Description

The invention relates to a packaging unit with a container and a lid for the container, wherein the container has a container flange at the edge of the container opening with latching region and wherein the lid has a container flange cross-cover flange with latchable in the latching locking rib.

The document EP 2 392 521 A1 discloses a container or bucket together with the lid, which together form a packaging unit. In the known bucket, for example, a color, a rubbing compound, a liquid or another substance can be stored as a filling. In order to prevent spoilage or dehydration of the contents in the bucket, it must be ensured when the lid is closed that neither contents can escape to the outside nor air can penetrate into the bucket, which is why the known packaging unit has sealing surfaces between the bucket and the lid.

If the contents have been removed from the bucket, then the question arises regularly, what should happen to the empty packaging unit. If it is a bucket of paint that has dried on the inner wall, then the entire packaging unit is either polluting the environment or disposed of expensive or lavishly cleaned in order to fill the bucket with lid again with color. When cleaning solvents are used, which also pollute the environment and the time required for cleaning makes the cleaning process usually so expensive that the packaging unit is disposed of. If the packaging unit is used in the food sector, for example for 10 liters of yogurt, then even slight residues of old contents can make the entire new contents unsalcible and possibly even lead to significant costs if it comes to health consequences due to the consumption of spoiled yoghurt.

In the known packaging unit has thus proved to be a disadvantage that a reusability of the packaging unit after the initial filling and emptying is practically not given. The invention has for its object to provide a packaging unit in which an easy to carry out and inexpensive reusability is given. According to the invention, this object is achieved in that in the closed state of the packaging unit between container and Lid an attachment is provided, which has a container flange over the first attachment flange with latching into the latching portion of the container flange locking rib and a circumferential second attachment flange with latching portion for the locking rib of the lid.

This provides the advantage that the attachable to the container essay can be used to protect the container from contamination. For example, a plastic or textile bag could be fastened fixedly on the attachment, the bag covering the inner wall and the bottom of the container as a result of the attachment of the attachment, thus creating a clean surface for refilling. It is also advantageous that a gas-tight packaging unit has been created. It is particularly advantageous that the use of a bag made of an aroma-tight film sensitive goods can be made longer shelf life.

It is advantageous to provide removable holding means for holding the bag in the essay, as this is the packaging unit together with the essay practically any number of times used. Each time after emptying the contents from the packaging unit, only the holding means must be released before refilling the packaging unit, the old bag exchanged for a new bag and the holding means are re-attached to the attachment. It is particularly advantageous to use a Stülpring in the form of a thick rubber ring as a holding means which is clamped in a recess of the essay together with the edge of the bag. This embodiment of the holding means is particularly simple and inexpensive to implement. Alternatively, with the rubber ring of the bag from a PP or PE profile bag can be connected to the attachment.

It is known in a bucket for paint on the edge of the container to provide a recess in which a closure part of the lid is included. In order to open the originally sealed bucket for the first time, the closure part has to be bent out of the recess of the bucket and broken down from the lid. This gives the buyer of a bucket for paints the certainty that the bucket will never open after the production and filling of the paint in the bucket and the color is intact.

To be particularly advantageous has been found the essay, the lid and the container in such a way that even with located on the container essay the originality of the contents is guaranteed. Chemicals such as adhesives can pass through Oxygen contact to lose quality, which can be advantageously protected by the gas-tight film of the bag. The bucket ensures the mechanical protection of the bag and is reusable. This and further advantageous embodiments of the packaging unit according to the invention will be discussed in more detail below with reference to the figures.

FIG. 1 shows a sectional view of a part of a packaging unit 1 according to the EP 2 392 521 A1 , which is formed by a lid 2 and a container 3 or bucket and is contained in the filling F. The contents F contained in the container 3 are in the FIG. 1 not shown in detail, wherein the container 3 can be used as packaging unit 1 for example colors - such as dispersion - or rubbing plaster for plastering house facades, but also in the food sector for example, large amounts of yogurt. In the container 3 but also any other liquid, viscous, powdery or solid materials can be packed as a product for transport and storage.

The container 3 has a peripheral edge flange 4 pointing outwards at the upper edge of the container 3 with a latching region 5. The latching region 5 is formed by an outer circumferential groove 6 on the edge flange 4, in which a locking rib 7 of a cover flange 8 of the lid 2 can be locked in order to close the container 3 with the lid 2. Both the locking flange 4 and the cover flange 8 run around the entire container 3 or cover 2, whereby the cover 2 is engaged on the entire circumference. By this latching connection, the lid 2 is fixed to the container 3 and can only be deducted from the container 2 by means of a gripping bottle provided on the lid 2, with the application of a certain opening force. The lid 2 has support rings 9 and a lid nose 10 in order to ensure a reliable seal of a sealing surface 11 between the lid 2 and container 3.

