Definitions
- the present invention relates generally to plastic closures, formed from polymeric materials, for use on associated containers, more particularly to a linerless plastic closure including an improved sealing arrangement for sealing cooperation with an associated container.
- Plastic closures formed from polymeric materials have found widespread use on containers, such as for beverages or the like. While some ciosures of this nature may include a separate sealing liner component, many closures of this type can advantageously be formed as linerless" closures, that is, without a separate sealing liner element, in such linerless constructions, one or more features of the ciosure cooperate with an associated container to provide the desired sealing performance for the closure and container package.
- the present invention is directed to an improved linerless ciosure having sealing features which facilitate enhanced sealing performance, while at the same time making efficient use of the polymeric material from which such closures are formed.
- a plastic ciosure for a container comprises a closure body having a top wall portion, and an annular skirt portion depending from the top wall portion.
- the skirt portion can be provided with an internal thread formation for cooperation with the external thread formation of an associated container.
- the present closure includes an outer seal element depending from the top wall portion of the closure body inwardly of the annular skirt portion.
- the outer seal element is generally annular, and defines a generally inwardly facing sealing surface for engagement with a generally outwardly facing sealing surface of the associated container.
- the inwardly facing surface of the outer seal element tapers generally inwardly of the closure body to provide clearance between a base portion of the outer seal element and the container.
- This inwardly tapering configuration which provides the outer seal element with a slanted or undercut configuration, acts to provide clearance from the associated container finish, such that damage due to impact or high pressure does not compromise the sealing integrity of the closure.
- the internal angle/undercut of the inside surface of the outer seal element also acts to pre-load the outer seal, to provide more sealing pressure during all package conditions.
- the closure includes a plurality of circumferentialiy spaced, seal reinforcement elements on the inside surface of the skirt portion of the closure, adjacent the top wall portion.
- the reinforcement elements which are illustrated as shoulder-like projections provided generally at the juncture of the top wall portion and skirt portion, are engageabie by the outer seal element to limit outward deflection of the outer seal element, to thereby enhance sealing cooperation of the outer seal element with the associated container.
- outer seal reinforcement is provided, protruding from the side wall radially outside of the outer seal element, which acts to limit the deflection of the outer seal element during impact and high pressure situations, without adding to the hoop stiffness of the closure.
- the present invention is configured to intentionally increase the ratio or radial stiffness to hoop stiffness, which allows for minimal transfer of strain to the rest of the seal surface under external or internal load, thereby improving sea! efficacy.
- the seal reinforcement elements configured as a discontinuous, deflection- limiting pressure block, act to reinforce the outside seal element in impact situations, as well as in high temperature/high pressure situations, with contact between the outer sea! element and the seal reinforcement elements only occurring in these types of situations, as may be required.
- a key aspect of the present invention is that if facilitates formation of lightweight closures. Due to the fact that a lightweight closure will deflect more under pressure than a relatively heavier one, the present invention has been configured to provide maximum seal pressure after axial stretch of the closure side wall and doming of the top panel have taken place.
- the present closure further includes an inner plug seal element depending from the top wall portion inwardly of the outer seal element.
- the plug seal element is generally cylindrical, and defines an outwardly facing sealing surface for sealing engagement with a generally inwardly facing, inside surface of the associated container.
- the outwardly facing surface of the inner plug seal element has an inwardly tapered free end portion to facilitate application of the closure to a container.
- This configuration of the inner seal element aids in reducing application defects by providing precentering of the closure, with the inner plug seal element also acting in conjunction with the outer seal element to force the container bore into hoop expansion, thereby increasing the sea! pressure on the outside diameter of the container.
- twelve of the seal reinforcement elements are evenly spaced about the circumference of the closure to provide the discontinuous pressure block of the present invention, with the spacing between adjacent reinforcement elements generally corresponding to the circumferential dimension of each reinforcement element.
- Figure 1 is a cross-sectional, diagrammatic view of a linerless closure embodying the principles of the present invention
- Figure 2 is a relatively enlarged, fragmentary view of the circled portion of the closure shown in Figure 1 ; and Figure 3 is a cross-sectional view of the closure shown in Figure 1, showing the interior of a top wall portion of the closure, and the associated sealing features.
