Definitions

• POUR SPOUT FITMENT This invention relates to a pour spout fitment and to a method of opening a pour spout fitment.
• pour spout fitments are common on many containers of liquids.
• juice cartons sold to the general public are often provided with screw cap arrangements on one top panel of the carton, so that the end user can access the contents of the carton by unscrewing the screw cap and the user can also close the carton in the same manner and store the juice carton in their fridge.
• screw cap arrangements on one top panel of the carton, so that the end user can access the contents of the carton by unscrewing the screw cap and the user can also close the carton in the same manner and store the juice carton in their fridge.
• WO 2010/125354 discloses a pour spout fitment with a tamper evident arrangement.
• a package comprises a container and a pour spout fitment attached thereto, the fitment comprising a pour spout, a closure covering an outer end of the spout, and a tamper evident arrangement attached to the spout or the container, on the one hand, and, more weakly, by at least one frangible bridge to the closure, on the other hand, the arrangement being such that, through opening of the closure, each bridge is broken, but at least one significant portion of the tamper evident arrangement remaining attached to the spout or the container can project laterally outwards noticeably.
• each significant portion is pre-stressed laterally outwardly and is a leg portion extending longitudinally of the spout. In other embodiments, each significant portion is arcuate and extends about the spout.
• the pour spout fitment described in this document while performing effectively as a tamper evident arrangement for a pour spout fitment on a container is relatively complex to manufacture and relies on the tamper evident arrangement breaking from the closure of the fitment at one end while remaining connected to the spout of the fitment at the other end.
• a simpler tamper proof pour spout fitment is desirable.
• a pour spout fitment comprising a pour spout including a knob projecting from the pour spout, and a closure rotatably mounted on the pour spout and including a tab, such that when the closure is rotated relative to the pour spout, the tab on the closure contacts the knob on the pour spout, forcing the tab outwards relative to the pour spout, characterised in that the closure comprises a cap and a tamper evident band connected to the cap, the tamper evident band arranged to separate from the cap when the closure is removed from the pour spout, wherein the tab is mounted on the tamper evident band.
• a method of opening a pour spout fitment comprising a pour spout including a knob projecting from the pour spout and a closure rotatably mounted on the pour spout and including a tab
• the method comprising rotating the closure relative to the pour spout, such that the tab on the closure contacts the knob on the pour spout, forcing the tab outwards relative to the pour spout, characterised in that the closure comprises a cap and a tamper evident band connected to the cap, the tamper evident band arranged to separate from the cap when the closure is removed from the pour spout, wherein the tab is mounted on the tamper evident band.
• the closure comprises a cap and a tamper evident band connected to the cap, the tamper evident band arranged to separate from the cap when the closure is removed from the pour spout, wherein the tab is mounted on the tamper evident band.
• the closure comprises two separate components, a cap and a tamper evident band, which are preferably connected together by a series of bridges around the cap. When the end user opens the closure, the bridges will break, leaving the tamper evident band in place while the cap is removed. The tab is located on the tamper evident band so that the tab remains in place and can be clearly seen in its position after having been forced outwards during the end user opening the closure.
• the pour spout comprises a neck and a flange connected to the neck, wherein the knob is mounted on the neck.
• the pour spout of the fitment can be constructed as a neck on which the closure is mounted at one end of the neck, with a flange being provided at the opposite end of the neck.
• the flange is in plane perpendicular to the longitudinal axis of the neck and is of constant width around the neck.
• the purpose of the flange is to provide a sealing surface that is used to mount the pour spout fitment on a container such as a juice carton.
• the flange can be mounted on the exterior of the container or can be mounted on the interior of the container, with the neck of the pour spout passing through a hole in the container.
• the closure includes a slot, wherein the tab is located within the slot.
• the knob on the pour spout can also be located within the slot of the closure.
• the closure includes a slot that is visible to the end user of the container that has the pour spout fitment attached thereto.
• the slot provides a focal point for the user to clearly see whether the closure has been opened before or not, while also providing a channel for locating the tab.
• the knob can also be located within the same slot, protruding from the pour spout through the slot of the closure, again to be visible to the end user.
• the provision of the slot also means that when the user opens the closure the slot guides the tab over the knob, forcing the tab outwards.
• the pour spout fitment is provided with multiple sets of knobs on the pour spout and tabs on the closure such that when the closure is rotated relative to the pour spout, each tab on the closure contacts a respective knob on the pour spout, forcing each tab outwards relative to the pour spout.
• the tamper evident arrangement can be provided with multiple tab and knob arrangements around the closure, in order to provide multiple visible indicators to the end user, to assist them in determining if a closure has already been opened.
• the multiple sets of knobs on the pour spout and tabs on the closure are evenly spaced around the pour spout fitment, which provides the best visibility to the end user.

• Figure 6 is a perspective view from above of the pour spout fitment of Figure 5 after being opened.
• Figure 1 shows a cross-section through a pour spout fitment 10 for a container.
• the pour spout fitment 10 comprises a pour spout 12 and a closure 1 6 which is rotatably mounted on the pour spout 12.
