Fastener for securing the closure of a container

Claim 2

A fastener for securing a closure to a container, in which the closure has a first ring means and the container has a second ring means, such that when the closure and the container are fully engaged, the first and second ring means are coaxially aligned, thereby providing a bore through both the first and second ring means, the fastener comprising: (a) a body having a longitudinal axis; (b) the body having first projection means dimensioned such that the body can be inserted through the bore in a first direction along its longitudinal axis but is prevented from moving in a second direction, being 180° to the first direction, by abutting the surface surrounding the bore; (c) the body having second projection means located at a distance in the second direction from the first projection means, that prevents the body from moving in the first direction by abutting the surface surrounding the bore; (d) at least one of the projection means is capable of being detached from the fastener by tearing away from the body during removal of the fastener from the container by movement in either the first or second direction.

Claim 3

The fastener in Claim 1 wherein one of the projection means is attached to the fastener by a relatively thin web which is capable of being torn during the removal of the fastener from the container.

Claim 4

The fastener in Claim 1 wherein the projection means is attached to the body by means of a relatively thin web which is torn and thereby detached during the removal of the fastener from the container in the second direction.

Claim 5

The fastener in Claim 3 wherein the first projection means comprises several locking tangs.

Claim 6

The fastener in Claim 3 or 4 wherein second projection means comprises a single flange.

Claim 7

The fastener in Claims 1 to 5 wherein the detached projection means cannot be reattached to the fastener, thereby indicating that the container has been tampered with.

Claim 8

The fastener in Claims 1 to 6 wherein a force greater than about 5 lbs. is required to remove the fastener from the ring means.

Claim 9

The fastener in Claims 1 to 7 wherein the body comprises a core section surrounded by an outer section to which is attached the first projection means such that during removal of the fastener in a second direction, the outer section is held fast against the surface surrounding the bore by means of the first projection means and the core moves relative to the outer section.

Claim 10

The fastener in Claim 8 wherein the outer section is attached to the core by a relatively thin web which is capable of being torn during the removal of the fastener from the container.

Claim 11

The fastener in Claim 9 wherein the outer section comprises two wings to which the first projection means are attached.

Claim 12

The fastener in Claim 8 wherein the core section has a first end, into which a groove is moulded and the outer section comprises: (a) a base plate attached to the second end of the core section by means of a first hinge; (b) at least two wings, each attached to the base plate by means of a second hinge of relatively thin web which is capable of being torn during removal of the fastener for the purpose of opening the container; (c) lug means moulded to each wing, adapted to engage the groove moulded into the core section; such that, the base plate can be folded about the first hinge so that the base plate contacts the core section and the wings can be folded about the second hinges so that they contact the core section and the lug means engage the groove moulded into the core section.

Claim 13

Claim 12. The fastener in Claim 11 wherein the core section and the wings extend to the second projection means, the upper body thereby being moulded in a collapsed form integral with the lower body.

Claim 14

The fastener in Claim 11 or 12 further comprising a handle means for pulling the fastener from the aligned rings.

Claim 15

The fastener in Claim 13 wherein the handle means is embellished with a label or emblem.

Claim 16

A fastener for securing a closure to a container, in which the closure has a first ring means and the container has a second ring means, such that when the closure and the container are fully engaged, the first and second ring means are coaxilly aligned, thereby producing the bore through both first and second means, comprising: (a) a lower body wherein the lower body includes a core section having a first end into which is moulded a groove; a base plate attached to the second end of the core section by means of a first hinge; two wing elements, each attached to the base plate by means of a second hinge of relatively thin web which is capable of being torn during removal of the fastener for the purpose of opening the container, and cannot be reattached to the fastener; lug means moulded to each wing, adapted to engage the groove moulded into the core section; the lower body, base plate, wing elements and lug means dimensioned such that they can be inserted through the bore in a first direction, but be prevented from moving in a second direction, being 180° to the first direction, by abutting the surface surrounding the bore; (b) an upper body having a second projection means, located at a distance in the second direction from the first projection means, preventing the upper body from moving in the first direction by abutting the surface surrounding the bore; (c) a handle means for pulling the fastener from the aligned ring.

Claim 17

A fastener for securing a closure to a container, in which the closure has a first ring means and the container has a second ring means, such that when the closure and the container are fully engaged, the first and second ring means are coaxilly aligned, thereby producing the bore through both first and second means, comprising: (a) a lower body wherein the lower body includes a core section having a first end into which is moulded a groove; a base plate attached to the second end of the core section by means of a first hinge; two wing elements, each attached to the base plate by means of a second hinge of relatively thin web which is capable of being torn during removal of the fastener for the purpose of opening the container, and cannot be reattached to the fastener; lug means moulded to each wing, adapted to engage the groove moulded into the core section; the lower body, base plate, wing elements and lug means dimensioned such that they can be inserted through the bore in a first direction, but be prevented from moving in a second direction, being 180° to the first direction, by abutting the surface surrounding the bore; (b) an upper body having a second projection means, located at a distance in the second direction from the first projection means, preventing the upper body from moving in the first direction by abutting the surface surrounding the bore; (c) a handle means for pulling the fastener from the aligned ring.

Claim 18

The fastener in Claim 15 wherein the fastener is manufactured in polyethylene.

Claim 19

A method of manufacturing the fastener of Claim 11, comprising: (a) moulding a core section having a first end, in which a groove is moulded; a base plate which is attached to the second end of the core section by means of a first hinge; two wings, each attached to the base plate by means of the second hinge of relatively thin web which is capable of being torn during removal of the fastener for the purpose of opening the container; lug means on the end of each wing, adapted to engage the groove moulded into the core section; (b) folding the base plate about the first end so that the base plate contacts the core section; (c) folding the wings about the second hinges so that they contacts the core section; (h) engaging the lug means into the groove moulded into the core section.
