Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a glass cup with a metal cover. Background Art

[0002] With the progress of society and the continuous improvement of people's health awareness, people's functional demands for drinking cups, which are necessities of life, are also expanding. Glass cups with metal lids are not only transparent and beautiful, but also do not contain chemicals when used to hold water.

[0003] However, when most of the metal-covered glass cups on the market are in use, after the hot water in the glass cools down, the air inside the glass cup shrinks, and the external pressure is greater than the pressure inside the cup, and the metal cover is difficult to unscrew, causing inconvenience to people's normal use. If the opening method is improper, it is easy to cause the glass cup to break, causing economic losses.

[0004] Therefore, we provide a glass cup with a metal cover to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a glass cup with a metal cover to solve the above-mentioned defects caused by the prior art.

[0006] A metal-covered glass cup comprises a metal cup cover, a pressure relief structure and a glass cup body, wherein the metal cup cover is connected to the cup mouth of the glass cup body, and a sealing ring gasket is placed between the two, and the pressure relief structure is centrally installed on the metal cup cover. The pressure relief structure comprises a connecting pipe and an air outlet pipe, wherein the connecting pipe is coaxially installed at the center of the metal cup cover, and a pair of limiting rings are integrally connected to the inner side of the connecting pipe, the air outlet pipe is slidably connected to the inside of the connecting pipe, and a limiting plate is integrally connected between the pair of limiting rings, a reset spring is sleeved between the limiting plate and the limiting ring on the lower side, a pair of sealing springs are connected to the lower port of the connecting pipe, and a protective cover is connected to the upper port of the connecting pipe.

[0007] Preferably, a first thread is provided on the outer side of the connecting pipe, a second thread is provided on the inner side of the protective cover, and the protective cover and the connecting pipe are connected together by threads.

[0008] Preferably, a third thread is provided on the inner side of the metal cup cover, a fourth thread is provided on the outer side of the cup mouth, and the metal cup cover and the cup mouth are connected together by threads.

[0009] Preferably, an annular hollow chamber is provided on the side of the glass body.

[0010] Preferably, a tea strainer is placed inside the glass body.

[0011] Preferably, a rubber pad is bonded to the bottom of the glass body.

[0012] Preferably, a pair of fixing rings are sleeved on the outer side of the glass body, and a handle is connected between the pair of fixing rings.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The utility model facilitates unscrewing the glass cup by means of the pressure relief structure provided on the metal cup cover. When using the metal-covered glass cup, if the metal cup cover of the glass cup cannot be unscrewed due to the cooling of the hot water, first unscrew the protective cover, then press the air outlet pipe, and push the air outlet pipe to open the closed sealing spring, so that the outside air can enter the glass cup body through the air outlet pipe, so that the internal and external pressures of the glass cup body are balanced. After the air outlet pipe is released, the air outlet pipe can return to the initial position under the action of the reset spring, and the opened sealing spring will be closed again, and finally the metal cup cover on the glass cup body can be easily unscrewed.

[0015] 2. The utility model has the following advantages: the sealing ring gasket can effectively improve the sealing of the metal-covered glass cup to avoid water leakage; the hollow chamber can keep the water inside the glass cup warm to avoid excessive heat loss and affect people's drinking mood; the tea filter can filter the tea leaves to avoid the tea leaves affecting the taste of drinking water; the rubber cushion can protect the glass cup to avoid improper force when placing it and causing the glass cup body to break. With the cooperation of the fixing ring and the handle, it is more convenient for people to take and use the glass cup, which improves the practicality. BRIEF DESCRIPTION OF THE DRAWINGS
