Description

Technical Field

[0001] This invention relates to a lid for a drinking device, and more particularly to a straw cup and its lid. Background Technology

[0002] To maintain health, people must consume a certain amount of water daily, and drinking liquids is the primary means of hydration. With rising living standards, people have increasingly higher demands for beverage taste, leading to the adoption of various methods to improve it. Currently, the main method for improving beverage taste involves adding additives to water, typically through extraction or dissolution. Examples include steeping tea leaves in water, or preparing additives as solid beverages or pre-mixing them into bottled drinks. However, these commonly used methods have certain drawbacks. Extraction methods generally require hot water and separating the tea leaves and other flavorings, making the process cumbersome. Dissolution methods often involve additives that can be harmful to health and can easily lead to excessive energy intake for consumers.

[0003] To solve the above technical problems, it is necessary to develop a water cup that is easy to use and can adjust the flavor of beverages simply by drinking plain water. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a water cup and its lid that can adjust the flavor of beverages without pre-extracting or dissolving additives.

[0005] The technical problem further solved by the present invention is to provide a water cup and its lid that are simple in structure, easy to replace additives, and can adjust the flavor of beverages without pre-extracting or dissolving additives.

[0006] The technical solution to achieve the objective of this invention is:

[0007] A cup lid includes a body, a lid body, a straw, and a spice box; the lid body is connected to the body and has at least two states: open and closed; the straw is disposed through the body and has an aroma guide hole that communicates with the outside on its outer circumference; the spice box is disposed on the body, and the inner cavity of the spice box contains spices, and the spice box also has an aroma guide hole that communicates with the inside; the spice box has at least two states that are linked with the lid body: when the lid body is open, the aroma guide hole communicates with the aroma guide hole on the straw; when the lid body is closed, the aroma guide hole is offset from the aroma guide hole on the straw.

[0008] The key features of this invention are: by providing an aroma guide hole that connects the inside and outside of the straw's outer circumference and an aroma outlet on the straw, users can experience the feeling of drinking a beverage even when drinking plain water; on the other hand, the aroma box can be carried with the cup lid and does not need to be stored separately, making it more convenient to use compared to traditional water cups; furthermore, since the aroma box is stored separately from the water, there is no need to use additives to improve the taste of the beverage, which can avoid users ingesting additives and is more beneficial to their health.

[0009] Furthermore, the main body is provided with a groove, and the straw and the spice box are both disposed in the groove, with at least one side of the spice box in contact with the straw; the fragrance guide hole and the fragrance hole are respectively provided on the contact surfaces of the straw and the spice box.

[0010] When the lid is closed, the straw and spice box can be stored in the groove, making the overall structure of the lid more compact. The straw and spice box are respectively provided with overflow guide holes and overflow holes on their mating surfaces, which can form an effective spice channel to ensure that the spices can be mixed with water smoothly after passing through the spice channel.

[0011] The spice box can be set up independently. Simply change the flavor of the spices filled in the spice box to quickly replace the spice box, making it more convenient to use.

[0012] Furthermore, the cup lid also includes an elastic element located in a groove within the main body; the elastic element is an independent structure or integrated with the main body, the straw, or the spice box; the lid body is provided with a pressing block; when the lid body is opened, the elastic element provides elastic force to the spice box, connecting the aroma outlet hole with the aroma guide hole on the straw; when the lid body is closed, the pressing block presses against the spice box, causing the spice box to overcome the elastic force provided by the elastic element, thereby causing the aroma outlet hole to be misaligned with the aroma guide hole on the straw.

[0013] The cleverly designed elastic element makes the pressing block feel softer and more comfortable to use when pressed into the spice box. The control spring controls the connection between the fragrance overflow hole and the fragrance guide hole, making the connection between the two more stable and eliminating the need to manually determine the connection, making it more convenient and faster to use.

