Water bottle cap

Abstract

We provide water bottle caps that can meet different drinking needs, such as drinking small amounts directly from the bottle and drinking large amounts directly from the bottle. [Solution] The main cap 2, when the first opening 21 is formed and attached to the water bottle body, includes a main cap 2 that provides a first path connecting to the inside of the water bottle body with the first opening 21, and a sucking part that extends upward and is C-shaped and facing the first opening 21, with a second opening 31 provided at the sucking part, and when the main cap 2 is attached to the water bottle body, the second opening 31 provides a second path connecting to the inside of the water bottle body. A horizontal gap 22 is provided between the first opening 21 and the sucking part, with the first opening 21 located at a lower position and the second opening 31 located at a higher position. As a result, when the water bottle body is tilted for direct drinking, the horizontal gap 22 is converted into a stepped surface with a difference in height that can mitigate the impact of the water flow, the lips cannot simultaneously cover the entire sucking part and the first opening 21, and airflow during direct drinking is ensured.

Description

Technical Field

[0001] The present invention relates to the technical field of daily necessities, and particularly to a water bottle cap.

Background Art

[0002] To meet different drinking needs, some water bottles are provided with two drinking mouths, a direct drinking mouth and a sucking mouth, on the water bottle cap.

Summary of the Invention

Problems to be Solved by the Invention

[0003] In order to prevent the two from interfering with each other during use, it is necessary for the water bottle cap to be able to open and close the direct drinking mouth and the sucking mouth separately. The structure of the water bottle cap is complex and the usability is poor. Moreover, since the sucking mouth cannot be used for direct drinking, the direct drinking mouth alone cannot meet the need for a large amount of drinking. In some designs, two mouths are provided in the same sucking part, with the front mouth for sucking and the rear mouth for direct drinking. However, when used for direct drinking, the lips tend to cover both mouths simultaneously, resulting in a problem that the intake of air is not smooth and the fluid flows out intermittently.

Means for Solving the Problems

[0004] To solve the above problems, the present invention provides a water bottle cap. Through the combined design of the height difference arrangement and horizontal interval of the first opening, the second opening and the sucking part, the water bottle using the water bottle cap can meet different drinking needs such as sucking, small amount of direct drinking, and large amount of direct drinking.

[0005] The present invention is a main cap for being attached to a water bottle body, wherein a first opening is formed in the main cap, and when the main cap is attached to the water bottle body, the first opening provides a first path connecting to the inside of the water bottle body, and the main cap The main cap includes a suction portion which extends upward and is C-shaped and facing the first opening, and a second opening is provided in the suction portion, and when the main cap is attached to the water bottle body, the second opening provides a second path that connects to the inside of the water bottle body, A horizontal gap is provided between the first opening and the suction part, at least in the direction of the line connecting the first opening and the second opening, with the first opening positioned lower and the second opening positioned higher. When the water bottle body is tilted in a direction from the first opening to the second opening for direct drinking, the horizontal gap is converted into a stepped surface that can mitigate the impact of the water flow. This prevents the lips from simultaneously covering the entire suction part and the first opening, and ensures sufficient airflow during direct drinking. This solution is achieved by a water bottle cap.

[0006] Further improvements to the present invention are as follows: further comprising a connecting portion communicating with the second opening, and a tube selectively connected to the connecting portion, wherein the first opening provides a first path to a first portion of the water bottle body, and the second opening, the connecting portion, and the tube provide a second path to a second portion of the water bottle body.

[0007] Further improvements to the present invention are as follows: When the water bottle cap is viewed from above, the centers of the first opening, the second opening, and the main cap are on the same straight line, and the height of the mouthpiece decreases from the second opening toward both sides.

[0008] Further improvements to the present invention are as follows: further comprising a subcap for providing controlled passages to the first and second openings, the subcap being provided on the main cap and having a length that can straddle the first and second openings simultaneously, and one end of the subcap in the longitudinal direction being pivotably connected to the main cap, the subcap being swingable between an open position and a closed position, when swinging to the open position the first and second openings open, and when swinging to the closed position the first and second openings close.

