Description

Technical Field

[0001] This application relates to the field of metering cap technology, and in particular to a coffee metering cap. Background Technology

[0002] Coffee powder is a powder made from roasted coffee beans, commonly used for brewing coffee and a key ingredient in making coffee beverages. In daily life, coffee powder left out in the open for too long usually affects the flavor of the brewed coffee.

[0003] Coffee powder is usually packaged in bottles or bags. When taking coffee powder, people usually rely on experience to use a spoon or open the bottle or bag containing coffee powder and pour it out.

[0004] The above method of taking coffee powder relies on human experience and cannot control the amount of coffee powder used, thus making it impossible to control the concentration of the brewed coffee, which is something that needs improvement. Utility Model Content

[0005] In order to achieve the purpose of quantitative dispensing of coffee powder and thus control the concentration of brewed coffee, this application provides a coffee dispensing cap.

[0006] This application provides a coffee dispensing cap, which adopts the following technical solution:

[0007] A coffee dispensing bottle cap includes: a rotatably fitted cap and a housing, wherein the side of the housing away from the cap is detachably fixed to a container bottle, a receiving cylinder is disposed between the cap and the housing, the receiving cylinder is fixed to the housing, a dispensing cavity is provided inside the receiving cylinder, a dispensing port is provided on the cap, and a dispensing port is provided on the housing, wherein as the cap and the housing rotate relative to each other, the dispensing cavity communicates with the dispensing port and the dispensing port respectively.

[0008] By adopting the above technical solution, when the user uses the metering cap, the user installs the metering cap on the mouth of the container, rotates the cap to connect the metering chamber with the inlet, and inverts the container so that the outlet faces the ground. Coffee powder falls from the inside of the container into the metering chamber. When the coffee powder fills the metering chamber, the user rotates the cap to connect the metering chamber with the outlet, and the coffee powder in the metering chamber slides out of the metering chamber through the outlet. This setting achieves the metered use of coffee powder, thereby achieving the purpose of controlling the concentration of brewed coffee.

[0009] Optionally, the housing includes a first baffle plate, a shell plate and a fixed cylinder that are fixed to each other, the inlet is opened on the first baffle plate, the first baffle plate is rotatably connected to the shell plate on the side away from the shell cover; the fixed cylinder is connected to the shell plate on the side away from the shell cover, a snap-fit ​​post is fixed on the side of the first baffle plate near the shell cover, the snap-fit ​​post is rotatably connected to the inner wall of the fixed cylinder, and the end of the snap-fit ​​post abuts against the shell cover.

[0010] By adopting the above technical solution, when the metering chamber is connected to the inlet, the metering chamber is isolated from the outlet. When the user rotates the cover, it rotates relative to the cover and the receiving cavity. At this time, the cover drives the second baffle plate to rotate, and the metering chamber is connected to the outlet, while the metering chamber is isolated from the inlet. This setting realizes the function that the metering chamber will not be connected to both the inlet and the outlet at the same time.

[0011] Optionally, the cover includes a cover plate and a rotating shaft that are fixed to each other. The discharge port is opened on the cover plate. The rotating shaft is located on the side of the cover plate near the housing. The end of the rotating shaft away from the cover plate is provided with an abutment interface. The end of the snap-fit ​​post away from the first blocking plate is provided with an abutment surface. The abutment surface abuts against the inner wall of the abutment interface. The abutment surface and the abutment interface are used to restrict the circumferential rotation of the first blocking plate.

[0012] By adopting the above technical solution, when producing quantitative bottle caps, the cap is snapped onto the end of the snap-fit ​​post away from the first baffle plate. The contact surface of the snap-fit ​​post away from the first baffle plate mates with the contact interface. The cap can slide axially on the snap-fit ​​post, but the rotation of the cap in the circumferential direction of the snap-fit ​​post is restricted. When the cap rotates, it drives the snap-fit ​​post to rotate, so that the first baffle plate and the cap rotate at the same speed. This setting enables the first baffle plate and the cap to rotate simultaneously in the circumferential direction of the cap.

