For blow molding manufacturers, ensuring plastic containers are free from defects is critical for maintaining package integrity and brand reputation.
This is especially true for angle neck plastic containers, commonly used for household, industrial and automotive products like toilet bowl cleaners, automotive fluids, and cleaning solutions. These containers, designed for easy pouring and application in tight spaces, present unique challenges when it comes to leak testing.
To address this, see the ALPS Inspection BottleStop™ Multi-Head Leak Tester, a new, streamlined system engineered for angle neck, choked neck-prone, and large, stable containers.
Keep reading to learn more about defect challenges for angle neck containers and discover how the ALPS BottleStop delivers accurate, cost-effective testing to protect your products.
Angle neck containers are typically made from high-density polyethylene (HDPE) due to its durability and chemical resistance. These containers are widely used for:
The angled design allows users to dispense liquid into hard-to-reach areas, but it also complicates the inspection process due to the irregular shape and potential for choked neck defects.
Check out our leak testing fundamental guides.
One of the most common quality issues with angle neck containers is choked neck defects, where the neck becomes partially blocked during the blow molding process. This can lead to:
These defects not only compromise product performance but also pose a threat to brand reputation. Detecting a choked neck defect can be challenging, requiring the use of a fixed or sensing choked neck probe to thoroughly inspect the container's neck.

Traditional equipment often struggles with angle neck designs due to:
To overcome these obstacles, leak detection systems must combine adaptable testing probes, secure container handling, and regulated container spacing to ensure every container meets quality standards. This is where the BottleStop design steps in.
Need help identifying a plastic container defect? Our feasibility testing can help.
BottleStop simplifies leak testing for angle neck, choked neck-prone, and large, stable containers with these key capabilities:
This streamlined multi-head system integrates with your existing conveyor or an optional ALPS-supplied conveyor. Programmable sensors track containers as they move through the gate, test stations, and reject zones, while gate cylinders manage flow and stop cylinders or hold tooling to ensure precise positioning.
Any defective angle neck containers are automatically removed by an integrated reject cylinder or an optional air jet for reliable, failsafe removal. This controlled process guarantees accurate results, minimizing waste and safeguarding your investment.
Leak testing angle neck containers doesn’t have to be a challenge. With BottleStop, you can achieve:
BottleStop also comes with a touchscreen HMI with remote connectivity and is backed by expert service and support from our full-time service technicians and engineers.
