CONTAINER.

Application filed December This invention relates to containers for goods of different kinds, and especially for foods or confections of a yielding or plastic nature, such as soft candy, ice cream and the like.

The principal object of our invent on is to provide a sealed and fiexlble container for the purpose with sealing means at one end, of such a nature that the seal may be readily broken by the consumer and that end of the container will then present an open mouth having a cross area equal to that of the body of the container.

These two features enable the purchaser to obtain a free flow of the contents of the container, after the seal is broken or removed, by squeezing the container from the bottom toward the open mouth.

A further object of the invention is to form the container with a skirt around the mouth which drops off when the seal is broken, and the mouth opened. This insures that a perfectly clean and sanitary surface will be presented all around said mouth, and the consumer may place 4 his lips to sa1d mouth with perfect safety, regardless of possible unsanitary conditions surrounding the container previous to its sale.

These objects we accomplish by means of such structure and relative arrangement of parts as will fully appear by aperusal 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 view of the container of the approved sanitary form.

Fig. 2 is a view of the blank from whlch the container is made.

Fig. 3 is a similar view with the blank as initially folded and perforated, prior to the wrapping operations.

Fig. 4 is a cross sectional view on the line 44 of Fig. 1, looking upwardly, this view being of conventional form and before the mouth seal is applied.

. Fig. 5 is a side view of the container with a modified form of mouth sealing means.

Fig. 6 is a fragmentary view of the container with the mouth-seal partially removed.

Fig. 7 is a vertical enlarged section on the line 77 of Fig. 5.

Referring to the numerals of reference on the drawings, and particularly'at this time to 10, 1925. Serial No. 74,463.

the form of device shown in Figs. 1 to 4, we construct the container from a sheet 1 of paper of suitable grade, treated in any preferred manner to retard the permeation of moisture. The height of this sheet is whatever is deemed suitable for the container, while its width is preferably about three times as great as the circumference of the finished container, or so that the container will have three complete turns or wrappings of the paper, as shown in Fig. 4. This blank is formed along its upper edge with a rectangular extension 2, extending from one vertical edge of the paper and having a width about equal to 1%, or 1 turns of the paper when wrapped to make the container. Before the paper is thus wrapped, the extension 2 is folded over onto the outside of the sheet, as shown in Fig. 3. A row of perforations 3, or similar paper weakening means, is then cut through the sheet and extension along a line parallel to the top of the sheet and located somewhat less than half way down said extension. The length of this row of perforations is preferably equal to about 1 4 or 1% turns of the paper, and runs from the skirt toward the opposite vertical edge of the paper. Assumin as previously stated, that the container is ormed with three complete wrappings of the sheet, this insures that at least 1 turns of the sheet will be free of the perforations.

In wrapping the sheet, the imperforate portion thereof constitutes the innermost wrapping, so that the extension 2 is on the outside of the outermost wrapping, and forms a continuous skirt, overlapping itself for a certain distance, disposed about the upper end of the container. The sheet is preferably wrapped on a circular mandrel, so that the container 4 when thus formed will be circular in form. Sealing means of sides of the clip, and also by indenting the cli at intervals as at'7.

The contents are then inserted into the container from the bottom thereof; the lower end is then pinched in and a sealing clip 8, the same as the clip 6 is applied in the same manner. The container, with its contents sealed therein, is then ready for distribution to the retailer or for direct sale to the consumer.

To open the container, the same is held in one hand, while the clip 6 is grasped by the fingers of the other hand and given a lateral twisting movement. This will cause the wrapping of the body to yield along the line of perforations 3, where the paper has been weakened. The clip and adjacent portion of the paper being thus torn off, the lower portion of the skirt remains without any supporting connection with the wrappings of paper thereunder. The skirt therefore also drops off, exposing the adjacent body wrapping thereunder, and this exposed portion of the body, having been previously covered, will present a perfectly clean, fresh and sanitary surface to be engaged by the lips of the consumer.

The contents of the container are then squeezed therefrom, an operation which will cause the heretofore pinched-in mouth to open to its fullest extent.

The form of container shown in Figs. 5 to 7, is slightly cheaper to manufacture and is not so sanitary. If the container is used to carry individual pieces of candy or other articles which would be dispensed by tilting the container rather than by applying the lips to the mouth of the container, the lack of any exterior sanitary feature around the mouth of the container is no detriment.

The body 4 of this other type of container is formed of the same material, wrapped, and its ends pinched in, in the same manner as in the first described type. The skirt and' the weakening perforations are omitted,

however. The bottom sealing clip 8 is the same and applied the same way, as the correspondin clip on the first type. The upper or mout sealing clip 9, however, while of the same material and shape, extends beyond one side of the container to form a. finger lever. This clip is also sealed in place both by squeezing the sides of 'the same together and by means of indenting such sides at intervals as at 10. When it is desired to open this container, the outer end of the clip 9 is pried up, an operation which of course causes the opposite end of the clip to bear down on the paper thicknesses engaged by the clip. When the clip is thus pried up the indentations may cause one or more of the layers of paper to be torn through to the upper edge, as indicated at 11 in Fig. 6, but this will do no harm. When the clip is removed, the mouth of the c n ainer can not form a departure from the spirit of the" invention, as defined by the appended claims.

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

1. A container comprising a body sealed at the bottom, a. skirt formed integral with the body extending completely around the outside of the body at the top and disconnected therefrom except at the top, and a detachable sealing element applied over the top of the body and over the adjacent portion of the skirt, the latter projecting downwardly some distance beyond the sealing element.

2. A container comprising a body sealed at one end, a sealing element applied to the other end of the body, and adapted to be detached therefrom by a transverse and twisting tearing movement, and a skirt around the body adjacent but separate from the sealing element and partially surrounded and engaged by said element.

3. A container comprisin a tubular body formed of a blank of exible material wrapped about itself a plurality of times, an extension formed along the upper edge of the blank and folded outwardly thereof prior to the wrapping operations, said extension havin a width less than two Wrappings of the s eet, and a sealing element applied to the upper edges of the formed body and extending down only partially over said extension.

4; A structure as in claim 3, in which weakening means is applied to the extension parallel to the upper edge of the body and disposed outwardly of the sealing element.

5. A container comprising a tubular body formed of a blank of flexible material wrapped about itself a plurality of times, a sealing element applied to the upper edges of the formedbody, and a row of perfoskirt, and a sealin element apglied to said pings, and a rigid sealing element applied other end of the y and exten ing over the over the container at one end and engaging skirt only adjacent the fold thereof, said ll th wra, ing thereof; the outermost 1,e41,4oa a element being adapted to be detached by wrapping o the co tainer being weakened 5 a transverse twistlng movement tearing just below the sealing element.
