HOLDER FOR FILTER BAGS
ABSTRACT OF THE DISCLOSURE:
A holder of elastic material for filter bags open at the top for preparing beverages, especially tea and coffee, which comprises a tubular stud having two oppositely arranged stud sections connected at their upper ends by an annular member and spaced from each other by a slot having two dia-metrically arranged slot sections while at least one manually operable spring-urged pressure member is provided which is adapted to press the stud sections toward each other to re-duce the diameter of the stud and thereby facilitate the placing of a filter bag on the stud. Advantageously the stud sections are provided with tapering surfaces to facilitate the slipping of a filter bag onto the stud, while barbs or the like are provided on the stud sections for piercing an in-serted filter bag and holding the same.
Description
~1~1'6B2 - The present invQntion relates to a holder o elastic material, especially synthetic material, ~or holding ~ fil~er bag for preparing beverages, such as tea and co~fee, while the filter bag with ~he tea leaves or ~he gr~md coffee immerses in-:~" to the hot water in the beverage container,or hot water is poured into or through the filt~r bag.
A heretofore known holder of ~he above mentioned generaltype has a tubular stud which ~apers at its lower end for holding a filter bag, and is provided with a slot or the like extending in axial direction of the stud for furnishing ~he possibility of decreasing the circumference of the stud against a sprin~ ~orce. Furthermore, this known holder h~s the upper end of the stud provided with extensions for placing the holder onto the rim of the beverage container. For limi.t-ing the placement of a ~ilter bag upon the upper end of the stud there is provided an annular broadened section. Further-more~ this holder has a handle by means of ~hich it can be handled a~d carried and also has a so-called pressing cam by means of which the stud can be reduced in circumerenc~ or can be compressed to a certain extent for facilitating the in-troduction of ~he stud into a filker bag or placin~ the filter bag onto the stud~
A drawback of this known holder described in German Ge-brauchsmuster 77 18 546 is that the oompressed or circume-rentially reduced stud oE the holder can be introduced only with difficulty into the opening o~ a filter bag known as a flat bag. For properly introducing and connecting a fil~er bag in~o and onto such a holder, a certai.n skill is required.
I _ ~Y~
Similarly~ also German Of~nle~ungsschrlft 20 17 606 dis-closes a one~pi2ce holder for holding a ~ilter ~ag for tea or cof~ee, which holder has a sSud Sapering ~oward its lower end.
Also i~ thls instance ~he holder is slotted in ~xial direction while the 3tud can likewise be redu~ed in its circumference against a spring force or can be compr~s~ed. Also this known hold~r ha~ the drawback ~hat, due to the relatively large and s~mewhat circular lower opening cross s~c~ion of the holder7 it is difficult to in~roduce the same lnto a fllter bag know~
as fl~t bag.
I~ is~ therefore, an object of the pre~ent invention to provide a holder of the abo~e mentioned general type which can easily and safely be handled ~nd which will permit the faste~-ing of a flat filt~r bag to the holder ~n a simple manner and in a minimNm of ime without requlring any particular skill.
This object and other objects and ad~antages o She in vention will appear more clearly from the following specific~-tion ~n connection with ~he accompanying drawings, in which:
Figure 1 is a~ isometric top view of a holder according ~o the present ~nvention.
Figure 2 shows the holder of Figure 1 as seen from below.
Figure 3 ~hows an isome~ric top view o the filter o~
Figs. 1 and ~
Figure 4 ShoW8 a modification of the holder of Figs.1~3.
