Embodiment Construction

[0021] One specific embodiment of a container assembly 20 for forming a food container is in figure 1 and includes sleeve 22 and base 24. In general, the base 24 is configured to be attached to the bottom of the sleeve 22 to form an open top container for filling food. In some constructions, the container is for yogurt and the exemplary dimensions for sleeve 22 and base 24 described herein are for a container filled with 6 ounces (170 g) of flavored yogurt; however, it will be understood that the container The size and corresponding dimensions of the assembly components 22, 24 may vary from those described herein and still fall within the scope of the present disclosure. Similarly, other food types or forms can be accommodated by the container. After filling, the open top can then be closed by a thin sealing (eg, foil) member 26 that is removably adhered to the top of the sleeve 22 for sealing the food product inside the container.

[0022] The sleeve 22 includes or defines...

Abstract

An assembly for forming a container that contains food product and including a thermoformed sleeve and a base. The sleeve includes a frustoconical side wall, an upper lip, and a lower lip. The side wall defines an inner surface, an outer surface, and a plurality of circumferentially-spaced handling features including an outer surface indentation and a corresponding inner surface protrusion. The upper lip projects generally radially inwardly from an upper end of the sleeve and the lower lip projects generally radially outwardly from the lower end. The base is formed apart from the sleeve, and is assembleable to the lower end for closing off the lower opening. In some embodiments, each of the plurality of handling features are wedge-shaped. In yet other embodiments, the base is a thermoformed part, and is ultrasonically welded to the lower lip.

Description

technical field [0001] The present disclosure relates to plastic containers. More particularly, it relates to thermoformed containers for containing food products. Background technique [0002] One area where the use of plastic containers has expanded widely is in the food packaging industry. Thus, it is common for these plastic food containers to be used as terminal display packaging for food products sold to customers. Containers for dairy products such as cottage cheese, sour cream, etc. are typical of these containers, where the overall body of the container is provided with a larger diameter top opening that tapers down to a monolithic, lateral The side walls of the bottom wall, and the top opening are closed by a separate, plug-fit cover. Typically, the lid has a depending peripheral skirt that locks onto the upper rim of the tapered wall of the container body. [0003] A somewhat related current plastic food container design for flavored yogurt provides an inverte...
