[0073] Example 1

[0074] like Figure 1 and Figure 2 As shown, the high barrier plastic vial cap of this embodiment is as follows Figure 1 and Figure 2As shown, in this embodiment, the bottle cap 200 includes a mounting body 210 and a sealing body 230 arranged on the mounting body 210 for holding and sealing the injection needle. A barrier layer 280 and a sealing portion 270 are arranged on the outer wall of the bottle cap 200. The sealing portion 270 is used to cooperate with the bottle body 100 to seal the gap between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100, so that the barrier layer 280 cooperates with the bottle body 100 having the barrier layer 130 on the outer wall to fully block and cover the outer wall of the vial. Specifically, the high barrier plastic vial cap of the utility model, the bottle cap 200 is connected to the bottle body 100 of the plastic vial to seal the bottle body 100 and realize the sealed packaging of the medicine. The sealing body 230 is arranged on the installation body 210 to tightly seal the syringe through the sealing body 230 to ensure the safety of medication. After the bottle cap 200 is installed on the bottle body 100, the sealing part 270 cooperates with the bottle body 100 to seal the gap between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100, thereby eliminating the gap between the outer wall of the bottle cap 200 and the bottle body 100. The gap between the outer wall connection parts is narrowed, so that the barrier layer 1 280 cooperates with the bottle body 100 with the barrier layer 2 130 on the outer wall to fully barrier and cover the outer wall of the vial, effectively improving the barrier property of the vial. This solution eliminates the deficiencies in the prior art through the coordinated cooperation of the sealing part 1 and the barrier layer 1 280, so that the vial sealed with the high-barrier plastic vial cap can improve the barrier property through the comprehensive barrier coverage of the barrier coating, thereby being suitable for high packaging requirements of medicines, having a wide range of applications, and being highly practical, and suitable for extensive promotion and application.

[0075] In this embodiment, the bottle cap 200 also includes a connection structure for connecting with the bottle body 100 and applying a force to the sealing part 270 to promote the sealing part 270 to cooperate and seal with the bottle body 100, and the connection structure is a clamping part for clamping and connecting with the bottle body 100. Specifically, the bottle cap 200 is clamped and connected with the bottle body 100 through the clamping part to fix the bottle cap 200 on the bottle body 100, and at the same time of the clamping connection, the reaction force brought by the clamping connection promotes the sealing part 270 to cooperate and seal with the bottle body 100, so as to eliminate the gap between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100 and provide structural support for the comprehensive barrier coverage of the vial. Optionally, when the bottle cap 200 is clamped and connected with the bottle body 100 through the clamping part, the sealing part 270 is synchronously sealed with the bottle body 100, so as to improve the sealing performance through the reaction force brought by the clamping connection. Optionally, in another embodiment, the connection structure is a threaded portion for threaded connection with the bottle body 100, and the resistance pressure brought by the threaded connection causes the sealing portion 270 to cooperate and seal with the bottle body 100, so as to provide structural support for eliminating the gap between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100 and the comprehensive barrier coverage of the vial.

[0076] like Figure 3 and Figure 4 As shown, the sealing part 1 270 is an elastic body for elastically cooperating with the bottle body 100 for sealing. Specifically, the elastic body and the bottle body 100 are elastically abutted and sealed to improve the sealing between the elastic body and the bottle body 100, prevent the external gas from penetrating from the gap between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100, and provide structural support for the comprehensive barrier coverage of the vial. Optionally, the sealing part 1 270 is an elastic body for elastically cooperating with the sealing part 2 110 for sealing.

[0077] In this embodiment, the sealing portion 270 is a sealing surface 271 disposed on the end surface of the bottle cap 200 facing the bottle body 100 and used to match the shape of the matching end surface of the bottle body 100 to form a surface-to-surface sealing fit with the bottle body 100 .

