SANITARY CONTAINER.

Application filed December 6, 1926'. Serial No. 152,860.

This invention relates to improvements in containers for edibles of that character which are intended to be eaten directly from the container by applying the mouth to one end of the container, and particularly represents an improvement over the device shown in our co-pending application for patent, filed December th, 1925, Serial No. 74,463. In this previous device, a sanitary 1 wrapper for that end of the container intended to be applied to the-mouth was provided in the form of a skirt surrounding the main body of the container at said end. This skirt was formed integral with the blank from which the container was made and was folded down onto the blank before the latter was rolled. This not only called for a folding operation apart from the rolling operation, but necessitated tearing all the thicknesses of the container and skirt completely through when unsealingthe normally closed end of the container, in order to then separate the skirt-from the body and allow the skirt to fall off. The above fea- -tures made the container relatively expensive to manufacture and necessitated the use of considerable strength to tear across the container when removing the sealing clip. This latter operation frequently caused the container to become distorted and warped before being put to its final and proper use.

The principal object of the present invention therefore is to eliminate the above defective features by providing a sanitary removable wrapper for the container so arranged that while formed integral with the blank from which the container is made, it eliminates the folding operation previously necessary, and does not require that the top 4 of the container shall be torn across when removing the sealing clip.

A further object of the invention is to provide an im roved form of sealing clip particularly a apted to this form of container and so constructed that it may be readily removed when desired without mutilating the container.

A further object of the invention is to produce a sim 1e and inexpensive device and yet one WhlCh will be exceedingly effective for the purpose for which it is designed.

These objects we accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a side elevation of our improved container, sealed.

. Fig. 2 is a view of the unrolled blank and extension from which the container and the sanitary wrapping are made.

Fig. 3 is a perspective of the removable sealing clip.

Referring now more particularly to the characters of reference on the drawings, the container is made from a. rectangular blank or sheet 1 of suitable prepared paper. The length of this sheet is equal to that of the finished container and itswidth is preferably about three times as great as the circumference of the finished container or so that the latter will have three complete turns or wrappings of paper in its make-up.

Along one side edge the sheet is formed with an integral extension 2 approximately half the heightof the sheet. Weakening means such as a row of perforations 3 is placed along the vertical line of junction between the sheet and the extension. The upper edge of the extension is alined with and parallel to the upper edge of the sheet. The initial portion A of the lower edge. of

the extension, from the sheet 1 outwardly,

is also parallel to said upper edge for a distance approximating one and a uarter wrappings aboutthe container. Sal ed c then slopes upwardly at an acute angle 0 the-horizon as at B to join the outer side edge of the extension, which is very short. The total width or extent of the extension is sufiicient to wrap about the container two or more times. A suitable adhesive 4 1s placed on the inner surface of the sheet 1' adjacent that side edge from WhlCh the extension projects and to the side of the row of perforations away from said extens1on.

The sheet is rolled on a mandrel in a suitable manner so that the extension Wlll be outermost. As soon as the main sheet is rolled the adhesive is moistened or applied so that the outermost vertical edge of the sheet will adhere to the wrapping thereunder. The extension is then wrapped around the container. The wrapping operation be ing completed the ends of the container are flattened or pinched together as at 5, and sealing clips are then applied to such ends. The lower sealing clip is a U-shaped member 6 of non-springy or bendable metal, which straddles the lower end Wrappings andis suitably pressed into place and then preferably indented to engage the paper as indicated at 7. This clip is never intended to be removed, and is applied last. The upper clip 8 is also U-shaped to straddle the upper end wrappings (which include the outer end portion of the extension 2) and when, applied to the container is indented as at 9 to grip the paper. This clip however also has central tabs 10 depending therefrom on both sides and normally lying adjacent the container. The clip 8 is applied first, while the container is still on the mandrel, so as to prevent the extension 2 from unwrapping. The contents of the container are placed therein from the lower end, which is then sealed by the clip 6.

