Description
CLOSURES FOR RECEPTACLES
This invention relates to novel closures for receptacles, and in particular to novel closures which can restrict and or stop the passage of a fluid from a receptacle such as a child's drinking cup.
Receptacles, such as cups, which can contain fluids often have, when used by children particularly babies and young toddlers, lids or closures fitted to them to reduce the amount of fluid that can be spilt from the receptacle when it is shaken or upset. Typically these lids or closures contain a spout with a number of small holes in the top of the spout through which the fluid can pass when a child sucks the cup, but which are intended to restrict the amount of fluid that can leak from the receptacle when it is shaken or upset. In practice the holes are large enough to allow a considerable quantity of fluid to escape from the receptacle when it is shaken or upset.Furthermore, the holes, because of their relatively small size are difficult to clean and they tend to accumulate food and dirt with the attendant risk of endangering the health of the person using the receptacle with this type of closure or lid.
According to the present invention there is provided a closure for a receptacle, said closure comprising a first element and a second element, said first el-ement having an aperture therethrough, said second element having a first portion which is adapted to fit into said aperture, said first portion and said aperture cooperating to form a channel means through the said closure when the said first portion is fitted into the said aperture whereby in use when the closure is fitted onto a receptacle containing a fluid, said fluid can pass out from the receptacle along the channel means.
By closure, for example, is meant without limitation all lids and tops which can be fitted or attached to any receptacle capable of holding a fluid, the closure being adapted to restrict or stop the flow of a fluid from the receptacle to which it is fitted.
By channel means is meant a passage that is created between the inner surface of the aperture of the first element and the outer surface of the first portion of the second element when they are fitted together to form the closure of the present invention. It is thought that flow of fluid along the channel means may be enhanced by capillary flow, and that the longer the channel means the less fluid should escape if the receptacle containing fluid, to which the enclosure is attached, is spilt or shaken.
In one embodiment the said first portion is an essentially round spigot having a "flat" and the aperture of the first element is circular in cross section and is in the form of a hollow spout. In this embodiment the flat extends down at least part of the length of the spigot and in particular all that length of the spigot which fits inside the aperture of the first element. When the first portion is fitted into the aperture of the first element there is created a channel means, being the space between the flat on the first portion and the inside surface of the aperture. The size of the channel means and thus the flow of a fluid can be altered, for example, by altering the width of the flat, by altering the length of the first portion and the hollow spout containing the aperture.
By a "flat" is meant, for example, a flat, ie straight surface which interrupts the otherwise circular cross section of the spigot. A flat whilst preferably having a straight surface can also have, for example, a concave surface or a ridged surface.
The first portion is preferably tapered so that the end nearest the receptacle is wider than the end which is inserted into the said aperture of the first element.
Preferably the aperture of the first element is also tapered so as to match the tapered first portion.
The flat can run along the long axis of the first portion or may, for example, spiral round the outside of the first portion.
The first portion may have more than one flat on it.
These flats may be all of the same size or they may be of different sizes, thus allowing, for example, different rates of fluid flow or, for example, different viscosity of fluids to flow through the channel means created between the different flats on the first portion and the inside surface of the aperture.
The taper on the first portion and the inside surface 0 of the aperture in the spout can be, for example, 2 that is the taper from the bottom to the top of the spigot is 880 0 and not 90 as it would be if the sides of the spigot were parallel. Tapers which are greater or less than 20 may also be used in closures of this invention.
The flats can be about 22 mm long, however flats which are longer or shorter than this may also be employed in closures of the present invention.
The aperture of the first element is preferably located centrally in the first element and is also preferably in the form of a spout extending out from that surface of the first element furthest from the receptacle. In certain embodiments the spout can be continuous with a tube which extends on the other side of the first element so that, for example, this tube can in certain embodiments touch the bottom of the receptacle when the closure is fitted to it.
This tube will suitably fit over the first portion. The aperture is preferably of circular shape with a diameter of about 10 mm, although diameters greater or larger than 10 mm may also be employed.
Suitably the spout containing the aperture will be about 25 mm long although spouts both longer and shorter than this may be employed in embodiments of the present invention.
The spout is preferably located centrally in the first element although spouts located not in the centre of the first element may also be employed in the closures of the present invention.
The first element of the closure of the present invention may be attached to a receptacle in a number of ways including, for example, by press fitting it on over the edges of the receptacle, and by means of a cooperating screw thread arrangement between the first element and the receptacle.