[0014] Furthermore, the upper surface of the spice box is provided with a vent hole corresponding to the position of the pressure block. The vent hole ensures unobstructed gas flow inside the spice box, thereby ensuring that the aroma can overflow from the fragrance outlet. At the same time, since the position of the vent hole corresponds to the position of the pressure block, when the lid is closed, the pressure block can seal the vent hole, thereby ensuring the durability of the spice in the spice box.

[0015] Furthermore, the main body is provided with vent holes, and the lid is provided with a sealing block; when the lid is closed, the sealing block seals the vent holes on the main body. The vent hole design on the main body allows the internal and external pressure difference to remain at a normal level; the sealing block design on the lid allows the lid to achieve an effective seal, ensuring that there is no spillage or leakage when there is water in the cup.

[0016] Furthermore, the pressure block and sealing block of the cover are an integral structure. This allows for one-button control of the pressure block and sealing block, making operation more convenient and faster, while reducing assembly steps.

[0017] Furthermore, both the pressure block and the sealing block of the lid are made of elastic material. When the lid is closed, the elastic material deforms, making the connection between the pressure block and the spice box, and between the sealing block and the vent on the body, more tight and providing better sealing. Moreover, when the cup is subjected to a violent impact, it can ensure that the spice box does not deform and that the gap between the vent and the sealing block does not change drastically, preventing liquid leakage.

[0018] Furthermore, the inner end of the fragrance guide hole on the straw is lower than the outer end. This design allows the center line of the fragrance guide hole on the mouthpiece to be tilted between 0° and 90° with the center line of the mouthpiece, preventing residual water in the straw from flowing back into the fragrance box and causing damage to the fragrance box.

[0019] Furthermore, the cross-sectional area of ​​the fragrance guide hole on the straw gradually increases from the inside to the outside. During use, the fragrance enters the water through the interconnected fragrance holes and guide holes for mixing. During transport, the channel narrows, increasing the flow rate and accelerating the mixing speed between the fragrance and water, resulting in a more uniform mixture.

[0020] Furthermore, the spice box has a notch surrounding the straw at one end near the straw, and the fragrance overflow hole is located on the inner sidewall of the notch. This notch design allows the spice box and the straw to fit tightly together, preventing fragrance leakage due to insufficient airtightness between the fragrance overflow hole and the fragrance overflow guide hole on the straw; it also restricts the movement of the spice box and serves to fix it in place.

[0021] Furthermore, the spice box has symmetrical arc-shaped protrusions on both sides of the end away from the straw; the groove of the main body has arc-shaped recesses that cooperate with the arc-shaped protrusions. This design allows the spice box to rotate within the groove of the main body while preventing it from easily falling out of the groove, and it is also very convenient to install and disassemble.

[0022] Furthermore, the rear end of the lid is rotatably connected to the rear end of the main body, and the front end of the lid is connected to the main body via a latch. In use, simply open the latch; there is no need to remove the lid, thus avoiding contamination from contact with other items after removal or loss due to user negligence.

[0023] Furthermore, the rear end of the main body is provided with a rotating part, and a rotating shaft is horizontally inserted through the rotating part; the rear end of the lid extends downward with two spaced rotating ears, which are rotatably connected to the two ends of the rotating shaft respectively. The symmetrical rotating ear design makes the force on both ends of the rotating shaft more even, extending the life of the rotating part between the main body and the lid.

[0024] Furthermore, the rotating part of the main body includes a rotating seat, a torsion spring, and a torsion spring cover; the rotating seat is integrally disposed at the upper rear part of the main body, and a receiving cavity is provided on one side of the rotating seat. One side of the torsion spring cover extends into the receiving cavity of the rotating seat and is rotatably connected to the rotating seat; the rotating shaft passes through the rotating seat and the torsion spring cover; the torsion spring is disposed in the receiving cavity of the rotating seat and connects the rotating seat and the torsion spring cover; an upper arc-shaped protrusion is provided on the outer circumferential surface of the other side of the torsion spring cover; a lower arc-shaped protrusion is provided on the inner side of one of the rotating ears of the main body; the upper arc-shaped protrusion of the torsion spring cover overlaps the lower arc-shaped protrusion of the rotating ear.

