Description

BACKGROUND

Technical Field

This application relates to a securing structure for securing shoes within a cylindrical container.

Description of Related Art

Traditional rectangular shoe boxes fail to add aesthetic appeal to attract consumers to the shoes inside and fail to stand out in shoe stores full of identical rectangular boxes. A cylindrical container provides a unique artistic quality that may attract consumers and differentiate the product from others on the shelf. However, effectively securing a pair of shoes within a cylindrical container using cost-effective materials presents a new challenge. Furthermore, designing a securing structure for securing shoes within a cylindrical container that can accommodate a variety of different shoe sizes within the same size container presents a further challenge.

DETAILED DESCRIPTION

The Figures (FIGS.) and the following description describe certain embodiments by way of illustration only. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles described herein. Reference will now be made to several embodiments, examples of which are illustrated in the accompanying figures. It is noted that wherever practicable similar or like reference numbers may be used in the figures and may indicate similar or like functionality.

A packaging shuttle secures a pair of shoes in a manner suitable for insertion into a cylindrical container. The packaging shuttle secures the shoes in a stacked configuration such that heel portions of the shoes are supported at the lower and upper ends of the shuttle respectively, and the toe portions of the shoes are supported by a toe-supporting structure at a mid-portion of the packaging shuttle. Removable spacers may be inserted into the packaging shuttle adjacent to the lower and upper ends of the shuttle to enable the packaging shuttle to securely accommodate different size shoes using the same packaging shuttle and cylindrical container.

FIG. 1 illustrates an embodiment of a shuttle 100 securing a pair of shoes 110 (e.g., a first shoe 110-a and second shoe 110-b) for insertion within a cylindrical container 120. The shuttle 100 secures the shoes 110 such that the first shoe 110-a is stacked over the second shoe 110-b (or vice versa) with the shoes oriented in opposite directions. For example, the toe of the first shoe 110-a points downward while the toe of the second shoe 110-b points upward. Furthermore, the bottom soles of both shoes 110 face outward. This configuration supported by the shuttle 100 enables the shoes 110 to be secured within the cylindrical container 120 without damaging the shoes 110 and in a manner that prevents the shoes 110 from shifting during transport of the cylindrical container 120. Furthermore, the shoes 110 are secured in the shuttle 100 without requiring any adhesive or strapping between the shoes and the shuttle 100, thus enabling the shoes to be inserted and removed quickly and simply. Further still, by using adjustable spacers described in further detail below, the shuttle 100 may accommodate a range of different shoe sizes.

FIGS. 2A-B illustrate a detailed view of the shuttle 100. The shuttle 100 comprises a base plate 202, a top plate 204, a first upright support 210 (including a first lower support 212 and a first upper support 214), a second upright support 220 (including a second lower support 222 and a second upper support 224), a first lateral support 216, a second lateral support 226, and a connecting support 230. The shuttle 100 may also optionally include an adjustable lower spacer and an adjustable upper spacer (not shown in FIG. 2) described in further detail below.

The base plate 202 and top plate 204 may each comprise substantially rectangular sheets which may have straight or rounded edges (e.g., straight edges oriented in one direction and round edges along another direction). The major surfaces of the base plate 202 and the top plate 204 may be oriented substantially parallel to each other. The first upright support 210 and the second upright support 220 protrude from the base plate 202 and support the top plate 204. The upright supports 210, 220 each comprise elongated sheets which may form a “lightning bolt” shape described in further detail below. The major surfaces of the upright supports 210, 220 are oriented substantially perpendicular to the base plate 202 and to the top plate 204. The first upright support 210 is connected adjacent to a first edge (e.g., a first straight edge) of the base plate 202 and connected adjacent to a first edge (e.g., a first straight edge) of the top plate 204. The second upright support 220 is similarly connected adjacent to a second edge (e.g., a second straight edge opposite the first straight edge) of the base plate 202 and connected adjacent to the second edge (e.g., a second straight edge opposite the first straight edge) of the top plate 204.

