CLASS 1NTERNATIONALSVENSK A61 j30g: 3 PATENT AND REGISTRATION AGENCY Ans. 4983/1958 on 23/5 1958To this a drawing El B JORGENgEN, VIBY J. DENMARK Proppartat, through-pocket lid for containers Priority requested from 24 May 1957 (Denmark) For 'closing of containers, fla: shoes or other glass vessels, as used, in laboratories, in hospitals and the like, the stalls for receiving liquids of the Tnest .different kinds, which are to be kept sterile and • later used for injection, infusion or other duck, amal, for which the andamal liquid. the edge to use a tightly fitting lid of, elastic material, suitably soft material .of natural or synthetic rubber, which lid for removing a certain part of the contents can be pierced Died a cannula but as., the air cannula, after completion of removal Re-pulls out of the lid, contracts and allows the tail of the cannula to reach the tail completely, so that the remaining water in a safe way can continue to be stored. sterile.

Eftersom lock av delta slag aro utsatta for ganska stora. tryckdifferenser, N. a. under sterilisering av de ifragavarande behallarna e. ci. i autoklaver, fasthalles locket vanligtvis vid behallarhalsen, meclelst en av metal]. :eller annat .stelt material tillverkad kapsel„ som omsluter halsen och som uppvisar en. kluge, vilken 'stracker sig in over kanten av locket och vars centrala del ar fri, ,sa att locket kan genomstickas innanfor kragen. Because lids of delta kind are prone to quite large. pressure differences, N. a. during sterilization of the containers in question e. ci. in autoclaves, the lid is usually attached to the container neck, usually one of metal]. : or other .stiff material made capsule „which encloses the neck and which has a. hatch, which extends over the edge of the lid and whose central part is free, so that the lid can be pierced inside the collar.

Under ,steriliseringen I autoklav kan uppsta. ett overtryck av en ,eller flera atmosfa..- rer i behallaren, varvid det ,elastiska locket kommer att hukta ut, vilket vid lock for behallarhalsar, vars invan.diga diameter ar forhallandevis 'stor, t. .ex. icke understigande 25 —30 mm, latt kan medfora, att locket lossnar fran halsen eller helt fjadrar ay. For att avhjalpa denna nackdel dr ,det kant att for- Dupl. kl. 64 a: 43/01 starka kaps,eln med hjalp av en under dennas krage anbragt platta av stelt material, isom tacker den centrala delen av .sjblva lockets oversid,a ,och som dr fOrsed,d med. hal eller oppningar, genom vilka kanylen kan .stickas ned i locket. During, the sterilization in the autoclave may occur. an overpressure of one or more atmospheres in the container, whereby the elastic lid will crouch out, which in the case of lids for container necks, the internal diameter of which is relatively large, e.g. not less than 25-30 mm, which can easily cause the lid to come loose from the neck or completely spring up ay. To remedy this disadvantage dr, it edge to for- Dupl. at 64 a: 43/01 strong caps, eln with the aid of a plate of rigid material placed under its collar, which thanks the central part of the upper side of the lid, a, and which dr fOrsed, d with. hal or openings, through which the cannula can be inserted into the lid.

Vict nedtryckning air kanylen ii det elastiska locket bojes della nigot naddt och genomsticksstallet tryckes hurt Iran tackplattan, varigenom luft intranger mellan denna och lockets oversida. Derma luft press as miss cr11gem Ater ut, nr kanylen drages tillbaka, men erfarenheten har visat, aft !skiljeytorna meilan locket och plattan ofta inficieras, ,och det bildas, bakterie- eller mikrobkolonier mellan dessa. Detta torde hero pa forekontsten av intrangd luft mean .skiljeytorna, I. ex. .sasom nanints har ovan. When depressed, the air cannula in the elastic lid is bent, bent and slightly pierced, and the piercing stall is pressed hard on the roof plate, whereby air penetrates between it and the upper side of the lid. Derma air pressure as miss cr11gem Ater out when the cannula is withdrawn, but experience has shown that the separating surfaces between the lid and the plate are often infected and bacterial or microbial colonies are formed between them. This should be taken into account in the occurrence of intrusive air mean the separating surfaces, i.e. .as nanints have above.

