Abstract

Articles of manufacture, products, and packaging methods are provided that include collapsible container. Collapsible containers provided herein can define an open interior space with a peripheral side wall having a top edge and a bottom edge and a bottom wall attached to the bottom edge of the side wall. The bottom wall can include a displaceable portion in an expanded configuration that extends below the bottom edge of the side wall and adapted to being displaced to a collapsed configuration that extends above the bottom edge of the side wall. Product constituents (e.g., pouches of smokeless tobacco) can be placed in a collapsible container provided herein while the collapsible container is in its expanded configuration. After installing a lid onto a collapsible container to enclose the product within the collapsible container, the container can be collapsed to its collapsed configuration.

First claim

What is claimed is:

1. A method of packaging a consumer product, the method comprising:
depositing a product into a collapsible container, the collapsible container including,
a peripheral side wall having a top edge and a bottom edge, and
a bottom wall attached to the bottom edge of the peripheral side wall, the bottom wall including a displaceable portion, the displaceable portion including a conical side wall defining a truncated cone shape, the bottom wall having a variable wall thickness defining a concave exterior surface and including a thinner wall portion at a center of the bottom wall and a thicker wall portion disposed outward of the thinner wall portion, the thicker wall portion surrounding the thinner wall portion and the thicker wall portion extending along an outer periphery of the bottom wall, the bottom wall being disposed in an expanded configuration in which the bottom wall extends below the bottom edge of the peripheral side wall;

applying a force to the concave exterior surface of the displaceable portion, the applying causing the displaceable portion to mechanically buckle and thereafter be disposed in a collapsed configuration in which the bottom wall extends above the bottom edge of the peripheral side wall;
engaging a lid with a top peripheral region of the peripheral side wall, the lid retaining the product within the collapsible container, and the engaging being performed prior to the applying a force;
applying a label to the collapsible container so as to cover at least a portion of the lid and at least a portion of the collapsible container with the label, the label hermetically sealing the collapsible container and the lid, the applying a label occurring prior to the applying a force; and
screwing the lid onto the collapsible container, the lid and the collapsible container being coupled via a screw fit.
