AI Technical Summary
Technical Problem
The base of traditional snap fasteners is too thick, resulting in insufficient fabric fit, which affects the product's appearance and user experience.
Method used
By installing a first mounting post on the slingshot cup and setting a second cavity in the first buckle surface to form a first flange, the thickness of the slingshot cup is reduced. At the same time, a protective gasket and an elastic washer are set in the slingshot cup to improve the connection tightness and aesthetics.
Benefits of technology
This effectively avoids the problem of excessively thick bottom parts, while maintaining the product's fastening force and aesthetics, and improving the fit of the fabric and the overall appearance.

Abstract
An ultrathin snap fastener, comprising a female snap assembly, wherein a first snap surface of the female snap assembly has a first cavity and a first opening, a first conical gasket and a first snap surface gasket are provided in the first cavity, the first snap surface gasket encases the first conical gasket and forms a second cavity, the first snap surface gasket is provided with a second opening, and a conical surface of the first conical gasket faces the second opening. An upper surface of a spring cup is provided with a first assembly column, and a lower surface of the spring cup is provided with a third opening. During assembly, the first snap surface and the spring cup are located on two sides of a first fabric respectively, the first assembly column penetrates the first fabric and is in press-fit with the first conical gasket, so that the first assembly column forms a flange in the second cavity, and the flange is engaged with the first snap surface gasket, so as to fix the first snap surface and the spring cup to the first fabric. In this solution, the first assembly column is mounted on the spring cup, and the second cavity configured to form the flange of the first assembly column is formed in the first snap surface, so that the thickness of the spring cup is reduced, thereby avoiding an excessive thickness of a base member.
