Abstract
Abstract The invention provides a novel integrated body of an elongated form capable of sustainedly releasing vapor of a vaporizable substance contained in the body into the atmosphere, such as an aromatic compound, pesticide, fungicide and a sex pheromone as a means for the control of a pest. The inventive sustainedly vapor-releasing integrated body is very advantageous in the high efficiency of shaping into desired configuration and setting or installation in the field in large numbers by virtue of the good shape-retainability as a result of the integrated structure composed of a capillary tubing of a polymeric material filled with the vaporizable substance and a metal wire with plastic deformability and a sufficiently large cross section and integrated side-by-side with the capillary tubing to retain the latter in the compulsorily deformed disposition. The inventive integrated bodies are suitable for mass production in a relatively simple process.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
85 words
A sustainedly vapor-releasing integrated body having excellent shape-retainability which comprises (a) a capillary tubing sealed at both ends and having flexibility made of a polymeric material, (b) a metal wire having plastic deformability to retain a deformed configuration and integrated with the capillary tubing in a side-by-side manner along the longitudinal direction thereof, and (c) a vaporizable substance filling the pore of the capillary tubing, which is capable of vaporizing through the walls of the capillary tubing and exhibiting an activity in the vapor phase.
Claim 2
Dependent Claim
85 words
A sustainedly vapor-releasing integrated body having excellent shape-retainability which comprises (a) a capillary tubing sealed at both ends and having flexibility made of a polymeric material, (b) a metal wire having plastic deformability to retain a deformed configuration and integrated with the capillary tubing in a side-by-side manner along the longitudinal direction thereof, and (c) a vaporizable substance filling the pore of the capillary tubing, which is capable of vaporizing through the walls of the capillary tubing and exhibiting an activity in the vapor phase.
Claim 3
Dependent Claim
23 words
The sustainedly vapor-releasing integrated body as claimed in claim 1 wherein the metal wire has a covering layer made of a polymeric material.
Claim 4
Dependent Claim
36 words
The sustainedly vapor-releasing integrated body as claimed in claim 2 wherein the covering layer on the metal wire is made of the same polymeric material as the polymeric material of which the capillary tubing is made.
Claim 5
Dependent Claim
26 words
The sustainedly vapor-releasing integrated body as claimed in claim 1 wherein the metal wire is integrated with the capillary tubing by bonding with an adhesive agent.
Claim 6
Dependent Claim
34 words
The sustainedly vapor-releasing integrated body as claimed in claim 1 or claim 2 wherein the metal wire with or without a covering layer is integrated with the capillary tubing by melting the polymeric material.
Claim 7
Dependent Claim
22 words
The sustainedly vapor-releasing integrated body as claimed in claim 1 wherein the metal wire and the capillary tubing are integrated by intertwisting.
Claim 8
Dependent Claim
37 words
The sustainedly vapor-releasing integrated body as claimed in claim 1 wherein the metal wire integrated with the capillary tubing has a length substantially equal to the length of the capillary tubing with the end surfaces being flush.
Claim 9
Dependent Claim
52 words
The sustainedly vapor-releasing integrated body as claimed in claim 1 wherein the metal wire has a sufficiently large cross section such that the integrated body, when deformed by the application of an outer force, can retain the deformed configuration when the outer force is released resisting the resilience of the capillary tubing.
Claim 10
Dependent Claim
29 words
The sustainedly vapor-releasing integrated body as claimed in claim 1 wherein the metal wire is made of a metal selected from the group consisting of aluminum, copper and iron.
Claim 11
Independent Claim
184 words
A method for the preparation of a sustainedly vapor-releasing integrated body comprising (a) a capillary tubing having flexibility made of a polymeric material sealed at least at one end thereof, (b) a metal wire having plastic deformability to retain a deformed configuration and integrated with the capillary tubing in a side-by-side manner along the longitudinal direction thereof, and (c) a vaporizable substance filling the pore of the capillary tubing, which is capable of vaporizing through the walls of the capillary tubing and exhibiting an activity in the vapor phase, which comprises the steps of (i) integrating side-by-side a capillary tubing and the metal wire each in a continuous length to form a continuous-length integrated body, (ii) filling the pore of the capillary tubing with the vaporizable substance, (iii) heat-sealing the capillary tubing filled with the vaporizable substance at portions with intervals to partition the pore of the capillary tubing into sections and (iv) cutting the integrated body into unit-length bodies at positions within the sealed portions or at positions closely adjacent to the sealed portions always at the same side of the sealed portion.
Claim 12
Independent Claim
184 words