[0013] Optionally, the cover further includes a cover body fixed to the side of the cover plate near the cover plate. The cover body is disposed along the edge of the cover plate. The shell also includes a retaining plate fixed to the cover plate. The cover further includes a retaining strip fixed to the inner side of the cover body. A retaining groove is provided on the outer side of the retaining plate. The retaining strip engages with the retaining groove and is rotatably connected to the inner wall of the retaining groove.

[0014] By adopting the above technical solution, the user can clamp the cap onto the shell plate by cooperating with the locking strip and the locking slot. At this time, the locking strip and the locking plate are engaged. When the user uses the quantitative bottle cap, the user holds the cap and controls the cap plate to rotate. The locking strip rotates inside the locking slot, reducing the possibility of the cap moving away from the shell plate and realizing the circumferential rotation of the cap on the shell plate.

[0015] Optionally, a second blocking plate is rotatably connected to the side of the cover plate near the shell plate. The second blocking plate is fixed to the outer side of the receiving cylinder. A locking groove is provided on the side wall of the receiving cylinder. A first locking block and a second locking block are respectively fixed to the side of the shell plate near the shell plate. Both the first locking block and the second locking block are engaged with the locking groove. When the first locking block engages with the locking groove, the metering cavity is connected to the inlet. When the second locking block engages with the locking groove, the metering cavity is connected to the outlet.

[0016] By adopting the above technical solution, when the metering chamber is connected to the inlet, the first locking block and the locking groove cooperate to block the rotation of the cover on the plate. The user needs to use a little more force to make the cover rotate. When the user rotates the cover to connect the metering chamber to the outlet, the second locking block and the locking groove cooperate to align the metering chamber with the outlet, reducing the possibility that the user will operate the cover to rotate too much.

[0017] Optionally, the housing further includes a surrounding plate fixed to the side of the housing plate away from the cover plate. The surrounding plate is arranged circumferentially along the housing plate. A locking plate is fixed to the inner wall of the surrounding plate. The locking plate cooperates with the bottle mouth of the bottle. A support plate is fixed to the side of the locking plate away from the housing plate. The support plate and the locking plate are arranged at an angle.

[0018] By adopting the above technical solution, before the user uses the metering cap to take coffee powder, the user uses the baffle and the locking plate to lock the metering cap to the mouth of the container. Under the action of the locking plate, the metering cap is stably fixed at the mouth of the container. The setting of the support plate increases the structural strength of the metering cap and reduces the possibility of deformation of the metering cap during the twisting process.

[0019] Optionally, a first indicator plate and a second indicator plate are fixed to the outer side of the cover, both of which are located near the enclosure plate. An indicator block is fixed to the outer side of the enclosure plate, located near the enclosure plate. An indicator for indicating the rotation direction of the cover plate is provided on the side of the cover plate away from the enclosure plate. When the first indicator plate is close to the indicator block, the metering cavity is connected to the inlet. When the second indicator plate is close to the indicator block, the metering cavity is connected to the outlet.

[0020] By adopting the above technical solution, when a user uses the metering cap, the user rotates the cap so that the first indicator piece is close to the indicator block. At this time, the first locking block engages with the locking groove, and the metering cavity is aligned and connected with the inlet. The user inverts the container, and the coffee powder falls from the container into the metering cavity. Subsequently, the user rotates the metering cap according to the direction indicated by the indicator piece. At this time, the second indicator piece is close to the indicator block, and the second locking block engages with the locking groove. The metering cavity is aligned and connected with the outlet, and the coffee powder slides out from the inside of the metering cavity through the outlet. This setting makes it easy for the user to identify the relative position information between the cap and the shell, improving the accuracy of the user's metering process for coffee powder.

[0021] Optionally, the outer side of the cover is provided with several grooves, which are located on the cover away from the cover plate.

[0022] By adopting the above technical solution, the groove design makes it easier for users to grip the shell, making it easier for users to rotate the cap and improving the practicality of the metering cap.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Before using the metering cap, the user installs the side of the housing away from the cap onto the mouth of the container. Then, the user rotates the cap to connect the metering chamber with the inlet. At this point, the user inverts the container so that the cap is closer to the ground than the housing. The coffee powder inside the container falls into the metering chamber through the inlet. Then, the user rotates the cap to connect the metering chamber with the outlet, and the coffee powder slides out from the metering chamber. This setting achieves the metered dispensing of coffee powder, thereby achieving the purpose of controlling the concentration of the brewed coffee.