The first element may be made in a wide variety of shapes including, for example, a dome shape, the spout being at the apex of the dome. The outer surface of the first element may be so shaped that it will receive the bottom of another receptacle, which has for example an indentation to accommodate the spout of the first element, so that receptacles and their attached closures of this invention may be stacked one upon the other.
The first elements of the present invention may also be shaped so that a ridge suitably 25 mm high at its highest point, goes round part of or all of the outside of the first element, the ridge being so shaped that a child using a receptacle with a closure of this invention bearing such a ridge, is unable to hurt their eyes with the spout because the ridge hits their face first.
Optionally the spout of the first element can be closed off by means of, for example, a screw-on lid or a push-fit lid which, for example, may be attached to or is separate from the first element.
The second element of the closure of the present invention may be, for example, a separate part or may be attached to or an integral part of a receptacle to which the closure of the invention is fitted. Suitably the second element, when an integral part of a receptacle, comprises a spigot rising from the bottom of the receptacle and extending beyond the top of the receptacle, the spigot having one or more flats on it, the flats being preferably located at the end of the spigot furthest from the bottom of the receptacle.
The second element of the closure also can be in the form of a separate item, for example, comprising a flat disc with a spigot extending from it, the second element being held against the top of the receptacle, and the spigot fitted into the aperture of the first element, by screwing or push fitting the first element, over the second element, onto the top of the receptacle.
In a further embodiment the second element may be retained in a receptacle by engaging with, for example, recesses on the inside of the receptacle, the recesses being so placed that the spigot is left in the correct position to fit the aperture of the first element when it is attached to the receptacle thereby retaining the second element in the receptacle.
In further embodiments the second element of the present invention, when in the form of a separate unit may have, for example, a second spigot with no flats on the surface opposite the spigot with a flat or flats. In this form when the spigot with the flat or flats is in the aperture of the first element fluid can flow through the channel means. However, when the second element is turned upside down and the second spigot without the flats is inserted then no channel means will exist and fluid cannot flow. Thus, in this embodiment the second element can be used to seal a closure of the present invention so that when used on fluid filled receptacles they will prevent fluid loss during travel, for example.
The first elements of the present invention may, as previously disclosed, have a tube continuous with and extending on the other side of the first element to the spout. This tube may suitably be made so that the tube, when fitted over a spigot of the second element, will for part of its circumference extend further down the spigot than a flat on the spigot and for the rest of the circumference not extend as far down the spigot as the bottom of a flat.
The said tube, when so placed that a flat is completely covered, will prevent fluid flowing through the closure because the channel means is sealed off by the tube engaging closely with the spigot around the bottom of the flat, where however a flat on the spigot is not covered by the tube then fluid can flow through the closure because the channel means is not blocked.
Thus by twisting the first element around the second element the longer part of the tube can be made to cover and uncover a flat on the spigot thus closing or opening the channel means. Where the spigot has more than one flat the tube can be so shaped that by appropriate turning of the first element, all, none or some of the resultant channel means can be made open or closed.
In a Specific - embodiment the said tube, having parts extending different lengths down the spigot, may be incorporated totally into the first element and not extending beyond the face of the first element closest to the receptacle.
Appropriate markings or indications may be placed on the outside of the first element and or on the second element so as to indicate if a channel means is open or closed.
The receptacle with which a closure of the present invention is used can suitably be modified by having a recess created in the outer surface of the receptacle, said recess being adapted to allow, for example, a thumb to be inserted which makes the receptacle easier to hold particularly by young children.
In a further embodiment the first portion of the second element can be circular in cross section with no flats and the aperture in the first element will be non-circular in cross section thus creating the channel means when the first portion of the second element is fitted into the aperture of the first element.
In a further embodiment the first portion of the second element may have a flat or flats on it as hereinbefore disclosed and the aperture of the first element is non-circular in cross section thereby creating a channel means when the first portion of the second element is fitted into the aperture of the first element.
A spur may be provided on the underside of the first element cooperable with projections located on the second element to enable a flat on the upper portion of said second element to be alligned with a selected recess in the aperture of the first element.
It is to be appreciated that the embodiments of the first and second elements disclosed above are equally applicable to the next two preceeding embodiments described above.
The closures of the present invention can be used with a wide variety of receptacles which include without limitation, for example, cups, bottles, cans and jugs.
The closures of the present invention can be made from a large number of materials including, for example, plastics such as polyethylene.
The closures of the present invention may also be incorporated into a wide variety of articles including, for example, without limitation children's toys such as houses where the spout is the chimney, perfume bottles and vinegar bottles.