• the pour spout 12 comprises a neck 20 and a flange 22 connected to the neck 20.
• the closure 1 6 comprises a cap 24 and a tamper evident band 26 connected to the cap 24, the tamper evident band 26 arranged to separate from the cap 24 when the closure 1 6 is removed from the pour spout 12.
• the pour spout fitment 10 is designed to be fitted to a container such as a juice carton.
• the pour spout 12 is provided with an external screw thread 30 and the closure 1 6 is provided with an internal screw thread 32 that mates with the external screw thread 30 of the pour spout 12.
• the user of the container is able to open the container by unscrewing the closure 1 6, which causes the cap 24 to separate from the tamper evident band 26, which are connected together by a small number of bridges that are spaced around the periphery of the cap 24.
• the end user can open and close the cap 24 as many times as the wish after the bridges between the tamper evident band 26 and the cap 24 have been broken.
• the pour spout fitment 10 is provided with an additional tamper evident arrangement, which is described in more detail below.
• the pour spout 12 includes a knob projecting from the pour spout 12, and the closure 1 6, which is rotatably mounted on the pour spout 12, includes a tab 18, such that when the closure 1 6 is rotated relative to the pour spout 12, the tab 18 on the closure 1 6 contacts the knob 14 on the pour spout 12, forcing the tab 18 outwards relative to the pour spout 12.
• This arrangement provides a very clear visual indication of whether the pour spout fitment 10 has been opened or not.
• Figure 2 shows a perspective view from above of the pour spout fitment
• the pour spout fitment 10 is actually provided with multiple sets of knobs 14 on the pour spout 12 and tabs 18 on the closure 1 6 such that when the closure 16 is rotated relative to the pour spout 12, each tab 18 on the closure 1 6 contacts a respective knob 14 on the pour spout 12, forcing each tab 18 outwards relative to the pour spout 12.
• four such knobs 14 and tabs 18 are present, although only two are visible from the view shown in Figure 2.
• a pair of adjacent arrangements is present on opposite sides of the pour spout fitment 10.
• the user When the user opens the pour spout fitment 10 for the first time, they rotate the cap 24 relative to the spout 12, which begins to separate the cap 24 from the tamper evident band 26.
• the tab 18 moves towards the knob 14, since the knob 14 is mounted on the pour spout 12 which is stationary relative to the movement of the cap 24.
• the tab 18 engages the knob 14, the tab 18 is pushed outwards into a visible sticking out position and the tamper evident band 26 will separate entirely from the cap 24, completing the opening process.
• FIG 3 shows the pour spout fitment 10 in the same configuration as that shown in Figure 2, but illustrating a side view of the fitment 10.
• two adjacent tabs 18 can be seen and two respective knobs 14, prior to the opening of the closure 1 6.
• Each tab 18 and knob 14 is located within a respective slot 28 and the slots 28 and tabs 18 are formed as part of the tamper evident band 26 which forms the lower part of the closure 1 6, where the cap 24 forms the upper part of the closure 1 6.
• the tamper evident band 26 and the cap 24 are at this point connected together by bridges.
• each of the four arrangements is identical, being formed from a tab 18 and knob 14 lying within a slot 18 that is present within the tamper evident band 26 of the closure 1 6.
• Each knob 14 protrudes from the tamper evident band 26 through a respective slot 28 and the top of each knob 14 lies flush with the tamper evident band 26, not extending outwardly more than the band 26.
• Figure 4 shows a perspective view of the pour spout fitment 10 after having been opened, in a view similar to Figure 2 (which shows the same view of the fitment 10 before opening of the closure 1 6).
• the cap 24 has been screwed back onto the pour spout 12, but it can be clearly seen that the closure 1 6 has been opened, thereby providing the additional tamper evident arrangement.
• Each of the tabs 18 are sticking out from the tamper evident band 26, which is caused by each of the tabs 18 being pushed outwards by a respective knob 14 when the closure 1 6 is first opened by the end user.
• Figure 5 shows a second embodiment of the pour spout fitment 10, which differs from the embodiment shown in Figures 1 to 4.
• the closure 1 6 further includes a tongue 34 and the knob 14 includes an indent 36 such that when the closure 1 6 is rotated relative to the pour spout 12, the tongue 34 becomes located in the indent 36.
• the tongue 34 of the closure 1 6 extends into the slot 28 of the closure 1 6.
• the tongue 34 is present to ensure that the tamper evident band 26 is not moved after the closure 1 6 has been opened, which could lead to one or more tabs 18 moving into positions where they are less visible to the user.
• each tab 18 there is also a notch 38 present in each tab 18 which is equal and opposite to each of the tongues 34.
• Figure 6 shows this second embodiment of the pour spout fitment, after the closure 1 6 has been opened.
• each tab 18 contacts a respective knob 14, pushing each of the tabs 18 outwards into its visible position pointing outwards.
• the relative movement between the closure 1 6 and the spout 12 results in the tongue 34 of each closure 1 6 locating within a respective indent 36 of a knob 14.
