NON-REMOVABLE VALVED SPOUT FOR BOTTLES

Abstract: A valved dispensing spout which can be easily assembled and non-removably attached to the neck of a bottle. It includes a double-headed shiftable valve element (15, 18, 20, 21), a threaded overcap (9) and a sleeve (4) for locking the spout to the bottle neck. Teeth (7) at the top of the sleeve (4) fit into recesses (8) at the bottom of the overcap (9) and will break when the overcap (9) is unthreaded for the first time.

Description: Descriptive Report of Patent about a utility model in¬ volving an " Non-removable Valved Spout for Bottles The present model concerns about - the introduction of peculiar construtives dispositions - about inviolable valvular lids for bottles, in view to increase the grade of security of this inviolability - and to improve the valvular dispositive, specially to make easier the coupling and the fixation of the whole set in the bottle neck, avoiding the usual complicated - operations offered by many of the known solutions for making the coupling and the fixation. Thus, taking a bottle neck contain¬ ing two saliences in its external diameter, being one in the mouth area and the other adequately from the - former, the proposed model includes a skirt involving the upper area of the neck, a valved nozzle that ad¬ justs to the neck mouth, and an additional lid invol , ving all the emergent part of the valvular mouth of the flask. In the external skirt of the neck, the pro- - posed model shows in its circular internal face, to the inferior level, a flange up-projected and inclina¬ tion, that may be unique, continuous, taking the whole circunference of this face or may be segmented. The - above referred external skirt shows still in its in- - ternal circular face and near its superior border, ano ther flange low-projected and in inclination that may be unique and continuo s,involving the whole circunfe- rence of this face, or may be segmented. At this supe¬ rior border of these external skirt and at the level - of its external face, are foreseen little teeth that - are inserted in the corresponding cavities of the ex¬ ternal face of the overlid, joint to this inferior bor der, in a may that when we turn on for the valvular - nozzle and for outled the liquid, the above referred - - teeth are necessarely broken composing the brake of the first seal. In the proposed model the valvular nozzle is composed by a tappet substantially cylindri¬ cal hollow, with a wide inferior hole whose external - - circular face remains introduced in the neck's mouth of the flask, contacting with the internal face of this area. At the upper part, the referred tappet - shows an orthogonal rim of section, substantially pri atic whose top touches the border of the necks mouth, - limiting the introduction of the tapped into the neck of the flask. The nozzle, properly said, inside of which runs one valve and one counter-valve with li i — ted course, reveals at the inferior part an external - diameter, adjusted to the internal diameter of the re- - ferred tappet, affixed in it, so that after the refer¬ red tappet, the body of the nozzle widen in its diame¬ ter until the superior border in which is fixed the valve's superior disc. Prom the medium area of the cir cular external side of the nozzle part of larger diame - ter, an external cape of the flask's mouth stand out, OM composed by a circular side, inicially trunk-conical,- which in the area of touching with the internal face of the over lid side starts low-pro ecting vertically, as in this area will be foreseen corresponding threa- - ded arrangements, as much as, in the internal face of the over lid, as well as, in the external face of the nozzle side, that continues to be low-pro ected until its border touches the salience of the external diame¬ ter of the neck mouth, in which proximity is foreseen - a circular external hollow, where the flange will cou¬ ple, low-projected and in inclination from the inter - nal face of the external skirt of the neck mouth. At the proposed model, the security valve shows from the inferior face of the superior disc, radial roads tur- - ned to the center, with larger amplitude in its supe¬ rior part and present in its lateral inferior border - little teeth that limit the course of the valve when - touching the inferior border of the nozzle part of mi¬ nor diameter, that is introduced into the neck. At - last, the proposed model shows one counter-valve, com¬ posed by a trunk-conic inverted plate from whose supes rior face is projected a centralized faceted pin, that slides and adjusts between the valve vertical rods so that if the valve is turned on, the counter-valve will - perform necessarily the same moviment. Thus with these dispositions,on top of coming much easier the coupling of all dispositive to the neck of the bottle, the component elements get fixed and held one to another, so, the security of the - inviolability comes sensibly encreased. OMPI So far, for a better understanding of how is constructed the present invention it is pre¬ sented in an unique attached figure of it with an illustrative purpose and non restrictive one, where - the peculiar model is shown in a vertical projection - applied in one bottle neck