Abstract
There is described a dispensing pump for a fluid con-tained in a container, in which the component parts form two units which are functionally joined together by a coupling member (26), while being easily separable. The component parts of each unit are assembled together in such away as to make them hardly separable. The second unit comprises a valve (56) for communication with the container (28) and is in-separably attached to the container (28) and is further provided with a device restraining access to the valve (56), whereby this unit acts as a seal for the container. The first unit comprises a cylinder (2), piston (6), actuator means (14), spring (16) and communication means (8, 12) with the external environment and is applicable to successive second units.
Description
(~~..9~a A DISPENSING PUMP FOR A FLUID CONTAINED IN A CONTAINER
D E S C R I P T I O N
The invention relates to a dispensing pump for a fluid contained in a container, said pump having: a) a first group of members comprising: a cylinder defining a pumping chamber;
a piston adapted to slide within said cylinder; actuator means for said piston; a resilient member engaging said piston; first communication means between the pumping chamber and the external environment; a first valve for regulating said communication with the external environment; and a member -For coupling with the container; and b) a second group of membesr cornprising: communication means between the 1.5 pumping chamber and the container; and a second valve for regulating said communication with the container.
Containers holding a fluid preferably for hygiene or cleaning purposes are being ever increasingly used particularly in the home. The container is regularly and 2U desirably provided with a dispensing pump which facilitates the application and even the metering of the fluid to be used, there being contemplated also the possibility of the pump allowing for spraying and even foaming of the contained fluid. The pump is also frequently irreversibly connected to 25 the container, forming a sort of guarantee seal for the quantity and the quality of 'the contents.
The situation referred to shortly in the foregoing para-graph suffers from the drawback that it is necessary to acquire a complete pump with each container, bottle or the 3U like, with said pump being useless for the user after 'the content of the container has been usod. 'fho recovery or recycling of 'the pump by the manufacturer is not reasonably foasible either, which makes use more expensive.
To overcome the above drawback, 'the present invention 35 seeks to provide a pump of the type mentioned abovo charac terised fundamentally in that said First group and said second group respectively 'Form First and s~corod units, 'the members of each of which are assernbled together 'in a way making them hardly separable, said second ur7it being adapted to be inseparably attached to the container, said first and second units being functionally connected together by said coupling member and in that downstream of said second valve there is a device restraining access to said second valve.
With the pump of the invention, the user first purchases a container with the complete pump. When the contents have been used, he removes the first unit and disposes of the container together with the second unit.
when replacing the product, he only needs to purchase a new container with a new second unit and mount the initial first unit to the new purchase, with obvious saving, since said first unit comprises a major portion of the pump members which are, furthermore, the most expensive ones.
With the second unit being inseparably attached to the container, it obviously acts as a seal preventing tampering with the content of the latter. The security of this arrangement is due in part to it being impossible to empty the container without the aid of the first unit and in part to refilling of the container being prevented due to the above-mentioned restriction of access to the second valve which regulates communication with the interior of the container.
Therefore, in accordance with the present invention, there is provided a dispensing pump for a fluid contained in a container, said pump having: a) a first group of members comprising: a cylinder defining a pumping chamber; a piston adapted to slide within said cylinder;
actuator means for said piston; a resilient member engaging said piston; first communication means between the pumping chamber and the external environment; a first valve for regulating communication with the external environment; and a member for coupling with the container; and b) a second group of members comprising:
- 2a -second communication means between the pumping chamber and the container; and a second valve for regulating communication with the container, said first group and said second group respectively forming first and second units, the members of each of which are practically inseparably assembled together, said second unit being adapted to be practically inseparably attached to the container, said first and second units being functionally connected together by said coupling member and in that downstream of said second valve there is a device restraining access to said second valve.
