Description
3L~3i~
The present invention relates to closures for contalners and particularly to dispensing closures by which the contents of a container with which the closure is used is dispensed at a controlled rate.
Dispensing closures frequently are used with containers for packaging a wide variety of products, usually liquids ranging widely in viscosity from edibles such as syrup and ~atsup to non-edibles such as liquid detergents and shampoos. It frequently is necessary for manufacturers who package several products having different viscosities to carry inventory of dispensing closures of different sizes to accommodate packaging of the different products. It would be highly desirable in such instances to have a single dispensing closure that could accommodate a variety of products of different viscosities by offering the possibili-ty of varying the orifice or selecting an orifice of a particular size. Such a closure also could offer the consumer or purchaser a choice of a dispensing opening which is a larger or smaller than the one recommended by the manu-facturer.
The dispensing closure contemplated by thepresent invention includes a closure body adapted for attachmen~ to a container and is formed with an opening of a predetermined size radially offset from the axis of the body ; to form a passage for the contents of the container. The opening is closed by a lid or cap member rotatably connected to the body. The lid member is provided with a plurality of apertures having the axes radially offset relative to the axis of the lid member a distance equal to the distarlce of ~ ~, , ... .
$
the opening in the closure body with the plurality of apertures progressively diminishing in size to provide a range of openings so that ro-tation of the lid member relative to the body member brings a selected one of the apertures into alignment with the openins in the body member to permit dispensing of the contents of the container.
A preferred embodiment of the invention is illus-trated in the drawings in which:
Figure 1 is a cross-sectional view of a dispensing closure assembly embodying the invention;
Figure 2 is a top plan view of a closure body forming one element of a dispensing closure assembly;
Figure 3 is a bottom view of a lid member forming another element of the closure assembly; and Figure 4 is an exploded perspective view of the two parts making up the dispensing closure of the present invention.
The adjustable dispensing closure embodying the present invention is designated generally at 10 and includes a closure body 12 and a cap member 14. The closure body 12 and cap member 14 are generally cylindrical and have the same diameter.
The closure body 12 is generally cup-shaped with a top wall 16 and a depending cylindrical skirt 18. The top ball 16 is provided with a dispensin~ opening 20 through which the contents of the container with which the closure 10 is used is dispensed. The interior wall of the skirt 18 is provided with threads 22 by which the closure 10 may be attached to a container ~not shown). Other forms of fasten-ing means such a snap beads or adhesive may also be used to permanently attach the closure 10 to the container.
~.
The underside of the top wall 16 is provided with an annular seal 2 which engages the top of the container opening to ensure that the contents of the container must pass through the opening 20.
The cap member 14 has a generally disc-shaped top with a depending skirt portion 26 having the same perimeter as -the skirt 18 of the closure body 120 In the assembled condition of the closure body 12 and cap 14 as seen in Fig. 2, the respective skirts 18 and 26 are.in alignment with each other.
The body 12 and cap 14 are held in reIatively rotatable relationship to each other by an annular be.ad 28 formed on the unders~de of the cap member 14 and a comple-mentary annular bead 30 formed on the top of the wall 16 of the closure body 12. The annular bead 28 forms a radially outwardly facing groove 32 which receives the outer lip of the annular bead 30. Similarly, the annular bead 30 forms a radially inwardly facing groove 34 which receives the outer lip of the annular bead 28. The interlocking action of the annular bead 28 and 30 serves to maintain the closure body 12 and cap 14 in axially fixed relationship to each other and at the same time permits free rotation of the cap 14 relative to the body 12 by maintaining the skirt 26 axially spaced a slight amount from a shoulder 38 formed at the upper end of the skirt 18 and by maintaining a slight radial spacing between the inner surface of the skirt 26 and the annular bead 30 o~ closure body 12. Retention of the beads 28 and 30 in interlocking relationship with each other is further facilitated by an annular guide bead 36 seen in Figs. 1 and 2 and formed on the top of the wall 16.
. -- 3 --The cap member 14 is provided with a plurality of apertures 41, 42, 43, 44 and 45. The largest of the aper-tures 41 corresponds generally in size to the opening 20 in the closure body 12 and the remaining openings progressively decrease in size to opening 45 which is the smallest of the openings. The opening 20 in the top wall 16 is surrounded by a collar 48 which has an annular seating surface 50 surrounding the opening. The seating surface 50 is comple-mentary to a raised seating surface 52 which surrounds each of the openings.
The opening 20 is offset a predetermined radial distance from the axis of the closure body 12 and similarly, the apertures 41 through 45 are disposed on an arc having a radius equal to the same predetermined distance so that upon rotation of the cap 14, selected ones of the openings or apertures come into alignment with the opening 20. A
portion of the same arc indicated generally at 54 which is disposed between the largest of the openings 41 and the smallest of the openings 45 can be brought into alignment with the opening 20 to maintain it in a closed condition preventing the dispensing of the contents of the container with which the closure 10 is used.
After a container with which the closure 10 is used has been filled with its intended contents, the closure 10 is used by rotating the cap member 14 relative to the stationary closure body 12 ~o bring a selected one of the apertures 41 through 45 into alignment with the opening 20 and the closure body 12. Upon selecting one of the apertures, the closure body 12 and cap 1~ are held in the selected relationship by the coaction of the seating sur~ace 52 surrounding the selected opening and the seat S0 in the collar 48.
