- B65D 49/08: Spring-loaded valves
- B65D 2401/15: Tearable part of the closure (B65D2401/60 takes precedence)
- B65D: CONTAINERS FOR STORAGE OR TRANSPORT OF ARTICLES OR MATERIALS, e.g. BAGS, BARRELS, BOTTLES, BOXES, CANS, CARTONS, CRATES, DRUMS, JARS, TANKS, HOPPERS, FORWARDING CONTAINERS; ACCESSORIES, CLOSURES, OR FITTINGS THEREFOR; PACKAGING ELEMENTS; PACKAGES

## Abstract

A closure for a non-refillable bottle is provided wherein the closure is designed to break apart into at least two portions when an attempt is made to pry the closure from the bottle. The breakage is directed across a frangible demarcation that is configured such that breakage of the closure into pieces does not compromise the seal of the closure on the bottle.

## Claims

### Claim 1

A closure for an open neck bottle used as a refill in a dispenser, said closure comprising:
a) a top deck having a periphery and a surface contour together defining an overall shape to the closure;
b) an orifice passing through a relatively central location on said top deck;
c) an outer circumferential skirt extending substantially perpendicular from the periphery of said top deck portion, said outer circumferential skirt comprising at least one functional element configured for engagement with a complementary means inside a dispenser;
d) an inner annular collar extending underneath and perpendicular to said top deck, said collar relatively concentric to said outer circumferential skirt, said inner annular collar surrounding said dispensing orifice and configured with internal sealing means for sealing engagement with complementary features on a neck of a bottle; and
e) a frangible demarcation configured on said closure, separating said closure into at least two portions without intersecting said inner annular collar.

### Claim 2 (depends on 1)

The closure of claim 1, wherein said frangible demarcation is circular in shape and is configured on the top deck of the closure concentric to the inner annular collar, and wherein said circular demarcation has a diameter greater than the diameter of said inner annular collar.

### Claim 3 (depends on 1)

The closure of claim 1, wherein said frangible demarcation is comprised of a plurality of perforations.

### Claim 4 (depends on 2)

The closure of claim 2, wherein said frangible demarcation is comprised of a plurality of circumferentially disposed perforations.

### Claim 5 (depends on 1)

The closure of claim 1, wherein said frangible demarcation is comprised of plastic material that is thinner than the thickness of said skirt of said closure.

### Claim 6 (depends on 1)

The closure of claim 1, wherein said frangible demarcation traverses said closure, bisecting said closure across any axis into two portions.

### Claim 7 (depends on 1)

The closure of claim 1, further comprising a valve reversibly sealing said orifice.

### Claim 8 (depends on 1)

The closure of claim 1, further comprising a plurality of circumferentially disposed ratchet teeth projecting underneath said top deck, said circumferential disposition having a diameter less than the diameter of said inner annular collar and configured for locking engagement with a complementary set of circumferentially disposed ratchet teeth around said open neck of said bottle.

### Claim 9 (depends on 1)

A refill unit for use in dispensing system comprising:
a) the closure of claim 1; and
b) a bottle containing a liquid and having a neck culminating into an open annular end wall, wherein said bottle is sealed on said neck with said closure; and
wherein force, being applied to the closure to remove the closure from the bottle neck, will break the closure across said frangible demarcation into at least two portions without compromise of said seal on said bottle neck.

### Claim 10 (depends on 1)

The closure of claim 1, wherein said surface contour of said top deck is substantially planar and wherein said functional element comprises only the substantially planar top deck of the closure.

### Claim 11 (depends on 10)

The closure of claim 10, further comprising a hinged-lid closure configured for reversible sealing engagement of said dispensing orifice.

### Claim 12 (depends on 1)

The use of the closure of claim 1 in a refill unit comprising the assembly of said closure and a bottle of liquid, said refill unit configured to fit in a dispenser as part of a dispensing system.