[0025] The torsion spring structure connects the rotating base and the torsion spring cover, which can effectively maintain the opening and closing state of the cup lid; the semi-enclosed design of the rotating part can effectively avoid oxidation caused by direct contact between the torsion spring and the air, thus extending the service life of the rotating part.

[0026] Furthermore, the latch includes a locking button, a locking torsion shaft, a spring, and a locking button; a locking torsion groove is provided on the front end face of the body; the locking torsion shaft is horizontally inserted through both sides of the locking torsion groove; the locking button is located in the locking torsion groove, and the middle part of the locking button is rotatably connected to the locking torsion shaft; a lower hook is provided on the upper part of the locking button, and an upper hook suitable for cooperating with the lower hook is provided on the front end of the cover; the spring is located between the lower part of the locking button and the locking torsion groove; the locking button is U-shaped, the locking button is located outside the locking torsion groove, and the two ends of the locking button are rotatably connected to the two ends of the locking torsion shaft respectively.

[0027] The upper and lower halves of the locking knob form a lever structure that can rotate along the locking torsion axis. When the lid is closed, the spring is compressed, and the part of the locking knob located below the locking torsion axis springs outward, so that the lower hook and the upper hook are tightly engaged and maintain their engagement state, making the lid close more stably and preventing the lid from opening automatically in the event of a collision or other abnormal use, thus preventing water from spilling out of the cup.

[0028] Furthermore, the aforementioned cup lid can be applied to a straw cup, which includes a cup lid and a cup body, and the structure of the cup lid is consistent with the cup lid structure described above.

[0029] By adopting the above technical solution, the present invention has the following beneficial effects:

[0030] (1) The present invention provides a fragrance guide hole that connects the inside and outside of the outer periphery of the straw and a fragrance hole on the straw, so that users can feel like they are drinking a beverage when drinking plain water. On the other hand, the fragrance box can be carried with the cup lid and does not need to be stored separately, which is more convenient to use than a traditional water cup. Furthermore, since the fragrance box is stored separately from the water, there is no need to use additives to improve the taste of the beverage, which can avoid users from ingesting additives and is more beneficial to their health.

[0031] (2) The present invention has a groove on the cup lid body and adopts a storage design for the straw and spice box, resulting in a compact overall structure and smaller size.

[0032] (3) The present invention uses an elastic element to control the connection state between the fragrance overflow hole and the fragrance guide hole, which makes the feel softer and the connection state between the fragrance overflow hole and the fragrance guide hole more stable. There is no need to manually determine the connection state between the two, making it more convenient and faster to use.

[0033] (4) The present invention has designed vent holes on the cup lid body, which can maintain the normal internal and external pressure difference and effectively seal the lid body to prevent liquid from spilling or leaking.

[0034] (5) The cover pressing block and sealing block designed in this invention are an integrated structure, and the pressing block and sealing block can be controlled with one button, making the operation more convenient and faster.

[0035] (6) The lid pressing block and sealing block of the present invention are both made of elastic material. By utilizing the deformation characteristics of elastic material, the combination between the pressing block and the spice box and the sealing block and the vent hole on the body is more tight. Moreover, when the cup is subjected to violent impact, it can ensure that the spice box does not deform and the gap between the vent hole and the sealing block does not change drastically, thus preventing liquid leakage.

[0036] (7) The height difference between the inner and outer ends of the fragrance guide hole on the straw of the present invention avoids the backflow of residual water in the straw and protects the fragrance box.

[0037] (8) The cross-section of the fragrance guide hole on the straw of the present invention is designed to be from large to small. By utilizing Bernoulli's principle, the flow rate of the fragrance in the channel gradually increases, the mixing speed between the fragrance and water becomes faster, and the mixing becomes more uniform.

[0038] (9) The present invention uses a U-shaped notch at the end of the spice box near the straw to achieve a tight fit between the straws, which improves the airtightness and effectively fixes the position of the spice box, making its structure more stable.

