Definitions

• the present invention relates to the production of a beverage by passing hot water through a capsule containing a dose of product, eg coffee.
• the capsule is in a position called extraction position.
• the passage is dimensioned so as to guide the capsule easily to its extraction position.
• the capsule insertion devices of the state of the art however have the disadvantage of not ensuring a firm positioning of the capsule during its introduction into the machine.
• the problem that the present invention proposes to solve lies in an improvement in the positioning of the capsule during its introduction into the machine and / or when it is ejected from its extraction position.
• the invention takes advantage of the fact that most capsules have a sidewall with a certain flexibility. It is therefore possible to substantially deform the wall of these capsules without destroying them, and thus to ensure optimal guidance of the capsule in the machine.
• the present invention therefore relates to a device for the insertion and / or ejection of capsules, e.g. ex. coffee machine, comprising a passage through which the capsule is transferred and which is characterized by a section smaller than the section of the capsule.
• Figure 1 shows a top view of a capsule before and after crossing a passage.
• Figure 2 shows a capsule before its transfer through the passage.
• Figure 3 shows a capsule in its position through the passage.
• Figures 4 to 6 show the successive steps of the introduction of a capsule by means of a lever.
• Figures 7 to 9 show the successive steps of introducing a capsule through a passage having a particular arrangement.
• Figures 1 0 to 1 2 show the successive steps of the introduction of a capsule through a passage whose section has an editable contour.
• Figures 1-3 to 15 illustrate a capsule introduction mechanism through a passageway.
• Figures 1 6 to 18 illustrate a variant in which the reduced section passage is disposed between the extraction position and the recovery location of the capsule.
• Housing Figure 1 shows a plate 1 1, 12 (middle figure) in which is disposed a passage 2 whose section is smaller than the section of a capsule 1 in the normal state (left figure). More specifically, the passage 2 has a height substantially identical to the height of a capsule 1 and a reduced width relative to the width of the capsule 1. The zone of reduced width constitutes a deformation zone 3 of the capsule.
• the capsule 1 is deformed (right figure) and its section substantially identical to the section of the passage 2.
• the plate 1 1, 1 2 may be disposed at a higher level, ie upstream of the extraction position, or at a lower level, or downstream of the extraction position.
• a higher level ie upstream of the extraction position
• a lower level or downstream of the extraction position.
• capsules having a certain flexibility ie capsules capable of undergoing elastic or plastic deformation sufficient, can cross the passage without being damaged. If the coefficient of rigidity of the capsule is too high, the capsule can not cross the passage.
• Figures 4 to 5 illustrate a variant of the invention in which the transfer of the capsule 1 through the passage 2 is provided by a lever.
• the deformation zones are in the form of rotating rollers whose axis of rotation lies in the plane defined by the plate 11.
• the deformation zones are in the form of movable plates 6 slidable through guide elements 1 3 disposed towards the edge of the passage 2.
• the movement of the plates 6 can be retained by means of a retaining element 7 fixed to the lever 4.
• FIGS. 1 3 to 1 5 represents a drum January 1 comprising at least one housing intended to temporarily receive a capsule 1. Initially, a new capsule 1 is introduced into the housing 14. The drum 1 1 then performs a rotation, generally 1 80 °, during which the capsule 1 passes through the passage 2.
• FIGS. 16 to 18 show a reduced section disposed in a lower plate 12.
• the passage 1 0 disposed in the upper plate 1 1 has a section substantially identical to the section of the capsule, ie a section devoid of deformation zone.
• the retaining element 7 has an angle so as to release the plates 6 once the lever is fully lowered.
• Other reduced section geometries can be used with the lower plate 12, as p. ex. those of Figures 1 to 9.
