Description

Technical Field

[0001] This application relates to the field of bottle cap technology, and in particular to an injection molding method for NFC inside a bottle cap and a bottle cap manufactured by the method. Background Technology

[0002] With the increasing public awareness of health, the control of drug use is receiving more and more attention. Users not only need to follow the doctor's advice to take the medicine on time and in the prescribed dosage, but also need to understand the detailed instructions of the medicine through the instruction leaflet. Therefore, it is necessary to put the instruction leaflet on the medicine bottle.

[0003] Currently, staff print text on stickers or engrave words on the outer wall of stickers, and then stick the stickers to the outer wall of the medicine bottle. Users can obtain relevant information about the medicine through the text on the sticker and take the medicine according to the instructions on the sticker.

[0004] The inventor believes that some drugs have a long shelf life, and the above-mentioned method of attaching instructions to the outer wall of the medicine bottle is prone to wear and tear and becomes ineffective over time, so there is room for improvement. Summary of the Invention

[0005] To reduce wear and tear on the instruction manual on the outer wall of a medicine bottle and avoid the problem of the instruction manual becoming invalid, this application provides an injection molding method for NFC inside a bottle cap and a bottle cap manufactured by the method.

[0006] This application provides an injection molding method for NFC inside a bottle cap and a bottle cap manufactured by this method, which adopts the following technical solution:

[0007] An injection molding method for NFC inside a bottle cap includes the following steps:

[0008] Preparation of the NFC chip: Secure the connecting sleeve to the side wall of the NFC chip;

[0009] An NFC chip is fixed, and a plug rod is fixed to the inner wall of the mold. The end of the plug rod is inserted and fixed to the inner wall of the connecting sleeve. The NFC chip is located inside the inner cavity of the mold.

[0010] Casting: Injecting casting liquid into the inner cavity of the mold;

[0011] After demolding and allowing the casting liquid to cool and solidify, open the mold and separate the end of the plug rod from the inner wall of the connecting sleeve.

[0012] By adopting the above technical solution, during the production of medicine bottle caps, an NFC chip corresponding to the instruction manual content of the medicine in the bottle is pre-manufactured. The mold for injection molding the bottle cap is opened, and the NFC chip is inserted into the connector rod, suspending the NFC chip within the mold cavity. Workers inject casting liquid into the mold cavity through the casting hole. After the casting liquid cools, the mold is opened, and the end of the connector rod is pulled out from the inner wall of the connecting sleeve, injection molding the NFC chip into the bottle cap. Users can obtain the medicine instruction manual information by scanning the outer wall of the bottle cap. This method of concealing the carrier of the medicine instruction manual information within the bottle cap avoids external wear and tear, thereby reducing the possibility of the instruction manual becoming invalid.

[0013] Optionally, a molding shell is fixed on the inner wall of the mold, the inner wall of the molding shell is rounded, the molding shell is ring-shaped, and the plug rod passes through the molding shell.

[0014] By adopting the above technical solution, during the injection molding process, the casting liquid fills the molding shell. The molding shell is designed so that the inner wall of the bottle cap after molding has an integrally formed ring. According to the specifications of the medicine bottle, a molding shell that matches the bottle mouth is set on the inner wall of the mold. During the bottling process, the ring formed on the inner wall of the bottle cap abuts against the side wall of the bottle mouth, thereby improving the sealing performance of the medicine bottle.

[0015] Optionally, the central angle corresponding to the arc length of the cross section in the diameter direction of the molded shell is between 120 and 180 degrees.

[0016] By adopting the above technical solution, the arc length of the cross-section of the molded shell along its own diameter direction is limited. On the one hand, this facilitates the detachment of the molded shell during demolding, and on the other hand, it makes the annular ring on the inner wall of the bottle cap compatible with the mouth of medicine bottles of different shapes.

