| 26 | Metered flexible dispensing package | US651110 | 1996-05-21 | US5746352A | 1998-05-05 | Arthur P. Corella |
| A first embodiment of a package including superimposed flexible opaque and transparent sides and a circumferential peripheral seal determining an interior sealed enclosure for storing a liquid material includes two contiguous depending seals separated by a preformed slot dividing the enclosure bilaterally into a storage reservoir and a dispensing channel in fluid communication. The dispensing channel includes a closed lower end contiguous to a notch in the peripheral seal. Tearing the package at the notch results in collaterally tearing open the channel lower end and a contiguous portion of the peripheral seal, thereby enabling removal of package contents. Use of a ruled scale imprinted on the opaque side proximate to the dispensing channel and viewing through the transparent side the disposition of material in the channel enable the selection of a measured quantity of material to be expelled from the channel. A second embodiment is identical to the first embodiment except that a continuous divider which is easily torn to define a slot replaces the vertical slot separating the reservoir and channel. A third embodiment is identical to the second embodiment except that a scored line adjacent to the channel lower end enables a flap, formed when the package is torn open, to be folded upwardly where it can be secured to the package, thereby sealing the channel to prevent material leakage. | ||||||
| 27 | Multi-compartment package, system and method | US699036 | 1996-08-19 | US5724789A | 1998-03-10 | Arthur P. Corella |
| A peripherally sealed, juxtaposed, multi-compartment, flexible package is provided which includes a pair of outer walls and at least one separator wall disposed between the outer walls for dividing the package into a plurality of compartments. All of the walls are sealed at a common peripheral terminus, and flowable material is disposed within each of the compartments. The package is adapted to be torn open to simultaneously dispense and admix the flowable material. The multi-compartment dispensing package is manufactured by feeding at least three sheetings of heat sealable flexible film through a first embodiment of form-and-fill packaging instrumentation. A two-compartment dispensing package is manufactured by feeding two sheetings of film through a second instrumentation embodiment including an assembly dividing one sheet into two halves which become outer walls. | ||||||
| 28 | Thermoplastic bag structure | US624817 | 1996-03-26 | US5709641A | 1998-01-20 | Edward A. Vaquero |
| A thermoplastic bag structure and method for making and packaging thermoplastic bags such that their tops are easily identified and the bags are easily opened. The method for producing these bags begins with cutting a flattened thermoplastic tube into two portions. At least one of the two portions is then collapsed to form a sheet of material having a pair of thermoplastic layers, a straight folded bottom edge and a pair of top edges, at least one of which has a skewed-cut. Bag side structures are formed in the sheet of material at about bag-width distances apart. The bags are then folded a predetermined number of times, in a direction transverse to the bag side structures, so that the skewed-cut top edge(s) of each of the bags remains exposed. | ||||||

The retractable separators (68) are mounted on a conveyor (83) and each separator (68) in turn temporarily separates the webs (51,53), for insertion of a port (45), fitting or the like, whereupon the separator (68) may be retracted and the port (45) may be sealed into the packages (41) being manufactured. The preferred separator (68) has a shaped head (170) on the end of a reciprocating shaft (158). The head (170) may be enlarged and may have a tapered end (171) for insertion between the webs (51,53). | ||||||
| 30 | Method and apparatus for continuously forming bags | US959655 | 1992-10-13 | US5662575A | 1997-09-02 | Hisatoshi Saito; Masamitsu Yano; Satoshi Takane |

| 34 | Method and apparatus for registration of a seal on a plastic bag | US289426 | 1994-08-12 | US5587032A | 1996-12-24 | Stephen A. Saindon; Peter J. Gietman, Jr.; Nicholas J. Nagel |
| A plastic bag making machine includes a cylindrical drum with a variable diameter. A plurality of seal bars define the circumference of the drum, and are substantially parallel to the drum's rotational axis. The bags are made from a plastic film with registration marks that are detected by a detector disposed near the film. A detector also detects each revolution of the drum and an encoder provides signals indicative of the position of the film. A controller determines the distance phase of the registration marks and the rum size error. The drum diameter is adjusted in response to an output of the controller in such a way as to correct for both the initial drum size error, the initial phase error, and the phase error accumulated while the drum diameter is being corrected. | ||||||
| 35 | Apparatus and method for fabricating breather bags | US468961 | 1995-06-06 | US5571361A | 1996-11-05 | John F. Stuerzel |
| An automated continuous heat sealing apparatus and method are disclosed having dedicated operating stations for fabricating continuous hermetically sealed tubular structures and individual bags from rolls of continuous webs of polymer material, the first web including TYVEK.RTM., as breather bags adapted for gas and steam sterilization. The breather bags are customized to any length depending on the settings of the apparatus. A feeding station holding the rolls of continuous webs longitudinally feeds the continuous webs to a first operating station having a slitter for providing a continuous longitudinal strip of apertures in the second continuous web for cutting material from the slitted second continuous web, and for continuously heat sealing a first set of seams to join the first and second webs. A second operating station continuously heat seals a second set of seams to join the second and third continuous webs for forming a continuous tubular structure. An optional third station intermittently heat seals transverse seams at predetermined lengths along the longitudinal length of the continuous tubular structure, and an optional fourth operating station cuts the continuous tubular structure a predetermined distance from the transverse seams to form individual breather bags. | ||||||

| 40 | Method for making bags of synthetic material | US760462 | 1991-09-17 | US5282778A | 1994-02-01 | Fritz Achelpohl |
| A method for making bags of synthetic material in which a tubular foil web of synthetic material is advanced in steps corresponding to the length of one bag. A continuously heated pair (11) of welding jaws grips the tubular foil web (3) of synthetic material prior to cutting and fixes the web in position. The tubular foil web (3) is then cut by means of the transverse cutting knife (10) before the heat of the pair (11) of welding jaws is completely transferred to the tubular foil web (3) of synthetic material. Then the heat is completely transferred to weld the bottom seam of the bag. | ||||||
