  • liquid or flowable products such as juice, milk, syrup, wine, sauces, oils, soup, broth, sugar, salt, confectionary pieces, birdseed, food or non-food particles, pellets, or liquids, skin care products, jewelry beads, BB shot, etc.
  • Retail packaging for flowable solid and/or liquid products is commercially available in many styles and sizes e.g. 8-8 ounce single serve juice boxes, stand up pouches (StfPs) containing alcoholic or non-alcoholic beverages, retort and aseptic boxes for a range of food items such as broths, soups, milk, fruit or vegetable juices or purees, etc.
  • Both food and nonfood retail packages are available in a wide variety of sizes and shapes.
  • metal cans made from aluminum, steel and other materials are well known.
  • Plastic and glass jars, bottles and tubs as well as plastic and paper bags including pouches, envelopes, stick packages, etc. are ail ubiquitous in modern commerce. Suitable packaging, e.g.
  • containers may protect their contents from contact or exposure to unwanted materials such as dirt, dust, microbes, insects, air, moisture, sunlight, etc.
  • materials used in constructing packaging and especially for a product such as a food (including drink) or drug should resist migration of chemicals between the product and the package materials. Examples of prior art packaging include U.S. Patent Nos, 1 ,157,462; and 3,314,210.

  • a retail bag ⁇ in ⁇ box package having a flowabie product contained in a thermoplastic bag which is inserted in or encased within an outer relatively rigid box or carton is provided.
  • the box or carton may be constructed from a rigid or semi-rigid plastic or paperboard and has (I) a flat bottom panel, an opposing top panel, and a self-supporting, upstanding wall connecting the bottom and top panels, and (ii) an access port through the box for inserting a rigid implement, such as a drinking straw or other spout tap therethrough to puncture trie bag and withdraw the flowabie product from inside the bag.
  • the bag is a retail sized, flexible thermoplastic bag (capacity ⁇ 1 liter) attached to an interior surface of the box proximate the access port.
  • the bag-in-box package of the present invention is hand-held, e.g., designed to be used while being held in one hand by the consumer.
  • a important aspect of the present invention is that the flowabie product occupies less than 100% of the available volume of the bag and the remaining available head-space volume above the product is evacuated or collapsed in order to prevent spillage or leakage of product from the straw or spout when the bag is punctured.
  • the consumer When a bag is pierced with a straw or other rigid implement, the consumer must manually hold the box to insert the straw.
  • the box and bag are squeezed together by ones fingers creating a positive pressure within the bag. if the bag is completely filled with product or when ther is a gas-filled head-space above the product In a less than a completely filled bag, the pressure inside the bag causes liquid product to rapidly exit through the straw and spill out onto the consumer.
  • the flowable product occupies at most about 87%, 83%, 75%, 87% or 58% of the available volume of the bag and the remaining head-space volume above the product is void of any injected gas and product, i these embodiments, the fiowable product occupies at least about 33%, 42%, or 50% of the available volume of the bag.
  • Th inventive package is suitable for packaging small flowable articles or products (including either solids and/or liquids) of a size typical for consumer or individual use.
  • products which may be packaged in accordance with the present invention include without limitation: milk, fruit or vegetable juices or purees such as: apple, apricot, black currant, cherry, grape, peach, pear, pineapple, or pomegranat juice; citrus juices like orange, grapefruit, and lemon juice; carrot juice; tomato Juice of puree; non-alcoholic or alcoholic drinks such as water, flavored water, juice, tea, or wine; honey; syrups for sweetening foods e.g. pancake syrup; syrups for flavoring beverages e.g.

  • attachment means such as adhesive disposed proximate to an access port to seal the bag thereto.
  • the consumer or retail sized bag-in- box may be shipped to retail outlets and stored or displayed for sale on store shelves, A consumer will access the flowabie or liquid product held therein by inserting a dispensing fitment, e.g., straw through the access port thereby piercing the bag film which is held in place against the box adjacent to the access port e.g, by adhesive, This helps to ensure a non-leaking connection.
  • the access port will be located on the uppermost or top surface of th box or rigid container, it Is contemplated that this port may be located on other surfaces including front, back or side wall surfaces at any desired location whether proximate the to or not. In some embodiments in may be advantageous to have a bottom access port to permit use of a gravity feed dispenser e.g. for hand iotion, soap and the like.
  • the bag and bo need to interact.
  • the bag idealfy is attached to a top lid of the box or carton. This ensures the bag stays at the top of the carton and is not pushed down away from the top with the applied force. If the bag is not securely attached to the top lid of the box, the pressure created, e.g. from a straw, tends to force liquid contents out which creates a mess.
  • a registered printed wax coating o wax coated piastic film may provide good adhesion of the hag to the box and advantageously melt attaches at a very low temperature.
  • Another option for adhesion of bag to box is be to use hot glue or a PSA type material to adhere the pouch to the carton.
  • the best location for the hot glue is around the perimeter of the access port hole (creating a ring) without going into the area to be punctured.
  • Glue in the area to be punctured may undesirably increase the force needed to puncture the pouch.
  • Alternative attachment means include glue patterns of e.g., two or more dots or stripes of glue on either side of the hole. Patterns that do not work well include attaching the pouch to the carton far away from the punctured area (as in side flaps) or on only one side of the hole. This causes the bag to pull away from the box or deflects the path of the straw in straw plus drink box embodiments.
  • the fitment may be applied to either the box top or to the face of the inner bag with a die cut or perforated area of the bo for the fitment to slot into or be pulled through respectively.
  • a top lid on the box In order to dispense a liquid without the top lid popping off, a top lid on the box must either be attached to the bag or the interior wall of the box.
  • Puncturing devices such as straws, pumps, or sprayers may use a sharp end to puncture the bag.
  • the device would need to adhere to the outside of the box. This may be accomplished by various means including e.g. the use of a liner on the top of the box that would expose a PSA when removed.
  • Fitments may also be placed on the face of the bag and not in the sealed area.
  • the bag film may be die cut to form a hole and a fitment sealed over the hole or alternatively a suitable fitment that cuts into the film may be employed.
  • Fitments may be placed in the seal area and protrude from the top of the box.
  • a fitment attached washer may be used to connect to both bag and box with opposing sides of the washer being sealed by fusion or adhesive to bag and box, respectively.

Abstract

La présente invention a pour objet un emballage de caisse-outre ayant un produit liquide contenu dans un sac thermoplastique qui est inséré, ou encaissé, dans une boîte ou un carton externe relativement rigide. La boîte ou le carton peut être construite, ou construit, à partir d'un plastique rigide ou semi-rigide ou d'un carton-pâte et comporte : (i) un panneau inférieur plat, un panneau supérieur opposé et une paroi verticale, autoporteuse, reliant les panneaux inférieur et supérieur; et (ii) un orifice d'accès à travers la boîte destiné à insérer un outil rigide, tel qu'une paille ou un autre bec verseur/robinet à travers ce dernier pour percer le sac et retirer le produit liquide depuis l'intérieur du sac. Le produit liquide occupe moins de 100 % du volume disponible du sac et le volume d'espace libre disponible restant au-dessus du produit est vidé ou plié pour empêcher toute perte ou fuite du produit depuis la paille ou le bec verseur lorsque le sac est perforé.
