6 Claims. 1
This invention relates to molded pulp contain ers adapted to protect fragile articles, particularly eggs, both in the shipping thereof, particularly in standard egg cases, and in the retail packaging of such articles. 7
In the shipping or storage of eggs it has been customary to pack them in crates, each crate holding 30 dozen eggs. The case has a vertical division ,wall and hence has two compartments, each containing 15 dozen eggs, arranged in tiers or layers, 3 dozen in each layer of each compartment. It has heretofore been customary to support each layer by means of a sheet known as an egg fiat, and to separate the 36 eggs in each layer by inter-fitted strips of paper board commercially known as fillers.
With this method of packing, it has been customary for the retailer to unpack the eggs from a crate and re-pack them in retail cartons, each carton customarily holding one dozen eggs. These retail cartons do not have the strength and crushing resistance to withstand normal handling in shipment, and involve an added cost to the retailer.
It is an important object of the present invention to provide a molded pulp carrier or carton for eggs and other-fragile articles, which will be simple in construction, which is adapted as the retail carton itself, and which may be assembled in multiple within the standard crate to hold the usual number of 30 dozen eggs, when eggs are held by the cartons. The carton will give superior protection to the eggs in shipment, and at the same'time will serve as the retail container, so that the retailer is saved the cost of the usual retail container, as well as the labor of re-packing.
The invention will be described with reference to the accompanying drawings, in which:
Figure 1 is a perspective view showing an embodiment of the invention with the left hand cover member raised and folded, ready for final placement, the right hand cover member occupying its normal position, preliminary to the insertion of eggs or other fragile articles;
Figure 2 is a perspective view showing the container closed;
Figure 3 is an enlarged fragmentary view showing one end of the container;
Figure 4 is a vertical section on the line 4-4 of Figure 3; I
Figure 5 is a fragmentary vertical section on the line 5-5 of Figure 4;
Figure 6 is an end elevation of the closed container.
Referring to the drawings, it will be contemplated that the complete structure will be unitary and made of paper pulp in accordance with well known practice. It consists of a body member which is formed, in the present embodiment, with two rows of cups, six in number'as to each longi-' tudinal row, the cups being indicated at 1. Each pair of opposed transversely extending cups is separated by a hollow division wall 2 and the cups of each longitudinally extending row are sepai rated by transverse hollow walls 4.
Extending longitudinally are five posts 5, the
latter rising above the division walls 2 and 4, and
' each post merges into four of said division walls It also will be noted that the body member is provided with an outwardly projected rim comprising two sections, rim section 6 being at a greater height than rim section 1, so that the two rim sections are joined at the ends of the container by a vertical shoulder indicated at 61:.
Preferably formed integrally with the body member are two cover members 8 of identical construction. Each cover member is formed with side wall 83: curved at its ends, and also is formed with a series of frusto-conical members 822x, one for each of the pockets of a row thereof in the body member, the inner wall of each member Bra: being cupped as indicated more particularly in Figure 5 of the drawings. Each cover member is formed with a fold line at 9 so that the lip extension I 0 of each cover member may be folded approximately as shown at the left hand portion of Figure 1.
The wall 8a: of each cover member is joined to the adjacent rim section of the body member through a rim formation of has a fold line at II.
It is preferred that at the base of each cup I, the pulp board be raised to form a cushion member as indicated at la: of Figure 5. It further will be noted that the lip extension IU of each cover member is formed with spaced projections which are adapted to lie between the posts and to rest on the longitudinal division walls 2, the outermost lip extensions bridging the spaces between the outermost posts and the vertical wall 6x of the body member.
The container is well adapted for the packing of eggs or other fragile articles therein by autocessively under a loader, which will drop one dozen eggs or other fragile articles simultaneously into the pockets of the body member. By a succeeding operation the lips ill of the covers will said wall 8a: which be folded upwardly approximately 90 and will be swung inwardly until the areas of the lips l0, between the lipextensions will'enter the slots of I the posts, so" that thecover members will be frictionally held firmly in closed position. Usually a label applied to the closed cover memberswill seal the container, although this is-not essential.
I have shown in dotted'lin'es; Figure. 4,1511%? manner in which the stepped'rim-sections ofthe; body member enable adjacent containers to be so packed in a standard crate thaltrthe latter may hold its customary 30 dozen eggs, notwithstanding the fact that the eggs are packed in individ ual cartons or containers, each holding one dozen eggs, and that thecontainersare-ofsuch. nature; as to protect theeggs toan extentgreater. than the customary; flats and fillers. It. willbe-nseen. by reference to said figure that the high rim 5 of the container'shown' in full lines may lie: over the low rim of an adjacent container, which. is shown in dotted linesat the-left. By dotted lines at E2 in Figure:5 I have shown. an egg: in. position within the closed'container;
It will be understoodrthat various? modifications may be-made intheform andarrangement of the elements illustratedsin the-drawingsiwithout departing from the spiritlof .therinventiom Having thus described.- myinvention, what I claim and desireto secure by Letters Patent; is:as followsz' 1.
