Definitions
- the present invention relates to a sealable metal container.
- the invention provides a means for sealing a metal container which is not made to close tolerances, such as a biscuit tin.
- the end seam between the base and the body of the container; the side seam, where the two ends of the side wall join; and the opening between the lid and the body of the container.
- the end and side seams are made by forming a hook on the edges of the relevant pieces of metal and then folding these hooks together to form a "clinched" seam.
- Such seams are unlikely to be airtight.
- lining compound may be provided inside the seam to form a gasket. Cement or solder may be used to strengthen the side seam and make it airtight.
- the opening in the body for the lid is the normal access point to the container.
- the material used for metal containers, such as biscuit tins, is not normally deformable enough to ensure a mechanical seal by engagement of lid with the body of the tin.
- a number of different methods are already used to seal the opening of these containers.
- a thin membrane of aluminium foil, plastic laminate or impervious film is heat sealed across the opening in the body of the tin or across an insert arranged inside the tin to hold the contents.
- This membrane indicates tamper evidence but has the disadvantage that once the membrane is broken on opening, the lid does not give an effective, continuing, airtight seal and the contents of the tin will gradually start to deteriorate. Even before the film has been torn away from the insert, the product compartment is unlikely to be airtight as the material at the corners of the compartment is often very thin and can leak. Furthermore, some products are adversely affected by the heat sealing process which has to be carried out once the tin has been filled.
- a resilient, pliable gasket may be applied inside the lid so that it sits on top of the body, forming a seal when the lid and the body are closed together.
- a disadvantage of this arrangement is that some form of lid retention is necessary to apply pressure to the lid to maintain the seal, such as screw threads, clips or snap pips.
- this sealing arrangement requires additional processing steps, to insert the gasket into the lid. As the mechanical engagement between the lid and the body of the container is not sufficient to maintain the sealing force, this arrangement may not provide an adequate seal where the tolerances on the body and lid of the tin are relatively loose.
- the simplest method of sealing the lid and the body together consists of externally applying a band of pliable, self-adhesive tape to the tin along the join between the lid and the body.
- this arrangement is unlikely to provide an airtight seal.
- a further disadvantage of this arrangement is that the sealing tape has to be applied under tension. This means that the tin has to be substantially circular or oval, otherwise the tape will sag and an adequate seal will not be obtained.
- US-4,298,134 describes a paint can having a flexible plastic film bag liner.
- the liner is folded back and draped downwardly over the upper outside portion of the can.
- Two downwardly depending concentric rings on the paint can lid provide an liquid-tight seal.
- the aim of the present invention is to provide an airtight metal container having a longer shelf life and which can be resealed by the consumer after initial opening.
- the present invention provides a metal container comprising a body having an opening, a liner arranged within the body and a lid having an end panel and a depending skirt, arranged to engage the body around the opening, in which the liner has an extended portion which passes between the opposed surfaces of the body and the lid, characterised in that the extended portion has a biasing means to bias the liner against the lid to form a seal.
- the container shape can be varied, whilst still retaining an airtight seal between the lid and the body of the container.
- the container may have concave surfaces as part of the side wall, as the seal formed by the liner will accommodate such surfaces. Therefore, contrary to the prior art tins using sealing tape to form a suitable seal, metal containers according to the invention may be made in a wide variety of shapes.
- the liner may be made from a resilient plastics material, for example a soft thermoplastic such as polypropylene or PVC or a suitable laminate.
- the liner may be injection moulded, provided as a thermoform or manufactured using any other suitable techniques.
- the extended portion of the liner is configured so that it is biased against the lid when the lid is placed on the body. Resistance to the deformation of the liner shape provides the necessary sealing force.
- the liner material is preferably sufficiently soft to provide an airtight seal, but stiff enough to provide sufficient resistance to deformation and thereby biasing force.
- the extended portion of the liner may take the form of a folded spring which is normally in an expanded configuration when the body of the container is open but which is compressed when the lid is placed on the body of the container.
- a bead may be provided in the extended portion of the liner which is interposed between the lid and the body. The bead is compressed when the lid is placed on the body, to provide the required sealing force.
- a configuration incorporating a combination of a bead and a folded section may be used.
- the liner according to the invention is provided with an indent which is arranged to co-operate with this curl to prevent the liner being removed from the container with the lid.
- the liner and lid preferably provide a sealed envelope for the product, independent of the body of the container. In this arrangement, there is no need to ensure that the end seam and side seam of the container form a seal as the liner and lid together provide a sealed, airtight compartment for the product. This simplifies the manufacturing process and removes the requirement for expensive cement or lining compound.
- the liner or a portion thereof may be extended below the level of the lid by a sufficient amount that the liner can be pulled upwards to assist in the removal of the lid.
- the lid may be provided with an extended tab or lip under which a consumer can place their fingers to lever the lid off the body of the container.
- a biscuit tin 10 comprises a lid 20, a body 30 and a liner 40, arranged within the body.
- the lid 20 has an end panel 21 and a depending skirt 22 which engages the opening in the body 30.
- the lid 20 may also be provided with an upstanding bead 23 to assist stacking of the biscuit tins.
- the body 30 comprises a side wall 31 and a base panel 32, joined by a clinched seam 33.
- the side wall 31 is provided with a circumferential bead 36 which is located just below the depending skirt 22 of the lid 20.
- the circumferential bead 36 provides rigidity to the body 30 and protects the biscuit tin 10 against impact.
- the bead 36 reduces accidental opening of the lid 20 when subjected to an oblique impact.
- the liner 40 is extended over the curled edge 35 of the opening in the body 30 and is trapped between the depending skirt 22 of the lid 20 and the side wall 31 of the body 30 to provide an airtight seal 45.
- the liner 40 is provided in the form of a folded spring.
- the extended portion of the liner 40 is initially in an expanded configuration 41 when the biscuit tin is open.
- the lid 20 is placed over the opening in the body 30 of the tin, the extended portion of the liner 40 is forced into a compressed configuration 41' by the lid.
- the resilient liner configuration resists moving to the compressed configuration 41', thus biasing the liner 40 against the depending skirt 22 of the lid 20. This biasing force provides the sealing force required to provide an airtight seal 45 around the opening in the tin.
- Figures 5 and 6 show an alternative embodiment of the sealing arrangement, in which the extended portion of the liner 40 has a bead 42.
- the bead 42 is initially in an expanded configuration (as shown in figure 5), before the lid 20 has been placed on the body 30. However, when the lid 20 is placed on the body 30, the depending skirt 22 of the lid 20 compresses the bead 42'. Again, the bead configuration 42, 42' is such that the bead resists this deformation, biasing the liner 40 against the depending skirt 22 of the lid 20 and forming an airtight seal 45.
- the liner 40 may be retained within the lid 20 when the lid is removed from the body 30 of the tin.
- the liner 40 may be provided with an indent 43 which cooperates with the curl 35 around the opening in the body 30.
- the indent 43 in the liner 40 will be arranged on the inside or outside the body 30 of the tin.
- the extended portion of the liner 40 may be extended even further below the curl 25 at the edge of the depending skirt 22 of the lid 20.
- the extended liner tongue 46 may either be provided around the whole periphery of the tin or at one location. In order to remove the lid 20 from the body 30 of the tin, the liner tongue 46 is lifted and thereby prises the lid 20 off the body 30.
- the lower edge of the depending skirt 22 of the lid 20 may be radially extended to provide a lip 26, either locally or around the whole periphery of the lid 20. The consumer can then place their fingers under the lip 26, to apply mechanical advantage to assist lever the lid 20 off the body 30.
