Fig. 6 is a View similar to Figs. 2 and 5 showing still another form of the invention.

For the purpose of illustrating the application of my invention, I have shown a container iii which is constructed with a Wall structure It best illustrated in Fig. 2. The container is open at the top as indicated at E2 and is closed at the lower end thereof through a bottom, not shown. Inasmuch as the particular construction of the container forms no feature of the invention, the same has not been described detail in this application, though it can readily be comprehended that any suitable construction such as is now well known in the art may be employed.

The open end it of the container it is closed through a cover it (Figs. 2 and 3). This cover is constructed wtih a body portion i l which covers the open end [2 of the container and is further constructed with a flange i5 which extends downwardly from the body portion and along the wall i i of the container.

' A hoop l6 encircles the upper end of the wall structure it of the container proper and is rigidly secured thereto. Where the container is constructed of paper, hoopit may be likewise constructed of paper and glued to the wall structure ll. Where other forms of construction are employed, the hoop may be constructed in the customary manner and secured to the wall structure in any suitable manner. The hoop it is formed with a downwardly facing shoulder ll by means of which the cover it is held attached to the container proper.

Distributed about the periphery of the cover a5 l3 are a number of fastener members I8, [9, 20, and 2|. All of these fastener members being identical in construction, only the fastener member 2! will be described in detail. This fastener member is shown in detail in Fig. 4iand is constructed from a length of resilient flat ribbon or a metal strip which is formed in the desired shape by bending. This fastener member consists of a part 22 which is adapted to be imbedded in the flange E5 of the said cover. Another part 24 depends from the part 23 and is formed at its extreme end with a looped portion 25 which forms an eye and an abutment 21 at the upper end thereof. When the cover is applied, part 24 follows along the lower portion of the hoop it which is considerably longer than the flange l5 and the abutment 2'? extends beneath the shoulder ll engaging the same and holding the cover attached to the container.

The cover I3 may, if desired, be constructed from sheets of paper glued together and pressed in suitable dies to form the body portion 14 and flange l5. When the cover is so constructed a number of sheets from which the same is formed are first placed one upon the other with a suit able adhesive therebetween. The fasteners l8, i9, 20, and El are next placed upon the sheets so disposed and the remainder of the sheets placed upon these fasteners. Thereafter the composite structure is pressed in suitable dies toform the body portion 14 and flange l5 and the formed cover allowed to set and dry. When properly cured an extremely rigid and substantial cover construction results in which the fasteners are firmly imbedded. When the cover is so constructed the parts 22 of the fasteners become irnbedded in the body portion M of the cover and the parts 23 in the flange 25.

In the application of the cover to the container the following is the procedure. The parts 24 of the various fasteners are normally bent inwardly as best shown in Figs. 2 and 3. In applying the cover to the container the cover is placed upon the open end of the container with the looped portions 25 resting upon the upper edge 23 of the hoop l6. Due to the fact that the portions 25 are circular in form the lower edges 29 thereof are curved and operate as cams which engage the corners of the upper edge 28 of the hoop l6 and causes the parts 24 of the fasteners to spread outwardly and allow the looped portions 25 to follow along the outer surface 39 of the hoop i5. When these portions come below the fastener H of hoop E6, the resiliency of the parts 24 of the various fastener members cause the said looped portions to spring beneath the shoulder fl and to bring the abutments 2'! into engagement therewith. 'The parts are so disposed that when the abutments 21 engage shoulder H, the under surface 3| of body portion ll! of cover I3 rests upon the upper edge 28 of the hoop 16.

After the cover has been applied, as described, the same is temporarily held in place through the action of the abutments El and may be removed by the insertion of the fingers beneath the looped portions 25 of some of he fasteners and the bending of the portions 24 of said fasteners outwardly to permit said eyes to clear the hoop 6. The cover 53 may then be raised upwardly at such locality and the procedure completed until sufficient of the fasteners have been disengaged to permit of the removal of the cover from the container.

