[R:ALIbpal)Ttaoi3Iator Ver~fioptlon Ce1iffim. tm ror Published~doo:STL 1 BOTTLE CAP SAFETY SEAL DESCRIPTION 5 OBJECT OF THE INVENTION [0001] The present invention relates to a bottle cap safety seal of among the different seals intended for 10 bottle sealing purposes. [0002] This invention is characterised in a special construction of the seal, which incorporates rupture points in relation with the rim and others which facilitate the separation of the disc with respect to the skirt of the 15 seal, leaving an under-ring on the neck or not. [0003] It is characterised in a manner of securing which employs projecting teeth arranged with an equal distribution over the length of the inside of the lower cylindrical body of the seal. These teeth appear in plan 20 view with the rim straight and below have an oblique planar surface for the tapering which permits an adequate insertion. [0004] It is also characterised in a prolongation according to a plane of the tooth which provides an 25 adequate resistance to pressure on the upper step when the seal has been inserted on the body of the cap. BACKGROUND OF THE INVENTION [0005] Bottle cap safety seals have also extended their 30 field of application to bottles, it being sufficient to cite as example of the great number seals with these characteristics, those of the European patent with publication number EP0502379 and the Italian patent of invention no22272/87, both of Guala, S.p.A. and, like 35 practically the entirety of those known, with means for 2 rupture of the lower part of the skirt which separate an internal ring from the rest of the seal. [0006] Thus the seals are known which have a recess in the upper base, in form of an inverted "S" and with the 5 ends and the central area thereof prolonged with individual slots which reach the peripheral rim of the seal. [0007] It is only through these cuts in the upper base through which the brand name of the maker of the beverage is observed with supreme difficulty, a most undesirable 10 feature. [0008] The construction of the two tabs resulting from the aforementioned inverted "S" and the prolonged grooves thereof which, wen released, take the form of a bracket in which one end rim flange runs from the rupture area thereof 15 with respect to a lower ring of the skirt and the other flange starts in the base of the seal; and, its rim is rounded coinciding with the curvature of the inside of the "S". [0009] Hence, an additional difficulty with this type of 20 safety seal, indeed of greater significance, is that arising from the actual structure of the bracket which, When the user inserts a fingernail under the curved rim of the flange it runs the risk of being broken when prising the flange up making use of the same as a lever. 25 [0010] The securing of the seal on the body of the cap is usually implemented by means of a peripheral projection. It is sufficient to mention the Spanish patent of invention with publication number ES2153263 wherein is shown a pouring cap whose means of securing to the container 30 consists of a continuous step of triangular section, arranged peripherally and internally, and which permits the entrance of the cap over the neck of the bottle but impedes escape through resting against an edge of the container on the straight part of the triangular step. 35 [0011] The problem with this type of fastening lies in 3 that on insertion the truncated conical surface which facilitates the entrance of the edge of the internal body, it establishes a pressure over the whole perimeter. Each point of this step of triangular section has an opposing 5 point, and the only possibility of admitting the entrance of the projection with its smaller diameter with respect to the edge of the internal body is by stretching in a tangential direction of the cylindrical body on which is located the projection of triangular section. 10 [0012] It is also to be pointed out that the greatest stress occurs on the rim which defines the vertex of the triangle of its section where less resistance is encountered. [0013] A solution which permits sufficient deformation 15 so that the external body, in this case the seal, enters by passing over the smaller diameter which defines the rim of the triangular step consists in reducing the dimensions of the step. [0014] This solution permits an easier entrance of the 20 seal; however, the reduction in the dimensions of this projection also implies reducing the supporting surface after insertion, facilitating its removal when this is a safety element which has to guarantee the inviolability of the seal. 25 [0015] The present invention discloses a special design of the seal based on simplicity and quality of finish wherein are also included some securing teeth which permit easy entrance as well as a support of sufficient strength to prevent the removal and improper manipulation of the 30 covering cap. DESCRIPTION OF THE INVENTION [0016] The present invention relates to a cap safety seal, of among the different safety seals for caps of 35 bottles, usually for liqueurs.
4 [0017] This invention is characterised in a special construction of the seal, which incorporates in its upper base a broad disc with a completely free surface, which permits the brand name of the drink manufacturer to be 5 incorporated very easily. will redound in an improved amortisation and better ret [00183 This disc comes with a semicircular radial prolongation, in the form of and used as a tab which proves accessible through an opposing perforation which covers the 10 peripheral rim of that area of the seal as well as part of the flange immediately below the same. [0019] The tab includes rupture points, well removed from area of the tab, in order to facilitate the lifting of the same without affecting the fingernail of the user and 15 which join the latter with respect to the rim of the base. [0020] It likewise has other unions, in the form of breakable straps, which define a weakened line, at least two being located on the rim, which facilitate the quick separation of the disc with respect to the rest of the 20 skirt of the seal. [0021] These breakable straps can be multiplied and prolong the weakened line until almost reaching the lower area of the skirt leaving an under-ring on the neck or else reach the rim of the same. 25 [0022] With respect to the means for securing the seal, in the section on background of the invention, the drawback of using peripheral continuous projections was explained since they oblige high pressures for the insertion of the seal over the cap giving rise in turn to high tangential 30 stress and supports which are not always sufficient to guarantee inviolability. [0023] This drawback is overcome by incorporating occasional equally distributed supports, the projection of which on the interior establishes an adequate support on 35 the straight surface.
