Abstract
Abstract In a method of making boxes with flap tops or push-on lids from flat carton blanks, two opposed side flaps of the lid blank are provided with adhesive, the base blank is pushed below the lid blank at a spacing at least equal to the height of the side flaps, two corresponding side flaps of the base blank are folded up at right-angles, the said two side flaps of the lid blank are folded down onto the upstanding side flaps of the base blank and adhered thereto, two further opposed side flaps of the base blank are bent upwardly, two corresponding further side flaps of the lid blank are provided with adhesive and folded down onto and adhered to the said further side flaps of the base blank, the interconnected completed base and lid of the box have a paper covering adhered over them, and an incision is made for severing at least three of the side flaps of the lid.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
200 words
A method of making boxes from carton blanks, of the type having either flap tops or push-on lids and which after being formed and covered with paper are incised along edges of the box lid opening, comprising the steps of: adding a substantially quick-settling adhesive to and margins of opposed side flaps of a lid carton blank; positioning a base carton blank in aligned registered disposition beneath the lid carton blank and spaced therefrom a predetermined distance corresponding to the width of the finished box; erecting to a substantially vertical positon side flaps of the base carton blank underlying the lid side flaps carrying adhesive; folding the lid side flaps carrying adhesive to and into pressed engagement with the vertical base side flaps; erecting to a substantially vertical position the remaining side flaps of the base carton blank; adding said adhesive to end margins of the remaining side flaps of the lid carton blank; folding the remaining lid side flaps to and into pressed engagement with the remaining vertical base side flaps, thereby forming a closed box; applying a paper covering to the closed box; and incizing and severing the outer side flaps of the box lid at predetermined locations.
Claim 2
Independent Claim
200 words
A method of making boxes from carton blanks, of the type having either flap tops or push-on lids and which after being formed and covered with paper are incised along edges of the box lid opening, comprising the steps of: adding a substantially quick-settling adhesive to and margins of opposed side flaps of a lid carton blank; positioning a base carton blank in aligned registered disposition beneath the lid carton blank and spaced therefrom a predetermined distance corresponding to the width of the finished box; erecting to a substantially vertical positon side flaps of the base carton blank underlying the lid side flaps carrying adhesive; folding the lid side flaps carrying adhesive to and into pressed engagement with the vertical base side flaps; erecting to a substantially vertical position the remaining side flaps of the base carton blank; adding said adhesive to end margins of the remaining side flaps of the lid carton blank; folding the remaining lid side flaps to and into pressed engagement with the remaining vertical base side flaps, thereby forming a closed box; applying a paper covering to the closed box; and incizing and severing the outer side flaps of the box lid at predetermined locations.
Claim 3
Dependent Claim
18 words
The method of claim 1, wherein said incizing is performed prior to the application of the paper covering.
Claim 4
Dependent Claim
17 words
The method of claim 2, wherein said incizing forms a plurality of incisions interrupted by web portions.
Claim 5
Dependent Claim
18 words
The method of claim 1, including the further step of prescoring the lid side flaps to be incised.
Claim 6
Dependent Claim
300 words
Apparatus for forming boxes having either flap tops or push-on lids from lid and base carton blanks, comprising, in combination: A first pair of substantially parallel guide rails with planar tops and having outer edges thereof spaced apart a distance corresponding to an interior dimension of a box to be formed, a second pair of guide rails extending substantially parallel with respect to the first pair of guide rails and spaced from one another a distance corresponding to the height of side flaps of a lid of a box to be formed, a conveyor which extends through the first pair of guide rails, spaced means on said conveyor for carrying box lid blanks thereon, means disposed between each pair of the respective guide rails for applying adhesive to portions of box lid side flaps, a box base blank guide, means disposed under the first pair of guide rails for inserting base blanks on to said box base guide in a direction traversed by the spaced carrying means, means downstream of said inserting means provided with run-up faces for folding side flaps of a box base blank onto vertical outer sides of the first pair of guide rails, means downstream of said folding means and provided with run-up faces for folding glued side flaps of a box lid onto upstanding side flaps of the box basem means for pressing the folded side flaps of the lid and base onto one another, means for turning through substantially 90° in the conveying direction the lid and base box portions, and means downstream of the turning means for erecting side flaps of the box base blank and for gluing portions of the box lid side flaps and further for pressing the glued box lid side flaps against the side flaps of the box base.

Dependent Claim
300 words
Apparatus for forming boxes having either flap tops or push-on lids from lid and base carton blanks, comprising, in combination: A first pair of substantially parallel guide rails with planar tops and having outer edges thereof spaced apart a distance corresponding to an interior dimension of a box to be formed, a second pair of guide rails extending substantially parallel with respect to the first pair of guide rails and spaced from one another a distance corresponding to the height of side flaps of a lid of a box to be formed, a conveyor which extends through the first pair of guide rails, spaced means on said conveyor for carrying box lid blanks thereon, means disposed between each pair of the respective guide rails for applying adhesive to portions of box lid side flaps, a box base blank guide, means disposed under the first pair of guide rails for inserting base blanks on to said box base guide in a direction traversed by the spaced carrying means, means downstream of said inserting means provided with run-up faces for folding side flaps of a box base blank onto vertical outer sides of the first pair of guide rails, means downstream of said folding means and provided with run-up faces for folding glued side flaps of a box lid onto upstanding side flaps of the box basem means for pressing the folded side flaps of the lid and base onto one another, means for turning through substantially 90° in the conveying direction the lid and base box portions, and means downstream of the turning means for erecting side flaps of the box base blank and for gluing portions of the box lid side flaps and further for pressing the glued box lid side flaps against the side flaps of the box base.
Claim 8
Dependent Claim
45 words
Apparatus according to claim 5, further comprising a magazine for holding box lid blanks at a location upstream of said first pair of guide rails, said magazine having a lower slot through which box lid blanks are pushed onto said first pair of guide rails.
Claim 9
Dependent Claim
16 words
Apparatus according to claim 6, further comprising feed rollers disposed between said magazine and said conveyor.
Claim 10
Dependent Claim
17 words
