Definitions

• the present invention is intended to provide a non-refillable cap for bottles of liquors and the like that provide sensitive features of novelty and inventive activity.
• the cap not only offers features that prevent its direct refilling after opening the usual screw cap of the bottle, but also has characteristics that make it difficult to disassemble the cap with respect to the bottle to fill it with lower quality drinks.
• the aim of the present invention is to achieve an non-refillable cap of the generally known type consisting of an outer shell or tube cap, associated with the screw cap to the body, which is retained in the neck of the bottle and complemented with a piece called washer that is the one that is centered in the inner part of the hole of the neck of the bottle, and that externally in many cases is associated by protrusions and recesses with the body of the cap, which It is a source of complications and increased cost.
• the washer internally receives the valve that is of the single-type type, that is, it allows the liquid to exit at the moment when it has been removed by unscrewing the cap and does not allow the introduction of a new liquid, since it is arranged on a suitable seat of the washer, preventing the entry of liquid inside the bottle.
• the present invention is based on the constitution of a body for the cap that is coupled with a reinforced area of the washer simply by conical seat, that is, without the need for special fittings that significantly complicate the manufacture of the molds and that of the molds. own pieces.
• the body is retained inferiorly by the usual step in the neck of the bottle.
• the tube cover is retained in an anti-rotation function with respect to the body by making multiple groups of small incisive projections on vertical bridges connecting the lower flange of said body, so that when the tube cover is mounted on the body, said projections, preventing the rotation of one element with respect to the other.
• the lower edge of the body is simply straight without any need for retention with the outer tube cover.
• the essential improvement of constituting the lower part of the body of the cap has been introduced in multiple independent sectors by means of separation cuts or substantially longitudinal continuity solutions, giving rise to a series of independent wings that adapt each of them separately from the others with the lower edge of the neck.
• the number of sections may be variable as well as their specific dimensional characteristics.
• the longitudinal cuts or separations are the most practical from the manufacturing point of view, it is not excluded that said lateral separations between the different zones could take place in the form of oblique, curved cuts or other type.
• Figure 1 shows a partial longitudinal section of a non-refillable cap incorporating the present invention.
• Figures 2 and 3 are details of the area of engagement of the flange of the body with the neck of the bottle with and without windows, respectively.
• Figure 4 shows a side elevation view of the body of the non-refillable cap.
• Figure 5 shows a plan view of the body of Figure 4 itself.
• Figures 6 and 7 represent each section along the planes of the cut represented in Figure 5.
• Figure 8 shows a bottom view of the cap body itself.
• Figure 9 shows a complete section of a non-refillable cap body according to a variant.
• Figure 10 shows a side elevation view of the body of the non-refillable cap of Figure 8.
• Figure 11 shows a bottom view of the body of the non-refillable cap of Figures 9 and 10.
• Figure 12 shows a perspective view of the variant itself.
• the non-refillable stopper object of the present invention is intended for the non-refillable closure of a bottle whose neck -1- has a conventional structure, being covered externally by the tube cover -2- which in turn receives superiorly the overcap -3- whose unscrewing will release the open upper part of the body -4- provided with the upper outlet opening of the liquid contained in the bottle .
• An intermediate valve -5- sits on the flange -6- of the inner part of the washer -7-, which is coupled to the inner surface -8- of the neck -1- of the bottle and sits on the upper face of said neck. Below the valve -5- the washer -7- has a certain opening, for example, by means of crossed radial bridges -9-.
• the washer -7- has a reinforced structure -10-, especially in the part of the base whose outer wall -11- is conical and is intended to receive the also conical inner wall -12- of the opposite part of the body, achieving in its axial introduction, a simple assembly and a high strength wedging.
• the body -4- has, as usual, a series of retaining steps -13- with the lower edge -14- of the outer flange of the bottle neck, in the present invention also presenting an outer flange directed towards the outside -14'-, intended to receive the compression action inward of the tube cover -2-, which increases the pressure contact of the projecting edges -13- against the step -14- of the bottle neck. This greatly increases the force required to remove the cap assembly, which is therefore much safer against tampering for the filling of the bottle.
• the body -A- has the external thread thread -15- and multiple vertical bridges -16-, -16'-, -16 "-, ... equipped with multiple protrusions of small dimensions , distributed by zones, which have an upwardly pointed shape, having been designated in the drawing with the numerals -17-, -17'-, -17 "- ...
• Body -4- presents laterally the usual flexibilization windows such as -19-, -19'- ... and others of smaller dimensions -20-, -20'- ...
• the body of the non-refillable cap which has been indicated globally with the numeral -25-, is provided inferiorly with several wings separated from one another, gently inclined towards the outside, which have been indicated with numerals -26-, -27-, -28- and -29- that are separated from each other by continuity solutions or longitudinal cuts -30-, -31-, -32- and -33-.
• the number of sections -26-, -27-, -28- and -29- may be variable, four of which have been represented in the attached drawings, by way of example.
• the separation zones of the different sections mentioned may have a straight shape substantially according to planes substantially parallel to the longitudinal axis of symmetry of the plug body, but could have a different shape such as, slightly inclined, curved, etc.
• what has been proven essential for the purposes of the invention is the constitution of multiple lower wings -26-, -27-, -28- and -29- laterally separated from each other, so that each of they can be adapted correctly by means of their inner bottom edge at the bottom edge of the neck Of the bottle.
• the individual steps are observed, for example -34- and -35- for the wing -28- located below the corresponding wide openings such as those indicated by numerals -36- and -37-.
• the applicant has verified that the ease of assembly of the plug body in the automated assembly operation of the plug assembly is very simplified, achieving a considerable time saving and, on the other hand, the construction of the wings separated between if in the lower part of the body of the stopper it allows a better adaptation of the inner nerves of the body of the stopper in the neck of the bottle, giving rise to a more regular and firm support in all the common contour between the body of the non-refillable stopper and Bottom flange of the bottle neck.
• non-refillable caps according to the present invention, a simple manufacture of the molds for the washer and the body is achieved, as well as a simple assembly of the cap and a high anti-filling efficiency. A greater ease of assembly of the cap and a greater resistance to the surreptitious disassembly is also achieved.
• the commercially known and commonly used technical materials of greater or lesser rigidity will be chosen to adjust the characteristics of the pieces to favor their assembly.
• the body of the cap will be made of polycarbonate, although, as is understandable, it could also be manufactured in other technical plastic materials, especially of the appropriate type to prevent hot deformation.
