Definitions
- the present invention relates to the preparation of an infusion, and in particular, the preparation of an infusion from a porous sachet or perforated capsule.
- the present invention relates more particularly to a device for preparing an infusion, configured to ensure the holding and sliding of a connecting wire of an infusion bag or a perforated capsule.
- the present invention also relates to an infusion bag structure containing or intended to contain a product to be infused.
- Many drinks are prepared by immersing an infusion product in a liquid such as hot water for a period of time.
- the product to be infused can be placed in a porous reservoir, such as a porous bag or a perforated capsule often called a “tea ball”.
- Immersing the sachet or capsule in the liquid allows the soluble elements of the product to be infused contained in the sachet or capsule to spread in the liquid, which produces the infusion.
- the longer the product to be infused is kept in the liquid the stronger the infusion.
- the porous sachet is usually attached to the end of a wire, the opposite end of which is attached to a label.
- the sachet can be dipped into and removed from the liquid at any time without having to hold the sachet or put fingers in the liquid, or without having to use an additional instrument such as a spoon.
- EP 3 586 691 in the name of the applicant proposes a solution making it possible to simplify the steps of removing and draining an infusion bag or a perforated capsule, and also making it possible to press a bag of infusion. More particularly and as illustrated in Figure 1, EP 3 586 691 discloses a device for preparing an infusion comprising a cover 1 configured to be placed on the edge of an opening of a container for the preparation of an infusion.

- the cover 1 also includes a locking member 7 cooperating with the wire 3 to lock the bag 4 in different adjustable positions, including after pressing the bag and without having to remove the cover from the container.
- Such a bag structure is also not suitable for producing a reusable bag due to the presence of the thread in the tea receiving volume. It might therefore be desirable to provide an infusion sachet structure more suited to pressing than conventional sachets. It could also be desired to provide a device for preparing an infusion allowing anyone who does not have the cover in Figure 1 to benefit from the draining and optionally bag pressing function that such a cover offers. It could in particular be desired to provide a device for preparing an infusion with a small footprint, which is transportable and can for example be used during a trip. It might also be desirable to provide a device for preparing an infusion which can be produced simply and at lower cost.

- Figure 2 is a bottom view of a device 10 for preparing an infusion according to the invention, configured to ensure the holding and sliding of a connecting wire 3 of a bag 4 containing a product to be infused.
- the device 10 comprises a body 11 of generally longitudinal shape which comprises, along a longitudinal axis LL' and going from one end of the device to the other, a handle 12, a first bearing surface 13, a intermediate region 14 and a second support surface 15.
- the support surfaces 13, 15 are designed to come to rest on the edge of a container.
- the region intermediate 14 comprises a pressing wall 140 comprising an opening 16 for the passage of the connecting wire 3 and against which the bag 4 can be pressed by pulling on the connecting wire 3 after having passed the connecting wire through the opening 16
- the pressing wall 140 is oriented in a horizontal plane corresponding here to the plane of Figure 2, which includes the longitudinal axis LL' and a transverse axis TT' perpendicular to the longitudinal axis LL'. This horizontal plane is defined as being a plane parallel, or substantially parallel within a few degrees, to the surface of the liquid in which an infusion must be prepared.
- the opening 16 is here in the form of a slot oriented along the longitudinal axis LL', to allow the passage of a label 5 fixed to the end of the connecting wire 3.
- the lower face of the pressing wall 140 is flat, but could also be concave in shape adapted to the shape of a sachet.
- the first bearing surface 13 and the second bearing surface 15 are flat, but could be of a shape suitable for a particular shape of a container rim.
- the underside of the handle 12 is flat but any raised shape could also be retained, in particular for decorative reasons.
- the upper faces of the handle 12, of the first support surface 13, of the intermediate region 14 and of the second support surface 15, not visible in Figure 2, can also be flat or have any relief shape that can be desired, particularly for decorative reasons.
