[0018] The apparatuses and methods disclosed in this document are described in detail by way of examples and with reference to the figures and images. Unless otherwise specified, like numbers in the figures indicate references to the same, similar, or corresponding elements throughout the figures/images. It will be appreciated that modifications to disclosed and described examples, arrangements, configurations, components, elements, apparatuses, methods, materials, etc. can be made and may be desired for a specific application. In this disclosure, any identification of specific shapes, materials, techniques, arrangements, etc. are either related to a specific example presented or are merely a general description of such shape, material, technique, arrangement, etc. Identification of specific details or examples are not intended to be, and should not be, construed as mandatory or limiting unless specifically designated as such. Selected examples of apparatuses and methods are hereinafter disclosed and described in detail with reference made to FIGU RES.
[0019] Figure 1 generally shows a non-inflated insert 8 for a shoe. The shoe insert 8 has a front section 10 or that portion which will fit in the "toe box", a central section 12 and a back section 14. The shoe insert 8 also has an inflatable bladder to provide for form fitting to the shoe which is actuated by a valve 16. The shoe insert 8 is made from extruded polyethylene or polypropylene film, or any other suitable material as is known in the art. Typically, the shoe insert 8 is made with 100% virgin polyethylene and nylon resins which are recyclable materials. Thus, the shoe insert 8 is recyclable. The insert may also be made from recycled materials.
[0020] While consisting of 3 sections, front 10, central 12, and back 14, the shoe insert 8 is a single piece that when inflated provides support for the shoe structure and integrity. The front section 10 is rounded to fit into the toe box area to help in support of this section of the shoe. The front section 10 is generally larger and bulbous in shape. The central and back sections are more narrow than the front portion.
[0021] The central section 12 contains heat seal "dot" components 18 that force air out and up during the inflation process providing support for the shoe in the vamp and laces area. These "dot" components 18 are inserted during the die cutting process and act to direct air flow as the shoe insert 8 is being inflated via the inflation valve 16. One or more of these dots may be used to direct the orientation of the shoe insert so that the insert forms a left or right orientation upon inflation. The toe box or front section 12 can be pivoted about one or more of the dots 18 to change the orientation to a left or right shoe so that the insert fits within a shoe. Alternatively, the dots can be positioned on one side or the other of a center line of the insert so that the insert will automatically divert in the left or right orientation upon inflation of the insert.
[0022] The back section 14 is cylindrical in shape to fit within the heel box and provides support for this section of the shoe. The back section 14 also contains the one-way inflation valve 16, or any other suitable valve as is known in the art. A user would manually inflate the inflation valve 16 or a machine could inflate the valve 16. Once inflated, the shoe insert 8 will be held in the inflated state 90 days or longer.
[0023] Typically, the shoe inserts 8 are inflated after insertion into the shoes, however they can be inflated before insertion as well. If they are inflated before insertion, the waste 20 around the shoe insert 8 is torn off before or after inflation. The waste 20 is only present due to the tooling required to produce the shapes of the shoe insert 8 and does not impact inflation. If the shoe inserts 8 are produced in sheets of material, the entire sheet would be inflated at the same time and then the inflated shoe inserts 8 would be removed from the sheet and inserted into the shoes.
[0024] Additionally, customer facing or branded graphics, artwork, and/or messages can be printed on the inside or outside of the shoe insert 8, depending on the needs and wants of the manufacturer.
[0025] The benefits of the shoe insert 8 are to (1) provide protection for the shoe structure and integrity during the transportation from manufacturing country of origin to retail store globally, and (2) meet or exceed packaging reduction requirements in various global geographies, and (3) provide supply chain costing savings through handling and waste disposal efficiencies.
[0026] The parts are a single piece of polyethylene or polypropylene film, die cut to an identified size and shape not dissimilar to the shape of the inside of a shoe cavity, and a one-way inflation valve inserted in the heel portion. The inside of the film can be printed for branding and graphics by the brand.
[0027] Figure la illustrates the shoe insert 8 in its intermediate condition with a portion of the matrix 26 pulled away from the die cut shape of the insert. The matrix is removable via a series of ties or perforations which easily separate from the die cut area of the shoe insert 8. The edge 13 of the shoe insert 8 is heat seal, that is two layer of plastic are sealed together to form a package that will retain the air or gas once the insert is inflated.
[0028] Figure lb shows the matrix 26 fully removed from the shoe insert. Area or opening designated by reference numeral 28 illustrates were the valve assembly is positioned in the matrix and creates an open end for use in inflating the insert. [0029] Attention is now directed to Figure 2 in which the shoe insert 8 is shown removed from the matrix. As illustrated in Figure 1, the insert 8 has "dot" components 18 which are used to seal portions of the insert together so that the shoe insert 8 will form a right or left shoe insert due to the position or offsetting of the dots. By offsetting the dots from center one can change the orientation of the shoe insert to left or right. Alternatively, if the dot is disposed centrally of the insert the toe box or front portion of the insert can be pivoted or shifted around the dot to form a left or right orientation. Other than the side edges 13 the dots 18 are the only other areas of the insert that are sealed together.
[0030] Turning now to Figure 3, there is shown a view of the inflated shoe insert 8. In this illustration, one heat seal dot 18 is used to direct the front portion 10 of the shoe insert 8 to a right foot configuration. Figure 3 also shows the valve 16.
[0031] Figure 4 shows the show insert 8, in an inflated configuration disposed within a shoe 30. The insert prevents the shoe from being crushed during transit and substantially fills the interior volume 32 of the shoe.
[0032] In order to use the present invention, the insert 18 is removed from the matrix 26 at the production line. The insert can either be inserted into the shoe and then inflated via the valve 16 or in the alternative, the insert can be inflated first and then inserted into the shoe.
[0033] The shoe insert of the present invention provides protection for the toe box and the shape of the shoe during transportation, shipping and handling and prevents the shoe from becoming wrinkled or collapsing during the shipment such that the shoe arrives at its intended retail destination and can be displayed for the retail consumer.
[0034] The shoe insert of the present invention can be created in any number of sizes or styles, for men's, women's or children's shoes, boots or other footwear.
[0035] It will thus be seen according to the present invention a highly advantageous shoe insert has been provided. While the invention has been described in connection with what is presently considered the most practical and preferred embodiment, it will be apparent to those of ordinary skill in the art that the invention is not to be limited to the disclosed embodiment, and that many modifications and equivalent arrangements may be made thereof within the scope of the invention, which scope is to be accorded the broadest interpretation of appended claims so as to encompass all equivalent structures and products.
[0036] The inventors hereby state their intent to rely on the Doctrine of Equivalents to determine and assess the reasonably fair scope of their invention as it pertains to any apparatus, system, method or article not materially departing from but outside the literal scope of the invention as set out in the following claims.