[0039] (10) The present invention adopts a convex and concave design for the spice box and the cup lid body, and the bottom of the concave is smoother and easier to clean.

[0040] (11) The rear end of the lid of the present invention is rotatably connected to the body, and the front end of the lid is connected to the body by a latch. It can be operated with one hand during use, and avoids contamination caused by contact with other items after the lid is removed or loss of the lid due to user negligence.

[0041] (12) The present invention adopts a symmetrical rotating ear and rotating shaft connection between the cover and the body, which makes the contact point more uniformly stressed and effectively extends the life of the rotating part.

[0042] (13) The present invention provides a torsion spring structure for the rotating part, which can effectively maintain the opening and closing state of the cup lid. The semi-enclosed design of the torsion spring can effectively avoid oxidation caused by direct contact between the torsion spring and the air, thus extending the service life of the rotating part.

[0043] (14) The upper and lower hooks of the locking part connecting the cup lid and the body of the present invention are engaged, and the lever structure and spring are used to maintain the locking engagement state, making the cup lid more stable when closed, and preventing the lid from automatically opening in the event of a collision or other abnormal use, causing the water in the cup to spill out.

The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and should not be used to limit the scope of protection of the present invention.

[0070] Figures 1 to 9 The image shows an embodiment of the present invention. This embodiment relates to a straw cup, which includes a lid and a body 7.

[0071] The cup lid includes a body 1, a lid 2, a straw 3, and a spice box 4. The lid 2 is connected to the body 1. The straw 3 is inserted through the body 1, and its outer circumference has an inward and outward connecting aroma guide hole 3-1. The spice box 4 is located on the body 1. The inner cavity of the spice box 4 contains spices, and the spice box 4 also has an inward and outward connecting aroma guide hole 401-1.

[0072] In this design, the lid has at least two states: open and closed. Correspondingly, the spice box 4 has at least two states that are linked with the lid 2: when the lid 2 is open, the spice outlet 401-1 is connected to the spice guide hole 3-1 on the straw 3; when the lid 2 is closed, the spice outlet 401-1 is offset from the spice guide hole 3-1 on the straw 3.

[0073] In use, the aroma outlet 401-1 and the aroma guide outlet 3-1 are interconnected to form an aroma channel. The aroma enters the mouth directly after passing through the aroma channel and is mixed. It can produce a beverage taste without the need for additives, making it very convenient to use.

[0074] The main body 1 is provided with a groove 1-1; the straw 3 and the spice box 4 are both set in the groove 1-1, and at least one side of the spice box 4 is in contact with the straw 3; the straw 3 and the spice box 4 are respectively provided with an overflow guide hole 3-1 and an overflow hole 401-1 on the contact surface.

[0075] When the lid is closed, the straw 3 is pressed into the groove 1-1 and stored in the groove 1-1 together with the spice box 4; when the lid is opened, the straw 3 pops out, and the fragrance guide hole 3-1 of the spice box 4 is connected to the fragrance hole 401-1 of the straw 3, keeping the fragrance channel unobstructed.

[0076] An elastic element 5 is provided in the groove 1-1 of the body 1 of the cup lid. The elastic element 5 is an independent structure, or it is integrated with the body 1, the straw 3, or the spice box 4. A pressure block 2-1 is provided on the lid 2. When the lid 2 is opened, the elastic element 5 is released from pressure and rebounds, the spice box 4 moves upward, and the aroma overflow hole 401-1 connects with the aroma overflow guide hole 3-1 on the straw 3. When the lid 2 is closed, the pressure block 2-1 presses against the spice box 4, the elastic element 5 is compressed, and the spice box 4 is subjected to forces from the elastic element 5 and the pressure block 2-1 respectively. The aroma overflow hole 401-1 is misaligned with the aroma overflow guide hole 3-1 on the straw 3 and remains misaligned. The upper end face of the spice box 4 is provided with a vent hole 401-5 corresponding to the position of the pressure block 2-1. The vent hole 401-5 can ensure the smooth flow of gas inside the spice box, thereby ensuring that the aroma can overflow from the aroma overflow hole 401-1. Meanwhile, since the position of the vent 401-5 corresponds to the position of the pressure block 2-1, when the cover 2 is closed, the pressure block 2-1 can seal the vent 401-5, thereby ensuring the durability of the fragrance in the fragrance box 4.

