Abstract
A one piece cover for a container with a hand actuatable tearstrip portion to provide a pour opening and to form a closure for the opening. The cover is adapted to be semi-permanently attached to and thus ordinarily difficult to remove from the container. The tear sections which define the pour opening and the tearstrip portion seal the contents of the container and make it possible to ascertain that the container had not been previously opened, and the closure forms the means for re-closing the container when not in use. In addition, the closure and the cover are provided with a spout for dripless pour flow.

The hand removable tearstrip which defines the pour opening initially is completely sealed in the plastic by very thin connecting integral portions of the plastic. The thin connecting portions are torn by a simple hand ripping action which breaks the seal. This tearing of the seal enables the consumer to ascertain that the container has not been previously opened, assures him of the sanitation of the contents and that the quantity is as stated on the container. Once opened by tearing the tear section, thus breaking the seal, and lifting the tearstrip, a suitable pouring spout is formed which enables the user to pour without dripping and thus reduces waste. If the entire contents of the container are not initially completely used, the tearstrip, now being a closure member, again can be releasably secured in a reclosed position.

Other features of this invention include the fact that the cover is designed to be semi-permanently attached to the container so that it is not ordinarily removable by the consumer. It may be returned with the container to the bottler or vendor who will then remove it and replace it with an unused cover completely sealed as before. The cover embodying this invention is also such that it can be embossed while being processed and can be made of readily available flexible plastic. Probably only limited retooling of existing cover equipment is necessary to adopt and make this invention.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, the cover 10 embodying the present invention is shown engaged to the neck of a conventional milk bottle 12. The bottle 12, shown more clearly in FIG. 4, is provided with a neck opening or dispensing mouth which terminates in a peripheral lip 14, conventionally an enlarged rim or bead on the edge of the bottle.

The cover 10 is seen to comprise a flat, disc-like body portion 16 of some thickness and surrounded by a depending skirt 18 formed integrally with portion 16. The skirt has a lower lip 20 formed inwardly which is adapted to be in tight sealing engagement with the under surface of the bottle opening lip or bead. As clearly shown in FIG. 4, the skirt portion is radially spaced from the portion 16 to define therewith an inverted substantially U-shaped recess 21 which receives the lip 14 of the bottle 12 in sealing engagement. The recess 21 is defined in part by a wall 22 which extends down into the bottle 12 and sealingly hugs the inside surface of the bottle. The resiliency of the plastic material permits the skirt portion 18 with its lip 20 to be pressed over the rim 14 in semi-permanent sealing engagement therewith. This makes it ordinarily quite difficult for the consumer to remove the cover so that the cover will be returned with the bottle where it will be removed and replaced with an unused cover when the bottle is refilled.

The portion 16 is provided with a hand tearout pour opening 24 which is defined generally by tear sections 26 and 28. These tear sections begin at the outer periphery of the disclike portion as at 30 (FIG. 5a) and extend laterally and then inwardly as lines 26a and 28a slightly beyond the bottle rim to form a grip tab. The tear sections then follow the general contour of the rim 14 as tear section portions 26b and 28b to form a semicircular pour opening finally terminating slightly beyond one half the bottle opening at a straight line hinge 34 which provides a hinge for the tearstrip 36 integral with the portion 16. Tearstrip 36, which also forms a closure member for the pour opening, may extend inwardly into the bottle neck as shown, for example, in FIGS. 5 and 7. Tear strip 36 may be slightly thicker and extend upwardly above the upper surface of portion 16 to make a clearly discernible closure member as more clearly shown in FIGS. 1, 2, and 5. The tearstrip 36 also extends outwardly beyond the bottle rim and skirt 18 so as to form a thumb gripping portion or grip tab 38 for the tearstrip. The underside of the tearstrip or closure member 36 is formed with a cavity or recess defined by convex surface 40 which, as shown in FIGS. 3 and 4 opens toward the bottle rim so as to form part of a pouring spout when the closure member 36 is opened. The inner wall 22 is interrupted to provide an opening 42 defined by spaced wall portions 42a and 42b as shown in FIGS. 2, 3 and 4. The portion of the skirt 18 adjacent the grip tab 38, as shown in FIGS. 4, 5, and 5a, is formed with an inclined wall 44 which terminates at the grip tab 38. Thus there is formed a unique pouring spout which is more clearly shown in FIGS. 2 and 4.

To recapitulate when a container with the present invention is handled by a consumer, he can visually inspect the cover and determine that the contents of the bottle are intact by noting that the tearstrip is completely intact at the tear sections. Then, to open the container, he simply grabs the grip tab 38 and pulls upwardly, ripping the tear sections 26 and 28 to the hinge 34 and pours contents from the bottle, such as shown by way of example in FIG. 4.

Turning now to FIG. 8, it is to be noted that in the interest of saving material, the central portion of the closure member 36a can be cored, that is provided with thin walls such as shown at 46 and, similarly, the remainder of the top portion 16 can be cored, or provided with thin walls such as shown at 48, to reduce the amount of material being used in the cover. Otherwise, the function and the operation of the cover designated as 10a is similar to that shown in the previously described figures.

FIG. 9 shows an optional configuration of the skirt portion to which the tab 38 is attached by the tear section. The upper part of the skirt portion has an upper slanted wall 43a inclined downwardly and outwardly as distinguished from the downwardly and inwardly inclination as shown in FIG. 5. This is another means of connecting the tearstrip to the side wall at the initial tear section to form the pouring spout area.

What is claimed is:

l. A resilient plastic cover for a container comprising:

a disc-like body portion,

holding means integral with said body portion for attaching said cover to said container,
