Definitions

  • This invention is concerned with improvements relating to container closures, particularly for containers used to contain potable liquids such as beer
  • beer is used herein gene ⁇ callv as including mild and bitter beers, stouts, ales, lagers and the like.
  • Difficulty is currently encountered in the provision of container closures for e.g. barrels containing relatively large volumes ot potable liquid (e g in excess of 5 litres) which are tamper-evident - that is, which provide a visual indication ot any attempt to tamper with the contents ot the container prior to opening for use.
  • ot potable liquid e.g in excess of 5 litres
  • a conventional beer barrel comprises a neck having therein a valve means into which a dispenser may be inserted to gain access to the contents ot the barrel. Difficulty is particularly encountered in ensuring that, during transportation from the brewery to the user, no tampering with the contents of the barrel has taken place.
  • a container closure tor a container comprising a body and a neck
  • said closure comprising a) a sleeve member comprising a generallv cylindrical part adapted to be captively retained on the neck of the container, and a plurality ot securing elements lying generally in a plane extending at right angles to the longitudinal axis of the cylindrical part, and extending generallv radially inwardly therefrom; and b) a cover member comprising an end part which is secured or adapted to be secured to the securing elements
  • the securing elements are secured to the cylindrical part ot the sleeve member f ⁇ ably.
  • the sleeve member mav be moulded integrally, the securing elements extending from the cylindrical part bv sprues ot small cross section, whereby the securing elements mav be torn tree of the sleeve part.
  • the cover member or part thereof may be removed from the container with the securing elements to allow access to the neck (e.g. to valve means which may be located in the neck), but preventing the cover member or such part thereof being re-engaged with the sleeve member to re-cover the neck properly.
  • the securing elements are in the torm of tabs, having a relatively extensive flat surface, for securement to the cover member
  • the cover member may be secured to the tabs by adhesive, but is preferably so secured by spot welding, for example by the use of a high treque ⁇ cy machine such as an ultrasonic welding tool.
  • the cover member preferably comprises a cylindrical part and may be so arranged that, on opening thereof, the end part is torn trom the cylindrical part, whereby the two cylindrical parts are retained on the neck of the container, but preferably the cover member as a whole may be lifted trom the container, removing with it the tabs by which the cover member is secured to the sleeve member.
  • the sleeve member is provided with retaining means whereby it may be retained on the neck of a conventional container, such as by the provision of fingers which may releasably be engaged behind the ⁇ m of the neck of the container.
  • the retaining means is capable of engaging containers with necks of at least two different sizes.
  • the sleeve member is provided with means, such as ribs, to centralise it on the neck of the container.
  • the end part of the cover member is in part at least transparent, whereby a label indicating the contents ot the container may be provided.
  • a beer barrel and a tamper-evident closure for the neck thereof having a thickened rim
  • the closure member comprising * a) a sleeve member which mav be fitted around the neck, said sleeve member comprising
  • a generally cylindrical part comprising means to enable the sleeve member to be snap-fitted around the neck in sealing engagement therewith, li) a plurality of fracturable securing tabs extending generally at right angles to the longitudinal axis of the cvlind ⁇ cal part, and b) a cover member comprising a generally cylindrical part which may be located around the cylindrical part of the sleeve member and an end part secured to or which may be secured to the tabs, the construction and arrangement being such that with the closure on the neck, with the end part of the cover member secured to the securing tabs, operative access to the neck is prevented, operative access to the neck being gained by lifting of the cover member or such part thereot away trom the neck of the barrel together with the securing tabs.
  • Figure 1 is a perspective view of the closure, showing a sleeve member and cover member thereof in spaced relationship;
  • Figure 2 is a plan view of the closure
  • Figure 3 is a vertical sectional view showing the closure.
  • Figure 4 is an enlarged view ot part ot the closure showing it in position on the neck of the container;
  • Figure 5 is a perspective view showing a modified torm ot closure
  • Figure 6 is a view of the sleeve member of a modified construction ot the preferred embodiment.
