These and other features and advantages of the invention will become more apparent with a description of preferred embodiments in reference to the associated drawings.
In an embodiment, a one-piece, plastic-free blister package is contemplated. The package is formed from a one-piece card that may have printed graphics or text on the front and back surfaces of the one-piece card. A blister coating is applied to the back surface of the back side of the one-piece card. The one-piece card is die cut to form a front support card having an open window cut through the front support card and a rear portion connected to the front support card. The rear portion has a back, four sidewalls, and four tabs, so that when folded, a cavity is formed to hold a product. The cavity is sized and configured for holding products such as batteries, an essential oil container, cosmetics, or lip balm, for example. The assembled package is formed by simply folding the front support card over the rear portion folded to form a cavity. Heat and pressure are applied to the package which seals and bonds the front support card to the rear portion. The assembled package encloses the product, which is visible to consumers through the window cut on the front support card, and does not require plastic components such as a separate plastic cover for example.
Embodiments described herein may have several benefits over conventional packages and packaging methods. First, embodiments are free from the use of plastic components which are often used to showcase a product in conventional packaging. Many consumers are environmentally conscientious and may appreciate using plastic-free packaging which may be more advantageous to the environment. Second, embodiments having an open window in the front support card which enables the consumer to “touch and feel” the products they wish to purchase. Third, consumers may appreciate that the packaging encloses the product to prevent tampering with the product. Fourth, as the package is formed from a one-piece card, the package may be assembled with a simple “fold and seal” technique so that the front support card and the rear portion are self-aligned during the bonding process.
The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide a One-piece, Plastic-free Blister Package and Method.
The method involves using a blister packaging process to package a product within the package, wherein the package is made from cardboard or other non-plastic material. It is a single piece of card material with a fold between the front portion and the rear portion of the blister package card.
Cards are printed then coated with a blister coating on the back side. The cards are die cut with a fold configured to the product and the dimensions change for different size products. The card stock can be from 14 point to 28 point blister board depending on the weight of the product. The steps for sealing the one-piece package include placing the card onto a sealing tray on a heat sealer, placing the product in the cavity, folding the front support card over and sealing.
Embodiments described herein include a one-piece paper product that is simply folded over and sealed without need for a separate plastic blister. It can be used for things like batteries, essential oil containers, flea spray, lip balm, etc., in that a window that is slightly smaller than the cylindrical product can be punched out so that the potential buyer can see the product through the window.
