Description

The present invention relates to a container with a product packaged therein. In particular, the invention relates to a rigid cylindrical container with a pasty product packaged therein.

Products are packaged in drum-shaped containers for various applications. In particular, pasty products such as adhesives and sealants are typically packaged in a foil layer in tin drums. The products are often removed from these drums by pumping them out from above, with a funnel-shaped plate pressurizing the contents so that the product flows up to the pump and can be pumped on from there.

In this process, however, a residual amount of the product always remains in the container and can no longer be conveyed through the pump. Depending on the system, this residual amount can be in the range of 5 to 10 liters (for a 200 liter drum).

It is therefore an object of the present invention to provide a solution which enables better utilization of the product packed in the container during its use. In particular, a residual amount that can no longer be conveyed should be kept as small as possible, and the economics and environmental compatibility of such packaged products should be improved.

This object is achieved by providing a container with a product packaged therein, comprising: a rigid cylindrical container having a bottom, a side wall and a lid; a flexible lining; a pasty product enclosed by the liner and placed in the container; the container further comprising a liner disposed on the bottom and under the product enclosed in the liner, which liner has a generally circular plan that is smaller than the bottom, and which is disposed substantially centrally on the bottom such that between there is a gap between the insert and the side wall.

Experimentation has shown that a significant component of the limited pumping efficiency is due to the platen of the pump being stopped in its downward movement by the collapsed lining. In particular with liners made of plastic films, there is a risk that the liner compressed along the side wall of the container forms an insurmountable resistance for the pump when it pushes close to the bottom of the container.

This finding is now used according to the invention in such a way that the insert creates a space into which the compressed lining can be pressed. The liner raises the effective bottom of the container in a central area (but not the edge area), allowing the pump to squeeze out more material before being stopped by the crushed liner.

It has also been shown that this effect can be optimized by adjusting the shape and size of the insert. Such optimized insoles are in particular the subject matter of the dependent claims.

By making this insert as light and inexpensive as possible, the economic and environmentally relevant aspects of the invention can be further improved. The use of such inserts is particularly advantageous in the case of high-priced and/or difficult-to-recycle products.

A core idea of the present invention is to optimize the previously known process of emptying such containers without having to make any changes to the emptying process or the equipment (e.g. pumps). Instead, according to the invention, a container is made available which additionally includes an insert in order to optimize the emptying process. This means that no adjustments or changes need to be made by the customer, either to the systems or to the process.

In an exemplary embodiment, the insert is dimensioned relative to the container in such a way that the distance is between 2 and 10 cm, preferably between 3 and 9 cm, particularly preferably between 3 and 8 cm.

In an exemplary embodiment, a height of the insert is between 1 and 6%, preferably between 1.5 and 4% of a height of the container.

In an exemplary embodiment, the height of the insert is between 1 and 6 cm, preferably between 1.5 and 4 cm.

In an exemplary embodiment, the insert has a rectangular or trapezoidal or polygonal cross-section.

In an exemplary embodiment, the insert is formed essentially as a truncated cone, or as a truncated cone on a base, or as a cylinder with a rounded top edge.

In an exemplary embodiment, the insert has at least two spacers which are dimensioned and arranged in such a way that they bridge the distance between the insert and the side wall and thereby predefine a position of the insert on the floor.

In an exemplary development, the insert has at least three or at least four spacers.

In an alternative embodiment, the insert has a circumferential ring as a spacer, which is dimensioned and arranged in such a way that it bridges the distance between the insert and the side wall and thereby predefines a position of the insert on the floor.

In an exemplary development, the circumferential ring and the insert are made in one piece and/or are made of the same material.

In an exemplary embodiment, the spacer(s) has/have a lower height than the insert, in particular a height which is less than half the height of the insert, and/or in particular the height of the spacers is between 20 and 60% of the height of the insert.

In an exemplary embodiment, the insert is formed from a foamed plastic.

In an exemplary embodiment, the insert is formed in one piece.

In an alternative embodiment, the insert is designed in several parts, with the individual sections being designed in particular identically.

In an exemplary embodiment, the product is a one-component adhesive or sealant, in particular a polyurethane-based, silane-terminated polymer-based, epoxy-based or silicone-based composition.

In an exemplary embodiment, the flexible lining is designed as a foil, in particular as an aluminum foil or as a polyethylene foil.

In an exemplary embodiment, the container is formed from sheet metal.

In an exemplary embodiment, the container has a volume of 50 to 500 l, preferably 100 to 300 l.

Details and advantages of the invention are described below using exemplary embodiments and with reference to schematic drawings.

In Fig. 1a 1 shows a container 1 with a product A packaged therein according to the prior art. The container 1 is cylindrical in shape and comprises a bottom 2, a side wall 3, and a lid 4. The product A is also enclosed by a liner 5.

In Figure 2b Again, a container 1 is shown with a product A packaged therein, but this container 1 additionally comprises an insert 6. This insert 6 is placed on the bottom 2 of the container 1 and under the product A enclosed by the liner 5. The insert 6 has a diameter 11, which is smaller than the base 2 of the container 1. Because the insert 6 is arranged essentially in the middle on the base 2, there is a distance 9 around the insert 6 from the side wall 3.
The insert 6 also has a height of 10.

In Figure 2a 1 shows a container 1 with a product A packaged therein being removed by a pump 7 according to the prior art. During removal, the lining 5 is cut open on an upper side of the product A, and a follower plate 8 of a removal device (not shown as a whole) now presses on the product A, so that the product A is squeezed towards the pump 7 against the force of gravity. The pump 7 then conveys the product A further, for example in the direction of an application robot (not shown).

The progressive compression of the product A in the lining 5 causes the lining 5 to fold, in each case next to the side wall 3. These folds in the lining 5 prevent the product A from being further compressed from a certain point, because further compression creates too much resistance causes the folds. As a result, the removal process comes to a standstill before the product A can be completely conveyed (or emptied, used up).

In Figure 2b A container 1 with a product A packaged therein is again shown as it is being removed by a pump 7 . Here, however, the container 1 additionally includes an insert 6 which is arranged on the bottom 2 of the container 1 . By arranging the insert 6 in the middle on the bottom 2 , a fold of the lining 5 can escape at least partially into an area between the insert 2 and the side wall 3 . As a result, more product A can be conveyed overall than is the case without the insert 6, as in Figure 2a shown.

In the Figures 3a to 5b various exemplary embodiments of inserts 6 are shown, each in a spatial representation and in cross section.

In the Figures 3a and 3b a first exemplary insert 6 is shown. This insert 6 has a substantially rectangular cross-section. Furthermore, this insert 6 is designed in several pieces, with four identical sections being used to form an insert 6 . This insert 6 has no spacer.

In the Figures 4a and 4b a second exemplary insert 6 is shown. This insert 6 has a substantially trapezoidal cross section. Furthermore, this insert 6 is designed in several pieces, with four identical sections being used to form an insert 6 . This insert 6 has four spacers 12, each section having a spacer 12.

In the Figures 5a and 5b a third exemplary insert 6 is shown. This insert 6 has a substantially rectangular cross-section. Furthermore, this insert 6 is formed in one piece. This insert 6 has a spacer 12, which is designed as a circumferential ring around the insert 6 around.
