Description

Technical Field

[0001] This utility model belongs to the field of medical liquid packaging technology, and in particular relates to an anti-theft packaging for contrast agents. Background Technology

[0002] Currently, medical liquid packaging generally adopts a three-piece structure consisting of a bottle body, a sealed inner stopper, and an outer tamper-evident cap. The tamper-evident cap primarily indicates whether the packaging has been opened for the first time, while the sealed inner stopper bears the core function of preventing liquid leakage and maintaining sterility. However, this traditional structure exposes two significant problems in practical use: Firstly, because the sealed inner stopper needs to fit tightly with the bottle opening, when a user unscrews or breaks off the tamper-evident cap, the torque or prying force applied to the cap can easily be transmitted to the inner stopper through friction, causing the inner stopper to be accidentally pulled out. Once the non-sterile outer surface of the inner stopper comes into contact with the bottle opening or is exposed to air during opening, it will cause irreversible primary contamination of the liquid inside the bottle.

[0018] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the anti-theft packaging for contrast agents proposed in this utility model. The advantages and features of this utility model will become clearer from the following description and claims.

[0019] See Figures 1 to 7 In one embodiment, a contrast agent anti-theft packaging includes a bottle body 1, a sealed inner plug 2, a first anti-theft cap 3, and a second anti-theft cap 4.

[0020] The bottle body 1 includes a bottle mouth 101 and a first external thread 102 arranged on the bottle mouth 101. The sealing inner plug 2 is installed on the bottle mouth 101 of the bottle body 1.

[0021] The first tamper-evident cap 3 is threadedly connected to the first external thread 102. The top of the first tamper-evident cap 3 has a through-hole, and the first tamper-evident cap 3 is configured to press against at least partially sealing the inner plug 2 at the bottle mouth 101. The second tamper-evident cap 4 is openable and connected to the first tamper-evident cap 3, covering the through-hole (i.e., preventing exposure between the through-holes), and a process gap is provided between the second tamper-evident cap 4 and the first tamper-evident cap 3 to connect the through-hole.

[0022] In this embodiment, a first external thread 102 is provided on the bottle body 1, a sealing inner plug 2 is provided at the bottle mouth 101, and a combined first anti-theft cap 3 and second anti-theft cap 4 are provided. The first anti-theft cap 3 is connected to the bottle body 1 through the first external thread 102, and the second anti-theft cap 4 can be opened to connect to the first anti-theft cap 3 and cover the top of the first anti-theft cap 3 to achieve the combined connection. A through-hole is provided at the top of the first anti-theft cap 3, and at least part of the sealing inner plug 2 is pressed against the bottle mouth 101 by the first anti-theft cap 3. In this embodiment, both the first anti-theft cap 3 and the second anti-theft cap 4 can indicate whether the packaging has been opened for the first time. In use, only the second anti-theft cap 4 needs to be opened, and the sealing inner plug 2 can be pierced through the through-hole to take out the liquid from the bottle body 1. During the opening process, the first anti-theft cap 3 remains stationary, and no part comes into contact with the sealing inner plug 2. During use, the sealing inner plug 2 is always pressed tightly by the first anti-theft cap 3, thereby effectively protecting the liquid in the bottle from contamination and leakage, and effectively avoiding the risk of secondary contamination.

[0023] Furthermore, in this embodiment, a process gap with a through-hole is provided between the first anti-theft cover 3 and the second anti-theft cover 4. Since the contrast agent anti-theft packaging needs to be sterilized by high temperature wet capping after production, water vapor will penetrate through the process gap to the top of the sealed inner plug 2 to achieve sterilization. At the same time, the threaded connection of the second anti-theft cover 4 can also protect the top of the sealed inner plug 2 from contamination at room temperature, thus playing a protective role.

[0024] The specific structure of the anti-theft packaging for contrast agents in this embodiment is further explained below: In this embodiment, the openable connection between the second anti-theft cover 4 and the first anti-theft cover 3 can be a threaded connection, a snap-fit ​​connection, an interference fit connection, or a connection point connection, etc. There is no specific limitation here, as long as it can realize the connection between the two and reopen them.

[0025] In this embodiment, the aforementioned sealing inner plug 2 may specifically include an embedded section 201 and an extended section connected together. The embedded section 201 is sealed and embedded in the inner ring of the bottle mouth 101 (i.e., it is used for interference fitting into the bottle mouth 101 and sealingly fitting with the inner ring wall surface of the bottle mouth 101). The extended section includes an annular extension section 202 with a diameter larger than that of the embedded section 201. That is, the annular extension section 202 is formed by extending outward and is located above the annular upper end face of the bottle mouth 101. The annular extension section 202 is pressed against the bottle mouth 101 by a clamping ring 304 on the inner side wall of the first anti-theft cover 3. That is, the gap between the clamping ring 304 on the first anti-theft cover 3 and the bottle mouth 101 is maintained by the threaded connection between the first anti-theft cover 3 and the first external thread 102, so that the annular extension section 202 is pressed within the gap.

[0026] Furthermore, to facilitate puncture and liquid outflow, the embedded section 201 may be provided with a hollow through cavity, and the extended section is provided with a blind hole that opens downward and connects to the hollow through cavity. The solid part between the bottom surface of the blind hole and the top surface of the extended section is a puncture layer 203 for puncturing and discharging liquid. In use, it is only necessary to puncture the puncture layer 203 at the thinnest part of the sealed inner plug 2 to achieve communication with the internal space of the bottle body 1.