By one a~pect of thi~ inventlon, there is provided a holder of elastic material for 11ter bags open at one end ~ 2 ~
for preparing beverages, especially tea and coffee, Which includes: all of one piece, a tubular stud for receiving and .
holding a filte.r bag, said stud havlng an upper part with radially outwardly extending means for resting on the opening rim of a vessel intended to receive the beverage and for limiting the slipping-on movement of this filter bag onto said stud, said tubular stud also having a lower part con-nected to said upper part and provided with an axial slot therethrough dividing said lower part into two sections, the lower end of said two sections respectively comprising two end surfaces inclined relative to the longitudinal axis of said stud so as to define with each other a wedge-shaped end region facilitating the slipping of a filter bag onto said stud, and resilient actuating means operable selectively to move said two sections toward each other against the resili-ent force thereof to facilitate the slipping of a filter bag onto said stud and subsequently to allow the resilient force of said resilient actuating means to spread said sections apart so as to cause said sections to hold a slipped-on bag on said stud.
A holder according to the present invention has the advantage that it can easily be introduced into a filter bag which is designed as a flat bag. To this end it is merely necessary to press the two handle sections together to thereby reduce the diameter of the stud or its circum-ference, whereupon the wedge-like or cutting edge-like end B~
. ..
regiom of the s~ud can be slipped between the two sides of the filter bag which lie one upon the other ~ile g-r~du- ;
ally w~dening the opening of the fil~er bag~ The narrow through-flow cros~ section formed by the wedge-like or cutting edge-lilce end region of the stud brings about ~
certai~ co~ rol of the wa~r flow when pouring the water into the stud, This helps to preven~ the filter bag will be torn of rom the holder due to tos strong ~ flow of the w~ter.
According to a further development of the i~v~nt~on, ~he stud ends ~t it8 upper ~nd in a hollow a~ular flange.
In this way a sa3fe abul;ment will be formed when slippi~g a filter bag onto the stud or introducing the stud into a filter bag. Irl addi~cio~ therets" there is also obtained the possibility of placing the holder upon the rim of beverage con~ainers having diferent opening diameters.
A further and im~roved e~bodiment of ~he imTention is characterized in that the s~ud has a second 810t located diametx~cally opposite ~he first slot of the stud7 ~hich 20 second slot extends from ~he lower end of the s~ud to about the flaa~ge so that: two ~tud section~ are formed, a~d that parts of the flange serve as resllient connectlng piece or the two stud sections4 In this way it i8 possible e~sily to adjust the spring ~orce of the in particular one-piece holder of sy~hetio material in the region of i:he connect-ing piece, if this should be nece~sary. ~ur~hermore, in co~'crast to a holder wi~h only one slot in the stud~ ma~erial is bei~g sav~d in the production of th~ holder~
~ ceording to a still urt~er d~velopment of th~ present inve~on) the resilient co~Qecting piece ~ the ~ame ~cime forms ~n extension for placing ~he hold~r upon the r~m of a b~verag~ container. A~ a r~sul~ thereof" ~h~ com~ cting piece together with that region of the h~ndle which is ~d~
~acent ~o the ~tud ls adapted beyond the flange to serve as support for the holder on the beverage container.
~ccordin$ to a preferred embodiment o the invention, the flange oll one side of the ~lot end~ in a handle and on the other side of the slot ends in a pr~ssure member which ~xterlds in the direction o Jche handle. This pressur~ mem~er confines a recess in the handle in such a way ~hat th~t sid~
of the pressure member which f~ces away froTn the handle to-gether with the adj~ceTIt longi~udinal side of the h~T~dle, which lox~gitud~nal side is adJacent to the rece~s, is located approximat~ly in one plane. That side of the pressure member ~hich ace~ the handl~ is ~paced from the oppositely located 20 later~l p~rt of the h~ndle by about the wid'ch of th~ slok.

For oper~ti~g the pr~sure member7 the chumb of the hand gr~spin~ the handle of the holder ha~ only ~lightly to be pre~sed against 'che pressure me~ber. On the other hand, th~ pressure member ls so Arr~nged th~t lt cannot be ~ 5 --~actuated accid~nt~llyO
Fs)r furthe~ securirlg the filter bag on ~he stud~ i~c is suggested ~ t the -~tud or the s'cud sect~o~s be provided with on~ or mor2 barb~ ke protrll~ions whlch, wh~ pres~i.ng ~he pres~ure member inwardly, will penetr~te inte~ the filter bag at the op~nillg are~ ~hereo~.
