The closing zip-fastener is composed of two zipper tapes which are respectively arranged on the inner lateral walls of a bag opening and compression slider which straddles on the two outer lateral walls of the bag opening. The compression slider is constituted by two compression sheets which are double folded and clapped, a mousing-sheet is extended from the center on the inner top portion of the compression slider, and hook-shaped stopping sheets which take projecting shapes are arranged on the end of the two compression sheets. The utility model utilizes that a mousing-sheet is extended from the center on the inner top portion of the compression slider, and the mousing-sheet is arranged between the two zip-fastener tapes, thereby, the compression slider can only slide between closing tapes without tripping the bag opening. The utility model has the advantages of simple and compact structure, more convenient employment, and excellent sealing effect, which can avoid a missing trouble which is caused by dropping the compression slider.
Description
Technical field
The utility model relates to a kind of compressed bag, is meant especially a kind ofly to be applicable to that clothing is deposited and with the compressed bag of sealing slide fastener.
Background technology
At present, vacuum clothing compressed bag has been widely used in the daily life, soft article such as the clothes that it can be deposited needs, quilt, woollen blanket are compressed to 1/3 of original volume, reach and save the space, prevent effects such as clothing makes moist, goes mouldy, damages by worms, be very suitable for clothing etc. and deposit, carry and keeping.Because easy to use, the low price of vacuum clothing compressed bag more and more is subjected to people's favor.
In the past, the employed clothing compressed bag of people comprised by two sealing plastic film hot pressings and forms the bag of containing cavity and be arranged on the slide fastener that seals of bag open end.Wherein the slide fastener that seals of bag is made up of two zipper strips of difference hot pressing on sack two madial walls, article two, zipper strip is provided with sealing band and the seal groove that cooperatively interacts, by the free-hand mode of pushing sealing band and seal groove are meshing with each other, sack is in air-tight state.But free-hand mode of directly pushing was both time-consuming, effort, caused easily again not push to make the sack sealing effectiveness not good really.
For this reason, people developed a kind of be used to replace free-hand push seal slide fastener, it includes zipper strip and straddles on sack two lateral walls and can make sealing band and the intermeshing pressing slide block of seal groove on the zipper strip, wherein the pressing slide block is to be the pressing sheet that the doubling pincers closes by two to constitute, utilize the squeese pressure of two pressing sheet medial surfaces, sealing band and seal groove are meshing with each other.Though can improving, the pressing slide plate of this structure sealed the free-hand defective that is produced of pushing of slide fastener dependence in the past, but still have following shortcoming in the use: improper because of user's application of force easily during use, cause slippage and walk and make sealing band and seal groove unbalance stress or produce deviation; In addition, when the pressing slide block moves to the sack end, very easily break away from sack, therefore the pressing slide block of this structure all is that just direct end from sack drags down after pressing when in use, get at fit when use next time, if not the pressing slide block is easy to the landing loss, uses inconvenient.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure in order to solve the weak point that above-mentioned prior art exists, and uses conveniently, and can prevent that band that the pressing slide block comes off from sealing the compressed bag of slide fastener.
For achieving the above object, the utility model adopts following scheme: a kind of band seals the compressed bag of slide fastener, comprise by two and seal the slide fastener that seals that the plastic film hot pressings form the bag of containing cavity and are arranged on the bag open end, wherein offer air gate on the bag, sealing slide fastener is made up of the pressing slide block that is separately positioned on two zipper strips on the sack madial wall and straddle on sack two lateral walls, described pressing slide block is the pressing sheet that the doubling pincers closes by two and constitutes, extending in the middle of the inside top of pressing slide block has anti-flake, and the end of two pressing sheets is provided with the hook-type that is overshooting shape and ends sheet.
The utility model further is set to, and the medial surface of described two pressing sheets is provided with and the cooresponding pressing convex tendon of sealing band and seal groove position, has extended lamellar body to both sides on its lateral surface.
Place, described bag bottom is provided with outlet passageway, it is by spaced apart formation of full heat-sealing line that partly seals line and bag bottom that is arranged on the bag lower end, described air gate is opened on the sealing plastic film that is positioned at the outlet passageway position, and outlet passageway communicates with the external world by air gate.
Described air gate staggers with the opening that partly seals line and is arranged on the both sides of outlet passageway.
The beneficial effects of the utility model are: the utility model is compared with original technology, by in the middle of the inside top of original pressing slide block, extending anti-flake is arranged, anti-flake is installed between two zipper strips, and limit the sliding distance of pressing slide block, thereby the pressing slide block can only be slided between the involution band and can not break away from sack by the involution band on the sack two ends; The hook-type that is arranged on the end of pressing sheet ends sheet 223, and one side is avoided sealing band and seal groove unbalance stress or generation deviation to cause slippage and walked; Increase the anticreep effect of pressing slide block on the other hand; Be arranged on the pressing convex tendon on the medial surface of pressing sheet, can increase the squeese pressure of pressing sheet, sealing band and seal groove fast speed are fastened, increase sealing effectiveness zipper strip; Extended lamellar body to bilateral symmetry on its lateral surface,, made things convenient for the operation of user's finger grip in order to increase the usable floor area of pressing sheet.In addition, offer small-sized air gate being positioned on the sealing plastic film wall of outlet passageway position, to arrive comparatively ideal sealing effectiveness.The utility model is simple and reasonable for structure, use convenient, good sealing effect, and can prevent the pressing slide block from coming off and the trouble that causes losing.
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
