Definitions

• This invention relates to a pour spout fitment, a package including a pour spout, and a method of inspecting the package for evidence of tampering.
• the commonest tamper- evident devices incorporated in pour spout fitments are such that, after opening of the fitment and re-closing it, the fact that the bridges have been broken is difficult for a consumer to detect.
• a pour spout fitment for attachment to an outside surface of a wall of a container and comprising a pour spout bounding a pouring mouth, a cover closing said pouring mouth, and a device in said pour spout whereby a hole can be formed through a zone of said wall to permit pouring of a flowable content of said container from said pour spout, a portion of said cover or of said spout being sufficiently transparent and so situated that a consumer can conclude without opening of said cover, but by inspection through said portion from outside said container, whether or not said hole has been formed.
• a package comprising: -
• a pour spout attached to a wall of said container and bounding a pouring mouth, a cover closing said pouring mouth, and a device in said pour spout whereby a hole can be formed through a zone of said wall to permit pouring of a flowable content of said container from said pour spout, a portion of said cover or of said spout being sufficiently transparent and so situated that a consumer can conclude, without opening said cover, but by inspection through said portion from outside said container, whether or not said hole has been formed.
• a method comprising concluding whether a hole has been formed through a wall of a sealed package at a zone beneath a closure including a pour spout, by visual inspection through material of a portion of said closure .
• the invention is applicable to, in particular, a pour spout with a screw cap in which turning of the screw cap causes piercing of the container wall to form the through
• the whole of the screw cap is advantageously made of one-and-the same material which is itself is sufficiently transparent.
• the invention is also applicable to a pour spout with a hatch-type cover, particularly with a hingedly mounted hatch cover, in which case the whole of the hatch cover is advantageously made of the sufficiently transparent material.
• the sufficiently transparent material may be high density polyethylene, although polypropylene is preferable because it can be more transparent than high density polyethylene following injection-moulding.
• Figure 1 is an exploded view, partly in .axial section, of a screw-capped pour spout fitment
• Figure 2 is a fragmentary view, partly in axial section, of the fitment welded or otherwise adhered to an external surface of a fragmentarily shown wall of a carton.
• the pour spout fitment 2 consists of a flanged pour spout 4, a screw cap 6 and an annular, hole-piercing device 8.
• the spout 4 has a pouring mouth 10 and has a flange 12 whereby it is attached to the outside surface of a wall 14 of a plastics-coated paperboard carton.
• the spout 4 is formed externally with screw-threading 16 for co-operating in a conventional manner with internal screw-threading 18 of the cap 6.
• the spout 4 is formed internally with screw- threading 20 for co-operating in a conventional manner with external screw-threading 22 of the piercing device 8 which is in the form of a turnable cutter with knives 24 for cutting through the wall 14 at a zone 26 covered by the fitment 2.
• the cap 6 internally has pushers 28 which cooperate in a conventional manner with dogs (not shown) on the internal surface of the piercing device 8, such that, when the cap 6 is unscrewed, the co-operation between the screw-threading 20 and 22 causes the piercing device 8 to turn about the axis of the fitment 2 while its knives 24 penetrate through the wall 14.
• the wall 14 may be of any desired structure pierceable by the device 8, for example, may, as shown, consist of an outermost, moisture barrier, plastics layer 30 on a paperboard layer 32 itself attached by an adhesive layer 34 to an oxygen barrier, plastics layer 36 covered by an innermost, moisture barrier, plastics layer 38.
• the cap 6 is of relatively transparent plastics material, in particular polypropylene.
• Another possibility is to have the zone to be cut and swung down of a striking colour and/or displaying a special symbol, so that, when the colour or symbol is no longer readily visible, the consumer can conclude that the carton has already been opened.
