Description

Technical Field

[0001] This utility model belongs to the field of portable drinking vessel technology, and in particular relates to an openable and closable coffee cup. Background Technology

[0002] Currently, most portable coffee cups on the market are designed for straw drinking, typically featuring a straw inlet and a vent on the lid to balance internal and external air pressure. Some existing products have lids that are designed for single-use only and cannot be resealed, making them susceptible to contamination during transport and lacking reusability. Another type of product uses a flip-top or rubber stopper sealing structure: flip-tops require lifting the lid to drink, while rubber stoppers require sealing the straw inlet and vent separately. These designs involve multiple steps, making quick one-handed opening and closing difficult, especially in situations requiring one-handed operation such as driving or commuting. Furthermore, if insufficient force is applied to ensure a complete seal when closing, leakage can easily occur if the cup is tilted or placed in a bag, contaminating personal belongings and affecting the user experience and hygiene. Utility Model Content

[0003] (I) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of this utility model is to provide an openable coffee cup to solve the technical problem that the lid of the existing portable coffee cup is difficult to achieve a quick and reliable seal under one-handed operation, which easily leads to liquid leakage when carrying it.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution provided in this application is as follows:

[0007] A closable coffee cup includes a cup body and a lid. The lid has a tube inlet, an air vent, and a sliding groove along a straight line. It also includes a sliding seal, which includes a first closing part, a second closing part, and a sliding part. The sliding part is disposed on the bottom surface of the lid and slides in cooperation with the lid. The first closing part is located on the top surface of the lid and its lower end is connected to the sliding part through the sliding groove. The first closing part is corresponding to the air vent. The second closing part is located on the bottom surface of the lid and is connected to the sliding part, and is corresponding to the tube inlet. Under the action of external force, the sliding seal slides along a straight line, opening and closing the air vent and the tube inlet respectively through the first closing part and the second closing part.

[0008] The sliding seal, as a single moving unit, controls the opening and closing of the vent and cannula simultaneously through linear sliding. During operation, the user only needs to push or pull the first cover in one direction to move the second cover at the bottom synchronously via the sliding part, achieving coordinated opening and closing of the two openings. This allows for simultaneous opening and closing of the cannula and vent with a single hand and a single step, greatly simplifying the usage process and improving ease of use and efficiency. Simultaneously, the sliding fit provides a stable alignment and pressing path for the sealing surface, achieving reliable sealing without excessive operating force. This structurally reduces the risk of leakage due to poor sealing, making it particularly suitable for use in mobile environments.

[0009] In some embodiments, the bottom surface of the cup lid is provided with first slide rails on both sides corresponding to the sliding part, which slide in cooperation with the sliding part.

[0010] The addition of the first slide rail significantly improves the directional stability and smoothness of the sliding seal during movement, effectively preventing it from shifting or jamming during sliding, thus improving the reliability of the seal. At the same time, the structure of the first slide rail also enhances the durability of the entire sliding mechanism and makes the operation feel smoother.

[0011] In some embodiments, the upper end of the first cover is recessed inward to form an elliptical structure.

[0012] The oval concave design increases the contact area of ​​the fingers, providing a natural point of force application, making single-finger push-pull operation more effortless and non-slip, significantly improving the user's comfort when pushing the first lid, further enhancing the convenience of single-handed operation of the product, and improving the user experience.

[0013] In some embodiments, the bottom surface of the cup lid protrudes outward within the sliding stroke range of the second cover portion to form a boss. The boss is penetrated by the insertion port and its lower end surface is a horizontal surface. The sliding seal also includes an arc-shaped connecting portion. One end of the arc-shaped connecting portion is connected to the sliding portion, and the other end is bent towards the boss and connected to the second cover portion.

[0014] The arc-shaped connector applies a clamping force perpendicular to the sealing surface to the second cover, ensuring a tight fit against the lower horizontal end face of the boss. This self-tightening effect enhances the sealing pressure on the cannula, compensates for manufacturing tolerances or minor wear, and achieves a more proactive and reliable sealing effect, effectively preventing liquid leakage from the main channel.

