15 Claims. (01. 217-35) The invention relates. to a carrier and article nesting arrangement therefor and more esp cially to packing constructions for eggs or other fragile articles.

The primary. object of the invention is the.

provision of a construction of this character, wherein eggs or other fragile articles can be packed so that the same will be suspended in separated relation to each other to avoid possi-' ble contact with each other or with any fixed portion of or within a container or carrier therefor, the suspension being of yielding, adjusting and gripping characteristics as well as assuring the requisite ventilation and light control while 5 the packing is of the staggered principle and in the transportation and handling the liability of breakage or the derangement in the packing is reduced to a minimum, thereby assuring safety both in the transportation. and handling of the packed eggs or articles.

Another object of the invention is the provision of a construction of this character wherein there is employed a novel form of container and a novel form of packing so that eggs or other fragile articles can be packed for transportation thereof in quantities and the'same handled as a unit without breakage, as the eggs or articles are individually supported in suspension and in separated relation to each other and 'in staggered form, with the supports for .the eggs or other articles operative to absorb shocks and jars incident to transportation and handling-and self-adjusting as well as having firm gripping action for. retensioning of the eggs or articles in set condition or nested within the container.

A further object of the invention is the provision of a construction of this character where- V in eggs or other articles can be packed in rows spaced from each other and in superimposed tiers with the rows of each pair staggered with respect to the rows of the next adjacent tiers both above and below and the eggs or articles of the respective rows held nested in suspension through the instrumentality of mats, these being of novel form and of a kind to prevent contamination as the material from which the same are made will be devoid of harmful ingredients and also will eliminate any absorption of moisture highly protective to its contents both in transportation thereof and in the handling of the same and is possessed of strength and durability as well as enabling packed sealing thereof desirable inpreserving the contenw when held. in

storage. I

A still further object of theinvention is the provision of a construction of this character which is comparatively simple in make-up, thoroughly reliable and efficient in its purposes, light of weight yet possessing maximum strength and durability and also inexpensive to manufacture. With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

Referring to the drawings in detail and particularly Figures 1 to 5 inclusive, the container tom l0, ends ll, sides l2 and overlapping extensions I 3, these being integrally formed with'the ends II and are foldable on crease lines I 4 while the ends are foldable on crease lines i5 and likewise the sides I2 being foldable on crease lines It. The sides are integral. with the bottom It and likewise the said ends H are integral with the bottom. In the setting up of the body, the sides l2 are folded on the crease line it to be disposed at right angles to the bottom l and likewise the ends II are foldable on the crease lines l to extend at right angles to the bottom HI while the overlapping extensions I 3 are folded on the crease lines l4 to overli'e the sides l2 exteriorly thereof and these extensions are made secure to the sides through the medium of suitable fasteners I! either of a permanent or detachable character and in the latter nest the said body can be rendered collapsible.

The cover unit. 3 is formed identically to the body unit A and is preferably made from the same material excepting that the overlapping extensions I 8 are of greater extent than the extensions I3 so that with these overlapped sides of this unit B the confronting edges of" such extensions as at l3 meet each otherand are joined in this fashion through the medium of the fasteners 20 which straddle the joints therebetween. The fasteners 20 also join the extensions with the sides 2| of the cover unit 13 and in this fashion the latter is materiallyreinforced at opposlte sides thereof. The cover unit B has its sides and ends of uniform depth to the sides and ends of the body unit A so that the container or.

carrier can be sealed about the free edges of the cover unit to render the same fluid tight. The ends II and 23 respectively of thebody and cover units A and B are provided with matching slots 24 constituting and engaging openings for the easy carrying of the'conta-iner or carrier in the handling thereof during transportation or for placement of the same. These slots 24 can be sealed if found desirableby adhesive tape or otherwise for the sealing of the container or carrier.

- Within the body unit A is a vertical center transverse partition or divider 25, the latter being made from a blank with extensions 26, these being reversely folded on crease lines 21 to each other to confront opposite sides of the body unit Aandalso reversely extending'therein and secured to said sides by the fasteners H or other like fasteners so that in this manner the body, unit will be divided or separated into two like sized chambers or compartments 26 for the pack ing 'of eggs or other fragile-articlestherein in manner presently described.

within the compartments 28 is accomplished by the use of nests C and matsD respectively. The nests 0 each comprises a frame formed of a plurality of spaced crossed partitions or separable strips 2'! and 28 respectively, these being interfltted by slot formation 2i] therein and are suitably interlocked with each other to provide rows of pockets or cells 30, these rows being parallel with respect to each other throughout the extent of the said nest.. At the crossing points of the partitions or strips 2'| and 28 and at the top and bottom edges thereof are provided notch s 3 f r superposed with respect to each other within the v compartments 26 to properly mesh such nests with themats D confined therebetween for the suspension of eggs or other fragile articles within the cells or pockets" 30in these nests in staggered rows with the eggs or other fragile articles of the rows of one tier offset or staggered with relation to the eggs or other fragile articles in the rows of the sub and super tiers in the nestin thereof.

