Case Study: From Glass Roller Bottles Dealer Issues to Stable Factory Supply

Glass roller bottles dealer issues led a Spanish oil factory to us for leak-proof custom roller bottles with precise fit, stable quality, and bulk supply.

The issues of the glass roller bottles dealers compelled to invite a glass-rollers-bottles manufacturing factory in Valencia, Spain, to collaborate closely with Vesseluxe, a professional glass roller bottles factory, to have a guarantee of customization and sale of bulk production.

Client Background

The factory manufactures blended raw essential oils to both skincare and aromatherapy brands in Southern Europe. They discussed with Vesseluxe to make glass roller bottles with an amber glass body, smooth roll-on stainless steel ball and matte black ribbed cap with inner leak-proof insert.

The glass was ambered to ensure the oils that were sensitive to light were kept safe whereas the ribbed cap was included to enhance the grip needed when using it frequently in cosmetic processes. The choice of Vesseluxe was influenced by the fact that we provided immediate factory control of materials, constant roller-ball fitting accuracy and customization without having to order too many at once.

Challenges

Sourcing leakage and roller-ball poor fit: The client had to deal with batches in which roller balls are either too loose or tight when using a glass roller bottles dealer. Free floating balls resulted to leakage of oil in transportation and too tight fittings resulted to failure to apply it freely- product returns and wastage of filling time.
Sluggish reaction and lack of specifications in production: The dealer was just a middleman and could not verify the exact neck tolerances, the thickness of glasses and materials to use as an insert. This led to duplication of sampling processes, delays in launching and the fact that it was not clear whether bulk orders would correspond to approved sample.

Cause Analysis

Our group checked the faulty samples and found the root cause, the irregularity in controlling the neck-dimension and the mismatch of the roller-ball components tolerances supplied by various subcontractors.
Our solution was to check measurements uniformly, ensure that bottle necks and roller assemblies were compatible, and centralize the sourcing of components to one controlled production process.

Solution

Installed full-mold tolerance control in order to maintain uniform neck sizing.
Pre-assembly compatibility testing of matched roller balls, inserts and caps.
Leak testing of filled sample unites prior to bulk shipment.
Delegated a special project coordinator to give proper technical drawings and checks at every phase.

Result

The designed roller bottles were shipped with fitted roller, smooth rolling and no leakages during filling and transportation. The client minimized the packaging complaints, increased the filling process rate, and ensured that there would be a follow-up bulk order of more oil blends within the quarter.
