Description

I 0 1 D D T 2 PATENTS FORM 3 PATENTS AND DESIGNS ORDINANCE CLOSURE FOR CONTAINER German company do hereby declare the nature of this invention and in what manner the same is to be to be particularly described and ascertained in and by the following The invention concerns a closure of plastics for the inlet and outlet openings of cans and bottles made of several parts consisting of an annular collar adapted to slip onto the opening neck of the container and lodged with a groove behind an annular rib of the having saw on the outside of which collar a hinged lid is connected by means of a the hinged lid being lodged on annular collar in the condition and sealing the mouth of the In these closures the possibility of a sure repeated closure of the opening after partially removing contets of container is it is difficult to provide a safeguard for suoh closures against the unauthorized removal of the contents of container during transport from the dealer to custome o during which removal must be The known safety means consisted either of additionally attached sealing caps lead sealin or of welds which made the original To carry out the working steps required additional machinery and longer manufacturing time are It is the objec o the present invention to make a closure with safet of one which olosure be directly onto the container opening as a complete original This is attained according to the invention in that on side of the lid lying opposite the and a second band connected to a sealing ring is band constitutes seal of the lid slipped onto the opening the sealing after a swinging movement around has been inserted from below with corresponding catch means into the free opening of the annular The attached parts of suoh a are eonneeted to each other the described manner to a looked closure unit end assembled in the olosure machine for immediate This extremely simple and safe sealing possibility is practically through formation of the sealing arrangement of namely the annular collar and sealing whic are assembled together into a closed detachable unit and oan be locked against each I order to facilitat the assembl of the closure onto the neck openin with simultaneous centralization during the closing prooess and in order to achieve an additional bracing of the sealing ring against the annular wherein also an almost smooth transition of the outer contour of the into the circumferenoe of the neok opening must be so that there is no possible rim with the aid of whioh the on closure may be pried there is suggested in a further embodiment of the that the engaged inner surface of the sealing ring is tightly applied against the conical supporting surface of the neck opening adjacent the upper annular rib in attached condition of the olosure wherein the annular surface of the neok the supporting surface is flush with the outer of the sealing order to be able to remove the sealing band without the use of the transition of the sealing band the lid rim is tapered into a narrow breaking wherein tongues for grasping project radiall outwardly from the rim at both sides of the breaking The grasping tongues safeguard herein the Weakest part of the hinge band from mechanical for example during transport o the full containers or in the olosure arrangement An of the invention is shown by wa of example in the in 1 is an enlarged embodiment of a closure slipped onto the neck of a container partially in Pigo 2 is a side view of a in opened wherein the swinging movements assembly of the closure are indicated in 3 is a view of As oan be seen most clearly from and the container consists of the attached annular collar lid 1 safety ring All parts are connected with each other through the hinge band 4 and sealing band wherein hinge band 4 joins the lid 1 with th annular and the sealing banft lying opposite hinge band joins the lid 1 with the sealing On inner sur of the lid are arranged the usual clamping and sealing with the lid is slipped onto annular oollar 2 is ixed the assembly onto the neok 8 of a the lid 1 swung around the hinge band 4 and is clamped onto annular collar 2 as can be seen from lines of Then the safety ring 3 is swung around sealing band 5 and is set into the annula collar whereby conical portion is lodged in a corresponding opposing portion the annular collar Thus all parts are looked against each other and constitut a closed In the slipped condition the annular oollar 2 is lodged behind an annular 10 of the neck having a saw Thereby the eonioally engaged inner surface of the safety ring 3 lies tightly against the supporting insufficientOCRQuality
