Enclosures and the tux box

When in the course of an item’s history it becomes clear that the book or artifact could use extra attention, or just another element of design to aid in its care and preservation, we create enclosures. 

Enclosures create a microclimate that provides a darker more consistent environment for works to be stored in. There are many types of enclosures used for many different reasons, ranging from an impermanent simple paper wrap to more long-term solutions such as cloth covered clamshells.   

We use enclosures to provide a range of protection for their contents.

  • A microclimate providing enhanced consistency concerning heat and humidity fluctuations.
  • A barrier against damaging UV rays.
  • Dust and pest control.
  • A strong support for contents.

Because there is so much documentation done on customized high-end enclosures that require greater skill and experience, such as cloth covered clamshells, I will discuss easy to make, low cost enclosures. To be honest, saving time and money is at the forefront of any business.  Enter the elegant tux box.

A tux box serves admirably the need for a cheap, easy first line of defense. We usually create tux boxes using 20-point Bristol board with measurements custom to the book. The tux box provides an adequate barrier against dust and light.  Another virtue of the tux box is that old books that have suffered degradation and have become brittle are provided a more stable structure for storage and handling. It should be mentioned though that because of the nature of the design, temperature, humidity and some dust and light may enter inside the tux box through the exposed corners, possibly allowing these damaging elements inside.

So, let’s make one.  

First make 3 jigs. The jigs will provide a guide to add extra board thicknesses to our book box dimensions to account for overlapping our boards during folding. We use 20-point Bristol board. Our jigs are three thicknesses – 1 thickness, 2 thicknesses and 3 thicknesses. We’ll label them 1,2 and 3.

Let’s also make a handy-dandy information guide that will record all our objects measurements and identifying info on a scrap of bristol board. Record the books thickness (TH), width (W), height (H), call number and title of our book. Use tic marks to record measurements as seen below. This will be useful for quick reference as we create our tux box. 

A paper guide for measuring a tux box, includes height, thickness and width.  Plus name of book and call#

There is a grain direction in Bristol board, (the grain direction is which way the fibers are aligned) for this purpose we will cut 1 length of the Bristol board with the grain running the (H) of our book and 1 length the (W) of our book plus 1 board thickness (W+1BT). 

Use our information guide and jigs to measure, score and fold the horizontal or inner height-based board as follows: (W-1BT), (TH), (W), (TH) then (W-1BT). 

The vertical board, with measurements.

For the outer vertical width-based board we also score and fold starting with an x lightly placed in the corner to identify the outermost flap. With our information guide and jigs and starting from the side with our x we measure, (H), (TH+3BT), (H+1BT), (TH+2BT), (H).  

The horizontal board, with measurements.

Wrap the horizontal piece around the book and then fit it into the vertical part. You can either use double sided tape or PVA to adhere these two together.

Here is the tux box in its open position. Note where the two boards are joined – only the panel where the back cover will sit.

Next, the tricky part. Creating the flap to secure its closed position. Measure, mark and cut the tongue on the outermost flap, let’s use a visual for this part.

Lastly, cut a slot for the tongue to fit into which secures the tux box closed. Close the tux box as if it is finished with tongue out. With a pencil draw a light “v” in the corner where the tab lays closed. Open the tab and place 2 small holes with a Japanese hole punch or an awl. Cut 2 lines connecting the holes forming a slot. Fit tab into the slot to close. Feel free to round the corners of the tab and all flaps using a corner rounder. 

You can also customize tux boxes to accommodate a varity of book sizes. No one wants to add an enclosure to their collection that is the size of a miniature book, it would be so tiny it would get lost. We can adapt the enclosure by adding spacers to bring the overall size of the tux box to at least 5”x7”. 

Here is a link to an adaptation made to a clam shell that could also be used in a tux box as well.

So, the tux box is an easy-peasy solution for an extra layer of strength and protection for its contents. Unlike the Hostess Twinkie, the tux box is not expected to endure the apocalypse. I feel given the cost of materials and time spent to make one, it’s a fine, adaptable addition our enclosure family.