- closure 10 configured for cooperative, sealing engagement with an associated container C.
- closure 10 can be formed from suitable polymeric materials, including polypropylene, polyethylene, copolymers, polymer blends, and the like.
- Closure 10 can be efficiently formed by compression-molding or injection-mo!ding techniques.
- closure 10 includes a unitary, one-piece closure body having a top wall portion 12, and an annular skirt portion 14 depending from the top wall portion 12.
- the closure 10 can be provided with a cooperating, internal thread formation 18 (shown in phantom line in Figure 1) on the inside surface of skirt portion 14.
- closure 10 can be configured for tamper-indication to provide readily visually discernible evidence that the closure has been partially or completely removed from the container C.
- closure 10 includes a tamper-indicating pilfer band 20 depending from the lower edge of the annular skirt portion 14,
- the pilfer band 20 can be configured to includes one or more suitable elements on its inside surface for cooperative engagement with an annular blocking ring L of the finish of the container C s whereby the pilfer band 20 is partially or completely separated from the annular skirt portion 14 as the closure 10 is removed from the container.
- closure 10 is a so-called lineriess construction, in that the unitary, one-piece closure body does not include a separate sealing element for sealing cooperation with the associated container C. Rather, the unitary one-piece closure body of closure 10 includes features specifically configured for sealing cooperation with both the inwardly and outwardly facing surfaces of the neck portion or finish of the container C.
- closure 10 includes an outer seal element 24 depending from the top wall portion 12 of the closure body inwardly of the annular skirt portion 14.
- the outer seal element 24 is generally annular, and defines a generaily inwardly facing sealing surface for engagement with a generally outwardly facing sealing surface of the associated container C.
- the inwardly facing surface of the outer seal element 24 tapers generally inwardly of the closure body to provide clearance between a base portion of the outer seal element 24, and the associated container C.
- This inwardly tapering configuration which provides the outer seal element 24 with a slanted or undercut configuration, acts to provide clearance from the associated container finish, such that damage due to impact or high pressure does not compromise the sealing integrity of the closure provided by the outer seal element 24.
- the internal angle/undercut of the inside surface of the outer seal element 24 also acts to pre-load the outer seal element to provide more sealing pressure during all package conditions.
- the closure 10 includes a plurality of circumferentially spaced, seal reinforcing elements 28 on the inside surface of the skirt portion 14 of the closure 10, adjacent the top wall portion 12.
- the reinforcement elements 28, which are illustrated as shoulder-like projections provided generally at the juncture of the top wall portion 12 and the skirt portion 14, are engageable by the outer seal element 24 to limit outward deflection of the outer seal element, to thereby enhance sealing cooperation of the outer seal element 24 with the associated container C.
- outer seal reinforcement is provided, protruding from the side wall radially outside of the outer seal element 24, which reinforcement acts to limit the deflection of the outer seal element during impact and high pressure situations, without adding to the hoop stiffness of the closure.
- the present invention is configured to intentionally increase the ratio of radial stiffness to hoop stiffness, which allows for minimal transfer of strain to the rest of the seal surface under external or internal load, improving seal efficacy.
- a key aspect of the present invention is that this configuration of the seal element and seal reinforcement elements facilitates formation of light weight closures. Due to the fact that a Sight weight closure will deflect more under pressure than a relatively heavier one, the present invention has been configured to provide maximum seal pressure after axial stretch of the closure side wall and doming of the top wall portion have taken place.
- twelve of the seal reinforcement elements 28 are evenly spaced about the circumference of the closure 10 to provide the discontinuous pressure block of the present invention, with the spacing between adjacent ones of the reinforcement elements 28 generally corresponding to the circumferential dimension of each reinforcement element.
- the present closure 10 further includes an inner plug seal element 32 depending from top wall portion 12 inwardly of outer seal element 24.
- the plug seal element 32 is generally cylindrical, and defines an outwardly facing sealing surface for sealing engagement with a generally inwardly facing, inside surface of an associated container C.
- the outwardly facing surface of the inner plug seal element 32 has an inwardly tapered free end portion to facilitate application of the closure 10 to an associated container C.
- the inner plug seal element 32 provides a contoured, lead-in plug, which extends a greater distance from the top wall portion 12 than the outer seal element 24 of the closure.
