Abstract

Provided is a PE double-layer vacuum cup for outdoor use, which comprises a cup body and cup cover. The cup body is formed by connecting an inner container and housing in a heat welding manner. A layer of aluminium foil is additionally arranged between the inner container and the housing. A plurality of bump or lattice structures are arranged on the outer wall of the inner container, and the structures ensure a minimum thickness of an air layer. A round table facet is disposed under a cup mouth of the inner container. A round mouth of the housing is provided with an inward contracting mouth before welding, and the contracting mouth contracts after heating and is integrated with the round table facet of the inner container in a welded manner. The PE double-layer vacuum cup can effectively prevent water quality from changing caused by solar radiation, has characteristics of thermal insulation, fresh keeping and being convenient to carry, and is especially suitable for outdoor usage as a sport kettle, etc.

Description

PE double-layer heat insulation cup

Technical field

The utility model relates to a kind of water tumbler, the double-layer heat insulation cup that particularly a kind of PE material is processed.

Background technology

The double-layer heat insulation water tumbler has an air layer or vacuum layer between inner bag and the shell, can reduce scattering and disappearing of heat, has the effect of heat-insulation and heat-preservation.Double-layer heat insulation water tumbler on the market adopts glass, the stainless steel strengthened to process mostly, and the glass water tumbler is attractive in appearance, but frangible, is afraid of bump; The stainless steel water tumbler is very heavy, is inconvenient to carry.The double-deck water tumbler that also has common plastics to process on the market, when water in full bloom or acidic beverages, plastics are prone to decompose aging, and long-term drinking is unfavorable to health.

PE material formal name used at school polyethylene, nontoxic, than common plastics acid-alkali-corrosive-resisting more, high temperature resistant, plasticity is good, can be used for packaging for foodstuff and makes the micro-wave oven tableware.But the PE material can not stop that to rays such as ultraviolet ray, infrared rays the water tumbler of directly using the PE material is in outdoor application, and wherein stored liquid is under solar radiation, and water quality can change, and freshness date is very short when especially depositing fruit juice class, milk class beverage.

Summary of the invention

The utility model technical problem to be solved is: provide a kind of can be at the PE of outdoor application double-layer heat insulation cup, can effectively prevent solar radiation and make water quality rotten to have insulation, fresh-keeping, the characteristics that are convenient for carrying.

The utility model addresses the above problem the technical scheme that is adopted: a kind of PE double-layer heat insulation cup, comprise cup and bowl cover, and cup is formed by connecting through thermal weld on inner bag and shell, it is characterized in that having increased between inner bag and the shell one deck aluminium foil layer.

A plurality of convex dot shapes or lattice-shaped structure are arranged on the outer wall of said inner bag, and salient point has guaranteed the minimum thickness of air layer.

On the said case surface anti-skid design is arranged.

Said shell is processed for the clear PE material, can see the inner foil layer.

One round table surface is arranged under the rim of a cup of said inner bag, and there is an inside closing at the shell round mouth place before the welding, and round table surface of this close up heating after-contraction and inner bag is integrally welded.

Compared with prior art, the advantage of the utility model is: simple in structure, be easy to processing; Double-deck cup has heat insulation function, and the aluminium foil layer in the cup can block sunlight shine the liquid of being adorned in the cup with ray, has fresh-keeping function; Cup has adopted the PE material, and transparent shell can also be protected the floral designs on the aluminium foil, and is light solid; Elegant in appearance, carry when being particularly suitable for out on tours, motion.

The specific embodiment

Embodiment to the utility model further describes below in conjunction with accompanying drawing.

As shown in the figure, PE double-layer heat insulation cup comprises cup 1 and bowl cover 2, and cup and bowl cover adopt and be threaded.Said cup comprises inner bag 11, shell 12 and aluminium foil layer 13.

There is a round table surface 111 rim of a cup of inner bag 11 below, round table surface and horizontal plane angle spend between 30 degree 0.When the salient point 112 that a plurality of circles are arranged on the inner bag, bump structure had guaranteed to hold tight cup, the air layer between cup and the inner bag was a minimum thickness.Said salient point also can be made lattice-shaped structure.

Shell is that transparent PE material is processed, and sees through shell and can see the pattern on the inner aluminium foil layer.Anti-skid design 121 is arranged on the shell.Fig. 3 is the shell that does not weld, and there is an inside closing in 122 at the round mouth place of shell, close up with the angle of horizontal plane 50 spend spend to 80 between.As shown in Figure 4, this round table surface 111 that closes up heating after-contraction and inner bag merges.

Before inner bag and the shell welding, put into aluminium foil in advance, the thickness of aluminium foil is between 0.2mm-0.5mm, and the outside of aluminium foil can be printed on decorative pattern and explanation etc.Aluminium foil layer is by transparent PE shell protection, and thermos cup can not scratch or damage decorative pattern when using.

After inner bag and the shell welding, accompany air layer and aluminium foil layer in the wall of cup, can reduce heat and scatter and disappear, play the effect of insulation.Bump structure on the inner bag or lattice-shaped structure, in the time of can preventing that thermos cup is extruded, the air layer attenuation causes the heat in the cup to be transmitted to shell rapidly.Aluminium foil layer can stop the ray in sunlight and the environment to get in the water body effectively, has played fresh-keeping effect, and is when especially holding beverage such as fruit juice, milk, longer than ordinary movement water tumbler fresh keeping time.PE double-layer heat insulation cup also is applicable to preserves ice cube summer.

PE double-layer heat insulation cup, elegant in appearance, weight is light, impact resistance, safety and environmental protection is particularly suitable for making Sports water container, travels out of doors, uses when moving.
