Description

The invention relates to a container with a container wall penetrating fill opening with a sealing strip is closable, the first, attached to the container Section and a closure portion which to the Container wall is pivotable.

The invention further relates to a method for attachment of a sealing strip on a container with a container wall penetrating filling opening through the sealing strip is sealable, the closure strip is attached locally to the container so that it has a free Closure section forms the sealing over the filling opening can be laid.

A container is known from EP 0 456 011 A1, in which in addition to attached a still open sealing strip to the filling opening is. After filling, the filling opening is through the sealing strip locked. The fastener strip can be before or after the complete completion of the container next to the filling opening be attached. Before filling and closing the The closure strip is in a container undefined position. It can, for example, from the container protrude and its further handling until filling and Disrupt closure. This applies in particular if the Sealing strips attached before the container is finished becomes.

It is the object of the invention to provide a fastener strip to attach a filling opening of a container such that it its further handling up to the closing does not interfere.

The object is achieved in the container in that the closure section has a holding part with which he in one of the Container wall approximate position is held.

The object is achieved in the method in that after locally fastening the closure section into one of the container walls brought to approximate position and in this position is held.

This has the advantage that the sealing strip at any time before filling the container, in particular can be attached during its manufacture. The further handling of the container, for example when passing through a manufacturing machine is not hindered.

The closure section can be in different ways, for example by bending the fastener strip, near the Container wall are brought. There are various of the container wall approximate positions. The closure section can for example be adjacent to a continuous Container wall, for example next to the filling opening, are without this to cover. It can take place in an advantageous embodiment which also lie so that it covers the filling opening without it to seal tightly. It is important that the closure section does not protrude from the container wall.

The closure section can be in various measures its position closer to the container wall can be held. It is possible, for example, rigid for the fastener strip Use material so that the closure section after bending maintains the position approximated to the container wall. It is also possible to provide a holding part that the Closure section holds in place.

The locking section is only temporarily in position held and can be easily released from it. This is required if it is finally over the Filling opening should be placed to seal this close. It is also required if it is above the Filling opening lies without sealing it, and the Filling opening for filling should be exposed.

The method can be further developed in an advantageous manner that the filling opening through the closure section is not pre-sealed in a sealed manner, then by lifting off the closure section opened again and sealed after filling becomes. The closing section passes through the pre-closing in a position in which he will handle later does not bother. It also protects the inside of the container from the Penetration of dirt particles. This is especially so important if the container is not immediately after its completion is filled.

In this embodiment, the closure portion before Filling lifted from the filling opening. This is then due Disinfect the inside of the container and fill the contents free. The locally attached fastener strip is when lifting of the closure portion is not detached from the container. After this The closure section is filled again via the filling opening placed so that it is covered. Then he will be with the Container wall connected so that the filling opening is germ-tight is closed.

The inventive holding part can be designed very simply, since it is only intended to hold the closure section temporarily. It is designed in such a way that the closure section is slightly open its temporary position can be released again.

In an advantageous embodiment, the holding part has a holding surface and the container has a stationary counter surface between which a holding connection can be made. It is here advantageous if the holding connection is a clamp connection or is a latching connection. Such connections are constructive easy to manufacture. They are sufficient to cover the closure section to temporarily hold in the desired position.

In an advantageous embodiment, the holding part by a Approach of the closure section formed. This is one particularly simple design of the holding part possible because of Approach only needs to be an extension of the holding part and can consist of the same material. The approach needs to be only a small size because of the ones he held Closure section do not apply any special forces.

In an advantageous embodiment, the holding connection is made by Bending the neck made. For the approach or for the entire closure portion is a suitable material, for example Metal that uses the desired bending properties Has. This allows the holding connection in particular be manufactured in a simple manner.

In an advantageous embodiment, the holding surface on the Arranged on top or on the bottom of the neck. For the holding connection is usually sufficient if the holding surface has a certain size and can be applied to the Supports the counter surface. Such an arrangement is usually also sufficient if on the holding surface in a lateral direction is acted upon.