[0025] 2. When the user installs the quantitative bottle cap, the user operates the shell plate close to the bottle opening. At this time, the locking plate and the surrounding plate cooperate with the bottle opening, realizing the installation of the quantitative bottle cap to the bottle opening. The setting of the support plate improves the structural strength of the locking plate on the inner wall of the surrounding plate, reducing the probability of deformation of the locking plate during the user's rotation of the quantitative bottle cap.

[0026] 3. When the user uses the metering cap, the user rotates the cap to align the indicator block with the first indicator piece. At this time, the metering chamber is connected to the outlet. The user rotates the cap to align the indicator block with the second indicator piece. At this time, the metering chamber is connected to the dispensing port. This setting makes it easier for the user to identify the relative position of the cap and the shell, making the process of the user taking coffee powder more stable. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a coffee dispensing bottle cap.

[0033] Reference Figure 1 and Figure 2 A coffee dispensing cap includes a rotatably fitted cap 1 and a housing 2, and a receiving cylinder 3 disposed between them. The receiving cylinder 3 is fixed to the housing 2, and a dispensing cavity 4 is provided inside the receiving cylinder 3 for dispensing a specific amount of coffee powder. The cap 1 has a discharge port 5, and the housing 2 has a feed port 6. During use, the user rotates the cap 1 so that it rotates relative to the housing 2 and the receiving cylinder 3. The dispensing cavity 4 connects sequentially to either the feed port 6 or the discharge port 5, but the dispensing cavity 4 will not be connected to both the feed port 6 and the discharge port 5 simultaneously.

[0034] When using the metering cap, the user first installs the housing 2 on the mouth of the container for holding coffee powder, rotates the cap 1 to connect the inlet 6 with the metering chamber 4, then inverts the container to allow the coffee powder to enter the metering chamber 4 through the inlet 6. At this time, the outlet 5 faces the ground. The user continues to rotate the cap 1 to connect the outlet 5 with the metering chamber 4, and the coffee powder in the metering chamber 4 can slide out of the metering chamber 4 through the outlet 5. This completes one metering process for coffee powder. When the coffee powder is used up, the user inverts the container again, this time with the inlet 6 facing the ground.

[0035] Reference Figure 2The shell 2 includes a shell plate 22 and a retaining plate 24. The receiving cylinder 3 and the retaining plate 24 are integrally formed on the side of the shell plate 22 near the shell cap 1. The retaining plate 24 is used to connect with the shell cap 1. The shell cap 1 includes a cover plate 11 and a cap body 13. The cover plate 11 is circular, and the cap body 13 is cylindrical, with one end connected to the edge of the cover plate 11. The retaining plate 24 has an annular structure and is inserted into the end of the cap body 13 near the shell plate 22. The retaining plate 24 connects the shell plate 22 and the cap body 13 to form a complete bottle cap structure.

[0036] Specifically, the cover 1 also includes a retaining strip 14, which is annular in structure and integrally formed on the inner wall of the cover body 13, with the retaining strip 14 located at the end of the cover body 13 away from the cover plate 11. Meanwhile, the outer wall of the retaining plate 24 has an annular groove 101 along its circumference, and the retaining strip 14 engages with the groove 101 to connect the cover 1 to the housing 2. Furthermore, there is a certain gap between the retaining strip 14 and the inner wall of the groove 101, meaning the retaining strip 14 can rotate relative to the retaining plate 24 with the center of the cover plate 11 as the center, thereby achieving a rotatable connection between the cover 1 and the housing 2.

[0037] Reference Figure 2 and Figure 3 The cover 1 also includes a rotating shaft 12, which is integrally fixed to the side of the cover plate 11 near the cover plate 22. The rotating shaft 12 is located at the center of the cover plate 11. In this embodiment, the cover plate 22 is circular. The housing 2 also includes a fixing cylinder 23, which is integrally fixed to the side of the cover plate 22 near the cover 1. The fixing cylinder 23 is located at the center of the cover plate 22, and the rotating shaft 12 and the fixing cylinder 23 are coaxial.

