Description

Technical Field

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

[0002] When using additives to make beverages, people often use two methods. One is to pre-dissolve the additives in water to prepare a pre-made beverage, which requires multiple additives to maintain its properties. The other is to extract the flavor on the spot when drinking, such as in coffee and tea. This method generally uses high-temperature hot water and specialized equipment, requiring specific locations and operational skills, making it very inconvenient. Therefore, people have considered adding a flavoring box to the cup to enhance the aroma of the water. For example, patent CN203953174U uses an openable window on the cup wall to place the flavoring, while patent CN203914350U places a removable flavoring box at the bottom of the cup and uses a fan to blow the aroma into the water. Of these methods, the first is very inconvenient to use, requiring the flavoring to be dissolved in the water, requiring specific water temperatures, and necessitating manual operation. The second method uses a fan device, which is overly complex, and the circuitry is prone to damage and has a short lifespan. Both methods involve directly adding flavoring to the water, which can lead to over-addition of flavoring. Therefore, it is essential to develop a drinking device that can reduce the use of additives, stably preserve flavorings, and prevent excessive addition of flavorings. Summary of the Invention

[0003] To address the technical problems of excessive additives, inconvenient flavoring addition, and easy over-addition of flavorings in beverages, the present invention aims to provide a straw cup and its lid.

[0004] The technical solution to achieve the purpose of this invention is as follows: a cup lid, comprising 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 an aroma-expanding guide hole is provided on the outer circumference of the straw; the spice box is slidably connected to the body; an item capable of emitting fragrance is placed in the inner cavity of the spice box, and an aroma-expanding hole is provided on the spice box; the outlet height of the aroma-expanding hole of the spice box is consistent with the outlet height of the aroma-expanding guide hole of the straw; the straw is located in the sliding direction of the spice box, and when the spice box slides to fit against the straw, the aroma-expanding hole of the spice box communicates with the aroma-expanding guide hole of the straw.

[0005] When the fragrance outlet of the fragrance box and the fragrance guide hole of the straw are in a connected state, a fragrance channel can be formed. When the user drinks water, the fragrance escapes from the fragrance box, enters the straw through the fragrance channel, and rises to the olfactory mucosa after passing through the throat. Only a very small amount of fragrance is needed for the user to perceive the presence of the fragrance.

[0006] The spice box is slidably connected to the main body; simply sliding the spice box will connect the spice channels. The spice box can be slidable manually or through a linkage mechanism.

[0007] The specific implementation of the linkage structure is as follows: a linkage structure is provided between the spice box and the lid, or between the spice box and the body and the lid. This linkage structure enables the spice box and the lid to be linked. When the lid is open, there is at least one position where the fragrance overflow hole of the spice box is connected to the fragrance overflow guide hole of the straw. When the lid is closed, the fragrance overflow hole of the spice box is offset from the fragrance overflow guide hole of the straw.

[0008] When the spice box is connected to the main body and the lid by a linkage structure, after the lid is opened, the linkage structure allows the spice box to automatically slide to the position where the spice channel is connected, without the need for manual adjustment.

[0009] Furthermore, the main body is provided with a groove; the spice box is slidably disposed within the groove of the main body. Using a groove structure to define the position of the spice box can effectively limit its movement path, enabling more effective control over it.

[0010] Furthermore, the linkage structure includes an elastic element disposed in the groove, a wedge disposed on the spice box, and a wedge-shaped pusher disposed on the lid; the elastic element provides a force for the spice box to move away from the straw; when the lid is closed, the wedge-shaped pusher cooperates with the wedge on the spice box to push the spice box to move towards the straw.

[0011] The use of a flexible element allows the spice box to move to a position where the spice outlet and the spice guide hole of the straw are connected when the cup lid is opened, ensuring unobstructed spice channels. At this time, no manual operation is required, making it very convenient to use.

[0012] Furthermore, the linkage structure includes a connecting rod; one end of the connecting rod is rotatably connected to the lid, and the other end is rotatably connected to the spice box. When the lid is opened, the connecting rod drives the spice box to move, unblocking the spice channel, and also realizing the automatic connection of the automatic spice overflow hole and the spice overflow guide hole.