The closures of the present invention have a number of advantages over previously known methods of limiting the flow of fluid from a receptacle. For example, the closures of the present invention are easily cleaned because the first and second elements can be separated and cleaned readily because all the surfaces are smooth with no holes to trap dirt.
Furthermore, it is thought that the channel means created by the first and second elements when fitted together results, when used by a baby or a young child, in the child using a sucking action which is more akin to the sucking action employed with a nipple, and thus is more readily used by the child than known drinking cups with holes therein.
The foregoing and further features of the present invention will be more readily understood from the following description of an embodiment, by way of example thereof, and with reference to the accompanying drawings in which:
Fig. 1 shows an upper portion of a first element of a closure of the present invention;
Fig. 2 shows a perspective view from below of the first element of Fig. 1;
Fig. 3 shows a perspective view of a receptacle with a second element of a closure integrally formed therewith; and
Fig. 4 shows a cross-sectional side view of the receptacle of Fig. 3.
Referring to the drawings, fig. 1 shows an upper portion of a first element 10 of a closure for a child's drinking receptacle 12. The first element 10 has an aperture 14 passing therethrough, and a spout 16, through which the aperture 14 is located, is positioned centrally on the top side 18 of the first element 10.
The spout 16 is shaped so as to allow a child to place his mouth therearound when drinking a fluid contained'in the receptacle 12 for which the first element 10 forms part of the closure of the present invention.
The aperture is circular in cross-section having a diameter of about lOmm but being slightly tapered from bottom to top, the bottom being of a larger diameter to the top The external diameter of the spout 12 is about 17mm, of sufficient diameter as to not be a potential cause of injury to a child's eye. In a not shown embodiment a guard is attached around part of the outside edge of the top side 18 of the first element 10 such than the guard extends above the height of the spout 16 and prevents said spout 16 from contacting a child's eye should the child press its face on the first element 10. The spout may extend about 25mm above the top side 18 of the first element 10.
Fig.2 shows the first element 10 from below. The first element 10 is adapted to locate on a receptacle 12 and in cooperation with a second element 20 enclose a fluid therein. The first element 10 is provided with a rim 22 extending downwards from and around the outer edge of a bottom side 24 of the first element 10 such that the rim 22 affords a push fit of the first element 10 into an upper open end 26 of the receptacle 12.
At a base of the spout 16 adjacent the bottom side 24,the aperture 14 is non-circular having a first and second recess 28, 30 extending up the inner surface of the spout, said recess 28, 30 being of different crosssections.
Figs. 3 and 4 show the receptacle 12 having a second element20 of the closure integrally formed as a part thereof. The second element20 comprises a spigot 34 rising from the base of the receptacle 12 and extending out of the receptacle 12 beyond the upper open-end 26 thereof.
The spigot 34 is circular in cross-section and has located on a first portion 36 thereof a flat 38. The spigot 34 is located centrally in the receptacle 12 and is adapted to cooperate with the first element 10 the first portion 36 thereof locating into the aperture 14 of the first element 10 when the first element 10 is attached to the receptacle 12.
The flat 38 forms a fluid channel means with the inside surface of the aperture 14 through which fluid in the receptacle 12 can flow. The rate of flow of the fluid is governed by the cross-sectional area of channel means so formed. The recesses 28, 30 are provided to allow differing flow rates to be attained by alligning the flat 38 with a selected recess 28, 30.
The length of the flat 38 on the first portion 36 of the spigot 34 is such that when the flat 38 is not alligned with either of the recesses 28, 30 then the channel means is sealed and no fluid can flow. If the receptacle 12 containing fluid is then overturned there will be no leakage of the fluid contained therein. In order to enable fluid flow, the first element 10 is turned in the top of the receptacle 12 until the flat 38 is in allignment with a selected recess 28, 30.
The spigot 34 is tapered, being broader at its base than at the first portion 36, having a taper of about 20 over the length of the spigot 34. This taper matches the taper of the aperture 14 into which it locates
In a not shown embodiment the second element of a closure for a child's drinking receptacle is separate from the receptacle, comprising a flat disc with a spigot extending from it, the second element being placed adjacent the top of the receptacle and fitted into the aperture of the first element by push fitting or a screw means.
Alternatively, the second element may cooperate with recesses in the receptacle to retain the second element in a position to engage the first element on placing said first element on the receptacle.
The spigot of the second element may be provided with more than one flat to allow for selected flow rates of fluid through the channel means formed between the selected flat and the inner surface of the aperture of the first element.
Also, the first element may be attached to the receptacle by a screw arrangement between the first element and the receptacle.
