Description

Opfindelsen angår en beholder af den i kravets indledning angivne art.The invention relates to a container of the kind specified in the preamble of the claim.

148406 Sådanne beholdere med sikkerhedslukker tjener til at vanskeliggøre lukkets aftagning i tilstrækkelig grad til, 5 at børn og andre, som er uvidende om de farer, beholderens indhold kan frembyde, ikke kan åbne beholderen, der f.eks. kan være en medicin- eller pilleflaske, uden at åbningen dog bliver så vanskelig, at den volder problemer for den kvalificerede bruger.Such closure containers serve to make the closure of the closure sufficiently difficult to prevent children and others who are unaware of the hazards that the contents of the container may present cannot open the container, e.g. can be a medicine or pill bottle without the opening being so difficult as to cause problems for the qualified user.

10 Opfindelsen har til formål at forøge sikkerheden mod uautoriseret åbning af en beholder af den omhandlede art.The invention has for its object to increase the security against unauthorized opening of a container of the kind in question.

Dette formål opnås ved, at beholderen er udformet som angivet i kravets kendetegnende del, idet lukkehætten ved denne konstruktion skal drejes en lille vinkel i påsætningΞΙ 5 retningen, inden spærreorganet kan trykkes ind til ophævelse af spærringen.This object is achieved by the container being designed as indicated in the characterizing part of the claim, the closure cap of this structure having to be turned a small angle in the application direction, before the locking means can be pressed in to release the locking device.

Opfindelsen skal forklares nærmere i det følgende under henvisning til tegningen, hvor fig. 1 i perspektivisk afbildning viser et sikkerhedslukke, 20 som opfindelsen kan finde anvendelse på, og fig. 2 i snit viser en detalje ved en tilsvarende beholder udformet ifølge opfindelsen.The invention will be explained in greater detail below with reference to the drawing, in which 1 is a perspective view of a security closure to which the invention may apply; and FIG. 2 is a sectional view of a detail of a corresponding container designed according to the invention.

På tegningen er 30 den øverste del af en flaske, fortrinsvis af glas, på hvis hals 31 er fast anbragt en krave 32 25 af et stærkt, elastisk materiale som f.eks. polypropylen, 143406 2 polystyren eller nylon. Kraven 32 er udformet med et udvendigt gevind 33 og med en endeflange 43, som begrænser en midteråbning 44. Kraven 32 er endvidere udformet med en langs underkanten forløbende vulst 36, der er op-5 slidset som vist ved 37, og hvis ene ved opslidsningen fremkomne endestykke 38 er adskilt fra den øvrige del af lukkehætten og danner et elastisk eftergiveligt spærreorgan, som i sin viste upåvirkede stilling rager radialt uden for den fastsiddende del af vulsten. Kraven 32 kan 10 være fremstillet ved sprøjtestøbning.In the drawing, 30 is the upper portion of a bottle, preferably of glass, on whose neck 31 is fixedly mounted a collar 32 25 of a strong, elastic material such as e.g. polypropylene, polystyrene or nylon. The collar 32 is formed with an external thread 33 and with an end flange 43 which limits a central opening 44. The collar 32 is further formed with a bead 36 extending along the bottom edge, which is slit as shown at 37, and each at the slit The resulting end piece 38 is separated from the other portion of the closure cap and forms an elastic resilient locking member which, in its unaffected position, extends radially outside the fixed portion of the bead. The collar 32 may be made by injection molding.

Den til kraven 32 hørende lukkehætte 34 har et skørt 45 med et indvendigt gevind 35, og en endevæg 46. Lukkehætten 34 har desuden ved sin nedre kant en muffedel 39, der har lidt større diameter end den øvrige del af lukkehætten og tje-15 ner til optagelse af vulsten 36 på kraven 32. I indersiden af muffedelen 39 er udformet en langs en del af muffedelens underkant forløbende, i hovedsagen kileformet udsparing 40, hvis stumpe endeflade 41 danner en til samarbejde med spærreorganet 38 på kraven 32 bestemte stopflade. Ud-20 sparingen 40 afgrænser et tyndvægget muffeområde 42, hvis beliggenhed kan være markeret på muffens yderside. Fig. 1 viser en kendt udformning af en sådan krave med tilhørende lukkehætte.The closure cap 34 of the collar 32 has a skirt 45 with an internal thread 35, and an end wall 46. The closure cap 34 additionally has at its lower edge a sleeve portion 39 which is slightly larger in diameter than the other portion of the closure cap and servings. for receiving the bead 36 on the collar 32. Inside the sleeve portion 39 is formed a groove 40 extending along a portion of the bottom of the sleeve portion, generally wedge-shaped recess 40, the obtuse end surface 41 of which forms a stop surface for cooperation with the locking means 38 on the collar 32. The recess 40 defines a thin-walled sleeve area 42, the location of which may be marked on the outside of the sleeve. FIG. 1 shows a known embodiment of such a collar with its closure cap.

Når hætten 34 skrues på kraven 32, bliver spærreorganet 38 25 trykket ind af muffedelen 39. Den kileformede udsparing 40 og spærreorganet 38 er fortrinsvis således beliggende i forhold til hinanden og til gevindene 33 og 35, at stopfladen 41 efter en kort drejning af lukkehætten fra lukke stillingen støder imod enden af spærreorganet 38, 30 som således spærrer for yderligere drejning. Denne spærring kan ophæves ved, at der med en finger trykkes på det tyndvæggede område 42 af muffen 39, idet dette område er tilstrækkeligt eftergiveligt til, at spærreorganet 38 derigennem kan trykkes så langt ind, at stopfladen 41 kan 35 passere forbi det. Lukkehætten kan herefter skrues af uden yderligere hindringer.When the cap 34 is screwed on the collar 32, the locking member 38 25 is pressed in by the sleeve member 39. The wedge-shaped recess 40 and the locking member 38 are preferably positioned relative to each other and to the threads 33 and 35 so that after a short rotation of the closing cap from the closing position abuts against the end of the locking means 38, 30 thus blocking further rotation. This lockout can be removed by pressing a finger on the thin-walled region 42 of the sleeve 39, this area being sufficiently resilient that the locking means 38 can thereby be pushed in so far that the stop surface 41 can pass past it. The closure cap can then be unscrewed without additional obstacles.
