Description

High barrier integral internal veterinary drug vials Technical Field

[0001] The invention relates to the technical field of veterinary drug packaging, in particular to a high-barrier integral inner-through veterinary drug vial. Background Art

[0002] Nowadays, animals are often treated with intravenous drips after they become ill. Therefore, people usually stockpile a batch of veterinary vials so that they can be used at any time for intravenous drip treatment. However, the animal treatment environment is relatively complex. To prevent veterinary vials from being damaged during treatment, veterinary vials are usually plastic bottles that are not easily damaged. However, existing plastic bottles have poor barrier properties such as oxygen and water insulation, which shortens the shelf life of veterinary vials.

[0003] In addition, the bottle caps of existing veterinary drug vials are usually combination caps. For example, Chinese utility model patent CN219398212U discloses a veterinary drug combination cap and a veterinary drug infusion container, which include an inner cap, a rubber stopper and an outer cap. The top of the inner cap is connected to an inner pull ring, which has a relatively complex structure, a cumbersome assembly process, and a high manufacturing cost. Moreover, since the inner pull ring cannot be restored once opened, the veterinary drug infusion container is fixed to the bottle body by a welding process after the bottle body is filled with the drug liquid, which makes the manufacturing process of the veterinary drug infusion container relatively complex, further increasing the manufacturing cost.

[0034] As shown in Figures 1 and 2, the high-barrier integral internal veterinary drug vial of this embodiment includes a cap 100 and a bottle body 200 with a top opening. The cap 100 includes an annular body 110, a receiving ring 120 formed by the inner ring wall of the annular body 110 extending axially in a direction away from the bottle body 200, a connecting ring 130 formed by the outer ring wall of the annular body 110 extending axially in a direction close to the bottle body 200, and a connecting ring 130 respectively extending toward the inner ring wall of the receiving ring 120 and the annular body 110. A sealing plug 140 is bonded and compatibly connected to the wall base of the bottle body 200, the connecting ring 130 is threadedly connected to the bottle body 200, a sealing step 210 extending radially outward is provided on the outer wall of the bottle body 200, and a sealing ring 150 is provided on the end of the connecting ring 130 facing the bottle body 200 for elastically abutting and sealing with the sealing step 210, a barrier layer 160 is provided on the outer wall of the cover body 100, and a barrier layer 2 220 is provided on the outer wall of the bottle body 200, and the cover body 100 is an integral structure. Specifically, the high-barrier integral internal veterinary drug vial of the present invention has a cover body 100 of an integral structure, and the annular main body 110, the containing ring 120, the connecting ring 130, the sealing plug 140 and the sealing ring 150 are integrally formed by injection molding. The structure is simple and no assembly is required, which greatly reduces the manufacturing cost. The veterinary drug vial is assembled by threading the connecting ring 130 and the bottle body 200, which greatly simplifies the assembly process. The sealing plug 140 and the top wall of the bottle body 200 are elastically abutted and sealed, and the sealing performance is good. The sealing ring 150 elastically contacts and seals the sealing step 210, and a barrier layer 1 160 is provided on the outer wall of the cover 100, and a barrier layer 2 220 is provided on the outer wall of the bottle body 200, so as to achieve full coverage of the veterinary drug vial, thereby improving the barrier property of the veterinary drug vial and effectively ensuring the quality of the liquid medicine. The drug can be dispensed by unscrewing the cover 100, and infusion therapy can be performed by screwing the cover 100 on. The operation process is simple and convenient. Compared with the existing technology, it has a long shelf life, low manufacturing cost, strong practicality, and is suitable for wide promotion and application. It should be understood that direct contact between the liquid medicine used in some veterinary drugs and the sealing plug 140 will not affect the quality of the liquid medicine. Optionally, a third barrier film is provided on the end face of the sealing plug 140 facing the bottle body 200, and the third barrier film prevents the sealing plug 140 from direct contact with the liquid medicine to improve the scope of application. Optionally, the injection molding process for the cap 100 of the high-barrier, integral, internal veterinary vial of this embodiment is as follows: first, the annular body 110, the receiving ring 120, and the connecting ring 130 are injection molded, and then the sealing plug 140 and the sealing ring 150 are injection molded separately. It should be understood that the specific injection molding process for the cap 100 is well known to those skilled in the art and will not be described in detail here.

