (47). On interrompt l'apport d'azote et on ôte du moule (26) le produit fini (49).
