Description

DEVICE FOR PREPARING BEVERAGES BY INFUSION FOR ISOTHERMAL CONTAINERS AND ISOTHERMAL BOTTLES

The present invention relates to a device for preparing drinks by infusion for insulated pouring pots and insulated bottles with the characteristics of the preamble of claim 1.

Document DE 20 2016 103 314 U1 discloses in a known manner a device for preparing drinks by infusion serving at the same time as a closure element for an insulated pouring pot or an insulated bottle. The plant intended for infusion can be kept dry in a perforated basket separate from the interior space of the insulated pouring pot - from the bottle - while it is filled with hot water. The basket is lowered into the water for infusion just before being savored by the user. After infusion of the plant, the perforated basket is removed and completely separated, as well as its contents from the prepared infused drink; bitter substances, coming from an extended infusion time, cannot be released into the brewed beverage prepared in the interior of the pouring pot or the bottle below. The guide of the perforated basket in a screw-shaped guide makes it possible in particular, with moderate force, to lower the perforated basket via a manipulable element accessible from the outside, however only when a reduced inclination of the screw pitch is chosen. The user must therefore rotate the manipulative element several times in order to be able to lower the perforated basket completely and / or raise it again. Both hands are necessary to perform these rotations. In addition, it is not possible to determine with certainty without removing the device for preparing infused drinks from the pouring pot or the bottle whether the perforated basket is currently lowered or raised or is in an intermediate position.

The objective of the present invention is to provide an improved device for preparing beverages by infusion for insulated pouring pot or insulated bottle allowing rapid movement of the perforated basket between a closed dry position, a closed infusion position, and a position open after infusion. This device also allows an easy visualization of these positions by the user thanks to the development of a unique visual position indicator.

This objective is achieved due to a device for preparing drinks by infusion for insulated pouring pots and insulated bottles, comprising at least:

- a basic element which can be inserted into a neck of the insulated pouring pot or of the insulated bottle and comprising at least one pouring opening which can be closed via a closing unit and extending under the pouring opening into a central tube;

- an infusion member disposed in the central tube so that it can be slid in an axial plane by means of a lowering device and sealed relative to it;

- A perforated basket (30) which is connected to the infusion member, the whole being movable between an infusion position in which it emerges at least with part of its height out of the central tube and a closed position in which the central tube is closed by an impermeable bottom of the perforated basket (30);

characterized in that the lowering device is formed by a manipulable element arranged so as to be able to pivot in the closing unit and a connecting rod-crank system, which connects the manipulable element and the infusion member so as to transform the rotational movement of the manipulable element into a translational movement of the infusion member.

The use of a connecting rod-crank system, which connects the manipulable element and the infusion member together makes it possible to achieve, with a small stroke of the manipulable element at the outer side, a greater stroke at the level from the perforated basket, to take the perforated basket out of the central tube for the infusion process and then bring it back there, so that the perforated basket is housed in a fluid-tight manner in the central tube and that no remaining fluid from leaves of the infused drink do not drip into the interior of the insulated pouring pot or the insulated bottle.

In addition, the connecting rod-crank system with the linked lever elements makes it possible to give a compact form to the lowering device which can easily be brought inside the pot or the bottle, even in the presence of small diameters of the preparation of infused drinks.

An additional advantage is that the flow path allowing the exit of the drink is located entirely next to the central tube while the lowering device and the perforated basket insert are inside. It is advantageous here that the perforated basket insert can be moved independently of the opening position of the closing unit. The brewing process can also be carried out with the pouring opening both open and closed. The closing unit can be arranged in a simple manner, in particular providing for configuring it simply so that it can rotate at a defined angle relative to the basic element, so that with rotation, at least a pouring opening located in the radial device outside the central tube can be released or closed again.

Preferably, it is provided for this purpose that the closure unit has at least one central section in the form of a cylindrical tube and a projecting edge beyond the radial device. The cylindrical central section is inserted into the central cylindrical tube of the base element. It is open at the top, so that parts of the connecting rod-crank system can be guided through the central tube of the base element and the central section to the outside of the brewing device located outside the sealing device. At the same time, the edge covers in a closed position at least one pouring opening and closes it via a sealing ring of the sealing surface.

The connection between the base element and the closure unit can simply be carried out by means of a screw thread, knowing that during screwing for closure, an interposed sealing ring is compressed.

Preferably, a bayonet attachment is made between the cylindrical central section of the closure unit and the central tube of the base element. We thus always obtain defined angular positions for an open position and a locked position.

