Description

Technical Field

[0001] This utility model relates to cup lid structure, and in particular to an externally cooled cavity thermoformed cup lid. Background Technology

[0002] A blister cup lid is a plastic cup lid manufactured using a vacuum forming process. Blister cup lids are used to cover paper or plastic cups for taking away beverages such as milk tea, coffee, soft drinks, and cola. Blister cup lids are made by softening thermoplastic sheets under light, then adsorbing them onto the forming surface of a blister mold using negative pressure, and finally shaping them through cooling and cutting processes.

[0003] In the use of existing blister cup lids, the lids are placed over the opening of paper or plastic cups to achieve a relative seal and prevent the beverage from spilling. To improve the taste of the beverage and cool it down, ice cubes are usually added to the cup. However, for drinks such as lattes, milk tea, and pure fruit juice, adding ice will reduce the sweetness or concentration. Although existing technologies have replaced this with pre-cooled metal ice cubes, the cost is relatively high. Utility Model Content

[0004] The purpose of this invention is to provide an external cooling cavity blister cup lid that cools the beverage inside the cup while preventing ice from coming into contact with the beverage.

[0009] The edge fastening part includes a first arc-shaped groove, which is arranged around the circumference of the cover and fits into the opening side of the cup.

[0010] Preferably, the projection shape of the protrusion and the cooling cavity on the upper surface of the cover is semi-circular, and the protrusion and the cooling cavity are symmetrically arranged.

[0011] By adopting the above technical solution, which occupies half of the space, firstly, the space of the cooling chamber is increased, and secondly, it is convenient to insert the suction tube without interference.

[0012] Preferably, the protrusion includes a top plane, an upper semi-annular side surface, and an inclined side surface. The upper semi-annular side surface is concentrically arranged with the cover body and is inclined outward. The bottom of the upper semi-annular side surface is connected to the edge buckle portion, the top of the upper semi-annular side surface is connected to the outer circumferential side surface of the top plane, the inner side of the top plane is connected to the top of the inclined side surface, and the bottom of the inclined side surface is connected to the cover body.

[0022] Preferably, a mixing hole is provided at the position where the inner wall of the cooling chamber mates with the sub-cover, and the mixing hole is provided through the side wall of the cooling chamber.

[0023] By adopting the above technical solution, when the secondary lid is opened, the melted ice water in the cooling chamber enters the cup through the mixing hole, adjusting the temperature, concentration, and taste of the beverage in the cup.

[0024] Preferably, the opening side of the cup body is folded outward to form a positioning ring, which is concentrically arranged with the cup body. The side buckle also includes a concentrically arranged annular lower folded edge, an annular upper folded edge, and a slot, which is formed by the annular lower folded edge, the annular upper folded edge, and a first arc-shaped groove. The slot cooperates with the positioning ring.

[0025] By adopting the above technical solution, the cup lid is more firmly fixed to the cup body, preventing the cup lid from falling off and avoiding leakage.

[0026] In summary, compared with existing technologies, the cup lid uses an external cooling chamber at the top to hold ice cubes. The thermoformed wall of the lid not only transfers temperature and cools the beverage inside the cup, but also prevents ice cubes or ice water from directly mixing with the beverage, thus avoiding a decrease in beverage concentration. Furthermore, the lid is adaptable to different cup structures, has a lower cost, is structurally stable and leak-proof, is easy to use, and facilitates the slow melting of ice cubes, extending the cooling time.

[0035] Example:

[0036] like Figures 1 to 5 As shown, an external cooling cavity thermoformed cup lid includes a lid body 1 made of thermoplastic thermoforming material, a cup body 5 made of paper or plastic, and a structure of the lid body 1 consisting of a protrusion 2 and a cooling cavity 3 at the top. The cooling cavity 3 opens upward to form a placement opening 31 for placing ice cubes. The edge of the lid body 1 is connected to the top of the cup body 5 by a thermoformed edge buckle 6.

[0037] like Figure 4 As shown, the protrusion 2 is located on one side of the top of the cover 1, and the cooling cavity 3 is located on the other side of the top of the cover 1. The projection shape of the protrusion 2 and the cooling cavity 3 on the upper surface of the cover 1 is semi-circular. The protrusion 2 and the cooling cavity 3 are symmetrically arranged. The difference is that the protrusion 2 protrudes upward and the top of the protrusion 2 is higher than the surface of the cover 1. The cooling cavity 3 is formed by the surface of the cover 1 being recessed downward through a vacuum forming process.

