7 Claims.

This invention relates in general to containers comprising a stiff outer body and a thin, flexible bag suspended within the body.

Containers for all kinds of food products, greases and oils, syrups etc., are now being made with a comparatively heavy stiff paper body with a bag of thin, flexible material, such as cellophane, suspended in the body. In such containers, the bag is usually formed and placed in the body. The contents are then placed in the bag, and the top of the bag sealed by a suitable closure. In some instances, the closure is also of paper-board, and in other instances it is a metallic closure. If a paper-board closure is used, it is usually secured to the mouth of the bag by means of suitable adhesive. The metallic closure is usually crimped into contact with the mouth of the bag. In some cases, after the bag and the closure have been united, they are removable as a unit from the body to provide inspection of the goods through the transparent bag without breaking the seal of the bag.

An object of this invention is a container construction whereby the bag is detachably suspended in the body of the container previous to the filling of the bag and its joinder with the closure, and by which construction the bag is sufliciently secured in thecontainer to prevent accidental displacement during shipment and the handling of the container during the filling operation.

A further object of the invention is a container provided with an inner bag of thin, flexible material, and a detachable supporting unit for the bag. The construction of the supporting unit being such as to not add materially to the over-all dimension of the container.

A further object of the invention is a fibrous container provided with an inner bag lining, a detachable bag supporting unit, and a metallic discoidal closure for the bag, the construction of the supporting unit being such as to permit the use of a metallic closure of minimum diameter.

The invention consists in the novel features and in the "combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a side elevation of the complete container with parts broken away, and parts in section.

Figure 2 is an exploded view of the parts and relative position for assembling.

Figure 3 is a fragmentary, sectional view with the lining bag partly in elevation, and with the closure preliminarily attached to the bag.

The structure of the invention comprises a rigid cylindrical body, a bag of thin, flexible material mounted in the body, a cylindrical rin complemental in diameter and wall thickness to the body, a second ring member encircling the first ring and depending below the lower edge of said first ring to encircle the body adjacent the top edge thereof, the mouth of the bag being secured between said rings, and means for securing said rings together.

l9 designates the wall, or body, of a container which may be of any suitable form, size and construction. As here shown, the body it) is cylindrical in form and is made of comparatively heavy paper-board, or like material, and is provided with a suitable bottom ll.

[2 designates a bag formed of thin, flexible and preferably transparent material, such as cellophane, and is of such size and form as to be received within the body ID with the open end of the bag extending an appreciable distance above the top edge of the body. It will be understood that the bag 12 is filled while arranged in the body l0, and is thereafter provided with a suitable closure. It has been found preferable to simultaneously form and insert the bag l2 in the body Ill where itremains during shipment, and until the contents 0. thee'container are placed in the bag. It is accordingly desirable that some means or construction be employed to maintain the bag in proper condi-' tion in the body l0 during shipment and handling of the container, and suitably support the bag while the contents are being placed in the bag and while the closure is being sealed to the open end of the bag. It is further desirable that the sealed bag and contents be readily removable from the container so that the contents of the bag may be inspected without breaking the seal of the bag.

As here shown, this means comprises a ring member l3 which is complemental in wall thickness and diameter to the barrel H] of the container. In practice, the barrel ID of the container consists of a section of a paper tube which is formed by a continuous winding process well known to those familiar with the art, and the ring l3 consists of a section of the same tube. The ring I3, in operative position, rests upon the upper edge of the barrel l0, and the upper edge of the bag l2 extends over the upper end of the ring I3 and down the outer surface of the ring l3 for a short distance, as at M. A second ring 15 encircles the inner ring l3 with the upper end of the ring l5 spaced slightly below the upper end of the ring [3 and with the lower portion of the ring l5 overlapping the upper end of the barrel ID, as indicated in Figures 1 and 3. The free end M of the bag I2 is secured between the rings l3, I5, in any suitable manner. For example, by means of suitable adhesive and preferably, the rings I3, I 4 are secured together as at I6 by adhesive.

In the fabrication of this container the ring I3 may be placed upon the top edge of the barrel III. The bag I2 is formed and simultaneously inserted in the barrel I0 with the upper edge of the bag extending over the upper end of the ring I 3 and downwardly over the outer surface of the ring which has been previously coated with adhesive. The ring I5, the upper inner surface of which is also coated with adhesive, as at IT, is sleeved over the ring I3 and the outward depending portion I4 of the bag I2, with its upper end slightly below the upper end of the ring I3. The rings I3, I4, form a support for the bag I2 which is detachably secured to the barrel III in the manner of the well known slip cover. The bag It) is thus retained in the body of the container, and the contents may be inserted in the bag and subsequently a closure secured to the open end of the bag.

As, here shown, the closure l8 consists of a. metal disk with its peripheral margin extending upwardly and outwardly as at I9-20, and the periphery formed with a bead 2|. The diameter of the upwardly extending portion I9 of the closure is such as to permit the closure to be pressed snugly into the open end of the bag when assembled to the rings I3, I5, The outwardly extending portion 20 is subsequently rolled over the upper edge of the ring I3 and bag I2, and the bead 2| crimped inwardly, as shown to the left, Figure 1.

It will be observed that the over-all diameter of the container is only increased by the thickness of the outer ring I5, and further that standard closure disks may be used due to the fact that the inner ring I3 is of the same dimensions as the body of the container. Heretofore, the construction of the detachable bag supporting units has been such as to require a closure of greater diameter than ordinarily used with the container when the bag is not employed. With my construction, the standard disk closure is employed thereby saving a considerable amount of metal in the closure. The container is fabricated and the closure is preliminarily pressed into the open end of the container, as indicated by dotted lines Figure 3. This permits shipping of the container and keeping the inside of the container clean and sanitary.

When the container is to be used, the closure I 8 is removed and after the contents have been placed in the bag I2, the closure is replaced and the peripheral margin of the same is seamed over and secured, as indicated in Figure 1.

This construction generally aflords a rigid and practical support for the bag I2 and the contents therein, and permits the bag to be readily removed from the container for the purpose of inspecting the contents of the bag. Attention is also called to the fact that the upper end of the bag hangs straight downwardly from the upper edge of the inner ring I3, there being no offsets or inwardly extending projections on the inside of the container to damage or crack the bag.

What I claim is:

1. A container comprising a cylindrical casing of substantially rigid fibrous material, a ring member mounted upon the upper end of the casing and arranged coaxial therewith. a second ring member encircling said first ring member and the upper portion of the casing, a bag of thin, flexible material arranged in the casing with the open end of the bag secured between said ring members, and a closure for the bag secured to said first ring member.