[0038] The discharge port 5 is opened on the cover plate 11. In this embodiment, the shell plate 22 is provided with a circumferential groove on the side away from the cover plate 11. The circumferential groove has a converging structure along the bottom of the groove towards the opening. The shell 2 also includes a first blocking plate 21 that is engaged with the inner wall of the circumferential groove on the shell plate 22. The first blocking plate 21 is circular. The inlet port 6 is opened on the first blocking plate 21.

[0039] A snap-fit ​​post 7 is fixed on the side of the first baffle plate 21 near the cover plate 11. The snap-fit ​​post 7 has an overall approximately cylindrical structure. The snap-fit ​​post 7 is set perpendicular to the first baffle plate 21. The snap-fit ​​post 7 is located at the center of the first baffle plate 21. An abutment surface 9 is provided at the end of the snap-fit ​​post 7 away from the first baffle plate 21. The abutment surface 9 is a rectangular plane and is formed by the inward indentation of the outer wall of the snap-fit ​​post 7. The abutment surface 9 is set perpendicular to the end face of the snap-fit ​​post 7.

[0040] The rotating shaft 12 has an abutment interface 8 at the end away from the shell plate 22. The inner shape of the abutment interface 8 fits the shape of the end of the snap-fit ​​post 7 located on the abutment surface 9, that is, the end of the snap-fit ​​post 7 is inserted into the abutment interface 8. When the snap-fit ​​post 7 is inserted into the abutment interface 8, the snap-fit ​​post 7 passes through the fixed cylinder 23 and abuts against the end of the rotating shaft 12, that is, the abutment surface 9 abuts against the inner wall of the abutment interface 8. Since the abutment surface 9 is a plane rather than an arc surface, the snap-fit ​​post 7 and the rotating shaft 12 form a circumferential limit for each other, so that when the shell cover 1 rotates, the rotating shaft 12 and the snap-fit ​​post 7 rotate synchronously, thereby driving the first baffle plate 21 to rotate and changing the position of the feed inlet 6 relative to the metering cavity 4.

[0041] Reference Figure 2 and Figure 3 A circumferential groove is also provided on the side of the cover plate 11 near the shell plate 22. A second baffle plate 111 is engaged with the inner wall of the circumferential groove on the cover plate 11. The second baffle plate 111 is arc-shaped and has a cut-off opening. The two ends of the second baffle plate 111 located at the cut-off opening abut against the two sides of the receiving cylinder 3 respectively.

[0042] Viewed axially from the rotating shaft 12, the inlet 6 and outlet 5 are located on opposite sides of the rotating shaft 12. When the metering chamber 4 is connected to the inlet 6, the metering cap is in the first position; when the metering chamber 4 is connected to the outlet 5, the metering cap is in the second position. When the user uses the metering cap, the user rotates the metering cap to the first position, at which time the metering chamber 4 is connected to the inlet 6, and the second baffle plate 111 blocks the outlet 5. When the user rotates the metering cap to the second position, the user holds the cap 13 and rotates the cap. Body 13 causes the cover body 13 to drive the cover plate 11 to rotate. Under the limiting action of the rotating shaft 12 and the locking post 7, the first blocking plate 21 rotates with the rotation of the cover plate 11, and the second blocking plate 111 remains stationary relative to the shell plate 22 under the blocking action of the receiving cylinder 3. As the cover plate 11 rotates, the first blocking plate 21 gradually blocks the inlet 6, and the second blocking plate 111 continues to block the outlet 5. After further rotation, the metering chamber 4 and the outlet 5 gradually connect until the metering bottle cap is in the second posture, and the outlet 5 and the metering chamber 4 are completely aligned.

