DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(15) Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.

(16) A method for packaging a product, in accordance with the present preferred embodiments, and with reference to FIGS. 1A-1C, comprises utilizing a die-cut, and scored pad 100. Die-cut and scored pad 100 is preferably a planar corrugated cardboard pad, but is not limited to this configuration. For example, but not by way of limitation, a chip board or a corrugated plastic pad could be used as the die-cut, scored pad 100. Other materials also would fall within the scope of the present invention. As broadly embodied in FIGS. 1A-1C, corrugated pad 100 is generally rectangular in shape, and includes upper and lower edges 110 and 112, and right and left edges 114 and 116. An example of a pad 100, as embodied in FIGS. 1A-1C, dimensions for the pad 100 include a length L of approximately 81.75 inches, and a width W of approximately 65.7593 inches; the actual dimensions of pad 100, as used in accordance with the invention, however, will vary depending on the dimensions of the product being packaged and shipped.

(17) A right vertical score line 118 is provided inset from the right edge 114, and a left vertical score line 120 is provided inset from the left edge 116. As embodied in FIG. 1A, vertical score lines 118 and 120 are preferably substantially parallel with respect to one another. An upper horizontal score line 122 is provided inset from the upper edge 110, and a lower horizontal score line 124 is provided inset from the lower edge 112. As embodied in FIGS. 1A-1C, horizontal score lines 122 and 124 are preferably substantially parallel to one another, and are preferably substantially perpendicular to right and left vertical score lines 118 and 120, respectively. In addition, the number of right and left vertical score lines, and the number of upper and lower horizontal score lines can vary, depending on the product to be packaged and shipped.

(18) As embodied in FIGS. 1A-1C, vertical score lines 118 and 120 include a plurality of die-cut tabs 126 provided at spaced-apart positions along the length of the right and left vertical score lines 118 and 120. Each of the die-cut tabs 126 include two preferably parallel die-cut slots 126a and a die-cut edge 126b connecting the two die-cut slots 126a. In addition, die-cut slots 126c are provided extending inward from the upper and lower edges 110 and 112.

(19) The various score lines 118, 120, 122, and 124 described above and depicted in FIG. 11, also define portions of the corrugated pad 100, including a central portion 130, an upper portion 132, a lower portion 134, a right portion 136, and a left portion section 138. An example of the upper and lower portions, and the right and left portions, is embodied in FIGS. 1A-1C. The upper and lower portions 130 and 132 each measure approximately 12 inches by 63.75 inches, and the right and left portions 134 and 136 each measure approximately 11.5 inches by 58.75 inches. The actual dimensions, however, in accordance with the present invention, will vary depending on the dimensions of the product to be packaged and shipped.

(20) The upper portion 132 and the lower portion 134 are configured to fold inward along their respective die-cut score lines 122 and 124 in a first direction, and along die-cut slots 126c toward the central section 130, as depicted in FIGS. 3A-3B, 4A-4B, and 5C-5D. When the upper and lower sections 132 and 134 fold inward, corrugated pad 100 separates along the die-cut score lines 126c.

(21) As embodied in FIGS. 2A-2D, 3A-3D, and 4A-4D, the shipping method and package of the present invention can be used to ship any size product P, from a relatively small, non-bulky, lightweight product, such as a mobile phone depicted in FIGS. 2A-2D, to a relatively large, bulky, heavyweight product such as an automobile door depicted in FIGS. 3A-3D and 4A-4D.

(22) As embodied in FIGS. 2A-2D and 3A-3D, upper and lower portions 132 and 134 are folded toward the central section 130, and into contact with a portion or portions of the product P proximate the nearest respective score line.

