To all whom it may camera."
Be it known that I, STEPHEN E. PARRISH, a citizen of the United States of America, residing at Hillsdale, in the county of Hills dale and State of Michigan, have invented certain new and useful Improvements in lnsulating'Jackets for lee-Cream Pails, of which the following is a specification, reference being had therein to the accompanying drawings.
lln the present state of the art ice-cream and other ices are extensively sold in paper pails and packages which latter have become an established article of commerce. These pails or packages are suitable for the carrying of the ice a short distance and where itis intended for immediate consumption, but they do not afitord any protection against the heat and consequently will not preserve the ice for any length of time. On the other hand where the ice is not intended for immediate use it is customary to pack it in salt and ice which greatly increases the bulk of the package as well as endangering the spoiling of the contents through leakage of salt water into the inner receptacle.
it is the object of the present invention to utilize the standard construction of paper pail or package and without materially increasing its size or weight to provide a heat insulation sufficient to preserve the contents for a much longer time.
- To this end the invention consists, first, in the combination with an ordinary paper an. pail or package of commerce, of a detachable, closely fitting heat insulating jacket and further in the peculiar construction of said jacket as hereinafter set forth.
In the drawings-Figure 1 is a perspective view of the jacket. Fig. 2 is a fragmentary vertical section of the jacket with the pail inclosed therein. Fig. 3 is a horizontal section through a portion of the jacket; Fig. t is a perspective view of elements used in the construction of the'jacket. 1F ig. 5 is a frag mentary perspective, view of the. cover; and Fig. 6 is a fragmentary perspective view of the inner paper receptacle.
lln the construction of my improved heat to linsulating jacket it is the object to secure the maximum efficiency with as little increase in the bulk of the package as possible and also with an inexpensive construction to manufacture. This I obtain by first forming an outer casin A preferably of paper or paper board an having at its upper end a metallic binding B. Within this outer casing is a lining C which ll preferably form of thin wood veneer and preferably of two bent sections, one forming the opposite sides C, C and the bottom C and the other the sides 0* C and an overlapping bottom C. These sections are arranged at right angles to each other and thus line the four sides of the receptacle. Between the lining U and the outer casing is interposed corrugated paper D which forms a series of air cells or pockets and holds the lining out of direct contactwith the outer casing.
E is a paper lining inside of the lining C and preferably rendered water proof by paraffin or other suitable'coating. The metallic binding B is preferably formed with a laterally bent portion F which forms a shoulder for supporting the cover of the package and also having a downwardly bent portion G which overlaps the lining E of the package.
H isthe cover preferably formed of a plurality of sheets of paper board H and interposed layers of felt H 1 are fastening devices for holding down the cover which as shown are formed by rods or wires having eyes lf slidably and pivotally engaging apertures in the binding B, while the opposite ends of the wires detachably engage apertures l in the metallic binding.
J is a ring for lifting the cover from the jacket, and K is a bail by which the package may be carried. p
The jacket constructed as just described is proportioned to fit the standard size of paper pail M which latter when inserted in the jacket will closely fit the same and will permit of placing the cover H in its proper position. In use the paper package M is first filled with the ice then inserted in the jacket, the cover is placed in position and is locked by engagement of the rods or wires T with the apertures 1?. This will effectually seal in the cold air which fills the cells or spaces formed by the corrugated paper, with the result that the conduction of heat through the walls of the jacket is very slow. Thus, even with a small package such for instance, as a pint pail, the ices may be kept in good condition for a number of hours.
l Vhat ll olaimas my invention is:
1. A heat insulating jacket comprising an inner and an outer wall, cellular spacing -means therebetween, a metallic binding having a return bent flange embracin the outer Wall, and a lateral portion exten ing across the space between the walls, and a cover for the jacket seated upon the laterally' extend- 5 ing portion of the binding.
2. A heat insulating jacket comprising a paper double walled receptacle, a metallic binding for the upper edge of the receptacle having a return bent portion embracing the 10 outer paper wall, and a lateral inwardly extending portion, a cover for the receptacle seated upon said laterally extending portion, and locking means secured to the binding strip for securing said cover to its seat.
- In testimony whereof I affix my signature 15 in presence of two Witnesses.
