FIELD: process engineering.
SUBSTANCE: invention relates to dispensers of paper reels, paper piles or other materials, and detergents. Proposed dispenser comprises case 20 consisting of first plastic component 17 and second plastic component 18, both being injection-moulded. Said parts are interconnected by seam 21 formed by first and second mating surfaces during injection moulding. Seam cross-section comprises first step nearby outer surface of case 20. Step first contact surface extends in transverse direction at the angle to case outer surface while adjacent second contact surface, an intermediate one, extends across said seam. Second contact surface comprises extending means of contact increase with at least one extra step.
EFFECT: higher seam strength, ruled out dispenser case deformation.
