Description

  • The invention relates to a tea preparation attachment for Isolierkannen and vacuum flasks with the features of the preamble of claim 1.
  • From the DE 20 2016 103 314 U1 is a tea preparation attachment known, which also serves as a closure element for a jug or vacuum flask. The dry tea can be stored in a tea strainer separated from the interior of the jug or bottle filled with hot water, which is lowered into the water just before drinking. After brewing the tea strainer is withdrawn and is completely separated with its content of the prepared tea beverage; Bitter substances can thus not get into the prepared tea in the underlying interior of the pot or bottle. Although the guide of the tea strainer in a helical guide allows, with little effort, a lowering of the tea strainer via an externally accessible control element, but only if a small pitch of the spindle is selected. Therefore, the operator must perform several revolutions of the control element to completely lower the tea strainer or to be able to retract. For turning he needs both hands. In addition, without removing the tea making attachment from the jug or bottle, he can not clearly determine whether the tea strainer has just been lowered or retracted, or is in an intermediate position
  • The object of the present invention is thus to provide an improved tea preparation attachment for a jug or bottle, with the use of a simple tea preparation is possible in mobile use, in particular, a rapid displacement of the tea strainer between a closed position and a brewing position and a unique position identification be possible should.
  • This object is achieved by a tea preparation attachment having the features of claim 1.
  • The use of an at least two-part crank mechanism, which connects the control element and the Teesiebaufnahmeelement with one another, with a small stroke of the control element on the outside to achieve a larger stroke on tea strainer to push out the tea strainer for the brewing process from the central tube and then withdraw back into it so that the tea strainer is liquid-tightly received in the central tube and dripping no residual liquid from the infused tea leaves into the interior of the jug or vacuum flask.
  • In addition, the crank mechanism allows with the linked lever elements a slim design of the lowering, which is well to accommodate even in small diameters of the tea preparation attachment in the interior.
  • Another advantage is that the flow path for pouring liquid is passed completely past the central tube with the lowering device and the tea strainer insert therein. It is advantageous that the tea strainer can be moved independently of the open position of the closure unit. The brewing process can thus be carried out both with open as well as with closed pouring. Thereby, the closure unit can be easily formed, wherein it is provided in particular to make it easy to rotate over a certain angle relative to the base element, so that with the rotation at least one pouring opening located radially outside the central tube is released or closed again.
  • Preferably, it is provided that the closure unit has at least one cylindrical tube-shaped central portion and a brim projecting radially above it, that is, it is mushroom-shaped. The cylindrical central section is inserted into the likewise cylindrical central tube of the base element. It is open at the top, so that parts of the crank gear can be guided through the central tube of the base member and the central portion to the outside of the sealing level outside of the tea preparation attachment. At the same time the brim covers in a closed position, the at least one outlet opening and closes it via a sealing ring of a sealing surface.
  • The connection between the base element and the closure unit can be easily achieved via a screw thread, wherein when screwing an intermediate sealing element is compressed.
  • However, a bayonet closure is preferably formed between the cylindrical central section of the closure unit and the central tube of the base element. As a result, always defined angular positions for an opening and a locking position are given.
  • A particularly preferred embodiment provides that the bayonet closure is formed by at least two pins arranged on the outer side of the central section and at least two guide grooves formed on the inner side of the central tube, wherein the guide grooves each have an insertion section aligned parallel or at an acute angle to the central axis and an insertion section an obtuse angle to the central axis having aligned locking portion. The insertion portion allows disassembly, while the locking portion allows two additional positions due to its inclination: a closed position in which the pins are respectively positioned at the end of the locking portion of the guide groove and in which the pouring is closed, and a drinking position in which the closure unit opposite the base element is secured, so it can not fall out, but with such an axial distance between closure element and base element is that the pouring opening is released.
  • The attachment of the tea strainer with the closure unit can be done via snap-in connections. Also possible is a screw, which has the advantage that the diameter can be chosen so that the closure unit can be pulled out with the tea strainer upwards from the central tube, because no lateral projections must be present.
  • Further advantageous embodiments of the tea preparation attachment according to the invention will be described with reference to the embodiment shown in the following drawings. The figures each show in a perspective view:
    • 1 a tea preparation attachment in the closed position from the outside;
    • 2 the tea preparation attachment in brewing position with extended tea strainer;
    • 3 the tea preparation attachment in the drinking position;
    • 4 the tea preparation attachment in unlocked position before disassembly;
    • 5 the dismantled tea preparation attachment;
    • 6 the tea preparation attachment in closed position in section;
    • 7 the tea preparation attachment with extended tea strainer in the section; and
    • 8th the tea preparation attachment with removed tea strainer on average.
  • 1 shows a tea preparation attachment 100 from diagonally above. This consists essentially of a base element 10 , which can be placed on the neck of a vacuum flask, and a closure element 20 that is in the base element 10 is used and which is rotatable relative to this. On the inside of a pouring edge 11 the three possible positions are marked. One in the closure element 20 pivotally mounted control 21 marks the current angular position. In 1 this is the shutter position. Between the locking unit 20 and the pouring edge 11 is a spout room 12 educated. Downwards, the base element sits down 10 in a cylindrical central tube 13 continued.
  • In 2 is the tea preparation tower 100 also in the closed position of the closure unit 20 shown, that is, its angular position relative to the base element 10 has faced 1 not changed. Thus, the basic element 10 and the locking unit 20 sealed against each other in a liquid-tight manner. Across from 1 became the operating element 21 pulled upwards, whereby by means of an internal lowering a tea strainer 30 from the central tube 13 has been pushed out.
