Abstract

The utility model relates to an inflatable body which has the advantages of labor saving and convenience for inflation. The inflatable body comprises two plastic layers, the peripherical sides of the two plastic layers are sealed, and the two plastic layers are provided with a ventilating part. The utility model is characterized in that the peripherical sides of the two plastic layers are sealed with a sealing end, and the sealing area of the sealing end is provided with the ventilating part. The ventilating part comprises an upper guide layer, a lower guide layer and a guiding layer, wherein, the guiding layer is positioned between the upper guide layer and the lower guide layer, and thus two sets of joint structure are formed. One joint structure is a sealing area composed of a plastic layer, the upper guide layer and the guiding layer. The other joint structure is a sealing area composed of the other plastic layer and the lower guide layer. The edges of the upper guide layer and the lower guide layer are sealed, the ventilating part is sealed inside, and the guide layer is provided with an upper outer lip. The lower guide layer is provided with a lower outer layer which exposes outside the sealing end, and the outer surfaces of the upper outer lip and the lower outer lip are respectively provided with a separation layer of an elliptical hole. The utility model is suitable for toy occasions.

Description

The inflation body

The utility model relates to the inflation body of balloon, air cushion, inflatable toys one class.

The inflation body of existing toy etc., its structure generally are by two halfbodies periphery hot melt be combined into, and a puff port and blocking thereof are arranged.Because puff port protrudes about one centimeter of surface, again that its plug is recessed after filling, need blow to keep here with mouth and adhere to that sealing is air tight just complete for filling, blow the dizzy dim eyesight of people, sometimes be caught unprepared and pinch the still leakage unavoidably of folder puff port, and because of the protrusion of puff port and the structure of thick body, cause volume to dwindle, and carry also inconvenient.

It is good that the purpose of this utility model provides a kind of contractibility, blows, inflation body easy to carry.

The purpose of this utility model is achieved in that the inflation body, and it comprises two plastic layers, sealed knot around it, and a ventilating part is arranged; It is characterized in that: sealed knot has a sealed knot end around two plastic layers, and is provided with ventilating part in the envelope district of sealed knot end; Ventilating part comprises conducting shell on, once a conducting shell and a guide layer, and guide layer is positioned between upper and lower conducting shell and constitutes two groups of combined structures; The one combined structure is the envelope district that is made up of plastic layer, last conducting shell and guide layer, and another combined structure is the envelope district that another plastic layer, following conducting shell are formed; Upper and lower conducting shell edge sealing and ventilating part package be outer lip on interior and guide layer has, and it is outside and at the outside of upper and lower outer lip table that following conducting shell has following convex outer to be exposed to the sealed knot end, respectively is provided with the absciss layer of elliptical aperture.

Above-mentioned design, available gas blow pipe inserts ventilating part and puts on the air, and reaches reduced volume, blows, effect easy to carry.

Below by drawings and Examples the utility model is described further again.

As Fig. 1-3, sealed knot around two plastic layers 1, the envelope district B of sealed knot end 11 establishes ventilating part 6, ventilating part 6 comprises conducting shell 2, following conducting shell 3 and guide layer 4, the edge sealing A of upper and lower conducting shell is with the hot melt combination, in ventilating part 6 is encapsulated in, the last outer lip 41 of guide layer 4 only, the following outer lip 31 of following conducting shell 3 is protruding, and to be exposed to sealed knot end 11 outside and be provided with the absciss layers 5 of elliptical aperture 51 in its outside table.Form enclosure space and constitute venting channels by last two plastic layers 1 by upper and lower conducting

shell

2,3.

As Fig. 4-5, by absciss layer 5 upper and lower

outer lip

41,31 strip ofves are inserted inflation by guide layer 4 by gas blow pipe 7.Elliptical aperture 51 mainly is also can be provided with tether 8 for ease of strip off, and the utility model inflation body can be made various moulding, and with meet requirements, its advantage is: 1. plastic cement lamellar body contractibility is good, and is easy to carry; 2. closed channel can seal automatically, and air-tightness is good; 3. ventilating part is a multilayer, is difficult for poking for gas blow pipe, and it is laborsaving, convenient to blow.

Claims
