Pillow box blank

Abstract

A one-piece blank is provided which may be composed of paperboard, or other suitable material, and which is used to form a pillow-pack type of carton. The carton has a generally ellipsoidal shape with reinforced end walls, and it has a pair of cover flaps which extend over the elliptical edges of the end walls and which are glued together along one side edge of the carbon. The carton is shaped to have two spaced and parallel upright rectangular support pedestals at one end so that it may be placed in a self-standing position on a horizontal surface. Also, a hole may be provided in the rear wall of the carton at the other end, so that it may be hung from a wall or bracket. The product contained in the carton is exposed through a window formed in one of the cover flaps of the carton, the window having side flaps which serve to hold the product firmly within the carton to prevent it from rattling around in the carton.

Description

BACKGROUND OF THE INVENTION

It is usual in the fabrication of paperboard cartons of the pillow-pack type to provide a pair of cover flaps which are glued together along one edge and which define a carton having a generally elliptical cross-section, and to form end flaps which fold into the elliptical ends of the carton, and which may be opened to provide access into the interior of the carton. The pillow box blank of the present invention is appropriately shaped, slit and cut so that it may be formed into such a configuration.

In addition, however, the blank of the invention provides pedestals at one end of the carton so that the carton may be placed upright on one end on a supporting surface in a self-standing position. Moreover, a window is formed in one of the cover flaps, as mentioned above, so that the product contained in the carton may be displayed, the window having side flaps which serves to hold the product firmly in the carton.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT

As shown in FIG. 1, a one-piece blank is provided for forming an ellipsoidal-shaped pillow-pack carton. The blank has a first panel 10 and a second panel 12, each having arcuately-shaped ends, the panels being separated by a fold scoreline 14 which extends from one end of the panels 10, 12 to the other.

The panel 10 has arcuately-shaped scorelines 16 and 18 at each end thereof, and these scorelines each form an ellipse with the corresponding arcuately-shaped ends of the panel. The scorelines 16 and 18 form elliptical end panels 20 and 22.

The panel 12 has an arcuately-shaped scoreline 24 at its left-hand end which forms an ellipse with the corresponding end of the panel 12. The scoreline 24 and the left-hand end of the panel 12 form an elliptical-shaped end panel 26.

The panel 10 has slits therein adjacent the arcuate scoreline 16 which form a first rectangular-shaped pedestal for the carton; and the panel 12 has slits therein adjacent the scoreline 24 which form a second rectangular-shaped pedestal for the carton, the pedestals being designated 28 and 30 respectively.

The panel 10 also has a pair of longitudianl scorelines 34 and 36 therein and corresponding slots to form two flaps 38 and 40 which may be turned to provide a support for the product, and to permit the product to be revealed through the aperture formed by the flaps. The end panel 22 may have a hanging hole 42 therein.

The panel 12 has a further scoreline 44 extending adjacent its outer edge from one end to the other. The scoreline 44 defines a flap 46 which may be folded inwardly and glued on its reverse side to the outer edge of the cover flap 10.

Although the flaps 38 and 40 are shown in the panel 10 to form a window in that panel, the flaps may be formed in the panel 12, to form a window in the latter panel, if so desired.

As mentioned above, the representation of FIG. 2 shows the carton in a partially assembled form. FIG. 3 shows the completed carton without the product, and FIG. 4 shows the completed carton with a product supported therein and displayed through the opening in the front of the carton.

The invention provides, therefore, a blank which may be easily and quickly formed into a self-standing pillow-pack type of carton which also has the feature of supporting and revealing a product within the carton.

It will be appreciated that although one embodiment of the invention has been shown and described, modifications may be made. It is intended in the claims to cover the modifications which come within the spirit and scope of the invention.

Claims

What is claimed:

1. A one-piece blank for forming an ellipsoidal-shaped pillow-pack carton having a first panel and a second panel, each panel having arcuately-shaped ends, said panels being separated by a scoreline extending from one of their ends to the other, one of the panels having arcuately-shaped scorelines at the first and second ends thereof each forming an ellipse with the corresponding arcuately-shaped end, and the other of the panels having an arcuately-shaped scoreline at the first end thereof forming an ellipse with the corresponding arcuately-shaped end, and each of the panels having transversely spaced slits therein at the first end thereof interrupting and extending outwardly from the corresponding arcuately-shaped scoreline into the corresponding ellipse and interconnected therein to define spaced and parallel support pedestals for the carton when the arcuately-shaped ends are folded about the corresponding scorelines.

2. The one-piece blank defined in claim 1, in which one of the panels has slits and scorelines therein defining a pair of flaps which may be turned inwardly to support a product in the carton and to reveal an aperture in the panel through which the product may be exposed.

3. The one-piece blank defined in claim 1, in which the arcuately-shaped end at the second end of the other of said panels has a hole therein for hanging the carton.

4. The one-piece blank defined in claim 1, in which the other of the panels has a scoreline adjacent the outer edge thereof and extending from one end to the other to define a flap to be folded inwardly and glued to the outer edge of the first panel.

5. A one-piece blank for forming an ellipsoidal-shaped pillow-pack carton having a first panel and a second panel separated from one another by a scoreline extending from one end thereof to the other, said panels each having an arcuately-shaped scoreline at one end thereof defining elliptically-shaped end flaps for the carton, and each of the panels having transversely spaced slits at said one end thereof interrupting the scorelines and extending into the end flaps and interconnected therein to define support pedestals for the carton when the end flaps are folded about the corresponding scorelines.
