As used herein, relational terms, such as “first” and “second” and the like, may be used solely to distinguish one entity or element from another entity or element without necessarily requiring or implying any physical or logical relationship or order between such entities or elements.
In general, the invention described herein relates to treated substrates which can include but are not limited to treated cloths, wet wipes, sanitary wipes, makeup remover wipes, baby wipes, refreshing wipes, and household cleaning wipes among others known in the arts. These wipes 10 may be distributed within dispensers 600 positioned in public and retail locations, or in discreet containers for personal use, however, industrial use also further contemplated. Currently, the publicly placed dispensers 600 and personal containers may contain advertising material thereon, while the individual wipes have little markings or identifiers. While ink is commonly printed on substrates, the wet nature of the treated substrates poses numerous problems for the printing process. As used herein, the term “substrate” refers to the material the ink is printed on. This printed substrate can then be partitioned into wipes as described herein.
In an embodiment, treated substrate 100 has printed graphics 110 disposed thereon as illustrated in
The term “graphic” When used with reference to printing includes, but is not limited to, any type of design, mark, figure, picture, identification code, words, patterns or instructions. In an alternative embodiment, both sides of the substrate may be printed with different images.
In one aspect, the treated substrate 100 can be used to communicate with the consumer or end-user of the wet wipe 10. Particularly useful messages to communicate to the consumer are the instructions for the use of the product and a message to indicate that the stack of wipes is nearly finished.
In one embodiment, the substrate 100 can be treated with a composition including but not limited to cleaning compositions, wellness compositions, facial-care compositions, sanitizing compositions, disinfecting compositions, etc. The composition can also be applied uniformly or non-uniformly to the surfaces of the substrate. By non-uniform, it is meant that for example the amount, pattern of distribution of the composition can vary over the surface of the substrate.
The substrate 100 can contain an active agent-containing composition that contains an active agent to assist with the use of the wipe. The active agent-containing composition can be included with the nonwoven substrate to provide cleaning properties, disinfectant properties, deodorizing properties, moisturizing properties fragrance properties, etc. An active agent-containing composition that provides cleaning properties can be referred to as a cleaning composition. An active agent-containing composition that provides disinfectant properties can be referred to as a disinfectant composition. Additional compositions containing the various active agents can be referred to as, for example, abrasive compositions, moisturizing compositions, deodorizing compositions, etc. The active agent can be a surfactant, organic solvent, disinfectant, antibacterial agent, bacteriostat, pH adjuster, colorant, viscosity bodying agent, abrasive, moisturizer, perfume, deodorizer, or mixture thereof.
In embodiments, each wipe may be dispensed for personal or public use. For example, for personal use, a simple container having a dispenser 600 on top may contain any reasonable number of wipes 10 therein such that the container may be easily stored in the user's home. Further, the wipes 10 may be dispensed utilizing a dispenser 600 in a public environment, as shown in
In an embodiment, the treated substrate 100 may be adapted for electronic display cleansing as well as surface cleansing as known in the arts.
The process described herein results in a treated substrate 100 having graphics 110 printed thereon. The treated substrate 100, as a result of the process, can be utilized in the domestic or industrial setting. Graphics 110 may be comprised of ink using four-color printing (Cyan, Magenta, Yellow, and Black) such that photograph quality prints may be achieved. Inks may be water based as known in the arts. In general, the process may be delineated into five steps comprising; printing, drying, perforating with registration (e.g., perforating at predetermined internals such that the printed material is fully present on each sheet), cutting, and rolling.
Printing should ideally be performed in a clean-room environment, which has preferentially been cleaned or purified by class 100,000 or ISO8 clean room standards. This environment is recommended as raw materials are open during the printing process which may get polluted, thus tampering with the final product. Printing is performed on an entire roll of substrate.
In a preferred embodiment, the maximum width of printable fabric is 1.16 meters.
In an embodiment and in reference to
Different or identical materials may be placed around the impression cylinders circumference which should be selected to maximize the efficiency of the process (e.g., the circumference can be divided by the length of each wipe). For example, if production of the wipe cabs for 6 CM wipe length, and 10 designs are needed, the impression cylinder circumference should be 60 CM, with every 6 CM having new art for maximum efficiency.
Drying is the second step in the five-step process. The ink may be water-based, water-insoluble, BZK, other common sanitizers, or alcohol based. The drying machine is in communication with the printing apparatus and perforation machine.
In an embodiment, and in reference to
In an embodiment, a positioning system 500, including a processor 505 a is pre-loaded with designs and can identify graphics by light sensation IC. A color tracking system within the optical sensor 300 tracks the colors using color tracking element 310 to ensure registration of the graphic 110 is maintained. The processor includes instructions for steps in the various embodiments presented herein.
The process can be modified after the printing step wherein wipes are individually cut and folded. Individually cut and folded wipes may be useful for retail sale. Further, a roll production method is disclosed, wherein wipes are not cut and folded. Each unique process is described herein.
In an embodiment, the large roll is automatically sent to cutting components pre-set to cut multiple rolls. The multiple roles are then re-rolled into tight individual rollers to be sent to the wetting step in the process.
The process for retail sale utilizes a 6 in 1 machine which comprises the steps of printing, drying, folding, cutting, watering and packaging.
The folding process as defined herein relates to the folding of individual wipes 100, rather than a large perforated roll. Folding, as defined herein, refers to folding a width of the wipe. Folding may be used for retail sale as specific folding configurations may be used to allow the user to easily receive a single wipe 100 from a dispenser. As a single roll of printed wipe 100 is rolled out of the printing apparatus, a folding machine is positioned between the printer and a cutting cylinder. The wipes are rolled into a Z-configuration and then folded once more in half. The Z fold is a non-inter folded format as each wipe is not folded within an adjacent. In alternate embodiments, a interfold, cross-fold, C hold, J-fold, or combinations thereof as known in the arts may be utilized.
In an embodiment, and related to the registration process in retail sale's production, an optical scanner 300 and a color tracking element 310 may be used to register graphics on the wipes. In this manner, after the wipe 10 is folded, the sensor recognizes the colors on the graphics 110 of the wipes 10 and controls the moving speed of the belt.
Cutting refers to cutting the overall length of the wipe. After the wipes are folded, two sets of cylinders are configured to cut the length of the wipe. In an embodiment, a first set of cylinders ensures the axial orientation of the roll is proper in relation to the second set of cylinders. Preferentially, the roll is parallel with the second set of cylinders. The second set of cylinders has a cutting member along its height. As the cylinder rotates, the cutting member separates the roll at predetermined intervals. The circumference of the second set of cylinders determines the length of the wipes. In an embodiment, a second cylinder circumference of 6 CM performs a cut every 6 CM on the wipe.
In another embodiment wherein a spunlaced substrate 100 is used, the position and speed of one or more cylinders may need to be adjusted at predetermined intervals due to the variable nature of the spunlaced material.
Next, the cut wipes are sent by a belt driven system to a watering machine. The wipes are wetted with a predetermined composition. Once the wipes are sufficiently wet, they are sent directly to a packing machine as known in the arts.