[0013] Furthermore, the rear end of the main body is provided with a rotating shaft; the rear end of the cover extends upward with two rotating ears spaced apart; the two ends of the rotating shaft are respectively rotatably connected to the two rotating ears.

[0014] The symmetrical rotating ear design allows for a more balanced force distribution between the body and the cover, and avoids the possibility of the cover separating from the body and being lost.

[0015] Furthermore, at least one end of the rotating shaft is internally provided with a torsion spring; the torsion spring provides an outward opening force for the cover. When the torsion spring cover is in the open state with the main body, the torsion spring is in the relaxed state, which can prevent the cover from flipping towards the main body, thus avoiding inconvenience in use.

[0016] Furthermore, the cover is provided with a sealing block, and the upper end face of the main body is provided with a vent hole that runs vertically through the cover and corresponds to the sealing block. When the cover is closed, the sealing block seals the vent hole of the main body.

[0017] The vent is designed to maintain a balance of air pressure inside and outside the cup, preventing danger caused by excessive air pressure inside the cup or preventing the beverage from being drunk due to insufficient air pressure inside the cup.

[0018] Furthermore, the sealing block of the cover is made of an elastic material. When the cover and the body are in a closed state, the elastic material deforms to achieve a better seal for the vent hole and avoid the possibility of liquid splashing when the cup body is violently impacted.

[0019] Furthermore, the inner end of the fragrance guide hole on the straw is lower than the outer end. This prevents water from flowing back into the fragrance box and damaging it when water passes through the straw.

[0020] The present invention also provides a straw cup, which includes the aforementioned cup lid and a cup body threadedly connected thereto.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects:

[0022] (1) The straw cup and its lid of the present invention adopt a combination of a spice box and a water cup to realize the function of automatically and instantly adding spices. The spice box adopts a translational structure and is equipped with a linkage mechanism, which makes it very convenient to connect the spice box overflow hole and the straw overflow guide hole.

[0023] (2) The straw cup and its lid of the present invention use a groove to limit the spice box, and the connection between the spice box and the lid body is tighter.

[0024] (3) The straw cup and its lid of the present invention use an elastic element to control the position of the spice box, thereby realizing automatic control of the position of the spice box and eliminating the need for manual operation during use.

[0025] (4) The invention uses a combination of a rotating shaft and a torsion spring to make the torsion spring always relaxed when the lid is opened, thus avoiding the possibility of the lid flipping over during use.

[0026] (5) The upper end face of the body of the straw cup and its lid is provided with a vent hole that runs through the upper and lower parts corresponding to the sealing block, so as to maintain the pressure difference balance between the inside and outside of the cup.

[0027] (6) The sealing block of the straw cup and its lid is made of elastic material, which achieves better sealing of the vent hole.

[0028] (7) The inner end of the fragrance guide hole on the tube is lower than the outer end, which avoids the possibility of water flowing back into the fragrance box during use. Attached Figure Description

The present invention will be further described below with reference to the accompanying drawings. 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.

[0050] (Example 1)

[0051] See Figures 1 to 5 The straw cup of this embodiment includes a threaded cup lid and a cup body 5, wherein the cup lid includes a body 1, a lid 2, a straw 3 and a spice box 4.

[0052] The lid 2 is connected to the body 1 and has at least two states: open and closed. The straw 3 is inserted through the body 1 and has an internal and external fragrance guide hole 3-1 on its outer circumferential surface. The spice box 4 is slidably connected to the body 1. The inner cavity of the spice box (4) contains an item that can emit fragrance, and the spice box 4 has an internal and external fragrance guide hole 4-1. The outlet height of the fragrance guide hole 4-1 of the spice box 4 is the same as the outlet height of the fragrance guide hole 3-1 of the straw 3. A linkage structure is provided between the spice box 4 and the lid 1, or between the spice box 4 and the body 1 and the lid 2. This linkage structure makes the spice box and the lid linked. When the lid 2 is open, there is at least one position where the fragrance guide hole 4-1 of the spice box 4 is connected to the fragrance guide hole 3-1 of the straw 3. When the lid 2 is closed, the fragrance guide hole 4-1 of the spice box 4 is offset from the fragrance guide hole 4-1 of the straw 3.