Each mat D is interposed between the nests C when in staggered relation to each other or in other words these mats D are adapted to be disposed above and below each-nest C and these when staggered above each other ,there is located therebetween the said mats D. Each mat comprisesa sheet 33 of flat relatively thin formation, preferably made from pulp board or other suitable material not containing harmful ingredients and preferably of non-absorbing characteristics and this sheet as a part of its construction has stamped or otherwise formed therein, uniformly irregular, or other shaped seats or apertures 34 arranged in rows equi-distanced apart, the seats of one row being staggered with relation to the seats of the next adJacent row and'p'referably these seats each is of circular formation and cut into to provide spaced radially disposed inwardly tapered fingers 35, these converging to the center of said seat 34 but permanently removed therefrom. The fingers 3B in the seats 34 of adjacent alternate rows thereof are reversely distorted or bent so that said fingers will support eggsor'other fragile articles at opposite ends thereof when disposed \within the pockets or cells 30 in the nests C, while the fingers in the seats 34 in one row of one sheet 33 will underlie eggs or other fragile articles when engaged in these seats to support the lowermost ends thereof, while'the fingers in the seats 34 in one row of a sup rposed sheet 33 will overlie or overhang such eggs or articles of this particular row thereof at the upper most ends of such eggs or articles and in this fashion these eggs or articles will be yieldably suspended within the cells or pockets 33 of the nests C. The staggered relation of the seats 34 of alternate rows enables the disposition of registration of the seats ofone -row with the cells or pockets 33 of one'nest C,

ranging of the mats therewith the eggs within the pockets 30 of superposed nests will be held yieldably suspended in the seats 34- by the fingers 35 v and therows of eggs or-other fragile articles so The packing of eggsor other fragile article suspended will be-staggered in one tier relative to those in another underlying or supertier and in this manner the eggs will be prevented from will give added strength and support to the sheet so as to avoid the breaking away of the seat or elongation of the fingers 35 therein.

Adapted to belocated within each compartment 26 of the container or carrier both above and be low the stacked nests C as well as the assembled mats D therewith are cushioning sections 31, these being of a shape corresponding to the compartments 26 to snugly fit therein and to confront the bottom of the body unit A and the top of the cover unit B respectively. Each section 3! is preferably in the form of a paper board having double corrugated filling 38 and a separating layer 39 therebetween, the section being formed with rows of spaced holes 40, these rows bein'g spaced apart in parallel relation to each other and the group of rows of said holes are offset from a pair of the side edges meeting each other of the sections so as to have the holes register with the seats 34 in the mats D next adjacent thereto for appearance of the fingers 35 at said holes 40 in these sections 31, this being clearly illustrated in Figures 9 and 10 of the drawings.

In packing the container or carrier, it will be apparent that the eggs are allowed to rest in the seats 34 of the mats D of those with the fingers 35 concaved while those seats with the fingers convexed overlie the eggs in the respective tiers in the nests C and these fingers take the concave and convex form in conjunction with the natural pliableness of the material of the mat constituting a resting and protecting medium for, each egg, having a natural give to accommodate such egg and a natural firmness to support each egg in place.

The staggered relationship of the eggs confined within the pockets or cells 30 of the nests C and as supported by the'mats D permits of a possible varying air and light control in and about each egg and also allows a fuller and superior display of the egg. Furthermore the eggs in their nesting by the arrangement under the staggered disposition thereof and-the support by the mats D will assure protection to the container A as the same will be held yieldably suspended in the respective nests C without liability'of contact with each other or with the wallsof the pockets or cells 30 of the nests or the walls of the container or carrier and thus safety is assured in transportation, handling and storage.

The disposition and associated relationship of the nests C, mats D and sections 31 with the eggs confined within the cellsor pockets 30 in said nests C and the stacked condition thereof within the compartments 26 in the body unit A of the carrier or container is clearly illustrated in Figures 9 and 10 of the drawings.

- Located removed from each marginal edge of the mat D and parallel therewith for a major extent thereof is an imprint constituting a corrugation 4| to effect a reinforcing rib, thus giving added strength and support to the said mat as will be obvious.