  • FIG. 7 is a sectional view, taken on the line 7 - 7 of Figure o
  • the closure which is the preferred embodiment of the invention comprises a sleeve member ⁇ and a cover member 8
  • the sleeve member 6 comprises a generally cylindrical part 10 having castellated tormations 12 uniformly spaced around the periphery thereof, from each ot which a securing element 14 projects generally radially inwardly, said securing elements 14 extending from the formations 12 by sprues having a small cross sectional area.
  • the elements 14 comprise relatively extensive flat upper surfaces which e generally in a plane extending at right angles to the longitudinal axis of the cylindrical part 10.
  • the cover member 8 also comprises a generallv cylindrical part 16 and an end part 18 closing one end of the part Id, said part 18 being provided with a radially outwardly extending flap or tab 22, which may readily be gripped between the thumb and forefinger, as will be described hereinafter.
  • the sleeve member 10 also comprises, projecting inwardly from the inner wall 11 thereof, with a plurality ot uniformly spaced, upwardly and inwardly inclined resilient fingers 15, affording retaining means of the sleeve member.
  • the closure which is the preferred embodiment of the invention is particularly for use in the closure ot a container, commonly referred to as a "barrel", for containing relatively large volumes (typically in excess of 5 litres) of beer, although it is to be appreciated that the invention may be utilised in the closure of containers used to transport other potable liquids, such as lemonade, cola and the like.
  • containers typically comprise a body, generally indicated at 30 in Figure 4, having a neck 32 which is provided adjacent to an upper end with an enlarged rim 34, the neck having a central opening 36 in which a valve member 38 is located, said valve member being shown only schematically in Figure 4
  • the skirt 10 of the sleeve member is provided with a small outward taper in the downward direction, so that the skirt mav be placed over the neck 32 of the container in sealing engagement with the ⁇ m 34, the tingers 15 being initially compressed as they pass the ⁇ m 34, and adopting their projecting position to prevent the skirt 10 from subsequently being lifted from the container, without destruction thereof.
  • the skirt mav be provided with a plurality ot axial ribs 1 1, shown in Figure 5. to centralise the sleeve member on the neck
  • the skirt 16 of the cover member is similarly provided with a small outward taper in the downward direction, having an internal diameter in relation to the outside diameter of the skirt 10 as to be capable of being loosely interfitted therewith with the end part 18 in contact with the tabs 14 (see Figure 4) In this position, by placing the closure on a suitable die, the cover member 16 may be secured to the sleeve member by spot welding the end part 18 at appropriate positions to the securing tabs 14
  • closure member mav then be titted on to the neck 32 ot the barrel, it being difficult then to remove the closure trom the neck in one piece.
  • the cover member 16 as a whole may be lifted from the barrel, the sprues joining the tabs 14 to the formations 12 fracturing, allowing the tabs to be removed with the closure member 16.
  • the barrel may be used in any conventional manner to dispense the contents thereof.
  • the cover member may be moulded ot transparent plastics material, and overprinted with a label appropriate to the contents ot the container.
  • "windows" 42 are provided, as shown in Figure 5, to enable the integrity of the securement to be confirmed visually
  • additional locating tabs 44 may be provided alongside the securing elements, which seat on the ⁇ m of the neck to prevent the skirt 10 dropping on removal ot the cover, and to provide a register for alignment of the cover and skirt prior to the securement of the cover to the elements 14
  • retaining means comprising f ingers 15a and 15b of different lengths, to enable the cover member to be utilised with containers having necks of slightly different size.
  • the centralising ⁇ os 1 1 a. are effective to centralise the sleeve 8 on the neck of the container particularly when the neck is of the smaller size.
  • a closure tor a container is provided, which is tamper-evident but which may be opened to gain access to the contents of the container relatively easily.
