Description

RESEALABLE BOTTLE CAP WITH PUSH-PULL CLOSURE This invention relates to a resealable bottle cap with a push-pull closure and in particular to tamper indicating closures for containers, such as blow moulded plastics bottles, such as used by sport's figures as water bottles and/or beverage containers.
Prior closures of this type may be seen in U.S. Patent Nos. 3,902,621, 4,469,253, 4,500,016, 4,561,553, 4,589,561, 4,801,032 and 4,948,003.
The present cap in part resembles the tamper-evident closure of U.S. patent 4,589,561.
According to the present invention, there is provided a resilient, resealable bottle cap for a bottle having a neck with dual bottle cap retaining means on the exterior of the neck, said cap having an annular flange depending from a cap top for surrounding the bottle neck, said flange having means for engaging said cap retaining means, and an internal annular groove, the depending flange below said groove defining a tear skirt with a pull tab; there being a pour spout on said top communicating with an opening in said top, said pour spout having an apertured secondary top thereon and means on said secondary top positioning a plug in spaced relation to said secondary top and its aperture, and there being a top cap movably disposed on said spout and having an opening registering with said plug to form a closure when said top cap is in a first position, said top cap including a ring and a plurality of frangible elements integrally connecting said ring with another part of said top cap in said first position; and a flange on said spout retaining said ring in said first position when said top cap is moved away from said first position to a second position to locate said opening in said top cap in spaced relation to said plug.
The invention also extends to a combination of the cap and a bottle on which it is fitted.
For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which:- Figure 1 is a vertical section through a portion of a resealable bottle cap with a push-pull top portion thereof in closed and sealed position; Figure 2 is a view similar to Figure 1 with the push-pull top portion shown in open position; Figure 3 is a side view of the bottle cap; Figure 4 is a plan view of the bottle cap; Figure 5 is a perspective view of the bottle cap with a portion of a tear skirt removed; and Figure 6 is a perspective view of a top cap portion of the cap prior to assembly on the remainder of the cap.
Referring firstly to Figure 5, a resealable bottle cap has a push-pull closure positioned thereon and includes a top portion 10 with a depending annular flange of different diameters, one of which forms a relatively short first portion 11 and the other forms a larger diameter portion 12.
An out-turned flange 13 is formed over most of the lower edge of the portion 12 and a pull tab 14 is provided on the portion 12 in the area between the ends of the out-turned flange 13.
The portion 12 is provided with an annular area of weakness comprising an internal tear groove 15 which enables the portion 12 to be removed when the tear tab 14 is held and moved outwardly and around the resealable bottle cap.
In Figure 1, it will be seen that an opening 16 is formed centrally of the top 10 of the cap and that an upstanding cylindrical pour spout 17 is positioned in registry with the opening 16, the upper end of the spout 17 having a secondary top portion 18 thereon which is apertured at 19.
A plug 20 is positioned on the secondary top 18 in spaced relation to the aperture 19 by a plurality of circumferentially-spaced, angularly arranged legs 21.
A push-pull top cap 22 is positioned on the spout 17 and comprises a top portion 23 having a central opening 24 therein which registers with the plug 20 to form a closure when the top portion 23 is in the position illustrated in Figure 1 and resting on the secondary top 18 of the spout 17. The top cap 22 has a depending cylindrical body 25 and is connected by a plurality of frangible elements 26 on its lower edge with a ring 27. The ring 27 has an inturned annular flange 28 thereon which slidably engages with the exterior of the pour spout 17. The body 25 of the top cap 22 has two inturned annular flanges 29 which also slidably engage the outer surface of the pour spout 17.There are two annular flanges 31 and 32 respectively, formed on the exterior of the pour spout 17, the flange 31 being oppositely disposed with respect to the secondary top 18 and the flange 32 being spaced therebelow and above the top 10 of the bottle cap so that reciprocating movement of the push-pull top cap 22 is limited.
In the assembled form illustrated in Figure 1, the integral ring 27 joined by the frangible elements 26 to the cylindrical body 25 of the top cap 22 is incapable of moving upwardly due to the inter-engagement of the flange 28 thereon with the flange 32 on the spout 17, whilst the cylindrical body 25 of the top cap 22 is incapable of vertical movement such as necessary to move the apertured top 23 thereof above the plug 20 until sufficient force is applied to the top cap 22 to break the frangible elements 26, whereby the top cap 22 can move to the position illustrated in Figure 2 wherein the opening 24 therein moves upwardly and away from the plug 20. The flanges 29 on the cylindrical body 25 of the top cap 22 cannot move above the flange 31 on the secondary top 18 of the spout 17 so that the push-pull top cap of the bottle cap is childsafe as it is not removable therefrom.
Figure 3 shows the resealable bottle cap in its initial assembled condition and it will be seen that there is an area of weakness 15A extending between the lower edge of the larger portion 12 and the tear groove 15.
The portion 12 of the depending flange engages a neck finish 35 of a water bottle 36 (Figure 1) or the like and is provided with two configurations for engaging, matching or registering with configurations on the neck finish.
These comprise an internal annular flange 37 on the lower inner edge of the flange portion 11 of the bottle cap, which is in opposed relation to the conventional depending sealing flange 33 of such caps, and an annular groove 34 in the larger diameter flange portion 12. The blow moulded water bottle 36 or similar containers having an appropriately shaped neck finish 35 including annular ribs 38 and 39 on their outer surfaces will accordingly register with the flange 37 and the groove 34 of the present cap.
It will thus be seen that the present resealable bottle cap with a push-pull closure forms an attractive and very practical closure for a water bottle such as used in various sports such as bicycle races and the like, in that the bottles which are initially filled and sealed by the application of the resealable bottle cap will retain the bottle cap in position due to the registering configurations in the depending annular flanges of the portion of the cap engaging the water bottle finish and at the same time provide a tamper-indicating sealed closure with respect to the upstanding cylindrical pour spout which must be forcibly opened by moving the push-pull top cap 22 upwardly so as to break the frangible elements 26 to open the aperture 19 therein and permit the contents of the water bottle to be used. At such time as the water bottle 36 is empty, it may be refilled by using the tear tab 14 to remove the major portion of the larger flange portion 12 from the bottle cap, which can then be removed by forcibly disengaging the inturned annular flange 37 from a matching configuration on the water bottle neck finish. This latter feature permits the bottle cap to be repositioned on the refilled water bottle where it holds tightly and permits the push-pull top cap 22 to be opened and closed in the same manner as was provided by the original complete resealable bottle cap assembly.
The cap may be formed of a resilient, moulded plastics material such as polyethylene.
