Definitions

  • This invention relates to containers, marking of containers, and methods of producing containers.
  • a label may identify the food contained in the container, as well as provide information about freshness, quality assurance, and safety of the contained food. In this manner, cross contamination is inhibited, and the expected shelf life of the food before expiration may be determined by food preparers and health department inspectors.
  • a health department may require that the label be renewed periodically, and even as frequently as each day.
  • Relabeling means removing the expired marked label and replacing it with a new marked label.
  • Labels known in the art which are used for this process, can be difficult to remove from the container, and become unreadable in high moisture areas, such as walk-in food coolers and freezers. Labels known in the art are difficult to remove, and may leave an adhesive residue on the container that is considered a violation of state health codes.
  • the labeling system of the present invention may help resolve these problems by permanently embedding into the container and providing spaces to record information about the food with an erasable marker.
  • Labels known in the art typically utilize an adhesive that sticks to the container.
  • the label must be peeled off for every change in container content or after a predetermined period. This leaves adhesive on the container, which can contain bacteria. Additionally, the labels known in the art should receive a single marking, without crossing out the prior marking and/or writing on the edges of the label, which may lead to confusion regarding the information.
  • the present invention is a container having a label that is embedded in the container.
  • the container is sufficiently transparent to allow the indicia of the label to be ascertained through a wall of the container.
  • the exterior wall of the container may be written upon with a marker that leaves marks that are erasable from the exterior of the container. A method of producing the container is also described. Description of the Drawings
  • FIG. 1 is a perspective view of a container according to a preferred embodiment of the invention.
  • Fig. 2 demonstrates a process of preparing a prepared laminated label for the container.
  • Fig. 3 is a side, sectioned view of a prepared laminated label.
  • Fig. 4 demonstrates a mold for forming a container according to a preferred embodiment of the invention.
  • Fig. 5 is a partial view of the prepared laminated label in the mold.
  • FIG. 6 is a partial sectioned view of a container according to a preferred embodiment of the invention showing the label embedded in the walls of the container.
  • Fig. 7A shows a step of a marker applying erasable indicia on an exterior wall of the container and over the embedded label.
  • Fig. 7B shows a step of a erasing the erasable indicia from the exterior wall of the container.
  • Fig. 7C shows a step of a marker applying erasable indicia on an exterior wall of the container and over the embedded label after the erasable indicia is erased.
  • FIG. 8 illustrates a frontal view of an exemplary label having a plurality of spaces for identifying contents of the container.
  • a label 2 is permanently embedded in a container 4, which may be a food container.
  • the label may be reused for identifying container contents, and the conditions, age, or other information about the container contents.
  • the label remains integrated into the container, such that repetitive removal and manipulation of the label relative to the container for remarking the label is not necessary.
  • the label records parameters and information about the contents of the container without requiring manipulation of the label or remarking the same label by direct contact with a marker.
  • the label may also receive a removable or erasable mark through an erasable marker.
  • the marks may include at least one parameter containing information about container content. Because of the permanent attachment of the label and the container, and the capacity to erase and rewrite indicia on the label, the need for the removable labels known in the art is negated, or at least minimized.
  • the container 4 may be a plastic food container, and may be used to store food in a cooler.
  • the label 2 may include a plurality of lines or spaces that receive erasable marks from a marker. At least one parameter marked on the lines or spaces may include information pertinent to the identification, shelf life, and preparation time for the food, and also include a preparer identification.
  • the parameter includes information about the container content, including, expiration information, container content, and preparer information. Because the label is permanently embedded into the container and the marks on the label are erasable, the label does not have to be removed daily for marking new information thereto. This capacity to repetitively use the label without physically detaching it from the container may help reduce costs and labor associated with replacing the label in every instance the container is changed.
  • the label may embed between an inner wall 10 and an outer wall 12 of the container 4.
  • the integration of the label into the container may help eliminate the need to repetitively replace the label after use, or after new container content is stored in the container.
  • the label may be configured to receive erasable markings from a marker, such as a nonpermanent ink marker, or wax marker such as a grease pencil, also known as a wax pencil, china marker or chinagraph pencil.
  • a marker such as a nonpermanent ink marker, or wax marker such as a grease pencil, also known as a wax pencil, china marker or chinagraph pencil.
  • the use of erasable marking further enhances the use of the label by providing a clear space every time new markings must be written.
  • the label may include a plurality of spaces for marking at least one parameter pertinent to the container contents.
  • the pluralities of spaces are configured to receive marking for at least one parameter.
  • the parameter may include time and dates that can show the expiration times for the container content.
  • a week's worth of parameters may be marked into the spaces. After the week is completed, the marks may be removed by washing them off with a liquid or rubbing them off, depending upon the marking device that is used. Thereafter, a subsequent week, with possibly different container contents, may be stored and have the parameters identified using the same label. This is accomplished without repetitively replacing labels or remarking the same printed label.
