摘要:
A method and structure for a non-reopening extruded plastic profile fastener wherein complementary rib and groove type profiles are constructed and arranged to be pressed into interlocking relationship, and provided with restraining means against permanent interlocking so that the fastener can be handled as an assembly with the profiles aligned for interlocking but not interlocked until the means are overridden and the profiles pressed into interlocked relation with one form of the overridable means being a frangible diaphragm across the groove to prevent movement of the rib and in another form a projecting strut which is yieldable with the application of a predetermined force or which is removable to permit the profiles to be moved to fully interlocked position.

Gusseted bags are provided with extruded reclosable plastic profile stirps along free upper end portions of face walls flanking a bag mouth, the fastener strips being free to separate throughout their lengths when opening the bag mouth to the full extent permitted by opposite side expanding gussets of the bag so that free access into the bag such as for inserting or removing contents such as a tray loaded with products such as cookies, or the like, or for pouring contents therefrom selectively between either of the separated ends of the upper end portions of the face walls and the cooresponding ends of the fastener strips is permitted. The fastener strips may have interlockable wraparound extensions. A method of making the bags is disclosed.
摘要:
A bag chain structure and method of making wherein fastener strips are attached across the surface of the film at predetermined intervals with the fastener strips having a plurality of rib and grooves so that the rib and grooves interlock when the strip is folded upon itself and the film is doubled so that the lateral edges are in adjacency and are joined, cross-seals are placed across the doubled film at intervals spaced from the fastener strips to form the bottom of the bag; and tear perforations are placed in the doubled film between the bottom seal and the fastener so that individual bags can be torn off of the continuous film sheet.

Integrally serially connected top fillable bags have closed bottoms and sides and reclosable zippers from which pull flanges extend upwardly. The bags are separated along their sides including the pull flanges and continuous connecting strips connect the tops of the pull flanges and have guide ribs extending continuously therealong for engagement by supporting jaws which serve to open the serially connected bags one at a time at a filling station for filling. After the filling station, the filled bag is separated from the connected bags by removing the connecting strip from the tops of the pull flanges of the filled bags in line with or below the top ends of the separations between bags. The zipper of the filled bag is closed by a closing device such as pinch rolls through which the bag is pulled and the connecting strips removed.
摘要:
A method of and apparatus for packaging a blocky product such as cheese, into a wrapped envelope package, with material especially adapted for said packaging and wherein a bottom face of the product article is engaged on a panel area of the wrapper sheet which sheet has extended portions that are wrapped about the article and sealed across a top face of the article, with one of the portions of the wrapper sheet having a reclosable zipper and a web portion alongside said zipper which is adapted to be severed or ruptured to provide a mouth opening for access to the article within the package and the mouth opening being reclosable by the enclosed zipper. The zipper may be provided with structure to prevent its being pulled open during the wrapping and sealing of the wrapper about the article. The web portion may have guidance for severing or rupturing the same when access is desired into the package.
摘要:
A flexible reopenable slide closure structure having first and second flexible plastic continuous fastener strips each having at least three continuous coactingly shaped interlocking releasable rib and groove elements extending along the strip with a closure slider positioned on the strips and guided to move therealong in a closing direction with the slider having opposing faces for pressing the strips together, one of the faces having a raised ridge extending laterally across the strip and extending at an angle to the direction of the strips so that the strips are pressed together in such a way that the ribs and grooves at one side are interlocked first with the ribs and grooves at the center second and the ribs and grooves at the other side last so that the ribs and grooves do not laterally fight each other while moving to closing relationship.
摘要:
A separably connective flexible toy assembly comprises a plurality of generally flat elongated geometric flexible toy members each of which has at its opposite ends complementary fastener means, at least one of the members having a slit intermediate its length through which another of the members may project whereby to provide a multi-arm configuration, each of the arms being bendable and twistable along its length such that the fastener ribs and grooves of the arm ends are interlockable with fastener ribs and grooves of another arm end of the same member or of another member.The members are particularly adapted to be made up from an extruded section formed from synthetic plastic material and severed to provide the individual members.The assembly may be supplied as a kit having a plurality of separate members adapted to be assembled together by the user.
摘要:
Flexible closure strips to be releasably interlocked wherein each of the closure strips has first and second sets of interlocking profiles with the first set facing in a first lateral direction and the second set facing in the opposite lateral direction and being shaped and sized so that they interlock with each other in either lateral direction.
摘要:
An improved reclosable fastener structure for bags or the like including first and second continuous strips of flexible plastic with outer sides of the strip forming opening flanges and inner sides of the strips forming bag mounting flaps, continuous fastener profiles for each of the strips including a first fastener profile integral with one surface of the first strip and a second fastener profile of a size and shape to releasably interlock with the first profile and being integrally connected with the second strip immediate its edges and a continuous interconnecting film web of substantially uniform width extending between said strips and integrally connected at its outer edges at a location between the profiles and the edges of the mounting flaps of the first and second strips.
