Definitions
- the invention is directed to a packaging device and method for absorbing moisture, steam, or condensation through the use of embedded carbon-containing substances. 5
- a problem with packaging of goods arises when the packaging creates an environment which negatively affects the packaged content.
- One example is the packaging of fine art or other materials which decay or go bad when moisture or a o humid condition is trapped.
- Another example is the negative effect on packaged food due to steam vapor in a container such as a paper box or bag.
- the steam that emanates from a hot food such as pizza, french fries, etc. forms condensation that settles within the box or bag, making the pizza or french fries soggy or spongelike.
- the packaging is typically a box constructed of either corrugated boxboard, or containerboard.
- Corrugated boxboard is made by gluing an accordion-like sheet of paper (corrugated medium) in between two sheets of linerboard.
- Contamerboard or what is also called 'clay kraft back' is a paperboard that does not have any corrugated layer. Contamerboard is commonly used for forming boxes such as a shoe box.
- the condensation that settles on the inside bottom surface of the pizza box is absorbed by the pizza dough by the time the pizza is transported to a place where it can be consumed.
- the Kraft Paper commonly used as grocery bags for temporarily housing other hot food such as french fries, fried chicken, etc. also cannot absorb the vapor from the hot food. The trapped vapor renders the french fries soggy. Accordingly, it is desirous to have a packaging device and method capable of absorbing moisture, steam, or condensation.
- a container for housing food comprising paper having carbon additives for absorbing moisture emanating from the food, wherein the carbon additives include one of charcoal, activated charcoal and activated carbon, wherein the paper is one of a contamerboard, a linerboard, and a corrugated medium.
- the container preferably a corrugated boxboard, includes a plurality of sheets or linerboards, and the carbon additives are embedded in at least one of the plurality of sheets or linerboards, wherein the sheets of paper are made from a mixture of pulp, water, and the carbon additives.
- one, two, or three of the plurality of sheets is/are selectively embedded with the carbon additives.
- one of the plurality of sheets is corrugated and another sheet is perforated.
- a method is also provided for absorbing moisture from food within a container comprising; embedding carbon additives within paper, and forming the container using the paper.
- the carbon additives include charcoal, activated charcoal and activated carbon.
- the paper is one of a linerboard, a containerboard, and a corrugated medium.
- the paper includes a plurality of sheets, each sheet formed from a plurality of layers, and the carbon additives are embedded in at least one of the plurality of sheets.
- the sheets of paper are made from a mixture of pulp, water, and the carbon additives, wherein one, two or three of the plurality of sheets are embedded with the carbon additives.
- the plurality of sheets include an inner sheet and a corrugated sheet, the inner sheet having perforations and the corrugated sheet having the embedded carbon additives.
- a process for manufacturing a container for storing food comprising; forming layers of paper with embedded carbon additives by mixing pulp, water, and the carbon additives; and forming a boxboard with a plurality of sheets of linerboards of the paper to house the food, wherein the step of forming a box includes using a plurality of layers of paper forming sheets or linerboards, including at least an inner linerboard and an outer linerboard.
- the process further including adding perforations to the inner linerboard and corrugating one of the plurality of sheets of paper.
- Figure 1 shows a paper box in an opened configuration according to the present invention
- Figure 2 shows a sideview of the paper box
- Figure 3 shows a cross-sectional view of a corrugated medium in a boxboard.
- the invention is directed to packaging product for housing goods.
- the packaging product is preferably made of paperboard, linerboard, or containerboard having charcoal, activated charcoal, or activated carbon as an additive for absorbing moisture, vapor, or condensation (hereinafter referred to as "Coalboard”).
- Charcoal, activated charcoal, carbon, or substances mostly comprised of carbon are used as additives because of their superior absorbent characteristics, partly due to their extremely vast surface area.
- the charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon is mixed with the wood fiber (more commonly known as pulp) in the blend chest.
- the linerboard with the embedded charcoal is disposed within a packaging container which is perforated on the interior side to enable steam vapor or humidity to enter into the corrugated medium.
- a boxboard is made of containerboard with embedded charcoal, activated charcoal or substances mostly comprised of carbon.
- Figure 1 shows a pizza box made of Coalboard according to the present invention.
- the steam vapor that is emitted from the pizza would be drawn through the perforations and be absorbed by the charcoal. It is readily apparent that pizza is only one example of packaged food that would benefit from the vapor absorbing qualities of CoalBoard. Although this is one embodiment of the present invention, it is not the exclusive embodiment.
- all three sheets of the boxboard 1, which comprises exterior linerboard 3, interior linerboard 5, and corrugated medium 4 are embedded with charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon.
- the interior linerboard 5 that faces the food product includes perforations 2 to enable the steam vapor generated from the hot food to enter into the corrugated medium 4.
- two sheets of the boxboard 1, preferably interior linerboard 5, and corrugated medium 4 are embedded with charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon as an additive.
- the interior linerboard 5 facing the food product is preferably perforated 2 to enable the steam vapor generated from the hot food to enter into the corrugation 4.
- the exterior linerboard 3, and corrugated medium 4 are embedded with charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon as an embedded additive.
- the interior linerboard 5 facing the food product would be perforated 2 to enable the steam vapor generated from the hot food to enter into the corrugation 4.
- one sheet of the boxboard 1, preferably the interior linerboard 5 is embedded with charcoal, activated charcoal, carbon, or substances mostly comprised of carbon as an embedded additive.
- the interior linerboard 5 facing the food product would be perforated 2 to enable the steam vapor generated from the hot food to enter into the corrugation 4.
- the exterior linerboard 3 is the only sheet having charcoal, activated charcoal, carbon, or substances mostly comprised of carbon as an embedded additive.
- the interior linerboard 5 facing the food product would be perforated 2 to enable the steam vapor to enter into the corrugation 4.
- the corrugated medium 4 is the sheet having charcoal, activated charcoal, carbon, or substances mostly comprised of carbon as an embedded additive.
- the interior linerboard 5 facing the food product would be perforated 2 to enable the steam vapor generated from the hot food to enter into the corrugation 4.
- the boxboard is made from containerboard having charcoal, activated charcoal, carbon, or substances mostly comprised of carbon as an embedded additive.
- the boxboard does not include a corrugated medium.
- a number of processes that can be used to introduce charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon into paper are a number of processes that can be used to introduce charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon into paper.
- One exemplary process is by blade coating, which is a method of coating paper and paperboard using a flexible blade to control the amount of coating applied to the paper. Blade-coating can take place either on a papermaking machine or on an off- machine coater.
- the paper may be coated on one side (CIS) or both sides (C2S), or between layers of paper as described in the above embodiments.
- Off-machine coating refers to coating paper after it comes off the papermaking machine rather than while it is still on the machine.
- an off-machine coater is used to add one or more layer of coating of the carbon material to the paper.
- Other known processes such as bath coating or surface siezing coating may also be used to mix or coat the carbon material onto the paper.
