Embodiment 1

[0025] Such as figure 1 As shown, a full crystal glass threaded bowl lid, as an improvement of the present invention, includes a bowl lid main body 1, a lid tongue 2 and a lid eaves 3, and an inner groove 4 is opened between the lid tongue 2 and the lid eaves 3, The inner wall of the cover eaves 3 is provided with threads 5 .

[0026] The main body 1 of the cup lid, the lid tongue 2 and the lid eaves 3 are integrally formed.

[0027] The full crystal glass is specifically high borosilicate glass.

Embodiment 2

[0029] A method for making a cup cover, the cup cover is the cup cover of the above-mentioned embodiment 1, comprising the following steps:

[0030] Assembling dripping equipment and precise control shearing equipment at the outlet of the high borosilicate furnace feedway;

[0031] Set the temperature of the borosilicate glass melting furnace forehearth, material basin and outlet, so that the temperature of the glass when it comes out of the outlet is uniform and the temperature is between 1000°C and 1250°C;

[0032] The weight of the cut piece of glass should be set according to different specifications of the cup lid;

[0033] The glass becomes a segmented or spherical semi-liquid glass through a dropping device and a quantitatively controlled cutting device;

[0034] The mold temperature should be controlled, and the mold temperature should be controlled between 400°C and 800°C during molding. If the temperature of the mold is close to the temperature of the glass, the mo...

Abstract

The invention provides a threaded cup lid made of full-crystal glass and a manufacturing method of the cup lid. The cup lid comprises a main cup lid body, a lid tongue and a lid brim, an inner grooveis formed between the lid tongue and the lid brim, and a thread is arranged on the inner wall of the lid brim. According to the threaded cup lid made of the full-crystal glass and the manufacturing method of the cup lid, the health degree of the cup lid is higher than that of traditional cup lids made of plastic and stainless steel; meanwhile, after the thread of the cup lid is arranged, the cup lid also has the practical convenience in carrying.

Description

technical field [0001] The invention relates to the technical field of cup covers, in particular to a full crystal glass threaded cup cover. Background technique [0002] There are roughly two types of drinking cups or teacups most commonly used by Chinese people. One is a stainless steel thermos cup, and the other is a double-layer borosilicate glass cup. The cup body of the stainless steel thermos cup is made of vacuumized double-layer stainless steel tube, which has a good heat preservation effect. The lid of the stainless steel thermos cup is a combination of stainless steel and plastic fittings, and a leak-proof silicone gasket. The lid surface is stamped from stainless steel and has a threaded interior plastic lid with an annular groove that fits into a leak-proof silicone gasket. That is to say, what really works is the plastic cover. First, the internal thread on the plastic cover is screwed together with the external thread on the rim of the stainless steel cup m...