[0078] In the present embodiment, the bottle cap 200 also includes a plug-in structure for plugging and matching with the bottle body 100. Specifically, the bottle cap 200 is plugged and matched with the bottle body 100 through the plug-in structure, so that the bottle cap 200 and the bottle body 100 are connected. Optionally, the clamping portion is arranged on the plug-in structure, so that when plugging and matching, the connection is synchronously clamped, so as to facilitate assembly. Optionally, the plug-in structure includes a first ring portion 240 and a second ring portion 250 arranged at intervals on the installation body 210, and a sealing ring 260 for sealing with the upper end surface of the bottle body 100 arranged between the first ring portion 240 and the second ring portion 250. Optionally, the clamping portion is a clamping protrusion 251 convexly arranged on the inner wall of the second ring portion 250, and a clamping boss 120 that is clamped and matched with the clamping protrusion 251 is provided on the outer wall of the bottle body 100. Optionally, a freeze-drying groove 241 is provided on the first ring portion 240. Specifically, when the vial is used to contain freeze-dried drugs, the moisture of the freeze-dried drugs needs to evaporate during the freezing process. In the process of clamping the bottle cap 200 on the bottle body 100, the clamping protrusion 251 and the clamping boss 120 are in abutment with each other to limit the upward movement of the bottle mouth of the vial within a preset force, so that the vial is in a semi-closed state, and the internal moisture can evaporate through the freeze-drying groove 241. When all the moisture evaporates, the installation body 210 is pressed with a force greater than the preset force to completely compact the bottle cap 200, so that the upper end surface of the bottle body 100 and the sealing ring 260 are pressed against each other to achieve the sealing of the bottle mouth of the vial. Optionally, the sealing portion 1 270 and the second ring portion 250 are integrally formed by a double-material injection molding process.

[0079] In this embodiment, the bottle cap 200 also includes a sealing ring 260 arranged in the plug-in structure for abutting and sealing with the bottle body 100. Specifically, during the plug-in fitting, the sealing ring 260 and the bottle body 100 are abutted and sealed, thereby achieving a triple seal of the sealing body 230, the sealing part 1 270 and the sealing ring 260, achieving comprehensive barrier coverage while ensuring sealing. Optionally, during the plug-in fitting, the bottle cap 200 and the bottle body 100 are synchronously clamped and connected, so that the reaction force brought by the clamping connection can further ensure the internal sealing between the bottle cap 200 and the bottle body 100 through the sealing ring 260, and the external sealing between the bottle cap 200 and the bottle body 100 through the sealing part 1 270.

[0080] In this embodiment, the bottle cap 200 further includes a mounting portion 220 disposed on the mounting body 210, a mounting cavity provided in the mounting portion 220 for accommodating the sealing body 230, and a sealing assembly disposed on the mounting portion 220 for sealing the sealing body 230. Specifically, the mounting portion 220 forms a mounting cavity to accommodate the sealing body 230, and the sealing body 230 is sealed by the sealing assembly to prevent the sealing body 230 from affecting the storage quality of the medicine before use and contaminating the injection needle when using the medicine.

[0081] like Figure 3 and Figure 4 As shown, in this embodiment, the sealing assembly includes a first sealing structure 300 arranged on the first end of the mounting portion 220 for sealing the external opening of the mounting cavity and a second sealing structure 400 arranged on the second end of the mounting portion 220 for sealing the internal opening of the mounting cavity. Specifically, the first sealing structure 300 and the second sealing structure 400 are used to realize the double sealing of the inside and outside of the sealing body 230, so as to prevent the sealing body 230 from contaminating the medicine or the external environment from contaminating the sealing body 230. It should be understood that in this embodiment, the first end refers to the end facing away from the bottle body 100, and the second end refers to the end facing the bottle body 100. It should be understood that the internal opening of the mounting cavity refers to the opening that connects the mounting cavity with the inner cavity of the bottle body 100, and the internal opening of the mounting cavity is sealed to prevent the sealing body 230 from directly contacting the medicine in the bottle body 100. Optionally, in another embodiment, when the sealing body 230 is a film-coated rubber plug, the second sealing structure 400 may not be provided.

Specifically, during the injection molding process, the first end of the installation portion 220 is firstly injection molded axially upward to form an unbent pressing edge 510, and after the injection molding is completed, a hot pressing process is used to bend and form the pressing edge 510 to press the sealing body 230 and fix the sealing body 230 in the accommodating cavity, and during the hot pressing process, the base density of the pressing edge 510 is increased and closely fits with the first end face of the sealing body 230, so that the fixing is reliable.

[0084] like Figure 3 and Figure 4 As shown, in this embodiment, the second fixing structure 600 is a support edge 610 integrally injection-molded with the second end of the installation body 210 for supporting the sealing body 230. Specifically, the second end of the sealing body 230 is supported by the support edge 610 to cooperate with the pressing edge 510 to fix the sealing body 230.

