Some (non-intersecting) “twin packs”
In our previous post we showed you a hypothetical structure for a pair of intersecting milk cartons.
Today we bring you a similar (albeit non-intersecting) idea: “twin pack milk cartons.”
Culled from American grocery store ads, I found these images in newspapers published between 1952 and 1976. I’ve also seen some more recent examples. (This “unitary” twin pack on Polypack’s website, for example.)
Some dairies sold quart size milk cartons paired together in “half gallon twin packs.” Mostly what you find, however, are half gallon size cartons paired together as “gallon twin packs.”
Benefits of “Twin Pack Cartons”
When first introduced, a dairy would often advertise the benefits of the new packaging. For example:
- Saves Money
- Easier to Carry
- Keeps Milk Fresher
Twin Packs & Contents Declaration
Labeling these cartons posed some communication problems for their designers. Since the twin packs are separable, each carton must show its correct individual volume. But, the dairy would also want to highlight the twin pack’s combined total volume.
Sometimes they solved this by printing the total volume in words (“HALF GALLON” or “ONE GALLON”) spanning across both cartons. Other times the cartons are just the same as the ones sold individually, and it’s only the handle that shows the total combined volume.
Regulations & Prohibited Twin Packs
As popular as these were with consumers, they were surprisingly controversial in Pennsylvania.
From the articles I’ve skimmed, I gather that, in the early 1960s, Country Belle Cooperative Farmers tried to introduce the twin pack (already in use in many other states) to Pennsylvania.
The State Milk Commission opposed the new packaging. There were hearings. And decisions. And appeals, etc. Meanwhile, consumers appeared to be fully in favor of the new twin pack. Read-all-about-it, after the fold…