A particularly preferred embodiment provides that the bayonet attachment is formed by at least two studs disposed at the outside of the central section and at least two guide grooves made at the inside of the central tube, the guide grooves respectively comprising an introduction section oriented parallel or at an acute angle to the central axis and a locking section oriented at an obtuse angle to the central axis. The insertion section allows disassembly while the locking section allows two additional positions thanks to its inclination: a closed position in which the pins are respectively positioned at the end of the locking section of the guide groove and in which the pouring opening is closed, as well as a pouring position in which the closing unit is secured relative to the base element and therefore cannot be detached, but has an axial spacing between the 'closing element and the basic element releasing the opening of payment.

The fixing of the perforated basket with the closing unit can be carried out via snap connections. A screw connection is also possible, this having the advantage that the diameter can be chosen so that the closing unit can be pulled up with the perforated basket up out of the central tube because no lateral projection must be present.

Other advantageous configurations of the device for preparing beverages by infusion according to the invention are described with the aid of the example of embodiment described in the following drawings. The figures show respectively in a perspective view:

The figure 1 illustrates an example of a device for preparing drinks by

infusion 100 seen from above in perspective. This consists of a base element 10 placed on the neck of an insulated bottle and a closure unit 20 inserted in the base element 10 and which can rotate relative thereto. The three possible positions of the closing unit 20 are shown at the interior side of a pouring edge 11. A manipulable element 21 capable of pivoting in the closing unit 20 marks the current angular position. Figure 1 shows the closed position. A pouring space 12 is made between the closing unit 20 and the pouring edge 11. The base element 10 continues downwards in a central cylindrical tube 13.

FIG. 2 also shows an example of a device for preparing drinks by infusion 100 in the closed position of the closure unit 20, that is to say that its angular position relative to the base element 10 has not changed. modified with respect to FIG. 1. The basic element 10 and the closure unit 20 form a sealed assembly, in particular against fluids. Compared to Figure 1, the manipulate element 21 is tilted upwards, a perforated basket 30 being removed from the central tube 13 by means of an internal lowering device.

FIG. 3 shows an example of a device for preparing drinks by infusion 100 in the pouring position of the closing unit 20, that is to say that it has pivoted at an angle of approximately 25 ° in the direction counterclockwise with respect to the position according to Figures 1 and. Compared to Figure 2, the manipulate element 21 is in the lowered position; the perforated basket 30 is tucked up inside the central tube 13. It cannot be distinguished in FIG. 3 that the basic element 10 and the closing unit 20 have slightly deviated from one of the 'other in the axial device, so that at least one pouring opening 15 is opened and the drink can reach the pouring space 12. The drink reaches the pouring space 12 from the inside of an insulated bottle on which the device for preparing drinks by infusion 100 is placed, then is directly drunk beyond the pouring edge 11 by a user or can be poured into a cup by the same path.

In the representation in FIG. 4, the closing unit 20 has pivoted with respect to the basic element 10 by an angle step of approximately 25 ° additional with respect to the position of FIG. 3 and up to to reach the unlocking position. In addition, in FIG. 4, the perforated basket 30 is protruded downwards out of the central tube 13 via the manipulable element 21. To connect by complementarity of shapes the perforated basket 30 in the form of a pot with an infusion member 33 arranged inside the central tube 13, a groove 32 is arranged in the region of the upper edge of the perforated basket 30. The convex part of the groove 32 extends towards the interior of the basket 30. A sealing ring 31 is placed in the region of the impermeable bottom plate of the perforated basket 30, so that the central tube 13 remains fluid-tight when the perforated basket 30 is placed inside the central tube 13.

The device for preparing drinks by infusion 100 of FIG. 4 can be represented in an exploded view showing its main components in the unlocked position as illustrated in FIG. 5.

The closing unit 20 has a central section 23 in the form of a tube and an edge 22 projecting in the radial plane, the central section 23 being able to be inserted into the central tube 13 of the base element 10 and the edge 22 covering the opening 15 in a closed position. Tenons 24 are made projecting from the central section 23. A cavity 26 is provided in the upper part of the closure unit 20 to accommodate the manipulable element 21. The infusion member 33 comes out at the lower side of the central section 23.

Several pouring openings 15 are arranged in an arc around the mouth of the central tube 13. The closing unit 20 can be coupled to the base element 10 via a bayonet attachment 24, 14.1, 14.2 formed between its central section 22 and the central tube 13 of the base element 10. Guide grooves provided for the tenons 24 are produced at the inner side 13.1 of the central tube 13, one of which is visible in FIG. 5. A section d introduction 14.1 extends downwards, parallel to the central axis, from the edge of the central tube 13 and then extends at an angle of more than 90 ° into a locking section 14.2. Two locking positions are arranged inside the locking section 14.2, in particular one in the center for the pouring position and one at the end for the closed position. Preferably, the bayonet attachment is formed by at least two pins 24 disposed at the outside of the central section 23 and at least two guide grooves made at the inside 13.1 of the central tube 13, the guide grooves having respectively an introduction section 14.1 oriented parallel or at an acute angle to the central axis and a locking section 14.2 oriented at an obtuse angle to the central axis.