For the purpose of permanently holding the cover 13 applied to the container, a retaining member 32 is employed which may consist of a piece of wire which is successively threaded through the various eyes 26. The ends of this retaining member are twisted together as indicated at E2. Retaining member 32 becomes lodged beneath the shoulder ll of hoop I6 intermediate the fastener members l8, I9, 20, and 2! and is firmly seated against the outer surface 34 of the wall structure I l of the container proper. When the retainer member 32 is so disposed, the same serves to restrain outward movement of the various fastener members and prevents disengagement of the abutment 21 from the shoulders 37 of the hoop Hi. In this manner the cover is firmly held attached to the container proper and accidental removal of the same prevented.

If desired, the portions 22 of oppositely disposed fasteners may be formed continuous and may extendcornpletely across the body portion E4 of the cover l3. Such construction is shown in Fig. 4 which illustrates two straps '35 and arranged to cross one another and con-fined within the body 14 of the cover proper. These straps are provided at their ends with downwardly projecting parts 31 similar to the parts 23 and E4 of the form of the invention shown in Fig. 3. At the ends of these parts are provided looped portions 38 identical with the looped portions 25 and which serve the same purpose. In the form of the invention shown in Fig. 2 it becomes impossible to pull the fasteners out of the cover. At the same time the

straps

35 and 36 operate to stiffen and reinforce the cover and to prevent breakage thereof when the containers are stacked one upon the other.

In Fig. '5 I have shown another form of the invention which is quite similar to that shown in Fig. 3. In this figure corresponding parts will be indicated by the same reference numerals as in the other form of the invention. The fastener illustrated in Fig. 5 is indicated in its entirety at 39 and is provided at the part 23 thereof with an inwardly extending finger 48 which is adapted to engage beneath the shoulder H of the hoop !6. At the end of the finger 4!! is provided an angularly disposed part M which serves as a cam the same as the part '29 of the looped portion 25 and operates to spread the fasteners apart when the cover is being applied "to the container. Between the finger "40 and the part 4! is formed a bight 42. The retainer member 32 instead of being disposed within an eye such as shown in the form of the invention illustrated in Figs. 2 and 3, rests in the bight G2 and is held from movement with respect to the fastener through the same. The manner of using the device shown in Fig. 5 is identical with that shown in Figs. 1 and 2 and the retainer member 32 functions in identically the same "manner as previously described.

If desired, the construction shown in Fig. 5 maybe formed with a looped portion at the end of the part 4|. In Fig. 6 such construction is shown in which like reference characters are used to designate similar parts. The looped portion formed at the end of the part 4-! in this form of the invention is designated by the reference numeral 43. In this case, the retaining member 32 is threaded through the eye in the looped portion 43 instead of being disposed in the bight 42 as is the case with the form of fastener shown in Fig. 5.

My invention is highly advantageous in that an extremely simple and practical construction is provided by means of which the cover for the container may be either permanently or tem- The cover is easily applied to the container by the cover thereof.

exerting downward pressure upon the same which through the action on the cams on the fastener members cause the same to become spread apart and to clear the hoop. As soon as the container has arrived at its proper closing position, the

abutments or fingers on the fasteners snap into engagement with the shoulder on the hoop thereby holding the cover properlyapplied to the container. Through the action of the retainer memher the fasteners may be permanently held in engagement with the shoulder on the hoop thereby causing the cover to become permanently at tached to the container. If desired, the ends of the retainer member may be secured together through a suitable seal for preventing tampering with the contents of the container. When the cover has been properly applied, the parts of the fastener are disposed within the confines of the container as determined by the flange of My invention can be con struoted at an extremely economical cost and from materials readily bent into the desired form and applied to the cover during the construction thereof. Due to the angular parts of the fasteners the fasteners become securely imbedded in the flange and body structure of the cover, thereby preventing the pulling out of the fastener. Where the parts of the fastener are disposed within the body of the cover and extend completely across the same, said parts serve to stiffen and reinforce the cover and at the same time prevent the pulling out of the fasteners.