- the body 11 of the device 10 can also comprise connection regions 17a, 17b, 17c extending between, respectively, the handle 12 and the first support surface 13, the first surface of support 13 and the intermediate region 14, the intermediate region 14 and the second support surface 15, which can be of any width or shape.
- the device 10 can also include extensions 17d, 17e extending respectively beyond the second support surface 15 and the handle 12.
- Figure 3 shows an example of use of the device 10 in association with a container 8 containing a liquid 9.
- the body 11 of the device 10 seen in profile here has flat upper and lower faces, including in its region forming the handle 12
- the surfaces 13, 15 bear on the edge of the container 8 and more particularly on two opposite sections of the edge of the container.
- the device 10 is arranged in the horizontal plane as defined above and the pressing wall 140 extends parallel to the surface of the liquid or substantially parallel if the container is placed on a support which is not horizontal or has an edge irregular in shape.
- the connecting wire 3 passes through the slot 16 and the bag 4 is immersed in the liquid 9. At its other end, the wire 3 is wound around the handle 12, to lock the bag 4 in the position shown.
- Figure 5 is a bottom view of an embodiment 10a of the particularly simple and inexpensive device, in which the body 1 has the shape of a flat stick in which the orifice 16 has been made, here in the shape longitudinal slot.
- the different regions of the stick l ia fulfill the aforementioned functions, respectively the functions of handle 12, first support surface 13, intermediate region 14 and second support surface 15.
- the pressing wall 140 is the part of the stick l ia which extends around slot 16.
- Figure 6 is a bottom view of an embodiment 10b of the device which differs from embodiment 10a in that the body 11b, still in the shape of a flat stick, has two notches 180, 181 made in the handle 12 , facilitating the winding and blocking of the connecting wire 3 around the handle 12.
- the notches are replaced by a peripheral groove or groove made in the handle 12.
- Figure 7 is a bottom view of an embodiment 10c of the device which differs from embodiment 10b in that the body 11c, still in the shape of a flat stick, has a pressing wall 140c of greater width and therefore of greater surface area than the pressing wall of the device 10b, obtained here by an enlargement of the intermediate region 14 of the stick along the transverse axis TT'.
- Figure 8 is a bottom view of an embodiment lOd of the device which differs from embodiment 10c in that the body l ld, still in the shape of a flat rod, has an opening taking the form of a slot longitudinal open 16d which extends from one end of the device opposite the handle 12, here the end of the support surface 15, to the pressing wall 140c.
- a slot longitudinal open 16d which extends from one end of the device opposite the handle 12, here the end of the support surface 15, to the pressing wall 140c.
- Such an open slot 16d facilitates the introduction of the connecting wire 3 into the slot passing through the end of the slot without having to pass the label 5 of the bag through the slot.
- This embodiment also makes it possible to use the lOd device with a perforated capsule like a tea ball, connected to a chain at the end of which there is a fixing or gripping means such as a hook. It then becomes possible to engage the chain in the slot 16d without having to pass the fixing or gripping means through it, and it is then not necessary to increase the width
- Figures 9, 10 are top and bottom views of an embodiment 10e of the device which differs from embodiment lOd in that a wall 19 for retaining the bag, forming a sort of “hood” is assembled on the rear face of the body 1 of the device 10e, at the above the pressing wall 140c.
- the retaining wall 19 connects two edges of the pressing wall 140c and forms therewith a volume 190 for receiving the bag.
- the wall 19 can be assembled by gluing on the body 1 but the assembly can also be produced in a single block, for example by injection of a thermoplastic material or by 3D printing.
- the blocking member formed by the notches 180, 181 is replaced by a blocking member comprising a cylindrical protuberance 182 fixed on the front face of the body 1 le.
- the protuberance 182 comprises, near the body 1, a part 183 of smaller diameter forming an annular groove or groove 184 in which the connecting wire can be wound.
- Figure 11 shows an example of use of the device 10e similar to the example of Figure 3, in association with a container 8 containing a liquid 9.
