Lot 287: Jars. 3 plain and 3 embossed Newbon Improved Vacuum Seal Preserving Jars. 36 oz capacity. (Charles Davis Ltd., Hobart, Tasmania)

N/A. (N/A). Maybe some fine usage wear to the heel of some, but barely. Some light surface scratches and scuffs. A little wear and surface corrosion to the lids. One of the plain jars has a couple of tiny inner lip flakes. A little surface grime in places. One of the embossed jars has a small fisheye left of the N, there is a scuffed scratch up from this. Basically, these are all Near Mint or better!Great, Tasmanian jars! In 1931, Mr. H. Newbon of Lucaston patented a new fruit preserve which promised to revolutionise the preserving of fruit by housewives! (According to the article!). The system reduced the time, labour and cost of preserving fruit and vegetables by less than half compared with other systems. Messrs. Chas. Davis Ltd., of Hobart were among the first to get interested in the invention, after extensive testing to verify the statements, the purchased the distributing rights for the Commonwealth and immediately commenced manufacturing various sized outfits. In this initial article, it states that every outfit is supplied with Fowler's nottles and a sample of "New-Bon" fruit, which has been preserved by the "New-Bon" process. A 1932 article talks about the invention of new vacuum seal preserving bottles, stating that the special appeal of the prerving bottle is that by having a glass lid there is no metal to come in contact with the fruit or vegetables in the bottle. It is thought that this first batch of jars are the plain examples in this lot, which when you consider the base mark is exactly the same across both embossed and unembossed jars, but much blder on the unembossed jars, it does stand to reason that these were amongst the first to come out of the mould, hence being the oldest. 1933 advertising shows that these come in two sizes (we have sold both before), this larger size holds 36 ounces, the smaller size holds 29 ounces. An advert in the Huon Times on Thursday January 12th, page 2 extolls the virtues of these jars explaining that the screw cap ensures a perfect fitting lid, and is designed solely to exert a pressure on the lid until a vacuum is created. It has a corrugated grip. The glass lid overcomes the trouble of rusty metal lids which often contaminate the food. Glass is the only medium in contact with the food in the bottle. The rubber ring has been made flat so that it will make a perfect seal - it is impossible to twist, therefore ensuring a perfectly airtight bottle. The bottle is made in two sizes, the liberal width of which simplifies packing of food. The slot in the base allows water to circulate freely and is useful as a grip! The last advertising for these bottles was seen in March 1934. Great items, I haven't seen the plain examples before! Estimate: $100-150
