Abstract

The present invention relates to squeezer device for tubes containing fluid paste, in particular toothpaste. A piston (3), equipped with an expressly contoured slot (7) in which the rear part (8) of a tube (9) containing the fluid paste is inserted, can slide in a tubular casing which may be fastened to the wall. This tube bears via its front part (10) on the base (2) of this casing and emerges via its end (11) through a hole in the said base, whilst this piston is pushed forward by an appropriate means, such as a screw press (4) or a system composed of a manually or electrically controlled rack and pinion. The pressure exerted on the tube by the walls of the slot of the piston, as it advances, causes the expulsion of the paste. <IMAGE>

Description

L'invention concerne un exprimeur pour tubes contenant de la pâte fluide.The invention relates to an expressor for tubes containing fluid paste.

On sait que la méthode la plus commune pour presser un tu­be, par exemple de dentifrice, est celle qui consiste à l'é­craser avec les doigts.We know that the most common method of pressing a tube, for example toothpaste, is to crush it with your fingers.

Toutefois cette méthode-là n'est pas satisfaisante car au fur et à mesure que le tube s'amoindrit, de nouvelles diffi­cultés surgissent, à cause de la tendance de la pâte à reve­nir aux zones déjà pressées.However, this method is not satisfactory because as the tube becomes smaller, new difficulties arise, because of the tendency of the dough to return to the already pressed areas.

On sait aussi que l'opération de pressurage manuel compor­te une certaine complication puisqu'il faut empoigner le tu­be, enlever le bouchon, presser le tube, puis revisser le bouchon et reposer le tube; le tout en maintenant, en même temps, la brosse à dents en position horizontale.We also know that the manual pressing operation involves a certain complication since it is necessary to grasp the tube, remove the stopper, squeeze the tube, then screw the cap back on and put the tube back; all while keeping the toothbrush in a horizontal position at the same time.

L'invention consiste en un exprimeur de pâte en tube qui se propose et qui atteint les buts et avantages suivants:
- On l'actionne avec une simple et rapide manoeuvre des doigts.
- Il répond toujours par une expulsion prompte, précise et uniforme.
- Il consent d'épuiser le tube d'une manière progressive et complète.
- Il est particulièrement propre à être fixé au mur et, pour cela, il élimine la nécessité de soutenir et de manipuler le tube en réduisant ainsi le travail des mains.
- Il a un mécanisme simple, fiable et résistant.
- Il est durable et ne requiert aucun entretien.
- Il existe en versions assistées électriquement.
- Il est compatible avec presque tous les tubes en commerce.
- Il permet de rechanger le tube avec aisance et rapidité.
- On peut le munir d'un couvercle de protection contre la dessication de la pâte, couvercle qu'on peut ouvrir rapidement.
- Il est d'aspect agréable et il dissimule le tube à la vue.
- Il peut servir de support aux brosses à dents sans augmen­ter sensiblement l'encombrement (en tant que presse-dentif.).
- Il est de dimension réduite et constitue un ensemble compact.
- Il est facile à nettoyer car il a une surface uniforme et régulière.
- On peut l'employer de façon portative sans modifications significatives.
- Il n'est pas cher et pour cette raison il est largement ac­cessible aux usagers.The invention consists of a tube dough expressor which proposes and which achieves the following aims and advantages:
- It is activated with a simple and quick maneuver of the fingers.
- He always responds with a prompt, precise and uniform expulsion.
- He consents to exhaust the tube in a progressive and complete manner.
- It is particularly suitable for being fixed to the wall and, for this, it eliminates the need to support and handle the tube, thus reducing the work of the hands.
- It has a simple, reliable and resistant mechanism.
- It is durable and requires no maintenance.
- There are electrically assisted versions.
- It is compatible with almost all tubes on the market.
- It allows you to change the tube easily and quickly.
- It can be fitted with a protective cover against drying of the dough, which can be opened quickly.
- It is pleasant in appearance and it hides the tube from view.
- It can serve as a support for toothbrushes without significantly increasing the size (as a toothpick.).
- It is of reduced size and constitutes a compact unit.
- It is easy to clean because it has a uniform and regular surface.
- It can be used portable without significant modifications.
- It is not expensive and for this reason it is widely accessible to users.

