Further, described sealing cover body internal cavities is divided into two parts, and what be communicated with described discharging opening place is the first cavity, between the first cavity and the second cavity, is provided with baffle plate, has small opening on baffle plate, and described small opening is opened can be at baffle plate centre or two ends.
Further, the curved or arch in described the first cavity top, in the middle of being conducive to when toppling over material, material be converged in.
Described baffle plate can prevent that the material in packaging bag is too fast topples over out, and when packaging bag is used for filling laundry soap powder, baffle plate can also prevent that packaging bag opening from being bedewed by water, further prevents that bag interior laundry soap powder is rotten.
Further, for fear of material is too fast, topple over, described packaging bag opening is greater than baffle plate small opening.
Further, for fear of described cover plate, stop that material pours out swimmingly, the angle that described cover plate is opened is greater than 130 °.
Further, described cover plate outside face is provided with projection, and accordingly, sealing cover body is provided with knock hole, when cover plate turn to maximum angle after opening described in projection embed in described knock hole, described cover plate is fixed on sealing cover body.
Further, described Pressure sensitive adhesive tape comprises adhesive area and draws stripping end.
Further, district is thrust in described Pressure sensitive adhesive tape adhesive area, thrusts the end in district and the indentation line overlaid in packaging bag.
In packaging bag, stamp out the indentation line of opening, opening indentation line surface is covered by the adhesive area of Pressure sensitive adhesive tape, and while opening, the stripping end that draws that hand pinches non-drying glue pulls open, and the part that adhesive area stamps out indentation line place is peeled off mutually with packaging bag, thereby opens the package.
Further, for the ease of opening the package, prevent that Pressure sensitive adhesive tape is hidden in and in sealing cover body, be difficult to take out, will described in draw stripping end to be positioned in described the second cavity.
During use, the stripping end of drawing that hand pinches non-drying glue pulls open, and the part that adhesive area stamps out indentation line place is peeled off mutually with packaging bag, thereby opens the package opening, uses sealing cover body is covered to the material that can make in packaging bag not make moist.
Implement the utility model, there is following beneficial effect:
Adopt the utility model, can realize double-layer seal, Pressure sensitive adhesive tape can be given packaging bag opening easily, curved or the arch in sealing cover body the first cavity top, in the middle of being conducive to material to converge in, baffle plate on sealing cover body can be controlled the speed that material pours out can prevent that material touches on only lightly simultaneously, and the cover plate on sealing cover body can repeat to open and be moistureproof damp proof.

The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.
Sealing structure of packaging bag as shown in Figure 1, comprises Pressure sensitive adhesive tape 1 and with the sealing cover body 2 of cavity, described Pressure sensitive adhesive tape 1 is affixed on packaging bag 3 openings.
Shown in Fig. 2 and Fig. 3, described sealing cover body 2 is arranged on described Pressure sensitive adhesive tape 1, its upper end is provided with discharging opening 221, discharging opening 221 places are provided with the cover plate 222 of flexible connection, described cover plate 222 be take junction 2221 as axle unlatching is with closed, at closure place, by buckle 223 is set at discharging opening, described cover plate is fixed on discharging opening.
Preferably, the present embodiment is also provided with and protrudingly prolongs 224 on described cover plate 222, further plays moisture-proof role.
Described sealing cover body 2 internal cavities are divided into two parts, and what be communicated with described discharging opening place is to be provided with baffle plate 23 between the first cavity 21, the first cavitys 21 and the second cavity 22, has small opening 231 on baffle plate.
Preferably, the curved or arch in described the first cavity 21 tops, in the middle of being conducive to when toppling over material, material be converged in.
Preferably, in the present embodiment, described small opening 231 can be opened in the middle of baffle plate.
Described baffle plate 23 can prevent that the material in packaging bag is too fast topples over out, and when packaging bag is used for filling laundry soap powder, baffle plate can also prevent that packaging bag opening from being bedewed by water, further prevents that bag interior laundry soap powder is rotten.
Further, for fear of material is too fast, topple over, described packaging bag opening is greater than baffle plate and leaks 23.
Preferably, for the ease of opening the package, prevent that Pressure sensitive adhesive tape 1 is hidden in and in sealing cover body 2, be difficult to take out, will described in draw stripping end to be affixed in described the second cavity 22.
As shown in Figure 4, described cover plate 222 outside faces are provided with projection 2222, and accordingly, sealing cover body is provided with knock hole 2223, described in when cover plate 222 turn to maximum angle after opening, projection 2222 embeds in described knock hole 2223, and described cover plate 222 is fixed on sealing cover body.
Preferably, for fear of described cover plate 222, stop that material unimpededly pours out, the angle that described cover plate 222 is opened is greater than 130 °.
Fig. 5 is the utility model sealing cover body the second example structure schematic diagram, and the number of projection described in the present embodiment 2222 and described knock hole 2223 is respectively 2.
Fig. 6 is the utility model Pressure sensitive adhesive tape schematic diagram, and as shown in the figure, described Pressure sensitive adhesive tape 1 comprises adhesive area 11 and draw stripping end 12, and district 111 is thrust in adhesive area 11, thrusts the end in district 111 and the indentation line overlaid in packaging bag.
In packaging bag, stamp out as shown in Figure 3 the indentation line 3 of opening, opening indentation line is used adhesive area 11 sealing that covers of Pressure sensitive adhesive tape around, the size on 11 surfaces, described adhesive area is slightly larger than opening indentation line, make Pressure sensitive adhesive tape have enough viscous forces along the indentation line strip off of punching in packaging bag, to make bag form discharge openings, while pulling open, the described stripping end 12 that draws pulls open Pressure sensitive adhesive tape along thrusting district 111, described in while pulling open, the edge of adhesive area 11 openings is identical with indentation line edge in packaging bag, the periphery of Pressure sensitive adhesive tape adhesive area 11 keeps being close to the edge of discharge openings, the degree of finish that keeps open circumferential, while avoiding toppling over material, open circumferential is infected with material because of residual non-drying glue.
During use, open the cover plate of sealing cover body, expose the stripping end of drawing of Pressure sensitive adhesive tape, with hand one, draw, opening that can strip off packaging bag surface, pours out after material, again cover plate press seal.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
