Definitions

  • the present disclosure relates to containers, more particularly, but not exclusively, to 'squeeze-open' containers.
  • a known squeeze-open container is described in W095/23743.
  • the container is discshaped and takes the form of a base, which defines a chamber for product, and a lid intended to be releasably attached to the base, in order to define a closure for the chamber. Releasable attachment is achieved via a snap-fit engagement between the lid and the base, which also serves to enable easy detachment of the lid from the base, upon squeezing of the lid.
  • An object of the present disclosure is to provide improvements or alternatives to the containers described and illustrated in W095/23743. Aspects of the present disclosure are set forth in the accompanying independent claims. Optional features of embodiments are set out in the dependent claims.
  • a container comprising a body and a lid.
  • the body defines a chamber having an open mouth with a central axis and the lid is intended to cover said open mouth.
  • the body and lid are configured to cooperate with one another to provide snap-fitting engagement therebetween, in order to releasably attach the lid to the body.
  • the body has an external face, and the lid includes an internal face intended to overlap at least a portion of said external face of the body when the lid is releasably attached thereto.
  • the body and lid are of plastics construction.
  • the lid is configured for sealing engagement with the body.
  • the open mouth of the chamber has an upper lip.
  • the lid may include an annular and resilient tongue, which defines a cantilever.
  • the tongue may be configured so that an underside of said cantilever is in biased sealing contact with said lip when the lid is releasably attached to the body.
  • the tongue extends from an internal surface of the lid.
  • the tongue is configured for continuous sealing contact with the lid.
  • the tongue extends in a direction orthogonal to the central axis.
  • the lid may comprise a cover wherein the cover extends across the mouth of the body, when the lid is releasably attached to the body.
  • the lid may comprise a
  • the internal face forming part of the side wall, such that the side wall overlaps at least a portion of the external face of the body when the lid is attached to the body.
  • the tongue extends radially inwardly from the side wall of the lid.
  • the tongue extends in a direction away from the cover of the lid, for example, at an acute angle to the cover of the lid.
  • An acute angle may also or alternatively be formed between the side wall of the lid and the tongue.
  • the tongue is configured to extend in a direction away from the cover of the lid such that an angle of between 20 and 70° is formed between the tongue and the cover of the lid, for example, between, 30 and 60°, for example, between 40 and 50° from the cover.

Once the tamper evident strip 120 has been removed from the container 10, the lid 14 may be removed from the body 12 in the manner previously described (see Figures 81 and 82). Any suitable tamper evident solution can alternatively be used.
  • the lid 14 of embodiments described herein may be coupled to the body 12 by a hinge.
  • the container comprises such a hinged lid.
  • the embodiment shown in Figures 83 to 87 comprises a body 12 that defines a chamber having a larger volume than the lid 14.
  • the body 12 comprises a neck 110 coupled to the main body portion 112 by a shoulder 114.
  • the neck 110 has a smaller diameter than the region of the main body portion 112 immediately below the shoulder 114.
  • the neck has a smaller diameter than the rest of the body 12.
  • the lid 14 is configured to overlap the neck when the lid 14 is releasably attached to the body 12, as previously described in relation to Figures 78 to 82.
  • the side wall 14a of the lid 14 comprises a region of relatively long length and a region of relatively short length.
  • the region of relatively long length defines a tab 100 extending from the cover 14b of the lid substantially parallel to the side wall 12a of the body 12 when the lid is releasably attached to the body.
  • the region of relatively short length defines a reduced side wall portion 108 extending from the cover 14b of the lid substantially parallel to the side wall 12a of the body 12 when the lid is releasably attached to the body.
  • a void 102 is defined in the side wall 14a of the lid 14 by the tab 100 and the reduced side wall portion 108, as can be seen clearly in Figure 85.
  • the concave surface of the shoulder 114 engages the tab 100 of the lid 14, for example the lower edge of the skirt 26 of the side wall defining the tab 100, and forces the lid 14 away from the body 12 as the tab 100 is pressed towards the central axis, i.e. towards the neck 110 of the body 12.
  • the shoulder 114 of the body 12 is shaped to complement the shape of the lower edge 26 of the lid 14.
  • the shoulder 114 is shaped to complement the shape defined by the tab 100 and void 102 of the lid 14.
  • the position of the shoulder 114 relative to the mouth of the neck 110 varies such that the distance between the shoulder 114 and the mouth of the neck 110 is smallest in the region corresponding to the void 102 of the lid and largest in the region corresponding to the tab 100 of the lid.
  • variation of the shoulder in this way defines a single recess 106, shaped such that, when the lid 14 is releasably attached to the body 12, the tab 100 occupies the region defined by the recess 106, and a single projection 104 shaped such that, when the lid 14 is releasably attached to the body 12, the projection 104 occupies the space defined by the void 102.
  • a hinge component 130 extends from the projection 104 of the body 12 to couple the lid 14 to the body 12.
  • the hinge component 130 is provided in the centre of the projection 106, i.e. equidistant from either side of the tab 100.
  • the outer face of the tab 100 defines a pair of depressions 116, for example positioned diametrically opposite each other, indicating an optimal position for the side wall 14a to be pressed towards the neck 110 in order to release the lid from the container.
