Benefits of technology

[0025] In further embodiments, the bottle body is combined with other features such as a downwardly extending body having axially extending side panels fabricated from either a monolayer or multiple layers. The container is preferably in the form of a bottle having a drainback fitment. Advantageously, the bottle is more clear and has a higher gloss than a traditional liquid laundry bottle, but at the same time is functional as a heavy duty liquid detergent or other dispenser. With use of the metallocene polyethylene polymer / homopolymer high density polyethylene blend in accordance with the invention, the bottle may be significantly more transparent and have higher gloss without adversely affecting other properties.

Problems solved by technology

While these bottles are less opaque than those traditionally used, they remain to be cloudy.

example 1

[0072] Example 1 is a bottles having a monolayer structure that is made of a metallocene polyethylene polymer / homopolymer high density polyethylene blend. The metallocene polythylene polymer and homopolymer high density polythylene are both present in the blend at 50% by weight of the blend. The metallocene polyethylene polymer is Atofina Finacene BM359 SG. The homopolymer high density polyethylene used is Atofina Finathene BM961.

example 2

[0073] Example 2 is a bottle having a trilayer structure wherein the outer layer is made of a metallocene polyethylene polymer / homopolymer high density polyethylene blend. The metallocene polyethylene polymer / homopolymer high density polyethylene blend is the same 50 / 50 blend as used in Example 1. The various layers of the bottle are as illustrated in Table 1.

Abstract

The present invention relates to transparent or translucent bottles comprising a blend of metallocene polyethylene and a homopolymer high density polyethylene. The bottles may be either monolayer or multilayered. The bottle is surprisingly clear, has superior light transmittance in the visible light spectrum and has superior gloss.

Description

FIELD OF THE INVENTION [0001] The present invention relates to transparent or translucent bottles comprising a blend of metallocene polyethylene and a homopolymer high density polyethylene. BACKGROUND OF THE INVENTION [0002] One popular form of laundry detergent is the heavy duty laundry liquid. Its popularity is due in part to the convenience of the product form, in particular the ability to apply the detergent readily to soiled areas of the clothes. The popularity of laundry liquids has created a need for more convenient containers for dispensing these products. [0003] Laundry liquid detergents have traditionally been sold in opaque bottles. These bottles have been improved over time to incorporate measuring cups serving as closures, and fitments incorporating drainage mechanisms and pouring spouts. Bottles that are less opaque than those traditionally used have been placed on the market recently. While these bottles are less opaque than those traditionally used, they remain to be...
