Definitions

  • No.: 141,312 7 Device for opening a sealed container comprisingz'a knife; means for raising and lowering the knife off the 1 Foreign Application prlol'lty Dala container; rotating means for rotating the knife around the container portion to be cut out; a fixedly June 5, 1970 Switzerland ..843l/70 positioned j g Shaped in the Shape of the portion of the v container to be cut out; biasing; means holding the [52] US. Cl ..30/6.4, 30/11 knife against the jig guide surface to guide the cutting [5 1] Int. Cl. ..B67b 7/30 to the desired shape v [58] Field of Search ..30/6.4, 11,17, 310
  • the object of the present invention is to provide a device for the opening of foilsealed containers.
  • the device of the invention includes a knife support capable of being lowered on to the container, means for moving the knife support into its cutting position for cutting the foil along the container rim, a suction device which both holds the foil as it is being cut and, when the knife support is lifted after cutting, raises the foil detached from the container.
  • FIG. 1 shows a side view partly in longitudinal section, of a device for opening foil-sealed containers of non-round shape
  • FIG. 2 shows a top view of the said device, partly in section, along line II-II in FIG. 1;
  • FIG. 3 shows another embodiment of a device for opening foil-sealed containers, in side view analogous to FIG. 1.
  • FIGS. 1 and 2 show a device with a baseplate 1 and a lateral support 3 for receiving a rod 5. This is provided at its upper end with a knob 6 which concurrently serves as an abutment for a spring 7.
  • a knife support 9 Rotatably seated on the rod is a knife support 9, inside which is a jig ll rigidly joined to the rod 5.
  • the edge of jig 11 provides a guide surface oriented to face in a direction transverse to the container surface to be opened.
  • the knife support 9 presents two knife holdersl3 and 15. These present guide grooves 17 in which there are two rolls 19. These rolls support the knife holders 13 and 15 on the edge of the jig ll.
  • Fitted to the knife holders 13 and 15 by bolts 23 are knife blades presenting I knife-edges 21.
  • the knife holders 13 and 15 are connected to slides 25 and 29.
  • the slides slide on guide bars 31 and 33, while the middle section 27 remains fixed.
  • Guide bars 31 and 33 extend generally parallel to the container surface to be opened.
  • the slides are connected to the middle section 27 by tension springs 35, 36, 37 and 38 and holder 40.
  • a collar 43 rigidly joined to the knife support 9 holds a lever 45 with a grip 47.
  • the baseplate 1 presents a recess 49 for receiving a container 51.
  • a suction cup 53 Fitted to the lower end of the rod 5 and rigidly joined thereto is a suction cup 53 which, consisting of soft rubber, sits fast when pressed on to a surface.
  • the device operates as follows:
  • the grip 47 is gripped and swung in a plane parallel to the lid foil 52, so that the knife-edges 21 cut through the foil along the container rim 55.
  • a swing through slightly more than 180, such as 185 is sufficient to part the foil 52 reliably from the container 51 while preventing any further portions from being cut by the knifeedges 21.
  • the grip 47 can be moved back slightly, as through a few degrees, and then the knob 6 can be released.
  • the entire cutting assembly comprising the knife support 9 and the suction cup 53 with the detached lid returns upwards to its initial position under the action of the spring 7.
  • the opened container 51 can be easily removed from the recess 49, as sideways, for instance.
  • the jig 11 is formed according to the contour of the container rim 55, which may be rectangular with rounded corners, oval, etc.
  • the slides 25 and29 are slidably arranged on the guide bars 31, 33. They are subject to the action of the springs 35-38, ensuring that the knife holders 13 and 15 rest against the edge of the jig 11.
  • the knife holders 13 and 15 are provided with suitable rolls 19 which substitute a largely rolling friction for a sliding friction between jig edge and holders 13 and 15. Balls may be used instead of rolls.
  • FIG. 3 shows a device analogous to that in FIGS. 1 and 2 for opening foil-sealed containers.
  • a base-plate 60 presents a die 61.
  • a support 63 holds an operating lever64 with a grip 66 and a slot 67 by which the lever 64 is action-connected to a guide pin 68 of a rod 70.
  • the lever 64 pivots on a pin 69 of the support 63.
  • a piston, shaped component 71 with a dog 73 guided in the guide groove 77 of a sleeve 75 is a piston, shaped component 71 with a dog 73 guided in the guide groove 77 of a sleeve 75.
  • the groove of the sleeve fitted in the support 63 is formed in such a manner that its upper portion extends parallel to the axis of the rod 70 or thepiston 71., while its lower portion is bent in the manner shown, so that the dog 73 and, with it, the piston 71, which is free to rotate on the rod 70, first performs an axial movement and thereafter, following the bend of the groove 77, a combined axial and rotary movement.
  • a carrier 78 with carrier bars 80 serve to carry along the bolts 82 in the knife holders 84, which carry knife blades 86 with knifeedges 87. The blades are held by bolts 88.
  • the knife holders 84 are interconnected by springs 89 and the carrier 78.
  • the knife holders 84 rest against a jig 91, and the grooves of the knife holders 84 have rolls 92 or balls intended to guide the knife holders 84 smoothly along the circumference of the jig 91,
  • a suction cup 94 is provided as a terminating element.
  • knife-edges 87 meet the foil 99 and pierce it, whereupon, with the lever 64 continuing its downward movement, the piston 71 performs a rotary movement corresponding to the form of the groove 77, so that the knife-edges 87 move parallel to, or along, the container rim 98 and part the foil 99 from the rim. According to the number of knife-edges 87, the rotary movement performed by the piston 71 is limited to about 95 or about 185.
  • the suction cup 94 which is pressed against the foil 99 and which may be connected to a vacuum device, not shwon, for instance, entrains the detached foil 99, when the lever 64 is lifted, so that, with the lever 64 back in its initial position, the opened container 96 is cleared and can be removed from the die 61. Removal may be effected sideways through a lateral cut-out 95 of the die 61, for instance.
  • the knife support after the cutting of the foil 99 has been completed, is first lifted and then swung back into its initial position.
  • the devices described are designed to open containers of any shape which are closed with foil such as plastic-backed aluminum foil or the like, in cold condition as well as in hot condition, in such a manner that the detached foil lid is raised by the device while the container rim remains undamaged. This is an absolute necessity in view of the container stability required.
  • the die for the container and the jig for the guidance of the knife holders are preferably made as interchangeable parts.
  • the die may consist of plastic or similar material moulded to the shape of the particular type of container.
  • the suction cup serves not only to lift the detached foil lid, but also to keep the lid in position during the opening movement and thus ensure a reliable and neat opening cut.
  • Device for opening of sealed containers comprising:
  • knife moving means connected with said knife means for moving said knife means into cutting engagement with a container and for raising said knife means off the container, for enabling cutting open of the container;
  • rotating means connected with said knife means for rotating said knife means around the container after said knife means has been moved into engagement with said container;
  • holding means for holding a container to be opened fixedly positioned with respect to said knife means
  • jig a fixedly positioned jig, nonmovably connected with said holding means; said jig including a guide surface facing in a direction transverse to the surface to be opened of the container;
