Definitions

  • the c has a roof and 2 depending skirt constricted into cha 712321 1 nels at the levels of the shoulders.
  • the upper constric- 7209622 tion is of smaller dimension axially of the neck, than the spout and thus forms or defines an annular space facilitating insertion of a cutting blade to sever the roof from the skirt.
  • the upper constriction also acts to hold a sealing pad against the roof.
  • the lower constriction engages the second shoulder and retains the cap in place.
  • the skirt terminates below the second shoulder in contact with the neck.
  • the skirt has a thickness about the same BACKGROUND OF THE INVENTION
  • This invention relates to easy-opening, tamper-proof caps for receptacles such as bottles having a smooth neck, that is, one without threads, catches or the like.
  • Caps of the general type involved having a top or roof and a skirt integral with and depending from the periphery of the roof, are known.
  • Such caps may be made of a soft deformable material such as sheet aluminum, alloys of lead and tin, syntheticplastics, etc., and are used to initially obturate the pouring opening of the bottle, as well as stopping the same after opening, as when a portion only, of the contents is initially poured.
  • the caps envelope both the stopper or seal of the pouring opening and a greater or lesser portion of the neck of the bottle.
  • the skirt portion which extends down about the neck of the bottle has a plurality of perforatio'ns along a circumferential line and which form a weakened zone along which the cap may be severed or broken as a preliminary to opening of the bottle.
  • Caps of the type involved should be proof against fraudulent opening as in those cases where it is fraudulently intended to re-fill the bottle or to re-use the stamps.
  • unauthorized re use can sometimes be effected by deformation of the cap material and removing the cap without damage so that it may be subsequently and fraudulently reused.
  • the present invention has as a major purpose the provision of a cap and the combination thereof with a bottle neck, which is tamper-proof because it cannot be removed without damage such as will render the cap incapable of reuse. It is also an object to provide a cap of the type mentioned, which is easily initially emplaced, easy and simple to remove in opening of the bottle, and which can be manufactured at a price competitive with presently-known or prior art devices. Generally speaking, the present inventive cylindrical cap does not differ greatly in appearance from those which are secured in place by screw threads, and which must be made of heavier gage material or metal.
  • the inventive cap has interiorly, in contact with its top or roof forming the pouring spout obturation, a fluid-tight sealing capsule or gasket of cork or centrias that of the roof and is formed immediately below with an interiorIy-protruding circular channel located between an upper zone of the bottle neck of smaller diameter, and an integral enlargement thereof.
  • the channel has an internal minimum diameter equal to the external diameter of the top portion or pouring spout of the bottle neck.
  • the bottle neck and interior surfaces of the cap are smooth, that is, without threads, catches, etc.
  • the over-all internal height or dimension axially of the neck, of the aforesaid upper zone is about 6 mm.
  • the upper part of the skirt forms a constricted waist the upper and lower circumferential portions of which are in contact with the neck of the bottle, while its central or intermediate portion forms a bridge which is radially spaced from and out of contact with the neck and thus forms an annular or ring-like space between the pouring spout and the enlargement.
  • contact of the upper part of the waist with the spout of the bottle is effected by a plain circular groove which in addition to its space-forming role, also acts to maintain the sealing pad or gasket in fluid-tight engagement with the roof of the cap.
  • To open the bottle the cap is cut circumferentially of the neck, at the level of the aforesaid bridge which, being spaced from the bottle neck, facilitates the entrance of a cutting blade or tool, and acts to guide it in a circumferential path.
  • the central or bridge portion of the waist has a plurality of circular openings therethrough, spaced peripherally about the skirt, each having its edges directed internally.
  • the openings are located at a level where the wall of the channel is outwardly directed away from and out of contact with the pouring spout.
  • those openings are omitted over a small peripheral extent of the skirt, to thus provide a hinge for the roof and its sealing pad, thus retaining them connected with the skirt for re-use and re-sealing.
  • the construction just described defines an essentially circular line of severance and acts to facilitate opening of the bottle by making it easy to insert a thin knife blade or similar utility and guiding it in the desired path. While the roof and seal may be entirely thus severed and removed, it is preferable to leave a hinge portion as previously described.
  • FIG. 1 shows the profile in longitudinal axial section
  • FIG. 2 is a view partly in section and otherwise in elevation, of a cap prior to emplacement over the neck of the bottle and subsequent deformation;
  • FIG. 3 is a longitudinal axial section to an enlarged scale, of a cap after it has been emplaced over the bottle neck and deformed into connection therewith;
  • FIG. 4 is an axial section showing the cap after opening and with the top hinged back for pouring
  • FIG. 5 is an elevation of the cap showing the openings forming a weakened line of severance
  • FIG. 6 is an elevation of a modification wherein a weakened line of severance is formed or defined by aseries of sequential slots;
  • FIG. 7 is a view partly in section, to a scale enlarged over FIG. 6, the sectional portion being in a plane identified by line VII VII, FIG. 6;
  • FIG. 8 is a portion of the cap of FIG. 6 in section, in a plane indicated by line VIIIVIII, FIG. 6.
