DETAILED DESCRIPTION OF THE INVENTION

[0042] One preferred embodiment of the inventive leak resistant cardboard box invention is shown in FIGS. 1 through 8. An alternative preferred embodiment of the box is shown in FIGS. 9 through 17. While the invention is described in connection with certain preferred embodiments, it is not intended that the present invention be so limited. On the contrary, it is intended to cover all alternatives, modifications, and equivalent arrangements as may be included within the spirit and scope of the invention as defined by the appended claims.

Definitions

[0043] As used herein the following abbreviations and terms are understood to have the meanings as set forth:

[0044] The term Hydogenated Triglyceride includes both animal fats and vegetable oils and is derived from one or more of them. Animal fats include beef tallow, pork lard, poultry grease and fish oils. Vegetable oils include palm oil, soybean oil, peanut oil, olive oil, coconut oil and cottonseed oil.

[0045] The term Paraffin is a wax-like product derived from petroleum.

[0046] The terms Paper and Paperboard includes substrates and surfaces of cellulosic material.

[0047] The term Food Boxes refers to corrugated cardboard boxes which are used to transport fluid carrying foods such as poultry, butchered meats, beef, pork, lamb, seafood and produce.

[0048] It has been found that hydrogenated triglycerides can be substituted for petroleum based paraffin waxes and wax compounds in the manufacture of paper products. All of these application systems involve melted hydrogenated triglycerides held at temperatures in the range from around 125 F. to 170 F. which is either squeezed, rolled, cascaded, sprayed, or doctored onto the linerboard, paper, carton stock, or corrugated medium surface to impregnate the same.

[0049] The method and machinery or equipment for repulping and recycling scrap paper in the paper and paperboard or liner board industry is both an established and well known art, and the equipment required is standard and commonly installed at most mills incorporating recycled paper in their manufacturing feed stocks. Thus, those skilled in the paper making art are also knowledgeable in re-pulping and recycling.

[0050] Food boxes are unique paper products that need to withstand water, poultry fluid, meat fluid, seafood fluid and produce fluid. The present inventive food box is made of double backed corrugated board having a corrugated medium of 30 to 40 lb./1000 sq. ft. (MSF) paperboard of an A, B, C, E and F flute size (weight depends upon various external factors).

[0051] A flat liner or backer board of Kraft paper (various grades) which has been impregnated with hydrogenated triglyceride and coated with a biodegradable water resistant plastic copolymer is glued to one side of an impregnated fluted medium with a starch based adhesive and a second flat liner or backer board of Kraft paper which has been impregnated with hydrogenated triglyceride and coated with a biodegradable water resistant plastic copolymer is adhered to the other side of the impregnated fluted medium with a starch based adhesive to form a backed corrugated board. The preferred flute size used in the Food Box invention is a C flute having 39+/3 flutes per lineal foot with a flute thickness of 5/32 inch. The Kraft paperboard liner may be bleached white, coated white (white coat), mottled white or colored. As is well known in the art, the medium paper is humidified by means of high pressure steam which softens the paper fibers to facilitate the formation of the flute and consequent gluing. After formation of the board, this humidity is removed by drying in the dry-end. In the present invention, the newly formed corrugated liner board is heated from the bottom by hot plates and the adhesive holding components of the structure is cured.

[0052] The inventive present repulpable degradable leak resistant food box 20 as shown in FIG. 1 is constructed with an inner coated Kraft paper liner or backer glued to a corrugated paper medium and an outer coated Kraft paper liner or backer glued to the medium. Both of the liners and medium are impregnated with hydrogenated triglyceride and the liners are coated with a styrene acrylic co-polymer. Hydrogenated triglycerides which can be used in the invention are animal fats and vegetable oils. Animal fats include beef tallow, pork lard, poultry grease and fish oils. Vegetable oils include soybean oil, peanut oil, olive oil, palm oil, coconut oil and cottonseed oil with the preferred oil being palm oil. Hydrogenated triglycerides used in the impregnation are commercially available from C.J. Robinson Co. and Chemol Corporation.

[0053] Both liners or backers are coated on their outside surfaces with a coating of a styrene acrylic co-polymer water based solution ranging from about 75% to about 95% by weight. The coating emulsion is heated and mixed at the general time of application and heated to a temperature from about 160 F. to about 180 F., preferably at about 170 F.

[0054] The coating (not shown) is a styrene acrylic co-polymer solution (% by weight of the styrene acrylic co-polymer ranging from about 50% to about 55% most preferably about 52%) and has a pH ranging from about 8-9 with fully cured Tg of +7, a specific gravity ranging from about 1.04 to about 1.6 and viscosity (cps) of about 400. The coating has a vapor density the same as water with 30 minute Cobb values ranging from about 25 to about 35. The coating thickness is 3 lbs. per thousand square feet (MSF) and is fast drying, recyclable, repulpable, printable and glueable.

