Problems solved by technology

While a score line can be configured to improve structural integrity by limiting the degree of weakening of the score line, limiting the degree of weakening of the score line generally makes it more difficult to tear the carton along the score line

Embodiment Construction

[0024] described herein and Figures 1 to 5 The exemplary carton depicted in employs lines of weakness (eg, perforation lines) configured to facilitate the double-opening properties of the gable-top carton while still maintaining sufficient carton structural integrity. The user can open the top of the tray, such as image 3 painted, or, alternatively or in addition, remove the top portion of the carton, as Figure 4painted. One or more lines of weakness may optionally be used in conjunction with the top opening feature, and patterns of weakening lines may optionally be used in conjunction with the top removal feature. Improved structural integrity of the carton, especially under compressive loads, can be achieved by varying the cut and spine lengths of the perforations, scoring patterns, or other such lines of weakness at various locations around the carton Average ratios (e.g., cut / ridge ratio), strategic placement of cut and spine segments based on carton geometry, provis...

Abstract

A dual-opening carton has a front, rear, and opposing side panels. A flap extends over the top of the carton, allowing the top to be opened and re-closed. A score line extends around the carton to facilitate the removal of a top portion of the carton. The score line has segments extending along the front panel, the rear panel, and rear portions of the side panels that have a relatively low cut length to land length ratios that maintain relatively high structural integrity. The score line also has segments extending along the front of the side panels have a relatively high cut length to land length ratio to facilitate tear propagation. The score line extending along the side panels is angled so that a pull force vector removing the top portion of the carton runs along a plane generally parallel to the score line.

Description

technical field [0001] This article describes a gable top carton, in particular a gable top carton with a double opening feature. Background technique [0002] Gable top cartons are used to package consumer goods. A gable top carton generally has a rectangular bottom, and two opposing gable panels coupled together at the top of the package. Some gable top cartons are openable at this top, such as disclosed in US Patent No. 2,333,123. For example, some packages can be opened by separating a portion of one of the gable panels, such as disclosed in US Patent No. 7,891,543. After separating the gables, the contents of the package can be removed or dispensed through the opening. Some gable top cartons are configured to allow the entire top of the carton to be partially removed, such as disclosed in US Patent Publication 2010 / 0078467. [0003] Cartons having both a top opening and a removable top portion may allow the user to select a preferred method of opening the carton. D...