[0009] Further improvements to the present invention are as follows: The subcap is Z-shaped overall and includes a first cap plate, a second cap plate, and a connecting plate connected between the front end of the first cap plate and the rear end of the second cap plate, wherein when the subcap swings to the closed position, the first cap plate abuts against the upper surface of the main cap to close the first opening, the second cap plate abuts against the upper surface of the suction portion to close the second opening, and the connecting plate abuts against the side wall of the suction portion facing the first opening.

[0010] Further improvements to the present invention are as follows: A first rubber column is formed at a position corresponding to the first opening of the subcap, and a second rubber column is formed at a position corresponding to the second opening of the subcap. When the subcap swings to the closed position, the first rubber column is inserted into the first opening by interference fit, and the second rubber column is inserted into the second opening by interference fit.

[0011] Further improvements to the present invention are as follows: The cross-sectional dimensions of the subcap are matched to the cross-sectional dimensions of the main cap, and when the subcap swings to the closed position, the subcap covers the entire upper surface of the main cap, closing the first and second openings simultaneously.

[0012] Further improvements to the present invention are as follows: A first engaging portion is provided at the other end in the longitudinal direction of the subcap, and a second engaging portion is provided on the suction portion or the main cap. When the subcap swings to the closed position, the first engaging portion and the second engaging portion come into contact and lock together. The first engaging portion or the second engaging portion is structured to deform or move when subjected to a predetermined external force, thereby releasing the lock between the first engaging portion and the second engaging portion.

[0013] Further improvements to the present invention are as follows: further comprising a locking member for locking the subcap in the closed position, the locking member being movablely connected to the main cap and movable between an on position and a locked position, the subcap and the locking member being in contact and fixed to each other when the subcap swings to the closed position and the locking member is moved to the locked position, the locking member including an outwardly extending handle, the locking member and the handle being configured such that when the handle is operated, the locking member moves between the on position and the locked position.

[0014] Further improvements to the present invention are as follows: The shape of the second opening is circular or a regular polygon.

[0015] The design of the first opening, second opening, and suction part in combination with a height difference and horizontal spacing allows the second opening to be used as both a suction port and a direct drinking port. When used as a direct drinking port, there is a ventilation space between the first and second openings, ensuring smooth direct drinking. Furthermore, the horizontal spacing reduces the impact force of the fluid flowing out of the second opening when drinking directly, preventing choking. In addition, the arrangement of the tilt angle of the water bottle body when drinking directly can meet different direct drinking needs, such as small and large direct drinking. Moreover, by designing the suction part in a C-shape facing the first opening, when the water bottle body is tilted for direct drinking, the fluid that flows out first from the first opening can be temporarily stored in the area between the suction part and the first opening. This is convenient for the user to first feel the temperature of the fluid on their lips and prevents the problem of hot fluid directly entering the mouth and causing burns.

[0017] Conventional double-mouth water bottle caps have a complex structure, are inconvenient to use, and cannot meet the need for large-volume direct drinking. To solve this problem, the present invention provides a water bottle cap. The design of the water bottle cap will be further described below with reference to the drawings, using specific embodiments of the present invention.

