Recycling of infusion capsules
View Patent ↗A device for separating infusion capsules comprises a base unit and a plunger, the base unit having a face with an aperture for receiving a body part of the capsule, the plunger comprising a projection sized to fit within the aperture, and a stop to limit how far the plunger can be pressed down onto the base unit, wherein the height of the projection beyond the stop is approximately the same as but no greater than the height of the infusion capsule, thereby to fully invert the capsule. A capsule can be placed, rim side down, on the base unit over the aperture, and the plunger used to urge the capsule down into the aperture. The result is that the capsule inverts, rupturing the foil layer and emptying the coffee or other infusion into the base unit below the aperture. The coffee (etc) and the capsule can then be removed for separate recycling. The length of the plunger substantially completely inverts the capsule when pressed, ejecting as much of the content of the infusion capsule as possible instead of allowing some to be trapped in creases in the capsule material.
1 . A device for separating infusion capsules, comprising a base unit and a plunger,
the base unit being in the form of a hollow cup and having a removable lid, the lid having an aperture for receiving a body part of the capsule;
the plunger comprising a projection sized to fit within the aperture, and a stop to limit how far the plunger can be pressed down onto the base unit, wherein the height of the projection beyond the stop is approximately the same as but no greater than the height of the infusion capsule, thereby to fully invert the capsule.
2 . The device according to claim 1 , in which the face has one or more upstanding ridges surrounding the aperture.
3 . The device according to claim 2 , in which the upstanding ridges are located so as to surround a rim of a standard-sized infusion capsule.
4 . The device according to claim 1 , in which the aperture is circular.
5 . The device according to claim 1 , in which the aperture is sized to receive a body of a standard-sized infusion capsule, but not an exterior rim thereof.
6 . The device according to claim 1 , in which the projection is sized so that, when fully inserted via the aperture, it extends beyond the face by a distance which is not greater than but is a substantial part of the depth of a standard-sized infusion capsule.
7 . The device according to claim 1 , in which the projection has a tip for contacting the infusion capsules which is concave.
8 . The device according to claim 1 , in which the infusion capsule contains ground coffee.
9 . The device according to claim 1 , in which the base unit and the plunger are formed as separable components.
10 . The device according to claim 1 , in which the base unit being in the form of a hollow cup has an open upper face and wherein the removable lid is located over the open upper face.
