Description

Technical Field

[0001] The utility model relates to the field of tea cups, in particular to a tea cup with a double-layer structure. Background Art

[0002] Teacups are commonly used tea drinking utensils. When in use, people can use teacups to drink tea by pouring tea from a teapot into the teacup. As consumer demand changes and increases, teacups are not only rich in variety but also have various structural forms during the design and production stages.

[0003] In the prior art, specifically for tea cups with decorative patterns, during the production and design process, a relief decorative pattern is usually pressed onto the decorative outer shell first, and then the water-holding inner shell and the decorative outer shell are combined together by means of expansion and pressure. This combination method will result in a loose connection between the decorative outer shell and the water-holding inner shell, making the tea cup not durable. At the same time, since the water-holding inner shell and the decorative outer shell are combined together by coaxial straight insertion and expansion, the top connection position of the water-holding inner shell and the decorative outer shell is not processed, resulting in a loose seal at this position. Water can easily enter the space between the water-holding inner shell and the decorative outer shell through this position, which will produce an odor after a long time, and the tea will also corrode the water-holding inner shell and the decorative outer shell. Utility Model Content

[0004] The purpose of the present utility model is to provide a teacup with a double-layer structure in order to solve the above-mentioned problem. The inner water-containing shell is turned outward and combined with the edge to be pressed against the outer top of the outer decorative shell, so that the inner water-containing shell and the outer decorative shell can be firmly combined together to form a teacup structure, replacing the production method of the inner water-containing shell and the outer decorative shell being directly inserted and tightened together. See the following for details.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The utility model provides a teacup with a double-layer structure, comprising an outer decorative shell and an inner water-containing shell, wherein the inner periphery of the outer decorative shell is provided with a first supporting shell for internal support, and the outer periphery of the inner water-containing shell is provided with a second supporting shell for external support, and the second supporting shell of the inner water-containing shell is coaxially sleeved on the inner periphery of the first supporting shell of the outer decorative shell;

[0007] The top of the inner water-containing shell is turned outward to be provided with a bonding edge, and the bonding edge is pressed tightly against the outer top of the outer decorative shell to firmly combine the inner water-containing shell and the outer decorative shell to form a teacup structure.

[0008] Preferably, an anti-scalding ring is coaxially sleeved and pressed on the top outer edges of the outer decorative shell and the supporting shell, and the anti-scalding ring is wrapped by the combined edging by means of extrusion deformation.

[0009] Preferably, the anti-scalding ring is a rubber ring, and the cross-section of the anti-scalding ring is an inverted U-shape.

[0010] Preferably, an anti-slip flange is coaxially extended and fixed to the outer top of the outer decorative shell, and the lower curled edge of the combined edging is pressed from bottom to top and hooked at the bottom of the anti-slip flange.

[0011] Preferably, the outer decorative shell and the inner water-containing shell are both silver shells with an open top and a closed bottom.

[0012] Preferably, the first supporting shell and the second supporting shell are both metal shells with an open top and a closed bottom.

[0013] Preferably, the outer peripheries of the outer decorative shell and the supporting shell 1 are provided with decorative patterns, and the decorative patterns are formed by extruding the inner supporting shell 1 toward the outer decorative shell.

[0014] The above-mentioned teacup with a double-layer structure is used. Specifically, in actual production, since the inner periphery of the outer decorative shell is provided with the supporting shell 1 for supporting from the inside, and the outer periphery of the inner water-containing shell is provided with the supporting shell 2 for supporting from the outside, after the supporting shell 2 of the inner water-containing shell is coaxially sleeved on the inner periphery of the supporting shell 1 of the outer decorative shell, the inner water-containing shell and the outer decorative shell can be firmly combined together to form a teacup structure by turning the top of the inner water-containing shell outward and pressing the combined edge to the outer periphery of the outer decorative shell, replacing the production method of the inner water-containing shell and the outer decorative shell being directly inserted and tightened, ensuring that the inner water-containing shell and the outer decorative shell are firmly combined. At the same time, since the outer edges of the outer decorative shell and the top of the supporting shell 1 are coaxially sleeved with the anti-scalding pressure ring, and the anti-scalding pressure ring is deformed by extrusion The combined edging is wrapped and then, with the help of the combined edging, can wrap and seal the combined position of the outer decorative shell and the top of the inner water-containing shell, which can prevent water from entering the space between the outer decorative shell and the inner water-containing shell through the combined position, avoiding the generation of odor and corrosion of the outer decorative shell and the inner water-containing shell. At the same time, with the help of the heat insulation ability of the anti-scalding pressure ring, the heat conduction speed of the inner water-containing shell to the outer decorative shell can be reduced, thereby having a certain anti-scalding effect when holding the outer decorative shell. Moreover, since the outer top of the outer decorative shell is coaxially extended and fixed with the anti-slip flange, and the lower curled edge of the combined edging is pressed and hooked from bottom to top on the bottom of the anti-slip flange, the outer decorative shell and the inner water-containing shell can be prevented from being accidentally separated by the lower curled edge of the combined edging cooperating to hook the anti-slip flange, further ensuring that the inner water-containing shell and the outer decorative shell are firmly combined.

[0015] The beneficial effects are as follows: 1. The present invention provides a first supporting shell for supporting the inner periphery of the outer decorative shell with a tensioning sleeve, and a second supporting shell for supporting the outer periphery of the inner water-containing shell with a tensioning sleeve. After the second supporting shell of the inner water-containing shell is coaxially sleeved on the inner periphery of the first supporting shell of the outer decorative shell, the inner water-containing shell and the outer decorative shell are firmly combined to form a teacup structure by turning the top of the inner water-containing shell outward and combining the edge to press against the outer periphery of the outer decorative shell. This replaces the manufacturing method of directly inserting and tensioning the inner water-containing shell and the outer decorative shell, thereby ensuring that the inner water-containing shell and the outer decorative shell are firmly combined.

[0016] 2. An anti-scalding pressure ring is coaxially sleeved and pressed on the outer edges of the tops of the outer decorative shell and the supporting shell. The anti-scalding pressure ring is wrapped by a combined edge through extrusion and deformation. The combined edge can then wrap and seal the joint between the outer decorative shell and the top of the inner water-containing shell. This can prevent water from entering the space between the outer decorative shell and the inner water-containing shell through the joint, avoiding the generation of odor and corrosion of the outer decorative shell and the inner water-containing shell. At the same time, the heat insulation capacity of the anti-scalding pressure ring can also reduce the heat conduction rate of the inner water-containing shell to the outer decorative shell, thereby providing a certain anti-scalding effect when holding the outer decorative shell.

[0017] 3. An anti-slip flange is coaxially extended and fixed on the outer top of the outer decorative shell, and the lower curled edge of the edging is pressed and hooked on the bottom of the anti-slip flange from bottom to top. Then, the lower curled edge of the edging is combined with the anti-slip flange to prevent the outer decorative shell and the inner water-containing shell from being accidentally separated, further ensuring that the inner water-containing shell and the outer decorative shell are firmly connected.
