Description

[0001] 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.

[0002] Products are packaged in drum-shaped containers for various applications. In particular, pasty products, such as adhesives and sealants, are typically packaged in a film layer inside metal drums. The products are often removed from these drums by pumping from the top, with a funnel-shaped plate pressurizing the contents so that the product flows up to the pump and can then be conveyed further. Such a container is known from DE3605422.

[0003] However, during this process, a residual amount of product always remains in the container and cannot be pumped out. Depending on the system, this residual amount can range from 5 to 10 liters (in a 200-liter drum).

[0004] It is therefore an object of the present invention to provide a solution that enables better utilization of the product packaged in the container during its use. In particular, the residual quantity that can no longer be conveyed should be kept as low as possible, and the economic efficiency and environmental compatibility of such packaged products should be improved.

[0005] This problem is solved by providing a container with a product packaged therein, comprising: a rigid cylindrical container with a bottom, a side wall and a lid; a flexible lining; a pasty product enclosed by the lining and arranged in the container; wherein the container further comprises an insert arranged on the bottom and under the product enclosed by the lining, having a substantially circular plan smaller than the bottom and positioned substantially centrally on the bottom, such that a gap exists between the insert and the side wall.

[0006] Tests revealed that a significant factor contributing to the limited pumping efficiency is that the pump plate is stopped during its downward movement by the folded feed. Particularly with feeds made of plastic film, there is a risk that the feed, compressed along the side wall of the container, will create an insurmountable obstacle for the pump as it approaches the bottom of the container.

[0007] This finding is now used according to the invention in such a way that the insert creates a space into which the compressed feed can be pressed. The insert raises the effective bottom of the container in a central area (but not at the edges), allowing the pump to squeeze out more material before it is stopped by the compressed feed.

[0008] It has also been shown that this effect can be optimized by adjusting the shape and size of the insole. Such optimized insoles are the subject of the dependent claims.

[0009] By manufacturing this insert as lightly and cost-effectively as possible, the economic and environmental aspects of the invention can be further improved. The use of such inserts is particularly advantageous for high-priced and / or difficult-to-recycle products.

[0010] A key concept of the present invention is to optimize the known process of emptying such containers without requiring any changes to the emptying process or the equipment (e.g., pumps). Instead, according to the invention, a container is provided which additionally includes an insert to optimize the emptying process. Thus, no adjustments or modifications are required on the customer's side, neither to the systems nor to the process.

[0011] In an exemplary embodiment, the insert is dimensioned relative to the container such that the distance is between 2 and 10 cm, preferably between 3 and 9 cm, and particularly preferably between 3 and 8 cm.

[0012] In an exemplary embodiment, the height of the insert is between 1 and 6%, preferably between 1.5 and 4% of the height of the container.

[0013] In an exemplary embodiment, the height of the insert is between 1 and 6 cm, preferably between 1.5 and 4 cm.

[0014] In one exemplary embodiment, the insert has a rectangular, trapezoidal, or polygonal cross-section.

[0015] In one exemplary embodiment, the insert is essentially designed as a truncated cone, or as a truncated cone on a base, or as a cylinder with a rounded top edge.

[0016] In an exemplary embodiment, the insert has at least two spacers which are dimensioned and arranged in such a way that they bridge the gap between the insert and the side wall and thereby predefine a position of the insert on the floor.

[0017] In an exemplary training course, the insert has at least three or at least four spacers.

[0018] 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 gap between the insert and the side wall and thereby predefines a position of the insert on the floor.

[0019] In an exemplary advanced training, the surrounding ring and the inlay are made from a single piece and / or from the same material.

[0020] In an exemplary embodiment, the spacer(s) have a lower height than the insert, in particular a height of less than half that of the insert, and / or in particular the height of the spacer(s) is between 20 and 60% of the height of the insert.

[0021] In one exemplary embodiment, the insert is made of a foamed plastic.

[0022] In one exemplary embodiment, the insert is formed in one piece.

[0023] In an alternative embodiment, the insert is formed in multiple parts, wherein the individual parts are in particular identical.

[0024] 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.

[0025] In an exemplary embodiment, the flexible lining is designed as a film, in particular as an aluminum film or as a polyethylene film.

[0026] In one exemplary embodiment, the container is made of sheet metal.

[0027] In an exemplary embodiment, the container has a volume of 50 to 500 liters, preferably 100 to 300 liters.

[0028] Details and advantages of the invention are described below with reference to exemplary embodiments and schematic drawings.

[0029] They show: Fig. 1a Schematic representation of a container with a product packaged therein according to the prior art; Fig. 1b Schematic representation of a container with a product packaged therein and an insert; Fig. 2a Schematic representation of a container with a product packaged therein during its removal by a pump according to the prior art; Fig. 2b Schematic representation of a container with a product packaged therein and an insert during the removal of the product by a pump; and Figs. 3a to 5b Schematic representations of various inserts;

[0030] In Fig. 1a A container 1 containing a product A is shown according to the prior art. The container 1 has a cylindrical shape and comprises a base 2, a side wall 3, and a lid 4. The product A is also enclosed by a lining 5.

[0031] In Fig. 1b Figure 1 shows a container 1 with a product A packaged inside, but this container 1 also includes an insert 6. This insert 6 is located on the bottom 2 of the container 1 and beneath the product A, which is enclosed by the lining 5. The insert 6 has a diameter 11, which is smaller than the bottom 2 of the container 1. Because the insert 6 is located essentially centrally on the bottom 2, there is a gap 9 around the insert 6 to the side wall 3. The insert 6 also has a height 10.

[0032] In Fig. 2a A container 1 containing a packaged product A is shown in the prior art, depicted during the removal of the product by a pump 7. During removal, the lining 5 on one side of the product A is cut open, and a follower plate 8 of a removal device (not shown in its entirety) presses down on the product A, causing it to be squeezed against gravity towards the pump 7. The pump 7 then conveys the product A further, for example, towards an application robot (not shown).

[0033] As product A is progressively compressed within the casing 5, folds form in the casing 5, each next to the side wall 3. At a certain point, these folds prevent further compression of product A because the folds create too much resistance. This brings the dispensing process to a halt before product A can be completely conveyed (or emptied / used up).

[0034] In Fig. 2b Figure 1 shows a container 1 with product A packaged inside, during its removal by a pump 7. Here, however, container 1 additionally includes an insert 6, which is located at the bottom 2 of the container 1. Due to the central positioning of the insert 6 on the bottom 2, any folding of the feed 5 can now at least partially escape into an area between the insert 2 and the side wall 3. This allows a larger quantity of product A to be dispensed than would be the case without the insert 6, as shown in Figure 1. Fig. 2a depicted.

[0035] In the Fig. 3a bis 5b Various embodiments of inserts 6 are shown, each in a spatial representation and in cross-section.

[0036] In the Fig. 3a und 3b A first exemplary insert 6 is shown. This insert 6 has a substantially rectangular cross-section. Furthermore, this insert 6 is formed in multiple parts, with four identical sections being used to form one insert 6. This insert 6 has no spacer.

[0037] In the Fig. 4a und 4b A second exemplary insert 6 is shown. This insert 6 has a substantially trapezoidal cross-section. Furthermore, this insert 6 is formed in multiple parts, with four identical sections being used to form one insert 6. This insert 6 has four spacers 12, with each section having one spacer 12.

[0038] In the Fig. 5a und 5bA 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 formed as a circumferential ring around the insert 6. Reference symbol list
