Description

Technical Field

[0001] The present application relates to the technical field of daily necessities, and in particular to a cup with a rotatable straw. Background Art

[0002] At present, with the improvement of people's quality of life, the requirements for the straw drinking experience of various daily beverages are getting higher and higher, and convenient and fast drinking methods are becoming more and more important. As an auxiliary tool for beverage consumption, the design and function of straws directly affect the consumer's experience.

[0003] However, existing straw designs present several issues, such as the ease with which straws are lost, difficulty in sipping viscous beverages, and the need to stir solid-liquid suspensions. For example, when sipping common beverages on the market, such as low-viscosity fluids (e.g., milk), drinks with a certain viscosity (e.g., yogurt), and solid-liquid suspensions (e.g., orange juice with fruit pieces), users often encounter issues such as emptying the straw, high viscosity residue, the need for stirring, and lost straws.

[0004] Specifically, when using a traditional straw to drink low-viscosity fluids like milk, the angle between the straw and the bottle often needs to be constantly adjusted, making it difficult to empty the drink. For highly viscous materials like yogurt, users report that it's very easy for a large amount of drink to remain on the wall of the cup or the inner wall of the Tetra Pak. Not only does the angle of the straw need to be adjusted, but the height also requires squeezing the package, which can result in incomplete drinking. Some even require cutting open the package and using a spoon to consume. When drinking solid-liquid suspension drinks like Orange Juice, users need to shake the drink to get a relatively homogeneous consistency, which is inconvenient. Utility Model Content

[0027] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0029] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0030] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0031] In a preferred embodiment, see Figures 1 to 5 The present application provides a cup 1 with a rotatable straw, comprising: a cup body 10, a cup lid 20 and a straw assembly 30. The cup body 10 includes a cavity 11, the cup body 10 is connected to the cup lid 20, one end of the straw assembly 30 is placed in the cavity 11, and the other end passes through the cup lid 20 and is rotatably connected to the cup lid 20; the straw assembly 30 comprises: a tube body 31, the tube body 31 is rotatably connected to the cup lid 20, and a scraper structure 33 is provided at one end of the tube body 31 placed in the cavity 11; a sliding sleeve 32, the sliding sleeve 32 is sleeved on the tube body 31, and the sliding sleeve 32 is placed at the end of the tube body 31 extending out of the cup lid 20; wherein, by pulling or pressing the sliding sleeve 32, the tube body 31 can drive the scraper structure 33 in the cavity 11 to rotate up or down.

[0032] As a preferred option, see Figure 4 A first side suction port 311 is provided on the side wall of the tube body 31 . The first side suction port 311 is located at one end of the tube body 31 that is positioned in the cavity 11 .

[0033] As another preferred embodiment, the tube body 31 includes two ports that are relatively through-connected, wherein the two ports are a liquid inlet port 312 and a liquid outlet port 313. The liquid outlet port 313 is the port for the user to suck liquid using the tube body 31. The liquid inlet port 312 of the two ports is located in the cavity 11, and the liquid outlet port 313 extends out of the cup cover 20. The first side suction port 311 is connected to the hole wall of the liquid inlet port 312. When the tube body 31 is inserted into the bottom end of the cavity 11 and abuts against the bottom wall, the liquid in the cavity 11 cannot enter through the liquid inlet port 312 opened by the tube body 31. At this time, the liquid in the cavity can be sucked into the tube body 31 from the position of the first side suction port 311 to assist the liquid inlet port 312.

[0034] For further optimization, see Figure 4 The scraper structure 33 includes: a side suction pipe 331, which is fixedly connected to the side wall of the tube body 31 and communicates with the tube body 31; and a scraper body 332, which is fixedly connected to the side wall of the side suction pipe 331.

[0035] More preferably, a second side suction port 334 is formed at one end of the side suction pipe 331 away from the pipe body 31 , and the side suction pipe 331 includes a liquid inlet opening 333 , and the second side suction port 334 is communicated with the hole wall of the liquid inlet opening 333 .

[0036] Preferably, the side suction tube 331 and the scraper body 332 are arranged in contact with the inner wall of the cavity 11. At the same time, the plate surface of the scraper body 332 and the hole wall of the second side suction port 334 are smoothly transitioned, so that the liquid can flow directly from the scraper body 332 into the second side suction port 334, making it convenient for users to suck.

