In the preferred forms of the present invention the components are moulded as single unitary items although in some other much less preferred forms one or more of the components can be machined and/or fabricated in some way. That however detracts from the low cost prospect of a simplified jigged or robotic assembly of a closure structure capable of being removed as a whole from a screw threaded complementary container and/or being applied thereto.
In the case of sales of an empty container, the closure assembly would be attached to the assembly and can be removed for filling by rotation of the assembly as a whole or by obtaining a manual purchase on the peripheral region of the first component only.
The other sales option of course is to provide a filled container preferably sealed in some way a foil or other such closure under an assembly of an embodiment of the present invention.
Preferably a plastics material is to be used for each component of each embodiment of the assembly. Possible plastics can be selected from the group consisting of polypropylene (PP), polyethylene (PE) and high density polyethylene (HDPE).
Each component can be injection moulded to shape in a number of different ways.
Each requires a two part die and, depending on the form and the material, optionally inserts whereby a removal technique can be optimised for the two halves of the die.
For instance the component of Figure 40 in HDPE may need five inserts shared between the two halves of the die.
Preferably multicavily moulding is utilised for economy e.g. from 2 cavity upwards.
Two series of embodiments will now be described, a first series where the nipple does not rotate with the twist ring and a second series where the nipple does rotate with the twist ring.
Embodiment 1(Usually Larger than Embodiment 2) The embodiment of Figures 1 to 31 is an assemblage of the three components shown therein. Here the nipple 10 does not rotate with the ring or twist member 13 -it merely rises and lowers.
A preferred choice of materials for this embodiment is:

Embodiment 1(Usually Larger than Embodiment 2) The embodiment of Figures 1 to 31 is an assemblage of the three components shown therein. Here the nipple 10 does not rotate with the ring or twist member 13 -it merely rises and lowers.
A preferred choice of materials for this embodiment is:
- nipple or mouth piece 10 - HDPE
- Twist section 13 - PP
- base l - HDPE
As can be seen there is a first component 1 (see Figure 9), of the base, which has a periphery 2 available for manual grip or purchase for removal of that threaded component, if desired, when assembled. That thread 3 can best be seen in Figure 15 and 16.
The columnar form 4 provides an entrance 5 for liquid from an engaged container and, via a passageway 6, out of an outlet 7 which is below the closure portion 8 which is, as shown in Figure 1 and 7, able to occlude the dispensing opening 9 of a second component or top 10.
The top 10, apart from its spout type form, includes a thread or thread following formation 11 adapted to be engaged by the thread or thread follower 12 (see Figure 25) of the third component or twist ring 13.
As shown the component 10 (the top) can move between the conditions shown in the cross sections of Figures 7 and 8 under the rotational action of the captive twist ring 13 held captive to the first component 1 by a clip fit bead into groove engagement at 14 (see Figure 7).
As best can be seen from the cross sections of Figures 7 and 8, whilst liquids can enter the passageway 6, pass via the outlet 7 into the chamber 15, other liquid movement is prevented and the liquid cannot exit the opening 9 owing to that being occluded by the closure portion 8.
Other features include the provisioii of sealing rings 16 in the first component 1, and an arrangement whereby the surface 17 of the first component 1 and the surface 18 of the twist ring seals in a substantially fluid type manner against the region 19 of the second component.
Provision can be made for restricting the amount of rotation required for an opening and/or closure cycle and indeed some bump engagement can be provided to that end.
Another feature of interest is the provision of gaps 20 in the partitioned wall of the first component into which members 21 of the second component (see Figure 18) are slidable so as to be restricted against relative motion with respect to the first component so that the affect of the thread inter-engagement with the twist ring is an axial raising and lowering as depicted in the drawings rather than any other movement.
Embodiment lA
If the nipple of the first embodiment (i.e. Figures 1 to 31) is a deemed "swallowable"
component, retention can be fiufilier enhanced by further snap in interengagements. See Figure 79 and 80 as of a variation of the first embodiment having two snap in interengagements 44 and 45 between base 46 and twist ring 47 (rather than just one) to increase the pull off force required.
There are with at least this embodiment, three nipple to base or twist ring sealing surface interactions to prevent flow back, even when open, thereby to waterproof with assembly. These are at see Figures 79 and 80.
Embodiment 1B
The embodiment of Figures 63 through 77 is also a modification of the first embodiment shown in Figures 1 to 32. Similar materials are used for this embodiment as for that embodiment.
A feature of this enllanced assembly with its componentry as depicted is the helix extension, the addition of feet, the angular nature of the top of the component of Figures 76 and 77, the additional stop added to the component of Figures 71 and 72 and the additional stops and support ribs added to the components of Figures 73 to 75.
Slots 40 in the slotted radial wall 39 of the base 37 and the ribs 41 in nipple merely are to restrict the nipple to ride up/down without rotation relative to the base.
Extra ribs 38 of base 37 are outstands to maintain the shape of the skirt of the nipple to prevent disengagement.
The feet 42 provide extra material below the grooved thread lead in 43.
The rotational stops 36 act on interacting stops such as 34 of ring 35. The stops 34 are preferably designed to click over lesser formations adjacent a stop 36 thereby to provide a click open/click close feature.
- Twist section 13 - PP
- base l - HDPE
As can be seen there is a first component 1 (see Figure 9), of the base, which has a periphery 2 available for manual grip or purchase for removal of that threaded component, if desired, when assembled. That thread 3 can best be seen in Figure 15 and 16.
The columnar form 4 provides an entrance 5 for liquid from an engaged container and, via a passageway 6, out of an outlet 7 which is below the closure portion 8 which is, as shown in Figure 1 and 7, able to occlude the dispensing opening 9 of a second component or top 10.
The top 10, apart from its spout type form, includes a thread or thread following formation 11 adapted to be engaged by the thread or thread follower 12 (see Figure 25) of the third component or twist ring 13.
As shown the component 10 (the top) can move between the conditions shown in the cross sections of Figures 7 and 8 under the rotational action of the captive twist ring 13 held captive to the first component 1 by a clip fit bead into groove engagement at 14 (see Figure 7).
As best can be seen from the cross sections of Figures 7 and 8, whilst liquids can enter the passageway 6, pass via the outlet 7 into the chamber 15, other liquid movement is prevented and the liquid cannot exit the opening 9 owing to that being occluded by the closure portion 8.