[0027] In this embodiment, the first anti-theft cover 3 includes a first cover body and a first anti-theft ring 306. The top surface of the first cover body is provided with a through opening, and the first anti-theft ring 306 is connected to the first cover body through a plurality of first connection points 308.

[0028] Furthermore, the first anti-theft ring 306 is provided with a plurality of spaced-apart strip openings 3061, and the bottle body 1 is provided with a plurality of bottle buckles 103 corresponding to the strip openings 3061. The bottle buckles 103 are configured to at least partially extend into the strip openings 3061. When the first anti-theft cap 3 is opened, the upward force and circumferential rotation force generated by the threaded connection at the first cap body are transmitted to the first anti-theft ring 306 through the first connection point 308. At this time, the interference contact between the bottle buckles 103 and the strip openings 3061 on the first anti-theft ring 306 provides a force to prevent the first anti-theft ring 306 from moving upward and circumferentially. When this force exceeds the strength of the first connection point 308, it will break, thereby indicating whether the first anti-theft cap 3 has been opened for the first time.

[0029] Further, the first cover body may specifically include a first annular body 301 and a second annular body 302 connected vertically. The outer side wall of the first annular body 301 is provided with a second external thread 303, and the upper opening of the first annular body 301 is a through opening. The inner side wall of the second annular body 302 is provided with a first internal thread 307 corresponding to the first external thread 102, and the lower end face of the second annular body 302 is connected to the first anti-theft ring 306 through a plurality of first connection points 308. The aforementioned clamping ring 304 may specifically be an extension ring formed radially inward on the inner ring surface of the first annular body 301 and / or the second annular body 302.

[0030] Furthermore, an annular recess 2021 can be provided on the top surface of the aforementioned annular extension 202, and a corresponding annular protrusion 3041 can be provided on the lower end surface of the clamping ring 304. The annular protrusion 3041 is used to extend into and press into the annular recess 2021 after assembly to form a line seal.

[0031] In this embodiment, to prevent the first connection point 308 from breaking due to excessive deformation caused by compression during the packaging production and assembly process, the surface of the first anti-theft ring 306 facing the first cover body (second annular body 302) is provided with a plurality of first support points 309, or the surface of the first cover body facing the first anti-theft ring 306 is provided with a plurality of first support points 309. By providing the first support points 309, when the first anti-theft ring 306 moves towards the first cover body, it can be abutted by the first support points 309, maintaining the gap between them, thereby keeping the first support points 309 within the allowable deformation range.

[0032] In this embodiment, the second anti-theft cover 4 may specifically include a second cover body 401 and a second anti-theft ring 402. The inner sidewall of the second cover body 401 is provided with a second internal thread 403 corresponding to the second external thread 303, and the second anti-theft ring 402 is connected to the second cover body 401 through a plurality of second connection points 404. Among them, a process gap is formed between the top surface of the inner cavity of the second cover body 401 and the top end of the first anti-theft cover 3 (that is, between the top surface of the inner cavity of the second cover body 401 and the top end of the first annular body 301).

[0033] Furthermore, the inner wall of the second anti-theft ring 402 is provided with a first annular protrusion 305, and the outer wall of the first anti-theft cover 3 is provided with a second annular protrusion 4021 for engaging with the first annular protrusion 305. That is, after assembly, the second annular protrusion 4021 is positioned above the first annular protrusion 305. When the second anti-theft cover 4 is opened, the upward force and circumferential rotation force generated by the threaded connection of the second cover body 401 are transmitted to the second anti-theft ring 402 through the second connection point 404. At this time, the interference contact between the second annular protrusion 4021 and the first annular protrusion 305 provides a force that prevents the second anti-theft ring 402 from moving upward and circumferentially. When this force exceeds the strength of the second connection point 404, it will break, thereby indicating whether the second anti-theft cover 4 has been opened for the first time.

[0034] Furthermore, to prevent excessive deformation and breakage of the second connection point 404 due to compression during packaging production and assembly, the second anti-theft ring 402 has several second support points 405 on its surface facing the second cover body 401, or the second cover body 401 has several second support points 405 on its surface facing the second anti-theft ring 402. The second support points 405 ensure that when the second anti-theft ring 402 moves towards the second cover body 401, it can be abutted by the second support points 405, maintaining the gap between them and keeping the second support points 405 within the allowable deformation range.

[0035] In this embodiment of the contrast agent anti-theft packaging, the first anti-theft cap 3 has a first anti-theft ring 306. When the bottle body 1 and the first anti-theft cap 3 are assembled, the bottle buckle 103 and the first anti-theft ring 306 of the first anti-theft cap 3 form a self-locking mechanism. At this time, if the first anti-theft cap 3 is rotated, the first connection point 308 will be destroyed, the first anti-theft ring 306 will fall off, and the anti-theft function will be realized.

[0036] The second anti-theft cover 4 has a second anti-theft ring 402. When the second anti-theft cover 4 and the first anti-theft cover 3 are assembled, the second anti-theft ring 402 of the second anti-theft cover 4 and the first anti-theft cover 3 form a self-locking mechanism. If the second anti-theft cover 4 is rotated, the second connection point 404 will be destroyed, the second anti-theft ring 402 will fall off, and the anti-theft function will be realized.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