Uppfinningen avser ett sadant lock for .ovannamnda ,andamal, .som bestar av en av elastiskt, genomstickbart material, t. ex. mjuk kautschuk och/eller plast, franastalld .skiva, vars for intryckning i behallarhalsen avsedda parti avslutas med: en avsats, for taftslutande anliggning mot overkanten av behallarhalsen. Andamalet riled uppfinningen är att avhialpa ovannamnda nackdel, och .detta uppnas ddrigenom, att i .sjalva lockskivan som integrerande del ingar en armering am stelt material, t. ex. metall, .som Or sa afford, att den. tillater en genomstickning ay skivan medelst en kanyl. The invention relates to such a lid for the above-mentioned, andamal, which consists of an elastic, pierceable material, e.g. soft rubber and / or plastic, made of disc, the part of which is intended to be pressed into the container neck and ends with: a ledge, for abutment against the upper edge of the container neck. The object of the invention is to remedy the above-mentioned disadvantage, and this is achieved by the fact that in the cover plate itself as an integrating part a reinforcement of rigid material, e.g. metal, .as Or said afford, that it. allows a piercing of the disc by means of a cannula.

Genom denna annexing, som kan vara sammangjuten eller hopvulkaniserad Tned skivan, hindras en uthuktning av .skivan bade vid 'forekommande overtryck I behillaren och vid nedtryckning genom skivan ay ka- 2— — nylen eller mid uttagning ay denna. Skivan. och arineringen bilda en oskiljbar ,enhet utan skiljeytor, mellan vilka bakterier ,eller dammrnikrober kunna intran.ga och bilda kolonier, som kunna fororsaka inficiering am behallarens innehall. This annexing, which may be co-molded or vulcanized on the disc, prevents the disc from bulging out both in the event of overpressure in the container and in the case of depression through the disc in the cannula or in the removal thereof. The disc. and the arination form an inseparable unit without dividing surfaces, between which bacteria or dust microbes can intrude and form colonies, which can cause infection in the contents of the container.

A pair of embodiments of a lid according to the invention are damaged in the accompanying drawing, as shown in Fig. 1. , a section through the one embodiment, Fig. 2, the same embodiment, seen from above, and Fig. 3 a section through. a lid .according to the second embodiment. • -With; 1 denotes a flat cover plate, which is challenged by a soft, easily pierceable material, suitably soft rubber. On the upper side of the disc 1, a reinforcement is fixed vulcanized, which consists of a plate 2 with openings 6, in which the disc 1 is easily accessible for piercing. Plate 2 SHOWS a curved edge 5 at the circumference of the disc.

Den i fig. 3 visade utf6ring,sform,en skiljer sig Iran utforingsformen .enligt fig. 1 och 2 .endast darigenom, att armeringen I stallet for am plattan 2, 3, utgores av en lampligen metallisk tradmay 7, ,sorn har .sa. .stor maskvidd, att en kanyl kan passera genom maskorna, vilka kunna mara markera:de pa oversidan ay skivan 1. The embodiment shown in Fig. 3 differs from the embodiment according to Figs. 1 and 2 only in that the reinforcement instead of the plate 2, 3, consists of a suitably metallic tradmay 7, which has the same shape. . large mesh size, that a cannula can pass through the meshes, which can mark: those on the upper side of the disc 1.

