    摘要： Apparatus for sealing the mouth of a plastic bag while forming a handle therein. The apparatus includes a housing having a mouth into which the bag is inserted. Reciprocating heating means are provided for producing a pair of heat seals in the portion of the bag inserted within the housing mouth to seal that portion of the bag and to form a pocket therebetween. The heating means is brought into contact with the bag to effectuate the sealing by motor means and includes a pair of elongated electrical heating elements for producing heat when energized. The elements are disposed at an angle to one another but their heating faces are coplanar. Control means are provided for reciprocating the heating means and for energizing the heating elements in response to the insertion of the bag in the housing mouth and for deenergizing the heating elements a preselected time thereafter. The control means also cause the heating means to move out of contact with the bag after a predetermined period of time. The control means precludes the heating means from repeating the sealing operation on any one bag should the bag be left within the mouth of the housing.

    摘要： A plastic bag comprising a front wall, a rear wall and a sealed bottom. A purchased commodity is placed in the bag and the open top of the bag is folded over, with the folded portion being positioned against the rear wall of the bag. A pair of convergent heat seals secures the folded portion to the remainder of the bag, thereby forming a pocket to receive a hand. The bag is then carried by placing a hand in the pocket.

    摘要： An apparatus for forming a handle on a plastic bag while at the same time sealing the mouth of the plastic bag. The apparatus includes a housing having an opening into which the bag is inserted. A reciprocating heating means is provided for producing a pair of laterally extending, spaced parallel heat seals. Second heating means is provided for cutting an opening between the spaced parallel heat seals. The cutting heating means also seals the plies of the plastic bag at the point where cutting takes place.The apparatus and method of this invention also form a novel plastic bag, which comprises a front wall, a rear wall and a sealed bottom. A purchased commodity is placed in the bag and the opened top of the bag is closed by the spaced laterally extending parallel heat seals. An opening is formed between the spaced parallel heat seals, and a hand can be inserted in this opening for carrying the bag. The edge of the opening comprises a continuous heat sealed bead formed from the front and rear walls.
