Description

Technical Field

[0001] This utility model relates to the field of cold drink cup technology, specifically to a pre-cooled ice drink cup. Background Technology

[0002] In daily life, frozen beverages such as cola, coffee, and beer are usually pre-chilled in the refrigerator. This method requires a long freezing time and takes up a lot of refrigeration space due to the variety of beverages. Alternatively, the beverages can be placed in an insulated box with ice, but this requires pre-prepared ice and a longer cooling time. Another option is to add ice directly to the beverage, but too much ice will dilute the drink and affect the flavor, while a small amount of ice melts quickly and doesn't provide adequate chilling.

[0003] Chinese patent CN210810358U discloses a portable ice cup, including a cup body, which is either a thermos or a cold cup. The cup body has a cooling inner liner with an opening at the top. A lid is provided at the opening of the cup body, and the lid has a spout communicating with the inner cavity of the cup body. The lower end of the lid is threadedly connected to the opening of the cup body, and the lid and the opening of the cup body are sealed together. The upper end of the cooling inner liner is sealed to the inner wall of the lower end of the lid. By freezing the cooling inner liner, beverages can be poured into the inner liner after placing it inside the thermos. Alternatively, the lid can be used to seal the inner liner and the cup body, and canned beverages can be placed inside the inner liner, allowing the cup body and inner liner to function similarly to an ice bucket.

[0004] The aforementioned existing technology features a double-layered cooling liner, with a liquid phase change material filling the sealed interlayer. This liquid phase change material absorbs or releases heat. However, because the liquid phase change material expands and contracts during freezing, prolonged freezing can cause the cooling liner to crack. Furthermore, the cooling liner undergoes deformation during freezing, making it difficult to immediately place in the cup or causing problems with the fit between the lid and the cooling liner.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a pre-cooling ice drink cup that is structurally sound, easy to use, and flexible.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The present invention discloses a pre-cooled iced drink cup, comprising a cup body, a rubber sleeve, and an inner liner. The rubber sleeve is placed inside the cup body, and the inner liner is installed inside the rubber sleeve. A neck sleeve is provided on the upper port of the cup body, and the neck sleeve sequentially abuts and connects the upper port of the inner liner, the upper port of the rubber sleeve, and the upper port of the cup body. Thus, a phase change cavity is formed between the inner liner and the rubber sleeve, and a deformation cavity is formed between the rubber sleeve and the cup body.

[0009] According to the above scheme, the inner liner is made of stainless steel, the sleeve is made of silicone, and the cup body is made of plastic.

[0010] According to the above scheme, the deformable cavity includes a distortion groove, and the bottom of the cup body is provided with several transverse ribs. The several transverse ribs form the distortion groove at the bottom of the cup body, and the bottom of the rubber sleeve can deform towards the distortion groove.

[0011] According to the above scheme, the bottom of the rubber sleeve arches upward.

[0012] According to the above scheme, the deformable cavity further includes an expansion cavity, and the sleeve has a draft angle H, thereby forming the expansion cavity between the outer wall of the sleeve and the inner wall of the cup body.

[0013] According to the above scheme, the inner wall of the cup body has a draft angle K, and the draft angle K is less than the draft angle H.

[0014] According to the above scheme, the inner sidewall of the lower part of the cup body is provided with several vertical stiffeners. The several vertical stiffeners and several horizontal stiffeners are arranged at equal angles around the vertical central axis of the cup body, and the vertical stiffeners and the corresponding horizontal stiffeners form an integrated "L"-shaped structure. The lower part of the rubber sleeve passes through the several vertical stiffeners.

[0015] According to the above scheme, the upper end of the rubber sleeve is provided with an outwardly flared opening, which is fastened to the upper end of the cup body; the upper end of the inner liner is provided with an outwardly rolled pressure ring, which is fastened to the outwardly flared opening; the neck sleeve is provided with a cup mouth ring, the neck sleeve is threadedly connected to the cup body and the cup mouth ring is pressed against the outwardly rolled pressure ring.

[0016] According to the above scheme, the present invention also includes a cup lid, which can be sealed on the cup mouth ring, and the cup lid is provided with a pull fastener and a tube insertion hole.

[0017] According to the above scheme, a gripping structure is provided on the outer wall of the cup body.

