Neck band using straight-tear film

Abstract

An improved neck band is provided for a container having a neck and removable closure at the end. The neck band is prepared from a straight-tear film, preferably a polypropylene film that has been oriented in a single direction. The neck band is provided with a tab and is attached to the neck and removable closure so that when the tab is pulled, the polymer material separates along a line around the circumference of the neck adjacent the skirt of the removable closure.

Description

I. FIELD OF THE INVENTION [0001] This invention relates to a neck band or label for a bottle or other container comprising a reservoir, a neck, and a removable cap at the end of the neck. The neck band encircles a portion of the cap and the neck of the bottle. II. BACKGROUND OF THE INVENTION [0002] Neck bands are frequently used on glass or plastic containers having an elongated “neck” with a closure at the end, such as, a screw cap. For example, neck bands are frequently used on “narrow neck” bottles for consumable products such as salad dressing, barbecue sauce, and alcoholic beverages and for containers of catsup and over-the-counter medicines. The bands contain graphics and information for marketing, product identification and other purposes, e.g., instructions, product expiration date, production lot data, etc. For marketing purposes it is highly desirable that high quality graphics can be imprinted or otherwise applied to the neck band and that the graphics and the band itself...

AI Technical Summary

Benefits of technology

"The patent describes an improved neck band for containers that can be easily opened and removed without leaving any evidence of tampering. The neck band is made from a special film that can be torn open along a line around the neck of the container. This film is made from a special polymer that is directionally oriented in a single direction. The neck band is applied to the neck and cap of the container, and a tab is placed on the neck band adjacent the skirt of the cap. When the tab is pulled, the polymer material separates along a line around the circumference of the neck. This process does not just separate the neck band, but removes a piece of neck band material around the container. The neck bands are easy to open, moisture proof, and can be manufactured and applied reliably and efficiently with standard, existing equipment."

Problems solved by technology

Thus, if opening occurs prior to use by the purchaser, the evidence of tampering is clearly apparent.
