Abstract: A vented pouch arrangement is described which comprises: first and second opposed panel sections; a base gusset member; and, a gas filter arrangement oriented in one of the panel sections. The gusset member is preferably oriented between the panel sections; along ends thereof, to form a base by which the arrangement can be stood up during use. Preferably, the arrangement is provided with a rib and trough closure arrangement extending there across. In this manner, opening and reclosing the bag construction, for access to material therein, is facilitated. A method for formation of such a pouch arrangement, and methods of use, are also described.

Abstract: A bag construction includes first and second opposed panel sections. Each of the panel sections have first and second opposite side edges. The panel sections are secured to one another along at least a portion of the first and second opposite side edges by first and second side seals, to define a bag construction interior. The first and second side seals each have an inner edge portion adjacent to the bag construction interior. The first side seal inner edge portion has at least one non-linear edge section extending over a part of the first side seal inner edge portion. The non-linear edge may include an edge with a plurality of spaced inwardly directed projections, or an edge with curved portions, or an undulated edge. The seals may be used in a variety of packaging arrangements, and help to provide an arrangement which will stand upright when filled or at least partially filled with material.

Abstract: A bag construction for use to distribute flowable material is provided. The bag construction generally includes first and second panels or panel sections oriented juxtaposed to one another. In one end of the bag construction, a base gusset is provided between the panels. The base gusset includes apertures therein, for distribution of flowable materials. In preferred embodiments, a rib-and-trough closure arrangement is provided so that the pouch construction can be selectively closed to inhibit distribution of material, when desired. Methods of preparing such arrangements and methods of use are provided.

Abstract: A method for the packaging of coffee in a pouch arrangement having first and second opposed panel sections, a base gusset member, a rib and trough closure arrangement constructed and arranged for selective closure of the pouch arrangement, and a gas filter arrangement oriented in one of the panel sections. The method includes filling the pouch arrangement with coffee to a first level no greater than the rib and trough closure arrangement and sealing the pouch.

Abstract: A bag construction for use to distribute flowable material is provided. The bag construction generally includes first and second panels or panel sections oriented juxtaposed to one another. In one end of the bag construction, a base gusset is provided between the panels. The base gusset includes apertures therein, for distribution of flowable materials. In preferred embodiments, a rib-and-trough closure arrangement is provided so that the pouch construction can be selectively closed to inhibit distribution of material, when desired. Methods of preparing such arrangements and methods of use are provided.

Abstract: An improved flexible envelope for use as a mailing pouch or evidence preservation package. The envelope is constructed of a metalized polyester material which is characterized by an incision in a wall of said envelope which is sealed by a pressure sensitive adhesively sealed flap. After the flap is folded over and sealed, the user may open the envelope without the assistance of a knife or scissors due to notches at either end of the line of incision which initiate and guide the tearing of the flap. Any attempt to remove or tear open the sealed flap produces tamper evident markings thereon.

Abstract: A receivable bag arrangement is provided. The bag arrangement includes an internal resealing arrangement utilizable to reseal the bag closed, after it has been used. In a typical arrangement, the resealing mechanism is enclosed within a heat sealed outer periphery. An arrangement is provided, to facilitate tearing open the arrangement by hand. This arrangement includes use of a reinforced tab region immediately adjacent a tear region having a gap portion. The tear region having greater perpencity to tear there across then the reinforced tab region.

Abstract: A bag construction is provided. In the preferred embodiment, the bag construction or arrangement comprises first and second side panels, and first and second edge gusset members. The gusset members are peelable from between the side panels; peeling being facilitated by positioning of end tab extensions at both ends of each gusset member. In a preferred embodiment, both side gusset members comprise a gas-permeable material of sufficient density to act as a contaminant filter, so that contents within the bag arrangement can be sterilized by a gas sterilization procedure.

Abstract: A flexible bag operable as a coin bank includes first and second sidewall members and a base portion. The sidewall members and base portion may be constructed from a flexible plastic material, such as a polyethylene plastic, which is capable of being heat-sealed. The flexible bag includes the plurality of edges, all of which are sealed to define an internal coin receiving chamber. Access to the chamber is provided by means of a coin slot, enabling coins to readily be placed into the bag, one at a time. Preferably the coin slot is sized to generally inhibit removal of large numbers of coins from the bag, without substantial difficulty. The flexible bag includes retaining means serving to keep the coin slot held substantially open for facilitating deposit of coins therein, at preferred times. The flexible bag bank may be constructed from materials sufficiently inexpensive and easy to cut open to facilitate complete destruction of the bank, when access to the coins is desired.
