outer end panels

23, 23 along the second fold line 26, and each of the pair of outer end panel flaps34 is set off from the second top panel 33 along a second piar of

cut lines

35, 35.

The container of FIGURES 2 through 5 of the drawings is erected from the container blank 11 by folding both

inner end panels

21, 21 and the side panels 18 i and 20 normal to the bottom panel 12 along the respective A'central divider 37 includes a substantially rectangi ular central portion 38 and a pair of identical oppositely

directedattaching strips

40, 40. The central divider or partition 37 is preferably constructed from corrugated paperboard or similar paperstock material and is secured to the

side panels

18 and 20 by a plurality of staples 41,

identical to the staples 36. The central divider or partition 37 divides the corrugated container 10 into two i identical compartments 42, each of which is designed to i hold approximately 15 dozens of egg cases.

After the corrugated container 10 is filled, the outer

end panel flaps

34, 34 are each folded along a second fold line 26. The first top panel 31 is folded along the third fold line 32 and the second top panel 33 is folded along the second fold line 26 to the position illustrated in FIGURE 4 of the drawings. The

top panels

31 and 33 are then secured in a conventional manner, for example, by a piece'of pressure-sensitive tape, and the corrugated container 10 is ready for shipment.

To aid in collapsing the corrugated container 10 from the position shown in FIGURE 3 to the collapsed posiit tion of FIGURE 2, the container blank 11 of FIGURE 1 is provided with a pair of identical weakening lines 43 forming extensions of the fold line 17. These weakening lines 43 may, for. example,;be in the form ;of fold lines. An identical weakening line 44 is also formed in each of the outer end panels 23 normal to the weakening line 43 in the inner end panels 21,121. The relationship I of the inner end panels 21, and the outer end panels 23 cause the

weakening lines

43 and 44 to overlap one another when the corrugated container 10 is erected to the position shown in FIGURE 3. The overlappingbf the

weakening lines

43 and 44 allow the

abutting end panels

21 and 23 to readily fold inwardly toward each other as shown in FIGURE 2.

A substantially rectangular, identical inner end panel 57 is joined to the rectangular :bottom panel 48 along each of the first pair of

fold lines

50, 50. Each of the inner end panels 57, includes an elongated access opening or hand gripping opening 58 which extend substantially parallel to the first pair of

fold lines

50,50.

A substantiallyrectangular outer end panel 60 and a substantially rectangular, narrow securing or reinforc- The central divider or partitionv ing -strip 61 are secured to the substantially rectangular side panel 56 along an associated one of a third pair of

fold lines

62, 62. The third pair of

fold lines

62, 62 form extensions of the first pair of

fold lines

50, 50. The substantially rectangular outer end panel 60 is provided with an elongated access opening or hand gripping opening 63 which is positioned substantially normal to the elongated access opening 58 of the adjacent inner end panel 57.

A substantially rectangular outer end panel 64 and a substantially rectangular, narrow, securing or reinforcing strip 65 are each secured to the first side panel 55 along an associated one of a fourth pair of

fold lines

66, 66. An elongated access opening or hand gripping opening 67 is formed in the outer end panel 64 and extends in a direction substantially normal to the elongated access opening 58 in the adjacent inner end panel 57.

The

outer end panels

60 and 64 and the securing

strip

61 and 65 are engaged in a cater-corner relationship with respect to the bottom panel 48, This cater-corner relationship of the

outer end panels

60 and 64, and the securing

strip

61 and 65 serve to reinforce opposed corner seams of the corrugated container 46 of FIGURE 7 in a manner which will be described more fully hereafter.

A substantially rectangular first top panel 68 is secured to the first side panel 55 along a first tfiold line 70. The first top panel 68 is set oil from an outer end panel flap 71 of the outer end panel 64 by a out line 72. The outer end panel flap 71 is joined to the outer end panel 64 along a fold line 73. v

A second substantially rectangular top panel 74 is joined to thesecond side panel 56 along a fold line 75. The second top'panel 74 is set off from an outer end panel flap 76 of the outer end panel 60 by a outline 77. The outer end panel flap 76 is joined to the outer end panel 60 along a fold line 78.

The corrugated container 46 of FIGURE 7 of the drawings is erected from the container blank 47 by folding the

inner end panels

57, 57, the first side panel 55 and the second side panel 56 substantially normally to the bottom panel 48. The outer end panel 60 is then folded along the adjacent fold line 62 into overlapping contact with the securing strip 65 which is folded along the adjacent fold line 66, as is clearly shown in FIGURE 7 of the drawings. The outer end panel 64 and the securing strip 61 are folded in a manner substantially identical to the folding of the outer end panel 60 and the securing strip 65. The securing strip 65 is thus sandwiched between the outer end panel 60 and an adjacent sandwiched between the outer end panel 64 and an adjacent inner end panel 57. A plurality of staples (not shown) such as the staples 36, secure the securing strips 61 and 65 to the respective

outer endpanels

64 and 60 and alsoto the

inner end panels

57, 57. The securing strips 61 and 65 thus form reinforced seams at opposite corners of the corrugated container-s 46.

