Flexible Bags POSTED ON:
This invention relates to hang-up containers and is more particularly concerned with hang-up bags or sacksprovided with separable fasteners and carrying and hang-up hook/handles.Heretofore, there has been provided a method for the production of a closeable hang-up container consisting of a bag or sack provided with a hook and releasable pressure- slide- or push-closing fastener extruded in a pair of strips, according towhich a tube or a double flat film made of thermoplastic synthetic material is endlessly extruded and subsequently is conveyed together with the fastener strips into an automatic machine where the fastener strips are connected with the flat walls of thetube or the double flat film by means of welding and the tube or the flat film and fastener assembly is divided by means of tear seals into individual bags or sacks. The resulting container has one closure strip in one piece on one side provided with aconnecting strip extending downwardly in the plane of the bag or sack wall from a connecting line with the closure strip and is provided with a reinforced band area extending from the connection line upwardly. A carrier hook is stamped out of thereinforced band area.According to the present invention a principal object is to produce containers of this type entirely automatically, but without waste of material and to provide such containers with carrying handle and hook means that may be used for all sizes ofbags.In solving the problem according to the present invention, a method is provided for producing a sealable hang-up container which may be in the form of a bag or sack with a carrying handle and hang-up hook and a releasable pressure- slide- orpush-closure extruded in two strips and wherein a tube or double flat film of thermoplastic synthetic material is endlessly extruded and subsequently conveyed together with the closure strips to an automatic machine from which the closure strips with theflat walls of the film strips or tube or of the flat film

A hang-up container made from thermoplastic syn&#194;&#172;&#226;&#168;thetic material has a bag or sack body attached to a&#226;&#168;separable fastener comprising extruded pressure- slide-&#226;&#168;or push-fastener strips one of which has an upwardly&#226;&#168;extending reinforced carrying portion which may be&#226;&#168;provided with a reinforcing bead therealong at juncture&#226;&#168;with its closure portion and which has attached thereto&#226;&#168;an upwardly extending hook/handle. Bag type contain&#194;&#172;&#226;&#168;ers as thus described are especially adapted to be pro&#194;&#172;&#226;&#168;duced in an automatic production machine wherein&#226;&#168;body film material and the fastener strips are brought&#226;&#168;together and integrally welded, the prefabricated&#226;&#168;hook/handles are welded onto the carrying portions,&#226;&#168;the bags are successively separated along tear seals,&#226;&#168;and the separated bags carried away from the machine.
The hook/handle part may be provided with a handhole&#226;&#168;and an upwardly projecting hanger hook, or with a&#226;&#168;handhole into which a hanger bar entry slot extends at&#226;&#168;one side with a central hanger bar recess notch opening&#226;&#168;downwardly in the handle into the handhole.

In the modification of FIG. 3, a hook/handle part 16&#226;&#168;is shown which is also adapted to be made as an ex&#194;&#172;&#226;&#168;truded or injection molded part, but which is substan-
provided with an upper diagonally laterally extending tic film bag sidewall panels, each fastener strip having&#226;&#168;entry slot 17 in the handle portion above the handhole separable fastener means to engage closingly with the&#226;&#168;and leading to the entry end of a hook notch 18 which other, one of the fastener strips including an attach-&#226;&#168;opens into the handhole and is adapted to receive a ment web secured to one of the bag wall panels and&#226;&#168;hang-up rod received through the slot 17 and then into 5 having a carrying web area extending in the opposite&#226;&#168;the notch 18. Similarly as in FIG. 2, the lower margin of direction from juncture of the attachment web and&#226;&#168;the member 16 is provided with a weld-on area 14.
As shown in FIG. 4, the separable fastener or closure,&#226;&#168;generally identified at 19, comprises at one side a de&#194;&#172;&#226;&#168;pending fastener strip 20 which is connected to one 10&#226;&#168;sidewall of a thermoplastic film bag body 21 by way of&#226;&#168;a connecting line or juncture 22 along the upper edge&#226;&#168;of the strip 20 from which extends an integral depend&#194;&#172;&#226;&#168;ing connecting or attachment flange or web 23 and&#226;&#168;which is welded to the bag body panel extending gener- 15&#226;&#168;ally downwardly in a plane therefrom. Extending up&#194;&#172;&#226;&#168;wardly from the juncture 22 is an integral carrying&#226;&#168;band flange or web area 24 which extends the full&#226;&#168;length of the fastener, and thus the width of the bag,&#226;&#168;and is reinforced throughout by being of substantially 20&#226;&#168;greater thickness than the strip 20 or the coextensive&#226;&#168;attachment flange 23.
For heavy duty purposes, the carrying flange web&#226;&#168;area 24 is provided with an integral reinforcing bead rib&#226;&#168;25 extending immediately above and along the juncture&#226;&#168;22. This provides a desirable stiffness for the carrying&#226;&#168;web.
At the opposite side of the bag, a fastener strip 26&#226;&#168;complementary to the fastener strip 20 is provided with&#226;&#168;the customary attachment flange or web portion which&#226;&#168;is welded to the associated side panel of the bag body
In the completed bag, the selected form of hook/han&#194;&#172;&#226;&#168;dle is permanently affixed centrally to the upstanding&#226;&#168;carrying flange web area 24 by weldng the attachment&#226;&#168;margin or weld area 14 thereto, as best seen in FIGS. 5&#226;&#168;and 6. By having the hook/handle part of as narrow a&#226;&#168;width as practicable, and prefabricated as an injection&#226;&#168;molded or extruded part, the hook/handle part is&#226;&#168;adapted to be applied to bags which are as narrow as&#226;&#168;the hook/handle part itself, or of any preferred greater&#226;&#168;width. The horizontal reinforcing bead rib 25 assists in&#226;&#168;maintaining the bags of greater widths than the hook/&#194;&#172;&#226;&#168;handle portion against sagging at the sides.