with demonstratives cuts. Therefore, according to these illus_ tra-tions and its details, the proposed model includes a neck(l) containing two saliences(2) and (3) in its - external diameter, being one(3) in the area of the mouth, and the other(2) adequately remote from the first one, showing at the external skirt(4) surrounding the neck(l) in its internal side, at inferior level, - one flange, (5) up-projected and in inclination, that - may be unique, continuous, involving the whole circum¬ ference of this side, or may be segmented, presenting also this internal side, and from the external skirt (4) now at the proximity of its circular superior bor¬ der another flange(6) low-projected and in inclination, - that may be unique and continuous involving the circun ference or may be segmented, having the referred exter nal skirt little teeth(7) up-projected from its supe¬ rior border, which are inserted in the corresponding - cavities(8) of the external face of the overlid(9)near - the inferior border of this latter, so that when the overlid get threaded for the first time to let free - the valvular nozzle for outleting the liquid, the re¬ ferred teeth(7) are necessarely broken constituting - the rupture of the first seal. - In the proposed model, the valvular O nozzle is formed by a tappet(10) substancially cylin - drical, empty with a wide inferior hole(ll)whose exter nal circular side is introduced adjusted in the area - of the neck mouth, showing the referred tappet(10) one - superior orthogonal rim(12)turned outside and of subs_ tancially prismatic section, whose top touches the border of the neck mouth, limiting its introduction in this neck extreme part(l) as the nozzle includes yet a tubular boby with the inferior part(13) of minor diame - ter which adapts and fixes in the internal part of the tappe (10) in adequate length, as after the referred - tappet the tubular body presents in(14) major diameter until its superior border in which is fixed the valve disc(15)« In a medium height the external side of this - larger diameter jut out one nozzle external cover(16)- for ed at first from one circular trunk-conic side - that in the area of touching with the internal face of the overlid side(9) starts to be projected inferiorly, vertically, being foreseen in this area, dispositions of corresponding thread either in the internal face of - the overlid side, as well as, in the external face of nozzle's side which continuous to be projected infe¬ riorly until its border contacts the border of the sa- lience(3) of the external diameter of the neck's mouth at which proximity is foreseen a circular external - - lowering(17) where are inserted the flanges(β) turned to the bottom and in inclination, from the internal fa ce of external skirt(4) of the neck(l). In the present model, the security valve shows, from the inferior face of the superior - - ORE T- OMPI disc, radial, rods(18) turned to the center with lar - ger width in its superior part, presenting in the infe_ rior lateral border, little teeth(19) that limit the course of the valve when touching the inferior border - of the part of less diameter(13) of the nozzle, intro¬ duced in the tappet(lθ). At last, the proposed model reveals one counter-valve formed by one inverted trunk -conic plate(20) whose major diameter is larger than the inferior hole(11) of the tappet(10) and from which - superior face is projected, centralized, one faceted - pin(21) that slides and adjusts between the vertical rods(18) of the valve, so that when the valve is tur ned, the counter-valve will be necessarely driven to perfoim this movement. - The setting of this peculiar cover, as well as its coupling to the neck mouth, does not show any difficult. At first setting, the valves with the rods(18) are placed in the interior of the tubular body, afterwards inserting the counter-valve in the - lower-part. Subsequentelly, the tubular body will be inserted by its inferior part(13) of less diameter in the tappet(lθ) after proceeding to the thread operation in the nozzle external cover of the overlid(9) thus, - completing this set, still separated from the neck. - - After wards the external skirt(4) will be applied to the neck, in order to be retained by the insertion of its flange(5) in the hollow determined by external sa¬ lience(3) of the neck mouth. Finally, the set formed - by the overlid(9) by the nozzle containing the valve - and the counter-valve and by the tappet(10), is taken OM and placed in the neck, in a way that the tappet will be introduced in the interior of the neck until the de_ ter ined limit by the contact of this orthogonal(12) - rim to the superior border of the neck's mouth, moment - in which the internal flange(β) of the external skirt- (4) will be inserted in the circular external hollow - (17) of the external nozzle's cape, thus, completing - the solidity and inviolability of the coupling,so that, the peculiar cover might be violated only if broken. - - Also in this final moment of the coupling, the teeth - (7) will meat a seat in the radial hollow-places(8) so as to form a first seal, once the overlid ' etting uns¬ crewed for the first out let of the liquid, the re¬ ferred teeth are necessarely broken. -gtϊRE .
