9 Claims.

This invention relates to containers for the packing or packaging of commodities, and pertains particularly to containers of the type which may be manufactured and shipped in knocked-down or substantially at condition and may be set up at the point of use. While not limited to such, it finds particular utility in the construction of such containers from paper board or the like.

A general object of the invention is the provision of an improved container structure which may` be completely fabricated at the factory, packed and shipped in knock-down condition in a space which represents only a small fraction of its volumetric capacity, which may be readily and quickly set up or assembled at the place where it is to be used or filled; which when so set up will constitute a secure, tight and strong container and protection for its contents.

A particular object of the invention is the provision of a container structure possessing the above mentioned characteristics and which may be manufactured at low cost.

Another object is the provision of such a container structure wherein the two end closures are interchangeable.

Other and further objects will be pointed out or indicated hereinafter or will be apparent to one skilled in the art upon an understanding of the invention or its employment in use.

For the purpose of aiding in a disclosure of the invention, we show in the accompanying drawing forming a part of this specification, and herein- 'after described, certain structural embodiments of it, but it is to be understood that these are presented for purpose of illustration only, as we are aware that' the invention may be embodied in other forms. Hence the present description and disclosure of the specific examples are not to be construed in any fashion calculated to limit the appended claims short of the true and most comprehensive scope of the invention in the art.

In the drawing, y Fig. 1 is a perspective view illustrating a cap or end closure for a container, parts being unfolded for the purpose of more clearly showing the construction; K l

Fig. 2 is a part elevational and part sectional elevational View of an end portion. of a container, same serving to illustrate the construction and assembled relationship of a cap or end closure and a tubular body portion; and

Fig. 3 is a perspective view, partly in elevational section, illustrating the construction and assembled relationship of a cap or end closure and a somewhat different tubular body portion.

(Cl. 22S-5.5)

The nature of the invention will be most quickly ascertained from the illustrative embodiments shown in the drawing, which will now be described. In the form shown, the container comprises a tubular trunk-or body portion and two 5 caps or end closures, the latter being identical or interchangeable, although it is to be understood that such interchangeability is not an essential feature of the invention.

The cap or end closure is shown in Fig. 1, in a l0 partly disassembled condition. It is formed of a sheet I0 of paper board or the like, which, for a cylindrical or frusto-conical container, is of approximately circular outline, its outer portion beingslotted to form tongues II, which extend in 15 generally radial directions from its central or body portion. A thin hoop I2, which may be made of paper board, rests upon the end sheet I0 in concentric relationship therewith, and the tongues II, which are spaced from one another 20 by flaring notches, are bent up against the outer s ide of the hoop I2, over the rim thereof and downwardly against the inner side of the hoop. The intervening notches are so proportioned that when thus folded about the hoop, the tongues 25 abut one another margin to margin. Preferably the tongues are fixed individually to the outer and inner sides of the hoop by adhesive, although such fastening of the tongues is not essential. The end portions of the tongues, designated IIa, 30 which rest against the inner. side of the hoop, form an inwardly projecting ledge or shoulder, as shown in Fig. 2.

The container side or trunk member I4 is a tube or sleeve of exible material, such as paper 35 board, and preferably is formed with longitudi' nal creases I4, as in accordance with the disclosure in our co-pending applicationA Serial No. 644,809, filed November 29, 1932. It is adapted to be collapsed to substantially flat condition, or 40 set up in a substantially cylindrical form.

To provide for the connection of the end closure with it, the trunk member may be provided at its end with a narrow peripheral strip I5, secured by adhesive to its outer side and pro- 45 jecting therefrom as a shoulder or ledge. The width of this strip I5 is slightly less than the space between the margin of the ledge IIa and the end sheet Ill of the end closure. The external diameter across the strip I5 being somewhat greater than the internal diameter across the ledge IIB, and the end of the trunk member being inserted within the cap or end closure, the margins of the strip I5 and ledge IIa will be brought to an overlapping relationship, as illus- 55 trated in Fig. 2, and an effective'connection of the end closure to the trunk member provided. It is to be observed that this method of connection may be employed at either or both the top and bottom ends of the container. It is apparent also that the hoop I2 may be either of cylindrical form, or of frusto-conic form aring toward the end sheet I0.