[0018] The beneficial effects of this utility model are as follows: This utility model has a reasonable structure. The neck sleeve connects the inner liner, the rubber sleeve and the cup body as a whole. The inner liner is detachable. After the inner liner is removed, water can be poured into the phase change cavity between the rubber sleeve and the inner liner. The frozen water causes the rubber sleeve to expand in the deformation cavity, which improves safety. You can get an iced drink by pouring the beverage into the inner liner. It is more flexible and convenient to use. Attached Figure Description

[0024] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-3 As shown, the present invention provides a pre-cooled iced beverage cup, comprising a cup body 1, a rubber sleeve 2, and an inner liner 3. The rubber sleeve 2 is installed inside the cup body 1, and the inner liner 3 is installed inside the rubber sleeve 2. A neck sleeve 4 is provided on the upper port of the cup body 1, which sequentially abuts and connects the upper port of the inner liner 3, the upper port of the rubber sleeve 2, and the upper port of the cup body 1. This forms a phase change cavity 31 between the inner liner 3 and the rubber sleeve 2, and a deformation cavity between the rubber sleeve 2 and the cup body 1. The phase change cavity 31 is used to fill with a phase change material. After freezing, beverages such as coffee or beer can be added to the inner liner 3 for chilling. Preferably, the inner liner 3, the rubber sleeve 2, and the cup body 1 are detachable and are nested together and fixed with the neck sleeve 4, allowing water to be used as the phase change material. In practical use, the inner liner 3 is first removed, an appropriate amount of water is added to the rubber sleeve 2, and then the inner liner 3 is inserted and fixed with the neck sleeve 4. After the entire unit is placed in a refrigeration unit and frozen for a period of time, the water expands, causing the rubber sleeve 2 to deform. The deformation cavity can offset the deformation of the rubber sleeve 2, thereby preventing the cup body 1 from breaking and making it safer to use.

[0026] Referring to the accompanying drawings, it can be understood that the cup body 1, the rubber sleeve 2, and the inner liner 3 are all hollow structures with openings at the top, allowing the upper ports of the three to be nested together and detachably fixedly connected by a neck sleeve 4, thereby forming the phase change cavity 31 and the deformation cavity between the three.

[0027] Specifically, the inner liner 3 is made of stainless steel, the sleeve 2 is made of silicone, and the cup body 1 is made of plastic. The stainless steel inner liner 3 has better thermal conductivity and strength, allowing for faster beverage chilling. The silicone sleeve 2 maintains the shape of the phase change chamber 31 after water is filled and prevents cracking during the freezing process. The material of the cup body 1 is not limited to plastic; a plastic cup body 1 can insulate against heat conduction, preventing frostbite and providing a better grip.

[0028] The deformation cavity includes a distortion groove 21. The bottom of the cup body 1 is provided with several transverse ribs 11, which form the distortion groove 21 at the bottom of the cup body 1. The bottom of the sleeve 2 can deform towards the distortion groove 21. The transverse ribs 11 are raised vertically and extend horizontally along the bottom of the cup body 1, allowing the bottom of the sleeve 2 to be supported by the transverse ribs 11, maintaining the shape stability of the sleeve 2 after water is poured into the phase change cavity 31. Furthermore, the intervals and gaps between the transverse ribs 11 form the distortion groove 21. As the water gradually freezes, the sleeve 2 can deform towards the distortion groove 21, preventing it from breaking the cup body 1.

[0029] The bottom of the rubber sleeve 2 is arched upwards. The rubber sleeve 2 is injection molded from silicone material. After the bottom surface of the rubber sleeve 2 is arched, it is far away from the bottom plate of the body 1, thereby providing more deformation range and preventing the rubber sleeve 2 from cracking after the water freezes.

[0030] The deformation cavity also includes an expansion cavity 22. The sleeve 2 has a draft angle H, thereby forming the expansion cavity 22 between the outer wall of the sleeve 2 and the inner wall of the cup body 1. It can be understood that the phase change cavity 31, in addition to the gap between the inner liner 3 and the bottom of the sleeve 2, also exists between the outer wall of the inner liner 3 and the inner wall of the sleeve 2. This part of the water will also expand after freezing, that is, the expansion of the side wall part of the sleeve 2 can fill the expansion cavity 22, preventing the cup body 1 from bursting.

