As a purchasing professional, one of the most important tasks is to ensure the quality of the products received from suppliers. When it comes to airless pump bottles, this is particularly crucial as they are commonly used to store sensitive products like cosmetics and pharmaceuticals.

In this article, I will provide a guide on how to inspect airless pump bottles to help ensure their quality and safety. By following these steps, you can better protect your customers and your brands. Let’s get started!

First: Initial Inspection of the Shipment

The first step in inspecting airless pump bottles is to conduct an initial inspection of the shipment.

● Checking the overall condition of the shipment

This involves checking the overall condition of the shipment, ensuring that the correct number of items are received, and documenting any issues found, like picture or video. It is important to carefully examine the packaging for any signs of damage or tampering. Check the outer box for any punctures, tears, or other damage that may have occurred during transit.

● Ensuring the correct number of items are received

Additionally, ensure that the correct number of items are received by counting the number of boxes and checking the packing list.

● Documenting any issues found

Any discrepancies should be documented and reported to the supplier immediately. By conducting a thorough initial inspection, you can ensure that the airless pump bottles have arrived in good condition and reduce the risk of any future quality issues.

Second: Counting and Sampling Airless Pump Bottle Parts

The next step in inspecting airless pump bottles is to count and sample the various parts. This involves counting the actual quantity of each part and selecting a sample using a certain standard, such as the Acceptable Quality Limit (AQL) sampling method.

● Counting the actual quantity of each part

It is important to count the actual quantity of each part to ensure that the correct number of airless pump bottle parts are received. This involves verifying the number of components, such as the bottle, pump, and cap, to ensure that they match the order specifications. Any discrepancies should be documented and reported to the supplier immediately.

● Selecting a sample using a certain standard (e.g., AQL sampling)

In addition to counting the parts, it is also necessary to select a sample using a certain standard, such as AQL sampling. This method involves randomly selecting a certain number of units from the total order to inspect for defects. The number of units to be inspected depends on the order size and the AQL level chosen. Common data as table below:

LOT Size General Inspection Level Sample Size Accept Point Reject Point
AQL 2.5 AQL 4.0 AQL 2.5 AQL 4.0 AQL 2.5 AQL 4.0
5000 – 10,000 200 200 10 14 11 15
10,001 – 35,000 315 315 14 21 15 22
35,001 – 150,000 500 315 21 21 22 22
150,001 – 500,000 500 315 21 21 22 22

For example, if the AQL level is set at 2.5 and the actual quantity is 10,000 units, the sample size would be determined by referring to an AQL table. The table might indicate that for an order size of 10,000 units and an AQL level of 2.5, a sample size of 200 units should be inspected. According the actual quantity and quality admitted with supplier, you can also get accurate data here.

The samples would be randomly selected from the total order, and each unit would be inspected for defects according to the quality standards agreed upon with the supplier. And the coming inspection procedure will be based on samples selected in this step.

Third: Inspection of Airless Pump Bottle Appearance

In this step, the inspector examines the physical appearance of the airless pump bottle to ensure that it meets the specified requirements. This includes checking the bottle body for any defects, such as cracks, scratches, or deformities, and examining the quality of any printing, hot stamping, electroplating, or other decorations.

● Examining the color, transparency, and any defects on the bottle body

The inspector should examine the color and transparency of the bottle body, as these are important factors that can affect the overall quality of the product. The color should be consistent and match the approved sample, while the transparency should be sufficient to allow the user to see the remaining product inside the bottle.

● Checking the quality of decorations.

When inspecting airless pump bottles, it’s important to check the quality of decorations, such as printing, hot stamping, or electroplating on the surface of the bottle. This involves examining the clarity, color, and consistency of the printing or stamping, as well as checking for any smudging, smearing, or misalignment. In the case of electroplating, the inspector should look for any areas where the plating appears thin or uneven, which could indicate a problem with the manufacturing process.

Overall, a thorough inspection of the airless pump bottle appearance is critical in ensuring that the product meets the specified requirements and is of high quality. Any defects found during this inspection should be documented and communicated to the supplier for resolution.

Forth: Functional Inspection of Airless Pump Bottles

In addition to visual inspection, it is important to perform functional tests to ensure that airless pump bottles are working as intended. Here are some tests to include in your quality inspection process:

1.  Leakage Test:

Fill the airless pump bottle with your cosmetic and check for any leaks or drips, normally using negative pressure test. This test ensures that the bottle is properly sealed and can prevent product contamination or spoilage.

2.  Pump Smoothness Test:

Press the pump multiple times to test its smoothness and ensure that it dispenses the product smoothly and consistently. This test is usually test by hand, press the pump, Soft and smooth to the touch, with a rebound speed synchronized with the hand, within 1.5 seconds.

3.  Output Test:

Measure the amount of product dispensed by the airless pump bottle to ensure that it meets the specified output volume. Output test rely on measuring the weight or volume of 10 – 20 times pumping, the result of dosage equals the weight or volume dividing times.

4.  Functionality Test:

Test the functionality of any additional features or mechanisms, such as twist-lock or snap-on caps, to ensure that they function as intended.

Performing these functional tests can help identify any issues with the airless pump bottles that may not be apparent during visual inspection. Document the results of each test in your quality inspection checklist to ensure consistency and accuracy in the inspection process.