[0018] [First Embodiment] As shown in Figures 1 to 21, the water bottle cap according to the present invention includes a main cap 2 and a mouthpiece 3. The main cap 2 has a side wall that extends downward, and is screw-connected to the mouth of the water bottle body 1 via this side wall, thereby enabling attachment to the water bottle body 1. The main cap 2 has a first opening 21, and the first opening 21 may be any closed shape such as a circle, an ellipse, or a polygon. When the main cap 2 is attached to the water bottle body 1, the first opening 21 provides a first path for connecting to the inside of the water bottle body 1. The suction portion 3 is provided on the main cap 2, extends upward from the upper surface of the main cap 2, and is C-shaped, facing the first opening 21. The suction portion 3 is provided with a second opening 31, which is preferably a circle and any regular polygon with equal length and width dimensions. When the main cap 2 is attached to the water bottle body 1, the second opening 31 provides a second path that connects to the inside of the water bottle body 1. Here, a horizontal gap 22 is provided between the first opening 21 and the suction portion 3 in the direction of the line connecting the first opening 21 and the second opening 31 (i.e., a certain horizontal clearance distance exists between the annular inner wall 32 of the suction portion 3 facing the first opening 21 and the first opening 21), and the first opening 21 is located at a low position. Because the second opening 31 is positioned at a high position, when the water bottle body 1 is tilted in a direction from the first opening 21 toward the second opening 31 for direct drinking, the lips cannot simultaneously cover the entire mouthpiece 3 and the first opening 21, thus ensuring sufficient airflow during direct drinking. Specifically, as shown in Figures 6 and 18, the dotted lines in the figures represent the outer contour of the user's upper lip. When the water bottle body 1 is tilted for direct drinking, it is difficult to cover both the first opening 21 and the second opening 31 simultaneously. This allows outside air to enter the water bottle body 1 through the exposed portion of the second opening 31, thus achieving the objective of circulating internal and external air. Even if the user opens their mouth wide and covers both the first opening 21 and the second opening 31, the suction portion 3 is C-shaped overall and has a height difference with the upper surface of the main cap 2. Therefore, the inner corner portion formed between the suction portion 3 and the upper surface of the main cap 2 (i.e., the area indicated by the dotted arrow excluding the first opening 21) is not completely blocked by the upper lip, and air can still flow between the inside and outside. The circulation of internal and external air makes direct drinking smoother.

[0019] Furthermore, the suction portion 3 extends upward and is C-shaped overall, facing the first opening 21, and a horizontal gap 22 is provided between the suction portion 3 and the first opening 21. Therefore, when the water bottle body 1 is tilted in a direction that points from the first opening 21 to the second opening 31 (as shown in Figure 8), the annular inner wall 32 of the suction portion 3 can, on the one hand, block a portion of the fluid flowing out from the first opening 21. On the other hand, the horizontal gap 22 is converted into a stepped surface, which can mitigate the impact that the fluid in this area has on the annular inner wall 32. Specifically, the fluid flowing out from the first opening 21 first passes over the stepped surface, then through the annular inner wall 32 of the suction section 3, and then enters the mouth together with the fluid flowing out from the second opening 31. As shown in Figure 8, the fluid path is extended by the horizontal spacing 22 and the annular inner wall 32, jointly forming a fluid buffer region Q0. The dotted line in Figure 8 represents the fluid surface contour, and this fluid buffer region Q0 can compensate for potential discontinuities in fluid flow caused by the difference in height and horizontal distance between the first opening 21 and the second opening 31. Furthermore, the fluid buffer region Q0 can also be used to detect the temperature before drinking by controlling the inclination of the water bottle body 1. Specifically, before drinking directly, the user can first touch the fluid within the fluid buffer region Q0 with their upper lip to feel its temperature, and then continue drinking once it reaches an appropriate temperature. In this way, the risk of burns caused by excessively high fluid temperatures can be significantly reduced.

[0020] In summary, the design of the water bottle cap and the control of the inclination of the water bottle body 1 during use can satisfy the diverse drinking needs of users. For example, when a user wants to drink a liquid, they can insert a straw into the second opening and drink through the straw without having to tilt the water bottle body 1. When the user wants to drink directly from the bottle and needs to sense the temperature of the fluid before drinking, the water bottle body 1 can be tilted at a small angle to allow a small amount of fluid to flow out only from the first opening 21 (i.e., the first path), and the annular inner wall 32 of the suction part 3 prevents the fluid from flowing out from the second opening 31 (i.e., the second path). As shown in Figure 8, the small amount of fluid that initially flows out from the first opening 21 is stored within the fluid buffer region Q0. When the user places the mouthpiece 3 in their mouth, their upper lip first touches the fluid in the fluid buffer region Q0 to feel the temperature of the fluid. If the temperature is appropriate, the user continues to tilt the water bottle body 1, causing the fluid to simultaneously flow out from the second opening 31 and enter their mouth. In this configuration, the second opening 31 is used as a direct drinking spout, and the fluid temperature can be sensed in advance before drinking, thus avoiding the problem of burning the mouth. When the user wants to drink a large amount, tilting the water bottle body 1 further causes a large amount of fluid to flow out simultaneously from the first opening 21 and the second opening 31. The combined action of the two openings satisfies the user's need to drink a large amount directly, and the action of the fluid buffering area Q0 mitigates the impact force of the flowing fluid, reducing the risk of choking.

[0021] Furthermore, the water bottle cap further includes a sub-cap 6 for providing controlled passages to the first opening 21 and the second opening 31. The sub-cap 6 is provided on the main cap 2 and has a length that allows it to straddle both the first opening 21 and the second opening 31 simultaneously. One end of the subcap 6 in the longitudinal direction is pivotably connected to the main cap 2, allowing the subcap 6 to swing between an open position P1 (shown in Figure 5) and a closed position P2 (shown in Figure 10). When it swings to the open position P1, the first opening 21 and the second opening 31 open, and when it swings to the closed position P2, the first opening 21 and the second opening 31 close.

[0022] Specifically, in this embodiment, as shown in Figures 1 to 3, a recessed region Q1 is formed on the upper surface of the main cap 2, both ends of the suction portion 3 extend outward so as to surround the outer circumference of the recessed region Q1, and the first opening 21 is formed within the recessed region Q1. As shown in Figures 5 and 10, the subcap 6 is Z-shaped overall and is divided into a first cap plate 63, a second cap plate 64, and a connecting plate 65 that connects the front end of the first cap plate 63 and the rear end of the second cap plate 64. The thickness of the first cap plate 63 matches the depth of the recessed area Q1, and when the sub-cap 6 swings to the closed position P2, the thickness of the first cap plate 63 matches the depth of the recessed area Q1, and its surface becomes flush with the upper surface of the main cap 2. When the sub-cap 6 swings to the closed position P2, the second cap plate 64 covers the suction portion 3 at least partially, closing the second opening 31, and the connecting plate 65 comes into contact with the surface of the annular inner wall 32 of the suction portion 3. In this embodiment, the sub-cap 6 does not completely cover the top surface of the main cap 2, and is light, small, and refined.

[0023] In order to ensure airtightness when the first opening 21 and the second opening 31 are closed, in this embodiment, a first rubber column 61 is formed on the inner surface of the subcap 6 at a position corresponding to the first opening 21, and a second rubber column 62 is formed on the inner surface of the subcap 6 at a position corresponding to the second opening 31. Specifically, as shown in Figure 5, when the sub-cap 6 swings to the closed position P2, the first rubber column 61 is inserted into the first opening 21 by interference fit, and the second rubber column 62 is inserted into the second opening 31 by interference fit. The aforementioned tight fit means that the dimensions of the inserted object are slightly larger than the dimensions of the object being inserted, and the inserted object is pressed during insertion, increasing the airtightness between the two.

