1. Field of the Invention
The present invention relates generally to clothes hangers, and more particularly to environmentally friendly hanger constructions that include a paperboard body with a first and a second panel, at least one central tab extended from a peripheral edge of one of the panels, and a polymeric hook secured the paperboard body using the central tab.
2. Background of the Related Art
Numerous hangers have been developed as alternatives to conventional metal and plastic hangers. U.S. Pat. No. 5,868,289 discloses a folded paperboard hanger that includes a slant plate part 1 having two slant portions, and a connecting plate part 2 that is connected to the ends of the slant portions, so as to form an isosceles triangular structure. A hanging plate part 3 is integrally formed with the slant plate part for hanging the hanger and a reinforcement plate part 4 extends at a 90-degree angle from either the slant plate part 1 or the connecting plate part 2, so as to stiffen the hanger.
U.S. Pat. No. 5,027,945 discloses a merchandise support assembly that includes a paperboard blank 10 having first, second, third, fourth, and fifth portions 12, 14, 16, 18, and 26, respectively, folded at crease lines 20, 22, 24, and 28. The second portion 14 is folded at the crease line 20, so that it overlies part of the first portion 12 to which it is secured by adhesive. Folding at crease lines 20, 22 forms a pocket between the second and fourth portions 14, 18 that are spaced apart by the width of the third portion 16. A hook 40, which is made from a stiff flexible plastic material, includes a hook member 42 and flexible resilient support arms 46 inserted through an opening 38 adjacent a fourth crease line 28 at the junction of the first and fifth portions 12, 26. The arms 46 engage the sheet material along crease line 28 to support the folded blank 10.
U.S. Patent Application Publication No. 2004/0031825A1 discloses a garment hanger that includes two parts or elements 2, 2′ that are hinged together so that they can be folded from a first relatively flat or opened out configuration to a second configuration in which the two parts or elements are adjacent and facing each other. At least one of the parts including first means 15, a hook, by which the hanger can depend from a support when in its second configuration. The two parts provide a second means 12, shoulders, from which a garment can be hung. The two parts or elements are preferably of a flexible stiff sheet material, such as a corrugated material, e.g. corrugated cardboard.
The hanger designs discussed above pose several disadvantages. Hangers that are manufactured entirely from paper do not provide enough support to become acceptable substitutes especially in retail markets. Once a weak spot is formed in the hook portion of an all paper hanger, structural failure quickly results no matter how reinforced the paper. Further, all paper construction cannot be used with standard dry cleaning equipment because the hangers will tear or shred.
Moreover, previous hanger designs that utilize separate non-paper hooks often have weak attachment mechanisms. For example, the cantilevered support arms of the hook in U.S. Pat. No. 5,027,945 are simply manipulated into place between the paperboard layers of the hanger. No adhesive is used to secure the support arms of the hook within the paperboard hanger body. Designs, which rely on the flexural strength of the hook support arms or use a paper hook cannot support heavy garments.
Billions of hangers are discarded each year. Only 15% of hangers are typically recycled with most going into landfills. Thus, there is a need for an environmentally friendly, easy-to-use, and structurally sound hanger that can be manufactured quickly and at an acceptably low cost.
One aspect of the present invention is directed to an apparatus for hanging articles, such as clothing, that includes, inter alia, a hanger body and a polymeric hook and methods for making the same. The hanger body has first and second paperboard panels separated from one another by a fold line. The first paperboard panel includes a central tab, which extends from a periphery thereof, opposite the lower edge thereof. The polymeric hook engages with the central tab of the hanger body and includes a support portion and a hook base. The hook base has an alignment aperture formed therein through which the central tab of the first paperboard panel is inserted so as to secure the polymeric hook to the hanger body.

These and other features of the subject invention will become more readily apparent to those having ordinary skill in the art from the following detailed description of preferred embodiments.
Reference is now made to the accompanying figures for the purpose of describing, in detail, exemplary embodiments of the present disclosure. The figures and detailed description are provided to describe and illustrate examples in which the disclosed subject matter may be made and used, and are not intended to limit the scope thereof.
