CONTAINER Filed May I24, 1941 J] I .Zivvsmrar? Patented Dec. 28, 1943 CONTAINER John Haycock, Larohmont, N. Y., assignor to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application May 24, 1941, Serial No. 395,107 1 Claim. (Cl. 229-45).

The present invention relates to new and useful improvements in containers, and more particularly to improvements in a container having at least the body portion thereof formed from paper or other fibrous material, such as fibre board, pulp board, or the like.

According to the present invention, the container includes a body portion which is preferably cylindrical and which is formed from a fibrous material in any suitable manner, as by spiral or convolute winding. The body portion is preferably provided with an outer wrapping of moisture-proof fibrous material which may be convolutely applied thereto and which extends from one end of the body portion to a point spaced inwardly of the opposite end thereof so as to leave a limited part of the body portion exposed. This exposed part of the body portiongs adapted to be closed by a slip cover which is preferably in the form of a metal friction closure member having a depending flange. The opposite end. of the body portion is preferablyclosed by a metal end which houses and is clinched on the body portion and the wrapping.

An object of the present invention is to provide a container of the above type wherein the slip cover includes a depending flange frictionally engaging the exposed outer surface of the body portion and which abuts and is substantially co-extensive with the adjacent edge of the outer wrap- 3 ping so as to present a smooth and even outer surface at the abutting edges over which a sealing tape or label may be applied.

Another object of the invention is to provide a container of the above type wherein the slip cover is shaped to provide an annular recess around the edge thereof and opening downwardly so as to receive and frictionally engage the adjacent end of the fibrous body facilitate the addition of a suitable form of seal lng material at the end of the body portion.

A further object of the invention is to provide a container of the above type wherein the cover, flange is provided with an outward peripheral rib of substantially the some external diameter as the opposite end closure so as to facilitate manipulation of the container in order to apply the sealing strip or an outer label over the abutting edges of the cover and the outer wrapping.

The above and'other objects of the invention will in part be obvious and will be hereinafter more fully pointed out.

In the accompanying drawing:

Figure l is a longitudinal sectional view showing the body portion separated from the end closure members.

Figure 2 is a similar longitudinal sectional view showing the body portion assembled with the end closure members and with a sealing tape applied around the removable cover member.

Figure 3 is an enlarged fragmentary sectional view showing the sealing tape applied over the cover flange and the outer wrapping for the body portion.

Figure 4 is a similar enlarged fragmentary sectional view showing a modification wherein the sealing tape is replaced by an outer label extending over the entire body portion and cover Referring more in detail to the accompanying drawing, the body portion ill of the container is formed of fibrous material which may be spirally or convolutely wound into cylindrical shape. An outer wrapping H of moisture-proof material is wound around the body portion and extends from the bottom end to a point below the opposite or upper end of the body portion, thus leaving an exposed portion Illa on the body portion immediately above the upper end of the wrapping ii.

The bottom end closure for the container is preferably in the form of a metal disc l2 havingan inwardly extending wall portion l3 which' merges into a central depressed closing portion 0 H. The end of the wall portion l3 merges into an outwardly extending flange portion ii, the end of which is inwardly turned as at it. This end closure i2 is applied to the container in the manner illustrated in Figure 2. Thus, the outer surface of the wall portion 13 engages within the end of the fibrous body portion l0 and the flange portion l5 extends across the bottom edge of the portion and so as to body portion. The outer end portion of the flange I5 is turned upwardly and inwardly so that the inturned edge It will clinch the outer wrapping II and compress the fibrous body portion l0 against the wall portion iii. In this manner, an air -tight seal is provided between the body portion and the end 12 and a suitable sealing com pound may be employed if desired.

The closure member for the opposite or top end of the bodyportion is in the form of a metal slip cover which includes a horizontal depressed closing portion I1 and an inner upwardly extending wall portion l8 which merges into a substantially horizontal portion I9. The horizontal portion I9 is turned downwardly to provide a depend ing flange portion 20 which is shaped to provide an outwardly extending rib 2| near the upper end thereof. The inner surface of the wall portion I 8, the horizontal portion l9, and the depending flange 20, provide a downwardly opening annular recess or chime 22 within which a suitable packing or sealing material 23 may be placed. As shown in Figure 2, the slip cover is applied to the body portion and the parts are so dimensioned that the bottom edge of the cover flange 20 will abut against the adjacent upper edge of the outer wrapping H. The thickness of the wrapping II and the thickness of the flange 20 are substantially the same so as to provide a smooth and even outer surface around the abutting edges. The upper end of the body portion ID will be positioned within the recess 22 so as to provide a friction seal to eliminate air. As a further seal, the packing material 23 engages the outer end of the body portion beneath the horizontal portion l9 on the cover.

The outer diameter of the rib 2| is substan tially equal to the outer diameter of the bottom closure member i2 so that the assembled container can be conveniently rolled or otherwise manipulated to facilitate the application of a sealing strip or tape 24. This tape 24 is applied over the outer surface of the cover flange and the adjacent outer surface of the wrapping ll so as to seal the abutting edges therebetween. While the tape 24 provides an additional seal for the contents of the container, this tape also provides a means for indicating whether there has been any unauthorized tampering with the container. The tape must be broken before the slip cover can be removed so that there is provided a tamper-proof container.

In place of the sealing tape 24, it is desirable in some instances to apply an entire outer label 25 which extends over the outer wrapping I l and also over the cover flange 20 below the rib 2|. Such a label may also serve to seal the abutting edges between the wrapping Ii and the cover flange 20 and to provide a tamper-proof? container and the bottom of the label is clinched by the inturned edge I6 on the flange I5 of the bottom closure. Alternatively, as shown in Figure 4, the label 25 may be provided with perforations 2B in the region of the abutting edges between the cover flange and the wrapping i I. With this construction, any breaking of the label will indicate unauthorized opening of the container and these perforations 26 also serve to facilitate removal of the slip cover, when desired. In both forms of the invention, it will be seen that the sealing tape 24 and the label 25 are disposed immediately below the rib 2| in order to protect the same against tearing. The rib 2| also provides a grip for facilitating removal of the slip cover.

It is to be clearly understood that minor changes in the details of construction and arrangement of parts may be made without departing from the scope of the invention as set forth in the appended claim.

I claim:

A container comprising a cylindrical body of fibrous material, an outer wrapping around the body portion and terminating short of the upper end thereof, said wrapping extending all the way to the lower end of the body portion, a metal bottom end shaped to provide a channel to receive the lower end of the body wall and provide a flange extending along the outside of the body wall, the free edge of the flange being beaded and imbedded in the body wall, a metal slip cover having a channel adapted to receive the upper end of the body wall, and a depending flange abutting against the upper edge of the body wrapping, said flange being of substantially the same thickness as the wrapping and having a bead therein adjacent the upper end of said depending flange, said bead being of substantially the same diameter as the outer portion of the beaded end of the flange on the bottom end and a sealing strip overlying the abutted edge portions of the cover flange and the wrapping for securing the cover to said body for sealing said container.
