## Abstract

Adhesive compositions that replace gaskets and liners in sealing applications for packages that are detachable with hand force are described. The adhesive compositions are particularly useful in preventing leaks and spillage during storage and transport of its packaged contents. Advantageously, the adhesive composition provides packages with (1) a removal torque of from about 4 to about 20 in-lb and (2) resealable torque on subsequent openings of from about 2 to about 15 in-lb, measured in accordance to ASTM D2063.

## Claims

### Claim 1

An article of manufacture comprising
a first threaded member, and
a second threaded member, matingly engaged with said first threaded member,
wherein the threads of said first threaded member are at least partially coated with a resealable adhesive comprising a waterborne adhesive; and
wherein the resealable adhesive is characterized as having (1) a removal torque of from about 4 to about 20 in-lb, measured in accordance to ASTM D2063, and (2) a resealability torque of from about 2 to about 15 in-lb, measured in accordance to ASTM D2063.

### Claim 2 (depends on 1)

The article of manufacture of claim 1, wherein the waterborne adhesive comprises a pressure sensitive adhesive, ethylene vinyl acetate-based adhesive or polyacrylic-based adhesive.

### Claim 3 (depends on 1)

The article of manufacture of claim 1, wherein the first or the second threaded member is independently made of polypropylene, polyethylene, high density polyethylene, low density polyethylene, polyvinyl chloride or polyethylene terephthalate.

### Claim 4 (depends on 1)

The article of manufacture of claim 1, wherein the first threaded member is a cap, lid or closure.

### Claim 5 (depends on 1)

The article of manufacture of claim 1, wherein the first threaded member is a container neck or bottle neck.

### Claim 6

An article of manufacture comprising a non-threaded closure member having an area of a circumference or perimeter dimension and a height dimension,
wherein the area of the closure member is at least partially coated with a resealable adhesive comprising a waterborne adhesive, further comprising a second non-threaded member matingly engaged with the area of said first non-threaded member, whereupon the resealable adhesive is coated between the first and the second non-threaded members; wherein the resealable adhesive is characterized as having a removal torque of from about 4 to about 20 in-lb, measured in accordance to ASTM D2063; wherein the threaded member has a resealability torque of from about 2 to about 15 in-lb, measured in accordance to ASTM D2063.

### Claim 7 (depends on 6)

The article of manufacture of claim 6, wherein the waterborne adhesive comprises a pressure sensitive adhesive, ethylene vinyl acetate-based adhesive or polyacrylic-based adhesive.

### Claim 8 (depends on 6)

The article of manufacture of claim 6, wherein the first or the second non-threaded member is independently made of polypropylene, polyethylene, high density polyethylene, low density polyethylene, polyvinyl chloride or polyethylene terephthalate.

### Claim 9 (depends on 6)

The article of manufacture of claim 6, wherein the first non-threaded member is a cap, lid or closure.

### Claim 10 (depends on 6)

The article of manufacture of claim 6, wherein the first non-threaded member is a container neck or bottle neck.

### Claim 11

A method of sealing members comprising:
(a) providing a first member;
(b) providing a second member capable of matingly engaging with said first member; at least one of the said first and second members being at least partially coated with a resealable coating composition;
(c) matingly engaging said first and second members;
whereupon the reseable coating composition substantially fills the matingly engaging space between the first and the second members;
wherein the resealable coating composition is a waterborne adhesive characterized as having a removal torque of from about 4 to about 20 in-lb, measured in accordance to ASTM D2063;
wherein the resealable adhesive has a resealability torque of from about 2 to about 15 in-lb, measured in accordance to ASTM D2063.

### Claim 12 (depends on 11)

The method of sealing members of claim 11, wherein the first or the second member is independently made of polypropylene, polyethylene, high density polyethylene, low density polyethylene, polyvinyl chloride or polyethylene terephthalate.

### Claim 13 (depends on 11)

The method of sealing members of claim 11, wherein at least one of the said first and second members is a cap, lid or closure.

### Claim 14 (depends on 11)

The method of sealing members of claim 11, wherein the first and the second members are threaded members.

### Claim 15 (depends on 11)

The method of sealing members of claim 11, where in the first and the second members are non-threaded members.
