Originally known by its inventor’s name(Hough Land). this style is more generally known today as the 1-2-3 closure. Usually paired with a top tuck closure, the 1-2-3 is almost always employed as a bottom closure, and is assembled and sealed manually. This closure sytle may be applied in a shallow-depth, tube-style counter display carton, as well as in the proportion shown here, Also known as 1-2-3 bottoms for their simple and easy method of construction, snap lock bottoms are the ultimate in quick convenience. This type of bottom not only allows your cartons to be shipped folded to save space and money, but also can be assembled quickly to save time. Because snap lock bottom folding cartons can be shipped flat, which can be fit into one shipment, reducing shipping costs. Plus, these cartons can be easily stored, allowing you to use the ones you need and keep the rest out of the way. When you need them, snap lock bottoms assemble”in a snap”, so you can spend your time on the profitable sides of your business rather than wasting time assembling boxes, below picture shows an example of the application of end-locked folding carton, and illustrates the structure of end-locked folding carton.
The four flaps that form the bottom panel are die cut. To set up, the user folds the lagest bottom panel first, then the two end panels. When the remaining bottom panel is folded and pressure is applied near the center, the flap “snaps” into the slot created by the other panels. The style is convenient for small-volume shippers who do not have automatic set-up equipment. Because the bottom is not fully sealed, it may not be suitable for heavy products or concentrated loads. This style can be provided in “tuck-top” top flaps. RSC style or other configurations.