- the device 10e is horizontal or substantially horizontal, the surfaces 13, 15 being supported on the edge of the container 8.
- the pressing wall 140c is itself horizontal or substantially horizontal.
- the connecting wire 3 passes through the slot 16d, crosses the receiving volume 190 delimited by the wall 19, and the bag 4 is immersed in the liquid 9. At its other end, the wire 3 is wound in the groove 184, to block the bag 4 in the position shown.
- the user can then unlock the wire 3, then pull on the wire until the bag 4 is housed in the receiving volume 190. Additional traction on the wire allows the bag to be placed bag 4 in a pressing situation, the bag resting against the pressing wall 14 and against the wall 19. The user can also choose to leave the bag in a draining situation. Then, the user rewinds the wire 3 in the groove 184, to block the bag in the receiving volume 190.
- the sachet can be placed in the receiving volume 190 before the infusion step.
- the device can be immersed leaving the handle 12 outside the container, the section 13 resting on the edge of the container while the end of the section 15 rests on the bottom of the container.
- the bag 4 is then infused while remaining in the receiving volume 190.
- the device will preferably be made with a material with low thermal conductivity, such as wood or plastic.
- the user has carried out the operations described in relation to Figure 12, then placed the device 10e on a horizontal support, for example a table. Due to the slight inclination of the device 10e, linked to the presence of the wall 19, a small quantity of the liquid 9 resulting from the draining of the bag is collected by the wall 19 and remains in the receiving volume 190.
- the device which has just been described is capable of various other variants, embodiments and applications.
- the pressing wall defined as the region extending around the opening 16, could be substantially vertical, like the partition 5 of the cover shown in Figure 1. It will however appear clearly to those skilled in the art in the light of the exemplary embodiments described in the above, that the horizontal arrangement of the pressing wall has various advantages and in particular that of making it possible to produce a device with a very simple and inexpensive structure to achieve.
- the infusion preparation device can be made with all types of materials (wood, ceramic, glass, metal, plastic, etc.). As indicated above, it can also be used with a perforated capsule (tea or infusion ball) in which the connecting element, instead of being a thread, is a chain or cord. In this case, the pressing function will not be usable and the device will be used as a means of immersion, liquid removal and draining.
- the length of the body 11, 1 la to l ie can be of the order of a few centimeters to around ten or even twenty centimeters depending on the size of the container with which the use of the device 10 is envisaged.
- the receiving volume 190 can be adapted to receive an infusion bag or a perforated capsule.
- the blocking member 180, 181, 182, 183 which can be adapted to block a chain in different positions.
- the device which has just been described is compact and can be placed in a cover or case to be taken along during a trip. It constitutes an alternative or a complement to the lid described by EP 3 586 691. It can be presented to tea lovers as a “tea spoon” and, in certain embodiments, be made of a noble material, metallic or not, or on the contrary be made at very low cost in a plastic material.
- Figure 15A and Figure 15B show in a front view and a rear view an embodiment of an infusion bag 20a according to the invention, capable of being pressed against the pressing wall 140, 140c of the device which has just been be described, or against the interior partition 5 of a lid of the type shown in Figure 1.
- the bag produced here is intended to be reusable, and must therefore have an opening for introducing or extracting tea or other product to infuse.
- the bag 20a comprises a left side edge 21a, a right side edge 21b, a distal edge 21c and a proximal edge 21d.
- the edges 21a, 21b, 21d are here rectilinear while the distal edge 21c is rounded in shape, here substantially semi-circular.
- the bag is attached to a connecting wire 3 which passes through a groove 30 made in the bag, the groove being closed and forming a channel for guiding the wire.
- the groove 30 extends here along the edge lateral 21a where it forms a first groove section 30(a), along the lateral edge 21b where it forms a second groove section 30(b), and along the distal edge 21c where it forms a third groove section 30 (vs).
