Benefits of technology

[0008] A first aspect of the present invention provides a carton for packaging an article, for example a sachet, the carton comprising opposed top and base walls interconnected by first and second side walls so as to form a tubular structure. There further comprises an aperture struck from the top wall to receive a protruding portion of the article wherein the aperture extends into a panel adjacent the top wall so as to facilitate the folding of the top wall over the protruding portion during construction of the carton.
[0013] A second aspect of the present invention provides a blank for forming a wraparound carton for packaging an article such as a sachet for example, the blank comprising in series a first side wall panel, a base wall panel, a second side wall panel, a top wall panel and a securing flap, there further comprising an aperture struck from the top wall panel to receive a protruding portion of the carton in use wherein the aperture extends into a panel adjacent the top wall panel so as to facilitate the folding of the top wall panel over the protruding portion during the folding of the blank to form a carton.

Problems solved by technology

When flexible articles are to be packaged, such as sachets containing semi-liquid foodstuffs for example, alignment of the necks or caps of such sachets with apertures through which they protrude when erecting the carton may be problematic due to the tendency of such articles to deform and / or overlap with each other.

first embodiment

[0034] Referring to the invention as illustrated in FIGS. 1 to 5, and in particular to FIG. 1A, there is shown a first part 10A of a two-part blank formed from paperboard or like foldable sheet material for forming a wraparound carton and comprises a plurality of panels for forming the sides and ends of the carton. In this embodiment, additional panels are provided to secure the first and second blank parts together. Thus, in FIG. 1A there is shown a first end tab 12, first end wall panel 14, first side wall panel 16, second end wall panel 18 and second end tab 20 hingedly interconnected in series along fold lines 36, 38, 40 and 42 respectively. End flaps 24, 26, 28 and 30 are, in this embodiment, hingedly connected to the end edges of end wall panels 14 and 18 along fold lines 46, 48, 50 and 52 respectively. An inner base wall panel 22 is further preferably hingedly connected to one edge of first side panel 16 along fold line 44.

fifth embodiment

[0057] the invention as illustrated in FIGS. 11 and 12. In particular to FIG. 11, there is illustrated a blank 410 of paperboard or like foldable sheet material for forming a wraparound carton. There comprises a plurality of panels for forming a top wall, a base and opposed side walls. In this embodiment, the blank 410 comprises in series a base wall panel 414, first side wall panel 416, top wall panel 418 and second side wall panel 420 hingedly interconnected in series along fold lines 424, 426 and 428 respectively. Preferably, there further comprises an inner side wall panel or securing flap 412 hingedly connected to base wall panel 414 along fold line 420.

[0058] There may further comprise one or more aperture structures. In FIG. 11 there is shown a pair of aperture structures 430 and 432 are struck from base wall panel 414 and, in this embodiment, extends into securing flap 412. Each structure is substantially identical and therefore only aperture structure 30 is described in fur...

Abstract

A carton and a blank for forming a carton for packaging an article for example a sachet, the carton including opposed top and base walls interconnected by first and second side walls so as to form a tubular structure. An aperture is struck from the top wall so as to receive a protruding portion of the article wherein the aperture extends into a panel adjacent the top wall so as to facilitate the folding of the top wall over the protruding portion during construction of the carton.

Description

[0001] This is a continuation of international application No. PCT / US2003 / 007812, filed Mar. 14, 2003, which is hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] The present invention relates to a wraparound carton and blank. More particularly, the invention relates to a wraparound carton and blank for accommodating articles such as flexible sachets of semi-liquid foodstuffs, for example soft cheese, having a protruding sachet portion. [0003] Commonly, wraparound carriers are provided with apertures to retain one or more articles. U.S. Pat. No. 4,836,375 (Shuster) illustrates one example. [0004] Another example, U.S. Pat. No. 3,189,215 to Currie discloses a wraparound carton for packaging for bottles, slotted apertures being provided across the width of the top wall thereof to accommodate the necks of the two bottles. [0005] A further example, U.S. Pat. No. 1,782,429 to Johnson discloses a wraparound carton for packaging tubes of material, the carton having a tria...