[0024] Preferably, the water bottle cap of this embodiment further includes a connecting portion 4 that communicates with the second opening 31, and a tube 5 that is selectively connected to the connecting portion 4. The first opening 21 provides a first path for connecting to the first part of the water bottle body 1, and the second opening 31, the connecting part 4, and the tube 5 provide a second path for connecting to the second part of the water bottle body 1. Preferably, the length of the tube 5 is such that when the main cap 2 is attached to the water bottle body 1, the lower end of the tube 5 can be inserted to the bottom of the water bottle body 1, and the drink can be consumed even when there is little fluid. By providing tube 5, users can choose their preferred method of drinking as needed. When it is necessary to first sense the temperature of the fluid without drinking, even if there is little fluid in the water bottle body 1, the fluid will not leak out of the second opening 31 even if the water bottle body 1 is tilted, completely avoiding the problem of mouth burns. Furthermore, by providing tube 5, suction can be initiated simply by opening subcap 6, eliminating the need to separately insert a straw into the second opening 31.

[0025] Preferably, in order to adapt the shape of the mouthpiece 3 to the shape of the mouth and improve the drinking experience, the water bottle cap satisfies the following conditions: when viewed from above, the centers of the first opening 21, the second opening 31, and the main cap 2 are on the same straight line, and the height of the mouthpiece 3 decreases from the second opening 31 toward both sides. Furthermore, the position of the annular inner wall 32 of the suction portion 3 corresponding to the first opening 21 is formed as a slope that inclins toward the direction of the second opening 31.

[0026] Preferably, the other end of the subcap 6 in the longitudinal direction is provided with a first engagement portion 71. A second engagement portion 72 is provided on the annular outer wall 33 of the suction portion 3 that faces the annular inner wall 32. The projections of the first engagement portion 71, the second engagement portion 72, the first opening 21, and the second opening 31 lie on the same straight line. In this embodiment, the first engaging portion 71 is fixed to the edge of the second cap plate 64 and extends inward, with an arc-shaped projection formed on its inner side, and the second engaging portion 72 is a recessed hole formed on the surface of the annular outer wall 33. When the subcap 6 swings to the closed position P2, the arc-shaped projection contacts and locks into the recessed hole. When it is necessary to open the subcap 6, the first engaging portion 71 is pulled outward and deformed, which allows the arc-shaped projection to detach from the recessed hole, thereby releasing the lock between the first engaging portion 71 and the second engaging portion 72.

[0027] [Second Example] The following will be explained with reference to Figures 11 to 16. The main difference between this embodiment and the first embodiment is that no recessed area is formed on the surface of the main cap 2, the first opening 21 is directly opened on the upper surface of the main cap 2, and both ends of the suction portion 3 extend outward until the first opening 21 is completely within the area enclosed by the suction portion 3. In this embodiment, a first engagement portion 71 is provided at the other end of the subcap 6 in the longitudinal direction, and a second engagement portion 72 is provided on the side of the main cap 2 that is close to the annular outer wall 33. The first engagement portion 71, the second engagement portion 72, the first opening 21, and the second opening 31 are projected onto the same straight line. In this embodiment, the first engagement portion 71 is fixed to the edge of the second cap plate 64 and extends inward, forming an insert, while the second engagement portion 72 is fixed to the outside of the side wall of the main cap 2 and forms a slot that opens upward. When the subcap 6 swings to the closed position P2, the insert is inserted into the slot, and to prevent the insert from coming out of the slot, arc-shaped projections and recessed holes are provided on the sides of the insert and the slot, which are fitted together. When it is necessary to open the subcap 6, the second engaging portion 72 can be pulled outward to open the upward opening of the second engaging portion 72, and the arc-shaped projection can be detached from the recessed hole. After that, the insert can be pulled upward to release the lock between the first engaging portion 71 and the second engaging portion 72.

