Definitions
- the present invention relates to a sealing zipper with the features of the preamble of claim 1.
- Zippers also sealing with slide are known. They are to thread for closing or are connected on one or both sides, the slider is constantly connected to the zipper halves. To close, the slider must be pulled along the two zipper halves, using two outer flanks to engage the teeth of the zipper. To open the slider must be guided along the zipper and separates with its central, wedge-shaped heart teeth. Through molded sealing elements has been tried many times to produce sealing zippers.
- a waterproof zipper consisting of two zipper halves, which are encapsulated with a thermoplastic elastomer, which rests in each case as a profile-like coating on the abutting edges of the zipper tapes, the profile-like coatings sealingly abut each other with the zipper closed.
- the zipper has a port for the slider, which is formed as a circumferential bead around a heart area.
- the port is gasketed and has a transition to the coating profile of the zipper, which is oversized so that the sides of the zipper exert greater lateral pressure to seal the port.
- EP-A-0 900 532 and US-A-2,910,754 show zips in which the teeth are present as pairwise engaging elements respectively disposed below and above the zipper belts and interconnected by holes in the belts. Between the engagement elements extend along the zipper tapes sealing lips or sealing elements.
- the vertical and horizontal seals must be sealed at the same time, which is achieved by over-pressing the sealant at the pressure point.
- This version is problematic when opening the zipper, ie separating the bands with an inner sealing lip and externally arranged fixed coupling elements.
- the tip of the slider heart presses on the first element, which is then pressed on the next, which blocks the zipper.
- the object of the present invention is to provide a sealing zipper in which a sealing closure is ensured and which can be easily and safely opened without blocking the zipper.
- a sealing zipper consisting of slide, sealing end piece and two bands, each edge sealing surfaces formed as a molded part coupling element pairs, wherein the coupling elements are arranged above and below the respective peripheral sealing surfaces and these in turn correspond to the coupling element pairs of the other band, wherein the sealing end designed as a port has at least one guide device for the slider, in addition to the webs, in its front webs adjoining the zipper tapes before the last coupling element pair.
- the guide device extends on the two, adjoining the last coupling members webs of the port, each on a zipper tape on and on the other zipper tape under the edge sealing lip of the corresponding zipper tape.
- On the opposite side of each web is a bulge, in which pushes the corresponding guide means.
- the distance shown from the tips of the coupling members to the corresponding sealing lip of the same zipper tape substantially corresponds to a preferred projection of the guide means via the sealing lip in the direction of the interior of the sealing piece.
- the guide device and the bulge as well as the horizontal sealing lip are pressed sealingly against one another by the slide plates and slide edges.
- the formed surface of the webs, zipper tapes and sealing lips is according to the invention larger than the area formed in the slide between the slide edges, whereby this seals by compression.
- the profile of the zipper tapes in the preferably sprayed on, glued or welded sealing piece continues to run in a straight line substantially parallel to the webs of the sealing piece.
- the zipper teeth are preferably sprayed on, which can be done according to an embodiment of the invention, for example by introducing holes in the zipper tapes.
- the zipper coupling members each have on their upper side preferably a groove, which are introduced during the process of the injection of the teeth on the zipper tapes or mechanically incorporated, such as milled.
- the sealing end piece is applied according to a preferred embodiment of the invention with its webs on the last coupling members of the zipper tapes, whereby the approach anchored to the webs of the sealing piece in the grooves of the last coupling links, whereby on the one hand kinking at this point Ie is prevented and an additional guide for the slider is created, which offers particular advantages in opening the zipper.
- Fig. 1 is a plan view of a zipper and the sealing piece
- Fig. 3 is a perspective view of a zipper
- Fig. 4 is a perspective view of a slider
- Fig. 5 is another perspective view of a slider
- Fig. 6 is a side view of a slider
- Fig. 7 is a plan view of a slider
- Fig. 1 shows an open zipper of two zipper tapes 2, T ', which are provided with coupling link rows 4, which are to be engaged with each other.
- the two zipper tapes 2, 2 ' are connected in the region of the sealing piece 1 with a welding plate 14, on which the sealing piece 1 is applied.
- the Fellermmgs worn 6 can be seen on the left web of the sealing piece 1, which can be seen because of the recess located on the upper right side on the lower right side.
- the coupling links have on their upper side a groove 12 in which engage in the region of the transition from the rows of teeth on the sealing piece 1 of the projection 13 of the webs 5 of the sealing piece, whereby the stability is increased to this point and an additional guide for the slide 7 is created .
- Fig. 2 shows a section through the zipper shown in Fig. 1 in which the guide means 6 can be seen at the top left and bottom right and which when retracting the slide 7 by means of the slide plates and the slide webs in the sealing piece with the sealing lip 3 respectively in the opposite recess 8 are pressed and sealed.
- the horseshoe-shaped, horizontal sealing lips 16 are pressed sealingly against the slide plates 11.
- the guide devices 6 each protrude slightly beyond the sealing lips 3 of the zipper tapes 2 into the interior of the sealing piece 1. In this way, in the closed state of the zipper on the one hand, a vertical seal by the pressing against each other of the sealing lips 3, as well as a horizontal seal by pressing together the two guide means 6, between which the seal 3 of the zipper tape 2 is located.
- FIG. 3 shows a perspective view of a band 2, 2 'equipped with coupling links 4, by means of a partially closed zipper connected by means of a welding plate 14.
- a partially closed zipper connected by means of a welding plate 14.
- FIGS. 4 and 5 show perspective views of a slide on which the slide plates 11 and slide edges 9 are shown.
- Fig. 6 and Fig. 7 is a side view and a plan view of a slider 7 is shown in which the separation of the slide edges 9 along the slider heart 15 is shown.