[0053] In the above scheme, the spices are placed in the spice box 4, and then the spice is transported through the spice overflow channel formed between the spice overflow guide hole 3-1 and the spice overflow hole 4-1. In this scheme, the spice box 4 is connected to the body 1 and the cover 2 by a linkage structure to control the positional relationship between the straw 3 and the spice box 4, so as to achieve the purpose of adding spices. There is no need to manually align the positional relationship between the spice overflow guide hole 3-1 and the spice overflow hole 4-1. It is convenient and saves time and effort when using it.

[0054] The main body 1 is provided with a groove 1-1; the spice box 4 is slidably disposed in the groove 1-1 of the main body.

[0055] The spice box 4 is placed in the groove 1-1 to restrict its movement path. Therefore, the shape of the groove 1-1 is not restricted, as long as the spice box 4 can be stably fixed.

[0056] There are several ways to design the linkage structure, such as using an elastic element and a wedge block to cooperate with each other, or using a connecting rod.

[0057] When the elastic element and wedge are used in conjunction, the linkage structure includes an elastic element 1-2 disposed in the groove 1-1, a wedge 4-2 disposed on the spice box 4, and a wedge-shaped pusher 2-1 disposed on the lid 2. The elastic element 1-2 provides a force for the spice box 4 to move away from the straw. When the lid 2 is closed, the wedge-shaped pusher 2-1 cooperates with the wedge 4-2 on the spice box 4, pushing the spice box 4 towards the straw 3. Using the elastic element, when the lid is opened, the spice box is moved to a position where the aroma outlet and the aroma guide hole of the straw are connected, ensuring unobstructed aroma passage. At this time, no manual operation is required, making it very convenient to use.

[0058] When a linkage mechanism is used, the linkage structure includes a connecting rod; one end of the connecting rod is rotatably connected to the lid 2, and the other end is rotatably connected to the spice box 4. When the lid is opened, the connecting rod drives the spice box to move, the spice channel is unobstructed, and the automatic connection of the automatic spice overflow hole and the spice overflow guide hole can also be realized.

[0059] The linkage structure is designed to more conveniently control the connection status of the fragrance channel. In terms of setup, it is only necessary to ensure that the outlet height of the fragrance guide hole 3-1 of the straw 3 is consistent with the outlet height of the fragrance hole 4-1 of the fragrance box 4. It is not a necessary device. In practice, the connection of the fragrance channel can be achieved by pushing manually.

[0060] The rear end of the main body 1 is provided with a rotating shaft 1-3; the rear end of the cover 2 extends upward with two rotating ears 2-2 spaced apart; the two ends of the rotating shaft 1-3 are respectively rotatably connected to the two rotating ears 2-2.

[0061] The purpose of using a rotating connection is to place a torsion spring in the rotating shaft 1-3 to keep the cup lid open, while preventing the lid 2 from being lost. If the connection of the spice channel is controlled by a push-type method, a split structure can be used between the body 1 and the lid 2.

[0062] At least one end of the rotating shaft 2-2 is provided with a torsion spring 2-3; the torsion spring 2-3 provides an outward opening force for the cover 2. The torsion spring 2-3 is provided to keep the cover 2 in the open state, and it can be replaced by other methods.

[0063] The cover 2 is provided with a sealing block 2-4, and the upper end face of the body 1 is provided with a vent hole 1-4 that runs vertically through the sealing block. When the cover 2 is closed, the sealing block 2-4 seals the vent hole 1-4 of the body.

