Abstract

The invention relates to a dispenser (Sp) comprised of a discharge opening (7) for fluidic or pasty materials (3), of a resilient elastic supply container, e.g. in the shape of a bottle (1), and of a self-sealing closure (V) which opens as a result of excess pressure in the material (3). The closure (V) can be moved out of a non-openable position and into an openable position by turning. In addition, the closure (V) is fastened to a bottle neck (2) having a bottle neck wall (11), and attains a functionally reliable configuration due to the provision of a closure slide (9) which can turn by overlapping (U) and with regard to the bottle neck wall (11). When in an opened position, said closure slide opens a discharge path (6) formed by the bottle neck wall (11).

Description

00001 DISPENSER WITH SELF-LOCKING CAP 00002

00003 The invention relates to a dispenser with

00004 opening for fluid or pasty masses, with a

00005 elastic resilient storage container, for example

00006 in the form of a bottle and a self-closing

00007 which opens due to overpressure in the mass

00008 closure, the closure by twisting

00009 of a non-revealable position

00010 bar, with the closure on one

00011 bottle neck wall having attached bottle neck

Is 00012. 00013

00014 A dispenser of this type is described in WO 94/27882

00015 knows. To the formation of the non-public position of

00016 closure underneath shoulder-like projections

00017 the same stationary counterhold of a screw cap

00018 designed in the form of a bottle storage container. In

00019 this position is the hole edge part of a central

00020 outlet opening like a valve seat against a fixed

00021 pulled the locking pin. One of the latter with

00022 formed exit path is thus kept outwards

00023 th, but open on the storage room side. The lock is in place

00024 on a resilient intermediate support, which, in the

00025 apparent position of the closure turned back,

00026 by the positive pressure of the mass, the releasing lifting

00027 of the closure allowed. This happens under axial

00028 Relocation of the intermediate carrier / lock unit. 00029

The object of the invention is to provide a generic

00031 dispenser advantageous in use and functionally reliable

To train 00032. 00033

00034 This task is first and foremost

A dispenser with the features of claim 1 solved 00036 by an overlap and relative to the bottle

00037 neck wall rotatable locking slide, which in

00038 the opening position through the bottle neck wall

00039 fertilized molded exit path releases. Here is the

00040 bottle neck directly in the closure mechanism with

00041 pulled. Intermediate links, such as a screw

00042 cap, can be dispensed with. In addition, the room can be

Use 00043 of the bottle neck. For example, as a stand

00044 device trained dispenser thus receives a practical

00045 height determined by the neck end. The covered

00046 kung to the bottle neck wall locking slide

00047 provides a simple, secure closure for

00048 storage room, advantageously at the beginning of the

00049 footpath already. First the willful twisting

00050 of the slide valve releases the exit path.

It is further proposed that the bottle neck wall

00052 in the overlap area with the slide

Has 00053 opening paragraph increasing over the circumference.

00054 This can be reached simply by shifting the wall

00055 bottle neck wall. Such measures can be

00056 can even be made in the blowing process. about

00057 the opening paragraph results on the one hand the counter

00058 closing surface of the slide and on the other hand

00059 the outlet-side space for the exit

00060 away. The procedure here was such that the opening

00061 paragraph, starting from a lowest point, over the

00062 extent is continuously increasing. Before-

Zug is a solution that the opening paragraph itself

00064 extends over the entire circumference. The locking slide

00065 is matched to this by placing the

00066 most point-capturing cross-sectional representation of the

00067 closure has an inclined front edge.

00068 This can practically be a crescent-shaped opening

00069 induce gap; on the other hand, it is the case that

00070 the front edge and the opening heel 00071 Overlap the final position to the full extent. In this

00072 take position front edge and increasing course of the

00073 opening section rectified bevel courses

00074 a. This is an advantageous embodiment

00075 achieved that the outlet opening partially through the

00076 bottle neck wall and partly through the internally

00077 half of the bottle neck wall extending jacket wall

00078 of the slide gate is formed. Furthermore,

Hen that the slide valve has a front end

00080 of the bottle neck wall radially on the inside with an overlap

Grips over part of handle. This produces an axial

00082 support and at the same time an additional rotary guide

00083 ne. It is also proposed that the training

00084 opening between the slide and the

00085 overlapping portion of the closure is formed. On

Another feature of the invention is that the

00087 slide valve forming an upward

00088 open channel in the overlapping section and in one

00089 blanket passes. The channel comes well in that

00090 the annular space of the fla-

00091 neck neck wall under. Regarding the exit route

00092 means closing outward proves to be one

00093 embodiment as cheap, according to the in the

00094 blanket a rebound the exit opening

00095 overlapping closure part is held. It can

00096 practically around ejje appropriately centrally fixed rubber

00097 act disc. Such a closure part can be

Assign 00098 easily because it is on the outside of the

00099 ke rests. A mechanically specially protected assignment

00100 voltage is reached when the cover is in the area

00101 of the closure part is recessed, such that the

00102 closure part essentially flat in a radial

00103 le continuation of the cover blanket passes over. It’s like that

00104 avoided any exposed position of the closure part.

In this context, it is also advantageous that 00106 in the area of the outlet opening in a support surface

00107 of the closure part is essentially radial

00108 opening port groove is formed, which

00109 provide constant access to the outlet opening

00110 det. So with simple means an air balancing

00111 path achieved, whereby the wall of the reservoir

00112 ters, i.e. the bottle, always in their original

00113 position can reset, so practically the same

00114 Crushing conditions to be achieved for each dispensing process

00115 gen. It is also advantageous if the closure part

00116 is formed from an elastomer. To achieve

00117 nier functional positions of the closure it proves

00118 is useful in that the closure limits the stroke

00119 can be rotated by approximately 180 ° or more. That leads to

00120 a clear distance between the two positions. The

00121 Means for this are simple and again with participation

00122 supply of the storage container, i.e. the bottle,

00123 bar by placing an outside in the bottle neck wall

00124 protruding limit cam is formed. Expedient

00125 ßig is a nose-shaped

00126 limiting cam, so that this still the function of

00127 Secure locking of the closure on the bottle neck

00128 men can, by simply the steeper flank of the nose

00129 acts hooking and the sloping back of the nose as

00130 run-in slope act for easier assembly

00131 can. The antidote on the closure side is such

00132 that the closure is concentric with the bottle

00133 neck wall extending ring wall, which with the

00134 limit cams interacting end stops

00135 points. The end stops are expediently end regions

00136 a slot opening extending in the circumferential direction

00137 solution. Two limiting cams are preferably provided,

00138 which are offset in the circumferential and height directions. So

00139 a leading guide path of approx. 180 ° is achieved.

00140 In addition, the counter-holding agent receives one in this way 00141 certain axial resilience. It is also proposed that the closure have a supporting wall which is supported on a shoulder on a storage container. 00144 can be used as an additional suspension source. In this regard, it is ultimately proposed that the closure in 00146 an end-of-rotation position with respect to the slot opening 00147 has a locking recess which relieves the tension between the 00149 spring force stored between the 00148 supporting wall and the reservoir shoulder. 00150 It is preferably in both end positions. For 00151, notches 00152 that are noticeable for the user are created, but on the other hand, overcoming the 00153 step between the snap-in receptacle and intermediate route is made easier 00154, since in this position the maximum tension 00155 does not act. On the way there is stronger friction00156. 00157 00158 The subject matter of the invention is explained in more detail below with reference to 00159 of two illustratively illustrated exemplary embodiments. It shows: 00161 00162 FIG. 1 a vertical section through the head region 00163 of a dispenser according to the first exemplary embodiment, namely in a position which cannot be opened by mere pinch pressure 00165, 00166 00167 FIG. 2 a representation corresponding to FIG. 1, in 00168 the apparent position transferred and when 00009 a pinch pressure is exerted on the bottle, 00170 00171 FIG. 3 is an enlargement of FIG. 2 in the area 00172 of the product outlet, 00173 00174 FIG. 4 is a vertical section through the head area 00175 of the dispenser according to the second embodiment 00176 game, in the position of the 00178 closure that is not in the position that can be opened by squeezing pressure 00177, 00179 00180 FIG. 5 showing the unwound ring wall of the closure 00181 as well as with the end cam 00182 in the end positions and 00183 00184 FIG. 6 the closure in a representation like FIG 4, each 00185 transferred to the open position at 00186 deliberately achieved product edition. 00187 00188 The dispenser Sp of both exemplary embodiments comprises a 00189 storage container, for example in the form of a bottle 00190 1, which merges into a clearly narrowed bottle neck 2 00191 to which a rotatable closure V is assigned 00192 net. 00193 00194 The medium held in bottle 1, a fluid 00195 to pasty mass 3, can be applied to the elastic, resilient wall 4 of bottle 1 by exerting a 00196 squeezing pressure. The corresponding volume reduction pushes the mass 3, going through the neck opening 5, into an outlet path 6, which opens into a 00200 final outlet opening 7. The 00201 dispenser Sp is expediently transferred to a falling position 00202 and the mass 3 is briefly struck in the head region ge00203, unless the dispenser Sp is generally intended to be ready via a head 00204. 00205 00206 The closure V is self-closing. Its closure part 8 in this respect extends over the outlet opening 7 00208 and is lifted up by the applied excess pressure in the mass 00209 3 (see FIGS. 2 and 6). 00210 To release the exit path 6, the closure V

00212 a slide valve 9. It is a rotary valve

00213 realized and an integral part of the

00214 neck 2 attached fastener V. 00215

00216 The locking antidote is a rotationally symmetrical

00217 sealing surface 10. This is in the area near the end of the neck opening

00218 5 of the bottle neck wall 11 realized. 00219

00220 In both exemplary embodiments, the locking slide

00221 over 9 hollow. In both cases

00222 len around a pot-shaped structure, the opening according to

00223 first embodiment shows on the pantry side and

00224 according to the second embodiment in the opposite direction.

00225 Nevertheless, for both solution variants there is the

00226 part of the adaptable mobility to the respective

00227 sealing surface 10 out. 00228

00229 To those with a smaller clear cross section

00230 sealing surface 10 closes on the mouth side of the dispenser Sp

00231 an opening paragraph 12. That is due to wall offset

00232 of the bottle neck wall 11 reaches what is in the blowing process

00233 is well considered. The larger accordingly

00234 zone with clear diameter provides the

00235 of the bottle neck wall 11 at said outlet

00236 way 6, which is blocked by the overlap and

00237 rotatable relative to the bottle neck wall 11

00238 locking slide 9. 00239

00240 The exit route 6 can be limited to one sector.

00241 ken or, as shown, as uninterrupted

00242 present annular space 13, which, with exception

00243 of a channel 14, from a ceiling 15 of the closure V

00244 is tightly sealed to the outside. Said blanket 15

00245 offers an overlapping section 16 there. 00246 The channel 14 is up, that is, the mouth side of the

00247 Spenders Sp open, forms the mentioned exit δff-

00248 tion 7, which from the local edge of the closure

00249 partly 8 is normally held. 00250

00251 The opening paragraph 12 is based on a horizontal

00252 level E-E, inclined (see FIG. 1). The oblique

00253 angle alpha is 15 °. The opening paragraph 12

00254 is, starting from a lowest point a over the

00255 extending the entire circumference, continuously increasing

00256 trained. The highest point has the reference symbol

00257 b. 00258

00259 The locking slide 9 has one in the deep

00260 most point a capturing cross-sectional representation of the

00261 closure V straight end edge

00262 9 '. It appears as a counter slope and has one

00263 equalize the angle alpha. The lowest point of the

00264 end face 9 'is denoted by c and the highest by d

00265 net. There is practically the structure of an obliquely

00266 cut pipe. The axial section of the opening

00267 tion paragraph 12, more precisely its inner step edge

00268 12 'to the sealing area of the front edge 9' is such

00269 that the storage space-side end edge 9 'and the opening

00270 opening paragraph 12 in the closed position (FIG. 1

00271 or Fig. 4) overlap to the full extent. The cover

00272 range is indicated in Fig. 1 with Ü. It lies

00273 a substantially oblique / parallel sealing system.

00274 The end edge 9 'is convexly rounded on the outside

00275 det, so that a welcome centering

00276 kung is present. 00277

00278 Fig. 2 and the corresponding counterpart of the second embodiment

00279 example show that the completion of the exit

00280 way to mass 3 is canceled when the two 00281 points a and d by turning the slide 9

00282 are in a neighborhood location. There results

00283 there is a sickle-shaped outlet opening 7.

00284 In this level it extends above

00285 also channel 14. 00286

00287 The outlet opening 7 is partially through the

00288 bottle neck wall 11 and partly through itself

00289 inside the bottle neck wall 11

00290 telwand of the slide 9 is formed. Recognizable

00291 sets the jacket wall of the slide 9 over

00292 a peripheral, horizontal ring web 18 in one

00293 concentric ring wall section 19 to the wall of the pot

00294 shutter slide 9 continues. This vertical one

00295 ring wall section 19 goes into the above,

00296 horizontal overlapping section 16 over which the end

00297 overlaps the end of the bottle neck wall 11. It

00298 arrives here to support the closure V.

00299 said front end. 00300

00301 The outlet opening 7 is between the locking slide

00302 over 9 and the overlapping section 16 of the closure V

00303 located. The second embodiment sees this

00304 regarding a basically the same solution, only that

00305 there the concentric ring wall section

00306 not to form a ring ring open to the outside

00307 groove 20 is formed. Rather, it is

00308 channel 14 there in the transition area between the wall

00309 of the slide valve 9 and the overlapping section 16. 00310

00311 The closing blanket 15 sits over the cross-sectional

00312 area of the bottle neck 2 continues radially.

00313 In this cross-sectional area, the closure cover 15

00314 sunk. The physical depression 21 takes that

00315 lying on the outside on the blanket 15, 00316 closing part 00317 8 lying more precisely in the depression 21. The axial depth of the depression 21 is matched to the 00318 thickness of the disk-shaped closure part 8, 00319 so that the closure part 8 ends essentially flat 00320 with a radial extension 15 'of the closure cover 00321 15. 00322 00323 Then the depression 21 is further developed in the sense of an air system. See Fig. 3 sen. There, the recess 21 forms in the area of the outlet opening 7, specifically in the area of a support surface 22 for the closure part 8, an essentially 00328 radially extending opening gutter 23. The 00329 goes over a corner and accordingly has a vertically aligned channel section 24. It is located in the edge wall 00331 of the depression 21. The channel 14 is connected downstream, 00332 the opening connection channel 23 connects to a return channel 00333 channel 25. The falls down to the vertically adjoining 00334 channel 14. Any excess mass 3 is sucked back from the area 00338 of the outlet opening 7 via the return suction effect which can be achieved when closing and also under the effect of the finite reset phase of the wall 4 of the bottle 00337 1. This effect 00339 occurs in parallel with the effect of the air equalization 00340 in that the connecting channel 23 forms a constant access 00341 to the outlet opening 7. If the wall of bottle 1 has reset, the closure V 00343 is moved from its open position to the 00344 non-open position by turning it. The container, i.e. 00345 Spender Sp, is then secured for transport. 00346 00347 The respective end positions of the closure V are 00348 stop-limited. The angle of rotation corresponds to approx. 180 ° 00349 or a little more. 00350 00351 The rotation limit is reached by a

00352 limiting cams 26. The latter is the bottleneck

00353 fertilizer 11 formed as a radially outwardly projecting nose.

00354 This is provided in pairs. So there are noses

00355 spotting limit cams 26 in diametrical opposite

00356 would lie, but with respect to a longitudinal central axis x-x of

00357 also rotationally symmetrical designed closure

00358 arranged axially spaced. 00359

00360 The limiting cams 26 engage in rotating guides

00361 slot openings 27 of the closure V. Latter

00362 are formed on an annular wall 28 of the same. The

00363 starts from the ceiling 15 and overlaps like a cap

00364 the neck 2 of the bottle 1. The offset,

00365 in the circumferential direction of the ring wall 28 parallel to the plane

00366 E-E extending slot openings 27 form with their

00367 end areas end stops 27 '(see FIG. 5). 00368

00369 The lower front edge of the ring wall 28 ends with a

00370 axial clearance to an intermediate

00371 shoulder 30 of the neck 2 of the bottle 1. Above

00372 this intermediate shoulder 30 is, at least in the first

00373 embodiment, the directly adjoining neck

00374 cut issued so that it is practically for the local one

00375 inside support of the ring wall 28 can serve.

00376 The corresponding concentric alignment of the ring wall

00377 28 is also at the level of the neck section, the

00378 above the seal-forming paragraph 12

00379 stretches. 00380

00381 The closure V is in an irreversible locking connection

00382 assigned. For this purpose, the limiting cams 26

00383 drawn. Their nose shape leads to an underside,

00384 horizontal locking edge 31 and to the plug-in

00385 opening relief slope 32 through the nose 00386 move. Attacks are made closer to mass 3.

00387 edge 27 '' of the slot openings 27. While the

00388 blocking edge 31 essentially perpendicular to the longitudinal center

00389 telaxis x-x of the donor Sp is aligned

00390 said edge 27 '' obliquely like a window sill

00391 outside. 00392

00393 The end positions are designed as locked positions.

00394 forms that can only be overcome with a strong will.

00395 For this purpose, recesses corresponding to

00396 exercises 33 of the edge 27 ''. Snaps into it

00397 the limiting cam 26 noticeably. The transition to

00398 higher part of the edge 27 '' can have a

00399 go slightly inclined so that the operation with reasonable

00400 bar force can be exercised. 00401

00402 The closure V has one on a storage container.

00403 shoulder 34 supporting support wall 35. This about

00404 all going support wall 35 extends concentrically

00405 to the shorter ring wall 28. 00406

00407 The one sitting on the reservoir shoulder 34

00408 end edge 35 'is chamfered with respect to its inner edge.

00409 So there is a softer lip-like structure.

00410 A resilience in the sense of a

00411 blocking edge 31 of the limiting cam 26 stressful

00412 Reaching force that locks onto the end

00413 strike 27 'or acts there the locking engagement.

00414 The corresponding load goes in as reaction force

00415 direction of arrow y. You can also in the

00416 ring wall 28 may be stored because of the overlapping

00417 arrangement of the elongated holes 27 of this body in

00418 a type of spring body is developed. First priority

00419, the support wall 35 has the compression 00420 property so that the supporting edge 27 ''

00421 blocking edge 31 can sniff perfectly. 00422

00423 From this constellation results that the closure V

00424 in a twisted end position with respect to the slot opening

00425 openings 27 in relation to the locking recess in shape

00426 of the depressions 33. 00427

00428 It remains to be noted that the elastomer or

00429 rubber existing closure part 8 via a central

00430 fastening device 36 on the ceiling 15 of the

00431 final V is held. The fastening device

00432 36 provides a rear connector, namely between

00433 see a locking head 37 and a counterhold 38. The

00434 locking head 37 can, as in the first embodiment

00435 preferred, be formed on the closure part 8 or,

00436 as preferred according to the second embodiment, on the

00437 sit there lower ceiling 15, which lower

00438 drawn section there the open towards the top

00439 final slide 9 represents. 00440

00441 The function is, briefly summarized, as follows: 00442

00443 For use, the closure V in one

00444 Revealed position allowing media exit.

00445 This opens the access for by squeezing the

00446 Bottle 1 displaced mass 3. The relevant gate

00447 is the entrance opening 17. Follow the exit path 6

00448, the bulging mass 3 lifts the closure

00449 gan, that is, closure part 8. It comes to the issue.

00450 If the pinch pressure decreases, what can be done by releasing the

00451 bottle is reachable, the negative pressure pulls it

00452 medium in the channel system back, whereby further

00453 via the bypass-like opening connection channel 23 along with

00454 channel section 24 of the air compensation takes place. By 00455 subsequent twisting into that shown in FIGS.

00456 closed position is again the desired sealing

00457 finally achieved. 00458