The first upright support 210 comprises a first lower support 212 and a first upper support 214. Similarly the second upright support 220 comprises a second lower support 222 and a second upper support 224. The lower supports 212, 222 are each coupled to the base plate 202 and have respective outer edges that angle away from a central axis through the base plate 202 such that a distance from the respective outer edges to the central axis increases with increasing distance from the base plate 202. The upper supports 214, 224 are each coupled to the top plate 204 and have respective outer edges that angle away from a central axis through top base plate 204 such that a distance from the respective outer edges to the central axis increases with increasing distance from the top plate 204. The angle of the outer edges of the lower supports 212, 222 and upper supports 214, 224 may be approximately equal such that the outer edges are parallel to each other.

The lower supports 212, 222 and upper supports 214, 224 furthermore may all have inner edges approximately parallel to each other. The inner edges of the lower supports 212, 222 may be offset from the inner edges of the upper supports 214, 224 such that an overlap region exists where the lower supports 212, 222 and upper supports 214, 224 respectively meet. The overall shape of the upright supports 210, 220 may thus form lightning bolt or zig-zag pattern as depicted in FIGS. 2A-B and FIGS. 8-10.

The first lateral support 216 connects the first lower support 212 of the first upright support 210 and the second lower support 222 of the second upright support 220. Similarly, the second lateral support 226 connects the first upper support 214 of the first upright support 210 and the second upper support 224 of the second upright support 220. The lateral supports 216, 226 may each comprise a rectangular sheet having a major surface that extends along a plane substantially perpendicular to the plane of the major surfaces of the first upright support 210 and the second upright support 220. The major surfaces of the lateral supports 216, 226 are furthermore each oriented parallel to each other and at an angle relative a central axis perpendicular to the base plate 202 and the top plate 204. Particularly, a distance between the major surface of the first lateral support 216 and the central axis increases with increasing distance from the base plate 202 and decreases with increasing distance from the top plate 204. A distance between the major surface of the second lateral support 226 and the central axis decreases with increasing distance from the base plate 202 and increases with increasing distance from the top plate 204.

A connecting support 230 (shown in dotted lines in FIG. 2A because the surface is obscured) is connected between a lower edge (closest to the bottom plate 202) of the first lateral support 216 and an upper edge (closest to the top plate 204) of the second lateral support 216. The connecting support 230 may comprise a substantially rectangular sheet having a major surface perpendicular to the major surface of the upright supports 210, 220 and oriented at an angle. The connecting support 230 and the lateral supports 216, 226 may meet at a point such that the lateral supports 216, 226 and connecting support 230 have a zigzag cross-section, or the top and bottom edges of the connecting support 230 may be folded to form a horizontal surface that meets with the lateral supports 216, 226. The lateral supports 216, 226 and the connecting support 230 collectively form a toe-securing structure at a mid-portion of the packaging shuttle 100 for securing the toe portions of the shoes as will be described below. Particularly, the combination of the first lateral support 216 and the connecting support 230 form a cavity while the combination of the second lateral support 226 and the connecting support 230 form an upside-down cavity that can respectively support the toes of the first and second shoes 110 as will be described in further detail below.

The shuttle 100 may be made from any suitable material such as cardboard, plastic, or a combination of materials.

In an embodiment, the top plate 202, bottom plate 204, upright supports 210, 220, lateral supports 216, 226, and connecting support 230 may all be formed from a single continuous cut sheet folded into the configuration of FIGS. 2A-B. FIG. 3 illustrates an example embodiment of a cut sheet 300 that can be folded into the shuttle of FIGS. 2A-B. In an embodiment, an adhesive or other fastener may be used to connect non-continuous edges of the cut sheet 300. In alternative embodiments, tabs may be integrated into the cut sheet 300 to enable non-continuous edges to be connected without an adhesive or other external fasteners. Utilizing a shuttle structure that can be formed in this manner form a single cut sheet 300 enables low-cost manufacturing and compact storing of the cut sheets 300 prior to assembly. The cut sheet 300 may be comprised of cardboard, flexible plastic, or other similar material.

