  This application claims the benefit of US Provisional Application No. 60 / 797,508, filed May 4, 2006, entitled "Carton with Venting Openings", the entire contents of which are hereby incorporated by reference. Incorporated.

  The present invention generally relates to a carrier or carton with functions such as vent openings or openings.

  Cartons such as paperboard cartons used for the purpose of holding, transporting or dispensing articles are known. These cartons are usually formed and folded by folding selected creased paperboard carton blanks to cut out some selected areas to achieve the desired functions and properties. Assembled. These functions include tear lines, handles, opening functions, dispensers, and other characteristics. Such an opening function can be formed, for example, on the top panel, side panel, or other panel, or the end of the carton.

  When assembling a carrier or carton from a paperboard carton blank, the opposing ends of the blank are typically attached together with glue or other adhesive to form, for example, the bottom panel of the carrier. An end flap is included on the side of some or all panels and folded inward to close the end of the carton and contain items such as beverage containers therein. These end flaps may contain an opening function or a dispensing function or may include a handle for carrying the carton.

  The present invention generally relates to a carton with a venting function formed in a panel or end wall. These vent openings are formed, for example, at one end of the enclosed carton, or at both ends of the enclosed carton, overlapping the panel from the end, or two or more adjacent It may be an opening that overlaps through the panels or is formed in one panel. The vent opening may be a single opening formed in any end panel, or multiple openings formed in any end or panel, or a combination thereof. In general, vent openings allow temperature exchange to “freeze”, “quick freeze”, “heat” the product in the carton or, in general, as opposed to a fully sealed carton that does not contain such an opening. An opening or opening is provided for exchanging air between the interior and exterior of the carton for maintenance and promotion. Such openings can provide accelerated temperature exchange.

  Ventilation openings may be oval, oval, circular, square, triangular, rectangular, quadrilateral, arcuate, star shaped, or any trademark or other design, trademark or other text, or any other Any shape such as shape or design may be used. For example, the carton detailed herein is a yogurt product with the name of the manufacturer, such as Dannon®, embossed or cut through a termination flap that forms part of the exit end. You may make it seal the circular container which accommodates. The openings that form all or part of the word Dannon® can be formed on either end, on any end flap, or on any panel. As another example, if the carton detailed herein is sized to hold a round can containing a beverage therein, through one of the end panel flaps, Coca Cola® And may be embossed or cut. For example, if an opening of any size or design or letter to identify the manufacturer of the product is included as an opening in the panel or end flap, the opening is generally a tear line used to form the opening in the container Along and / or between and / or substantially adjacent thereto. An opening or opening or letter opening may be in the side panel end flap to separate the tear line into discrete or non-continuous tear lines that are spaced apart by the opening, hole, or opening. An oval or elliptical opening is shown in the first side panel end flap at the outlet end, one opening is shown along the tear line. A tear line enters the first side panel from the first side panel end flap and extends across it, and also enters the top panel, extends across it, and into the second side panel. Enters, extends across and continues into the end flap of the second side panel. The tear line is shown as continuing to the other side of the opening toward the peripheral region of the first side panel end flap.

  The present invention can be combined with other carton functions, such as an opening function formed for dispensing articles from a carton. The opening shown is generally formed in the top of the carton and can include a section of each side panel and a portion of the exit end. The opening is generally formed by separating the tear line to form the remaining carton portion and the removable or hinged dispenser flap portion. The side panel end flap portion remaining after the opening is formed provides the encapsulated (encapsulated) carton with a maintenance function to keep the article therein prior to dispensing.

  To dispense from the formed carton, the dispenser flap is typically separated along the tear line by first using a finger flap (shown here in the top panel of the figure) to open the opening Form. An opening is formed along a cut line in a part of the top panel, the side panel, and the side panel end flap. Generally, when the opening is formed by separating the top panel end flap by a tear line, the entire top panel end flap is removed. The bottom panel end flaps and the rest of the side panel end flaps that were not removed due to the formation of the opening remain and form part or all of the maintenance function that maintains the articles in the carton prior to the intended dispensing To do.

  The present invention can be used, for example, to distribute articles containing products such as food and beverages. These articles also include beverage containers such as cans, bottles, and PET containers, and other containers of cylindrical, cuboid, parallelepiped, or any other shape such as those used in food packaging. Can do.