  • At least one daily space identifies a date the container content is placed in said container; a content identification space identifies the container content, a preparation parameter space identifies a date and a time of preparation of the container content, a shelf life space identifies a shelf life for the container contents; an expiration space identifies an expiration date for the container content; and a preparer identification space identifies a preparer of the container content.
  • FIG. 1 illustrates detailed perspective views of an exemplary labeling system, with an exemplary label embedded into the container, in accordance with an embodiment of the present invention.
  • a label 2 is joined with a container 4.
  • the label and the container may be permanently joined together. In this manner, the label may be reused for identifying and describing different container contents every time the container contents are changed, or after predetermined time duration has passed.
  • the label 2 may receive erasable marks 6 from an erasable marker 8.
  • the marks may include at least one parameter containing information about container contents. Because of the permanent embedding of the label 2 in the container 4, and the capacity to erase and rewrite marks on the label, the need for adhesive backed or pressure sensitive labels known in the art is negated, or at least minimized.
  • the outer wall 12 of the container 4 is preferred to have a smooth, flat surface that will receive readable marks 6 from the marker 8 that may also be erased.
  • the container is preferred to be formed of a material that will display the markings without smearing when exposed to wet environments, such as those environments that occur in kitchens and coolers.
  • Grease pencils tend to resist exposure to water, and marks from a grease pencil are received and displayed by most plastics, including thermoplastics, and including polycarbonate. Grease pencil marks may be removed from most smooth plastic surfaces by rubbing with a cloth.
  • Materials for the label may include, without limitation, paper, polymer, textile, metal.
  • the label is formed of a thermoplastic, such as LEXAN®.
  • the label may be formed in layers, so that a layer of thermoplastic is over a layer that forms a substrate for receiving the printed indicia.
  • Other layers may be provided, such as a layer behind the printing receiving layer or layers, or other protective layers.
  • the label 2 may be a planar member.
  • the label may have various shapes, including, without limitation, rectangle, square, circle, oval, and pyramid.
  • the indicia are permanently printed or formed on the label, and are particularly permanent after embedding the label between container walls.
  • the label may embed between an inner portion or inner wall 10 and an outer portion or outer wall 12 of the container.
  • the integration of the label into the container may help eliminate the need to repetitively replace the label after a period of time or after each new container content is stored in the container.
  • the label may record at least one parameter about the container contents for a period of time, such as one week.
  • the container may include a plastic food container used to store food in a cooler.
  • the plastic food container is formed of a material that cures to be sufficiently transparent to read the label through a layer or wall of the material.
  • Preferred materials for forming the container are thermoplastics, such as polycarbonate.
  • other suitable materials may include, without limitation, NSF plastics, polyurethane, polyethylene, clear polymers and other materials that may be formed by injection molding and are sufficiently transparent to meet the goals of the invention as described herein.
  • the label may include a plurality of lines or spaces such as those shown in the drawings over which erasable marks from a marker may be applied to the container.
  • At least one parameter marked on the spaces may include information pertinent to the identification, shelf life, and preparation time for the food, and also include a preparer identification.
  • the pluralities of spaces or lines are configured to receive marking for parameters.
  • the parameters include time and dates that can show the expiration times for the container content.
  • a week's worth of parameters regarding the contents may be marked on the container 4 over the label spaces.
  • the marks 6 may be removed by washing them off with a liquid or rubbed off with a cloth 14, depending upon the type of marker used.
  • Fig. 7B Thereafter, a subsequent week, with possibly different container contents, may be stored and have the parameters identified using the same label 2 by applying marks 6 with an erasable marker 8. This is accomplished without repetitively replacing labels or remarking the same printed label.
  • the at least one parameter includes information about the container in a time prior or weekly period. Because of the greater time period and other information marked into the spaces, the label does not have to be removed periodically for marking new information thereto. This capacity to repetitively use the label without physically detaching it from the container may help reduce costs and labor associated with replacing the label in every instance the container is changed.
  • FIG. 8 illustrates a frontal view of an exemplary label having a plurality of spaces for identifying contents of the container, in accordance with an embodiment of the present invention.
  • a label 2 may include a planar member configured to locate marks from a marker, and display marks formed on an at least partially transparent container.

  • useful markers may include a grease pencil, erasable ink, a crayon, chalk, detachable text and numbers, and any partially removable or erasable mark.
  • erasable marking further enhances the use of the label by providing a clear space every time new markings must be written.
  • the erasable marking forms temporary indicia on the container, which may be erased, and new temporary indicia applied by the erasable marker.
  • the plurality of spaces comprises at least one parameter pertinent to the container contents.
  • the spaces may provide an area over which to mark the time, week, duration, contents, and food preparer's information.
  • a week's worth of parameters may be marked into the spaces. After the week is completed, the marks may be removed by washing or rubbing, depending upon the type of non-permanent marker used. Thereafter, a subsequent week, with possibly different container contents, may be stored and have the parameters identified using the same label. However, in other embodiments, the parameters may cover anywhere from a day, a month, or longer.