FIG. 4 illustrates an embodiment of an assembled shuttle 100 with an optional removable lower spacer 402 and upper spacer 404. The spacers 402, 404 provide support surfaces above the base plate 202 and below the top plate 404 respectively for securing the heel portions of the shoes. By modifying the size of the spacers 402, 404 or removing the spacers 402, 404 entirely, the shuttle 100 can accommodate shoes of different lengths. In an embodiment, the spacers 402, 404 are identically constructed from a folded sheet that can be folded along different lines to create spacers 402, 404 of different heights, thus accommodating different size shoes.

FIG. 5 illustrates an embodiment, of an unfolded spacer 500 that can be used as a lower spacer 402 or upper spacer 404. The unfolded spacer 500 comprises an inner region 506, mid-regions 504, and outer regions 502. The inner region 506 comprises a quasi-rectangular surface that may have rounded or straight edges. The inner region 506 may be sized and shaped to substantially conform to the size and shape of the base plate 202 and top plate 204. The mid-regions 504 connect to respective straight edges of the inner region 506 at fixed fold lines 510 (e.g., perforated lines to accommodate easy folding). The mid-regions 504 include a plurality of parallel selectable fold lines 508 (e.g., perforated lines to accommodate easy folding). Each of the selectable fold line 508 correspond to a different shoe size and may be marked as such. To configure the spacer 500, the spacer 500 is folded along the fixed fold lines 510 so as to form an approximate right angle between the inner region 506 and the mid regions 504. To accommodate a particular shoe size, the spacer 500 is also folded along selected ones of the selectable fold lines 508 corresponding to the desired shoe size so as to form an approximate right angle between the mid-regions 504 and the outer regions 502. The outer regions 506 are folded inwards so as to lay under the inner region 506. FIG. 6 illustrates a partially folded configuration of the spacer 500. FIG. 7 illustrates the folded spacer. When folded in this way, the mid-regions 504 form upright supports for the surface of the inner region 506 with a height dependent on which of the selectable fold lines 508 is selected. The selectable fold lines 508 may be positioned such that when folded in this way, the mid-regions 504 form upright supports of appropriate height to accommodate particular shoe sizes. Thus, spacers of different height may be created from a single pre-folded spacer design such that a range of shoe sizes may be accommodated from the same set of cut sheets. The spacers 402, 404 may be made from any suitable material such as cardboard or plastic.

FIG. 8 illustrates the lower spacer 402 and the upper spacer 404 being positioned within the shuttle 100. Particularly, the upper spacer 404 slides between the upper supports 214, 224 adjacent to the top plate 402 such that the outer regions 502 of the upper spacer 404 contact the top plate 204 and the mid-regions 504 of the upper spacer 404 contact respective inner surfaces of the upper supports 214, 224. In an embodiment, an adhesive (e.g., glue or tape) or other fastener may be used to secure the mid-regions 504 of the upper spacer 404 against the inner surfaces of the upper supports 214, 224 to hold it in place. Similarly, the lower spacer 402 is positioned within the shuttle 100 such that the outer regions 502 of the lower spacer 402 contact the base plate 202 and the mid-regions 504 of the upper spacer 404 contact respective inner surfaces of the lower supports 212, 222 (and may be attached via an adhesive or other fastener).

FIG. 9 illustrates the shoes 110 being placed within the lower and upper portions of the shuttle 100. The toe of the shoe 110-b slides into the cavity formed by the upper lateral support 226 and connecting support 230 and the heel of the shoe 110-b rests against the lower spacer 402 (or base plate 202 if no lower spacer 402 is used). The toe of the shoe 110-a slides into the cavity formed by the lower lateral support 216 and the connecting support 230 and the heel of the shoe 110-a rests against the upper spacer 404 (or top plate 404 if no upper spacer 404 is used).

FIG. 10 illustrates the shoes positioned within the shuttle 100.
