Description

United States Patent O 3,406,814 DISPLAY CARTONS Richard F. Gulliver, St. Paul, Minn., assignor to Waldorf Paper Products Company, St. Paul, Minn., a corporation of Minnesota Filed Oct. 22, 1965, Ser. No. 500,529 Claims. (Cl. 20G-45.14)

ABSTRACT OF THE DISCLOSURE This invention is in conjunction with a carton including a rectangular display panel having side and end walls hinged to the edges thereof and pairs of gusset flaps connecting adjoining edges of the side and end walls at the corners of the display panel. A bottom panel is hinged to one side wall and is anchored to the opposite side wall to form a tubular structure. The invention lies in securing av sheet ofshrink film to the'edges of the side and end Walls most remote from the display panel. When the carton is erected into `tubular form, the shrink film is held in U-shaped form throughout its length so that the product This invention relates to an improvement in display cartons and deals particularly with a carton capable of holding an article in fixed relation upon the interior surface of a wall `of the carton.

An object of the present invention resides in the provision of a carton having a sheet of shrink film secured thereto which normally is supported in surface contact with the panels which it overlies. As a result, the contents of the carton may be inserted in the usual manner, and the carton closed on conventional equipment. However, when heat is applied to the closed carton, the film will shrink toward a wall of the carton, holding the contents snugly against this wall.

A feature of the present invention resides in the provision of a carton including a tubular wall structure, the top panel of which may be apertured to provide a display panel. The display panel is hingedly connected to side and end walls, and the adjoining edges of the side and end walls are connected by pairs of diagonally folded gusset flaps. A sheet of shrink film is marginally attached lto the lower edges of the side and end walls, and also to the lower edges of the gusset iiaps. The article is inserted on the bottom panel, or on the panel opposite the display panel. After the carton has been closed, heat is applied and the film is shrunk. As the film is connected only along the lower edges of the walls, the article is held firmly against the lower carton panel.

A further feature of the present invention lies in the provision of a tubular carton having end closures which may be folded into carton closing position. Shrink film is attached to these closures along 4the edge thereof most remote from the hinged edge. As a result, when the film has been shrunk about the object or contents of the carton, the tension of the film tends to hold the closures in closed position.

These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims.

In the drawings forming a part of the specification:

FIGURE 1 is a perspective view of the finished carton or package.

FIGURE 2 is a sectional view through the carton on a ice plane parallel to the display panel, the position of the section being indicated by the line 2 2 of FIGURE 3.

FIGURE 3 is a sectional view through the carton on a plane at right angles to that of FIGURE 2, the position of the section being indicated by the line 3 3 of FIG- URE 2.

FIGURE 4 is a sectional view similar to FIGURE 3 but showing the carton before it has been filled.

FIGURE 5 is a diagrammatic view of the paperboard -blank from which the carton is formed.

FIGURE 6 discloses the blank of FIGURE 5 with the stretch film attached thereto.

FIGURE 7 is a perspective view of the carton in tubular form before it is filled and closed.

In the following description, the panel which usually forms the display panel is usually uppermost during the carton filling operation, and, accordingly, will be indicated as either the display panel or the top panel. Once the carton has been filled, the display panel may form a vertical panel for display purposes, as indicated in FIG- URE l of the drawings.

With reference first to FIGURE 5 of the drawings, the carton A is shown as including a display panel 10 which is foldably connected along parallel fold lines 11 and 12 to side walls 13 and 14, respectively. A bottom or base panel 15 is hingedly connected to the side wall 13 along `a fold line 16. A glue flap 17 is hingedly connected to the side wall 14 along a fold line 19. The walls described may be secured in tubular form by adhering the glue flap 17 to the bottom panel 15 in overlapping relation thereto.

End walls 20 are hingedly connected to opposite ends of the top Wall 10 along parallel fold lines 21 which intersect the previously described fold lines at right angles. Tuck flaps 22 are foldably connected to the ends of the end wall panels 20 along parallel fold lines 23.

In order that the shrink film may be attached to the carton blank about its entire periphery, the side and end walls of the carton are connected by diagonally folded gusset panels. Generally triangular gusset flaps 24 are connected to the end walls 20 along the extensions of the 1 fold line 11. Substantially triangular gusset flaps 25 are foldably connected to opposite ends of the side Wall 13 along extensions of the fold line 21. Each gusset flap 24 is connected to an adjacent gusset flap 25 along a diagonal fold line 26 which emanates from a juncture between the fold line 11 and a fold line 21.

In a similar manner, substantially triangular gusset aps 27 are foldably connected to the end Walls 20 along extensions of the fold line 12 and similar gusset fiaps 29 are foldably connected to the end edges of the side wall 14 along extensions of the fold lines 21. Diagonal fold lines 30 connect each gusset flap 27 to an adjoining gusset liap 29.

If desired, each pair of gusset flaps 24, 25, and 27, 29 may occupy a rectangular area. However, to reduce the space within the carton occupied by the gusset flaps, the combined pairs of gusset flaps may be cut olf diagonally as indicated at 31 and 32, resulting in a generally octagonal body portion in the particular form of construction illustrated.

While the blank A is in its fiat form, a sheet or shrink film B is applied to the surface thereof. The shrink film B is attached along areas of adhesive 33 to the edges of the side wall panels 13 and 14 most remote from the display panel 10. The film is also connected to the end wall panels 20 along areas of adhesive 34 which eX- tend along the edges of the panels 20 most remote from the display panel 10. The shrink film B is also connected to the edges of the gusset panels 24, 25 and 27, 29 which are most remote from the display panel 10, these areas of adhesive being indicated by the numerals 35 and 36. Thus, the shrink lm B is connected about its entire periphery to the paperboard'bla'nk A and is otherwise unattached to the blank. The shrink ilm overlies virtually the entire surface of the blank with the exception of the `bottom panel 15 and glue ap 17.

When the carton is to be used, the blank may be squared up as indicated in FIGURE 7, the shrink lm remaining substantially in contact with the surfaces of the blank which it overlies. FIGURE 4 of the drawings shows the blank in tubular |form with one of the end enclosures in closed position. The article C is inserted into an open end of the carton and the end closures 20 swung downwardly, the gusset iiaps folding substantially into face contact with one another inwardly of the carton. The tuck aps 22 are inserted into the carton to overlie the bottom panel 15.

` Heat is then lapplied to the carton to the extent necessary to shrink the lm. Due to the fact that the lm is adhered to the lower edges of the side and end walls,

the shrinking of the film B draws the object C against the bottom wall 15, holding the article snugly in place. The display panel 10 is usually provided with one or more apertures such as 37 forming window openings through which the object may be viewed. The shrink film B is usually transparent in form, and the object or articles may be seen through this film.

In accordance with the patent statutes, I have described the principles of construction and operation of my improvement in display cartons; while I have endeavored to set forth the best embodiment thereof, I desired to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