component, retention can be fiufilier enhanced by further snap in interengagements. See Figure 79 and 80 as of a variation of the first embodiment having two snap in interengagements 44 and 45 between base 46 and twist ring 47 (rather than just one) to increase the pull off force required.
There are with at least this embodiment, three nipple to base or twist ring sealing surface interactions to prevent flow back, even when open, thereby to waterproof with assembly. These are at see Figures 79 and 80.
Embodiment 1B
The embodiment of Figures 63 through 77 is also a modification of the first embodiment shown in Figures 1 to 32. Similar materials are used for this embodiment as for that embodiment.
A feature of this enllanced assembly with its componentry as depicted is the helix extension, the addition of feet, the angular nature of the top of the component of Figures 76 and 77, the additional stop added to the component of Figures 71 and 72 and the additional stops and support ribs added to the components of Figures 73 to 75.

Extra ribs 38 of base 37 are outstands to maintain the shape of the skirt of the nipple to prevent disengagement.
The feet 42 provide extra material below the grooved thread lead in 43.
The rotational stops 36 act on interacting stops such as 34 of ring 35. The stops 34 are preferably designed to click over lesser formations adjacent a stop 36 thereby to provide a click open/click close feature.
Embodiment 2 (Usually smaller than Embodiment 1) The embodiment of Figures 32 through 60 is different but is of the same three essential components and preferably after clip fitting of the third member to the first member, it can be handled as a unit. Here the nipple turns with the ring.
A preferred choice of materials for this embodiment is:
- nipple or mouth piece 27 - HDPE
- Twist section.. . - PP
- base 22 - HDPE
Here the arrangement involves a first member 22 with its columnar upstand 23 about an open passage 26 having its outlet or outlets 24 preferably below a closure portion 25 which is to occlude the dispensing opening 26 of the second component or top. As can be seen by reference to Figure 46 the colunmar structure or form 23 includes a thread or thread following arrangement 47. This thread arrangement 47 is to engage the thread or thread follower 28 shown in the component 27 (see Figure 53). The component 27 is held against rotation by its key ways or grooves 29 riding on a complerrientary form 30 (see Figure 54) of the twist ring 31. These anti-rotation guideways and guide followers can be plural and can differ i.e. male to female and female to male to ensure proper location.
Shown also in the component 31 (see Figure 55) is a formation 32 the function of which is to abut the upstands 33 of-the first component (see Figure 40) thereby to restrict twisting movement between the open and closed conditions to about 180 . Such an arrangement however is not mandatory.
Such rotation restriction is preferred as it can be used to ensure interengagement of formations 28 in grooves 47 prevents the once assembled embodiment from having its nipple 27 pulled free of the base.
Embodiment 2a The arrangement of Embodiment 2 can be varied.
A preferred choice of materials for this embodiment is:
- nipple or mouth piece 27 - HDPE
- Twist section.. . - PP
- base 22 - HDPE
Here the arrangement involves a first member 22 with its columnar upstand 23 about an open passage 26 having its outlet or outlets 24 preferably below a closure portion 25 which is to occlude the dispensing opening 26 of the second component or top. As can be seen by reference to Figure 46 the colunmar structure or form 23 includes a thread or thread following arrangement 47. This thread arrangement 47 is to engage the thread or thread follower 28 shown in the component 27 (see Figure 53). The component 27 is held against rotation by its key ways or grooves 29 riding on a complerrientary form 30 (see Figure 54) of the twist ring 31. These anti-rotation guideways and guide followers can be plural and can differ i.e. male to female and female to male to ensure proper location.
Shown also in the component 31 (see Figure 55) is a formation 32 the function of which is to abut the upstands 33 of-the first component (see Figure 40) thereby to restrict twisting movement between the open and closed conditions to about 180 . Such an arrangement however is not mandatory.
Such rotation restriction is preferred as it can be used to ensure interengagement of formations 28 in grooves 47 prevents the once assembled embodiment from having its nipple 27 pulled free of the base.
Embodiment 2a The arrangement of Embodiment 2 can be varied.
The ring or twist part of the Figure 32 to 62 embodiment can be kept within twist limits if desired by an additional interaction (i.e. one both inside and outside of the stop formation(s) of the base) thereby to reduce any prospect of ride over of a single interaction.
See Figures 81 to 83.
Now twist ring 48 has:
- radially larger stop/vane 49outside of stop formation, i.e. 50 of base 51 - radially smaller stop/vane 52 inside of stop formation, i.e. 53 of base 51.
Now also a bump to close/open feature is provided at each stop formation 54/55 for click close/click open. -Limit on rotation prevents nipple from coming out - only assembles one way.
Persons skilled in the art will appreciate how the embodiments depicted have been provided with a bump to stop feature on opening and a bump to stop feature on closing. In each case the bump provides a measure of hold against a change of condition until the bump is overwhelmed by a reverse rotation of the third component.
Figures 61 and 62 show opened and closed respectively a screw thread connected assembly of Embodiment 1. Similarly will be the bottle/container to capping assembly of any of the other embodiments.