[0035] In this embodiment, a first puncture groove 141 is recessed on the end surface of the sealing stopper 140 facing away from the bottle body 200. Specifically, the first puncture groove 141 reduces the axial thickness of the sealing stopper 140 to be punctured, thereby reducing the difficulty of needle puncture and facilitating needle puncture. Optionally, the first puncture groove 141 is arranged in a centrally located, conical shape to guide the needle during puncture.

[0036] In this embodiment, a second puncture groove 142 is recessed on the end surface of the sealing stopper 140 facing the bottle body 200. The second puncture groove 142 is coaxially arranged with the first puncture groove 141. Specifically, the coaxial arrangement of the second puncture groove 142 with the first puncture groove 141 further reduces the axial thickness of the sealing stopper 140 to be punctured, thereby reducing the difficulty of puncture by the injection needle and facilitating injection needle puncture.

[0037] In this embodiment, a first thread structure 131 is provided on the inner wall of the connecting ring 130, and a second thread structure 230 is provided on the outer wall of the bottle body 200 to be threadedly connected to the first thread structure 131. Specifically, the first thread structure 131 and the second thread structure 230 are threadedly connected to assemble the cap body 100 to the bottle body 200.

[0038] Example 2

[0039] As shown in Figures 3 and 4, this embodiment differs from Example 1 in that the cap 100 further includes a sealing film 121 welded to the end surface of the containment ring 120 facing away from the bottle body 200. Specifically, the sealing film 121 prevents the sealing plug 140 from contacting the external environment. During puncture by an injection needle, the sealing film 121 is first torn to expose the sealing plug 140, and then the sealing plug 140 is punctured to achieve drug infusion. Optionally, the sealing film 121 includes an easy-tear edge extending radially outward, and the easy-tear edge is provided with anti-slip grooves to increase friction. The easy-tear edge and anti-slip grooves facilitate the user's application of force to tear the sealing film 121.

[0040] Example 3

[0041] As shown in Figures 5-8, this embodiment differs from Example 1 in that the cap body 100 further includes a mounting ring 122 extending radially inward from the end of the receiving ring 120 facing away from the bottle body 200, and a sealing structure integrally injection-molded with the mounting ring 122. Specifically, the mounting ring 122 and the sealing structure cooperate to prevent contamination of the sealing plug 140 by the external environment, allowing the injection needle to puncture the sealing structure directly or first open the sealing structure to expose the sealing plug 140 before puncturing the sealing plug 140. Optionally, the sealing structure is a puncture portion 123, and the axial thickness of the puncture portion 123 is 0.3mm-0.5mm. The mounting ring 122 and the puncture portion 123 cooperate to prevent the sealing plug 140 from being contaminated by the external environment. The puncture portion 123 and the mounting ring 122 are molded together during the injection molding process. Therefore, when the thickness of the puncture portion 123 is between 0.3mm and 0.5mm, the puncture portion 123 is easy to injection mold and is easy to puncture with an injection needle. When the thickness of the puncture portion 123 is less than 0.3mm, it is easy to break during the injection molding process, and the injection molding difficulty is high. When the thickness of the puncture portion 123 is greater than 0.5mm, puncture is difficult. Preferably, the thickness of the puncture portion 123 is 0.4mm. Optionally, the sealing structure is a foldable cap 124, which is easy to break open to expose the sealing plug 140.

[0042] Example 4

[0043] As shown in Figures 9 and 10 , this embodiment differs from Example 1 in that the cap 100 further includes a pull ring 125 integrally molded with the end of the receiving ring 120 facing away from the bottle body 200. Specifically, the pull ring 125 prevents the sealing plug 140 from coming into contact with the external environment. During needle puncture, the pull ring 125 is first pulled off to expose the sealing plug 140, and then the sealing plug 140 is punctured to achieve drug infusion.

[0044] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
