Abstract
Abstract A container having closure guide members for eggs, fruit or like products, which container is constructed from a sheet of synthetic thermoplastics material and is formed of two parts or portions (9, 10) held together by a flat spine and by two grooves (15) bounding the spine, and having recesses (12) to house the products in at least one of the parts (9, 10) which have mating ledges (22, 22', 22", 22'") and cylindrical spacers (38), the said parts (9,10) being capable of being closed together by means of pressure closure members (16, 17) in such a way that the said mating surfaces are in contact with each other, in which the closure guide members consist of ramps (32, 32', 34, 34', 36, 36') made as a continuation of the grooves (15) on the parts (9, 10) and on the spine (14) and also in which the spacers (19') in the cover (10) are of a height corresponding to the height of said cylindrical spacers (38).

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
155 words
A container having closure guide members for eggs, fruit or like products, which container is constructed from a sheet of synthetic thermoplastics material and is formed of two portions held together by a flat spine and by two grooves binding the spine, and having recesses to house the products in at least one of the portions which have mating ledges and cylindrical spacers, the said portions being capable of being closed together by means of pressure closure members in such a way that the said mating ledges are in contact with each other, in which the closure guide members comprise a ramp made as a continuation of the grooves on the portions and a ramp on the spine, the ramps matingly engaging one another to align the two portions during closure of the container, and also in which additional spacers are provided and are of a height corresponding to the height of said cylindrical spaces.
Claim 2
Dependent Claim
155 words
A container having closure guide members for eggs, fruit or like products, which container is constructed from a sheet of synthetic thermoplastics material and is formed of two portions held together by a flat spine and by two grooves binding the spine, and having recesses to house the products in at least one of the portions which have mating ledges and cylindrical spacers, the said portions being capable of being closed together by means of pressure closure members in such a way that the said mating ledges are in contact with each other, in which the closure guide members comprise a ramp made as a continuation of the grooves on the portions and a ramp on the spine, the ramps matingly engaging one another to align the two portions during closure of the container, and also in which additional spacers are provided and are of a height corresponding to the height of said cylindrical spaces.
Claim 3
Dependent Claim
19 words
A container as claimed in claim 1, in which the ramps end directly at the base of the spine.
Claim 4
Dependent Claim
15 words
A container as claimed in claim 1, in which the ramps consist of inclined planes.
Claim 5
Dependent Claim
14 words
A container as claimed in claim 1, in which the ramps have curved surfaces.
Claim 6
Dependent Claim
26 words
A container as claimed in claim 1, in which the ramps are connected to the base of the spine by ramps at least at their ends.
Claim 7
Dependent Claim
147 words
A container comprising: first and second portions, at least one of the portions having compartments therein for accommodating a product; a spine between the first and second portions; a strip member defining a groove on each side of the spine, each strip member being fixed along one edge thereof to the spine and along the other edge thereof to the first or second portion respectively so that the first and second portions can move relative to each other between a closed and an open position; and closure guide means to facilitate proper alignment of the first and second portions during closure of the container, the guide means comprising a pair of spine ramps on the spine, and a ramp on each of the first and second portions adjacent the strip member which matingly engages one of the pair of spine ramps respectively during closure of the container.
Claim 8
Dependent Claim
147 words
A container comprising: first and second portions, at least one of the portions having compartments therein for accommodating a product; a spine between the first and second portions; a strip member defining a groove on each side of the spine, each strip member being fixed along one edge thereof to the spine and along the other edge thereof to the first or second portion respectively so that the first and second portions can move relative to each other between a closed and an open position; and closure guide means to facilitate proper alignment of the first and second portions during closure of the container, the guide means comprising a pair of spine ramps on the spine, and a ramp on each of the first and second portions adjacent the strip member which matingly engages one of the pair of spine ramps respectively during closure of the container.
Claim 9
Dependent Claim
24 words
A container as claimed in claim 6 further comprising closure means for holding the first and second portions together when in the closed position.
Claim 10
Dependent Claim
53 words
A container as claimed in claim 6 wherein the closure guide means further comprises a projection on one of the portions, the projection having a ramp thereon, and a corresponding recess in the other portion, the recess defining a ramp which matingly engages the ramp on the projection during closure of the container.
Claim 11
Dependent Claim
22 words
A container as claimed in claim 8 wherein the projection and corresponding recess are located on the respective portions adjacent the spine.
Claim 12
Dependent Claim
20 words