Le présent exprimeur de pâte en tube, tel qu'on le rap­pelle dans les revendications, est caractérisé par le fait qu'il comprend un piston doté d'une fente dans laquelle on insère la partie postérieure d'un tube contenant de la pâte fluide. Cette fente est silhouettée de manière à ce qu'un relatif glissement coaxial du système piston-tube induise sur le tube la pression nécessaire pour exprimer la pâte.The present tube dough expressor, as recalled in the claims, is characterized in that it comprises a piston provided with a slot into which the rear part of a tube containing fluid dough is inserted. . This slot is silhouetted so that a relative coaxial sliding of the piston-tube system induces on the tube the pressure necessary to express the dough.

Le dispositif comprend aussi un corps propre à servir de support au dit système de fonctionnement, en le contraignant convenablement et, en même temps, en lui permettant le mouvement nécessaire. Ce corps est préférablement constitué par une enveloppe tubulaire dans lequel ce piston peut glisser; ladite enveloppe est convenablement fermée aux extrêmités, la fer­meture inférieure constituant un soutien pour le tube, le­quel est appuyé par sa partie antérieure, sauf le bec qui sort par un trou présent sur ce même fond; le fond en ques­ tion peut éventuellement être assorti d'un couvercle de pro­tection. L'enveloppe sus-mentionnée peut facilment être fi­xée au mur au moyen, par exemple, d'un appendice qui se de­gage de la surface latérale, et pourvu de moyens de fixati­on, par exemple des trous pour vis.The device also comprises a body suitable for serving as a support for said operating system, by constraining it properly and, at the same time, allowing it the necessary movement. This body is preferably constituted by a tubular envelope in which this piston can slide; said envelope is suitably closed at the ends, the lower closure constituting support for the tube, which is supported by its front part, except the spout which comes out through a hole present on this same bottom; the bottom in ques tion can optionally be accompanied by a protective cover. The above-mentioned envelope can easily be fixed to the wall by means, for example, of an appendage which emerges from the lateral surface, and provided with fixing means, for example holes for screws.

Le tube accède dans l'enveloppe par un des bouts suscepti­ble d'être ouvert, ou bien par un volet pratiqué dans la sur­face latérale de l'enveloppe.The tube enters the envelope through one of the ends which can be opened, or else through a flap made in the lateral surface of the envelope.

Le piston sera poussé par n'importe quel moyen en mesure de lui imprimer une translation le long de son axe. Par exemple on indique une presse à vis qui profite, comme appui de for­ce, de la fermeture de l'enveloppe; ladite vis peut être do­tée d'une petite poignée pour la manoeuvre manuelle, ou bien, on peut l'actionner, par l'intermédiaire d'un pignon spécial, par un moteur électrique, alimenté en réseau ou par batteries.The piston will be pushed by any means capable of imparting a translation along its axis. For example, a screw press is indicated which takes advantage, as a force support, of the closing of the envelope; said screw can be provided with a small handle for manual operation, or it can be actuated, by means of a special pinion, by an electric motor, supplied by network or by batteries.

On peut obtenir une alternative équivalente à la réalisation précédente en remplaçant la presse à vis par une crémaillère gouvernée par un pignon qu'on peut tourner manuellement ou é­lectriquement. Un tel mode de réalisation consent d'encastrer le piston à l'extrêmité inférieure de la crémaillère, de sor­te qu'il est possible de commander le mouvement du piston dans les deux sens.An alternative equivalent to the previous embodiment can be obtained by replacing the screw press with a rack governed by a pinion which can be turned manually or electrically. Such an embodiment consents to embed the piston at the lower end of the rack, so that it is possible to control the movement of the piston in both directions.

