Abstract
Abstract A device for sealing an opening in the end wall of a container having at least one end wall and a side wall wherein a first upwardly, from the end wall, and outwardly and downwardly extending rim is peripherally formed at the juncture of the end wall and side wall of the container. The device has a first plate having a pad of resilient material attached to one surface of the plate and adapted to sealingly cover the opening in the end wall of the container. A second plate is attached to the first plate so as to be at substantially right angles thereto in sealing position with the pad on the first plate being on the inside of the angle. The second plate is adapted to extend downwardly on the outside of the side wall of the container in close proximity thereto when the device is in sealing position. A tongue extends from adjacent the free end of the second plate toward the attachment of the plates to one another. The tip of the tongue is spaced from the attachment of the plates to one another sufficiently and biased so as to slide under and bear against the lower surface of the rim of the container when the device is in sealing position. In this manner the pad of resilient material is caused to sealingly close the opening in the end wall of the container. Means are provided for moving the tip of the tongue from beneath the rim of the container to release the device therefrom.

A device for sealing an opening in the end wall of a container having at least one end wall and a sidewall wherein a first upwardly, from the end wall, and then outwardly and downwardly extending rim is peripherally formed at the juncture of the end wall and side wall of the container, which device comprises: a. a first plate; b. a pad of resilient material attached to one surface of the plate and adapted to sealingly close the opening in the end wall of container; c. a second plate attached to the first plate so as to be at substantially right angles thereto in sealing position with the pad on the first plate being on the inside of the angle, the second plate being adapted to extend downwardly along the outside of the sidewall of the container in close proximity thereto when the device is in sealing position; d. a tongue extending from adjacent the free end of the second plate toward the attachment of the plates to one another, the tip of the tongue being spaced therefrom sufficiently and biased so as to slide along an extension of a diameter of the container under and bear against the lower surface of the rim of the container in sealing position, whereby the pad of resilient material is caused to sealingly close the opening in the end wall of the container; and e. means for moving the tip of the tongue from beneath the rim of the container to release the device therefrom; and f. a ridge adapted to extend downwardly along the end wall side of the rim of the container in close proximity thereto so as to co-act with the tongue in securely positioning the pad in sealing position, the ridge being in at least two sections, at least one on each side of the tongue.
Claim 2
Independent Claim
308 words
A device for sealing an opening in the end wall of a container having at least one end wall and a sidewall wherein a first upwardly, from the end wall, and then outwardly and downwardly extending rim is peripherally formed at the juncture of the end wall and side wall of the container, which device comprises: a. a first plate; b. a pad of resilient material attached to one surface of the plate and adapted to sealingly close the opening in the end wall of container; c. a second plate attached to the first plate so as to be at substantially right angles thereto in sealing position with the pad on the first plate being on the inside of the angle, the second plate being adapted to extend downwardly along the outside of the sidewall of the container in close proximity thereto when the device is in sealing position; d. a tongue extending from adjacent the free end of the second plate toward the attachment of the plates to one another, the tip of the tongue being spaced therefrom sufficiently and biased so as to slide along an extension of a diameter of the container under and bear against the lower surface of the rim of the container in sealing position, whereby the pad of resilient material is caused to sealingly close the opening in the end wall of the container; and e. means for moving the tip of the tongue from beneath the rim of the container to release the device therefrom; and f. a ridge adapted to extend downwardly along the end wall side of the rim of the container in close proximity thereto so as to co-act with the tongue in securely positioning the pad in sealing position, the ridge being in at least two sections, at least one on each side of the tongue.
Claim 3
Dependent Claim
14 words
The device of claim 1 wherein the ridge is attached to the first plate.
Claim 4
Dependent Claim
17 words
The device of claim 1 wherein the ridge is attached by a shoulder to the second plate.
Claim 5
Dependent Claim
119 words
The device of claim 1 wherein the two plates are pivotally connected together, and including a tab on the tongue which extends upwardly from the outside surface thereof along the outside of the rim and wherein the means for moving the tip of the tongue comprises a beam extending from the first plate toward the tab and adapted to bear at its free end against the tab so as to hold the first plate immobile when the device is in sealing position and adapted to push against the tab when the first plate is depressed from sealing position, whereby the free end of the tongue is moved from beneath the rim of the container to release the device therefrom.
Claim 6
Dependent Claim
54 words
The device of claim 1 wherein the first plate is adapted to extend all the way across the end wall of the container and includes a hook at the free end thereof so as to hook under the lower surface of the rim on the outside thereof when the device is in sealing position.
Claim 7
Dependent Claim
23 words
The device of claim 1 including a frame attached to the first plate to assist in holding the pad in proper position thereon.
Claim 8
Dependent Claim
22 words
The device of claim 1 wherein the means for moving the free end of the tongue comprises a handle on the tongue.
Claim 9
Dependent Claim
64 words
The device of claim 1 wherein the tongue is pivotally connected to the second plate and extends for at least part of its length along the surface of the plate on the inside of the angle whereby the proximity of the second plate to the sidewall of the container in sealing position will bias the tongue into position beneath the rim of the container.