[0077] The body 1 of the cup lid is also provided with vent holes 1-2, through which air can enter the cup and eliminate the pressure difference caused by the reduction of liquid. At this time, the straw can work normally.

[0078] The lid 2 is provided with a sealing block 2-2. When the lid 2 is closed, the sealing block 2-2 seals the vent hole 1-2 on the body 1. At this time, the liquid is sealed inside the cup 7. When the cup 7 is not placed horizontally, there will be no spillage or leakage.

[0079] The pressure block 2-1 and sealing block 2-2 of the lid body 2 are an integral structure. Pressing down the pressure block 2-1 will cause the aroma overflow hole 401-1 of the spice box 4 to move downward. At this time, the aroma overflow hole 401-1 is misaligned with the aroma overflow guide hole 3-1 on the straw 3, and the spice is confined in the spice box 4 and will not escape. At the same time, the sealing block 2-2 and the vent hole 1-2 are in a closed state, and the water in the cup is sealed.

[0080] The pressure block 2-1 and sealing block 2-2 of the lid body 2 are both made of elastic material. When the lid body 2 is closed, the elastic material is compressed and deformed. The pressure block 2-1 presses against the spice box 4 without a rigid impact, resulting in a gentler feel. The sealing block 2-2 seals the vent hole 1-2 on the sealing body 1, and the gap at the contact point is filled with elastic material. The seal block 2-2 and the vent hole 1-2 on the body are more tightly bonded, preventing liquid from leaking out of the cup body 7. When the cup body 7 is subjected to a violent impact, the spice box 4 is subjected to the relative force of the elastic element 5 and the elastic material of the sealing block 2-2. Its positional change is relatively gentle, avoiding severe deformation.

[0081] The inner end of the fragrance guide hole 3-1 on the straw 3 is lower than the outer end. At this time, the center line of the fragrance guide hole 3-1 on the mouthpiece 3 is inclined between 0° and 90° with the center line of the mouthpiece 3. The end of the mouthpiece 3 that is closer to the fragrance box is higher than the water surface. The water remaining in the straw 3 cannot flow back into the fragrance box 4, causing damage to the fragrance box 4.

[0082] The cross-sectional area of ​​the fragrance guide hole 3-1 on the straw 3 gradually increases from the inside to the outside. When the fragrance passes through the fragrance channel, the fragrance channel becomes smaller and its flow rate gradually increases. It obtains the maximum flow rate at the outlet. Compared with the fragrance channel with a constant cross-section, its mixing speed is faster.

[0083] A notch surrounding the straw 3 is provided at one end of the spice box 4 near the straw 3, and an overflow hole 401-1 is located on the inner side wall of the notch. This notch design allows the spice box 4 and the straw 3 to fit tightly together, preventing spice leakage due to insufficient airtightness between the overflow hole 401-1 and the overflow guide hole 3-1 on the straw; it also restricts the movement of the spice box 4 and serves to fix it in place.

[0084] The spice box 4 has symmetrical arc-shaped protrusions 401-4 on both sides of the end away from the straw 3; the groove 1-1 of the body 1 has an arc-shaped recess 1-1-1 that matches the arc-shaped protrusions 401-4. The design of the arc-shaped protrusions 401-4 and the arc-shaped recess 1-1-1 allows the spice box 4 to rotate within the groove 1-1 of the body, while preventing the spice box 4 from easily falling out of the groove 1-1 of the body, and also makes installation and disassembly very convenient.

