Definitions

• Carton blanks constructed of a series of connected foldable panels are available for consumer assembly of a carton.
• Prior art constructions are typically made with one blank for producing the body portion of the carton and a separate blank for producing the lid.
• Manufacture of separate blanks for the body and lid portions of the carton requires two separate manufacturing processes with the inherent labor costs. With the current separate body and lid components, custom width liner specifications are necessary for the manufacturing of the corrugated sheets, typically used to form the carton blanks.
• carton blanks received from the manufacturer are seldom the exact amount ordered of each blank. Specifications usually call for a specified quantity plus 5% and minus 0%. The mismatch of body and lid components resulting from a variance in ordered quantities is frequently encountered.
• the prior art does disclose a foldable blank for constructing a carton using an insertable divider or partition, formed as a detachable part of the blank. See, for example, U.S. patent 4,396,115. Nevertheless, the prior art fails to disclose or teach a unitary carton blank comprised of a body portion and a lid portion detachably connected to the body portion and further configured for printing, folding and packaging as a compact single unit.
• the unitary carton blank is constructed with the body and lid portions of the blank removably connected to each other in a single manufacturing operation.
• the single blank structure allows the body and the lid to be die-cut, printed, glued and packaged as one unit, thus reducing manufacturing time and thereby increasing output production.
• the ability to produce more product in the same amount of time creates opportunities to decreased finished goods inventory.
• Due to the construction of the carton blank of the present invention standardized raw liner specifications for the corrugated supplier are possible.
• the standard size minimizes the supplier's exposure to raw materials and maximizes the supplier's production capacity. Elimination of the separate lid reduces material handling and receiving, administration, and system requirements for maintaining inventory records for separate body and lid blanks.
• the body portion of the blank can be folded into a collapsed carton blank with the lid overlying and fully contained within the parameters of the body portion of the blank. This provides a neat unit readily adapted for packaging in groups of stacked blanks.
• the body and lid portions of the blank are configured whereby the lid is provided with double edge panels for reinforcing the single wall panels of the body of the erected carton.
• Fig. 1 is a plan view of the carton blank of the present invention
• Fig. 2 is a plan view of a double blank assembly in accordance with the invention, as shown in Fig. 1;
• Fig. 3 is a plan view, partially broken away to show overlapping panel sections, of the folded collapsed carton blank of Fig. 1;
• Fig. 4 is a plan view of a modified embodiment of the carton blank of the invention
• Fig. 5 is a plan view, partially broken away to show overlapping panel sections, of the folded collapsed carton blank of Fig. 4.
• the carton blank of the present invention is constructed of corrugated fiberboard.
• the blank 1 is shown in Fig. 1 as comprised of a plurality of panel sections foldably connected together.
• a first plurality of panel sections defines the body 2 of the carton blank and a second plurality of panel sections defines the lid 3 of the carton blank.
• the body includes a bottom panel section defined by two bottom panels 4 and 5, a pair of side panel sections defined by two side panels 6 and 7, and a pair of end panel sections defined by four end panels 8, 9, 10 and 11.
• the side panel 6 also includes a flap panel 6'.
• the lid on the other hand, includes a top panel section, defined by the single top panel 12, a pair of side edge panel sections, defined by a left side edge panel 13 and a right side edge panel 14, and a pair of end edge panel sections, defined by the end edge panels 15, 16, 17 and 18.
• the die cutting and scoring equipment used for producing the carton blank originally forms two carton blanks of identical shape and dimensions. This structure is cut horizontally along the line 19 to form two identical carton blanks, constructed as shown in Fig. 1.
• each of the panels of the carton blank includes a top edge, a bottom edge, a left side edge and a right side edge.
• the side panel 6 has the left edge of the end panel 8 foldably connected to its right side edge.
• the bottom edge of the bottom panel 4 is foldably connected to the top edge of the side panel 6.
• the end panel 8 has the left side edge of the other side panel 7 foldably connected to its right side edge.
• the other side panel 7 has its top edge foldably connected to the bottom edge of the bottom panel 5 and the left side edge of a second end panel 9 foldably connected to its right side edge.
• the bottom panel 5 has a third end panel 10 foldably connected to its left side edge and a fourth end panel 11 foldably to its right side edge.
• the bottom edge of each of these end panels 10 and 11 are removably connected to the top edge of the end panels 8 and 9, respectively. This connection is by way of perforations and is broken by the consumer when assembling the carton, as is well known.
• the lid 3 is removably connected to the right side edge of the end panel 9. This connection is also by perforations so that the lid 3 can be removed from the body 2 to permit separate assembly of the body and the lid into their final carton configuration.
• the lid 3 has its side edge panel 13 connected to the right side edge of the end panel 9.
• This side edge panel 13 and the opposite edge panel 14 each include the conventional end tabs 13 ' , 14 ' which are folded toward each other and interlocked with the end edge panels 15, 16 and 17, 18 during assembly of the lid, as is customary.
• the lid and body have the same dimension as measured from a straight line drawn through the bottom edge of any of the side and end panels 6-9 to a straight line drawn through the top edge of any of the bottom and end panels 4, 5, 10 and 11. Also, for reasons explained below, the dimension of the lid as measured across the top panel 12 and two side edge panels 13 , 14 is slightly less than the width of either of the side panels 6 and 7, as measured from their left side edge to their right side edge.
• the blank has an overall height of 22 3/16 inches, with the panel 6 having a height of 10 inches and the panel 4 a height of 12 3/16. Also, the panels have the following width dimensions:
• Fig. 3 shows the carton blank in a folded collapsed state. This is the state in which the blank is packaged in a stack with a number of other blanks and the state in which the customer receives the blank.
• the panels 4 and 6 of the blank have been folded 180° along a first fold line extending along the left side edge of the end panel 8, to a position underneath the remaining panels of the body 2.
• the blank is also folded 180° along a second fold line extending along the right side edge of the other side panel 7 to bring the end panel 9 into overlapping relationship with the flap panel 6 ' .
• This overlapping relationship is along the right side edge of the end panel 9.
• the flap 6' is secured to the right side edge of the end panel 9.
• the folded collapsed body of the panel defines a predetermined surface area by way of the panels 5, 7, 8 and 10.
• the lid overlies the body and fits within this surface area.
• the upper left hand corner of the figure has been broken away to show the location of the lid 3 and its containment within the surface area of the body panels. This is accomplished by having the distance between the left side edge of the end panel 9 of the body 2 and the right side edge of the right side edge panel 14 of the lid slightly less than the distance between the first and second fold lines.
• the containment of the lid is further facilitated by having the dimension of a lid, as measured across the top panel 10 and the two side edge panels 13 and 14 slightly less than the width of the side panel 6.
• the body as assembled, will have a double bottom, comprised of the bottom panels 4 and 5, and double end walls 8, 10 and 9, 11.
• the assembled lid is adapted to be placed over the open end of the body with the top panel 12 over the open end and the side edge panels 13 and 14 engaging the side panels 6 and 7 of the body and the double end edge panels 15, 16 and 17, 18 of the lid engaging with the double end panels 8, 10, 9, 11 of the body.
• Figs. 4 and 5 show an alternative embodiment of the present invention.
• the same reference numbers followed by the prime sign are used for designating the same panels as in the embodiment of Figs. 1-3.
• the lid and the body are dimensioned whereby the double walled end edge panels 15 ' , 16 ' and 17 ' , 18 ' , when placed over the open end of the assembled body will engage with the side panels 6 ' , 7 ' . This, in turn, will reinforce the top edges of these side panels which are of single thickness.
