Benefits of technology

[0008] The present invention is directed to a new design for a family of dispersion-based colorant containers to address the key issues and objectives above. The design consists of a container extrusion blow molded from HDPE (high density polyethylene). The new container incorporates a wide opening having a diameter of at least 50 mm that allows for a removable and replaceable screw top closure. The design has the following advantages over the current metal quart containers in the marketpla

Problems solved by technology

This method of opening the cans has exposed those employees who formulate the paint for the individual consumer to potential injury.
Additionally, both opening tools and methods of use leave small openings in the top of the can from which the colorant has to be poured.
This results in slow addition time to the dispensers, does not allow the metal containers to fully empty, and does not allow for access to properly clean the containers for environmentally sound disposa

EXAMPLE 1

[0028] In this example, the pouring speeds of colorant from plastic containers of this invention in quart and ½ gallon sizes were compared to that of the typically used quart metal cans.

[0029] Due to the larger opening than the two holes from a church key can opener pour times were reduced 65-75% (10-15 seconds) per container with the quart container of this invention. The larger opening allows additional material to be recovered using a rubber kitchen spatula. Wasted material is significantly reduced using the ½ gallon container when compared to two of the existing quart cans. Residual colorant was reduced by an...

Abstract

A plastic container used to hold a dispersion-based paint colorant and capable of dispensing the colorant into paint dispensing machines, comprising an open top capable of holding and securing a cap, and having a wide mouth with a diameter of at least 50 mm. The plastic container has a cylindrical body extending below the open top, and a plurality of vertical ribs spaced around the body to strengthen the container. The plastic container may be used to hold a dispersion-based paint colorant or personal care products such as shampoo and conditioner.

Description

[0001] This application claims priority to Provisional Applications U.S. 60 / 556,814, filed Mar. 27, 2004 and patent application Ser. No. 11 / 048,184 filed Feb. 1, 2005.FIELD OF THE INVENTION [0002] The present invention is directed to a novel container for the packaging of dispersion-based colorants to improve ease of use and efficiencies of preparing colorants for final dispensing in paint formulating centers. BACKGROUND OF THE INVENTION [0003] Currently, dispersion-based colorants, such as universal colorants, are packaged in quart metal cans. The metal cans require a variety of tools to be opened in order to fill colorant dispensers. Such colorant dispensers are used to provide one or more colorants to a base paint to provide a paint of a desired color. A common method used to open the metal cans of universal, dispersion-based colorant is with the use of a carpet knife and a “church key” type triangular can opener. This method of opening the cans has exposed those employees who fo...