5 [0024] These occasional supports comprise by some teeth by way of internal projections on the lower cylindrical body of the safety seal. [0025] Each of these teeth is configured according to a 5 plan view with the rim projecting toward the interior in a straight section, as per a secant, thereby removing the presence of corners which establish possible support points potentially useable for removing the seal from the cap. [0026] The depth of the tooth depends on the width 10 thereof and on the radius of the seal since the projection in plan view is defined by a secant. [0027] The tooth has a planar and oblique lower surface, which establishes the taper which facilitates the entrance of the seal when it is inserted. 15 [0028] Instead of terminating the planar and oblique surface directly on the step, the projection is prolonged according to a second planar and vertical surface increasing the height and eliminating the presence of sharp rims of less strength. 20 [0029] It is on this planar section where the straight step appears, whereon is established the support for the edge of the body of the cap where the seal is fastened. [0030] Thus, each of the teeth is configured according to three planes, the lower one oblique in the form of a 25 taper, the central one vertical which extends the tooth in height, and the upper one horizontal which defines the support. [0031] Given that the supports are individual, one for each tooth, during insertion there is a certain deformation 30 of the cylindrical body of the seal where they are located. [0032] This deformation is in such a manner that the projections tend to push radially outwards, and the sections between projections tend to reduce their curvature through the tension in order to yield and permit insertion 35 of the seal.
6 [0033] In this way the deforming of the cylindrical body in some way approximates to a polygon wherein the teeth would be arranged in the vertices of said polygon. [0034] During this same insertion, after the teeth pass 5 over the edge on which they rest, said teeth enter the recess which houses them. [0035] The configuration of the cylindrical body resumes its original condition, prior to deformation, so the teeth establish an adequate support on the edge of the cap 10 preventing the escape thereof. DESCRIPTION OF THE DRAWINGS [0036] This descriptive specification is completed with a collection of drawings wherein by way of illustration and 15 not restrictively, the preferred embodiment of the invention has been represented. [0037] Figure 1 shows the upper base and the elevation of the safety seal of the preferred embodiment, viewed from 20 the front of the tab. [0038] Figure 2 shows a cross section of the seal when incorporated on the cap, the seal being highlighted by a thicker line. 25 [0039] Figure 3 shows the top and bottom plan and two profiles of an embodiment of the seal according to the invention showing the means of securing by teeth. 30 [0040] Figure 4 shows a detail of the teeth in plan view and profile, wherein the cylindrical section of the seal on which it is situated appears partially represented by way of reference. 35 PREFERRED EMBODIMENT OF THE INVENTION 7 [0041] In the light of the foregoing, the present invention relates to a bottle cap safety seal, of among the different cap safety seals, essentially characterised in that it incorporates on its upper base (1) a broad disc 5 (2), with tab (3) opposite a perforation (4) which is prolonged according to a channelled section which covers the peripheral rim (5) of the upper base (1) and part of the skirt (6). [0042] The tab (3) has some rupture points (7) removed 10 from the tab (3) and with, at least, two external weakened lines (9), for separation of the disc (2) from the rest of the skirt (6) of the seal. [0043] The surface of disc (2) is completely free, for the incorporation of makers' brand names. 15 [0044] The weakened lines (9) reach almost to the lower area of the skirt (6), leaving a lower ring (10) or else reach the rim thereof. [0045] Figure 3 shows an embodiment of the seal, in a shorter configuration than that shown in the embodiment 20 shown in the embodiment illustrated in figures 1 and 2, wherein are shown the teeth (8) or projections object of this improvement intended to establish support on an external peripheral recess of the cap. [0046] Figure 4 likewise shows a detail of one of the 25 teeth (8) in elevation and profile. [0047] The tooth (8) is delimited by three planes: " the oblique lower plane (8.1) which facilitates the entrance of the cap on insertion by establishing the sufficient degree of tapering for the projection; 30 0 the central vertical plane (8.2) which extends the tooth (8) in height and strength; " the horizontal upper plane (8.3) of support against the inside surface of the peripheral recess of the cap in order to prevent escape of the seal. 35 [0048] Given that the vertical plane constitutes a 8 secant in the plan view, it is possible to relate the width (a) of the tooth (8) with the depth (e) of the latter, the relation being of the form 5 e = r{l-q(l-a 2 /4r2)} where r is the inside radius of the cylindrical body where the tooth (8) is situated. [0049] In this way, for a determined width, a greater 10 depth is achieved of the step by increasing its width. [0050] This greater width in turn reduces the distance between teeth (8) and therefore increases the stiffness which prevents the deformation of the lower part of the cylindrical body of the seal at the time of insertion. 15 [0051] In the particular case of this preferred embodiment of the invention use has been made of eight equally distributed teeth (8). [0052] In the profile of tooth (8) shown in figure 4 the vertical prolongation (8.2) can be observed under the rim 20 which is established with the upper surface (8.3) where the support is produced with the upper face of the peripheral recess of the cap (this recess is not shown in this figure and adopts a profile opposite to that of the profile shown, that is, the profile which corresponds to the middle 25 section according to a vertical plane which runs through the axis of the seal. [0053] It is this vertical prolongation (8.2) which permits a response to the upper support by means of a compressive force and not compressive plus flexing as 30 occurs in the projections envisaged in the section on background of triangular section. [0054] This support offers greater strength while avoiding support points appearing (even being individual elements and not peripheral projections) from the lower 35 part which facilitate the withdrawal of the seal which 9 permit the improper manipulation of the cap. [0055] The essential nature of this invention is not altered through variation in the materials, form, size and arrangement of the component elements, described in a non 5 restrictive manner, which is sufficient for an expert to proceed to its reproduction.