[0055] The inventive corrugated food box 20 is shown assembled in FIGS. 1-5 and is constructed from a cut and scored cardboard sheet blank 22 as individually shown in FIG. 6 and in blank multiples shown in FIG. 7. The food box insert members 30 are constructed from a single piece cardboard blank 90 as shown in FIG. 8.

[0056] The box blank 22 is a unitary double backed cardboard sheet manufactured as previously discussed which is cut and scored in a box cutting station to form a bottom or base panel member 44 with foldable end members 46 which are folded upward perpendicular from the bottom planar base 44 along fold lines 48. Each end member 46 is formed with foldable tab member 50 on each side which is scored at a 45 angle leading from the end member base section 55 at the intersection of fold lines 48 and 62 to the midpoint of the end member 46 at the beginning of the end member top section 54. The tab member 50 has a fold line 51 running down its middle which intersects the tab member into two identical sections 52 and 53. Tab section 53 is connected to side panel end tab 66 and its function will be described in the side panel description. The end member 46 has a top section 54 extending vertically upward from planar surface of the base member 44 and has a linear top end edge 56 which is parallel to the surface of the base member 44.

[0057] Side panels 60 are integrally connected to the bottom member or base 44 and folded perpendicular to the base planar surface along fold lines 62. Each side panel 60 has a foldable tab section 53 which is scored at a 45 angle from the intersection of fold lines 48 and 62 and is folded together with tab section 52 along tab mid-fold line 51 inward into the box chamber to engage the end opposite tab section 52. Tab section 52 and tab section 53 together form a 90 angle on the blank.

[0058] The folding of end tab 66 of the side panel along fold line 48 and the side panel side panel 60 along fold line 62 positions the end tab 66 adjacent the top section surface 54 and directly over the linear top end edge 56 of end member 46. The end tab 66 forward edge 70 extends from its position adjacent the linear top end edge 56 upward so that the end tab linear top edge 73 is aligned with the top edge 93 of the center panel 92 of insert member 30 when the insert member 30 is glued to the interior of the box as seen in FIGS. 2 and 4. The tab upper forward edge 70 is cut away and beveled 72 to form a 45 angle with a line drawn from the top edge 73.

[0059] The insert member 30 for the box is shown in FIGS. 2-5 and multiple insert member blanks are shown in the single piece rectangular blank 90 as shown in FIG. 8. The cardboard sheet for the blank 90 is constructed as previously discussed for the box sheets. The insert member 30 has a center panel 92 defining a central oval hand grip cut out 94 which is hinged 95 at its upper surface. The oval cut out 94 is preferably about 3 inches in length and 2 inches in height. Two parallel fold lines 96 and 98 intersect the top edge 93 and bottom edge of the insert member 30 rectangular blank to form a fold section 97 on each side of the central panel 92. The outer fold line 98 is integral with an adjacent outer end panel 100 on each end of the rectangular insert member blank. Each outer end panel 100 is glued to the inner surface of the side panels 60, with the fold section 97 being spaced over and not engaging the box corners. End tab 66 and end member 46 is glued to the center panel 92 as seen in FIGS. 2, 3 and 5. The insert member 30 is preferably 25 inches long and 6 inches in height. The central section 92 of the insert member is 12 inches in width, the fold section 97 of the insert member is 2 inches in width and the outer end panels 100 of the insert member are each 4.08 inches in width.

[0060] The cover of the box 20 consists of overlapping rectangular panels 82 and 82 each of which is integral to one of the side panels 60. The cover panels 82 and 82 are folded inward along fold lines 84 to overlap and form the cover for box 20. Each cover panel 82 has a rectangular tab 86 extending outward from the end of the cover panel. The tabs 86 each define a rounded corner 88 as seen in FIGS. 2, 3, and 6. The tabs 86 are folded along fold line 87 so that the tabs can be inserted over box 20 and glued to the outside surface of the insert central panel 92 when the cover is closed. This enables the box 20 to remain closed once it is filled with product. One of the cover panels 82 has a width ranging from 1 inches to 1, preferably 1 inches which is greater than the width of the opposite cover panel 82 so that it overlaps the opposing cover panel as seen in FIG. 1.

[0061] The corrugated material forming the box 20 and insert members 30 are impregnated and coated in the same manner as previously described.

[0062] Another embodiment of the invention is an alternative leak resistant corrugated box 200 as shown in FIGS. 9-11 having a box blank 201 as shown in FIGS. 12-14. The box blank 201 is cut and scored in the box cutting station to form a bottom panel 202 with opposing integral end panels 204 and 206 each being joined to bottom panel 202 at the fold lines 205 and 207. Each of the end panels 204 and 206 has a partial hand cut out 208 with a lower hinge portion 209.