  • the bottle neck with which the novel cap is used is formed with a circular top 1 surmounting a cylindrical pouring spout 2.
  • spout 2 is an enlargement or band 3 defining first and second, upwardlyand downwardly-facing annular shoulders 11 and 4, respectively, FIG. 1.
  • shoulder 4 the neck 5 extends smoothly downwardly and radially outwardly. It is noted that the diameter of the enlargement is materially greater than that of the spout.
  • the cap is formed with a top or roof 6, FIG. 2, and an integral skirt 7 depending therefrom.
  • a circular constricted groove or channel 8 is formed in the upper part of the skirt contiguous to its juncture with the periphcry of the top and thus in addition to its other functions, acts to to secure sealing pad 9 in place.
  • the pad or gasket is relatively thin.
  • the diameter of that portion of the cap below channel 8 and overlying'enlargement 3 is fitted to have slight frictional contact therewith so that rotation of the cap relatively to the bottle neck is restrained.
  • the cap may be made of material such as sheet aluminum having a thickness of 0.2 to 0.3 mm. and which is ductile and readily deformable in manufacture.
  • the channel 8 is formed in such a way that its minimum internal diameter as indicated at 10, contacts spout 2.
  • the axial dimension of the channel is, as shown, less than the corresponding dimension of the spout so that there is left an appreciable annular space 12 just above shoulder 11, wherein the surface of the skirt is radially spaced from the spout.
  • bridge 14 may be cut or severed along a circular line, using a suitable blade or tool such as a knife. If desired, the bridge is formed over a limited peripheral distance, so that it seats fully within and against spout 2 and shoulder 11 to thus form a hinge portion as indicated at 15,. FIG. 3. Thus this limited portion of the cap is normally not severed but remains to form a hinge connection, FIG. 4, pivotally attaching the top of the opened cap to its skirt.
  • the location of the hinge 15 is indicated and identifiable by means of two circumferentially-spaced openings 14a located at the respective termini of the hinge. The openings 14a perform two additional functions.
  • Skirt 7, FIG. 3 is deformed inwardly to form a' constriction at 16, beneath enlargement 3 and in contact with shoulder 4, and thence extends downwardly to make circular rim contact at 17 with the base portion stamp extending over and across, the stamp being cut and thus rendered incapable of reuse by the severance and opening, thus positively preventing further or fraudulent use.
  • the material used for fabrication of the cap is more rigid than in ordinary caps so that its tamper-proof feature is thereby enhanced. It is rendered impossible to insert a tool between the neck and the skirt at contact line 17 and thence under constriction 16, without tearing or cutting the skirt.
  • the cut portion of bridge 14 skirt is composed of a central circular channel 26 in.
  • openings 27 which are formed a number of openings 27 separated by bridge portions 28.
  • the circumferential lengths of the openings and bridge portions are substantially equal. But if desired, two of the openings may be separated by a longer bridge 29 to thus form a part hingedly connecting the upper part 30 of the cap to its lower part 31.
  • Openings 27, FIGS. 7 and 8 are positioned in the circular channel 26 of the waist portion of the skirt, between the cirular lines of contact 32 and 33, respectively, between the cap and the neck of the bottle.
  • the two lips 27a, FIG. 8, formed in puncturing each of the openings, are directed inwardly and thus leave the external surface of the skirt smooth and devoid of sharp or cutting edges.
  • a bladed opener or a knife of conventional form is used to cut through and along the bridge portions 28, leaving theportion 29 intact, if present. It is then possible to hinge open the upper part 30 of the cap, which remains connected to the lower part 31 by reason of hinge means 29, to
  • the openings 27 play a part analogous to the openings 14a of FIG. 5, including that of inicating where the line of cut should terminate at the ends of portion 29.
  • a cap having a roof and a skirt depending therefrom, said skirt being cicularly constricted immediately below the roof to form a channel of minimum diameter to contact the spout, the axial dimension of the channel being less than the corresponding dimension of the spout tothus define an annular free space between the spout and first shoulder on the one hand, and the skirt on the other hand, said space facilitating severance of the skirt at the level of the annular space.
  • cap of claim 1 said cap being in one piece,.of a deformable material having a thickness of about 0.3 mm and total axial dimension between the interior surface of the roof and the minimum circular line of said constriction, of about 6 mm.
  • the cap of claim 8 said material being selected from the group aluminum, alloys of lead and tin, and synthetic plastic.
  • cap of claim 5 there being a plurality of cicumferentially-spaced openings through the skirt at the level of, and in communication with said annular space, each contiguous pair of openings being separated by an unpierced bridge portion of the skirt.
  • a cap of deformable material comprising a roof disposed over and obturating the pouring opening of said spout, and an integral skirt depending from said roof and extending over said spout, enlargement and upper neck portion, said cap being circularly constricted immediately below said roof to form a channel having circular line contact with the spout at the upper end thereof, said channel having a dimension axially of the bottle less than that of said spout, to thus form an annular space between said line of contact and said first shoulder, said skirtfitting smoothly over and about said enlargement, said annular space facilitating entry of a cutting tool to sever the skirt therealong.
