Problems solved by technology

This installation process is troublesome, and requires a separate machine for installation.
The opening of the package is also not usually easy, and often requires the use of a tool such as a knife blade.
As a result, the process is relatively expensive, and could be somewhat dangerous to the consumer.

Embodiment Construction

[0015] In accordance with the invention, the device, generally Indicated by reference character 10 comprises broadly: a container element 11 and a lid or cover element 12.

[0016] The container element 11 may be of known type, commonly formed by injection molding or thermoforming. It includes a bottom wall 20, an arcuate side wall 21, an upper rim section 22, and a lid-engaging portion 23 forming upper and lower recesses 24 and 25. It also includes a radially-extending recess 26 supporting a horizontal portion 27 and a bead-forming portion 28 defining an annular recess 29 engaged by the lid element upon first installation.

[0017] The lid element 12, commonly formed as a thermoforming or injection molding operation, and includes a horizontal main wall 30, an inner rim member 31, a radially-extending wall 32 and an outer rim member 33. The rim member 33 includes a single or multiple lines of slitting 34, preferably formed using a Laser beam, and as seen in FIG. 3, include an outwardly-...

Abstract

A tamper-indicating wide-mouth food container including a thermoformed or injection molded lid having a downwardly-extending rim portion which engages the rim of the container, the rim portion separated by a tear strip along one or more slitted peripheral lines when the container is first opened. A slitting line extends downwardly from the peripheral line from the horizontal over a small area to form a manually-engageable tab which facilitates the tearing of the stilted peripheral line. When the tear strip is separated, that part of the rim portion below the tear strip falls free of engagement to provide an indication of a first opening of the container.

Description

[0001] Reference is made to our co pending application. Ser. No. 60 / 586,073 filed Jul. 8, 2004, to which a claim of priority is made.BACKGROUND OF THE INVENTION [0002] This invention relates generally to the field of wide-mouth food containers, In particular intended for the retail sale of such products as cottage cheese, margarine, and the like. Container and lid could be round or rectangular in shape. [0003] Attempts have been made in the prior art to provide a tamper-proof construction, or at least a tamper-indicating lid without the need of complex molding techniques. The most commonly used process is to shrink wrap in the area of the rim of the lid, overlying the mouth of the container. The shrink-wrapping must be broken before the lid can removed. This installation process is troublesome, and requires a separate machine for installation. The opening of the package is also not usually easy, and often requires the use of a tool such as a knife blade. As a result, the process is ...
