Description

Technical Field

[0001] This utility model relates to the field of cup technology, specifically a portable foldable water cup. Background Technology

[0002] With the improvement of people's living standards and the increasing demand for portability, collapsible water bottles have become widely popular due to their compact size and ease of carrying and storage. Existing collapsible water bottles typically feature a retractable folding section on their body, which is compressed to achieve the overall collapse of the bottle.

[0003] However, when modern cups are pulled up to expand their capacity, the cup's support relies entirely on the structural strength of the folding section. Common folding sections are often made of soft silicone or plastic, which have limited support. After being filled with liquid, especially under external pressure or internal negative pressure, the folding section is prone to unexpected collapse due to insufficient support, leading to a decrease in cup height or even internal liquid leakage, severely impacting user experience and reliability. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a portable foldable water cup that has the advantages of being foldable and having high support strength.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cup body and a cup lid, wherein the cup body is composed of a base, a lower cup body, a folding part and an upper cup body, wherein the lower cup body is fixed on the base, and the end wall of the lower cup body is connected to the interior of the upper cup body through the folding part; The outer periphery of the upper cup body is also fitted with a rotating ring and an abutting slider, and at least two abutting sliders are provided, wherein the abutting sliders extend inside the upper cup body.

[0006] Preferably, the bottom of the rotating ring rotates on the base, and a torsion spring is fixedly installed between the inner wall of the rotating ring and the inner wall of the lower cup body.

[0007] Preferably, the abutting sliders are evenly distributed circumferentially on the rotating ring, and the top of the abutting sliders is arranged in a multi-level stepped shape.

[0008] Preferably, the top of the abutting slider is arranged in a two-stage stepped shape, with the stepped surfaces being the first abutting surface and the second abutting surface.

[0009] Preferably, the upper cup body is the upper half of the cup body, and a cup lid is detachably installed on its top. The upper cup body is fitted onto the outer periphery of the lower cup body, that is, the radius of the upper cup body is greater than the radius of the lower cup body.

[0010] Preferably, the outer peripheral end face of the upper cup body is provided with at least two sliding grooves, the top of the sliding grooves is stepped, and the sliding grooves match the abutting slider.

[0011] Preferably, the folding part is the middle part of the cup body, and the lower cup body is the lower half of the cup body. One end of the folding part is fixed to the top of the lower cup body, and the other end is fixed to the side end face of the upper cup body, and is located in the middle part of the groove.

[0012] Preferably, the base, lower cup body, upper cup body, and cup lid are made of materials with the same hardness, and all of them have a harder hardness than the material of the folding part.

[0013] Compared with the prior art, the present invention provides a portable foldable water cup with the following advantages: 1. This portable foldable water bottle can increase the overall length of the cup by pulling the upper body upward. At this time, the torsion spring will cause the rotating ring and the abutting slider to rotate automatically, so that the abutting slider abuts against the bottom of the upper body. This can be used to support the upper body and effectively prevent the upper body from collapsing due to insufficient support of the folding part, which would cause the liquid inside the cup to leak.

[0014] 2. This portable foldable water bottle experiences varying degrees of deformation in its folding section due to the effects of hot and cold water, i.e., thermal expansion and contraction. When exposed to cold water, the folding section contracts, slightly shortening its overall height. In this case, the end face of the second contact surface abuts against the upper cup body, preventing excessive stretching of the folding section and permanent deformation that could affect its lifespan. When exposed to hot water, the folding section extends, slightly increasing its overall height. In this case, the end face of the first contact surface abuts against the upper cup body, preventing a gap between the contact slider and the upper cup body caused by thermal expansion. This gap provides a certain amount of allowance for the upper cup body to collapse in the event of collapse, thus preventing liquid leakage. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-6 As shown, the cup includes a cup body and a lid 30. The cup body is composed of a base 10, a lower cup body 11, a folding part 12, and an upper cup body 20. The lower cup body 11 is fixed to the base 10, and the end wall of the lower cup body 11 is connected to the interior of the upper cup body 20 through the folding part 12. The upper cup body 20 is the upper part of the cup body, and the lid 30 is detachably installed on its top. The upper cup body 20 fits around the outer periphery of the lower cup body 11, meaning that the radius of the upper cup body 20 is larger than the radius of the lower cup body 11, and the distance between them forms a space. This space allows the folding part 12 to... The upper cup body 20 has at least two grooves 201 on its outer peripheral side surface. The top of the groove 201 is stepped. The groove 201 matches the abutting slider 41. The folding part 12 is the middle part of the cup body, and the lower cup body 11 is the lower half of the cup body. One end of the folding part 12 is fixed to the top of the lower cup body 11, and the other end is fixed to the side surface of the upper cup body 20 and is located in the middle part of the groove 201. That is, the elongation of the cup body is the same as the length of the groove 201, and the height of the folding part 12 is half the elongation of the cup body.

[0019] The outer periphery of the upper cup body 20 is also fitted with a rotating ring 40 and an abutting slider 41. There are at least two abutting sliders 41, which extend inside the upper cup body 20. The bottom of the rotating ring 40 rotates on the base 10. There is a limiting structure (not shown in the figure) between the bottom of the rotating ring 40 and the base 10 to ensure that the rotating ring 40 rotates on the base 10 and will not detach from the base 10. A torsion spring 401 is fixedly installed between the inner wall of the rotating ring 40 and the inner wall of the lower cup body 11. The abutting sliders 41 are evenly distributed circumferentially on the rotating ring 40. The top of the abutting sliders 41 is set in a multi-level stepped shape. The multi-level stepped design can adapt to the length of the folded part 12 in various states after long-term use, ensuring that the abutting sliders 41 can always completely abut against the upper cup body 20 without gaps.

