The company is the maker of Vagisil brand feminine hygiene products and had been marketing Vagisil deodorant powder in a 7-oz bottle size. The company intended to come out with a solution to some powder leakage incidents that occurred in case of extrusion-molded high-density polyethylene container design.
Pharma Tech Industries had been blending and filling powder products for the company for around 15 years. PTI has been blowmolding bottles for other powder products for more than 25 years.
Richard Wade, a PTI molding/tooling engineer, has made four bottle designs that matched the company’s general concept and addressed the functional issues. The company has chosen one of them, and then a three-dimensional model was made, which resulted in a prototype and a custom mold.
The company claims that the new taller, tapered-waist containers are designed to provide a more distinctive, higher-profile appearance on the store shelf. After some changes made in the inside volume of the container to enable better settling of the powder and some fine tuning of the cap and seal, the new container which is injection blowmolded HDPE, 8-oz bottle was approved by Combe.
The whole process took about six months, and PTI went into full production with the new packaging in 2008. The company has a single source responsible for the bottle molding, powder blending, and container filling, capping, and labeling. PTI sources the two-piece sifter closures (inner piece is HDPE and outer portion is LDPE) from Rexam Plastic Packaging.
The pressure-sensitive, opaque polyolefin film labels are printed by Labelad. Front labels are flexo-printed in five colors, and back labels use one color. The labels are applied with Model 35PW in-line labeling equipment from Accraply, a Barry-Wehmiller company.
Packworld quoted Dan Beauleau, senior purchasing director of Combe, as saying: “We encountered certain functional issues during distribution and handling which we needed to resolve. These problems were due to an uncontrolled neck finish associated with extrusion molding.”
According to Mr Beauleau, the new PTI injection blowmold tooling provides a controlled neck finish that minimizes inadvertent powder leakage, while ensuring the sifter closure can be consistently engaged with ease. In addition, the new bottles provide several other important benefits.