The corrugated container 46 of FIGURE 7 can be collapsed in a manner identical to that heretofore discussed in connection with the corrugated container of FIGURES 2 through 5 of the drawings. To facilitate this collapsing, the corrugated container 46 and the blank 47 thereof are provided with a pair of identical weakening lines 80, similarto the weakening lines 43 of the container blank 11, forming extensions of the fold line 54. An identical weakening line 81 is also provided in each of the

outer end panels

60 and 64 normal to the weakening lines 80 in adjacent ones of the

inner end panels

57, 57. The relationship of the

inner end panels

57, 57 the outer end. panel 60 and the outer end panel 64 cause the weakening lines 80 and 81 to overlap one another when the corrugated container 46 is erected to the position shown in FIGURE 7, just as the weakening

lines

43 and 44 of the corrugated container 10 of FIGURE 2 overlap.

A central divider 83 (see FIGURE 7), identical to the central divider or partition 37, is secured to the

side panels

55 and 56 in a manner heretofore mentioned in the description of the corrugated container 10. The central divider or partition 83 is also provided with a weakening line (not shown) similar to the weakening line 45 of the central divider 37. 7

Another corrugated container constructed in accordance with this invention is illustrated in FIGURES 9 and 10 of the drawings and is generally designated by the reference numeral 85. The corrugated container 85 is erected from a corrugated paperboard container blank 86 of FIGURE 8.

The corrugated container blank 86 of FIGURE 8 includes a substantially rectangular bottom panel 87 set off by a first pair of fo'ld lines 88 and a second pair of fold lines 90, 90. A pair of

angular fold lines

91, 91 converge away from each of the first pair of spaced

parallel fold lines

88, 88 and define therewith a pair substantially identical

triangular areas

92, 92. A fold line 93 extends between 'the pair of

angular fold lines

91, 91 substantially midway between the second pair of fold lines 90, and substantially normal to the first pair of

fold lines

88, 88.

A first substantially rectangular side panel 94 is joined to the substantially rectangular bottom panel 87 along one of the second pair of fold lines 90, 90. A second substantially rectangular side panel 95 is similarly joined to the substantially rectangular bottom panel 87 along another of the second pair of fold lines 90, 9,0.

A substantially rectangular, identical, inner end panel 96 is joined to the rectangular bottom panel 87 along each of the first pair of

fold lines

88, 88. 'Each of the inner end panels 96 includes an elongated access opening or hand gripping opening 97 which extends substantially parallel to the first pair of

fold lines

88, 88. I

An identical, substantially rectangular outer end panel 98 is secured to the second side panel 95 along each one of a third pair of

fold lines

100, 100. Each of the outer end panels 98, is adjacent an associated one of the inner end panels 96 and separated therefrom by an identical out line 101, 101. An elongated access opening or hand gripping opening 102 is formed in each of the

outer end panels

98, 98, and each of the elongated access openings hcs substantially normal to each of the

elongated access openings

97, 97 of the

inner end panels

96, 96.

An identical, elongated, substantially rectangular narrow securing or reinforcing strip 103 is secured to the first substantially rectangular side panel 94 along each one of a fourth pair of

fold lines

104, 104. The securing or reinforcing

strips

103, 103 cooperate with the

inner end panels

96, 96 and the

outer end panels

98, 98 in a manner which will be more fully described hereafter.

A first substantially rectangular top panel 105 is joined to the first side panel 94 along a fold line 106. A similar substantially rectangular second top panel 107 is joined to the second side panel 95 along a fold line 108.

A pair of identical, substantially rectangular outer end panel flaps 110, 110 are each joined to an associated one of the

outer end panels

98, 98 along the fold line 108. Each of the pair of outer end panel flaps 110, 110 is set off from the substantially rectangular second top panel 107 by a pair of identical cutlines 111, 111.

The corrugated container 85 of FIGURES 9 and 10 of the drawings is erected from the container blank 86 by first folding both

inner end panels

96, 96, and the

side panels

94 and 95 normal to the bottom panel 87 along the respective pairs of fold lines 88, and 90. The securing or reinforcing strips 103 are folded along the fold lines 104 into overlapping contact with each of the

inner end panels

96, 96 as is best illustrated in FIGURE 10 of the drawings. The

outer end panels

98, 98 are then folded along the

fold lines

100, 100 into overlying engagement with the securing strips 103. A plurality of staples 112 secure the

panels

96, 93 and the reinforcing strips 103 together 7 in a manner clearly illustrated in FIGURE 10 of the drawings.

A central divideror partition 113, identical to the

central dividers

37 and 83, is secured between the

side panels

94 and 95 by a plurality of staples 114. The central divider or partition 113 divides the corrugated container 85 into two identical compartments 115, each of which is substantially identical to the compartments 42 of the corrugated container 10.

The corrugated container 85 is collapsible, and to facilitate this collapsing, the corrugated container 85 and the blank '86 thereof is provided with a pair of identical weakening lines 116 forming extensions of the .fold line 93 in the bottom panel 87. These weakening lines 116 are identical to the weakening lines 43 and 80, and take the form of fold lines or partial lines of severance. An identical weakening line 117 is also formed in each of the

outer end panels

98, 98 normal to the weakening lines 116, extending into each of the

inner end panels

96, 96. The relationship of the inner end panels 96 and the outer end panels 98 again cause the weakening lines 116 and 117 to overlap one another when the corrugated container 85 is erected to the position shown in FIGURES 9 and l of the drawings. The overlapping of the weakening lines 116, and 117 operate in a manner identical to that heretofore discussed in the consideration of the corrugated container 10, and a further description is deemed unnecessary for a complete understanding of this invention. Similarly, the central divider 113 is also provided with a weakening line 118 which is identical to the weakening line 45 of the central divider 37 and functions in a manner described thereto.
