March 11, 1930. R. G. WICHNER PROTECTING CONTAINER FOR BUTTER TUBS OR THE LIKE Filed larch l, 1928 I awenlor M'cmz r (Thu Patented Mar. 11, 1930 UNITED STATES ROBERT Gr. WICI-INER, OF COLOMA, WIfiCONSIN PROTECTING CONTAINER FOR BUTTER'TUBS OR THE LIKE Application. filed March 1, 1928. Serial No. 258,320.
The present invention relates to containers adapted particularly for use as an insulating protector for butter tubs or the like whereby to prevent direct exposure of the tub, or the contents thereof, to the atmosphere.
predetermined manner is adapted to form the walls of a cylindrical container, as well as the top and bottom cover for forming a closure for the opposite end thereof.
A still further object is to provide a protecting container of this character of a simple and practical construction, which forms an entire enclosure for the tub, which is relatively inexpensive to manufacture, easy to arrange in position and secure of itself on the tub and otherwise well adapted to the purposes for which the sameis intended.
Other objects and advantages reside in the special construction, combination and arrangement of the various elements forming the invention as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout.
In the drawings:
Figure 1 is a perspective view of the completed container in closed position,
Figure 2 is a vertical sectional view therethrough, I t
Figure 3 is a fragmentary transverse sectional view taken substantially along line 3-3 of Figure 2 and Figure. 4 is a plan view of the blank from which the container is formed.
Referring now to the drawing in detail, the invention comprises a protecting container for butter tubs or the like including a substantially cylindrical body section 5 adapted to encircle the walls of a butter tub, in a manner as shown by the dotted lines indicated at 6 in Figure 2 of the drawing, each end of the body portion being closed by top and bottom cover sections 7 and 8 respectively.
The body and top and bottom cover sections are formed from a like sheet of material, of a shape as clearly shown in Figure 4 of the drawings, and in order to provide for the slightly tapering shape of the body portion 5, the portion of the blank from which this body portion is formed is of an arcuate shape, with the top and bottom cover sections extending from its opposite edges intermediate its ends in the form of projections.
As best shown in Figure 3 the sheet of material alluded to is made up of inner and outer layers and an interposed corrugated layer whereby air pockets are formed in the sheet of material. From this it follows that the said sheet of material is possessed of insulating capacity and is also possessed of cushioning capacity.
One end of the blank from which the body portion is formed, is provided with a strip of tape 9, preferably formed of cloth or other relatively strong material with its outer edge extending outwardly beyond the adjacent end of the body portion 5. The face of the tape strip 9 disposed against the end of the body portion 5 is provided with an adhesive or other suitable substance adapted to enable the tape to be firmly secured to the body portion, so that when the opposite end of said body portion is brought into end to end relation against the end thereof carrying the tape, said tape will lie in overlapping relation with respect to each of said ends and serve to firmly secure the same together whereby to form the cylindrical body portion of the container.
The diameter of the extensions forming the top and bottom cover sections 7 and 8 is en larged over the diameter of the respective ends of the body portion of the container, whereby to enable the edges of the cover sections 7 and 8 to be crimped in the form of flanges 10, disposed outwardly of the walls of the body portion, at each end thereof, in overlapping relation with respect to the top and bottom edges thereof. The relative area of the respective cover sections 7 and 8, as compared with the total area of the extension from which said cover sections are formed, is clearly shown by the curvilinear dotted lines in Figure i.
The flange 10 thus formed about the edges of the respective cover sections not only assist in retaining the covers in position upon the body portion, but also protect edges of the body portion and prevent the separation of the connected ends thereof.
The material from which the container is made is preferably of a double thickness, with the layers thereof arranged in spaced rela- 10 tion, as clearly indicated in Figure 3 of the drawings, whereby to form an air space with the layers of the material.
By constructing a container in this manner the butter tub enclosed within the same is 15 Well protected from direct contact with the atmosphere and the contents of the tub are thus preserved in a better state.
It is obvious that my invention is susceptible to various changes and modifications in :0 construction without departing from the spirit of the invention or the scope of the appended claim, and I accordingly claim all such forms of the device to which I am entitled.
g5 Having thus described my invention, what I claim as new is: 7
An insulating and cushioning protective container for a tub of circular cross-section, formed of a sheet of material having spaced 0 layers and a corrugated member interposed and forming air pockets between the said layers; said sheet of material being adapted to snugly surround a tub and have its ends conuected together, and said sheet of material 15 having top and bottom cover portions adapted to be opposed to the top and bottom, respectively, of a tub and flanged against the side of the sheet, whereby the sheet is adapted to be secured of itself on a tub without the asa sistance of extraneous means and when the sheet is so secured the tub is completely closed, insulated and protected.
In testimony whereof I afiix my signature.
ROBERT G. VVICHNER.
