Packaging container and blank for producing the same

Abstract

A packaging container that is made from a flat sheet of material or extruded material with score lines that fold into a plurality of side panels, 3 or more, forming a tubular member having a longitudinal axis. The bottom folds concave and the top folds convex forming triangular webs having apexes which join at the longitudinal axis with the side edges of the adjacent triangular webs sealed together providing structural rigidity. The webs fold inside or outside and the scores can be such that a plurality of variations can be created for different appearances of the container. Protrusions extend outward from the apex of at least some of the top and bottom web panels which provide a means for sealing. Flaps on the ends of the side panels fold and seal together either to the inside or outside. The container can be stacked and nested.

Description

FIELD OF THE INVENTION [0001] The present invention relates to packaging containers formed from flat sheets of material or extruded materials that are provided with appropriate score lines to facilitate conversion of the packaging material into individual sealed packaging containers and to blanks or packaging material from which the packaging containers are formed. BACKGROUND OF THE INVENTION [0002] Consumer packages intended for single use and containing consumer products of various types including both dry goods and beverages are normally produced from packaging material comprising layers of paper, cardboard, plastic, foil or the like. When consumable food products are housed in the containers they are coated with a food grade material. Such materials may be laminated if desired to provide additional strength. The containers housing liquids also include liquid tight seals which are normally realized by heat sealing or appropriate adhesives. The prior art contains examples of vario...

AI Technical Summary

Benefits of technology

"The patent describes a container with flat side panels that are folded inward to create a tubular member with a longitudinal axis. The container has top and bottom closures made up of triangular-shaped panels that are connected to the flat side panels. When the triangles are folded inward, their apexes meet at the same point as the side edges of adjacent panels, and they are sealed together. The technical effect of this design is a container that can be easily folded up for easy storage and use, with strong and secure closures that can be sealed tightly."

Problems solved by technology

However, it has been found that the sealing of the top and bottom of such containers to obtain a liquid-tight seal is, in most instances, difficult.

Such foils are however very difficult to handle both by the merchant and by the user.

An additional problem which is encountered with all of the prior art type of packaging for such consumables is the difficulty in transporting the packages, and storing the packages, as well as stacking and shelf space limitations encountered as a result of the configuration of the package.
