DETAILED DESCRIPTION
Exemplary embodiments are intended to cover all alternatives, modifications, and equivalents as may be included within the spirit and scope of the apparatus and methods as described herein.
Reference is made to the drawings to accommodate understanding of delicate filer packaging apparatus and methods. In the drawings, like reference numerals are used throughout to designate similar or identical elements. The drawings depict various embodiments of illustrative delicate filter packaging apparatus and methods.
Printing system failures may result from filter failure. Filter failure may result from damage caused to the filter during packaging, shipping, and unpacking. For example, filter media packaged in related art packaging using related art methods is susceptible to damage including torn pleats, split pleats, and drag marks caused by deformed pleats.
The damage may arise when filters are packaged and shipped. Damage may also arise during unpacking. For example, a surface of the filter comprising the filter media typically closely faces portions of packaging material that a customer manipulates to remove the packaging. Accordingly, a customer's hands may damage filter media during unpacking. A filter may be damaged by a customer attempting to remove the filter from within a box by handling the filter edges, and accidentally puncturing the filter media, for example. A filter is typically packaged in a protective coating such as a plastic bag, and a customer may drop the filter while opening the plastic bag, or drop the filter while attempting to grasp the filter during removal of the filter form a box.
Filter packaging apparatus and methods in accordance with embodiments may prevent damage to delicate filter media during packaging, shipping, storage, and unpacking. FIG. 1A shows a filter 100 for use in a printing system. In particular, FIG. 1A shows a filter 100 for an iGEN printing system. Other filters for which apparatus and methods may be applicable may have a configuration similar to that of the iGen environmental Unit (EU) Hepa and ozone catalytic media filters, for example. The filter 100 includes a filter assembly 101, and a filter media 105 framed and supported by the filter assembly 101.
The filter media 105 may be configured to form pleats 108, for example. The filter media may comprise a delicate, flame retardant borosilicate glass, or other similar material. FIG. 1B shows a top perspective view of the filter 100 shown in FIG. 1A. In particular, FIG. 1B shows the filter assembly 101 supporting a filter media 105 that is configured to form pleats 108. The filter media 105 forms a top surface of the filter 100. A side surface 103 may be configured to support the portion of the assembly 101 that supports the filter media 105. During packaging, shipping, and unpacking, a customer may damage the delicate filter media 105 and pleats 108.
A packaging apparatus in accordance with an embodiment is shown in FIG. 2. For example, a packaging apparatus may include an outer shipping carton 205 that is configured to contain a filter wrap having a side wrap 212. A handle 215 may be configured to extend from the side wrap 212. The side wrap may be arranged to contain a filter such as the filter shown in FIGS. 1A-1B. The packaging apparatus may be comprised of any material suitable for packaging, such as, for example cardboard. Packaging apparatus may comprise, for example, 32 ECT “C” flute corrugated board with a kraft outer liner. A side and bottom of packaging apparatus may be formed to have a same thickness.
The filter wrap may be contained inside of the outer shipping carton 205 for shipping. The handle 215 may be used for inserting and removing the filter-containing filter wrap in and from the shipping carton 205. Accordingly, the handle 215 may prevent a customer from reaching into the packaging and puncturing or otherwise damaging the filer media. The handle 215 also may accommodate removal of the filter wrap from the outer shipping carton without requiring that the filter itself be grasped for removal thereof.
FIG. 3A shows a packaging apparatus in accordance with an embodiment. In particular, FIG. 3A shows a filter wrap for wrapping a filter. The filter may have a protective covering 300 such as plastic. The filter wrap may have a side wrap 312. The side wrap 312 may define a slit 314 for receiving a handle 315. In the embodiment shown in FIG. 3A, the handle 315 is formed on a rear wrap 318. A front wrap 320 may define a slit 321, which may be configured to receive the handle 315. A filter may rest on a base 325, which may provide support to a filter contained by the filter wrap. For example, the protective covering 300 may be removed from the filter while the filter rests on the base 325.
The side wrap 312 may extend from a first side of the base 325. The rear wrap 318 may extend from a second side of the base 325 in a direction perpendicular to a direction in which the side wrap 312 extends from the base 325. The front wrap 320 may extend from a fourth side of the base in a direction opposite from the direction in which the rear wrap 318 extends. A third side of the base 325, opposite from the first side, may not have a wrap extending therefrom. Rather, the side wrap 312 may extend a distance that accommodates wrapping of the side wrap 312 over a filter positioned on the base 325, and around the filter to meet the third side of the base 325.