  • this depression 116 may be provided in the region of the side wall 14a between 5 and 20mm from the crest of the ridge 46 of the second formation 24, between the second formation and an edge of the lid distal the cover, e.g. the lower edge 26 of the lid, for example, between 8 and 16mm.
  • the depressions 116 are positioned equidistant from the hinge 130.
  • the hinge 130 is provided equidistant from the pair of depressions 116. By locating the depressions 116 in this position relative to the hinge 130, the lid 14 is pressed towards the neck 1 10 of the body 12 at an optimal location to facilitate effective release of the lid 14 from the body 12.
  • the hinge component 130 is a live hinge.
  • any other suitable hinge mechanism may be used, for example a hinge component comprising a hinge pin, a hinge component formed separately from the lid and/or body, a hinge comprising a plurality of hinge mechanisms, or any other suitable hinge as will be understood by those skilled in the art.
  • a bore seal 54 is provided extending from the internal cover surface 32 of the lid and arranged to sealingly engage an internal surface of the open mouth of the neck when the lid is releasably attached to the body.
  • the bore seal 54 is similar to that previously described in relation to Figures 17 to 20. It will be appreciated that any other sealing means described herein may alternatively or additionally be employed, or optionally no sealing means need be provided.
  • the tab 100 is pressed towards the neck of the body 12, preferably in the region of the depressions 116, in order to flex the side wall 14a of the lid and thereby disengage the second formation 24 from snap- fitting engagement with the first formation 22.
  • the lid 14 pivots about the hinge 130 to an open position. In this way, the lid and body remain coupled together while the container is open.
  • An advantage of this is that the container may be held in only one hand, leaving the other hand free to access the contents of the container.
  • Figures 88 to 93 comprises a container of the kind illustrated in Figures 83 to 87 adapted to include a tamper evident feature in the form of a strip 132.
  • the lid is provided with an additional void 102 in the tab 100, opposite the hinge 130, e.g. between the two depressions 116 previously described. Consequently the lid 14 comprises a pair of voids 102 positioned diametrically opposite each other and a pair of tabs 100 positioned diametrically opposite each other, wherein the hinge element 130 is provided adjacent one void 102, and the tamper evident strip 132 is configured to occupy the other.
  • the strip 132 When in place on the container 12, i.e. when the lid 14 is snap-fittingly attached to the body, the strip 132 is configured to occupy the region of the recess 106 defined by the body in between the region occupied by the pair of tabs 100. In other words, the tamper evident strip 132 is arranged to occupy the additional void 102 provided opposite the hinge 130. Accordingly, when the tamper strip 132 is in place, a uniform and aesthetically pleasing appearance is provided, as shown in Figure 88.
  • the neck 110 of the body is provided with a projection 134 extending
  • the strip 132 is provided with a complementary projection 136 arranged to engage the projection 134 of the neck 110 (i.e. to engage the side of the projection 134 away from the lid).
  • the projection 136 of the strip 132 engages the projection 134 of the neck 110 and the strip 132, e.g. an edge of the strip, is fused to the lid 14 at a plurality of points along the edge of the strip 132.
  • the tamper evident strip 132 also comprises a pull tab 138 extending from the strip 132. To remove the tamper evident strip 132, the pull-tab 138 is pulled away from the container 10, thereby breaking the plurality of joins between the lid 14 and the strip 132 (see Figure 89). Once the tamper evident strip 132 has been removed, the lid 14 may be released from the body 12 in the manner previously described.
  • the features of the shaped lid and/or body side wall, hinge and/or tamper evident features may be applied to any of the embodiments described herein.
  • the embodiments described herein refer to the side wall 14a of the lid 14 being arranged to extend from a cover 14b of the lid 14, it will be appreciated that the cover 14b need not be provided such that it is substantially perpendicular to the side wall 14a.
  • the cover 14b is not limited to being substantially planar.
  • the cover 14b and side wall 14a may comprise a curved outer profile, for example, such that they form a continuous curved outer surface.
  • the cover and/or side wall may comprise a substantially hemispherical outer profile.
  • sealing mechanisms described in relation to the exemplary embodiments shown in Figures 1 to 56 are applicable to containers having a body comprising a ramp and groove formation, like those described in relation to the exemplary embodiments shown in Figures 57 to 93. That is, those in which the lower end of the lid is intended to cooperate with part of a groove or ramp surface on the body for a 'squeeze and release' operation.
  • the sealing arrangement and features in relation to the covering described in relation to the exemplary embodiments shown in Figures 57 to 72 are applicable to the containers described in relation to the exemplary embodiments shown in Figures 1 to 56 and 73 to 93.
  • FIG. 1 to 72 show a container wherein the volume of the lid is substantially the same as the volume of the body. However, the body may be of a different volume, e.g. see the exemplary embodiments described in relation to Figures 73 to 93.
  • the body may define a chamber of significantly greater volume than the lid, such as in excess of two times the volume of the lid.
  • the body is of bottle-type construction, defining a chamber having an internal capacity of 200-300 millilitres.
  • the body may be of generally uniform diameter.
  • the body may define a neck having a diameter significantly smaller than the diameter of the rest of the body, and further wherein lid is configured to overlap a portion of the neck, once releasably attached to the body.
  • the body will define a shoulder immediately below the neck. The lower end of the lid may be spaced from or configured to nest with the shoulder on the body, once the lid has been releasably attached to the body.