In Fig. 3 is illustrated another arrangement for connection of the endA closure to the trunk member, which arrangement may be most advantageously employed for the connection of the bottom end closure. It will be seen that the tubular trunk member I4 is provided at its lower end with a plurality of tongues I6 and short longitudinal slots I'I. Such construction of the trunk member is described in more detail in the application identified above. An end closure of the above described construction being provided, the trunk member is inserted within the hoop, the tongues I6 being turned radially inward so as to rest upon the inner surface ofthe end sheet I D. Then a wedging disk I8, of a diameter somewhat greater than the internal diameter of the trunk member, is pressed down into the latter and within the compass of the hoop of the end closure. When it passes the ledge I Ia, the wedging disk I8 will spring the portions of the trunk member wall between the slots I'I outwardly to positions below the ledge, and hold them securely wedged in that location against the inner side of the hoop I2. So assembled, the ledge I la, overhanging .the outwardly wedged portions of the trunk member wall, will hold the trunk member against withdrawal from the hoop.

It will be appreciated from the foregoing that identical end closures may be used to form a bottom construction such as illustrated in Fig. 3 and either a bottom or top construction as illustrated in Fig. 2.

Depending on the manner in which they are folded and secured, the portions of the tongues at the outer side of the hoop member may either conform to the curvature thereof, or may be straight, or more nearly straight in the circumferential direction. Consequently, the peripheral contour of the end closure may be either approximately circular or polyhedral. The hoop member holds the tongues against separating or flaring, and the tongues, by virtue of their marginal abutment one with another, reinforce the hoop member against collapsing.

The construction provides a secure and strong container which may be manufactured economically, packed for shipment in a space which is quite small as compared to its capacity, and which may be set up very easily at the place where it is to be illed.

What we claim is:

l. In a container, an end closure comprising a hoop member and an end sheet covering and closing one end thereof and having marginal tongues folded across the outer side and margin of the hoop member and with their extremities turned in against the 'inner side thereof, and a exible tubular trunk member having its end portion extending within the hoop member and provided with a peripheral shoulder interposed between the end sheet and the in-turned extremi- 'ties of the tongues.

2. An end closure for a container, comprising 10 a hoop member, and an end sheet having a body portion covering and closing one end thereof and having marginal tongues folded across the outer side andmargin of the hoop member and with their extremities turned inwardly against the inner side thereof and terminating at a distance from the body portion of the end sheet to afford an intervening channel.

3. An end closure as specified in claim 2 and wherein said tongues are secured individually to the hoop member.

4. An end closure as specified in claim 2 and wherein said tongues are disposed in marginal abutment with one another and are secured to the hoop member.

5. A container comprising the combination with an end closure as specied in claim 2, of a flexible tubular trunk member having an end portion extending within said hoop member, and a wedging disk holding portions of the trunk member wedged outwardly between the body portion of the end sheet and the extremities .if the tongues.

6. An end closure as specified in claim 2 and wherein the peripheral contour afforded by the tongues about the hoop member is approximately circular.

7. An end closure as specified in claim 2 andv wherein the contour afforded by the tongues about the hoop member is polyhedral.

8. In a container, the combination with a tubular trunk member having an outwardly jutting peripheral portion adjacent its end, of an end closure comprising an end sheet having a body portion covering the end of the trunk member and marginal tongues bent angularly from the plane of the body portion and their ends turned reversely so as to extend toward the body portion but terminating at a distance therefrom to afford an intervening channel, and a hoop member enfolded by said tongues and holding them against flexion away from the trunk member, the outwardly jutting portion of the trunk member being disposed in said channel.

9. In a container, a construction as specified in claim 8 and wherein the lateral margins of the juxtaposed tongues are contiguous to one another.
