4Claims.

This invention relates to improvements in covers or caps for containers.

Container covers or caps as heretofore made have not been entirely satisfactory, some of them, particularly certain caps sometimes termed cover all caps, are of faulty construction especially in the nature of their fastening means. Said means in certain of such caps consists of wire staples pushed through plaits in the caps, which when the material of the caps becomes damp, readily cut through the same and the cap becomes unsealed.

One of the principal objects of the present invention is to provide an improved container cover or cap of sheet material which embodies a portion to cover the containermouth and a skirt portion depending from the first-named portion which skirt portion includes one or more laterally disposed elements of novel function and construc- 'tion, and which together with novel fastening means therefor overcome the above described faults.

Another object of the invention-is to provide a container cover having in addition to the abovementioned lateral element or elements, a downwardly disposed element arranged to overlie the lateral element so that a fastener may be passed both of said elements. Another object is to provide the lateral element in two ply form while the remainder of the skirt portion is single ply.

The means I prefer to employ for accomplishing the foregoing objects, together with other novel and advantageous features of my invention, are illustrated in the drawings accompanying and forming part of this specification and in which- Figure 1 is a front elevation partly in vertical section of one form of my improved container cover applied to the neck of a container such as a beverage bottle.

Fig. 2 is a side elevation of the same at right angles to the position in Fig. 1.

Fig. 3 is a side elevation similar to Fig. 2 but with the container cover only partly applied.

Fig. 4 is a top plan of this form of the invention.

Fig. 5 is a horizontal section of this form taken on the line 5-5 of Fig. 1.

Fig. 613 an enlarged horizontal section of this form taken on the line 6-6 of Fig. 1.

Fig. '1 is a plan of a portion of a strip of blanks for this form in process of making the same.

Fig. 8 is a plan of a portion of said strip ready for application to containers.

Fig. 9 is an end view of the same.

10 a front elevation partly in vertical 55 section of a slightly modified form of my container cover particularly as adapted to containers for diary products.

Fig. 11 is a plan of the same as seen from above, and A Fig. 12 is a horizontal section taken on the line 5 l2--l2 of Fig. 9.

Like characters of reference refer to like parts in all the figures of the drawings.

Referring first to Figs. 7 and 8 of the drawings,

1 have herein illustrated the blank and strip 10 material for the form of the invention shown in Figs. 1 to 6, inclusive. In the drawings, the numeral 2 designates one of the blanks for this form and 3 designates the strip with a series of blanks thereon.

Each blank has a central portion 4 outlined by lines 5, scored or creased in the paper or other material of the strip 3. Any suitable outline may be employed and the octagonal form herein shown is to be understood as illustrative and not limit- 20 ing. The said portions 4'are spaced a suitable distance apart and are ordinarily surrounded by creased or scored portions 8 which eventually become the skirt portions defined in the claims and which will herein be. more fully described. 25

The said skirt portions 6 ordinarily have a plurality of lines I radiating from-the comers of the group of lines 5, but they may be arranged in any other suitable manner. The said lines I later outline folds 8 in the skirt portion 6 of the con- 30 tainer cover.

Preferably there are weakened portions between the sets of scorings or creasings comprising lines 5 and 'l and outlining the container covers to be formed from the blanks 2. In the blanks of 35 Figs. '7 and 8,'the weakened portions are made by placing two perforations 9 and In between adjacent sets of scorings, said perforations being separated by narrow connecting parts ii. The said parts II have scorings l2 across them so that they 40 readily give way when stress is exerted on them by the tearing strip hereinafter to be described.

' There is a series of slits formed substantially parallel to a side edge of the strip 3, -said slits being numbered i3 and it according as they are formed in the. forward or rearward part of a 1 perforation 9. and I3 and Il on the corresponding parts of a perforation ill. The said slits, together with the perforations they are joined to, define side edge portions l5 and Hi. It is clear that the strip 3 can be formed either with one or two of said side edge portions as desired and it will be noted that said edge portions are substantially as long as the blanks.

Preferably the side edge portions I5 and I6 are made of two plies of material while the remainder of the blank 2 is of single ply material. Ordinarily the two plies at the side edges are produced by doubling the edge portions in a blank of the form 5 and dimensions indicated in Fig. 7, into those shown in Fig. 8. The dotted lines II in Fig. 7 indicate the folding lines for producing the two ply structure of Fig. 8.

