TECHNICAL FIELD

[0001] The present application relates to the technical field of instant bottle caps, in particular to a matcha bottle cap. BACKGROUND

[0002] Matcha is a kind of historical beverage, when drinking, only need to pour matcha powder into water and mix evenly.

[0003] Because matcha stored for a long time after brewing will cause poor flavor, therefore, when making bottled beverage for sale, matcha powder and water need to be stored separately, and when drinking, matcha powder is taken out and poured into water in the bottle to mix evenly.

[0004] When designing a bottled matcha beverage, in order to facilitate use, an installation cylinder is designed in the inside of the bottle cap, one end of the installation cylinder is integrally connected with the inner bottom wall of the bottle cap, matcha powder is filled in the installation cylinder, the other end of the installation cylinder is slidably sleeved with a sealing cylinder, one end of the sealing cylinder is provided with a sealing plate, the outer edge of the sealing plate is sealingly connected with the end face of the sealing cylinder, and the connection part of the sealing plate and the sealing cylinder has a small thickness and is easy to be cut off.

[0005] The outer side wall of the sealing cylinder is provided with a ring-shaped lug, and the lug is used to fix the sealing cylinder through cooperation between the inner thread of the bottle cap.

[0006] When the bottle cap is screwed on the bottle body, the bottle mouth of the bottle body abuts against and tightly presses the end face of the sealing cylinder, and the inner diameter of the bottle mouth of the bottle body is greater than the outer diameter of the installation cylinder.

[0007] When drinking is needed, the bottle cap is continuously screwed, the sealing cylinder slides under the pushing of the bottle mouth of the bottle body, and then the relative displacement between the bottle body and the bottle cap is generated, the end of the installation cylinder pushes open the sealing plate, and the matcha powder in the installation cylinder falls into the bottle body and mixes with the water in the bottle body.

[0008] Meanwhile, a connecting block is integrally arranged on the sealing plate, one end of the connecting block is fixedly connected with the end face of the sealing cylinder, and the sealing plate is not easy to fall into the bottle body and pollute the solution in the bottle body when being pushed open through the connecting block.

[0009] For the above technical scheme, the inventors find that there are the following problems: because the sealing cylinder is fixed through cooperation between the lug on the outer side wall and the inner thread of the bottle cap, the sealing cylinder and the installation cylinder are in sliding cooperation, when the sealing cylinder is installed, the air between the installation cylinder and the sealing cylinder is compressed, the compressed air flows out from the gap between the installation cylinder and the sealing cylinder, and the matcha powder in the installation cylinder may overflow from the installation cylinder along with the airflow, if the bottle cap is directly installed on the bottle body subsequently, the overflowing matcha powder will fall into the water in the bottle body and pollute the water, therefore, an additional detection process and a cleaning process are needed to screen out and clean the bottle cap with material leakage, which increases the production cost. Utility Model Content

[0010] To address the issue that traditional matcha bottle caps may cause matcha powder inside the sealing cylinder to overflow and fall into the cap due to airflow during installation, requiring additional screening and cleaning processes and increasing production costs, this application provides a matcha bottle cap.

[0011] The technical solution for a matcha bottle cap provided in this application is as follows:

[0012] A matcha bottle cap, comprising:

[0013] The cap is used to attach to the bottle;

[0014] An installation cylinder, located inside the cover, is used to store materials;

[0015] A sealing cylinder is disposed at one end of the mounting cylinder;

[0016] A sealing plate is disposed at one end of the sealing cylinder and is used to cooperate with the sealing cylinder to seal the end of the mounting cylinder;

[0017] The sealing plate is connected to the end face of the sealing cylinder. The thickness of the connection between the sealing plate and the sealing cylinder is designed to be small so as to facilitate cutting. The inner wall of the sealing cylinder and the outer wall of the mounting cylinder are sealed and fixed by the cooperation of the annular protrusion and the annular groove.

[0018] Through the above technical solution, the sealing cylinder and the mounting cylinder are fixed together by the protrusion and the groove, so that the contact area between the sealing cylinder and the mounting cylinder is large when the sealing cylinder is initially inserted into the mounting cylinder, which makes the sealing performance between the sealing cylinder and the mounting cylinder better. During the process of the sealing cylinder being inserted into the mounting cylinder, the compressed air is not easy to leak from the sealing cylinder and the mounting cylinder, which in turn makes the material inside the mounting cylinder not easy to leak from the sealing cylinder and the mounting cylinder, thus improving the packaging quality and reducing the subsequent screening and cleaning costs.