Also in accordance with the present invention, there is provided a dispensing pump for a fluid contained in a container, comprising:
a) a first group of members including--a cylinder defining a pumping chamber, a piston adapted to slide within said cylinder, means for actuating said piston, a resilient member engaging said piston, first communication means between the pumping chamber and the external environment, a first valve for regulating said first communication means, and a member for coupling with the container, and b) a second group of members including--second communication means between the pumping chamber and the container, a cup-shaped member having an open end, a side portion and a bottom portion in which there is formed a passage forming part of said second communication means, and a second valve for regulating said second communication means, wherein said cylinder has a first open end insertable into said open end of said cup-shaped member - 2b -and received by said side portion thereof, said first group and said second group respectively form first and second units, the members of each of which are practically inseparably assembled together, said second unit and container including retaining means for practically inseparably attaching the second unit to the container, said first and second units being reparably connected together by said coupling member and downstream of said second valve there is a device restraining access to said second valve, said restraining device being associated with said bottom portion of said cup-shaped member.
Further advantages and features of the invention will be appreciated from the following description, in which preferred embodiments of the invention are described without any limiting nature, with the reference to the accompanying drawings in which:
Figure 1 is an elevation view, partly in cross section on a diametral plane, of the dispensing pump according to the invention in the maximum compression state, part of the container being shown in section;

The dispensing pump of the invention is in many ways no dif-Fe~r-ent from a conventional pump. Therefore, it is provided with a first group of members to be referred to hereinafter.
In the first place there is a cylinder 2 defining therein a pumping chamber ~1 which is shown in Figure 1 to be in its smallest capacity position. Associated with the cylinder 2 there is a piston 6 adapted to slide within 'the cylinder between a first position (Figure 2) determining the maximum volume of the pumping chamber and a second position (Figure 1) corresponding to the minirnum volume of said chamber 4. It should be noted, however, that the cylinder of the invention has no bottom, to which further reference will be made here-inafter.
In the example shown, the piston 6 is extended by a hollow stem 8 associated with a tube 10 of a dispensing nozzle 12, 'in such a way that the piston 6 and stem 8 are attached to the tube 10 and nozzle 12 and may be moved there by, whereby the upper surface 14 of the nozzle 12 represents an actuator means for the piston. Obviously a force applied to said surface causes the piston 6 to slide within the cylinder 2. A resilient member or spring 16 engages said piston 6 and urges it to 'the said first position.
The association of the hollow stem 8, tube 10 and nozzle 12 forms first communication means between the pumping cham ber 4 and the external environment. This communication is regulated by a valve 18 formed by a valve seat 20 and the stopper 22. No further details of 'the type of valve Shawn are given, since the configuration and special operation thereof are Foreign to the present invention. The valve 18 is urged to the closed position thereoF by a spring 24 and opens in due time to allow the flwid contained in tha purrlping chamber to ba dispensed.
A coupling member 26 allows the pump to be connected to the container 28. Tn the example shown, the mernber 26 is derlorally hood-shaped and is provided with an internal thread 30 adGtptod to engage a thr~ad 32 of the container neck. Further hereinafter another way of threaciinq the member 26 will be disclosed. It should ,:vlso be noted that the member 2G rnay be attached by other means, such as by a tHri~~t loci; or any other apropriate means allowing an eas~~~'~
y reversible connection to be made between the pump and the container 28.
The pump is also provided with assembly means allowing the first group of members described to form a first unit wherein the component members are assembled together in a way making them hardly separable. In the example shown, there is a assembly member 34 which is outstanding for the assembly of said first unit.
The assembly member 34 is provided with a cylindrical por't'ion 36 extended to the outside by a skirt portion 38, between which a.r~ upper crown 40 extending -From 'the cylinder 2 is retained. The connection may be by way of 'threads or be a press fit between mating retaining grooves. The cylinder is also provided with a tab 42 and between the said tab and -the lower edge of the skirt 38 there is loosely contained a por-tion of the coupling member 26, whereby the assembly of said member 26 is ensured.
The cylindrical portion 36 of the assembly member 34 extends inwardly over a frustoconical portion 44, from which there emerges an upper tubular portion 46 serving as guide for the nozzle tube 10 and the lower tubular portion 48 which guides the holloww stem 8 and limits the upstream movement of the piston 6. It is easy to imagine the operations required for assembling the first unit, whereby the description there of is omitted.
