Patent number: 5890350Abstract: An automatic packaging machine inserts small items, such as candy coated chewing gum, into a box with the small items arranged in a desired orientation. First, the small items are swept into a grid of individual pockets in plates on a conveyor. Then, the grid is inverted over an insertion tray having grooves which receive the small items without disturbing the desired orientation. The entire tray is inserted into a box and then withdrawn from the box. A ridge is formed adjacent said grooves for lifting a side of the box confronting the small items while the tray is inserted into the box so that there is almost no friction between the small item and the box, which might otherwise disturb the desired orientation. The small items are blocked during a withdrawal of the tray so that they are laid down in the desired orientation on the bottom of the box.Type: GrantFiled: April 28, 1997Date of Patent: April 6, 1999Assignee: Tisma Machinery CorporationInventor: Steven Tisma

Patent number: 5010929Abstract: The invention greatly increases the versatility and the speed at which an automatic packaging machine may fill boxes or other containers. Two fill stations are provided for alternately filling empty boxes as they move in single file past two separate fill stations. If no empty box is available to receive the product, a transfer cup is diverted and travels over one of two alternate paths at the fill station would otherwise fill the missing box. The product dumped from any non-diverted transfer cup goes into a corresponding box. The product dumped from any diverted transfer cup is returned to the start of the fill cycle. This way, the machine may simultaneously (i) fill one box with two separate products, (ii) fill alternate boxes with two different products or product volumes, or (iii) fill different kinds of boxes with product. A swing arm enables a part to be moved at each of the fill stations so that it may be repaired, maintained or cleaned without having to disassemble the machine.Type: GrantFiled: May 9, 1989Date of Patent: April 30, 1991Assignee: Tisma Machine CorporationInventor: Steven Tisma

Patent number: 4856566Abstract: The invention greatly increases the speed at which a fill step may be completed in an automatic packaging machine. Instead of the usual process where a gate opens and closes for dumping product into each empty box, a plurality of bottomless measuring cups and transfer cups are moved in an aligned sequence with the corresponding boxes. These cups move over planar surfaces which function as the bottoms of the cups and keep the product in place within the cups. At selected locations, the cups pass over interruptions in the surfaces so that the product may fall out of the cup and into an underlying structure.Type: GrantFiled: March 4, 1988Date of Patent: August 15, 1989Assignee: Tisma Machine CorporationInventor: Steven Tisma

Patent number: 4713928Abstract: An automatic packaging machine includes a loading station for simultaneously and sequentially picking up a plurality of elongated products and deposing them in a spaced parallel alignment within a box. At the time of loading each of the products has an initial volume which is substantially greater than the volume which the same product will have after it has settled over time within the box. Thus, the box id overfilled by an amount which will make it full after the products have settled. Then, the overfilled box is advanced to a closing station, where the lid is closed over the filled box without damage to the products. This immediately reduces the volume of the products to the volume which they would have after they have settled.Type: GrantFiled: September 9, 1986Date of Patent: December 22, 1987Assignee: Tisma Machine CorporationInventor: Steven Tisma

Patent number: 4548593Abstract: The invention provides a process for making a dry powder box with greater geometrical stability and free of pin holes, gaps and the like through which powder may sift. The process uses a carton blank having a bottom closure wherein a pair of relatively large, opposing dust flaps are first folded into the carton tube, in order to define, maintain and stabilize the cross section of the carton. Then, a pair of relatively smaller, opposing major flaps are folded and glued over the open sides of the large dust flaps. This combination of flaps keeps the large flaps from working out of alignment and helps maintain the cross sectional stability of the box. The top of the carton may be a gable having panels at the ends of the gables which are slightly larger than the cross section, of the gable roof sides. When the gable is formed, the larger ends are pushed down to create a leverage which closes the top opening more securely. The cut lines which form and define the flaps extend across approximately 80.degree.Type: GrantFiled: August 1, 1984Date of Patent: October 22, 1985Assignee: Tisma Machine CorporationInventor: Steven Tisma