[0019] Optionally, the protrusion is provided on the side wall of the mounting cylinder, and the groove is provided on the inner wall of the sealing cylinder.

[0020] Through the above technical solution, the protrusion strengthens the mounting cylinder, making the mounting cylinder less prone to vibration when the sealing cylinder is inserted into it. This, in turn, makes it less likely for the matcha powder inside the mounting cylinder to vibrate and leak during the installation of the sealing cylinder.

[0021] Optionally, the cross-section of the protrusion is an incomplete circle, and the cross-section of the groove is an incomplete circle that fits into the protrusion.

[0022] Optionally, the inner wall of the connection end between the sealing cylinder and the sealing plate is a smooth surface, the end face of the mounting cylinder is parallel to the plate surface of the sealing plate, and the end side wall of the mounting cylinder is in contact with the inner side wall of the sealing cylinder.

[0023] Optionally, a gap is provided between the end face of the mounting cylinder and the sealing plate.

[0024] Optionally, the end of the sealing cylinder is coaxially provided with an annular lug, and the outer edge of the lug opposite to the sealing plate is provided with a chamfer, which is used to cooperate with the sealing cylinder to be inserted into the cover.

[0025] Optionally, when the sealing cylinder is inserted into the mounting cylinder, a gap is provided between the lug and the inner wall of the cover.

[0026] Optionally, the side wall of the mounting cylinder facing away from the cover is smooth, and the inner wall of the sealing cylinder facing away from the sealing plate is smooth.

[0027] In summary, this application features a fixed connection between the sealing cylinder and the mounting cylinder formed by protrusions and grooves. This results in a larger contact area between the sealing cylinder and the mounting cylinder during the initial insertion of the sealing cylinder, leading to better sealing. During insertion, compressed air is less likely to leak between the sealing cylinder and the mounting cylinder, thus preventing material leakage from the mounting cylinder. This improves packaging quality, reduces subsequent screening and cleaning costs, and the protrusions on the mounting cylinder enhance its strength, making the mounting cylinder less prone to vibration when the sealing cylinder is inserted. Consequently, the matcha powder inside the mounting cylinder is less likely to leak due to vibration during installation. Attached Figure Description

[0034] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0035] This application discloses a matcha bottle cap, as shown in the embodiments below. Figure 1 , Figure 2 and Figure 3 It includes a cap 1 for mounting on a bottle, an mounting cylinder 2 coaxially and integrally disposed on the inner bottom wall of the cap 1, a sealing cylinder 3 disposed on the end of the mounting cylinder 2 away from the inner bottom wall of the cap 1, and a sealing plate 4 coaxially and fixedly mounted on the end of the sealing cylinder 3.

[0036] Reference Figure 2 and Figure 3 The cap 1 is integrally provided with internal threads for threaded connection with the beverage bottle.

[0037] Reference Figure 2 and Figure 3 The installation cylinder 2 is used to fill materials such as powder or solution. The sealing plate 4 and the sealing cylinder 3 are connected in a sealed manner, and the sealing cylinder 3 and the installation cylinder 2 are in a sealed fit. The material in the installation cylinder 2 is sealed by the fit between the sealing plate 4, the sealing cylinder 3 and the installation cylinder 2.

[0038] Reference Figure 2 and Figure 3 The outer wall of the mounting cylinder 2 has several annular protrusions, which are coaxial with the mounting cylinder 2 and spaced apart along the axial direction of the mounting cylinder 2. The inner wall of the sealing cylinder 3 has several annular grooves 31 that fit into the protrusions. When the sealing cylinder 3 is fitted onto the mounting cylinder 2 to seal the mounting cylinder 2, the protrusions fit into the grooves 31. The mounting cylinder 2 and the sealing cylinder 3 are fixed together by the fit between the protrusions and the grooves 31.

[0039] Reference Figure 2 and Figure 3 A retaining ring 32 is integrally formed on the end of the sealing cylinder 3 facing away from the cap body 1. The retaining ring 32 is located between the outer wall of the sealing cylinder 3 and the inner wall of the cap body 1. When the cap body 1 is tightened onto the bottle, the bottle mouth fits tightly against the retaining ring 32. The connection between the sealing plate 4 and the sealing cylinder 3 is designed to be relatively thin. When it is necessary to open the sealing plate 4, continue to tighten the cap body 1 in the tightening direction. The bottle mouth pushes the retaining ring 32 and the sealing cylinder 3 to move deeper into the cap body 1. Then, through the cooperation between the mounting cylinder 2 and the bottle mouth, the connection between the sealing plate 4 and the sealing cylinder 3 is cut off, and the sealing plate 4 is opened.

