DETAILED DESCRIPTION OF THE DISCLOSURE
[0019] In aspects, the present disclosure is related to labeling of containers. Specifically, the present disclosure is related to labels for use in a kitchen or other food handling environment where label informational content is frequently changed.
[0020] The present invention is susceptible to embodiments of different forms. There are shown in the drawings, and herein will be described in detail, specific embodiments with the understanding that the present invention is to be considered an exemplification of the principles and is not intended to limit the present invention to that illustrated and described herein.
[0021] FIG. 1 shows a diagram of a prior art storage container 100 with partially removed label 120 on a storage container's surface 110. The partial label 120 shows written text 130 and has left behind adhesive residue 140 on the surface 110.
[0022] FIG. 2 shows an exploded diagram of a reusable label 200. The label 200 includes an information layer 210, a structural layer 220, and an adhesive layer 230, referred to throughout as the first, second, and third layers, respectively. The reusable nature of the label 200 is found in the first layer 210, which is erasable, and, thus, may be reused to identify different contents of whatever container to which the label 200 is attached. The first layer 210 is waterproof but capable of receiving ink, such as that found in dry erase and permanent markers. Additionally, ink that does not smear under water based stress often found in kitchens, such as steam, condensation, and water baths, may also be used. The first layer 210 may be made of a polypropylene film. Additionally, laminates, acrylic coatings, polyester coatings may be used as alternatives to the polypropylene film. In some embodiments, the polypropylene film is an oriented polypropylene film. The first layer 210 provides a smooth surface that can be written on by an erasable marker and later erased without absorbing any of the ink from marker. Thus, the first layer 210 can be marked, washed by hand or a conventional dishwashing machine, and then reused. The second layer 220 provides structural support for the first layer 210. The second layer 220 may be colored to have a strong contrast with an ink intended for application to the first layer 210. For example, the second layer 220 may be white in color to contrast with a black ink marker applied to the first layer 210. The second layer 220 may be waterproof and. In some embodiments, the second layer 220 may be made of a synthetic paper. In some embodiments, the second layer may include a mixture of polypropylene and polyethylene. In some embodiments, the second layer may include polyvinylchloride or polystyrene. The thickness of the second layer 220 may be varied to control the stiffness of the label 200 as would be understood by a person of skill in the art. In some embodiments, non-erasable indicia may be applied to the second layer 220 that will be visible through the first layer 210. In other embodiments, non-erasable indicia may be applied to the first layer 210. The second layer 220 may be tear-resistant, resilient, and not subject to significant dimensional changes due to changes in temperature over a temperature range of about 18 degrees Celsius to about 150 degrees Celsius. In some embodiments, the second layer 220 may have thermal expansion properties selected based on the surface to which the label 200 is to be applied. For example, in an embodiment where the label 200 is designed for application to an HDPE container, the second layer 220 be made of a material with thermal expansion characteristics that are the same or similar to those of HDPE. The similar thermal expansion characteristics of the second layer 220 and the container 100 will reduce the stress between the label 200 and the container 100 that can weaken the adhesive bond between the label 200 and the surface 110. In some embodiments, the second layer 220 may be made of a thinner version of the same material as the container 100. A third layer 230 is made of an adhesive for attaching the label 200 to the surface 110 of the container 100. The adhesive is waterproof and nontoxic at temperatures between 18 degrees Celsius and 150 degrees Celsius. Suitable adhesives may include, but are not limited to an adhesive acrylic blend, an adhesive rubber/acrylic blend, or a synthetic resin.
[0023] FIG. 3A shows a diagram of the second layer 220 and the third layer 230 viewed with the third layer 230 in the foreground. The third layer 230 may include an adhesive perimeter region 310, which is a thickened amount of the same adhesive used throughout the third layer 230. When the label 200 is applied to the container surface 110, the excess adhesive in the adhesive perimeter region 310 is squeezed out toward the ends of the second layer 220. This excess adhesive may extend beyond the perimeter of the second layer 220 and form a seal (e.g. water lock) to prevent water or other liquids from getting between the label 200 and the container surface 110. The excess adhesive extending beyond the perimeter of the second layer 220 may increase adhesion strength and reduce the risk of bacterial growth. FIG. 3B shows a diagram of the second layer 220 and the third layer 230 viewed with the third layer 230 in the foreground but without the adhesive perimeter region 310. While FIG. 3B shows the third layer 230 as not coterminous with the perimeter of the second layer 220, this is exemplary and illustrative only, and the coterminous second and third layers 220, 230 are contemplated.
[0024] FIG. 4 shows a diagram of a labeled storage container 400 with the label 200 affixed to the surface 110 of the storage container 100. The adhesive from the perimeter ring 310 has been squeezed out to form an outside perimeter of adhesive 410 around the label 200. The marker inked words 420 are shown on the label 200.
[0025] FIG. 5 shows a side view of the applied label 200 in FIG. 4. The outside adhesive perimeter 410 is shown to extend past the edge of the second layer 220. The extension distance beyond the edge of the second layer 220 may be varied based on the amount and type of adhesive used and the material properties of the surface 110. By providing a gradual, sloped adhesive edge rather than a sharp cutoff, such as the adhesive layer 230 being coterminous with the second layer 220 at the perimeter, the adhesion strength is increased due to the reduction in the size of the crack or division between the label 200 and the surface 110. Thus, stress concentrators are reduced or eliminated.
[0026] FIG. 6 shows a flow chart of a method 600 for applying the label 200 to the surface 110. In step 610, the label is positioned over surface of container at a desired location. In step 620, force is applied to the center of label to place the label in contact with the container surface 110. In step 630, force is applied against the label and spreading outward from the center to the sides of the label to ensure contact and to force the excess adhesive in the adhesive perimeter region 310 to flow out from the sides of the label and to form the outer adhesive perimeter 410.
[0027] While embodiments in the present disclosure have been described in some detail, according to the preferred embodiments illustrated above, it is not meant to be limiting to modifications such as would be obvious to those skilled in the art.
[0028] The foregoing disclosure and description of the disclosure are illustrative and explanatory thereof, and various changes in the details of the illustrated apparatus and system, and the construction and the method of operation may be made without departing from the spirit of the disclosure.