This form of construction is very advantageous 10 as it is desirable to form the side edge portions of comparatively thick material so that it will not give way when fasteners, hereinafter to be described, are passed through said portions for fastening the covers on the container necks. This form of container cover blank is placed on the container neck as shown in Figs. 1 to 6 inclusive preferably by a machine. The container mouth covering portion 4 is first placed on the mouth M of the container C, in this instance, a beverage bottle, and the blank 21 is then cut off from the strip 3 along one of the lines 20-20 across the strip.

The skirt portion 6 is then pushed downward over the container neck n. The folds or plaits 8 are then formed in the skirt portion 6, the fold- \h1g lines being the creased radiating lines I of the blank 2. It will now be apparent from inspection of Figs. 1, 2, 3 and 6 that the skirt portion 6 has depending portions of two kinds at 0 its .lower part.

One kind of said depending portions, shown particularly in Figs. 2 and 3, includes elements or tabs extending laterally or circumferentially' of the container neck when the cover is placed includes two of such lateral or circumferential tabs, one denoted by l8 extending to the right and the other denoted by 20 extending to the sleft. There is a second kind of depending mem- 'ber orportion indicated by 2|, which consists of short downwardly extending elements or tabs adapted to overlap the lateral elements or tabs l9 and 20. These are shown at the central part of Fig. 1.

The lateral tabs or elements are now wrapped circumferentially around the lower parts of the diagonally disposed portions 22 of the skirt portion 6, holding the folds therein in proper position. It will be noted that the two pairs of lateral tabs I9 and 20 taken together substantially sure round the container neck n, as shown in Fig. 6. Also the end parts of one pair of tabs interlap each with the end part of one of the opposite pair, in other words they are terminally interlapped.

The tabs 2| in this form two in number are then lapped over the parts of the tabs I9 and 20 adjacent to them. Finally, fasteners 23 are pushed through the overlaps and parts thereunder as in Figs. 1 and 6.

Preferably the fasteners employed are staples of suitable form such as 24. The staples 24 consist of two sets of staple elements 25, 26,. 21 and 28, passed through the three tabs and portions 22 of the skirt portion 6, joined by a longitudinal element 29 in juxtaposition to the surface of the outer tab 2| and the inner longitudinal elements 30 and 3|, and the ends 32 and 33 are then bent as in Fig. 6.

One of the ends of the lateral tabs ordinarily contains the pull and is left extending and free as shown in Figs. 1 and 6 so that when it is desired to remove the container cover, it is merely necessary to pull said tab end, indicated by 34, firmly and thus to strip off the lateral tabs l9 and 20, together with the depending tabs 2| which give way along the weakened lines or scorings l2 taking withthem the'fasteners or staples 24. The skirt portion 6 and mouth covering portion 4 is now readily removed.

The modification shown in Figs. 10, 11 and 12 5- is more particularly adapted for use on dairy bottles such as milk and cream bottles. In the form first shown, the parts of the skirt adjoining the sides of the central portion 4 are substantially parallel sided parts. In the present modifi- 10 cation, however, these are shown with converging fore converged as shown in Fig. '10, and are very advantageous in assisting to shape the skirt in under the rounded top portion T of the container CI of that figure.

My improved container covers or capsmay be 20 used alone on the containers or may be used in connection with other sealing devices particularly as illustrated in Figs. 1 and 10. In Fig. 1 my container cover is shown placed over a crown bottle stopper and in Fig. 10 my container cover 25 is shown placed over one of the paper disk stoppers commonly used on milk and cream bottles.

For the purpose of cleamess the paper parts in the sections in the drawings are shown larger in diameter and of greater thickness than actual 30 The method of making the material for the container covers, bottle covers or caps and the like may be performed in any suitable manner for obtaining the desired form of article. Prefer- 35 ably the strip material of the width shown in Fig. '7 is first coated with adhesive along one or both side edge portions and on either one or both sides of the dotted longitudinal line or lines as shown in Fig. 7. The strip is then folded along 40 said dotted linesvor line I! of Fig. '1. This-operationmay be performed either before or after the printing of the labels or other printed matter or otherwise placing of the same on each container cover or cap blank, and it may also be done either 45 before or after the embossing, scoring or perforating on said blanks.

Preferably, however, the printing or placing of the labels or printed matter on the blanks is performed next'after the folding of the longi 50 tudinal plies. Next the scoring or embossing of the folding lines 5 and I, or such other scored lines as may be desired including lines I2, is performed. And finally the perforations O and I0 and the slits l3, l4, l3 and M are formed. 56

'Ordinarily the strip 3 is then formed into a roll suitable for use in a machine for applying the blanks 2'.

It is evident that modifications and changes can be made in my improved article and in the method of making the same which will be within the scope and essence of my invention and I do not therefore limit myself to the exact details of construction herein shown and described. 65