[0017] Optionally, a pull rod is slidably connected to the mold, a sliding hole is provided on the inner wall of the mold, a sliding piece is slidably connected to the inner wall of the sliding hole, the pull rod is fixedly connected to the side wall of the sliding piece, the plug rod is fixed to the side of the sliding piece away from the pull rod, and the side wall of the molded shell is fixedly connected to the side wall of the sliding piece.

[0018] By adopting the above technical solution, during the bottle cap formation process, the pull rod abuts against the sliding piece, restricting the sliding of the sliding piece. After standing for a period of time, the surface of the bottle cap has a certain hardness. At this time, the pull rod is pulled away from the inner cavity of the mold. The pull rod drives the sliding piece to slide, and the sliding piece drives the molding shell and the plug rod to move, so that the molding shell and the plug rod move a certain distance away from the bottle cap. The pull rod is pulled at regular intervals, so that the casting liquid flows between the plug rod and the NFC piece, completely sealing the NFC piece into the bottle cap, and making demolding easier.

[0019] Optionally, the outer wall of the pull rod is provided with an elastic element for returning the sliding piece to its original position. One end of the elastic element abuts against the inner wall of the sliding hole, and the other end abuts against the side wall of the sliding piece.

[0020] By adopting the above technical solution, during the pulling of the rod, the elastic element is compressed. After demolding, the rod is released, and the sliding piece slides to the edge of the sliding hole under the action of the elastic element's own rebound force. This supports the bottle cap during the bottle cap forming process, making the bottle cap forming more stable. The elastic element facilitates the return of the sliding piece.

[0021] Optionally, the plug rod is tapered, and the cross-sectional area of ​​the plug rod gradually increases from one end away from the part connected to the inner wall of the mold to the other end.

[0022] By adopting the above technical solution, the plug-in rod guides the mold opening process. By setting the plug-in rod into a conical shape, the resistance caused to the mold opening is reduced, thus facilitating demolding.

[0023] Optionally, the device includes a housing, with the NFC sheet encapsulated within the housing, and a sealing ring fixed to the inner wall of the housing, the sealing ring being adapted to the molded housing.

[0024] By adopting the above technical solution, the NFC chip is integrally molded into the shell to prevent wear on the NFC chip. The sealing ring is injection molded from the shell. After the staff puts the shell on the medicine bottle, the side wall of the sealing ring abuts against the side wall of the opening of the medicine bottle, thereby improving the sealing performance of the medicine bottle.

[0025] Optionally, an inner cover is fixed to the inner wall of the outer shell, and a snap-fit ​​hole is provided on the side wall of the inner cover, and the sealing ring is snapped and fixed to the snap-fit ​​hole.

[0026] By adopting the above technical solution, the staff inserts the sealing ring into the snap-fit ​​hole and fixes the inner cap to the outer shell by riveting. During the drug bottling process, the inner cap is wrapped around the outer wall of the bottle mouth. The inner cap increases the contact area between the bottle cap and the bottle, thus making the fixation between the bottle cap and the bottle more stable.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Pre-fabricate NFC chips corresponding to the medications in the medicine bottle, and input the medication's instruction information into the NFC chips. During the bottle cap manufacturing process, the NFC chips are integrally molded into the cap using injection molding, reducing the risk of damage from external objects and preventing the instruction manuals from becoming invalid over time. Users can access the instruction manual content by scanning the bottle cap, providing convenience for users.

[0029] 2. During the injection molding process, the connecting sleeve is placed on the outer wall of the plug rod. With the support of the plug rod, the NFC sheet is supported into the inner cavity of the mold. The operator pours the casting liquid into the inner cavity of the mold through the pouring hole on the mold. After the casting liquid cools and is demolded, the NFC sheet is integrally formed into the bottle cap. The casting process is simple and convenient.

