Description

METHOD AND APPARATUS FOR COMPRESSING AND HOLDING IN COMPRESSION WOVEN FABRIC ARTICLES

BACKGROUND OF THE DISCLOSURE

[0001] This application claims priority under 35 U.S.C. § 1 19(e) of provisional patent application serial number 61/304,734, filed on February 15, 2010, the contents of which are incorporated by reference.

Field of the Disclosure

[0002] The present disclosure relates to a method and apparatus for producing compact shipping for woven fabric articles or compressible materials, such as, but not limited to, bedding materials.

Description of the Prior Art

[0003] In the prior art, it is well known to package woven fabric articles or compressible materials, such as bedding material, in a package or bag made from polymeric or similar material. However, the resulting packaging can be bulky which increases transportation, storage and display costs throughout the chain of commerce. Similarly, a consumer may be less prone to buy an unwieldy package.

[0004] The storage of polymeric bag within a box is disclosed in U.S. Patent No.

7,588, 160, entitled "Combined Storage Apparatus", issued on September 15, 2009 to Chen.

SUMMARY AND OBJECTS OF THE DISCLOSURE

[0005] It is therefore an object of the present disclosure to provide a method and apparatus for compressing woven fabric articles or compressible materials, such as, but not limited to, bedding materials, in order to provide a compact and aesthetically pleasing package. [0006] This and other objects are attained by the present disclosure by providing a method and apparatus wherein compressible materials are placed into a plastic storage bag, typically of the type with an air valve and a reclosable zipper. The zipper remains open, and the compressible material and plastic storage bag are compressed, typically with a pneumatic or hydraulic apparatus. After the compression step has been performed, the zipper is closed thereby retaining the package in its compressed state. The plastic storage bag, with the compressed woven cloth material therein, is then placed into a reusable tote bag, typically including a clear vinyl portion. This results in an aesthetically pleasing container for display and sale to the customer. This further results in a tote bag and plastic storage bag which may be used by the consumer after the retail sale of the compressible material within the plastic storage bag and the tote bag.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[00016] Referring now to the drawings in detail wherein like numerals indicate like elements throughout the several views, one sees that Figure 1 is a perspective view of pressing apparatus 10 of the present disclosure. Pressing apparatus 10 includes a frame 12, typically made from metal, which further includes a ground-engaging rectangular base 14, upright vertical elements 16 at the corners, and an upper horizontal portion 18. Tray 20 is positioned on rectangular base 14. Tray 20 typically includes an extended floor 21 which can serve as a feeding ramp. Tray 20 further typically includes first and second side elements 22, 24 which are inwardly and outwardly adjustable to accommodate different sizes of packages and may be configured as being movable. Tray 20 further typically includes rear element 25. Rear element 25 may be hinged to provide further access to package 100 (to be described) and to allow the package 100 to be pushed out of the rear of pressing apparatus 10. The use of first and second side elements 22, 24, along with rear element 25, allows the package 100 (to be described) to be compressed into a controlled shape, with the contents typically remaining very flat and smooth. Additionally, different shapes for the resulting product may be achieved by placing elements into different configurations.

[00017] Compression arm 30 reciprocates vertically toward and away from tray 20.

Compression arm 30 includes flat compression plate 32 (typically sixteen by sixteen inches for applications involving bedding materials) which moves toward and away from tray 20 and impinge against the package 100 (to be described). The compression plate 32 provides a compression surface and is connected by first and second horizontal cross-beams 34, 36 which are, in turn, connected to respective first and second vertical guide rods 38, 40 which are engaged by respective first and second guide apertures 39, 41 and thereby constrained to vertical motion. Vertical drive rod 37 is connected between pneumatic drive 48 and compression plate 32. Pneumatic drive 48 thereby moves compression plate 32 vertically and applies a force to compression plate 32, thereby causing a compression force to be exerted across the area of compression plate. It has been found that a force of at least 2.5 to 3.5 pounds per square inch typically is required for sufficient compression of most compressible materials, such as, but not limited to, woven textile or cloth, particularly those frequently used for bedding materials.

[00018] Figures 2, 3 and 4 illustrate the steps of compressing the package 100. In Figure 2, compressible material, such as, but not limited to, textile, cloth or woven material (typically, a comforter set or bedding set 102), is placed within a sealable storage bag 104 of the type shown in Figure 8, and placed upon tray 20 of pressing apparatus 10, wherein the first and second side elements 22, 24 and rear element 25 of tray 20 have been adjusted in accordance with the desired dimensions of the final package 100. As shown Figure 8, sealable storage bag 104 includes front and rear walls 106, 108, typically of transparent polymeric material, with an airtight or leak-resistant reclosable zipper 1 10 with first and second interlocking profiles 1 12, 114 which can be selectively opened (separated) or closed (interlocked) by movement of optional slider 1 15. Additionally, one of the front and rear walls 106, 108 includes a reclosable air valve 1 16 with an open position which allows air to pass freely therethrough and a closed position which provides an airtight or leak-resistant configuration.

