Abstract
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.
Description
- (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 inFIGS. 1 and 2 ), there is azipper 2 fitted inside two sides of the opening, with acover unit 11 extended from one side of the opening, when thezipper 2 is closed, the opening can be rapidly closed, and aflap 11 on one side of the opening will cover the sealing of thezipper 2, the objective is to obstruct water spraying from outside, and prevent water from seeping from the outside of thezipper 2. But that structure serves only the purpose of obstruction. In case water level is higher than the opening, water will flow through theflap 11 into the sealing of thezipper 2, further seeping through thezipper 2, or maybe somezipper 2 has resistance to water, but if water immersing the opening has a larger pressure, there is simply no prevention from water seepage. Therefore, such sealing structure is not capable of preventing water seepage, especially when water has some pressure. - 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.

FIG. 1 is a schematic view of an outside of the prior art of zipper-type sealing structure. -
FIG. 2 is a schematic view of an inside of the prior art of zipper-type sealing structure. -
FIG. 3 is a schematic view of the sealing structure in the present invention. -
FIG. 4 is a section view of the sealing structure in the present invention. - As shown in
FIGS. 3 and 4 , there is azipper 4 fitted to an inside of two sides of aflexible member 3 installed at an opening of a container. Thezipper 4 serves to enable rapid closing of the opening. Theflexible member 3 extends from two sides of theflexible member 3, like butterfly wings, serving to fasten thezipper 4 and combine with a container or a bag to become a water-resistant container or bag. Due to the strength of thezipper 4, the sealing has better tensile strength when the opening is closed and sealed. One margin of the opening has a vertical extension of a pillar-shaped insidefastener unit 31. The vertical extension is abuffer plate 33. Another margin of the opening also extends vertically to become a C-shaped flexible outsidefastener unit 32, its vertical extension also abuffer plate 33 structure, so that theinside fastener unit 31 is capable of accommodating theoutside fastener unit 32, and theoutside fastener unit 32 is capable of wrapping theinside fastener unit 31. Moreover, there is a C-shaped flexibleexterior wrapping strip 5 to wrap theoutside fastener unit 32, while thebuffer plate 33 provides a smooth wrapping space for theexterior wrapping strip 5. - When the
zipper 4 has sealed the opening, with an opening of theoutside fastener unit 32 slightly turned outward, theinside fastener unit 31 is wrapped inside theoutside fastener unit 32; in other words, theoutside fastener unit 32 tightly wraps theinside fastener unit 31. Likewise, the opening of theexterior wrapping strip 5 is slightly turned out, so theoutside fastener unit 32 is easily accommodated inside theexterior wrapping strip 5. By interlocking the wrapping effects of theinside fastener unit 31, theoutside fastener unit 32 and theexterior 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 theexterior wrapping strip 5, tightening theinside fastener unit 31, theoutside fastener unit 32 and theexterior wrapping strip 5, thereby enhancing its water-resistant efficiency. When the sealing is subjected to an outside force, thebuffer plate 33 provides a buffer for the pulling force.
Claims (2)
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.