[0043] Reference Figure 2 and Figure 3Two locking slots 121 are provided at one end of the receiving cylinder 3 near the cover plate 11. One locking slot 121 is located on the side of the receiving cylinder 3 near the rotating shaft 12, and the other locking slot 121 is located on the side of the receiving cylinder 3 away from the rotating shaft 12. Two first locking blocks 131 are fixed to the side wall of the cover plate 11. One first locking block 131 is located on the cover plate 11 away from the rotating shaft 12, and the other first locking block 131 is located on the cover plate 11 near the rotating shaft 12. The two first locking blocks 131 can respectively cooperate with the two locking slots 121. At this time, the quantitative bottle cap is in the first posture. Two second locking blocks 141 are also fixed on the side of the cover plate 11 near the shell plate 22. The second locking blocks 141 are located on the side wall of the cover plate 11 at a position that rotates half a circle with the rotating shaft 12 as the center. When the second locking block 141 cooperates with the locking slot 121, the quantitative bottle cap is in the second posture.

[0044] Reference Figure 2 and Figure 3 The shell 2 also includes a surrounding plate 25 integrally fixed to the side of the shell plate 22 away from the cover plate 11. The surrounding plate 25 has a cylindrical structure. Two locking plates 151 are integrally fixed to the inner wall of the surrounding plate 25. The two locking plates 151 are located on both sides of the inner wall of the surrounding plate 25. The locking plates 151 are inclined and gradually move away from the shell plate 22 in a clockwise direction. Two support plates 161 are integrally fixed to the end of the locking plate 151 away from the shell plate 22. The support plates 161 are set at a perpendicular angle to the shell plate 22 and at an angle to the surrounding plate 25. The two support plates 161 located on the same locking plate 151 are spaced apart.

[0045] Reference Figure 1 and Figure 3 A first indicator piece 171 and a second indicator piece 181 are respectively glued and fixed to the outside of the cover 13. The first indicator piece 171 and the second indicator piece 181 are both located on the cover 13 near the surrounding plate 25. The first indicator piece 171 is near the feed inlet 6, and the second indicator piece 181 is near the discharge outlet 5. An indicator block 191 is glued and fixed to the outside of the surrounding plate 25. The indicator block 191 is located on the outside of the surrounding plate 25 near the feed inlet 6.

[0046] When the user uses the metering cap, the user rotates the housing 2 to bring the first indicator 171 close to the position of the indicator block 191. At this time, the metering cap is in the first position. Then, the user inverts the container, and the coffee powder falls from the inside of the container into the metering chamber 4 through the feed port 6. The user rotates the housing 2 to bring the second indicator 181 close to the position of the indicator block 191. At this time, the metering cap is in the second position, and the coffee powder inside the metering chamber 4 slides out through the discharge port 5. At this time, the user has completed a process of metering coffee powder using the metering cap.

[0047] Reference Figure 3An indicator 201 is provided on the side of the cover plate 11 away from the shell plate 22. In this embodiment, the indicator 201 is preferably a pointer, and the indicator 201 points in a clockwise direction. A plurality of grooves 211 are provided on the outer side of the cover body 13. The grooves 211 are evenly distributed at intervals and are located on the outer side of the cover body 13 near the card strip 14. When the user uses the metering cap, the user grasps the groove 211 and rotates it in the direction pointed by the indicator 201, which makes it convenient for the user to use the metering cap.

[0048] The implementation principle of a coffee metering cap according to an embodiment of this application is as follows: When the user uses the metering cap, the user places the metering cap at the mouth of the container bottle, and then the user rotates the cap 13 so that the first indicator piece 171 is close to the indicator block 191. At this time, the first locking block 131 engages with the locking groove 121, and the metering cap is in a first position. The metering cavity 4 is aligned with and connected to the feed inlet 6. The user inverts the container bottle so that coffee powder falls from the inside of the container bottle into the inside of the metering cavity 4. The user shakes the container bottle slightly so that the coffee powder evenly fills the inside of the metering cavity 4. Then the user rotates the cap 13 so that the second indicator piece 181 is close to the indicator block 191. At this time, the second locking block 141 engages with the locking groove 121, and the metering cap is in a second position. The metering cavity 4 is separated from the feed inlet 6, and the metering cavity 4 is aligned with and connected to the discharge outlet 5. The coffee powder slides out from the inside of the metering cavity 4 through the discharge outlet 5. This setting realizes the metered use of coffee powder, thereby achieving the purpose of controlling the concentration of brewed coffee.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
