Sealing structure capable of withstanding water pressure
A sealing structure capable of withstanding water pressure, which has a zipper on two sides of a flexible member at an opening of a container, one margin of the opening is a vertical extension of a buffer plate. Fitted to one end of the buffer plate is a pillar-shaped inside fastener unit. Another margin of the opening is a vertical extension of a buffer plate, fitted to one end of the buffer plate is a C-shaped outside fastener unit. By closing the opening with the zipper, wrapping of the inside fastener unit by the outside fastener unit, and an additional C-shaped exterior wrapping strip wrapping the outside fastener unit, so the inside and outside fastener units are completely and firmly combined to completely seal the opening of a flexible container, and water is kept from seeping in, thereby achieving its sealing purposes to resist water and withstand water pressure.
(a) Field of the Invention
The present invention relates to a sealing structure capable of withstanding water pressure, having a zipper at an opening of a closable container, a pillar-shaped inside fastener unit and a C-shaped outside fastener unit extending vertically from two margins of the opening, to resist water from seeping after the inside fastener unit and the outside fastener unit are firmly combined.
(b) Description of the Prior Art
At an opening of a conventional container 1 having a zipper closing (shown in
Therefore, to improve on the above shortcomings of inability to prevent water from seeping as in the prior art of opening sealing structure, the present invention has included a zipper inside the opening, and has vertical extensions of a pillar-shaped inside fastener unit and a C-shaped outside fastener unit on two margins of the opening, and after the zipper has rapidly closed the opening, the inside fastener unit is wrapped by the outside fastener unit, so the inside and outside fastener units are closely combined together, so even when outside water has immersed the opening or the water has a larger pressure, the outside fastener unit is subjected to water pressure, and the outside fastener unit envelops and combines firmly on the inside fastener unit, to completely obstruct water seepage and achieve the purpose of prevention against water seepage.
Moreover, the vertical extension on the inside and outside fastener units is a buffer plate structure, providing buffer performance in case the sealing is subjected to outside forces.
Secondly, to enhance water-resistant effects, there is optionally a C-shaped exterior wrapping strip, wrapping onto the outside fastener unit, so the sealing is protected by double sealing mechanisms.
BRIEF DESCRIPTION OF THE DRAWINGS
As shown in
When the zipper 4 has sealed the opening, with an opening of the outside fastener unit 32 slightly turned outward, the inside fastener unit 31 is wrapped inside the outside fastener unit 32; in other words, the outside fastener unit 32 tightly wraps the inside fastener unit 31. Likewise, the opening of the exterior wrapping strip 5 is slightly turned out, so the outside fastener unit 32 is easily accommodated inside the exterior wrapping strip 5. By interlocking the wrapping effects of the inside fastener unit 31, the outside fastener unit 32 and the exterior wrapping strip 5 on the sealing of the opening, water could not seep in. Even when water level is higher than the sealing, water pressure is applied directly on the exterior wrapping strip 5, tightening the inside fastener unit 31, the outside fastener unit 32 and the exterior wrapping strip 5, thereby enhancing its water-resistant efficiency. When the sealing is subjected to an outside force, the buffer plate 33 provides a buffer for the pulling force.
Claims
1. A sealing structure capable of withstanding water pressure, having a zipper on two insides of an opening of a flexible unit of a container, wherein: one margin of the opening being a buffer plate, fitted to a margin of he buffer plate being a pillar-shaped inside fastener unit, fitted to another margin of the buffer plate being another vertically extended buffer plate, fitted to an end of the buffer plate being a C-shaped flexible outside fastener unit, thereby after the zipper has closed the opening and an opening of the outside fastener unit is turned outward, permitting insertion of the inside fastener unit into the outside fastener unit, the inside fastener unit is then tightly fastened by the outside fastener unit to achieve the purpose of resistance to water at the sealing.
2. The sealing structure capable of withstanding water pressure of claim 1, wherein, fitted outside the outside fastener unit is optionally an additional C-shaped flexible exterior wrapping strip that tightly envelops the outside fastener unit.
