Description

Plastic container with snap-on lid, where the art fabric container with an edge bead and a surrounding web is provided and the lid an outer the container edge overlapping ring part, which on the the container edge facing side has a bead ring, which is at Snap the lid under the bead, placing the Ring part of the lid is provided with a tab that via narrow connections on the side that serve as predetermined breaking points gene is connected to the ring part and on the ring part, this interrupting a part of the circumference, near the bead ring the lid is pivotable relative to the container wall steers is.

Such containers, which have any shape, for example round, can be oval or angular, are used for storage and for transporting any goods, including a new Ver Close the container with the original lid light becomes.

In the case of one from German utility model No. 89 04 937.4 plastic container with a snap-on lids are for easy opening one or more axes parallel to the Incorrect breaking points incorporated in the lid. This should Breaks allow opening when the cover is removed expansion of the outer ring part of the lid edge. To be a Easy opening of the container without destroying the break to prevent places, is with the cover snapped into place immediately below the edge of the lid from the wall of the Protruding peripheral web.

In a variant of this known container are two target breaks arranged side by side, between which there is a  Part of the lid edge is located, which is due to a retraction can be used as a kind of grip tab. For the purpose of Opening the container, the grip tab can be gripped and opened conditions, so that the lid then with reasonable force wall can be lifted. Based on the condition of the target breaks can be recognized without any doubt whether the Contents of the container are still in their original condition.

A disadvantage of this container is that the Handle tab and the adjacent area of the ring part at Opening the container is bent relatively strongly, so that a permanent deformation can be the result. This permanent one Deformation can occur when the container is closed again cause leaks at the edge of the container. That is, one more time ger use of the lid, as it is only partially Emptying the container is severely restricted, because with each new opening process another permanent one Deformation can arise.

Another disadvantage of this solution is the bad Leverage of the grip tab can be seen so that the opening process is insufficiently supported. In addition, there is Possibility that the grip tab during transport or again Closing the container is accidentally pressed in and by tearing the predetermined breaking points behind the dec jammed edge. This jamming makes opening difficult NEN of the container very significantly.

A similar construction can also be found in EP-A-0 326 068 forth.

Furthermore, CH-A-672 473 shows a closure for one Plastic container, which is designed such that this safe even if the container collides from a greater height holds. The lid is with a circumferential closure Provide part, which the container wall on the outside this surrounds with a snap. On the outer wall of the closure part is followed by a tear-off tape on which one faces down  sending eyelet is attached. Next to the eyelet is a handle to open weak points on the tear-off tape on both sides of the Handle provided. After tearing the tear tape ver the handle remains on the lid so that it can be opened that can.

So this document shows the same disadvantages as that DE-G 89 06 937.6, which consist in that the lid when Opening is strongly deformed because the wall is compact throughout is trained. That means the wall here too is considerably bent when opened, which is due to the additional Chen handle should be facilitated. Opening the lid without using the handle seems impossible because of a sub gripping the lid edge to open is not possible.

Another disadvantage of this solution is that that the handle protrudes laterally from the lid and thus can be damaged by containers stacked next to each other.

The invention is therefore based on the object of an art To design a fabric container with a snap-on lid so that the lid is particularly light, possibly several times, can be removed and put back on tightly.

According to the present invention, the object is one Plastic container with a snap-on lid at the beginning named type solved in that the grip tab extends at least to the web and with a protruding Grip edge is provided, which covers the web, the Grip tab at least on her from the container wall turned side spaced apart and has ribs running parallel to the container axis, the a stop of the grip tab on the outer surface of the De Form an apron.

The invention now includes a plastic container Cover created, in which the lid is particularly convenient can be removed and replaced without a reduction  the tightness would have to be feared. For the first time NEN of the container only the grip tab is to be grasped and deduct radially from the container wall, so that the Handle flap folded up by means of its linkage on the ring part can be. In addition, the handle bottle on the ring part during the opening process no or only insignificant bending forces exerted on the lid. Thereby a permanent deformation is prevented, so that the container closed several times with the same lid and again can be opened. It also creates the footbridge handle tab protruding downwards a longer lever arm for Open the lid.

