Description

A kind of novel heat insulation bag

Technical field

The utility model is related to case and bag technical field, more particularly to a kind of novel heat insulation bag.

Background technology

Insulation bag, belongs to one kind of outdoor case and bag, is for containing various foods and keeping food temperature and the bag of freshness Bag, it can be used for refrigeration, can such as be put into ice cube, cold drink cold items, therefore thermal protection cold insulation is that insulation bag is most basic Function.

In the prior art, insulation bag typically has heat-insulation layer, and heat-insulation layer is wrapped up by inner layer cloth and outer layer cloth, outside Also form the half opening installed for slide fastener on layer cloth, formed above half opening and covered, half opening it is formed below successively by outside, The moist closet that heat-insulation layer and inner side are surrounded, pulls slide fastener to open or close lid, takes thing very convenient from moist closet.For For one insulation bag with excellent heat-insulating property, on the basis of using heat-insulation layer, the sealing of moist closet is also insulation Key, existing insulation bag inner layer cloth and outer layer cloth sutured at opening by way of sewing, inner layer cloth and outer layer Cloth is also formed by the suture of some fritter clothes, and existing insulation bag also has following defect：

First, the inner layer cloth and outer layer cloth combined by way of fare is sutured, its sealing effectiveness is simultaneously bad, in suture Place leaves pin hole, inner layer cloth and outer layer cloth can not complete seamless combination, inevitably reduce that insulation wraps is close Feng Xing, gap and inner air formation convection current of the extraneous air easily by pin hole or inside and outside interlayer, causes the internal temperature of insulation bag Degree change, heat insulation effect is not good；

When the 2nd, depositing cold items (such as ice cube), in the case of occurring in that cross-ventilation, ice melting or air setting, Cause the water in heat-insulated cavity to flow to heat-insulation layer along gap to flow out from outer layer, internal cold air may also result in outer layer in addition There is the situation of condensation vapor in suture, and above-mentioned situation causes the reduction of heat-insulation layer service life, and ectonexine suture aging It is easily caused gap further to expand, reduction insulation bag useful life；

Three, the inner side of existing insulation bag is usually directly sutured with outer layer at opening, and inner layer cloth is on moist closet top Opening at cross section much larger than it in the cross section of moist closet bottom, cause inner side cloth the problem of there is fold, and have The insulating article inconvenience of regular placement is needed to place a bit.

Utility model content

Therefore, for it is above-mentioned the problem of, the utility model proposes a kind of simple in construction, neat appearance, high insulating effect Insulation bag.

To achieve the above object, the utility model employs following technical scheme：A kind of novel heat insulation bag, including inclusion and With the clad on the upside of inclusion along welding, the inclusion is sequentially provided with inner bag, heat-insulation layer and outer bag from the inside to the outside, and the inner bag includes The inner bag bottom that inner bag encloses and connect with inner bag weld all around, the outer bag includes the outer bag bottom that outer bag is enclosed and connect with outer bag weld all around, described interior Bag enclose it is upper along welding one convex edge, the convex edge include with inner bag place along welding convex edge bottom, be welded in it is convex on the bottom of convex edge Peripherally with enclosed in convex edge, heat-preservation cotton is provided between being enclosed in convex edge periphery and convex edge, the convex edge periphery in convex edge with enclosing Convex edge lid is also welded with above heat-preservation cotton, the convex edge is enclosed by being welded to connect with outer bag.

Further improve, a convex edge lid gusset welds along its side along direction in the convex edge side of covering, and the convex edge passes through Convex edge lid gusset is welded to connect with the upper edge that outer bag is enclosed.

Further improve, the clad includes the clad body provided with heat-preservation cotton and the lid above clad body Body, the clad body is in the range of the orthographic projection of lid, and the lid extends to form free margins to four sides, and one of them is certainly Weld on the upper edge enclosed by side and outer bag.

Further improve, one layer of PE plate is set above the lid, and the PE plates and foregoing free margins sewing are integral.

Further improve, the PE plates and free margins are by strap parcel and sewing is integral.

Further improve, the longitudinal sectional shape of the clad body is inverted trapezoidal.

Further improve, the clad is provided with VELCRO in free margins lower surface, and the convex edge, which is covered, to be provided with and magic The corresponding Velcro of patch.

Further improve, the clad is provided with the draw ring for being used for opening clad near VELCRO.

By using preceding solution, the beneficial effects of the utility model are：The utility model is by the way of welding Make between inclusion and clad, connect more firm between inner bag and outer bag, it is to avoid the line aging of traditional vehicle line suture way, fracture The problem of, air-tightness is good, and thermal and insulating performance is good.The utility model is by the convex edge of setting, and by clad body longitudinal profile Inverted trapezoidal is shaped to, when clad is covered on inclusion, facilitates side and the convex edge fitted seal of clad body, further Strengthen the sealing of insulation bag；Meanwhile, the bonding force of Velcro and VELCRO is conducive to fixing the position of clad；Further, lead to Setting draw ring is crossed, facilitates consumer to open clad.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

The utility model is further illustrated in conjunction with the drawings and specific embodiments.
