ABSTRACT:
The disclosure herein describes a device for use in conducting sap collected from maple trees to a sap-processing unit, particularly during sunny days; it comprises a tubular member in which sap is contained and conveyed to the sap-processing unit and a parasol mounted exteriorly of the tubular member for preventing high angled sun rays to be absorbed in the tubular member and to affect the sap flowing during the day but allowing low angled sun rays to be absorbed in part of the tubular member to allow frozen sap to defreeze and flow in the morning. The parasol consists of a semi-cylindrical elongated member mounted over the tubular member and is spaced therefore so as to define an air chamber between the tubular member and the semi-cylindrical member.