It should be noted once again that a simple example of assembly has been described and that the invention comprises other rational solutions appropriate -For the intended pur-pose. The first un it is shown in Figure 2.
The pump is provided also with a second group of members among which there i~~ a passage 50 compr-isod within the com-munication means between the pumping chamber 4 and the interior of the contairmr. Within t~.his passage; there is a valve sEat 52 and the stapper 54 forming thorebotween a second valve 56 regulating the communication between the chamber 4 and the: container.
Pre. Ferably the sari second group also rornprnses a cup-shnped mernber 58 provided wi th the ~:~as~,age 5u ar7d which houses said second valve .'>6, whereby there ns Formed a second _ 5 -unit in which all the members thereof are assembled together in a way making them hardly separable.
Thus, the member 58 is provided with an open end 60 terminating a rounded and preferably slightly conical side portion 62 tapering outwardly towards the open end, within which there is fitted the cylinder 2. The fit between the cup-shaped member 58 and the cylinder 2 is sufficiently snug to insure due tightness, but allows the first un it to be easily separated from the second unit.
The member 58 is pravided with a bottom portion 64 in which, as said above, there is situated the passage 50 and said bottom 64 acts as bottom -For the cylinder 2 and, there-fore, also as bottom for 'the pumping chamber 4.
T he second unit is adapted to be inseparably attached to the container, to which end the member 58 is provided with attachment means. In one embodiment (Figures 1, 3 and 4) said means comprises a continuous resilient ex-ternal flap 66 (or a plurality of separate flaps situated at the same level), which is divergently orientated relative to the side portion 62.
The flap 66 is provided to engage the container 28 which is provided with a widened portion 68 the upper edge 70 of which is orientated generally normal to the ideal axis of the pump. The resilience of the flap allows the member 58 to slide downwardly along the neck 71 of the container and, on reaching the level of the widened portion, the flap 66 takes on the position shown. In this way the second unit is in-separably attached, whereby in practice the second unit may anly be rernoved by destroying it.
In a -Further embodiment (Figure 5) there is a skirt member 72 extending from the edge 74 aF the apen encJ 60 aF
the cup--shaped rnernber 58. Said skirt rnernber extends generally coaxially to the side parlion 62, leaving a space there-betw~on to contain a portion of the neck 71 of thre container 28. On the inner surface 76 of the skirt rnembor and, there-fore, Facing the side portion 62, there is at least one harpoon-shaped prajoction 78 which is adapted to be retained by a shaulcior 80 of the neck 71. Irr tiois case also, the attachment of the second unit to the container 2Ei is ~~~J
sufficiently strong for its release to require, in practice, destruction of the second unit. In this embodiment the skirt member 72 is provided with a thread 82 capable of engaging the internal thread 30 of the coupling member 26.
It will be noted that the first and second units are firmly but separably functionally attached together, by way of the coupling rnember 26 which is threadedly attached either to the thread 32 of the neck or the thread 82 of the skirt member 72, in any case a-Fter having inserted the cylinder 2 inside the cup-shaped member 58. It is obvious that to separate the two units it is sufficient to unscrew the coupling rnernber 26 or, if necessary, undo the reversable connection between 'the Coupling member and the neck or skirt rnembe r .
A further important feature of the pump described is that the container may not be refilled while the second unit is retained on the neck 71. To make the container non-refill-able, there is contemplated a device restraining access to the second valve 56, so that it may not be tampered with.
One example of a restraining device is a disc 84 situa-ted in the immediate proximity of the bottom 64 of the cup-shaped member 58. Said disc is provided with one or more small transverse passages allowing the fluid to be dispensed to flow but preventing tampering with the stopper 5h, whether this be a ball or a disc. Preferably the disc is provided with a side edge having a shoulder 88 which is set in a crown member 90 surrounding the passage 50, to which end the crown member is provided with an outwardly extending annular edge 92.