When it is desired to open the container.

to consume or remove the contents, one or the other of the tabs 10 is pulled up and outwardly. This operation spreads the clip,

causing it to be disengaged from the paper and allowin it to be removed to expose the contents. T e extension member 2 not being secured to the main container wrappings along the top or down its side edge tends to unfold when thus freed from the clip, so that it may be then readily unwrapped for its full extent and torn olf along the line of perforations 3. The main container then remains unharmed and intact and its outer and upper portion will be in a perfectly sanitary condition, since up to this time such portion has been covered and enclosed by the extension. The lower edge of the extension being cut straight for the initial portion of its extent, it insures that all the perforations will be normally covered so that there is no chance for accidental tearing along such perforations before it is desired to remove the extension. The sloping edge of the re mainder of the extension forms a spiral when wrapped about the container, as shown in Fig. 1, this arran ement eliminating any tendency of said e ge to bulge outwardly so that it could be readily torn, as would be the case if said edge were parallel to the axis of the container.

From the foregoing description it will be readily seen that we have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practicesuch deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims. 2

Having thus described our invention what we claim as new and useful and desire to secure by Letters Patent is:

1. A container including a tubular body formed by a sheet of flexible material wrapped about itself, and an extension projecting from the outer side edge of the sheet wrapped completely about the body, said extension projecting downwardly from the top of the sheet to a. point short of the bottom thereof.

2. A container including a tubular body formed by a sheet of flexible mate-rial wrapped about itself, an extension projecting from the outer side edge of the sheet wrapped completely about the body, said extension projecting downwardly from the top of the sheet to a point short of the bottom thereof and adhesive material on the inner face of the sheet from top to bottom adjacent the junction of the extension therewith.

3. A container including a tubular body formed by a sheet of flexible material wrapped about itself, an extension projecting from the outer side edge of the sheet wrapped completely about the body, said extension projecting downwardly from the top of the sheet to a point short of the bottom thereof, means for causing the outermost portion of the sheet to adhere to the wrapping thereunder from top to bottom, and weakening means between the sheet and extension outwardly of the adhesive means.

4. A container including a tubular body formed by a sheet of flexible material wrapped about itself, an extension projecting from the outer side edge of the sheet wrapped completely about the body, said extension projecting downwardly from the top of the sheet to a point short of the bottom thereof, and weakening means along the junction of the sheet and extension.

5. A container including a tubular body formed by a sheet of flexible material wrapped about itself, an extension projecting from the outer side edge of the sheet wrapped completely about the body, said extension projecting downwardly from the top of the sheet to a point short of the bottom thereof, and weakening means alon the junction of the sheet and extension, theTower edge of the extension extending parallel to the top of the sheet for a distance greater than one complete wra ping of said extension whereby to normal y cover the weakening means.

6. A container including a tubular body formed by a sheet of flexible material wrapped about itself, an extension projecting from the outer side edge of the sheet wrapped completely about the body, saidextension projecting downwardly from the top of the sheet to a point short of the bottom thereof, and adhesive means along the junction of the sheet and extension, a portion of the lower edge of the extension sloping upwardly at an acute angle to a horizontal plane from adjacent the body toward the outer end of the extension.

7. A container including a tubular body formed by a sheet of flexible material wrapped about itself, an extension projecting from the outer side edge of the sheet wrapped completely about the body, said extension projecting downwardly from the to of the sheet to a point short of the bottom thereof, and a removable sealing clip to engage all the wrappings at the top.'

8. A container comprising a tubular body, one end of which is pinched in, a U shaped sealing clip to be placed over such end to enga e the same, and a bendable tab depending 50m one 'side of the clip to serve as a. meansfor spreading and prylng up the clip. 9. A container comprising a tubular body, a wrapping about the upper portion of said container and removably connected thereto only along the innermost vertical end of the wrapping, and means applied to the upper end of the container to seal the same and normally prevent unfolding of the wrapping.