The arrows in FIG. 5 indicate on the one hand the possible amplitude of the rotational movement of the closure unit 20 relative to the base element 10 and on the other hand the axial movement for assembly and disassembly .

FIG. 6 illustrates the internal structure of a device for preparing drinks by infusion 100 according to the invention in the form of a sectional and perspective view. The same closed position according to Figure 1 is shown.

The central section 23 of the closing unit 20 is inserted into the upper part of the central tube 13. The edge 22 situated at the level of the closing unit 20 rests with a sealing ring 25 on the pouring openings 15. A casing sealing ring 16 is provided in the radial plane outside the pouring openings 15 at the level of the base element 10 for the connection with the neck of an insulated bottle. This housing sealing ring 16 is provided at the level of the base element 10 for sealing the insulated pouring pot or the insulated bottle with respect to the neck and the pouring opening 15 is arranged in the radial plane between the ring d housing 16 and the central tube 13. An annular zone placed between the housing sealing ring 16 and the central tube 13 comprises several pouring openings 15 arranged in an arc and a sealing ring 25 or respectively a surface d the sealing of a pouring opening 15 is arranged (or are arranged) respectively at the level of the lower side of the edge 22.

An infusion member 33 is guided over a large part of its height in the central section 23. A lower part protrudes into the central tube 13 and has at its outer periphery a sealing ring 34 in the axial plane with respect to at the lower edge of the central section 23 and serving as a radial seal, even when the infusion member 33 is lowered in the axial plane. Locking tabs 35 clip under the groove 32 at the perforated basket 30.

A lowering device forming a connecting rod-crank system (41, 42, 43, 44) is produced inside the device for preparing beverages by infusion 100. The manipulable element 21 is extended until it reaches a first element lever 41 disposed at a fixed bearing 42 in the closing element 20. The first lever element 41 forms the crank of the rod-crank system.

is the only fixed point in the chain of transmission. A joint 43 is formed between a rear end of the first lever element 41 and a second lever element 44. The second lever element 44 forms the connecting rod of the connecting rod-crank system. The lever element 44 is in turn connected, via a hinge 45, to the infusion member 33. The second lever element 44 is oriented, in the closed position, at an acute angle relative to the axis central of the device for preparing beverages by infusion 100. The first and second lever elements 41, 44 form, in the closed position shown, an angle of approximately 70 °. We can see in Figure 6 that the rod-crank system requires only a small footprint. The elevation of the closing unit 20 relative to the device for the pouring openings 15 is reduced since the device only comprises the first lever element 41 with the button molded unilaterally to serve as a manipulable element 21. The with the manipulable element 21, the closing unit 20 does not reach the height of the pouring edge 11.

The second lever element 44 has a lateral extension 44.1 with a sealing element 44.2 of hemispherical shape. This presses in the closed position on a ventilation opening 36 in the upper side of the infusion member 33.

The sealing ring 31 located below, at the level of the perforated basket 30, provides sealing by cooperation with the central tube 13. Since the bottom of the perforated basket 30 is waterproof, the device for preparing beverages by infusion 100 is thus already fully sealed downwards, towards the housing of the pouring pot or the insulated bottle. The volume between the impermeable bottom of the perforated basket 30 and the closed upper side of the infusion member 33 is also entirely sealed upwards by the sealing ring 34 and the ventilation opening 36, so that no fluid can be poured out of the perforated basket 30, even when the pouring pot or the bottle must be turned over with the device for preparing drinks by infusion 100.

FIG. 7 illustrates the position of infusion of the device for preparing drinks by infusion 100 with the perforated basket 30 taken out of the central tube 13 by means of the internal lowering device. When the manipulable element 21 is tilted upwards, the first lever element 41 pivots about the axis 42 and with the articulation 43 downwards, the second lever element 44 moves in a position parallel to the central axis and applies a force directed downwards on the infusion member 33 with the perforated basket 30. When the lever element 44 is brought into the parallax position illustrated in FIG. 7, the sealing element 44.2 is lifted further from the ventilation opening 36. Since the perforated walls of the perforated basket 30 are withdrawn from the central tube 13, the air and / or the steam leaving the closing unit 20 can exit from the inside the pouring pot or the insulated bottle passing through the ventilation opening 36.

The perforated basket 30 can be removed in this position from the infusion member 33, see FIG. 8. The device for preparing drinks by infusion 100 thus does not need to be completely disassembled for normal use including filling plants for infusion and subsequent cleaning of the perforated basket.