[00019] After the comforter set 102 is placed in the sealable storage bag 104 as shown in Figure 2, the reclosable zipper 1 10 is left at least partially open and the pneumatic drive 48 is activated thereby forcing compression plate 32 downwardly thereby compressing the package 100, including comforter set 102 within sealable storage bag 104 and driving, expelling or evacuating at least a portion of the air from the sealable storage bag 104 through reclosable zipper 1 10. It has been found that, typically, it is preferable to perform this operation at normal atmospheric pressure without any vacuum apparatus being applied to reclosable air valve 1 16 or any place else on the resealable storage bag 104 as such a vacuum operation typically deforms the comforter set 102, rendering it unsightly. In other words, a uni-directional compression is preferred over the spherical compression that would typically occur in the presence of a vacuum. Similarly, it has been found that applying vacuum to fur or to suede is particularly unsightly. After the pressing apparatus 10 has compressed the storage bag 104 and the contents thereof and driven air out through reclosable zipper 1 10 as shown in Figure 3 (with the reclosable zipper 1 10 at least partially open), the reclosable zipper 1 10 is closed (as well as reclosable air valve 1 16, if not already closed) thereby rendering the storage bag 104 airtight or leak-resistant and maintaining the reduced size of storage bag 104 and the contents thereof, as shown in Figure 4. An alternative aspect of the disclosure may close the zipper 1 10 prior to compression and expel the air through the reclosable air valve 1 16 during compression and then close the air valve 1 16 after compression. However, this aspect may not be preferred in some higher speed operations. The air valve 1 16 is typically provided in order to provide the consumer with a vacuum storage bag after purchase of the entire product of Figure 7 in a retail establishment.

[00020] The storage bag 104 is then removed from the pressing apparatus 10 and placed into the forming section 200 of the packaging shown in Figure 7. Alternatively, the pressing operation may be executed with the forming section 200 in place around the storage bag 104. Forming section 200 includes rigid or semi-rigid bottom panel 202 and two rigid or semi-rigid side panels 204, 206. Panels 202, 204, 206 are sized for flush insertion into tote container or bag 300. Strap portions 208, 210 extend from bottom panel 202 and terminate in respective snap buckle portions 212, 214. Snap buckle portions 212, 214 can inter-engage in a conventional manner to form first strap 216. Likewise, strap portions 218, 220 extend from bottom panel 202 and terminate in respective snap buckle portions 222, 224. Snap buckle portions 222, 224 can inter-engage in a conventional manner to form second strap 226.

[00021] Strap portions 208, 210, 218, 220 are engaged tightly around storage bag 104 and snap buckle portions 212, 214 and 222, 224 are inter-engaged to each other to form first and second straps 216, 226 which are tightly wrapped around storage bag 104, thereby constraining storage bag 104 and maintaining the size and shape of storage bag 104.

[00022] The storage bag 104, with forming section 200 engaged thereto, is then placed within cloth tote container or bag 300, which serves as an outer container typically formed as a luggage-type container, thereby further constraining storage bag 104. Tote container or bag 300 includes a bottom wall 302 with a square or rectangular shape and four side walls 304, 306, 308, 310 extending therefrom. Top wall 312 extends from side wall 304 and includes cloth zipper 315 around three sides thereof for releasable attachment with side walls 306, 308 and 310. The terms "top", "bottom" and "side" are arbitrary in this context as the orientation of tote container or bag 300 can be easily changed. Further, top wall 312 typically includes transparent window or portion 313 so as to allow the purchaser to see the contents of storage bag 104. Side wall 308 includes handle 314 sewn or otherwise attached thereto, thereby allowing a customer to carry the tote container or bag 300, with the storage bag 104 and comforter set 102 therein.

[00023] After the storage bag 104 and comforter set 102 have been placed into the tote container or bag 300, an optional fabric sample 400 (matching in appearance to the comforter set 102) may be placed over the storage bag 104, including the comforter set 102, and the zipper 315 of tote container or bag 300 closed, so that the display through transparent top wall 102 is more aesthetically pleasing.

[00024] In this way, an appealing and compact package for the comforter set 102 (or similar woven or similar material objects) is achieved as shown in Figure 6. This results in a vacuum storage bag being sold in a retail establishment with the compressed product within the vacuum storage bag, so that the product may be removed and the vacuum storage bag and tote bag reused by the consumer. Moreover, a comparison between the size of the tote container 300 resulting from the present embodiment and the size of conventional packaging 500 of bedding materials is shown in Figure 6. A typical size of prior art packaging for a queen size set is 21 inches by 16 inches by 12 inches, while the present embodiment may achieve a size of 21 inches by 16 inches by 6 inches, or a reduction in volume of fifty percent.

[00025] Thus the several aforementioned objects and advantages are most effectively attained. Although preferred embodiments of the invention have been disclosed and described in detail herein, it should be understood that this invention is in no sense limited thereby and its scope is to be determined by that of the appended claims.