[0085] like Figure 3 and Figure 4As shown, in this embodiment, a sinking portion 630 for increasing the distance between the sealing body 230 and the second sealing structure 400 is arranged on the second fixed structure 600. Specifically, by arranging the sinking portion 630 arranged in a ring shape on the supporting edge 610, the distance between the sealing body 230 and the second sealing structure 400 is increased through the sinking portion 630, so that the needle of the syringe has enough extension space to stretch and then puncture the second sealing structure 400, thereby greatly reducing the puncture resistance, minimizing or avoiding the generation of insoluble particles, and even if insoluble particles are generated, they will be blocked in the cavity space enclosed by the sinking portion 630 and the second sealing structure 400, and will not be brought into the bottle body 100. In the example, the second fixed structure 600 is provided with a sinking portion 630 for increasing the distance between the sealing body 230 and the second sealing structure 400.

[0086] like Figure 3 and Figure 4 As shown, in this embodiment, the first sealing structure 300 is a first sealing film 310 welded and attached to the end surface of the mounting body 210 facing away from the bottle body 100. Specifically, the first sealing film 310 is convenient for operators to open and thus facilitate syringe puncture.

[0087] like Figure 3 and Figure 4 As shown, in this embodiment, the second sealing structure 400 is a puncture portion 420 integrally injection molded with the lower end of the sinking portion 630. Specifically, the puncture portion 420 and the lower end of the sinking portion 630 are integrally injection molded, the sealing is reliable, the sealing body 230 is prevented from contacting with the drug to the greatest extent, and the compatibility with the drug is good.

[0088] like Figure 3 and Figure 4As shown, the high barrier plastic vial of the present embodiment comprises the above-mentioned high barrier plastic vial cap, and the vial further comprises a bottle body 100, a barrier layer 2 130 is arranged on the outer wall of the bottle body 100, a sealing portion 2 110 is arranged on the outer wall of the bottle body 100, and the sealing portion 2 110 is used for sealing in cooperation with the sealing portion 1 270, so that the barrier layer 1 280 and the barrier layer 2 130 cooperate to fully barrier and cover the outer wall of the vial. Specifically, the high barrier plastic vial of the utility model contains medicines through the bottle body 100, and the bottle cap 200 is connected to the bottle body 100 to seal the bottle body 100 to achieve sealed packaging of the medicines. The sealing body 230 is arranged on the mounting body 210 to tightly seal the syringe through the sealing body 230 to ensure the safety of medication. After the bottle cap 200 is installed on the bottle body 100, the sealing part 1 270 is synchronously sealed with the sealing part 2 110, thereby eliminating the gap between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100, that is, the barrier coating is formed on the vial. The outer wall of the bottle is complete and continuous, and at the same time, the barrier layer 1 280 and the barrier layer 2 130 cooperate to fully block and cover the outer wall of the vial, so as to maximize the barrier property of the vial and meet the barrier property requirements of the packaged medicine. Based on the original vial, this solution optimizes and improves the structure of the vial through the cooperation of the sealing part 1 270, the sealing part 2 110, the barrier layer 1 280 and the barrier layer 2 130, greatly reducing the manufacturing cost of the vial while improving the barrier property of the plastic vial. It is highly practical and suitable for wide promotion and application. Optionally, the sealing part 1 270 and the second ring part 250 are integrally formed by a double-material injection molding process. It should be understood that the double-material injection molding process is a well-known technology of those skilled in the art and will not be described in detail here. It should be understood that in another embodiment, the sealing part 1 270 and the second ring part 250 are split structures; or the sealing part 1 270 is a part of the second ring part 250. It should be understood that the sealing of the sealing part 1 270 and the sealing part 2 110 can also reduce the process difficulty and cost of forming the barrier layer 1 280 and the barrier layer 2 130, that is, the barrier layer 1 280 is first plated on the outer wall of the bottle cap 200, and then the bottle cap 200 and the bottle body 100 are assembled, and then the bottle cap 200 of the vial is facing downward to serve as a support base point for the overall external plating process to plate the barrier layer 2 130 on the outer wall of the bottle body 100. Compared with the existing bottle cap 200 and the bottle body 100, after the bottle cap 200 is assembled, the bottle cap 200 of the vial is first facing upward, the external plating is performed for the first time, and then the vial is turned over so that the bottle cap 200 of the vial faces downward, and then the external plating is performed for the second time, the external plating area is greatly reduced. It should be understood that the stronger the sealing performance between the sealing part 1 270 and the sealing part 2 110, the more structural support can be provided for the comprehensive barrier coverage of the vial by the barrier layer 1 280 and the barrier layer 2 130. It should be understood that if Figure 2As shown, after the sealing part 1 270 and the sealing part 2 110 are abutted and sealed, the portion of the outer wall of the bottle body 100 that is in contact with the external gas is evenly provided with the barrier layer 2 130, and the portion of the outer wall of the bottle body 100 that is not in contact with the external gas is shielded by the bottle cap 200, and under the action of the sealing part 1 270 and the sealing part 2 110, there is no gap between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100 at the connection, and then under the action of the barrier layer 1 280 and the barrier layer 2 130, the full barrier coverage of the vial can be achieved, that is, the sealing part 1 270, the sealing part 2 110, the barrier layer 1 280 and the barrier layer 2 130 cooperate to achieve full barrier coverage of the vial.

