Description

BOTTLE CLOSURE BEING A SINGLE PIECE CAPSULE MOULD FROM PL AST 08 difficulties which occur in fitting plastic caps on glass which contain aerated liquids or onto bottles wherein pressure occurs and where pressurized gas or air are presen on top of a are well There are known such which an ior which is destined to hold the eap on the but this not always sufficient for resisting the gas pressure which is present in the interior of the bottle an which can cause spontaneous opening of the In the said has been resloved by combining plastic caps which an interior sleeve with outer such as known under the general denomination for The present to a novel type of one cap of plastic for the opening of which it is no necessary to use an opene and which spite of this can resist internal and elevated the said eap having its interior a tightening sleeve and provided with an outer holding ring integral the characterised thereby that a sheath within the surrounding the top of the neck of the bottle has portions which are radially of smaller thickness than the major part of said possible reducing the thickness to and further thereby that it is the general shape of the well known metal caps of the crown grasping ring is integral with the cap itself at the lowermost portion and along about of its and its opposite portion at least by one small and weak connecting part which can easily be At its uppermost part the cap may be provided with a mark indicating the point where the said weak connecting part is to be In a further preferred embodiment of the the top wall of the cap is concave at its outside so as to prevent a blowing up during According to yet another part of the outer wall of the cap is roughened for a purpose to In a specific form of the in vicinity of the said mark the said holding ring is provided with an outwardly extending said nose being positioned diametrically opposite portion where the said ring is moulded integrally with the eap According to further embodiments of the invention the said internal sheath may be of a or more With the new bottle closure it is possible to reclose a bottle after part of contents had been but it is always recognizable that the bottle had previously been It should understood that the main idea of reinforcin the ea b a rin which extends around so as to obtain a bottle closure according to the present The said and further features of the invention will become clear ferns the following detailed description which has reference to the annexed In the drawings 1 ia a perspective view of a cap according to the invention before removal from a 2 a perspective view of the same bottle closure during removal from a 3 is an elevational sectional view on lines of showin eehematically the use of a bottle opener on such is a plan view seen from above the cap is a plan view from below of a slightly varied construction of a cap according to the 6 is a plan view of yet another practical embodiment of the 7 is a perspective view of a slightly varied form of the cap according to the invention and intended to be provided with an excise 8 is an elevational section of the cap shon in the section being through the said excise is a perspective view seen from below of a cap having an internal tightening sheath of 12 is an exterior view of the same cap in a slightly different in 1 comprises a holding or grasping ring 1 which is along a portion of its periphery starting f om two one of which is visible at 2 in 1 with a covering cap 3 moulded in one piece and comprising an tightening sleeve as shown in cap 3 comprises at a diametrically opposite the point where it is unified with the ring a mark 5 signifying the point where thering 1 is to be pushed upwardly order to remove the cap from the At this point there are provided also ridges and grooves which make the surface of the cap so permitting the lication of the thumb 7 a person opening the as shewn in As already stated the mark 5 could also be provided thereby that the ring 1 is made with a radially extending extension or nose which serves disattaching the ring in relation the In it is seen that the cap 3 provided in its center with a depression 8 which on one hand as a place for applying thereto the index finger of a person which latter introduces the holding ring the 2 is that the simultaneous action of the fingers 7 and 9 and the ring 1 permits the removal of the cap thereby that the assembly of ring 1 and that portion of the cap 3 is integral with the ring is pulled in the direction of the thumb Furtheron it will be shown that during the said operation the cap is submitted to certain stresses which bring about a bending of small curvature at the level of certain weakened portions of said and it is shown that the lowermost portion of the ring 1 is provided with a groove 10 which permits the opening by means of a bottle openerv 10a of the conventional A detail of the inner tightening sheath of the cap is shown in the sheath being indicated by the numeral inner sheath is composed of portions which have a maximal radial such as portions 12 shown in and portions which of a minimal thickness such as portions 12a shown in the same weakenings are provided in the outermost wall of the cap at points 13 where the said eheath to permit the while being eubmitted to the action of the finger prior to full disengagement the to It should bo remarked that the sheath 11 moulded in one cap and connected thereto by two small ribs which are easily broken and which are seen at 15 in and which are positioned in the of construction Just described at the level of two o the weakened portions 13 but they also be set off in to these weakened The fact that a bottle had been opened can be detected on the one hand thereby that ribs 15 have been broken but even since after of the ring around the cap Breakage of the ribs 15 is no longer an opening o the bottle can be by fissures along the vertical wall at the outside of cap To be these fissures not shown in the In the constructional forms shown and 6 the connection between the ring 1 and the cap is the same as in construction of but the is constituted in according to two halves 11a which are separated from one another b empty portions 16 which extend through the thickness of the outer wall of the ca but do not reach to the gap 17 which separates ring the cap removal of cap from the bottle fissures are produced the outer wall of the cap at the level of the empty portions which fissures remain visible even a ter resettin of the ca on the constructional form of 6 the sheath is constituted by an element which extends over an angular sector of and two 11c which over sections in the of Xt can easily be that whatever means are employed orremoval of the be the of the 1 or be the use of a opener as shown at 10a it is advantageous to have the sheath not exactly at the level of that part of the cap onto which the traction or pressure is in way that the become free of the by their inherent In the same at the level o the weakened parts 18 in 6 which are provided in the most wall of the a bend is provoked along a line is perpendicular to the plane of symmetry of the cap and is positioned at the level of the intervals between elemen lib and element This bending stress at level o the weakened points in fissures which visible even a ter replacing the ring 1 into To be the constructional form of which comprises a sheath of a considerable radial thickness which but interrupted at two is adapted and destined for bottles in interbr of which there is a considerable gas the other of being sufficient for In order to facilitate grasping of the ring 1 by means of the index finger 9 there is shown in 1 and that the thickness of the ring is at la at the point which is opposite the connection of the ring the cap In the construction shown 7 and 8 the holding ring 1 is also provided with a part slightly different from the part la already This portion is opposite that point at which the ring is made Integral with the ca It is in shape so as the use of that second part for carryin a seal as is required in the ease of certain goods are subject to excise In this there is or welded onto the uppermost portion of the cap 3 onto the top of the second portion a of cardboard or the like material such as onto which a metal seal