[0030] 3. During the bottle cap molding process, the staff can slowly pull the rod away from the inner cavity of the mold to separate the plug rod from the connecting sleeve. The space between the plug rod and the NFC is filled with casting liquid. After the bottle cap cools and solidifies, the NFC sheet is completely sealed inside the bottle cap, reducing the possibility of damage to the NFC sheet during the use of medicine bottles in daily life, and making it easier for staff to demold.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] Example 1:

[0039] An injection molding method for NFC inside a bottle cap also includes the following steps: (Refer to...) Figure 1The injection mold for the bottle cap includes a first mold 2 and a second mold 3. The pouring hole of the mold is opened on the second mold 3. The operator first installs the injection mold for the bottle cap on the platform, opens the mold, and sets the insertion rod 5 on the inner wall of the side of the first mold 2 facing the second mold 3. When the first mold 2 and the second mold 3 are merged, the insertion rod 5 is located in the inner cavity formed by the first mold 2 and the second mold 3.

[0040] Reference Figure 1 and Figure 2 According to the instructions for the medicine in the bottle, the contents of the instructions are entered into the NFC chip 1. The user can obtain the medicine information by scanning the NFC chip 1. The operator welds a fixed connecting sleeve 4 to the side wall of the NFC chip 1. In this application, the connecting sleeve 4 is preferably ring-shaped. Before the bottle cap is injected, the robot picks up the NFC chip 1 and puts the connecting sleeve 4 onto the end of the plug rod 5 away from the first mold 2, merging the first mold 2 and the second mold 3. With the support of the plug rod 5, the NFC chip 1 is located in the cavity formed by the first mold 2 and the second mold 3, and the NFC chip 1 is in a suspended state.

[0041] Reference Figure 1 The first mold 2 has a sliding hole 8 on the side facing the second mold 3. A sliding piece 9 is slidably connected to the inner wall of the sliding hole 8. The shape of the cavity formed by the sliding piece 9, the first mold 2, and the second mold 3 is the same as the shape of the bottle cap. A through hole is opened on the outer wall of the first mold 2, which is connected to the inner cavity of the first mold 2. A pull rod 7 is slidably connected to the inner wall of the through hole. One end of the pull rod 7 located in the inner cavity of the first mold 2 is welded and fixed to the side wall of the sliding piece 9, and the other end of the pull rod 7 is located outside the first mold 2. When the operator pulls the pull rod 7, it causes the sliding piece 9 to slide in the sliding hole 8.

[0042] Reference Figure 2 The outer wall of the pull rod 7 is provided with an elastic element 10 for returning the sliding piece 9 to its original position. In this application, the elastic element 10 is preferably a spring. One end of the elastic element 10 abuts against the side wall of the sliding piece 9, and the other end abuts against the inner wall of the first mold 2. Under normal conditions, the elastic element 10 is in a compressed state. Under the action of the elastic element 10's own rebound force, the sliding piece 9 slides to the edge position of the sliding hole 8, making the injection molding process of the mold more stable. During the pulling of the pull rod 7, the sliding piece 9 slides. After the pull rod 7 is released, under the action of the elastic element 10's own rebound force, the sliding piece 9 slides back to the edge position of the sliding hole 8.

[0043] Reference Figure 1 and Figure 2The connector 5 is fixed to the sliding piece 9 on the side facing the second mold 3 by welding. In this application, the connector 5 is truncated cone-shaped, and the cross-sectional area of ​​the connector 5 gradually increases from the end away from the first mold 2 to the end closer to the first mold 2. Before injection molding the bottle cap, the operator supports the NFC piece 1 in the cavity formed by the connecting sleeve 4 and the connector 5.

[0044] Reference Figure 2 A molding shell 6 is welded and fixed to the side of the sliding plate 9 facing the second mold 3. In this application, the overall appearance of the molding shell 6 is preferably set as a ring. The side of the molding shell 6 facing the second mold 3 is open. The cross-sectional shape of the molding shell 6 along the diameter direction is arc-shaped. In this application, the central angle corresponding to the arc line of the cross-section along the diameter direction of the molding shell 6 is in the range of 120-180 degrees. The setting of the molding shell 6 makes a circular protrusion formed on the inner wall of the injection-molded bottle cap. Limiting the opening angle of the molding shell 6 reduces the contact area between the molding shell 6 and the casting liquid, which facilitates demolding after molding.

