Definitions

  • the invention relates to a package for flowable fillings with a tube, at the ends of which the bottom and lid are attached, of which the lid is made of thermoplastic material without a carrier material, is injection-molded onto the tube along the upper edge thereof and has a pouring device with a closure cap, the Sealing flap on the side opposite the tip of the pouring opening is articulated captively on the lid by means of a pivot axis and / or can be latched onto the lid with a latching device in the open state.
  • Known opening devices of this type have a closure flap in the region of a pouring opening with a handle which is connected to the closure flap via a tie bar. For opening, the user grips the handle and pulls the closure flap up along the weakening line along a line of weakness, so that the closure flap opens the opening and the filling material can be poured out.
  • Opening devices are known in which the closing flaps can be torn off completely and can therefore be lost with disadvantage. Considerations have already been made to hold the flaps over a flap, but then it is often difficult to insert them into the torn pouring opening, but at least it is hardly guaranteed that they will close properly.
  • the invention is therefore based on the object of providing conventional packs with improved opening devices which, on the one hand, can be opened more easily, the closure flap preferably being kept open, in order nevertheless to be pushed back into the opening in a defined position for reclosing, and for to guarantee the manufacturer economical production.
  • the handle is connected to the central region of the lid via a hinge. If the user pulls up the wear flap to open the pouring device, it initially remains captively hinged in an advantageous manner by snap-in devices, because the closure flap is captively connected to the handle and this is connected to the cover via the articulation bend. Due to the connection of the handle and thus also the articulation bend in the middle area of the cover, the anchoring point for the articulation bend is practically next to the locking device for the closing flap.
  • the manufacturer thus finds an economically producible product, because the articulation bend can also be used as a channel for the flowing plastic with which the lid is injected with the opening device.
  • the plastic is then introduced via the center of the lid, ie outwards from the central area, so that, as is known better spray products are created because all radial flow paths are practically the same length from the center to the outside.
  • the articulation bow is attached to the surface of the cover next to the snap-in device.
  • the articulation arch thus protrudes a little from the surface of the lid, the stackability of the liquid pack is not impaired by this.
  • the articulation bow can be designed in the form of a band and, after the cover has been sprayed on, can be folded over to the level of the cover while it is still plastic. This again creates a flat lid with opening device, handle and articulation bow, in which essentially no parts from the outer contour, i.e. projecting outward beyond the level of the cover. One pack can be stacked on top of the other.
  • the latching device has a nose which is attached to the cover in its central region and is connected to the articulation arch via a connecting web.
  • the closure flap can be latched onto the cover in the open state and kept open. This facilitates handling and pouring with the pack. Opening is also facilitated in particular by the connecting web, because the nose is pulled up when the handle is torn up and when the articulation bend is raised so that the latching bead of the latching device can be guided behind the nose and come into hooking engagement with the nose and are held in it can.
  • the locking bead lies in the outer or upper level of the closing flap and protrudes somewhat beyond it in a bead-like manner.
  • an attachment is formed on the annular handle at the top and rear. This is in no way necessary and is not even desirable in many embodiments, which is why tools are sometimes provided to prevent it from remaining on the handle. On the other hand, it does neither damage the appearance nor the function and shows in a characteristic way how the plastic is supplied via this approach when manufacturing the packaging. If you imagine the injection mold, then the channel in the area of the attachment represents the only inflow channel for the plastic to form the cover.
  • the hot thermoplastic material flows from above and behind in the manufacture of the cover, thus forming the annular handle on both sides (front and rear), so that a large part of the plastic material through the articulation bend in the central region of the cover and from there radially over the Flow paths to its edge; while a further portion of the liquid plastic flows into the area of the opening device from the mentioned approach to the front via a pull strip, because a little more plastic is required to form it than for the smooth cover walls.
  • Both the pull bar between the handle and the closing flap at the front as well as the articulation bend between the handle and the central area of the lid at the back represent flow channels and are at the same time force guide parts for the correct opening, holding, articulation and reclosing of the opening device after the spraying process and shaping the lid with the opening device.
  • the cover 8 made of plastic without a carrier material is injection molded with the pouring device, generally designated 22, with the closure flap 17.
  • the closing flap 17 is articulated captively by means of a pivot axis 28. The closure flap 17 can be latched to the cover 8 in the open state with the latching device generally designated 29.
  • the cover 8 molded on the upper edge 9 of the tube 1 in this way has four corners in plan view, as can clearly be seen in FIG. 3, a pouring edge 13 on the (here called) "front" corner 12, the corner 12 completely encircling, is injected. From the outside you can also clearly see the handle 14 with tie bar 15, which is formed at the front near the cover corner 12 at the tip 16 on the closing flap 17.
  • the closure flap is injection-molded onto a recess 20 along the weakening line 21 on the collar 18.
  • the depression 20 is located in the lower or front area together with the pouring device 22, while the outer or upper wall area 24 of the cover 8 is provided above or behind the rear wall 23.
  • the larger area of the lid 8 is taken up by the upper wall panel 24 which, when the handle 14 is folded over, serves as a standing and supporting surface for the next pack above when stacking, storing and transporting.
  • the articulation axis 28 described with the latching device 29. This is located in the region of the rear wall 23 at the transition from the surface of the lid 8 or the top thereof Wall panel 24 to the recess 20.
  • the articulation axis 28 is only as wide as the distance between the lines of weakness 21 ending at the middle region 2 of the lid 8, for example 8 mm in a 1-liter milk packaging.
  • a locking bead 32 is formed in the form of a sprue, on the side of which facing the closing flap 17 a small shoulder is formed.
  • a nose 34 which points downwards and can engage the shoulder of the locking bead 32.
  • a reinforcing rib 37 supports the nose 34 against the rear wall 23 and reinforces the nose which projects from the rear wall 23 to the closing flap 17.
  • an articulation bend 3 is formed thereon, which can be designed in the form of a web like the drawbar 15, but in the side view of FIGS. 1 and 2 it is designed in an arc shape and at the rear end (in 1 and 2 on the left) in the central area 2 of the cover 8 at 4 is connected to the upper wall panel 24 thereof.
  • the articulation bow 3 is connected to the nose 34 via a connecting web 5, so that when the handle 14 is pulled up in the direction of the arrow 6, the nose 34 is also bent up in the direction of the arrow 6 while deforming the reinforcing rib 37.
  • the handle 14 is provided with an attachment 7, which is integrally formed when the cover 8 is injection molded together with the pouring device 22, because this attachment 7 serves as the flow or inflow of the liquid plastic material from the injection molding machine into the cavities to form the cover with pouring device 22.
  • the snap-in device 29 operates after the pouring device 22 and the exposed pouring opening 27 are torn open in such a way that the closure flap 17 is pivoted about the articulation axis 28 in the direction of arrow 6, the nose 34 being pulled up by the connecting web 5 and the shoulder of the locking bead thereby being behind the nose 24 can snap into place. So that the closure flap with attached and somewhat deformed handle 14 with tie bar 15 and articulation bend 3 is locked in the open position.