  • In 3 is the tea preparation tower 100 in the drinking position of the closure unit 20 pictured, that is, he was compared to the position after the 1 . 2 turned by an angle of about 25 ° counterclockwise. The operating element 21 is in the lowered starting position; hence the tea strainer is inside the central tube 13 pulled up. Not recognizable is that with the twisting the base element 10 and the locking unit 20 were slightly axially away from each other, so that at least one pouring opening is open and the drink from the inside of a vacuum flask, on which the tea preparation attachment 100 is placed in the outlet room 12 can reach and either directly over the Ausgießerrand 11 drunk or can be poured over this into a cup.
  • When displayed in 4 became the closure unit 20 compared to 3 by a further angular step of about 25 ° relative to the base element 10 turned to the unlocked position. It was also about the control 21 the tea strainer 30 from the central tube 13 pushed so that it could be pulled down. To the cup-shaped tea strainer 30 with one inside the central tube 13 arranged to connect Teesiebaufnahmeelement positively, is in the range of the upper edge of the tea strainer 30 a groove 32 imprinted. In the area of the bottom plate of the tea strainer 30 is a sealing ring 31 attached so that the central tube 13 with the feeding of the tea strainer liquid-tight with respect to the central tube 13 is sealed.
  • From the unlocked position according to 4 out the tea preparation tower can 100 be broken down into its main components, as in 5 shown.
  • The closure unit 20 has a tubular central section 23 and a radial overlying brim 22 , Outside at the central section 23 are radial pins 24 educated. In the upper part of the locking unit 20 is a recess 26 provided to the operating element 21 take. At the bottom of the central section 23 protrudes the Teesiebaufnahmeelement 33 out.
  • Around the mouth of the central tube 13 around are several arcuate pouring openings 15 arranged. On the inner wall 13.1 of the central tube 13 are guide grooves for the pins 24 trained, of which in 5 one is visible. From the top of the central tube 13 from an insertion section extends 14.1 down to the central axis and then goes at an angle of more than 90 ° in a locking section 14.2 above. Inside the locking section 14.2 two locking positions are formed, namely one in the middle for the drinking position and one at the end for the closed position.
  • The block arrows in 5 on the one hand mark the possible angular range over which the locking unit 20 opposite the base element 10 is rotatable, and on the other hand, the axial movement for disassembly and assembly.
  • 6 shows the internal structure of a tea preparation attachment according to the invention 100 in the form of a perspective sectional view. Shown is the closed position according to 1 ,
  • The central section 23 the locking unit 20 is in the upper part of the central tube 13 used. The brim 22 on the closure element 20 lies with a sealing ring 25 on the pouring openings 15 on. Radially outside the pouring openings 15 are at the base element 10 a sealing ring 16 and a threaded ring for connection to the neck of an insulating bottle provided.
  • A tea strainer pickup element 33 is with much of its height in the central section 23 guided. A lower part protrudes into the central tube 13 and has a sealing ring on the outer circumference 34 axially against the lower edge of the central portion 23 seals and which causes the radial seal, even if the Teesiebaufnahmeelement 33 is lowered axially. locking tongues 35 grab under the groove 32 at the tea strainer 30 ,
  • Inside the tea preparation tower 100 a lowering device is designed in the form of a two-part crank mechanism. The operating element 21 extends to a first lever element 41 on a pivot bearing 42 in the closure element 20 is stored. The pivot bearing 42 is the only benchmark of the transmission chain. Between a rear end of the first lever element 41 and a second lever element 44 is a joint 43 educated. The lever element 44 in turn is about a joint 45 with the tea sieve receiving element 33 connected. In the closed position, the second lever element 44 at an acute angle to the central axis of the tea preparation attachment 100 aligned. The first and the second lever element 41 . 44 close in the illustrated closed position an angle of about 70 °. In 6 It can be seen that the crank mechanism requires only minimal installation space. The elevation of the closure unit 20 opposite the plane of the pouring openings 15 is low, since it is only the first lever element 41 with the one-sided as a control element 21 molded key must be recorded. The closure unit 20 with the control 21 does not even extend to the level of the pouring edge 11 ,
  • The second lever element 44 has a lateral extension 44.1 with a hemispherical sealing element 44.2 , This presses in the closed position on a ventilation opening 36 in the top of the tea screen receiving element 33 ,
  • The sealing ring 31 down the tea strainer 30 seals against the central tube 13 from. Because the bottom of the tea strainer 30 is impermeable, is the tea preparation tower 100 thus already completely down towards the receiving space of the jug or vacuum flask, sealed. Through the sealing ring 34 and the sealed ventilation opening 36 is the volume between the bottom of the tea strainer 30 and the closed top of the tea screen receiving element 33 also completely sealed towards the top, so no liquid from the tea strainer 30 may leak to the outside, even if the jug or bottle with the tea preparation attachment 100 should have fallen over.
  • 7 shows the brewing position of the tea preparation attachment 100 with extended tea strainer 30 , Becomes the operating element 21 Pulled up, the first lever element pivots 41 around the axis 42 and with the joint 43 down, moves the second lever element 44 in a position parallel to the central axis and pushes over the tea screen receiving element 33 with the tea strainer 30 axially downwards. When the lever element 44 in the in 7 shown, axially parallel position is raised, lifts the sealing element 44.2 also from the ventilation opening 36 from. Because the perforated walls of the tea strainer 30 from the central tube 13 can be pushed out through the ventilation opening 36 Air and / or steam from inside the jug or vacuum flask from the closure unit 20 escape.
  • The tea strainer 30 Can in this position from Teesiebaufnahmeelement 33 be deducted, see 8th , Thus, the tea preparation essay 100 for normal use, the filling of tea leaves and the subsequent emptying of the tea strainer includes, not be completely dismantled every time.