[0085] The specific structure of the aforementioned spice box 4 is as follows:

[0086] The device includes a shell 401, a fragrance pack 402, a fragrance absorber 403, and a squeezing needle 404. The fragrance pack 402 and the fragrance absorber 403 are disposed inside the shell 401. The shell 401 has a fragrance overflow hole 401-1 that extends through the inside and outside. The fragrance pack 402 includes a packaging film and a fragrance contained within the packaging film. The shell 401 has a through hole 401-2 on the side near the fragrance absorber 403 and away from the fragrance pack 402. The squeezing needle 404 is disposed in the through hole 401-2 of the shell 401 and penetrates the fragrance absorber 403. The end of the squeezing needle 404 facing the fragrance pack 404 has a pointed tip 404-1. The squeezing needle 404 has two states: packaging and use. In the packaging state, the pointed tip 404-1 of the squeezing needle 404 does not contact the fragrance pack 402. In the use state, the squeezing needle 404 punctures the packaging film of the fragrance pack 402.

[0087] It should be noted that any material that can separate the fragrance from the fragrance adsorbent 403 can be used to package the fragrance. For example, when the fragrance particles are in the form of a powder with very small particles, a filter membrane with micropores can be used as the packaging material.

[0088] The fragrance adsorbent 403 is not a necessary accessory for the fragrance box. In certain situations, such as when service life is not required, the fragrance itself is volatile, there is no possibility of leakage of the fragrance in the fragrance box, or the packaging film of the fragrance pack 402 itself has certain adsorption properties, the fragrance adsorbent 403 can be used to achieve a slow-release effect without setting up the fragrance adsorbent 403.

[0089] For the setting of the fragrance adsorbent 403 and the squeezing needle 404, it is only necessary to ensure that the fragrance pack 402, the fragrance adsorbent 403 and the squeezing needle 404 are placed in sequence. The squeezing needle 404 can be set in other positions of the fragrance box, such as on one side of the fragrance box, and other methods can be used to control the squeezing needle 404 to puncture the fragrance box.

[0090] The spice pack 402, the spice absorber 403, and the squeezing needle 404 are placed in sequence, so that the squeezing needle 404 can pierce the spice pack 402 through the spice absorber 403, leaving only one spice outlet on the spice pack 402, and controlling the spice to flow out slowly.

[0091] When rapid fragrance flow is required, the squeezing needles 404 can be designed as a set mounted on a fixed device. When the squeezing needles 404 puncture the fragrance pack 402, multiple fragrance outlets can be generated, and the fragrance flow rate is accelerated.

[0092] The state of the fragrance packet 402 can be controlled by controlling the state of the squeezing needle. Before use, the tip 404-1 of the squeezing needle 404 should be kept away from contact with the fragrance packet 402 to avoid damage to the fragrance packet 402.

[0093] The front end of the outer shell 401 of the spice box 4 is provided with a notch, and the aroma overflow hole 401-1 is provided on the inner side wall of the notch. After the spice box is installed in the lid of the water cup, the notch can fit tightly with the straw, and the aroma can be emitted from the aroma overflow hole 401-1. In order to accelerate the aroma overflow speed, multiple aroma overflow holes can be provided on the inner side wall of the notch.

[0094] When the spice box 4 is installed in the cup lid, the notch restricts the movement of the spice box 4, thus providing a good fixation effect.

[0095] It is worth noting that the design of the contact surface is to maintain the airtightness of the fragrance outlet 401-1. If the contact surface between the fragrance box and the water cup straw is not curved but flat, then this notch is not necessary and should be set as a flat surface that fits with the straw.

[0096] The through hole 401-2 of the outer shell 401 is provided on the bottom surface of the outer shell 401, the fragrance adsorbent 403 is located at the inner bottom of the outer shell 401, and the fragrance pack 402 is located above the fragrance adsorbent 403.

[0097] When the squeezing needle 404 punctures the fragrance pack 402, the fragrance overflows from the puncture in the fragrance pack 402 due to gravity and falls onto the fragrance adsorbent 403. The fragrance adsorbent 403 can adsorb the fragrance and prevent it from overflowing further.

