The flange (11) is equipped with: at least one weakening groove (33); sealing contact means (29) with the walls of the bottle (3); and, optionally, reinforcing means (37) adapted to prevent that said flange (11) remains engaged with the bottle (3) when unscrewing the spray pump (1) from the bottle (3).

Description

SEALING DEVICE BETWEEN A SPRAY PUMP AND A BOTTLE CONTAINING A SUBSTANCE TO BE SPRAYED
The present invention refers to an improved sealing device between a spray pump and a bottle containing a substance to be sprayed, and in particular it refers to a so-called "trigger" applied under pressure on bottle mouths with a coupling of the bayonet type.
Various types of sealing devices are known in the art and they allow connecting spray pumps to diffuse a liquid product to the vessel containing the product itself. Through them, the pump body is placed on the bottle mouth and then, through a combined pressure action towards the bottle bottom and a rotation around the axis thereof, the pump is secured to the bottle through a coupling of the bayonet type. Such arrangement is efficient since it allows, once the liquid contained in the vessel runs out, to unscrew and remove the spray pump and to replace the empty bottle with a full one without having to purchase again the whole device.
The most common problem with these sealing devices for pumps and bottles is obviously the one related to liquid leakages, for which it is necessary to provide an arrangement of the flange type. Such arrangement is provided by two prior art documents, that will be briefly described below.
In particular, document US-A-3, 080, 993 to Livingstone discloses a coupling equipped with a toggle gasket that, through different embodiments, allows obtaining an airtight seal closure by strictly adhering to the bottle walls once having been pressed close.
Moreover, document US-A-3, 244 , 308 to Esposito discloses a coupling of the type mentioned in the previous document, wherein the gasket is further equipped with weakening grooves for a better flexure thereof when closing.
These gaskets however are not wholly satisfactory and shows the following problems: in case ovalized walls, scorings, blowings, seizures or other moulding defects are present in the bottle, such gaskets are not able to perfectly adhere to the bottle walls and do not guarantee a perfect seal; in order to assemble them, it is necessary to apply a high axial load, indeed for the purpose for which they have been prearranged, that is guaranteeing, in addition to a seal, an efficient closure for a long time; the seal of the flange in document US-A-
3,244,308 is not perfect, since it is only guaranteed by the coupling between bottle walls and flange through the mere force exerted by the toggle flange; the flange in document US-A-3, 080, 993, moreover, in order to guarantee a better unmovability, comes in a sense to be engaged into the bottle, exceeding a point above which it is abutted to the vessel: this is not useful for the bottles of the present invention, where instead the flange must be able to be easily detached from the bottle walls when replacing the bottle itself.
Object of the present invention is solving the above prior art problems, providing an improved sealing device equipped with a new type of flange that allows simultaneously obtaining an optimum seal even when there are manufacturing defects in the bottle walls; an installation with low axial load when fitting the flange onto the bottle; and a high resiliency when disassembling the pump body from the bottle itself.
The above and other objects and advantages of the invention, as will appear from the following description, are obtained through a sealing device as claimed in Claims 1 and 2. Preferred and non- trivial embodiments of the present invention are disclosed in the dependent Claims.
The present invention will be better described by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed drawings, in which:
Figure 1 is a sectional view of the sealing device of the present invention in the final assembled position;
Figure 2 is a partially sectional view of
Fig. 1 showing a first assembling step of the pump on the bottle;
Figure 3 is a partially sectional view showing a second final assembling step of the pump on the bottle;
Figures 4 to 6 are respectively a sectional view during rest, a sectional view when assembling and a perspective view of another embodiment of the flange included in the sealing device of the present invention;
Figures 7 to 9 are respectively a sectional view during rest, a sectional view when assembling and a perspective view of another embodiment of the flange included in the sealing device of the present invention;
Figures 10 to 12 are respectively a sectional view during rest, a sectional view when assembling and a perspective view of another embodiment of the flange included in the sealing device of the present invention;
Figures 13 to 15 are respectively a sectional view, a side view and a perspective view of the flange shown in Figs. 2 and 3; and
Figures 16 to 18 are respectively a sectional view, a sectional view in an assembled condition and a perspective view of a further preferred embodiment of the sealing device of the invention. With reference to Fig. 1, a sectional view is shown of the product to which the sealing device of the present invention is applied, comprising a spray pump unit 1 to spray a liquid product contained inside a bottle or vessel 3, equipped with a bayonet-type coupling, that allows connecting the mouth 7 of the bottle 3 to a suitable seat 9 of the spray pump body 1 through the simultaneous operations of pressing the two components one towards the other and rotating the component themselves around their axis. The spray pump unit 1 and its components are well known in the art and will not be further disclosed therein, as well as the bayonet-type coupling, that is the subject of European Patent Application No. 98200722.1 assigned to the same Applicant of the present Application.
