The smart Trick of red brand canners hbr case solution That Nobody is Discussing

  The array of references utilized to assistance the conclusions and estimates uncovered below - such as the outlined relationship ranges - are famous.  Additional information and facts and estimates are according to the empirical observations from the author around fifty many years of encounter; a simple fact usually although not often observed.

Each individual from the pictured bottles has a comparatively brief description and clarification which includes an believed day or date vary for that sort bottle and hyperlinks to other look at pics in the bottle.  Further inbound links to photographs of comparable bottles will also be routinely involved.

Barrel mustard bottles - based on glassmaker catalogs as well as authors empirical observations - are dominated by Individuals with three molded rings (aka staves, bands) above and below the central label spot, such as examples pictured in this article.  Other conformations ranging from two to at the very least six rings have also been observed along with some with vertical staves.  Most examples have rings which might be separated by a distinct space, like the instance previously mentioned still left.  Mustard was also packaged in other designs of ceramic and glass bottles (illustrations discussed underneath) although the barrel condition is considered the most closely connected to the solution (Switzer 1974; Zumwalt 1980).

Similar 20th century jars with the bead below the threads really seal over the rim (lip) by means of a metal lid Together with the rubber (or rubber-like) sealing surface area a lasting Element of the lid which is held set up by steel screw band.  The sealing compound over the lid would soften below heat while canning and adapt itself to minor irregularities on the jar rim furnishing a good seal (Creswick 1987).  These jars/closures had been significantly well-known starting inside the late 1910s and twenties and are still in use today.

Generally speaking, milk bottles really are a later on bottle type that did not likely exist to be a identifiable bottle "sort" until finally the 1880s.  In keeping with Bill Lockhart (New Mexico Condition University - Alamogordo, and also a noted authority on the subject) milk bottle creation went by four fairly recognizable levels of improvement (Lockhart pers. comm. 2005).  The 1st three phases pointed out down below are distinctly unique milk bottle production procedures discussed largely through the standpoint of cylindrical milk bottle creation.

These modest quantities are study wanting straight on within the rim rotating it, needless to say, so that the quantities are upright (click on and enlarge the image to the appropriate).

The "Lightning" design toggle or swing-type closures ended up really common for mouth-blown canning jars from ahead of patenting (for jars) in 1882 - the primary Lightning closure jars were reportedly made inside the late 1870s - until helpful hints finally very well into the 20th century on device-designed jars.  This critical closure form was invented and patented initial by Charles de Quillfeldt of New York City in 1875 although the style was meant to begin with for beverage bottles (Toulouse 1969a; Creswick 1987).

Bulbous/decorative formed sauces (not or else protected previously):  This group is quite wide with hundreds Otherwise a number of thousand unique versions that have in widespread only they had been employed for various sauces/condiments and don't suit very well while in the groups higher than.

The 50 percent-pint, device-manufactured (press-and-blow device) milk or product bottle pictured to the right has an ACL determining it as getting used through the Sunflower Dairy of Astoria, Oregon.  The bottle itself was produced by the Owens-Illinois Glass Firm at plant #22 in Tracy, CA. in 1944 most probably, as it's got a "four" day code without having a period of time (Lockhart 2004d).  For more images of this bottle click the next hyperlinks:  foundation see displaying the Owens-Illinois makers markings and a distinct valve or ejection mark; check out of the back again ACL label; shut-up of the original capseat cap.

The vertical side mildew seams gradually vanish about one/2" to 1" underneath The bottom on the end generating these bottles look - judging purely from these mould seams - for being mouth-blown by using a tooled complete (begin to see the box to the ideal To find out more on this phenomena);

With the mid-nineteen twenties, practically all ketchup bottles have been device-built and experienced possibly exterior screw thread finishes or some other re-sealable closure, like the Goldy.  Most have sided bodies such as Heinz patented bottle mentioned earlier mentioned.

Authors Take note: Recent observations of some Southern Glass Co. (La, CA.) made milk bottles exhibits that a lot of the earliest codes were (or integrated) an individual number about the rounded side of your end, not within the rim.  Exclusively, one particular example was noticed with only a "3" over the end side, no selection within the rim.  This was more than likely for 1923 although it could have been per month code (March) to get a bottle possible manufactured in that very same 12 months.

Quart PACIFIC / SAN FRANCISCO / GLASS Get the job done "Victory" jar - Click the picture to the ideal to check out the more compact (quart) version of the exact same form enhanced Mason jar explained earlier mentioned with fundamentally exactly the same embossing sample, similar producing attributes, and exact output time.

This style authorized wax, wax-dipped string, or other sealing compounds to become put in to the groove.  Whilst canning, a thoroughly sized round metal cap (generally tin) which has a turned down edge or "skirt" was then pressed into the warm wax to seal the jar.  Alternatively, the cap was very first positioned into the end, then hot wax poured to the groove to seal.