Referring now to the accompanying figures, there is illustrated in
In
Hanger body 1 is manufactured from 100% recyclable material. Hanger body 1 is manufactured from paperboard having a thickness between about 30 to about 38 point paperboard. Those skilled in the art will appreciate that materials other than paperboard may be used to manufacture the hanger body 1. Materials that provide similar strength as paperboard may be used, for example, corrugated paperboard, linerboard, corrugated e-flute, and other biodegradable substrates such as polylactic acid.
It should be noted that the shape of the hanger body 1 may be modified, as desired, without departing from the spirit of the invention. For example, it may be desirable to change the shape of the hanger body 1 to accommodate hanging a particular item. Further, it may be desirable to include additional perforated regions to accommodate accessories, straps, or other such alterations.
As shown in
The width of alignment aperture 9 is slightly larger than the width of the central tab 5 base. The alignment aperture 9 of the polymeric hook 6 has internal curves 9a and 9b that adapted and configured to engage with the periphery of the central tab 5 to create a self-locating mechanism when the central tab 5 is folded over. The self-locating mechanism serves to center the polymeric hook 6 on the central tab 5 of the hanger body 1.
Careful consideration was given to the height, width, and thickness of the polymeric hook 6 so that it is manufactured to specifically fit within equipment found in dry cleaning businesses. The polymeric hook 6 is approximately between about 4 inches and about 4.5 inches in height and approximately between about 2.5 and about 3.75 inches wide. The support portion 7 itself is approximately between about 0.3 to about 0.45 inches wide and may or may not narrow toward the tip of the polymeric hook 6. Preferably, the polymeric hook 6 is manufactured so that the thickness permits at least 6 polymeric hooks to fit within a slot of a commercial dry cleaning belt. More preferably, the polymeric hook 6 is between 0.075 to about 0.090 inches thick. The polymeric hook 6 may be dimensioned or configured to allow for marking, advertisement, and/or branding area 308b as shown in
The polymeric hook 6 is manufactured from 100% post consumer recycled product. Polymeric hook 6 is manufactured from a thermoplastic polymer. In certain embodiments, the polymeric hook 6 can be manufactured from material selected from the group consisting of low-density polyethylene, high-density polyethylene, and polypropylene. Those skilled in the art will appreciate that materials other than that of the present embodiment may be used to manufacture the polymeric hook 6 such as biologically based polymers made from items such as corn or sugar, and synthetically grown fabrics.
In
Pants hanger 15 and the items attached thereto including the support bar 16, securing arms 19, attachment means 20, and bendable clips 17 are manufactured from a thermoplastic polymer. In a preferred embodiment, pants hanger 15 and the items attached thereto are made from recycled or recyclable material. In certain embodiments, the polymeric hanging bar 15 and its related items can be manufactured from material selected from the group consisting of low-density polyethylene, high-density polyethylene, and polypropylene. Those skilled in the art will appreciate that materials other than that of the present embodiment may be used to manufacture the pants hanger 15 such as biologically based fabrics made from items such as corn or sugar, and synthetically grown fabrics. Further, pants hanger 15 may be perforated (as shown) or hollowed by other means to make it light weight.
Those skilled in the art will appreciate that the fingers on the pants hanger 15 can be manufactured from any materials that will create friction between the items to be hung on the pants hanger 15 and the fingers. These materials include the materials used to manufacture the polymeric hook 6 and/or materials other than that of the present embodiments may be used to manufacture the such as biologically based fabrics made from items such as corn or sugar, and synthetically grown fabrics.
Referring now to
The position labeled C illustrates a polymeric hook 6 for hanging clothing that is provided comprising a base portion 8 that defines an alignment aperture 9 and a support portion 7 extending from the base portion 8. The polymeric hook 6 is dispensed onto the folded central tab 5. The polymeric hook 6 is located and locked with the folded central tab 5. Adhesive is applied on an inner surface of the central tab 5. The central tab 5 is folded into engagement with the first paperboard panel 2 so as to secure the polymeric hook 6 to the hanger body 1. Adhesive is applied to an interior surface of at least one of the first or second paperboard panels 2 and/or 3 of the hanger body 1. The position labeled D illustrates that the second paperboard panels 3 is placed over onto the first paperboard panel 2 to capture the hook 6 and central tab 5. An alternative embodiment further includes compressing the assembled polymeric hook 6 and hanger body 1. It is understood that although the positions are depicted in an order in
Preferably the adhesive applied to the garment hanger is a hot melt adhesive or a cold melt adhesive.