There is contemplated a sealing cap 94 (Figure 4> having an inwardly dir~octed retaining flange 96 and a weakened portion 98 which would bo broken in an attempt to Force it.
On the one hand the soalinc~ cap 94 provent~; undesired spil-lage and on the other hand guarantees the in'tegr'ity of 'the container and of the Fluid contained.
The description of the pump operation is ornitted because it belongs to the state of t he art. Likewise no reference is made to known a l ements such as the d i p tube cornmun i cat i ng with the bottom of t;he cent,-~ir~er~ and other elements.
The dispensing pump of the invention is in many ways no dif-Fe~r-ent from a conventional pump. Therefore, it is provided with a first group of members to be referred to hereinafter.
In the first place there is a cylinder 2 defining therein a pumping chamber ~1 which is shown in Figure 1 to be in its smallest capacity position. Associated with the cylinder 2 there is a piston 6 adapted to slide within 'the cylinder between a first position (Figure 2) determining the maximum volume of the pumping chamber and a second position (Figure 1) corresponding to the minirnum volume of said chamber 4. It should be noted, however, that the cylinder of the invention has no bottom, to which further reference will be made here-inafter.
In the example shown, the piston 6 is extended by a hollow stem 8 associated with a tube 10 of a dispensing nozzle 12, 'in such a way that the piston 6 and stem 8 are attached to the tube 10 and nozzle 12 and may be moved there by, whereby the upper surface 14 of the nozzle 12 represents an actuator means for the piston. Obviously a force applied to said surface causes the piston 6 to slide within the cylinder 2. A resilient member or spring 16 engages said piston 6 and urges it to 'the said first position.
The association of the hollow stem 8, tube 10 and nozzle 12 forms first communication means between the pumping cham ber 4 and the external environment. This communication is regulated by a valve 18 formed by a valve seat 20 and the stopper 22. No further details of 'the type of valve Shawn are given, since the configuration and special operation thereof are Foreign to the present invention. The valve 18 is urged to the closed position thereoF by a spring 24 and opens in due time to allow the flwid contained in tha purrlping chamber to ba dispensed.
A coupling member 26 allows the pump to be connected to the container 28. Tn the example shown, the mernber 26 is derlorally hood-shaped and is provided with an internal thread 30 adGtptod to engage a thr~ad 32 of the container neck.

It should be noted once again that a simple example of assembly has been described and that the invention comprises other rational solutions appropriate -For the intended pur-pose. The first un it is shown in Figure 2.
The pump is provided also with a second group of members among which there i~~ a passage 50 compr-isod within the com-munication means between the pumping chamber 4 and the interior of the contairmr. Within t~.his passage; there is a valve sEat 52 and the stapper 54 forming thorebotween a second valve 56 regulating the communication between the chamber 4 and the: container.
Pre. Ferably the sari second group also rornprnses a cup-shnped mernber 58 provided wi th the ~:~as~,age 5u ar7d which houses said second valve .'>6, whereby there ns Formed a second _ 5 -unit in which all the members thereof are assembled together in a way making them hardly separable.

Said disc is provided with one or more small transverse passages allowing the fluid to be dispensed to flow but preventing tampering with the stopper 5h, whether this be a ball or a disc. Preferably the disc is provided with a side edge having a shoulder 88 which is set in a crown member 90 surrounding the passage 50, to which end the crown member is provided with an outwardly extending annular edge 92.
There is contemplated a sealing cap 94 (Figure 4> having an inwardly dir~octed retaining flange 96 and a weakened portion 98 which would bo broken in an attempt to Force it.
On the one hand the soalinc~ cap 94 provent~; undesired spil-lage and on the other hand guarantees the in'tegr'ity of 'the container and of the Fluid contained.
The description of the pump operation is ornitted because it belongs to the state of t he art. Likewise no reference is made to known a l ements such as the d i p tube cornmun i cat i ng with the bottom of t;he cent,-~ir~er~ and other elements.