[0064] The vent is designed to maintain pressure balance inside and outside the cup. After use, the internal pressure drops, allowing air to enter through the vent 1-4, thus equalizing the internal and external pressures. One or more vents 1-4 can be present. A rubber sealing film is typically located on the side closest to the cup body 5, with cross-shaped slits to allow air to enter from the outside while preventing water from overflowing from the lid 2. This structure, in conjunction with the sealing blocks 2-4, ensures that the liquid inside the cup will not spill out in the event of impact or violent movement.

[0065] The sealing blocks 2-4 of the cover 2 are made of elastic material.

[0066] When the cover 2 is in the closed state, the sealing block 2-4 deforms, partially blocking the vent hole 1-4, thus achieving a better sealing effect on the vent hole 1-4.

[0067] The inner end of the fragrance guide hole 3-1 on the straw is lower than the outer end.

[0068] This design prevents backflow of water as it passes through the straw, thus preventing the spices in the spice box from spoiling.

[0069] The specific structure of the spice box 4 mentioned above is as follows:

[0070] like Figures 6 to 8 The fragrance box shown includes an outer shell and a fragrance-emitting substance 4-6 disposed inside the outer shell; the front end of the outer shell has a square notch; the inner side wall of the square notch of the outer shell has an overflow hole 4-1 that runs through the inside and outside; the bottom of the front end of the outer shell has a recessed platform 4-5, and the upper surface of the outer shell has a wedge seat 4-2, the inclined surface of the wedge seat 4-2 being located on the side opposite to the recessed platform 4-5.

[0071] The fragrance-emitting substance 4-6 is used to absorb fragrance and can be one or more of the following: sponge, degreased cotton, alumina, activated carbon, silica gel, and non-woven fabric.

[0072] The wedge 4-2 here is for cooperation with the externally installed pushing device to realize the movement of the spice box. In terms of setup, only a slope is needed to achieve its function.

[0073] The purpose of using an adsorbent is to effectively adsorb fragrance. When the fragrance itself is solid, it can be used directly as a filler. The adsorbent can take many forms, such as non-woven fabric, cotton, paper, etc., as long as it can adsorb fragrance.

[0074] The outer shell is provided with ventilation holes 4-7. The ventilation holes 4-7 are provided to increase the air permeability of the spice box 4. There can be one or more ventilation holes; the location is not limited to the top surface, but can be set on the side or other positions, as long as the air permeability function is achieved.

[0075] The outer shell, comprising an interlocking upper shell 4-3 and a lower shell 4-4, adopts a split design to facilitate injection molding. Because the spice box of this utility model has an internal hollow design, separating it from the hollow part allows the projection of one end face of the part to be larger than that of the other end face, making demolding relatively easier. The snap-fit ​​connection, compared with other methods, makes the connection between the spice box parts more stable and environmentally friendly than glue bonding, and also makes the exterior more aesthetically pleasing.

[0076] The side of the wedge 4-2 is trapezoidal. As mentioned earlier, the wedge 4-2 is provided to push the spice box with the external pushing device, so its cross-section can be trapezoidal or triangular; the setting area can be the middle position of the upper end face of the spice box or the entire upper end face. For the purposes of aesthetics, material saving and ease of manufacturing, the side of the wedge 4-2 is preferably a right trapezoid and is set in the middle of the upper end face of the spice box.

[0077] The four corners of the outer periphery of the shell are all rounded. The rounded transitions are for aesthetic reasons, and also to allow the contact surfaces to be rounded for easier cleaning. In addition, this design can reduce shrinkage during the cooling process after demolding, which helps to improve the yield.

[0078] The fragrance outlet 4-1 is sealed with a sealing film. The sealing film design is to prevent fragrance leakage. In actual production, other methods can be used instead, such as sealing with a stopper or directly covering it with a plastic packaging bag.

[0079] The bottom surface of the outer casing has a rounded transition with the outer perimeter. The reason for this rounded transition is the same as that at the corners mentioned above, which is based on considerations of aesthetics, the difficulty of cleaning the external bonding parts, and the yield rate.

[0080] (Example 2)

[0081] This embodiment is basically the same as embodiment 1, except that: the cup lid in this embodiment does not have a linkage structure, and the spice box slides manually by the user.

[0082] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