Un autre mode de réalisation, analogue au précédent, est en­visageable en invertissant la disposition du système crémail­lère-pignon; c'est-à-dire en fixant la crémaillère à l'enve­loppe le long d'une génératrice et en montant le pignon sur le piston. Naturellement le pignon doit être à portée de la main, ce qu'on peut obtenir en prolongeant son axe à travers une ouverture dans l'enveloppe et en le complétant par une petite poignée; cette ouverture peut être une cannelure lon­gitudinale, nécessaire et suffisante au pignon pour suivre la course du piston.Another embodiment, similar to the previous one, can be envisaged by inverting the arrangement of the rack-pinion system; that is to say by fixing the rack to the casing along a generator and mounting the pinion on the piston. Naturally the pinion must be within easy reach, which can be achieved by extending its axis through an opening in the envelope and completing it with a small handle; this opening can be a longitudinal groove, necessary and sufficient for the pinion to follow the piston stroke.

Dans la version électrique correspondante, au contraire, le pignon peut rester dans l'enveloppe, car il suffit de monter sur le piston le moteur lui-même et les rouages correspondants. Il va sans dire qu'il y aura des dispositifs ad hoc pour la con­duction et le contrôle du courant.In the corresponding electric version, on the contrary, the pinion can remain in the casing, because it suffices to mount the motor itself and the corresponding cogs on the piston. It goes without saying that there will be ad hoc devices for current conduction and control.

Je crois que le noyau central de l'invention réside dans la conformation particulière de la fente du piston et dans l'ef­fet qui s'ensuit sur le tube tandis que le piston glisse, le reste étant conçu dans le but de garantir cet effet.I believe that the central core of the invention resides in the particular conformation of the piston slot and in the effect which follows on the tube while the piston slides, the rest being designed in order to guarantee this effect.

Le principe de l'invention sera rendu plus clair par la de­scription détaillée d'un mode de réalisation illustré à titre purement indicatif et pas du tout limitatif de sa portée. En particulier, cette description concerne une version entière­ment mécanique, choisie dans l'intention de rendre immédiate la compréhension du principe de l'invention, étant donné qu'une version électro-assistée est une facile dérivation de l'invention ainsi conçue.The principle of the invention will be made clearer by the detailed description of an embodiment illustrated for information only and not at all limiting its scope. In particular, this description relates to an entirely mechanical version, chosen with the intention of making the understanding of the principle of the invention immediate, since an electro-assisted version is an easy derivation of the invention thus conceived.

Conformément à la présente invention, les figures citées ci-dessus se réfèrent à un exprimeur de pâte en tube qui com­prend une enveloppe tubulaire cylindrique 1 avec le fond fer­mé 2 dans lequel peut glisser un piston 3 poussé vers ce fond 2 par la vis d'une presse 4 associée au centre d'un premier couvercle 5 vissé sur la même enveloppe 1 .In accordance with the present invention, the figures cited above refer to a tube dough expressor which comprises a cylindrical tubular casing 1 with the closed bottom 2 in which a piston 3 can slide pushed towards this bottom 2 by the screw a press 4 associated with the center of a first cover 5 screwed onto the same casing 1.

Cette vis 4 , sur son extrêmité sortant de cette enveloppe 1 , est dotée d'une petite poignée 6 de manoeuvre.This screw 4, on its end leaving this envelope 1, is provided with a small handle 6 for maneuvering.

Ce piston 3 est pourvu en longeur d'une fente 7 adéquate­ment silhouettée selon une forme assimilable à un entonnoir courbe, fente dans laquelle est insérée la portion postérieu­re 8 d'un tube 9 contenant du dentifrice dont la portion antérieure 10 repose sur le fond 2 de ladite enveloppe 1 . L'extremité 11 du tube 9 sort par un trou 12 de ce fond 2 .This piston 3 is provided in length with a slot 7 suitably silhouetted in a shape similar to a curved funnel, slot in which is inserted the rear portion 8 of a tube 9 containing toothpaste whose front portion 10 rests on the bottom 2 of said envelope 1. The end 11 of the tube 9 exits through a hole 12 in this bottom 2.