[0045] Reference Figure 2 After supporting the NFC chip 1 inside the cavities of the first mold 2 and the second mold 3, the molds are closed. Casting liquid is injected into the cavity formed by the first mold 2 and the second mold 3 through the casting hole on the second mold 3, so that the casting liquid fills the mold cavity formed by the first mold 2 and the second mold 3. After standing for a period of time, once the outer wall of the bottle cap has formed, the pulling rod 7 is pulled. The pulling rod 7 causes the end of the sliding piece 9 to slide out of the connecting sleeve 4. The unformed casting liquid in the inner layer of the bottle cap flows into the connecting sleeve 4. After the bottle cap cools and forms, the mold is opened, and the first mold 2 and the second mold 3 are separated, completing the production of the bottle cap.

[0046] The implementation method of Embodiment 1 of this application: Refer to Figure 3 Prepare an NFC sheet 1 suitable for the corresponding medicine bottle. Weld a connecting sleeve 4 to the side wall of the NFC sheet 1. Insert the NFC sheet 1 into the end of the insertion rod 5 through the connecting sleeve 4. Inject casting liquid into the inner cavity of the mold through the casting hole on the second mold 3. After the surface of the formed bottle cap has a certain hardness, slowly pull the pulling rod 7 to drive the insertion rod 5 to disengage from the connecting sleeve 4. The unformed molten casting liquid inside the bottle cap flows into the connecting sleeve 4 to seal the NFC sheet 1. Finally, after the bottle cap cools down, demold it to complete the casting of the bottle cap.

[0047] Example 2:

[0048] An NFC bottle cap, reference Figure 2 and Figure 4The device includes an outer shell 11, which is injection molded using the same injection molding method as the NFC injection molding method described in Embodiment 1. A sealing ring 12 is integrally formed on the inner wall of the outer shell 11. The sealing ring 12 is formed by molding the inner cavity of the shell 6 during the injection molding process of the bottle cap in Embodiment 1. After the operator places the outer shell 11 onto the opening of the medicine bottle, the side wall of the sealing ring 12 abuts against the outer wall of the bottle opening, reducing the gap between the outer shell 11 and the outer wall of the bottle opening, thereby improving the sealing performance of the medicine bottle.

[0049] Reference Figure 4 An inner cover 13 is riveted to the inner wall of the outer shell 11. A snap-fit ​​hole 14 is provided on the outer wall of the inner cover 13, located in the middle of the inner cover 13. The outer shell 11 and the inner cover 13 are coaxially arranged. A sealing ring 12 is located inside the snap-fit ​​hole 14. In this application, the inner cover 13 is preferably made of aluminum. After the staff fills the medicine into the medicine bottle, they press the inner cover 13 to wrap around the outer wall of the bottle opening. At this time, the side wall of the sealing ring 12 abuts against the side wall of the bottle cap, thus completing the packaging of the medicine.

[0050] Reference Figure 5 An NFC chip 1 is fixed on the inner wall of the outer shell 11 by the casting method described in Embodiment 1. The NFC chip 1 contains detailed information about the drug. Users can obtain the corresponding information about the drug by scanning the outer shell 11.

[0051] In Embodiment 2 of this application, the implementation principle of an NFC bottle cap is as follows: The inner cap 13 is deformed by pressing, pressing it against the outer wall of the bottle neck. Under the pull of the inner cap 13, the outer shell 11 is pressed onto the bottle. The side wall of the sealing ring 12 abuts against the outer wall of the bottle cap, completing the encapsulation of the medicine. When a user needs to obtain information about the medicine in the bottle, they scan the outer shell 11, and the information in the NFC chip 1 is presented to the user. The user can then obtain relevant information about the medicine in the bottle through the information in the NFC chip 1. The NFC chip 1 is integrally formed in the outer shell 11, reducing the possibility of damage to the medicine's instructions and thus reducing the problem of contract invalidation.

[0052] 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.