To ensure that several lids can be stacked on top of one another to ensure the ribs extend over the Handle tab that they have no hindrance when stacking the lids form.

A major improvement in power transmission from the Handle tab on the lid is achieved in that the Rib a stop for the outer surface of the ring part point. This allows the handle tab to be swiveled upwards until the stop on the outer surface of the ring part comes into contact after a pivoting of about 90 °, d. H. in about horizontal position with regard to the position of use of the Container. If the pull tab is then pulled further, then not only the simple tensile force acts on the lid, but also a tensile force increased by the leverage effect. So that will the removal of the lid is further facilitated.

Because between the sides of the grip tab and the adjacent End faces of the ring part a more or less large Zwi must remain, it is appropriate if the since connections cover the surrounding web. Thereby it is prevented that the cover, for example, by means of a tool could be opened without breaking the predetermined breaking points to disturb.  

In a continuation of the invention, the handle extends flap at least up to the web and comes out with one the upright grip edge, which hides the bridge. There the grip tab is particularly easy to grasp. The Grip edge can advantageously be made from a grip tab radially protruding edge in the width of the Grip tab and a molded downward-facing area consist.

In a further embodiment, the grip tab is over a Thin point attached to the bead ring of the lid, the preferred is designed as a film hinge.

For a particularly good attachment of the lid to the container in the Original condition and possibly again after renewed To reach the top, the handle with the Interlocking web can be positively connected.

For this purpose, an area of the grip edge extends Grip flap over the web and is on the web too facing side with an undercut encompassing the web Mistake. In this case, the cover apron and the Handle part when closing the container for the first time Web can be snapped into place.

In one variant, the web is on the one facing the lid Provide a snap edge on the side in the edge area, behind which grips the grip tab with the lid on. That has the advantage that the lid is not even with a tool can be opened without opening the grip tab and thus to destroy the side connections.

In the following, the invention is intended to be implemented example will be explained in more detail. In the associated drawings shows:

Fig. 1 is a partially broken side view of the container age with the lid engaged;

Figure 2 is an enlarged sectional view of the lid with a molded tab.

Fig. 3 is an enlarged sectional illustration in the region of the tab:

Fig. 4 is an enlarged sectional illustration in the region of the tab at a latching grip tab;

FIG. 5 shows a variant of a latching grip tab with an additional fuse;

Fig. 6 shows the arrangement of two stacked lids;

Fig. 7 is an enlarged sectional view in the region of the handle tab in a variant for a two-sided container; and

Fig. 8 is a partially broken side view of the container age according to Fig. 7 with the cover engaged.

From Fig. 1 and 2, a container 1 made of plastic with a latchable cover 2 can be seen, the lid is provided with a circumferential lid skirt 3 2, which encloses the upper edge of latching in the closed state of the container 1. The latching attachment of the lid 2 to the container 1 is carried out in the usual manner by the upper container edge having an edge bead 4 , behind which a bead ring 5 snaps, which is formed on the inside of the lid skirt 3 of the lid 2 . ( Fig. 3) Furthermore, on the outside of the container wall there is a circumferential web 7 , against which the lower edge of the cover apron 3 rests, or at least almost touches it. This ensures that the cover 2 cannot be removed after it has snapped into place.

In order to enable the container 1 to be reopened after the container 1 has been closed, the cover apron 3 is interrupted at one point on the circumference and has a grip tab 8 in this area, which is provided with a grip edge 9 and with a thin point 10 the ring part 3 is connected. The thin point 10 is expediently designed as a film hinge. The grip tab 8 can thus be grasped at its grip edge 9 and simply folded up. At the same time, there is the possibility of removing the lid 2 from the container 1 .

As can be seen from FIG. 2, the grip tab 8 is simultaneously designed as a tamper-evident closure, ie it should be made clear after the first closure of the container 1 that it is still in its original state. To this end, located on either side of the pull tab 8 is a gap 11 between the grip flap 8 and the respective adjacent portion of the lid skirt 3, which in each case a narrow connection bridges 12 is equal to the hand grip 9 by. These connections 12 are designed as predetermined breaking points and must be destroyed when the container 1 is opened for the first time. This immediately shows whether the container 1 is still in its original condition.

