Definitions
- the invention relates to a closure for closing and reclosing a bag, having a strip which can be laid around a shirred neck of a bag and which can be closed to form a closed closure by means of two detachable connection points arranged approximately at the opposite end regions of the strip. and with a tab which can be lifted out of the strip and which can be placed around the gathered neck for closing and can be inserted into the opening formed by lifting out the tab.
- a closure is known from EP 1 209 091 A1.
- the flap in its entirety is releasable.
- the strip When closing, the strip is placed around a gathered neck of a bag and, for example, closed by welding in the region of the opposite end regions of the strip. In this case, the strip is welded in such a way that one end region of the strip is welded to an end region of the removable tab which is opposite this end region.
- the flap When opening the closure for the first time, the flap is cut out of the strip in its entirety, but remains firmly connected to the end of the strip to which it was previously welded. In other words, the weld joint between the one end of the strip and the tab is stronger than the perforated connection along a desired bridge between the tab and the strip.
- the separated-out tab remains in contact with the strip via one spot weld and extends approximately in the longitudinal direction of the strip and away from it.
- this assembly is placed approximately U-shaped around the shirred neck and the tab is inserted into the opening, which stood ent stood by their separation. So that the tab does not move out of the opening again by itself, corresponding contouring is provided.
- N half of this closure is that the first closing, which is usually carried out by the manufacturer ist ⁇ , must be paid exactly to ensure that the weld is so that the one end of the strip with the distal end of the approximately centrally arranged Sciwennba ⁇ lasche is connected. Furthermore, forcibly when first opening the separation takes place the entire tab. This results in a relatively elongated structure which, if the closure is no longer needed because, for example, the bag is no longer to be closed, is correspondingly bulky. It also requires some skill to create these structures for re-closing. Furthermore, a bulky structure is laterally beyond the bag neck after resealing.
- the applicant's DE 197 33 294 C2 discloses a bag for closing and sealing, in which the two layers of earth 1 " 1 of the strip are welded over one another by a welding strap After the tearing open in the area of the welding point, an opening is created at the ends of the strip This is achieved by the material being pressed in the region of one strip through the welding stamp in the region of one strip in the direction of the other strip and fused therewith.
- the object is achieved in that the tab extends between the connection points and that the tab in the region of one of the connection points fixed, so it is not detachable connected.
- the strip When the closure is first closed by way of the fixed connection points, the strip is closed, for example welded, by the two connecting points arranged at the opposite end regions. Because the removable tab extends between these connection points, this connection does not take place in the region of the releasable tab. This has the consequence when the closure is opened for the first time by severing the connection points, that the tab is not yet cut out or dissolved out.
- the closure may be in the form of strip as it is, so be disposed of in the original length of the strip.
- the result is a structure that is very tight and compact around the neck of the bag, since the total length of the strip has not changed.
- the closure can be used as in reclosing.
- a bag for example a freezer bag
- the closure can be used as in reclosing.
- both options are open, even in the industrial sector with the machine application and the permanent connection when first closing, for example.
- the bag At a manufacturer of sliced bread, or even in a Einzel ⁇ consumer or Diab Heilller or -beheller the bag. This considerably increases the manageability and use of such a closure.
- the tab is also strip-shaped.
- This measure has the advantage that after pushing out the tab, an approximately V-shaped structure of two strip-like elements is formed, which can be easily brought from one side to the shirred bag neck for resealing and pushed. All that remains is to insert the one protruding end of the tab into the opening in the strip. This can be done by skilled persons even with one hand, ie with the other hand can, for example, the bag or the shirred bag neck are kept.
- the tab is provided at the longitudinal edges with projections.
- the shirred bag neck has the tendency to expand again after the closure has been applied; this is prevented by the protrusions, since correspondingly negatively contoured protrusions are present in the opening, whereby an accidental slipping out of the flap is inhibited.