(23) After the upper and lower portions 132 and 134 have been folded, and the product P placed on the central portion 130, the pad and the product are placed on a conveyer belt leading into an automated wrapping tunnel (not shown). In a preferred embodiment, the pad 100 and the product P will move linearly through the automated wrapping tunnel on the conveyer belt. As embodied in FIGS. 2B, 2C, 3B, and 3D, at least one turn of pre-tensioned restraining material is wrapped around the pad 100 and the product P in a top to bottom orientation, enveloping the door. The amount of pressure applied to the folded-over upper and lower portions 132 and 134 by the restraining material preferably falls within a range of 10 psi through 25 psi, and most preferably 20 psi. In the embodiments of FIGS. 2B, 2C, 3B, and 3D, the restraining material is a plastic sheet wrap 140. When plastic sheet wrap 140 is used as the restraining material, the preferred plastic sheet wrap is 80 gauge pre-stretched film, capable of withstanding at least 20 lbs, of tension, used to work with loads weighing up to 2200 lbs. The number of turns of plastic sheet wrap 140 is determined based on the dimensions of the product P to be packaged and shipped. In certain packaging applications depicted in FIGS. 4A-4B, for example when a large volume of products P are to be packaged and shipped, it may be more cost effective, and within the scope of the invention, to use strapping 142 as the restraining material, in place of the more expensive plastic sheet wrap.

(24) After the wrapping, the right and left portions 136 and 138 are folded along their respective score lines, toward the product P until they reach an upright position perpendicular to the central portion 130, as shown in FIGS. 2C-2D and 3C-3D. In the perpendicular position, the right and left portions 136 and 138 will contribute to suspension of the pad 100 and the product P, when they are inserted into a master shipping container 150, as discussed below.

(25) When the right and left portions 136 and 138 fold upward to the perpendicular position, the die-cut tabs 126 will separate from the central portion 130. As embodied in FIGS. 2D, 3C, and 3D, when the die-cut tabs separate from the central portion 130, the die cut edges 126b extend to an extended position below the central portion 130, perpendicular to the central portion 130, and aligned with one another.

(26) The wrapped central portion 130 and product P are inserted into the master shipping container 150. As embodied in FIGS. 2C-2D and 3C-3D, the restraining material wrapped around the central portion 130 and the product P resists movement of the product P with respect to the pad 100, while the upright right and left sides 114 and 116 cooperate with the extended aligned die-cut tab edges 126b to suspend product P within the master container 150, both to prevent movement, and to prevent portions of the product P from contacting inner surfaces of the master container 150.

(27) Once the corrugated pad 100 and the product P are inserted fully into the master shipping container 150, the outer flaps are shut and sealed, and the master container 150 is ready to be shipped.

(28) FIGS. 5A-5D depict another embodiment of the invention, substantially identical to the embodiments of FIGS. 1A-4D, except that one of the upper and lower portions 132 and 134, upper portion 132 as embodied in FIG. 5B is folded inward, into die-cut slot 126c before the product P id placed on the central portion 130, as embodied in FIG. 5C, with a portion P1 of the product P resting on the folded-in upper portion 132. As embodied in FIG. 5D, the lower portion 132 is next folded inward into contact with product P, and secured into contact, preferably with an adhesive 144. The restraining material, plastic sheet wrap in FIG. 5D, is wrapped around the central portion 130 and the product P. The remainder of the packaging and shipping steps are identical to those described above with respect to FIGS. 1A-4D. The embodiment of FIGS. 5A-5D is most suitable for use when packaging and shipping certain products P. For example, although an automobile door is depicted in FIGS. 5A-5D, this embodiment is particularly well-suited for packaging and shipping a vehicle windshield or the like.

(29) The invention has been described with respect to the die-cut portions being defined in the right and left vertical score lines, the upper and lower portions being folded into contact with the product P on the central portion and wrapped, and the right and left portions being folded upward to the vertical position perpendicular to the central portion, in order to, with the die-cut tab edges, hold the product suspended within the master container. The pad also could be oriented such that the die-cut portions are defined in the upper and lower horizontal score lines, the right and left portions are folded over into contact with the product P and wrapped with the restraining material oriented in a side to side orientation, and the upper and lower portions are folded to the upright position perpendicular to the central portion, in order to cooperate with the perpendicular aligned die-cut tab edges to suspend the product within the master container.

(30) The invention has been described with the wrapping being performed by an automated process. Other or all of the steps in the disclosed process of packaging the product for shipping could be performed using automated machinery and still fall within the scope of the present invention.
