  • Publication number: 20240041168
    Abstract: A zipper strap structure according to an embodiment includes a first strap, a second strap disposed side by side with the first strap, an internal coupling unit, and an external coupling unit. According to the invention, the internal and external coupling of the zipper strap structure is performed with very high accuracy and precision. In addition, when the zipper strap structure is operated, a user can intuitively recognize whether the zipper strap structure is opened or closed by senses of touch and hearing. Since a user can effectively seal contents by the internal and external coupling of the zipper strap structure and can clearly recognize an operation state of the zipper by senses of touch and hearing, the user does not have to perform repeated checking of whether or not a zipper is completely closed, unlike the related art.

  • Patent number: 9657698
    Abstract: Disclosed herein is a vehicle fuel pump module. The vehicle fuel pump module is configured such that a controller is spaced apart from a plate body installed so as to be exposed out of a fuel tank by a support member and an air gap is provided between the plate body and the controller. Consequently, a gas generated from a fuel in the fuel tank is discharged to the atmosphere by an outdoor air circulating the air gap and thus it may be possible to prevent the gas from affecting electronic parts of the controller.
