Background technique

Hot water cup is usually the container that people contain liquid, usually can be used to have tea, drinks water, drinks coffee, having a drink.Water Cup is a kind of vessel in most cases being used to contain liquid.Plastic cement, glass, porcelain or stainless steel making are usually used, in dining room It is packaged beverage, then commonly uses dixie cup or glue cup contains.How cylindrical cup is, top-open, hollow, for storage.Because cup is open, Liquid is easily by surrounding dust pollution in cup, so placing when for a long time, Multipurpose cup cover is covered.The cup for containing hot drink has handle, this Sample is convenient to use.In the different field and culture of various countries, the shape of cup has a different, it may be said that culture determines shape. Also there are many kinds of classes, such as vacuum cup for cup, and open cup, go in ring cup, Intelligent water cup, and the cold insulation cup that technology uses at present is internal Material uses low-density polyethylene material, and this kind of material cannot bear the high temperature more than 60 degrees Celsius, while such material smell Greatly, it be easy to cause and installs liquid odour variation, liquid is drunk in pollution.

Utility model content

The purpose of this utility model is to provide a kind of hollow cold insulation cups, to solve the problems of the prior art.

To achieve the above object, the utility model provides the following technical solutions: a kind of hollow cold insulation cup, including cup body, The bottom setting of the cup body is fluted, and cup lid is provided at the top of the cup body, internal screw thread is provided in the cup lid, described External screw thread is provided at the end opening of cup body, the cup body is made of internal layer, middle layer and outer layer, and the internal layer is poly- using food-grade Propylene material blow molding, middle layer use radiation protection thin film material plating aluminum, and outer layer uses the anti-skidding polypropylene material of food rank, institute Internal layer, middle layer and outer layer is stated to form using laser welding technology.

Preferably, the middle layer is provided with interlayer film, and film uses digital printing technology.

Preferably, hollow gap is provided among the internal layer and outer layer.

Preferably, the cup lid diameter is 74mm.

Compared with prior art, the utility model has the beneficial effects that the utility model production is rationally, and it is easy to use, lead to Middle layer interlayer film is crossed, using digital printing technology, layout is printed into radiation protective film surface, by printed film It cuts, internal layer body is nested into radiation protective film by the barreled structure for being hot pressed into radiation cup body size, is reloaded into outer layer cup body It is interior, by laser welding, internal layer and outer layer are welded together, have hollow gap among internal layer and outer layer, passes through hollow technology Heat transfer, while middle layer radiation protective film tissue heat radiation are reduced, polypropylene material is the non-conductor of heat, can prevent hot biography It passs, reaches cold insulation effect by above several measures, by using internal layer polypropylene material and middle layer metallized film, cup is without gas Taste further promotes cold insulation effect.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Please refer to Fig. 1~3, in the utility model embodiment, a kind of hollow cold insulation cup, including cup body 1, the cup body 1 Bottom 2 be arranged fluted 3, the top of the cup body 1 is provided with cup lid 4, and internal screw thread, the cup are provided in the cup lid 4 External screw thread is provided at the end opening of body 1, the cup body 1 is made of internal layer 11, middle layer 12 and outer layer 13, and the internal layer 11 is adopted With food-grade polypropylene material blow molding, middle layer 12 uses radiation protection thin film material plating aluminum, and outer layer 13 is anti-using food rank Sliding polypropylene material, the internal layer 11, middle layer 12 and outer layer 13 are formed using laser welding technology.

The middle layer 12 is provided with interlayer film, and film uses digital printing technology, in the internal layer 11 and outer layer 13 Between be provided with hollow gap, 4 diameter of cup lid is 74mm.

The working principle of the utility model is: by 12 interlayer film of middle layer, using digital printing technology, by layout Radiation protective film surface is printed to, printed film is cut, is hot pressed into the barreled structure of radiation cup body size for internal layer 11 Body is nested into radiation protective film, is reloaded into 13 cup body of outer layer, and by laser welding, internal layer 11 and outer layer 13 are welded on Together, there is hollow gap among internal layer and outer layer, heat transfer, while 12 radiation protective film tissue of middle layer are reduced by hollow technology Heat radiation, polypropylene material are the non-conductors of heat, can prevent hot transmitting, reach cold insulation effect by above several measures, By using 12 metallized film of 11 polypropylene material of internal layer and middle layer, cup odorlessness, the cold insulation effect further promoted.

It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting Related claim.
