t claims. (o1. 229-1) My invention relates `to new and useful improvements in paper containers and more particularly. to a container for milk or other fluids,

the principal object of the invention residing in the provision of a novel form of closure cap in which` means are provided for partially severing a portion thereof to provide a pouring opening having an edge at right angles to the plane of the opening. said partially severed' portion beingv tion with an opening for pouring the'contentsfromt the container.

Fig. is a fragmental side elevation showing the partially torn portion of the cap returned to 5 closing positionY and the flap for holding the saine against accidental displacement; and ,/Fig. 6 is a fragmental sectionalview, with adapted to be positioned for closing the opening bottom closure thereof.

where only a portion of the contents is clischarged, thereby permitting the container with the unused 'contents to be placed in a refrigerator or the like for use at a later time. A

Another object of the invention resides in the provision of e. closurecap having a portion l adapted to be partially torn therefrom on lines on different planes of `*the top portion of the cap whereby when the torn portion is returned'to closingposition parts thereof overlie the edges forming an opening through .the top portion of the cap to prevent leakage therefrom or the en- A trance of impurities into the container.

Another object of the invention consists in the provision lof `novel means. for holding the torn portion of the cap in its reclosing position against accidental displacement. e

Still another object of the invention resides in the rovision of a novel form of bottom closure for the body portion of the container, said` bottom closure including a flange portion spaced from the wall/of the body and in which space adhesive may be applied for securing the bottoma vclosure within the body.

The subject matter of my bottom closure just described is being made the basis of a divisional application.

' with the above and other objects in view,A

which will appear .as the.I description proceeds. my invention consists in the novel details of-construction, and arrangement of parts, described f' in the following specification and illustrated in the accompanying drawing, and while I' have illustrated and described the preferred embodii mentsf the invention, as they'now appear to me, it will be understood that such changes may be made as will fall within the scope of theappended claims.

In the drawing- Fig. .1 is a top pian.'

angles to the plane of the opening. I have further had in mind a closure of a construction permitting resealing or reciosing of the' pouring opening so that where only a part of the contents of the container is used the remaining part may y be' retained in a sanitary condition and the container placed in a refrigerator or similar storagev f space. I have also had in mind the provision ofT a bottom closure of a form cooperating with the 'l taper of the body portion v to provide a spac for the reception of adhesive for securely attaching 3" the bottom closure within the body. With these thoughts in mind I have perfected thepresent container a 'detailed description'of which will follow.`

In the drawing I indicates-the body portion of the container which is of truncated cone shape land this body is formed .from a blank shapedto provide the overlapped edge 2the overlapped edges being secured together by a suitable adhesive. Projecting from the overlappededge 2,

40 adje/eem; the top of the may; is e nap s for a puI pose whichwill be later brought out. At l I have illustrated a bottom closure inserted into theI large end of the body, as shown more particularly in Figs. .2 and 6 of the drawing, and

this bottom closure includes 4a depending flange v 5 bent to project at less l than a 90 angle from the top portion.' Cooperating with the taper of th y AI this ange provides a space between the ou r face of the flange and the inner face of th v body to receive the adhesive which is shown at 6. This adhesive secures the bottom closure securely within the larger' end of the body. It will be understood .-that the .bottom closure is positioned inwardly of the bottom edge lof the body and the bottom edge is then-turned- Ashown in elevation, through the bottom rtionof .the body of the container and the inwardly as shown at 1 to engage the inner Aface of theflange 5.

The top closure of the container is in the form of a cap made from two layers, the outer layer being indicated at 8, while the inner layer is shown at 9., The cap further includes the top portion I and depending flange II, the depending flange I I being adapted to encircle the upper end ofthe body portion I, when the closure is in position, as shown more particularly in Fig. 3 of the drawing and when the cap or closure is applied it reduces the diameter of the upper end of the body as shown at. I2' to provide the offset portion I3 which forms a seat for the bottom edge of the ange Il, as shown more particularly in Figs. 2 and 3 of the drawing. The closure cap may be secured to the body with any suitable form of adhesive. A

The outer layer 8 of the cap closure is weakened or scored across the top I 0 by the lines I4 andI 5, while the inner layer 9 is scored or weakened across the top III by the lines I6. The weakened or scored lines` I4 and I5 originate at a point within the top I0 of the closure and extend to the marginal edge of the ange II as is quite clearly illustrated in Fig. 2 of the drawing. The lines I6 also extend from a point within the top I0 of the closure to the marginal edge of the flange and extending from the marginal edge of the ange, at the point of the weakened or score lines, is a tab I'I. By reference more particularly to Fig. l of the drawing it will be seen that the weakened or score lines I 6 are within the space between the lines I4 and I5 and spaced therefrom for` a purpose which will be later apparent.

In Figs. 1 and 2 of the drawing I have shown the container in its sealed condition with the contents therein. When it is desired to use the contents the user will grasp the tab II and on 'pulling upwardly thereon a portion of the cap will be torn along the lines I4, I5 and I6, as is quiet clearly illustrated in Fig. 4 of the drawing, and it willbe noted that the inner layer 9 of the closure will be torn along the line I6 to provide the opening I8, while the outer layer 8 will be torn along the lines I4 and I5 spaced from the line I6, the outer layer of the torn portion being of greater' width than the inner layer. When the portion is torn from the closure cap the sharp edge I9, of the upper end of the body portion, is exposed and forms a pouring edge at right angles to the plane of the opening. This is .of particular advantage as will be appreciated.

Where only a part of the contents is used then the torn portion will be returned to closing position, shown in Fig. 5 of thedrawing, and the tab I1 will -be engaged beneath theap 3 for holding the torn portion in its closing position.

`When the torn portion is returned to its closing position the outer layer 8, of the cap, will overlie the edges of the opening 'I8 along the lines I6 to prevent any leakage or the entrance of any impurities into the container. While the Weakened or scored lines I6 extend straight through the iiange, as shown quite clearly in Fig. 4 of the drawing, the lines I4 and I5, which extend into and through the flange, are at an angle, the low# er ends of which meet the lines I6. This facilitates the tearing of the portion of the closure along the weakened lines.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:
