Abstract: A method for the multi-track tailoring of transdermal therapeutic patches having at least a one-layer, adhesive reservoir foil containing an active ingredient, which is disposed between an adhesive back foil and a removable protective foil. The reservoir foils are applied per track with their adhesive layers on a transport element moving discontinuously in the longitudinal direction of the reservoir foils. After separating sections of the size of a patch or band aid the same are transferred to a further transport element that is moved continuously for depositing the same thereon in spaced relationship. The present invention provides a method for multi-track tailoring, wherein web-shaped reservoir foils, which can be unwound from rolls, may be utilized without producing any waste containing the active ingredient.

Abstract: A method is disclosed of making a component consisting of a substantially cylindrical support through which there is a substantially coaxial orifice and a membrane welded to one end of the cylinder substantially perpendicularly to a longitudinal axis of the support. A substantially plane membrane is welded to one end of a support substantially perpendicularly to a longitudinal axis of the support and, after cooling, the support is torn off the membrane in a direction substantially perpendicular to the plane of the membrane so that a portion of the membrane substantially corresponding to the end of the cylinder remains welded to the support. The method can be applied to making two-part stoppers for straws, in which case the membrane is microporous, hydrophobic, impervious to liquids and permeable to gases and the support is an insert made from a material chosen from an elastomer material, a thermoplastics material and a thermoplastics elastomer material.

The tab is easily lifted and grasped by the fingers to pull the seal off the mouth.

Abstract: A method of making an elongate strip for the production of a sealing member includes, as a first step, applying a plurality of strips of a first adhesive to one of a membrane and a first sheet, the membrane and the first sheet are then bonded together so that composite portions are formed where they are bonded together by the strips of the first adhesive, and separated portions are formed where the membrane and the first sheet are free from one another. The other side of the membrane is then coated with an additional layer of adhesive, for example a hot melt bonding material. Then, sealing members can be cut from the resultant composite elongate strip, with each sealing member having a composite portion in which the membrane and the first sheet are bonded together and a separated portion in which the membrane and the first sheet are free of one another. The free portion of the first sheet then forms a tab, for removal of the sealing member, in use, after it has been bonded to the lip of a container.

Abstract: An overlapping layer (24) of a first body of deformable material is pressed by an edge (78) of each of a plurality of blade members (42) into an overlapped layer (26) of a second body of resilient material forming slots (74) in the second body with ribs (88) of the first body displaced therein. The blade members (42) are removed while the ribs (88) are retained in the slots (74) and gripped by the surrounding resilient material. The blade members (42) may be adjustably clamped in a cartridge (40) which is removable from the splicing apparatus (10) for adjustment and replacement of the blade members (42) so that they conform to the surface profile (82) and splice interface line (80) of the bodies to be spliced.

Abstract: A method of manufacturing a container cap with a concealed mark is disclosed. The mark is provided to the central portion of one of both the inside face of the top panel and one side of a seat member made of a thermoplastic material. The seat member is then placed on the inside face of the top panel so that the one side of the seat member faces the inside face of the top panel. The seat member is thereafter heated for softening. The other side of the seat member, heated and placed on the inside face of the top panel, is depressed to form a manually tearable line surrounding the mark in the other side of the seat member, thus defining a gasket portion in the seat member outside the tearable line and a manually removable portion, overlying the mark, inside the tearable line, and to attach a gasket portion to the top panel.

Abstract: A cap-lining machine is constructed with a minimal number of mechanical parts and is provided with a modular and quickly replaceable liner punch and insert station, which readily may be changed to accommodate caps of different diameters with a minimum amount of down time. In addition, sensing switches are employed with an electronic control system in lieu of conventional mechanical connections to prevent the machine from moving on to the next step in its operation unless all previous steps of operation have been completed in proper sequence. Operation interruption is accomplished in a jam-proof manner.

Abstract: The present invention discloses a sheet material useful as an innerseal that comprises a dimensionally stable substrate having at least 0.001 g/cm.sup.2 of a tack-free, shear-activated adhesive on one surface. The composition includes from 1 to 15 parts by weight of a block copolymer, from 1 to 25 parts by weight of a tackifier, and from 60 to 100 parts by weight of either a microcrystalline wax or an amorphous polyolefin. A mixture of the two can be used.The sheet material is shear-activated and does not adhere or block to itself or other surfaces until a shear force is applied to it. Additionally, it does not require special heating equipment in order to adhere it to surfaces. In a preferred aspect of the invention the innerseal leaves a residue on the lip around a container opening thereby providing a visible indication of removal.

Abstract: A device and method for applying a semi-liquid adhesive material in a preselected pattern upon a surface such as the inner surface of a container cap such that a liner may be adhesively connected thereto. The device and its manner of operation are particularly suited for the application of hot melt adhesive to container caps of the type having a central recess surrounded by an annular ledge. A member having a longitudinal bore in which a shaft having one or more external helical grooves is rotationally disposed, cooperates to form the applicating device. One end of the member is operationally associated with a supply of semi-liquid adhesive such that rotation of the shaft with respect to the member will force adhesive along the separate helical paths and on to the receiving surface of the cap in the desired configuration.
