Definitions

  • dispensers of semi-consistent products formed of a cylindrical case capped by a high-grip pump and provided at its opposite end, usually its lower end capable of serving as its seat, with a movable bottom that the atmospheric pressure increases as the product is withdrawn by the pump. This makes it possible both to keep the dough or cream, or even the liquid, away from the air, and to methodically expel them during use.
  • the movable bottom normally has two divergent tight lips; one is then directed inwards, possible internal overpressures increasing its application on the wall of the case but without creating a bracing: it essentially serves as a scraper; the other, facing outwards, is on the contrary better applied when it reacts to internal depressions, that is to say when a product is removed: it thus plays the essential sealing role.
  • patent publication FR-A-2 605 983 (cf.
  • preamble of claim 1) according to which the bottom, remaining accessible to the operator through an axial opening made at the lower end of the case, however, is retained by an internal relief of diameter slightly less than those of its lips of the bottom and forming by its high reach a stop ring in abutment, but on the contrary having a flared entry and through which the bottom can thus be put in place after filling.
  • the invention proposes to overcome these drawbacks. It increases the shelf life of the product and makes operation safer at the start of use. To achieve this, two complementary peripheral surfaces which are not very oblique to the axis, one placed at the bottom of the case, the other on the movable bottom, will cooperate in tightening when the bottom, kept accessible to the operator, will have been placed in the extreme position, here deemed to be low, which it occupies on the device at the end of filling, thereby retaining it there and thus adding an auxiliary seal.
  • the tightening of the auxiliary seal is further limited by an axial stop; preferably also, the auxiliary sealed bearing surface which belongs to the movable bottom is separated from its external lip and placed on a more rigid part of this bottom.
  • the dispenser shown in Figure 1 comprises a cylindrical barrel 1 which supports a sleeve 2 and receives a piston 3 retained by a ring 4 ; this can range from a simple ring or circlip to a double bottom leaving an air inlet.
  • the neck 2 a constitutes a well which receives the pump body 5 a inside of which a flange 5 b retains the piston 6 , the rod 6 of which forms a nozzle carrying a head 7 serving as a pusher and equipped with an adequate nozzle. It is convenient to use the collar 5 b , masked here by the lower edge of the head, to fix the pump to the container, for example as shown in the figure. A cover can protect the assembly.
  • the shoulder 2b internally creates a roof whose conical shape corresponds to that of the piston or movable bottom 3 , avoiding air pockets and loss of product; its connection to the neck 2 has a seat 2 c where the end of the pump body is inserted, flush, its shoulder 5 c can come into abutment to complete the seal.
  • the piston 6 which an internal spring (not shown) returns upwards, also makes a seal on the collar 5 b ; if the pump is fitted with a vent 5 d , the latter will be neutralized by the seat 2 c which thus keeps the product 8 sheltered from the air.
  • This conventional construction makes it possible to manufacture all of the parts by injection and, advantageously, to mount them by interlocking; it is generally preferred to constitute the socket of a part that is not integrated into the barrel, the pump body, or even its cap, but independent, since it is thus possible to use pumps of standardized manufacture, produced and assembled in large series.
  • the movable bottom 3 can be introduced from the top before filling and the ring 4 can not be added as shown in the figure but formed by a simple internal return from the wall of the barrel 1 .
  • the movable bottom 3 preferably has two lips 3 a and 3 b directed in opposite directions from a belt 3 c .
  • the lip 3a which can thus remain off the top of the bottom, serves essentially scraper during ascent under the effect of the depression created by the pump, preventing any irregularity consistency and behavior of the product coming raise the lip 3 b which, for its part, serving essentially to prevent any entry of air from the bottom, plays the main role and forms the sealing lip proper.
  • the bottom 3 is further provided with a pusher 3 d .
  • Figure 2 shows on a larger scale a first embodiment of the lower part of the barrel according to the invention. Its wall simply has a lower part offering a slightly conical bearing surface 1 a , the tightening of which downwards, without causing jamming, increases the tightening on the lip 3 b when the bottom is brought into the low end of filling position.
  • Figure 3 shows a more advantageous version, in which the barrel wall remains cylindrical but the bearing which causes the tightening in a downward movement belongs to the oblique rear face of the lip 3b , which comes to bear at A , creating a secondary seal, on the rounded edge of a projection 4 has here forming the internal back of a stop ring 4 reported; in the extreme position, the lip 3 b will thus be applied in extension towards the wall of the barrel 1 and in a way clamped in the groove drawn by the projection 4 a .
  • FIG. 4 shows a variant in which it is with the internal crown 3 e of the movable base 3 that the projection 4 a cooperates in slightly oblique clamping at A , along two oblique or cylindrical bearing surfaces with rounded inputs , distinct from the lip and more rigid.

Claims (9)

  1. Spender für flüssige Produkte, bestehend aus einem zylindrischen Gehäuse (1), das eine Pumpe (5/6) trägt und das an seinem gegenüberliegenden Ende, welches als Grundplatte dienen kann, mit einem beweglichen Boden (3) versehen ist, der zumindest eine Dichtungslippe (3b) besitzt und durch einen Ring (4) zurückgehalten wird, wobei der bewegliche Boden für einen durch den Benutzer ausgeübten externen Druck, mittels einer axialen Öffnung, die am unteren Ende des Gehäuses vorgesehen ist, zugänglich bleibt, dadurch gekennzeichnet, daß zwei bezüglich der Achse leicht geneigte periphere und komplementäre Paßflächen vorgesehen sind, eine im unteren Teil des Gehäuses, die andere am beweglichen Boden, die durch Anpressung (A) zusammenwirken, wenn sich der Boden nach Beendigung der Füllung in seiner untersten Position befindet, was diesen zurückhält und damit eine zusätzliche Abdichtung erzeugt.
  2. Spender nach Anspruch 1, dadurch gekennzeichnet, daß die untere Position des Bodens und die Anpressung der zusätzlichen Abdichtung durch einen axialen Anschlag (3f) fixiert ist.
  3. Spender nach Anspruch 1, dadurch gekennzeichnet, daß ein Element des Bodens (3d,3e) in der unteren Stellung leicht über die Hülse und über die Grundplatte des Gehäuses vorsteht.
  4. Spender nach Anspruch 2, dadurch gekennzeichnet, daß der bewegliche Boden mit einem umlaufenden Vorsprung (3c) versehen ist, der die Dichtlippe (3b) trägt und der sich in einer Krone (3e) fortsetzt, um mit einem nach innen gerichteten Vorsprung des Arretierringes (4) in Anschlag zu kommen.
  5. Spender nach den Ansprüchen 3 und 4, dadurch gekennzeichnet, daß sich die Anschlagskrone (3e) über eine Stützpaßfläche (3f) hinaus erstreckt, so daß sie leicht über die Grundplatte vorsteht.
  6. Spender nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß seine Wandung einen unteren Teil besitzt, der eine leicht konische Paßfläche (1a) bildet, deren Verjüngung nach unten hin zur Anpressung mit der Dichtlippe (3b) zunimmt, wenn sich der Boden in seiner unteren Position befindet.

  8. Spender nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß die Paßfläche des beweglichen Bodens, bei der es zur Anpressung (A) kommt, von der Dichtungslippe (3b) getrennt ist, und auf einem steiferen Teil des Bodens angeordnet ist.
  9. Spender nach Anspruch 8, dadurch gekennzeichnet, daß die Teile des Bodens und des Gehäuses, die die Paßflächen zur Anpressung (A) tragen, zusammenwirken, um durch das Zusammemspiel zweier federnder Ringe (9) mit einem Hinterschnitt einen festen Punkt zu schaffen.