[0028] Preferably, in this embodiment, a locking member 8 is further provided between the subcap 6 and the main cap 2 for locking the subcap 6 to the closed position P2. Specifically, the locking member 8 is movably connected to the side of the main cap 2 closer to the shaft and can move between the locked position P3 and the on position P4. When the subcap 6 swings to the closed position P2 and the locking member 8 moves to the locked position P3, the subcap 6 or the shaft comes into contact with the locking member 8 and is fixed to each other, preventing the swinging of the subcap 6 or the rotation of the shaft, thereby achieving locking in the closed position. The locking member 8 includes a handle 81 that extends outward. The locking member 8 and the handle 81 are configured such that when the handle 81 is operated, the locking member 8 moves between the ON position and the locked position. Since the locking member 8 belongs to the prior art, its detailed internal structure is not shown. Furthermore, the range of movement of the locking member 8 is not limited to the range shown in the embodiment. For example, the locking and unlocking by fitting the locking member 8 and the sub-cap 6 can utilize various child locking structures of conventional water bottle caps. Furthermore, since the structure of each component not mentioned in this embodiment is the same as that of the first embodiment, a detailed explanation is omitted here.

[0029] [Third Embodiment] This will be explained with reference to Figures 17 to 21. The main difference between this embodiment and the second embodiment is that the dimensions of the suction portion 3 are smaller than those of the second embodiment, and both ends do not extend outward. As a result, a part of the first opening 21 is within the area enclosed by the suction portion 3, and a part extends outside the area enclosed by the suction portion 3. In this embodiment, the cross-sectional dimensions of the subcap 6 match those of the main cap 2, one end of the subcap 6 in the longitudinal direction (i.e., in the direction of the line connecting the first opening 21 and the second opening 31) is connected to one side edge of the main cap 2 via a shaft, a first engagement portion 71 is provided at the other end of the subcap 6 in the longitudinal direction, and a second engagement portion 72 is provided at the other side edge of the main cap 2, with the first engagement portion 71, the second engagement portion 72, the first opening 21 and the second opening 31 projected onto the same straight line. In this embodiment, the locking structure between the first locking portion 71 and the second locking portion 72 is similar to that of the second embodiment, and similarly consists of the fitting of an insert and a slot and an arc-shaped projection and a recessed hole. However, in this embodiment, when it is necessary to open the subcap 6, the second engaging portion 72 is pressed by the cooperation of the button and the spring, the upward opening of the second engaging portion 72 opens, and the arc-shaped projection is disengaged from the recessed hole. After that, the insert can be pulled upward to release the lock between the first engaging portion 71 and the second engaging portion 72. Naturally, in actual design, the locking mechanism is not limited to the above-described form, and any conventional structural form that can achieve the above-described locking and cooperation can be adopted.

[0030] What needs to be explained is that, as can be seen from the three embodiments described above, the shape of the suction portion 3 is not necessarily a standard C shape. The aforementioned C-shape limitation is merely an approximate shape description, and it may also be a sector-shaped arc segment with matching curvature (as in the first and second embodiments), or a shape with a straight middle section and symmetrically curved ends with changing curvature (as in the third embodiment). However, regardless of the shape, the tendency is to surround the first opening 21 in a way that ensures ease of drinking and the formation of a fluid buffer region Q0. This invention, through a combination design of a first opening, a second opening, and a suction part, allows the second opening to be used as both a suction mouthpiece and a direct drinking mouthpiece. When used as a direct drinking mouthpiece, there is a ventilation space between the first and second openings, ensuring smooth direct drinking. Furthermore, by adjusting the angle of inclination of the water bottle body when drinking directly from it, it is possible to meet different direct-drinking needs, such as drinking small amounts directly and drinking large amounts directly. Furthermore, by designing the mouthpiece in a C-shape facing the first opening, when the water bottle is tilted for direct drinking, the fluid that flows out first from the first opening can be temporarily stored in the area between the mouthpiece and the first opening. This reduces the impact force when a large amount of fluid flows out, prevents choking when drinking large quantities, and is also convenient for the user to first feel the temperature of the fluid with their lips, preventing the problem of hot fluid directly entering the mouth and causing burns.

[0031] The present invention has been described in detail above with reference to the drawings and examples, but those skilled in the art can make various modifications to the present invention based on the above description. Therefore, the specific details in the examples are not intended to limit the present invention, and the scope of protection of the present invention is defined by the appended claims.
