CN201452569U - Double-layer glass cup - Google Patents

Abstract

The utility model provides a double-layer glass cup which is characterized in that an inner glass cup is sleeved with an outer glass cup; the neck parts and the bottom pars of the inner and the outer glass cups are sintered and sealed; a clearance is left between the peripheries of the two glass cups, and the clearance is filled with rarefied air; the bottom parts of the inner and outer glass cups are thickened, and the glass cup is provided with a cover. The utility model has the advantages that the clearance is left between the inner and the outer glass cups, and the rarefied air filled inside can act the part of thermal insulation; in addition, the bottom parts of the inner and outer glass cups are welded and fused together, thereby overcoming the defect that the inner glass cup is easily broken off from the cup neck section because of oscillation or shake during the processes of transportation, carrying and utilization of the product; and the product has the advantages of simple structure and elegant appearance.

Description

A kind of double-layer glass

Technical field

The utility model relates to a kind of double-layer glass.

Background technology

Common glass generally is the single-glass cup, its shortcoming is that heat-insulating property is poor, therefore multiple double-layer glass with heat-insulating property has appearred in the market, be with the internal layer of cup and outerly merge in the rim of a cup welding, other position of ectonexine does not produce connection mutually, form hollow layer in the middle of the interlayer of ectonexine, its shortcoming is that product causes glass internal layer to fracture from the cup neck easily because shake or shake in transportation, carrying, use.

Summary of the invention

In order to solve the shortcoming of above-mentioned cup, the utility model provides a kind of double-layer glass, it is that an outer glass is being overlapped in an interior glass outside, inside and outside glass is in its neck and the sealing of bottom sintering, leave the gap around two glasses, do not contact mutually, and be filled with rarefied air, the bottom of inside and outside glass thickeies, and glass has lid.The utility model has the advantages that, because it is gapped between the inside and outside glass, in the rarefied air that fills, can play heat-blocking action, in addition because the welding of inside and outside glass bottom merges, so overcome product in transportation, carrying, use because concussion or vibrations cause in the defective that fractures from the cup neck easily of glass, this product structure is simple, and is elegant in appearance.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model is overlapping outer glass 3 by interior glass 1, and inside and outside glass is in its glass neck 4 and the sealing of bottom 5 sintering, leave gap 2 around the inside and outside glass, and be filled with rarefied air, and glass bottom 5 thickeies, and glass has lid 6.

Claims (1)

1. double-layer glass, it is characterized in that, this glass is that an outer glass is being overlapped in an interior glass outside, inside and outside glass is in its neck and the sealing of bottom sintering, leave the gap around the inside and outside glass, do not contact mutually, and be filled with rarefied air, the bottom of inside and outside glass thickeies, and glass has lid.