[0037] Preferably, the side suction pipe 331 is arranged obliquely relative to the pipe body 31 , and the scraper body 332 is arranged spirally obliquely relative to the side suction pipe 331 .

[0038] It should be noted that in this application document, three side straws 331 are preferably distributed along the periphery of the tube body 31. Correspondingly, the three side straws 331 are respectively connected to three scraper bodies 332. The side straws 331 are tilted and can extend to the corners at the bottom of the cavity 11 in the cup body 10, thereby satisfying the requirement in this application document that the cup can suck the beverage at the bottom of the cavity 11 at all angles. At the same time, for the beverage residue on the inner wall of the cavity 11, this application document realizes the spiral rise or fall of the straw assembly 30 by the user holding the sliding sleeve 32 to pull up or press down the tube body 31.

[0039] More preferably, the tube body 31 is connected to the cup cover 20 by threads. Figure 1 and Figure 2 The sliding sleeve 32 is sleeved around the outer edge of the tube body 31 and secured to a single location on the outer wall of the tube body 31 via a protruding flange on the outer wall of the tube body 31, preventing the sliding sleeve 32 from moving up and down relative to the tube body 31. When using the cup 1 with a rotatable straw disclosed herein, the user simply grasps the sliding sleeve 32 and pulls up the tube body 31. The tube body 31, threadedly connected to the cup lid 20, then rotates and rises relative to the sliding sleeve 32. Similarly, when the user presses down on the sliding sleeve 32, the tube body 31 rotates and descends relative to the sliding sleeve 32. As the tube body 31 is lifted, it spirals upward, causing the three scraper bodies 332, which are attached to the inner wall of the bottle, to spiral upward accordingly, collecting the beverage at the bottom of the inclined scraper bodies 332 for suction by the side straw 331. Furthermore, the scraper bodies 332 also rotate back and forth as the tube body 31 reciprocates, thereby stirring the beverage.

[0040] And preferably, the pitch a of the thread is limited to 2n times the thread diameter r. Specifically, in actual use, the outer wall of the tube body 31 is provided with an external thread 50, and correspondingly, the cup cover 20 is provided with an internal thread 40. The thread lead angle of the external thread 50 will affect the self-locking of the tube body 31 relative to the cup cover 20, and the thread self-locking angle refers to the condition under which the thread can self-lock when the thread lead angle is less than or equal to the friction angle. The thread lead angle is the angle between the thread axis and the side surface of the thread, and the friction angle is the angle between the normal reaction force and the supporting force when the static friction force reaches its maximum value. In engineering practice, the thread lead angle usually needs to be smaller than the friction angle to achieve self-locking. Therefore, through multiple groups of experiments in this application document, it is preferred to select the pitch a to be set to 2 times the thread diameter r, so as to avoid self-locking of the tube body 31 relative to the cup cover 20. At the same time, due to the increase in pitch a, the effective length of the internal thread 40 in the cup cover 20 will be insufficient, and the lifting tube body 31 cannot be effectively rotated. Therefore, the number of thread heads is further increased in this application, that is, preferably, the external thread 50 in this application document is set as a two-start thread, which not only meets the requirement that the thread lead angle is greater than the self-locking angle, but also realizes sufficient thread engagement section, ensuring that the tube body 31 can drive the scraper structure 33 to spiral up or down smoothly.

[0041] The cup with a rotatable straw in this application can effectively solve the problems of incomplete drinking and lost straw, thereby improving the consumer's drinking experience. The design of the straw assembly 30 not only improves the efficiency of drinking, but also reduces beverage residue and avoids the problem of lost straw.

[0042] In another embodiment, participating Figure 6 , the straw assembly 30 can also be equipped with integrated intelligent temperature control to provide a more user-friendly experience. For example, a temperature control element 60, specifically a small temperature-controlling ball, is installed within the tube body 31. This element utilizes differences in thermal expansion rates between materials to intelligently control the straw channel, preventing overheated or overcooled beverages from being drawn up, providing a safer and more comfortable drinking experience. Furthermore, considering environmentally friendly and cost-effective material selection, biodegradable materials such as PLA (polylactic acid) and PHA (polyhydroxyalkanoate) are selected to ensure product sustainability.

[0043] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
