(54) SQUEEZE BOTTLES AND INSERTS THEREFOR
(71) We, METAL BOX LIMITED, of
Queens House, Forbury Road, Reading
RG1 3JH, Berkshire, a British Company, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to squeeze bottles, this is to say. plastics bottles which may be squeezed by the user to eject the liquid contents through a nozzle in the bottle neck as a jet.
In accordance with the invention there is provided a squeeze bottle which has a screw threaded neck. a closure threaded onto the neck, a wad of resilient, liquid impermeable, material disposed in the closure to close the mouth of the bottle. and an insert engaged in a press-fit manner within the neck. the insert comprising a tubular plug portion in contact with the neck, a diaphragm rooted on the bore of the plug portion, and a nozzle provided with a jet forming orifice and carried by the diaphragm. the diaphragm being deformable to accommodate distortion of the plug portion caused by its engagement within the bottle neck. and furthermore being generally frustoconical and convergent towards the nozzle in a direction awav from the wad of liquid impermeable material whereby to provide a chamber between the diaphragm and said wad and. when the bottle is stood upright after expulsion of contents therefrom in use. to guide strav contents to drain back into the bottle interior through the nozzle orifice.
In order that the invention may be more fully understood an embodiment thereof will now be describcd. by wav of example.
with reference to the accompanying drawings in which Figure I shows a bottle embodving the invention and generally in diametral section; and
Figure 2 is a perspective view of the insert forming part of the bottle of Figure 1;
Referring now to the drawings, a squeeze bottle for bleach is of circular section and centred on an axis XX. It has a blowmoulded plastics body 10 tapering upwardly (as shown) to a cylindrical neck 11 which is externally formed with a conventional screw thread 12.
The free edge 14 of the neck 11 defines the bottle mouth. The mouth is closed by a resilient sealing wad 15 at the closed end of a conventional injection-moulded plastics closure cap 16. The closure cap has a plane closure panel 17 against which the wad is located, and a generally frustoconical peripheral skirt 18 which depends from the closure panel and is internally screwthreaded at a cylindrical portion 19 of its bore to engage the screw threads 12 on the body 10 and thereby hold the cap in position on the body.
The wad 15 has the form of a planar disc.
It is preferably made of a foamed aerosol plastics material the pores of which allow the passage of gas (but not liquid) to ensure equalisation of the pressures inside and outside the bottle when the latter is not in use. Typically the body l() is of high density polyethylene and the closure cap 16 is of polypropylene or high density polyethylene.
As is apparent from Figure 1. the wad 15 does not contact the body 10 directly; instead it performs its sealing function by engagement with the flat annular upper surface 31 of an outwardlv projecting annular flange 2() formed at the top end (as shown) of a generally cylindrical insert 21 (see also Figure 2).This insert is of onepiece construction. being injection-moulded from natural low density polyethylene or like plastics material In addition to the flange 20 the insert comprises a semi-rigid and generally cylindrical plug portion 22 carrying the flange at its top end, a recessed flexible diaphragm 23 which is rooted on the bore of the cylindrical portion 22 part way down the length of the latter, and a nozzle 24 which is carried by the diaphragm 23 on the centre line XX of tie container.
The outside surface of the cylindrical portion 22 is generally cylindrical and dimensioned so as to be an interference fit in the neck 11 of the container body 10 as shown. It is chamfered at its lower end to assist insertion of the insert into the neck during assembly.
The diaphragm 23 is of thin gauge material and rcadily deformable. It is frustoconical but has a liege cone angle so that the nozzle 24 lies within the overall confines of the plug portion 22. The nozzle 24 itself is generally cylindrical, being integrally attached to the inner periphery of the diaphragm at its upper cnd. It is centrally formed with an orifice 25: as shown, the orifice is desirably convcrgent to assist the formation of a coherent jet of liquid when the squeeze bottle is being used.
The body 10 is filled with bleach with the insert 21 removed, whereafter the insert is push-fitted into the body neck 11 to bring the annular lower surface of the insert flange 20 into sealing engagement with the free edge 14 of the body. The closure cap
16, with the scaling wad 15 already in position adjacent its closure panel 17, is then screwed onto the neck until further movement is prevented hy the wad engaging the upper surface of the flange 2í).
The squeeze bottle is then as shown, and ready for despatch and sale. It will particularly be noted that the cap clamps the insert flange 20 firmly between the sealing wad 15 on the one hand and the free edge 14 of the container body on the other. There is thereofore little or no tendency for the bottle to leak. When, in use, the closure cap has been removed and the body 10 is squeezed to expel belach through the nozzle 25, by virtue of the shape of the diaphragm 23 the pressure of bleach exerted on the underside of the diaphragm is referred to the cylindric- al portion 22 of the insert as a radially outward force. The frictional forces between the plug portion 22 and the bore of the bottle neck 11 and by which the insert is held in the bottle are thereby reinforced to reduce the bossibility of dislodgement of the insert.A further advantage of the conical shape of the diaphragm is that after use, when the bottle is stood upright, any bleach left on the upper side of the insert can drain back into the body 10. Furthermore, by virtue of its conical shape and felxibility the diaphragm is readily able to deform so as to allow the plug portion 22 to accommodate itself to the neck 11 into which it is fitted.
Substantial manufacturing variations.
non-circularity etc. of the neck can therefore be tolerated.
When the bottle is not in use but closed, gases generated by the bleach in the bottle can readily be vented from the container through the gas-porous sealing wad 15 around the periphery of the flange 20, the chamber 30 formed above the diaphragm 23 and beneath the sealing wad serving to provide a low resistance distribution path for the gas flow. In a modification of the insert 21 the diaphragm 23 is rooted on the bore of the cylindrical portion 22 at the very top of the latter; its upper surface therefore forms a frustoconical continuation of the upper surface 31 of the flange 2(), rather than being separated from the surface 31 by part of the bore of the cylindrical portion.