[0020] The top of the abutting slider 41 is set in a two-stage stepped shape, with the stepped surfaces being the first abutting surface 411 and the second abutting surface 412. This allows for different abutting surfaces to be selected when the inside of the cup contains hot or cold water, in order to accommodate the deformation allowance of the folded part 12 caused by thermal expansion and contraction.

[0021] The base 10, lower cup body 11, upper cup body 20, and lid 30 are all made of materials with the same hardness, and all of them have a harderness than the material of the folding part 12. That is, the other parts of the cup are made of plastic or iron, while the folding part 12 is made of food-grade silicone, which is flexible, resistant to bending, and has a certain degree of support after deformation, allowing the cup to be folded into different positions as needed. like Figure 1 As shown, the cup is in a folded state, with the folding part being fold section 12. Its overall storage volume is reduced by nearly half, significantly decreasing the overall size of the cup, making it easy to carry and not taking up much space. Figure 5 As shown, the cup is in its unfolded state, greatly increasing its overall storage volume for daily use.

[0022] When the cup body is unfolded, the torsion spring 401 is in a stored state, pulling the upper cup body 20 upward to increase the overall length of the cup body. At this time, under the elastic force of the torsion spring 401, the rotating ring 40 and the abutting slider 41 rotate automatically, so that the abutting slider 41 abuts against the bottom of the upper cup body 20, which can be used to support the upper cup body 20. This effectively prevents the upper cup body 20 from collapsing due to insufficient support of the folding part 12, which would cause the liquid inside the cup body to leak. Moreover, due to the influence of hot and cold water, the folding part 12 will undergo different degrees of deformation, that is, thermal expansion and contraction. That is, the folding part 12 is contracted when cold water is present. When the cup body 20 is in the extended state, the overall height of the folded part 12 will be slightly shortened. At this time, the cup body 20 is abutted by the end face of the second abutting surface 412, which can prevent the folded part 12 from being overstretched and causing permanent deformation, thus affecting its service life. When hot water is used, the folded part 12 is in the extended state, and the overall height will be slightly increased. At this time, the cup body 20 is abutted by the end face of the first abutting surface 411, which can prevent the abutting slider 41 from having a gap with the cup body 20 due to thermal expansion when it abuts. When the cup body 20 collapses, this gap will give the cup body 20 a certain collapse margin, thus preventing liquid leakage.

[0023] Working principle: When using the cup, if the cup body needs to be folded, first rotate the rotating ring 40 to store the torsion spring 401 until the abutting slider 41 is aligned with the slide groove 201. Then, press down on the upper cup body 20 to make the abutting slider 41 enter the slide groove 201. At this time, the folding part 12 deforms, so that the upper cup body 20 and the lower cup body 11 are in a folded state. The folding process is similar to that of modern folding basins.

[0024] When the cup needs to be unfolded, the upper cup body 20 can be pulled up directly, causing the folding part 12 to deform. The upper cup body 20 moves to the side away from the rotating ring 40. After it moves to the maximum distance, it just abuts against the slider 41 and disengages from the slide groove 201. Under the elastic force of the torsion spring 401, the abutting slider 41 rotates, thereby abutting against the bottom of the upper cup body 20 to support the upper cup body 20 and prevent the upper cup body 20 from collapsing naturally.

[0025] When the cup is filled with cold water, the folding part 12 will shrink due to cold. At this time, the second abutting surface 412 abuts against the bottom of the upper cup body 20, which can prevent the folding part 12 from stretching excessively. When the cup is filled with hot water, the folding part 12 will expand due to heat. At this time, the first abutting surface 411 abuts against the bottom of the upper cup body 20, which can prevent the upper cup body 20 from having a gap with the abutting slider 41, causing liquid leakage and the risk of scalding.

[0026] In summary, this portable foldable water bottle increases the overall length of the cup by pulling up the upper body 20. At this time, the torsion spring 401 causes the rotating ring 40 to rotate automatically, causing the abutment slider 41 to contact the bottom of the upper body 20. This supports the upper body 20 and effectively prevents it from collapsing due to insufficient support from the folding part 12, thus avoiding leakage of liquid inside the cup. The folding part 12 deforms to varying degrees due to the influence of hot and cold water, i.e., thermal expansion and contraction. Specifically, the folding part 12 is in a contracted state when exposed to cold water. The overall height of the folded part 12 will be slightly shortened. At this time, the end face of the second abutting surface 412 abuts against the upper cup body 20, which can prevent the folded part 12 from being overstretched and causing permanent deformation, thus affecting its service life. When hot water is used, the folded part 12 is in an extended state, and the overall height will increase slightly. At this time, the end face of the first abutting surface 411 abuts against the upper cup body 20, which can prevent the abutting slider 41 from having a gap with the upper cup body 20 due to thermal expansion when it abuts. When the upper cup body 20 collapses, this gap will give the upper cup body 20 a certain amount of collapse margin, causing liquid leakage.