In order to prevent the lid 2 from being opened by means of a tool without destroying the predetermined breaking points, the connections 12 simultaneously cover the web 7 on the outer container wall 6 .

According to FIG. 3, the grip tab 8 extends to the web 7 , the handle edge 9 , which consists of a radially outwardly projecting edge 13 and a molded-down region 14 , surrounds the web 7 .

According to the invention, the grip tab 8 has increased flexural rigidity in at least one dimension. For this purpose, the handle tab 8 is hen with a plurality of parallel ribs 15 , which extend parallel to the axis of symmetry of the container 1 . These ribs 15 reliably prevent the handle tab 8 from bending when it is raised.

In order to achieve a particularly good power transmission from the handle tab 8 to the lid 2 when the container 1 is to be opened, the ribs 15 have stops 16 for the outer surface of the lid apron 3 . As a result, the grip tab 8 can be pivoted upward until the stop 16 comes to rest on the outer surface of the cover apron 3 after a pivoting of approximately 90 ° ( FIGS. 3, 5) and assumes an approximately horizontal position with regard to the position of use of the container 1 . This creates particularly favorable leverage ratios that make it much easier to remove the cover 2 .

A special embodiment of the grip tab 8 can be seen in FIG. 4. Here, the downward-pointing region 14 of the grip edge 9 is provided with an undercut 17 on its side facing the web 7 . This makes it possible that when the container 1 is closed for the first time, both the cover apron 3 on the bead 4 and the grip tab 8 can be snapped onto the web 7 . As a result, the lid 2 is firmly connected to the container 1 over its entire circumference.

In a further variant ( FIG. 5), the web 7 is additionally provided on its side facing the cover 2 in the edge region with a circumferential locking edge 18 , so that the lower edge of the grip tab 8 can grip behind the locking edge 18 when the cover 2 is attached. For this purpose, the grip tab 8 has a projection 19 which can be snapped behind the locking edge 18 . This variant prevents the cover 2 from being opened by inserting a tool between the web 7 and the cover apron 3 .

From the drawing figures, Fig. 7 and 8 show another form of execution is the arrangement of a latching gripping tab 8 on a two-edge container can be seen. The design of the grip tab 8 corresponds to that of FIG. 5. The web 7 has an additional downward peripheral edge on its outer edge. For latching on the grip tab 8 , the web 7 is on its side facing the lid 2 side in the edge region additionally provided with a recess, the width of which corresponds at least to the dimensions of the grip tab 8 . Within this recess there is a latching edge 18 so that the projection 19 located on the lower edge of the grip bottle 8 can engage behind the latching edge 18 when the cover 2 is in place . This variant, like the variant according to FIG. 5, reliably prevents the cover 2 from being opened by inserting a tool between the web 7 and the ring part 3 of the cover 2 .

It goes without saying that instead of the grip tab 8 described above and its variants, several such grip tabs 8 can also be arranged on the circumference of the cover apron 3 , if this is considered necessary.

This solution creates a container 1 made of plastic with a lid 2 , which is particularly easy to remove and put back on, without a reduction in activity you would have to fear. To open the container 1 for the first time, only the grip tab 8 is to be grasped and removed radially from the container wall 6 , so that the grip bottle 8 can be folded up by means of the thin hinge formed as a film hinge 10 until it abuts the stop 16 . If the pulling is now continued in a direction approximately parallel to the longitudinal axis of the container 1 , the cover 2 is released from it. A particular advantage of the invention can also be seen in the fact that the container 1 can be opened several times and how it can be closed without the fear of an increasing leakage of the container 1 . In addition, it is easily possible to reuse the container 1 and to provide it with a new lid 2 . This allows material to be saved very considerably since only the cover 2 is to be replaced.

In order to be able to store several lids 2 in the form of a stack, the ribs 15 are designed such that they extend over the grip tab 8 in such a way that they do not form an obstacle when stacking. As shown in FIG. 3, the ribs 15 are dimensioned in width and height in such a way that they do not come up against the underside or the downward-pointing region 14 of the grip edge 9 when stacked.
