Description

[0001] The invention relates to a storage container according to the preamble of claim 1.

[0002] Storing thin filter discs often presents significant inconvenience when removing them from the storage container. The discs are frequently stacked in the hundreds and stuck together. Separating a single disc from the stack often proves to be a test of patience, and the use of tools such as pointed tweezers frequently results in damage to the disc's edge, leading to subsequent leaks during filtration.

[0003] Therefore, the object of the present invention is to propose a new storage container which avoids the aforementioned disadvantages.

[0004] This problem is solved by the present invention according to the teaching of the independent claim.

[0005] Advantageous embodiments are the subject of the dependent claims.

[0006] According to the invention, the problem is solved by a storage container with a singulation device for filter discs, wherein the storage container comprises a receiving container for the stacked receiving of the filter discs and a lid with which the receiving container can be closed, and wherein a singulation device is arranged on the lid which, in the closed state of the storage container, makes adhesive contact with the uppermost filter disc of the stack.

[0007] The storage container can be of any design, for example a can or a box. However, all other shapes are conceivable.

[0008] The storage container contains a receiving chamber from which the filter discs can be stacked and retrieved. In other words, the stored filter discs are held in stacks within the receiving chamber.

[0009] Furthermore, the storage container includes a lid with which the receiving container can be closed, among other things to protect the filter discs. The type of closure is essentially arbitrary.

[0010] A singulation device is arranged on the lid. When the storage container is closed, this device makes contact with the uppermost filter disc of the stack.

[0011] In other words, the singulation device touches the uppermost filter disc when closed. Due to the adhesive contact, when the lid is opened and separated from the receiving container, the uppermost filter disc remains detachably connected to the singulation device, which in turn is connected to the lid.

[0012] As a result, opening the lid simultaneously detaches and removes the top filter disc from the stack in the same movement.

[0013] The cause of the filter disc adhering to the singulation device is essentially arbitrary. It could be, for example, adhesion, electrostatics, or adhesive. Other causes of adhesion are also conceivable.

[0014] According to a preferred embodiment, the singulation device is designed to be compressible and / or elastic.

[0015] The cause of the compressibility or elasticity is essentially arbitrary. These properties offer the advantage that the singulation device can perform automatic height adjustment. As filter discs are removed, the height of the filter stack steadily decreases, and the distance to the singulation device increases.

[0016] If the singulation device is designed to be compressible and / or elastic, this automatically creates a height compensation with the stack of filter discs. This also ensures that the bottommost filter disc remains in contact with the singulation device and can be removed.

[0017] According to another preferred embodiment, the singulation device comprises a foamed plastic. In this example, the singulation device is designed, for instance, as a sponge or foam.

[0018] These materials are compressible, elastic and inexpensive, thus offering good height compensation.

[0019] According to another preferred embodiment, the height HVE of the singulation device in the relaxed state is greater than the internal height HIG of the storage container in the closed state between the bottom of the receiving container and the inner surface of the lid to which the singulation device is attached.

[0020] The heights HVE and HIG are considered here in the compression direction of the singulation device.

[0021] These dimensions ensure that the singulation device can touch the bottom of the receiving container and thus always makes contact with the lowest filter disc. This prevents any filter discs from remaining inaccessible in the storage container, which would create a negative impression on the user.

[0022] According to a further preferred embodiment, an adhesive is arranged on the singulation device to form the contact surface for the uppermost filter disc, which can be removed from the contacted filter disc without leaving any residue.

[0023] If the adhesive can be removed from the contacted filter disc without leaving any residue, or if the filter disc can be peeled off the adhesive contact surface of the singulation device without leaving any residue, then the filter disc will not be contaminated and will not become partially impermeable, and its weight will also be changed.

[0024] According to a further preferred embodiment, double-sided adhesive tape is arranged on the singulation device to form the contact surface for the uppermost filter disc. This allows for simple and reliable adhesive contact between the uppermost filter disc and the singulation device.

[0025] According to another preferred embodiment, the two adhesive surfaces of the double-sided adhesive tape have different adhesive forces.

[0026] The different adhesive forces on the side of the double-sided adhesive tape facing the singulation device and on the other side facing the top filter disc further increase the reliability of the singulation process.

[0027] If the double-sided adhesive tape adheres more strongly towards the singulation device than towards the uppermost filter disc, then the adhesive tape can be prevented from detaching from the singulation device, while the filter disc is peeled off from the other, more easily removable side of the adhesive tape.

[0028] Otherwise, there would be a risk that the double-sided adhesive tape would also be peeled off the singulation device along with the filter disc, and the next filter disc would no longer adhere to the singulation device.

[0029] One embodiment of the invention is shown in the figures and is explained below by way of example: The figures show: Fig. 1. A cross-sectional view of a storage container with a singulation device in the closed state, Fig. 2 a cross-sectional view of the storage container made of Fig. 1 in the open state.

[0030] Fig. Figure 1 shows a cross-sectional view of a storage container 1 with a singulation device 2 in the closed state. The storage container 1 has a receiving container 3 in which filter discs 4 are stacked. For example, 200 filter discs can be held.

[0031] The lid 5 can be used to close the collection container 3. The lid 5 can, for example, have a screw cap or be attached to the collection container 3.

[0032] A singulation device 2 is arranged on the lid 5 and firmly connected to it. When the storage container 1 is closed, the singulation device 2 makes contact with the uppermost filter disc 4.

[0033] The singulation device 2 is made of a foam material and is compressible and elastic to achieve the aforementioned advantages.

[0034] The internal height HIG of the storage container 1 extends in the compression direction in the closed state between the bottom 6 of the receiving container 3 and the inner surface 7 of the lid 5.

[0035] This height HIG is less than the height HVE, which is below. Fig. 2 is explained. The foam of the singulation device 2 is therefore compressed in the closed state of the storage container 1 and can reach up to the bottom 6 of the receiving container 3 for the removal of the last filter disc 4.

[0036] Fig. Figure 2 shows a cross-sectional view of storage container 1. Fig. 1 in the open state. The lid 5 is separated from the receiving container 3 and lifted off. The singulation device 2 attached to the lid 5 and the filter disc 4 adhering to it were also removed from the receiving container 3.

[0037] The height HVE of the singulation device 2 in the relaxed state is greater than the height HIG when viewed in the same direction. This ensures that even the lowest filter disc 4 can be removed from the receiving container 3.

[0038] On the other hand, this also ensures good accessibility of the filter disc 4, because when the singulation device 2 is released, it is pushed out of the lid and the edges of the filter disc 4 are easily accessible.

[0039] Double-sided adhesive tape is applied to the singulation device 2, in this case the foam stamp, to ensure good adhesion of the filter disc 4 to the singulation device 2. The double-sided adhesive tape is located on the surface that is pressed against the filter disc 4.

[0040] The two adhesive surfaces of the double-sided adhesive tape exhibit different adhesive forces. As a result, when the filter disc 4 is finally removed from the singulation device 2, i.e., when the filter disc 4 is gripped and detached from the singulation device 2, the adhesive force between the double-sided adhesive tape and the filter disc 4 is weaker than the adhesive force between the double-sided adhesive tape and the singulation device 2.

[0041] This prevents the double-sided adhesive tape from detaching from the singulation device 2 and facilitates the detachment of only the filter disc 4 from the double-sided adhesive tape.
