Abstract
Abstract A water applicator includes a closed water main reservoir connected to a holding member for supporting the core of a tape roll. An auxiliary water reservoir is disposed in an upper portion of the main water reservoir with a water absorbing member positioned in the auxiliary water reservoir to contact the tape as it is withdrawn from the holding member. A scraper is disposed on the holding member in front of the absorbing member to remove excess water from the tape to prevent the tape from dripping. The applicator is convenient to carry and free of dripping even when turned upside down.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
192 words
A water applicator for wetting adhesive tape including a tape support member for rotatably supporting a roll of the tape, a water absorbing member disposed to the front of the tape support member, and a cutting blade disposed adjacent the water absorbing member so that the tape is withdrawn in sliding contact with the top of the water absorbing member to apply water to the adhesive layer on the rear side of the tape, comprising: a. an enclosed main water reservoir connected to the tape support member, b. an auxiliary water reservoir disposed in an upper portion of the main water reservoir and communicating with the main water reservoir, c. the water absorbing member having a lower portion inserted into the auxiliary water reservoir through an opening in the top wall of the auxiliary water reservoir and an upper portion extending into a path for the tape, d. a cover having a front end pivotably mounted on the front of the auxiliary water reservoir in front of the water absorbing member, and e. the cutting blade projecting from the front end of the holding cover in front of the water absorbing member.
Claim 2
Dependent Claim
192 words
A water applicator for wetting adhesive tape including a tape support member for rotatably supporting a roll of the tape, a water absorbing member disposed to the front of the tape support member, and a cutting blade disposed adjacent the water absorbing member so that the tape is withdrawn in sliding contact with the top of the water absorbing member to apply water to the adhesive layer on the rear side of the tape, comprising: a. an enclosed main water reservoir connected to the tape support member, b. an auxiliary water reservoir disposed in an upper portion of the main water reservoir and communicating with the main water reservoir, c. the water absorbing member having a lower portion inserted into the auxiliary water reservoir through an opening in the top wall of the auxiliary water reservoir and an upper portion extending into a path for the tape, d. a cover having a front end pivotably mounted on the front of the auxiliary water reservoir in front of the water absorbing member, and e. the cutting blade projecting from the front end of the holding cover in front of the water absorbing member.
Claim 3
Dependent Claim
19 words
