DISPENSING OF A SUBSTANCE

摘要

The invention proposes to dispense a substance from a container filled with a single portion of a substance. The container comprises a preformed deformable body defining a filling cavity which body has an opening and an integral planar circumferential rim surrounding said opening. The opening is closed by a cover sheet which is sealed to the circumferential rim by a circumferential sealing seam. The circumferential rim has a dispensing part which is covered by the cover sheet. A dispensing passage is formed between the dispensing part and the cover sheet. At the location of the dispensing passage is provided a weakened sealing seam portion, such that upon pressurizing the content of the container, the weakened sealing seam portion breaks and substance flows out of the container through the dispensing passage. The dispensing part is flat and the dispensing passage for the substance is defined by the cover sheet sealed to the flat dispensing part by at least two outwardly directed sealing seams. The outwardly directed sealing seams extend at a distance from one another from the circumferential sealing seam to the edge of the dispensing part.

主权项

1. A combination of a container filled with a substance and a dispenser including a holder for receiving and holding the container,
said container comprising a deformable body defining a filling cavity, the container body defining said filling cavity being preformed and having an opening and an integral planar circumferential rim surrounding said opening, which opening is closed by a cover sheet which is sealed to the circumferential rim by a circumferential sealing seam, the circumferential rim having a dispensing part which is covered by the cover sheet, wherein a dispensing passage is formed between the dispensing part and the cover sheet, and wherein the sealing seam at the location of the dispensing passage has a predetermined zone where the sealing seam breaks upon pressurizing the content of the container and the substance flows out of the filling cavity through the dispensing passage, the holder of the dispenser having at least one container positioning bore, and the circumferential rim of the container being provided with at least one corresponding positioning protrusion, wherein the at least one positioning protrusion of the container fits within said at least one positioning bore of the holder.
