Definitions

  • the present invention relates to a closure that is formed from a polymeric material and is intended for use as a sealing system for a bottle that includes a light weight and relatively non-rigid neck finish .
  • the present invention also relates to an assembly of a closure and a bottle neck, where the bottle neck is made from a light weight and deformable material .
  • the present invention also relates to a bottle that includes the above bottle neck and the above closure applied to the bottle neck .
  • HDPE high density polyethylene
  • an integral handle in HDPE bottles contrasts such bottles with bottles made from the most common alternate material , polyethylene terephthalate (PET) , where integral handles cannot be formed at low manufacturing cost. This effectively confines PET packaging to the less than 2 litre market, where handles are not usually required.
  • PET polyethylene terephthalate
  • a further advantage of the use of HDPE for the manufacture of dairy packaging is an ability to create a very light weight and hence low cost package, in comparison to the quantity of product being packed. This is a highly desirable attribute in the dairy industry, where the core product, white whole milk, is a staple and price driven commodity with little potential for value added manufacture .
  • a consequence of the extreme light weight of dairy packaging is a light weight bottle neck.
  • a typical HDPE blow moulded bottle in the dairy industry has a neck diameter of 38mm for rapid filling, but a wall thickness of less than lmm, commonly less than 0.5mm, and at the extreme less than 0.3mm.
  • a heavy neck on a light weight bottle is not commercially feasible.
  • HDPE bottles are commonly closed with a light weight closure .
  • the seal between the closure and the bottle is not via a screw thread itself, but instead via a "bore seal".
  • a bore seal is a cylindrical skirt (i.e. a ring or a lip) about 2mm long on the inside of a screw closure, which seals against the inside of the top of the screw thread in the neck of the bottle .
  • the light weight closure often also comprises a top panel providing an upper surface and a peripheral skirt comprising inwardly projecting threads designed to engage corresponding outwardly projecting threads on a bottle neck.
  • the threads may be of any suitable design, pitch and depth, including traditional single spiral screw-on, multi-spiral screw-on, or multi- spiral snap-on/screw-off (SOSO) designs.
  • interference fit is used to describe the relationship of diameters. In any given situation, the degree of interference fit is determined by the experience of the designer and by actual practical tests .
  • the light weight closure further comprises a tamper evident means .
  • tamper evident means are in the form of a band which locks onto a corresponding outwardly projecting bead or system on the neck of the bottle, and which is connected by frangible connectors (or bridges) to the lower edge of the peripheral skirt of the closure .
  • frangible connectors or bridges
  • the frangible bridges may be formed directly during closure moulding or be formed in a post moulding slitting operation.
  • a light weight bottle neck typically but not exclusively formed from HDPE, comprises a wall section and a top edge or rim.
  • the light weight bottle neck may further comprise a flange extending inwardly from the rim to increase strength. This flange may be nearly horizontal, but more typically is at an angle increasing in height as the flange progresses in toward the bore to enable trimming.
  • a major consequence of the extremely light weight neck is that it deforms easily and makes a poor contribution to the seal between the neck and its screw top closure.
  • the thread form is too light to allow for force to be vertically applied on the bore seal region.
  • the wall section is too thin to apply significant inwardly acting tensile forces on a bore seal .
  • the neck of the bottle may not be strong enough to resist these outward forces and so moves outwards .
  • the seal is lost and the fluid contained in the bottles starts leaking. This leaking can happen immediately or the neck may creep over time and lead to leaking at a later stage.
  • induction seal foil inserts in closures has been adopted to largely eliminate leakage. This is an effective solution, but not particularly cost effective, with the foil seal adding in excess of 25% to the cost of a closure assembly. Nonetheless, in some markets this has become the default sealing system due to customer demand.
  • a low cost closure, and associated neck design, offering improved sealing performance is a desirable product .
  • the present invention addresses the known inadequacy of sealing in light weight systems by an improved design incorporating additional features at negligible additional cost.
  • the present invention is based on a realisation that the light weight and therefore easily deformable bottle neck construction of the above-described known bottle necks can be utilised advantageously in the design of a closure and a closure and a bottle neck assembly.
  • the present invention addresses the limitation in the seal quality by:
  • the present invention provides a light weight closure and bottle neck assembly.
  • the assembly includes a closure that has a bore seal defined by inner and outer members , such as two concentric skirts .
  • the assembly further includes a bottle neck that includes a flange that is angled inwardly and upwardly at an angle of "theta" to the horizontal, as viewed when the bottle is in an upright position on a horizontal surface.
  • the bottle neck and the closure are formed so that the flange can (a) deflect downwardly in response to an applied top load from the closure as the closure is being applied to the bottle neck and (b) be compressed when the closure is located on the bottle neck and can become wedged with an interference fit in the bore seal .
  • a light weight closure that includes :
  • a second member in the form of an inner concentric skirt depending from the top panel and positioned inwardly of the peripheral skirt and designed to provide a primary bore seal and having an exterior diameter of "Sl";
  • the closure further includes a tamper evident' member .
  • the third member is in the form of an intermediate skirt that extends from the top panel and is concentric with the first and second members and is positioned between the peripheral skirt and the inner skirt to provide contact with an outside of the rim of the bottle neck after the bottle neck engages the primary bore seal and thereby provides the secondary bore seal and resistance to outward flexing of the neck of the bottle, and having an internal diameter of "S2".
  • the third member may be in the form of a pressure block positioned inwardly of the peripheral skirt to provide contact with an outside of the rim of the bottle neck after the bore seal has engaged the bottle neck and thereby provide the secondary seal and resistance to outward flexing of the neck of the bottle.
  • the closure may further include a seal structure on a contact surface of the top panel between the second skirt and the third skirt to provide enhanced top seal .
  • the seal structure may be of any form known in the art.

  • the flange is angled inwardly and upwardly from the top rim at an angle of "theta" to the horizontal .
  • the flange has a width "W" which is greater than a radial gap between the inner skirt and the third member, (such as the intermediate skirt) of the closure , i.e. the difference between diameters E and B .
  • the angle theta is in a range of 3-45° to a horizontal plane, as viewed when the bottle is standing upright on a horizontal surface.
  • angle theta is in the range of 5- 30°.
  • the angle theta is in the range of 5-20°.
  • the bottle neck and the closure are formed, for example as a consequence of the wall thickness and/or the materials selection and/or the construction of the bottle neck and the closure, so that the flange can (a) deflect downwardly in response to an applied top load from the closure as the closure is being applied to the bottle neck and (b) be compressed when the closure is located on the bottle neck and can become wedged with an interference fit in the bore seal, i.e. between the inner skirt and the third member (such as the intermediate skirt) of the closure.

  • a first primary bore seal is formed by contact of an outward surface of the inner skirt of the closure and an inner surface of the bore of the bottle neck, with a contact force being controlled by the difference between diameters B and Sl .
  • a second secondary bore seal is formed by contact between the third member (such as the intermediate skirt) and the outside rim of the bottle neck, with a contact force being controlled by the difference between diameters E and S2.
  • a third tertiary bore seal is formed by contact between an upper surface of the bottle neck, more particularly an upper surface of the inwardly and upwardly angled flange of the bottle neck, and the under surface of the top panel of the closure at final application of the closure on the bottle neck.
  • the inwardly and upwardly angled flange of the bottle neck extends initially at angle theta, typically in the range of 5-45°.
  • the angle decreases as the closure is applied to the bottle neck. This decrease in the angle effectively increases the horizontal component of the width W of the flange, and effectively increases the contact force at both horizontal seal contacts while creating the vertical seal contact.
