Problems solved by technology

In the past, this in-house printing required the use of the more expensive and time-consuming two-sided printing method, printing on both surfaces of the cardboard blank from which the carton blank was cut.
In addition, since the inner surface of the general carton has no coating for printing, the printing quality and the marks that can be printed on the inner surface of the carton are limited.

Embodiment Construction

[0025] As noted above, depending on the format of the packaging process using the carton blanks, the carton blanks can be in the form of pre-glued, detached sleeves, or completely flat sheets. image 3 The carton blank shown is of the former form, which is typically partially folded and glued at the carton manufacturing site and delivered to the packaging machine in the form of a split sleeve. The packaging machine then erects the sleeve into an open-ended carton sleeve. The product is placed in the carton sleeve before it is sealed. Generally, this form of carton is mostly used in beer and soft drink bottling plants. on the other hand, Figure 8 The cartons shown are typically made from completely flat shipping carton blanks which are then folded around the product on a packaging machine and glued closed. The latter form of carton blank differs from the former form of carton blank in that the gluing of the cartons to form a sleeve is performed at the product manufacturing f...

Abstract

A method of making a reinforced carton includes the steps of advancing a carton blank along a path, and progressively laminating at least one strip of reinforcing material to the advancing carton blank. The strip of reinforcing material, which may also be paperboard, has a width less than the width of the paperboard blank and is applied with adhesive at selected locations across the width of the paperboard blank. The paperboard blank and laminated strips of reinforcing material are cut into pieces of predetermined size; the piece is then die cut and creased with fold lines to form the carton blank. Next, the carton blank is formed into a carton for articles, and the laminated reinforcing material is reinforced in selected portions of the carton. Multiple strips of reinforcing material and multiple layers of the strips may be laminated at selected locations on the carton blank to provide reinforcement in more than one portion of the carton.

Description

technical field [0001] The present invention relates generally to the packaging of articles; more particularly, to the manufacture of cartons capable of containing a variety of articles for shipping and sale. Background technique [0002] The packaging industry has long used cartons of various designs and constructions to package a wide variety of items such as canned and bottled beverages, food, detergents, and more. Typically, cartons are assembled or folded from cardboard blanks that are cut from long cardboard sheets that are gradually drawn from large rolls of cardboard, either by dies or by rotation. Fold lines are scored into the blank to form the various strips of the carton to aid in folding the blank into the final carton shape. In some cases, such as in beer and soft drink packaging, this paperboard blank is pre-applied with glue and sent to the packaging machine in the form of a substantially flat, disassembled sleeve; The sleeves are a...