In order to guarantee an optimum seal and prevent the leakage of the product contained inside the bottle 3 in the sealing device, it is provided to insert therein a sealing flange 11 whose shape is substantially circular, that is fitted onto the frame 13 of the pump unit 1 and that is then assembled on the coupling as will be better described hereinbelow. The flange 11 has been equipped with a set of features, in order to make it able to be applied to a product of this type, where it is necessary to perform a replacement operation for the bottle 3 when the product therein runs out. In order to better understand the breadth of such features, the assembling steps of pump 1 on bottle 3 will first be described, with particular reference to Figs. 2 and 3. In a first step, as shown in Fig. 2, after having fitted the flange 11 onto the frame 13, the pump unit 1 is placed on the mouth 7, by fitting the upper part 21 of the mouth 7 into a suitable external groove 23 obtained by shaping the flange 11. Fig. 3 shows the second final assembling step, wherein the pump unit 1 is pushed towards the bottle 3 together with a rotation around their axis. This push also allows starting to flex the flange 11, that is made of a suitable resilient material such as average-density polyethylene. Finally, the coupling between pump 1 and bottle 3 is completed by snapping a suitable tooth 25 into the seat 9 in a recess 27 of the mouth 7. The flange 11 is in its working position, completely pushed in contact with the walls of the bottle 3.
In order to first guarantee an optimum sealing force of the flange 11, this one has been further equipped with sealing contact means 29, that, in the different embodiments shown, are composed of bumps with different types, shapes and sizes, that allow exerting a higher pressure force against the walls of bottle 3. Moreover, the seal occurs in particular points (for example the one designed with 31 in Figs. 2 and 3) where negative impairments due to manufacturing defects of the bottle 3 are more evident, such as for example ovalized walls, scorings, blowings, seizures or other moulding defects.
In spite of the optimum seal, the flange 11 of the invention must be able to guarantee a low axial insertion load, in order not to make assembling operations harsher, both when a user manually operates, and automatically when manufacturing the product. For such purpose, the flange 11 has been equipped with at least one weakening groove 33, obtained next to the central part 35 thereof in contact with the frame 13: such weakening groove 33, by making assembling operations simpler, allows easily reaching the final working position (as shown in Fig. 3) .
Moreover, the flange 11 of the present invention must be able to easily go back to its rest position (as in Fig. 2) when the pump unit 1 is unscrewed from the bottle 3: therefore, the flange 11 must not be anchored to the bottle 3 walls when it is assembled, as occurs for the similar prior art flanges. In order to avoid that the flange 11 exceeds the point in which it is no more able to go back to its starting position by its own force, reinforcing means 37 have been provided, that, when assembling, abut against the walls of the bottle 3 and prevent a further movement of the flange 11 inside the bottle 3 itself. As shown in Figs. 2 and 3, such reinforcing means 37 are preferably composed of at least one wing (in the embodiment shown, the wings are four) , whose cross section is preferably shaped as a triangle: the operation of wings 37 during the final assembling step can be better seen in Figs. 2 and 3. The flange 11 of the present invention can also be realized with an arrangement in which such reinforcing means 37 are not provided.
Finally, stop notches 39 are provided, obtained along the whole circumference of flange 11, that allow discriminating the sealing area, because they work in an area where the bottle shows the best finishings.
With reference to Fig.s 16 to 18, a further preferred embodiment of the flange 11 of the invention is shown, suitable to be applied to a device that allows spraying the contained liquid even if the containment bottle is overturned. Due to this reason and for this purpose, the flange 11 is further equipped with a small lip 41 that allows performing a permanent seal on the stem 43 of the pumping unit supporting the flange 11, in order to guarantee a better seal against the leakage of contained liquid. In order to allow spraying with an overturned bottle 3, it is further necessary to provide a vent hole 45 obtained on the flange 11, on such vent hole 45 a membrane 47 being welded in order to allow air but not liquid to go out.
Some embodiments of the invention have been described, but obviously they are prone to further modifications and variations within the same inventive idea. This clearly appears in Figs. 4 to 12, that show three embodiments of the flange 11 of the invention, in which three different geometric sectional typologies are exploited as regards the flange 11 to guarantee an adequate pressure and sealing force that compensates for all possible ovalizations of the bottle 3, due to the preferential sealing area provided by the respective bumps 29.
In particular, Figs. 4 to 6 show an embodiment which works on the material resiliency in addition to its geometry, and which, theoretically, can work with an excursion with a bigger diameter. Instead, Figs. 7 to 9 show an embodiment further equipped with a plurality of ribs 43 that depart as rays from the central part 35 of the flange 11: in such case, there is a toggle with shortened levers, whose excursion is more limited but that has a greater stiffness, since the levers are less subjected to a permanent set; finally, the ribs 43 dampen part of the load.
Figs. 10 to 12 show a further embodiment according to the invention, wherein the flange 11 has weakenings to make its rotation easier; the levers are longer to improve the fitting, providing a greater excursion between starting diameter and final diameter; moreover, the external undercut improves crimping on the bottle 3 to guarantee the disassembly of the relaxed flange.
Finally, Figs. 13 to 15 show in detail the preferred configuration of the flange 11 with the wings 37 with a triangular section, already shown during the assembling steps in Figs. 2 and 3.
Obviously, the weakening grooves 33 and the reinforcing means 37 can be provided in numbers greater than one, should particular application conditions so require.
