A lug closure includes a central top panel, an annular channel outboard of the top panel, a downwardly extending skirt outboard of the channel, the skirt terminating at an inward curl that defines a curl height, and lugs formed in the curl. Each one of the lugs includes a body that extends radially inwardly from the skirt. The body includes a leading edge that merges into a leading portion of the curl. The leading edge tapers in thickness from the curl height to a minimum lug thickness and forms a leading edge vertical taper angle from horizontal between 6 and 15 degrees. A trailing edge merges into a trailing portion of the curl and the trailing edge tapers in thickness from the curl height to the minimum lug thickness.

Lug closure

A lug closure () includes a central top panel (), an annular channel () outboard of the top panel, a downwardly extending skirt () outboard of the channel, the skirt terminating at an inward curl () that defines a curl height, and lugs () formed in the curl. Each one of the lugs includes a body that extends radially inwardly from the skirt. The body includes a leading edge () that merges into a leading portion () of the curl. The leading edge tapers in thickness from the curl height to a minimum lug thickness and forms a leading edge vertical taper angle from horizontal between 6 and 15 degrees. A trailing edge () merges into a trailing portion () of the curl and the trailing edge () tapers in thickness from the curl height to the minimum lug thickness.

A tobacco container having a plastic insert body and a method of attaching the insert body are disclosed. Some embodiments disclose an insert body that is configured to accommodate dimensional variations in the tobacco container. Some embodiments disclose an insert body that is configured to decrease weight in the tobacco container.

Tobacco container with plastic insert

The present invention relates to closures for mating with containers having a threaded finish. The closures comprise a flange and a skirt downwardly depending therefrom. The skirt includes a deformable element formed of a different material than that of the flange and skirt and disposed on an interior surface. The deformable element inner diameter is smaller than the outer diameter of the container, and accordingly deforms upon mating the closure with the container. The container threads impress threads into the deformable element to form threads on the closure. The deformable element is formed of a suitable material. The closures of the present invention provide for the use of high-speed press-on capping equipment.

Closure having band with internal thread formed by impression

A press-on, twist-off container assembly of the type that is used, for example, and baby food containers includes a container that has, as conventional, a finish portion with at least one external thread and a closure that is mounted on the container. The closure is of the press-on, twist-off type and includes a panel portion and a skirt portion that together define a generally cylindrical interior recess. As is conventional, a deformable gasket is mounted within the interior recess that has a thread engaging portion that is deformed so as to at least partially conform to the external threads of said finish portion of said container. The thread engaging portion advantageously has a plurality of inwardly extending raised flutes that are circumferentially spaced irregularly about the thread engaging portion. At least some of the flutes are in contact with at least one of the external threads at respective points of contact, and each external thread has a total distance spanned by such points of contact. As a result of the irregular spacing of the flutes, the container assembly will have an aggregate distance spanned that is a sum of the total distance spanned for all of the external threads that is less than it would be were the flutes spaced regularly. Accordingly, the amount of torque that is necessary to remove the closure is comparatively reduced.

A composite closure includes a band and an insert disk. A contact surface urges downwardly against the disk even while the band moves longitudinally relative to the disk or container. The closure has a fully tightened position in which the band's ring contacts the disk's annular channel, a loose position in which the ring is spaced apart from the annular channel, and an intermediate tightened position in which the ring is spaced apart from the disk and the contact surface urges against the curl. Another composite closure includes plural fins or gussets. The fins or gussets engage the peripheral curl of the insert disk to secure the band to the disk, which provides a resistance to initial unscrewing of the band. The disengagement torque required to disengage the curl from the fins may enable the closure to function as a one-piece closure.

Composite closure having an insert with a peripheral curl

A closure for mating with a container has a threaded finish. The closure comprises a flange and a skirt downwardly depending therefrom. The skirt includes a deformable element formed of a different material than that of the flange and skirt and disposed on an interior surface. The deformable element inner diameter is smaller than the outer diameter of the container, and accordingly deforms upon mating the closure with the container. The container threads impress threads into the deformable element to form threads on the closure. The deformable element is formed of a suitable material. The closure of the present invention provides for the use of high-speed press-on capping equipment.

A composite closure type container assembly that is designed for use with unthreaded containers includes a container having an unthreaded outer surface and an opening that is defined by an upper rim, a sealing disc that is sized and shaped to cover the opening and to seal against the upper rim and a securement member that is removably anchored to the container for securing the sealing disc on the container. In one embodiment, the securement member is removably anchored to the container by using a tight frictional engagement. In a second embodiment, the anchoring is accomplished by shaping the container so as to have a downwardly depending skirt that engages and retains the securement member in position until the container assembly is opened.

A press-on, twist-off container assembly of the type that is used, for example, and baby food containers includes a container that has, as conventional, a finish portion with at least one external threadand a closure that is mounted on the container. The closure is of the press-on, twist-off type and includes a panel portion and a skirt portion that together define a generally cylindrical interior recess. As is conventional, a deformable gasket is mounted within the interior recess that has a thread engaging portion that is deformed so as to at least partially conform to the external threads of said finish portion of said container. The thread engaging portion advantageously has a plurality of inwardly extending raised flutes that are circumferentially spaced irregularly about the thread engaging portion. At least some of the flutes are in contact with at least one of the external threads at respective points of contact, and each external thread has a total distance spanned by such points of contact. As a result of the irregular spacing of the flutes, the container assembly will have an aggregate distance spanned that is a sum of the total distance spanned for all of the external threads that is less than it would be were the flutes spaced regularly. Accordingly, the amount of torque that is necessary to remove the closure is comparatively reduced.

A composite closure includes a band and an insert disk. A contact surface urges downwardly against the disk even while the band moves longitudinally relative to the disk or container. The closure has a fully tightened position in which the band's ring contacts the disk's annular channel, a loose position in which the ring is spaced apart from the annular channel, and an intermediate tightened position in which the ring is spaced apart from the disk and in which the contact surface urges against the curl. A retaining feature, which presses upwardly against the disk during the opening process, defines a gap in which the disk curl is disposed.