[0038] like Figures 1 to 4As shown, the protrusion 2 is used to raise the position of the straw opening 22 and reduce the tilt angle when drinking, thereby preventing the ice water in the cooling chamber 3 from flowing out after tilting. The specific structure of the protrusion 2 includes a top plane 23, an upper semi-annular side 24 and an inclined side 25. The upper semi-annular side 24 is concentrically arranged with the cover 1 and is inclined outward. The bottom of the upper semi-annular side 24 is integrally formed with the edge buckle 6. The top of the upper semi-annular side 24 is integrally formed with the outer circumferential side of the top plane 23. The inner side of the top plane 23 is integrally formed with the top of the inclined side 25. The bottom of the inclined side 25 is integrally formed with the cover 1. At the same time, a positioning groove 21 is provided in the center of the top plane 23, and the straw opening 22 is located in the positioning groove 21.

[0039] like Figures 1 to 5 As shown, the placement opening 31 is located at the top of the cooling chamber 3, which is used to place ice cubes. The height of the cooling chamber 3 is one-fifth to one-third of the height of the cup body 5, ensuring that the cooling chamber 3 can contact the beverage inside the cup body 5 for heat exchange. The specific structure of the cooling chamber 3 includes a bottom plane 32, a lower half-ring side 33, and a vertical surface 34. The bottom plane 32 is semi-circular. The top of the lower half-ring side 33 is vacuum-formed to the edge of the placement opening 31, and the bottom of the lower half-ring side 33 is vacuum-formed to the bottom plane 32. The top of the vertical surface 34 is vacuum-formed to the placement opening 31, and the bottom of the vertical surface 34 is vacuum-formed to the bottom plane 32. To facilitate demolding, the lower half-ring side 33 is inclined inward.

[0040] The edge fastener 6 includes a first arc-shaped groove 61, which is arranged around the circumference of the cover 1 and fits into the opening side of the cup body 5.

[0041] like Figure 2 and Figure 3 As shown, a secondary cover 41 is provided on the placement opening 31. The secondary cover 41 cooperates with the placement opening 31 and is snapped into the cooling cavity 3 from above the placement opening 31. Specifically, the snapping structure is as follows: an arc-shaped positioning strip 4 is provided on the inner wall of the cooling cavity 3. The arc-shaped positioning strip 4 surrounds the cooling cavity 3 and protrudes from the inner surface of the cooling cavity 3. The longitudinal section of the arc-shaped positioning strip 4 is semi-circular. A second arc-shaped groove 42 is provided on the secondary cover 41 to cooperate with the arc-shaped positioning strip 4. At the same time, in order to keep or place dipping sauces such as ketchup cold, the top of the secondary cover 41 is recessed downward to form a receiving groove 44. The depth of the receiving groove 44 is 2-5cm. In order to facilitate the removal and positioning of the secondary cover 41, the top of the secondary cover 41 extends outward to form a fixing edge 43.

[0042] like Figure 3As shown, in order to pour the ice water in the cooling chamber 3 back into the cup body 5, when the secondary cover 41 is opened, the mixing hole 35 at the position where the inner wall of the cooling chamber 3 matches the secondary cover 41 is opened. The mixing hole 35 is set through the side wall of the cooling chamber 3, so that the ice water can mix with the beverage in the cup body 5.

[0043] like Figure 3 As shown, in order to fix the cup body 5 and the lid 1, the opening side of the cup body 5 is folded outward to form a positioning ring 51. The positioning ring 51 is concentrically arranged with the cup body 5. The side buckle part 6 also includes a concentrically arranged annular lower folded edge 62, annular upper folded edge 63 and a groove 64. The groove 64 is surrounded by the annular lower folded edge 62, the annular upper folded edge 63 and the first arc groove 61. The groove 64 cooperates with the positioning ring 51 so that the positioning ring 51 is embedded in the receiving groove 44, thereby improving the sealing and connection effect.

[0044] Working principle:

[0045] The cup body 5 is suitable for storing beverages that need to be kept cold for a long time without reducing their concentration, such as iced coffee or milk tea. The lid 1 is connected to the positioning ring 51 of the cup body 5 via the side buckle 6. When taking it out, ice cubes are placed into the cooling chamber 3 through the placement port 31, and then the secondary lid 41 is closed. When drinking, simply insert the straw into the straw hole. When you need to drink the ice water in the cooling chamber 3 or adjust the concentration in the cup, open the secondary lid 41 and tilt the cup body 5, and the ice water will enter the cup body 5 through the mixing hole.
