Abstract
Abstract A pack or container for the storage and transportation of fragile articles such as eggs, light bulbs and the like comprises a laminate consisting of a corrugated band or strip and a covering band secured together to give spaced troughs extending transversely of the material, there being spaced, parallel slits in the material extending in the longitudinal direction thereof, the slits extending wholly through the covering band to define separate side-by-side strips thereof and only partially through the corrugated band to define side-by-side strips of such band joined together at the peaks of the corrugations. The junctures form fold lines extending longitudinally of the packing material about which, upon erection of the pack, transversely adjacent regions provide mutually inclined walls defining pockets to receive the articles.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
130 words
A pack for fragile articles, in particular eggs, comprising a plurality of parallel supporting webs extending in the longitudinal direction of the packing material each comprising a corrugated strip (2), the corrugations of the strip having top portions formed with fold lines (32, 33); and a strip-like covering band (3) fixed thereto, which covering band (3) is located on the outside of the pack when in use, said covering band being secured to its corresponding corrugated strip opposite the top portions, thereof the supporting webs (7-11) being connected with one another only on the top portions of the corrugations (5) at the fold lines (32, 33) whereby the supporting webs (7-11) can be placed around the articles (18) to be packed by bending along the said fold lines (32, 33).
Claim 2
Dependent Claim
130 words
A pack for fragile articles, in particular eggs, comprising a plurality of parallel supporting webs extending in the longitudinal direction of the packing material each comprising a corrugated strip (2), the corrugations of the strip having top portions formed with fold lines (32, 33); and a strip-like covering band (3) fixed thereto, which covering band (3) is located on the outside of the pack when in use, said covering band being secured to its corresponding corrugated strip opposite the top portions, thereof the supporting webs (7-11) being connected with one another only on the top portions of the corrugations (5) at the fold lines (32, 33) whereby the supporting webs (7-11) can be placed around the articles (18) to be packed by bending along the said fold lines (32, 33).
Claim 3
Dependent Claim
14 words
A pack according to claim 1, wherein the material of the webs is cardboard.
Claim 4
Dependent Claim
29 words
A pack according to claim 1, wherein five supporting webs (7-11) are provided, the middle web (9) thereof being twice as wide as the two outermost webs (7, 11).
Claim 5
Dependent Claim
19 words
A pack according to claim 1, wherein, when the pack is folded, the covering bands (13) define a rectangle.
Claim 6
Dependent Claim
26 words
A pack according to claim 1, wherein the length (t) of the corrugations determines the pitch distance or spacing of the articles (18) to be packed.
Claim 7
Dependent Claim
54 words
A pack according to claim 5, wherein the length (t) of the corrugations is from two to three times, preferably about two and a half times, the height (h) of the corrugations and wherein the angle (α) enclosed by the inclined faces of the corrugations (19) is between 80° and 110°, preferably about 90°.
Claim 8
Dependent Claim
49 words
A pack according to claim 1, wherein the middle web (9) has a longitudinally extending fold line for forming a double row pack to permit folding the material at the two sides of the said fold line to be in adjacent back-to-back disposition upon erection to form the pack.
Claim 9
Dependent Claim
37 words
A pack according to claim 1, wherein the tops (5) of the corrugations are provided with two lines of weakness (36, 37) arranged parallel to one another and extending transversely to the longitudinal direction of the pack.
Claim 10
Dependent Claim
43 words
A pack according to claim 8, wherein twice the length (s) of the inclined part of the corrugation minus the width (r) of the tops (5) thereof corresponds to the distance (k) between the bending lines (17) at the base of the corrugations.
Claim 11
Dependent Claim
53 words
An erected pack structure, erected from a pack as claimed in claim 1, wherein adjacent webs are disposed at right angles to each other, the end webs (7, 11) abutting each other; and an adhesive cover strip (12) covering both the abutting end webs and securing said end webs in the abutting position.
Claim 12
Dependent Claim