[0063] Side wall panels 210 and 212 are positioned on opposite sides of bottom panel 202 and are integral thereto being joined to the bottom panel 202 along their respective fold lines 211 and 213 allowing the side panels 210 and 212 to be folded upward and positioned transverse to the plane of the bottom or base panel 202. Each of the ends of the side panels 210 and 212 is integral with end reinforcing panels 220 and 222 and is joined to the end reinforcing panels by fold lines 221 and 223. The end reinforcing panels 220 and 222 are positioned on opposite ends of each of the side panels 210 and 212 and each end reinforcing panel defines a U-shaped cut out 228 in its distal end which fits adjacent to and around slightly less than of the respective end panel cut out 208 leaving a gap 223 as shown in FIG. 10. Each of the end reinforcing panels 220, 222 are separated from the respective adjacent end panels 204 and 206 by parallel cuts 224, 226. These cuts allow the respective end reinforcing panels to be separated from the end panels 204 and 206 and folded to a transverse position so that U-shaped cut outs 228 of the reinforcing end panels are aligned with cut outs 208 of the end panels 204 and 206. Cut lines 224 and 226 are cut down the sides of end panels 204 and 206 respectively and reinforcing panels 220 and 222 but do not engage or intersect the fold lines 205 and 207 of the end panels or the fold lines 221 and 223 of the end reinforcing panels 220 and 222. It should be noted that fold lines 221 and 223 are offset from the fold lines 205 and 207 as shown in the area of dashed circle A, allowing corner tab 300 to be folded inward. The cut lines 224 and 226 end in the blank about 5/8 inch to about inch from the fold lines 205 and 221 and fold lines 207 and 223 as shown in FIGS. 10 and 12. When the adjacent reinforcing end panels are folded inward and the adjacent end panel is folded upward, they form an end panel assembly perpendicular to the bottom panel 202 as shown in FIG. 10. A corner seal tab 300 is formed by an upper angled cut 301 cut on angle about 45 from the end of cutline 224 or 226 in the end panel 204, 206 and a second distal score line 302 is made in the bottom corner of the respective end panel. Score line 302 if extended would intersect the upper angled cut 301. This tab area is also crushed by a die for easier folding. The cut 301 and score line 302 forms a generally triangular shaped seal tab 300 with its base adjacent and aligned with the either side panel fold lines 211 or 213 to form a pinched corner seal as best seen in the perspective views of FIGS. 10 and 11. As noted, the base of the triangular shaped tab 300 runs along the axis of line 211 or 213 and runs from the proximal end of cut 226 to the offset intersection of fold line 221 or 223 depending on the tab location of the corner of the box.

[0064] The pinched triangular shaped corner tab 300 ranges from inch to about 1 inch in length depending upon the length of angular cut 301 into the end panel and the corner seal depth desired when the box is assembled. The angular cut 301 is preferably at a 45 angle to fold line axis 211 or 213. The triangular shaped corner tab 300 preferably is crushed in the blank by the die as previously noted to allow easier folding. It should be noted that end reinforcing panel fold lines 221, 223 and the end panel fold line 205, 207 are offset 1/16 inch to 3/16 inch as shown in the FIGS. 12-14 so that the bottom panel 200 is slightly offset from the side panels 210 and 212 allowing the reinforcing panels 220 and 222 to be folded and positioned adjacent the end panels 204 and 206 and the crushed corner tabs 300 to be folded. The corner tabs 300 thus form a leak resistant seal for each corner of the box extending upward a predetermined distance preventing drainage of fluid at the corners which has leaked from the contained poultry, meat, seafood or produce into the box chamber.

[0065] The box 200 when folded has the reinforcement panels 220 and 222 folded inward and aligned to each other and parallel to the end panels 204 and 206. The end panels 204 and 206 are positioned on the outside of the box forming the exterior panel of the end panel assembly. All four reinforcing panels 220 and 222 are provided with a partial hand cut outs 228 which align with the hand cut outs 208 of end panels 204 and 206 when the box is assembled. As shown in FIG. 10, neither of the reinforcing panels free end edges engages the opposite end panel. The box 200 is provided with a standard lid or cover 250 which is well known in the art and is shown in FIGS. 10 and 11.

[0066] FIGS. 12-14 show different dimensioned box blanks according to the present invention in order of increasing depth. FIG. 12 is a box blank 33 inches in length and 26 inches in width forming a box 19 inches by 12 inches with a 7 inch depth. FIG. 13 is a box blank 35 inches in length and 28 inches in width forming a box 19 inches by 12 inches with an 8 inch depth. FIG. 14 is a box blank 38 inches in length and 31 inches in width forming a box 19 inches by 12 inches with a 9 inch depth.

[0067] FIGS. 15-17 show multiple box blanks of this embodiment cut and scored in a single sheet of cardboard which correspond to the single box blanks in FIGS. 12-14. FIG. 12 shows single sheet of the box blank shown in FIG. 15, FIG. 13 shows a single box blank equating to the multiple blanks of FIG. 16 and FIG. 14 shows a single box blank equating to the multiple blanks of FIG. 17.

[0068] The principles, preferred embodiments and modes of operation of the present invention have been described in the foregoing specification. However, the invention should not be construed as limited to the particular embodiments which have been described above. Instead, the embodiments described here should be regarded as illustrative rather than restrictive. Variations and changes may be made by others without departing from the scope of the present invention as defined by the following claims:
