Abstract

A cap (V) for bottles (2) of injection liquids (substance 1) or the like has a sealing disk (D) capable of being pierced arranged between the bottle neck (3) and a closing ring (5) that surrounds the opening of the bottle and has a central opening (12). A supporting surface that faces the centre (Z) of the sealing disk (D) allows the sealing disk (D) to be easily pierced and at the same time securely retains it on the bottle opening.

Description

00001 closure on bottles for injection liquids or

00002 the like

00003

The invention relates to a closure on Fla¬

00005 for injection liquids or the like,

00006 which one between a crimp ring with free

00007 insertable center opening and the bottle neck lying

00008 piercing seal.

00009

00010

A closure of this type is through DE-OS 35 19 655

00012 known. The rubber elastic piercing seal is

00013 there in the form of a seal in the neck of the bottle

Incoming plug designed, which is above the

00015 end edge of the bottle neck fort¬ in a ring collar

00016 sets. A small one goes from the ceiling of the ring collar

00017 ring rib out. The latter is achieved through beading and

00018 geometrically triangular in cross section. It is a

00019 equilateral triangle in front. The one in the soft material

00020 of the plug penetrating part of the annular rib

00021 an annulus by material displacement. Sense and

00022 purpose of this just exposed to a material thickness

00023 ring rib is creating a seal, so

00024 lock opposite ascending at the neck of the bottle

00025 germination. The one in the forerunner mentioned as a plug

Plugs designed in 00026 not only require a considerable amount

00027 Chen cost of materials; he's also with that in mind

00028 piercing a cannula etc. problematic.

00029

00030 In order to reduce the penetration resistance, there is

00031, for example, by US Pat. No. 3,587,897, the proposal

00032 the central area of the stopper to the interior of the bottle

Hollow out 00033.

00034 00035 Even with bottles with smaller diameters

00036 a flat, thin sealing washer instead of a plug

Used 00037, which peripherally on the front edge of the Fla¬

00038 rests on the neck and by means of the crimp cap ring

00039 is held there clamped. Here, however, results

In practice, the problem is that when pressing so-called

00041 ter Spikes the related piercing seal

00042 Halt loses. This can be the case with spikes with a diameter

00043 water up to 5.8 mm even go so far that such

00044 sealing washer is pushed into the bottle. In order to

00045, however, the seal on the bottle neck would be eliminated,

00046 a removal of the

00047 then unprotected content of the bottle is no longer possible

00048 be.

00049

Knowledge of this problem exists according to DE-OS 32 12

00051 685 the proposal to make the sealing washer particularly thin

To train 00052. But that in turn requires commitment

00053 of a plate-shaped, relatively dimensionally stable support

00054 partly to ensure sufficient dimensional stability near the edge

To achieve Kleimτ-fastening and sealing area.

00056

The object of the present invention is a gat¬

Specify the closure according to the invention, which is easier to carry through

00059 shockable and still well kept, this is essential

00060 slightly simplified design.

00061

This object is achieved by the in claims 1

00063 and 4 specified invention.

00064

00065 The subsequent claims give further inventions

00066 features according to the invention.

00067

00068 As a result of such an embodiment, it is of use

00069 ler, material-saving closure achieved. Next to the 00070 there is an advantage of minimizing the piercing forces

00071 reliable sealing in the edge area before and before

00072 all a high-class bondage compared to disc storage. According to the first proposal, this has been achieved

00074 through a face towards the center of the piercing seal

00075 th support surface of the same. The otherwise over the stopper

00076 projection achieved bracket is now by a holding

00077 tion, which can even be a form-fitting bracket,

00078 between crimp ring and disc replaced. in the

00079 with regard to a form-fitting holder proves to be

00080 embodiment as advantageous in that a

00081 ring rib of the crimp ring as a support surface

00082 the top of the piercing seal is engaged

00083 to an annular space at the top of the piercing seal

00084 tung. In a more concrete form, this looks like this

00085 from that designed as a flat disc, only by

00086 overlay on the front edge of the bottle neck with this

00087 piercing seal in contact with a

00088 preformed annular space forms side surfaces that

00089 angled or almost perpendicular to the top of the

00090 piercing seal run in and each of which

00091 lying on the outside, further away from the center

00092-sided side surface as a support surface on the outer surface

00093 a ring rib of the crimp cap with a smaller cross section

00094 pen ring is present. Such a pushing in of the shit

00095 be avoiding positive locking can even a certain

Have 00096 game. This has a self-centering effect on

00097 the disc and facilitates assembly. In finished

00098 assembled state, so after flanging the edge of the

00099 crimp ring provide the appropriate clamping

00100 also forces the desired seal. A second

00101 proposed solution consists in that the

00102 cut S-shaped angled disc

00103 piercing seal on the front edge of the bottle neck

00104 ses and on an inside bevel 00105 rests and in the area resulting from the S-shape

00106 the ring shoulder on top of the same the ring

00107 rib of the crimp ring presses in such a way that

00108 right-angled or almost right-angled ring rib

00109 flanks are given in the area of that

00110 cuts the puncture seal that is on the outside

00111 of the inside bevel of the bottle neck

00112 stretches. The restraining elements are formed here in the course of the train

00113 of the flaring process. It is also proposed that

00114 the ring rib is designed as a curved section.

00115 Such a bulge can be seen when pulling the flare

00116 Take into account the cap ring. moreover

00117 it proves to be advantageous that the opening

00118 cross section of the ring rib at a ring bead

00119 the inner surface of the piercing seal and

00120 crimp cap ring overlapping cover cap opposite

00121 lies. It happens even with longest storage times

00122 not to lift the annular rib from the annular space.

00123 The ring bead comes in the existing ring space

00124 the ring rib under. A cheap variant for the formation of the support 00125 is that the latter from a

00126 inner surface of an outer surface of the bottle neck

00127 overlapping wall extension of the disc is formed

00128 is. That goes into a more cap-like shape

00129 the disc over using the bottle at the same time

00130 sealing counterhold. To do a peripheral job

00131 to prevent gene of the wall extension has been found

00132 an embodiment as advantageous that the outer surface

00133 the bottleneck the bottom of a peripheral circumferential

00134 paragraph that receives the wall extension. The

00135 captivating section of the crimp ring can so

00136 are pulled through at the same level. The overlap outside

00137 the solutions are further characterized by a

00138 Support of the outer surface under the center

00139 teter tension / preload. In order to do this regarding the 00140 piercing area of the disc an eardrum or

00141 membrane-like tension with the corresponding disadvantage

00142 an expansion of the piercing hole is excluded

00143 a related measure characterized by a

00144 between the edge of the center opening and the front edge

00145 lying voltage equalization reserve. The latter can

00146 specifically due to a deviation in the extension of the pane

00147 be formed, for example in the form of a Z-shaped

00148 bevel, an S-shaped corrugated structure, self-

00149 dend rotationally symmetrical. With regard

00150 the cross-bottle connector assignment proves it

00151 is advantageous that the wall extension under

00152 Formation of a funnel-shaped display on the assignment side

00153 tung is easily issued. To prevent the

00154 relatively thin-walled wall extension itself

00155 rolls up, it is proposed that the jacket wall

00156 of the wall extension in the area of the free end

00157 the same has an annular bead. It works like a

00158 Ripe. In this regard, an advantageous embodiment is also

00159 design achieved by a second, axially beabsta-

00160 nd, leaving a peripheral ring trench

00161 bead. This not only brings beneficial

00162 balancing in the clamping assignment, but lets

00163 also a rational pre-assembly. That brings the

00164 invention or proposal that the ring beads be

00165 are the same and from the wall of the crimp ring

00166 are friction locked. The one made of aluminum

00167 existing crimp ring can therefore be operational

00168 quite pre-equip, i.e. combine with the disc.

00169 Finally, there is an advantageous embodiment

00170 tion in that the second ring bead, the top

00171 slightly increasing the disc, into this upper side

00172 is running. This results in a deflecting pressure component for

00173 the cheek-like overlapping wall neck

00174 extension. The object of the invention is based on

00223

00224 The shown with for infusion, transfusion or

00225 injection of certain substance 1 filled bottle 2

00226 goes in the usual way in a narrowed bottle

00227 neck 3 over. Its opening 4 is closed with a cap.

00228 The closure is designated V in its entirety. 00229

00230 components of the closure V are a crimp cap

00231 ring 5, a rubber-elastic disc 6 as a sealing element

00232 ment as well as a covering cap 7. 00233

00234 The crimp ring 5 is made of aluminum. His

00235 accordingly plastically deformable lower edge 8

00236 engages under a retaining bead 9 at the upper end of the bottle

00237 neck 3 and thus places the peripheral on an upper

00238 front edge 10 fixed disc 6 firmly. It follows

00239 a sealing pad, long-term support

00240 due to the clamping force of the crimp ring 5. 00241

00242 The upper edge 11 of the rotationally symmetrical rectangular

00243 designed crimp ring 5 leaves in its hori-

00244 central part a circular central recess 12. 00245 This provides proper access to the inside

00246 of bottle 2 or substance 1, namely after

00247 deduction of the originality assurance

00248 end cap 7. The latter adheres to the top

00249 edge 11 of the crimp ring 5 engaging holding

00250 tongues 13 on this firmly. A will is needed

00251 emphasized trigger under reaching one the necessary

00252 wall 14 providing gripping surface and thickened for this purpose

00253 the flat, pot-shaped, protective cover cap

00254 pe 7. The latter is made of plastic. Your lower grip

00255 rand means 14 '. 00256

00257 After the central recess 12 has been exposed accordingly

00258 can act as a piercing seal D.

00259 6 are pierced by the cannula or a spike.

00260 This happens on the one hand due to the low level

00261 thick disc 6 without much force

00262 and also without risk of knocking the disc 6 in

00263 the inside of the bottle 2. 00264

00265 On the other hand, there is also a negative pressure

00266 unable to hold the peripheral

00267 clamped pane secured above the front edge 10

00268 to move 6. There is a positive engagement.

00269 This is achieved in all of the exemplary embodiments

00270 facing the center Z of the push-through seal D.

00271 support surface of the same. Center Z is defined by the longitudinal

00272 central axis y-y of the bottle 2 defined. Disk 00273 crosses this axis. The support surface is concentric, 00274 parallel to the axis y-y.

00275

00276 The interlocking engagement takes place between a ring rip

00277 pe 15 of the crimp ring 5 and an annular space 16

00278 of the piercing seal D speak disc 6. Regarding

00279 of the ring rib 15 is a material made of 00280 rial of the crimp ring 5 bulged section,

00281 is practically a circumferential, inside, i.e.

00282 the interior of the crimp ring 15 going or

00283 directed bead. 00284

00285 The congruent annular space 16 is in the

00286 top 17 of the disc 6. Its depth is about

00287 third of the slice thickness. 00288

00289 According to the first exemplary embodiment (FIG. 3), the ring

00290 space 16 preformed on the disc 6. The cross section

00291 of the annular space 16 is such that it is lateral

00292 forms 16 'and 16' 'flanks that are rectangular or

00293 almost at right angles in the aforementioned top 17 of the

00294 Run in piercing seal D. Already in the flare

00295 position, but at least under piercing stress, in

00296 which is an inward tensile component in

00297 in the direction of arrow x is the same

00298 aligns with the outer flank 16 'running outer surface

00299 15 'of the ring rib 15 of the stock exchange with a smaller cross section

00300 delkappen ring 5 blocking in front of said side flange

00301 ke 16 '. The slightly exaggerated light gap

00302 serves to clarify the contours of 15 and 16. 00303

00304 As can be seen from the drawing, it occurs beyond

00305 of the annular space 16, the central recess 12

00306 facing section 17 'of the top 17 of the disk 6

00307 directly against the corresponding inner surface of the

00308 horizontal ring wall 18 of the crimp ring 5.

00309 This section 17 'is significantly higher

00310 as the inner side of the annular space 16

00311 section of the top 17. The corresponding thickness

00312 terschied results from the drawing and makes

00313 lent it at least the thickness of the top edge

00314 corresponds to 11 engaging retaining tongues 13. 00315 Above the ring wall 18, referred to above as horizontal

00316 1st part, the same is supported by

00317 the section of the cover cap 7 there

00318 but not for a continuous system; rather is

00319 this section except for radially molded support ribs

00320 19 cleared out deeper. These radially aligned support

00321 ribs 19 lie full with their combs on the Obersei-

00322 te of the ring wall 18. The support ribs 19 result

00323, as far as the arrangement is concerned, from FIG. 2. 00324

00325 The support ribs 19 are in circulation in the central area

00326 direction in connection with one of the cover cap 7 in the 00327 area of the mentioned clearance formed ring bead

00328 20 in connection. The annular bead 20 runs at a distance

00329 above the bottom of the ring rib 15; he sticks out

00330 table just in the entrance area by arching

00331 or deep drawing generated, the annular rib 15 forming

00332 surround. The non-contact partial entry goes

00333 particularly clearly from FIG. 4. The one in the

00334 cut approximately semicircular ring bead 20 overhangs the

00335 intersecting support ribs 19, which are also in the transverse

00336 cut semicircular to make the double

00337 te. The zenith of both semicircles is on the bottle side. 00338

00339 As can be seen in the drawings, the forehead

00340 edge 10 an outward slope gradient.

00341 The angle of inclination alpha is approx. 5 degrees. The trailer

00342 end, ie underside edge area of the pane 6

00343 follows this slope, so that its outer edge 21, the

00344 to directly in front of the essentially cylindrical 00345 wall 22 of the crimp ring 5

00346 is sufficient, there has a greater thickness than in the loading

00347 rich of the inside beginning, the inner edge 23 of the

00348 obliquely outward sloping edge 10 so.

00349 This results in an advantageous clamping voltage 00350 and thus gasket-increasing wedge effect, which

00351 ge of the rotationally symmetrical circulation of the thickening

00352 has the same effect on all sides. 00353

00354 In the first exemplary embodiment (FIG. 3), the interior

00355 surface of the cap 7 in the area of the center recess

00356 ung 12, entering this, pulled forward on the pane side.

00357 The inside further forms a sealing bead 24

00358. This is triangular in cross section, the

00359 a slightly longer triangle side in the inner surface

00360 of the cap 7 is rooted. The sealing bead 24 occurs

00361 partially in the soft-elastic material of the disk 6

00362 a. 00363

00364 The closure V according to the second embodiment (Fig.

00365 7) is basically the same structure. The reference numbers

00366 are used analogously, partly without the textual

00367 remarks on the first embodiment to be repeated

00368 len. 00369

00370 A structural difference is that the

00371 be 6 partially in the area of the opening 4

00372 is lowered, using a level offset

00373 zes. The accessible through the central recess 12

00374 piercing area of piercing seal D is

00375 over the cap 7 leaving a free space

00376 25 vertically spaced. Through this level offset

00377 is rotationally symmetrically peripheral in the transverse

00378 cut Z-shaped angled disc 6. The higher

00379 end of the disc lies on the front edge 10

00380 of the bottle neck 3 supported and sealing. The

00381 but the support surface is enlarged as well

00382 another one on the inside to the above-mentioned inner channel

00383 te 23 subsequent waste falling into the opening 4

00384 bevel 26 is used. The bevel 26 creates 00385 a funnel and extends at an angle of

00386 approx. 45 degrees to the longitudinal central axis y-y of the bottle 2. 00387

00388 The from the Z-shape shown schematically in FIG.

00389 gene bend 27 emerging ring shoulder 28 rests

00390 on the blunt section of the through the retaining bead 9

00391 significantly widened forehead edge 10. Also lies here

00392 the ring rib 15 in the superstructure of said front edge

00393 10. The latter could also diagonally outwards

00394 be designed to fall off. 00395

00396 A further measure relating to the ring rib 15

00397 me is now that the ring rib 15 of the flare

00398 cap ring 5 the rubber-elastic disc 6 such

00399 impresses that rectangular or near rectangular

00400 standing ring flanks 29 are given. They are in the

00401 area of that section of the push-through seal

00402 D, which is still on the outside of the inside chamfer

00403 gung 26 of the bottle neck 3 extends. In the Kle m

00404 position, the adhesive force does not go into the

00405 gen area, formed by the bevel 26. Here too

00406 is therefore a functional restraint 00407, especially given by the outer ring flank 29, and

00408 because of the steep-sided shape of the ring rib 15,

00409 which are their disc-side, the side flanks

00410 16 ', 16' 'comparable counter side flanks themselves

00411 presses. 00412

00413 The disc side, the same helix angle as

00414 the bevel 26 supporting surface is with 6 *

00415. It sits in the direction of opening 4

00416 of the bottle neck 3 continued in the same direction, in total

00417 forming a self-centering cone, so that

00418 itself when the disc 6 is placed,

00419 rigged. 00420 The piercing load goes beyond the as

00421 bevel with rotationally symmetrical tipping bearing

00422 26 in a pressing contact directed against the ring rib 15

00423 component about. This increases the sealing and the

00424 final interlocking of ring rib 15 and

00425 the ring groove she pressed in, comparable

00426 the annular space preformed in the first embodiment

00427 16. 00428

7 also applies that the ring flanks 29

00430-forming outer surfaces despite slightly upward

00431 divergence quite steep, i.e. almost perpendicular to

00432 extension plane of the generally flat designed

00433 be 6. 00434

00435 The bottom of the annular rib 15 produced by beading

00436 of the solutions is rounded (concave when viewed from above).

00437

00438 From the aspect of creating the retention elements

00439 the ring rib 15 can also be interrupted or even in

00440 form of a row of warts can be realized, this in close

00441 Follow the warts, of course. 00442

00443 The closure V according to the third embodiment (Fig-

00444 ren 8 and 9) is also basically the same structure

00445 it. The reference numbers are used analogously to

00446 part without repeated text. 00447

00448 The disk 6 according to Figure 8 has the one described above

00449 Z-shaped bend 27 opens, goes outwards

00450 tet in the ring shoulder resting on the front edge 10

00451 ter 28 and continues beyond. 00452

00453 This is one of the disc 6

00454 shaped wall extension 30. The latter learns about the latter 00455 washer 6, its outward shift here

00456 support. The center Z of the piercing seal D

00457 facing support surface is from that of the above

00458 flank 16 'comparable inner surface 31 of the fl-

00459 neck extension 3 overlapping wall extension 30

00460 det. That of the outer surface 15 'of the annular rib 15

00461 bare outer surface of the bottle neck 3 or retaining bead

00462 9 means 32. Said outer surface 32 is removed from the center

00463 turns. 00464

00465 The wall extension spanning the outer surface 32

00466 30 extends essentially only over half

00467 height of the retaining bead 9 and closes with its flat

00468 ring side 33 facing the same side as the

00469 bottom of the funnel-like disc 6. 00470

00471 The inner edge of the wall extension 30 is chamfered,

00472 this to facilitate the assignment of the disc 6 with tension / preload 00473.

00474

00475 The variant shown in FIG. 9 is only available in

00476 Chen details modified by there the outer surface 32nd

00477 of the bottle neck 3 or retaining bead 9 from

00478 reason of a peripheral circumferential paragraph is formed.

00479 The paragraph bears the reference number 34 and is located 00480 in the area of the outer upper edge of the retaining bead.

00481 stes 9. This has the advantage of the cylindrical alignment

00482 device of the wall 22 of the crimp ring 5. The

00483 outer edge 21 of the disc 6 is thus aligned with the

00484 outer surface 32 of the retaining bead 9. According to FIG

00485 a downward constriction of said

00486 wall 22 in front, ending in the edge 8, which the holding

00487 bead 9 reaches under. 00488 00489 Both solution forms of the third embodiment

00490 is a measure in common that, despite a tension around the disk 6, keeps the area of the disk intended for piercing 00492 practically tension-neutral 00493. This is achieved by a between the edge of the

00494 center opening 12 and the edge 10 lying chipboard

00495 compensation reserve R. This is given in FIG. 8 00496 by changing the direction of the disk profile in the approach

00497 Close to the inside edge of the bottle neck 3. The at the

00498 spill over of the bottle neck against the

00499 restoring force of the material

00500 tion of the wall extension 30 is over there

00501 slope compensated. This slope is in the second

00502 example as a rotationally symmetrical Z-bend

00503 27. 00504

00505 In the embodiment shown in FIG. 9, said tensioning

00506 compensation reserve R of a V-shaped cross-section

00507 structure, which is a continuous ring

00508 wave continues, for example a bellows-like membrane

00509 similar. The V-opening is directed upwards. The

00510 V-legs are significantly smaller than

00511 the remaining parts of the disc 6, such as the

00512 passage area or the area reserved for bondage

00513 area, i.e. wall extension etc. This extension

00514 deviation is therefore not only in one leg

00515 direction as shown in Figure 8, but in two

00516 divergent leg insertion directions. The V-

00517 crown is rounded and follows one on the inside

00518 from the underside of the disc 6 retraction

00519 35. Here too, the V-part closes at approximately the same height

00520 with which on a shoulder 36 of the retaining bead 9

00521 supporting ring edge 33. 00522 00523 When piercing a cannula or a spike comes

00524 because of a tension-neutral situation of the

00525 piercing area does not widen the self-

00526 punched hole. 00527

00528 The closure V according to the fourth embodiment

00529 is structurally connected to the variant of the third

00530 example (Figure 8). The reference numbers are

00531 also transferred here analogously and textually identical

00532 mend. 00533

00534 The further education measure exists according to the subject

00535 of FIGS. 10 and 11 in that the holding bead 9

00536 of the bottle neck 3 overlapping walls

00537 extension 30 slightly symmetrical

00538 is. 00539

00540 The opening angle is labeled Beta and is

00541 approx. Three degrees to a y-y to the central longitudinal axis

00542 find parallels. This facilitates the pin assignment.

00543 In addition, the inner edge of the wall extension could

00544 30 but also beveled, as shown in FIG.

00545 is visible. 00546

00547 A further training consists of

00548 that the jacket wall of the wall extension 30 in the area

00549 has a free ring end 37. Latter

00550 extends to reinforce the wall on the outside

00551 of the wall extension 30 and sets right on the bottle

00552 sided ring edge 33 of the disc 6. The ring-

00553 bead 37 takes a domed, seen in cross section

00554 history. A second annular bead 38 extends in the

00555 area of the other, upper end of the wall extension

00556 zes 30, also on the jacket wall of this

00557 lying down. Both ring beads 37, 38 are the same 00558 height. Because of the axial spacing, they

00559 which between them a peripheral ring trench 39

00560 available alternative space in the clamping

00561 assignment. 00562

00563 As is clear from FIG. 11, the upper,

00564 second ring bead 38 in the basic position slightly over the

00565 top 17 of the Duchstech seal D or the

00566 disc 6 in front. He runs over a diagonally inward

00567 directs sloping shoulder 40 into said top

00568 17 a. The corresponding wedging happens in

00569 upper area of the front edge 10 of the bottle neck 3. 00570

00571 When the crimp ring 5 is drawn on, the excessive one

00572 Edge section pressed down. That yields a bottle

00573 pressure component acting on the neck on the wall

00574 continued 30. 00575

00576 The equally high ring beads 37.38 favor the

00577 positive hold of the by pre-assembly

00578 plug-in crimp ring 5. Ring 5 and washer

00579 6 the encapsulation

00580 feed position. 00581

00582 When plug-in assignment prevents the thickening

00583 bead 37 a rolling up the free end

00584 of the wall extension 30. 00585

00586 When the crimp ring 5 is assigned, the result is about

00587 the bead 37 a well-sealing pressure just this

00588 end against the lateral surface of the bottle neck 3. 00589

00590 All disclosed features are essential to the invention. In

00591 the disclosure of the application is hereby also the

00592 disclosure content of the associated / attached priori 00593 full documents (copy of pre-registration)

00594 was included, also for the purpose of characteristics of this

00595 documents in claims of the present application with

00596 record.
