Definitions
- the present invention relates to a closure device for a bag with two closure strips having interlockable profile strips which can be opened and closed by a slider, wherein the slider is movable in the longitudinal direction of the closure strip, the closure strip U-shaped embraces and two side walls and a has the connecting portion connecting the side walls, wherein at the connecting portion an at least partially engaging between the closure strip projection for opening the closure strip and spaced from the protrusion two externally applied to the closure strip plungers are provided for closing the profile strips.
- WO 2013/192287 A2 discloses a bag with a closure device which has two profile strips which can be opened and closed via a slide.
- the slide has for this purpose a web-shaped projection which can be inserted between the profiles of the closure device. Spaced apart from the projection, two thrust pieces are provided to open the closure strips in a direction when the slider is moved in one direction and to close them in the opposite direction.
- a disadvantage of this closure device is that the user hardly recognizes whether the closure strips are open or closed when the slider is in the center position, because the distance between the closure strip is very low both in the open and in the closed position and hardly achievable with the eye be recognized, which makes handling difficult.
- the sealing of the closure strip is inadequate and leakage may occur, especially with liquids in the bag.
- the closure device comprises on the slide at a connecting portion a projection for opening the closure strip.
- a projection for opening the closure strip fen seen in plan view of the connecting portion has a wedge-shaped portion with two alsspr Schwarzenden side walls.
- the closure strips can better attach to the projection, which leads to fewer gaps and thus to an improved seal.
- the opening width can be widened by the wedge-shaped contour, so that the user recognizes by a view of the closure strips on opposite sides of the slider, which side is the opening side and which is the closure side.
- the projection has a maximum width of more than 1, 5 mm in plan view.
- the projection on the side opposite to a tip has a width of more than 1.7 mm, for example between 1.8 mm and 2.5 mm.
- the closure strips are held on the opening side at a distance of about 2 mm, which is visible to the eye and thus improves the handling compared to prior art slides, in which the closure strips are opened only by about 1 mm.
- the projection has a length in the sliding direction of more than 3 mm, for example between 4 mm and 6 mm.
- the projection can taper in a wedge shape with a section and open the profile strips during a movement with gentle pressure.
- pressure pieces are preferably provided, which are arranged in the sliding direction less than 4 mm, in particular between 1 mm to 3 mm.
- These plungers are on the outside of the profile strip and press together with a sliding movement in the closing direction, the short distance to the projection ensures a good seal.
- the connecting section can also cover any gaps if the projection is provided within the connecting section as seen in plan view.
- the projection may have a trapezoidal section as viewed in plan view with end walls converging towards the end.
- the projection in plan view is approximately diamond-shaped and can be mounted during assembly on the closure strip from both sides.
- the side walls of the trapezoidal section can be less pointed than the side walls of the wedge-shaped section.
- Two webs are respectively provided on the side walls of the slide, in particular at opposite ends in the sliding direction, which project inwards and are guided along strips of the closure strips.
- the slider is secured against lifting from the closure strips, and also an exact guidance is ensured in a direction perpendicular to the sliding direction.
- the handling of the closure device is further simplified when at least one mark for indicating the opening or closing direction is attached to the slider.
- a corresponding marking can be provided as an arrow, pictogram or test.
- the closure device is preferably provided on a bag for storing food, in particular of a transparent plastic film.
- Figure 1 is a perspective view of a bag with a closure device according to the invention
- Figure 2 is a sectional view through the closure device of Figure 1;
- Figure 3 is a bottom view of the slider of the closure device of Figure 1;
- FIG 4 is a plan view of the slider of the closure device, and Figures 5A to 5C show several views of a slider with a modified projection.
- a bag 1 comprises two side walls 2, which are connected to one another at a bottom 9. The side walls 2 are further connected by two seams 8 on two opposite sides and have an opening 3 on one side.
- a closure strip 4 or 5 is fixed, in particular glued or welded.
- the closure strips 4 and 5 are formed as extruded plastic profiles, which are fixed to the edge side of the side walls 2.
- a slider 6 is movable between two end positions in order to open or close the closure strips 4 and 5. At opposite ends, the closure strips 4 and 5 are glued or welded together.
- FIG. 2 shows the closure device in the region of the slide 6.
- the slider 6 comprises two side walls 1 5 and 1 7, which are connected to one another via a connecting portion 1 9 and the two closure strips 4 and 5 engage around in a U-shape.
- At the end of the side wall 1 5 is an inwardly projecting web 1 6 and at the end of the side wall 1 7 an inwardly projecting web 1 8 is provided, the slide 6 together lead to strips 1 3 and 14, which on the closure strip 4 and 5 are formed.
- the slider 6 is not detachable from the closure strips 4 and 5 in an upward direction in FIG. 2 and thus guided exactly perpendicular to the sliding direction.
- the closure strip 4 comprises two hook-shaped profile strips 1 1, which are engageable with two hook-shaped profile strips 1 0 on the closure strip 5.
- the hook-shaped profile strips 1 0 and 1 1 pressed to each other and can lock together by the hook shape.
- an inwardly projecting guide strip 1 2 is still formed, which prevents the upper hook-shaped profile strip 1 0 can escape on the closure strip 5 upwards.
- both profile strips 1 0 positively locked to the two profile strips 1 1.
- other geometries for the profile strips 1 0 and 1 1 can be used to detachably connect them together.
- a projection 20 is integrally formed on the connecting portion 1 9, which engages at least partially between the two closure strips 4 and 5, in particular above the profile strip 1 0 and 1.
- the projection 20 is a kind of separating nose, which separates the closure strips 4 and 5 when moving.
- the slider 6 is in a view of the projection 20 on the
- the projection 20 is disposed entirely within the connecting portion 19 and has a wedge-shaped portion with a tip 21 and two spreading side walls 22.
- the angle of the side walls 22 may, for example, in a range between 5 ° and 25 °.
- At the opposite side to the tip 21 side 23 of the projection 20 is concave. It is also possible to design the projection 20 without curvature at the end or to provide at the end of another portion which adjoins the wedge-shaped portion.
- the width of the opposite side to the tip 21 23 is in a range between 1, 8 mm and 2.5 mm, so that when you open the closure strips 4 and 5 are kept visible at a distance.
- two pressure pieces 24 which protrude inwards and the closure strips 4 and 5 façadeammendrü- to close them.
- the pressure pieces 24 are arranged only at a small distance from the tip 21 of the projection 20, for example, between 1.5 mm to 3 mm, so that the closure strips 4 and 5 substantially form-fitting exactly by the plungers 24 and the projection 20 are guided and only small gaps arise.
- the inwardly projecting webs 1 6 and 1 8 are arranged in each case at opposite ends of the slider 6 in the sliding direction.
- the gap between the inwardly projecting webs 1 6 and 1 8 can be in the range between 0.7 and 1, 4 mm.
- Trained as a one-piece plastic part slider 6 can also according to Figure 4 on an upper side of the connecting portion 1 9 have a mark 30 for identifying the opening or closing direction.
- the marker 30 can be provided by shaping or by color deposition. Instead of an arrow, other markings or words can be provided.