The side wrap 312, rear wrap 318, and front wrap 320 may be configured so that to package a filter, the rear wrap 318 may be positioned to cover the rear and top portions of a filter. The side wrap 312 may then be positioned to cover a first side of the filter, and top of the filter, the handle 315 being passed through the slit 314. Then, the front wrap 320 may be positioned to cover a front and top of the filter, the handle 315 being passed through slit 321.
The wrapped filter may be carried by the handle 315, and may be supported by the base 325 during packaging and unpacking. For example, the handle 315 may used to lift the filter wrap and filter into and out of an outer shipping carton. The filter may rest on the base 325 during unpacking while, for example, packaging materials are removed from the filter prior to installation of the filter into a printing system. The filter wrap may be formed of, for example, cardboard, or similar suitable materials. The filter wrap may comprise material suitable for packaging. For example, the filter wrap may comprise 32 ECT “C” corrugated fiber board. The filter wrap comprise other ECT value boards, e.g., 26 or 44. Further, the filter wrap may comprise B, E, F, and A flutes. The filter wrap may comprise a white liner. The filter wrap may comprise fiberboard.
FIG. 3B shows a packaging apparatus in accordance with an exemplary embodiment. FIG. 3B shows a filter wrap for wrapping a filter. The filter may be wrapped in a protective covering 300, which may be formed of plastic, for example. The filter wrap may include side wraps 312 and 313. The filter wrap may include a front wrap 320 and a rear wrap 318. The rear wrap 318 may form a handle, and the front wrap 321 may define a slit configured for receiving the handle.
A filter may be supported by a base 325. The side wrap 312 may extend from a first side of the base 325. The side wrap 313 may extend from an opposite third side of the base 325. The rear wrap 318 may extend from a second side of the base 325 in a direction perpendicular to the direction in which the side wraps 312 and 313 extend. The front wrap 320 may extend from a fourth side of the base 325 in a direction opposite to the direction in which the rear wrap 318 extends.
The side wraps 312 and 313 may be positioned to cover the first and third sides of the filter. The rear wrap may be positioned to cover a side and top of the filter. Then, the front wrap 320 may be positioned over the filter to cover two opposing sides of the filter and the top of the filter, the handle passing through the slit 321. The wrapped filter may be carried by the handle 315. For example, the filter wrap may be inserted into and/or removed from an outer shipping carton by the way of the handle without damaging filter media.
FIG. 4 shows an unpacking method in accordance with an exemplary embodiment. FIG. 4 shows a method 400 of packaging a filter in a filter wrap as shown in FIG. 3A. At S401, the filter wrap containing a filter may be removed from an outer shipping carton by way of handle 315. When the side wrap 312 is unwrapped, two opposite sides of the filter are exposed.
At S405, a side wrap 312 may be removed from covering a side and top of a filter. At S410, front wrap 320 may be removed from covering a side and top of the filter, the slit in the front wrap 320 sliding over the handle 315 for removal. The slit 314 may slide over the handle 315 as side wrap 312 is unwrapped from covering the filter. The front wrap 318 may be removed from covering a side and top of the filter, the entire filter being exposed thereby. At S415, the protective covering 300 may be removed from the filter while the filter rests on the base. A filter may be packaged using the steps shown in FIG. 4, in a reverse sequence. Further, the filter may rest on the base 325 as the filter protective covering 300 is removed, the base 325 providing support for the filter.
FIG. 5 shows a packaging method in accordance with an exemplary embodiment. FIG. 5 shows a method 500 of packaging a filter in a filter wrap as shown in FIG. 3B. At S501, the filter wrap containing a filter may be removed from an outer shipping carton by way of handle 315.
At S505, a front wrap 320 may be removed to uncover a side and top of the filter. A handle 315 may slide through a slit in the front cover 320. While the wrapped filter is carried, the front wrap 320 is being unwrapped, and while the wrap 320 is removed from the filter and extended as shown at S510, side wraps 312 and 313 may prevent the filter from sliding out of the filter wrap.
At S510, a rear wrap 318 may be removed from the filter, uncovering and exposing a top of the filter and a side of the filter. The handle 315 may be formed on the rear wrap 318. The handle 321 may be configured to pass through a slit 321, the slit 321 being defined by the front wrap 320.
At S515, the filter may be fully exposed, and resting on a base 325. The base 325 may be configured to support the filter. For example, the base 325 may be formed of a sturdy material that prevents the filter from dropping. The filter may be wrapped in a protective covering 300. The protective covering 300 may be removed while the filter rests on the base 325, so that the filter may be supported during removal of the protective covering 300, protecting the filter from damage by surrounding objects. At S515, side wraps 313 and 313 may be removed from the filter. Similarly, front wrap 320 defining the slit 321, and rear wrap 318 having the handle 315 attached thereto are removed from the filter, exposing the filter, which rests on the base 325.
