This patent application claims priority under 35 U.S.C. § 119 from UK patent application 1811482.7, filed Jul. 12, 2018, and published as GB 2575497 A on Jan. 15, 2020, the entire contents of all of which are incorporated by reference herein.
The present invention relates to improvements in collapsible containers, in particular the present invention relates to improvements in collapsible jugs.
Many collapsible containers have been proposed in the past including those described in US2009183565, US492900, U.S. Pat. Nos. 1,037,068, 1,025,380, and 1,037,985.
The present invention seeks to improve upon the prior art.
According to the present invention there is provided a collapsible jug comprising: an upper member defining an opening and having a spout at a first side of the upper member;
In some embodiments the link is releasably attachable to the lower member by releasable engagement of the link with at least one recess in the lower member.
In some embodiments the second end of the link comprises two flexible prongs that are adapted to engage with:
In some embodiments each flexible prong comprises a projection configured to:
In some embodiments the prongs are pivotable by a user to release the projections from their hooking positions.
In some embodiments when the jug is in its collapsed configuration the upper and lower members are connected together.
In some embodiments when the jug is in its in-use configuration the link is employable by a user as a handle.
Preferably when the jug is in its in-use configuration a space for a user's fingers is defined between the link and the side wall of the jug.
In some embodiments the link comprises a main elongate section and two substantially orthogonal terminal sections.
In order that the present invention may be more fully understood a specific embodiment will now be described by way of example with reference to the accompanying schematic drawings, of which:
Referring to the drawings, container 1, in the form of a jug, comprises an upper member 2, a lower member 3, a handle 4 and a collapsible side wall 5.
Handle 4 is substantially [-shaped, comprising a main elongate section 4a and two substantially orthogonal terminal sections, namely an upper terminal section 4b and a lower terminal section 4c.
Upper terminal section 4b may be considered to comprise the first end of handle 4 and lower terminal section 4c may be considered to comprise the second end of handle 4.
Upper member 2, lower member 3 and handle 4 are all formed of a substantially rigid plastics material whereas side wall 5 is formed of a flexible material so as to allow it to collapse.
Upper member 2 is substantially cylindrical and comprises a substantially circular upper opening 7.
Upper member 2 comprises a spout 6 at a side of upper opening 7 of upper member 2. Pivotally attached to upper member 2 at a point diametrically opposite spout 6 is upper terminal section 4b of handle 4.
Referring to
Each prong 9, 10 comprises is pivotally mounted to lower terminal section 4c of handle 4 such that to one side of the pivot point at the end of handle 4 are located distal portions 9a, 10a of prongs 9, 10, and to the other side of the pivot point are located ribbed proximal portions 9b, 10b.
Adjacent the distal end of each prong 9, 10 is located a respective projection 9c, 10c.
Lower member 3 is substantially disc shaped and comprises at one side a pair of recesses 8a, 8b, which each comprise respective indentations 11a, 11b.
Distal portions of prongs 9a, 10a are configured to be housed within recesses 8a, 8b such that projections 9c, 10c mate with indentations 11a, 11b.
When projections 9c, 10c are mated with indentations 11a, 11b handle 4 as attached to both upper member 2 and lower member 3 such that handle 4 maintains upper member 2 and lower member 3 in a spaced-apart configuration and container 1 is in an ‘in-use’ configuration.
In this configuration a user may fill container 1 with liquid, transport the liquid, and pour the liquid from the container using spout 6.
To detach handle 4 from lower member 3 a user may squeeze proximal portions 9b, 10b of prongs 9, 10 so as to pivot the distal portions 9a, 10a of prongs 9, 10 away from each other and to disengage projections 9c, 10c from indentations 11a, 11b.
Distal portions 9a, 10a of prongs 9, 10 may then be removed from recesses 8a, 8b as handle 4 pivots away from lower member 3.
Once handle 4 is detached from lower member 3 container 1 may be transformed into its collapsed configuration as illustrated in
In order to collapse container 1 a user may twist upper member 2 and lower member 3 relative to each other such that flexible side wall 5 winds up.
Upper member 2 and lower member 3 may then be connected to each other owing to an annular portion 12 of lower member 3 being sized so as to be housed snugly within upper member 2.
In order to releasably secure container 1 in its collapsed configuration a user may then attach lower terminal section 4c of handle 4 to spout 6, as best illustrated in
In this configuration projections 9c, 10c are hooked over the lip of spout 6 such that elongate portion 4a of handle 4 retains lower member 3 between handle 4 and upper member 2.
In this configuration lower member 3 is prevented from disengaging from upper member 2 owing to elongate portion 4a of handle 4.
To detach handle 4 from spout 6 of upper member 2 a user may squeeze proximal portions 9b, 10b of prongs 9, 10 so as to pivot the distal portions 9a, 10a of prongs 9, 10 away from each other and to disengage projections 9c, 10c from the lip of spout 6.
Handle 4 may then pivot away from spout 6 to be reattached to lower member 3 and reinstate container into its ‘in-use’ configuration.
Although in the present embodiment a handle 4 is used to releasably retain container 1 in two different configurations it will be appreciated that a linking member of another type may be employed, said linking member perhaps not usable as a handle when the container is in an ‘in-use’ configuration.
In most embodiments a link is likely to be substantially rigid but in some embodiments a link might be semi-rigid. A link may be formed of one or more pieces.
Many variations are possible without departing from the scope of the present invention as defined in the appended claims.