Darvid Iran svamel frigoras frin kautschuken och fororena vatskan i behallaren. For ayhjalpande av denim nackdel är del kant att tillverka icke armerade lock am bade kautschuk och am en plast, t. ex. polyvinylklorid, soin icke paverkas am yatskeangorna, maryid den nedre &len ay lockskivan utgiires av plasten, medan den owe delen am :skivan bestar am rnjuk kautschuk, som efter uttagning am en del av behallarens innehall lampar sig bast for fullstandig tillslutning am det hl, Isom astadkommes mid kanylens instickande I locket. Det am de hada namnda materialen tillverkade locket framstalles vanligtmis genom f5rbindande av de tva ,delama med hjalp .av ett bindemedel. Pet har ,emellertid visat sig vara relativt .svart att astadkomma ett bindemedel, som ingar en .sâ intim forbindelse med de mot varandra vanda ytoma pa de lva .delarna, att Corbin-deism. alltid Mir hallbar. Containers of various types are often used for receiving ammunition, which during sterilization in an autoclave develop angles which attack the rubber in lids, in which the entire lid disc 1 with associated collar plug, pp, is protruded "of delta material. In this case Iran sulfur is released from the rubber and To help with the denim disadvantage, part of the edge is to make non-reinforced lids with both rubber and a plastic, such as polyvinyl chloride, which are not affected by the yat vapors, maryid the lower part of the lid is made of the plastic, while the owe part am: the disc consists of rnjuk rubber, which after removal am a part of the contents of the container lights itself bast for complete closure am the hl, Isom is accomplished by inserting the cannula into the lid.The lid made of the said materials is usually made by connecting The two parts, with the aid of a binder, have, however, been found to be relatively difficult to produce a binder which, in ngar has such an intimate connection with the opposing surfaces of the lower parts, that Corbin deism. always Mir hallbar.

Denna nackdel avhj alpes med locket enligt foreliggande uppfinning, mid vilket den ovre delen, am .sjalva lockskivan är utford ay kautschuk medan skivans nedre del Or utford av plast, i det att del ,enligt uppfinningen anellan de tva delarnas mot varan.dra vand:a; ytor Or ,anbragt alminstone ,ett rnellanlagg ay fibrer, foretradesvis i form av vim. Mellanlaggets fibrer kunna vara av ,animaliskt eller vegetabiliskt ursprung eller besta av glasfibrer eller plastfibrer am vilket .som heist lampligt slag. This disadvantage is remedied by the lid according to the present invention, in which the upper part, the lid itself, is challenged by rubber while the lower part of the disc is made of plastic, in that according to the invention part of the two parts is against each other: a; surfaces Or, arranged at least, a rnell plant of fibers, preferably in the form of vim. The fibers of the intermediate layer may be of animal or vegetable origin or consist of glass fibers or plastic fibers which are of a suitable type.

'Gen= ,sammanbindning av ,delarna me deist eft mjukgjort bindemedel upptages detta i mellanlagget, som darvid bides yid de hada 3rtorna och ,erfarenhetsmassigt tillfor,sakrar en god: forbindelse mellan dessa. 'Gene =, bonding of, the parts with deist eft softened binder, this is taken up in the intermediate layer, which is thereby bided yid the hada 3rtorna and, from experience, lacks a good: connection between these.

Vid lock av anfort slag, dar armeringen bestar ay tradvav, kan mellanlagget vikas om .denna och anbringas mellan isj alma lockskivans tva delar. In the case of lids of the type mentioned, where the reinforcement consists of wire mesh, the intermediate layer can be folded over.

En myeket tillforlitlig forbindelse mellan dessa delar kan vidare astadkommas darigenom, att mellanlagget, .eventuellt tillsammans med tradvavsarmeringen, anbringas i bottnen av den 'form, i Milken den ovre delen ay kautschuk skall vulkaniseras, varpa den oyulkaniserade kautschuken anbringas p0 mellanlagget pa ,sa. salt, att delta hopvulkaniseras med kautschukdelen. Denna del anbringas Over den i en annan form inforda plasten for framstallning ay den nedre delen mad mellanlagget main mot plasten, vaTpa denna uppvarmes och mjukgores och den ovre delen_ pressas ned mot plasten, som darvid tranger in I mellanlagget och sammanbinder de tva. delarna till en oskiljbart sammanhangande enhet. A very reliable connection between these parts can furthermore be achieved by placing the intermediate layer, possibly together with the wire rope reinforcement, in the bottom of the mold in which the upper part of the rubber is to be vulcanized, whereupon the unulcanised rubber is applied to the intermediate layer. salt, to participate is vulcanized with the rubber part. This part is applied over the plastic introduced into another form for production in the lower part of the intermediate layer main against the plastic, which is heated and softened and the upper part is pressed down against the plastic, which thereby penetrates into the intermediate layer and connects the two. the parts of an inseparably coherent unit.
