Patent number: 5475969Abstract: An improved system for applying labels to pharmaceutical vials or the like includes a heating tunnel assembly having an insulated heating chamber defined by a first stationary portion and a second removable portion, with a heater positioned within the insulated heating chamber. The assembly includes movable mounting structure for mounting the second removable portion of the insulated heating chamber for movement between a first position engaged with the first stationary portion, and a second retracted position remote from said first portion. An actuator is provided for moving the second portion of the insulated heating chamber into its engaged position, while a biasing spring resiliently biases the second removable portion of the chamber toward the retracted position. As a result, the heating tunnel assembly will automatically be opened to prevent products from overheating or burning in the event of an emergency that disables the actuator.Type: GrantFiled: July 23, 1993Date of Patent: December 19, 1995Assignee: McNeil-PPC, Inc.Inventor: Harry Sowden

Patent number: 5466290Abstract: The present invention is directed to an apparatus for coating a product such as a medicament in the shape of a tablet. The apparatus includes a plurality of plates for receiving and retaining the products and means for advancing the plates on a conveyor to various processing stations. At a dipping station, a dipping means lowers and raises at least one plate into a first coating tank for coating at least a portion of the product. At a rotating station, a rotation means rotates one of the plates containing the product for spreading the coating on the product. After rotation, a first elevator transfers the plates from the conveyor to a dryer disposed above the conveyor.

Patent number: 5453296Abstract: A method of making an absorbent product in which pressure sensitive adhesive is used to attach the product to a user's undergarment. The product does not require release paper to protect the adhesive from unintended contact prior to use. The product is made by forming depressions in a fluid impervious barrier so as to create raised areas in the barrier that protect the adhesive. The depressions may be formed in the garment facing surface of the barrier and the adhesive applied within the depressions so that the raised areas adjacent the depressions protect the adhesive. Alternatively, the depressions may be formed in the surface of the barrier opposite the garment facing surface so as to create raised areas in the garment facing surface and the adhesive applied adjacent the raised areas.Type: GrantFiled: May 4, 1993Date of Patent: September 26, 1995Assignee: McNeil-PPC, Inc.Inventors: Nels J. Lauritzen, John T. Ulman

Patent number: 5453143Abstract: A method for making an absorbent article, such as a sanitary napkin, having tabs. A first series of patches of a hot melt type pressure sensitive adhesive are applied to one side of a double-sided release strip. The release strip is then placed against the central portion of the absorbent article so that the first adhesive patches bond to the central portion. A second series of patches of the adhesive are applied to the other side of the double-sided release strip and tabs are folded over the central portion so that the second adhesive patches bond to the tabs. Since the release strip has been coated with a release agent, such as silicone, on both of its sides, the first and second patches of adhesive bond to the central portion and the tabs, respectively, with greater tenacity than they did to the release strip. When the user removes the release strip prior to use, the first and second adhesive patches remain on the central portion and the tabs.Type: GrantFiled: October 24, 1994Date of Patent: September 26, 1995Assignee: McNeil-PPC, Inc.Inventor: Michael J. Menard

Patent number: 5453085Abstract: The invention is related to a tampon applicator (10) made of plastic, especially for feminine hygiene, consisting of an approximately cylindrical outer sleeve (12) which is intended for receiving a tampon (14) and in the rear end of which there is inserted in an axially non-displaceable manner hollow grip piece (16), in which a slide (18) is arranged so as to be axially movable. The outer face of the slide (18) is connected in the vicinity of its fromt end, to the inner wall of the grip piece (16) by means of at least one predetermined breaking point (24). Thus, the tampon applicator can be produced from just two injection-molded parts allowing reduced expenditure on machinery and assembly. The slide is held captively in the grip piece until the tampon applicator is put to use.Type: GrantFiled: October 14, 1993Date of Patent: September 26, 1995Assignee: McNeil-PPC, Inc.Inventor: Hans-Werner Schoelling

Patent number: 5447677Abstract: An apparatus and method for making absorbent products in which a first material, such as absorbent fluff formed from wood pulp, is introduced into a vacuum forming chamber. A portion of the fluff is deposited into the cavity of a mold transported through the forming chamber by a forming wheel so as to form a layer of pure fluff within the bottom of the mold cavity. A second material, such as superabsorbent particles or heat stabilized fibers, is introduced into the forming chamber so that streams of the first and second materials collide within a mixing zone. As the mold continues it travel through the forming chamber, a mixture of first and second materials from the mixing zone is deposited within the mold cavity, thereby filling it. The portion of the mixture that extends above the surface of the mold is scraped off by a scarfing brush that directs the mixture back into the mixing zone, thereby creating turbulence that ensures thorough mixing of the two materials.Type: GrantFiled: June 2, 1993Date of Patent: September 5, 1995Assignee: McNeil-PPC, Inc.Inventors: Thomas Griffoul, Martin Wislinski
