摘要:
A flexible film package having an adhesive based reclosable fastener having a flexible film substrate forming a plurality of package walls sealed to form an interior cavity for receiving a product; the plurality of walls having at least two opposing flexible walls; a package mouth, initially sealed, to permit access to the interior cavity; a low tack pressure sensitive adhesive (LTPSA) layer disposed on each of an exterior surface of the parallel walls, the LTPSA sized and oriented in positions to oppose one another at a plurality of positions when the package is reclosed to allow progressively decreased size of the interior cavity as product is removed; and wherein a bond strength of the LTPSA to the flexible film substrate is greater than an adhesion between LTPSA areas. The mouth can be formed by a peelable seal or by a defined area of weakness.

The support device includes a support and a pair of bars spaced apart from each other. The bars include a slot configured to enclose peripheral side edges of a flexible pouch. In one embodiment, the bars are wing shaped and include a first member and a second member. The first member is angled with respect to the second member. The slot extends inwardly from an inner surface of the bar and is disposed between the first and second member. The slot is configured to receive a peripheral side seal of the flexible pouch. The first and second members help keep the body of the pouch within the grips of the gripper. In a second preferred embodiment, the bars are an elongated member. The slot is disposed along the inner surface of the bars. The bars have a length sufficient to receive the side peripheral seal of the pouch.

A vacuum sealing machine includes a base assembly having an upper base portion removably secured to a lower base portion and displacing relative to the lower base portion from a closed position to an open position. Two or more heating strips are disposed on the lower base portion, and each of the heating strips is adapted to seal a portion of an open end of a sealable bag disposed between the lower and upper base portions. At least one securement feature is disposed on the upper base portion and is adapted to apply pressure to a portion of the open end of the inserted sealable bag when the sealable bag is sealed by at least one of the heating strips. In addition, A control unit including at least one microprocessor and a memory unit is in communication with each of the two or more heating strips.

A cutter includes a male blade, a female blade, an advancement and retraction controller and a suction device. The male blade includes: a linear cutting portion linearly shaped with a predetermined thickness in a center part; a rounded cutting portion where a radius having a substantially arc shape in planar view is continuously formed from the linear cutting portion; and an end provided adjacent to the rounded cutting portion. The female blade has a fitting portion that is a hole conforming to the profile of the male blade in planar view and to which the male blade is fitted. On a lateral side of the female blade, an elongated hole for inserting a base film from one lateral side to the other lateral side is formed as an insertion portion.

An adjustable pouch machine comprises a vertical sealer module forms transverse seals between two plies of a pouch web to partially define a plurality of pouches. Rollers selectively tension and relax the web on the vertically oriented wheel, allowing them to drop away from heated lands on emergency and cycle stops. A filler wheel has a plurality of adjustable gripper units mounted directly thereon for transporting independent separate pouches cut from the pouch web. An adjustable knife is selectively provided with changeable knife hub sets to handle a variety of pouch sizes where a filler wheel alternately first fills and seals pouches in a train. Gear linkage accommodates variation in distance between hubs of different sets. Various embodiments, apparatus and methods are described.