[0098] If the fragrance itself is unlikely to leak out, or if the packaging film of the fragrance packet 402 itself has an absorption function, then there is no need to install the fragrance adsorption component 403.

[0099] The upper end face of the outer casing 401 is provided with a handle 401-3, and the handle of the outer casing 401 is provided with a first anti-slip texture 401-3-1.

[0100] The anti-slip texture is designed to increase the force between the user's fingers and the handle 401-3, making it easier to use. Therefore, there are several alternatives, such as grooves, protrusions, or recesses.

[0101] To install or remove the spice box, unscrew the handle 401-3 and insert or remove the lid. The anti-slip texture is designed to increase friction, so that the spice box doesn't need to be squeezed tightly when unscrewing. If the material used to make the spice box has a sufficiently high coefficient of friction, the anti-slip texture may not be necessary.

[0102] The handle 401-3 is designed to facilitate opening the spice box lid and replacing the spice box. However, other methods can be used instead. For example, a groove can be provided on the side or surface of the spice box lid, allowing the user to place their fingernail or other tools into the groove and use it as a point of contact to open the spice box lid.

[0103] The sides of the spice box can be designed as straight lines or as rounded as shown in Figure 401. In this case, the contact surface between the spices and the lid is smoother, making it easier to clean when the contact surface is contaminated.

[0104] The handle 401-3 can be a split design, but for easier processing and use, the handle 401-3 is integrally set on the outer shell 401, which can be processed in one go and the processing process is relatively short.

[0105] The outer casing 401 can adopt a flip-top design, and the cover can be placed on any end face of the spice box. For ease of operation, the outer casing 401 is composed of two interlocking shells, making installation convenient.

[0106] In order to seal the through hole 401-2, a soft head 404-2 is provided on the end of the extrusion needle 404 away from the tip 404-1. The soft head is made of elastic material and can automatically rebound after being pressed. After the tip 404-1 is pressed into the spice bag, the soft head 404-2 can be stuck in the through hole 401-2 to prevent slippage and blockage of the through hole 401-2, so that the spice in the spice bag will not leak out from the through hole.

[0107] To control the insertion depth of the extrusion needle 404, the extrusion needle 404 can be designed with a thread or an annular groove. During use, the thread can be rotated or extruded as needed to control the depth to which the extrusion needle 404 penetrates the spice packet 402.

[0108] To prevent the squeezing needle 404 from being squeezed and piercing the spice packet 402 during transportation, a pull ring 405 can be added to the spice box. The squeezing needle 404 has at least one annular groove 404-3 in the middle, and one end of the pull ring 405 has a locking slot 405-1 that engages with the annular groove 404-3 of the squeezing needle 404.

[0109] The pull ring 405 is used to limit the extrusion needle 404. Therefore, any device with a limiting function can replace the pull ring 405. For example, a removable retaining ring can be used, or a hole can be drilled in the extrusion needle 404 and a needle-shaped object can be passed through the hole in the extrusion needle 404 to limit the extrusion needle 404.

[0110] If a pull ring is used for limiting the pull, as shown in Figure 401, a second anti-slip ridge 405 can be provided on the end of the pull ring 405 away from the latch 405-1. This increases the friction when pulling out the pull ring, making it easier to use. Of course, any alternative to the pull ring can be used for the second anti-slip ridge 405-2. For example, the cross-sectional area of ​​the pull ring 405 away from the squeeze needle 404 can be increased, the middle of the pull ring can be designed as a ring that allows a finger to be inserted, or concave textures can be provided on its surface. These designs can increase the force between the hand and the pull ring, making it easier for the user to remove the pull ring.

[0111] With the open side of the lid 2 as the front end and the opening of the cup body as the top, the rear end of the lid 2 is rotatably connected to the rear end of the body 1, while the front end is connected to the body 1 via a latch 6. When the latch 6 is open, the lid 2 can flip backward, at which point the straw 3 pops out from the groove 1-1, with the straw 3 pointing upward, allowing for direct drinking. When the latch 6 has a spring mechanism, pressing the latch 6 will automatically flip the lid 2 upward, allowing the user to open the latch 6 with one hand. During use, the lid 2 remains connected to the body 1 and does not need to be removed. This design avoids contamination caused by contact with other items after removing the lid or the possibility of the lid being lost due to user negligence.