[0031] Furthermore, as the ice in the phase change cavity 31 gradually melts, the rubber sleeve 2 gradually separates from the inner wall of the cup body 1, causing the expansion cavity 22 to reappear, which can extend the cooling and heat preservation time inside the cup body 1.

[0032] In simple terms, when the water in the phase change cavity 31 freezes, the rubber sleeve 2 will inevitably come into contact with the side wall of the cup body 1, causing the expansion cavity 22 to be filled. Of course, based on calculations and tests, a reasonable capacity for the expansion cavity 22 can be set to meet the expansion space required for the water in the phase change cavity 31 to freeze. Then, pouring a beverage into the inner liner 3 will cause the ice in the phase change cavity 31 to melt, and the rubber sleeve 2 will separate from the side wall of the cup body 1, causing the expansion cavity 22 to reappear. At this time, the expansion cavity 22 is equivalent to a partition space between the cup body 1 and the rubber sleeve 2, which can slow down and reduce heat conduction, thereby extending the chilling and heat preservation time inside the cup body 1.

[0033] The inner wall of the cup body 1 has a draft angle K, which is smaller than the draft angle H. The cup body 1 is molded from plastic material, and the draft angle K makes the cup body 1 easier to manufacture. It is understood that the draft angle K makes the inner diameter of the cup body 1 gradually decrease from top to bottom.

[0034] Furthermore, the draft angle K is smaller than the draft angle H, so that the gap between the outer wall of the sleeve 2 and the inner wall of the cup 1 gradually increases from top to bottom, thereby making the lower space of the expansion cavity 22 larger than the upper space, thus better eliminating the expansion factor caused by water freezing in the phase change cavity 31 and preventing the cup 1 from bursting.

[0035] The inner wall of the lower part of the cup body 1 is provided with several vertical stiffeners 12. These vertical stiffeners 12 and several horizontal stiffeners 11 are equidistantly spaced around the vertical central axis of the cup body 1, forming an L-shaped integrated structure. The lower part of the rubber sleeve 2 passes through the spaces between these vertical stiffeners 12. It is understood that after water is added to the phase change cavity 31, the rubber sleeve 2 will also undergo some deformation under gravity, and this deformation gradually increases from top to bottom. The vertical stiffeners 12 are equidistantly spaced around the vertical central axis of the cup body 1, forming a spaced ring at the lower part of the cup body 1, thereby limiting the deformation of the lower part of the rubber sleeve 2 and making the shape of the lower part of the rubber sleeve 2 more stable, thus ensuring the existence of the expansion cavity 22 between the upper outer wall of the rubber sleeve 2 and the cup body 1.

[0036] Furthermore, there are gaps between the vertical stiffeners 12, and the expansion cavity 22 also includes these gaps. The lateral expansion of the lower part of the rubber sleeve 2 can tend towards the gaps between the vertical stiffeners 12.

[0037] The upper port of the sleeve 2 has an outwardly flared flange 23, which fastens to the upper port of the cup body 1. The upper port of the inner liner 3 has an outwardly rolled pressure ring 32, which abuts against the outwardly flared flange 23. The neck sleeve 4 has a cup mouth ring 41, which is threaded to the cup body 1 and presses against the outwardly rolled pressure ring 32. The cup mouth ring 41, the outwardly rolled pressure ring 32, and the outwardly flared flange 23 are stacked sequentially from top to bottom on the upper port of the cup body 1. After the neck sleeve 4 is connected to the cup body 1, it forms a vertical assembly connection, allowing the inner liner 3, the sleeve 2, and the cup body 1 to be interconnected. It is understood that the neck sleeve 4 and the cup body 1 can be connected by a screw fastener or other conventional detachable connection method.

[0038] This invention also includes a cup lid 42, which is fitted onto the cup rim ring 41. The cup lid 42 has a pull-out fastener 43 and a straw insertion hole 44. This invention can be used to make iced mocha coffee. The cup lid 42 covers the cup rim ring 41, and drinking is more convenient after passing a straw through the straw insertion hole 44. Of course, when drinking beer or other beverages using this invention, the cup lid 42 can be omitted.

[0039] The outer wall of the cup body 1 is provided with a grip structure 13, which includes a handle and a non-slip sleeve. The entire invention will be frozen in the refrigeration equipment. The grip structure 13 can play the role of preventing slipping and blocking temperature conduction.

[0040] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