- the wire 3 comprises a first branch 3a which enters the groove section 30(a) and a second branch 3b which enters the groove section 30(b).
- the branch 3a after passing through the groove section 30(a), enters the groove section 30(c) extending along the distal edge 21c, until reaching a point 33.
- the branch 3b after passing through the groove section 30(b), enters the groove section 30(c) until reaching point 33.
- Point 33 is for example located in the middle of the groove section 30(c).
- Point 33 is optionally but preferably a point of attachment of each branch 3a, 3b of the wire to the bag, produced by sewing, gluing or welding, making it possible to balance or “symmetrize” the tensile force applied by each branch 3a, 3b on the distal edge of the sachet when the sachet must be squeezed.
- the bag 20a is made here from a front piece 22 and a rear piece 23 in a porous material, which have been assembled together.
- This material can be paper and in particular paper gauze, heat-sealed paper fiber, a fabric such as silk, cotton, nylon or a porous plastic.
- the assembly of the two parts can be done by sewing, gluing, welding, depending on the type of material used.
- the groove 30 is delimited by two assembly lines 31, 32 of the parts 22, 23, produced by sewing, gluing or welding.
- Line 31 includes line sections 31(a), 31(c), 31(b) and line 32 includes line sections 32(a), 32(c), 32(b).
- the line sections 31(a), 32(a) delimit the groove section 30(a), the line sections 31(b), 32(b) delimit the groove section 30(b), and the sections of line 31(c), 32(c) delimit the groove section 30(c).
- Parts 22 and 23 are thus assembled over the entire periphery of the bag with the exception of the proximal edge 21d where they can be moved away from each other to introduce the product to be infused.
- part 23 includes an extension 24 of its surface which is folded over part 22 to form a flap 24 (FIG. 15 A) which prevents the product to be infused from leaving the bag during the infusion phase.
- the flap 24 has an orifice 25a allowing the branch 3a of the connecting wire to pass through the flap 24 to enter the groove section 30(a).
- the flap 24 has an orifice 25b allowing the branch 3b to pass through the flap 24 to enter the groove section 30(b).
- the connecting wire 3 is not cut at the attachment point 33 and the branches 3a, 3b form only one and the same uninterrupted wire.
- the bag 20a has the advantage of offering effective pressing of the product it contains when the wire 3 is pulled in a direction opposite to that of the bag, while the proximal edge 21d of the bag is supported against a surface or pressing wall of the type previously described.
- the branch 3a slides in the groove section 30(a) and in part of the groove section 30(c) and pulls the attachment point 33 towards the proximal edge 21d
- the branch 3b slides in the groove section 30(b) and in part of the groove section 30(c) and also pulls the attachment point 33 towards the proximal edge 21d, causing the bag to be folded and pressed against the partition or pressing wall.
- the flap 24 has a single orifice 25 through which the branches 3a and 3b of the wire 3 pass.
- the orifice 25 is for example arranged at mid-distance from the side edges 21a , 21b, or at the center of the proximal edge 21d.
- the branch 3a of the connecting wire extends under the flap 24 and over substantially half the length of the proximal edge 21d before entering the groove section 30(a).
- the branch 3b of the connecting wire extends under the flap 24 and over substantially half the length of the proximal edge 21d before penetrating into the groove section 30(b).
- the wire 3 enters the groove section 30(a) where it forms the proximal end of the branch 3a, extending to the end of the section throat 30(a) where it is fixed to the parts 22, 23 forming the bag by a fixing point 33a. Then, the wire 3 extends into the groove section 30(c) where it forms a branch 3c connecting the branches 3a, 3b, until reaching the end of the groove section 30(c) where it is fixed to parts 22, 23 by a fixing point 33b. The wire then passes through the groove section 30(b) where it forms the proximal end of the branch 3b then emerges outside the bag.
- branch 3a of the wire is attached to the bag at point 33a and branch 3b is attached to the bag at point 33b.
- the connecting branch 3c is attached at its two ends at points 33a and 33b.