[0040] Reference Figure 2 andFigure 3 The end of the mounting cylinder 2 facing the sealing plate 4 is smooth and fits against the inner wall of the sealing cylinder 3, which makes the mounting cylinder 2 cut the sealing plate 4 more cleanly. It is less likely that there will be residue between the sealing plate 4 and the sealing cylinder 3, which would cause the material in the mounting cylinder 2 to be unable to flow smoothly.

[0041] Reference Figure 2 and Figure 3 When assembling the sealing cylinder 3, the sealing performance between the mounting cylinder 2 and the sealing cylinder 3 is high due to the cooperation between the multiple sets of protrusions and the grooves 31.

[0042] Reference Figure 3 and Figure 4 After the sealing cylinder 3 is assembled, a gap is provided between the sealing plate 4 and the mounting cylinder 2. The gap is used to compensate for the error during the sealing process, so that when the production line inserts the sealing cylinder 3 into the mounting cylinder 2, it is not easy for the sealing plate 4 to be directly cracked or pushed off due to the size error of the bottle cap or the error of the production line itself.

[0043] Reference Figure 2 and Figure 3 Meanwhile, compared to the traditional sealing method where the mounting cylinder 2 and the sealing cylinder 3 are sealed by the fit between their smooth surfaces, in the initial stage when the sealing cylinder 3 is inserted into the mounting cylinder 2, the contact area between the two is small and the sealing performance is still poor. The air squeezed by the sealing cylinder 3 and the mounting cylinder 2 will leak out from between the sealing cylinder 3 and the mounting cylinder 2. As a result, the material inside the mounting cylinder 2 may be sprayed out from between the mounting cylinder 2 and the sealing cylinder 3 under the influence of the airflow. This will cause the material to remain inside the cover 1, resulting in a poor sealing effect of the sealing cylinder 3.

[0044] Reference Figure 2 and Figure 3 Furthermore, if there is any leaked material remaining inside the cap 1 when it is installed on the bottle, the material can easily fall into the bottle and contaminate the liquid inside, causing the shelf life of the liquid inside the bottle to decrease. Therefore, the cap 1 with residual material inside needs to be removed and an additional cleaning process is required, or it can be discarded directly, both of which will incur additional costs.

[0045] Reference Figure 2 and Figure 3 In this embodiment, due to the cooperation between the protrusion and the groove 31, the initial contact area between the sealing cylinder 3 and the mounting cylinder 2 is large when the sealing cylinder 3 is inserted into the mounting cylinder 2, and the material inside the mounting cylinder 2 is not easy to leak from between the mounting cylinder 2 and the sealing cylinder 3.

[0046] Reference Figure 2 and Figure 3 Both the protrusion and the groove 31 have semi-circular cross-sections, which further expands the contact area between the mounting cylinder 2 and the sealing cylinder 3, resulting in better sealing performance.

[0047] Reference Figure 2 and Figure 3 The inner wall of the end of the sealing cylinder 3 facing the mounting cylinder 2 is also smooth, which facilitates the initial guidance of the sealing cylinder 3 during insertion and the initial fitting and fixing with the mounting cylinder 2.

[0048] Reference Figure 2 and Figure 3 The sealing cylinder 3 has an integrally formed annular lug 5 on the outer side wall of the end facing the mounting cylinder 2. The outer edge of the end of the lug 5 facing the inside of the cover body 1 has a chamfer 51. The internal thread of the cover body 1 protrudes from the inner wall of the cover body 1. The outer diameter of the lug 5 is the same as the minor diameter of the internal thread. Through the cooperation between the lug 5 and the internal thread of the cover body 1, the sealing cylinder 3 is more smoothly installed and sealed, and it is less likely to make mistakes.

[0049] After the installation cylinder 2 is installed, there is a gap between the lug 5 and the inner wall of the cover 1, so that when the cover 1 is turned to open the sealing plate 4, the lug 5 will not interfere with the opening of the sealing plate 4.

[0050] 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.
