Three key points in the design of Health Products HDPE Plastic Bottle
Health Products HDPE Plastic Bottle to accept certain essentials in the design and principle of design, according to a certain point to carry on the design, has effective application to the design concept, guaranteeing performance advantages in application.
Health Products HDPE Plastic Bottle at the bottom of the majority to accept the bottom of the flat or convex double fillet layout situation, because the bottom of the convex bottle middle convex to the bottle, forming arch acupuncture point, can increase the body resistance to internal pressure ability, stability and guaranteeing the bottle factory. Can be restrained when injection molding plastic collapse and make bottle bottom thickness symmetry, and flat double rounded shape layout at the bottom of most Health Products HDPE Plastic Bottles for large volume, it is better to suffer from the pressure inside the bottle. The shape and size of the growth trend of the injection moulding and moulding of the small and medium Health Products HDPE Plastic Bottle neck of the plastic bottle neck of the shape of the original shape of the trapezoidal thread (single head) to the semicircular long thin thread growth.
This bottle of thread situation important is a good match each other with the bottle cap, because drug packaging is the performance depends largely on the bottle and the cap of the precision of the common, here is whether the reaction bottle sealed performance is good and bad important parts.
Most of the manufacturers have been able to find the sealing properties of the Health Products HDPE Plastic Bottle in the Health Products HDPE Plastic Bottles. From the profile of the bottle neck of the round Health Products HDPE Plastic Bottle neck and bottle neck, the neck and bottle shoulder are composed of two tangential circular radii, and the rotary body of the rotary table is taken from the cut point into two sections. The important factor that affects the strength of the bottle shoulder is the tilt Angle of the bottle shoulder. When the shoulder is too flat, the bottle is prone to 10. If the length of the bottle shoulder is 10mm, the Angle of the shoulder Angle should be greater than 15 degrees. The thickness of this part should not be less than 1mm (indicating the small bottle body).
Three main points:
The Health Products HDPE Plastic Bottle should be equipped with a rotating lid that can be adjusted to the size of the torsion. The torque can be drawn according to the diameter of the bottle cap. The size of the bottle and the mouth of the mouth is the important premise of the dampness and moisture resistance, and the precision is the key to prevent wet result.
In order to improve the safety of the medicine, the sealing of the sealing part of the bottle should be raised at first. The wall of the bottle is too thin to blow molding and the strength is low. It is usually required that the thickness of the rib and the threaded part of the bottle should be stronger than the thickness of the bottle, and the thickness of the other parts should be symmetrical. However, to improve the isolation and intensity of Health Products HDPE Plastic Bottles for health care products, the range of design value of bottle body thickness is 1.5 ~ 2mm, and the current thickness tends to grow thickly.
The air tightness of Health Products HDPE Plastic Bottle with health care products is important for the drug to be undampness and metamorphism during the effective term, and also to prevent the effects of light, heat and oxygen on drugs. Therefore, as a production enterprise of Health Products HDPE Plastic Bottle, we attach great importance to its air tightness detection. What is the health product Health Products HDPE Plastic Bottle air tightness? Simply in accordance with the relevant national standards for testing, such as detection of capsule health products of Health Products HDPE Plastic Bottle seal reliability is to take a certain number of capsule supplements HDPE bottles, in each bottle in a moderate amount of glass ball, tighten cap method. Then place it in a container with a suction device. Soak it in water. Vacuum to vacuum degree 27kpa. Maintain for 2 minutes. No water or bubble in the bottle. , of course, to ensure the tightness of supplemental Health Products HDPE Plastic Bottle capsules after index, also need some other economic indicators, such as sex, wet oxygen resistance and control, to ensure that the shelf life of the product quality.
Also has launched in the market now seal tester machine, using the principle of vacuum cleaner vacuum chamber, make health care products of Health Products HDPE Plastic Bottle submerged in the water sample in the production of internal and external pressure difference, look inside the sample gas to escape, to determine the sealing performance, or through the vacuum of the vacuum chamber, make sample production pressure difference inside and outside, to observe the inflation of the sample and release the samples after the vacuum in the shape of a recovery, in order to determine the sealing performance.