La poussée de la vis 4 sur le piston 3 le fait descendre en sorte que les parois de la fente 7 exercent sur le tube 9 la pression nécessaire pour exprimer la pâte.The thrust of the screw 4 on the piston 3 causes it to descend so that the walls of the slot 7 exert on the tube 9 the pressure necessary to express the dough.

A l'extérieur, cette enveloppe 1 est munie d'un appendice 13 apte à la fixation au mur par l'intermédiaire de vis, et d'une couronne 14 pourvue de trous 15 dans lesquels on peut insé­rer les brosses à dents 16 .On the outside, this envelope 1 is provided with an appendage 13 suitable for fixing to the wall by means of screws, and with a crown 14 provided with holes 15 in which the toothbrushes 16 can be inserted.

A l'extérieur de ce fond 2 est fixé par une charnière un second couvercle 17 apte à protéger l'extrêmité 11 du tube 9 .Outside this bottom 2 is fixed by a hinge a second cover 17 able to protect the end 11 of the tube 9.

Le pas de la vis 4 est calibré de façon qu'une petite rota­tion produise l'expulsion demandée.The pitch of screw 4 is calibrated so that a small rotation produces the requested expulsion.

L'exacte courbure à conférer aux parois de la fente 7 est déterminable à travers quelques essais expérimentaux à partir de la configuration théorique illustrée dans la figure 5 .The exact curvature to be given to the walls of the slot 7 can be determined through a few experimental tests using the theoretical configuration illustrated in FIG. 5.

On effectue le chargement de la manière suivante: on in­ troduit le tube 9 renversé dans l'enveloppe 1 avec son ex­trêmité 11 saillant par le trou 12, ensuite on met le pi­ston 3 en ayant soin d'insérer la portion postérieure 8 du tube 9 dans la fente 7 et, à la fin, on visse le couvercle 5 qui porte la vis 4.The loading is carried out as follows: on in troduit the tube 9 overturned in the casing 1 with its end 11 projecting through the hole 12, then we put the piston 3 taking care to insert the rear portion 8 of the tube 9 in the slot 7 and, at the end, screw the cover 5 which carries the screw 4.

Cette invention, on peut la réaliser, en tout ou en partie, en matière plastique, toute autre matière appropriée pou­vant cependant être utilisée.This invention can be carried out, in whole or in part, in plastic, any other suitable material that can however be used.

Il va sans dire que toutes les dimensions sont facultati­ves, suivant les exigences.It goes without saying that all dimensions are optional, depending on requirements.

L'invention ainsi conçue est susceptible de différents mo­des de réalisation ( outre ceux qui ont eté précédemment exposés ) et d'autres variantes, formes et modifications re­levant toutes du principe de l'invention.The invention thus conceived is susceptible of different embodiments (in addition to those which have been previously exposed) and other variants, forms and modifications all relating to the principle of the invention.

En outre, on peut remplacer chaque élément par un autre é­lément techniquement équivalent; par exemple, on peut rem­placer l'enveloppe tubulaire par un autre élément ayant les mêmes fonctions, comme par exemple une cage, même réduite à peu de barreaux.In addition, each element can be replaced by another technically equivalent element; for example, the tubular casing can be replaced by another element having the same functions, such as for example a cage, even reduced to a few bars.

Le présent exprimeur de pâte en tube est, dans toutes ses formes, aisement réalisable dans l'industrie. On peut ef­fectivement le fabriquer à des coûts réduits au moyen des installations usuelles; en particulier, on peut obtenir les parties en matière plastique par l'estampage par presse à injection thermoplastique.The present dough tube expressor is, in all its forms, easily achievable in industry. It can actually be manufactured at reduced costs by means of the usual installations; in particular, the plastic parts can be obtained by stamping with a thermoplastic injection press.