1 shows an embodiment of a container 1, which is composed of a jacket 2 and two end walls 3, 4 is. The two end walls 3, 4 are inserted into the jacket 2 and heat-sealed with it to make it liquid and germ-proof connected. The end wall 3 forms the lid and the end wall 4 the Bottom of the container 1. The peripheral contour of the end walls 3 and 4 is circular. The jacket 2 and the end walls 3 and 4 thus form the container walls of the container 1, which is a cylindrical Enclose interior 5.

The end wall 3 has a frame 6, around which the jacket 2 below Formation of a flange 7 is rolled around. It will be one of the end wall 3 protruding container section made, the End wall 3 surrounds as edge 8. The end wall 3 forms together with the edge 8 has a space 9 which is open towards the edge 10.

The end wall 4 is connected to the jacket 2 in the same way like the end wall 3.

The interior 5 is accessible through a filling opening 11. This Filling opening 11 is arranged in a container wall 12 through the end wall 3 is formed. You can through a fastener strip 13 are closed. In the illustrated in Figure 1 Position is the sealing strip 13 over the filling opening 11 placed so that the container 1 is closed. By tearing it off of the closure strip 13, the filling opening 11 can be exposed become. It also serves as an emptying opening.

As packaging material for the jacket 2 and for the end walls 3 and 4 paper or cardboard is used. If necessary, you can further layers, for example one or more plastic layers or a metal foil for the packaging material be available. These additional layers serve as Barrier layer. Plastic layers are required to the to produce the above-mentioned heat seal connection. For the closure strip 13 a flexible metal foil is used, the on the side facing the container wall 12 additionally with is provided with a heat-sealable plastic layer.

In Figure 2, the closure strip 13 is flat, that is not curved shown. It contains a first section 14, a closure section 15 and a holding part 16. The holding part 16 consists of two approaches 17. They are designed as prongs 18, which extend the closure section 15 and each in one Discontinue tip 19. The sealing strip 13 has on the later the edge 8 of the end wall 3 facing one of the Rounding the edge 8 - and the flange 7- adapted contour 13a.

In the position shown in Figure 1, in which the filling opening 11 is sealed, the sealing strip 13 is in the Area of the holding part 16 with its teeth 18 bent upwards, so that they rest against the inside 20 of the edge 8.

The closure strip 13 does not have this position from the beginning. Rather, it is first attached locally to the container 1, then the container 1 is filled and finally through the Sealing strip 13 sealed.

In the following, FIGS. 3 to 9 illustrate which ones different positions of the fastener strips 13 between local fastening and sealing can.

As can be seen from Figure 3, the end wall 3 is in the jacket 2 used and in the region of the edge 8 liquid and germ-tightly connected to it. The bottom is what is not from Figure 3 can be seen, not yet used in the jacket 2. Of the Container 1 is thus only partially completed.

Now the closure strip 13, which is shown in FIG. has a flat shape, locally attached to the end wall 3. This happens in that the first section 14 in the area of Stitch 21 with the outer surface 22 of the container wall 12 is connected. The connection at stitching point 21 is made by heat sealing. For this, the plastic layer already mentioned above of the closure strip 13 and a not shown, plastic layer present on the surface 22 of the end wall 3 used.

After fastening the first section 14 to the stitching point 21 the closure section 15 takes a more or less random Position on. As can be seen from Figure 3, the closure portion protrudes 15 from the surface 22 of the container wall 12, the front part protruding beyond the edge 10 of the edge 8.

As can also be seen from FIG. 3, there are 18 in the teeth several holding surfaces 23 and 24 available. The holding surface 23 is on the underside 25 and the holding surface 24 at the tip 19 of the Point 18 arranged. Here, the tip 19 forms a front Edge 26 of the prong 18.

The inside 20 of the edge 8 is used in the area by the Holding part 16 of the closure strip 13 is covered as Counter surface 27.

