Benefits of technology

[0015] Another object of the invention is the provision of a container having a reclosable pour spout that provides superior sealing characteristics.

Problems solved by technology

The rising popularity of blanks capable of forming containers having integral pour spouts has created a problem for manufacturers.
Unfortunately, the requirement of mediums other than paperboard increases the costs of production for manufacturers.
Moreover, the requirement for integrating additional mediums into a paperboard blank to form a pour spout creates numerous problems for manufacturers that incorporate in-line processes.
The modification of existing equipment is time consuming and expensive.
Known containers fail to provide a sift-proof seal, thus permitting the articles (e.g., dry baby cereal) in the container to spill out of the container at the sealed ends.

Abstract

A packaging blank capable of forming a reclosable container comprises in one embodiment a front panel having opposing side panels, a rear panel connected to the front panel by the second side panel, a top panel connected to a top edge of the front panel, a bottom panel connected to a bottom edge of the front panel, and a pour spout flap connected to a top edge of the second side panel. Upon construction the packaging blank provides a reclosable container having an integral pour spout that is releasably securable to a portion of the top panel. Still further, the invention relates to a method of forming the container and a method of packaging articles in the container.

Description

FIELD OF THE INVENTION [0001] The invention relates to a packaging blank. In particular, the invention relates to a packaging blank for use in automated processes that is capable of forming a reclosable container having an integral pour spout that is reclosable. The invention further relates to a reclosable container formed from the blank having a tab lock that releasably engages an integral pour spout. Still further, the invention relates to a method of forming from the blank a container having enhanced sealing qualities. BACKGROUND OF THE INVENTION [0002] As known to those skilled in the art, packaging is typically formed from packaging blanks, or blanks for short. It will be understood that as used herein the term “blank” may include cardboard, rigid paper, flexible plastic, or similar products made of paperboard or plastic. In particular, the packaging industry favors the use of one-piece flexible blanks, which are readily incorporated into automated processes for forming contai...