Accordin~ to still ancth2r embodirnent of the i~ention"
the fl~nge formc a ring closed in itself while he han31le o the embod~eI~t of Figs,, 1, 2 and 3 has been replarsd lû by ear~ formia~ p~rt of a slotted collar oonnected to $he closed ring. These ears ~re located diame~rically oppos~te to each other. ~hen with this holder ~he filter bag is in-troduced, the stud wi~11 upon ac~ua'cion of the ears change its respective cross section unevenly ~nd, more specifi-callyQ at an increas~ng rate from the upper to ~e low~r end o the stud.
Referring now to th~ drawmgs in det~il aad E'ig9. 1 to 3 thereof ~ particular, the~e figures show ~ holder 1 for hold-ing a filter bag 2" especi~lly a filter bag designed as a 20 flRt bagO ~ holder 1 prim~rily omprises ~ stud 3 with a slot 4 and ~ h~ndl~ 7 o~ o~ae side o~ the slot 4 arld furlther-mt)re comprise3 a pressure member 16 on the other ~ide o th~
slot 41~ In ~ddition to being provided with ~he ~lot 4, the stud 3 is ~lso provlded with a diametrically oppositel~ lo~
c~l:ed slot 23 so that the ~tud 3 is subd~:Lded into stud ~,j,,j., seetions 14 and 15. The stud sections 14 and 15 are through a resilient co~necting member 13 connected to each other. Parts of the handle 7, o the pressure member 16 and of the connect~
ing member 13 fo~m supports 5 and 6 for resting the holder on the opening rim of a vessel intended or receiving the beverage.
The conneoting member 13 forms a resilient semicircular section 12~ Fur~hermore that p~rtion of ~lange 11 which i~ located opposite to the connecting member 13 forms the pressure member 16.
The stud 3 is approximately cylindrical and slightly co-nical. The lo~er end of the stud 3 is on one and/or the other side of slot 4 provided with oppositely located sur~aces 8 and 9. The sur~aces 8 and 9 are inclined with regard to the lon-gitudinal axis of stud 3 in such a way that a wedge-like or cutting edge-like end region of the stud is formed which acili-tates the introduction of the stud 3 into a fllter bag. By actuating the pressure mem~er 16~ which means by moving the pressure member 16 toward the handle 7, the lower opening cross section which is already relatively narrow will be re-duced further so that the stud in this condition can easily be introduced into a filter bag without requiring any parti-cular skill~ After releasing the pressure member 16, the re-silient connecting member 13 relaxes while increasing the open-ing cross section of the stud 3 so that ~he filter bag 2 pl~ced upon ~he stud 3 will now be tigh~ly held and expanded around the stud 3 and will be firmly grasped by the holder 1, The hollow annular flange provides a safe limitation or abutment ~or the filter bag being placed upon the stud 3 or ~ 6 the holder 1~
The pressure member 16 of holder 1 is located within a re-cess 17 provided in the handle 7~ That side 18 of the pressure member 16 which aces away from the handle 7 is in subska~tial alignmPnt with ~ha~ longi~udinal side of ~he handl~ 7 which is adjacent to the recess 17 or is located in one plane with this longitudinal side. That side 19 of the pressure member 16 which faces the ha~dle 7 i5 spaced from the oppositely located lateral part 24 of the handle 7 by a distance approximately equalling the wîdth Qf the slot 4 or the slots 4 a~d 23 i~ the stud 3 The stud 3 has lts sections 14 and 15 provided with barb~
like pro~rusions for piercing the filtex bag 2 in the opening or mouth region.
