Structure of Automatically Tearing a Hole out of a Slip-in Type Sanitary Cover for Toilet Seats

Abstract

A slip-in type sanitary cover is a plastic bag and includes a cut peripheral edge to define a plastic film that can be torn along the cut peripheral edge to form a hole. Extremely-small-area connecting points are provided on the cut peripheral edge of the plastic film. A larger-area connecting point is located on a front end of the cut peripheral edge of the plastic film. The plastic film is connected to the sanitary cover by the extremely-small-area connecting points and the larger-area connecting point. The plastic film includes at least one hot-melt pressing/bonding point that can hook a front end of the toilet seat when the toilet seat is slipped into the sanitary cover. The extremely-small-area connecting points are pulled and torn off to form the hole when the toilet seat is completely slipped into the sanitary cover. The larger-area connecting point is still connected to the plastic bag after the hole is formed.

1 . A slip-in type sanitary cover for toilet seats, with the slip-in type sanitary cover being a plastic bag and comprising a cut peripheral edge to define a plastic film, with the slip-in type sanitary cover adapted to receive a toilet seat, with the plastic film adapted to be torn along the cut peripheral edge to form a hole allowing passage of feces and/or urine of a user using the toilet seat received in the slip-in type sanitary cover, with a plurality of extremely-small-area connecting points provided on the cut peripheral edge of the plastic film, with the plurality of extremely-small-area connecting points spaced from each other, with a larger-area connecting point located on a front end of the cut peripheral edge of the plastic film, with the plastic film connected to the sanitary cover by the plurality of extremely-small-area connecting points and the larger-area connecting point before forming the hole, with the plastic film including at least one hot-melt pressing/bonding point, with the at least one hot-melt pressing/bonding point adapted to hook a front edge of an outer rim of the toilet seat when the toilet seat is slipped into the slip-in type sanitary cover, with the plurality of extremely-small-area connecting points being pulled and torn off to form the hole when the toilet seat is completely slipped into the slip-in type sanitary cover, and with the larger-area connecting point adapted to be still connected to the plastic bag after the hole is formed.
