Benefits of technology

[0007] A unique sealing and opening arrangement has now been discovered for use with a plastic molded food container. Specifically, the invention comprises a molded plastic food container body or cup, open at the top, that is especially useful for holding sauces, condiments, spices and the like. The invention also comprises a top

Problems solved by technology

In fact, it is a disadvantage.
For example, soy sauce and similar containers in common use today in the take-out food industry are often sealed so tightly that a user must use two hands to force open the lid, and the force is often large enough to spill out the contents of the container prematurely.

Embodiment Construction

[0021] In a preferred embodiment, and as best seen in FIGS. 2 and 5, the invention comprises a molded plastic cup or other hollow container body 10, comprising a base 30, side walls 40, a side rim 52, a top rim 54, an inner rim 56, a ledge 58 and a lower tab 110, formed in a one-piece construction and having an open top. The container body is particularly useful for holding relatively small or light quantities of foods or liquids such as sauces, creams, dips, condiments, spices and the like.

[0022] In a feature of the invention, base 30 is preferably polygonal in shape. In this embodiment, the base forms an octagon when viewed from below, although any other polygonal shape may be used. The side walls 40 are flat near the base, are also arranged polygonally around the edges of the base, and meet along rigid edges 50. Near the top of the body, the side walls assume a smooth cylindrical shape, and the open top of the body is preferably circular or oval in shape when viewed from above. ...

Abstract

A plastic food container has a body and a removable lid. In a closed position, the lid forms a watertight seal to contain food or liquids. The lid is easily removed in a “pop-open” fashion using two fingers of one hand to squeeze outwardly-protruding tabs. Upon squeezing, the tabs operate as levers to open the lid.

Description

FIELD OF THE INVENTION [0001] This invention relates to containers and, more particularly, to food containers which are made from molded plastic and include a pop-open lid for easy opening. BACKGROUND OF THE INVENTION [0002] Food containers commonly used by restaurants and food packaging companies typically have a container body with side walls having a top rim and a lid having a bottom rim. The two are adapted to mate along their respective rims to form a watertight seal. They are commonly made in a simple molding process from plastic and, although reusable by the customer, are generally not returned to the restaurant. [0003] Preferably, these containers must be reusable or resealable so that leftovers can be stored in the same container. The seal must be flexible enough to allow for easy opening and closing, yet tight enough to provide a secure seal against either leakage of food from the container or introduction of air and microbes into the container to prevent spoiling. Thus, t...
