Application tiled March 2', 1926. Serial No. 91,833.
This invention relates to improvements in sterilizers, and has particular reference to a sterilizer for use in the cleansing of bottles such as nursing bottles, fruit and the like.
Another object of this invention produce a device of this character in a plurality of bottles may be placed, sterilized and removed from the sterilizimgk liquid without injury Vto the person using the same.
Another object is to produce a device of this nat-ure which is cheap to manufacure, and therefore well within the purchase price of the average user.
A still further object is to provide means whereby a plurality of nipples may be also sterilized at the same time.
Other objects and advantages will be apparentduring the course of the following description.
In the accompanying drawings forming a part of this invention, and in which like numerals are used to designate like parts throughout the same,
Figure I is a vertical cross-section showing my device in use as the same would ap.- pear when sterilizing the contents of the bottle,
Figure II is a top plan view ofthe retaining plate, l
Figure III is a top plan view of the bottle rack, and
Figure IV is a view similar to Figure I showing the bottle and rack in an invert-ed position so as to sterilize the interior of the bottles.
At the present time, in the preparing of formula milk, it isV first necessary to thoroughly cleanse the bottles by immersion in boiling water, then the bottles must be removed, drained, cooled and filled with the milk, after which the bottles are again placed in a vessel containing water, heated to a predetermined temperature, and then Quickly cooled in order to Pasteurize-the is to which Y milk within the bottles.
The sterilizing of the bottles in an Ordinary vessel requires time in placing the bottles in the vessel, with the danger of burning the hands when removing the bottles from the water, also in sterilizing the nipples the same float upon the surface oftentimes, and are therefore not properly sterilized, and when they drop to the bottom of the vessel they are extremely difficult to extract from the water, besides being diticult to locate. Y
I have therefore provided a bottle holding rack which will obviateall of the above di'liiculties and disadvantages. f Inthe accompanying drawings wherein for the purpose of' illustration is shown a preferred embodiment of my invention, the numeral 5 designates a vessel, within which I place a rack constructed with a plurality of tip-rights 6. This rack is preferably formed of wire. These uprights 6 are con- .n'ected to a ring T, which ring is in turn provided with a bail 8. The bottom of the rack is formed with a plurality of spokelike T members 9 which oin the uprights 6.
At 11 and 12 I have shown vertically dirposed wires which are connected to a ring 13. Between these wires 11 land 12 I position a receptacle 14 within which nipples must be placed after which a screen cover 16 is secured to a wire ring 13.
At 17, I have shown a retaining plate having ears 18 and 19 which are adapted to engage the ring 7, while at 2l I have prof vided a spring catch which is also adapted to engage the ring This retaining plate 17 is provided with a plurality of openings 22 through which the necks of the bottles to lbe sterilized may pass.
The manner of using my device is as follows Assuming that the rack is in the position shown in Figure I, the retaining plate 17 is removed, the bottles are placed within the rack and the retaining plate replaced.
The bottles are now filled with water and the receptacle 5 is also partially filled with Water. By now quickly inverting the entire rack and dropping the same into the vessel 5 the water will be retained in the bottles and the rack and the bottles will assume the position shown in Figure IV. After the water has reached a boiling point, the ent-ire rack may be lifted out of the' vessel by employing a hook 23 and engaging one of the with the formula milk and the necks plugged with Cotton. The rack may now be reinserted in the vessel and the water gradually brought up to tlre desiredv degree of heet.
It will thus be seen that by employing` my rack it is not necessary totoueh the bottles filter they have once been placedin the rack. After the milk has been Pasteurized the entire rack may be removed from parts niziy be resorted to without departing?v from the spirit of the invention or the scope ol the subjoined claim.
Having thus described my invention, I claim: A 1
Irl ai device ofthe Character described, :t plurality of vertically disposed' members, a ring secured to the upper extremity of said vertically disposed members, e plurality or' spoke-like members' connecting to the lower extremity `of said vertically `disposed members, said spoke-like members converging and joining at a centrelpoint7 uprights secured to said spolrelilre members, e? .ring secured to said last mentioned. uprb screenremovwbly secured to said lust men-- tioned ring, as and for the purpose .de scribed. y l A y In testimony Whereoiieix my signetuic.
