## Abstract

A lubricant pack for a paper shredder is presented, which includes two covering layers disposed side-by-side and edges thereof are thermally welded to form a sealed bag. Lubricant is enclosed in the bag, and at least one inner seal is configured in the bag. Surrounded by the inner seal is a hollow region not containing the lubricant. When the paper shredder cuts the lubricant pack, air contained in the lubricant tends to be released from the hollow region. Another lubricant pack for a paper shredder is presented, which includes two covering layers disposed side-by-side and edges thereof are thermally welded to form a sealed bag. Lubricant is enclosed in the bag, and at least one an inner seal is configured in the bag. Surrounded by the inner seal is a solid region not containing the lubricant, and multiple hollow impressions are formed in the solid region. When the paper shredder cuts the lubricant pack, air contained in the lubricant tends to be released from the hollow impressions of the solid region.

## Claims

### Claim 1

A lubricant pack for a paper shredder comprising:
two covering layers disposed side-by-side;
wherein edges of the two covering layers are thermally welded to form a sealed bag;
the lubricant is enclosed in the bag;
at least one inner seal is configured in the bag; and
surrounded by the inner seal is a hollow region not containing the lubricant.

### Claim 2 (depends on 1)

The lubricant pack as claimed in claim 1, wherein the hollow region is in a geometrical shape.

### Claim 3 (depends on 1)

The lubricant pack as claimed in claim 1, wherein a width for sealing the hollow region is smaller than that for sealing the bag.

### Claim 4 (depends on 1)

The lubricant pack as claimed in claim 1, wherein a width for sealing the hollow region is equal to that for sealing the bag.

### Claim 5 (depends on 1)

The lubricant pack as claimed in claim 1, wherein the hollow region is sealed to separate to at least two small hollow regions.

### Claim 6

A lubricant pack for a paper shredder comprising:
two covering layers disposed side-by-side;
wherein edges of the two covering layers are thermally welded to form a sealed bag;
the lubricant is enclosed in the bag;
at least one inner seal is configured in the bag;
surrounded by the inner seal is a solid region not containing the lubricant; and
hollow impressions are formed in the solid region.

### Claim 7 (depends on 6)

The lubricant pack as claimed in claim 6, wherein each hollow impression is in a geometrical shape.