[0112] The rear end of the main body 1 is provided with a rotating part 1-3, and a rotating shaft 1-4 is horizontally inserted through the rotating part 1-3. Two spaced-apart rotating ears 2-3 extend downward from the rear end of the lid 2, and the two rotating ears 2-3 are rotatably connected to the two ends of the rotating shaft 1-4 respectively. During the opening of the lid 2, the rotating part 1-3 and the rotating ears 2-3 move relative to the rotating shaft 1-4. This symmetrical rotating ear design allows for more even force distribution on both ends of the rotating shaft, extending the lifespan of the rotating part between the main body and the lid.

[0113] The rotating part 1-3 of the main body 1 includes a rotating seat 1-3-1, a torsion spring 1-3-2, and a torsion spring cover 1-3-3. The rotating seat 1-3-1 is integrally disposed at the upper rear part of the main body 1. A receiving cavity is provided on one side of the rotating seat 1-3-1, and one side of the torsion spring cover 1-3-3 extends into the receiving cavity of the rotating seat 1-3-1 and is rotatably connected to the rotating seat 1-3-1. The rotating shaft 1-4 passes through the rotating seat 1-3-1 and the torsion spring cover 1-3-3. The torsion spring 1-3-2 is located in the accommodating cavity of the rotating seat 1-3-1 and connects the rotating seat 1-3-1 and the torsion spring cover 1-3-3; an upper arc-shaped boss 1-3-4 is provided on the outer circumferential surface of the other side of the torsion spring cover 1-3-3; a lower arc-shaped boss 2-3-1 is provided on the inner side of one of the rotating ears 2-3 of the body 1; the upper arc-shaped boss 1-3-4 of the torsion spring cover 1-3-3 overlaps on the lower arc-shaped boss 2-3-1 of the rotating ear 2-3.

[0114] The torsion spring design effectively maintains the opening and closing state of the cup lid and preserves its stability. The torsion spring cover 1-3-3 can semi-enclose the torsion spring 1-3-2, preventing it from direct contact with air and extending its service life.

[0115] Alternatively, the torsion spring cover can be designed to be fully enclosed, completely eliminating contact with air and further extending its lifespan.

[0116] The latch 6 includes a locking button 6-1, a locking torsion shaft 6-2, a spring 6-3, and a locking button 6-4; the front end face of the body 1 is provided with a locking torsion groove 1-5; the locking torsion shaft 6-2 is horizontally inserted through both sides of the locking torsion groove 1-5; the locking button 6-1 is located inside the locking torsion groove 1-5, and the middle part of the locking button 6-1 is rotatably connected to the locking torsion shaft 6-2; the upper part of the locking button 6-1 is provided with a lower hook 6-1-1, and the front end of the cover 2 is provided with an upper hook 2-4 suitable for cooperating with the lower hook 6-1-1; the spring 6-3 is located between the lower part of the locking button 6-1 and the locking torsion groove 1-5; the locking button 6-4 is U-shaped, located outside the locking torsion groove 1-5, and the two ends of the locking button 6-4 are rotatably connected to the two ends of the locking torsion shaft 6-2 respectively.

[0117] When the cover 2 moves downward to a near-closed state, the lower latch 6-1-1 and the upper latch 2-4 engage, locking the cover 2 and the body 1, preventing the cover 2 from moving. Since the upper and lower parts of the locking button 6-1 form a lever structure with the locking torsion shaft 6-2 as the fulcrum, if it is necessary to open the cover 2, press down the lower part of the locking button 6-1, and the upper part of the locking button 6-1 moves in the opposite direction. At this time, the engagement between the lower latch 6-1-1 and the upper latch 2-4 is locked, and the cover 2 opens.
