Definitions
- the present invention relates to a synthetic resin, particularly a polyethylene terephthalate resin (hereinafter simply referred to as “polyethylene terephthalate resin”).
- the present invention relates to a method for molding a pressure-resistant bottle and a cooling device.
- a large ⁇ ⁇ ⁇ ⁇ pressure-resistant bottle made of biaxial stretch blow molding such as 1.5 liters is composed of a conventional round-bottom bottle body and a base cup fitted to the bottom.
- bottles having a so-called big-foot-shaped betaroid-shaped bottom which is composed only of a bottle body having a self-supporting function, have come to be used.
- the bottom of the field body with self-supporting function has a complicated shape to be able to stand on its own and withstand internal pressure, but does not require a base force. Compared to the combination, it has the characteristics that it is superior in productivity and contributes to the problem of waste after use.
- the wall thickness distribution at the bottom of a 1.5-liter bottle is, as shown in FIG.
- the thickness distribution curve a the thickness is larger than the thickness of the legs 4 and the valleys 5 of the bottom 3, specifically, 2 mm or more. I have.
- the large thickness of the central part 6 of the bottom part 3 is a necessary thickness. If it is set thinner than this, the mechanical strength will be insufficient, and cracks will easily occur due to high temperature and high pressure after filling the content liquid. Become.
- the central portion 6 of the bottom portion 3 of this type of bottle 1 requires a relatively large wall thickness.
- the cooling rate of the blow mold to the predetermined temperature generally, the glass transition point temperature of the molding resin
- the blow time is shorter.
- the central portion 6 is easily deformed outwardly into a curved protruding shape after the mold release, as shown in FIG.
- the professional time was set to 4.0 seconds or more in order to cool the central portion 6 to a predetermined temperature by a blow mold.
- the temperature characteristic curve b in FIG. 5 shows the relationship between the blow time and the temperature at the bottom center part 6 and is a measurement result measured 7 seconds after the mold was released from the blow mold.
- a blow time of 4.0 seconds or more is required to reduce the temperature (glass dislocation point Tg) below the temperature at which deformation does not occur due to insufficient cooling at the bottom center 6. It can be seen that it is.
- Fig. 6 shows the change characteristics of the height H (see Fig. 8) from the bottom of the legs 4 of the bottom 3 to the center of the lower surface of the bottom 3 after blow-off for each blow time.
- a characteristic curve c 1 shows a characteristic with a blow time of 1 second
- a characteristic curve c 2 shows a characteristic with a blow time of 2 seconds
- a characteristic curve c 3 shows a characteristic with a blow time of 3 seconds
- a characteristic curve c 4 is the characteristic of professional time 4 seconds
- characteristic curve c 5 is the characteristic of blow time 5 seconds
- characteristic curve c 6 is the characteristic of blow time 7 seconds
- the height H is It has been known from experience so far that if it is kept above 4.0, it will be possible to prevent crazing (cracking) and cracking due to deformation, so that the blow time must be at least 4 seconds. I understand.
- Means to solve this dissatisfaction include increasing the cooling capacity of the blow mold or making the blow mold itself thin so that the cooling force acts strongly on the mold surface of the blow mold.
- the equipment cost increases significantly.
- the present invention has been made to solve the above-mentioned problems in the prior art, and it is an object of the present invention to significantly reduce the blow time of bottles.
- the purpose is to improve body productivity and obtain stable mechanical strength at the bottom. Disclosure of the invention
- Another means of the present invention includes:
- Another other means of the present invention comprises:
- the structural means of the present invention for implementing the above-described method means of the present invention include: A device that forcibly cools the bottom of a synthetic resin biaxially stretched pro-molded bottle having a big-foot-shaped betaloid-shaped bottom immediately after release.
- the mold Compared with the lower half of the bottom mold surface of the bottle blow mold device, the mold has a mold surface with the remaining portion being equal only by making the protruding height of the central part at most approximately equal to the maximum. Having a straightening jig with a cooling air spout in the center,
- the bottom of the center of the bottom of the bottle is blow-molded with a very short blow time of about 2 seconds. Deformation stops when the bottom height is 4 mm or more. Forced quenching of the bottom of this bottle was set so that the temperature at the center of the bottom was 70 ° C or less in 5.5 to 7.0 seconds, so the surface was generally released 25 to 30 seconds after demolding. The high temperature inside the bottom center (approximately 80 degrees according to actual measurements) will surely prevent the bottom center from being regenerated by heat, and the bottom will be completely cooled and hardened.
- the bottom height will be 4 mm or less before 15 seconds after release, and the bottom height will be 15 seconds after release. Decrease in height Deformation continues slightly. This means that the center of the bottom can be forcibly deformed by external molding force at the time of 15 seconds after release.
- the center of the bottom of the bottle after mold release can be deformed as desired by external molding force is limited to 15 seconds after mold release due to the effect of cooling by the atmosphere It turned out to be.
- the bottom of the bottle whose central part is bulging and deforming, is pressed against the straightening jig within 15 seconds while the bulging deformation is continuing, so that the center of the bottom is pressed. Due to the repulsive force from the correction type jig, the resin is pushed back up to a position substantially at the time of blow molding, that is, is corrected to a shape substantially at the time of blow molding at maximum.
- the degree of forced cooling to the bottom of the bottle may be such that the temperature at the center of the bottom is reduced to about 70 ° C. or less in as short a time as possible, and the cooling time is not limited to a certain value.
- the pressure resistance of the bottom of the bottle can be increased, but if the bottom height is increased with a blow mold, the stretching ratio to the tip of the leg increases, Inconvenience such as lowering of the shapeability of the bottle and voiding Occurs.
- the blow molding of the bottle by the blow mold was achieved while the shape of the bottom of the bottle by the blow mold was improved by setting the bottom height of the bottle slightly smaller.
- the center of the bottom is forcibly deformed by the remolding jig instead of the straightening jig until the bottom height is slightly larger than that at the time of blow molding, and the bottom is forcibly cooled in this state. To cool and harden.
- the bottom having an extremely complicated shape can be blow-molded with good shaping properties, and a sufficient bottom height can be obtained. Can be.
- the cooling process of the bottom of the bottle by the cooling device is as follows.
- the body released from the blow mold is immediately fitted with the bottom of this bottle into the mold surface and assembled into the straightening jig.
- the pressing jig is pressed against the portion with a predetermined constant pressing force. With this pressing, the central portion of the bottom is corrected and deformed by the correction type jig into a shape having a maximum bottom height during blow molding.
- cooling air was blown from the cooling nozzle to cool the upper surface of the bottom of the bottle and pressurize the bottle, and at the same time, it was opened in the center of the mold surface of the straightening jig. Cooling air is blown out from the spout to cool the bottom of the bottom of the bottle and cool and harden the center of the bottom. As a result, the shape of the center of the bottom is almost the same as that at the time of molding.
- the released bottle is assembled into the remolding jig and the pressing jig by the same operation, and the pressing jig is used.
- the center of the bottom is re-formed to a height higher than the height at the time of blow molding by the center of the mold surface of the re-forming jig. You.
- the shape of the bottom center portion has a larger bottom height than the shape at the time of blow molding.