[0089] like Figure 3 and Figure 4 As shown, in this embodiment, the sealing part 1 270 is an abutting ring 1 arranged on the end of the bottle cap 200 facing the bottle body 100, and the sealing part 2 110 is an abutting ring 2 convexly arranged on the outer wall of the bottle body 100 for abutting and sealing with the abutting ring 1. Specifically, after the bottle cap 200 and the bottle body 100 are connected, the abutting ring 1 is synchronously abutted and sealed with the abutting ring 2, so as to eliminate the gap between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100 to the greatest extent through the abutting pressure, so that the barrier layer 1 280 and the barrier layer 2 130 are in contact and continuous on the outer wall of the plastic bottle, thereby fully blocking and covering the outer wall of the plastic bottle. Optionally, when the abutting ring 2 and the abutting ring 1 are in contact, the outer wall of the abutting ring 1 and the outer wall of the abutting ring 2 are in contact and continuous, thereby making the barrier coating completely continuous on the outer wall of the plastic bottle. It should be understood that the stronger the sealing performance between the abutting ring 1 and the abutting ring 2, the more structural support can be provided for the comprehensive barrier coverage of the plastic bottle by the barrier layer 1 280 and the barrier layer 2 130. It should be understood that the abutting end faces between the abutting ring 1 and the abutting ring 2 match each other to ensure good sealing performance after abutment. It should be understood that in this embodiment, the abutting end faces between the abutting ring 1 and the abutting ring 2 are arranged horizontally to achieve a horizontal abutting and fitting seal to reduce the difficulty of processing, while in other embodiments, the abutting end faces between the abutting ring 1 and the abutting ring 2 can be adjusted according to needs, such as a conical abutting and fitting seal or an arc abutting and fitting seal.

[0090] like Figure 3 and Figure 4As shown, in this embodiment, the sealing part 110 is an elastomer for elastically cooperating with the sealing part 1 270 to seal. Specifically, the sealing part 1 270 is elastically cooperating with the elastomer to seal, so as to improve the external sealing property of the cillin bottle and prevent the external gas from penetrating from the gap between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100. Optionally, the sealing part 1 270 and the sealing part 2 110 are both elastomers, so as to maximize the external sealing property of the cillin bottle through elastic deformation, prevent the external gas from penetrating from the gap between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100, and provide structural support for the comprehensive barrier coverage of the cillin bottle. It should be understood that when the sealing part 1 270 and the sealing part 2 110 are elastically abutted, under the action of elastic deformation, the uneven end surface caused by the lack of processing accuracy during the injection molding process of the sealing part 1 270 and the sealing part 2 110 can be compensated, thereby reducing the process difficulty and facilitating processing and manufacturing.

[0091] In this embodiment, the vial further includes anti-theft labels respectively bonded to the outer wall of the bottle cap 200 and the outer wall of the bottle body 100. Specifically, the anti-theft label identifies the use status of the vial and prevents the vial from being opened abnormally. It should be understood that if the vial of this solution is sealed with an anti-theft ring, a gap will be formed between the outer wall of the bottle cap 200 and the outer wall of the bottle body 100, and comprehensive barrier coverage cannot be achieved.