[0015] In some embodiments, two second slide rails are symmetrically formed on the protrusion at the position opposite the insertion port. The second slide rails slide in conjunction with the second cover portion, and the side of the second slide rail corresponding to the second cover portion is recessed inward to form an arc-shaped locking groove. An arc-shaped locking point is provided on the side of the second cover portion and embedded in the arc-shaped locking groove.

[0016] This locking mechanism provides clear tactile or audible feedback upon closure, allowing users to clearly perceive the sealing status. Furthermore, it features a mechanical interlock, effectively preventing accidental opening of the sliding seal due to impacts, vibrations, or compression within the bag. This significantly enhances safety and reliability during transport and completely avoids leakage accidents caused by accidental opening.

[0017] In some embodiments, the cup body has a double-layer insulation structure.

[0018] The double-layer insulation structure significantly enhances the cup's heat retention capacity, effectively delaying the temperature loss of beverages (such as coffee and tea) inside, allowing hot drinks to remain at a comfortable drinking temperature for a longer period, while cold drinks maintain their refreshing taste. Simultaneously, the air or vacuum layer between the outer and inner walls provides excellent insulation, preventing the outer surface temperature from becoming excessively high or low, thus preventing burns or frostbite to the user's hands while holding the cup, improving safety and comfort. Furthermore, this structure also enhances the cup's structural strength and durability, making the product more suitable for everyday carrying and various usage environments.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0026] This utility model provides an openable coffee cup, mainly comprising: a cup body 1 and a cup lid 2 detachably connected to the cup body 1. Specifically, the cup lid 2 has a tube inlet 201, an air vent 202, and a sliding groove 203 sequentially formed along the same straight direction. The core of this coffee cup is the provision of a sliding seal 3, which, as an integral component, includes a first fitting part 301, a second fitting part 302, and a sliding part 303 connecting the two. The sliding part 303 is located on the inner bottom surface of the cup lid 2, forming a sliding fit with the cup lid 2. The first fitting part 301 is located on the top surface of the cup lid 2, and its lower end passes through the sliding groove 203 on the cup lid 2 and is fixedly connected to the sliding part 303 below, and the position of the first fitting part 301 corresponds to the air vent 202. The second fitting part 302 is also located on the inner bottom surface of the cup lid 2, it is connected to the sliding part 303, and its position is set to correspond to the tube inlet 201. When the user applies external force to the first cover 301 with their finger, the entire sliding seal 3 can slide along a preset straight trajectory, thereby driving the first cover 301 to open or close the air hole 202, and simultaneously driving the second cover 302 to open or close the insertion port 201, realizing linkage control under single gesture operation.

[0027] Furthermore, to ensure the smooth and precise movement of the sliding seal 3, first slide rails 206 can be provided on both sides of the bottom surface of the cup lid 2 corresponding to the running path of the sliding part 303, and these first slide rails 206 are preferably integrally injection molded with the cup lid 2. They limit and guide the sliding part 303 from both sides, effectively preventing tilting or jamming during the sliding process. In this way, the linear movement trajectory of the sliding seal 3 is stably maintained, so that the first closing part 301 and the second closing part 302 can be accurately aligned with their respective openings each time, improving the reliability of the sealing action.

[0028] In some preferred embodiments, the upper end face of the first closing portion 301 located on the top surface of the cup lid 2 is designed as an inwardly concave elliptical structure. This concave shape conforms to the curvature of the fingertip, increasing the contact area and providing a natural point of force application. This not only makes single-finger push-pull operation more effortless and less slippery (due to the added anti-slip texture 3011), but also significantly improves the comfort of operation, optimizing the convenience of single-handed operation from an ergonomic perspective.

[0029] Building upon this, to enhance the sealing effect on the main liquid channel—the insertion port 201—an improved solution is proposed in this invention. Specifically, on the bottom surface of the cup lid 2, corresponding to the sliding stroke range of the second closing part 302, a boss 204 protrudes outward to form a boss 204. This boss 204 is penetrated by the insertion port 201, and its lower end face facing the inside of the cup is machined into a smooth horizontal sealing surface. Notably, the sliding seal 3 in this design adds an arc-shaped connecting part 304. One end of this arc-shaped connecting part 304 is connected to the sliding part 303, and the other end bends and extends towards the boss 204, finally connecting to the second closing part 302. The arc-shaped connecting part 304 itself is made of a material with a certain degree of elasticity, such as food-grade silicone or a tough engineering plastic. When the sliding seal 3 slides to the closed position, the arc-shaped connecting portion 304 undergoes slight elastic deformation, thereby continuously applying a pressing force perpendicular to the sealing surface of the boss 204 to the second cover portion 302, making the second cover portion 302 fit more tightly against the lower end face of the boss 204. This elastic self-tightening mechanism enhances the sealing pressure on the insertion port 201 and can compensate for minor manufacturing tolerances or wear, thereby achieving a more positive and reliable sealing effect.

[0030] Furthermore, to prevent the sliding seal 3 from accidentally opening due to accidental collision or compression during carrying, a mechanical locking mechanism can be added to the aforementioned boss 204 structure. A preferred embodiment is that two second slide rails 205 are symmetrically formed on both sides of the boss 204 opposite the insertion port 201. The second cover portion 302 slides in conjunction with the second slide rails 205 on both sides. Specifically, on the side of each second slide rail 205 facing the second cover portion 302, an arc-shaped locking groove 2051 is recessed inward; correspondingly, arc-shaped locking points 3021, which adapt to the shape of the arc-shaped locking groove 2051, are provided on both sides of the second cover portion 302. When the second cover portion 302 moves into position, the arc-shaped locking groove 2051 will engage, and the user will feel resistance, indicating that it is locked, providing clear tactile feedback. This device effectively prevents accidental opening due to external force inside the bag or during movement through mechanical interlocking, greatly improving the safety and reliability when carrying it.

[0031] Preferably, both the cup body 1 and the cup lid 2 can be made of food contact grade materials, such as engineering plastics that meet safety standards, such as polypropylene (PP) or Tritanium. TMCopolyester. The cup body 1 and the cup lid 2 can be detachably connected by means of threads, snaps, or interference fits, and a sealing ring is set at the interface to enhance the overall sealing performance. The sliding seal 3 can preferably be injection molded from a different material than the cup lid 2 to achieve specific functions by utilizing the material properties. For example, the cup lid 2 can be made of rigid PP to ensure structural strength, while the sliding seal 3 can be made of thermoplastic elastomer (TPE) to optimize sealing and feel.

[0032] Furthermore, to enhance the practicality and usability of the coffee cup, the cup body 1 of this application can adopt a double-layer insulation structure. Specifically, the cup body 1 consists of an inner wall and an outer wall, with a heat insulation layer formed between the inner and outer walls through a sealing technology. A preferred embodiment is to vacuum-insulate the cavity between the inner and outer walls to form a vacuum insulation layer; alternatively, the cavity can be filled with an insulation material such as polyurethane foam. The inner wall is typically made of food-grade stainless steel with good thermal conductivity to quickly respond to beverage temperatures, while the outer wall can be made of the same stainless steel or combined with low-density polypropylene plastic, ensuring both structural strength and ease of grip. In this way, this double-layer structure can significantly delay heat loss from hot beverages or cold beverages, maintaining a suitable temperature for a longer period. Simultaneously, the presence of the insulation layer makes the outer surface temperature of the cup body 1 closer to ambient temperature, effectively preventing burns or cold hands when the user holds it, thus improving safety and comfort. In addition, the double-layer structure enhances the overall impact resistance and durability of the cup body 1, making it more suitable for daily carrying and various usage scenarios.
