Patent number: 6058681Abstract: A method is provided for bagging produce in sealed bags in an automated manner. The method comprises the following steps. A pair of thermoplastic sheets are advanced along a process line with the sheets being in parallel, abutting relation. A longitudinal seal line is formed between the sheets near to but spaced from the lower edges thereof to define a bag header. Transverse slits are formed in both of the sheets together, with the edges of the slits being heat sealed, as with a hot knife, to form separate bags between the slits. The slits extend across the lower edges of the sheets, but are spaced from the upper edges. Thus, the sheets remain integral despite the formation of multiple bags therein. Produce is dropped between the thermoplastic sheet upper edges into the bag. The bags then may be horizontally slit to substantially intersect the transverse slits and to separate a horizontal strip of the sheets including the upper edges, while bottom-supporting the bags.Type: GrantFiled: February 21, 1997Date of Patent: May 9, 2000Assignee: Tagit Enterprises CorporationInventor: Michael J.

Patent number: 5937617Abstract: A pouch for holding liquids includes a pre-inserted straw within the pouch. A top end of the straw is exposed by removing a portion of the pouch. For manufacture, a web of flexible packaging material, suitable for forming a pouch or bag for storing liquids, is advanced forward in a pouch forming direction. A single straw of suitable length to fit within the confines of a resulting pouch is cut from a continuous length of straw material. The single straw is placed onto the web of packaging material in a location that will be on the inside surface of a single wall of the pouch and there it is secured in place preferably by a heat seal between one side of the straw and the inside surface of the pouch wall. The resulting pouch web material, having a plurality of straws positioned along its length provides a feedstock for forming pouches with pre-inserted straws when using a so called form and fill method of forming pouches or when making pre-made pouches.Type: GrantFiled: May 1, 1998Date of Patent: August 17, 1999Assignee: Innoflex IncorporatedInventor: James W.

Patent number: 5927052Abstract: A method for flavoring tea with a granular flavoring agent includes the step of removing from a reservoir a predetermined amount of granular flavoring agent. The predetermined amount of granular flavoring agent is placed as a small heap onto a moving endless filter paper strip. Subsequently, a predetermined amount of tea is placed adjacent to or onto the small heap of flavoring agent. The tea and flavoring agent heaped onto the filter paper strip are subsequently enclosed in a tea bag made from the filter paper strip accordingly. The inventive device for performing the method includes a device for moving the endless filter paper strip in an advancing direction. A tea metering device and a metering device for a flavoring agent are positioned directly above the endless filter paper strip whereby the metering device for the flavoring agent is positioned upstream of the tea metering device in the advancing direction.Type: GrantFiled: September 27, 1996Date of Patent: July 27, 1999Assignee: Teepak Spezialmaschinen GmbHInventors: Helmut Nippes, Michael Klein

Patent number: 5878549Abstract: An easy open tear control package, preferably a pouch, from a film of polymeric barrier material is disclosed. Methods and films for making of such packages are also disclosed. The easy open tear control feature arises from roughening portions of the outer or inner surface of the films, prior to fabricating into the package. The roughened portion is on one face or on each face of the package and is at least a full width of a seal when the film is made into the package. The roughened portion can extend the entire width of the package and can be of any desired length.Type: GrantFiled: September 29, 1997Date of Patent: March 9, 1999Assignee: American National Can CompanyInventors: Richard Littmann, Ulrich Weingartner, Thomas S.

Patent number: 5829230Abstract: Method for bagging plurality of compressible absorbent articles which are arranged in parallel, one beside the other. The bag has an approximately rectangular base, a front side, a rear side, two narrow sides, and an upper side and is closed on all sides. The bag also has a line of weakness which marks an opening for the individual removal of the articles. The height of the bag is greater than the depth of the bag, the line of weakness extends, midway along the bag, from the longitudinal center of the upper side, toward the base, about half way down the front side of the bag. The base has a downwardly directed supporting band. The absorbent articles do not exerting sufficient pressure on any of the sides of the bag filled with said articles to cause the opening to gape open. The opening can be formed by bending the bag to open the line of weakness, and it closes after removal of the product when the bag is replaced on its supporting edge.Type: GrantFiled: September 22, 1997Date of Patent: November 3, 1998Assignee: McNeil-PPC, Inc.Inventor: Wolfgang Hartz