- this projecting portion of the tab needs to be rotated only about 90 °, which then the projecting beyond the opening part can be easily removed again. This also opens up a multiple resealing and opening of the faucet.
- a hole is present in the strip.
- This measure has the advantage that it creates a transport or feeding feature into which appropriate fingers or pens can enter.
- closures are usually made as an endless belt and must be brought in accordance with the position and synchronized to the neck of the bag, which is to be closed with a separated out of this band strip.
- This hole now opens a simple mechanical measure of position-based automated first-time application of the closure at the original manufacturer.
- the hole is present at the end of the tab, which is.
- the tab which is.
- This measure now additionally has the advantage that the user is provided with a starting point and an orientation aid through the hole, where he must apply his finger in order to press the tab out of the strip.
- the strip is provided with wedge-shaped tapered side edges.
- This embodiment can be combined without or with the configuration of additional projections on the longitudinal edges.
- the tab is relatively narrow at the end at which it can be released, and only then the projections are present.
- the projections on the side facing the end of the tab which is fixedly connected to the strip are provided with an edge which blocks removal of the tab from the opening.
- the projections on the side, which face the leachable end of the tab are provided with bevelled edges, which facilitate insertion into the opening.
- the tab widens wedge-shaped from the detachable end to the firmly connected end and has an undercut in the region of the firmly connected end.
- 1 is a plan view of a closure in the form ei ⁇ * .es strip before an initial application to a Beu ⁇ tel,
- FIG. 2 shows a side view of a bag in the region of its shirred neck around which the strip shown in FIG. 1 is placed and closed
- FIG. 3 is a section along the line III-III in Fig. 2,
- FIGS. 1 to 3 shows the strip of FIGS. 1 to 3 after the closure has been opened again and removed from the neck of the booty Is, and in which the flap has already been released or pushed out,
- FIG. 5 shows a situation in which the strip shown in FIG. 4 is again applied to the bag of FIG. 2 in the region of the neck which has been gathered, for reclosing.
- Fig '. 6 shows a further exemplary embodiment of a closure according to the invention, in a state in which it is still formed as a band of several contiguous strips,
- FIG. 7 is a view similar to FIG. 2 of a bag neck to which the closure of FIG. 6 is applied; 8 is a section along the line VIII-VIII in Fig. 7,
- Fig. 9 shows another embodiment of a closure with a wedge-shaped tab
- Fig. 10 is a perspective view of a bag neck to which the closure of Fig. 9 is applied.
- FIGS. 1 to 5 A closure shown in FIGS. 1 to 5 is indicated in its entirety by the reference numeral 10.
- the closure 10 consists of a rectangular strip 12 of a thermoplastic material.
- the strip 12 has two opposite end regions 14 and 16, on each of which a later connection point IS or 20 is indicated.
- the closure After being applied to a bag, as shown in FIG. 2, the closure is connected to a closed closure via these end-side connection points 18 and 20, for example by welding, as will be explained below.
- connection points 18 and 20 Between the connection points 18 and 20, so without reaching these connection points, a tongue-like tab 22 is formed.
- the tab is pre-characterized by a perforation 24. This perforation 24 thus forms a predetermined breaking point of the connection between tab 22 and strip 12.
- the two longitudinal edges 25 of the tab 22 are formed so that a plurality of prongs 27 are outlined.
- an approximately square hole 28 is provided in the strip, which is formed, for example, by a stamping operation.
- edge of the hole 28 is thus formed by the right outer end of the tab 22.
- the tab 22 is relatively narrow and has no teeth 27 on.
- FIG. 2 shows a situation in which the strip 12 is applied to the shirred neck 34 of a human IP 12, from the viewpoint of the observer from above or from the corresponding side, folded around the latter and via a spot weld 36 is connected to a closed closure, as can be seen in particular from the sectional view of FIG. 3.
- the strip 12 is arranged in such a way that the end regions 14 and ⁇ d 16 along one side, namely the same side of the strip 14 together.