The fold line at the bottom edge of the first and second panels 2 and 3 functions like and I-beam and increases the rigidity of the garment hanger 100.
The polymeric hook 6 and its self-locating and locking mechanism with the central tab 5 provide greater strength than previous hanger embodiments. The leaf tabs 211a and 211b provide even greater strength to the garment hanger by providing more surface area for adhesive to be applied.
The leaf tabs 211a and 211b also allow the polymeric hook 6 to be applied and aligned at ultra high speeds thereby allowing a higher rate of processing garment hangers. The garment hangers of the present invention can be produced at speeds of 21,000 to 22,000 hangers per hour. Previous hanger embodiments constructed entirely of paper were capable of producing only 8000 hangers per hour. The present invention provides a clear advantage over previous embodiments by permitting a higher output of garment hangers made of recycled and recyclable materials at a lower cost. Speed of manufacture is critical because hangers are a low cost item.
The hanger bodies 1 are designed in such a way as to allow for maximum nesting on a single piece of paperboard or other desired material as shown in
Hanger embodiments that have fold lines at the top of the hanger body cannot nest as many hanger bodies onto a single sheet of paperboard material. Moreover, without the increased area of a hook, more hanger bodies 1 can be nested on a single piece of paperboard than hangers that are manufactured entirely from paper. Due to the combination of the paperboard hanger body 1 and the polymeric hook 6, the present invention is manufactured in a way that increases speed by 300 percent over all paper hanger alternatives with equivalent hook strength (4-ply hook) and reduces costs by at least 45 percent. The claimed invention removes the tedious and slow folding process required by previous hanger embodiments constructed entirely of paper and reduces the amount of paper used.
Further, the present invention uses an extrusion process to produce the polymeric hook at widths acceptable to fit in and durable enough to be used with at least 99 percent of standard dry cleaning machinery. This is another clear advantage over previous embodiments of previous alternative hanger designs, especially all paper hook constructions that would be easily shredded on standard dry cleaning machinery.
The following example provides strength comparisons between the claimed invention and conventional hanger constructions.
Three-ply, 4-ply, 13-gauge white coated wire, polypropylene (PP) plastic, and high density polyethylene (HDPE) hangers were strength tested using a vertical pull test. The hook or hanger was placed in a gripper vice from below and the hook was connected to a “S” hook for the vertical pull. The hook was pulled to the point of failure at a rate of 10 inches per minute and the maximum readings were recorded for the various hangers. The paper hooks were tested in two conditions: prebroken (with a weak spot) and pristine. The results are recorded in Table 1.
As shown in Table 1, the 0.090 inch thick polypropylene hook of the claimed invention produced the best overall results to the vertical strength test. Although the 4-ply paper hook and the 0.090 inch thick polypropylene hook of the claimed invention resulted in averages very close to one another, several of the 0.090 inch thick polypropylene hook trials resulted in values higher than the average for the 4-ply paper hook. Also, once the 4-ply paper hook incurred damage or was “broken” the vertical test results dramatically fall below the averages of the hook of the claimed invention. The 0.090 inch thick polypropylene hook of the current invention provides greater strength than previous hanger embodiments.
It should be noted that while the applicability of the garment hanger for the dry cleaning industry was discussed at length, the garment hanger of the claimed invention may be adapted for the needs of hanging or displaying in related industries including, inter alia, clothing, accessory, and shoe retail, hospitality, government, military and uniform operations. The claimed invention may also be adapted for in home use.
While the foregoing description includes details, which will enable those skilled in the art to practice the invention, it should be recognized that the description is illustrative in nature and that many modifications and variations thereof will be apparent to those skilled in the art having the benefit of these teachings. It is accordingly intended that the invention herein be defined solely by the claims appended hereto and that the claims be interpreted as broadly as permitted by the prior art.