Fig. 4 shows a modification of a holder 25 which di~fers from the embodiment of Figs. 1-3 primarily in that it does not have a handle and ~pring section similar to hand~7and spring section 13 of Fig. 1. Ins~ead, the upper section of ~he stud 26 is provlded wi~h a ring~shaped section 32 which has a ~ollar 3S. The collar 35 is provided with cutouts 39 and 40 and has ears 33 and 34. The cylinder-shaped and/or slightly conical stud 26 has, similar to the holder 1 of Figs. 1 to 3, its lower - end provided with oppositely locat~d surfaces 29 and 30 which form a wedge-like or cutting-edge-like re~ion 31. The stud 26 has slots 27 and 28, and the holder 2S has areas 36 and 37 on the ring~shaped section 32 which serv~ as resilien~ colmecting members for the stud sections 38 formed by the slo~s 27 and 28.
By pressing the ears 33 and 34 toward each other, which ears act as pressure memb~rs~ the openlng cross section in the lower _ 7 _ ~region of the stud can be reduced fur~her so that the stud 26 of holder 25 can easily be întroduced into the ~ilter bag produced as flat bag.
It is~ of course, to be understood that the present in~
vention is by no means limited ~o the par~icular showing in the drawing~ but also encompasses any modifications wlthln ~he scope of the appended claims.
Thus it i5 for ins~ance possible to produce the ~tud with the wedge-like or cutting-edge-like end region not out of the ~ull, but ~he s~ud may also be made of correspondingly extend~
ing strutsO Fuxthenmore, it may be advantageous not to make the end region of ~he stud rectilinear; but to make ~he end region slightly roundedO
A heretofore known holder of ~he above mentioned generaltype has a tubular stud which ~apers at its lower end for holding a filter bag, and is provided with a slot or the like extending in axial direction of the stud for furnishing ~he possibility of decreasing the circumference of the stud against a sprin~ ~orce. Furthermore, this known holder h~s the upper end of the stud provided with extensions for placing the holder onto the rim of the beverage container. For limi.t-ing the placement of a ~ilter bag upon the upper end of the stud there is provided an annular broadened section. Further-more~ this holder has a handle by means of ~hich it can be handled a~d carried and also has a so-called pressing cam by means of which the stud can be reduced in circumerenc~ or can be compressed to a certain extent for facilitating the in-troduction of ~he stud into a filker bag or placin~ the filter bag onto the stud~
A drawback of this known holder described in German Ge-brauchsmuster 77 18 546 is that the oompressed or circume-rentially reduced stud oE the holder can be introduced only with difficulty into the opening o~ a filter bag known as a flat bag. For properly introducing and connecting a fil~er bag in~o and onto such a holder, a certai.n skill is required.

Also i~ thls instance ~he holder is slotted in ~xial direction while the 3tud can likewise be redu~ed in its circumference against a spring force or can be compr~s~ed.

2. A holder according to claim l, in which said upper part includes an annular flange.
3. A holder according to claim 2, in which said slot has two diametrically oppositely located slot sections extend-ing through the axial length of said lower stud section, por-tions of said flange serving as resilient connecting member for said stud sections continuously urging the latter apart.
4. A holder according to claim 3, in which said resili-ent connecting member forms an extension of said upper part for supporting said holder on a beverage receiving container.
5. A holder according to claim 2, in which said flange on one side of said slot has connected thereto a handle provi-ded with a recess adjacent said flange and in which on the other side of said slot adjacent to and opposite a portion of said handle said flange has connected thereto a pressure member at least partially located and movable in said recess, said pressure member having that side thereof which extends in the longitudinal direction of said handle and faces into said re-cess spaced from the opposite handle wall portion by about the width of said slot.
6. A holder according to claim 5, in which the lateral outer side of said pressure member and the adjacent lateral outer side of said handle are located in about the same plane.
7. A holder according to claim 1, in which said stud is provided with barb-shaped projections for piercing an in-serted filter bag.
8. A holder according to claim 1, in which said upper part includes an annular strip of resilient material closed in itself and also includes a collar with two diametrically oppositely located slots and two oppositely located ears form-ing pressure members operable to selectively press said stud sections toward each other, said ears respectively being lo-cated between said slots.