- connection points 18 and 20 extend between these connection points 18 and 20, ie does not touch them.
- Fig. 3 is indicated by a double arrow, the angular range 38, extends over which the pre-punched tab.
- Fig. 3 it is shown that the two end portions 14 and 16 end at the same height, one can also perform so that the one end portion of the other slightly surmounted so that a Ansatzhiife is created for the consumer to the closed closure again to open.
- connection points 18 and 20 thereby clearly recognizable material changes that can serve as a clearly recognizable Clearöffungsmerkmal.
- Fig. 4 a situation is shown in which the tab 22 has been separated from the strip 12 as far as possible along the perforated line and raised. Once again, it can be clearly seen that because of the end 26 with the permanent connection, the tab 22 can only be lifted out of the strip 12, but can not yet be completely removed.
- This V-shaped structure which is now indicated in FIG. 4, can be reattached to the gathered neck 34 of the bag 32 for reclosing, as shown in FIG.
- the prongs 27 along the longitudinal edges of the tab prevent accidental slipping out of the tab 22 from the opening 30th
- the shirred bag neck 34 exerts a pressure which is the Ab ⁇ section of the tab 22, which through the opening 30 geunter- ben, presses in the relatively narrow end portion of the opening 30.
- the two protruding ends of the U-shaped bent strip can be moved toward one another slightly, the pushed-through region of the flap 22 is rotated approximately 90 ° and thus simply pushed out of the opening 30 again.
- This process can also be repeated several times.
- FIGS. 6 and 8 show a further embodiment of a closure 40 according to the invention.
- FIG. 6 shows that the individual strips 42 are produced in an oriinary manner as an endless belt 40.
- Each individual strip portion has a pre-perforated tab 44 and also has the corresponding punched hole 46.
- the tab 44 is provided along its longitudinal edges with hooks 48 which hsiransn an unintentional opening of the shutter on the Wieds- sron as shown in FIG.
- the Eaken 48 have a the fixedly connected end 47 facing edge 45 which is approximately perpendicular to the longitudinal axis of the strip 42.
- the detachable end 45 facing edge 53 is chamfered and serves as an inlet slope.
- the overlapping end 51 is grasped, lifted and then the weld is torn open.
- the latter is likewise designed as a rectangular, elongated strip 62.
- the pre-perforated flap 64 is provided with wedge-shaped flared lateral edges 66 and 68.
- the tab 64 widens from the front end 65, which is to be lifted, in the direction of the end 62 fixedly connected to the strip 62.
- an undercut 70 is provided which extends approximately perpendicular to the longitudinal axis of the strip 62.
- Fig. 10 a situation is shown how the strip 62 is placed around a shirred neck 74 of a bag 76.
- the Tab 64 is inserted into the opening 73 and pulled so far through this, that the undercut 70 has passed through the opening 73. This is possible due to the flexibility of the material. This results in a very tight and tight-fitting closure that seals the bag 76 in the region of its gathered neck 74 tight.
- the undercut 70 locks off the tab 64 from the opening.
- Fig. 10 is indicated by an arrow that the user pulls the threaded into the opening 73 tab 64 in this direction, and indeed until it has passed along with their undercut.
- This process can be made easier for the user by holding the two outer ends of the strip attached to the gathered neck 74, for example, between the thumb and forefinger.
- closures described above can also be used in each case in such a way that they are not firmly connected, for example welded, by a mechanical manufacturer to an original closure at the two opposing ends, but they can also be used exclusively in this way. as they are handled in the reseal described above.
- the strips 12, 42 and 62 previously described to a user as individual pieces or as goods that can be separated from a band. This takes place when, for example, the user himself individually fills a bag, for example a freezer bag, that is to say the consumer for the first time fills and closes such a bag for the first time. Then he manipulates it so that he pushes the tab out of the bag, for example. As shown in Fig. 4, the closure applies to the shirred neck, threading the tab into the opening formed by lifting the tab and then pull the closure ,