In order now to enable the packaging unit 1 to be used again for filling with new filling material F after the old filling material has been removed, an attachment 12 can be latched onto the edge of the container 3. In FIG. 2 is another embodiment of a container 3 is shown with a cover 2, wherein between the container 3 and cover 2 in the closed state of the packaging unit 1 of the attachment 12 is provided.

The attachment 12 has a container flange 4 cross-over the first attachment flange 13 in the latching region 5 of the container flange 4 latching locking rib 14. By means of this first attachment flange 13, the attachment 12 can be snapped into the container flange 4 instead of the cover 2 and thus placed and fastened on the container 3. The attachment 12 further has a peripheral second attachment flange 15 with a latching region 16, in which the locking rib 7 of the lid 2 can be engaged. As a result, the advantage is obtained that the article 12 between the container 3 and the cover 2 can be engaged. The sealing surface 11 between the container 3 and the attachment 12 and a sealing surface 17 between the attachment 12 and the cover 2 ensure the tightness of the packaging unit 1 according to FIG. 2 ,

The attachment 12 now has a circumferential recess 18 in the second attachment flange 15, which forms holding means 19 with a clip-ring 19 which can be clamped in the recess 18. With the Stülpring 19, the edge region of a plastic bag 20 can be clamped in the article 12. This ensures that the attachment 12 can be used to attach the plastic bag 20. The plastic bag 20 is selected in size so that it is large enough to accommodate the entire volume of the container 3. In order to prevent the plastic bag 20 tears when filling with filling material, it has proven to be advantageous rather larger plastic bags with a filling volume greater than that of the container 3 to choose, resulting in easier wrinkling on the Container inner wall can lead, but is not disturbing.

By providing the attachment 12 with the plastic bag 20, the advantage is obtained that the container 3 and optionally also the cover 2 can be reused as often as desired. In particular, in the food industry, must be worked and stored as sterile as possible, a clean storage in the packaging unit 1 can be ensured by the use of each new plastic bag 20.

In the circumferential recess 18 for the Stülpring 19 a further recess 21 for excess material of the trapped plastic bag 20 is provided. In this way it is achieved that the hooded ring can be pressed to the bottom of the recess 18, whereby a particularly reliable and firm connection of the attachment 12 is given to the plastic bag 20.

FIG. 3 shows a part of the original sealed packaging unit 1, in which a closure part 22 of the lid 2 is provided in a recess 23 of the attachment 12. The user can drive with three fingers in arcuate openings and bend the closure member 22 upwards, as in FIG. 4 is shown above. The closure member 22 can then be completely broken off the cover 2, after which the lid can be removed from the attachment 12 for opening the container 3. The user of the packaging unit 1 recognizes whether the closure part 22 has already broken open or not, whether the lid has already been removed once after filling with filling material.

In order to prevent that although the lid 2 is secured with the attachment 2 by the closure member 22, but the attachment 2 can be removed from the container 3 at any time, the packaging unit 1 has a lifting part 24 which can be folded out of the attachment 12. The lifting part 24 is in the FIG. 4 Center in the folded state in the recess 23 of the attachment 12 to see in which the lifting part 24 prevents the removal of the attachment 12 from the container 3 mechanically by a locking lug. To remove the attachment 12, the user can fold out the lifting part 24 from the recess 23, as shown in FIG FIG. 4 shown below. In this folded-out state of the lifting part 24, the locking lug of the lifting part no longer engages in the container 3, which is why the attachment 12 can be removed from the container 3 for replacing the attachment 12. As a result, the advantage is obtained that the originality of the filling material F can be guaranteed in the packaging unit 1 with attachment 12.

FIG. 5 shows the container 3 with attachment 12 and closed lid 2 according to FIG. 2 in a side view and a sectional view. Due to the conical design of the container wall of the container 3, a plurality of packaging units 1 can be stacked one above the other and transported, for example, on a truck, with mechanical loads acting on the packaging unit. Both packaging units 1 with and without attachment 12 can be stacked on top of one another since the provision of attachment 12 advantageously does not change the dimensions of the container bottom or lid 2, which are relevant for stacking.

The refilling of the packaging unit 1 is particularly simple by removing the Stülprings 19 from the recess 18, replacing the plastic bag 20 by a new and pinching the edge of the new plastic bag 20 with the Stülpring 19 in the recess 18 is possible. As a result, the packaging unit 1 can be used virtually any number of times for transporting and storing product F.

It may be mentioned that the packaging unit could of course have a different shape such as round or square. Also any sizes can be realized.