After the fastening of the closure strip 13 locally Locking section 15 around the first, locally attached Section 14 pivoted towards the filling opening 11. After the pivoting he takes that shown in Figure 4, the Container wall 12 approximate position. The point 18 becomes bent here so that it lies parallel to the protruding edge 8.

As can be seen more clearly from FIG. 8, this makes one Holding connection between the holding surfaces 23, 24 and the counter surface 27 manufactured. The on the bottom 25 of the prong 18th lying holding surface 23 is pressed against the counter surface 27. This creates a clamp connection that is sufficient to the Closure section 15 in its approximation of the container wall 12 Hold position.

The holding surface 24 formed by the tip 19 of the prong 18 is a profile protruding from the inside 20 of the edge 8 28 opposite. This profile 28 is, as well as closer further profiles 29 of the edge lying on the edge 10 8, continuous in the circumferential direction. Would you like the locking section 15 move upward away from the container wall 12, so would butt the tip 19 against the profile 28. Between the Tip 19 and the profile 28 is thus a snap connection educated.

In Figure 9, the position of the prong 18 is opposite that in Figure 8 position slightly changed. The one on the Underside 25 of the prong 18 lying holding surface 23 is not effective. The tip 19 of the prong 18 is supported against the Profiling 29 from.

The holding surface 23 and the holding surface 24 each extend individually to the closure section 15 in the container wall 12 to hold the approximate position. This applies to both in Figure 8 as well as for the position shown in Figure 9. The Holding connection would also be maintained if in FIG. 8 the holding surface 24 would protrude to the right, that is from the Counter surface 27 would be bent away.

As can be seen from FIG. 4, the closure strip is 13 completely recorded in room 9. It does not protrude above that Edge 10 beyond. Therefore the further handling of the Container 1, in particular during the further course of production, not bothered. The closure section 15 covers the Filling opening 11, this is therefore not pre-sealed. In the further course of production, the not completed Container 1 to different workstations, in which the end wall 4 used as the bottom and with the Sheath 2 is connected. This can happen without the Filling opening 11 must be exposed. The closure strip 13 then maintains the position shown in Figure 4 until the Container 1 completely completed by inserting the bottom and is fed to a bottling plant.

If in a manufacturing process not described here a tool to be inserted into the filling opening 11 can the shutter portion 15 are moved away from it to the Expose insertion of the tool. If the tool again is led out of the filling opening 11, this can again pre-closed and the closure section 15 in the in Figure 4 shown position are brought.

In another embodiment, not shown, the Locking section, deviating from Figure 4, in the opposite Direction, i.e. away from the filling opening, swiveled until he assumes a position closer to the container wall. The The filling opening is then not covered, but is exposed to for example, during the further manufacturing process Insert tool. The tops of the tines lie down against the inside of the edge and form a retaining connection. Also retains this embodiment, not shown the closure section is the position approximated to the container wall at until it is fed to a bottling plant. The closure section can, for example after completion of the container, naturally also released from this position and into that in FIG. 4 position shown when the filling opening up to be covered for filling.

It is also possible to cover 13 only in a later Production stage, for example, only after the onset of Bottom or only after complete completion of the container, to be attached locally.

The closure section 15 can be made from the container wall 12 approximate position by a suitable tool in simple Way to be solved. As can be seen from FIGS. 4 and 8, it does not lie over the entire surface of the container wall 12, but instead leaves a small gap, especially with its longitudinal edges. As For example, a hook-like element is conceivable as a tool engages under the longitudinal edges of the closure portion 15 and levered this up. The closure portion 15 can then in Figure 5 take upright position shown in the the filling opening 11, for example for filling, is completely free lies.

In Figure 6 the filling is shown schematically. Here is a filling pipe 30 through the filling opening 11 into the Interior 5 of the container 1 out.

After filling, the closure section 15 is again over the Filling opening 11 pivoted toward the container wall 12 and sealed to the container wall 12. This is in Figure 7 shown. The sealing connection is made by manufacturing a heat seal seam 31, which the filling opening 11 along its Circumferentially surrounds.
