Description

Technical Field

[0001] The utility model relates to a medical aluminum cover and a medicine packaging container, belonging to the technical field of medicine packaging containers. Background Art

[0002] Medical aluminum caps are used to seal the liquid inlets and outlets of pharmaceutical packaging containers and are typically used in conjunction with sealing plugs. Since the packaging containers are sterilized with high-pressure steam after packaging, residual moisture often remains. This residual moisture can contaminate or breed bacteria between sterilization and use. Furthermore, during use, the upper end of the aluminum cap must be opened, and an infusion needle must be inserted through the sealing plug into the container. If this residual moisture permeates the puncture site of the sealing plug, it could potentially contaminate the needle or the medication inside the container.

[0003] In view of the above reasons, there is a need in the prior art to design a medical aluminum cover and a pharmaceutical packaging container that can prevent steam from entering the puncture site of the sealing plug. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a medical aluminum cover and a medicine packaging container.

[0005] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0006] A medical aluminum cap, comprising a container connecting portion and an upper end surface connected to the container connecting portion, wherein the upper end surface comprises an inclined surface, a sealing portion, a notch, and a tearing portion, which are sequentially arranged from the outside to the inside. The inclined surface is inclined toward the packaging container from the outside to the inside. The sealing portion is a full-circle groove extending toward the packaging container relative to the tearing portion. The tearing portion is also provided with a pull ring for tearing the tearing portion from the upper end surface.

[0007] When the aluminum cover is mounted on the container, the sealing portion is pressed against the sealing plug, and a sealed space located inside the sealing portion is formed between the upper surface of the sealing plug and the lower surface of the upper end surface.

[0008] In order to improve the sealing effect and protect the sealing plug, the sealing portion preferably adopts an arc groove extending toward the container.

[0009] In order to create a sealed space between the tearing portion and the upper end surface that can accommodate a certain amount of air and to improve the strength of the tearing portion, a transition arc surface is also provided on the outer edge of the tearing portion. The outer edge of the transition arc surface extends to the cutting groove. The transition arc surface is inclined toward the container from the center of the upper end surface to the outer edge, and the center of the transition arc surface bulges away from the container.

[0010] Preferably, a circular ring portion is provided between the sealing portion and the inclined surface, and when the tear portion is torn by the pull ring, the fulcrum position of the pull ring contacts the circular ring portion. The circular ring portion can be used to accommodate the pull ring and act as a fulcrum.

[0011] In order to improve the strength of the pull ring, it is preferably provided with reinforcing ribs on the outer edge of the pull ring. When the tearing portion is torn by the pull ring, the reinforcing ribs contact the circular ring portion. In this way, the pull ring only needs to be pulled up at a small angle to generate pulling force on the tearing portion.

[0012] In order to achieve the connection between the tearing portion and the pull ring under the premise of sealing, the tearing portion is preferably connected to the pull ring through a riveted protrusion, and the riveted protrusion and the tearing portion are an integrated sealing structure.

[0013] Furthermore, when the riveted protrusion is in an unriveted state, the riveted protrusion preferably adopts a hemispherical structure that bulges outward away from the bottle body, which facilitates the assembly of the pull ring; when the riveted protrusion is in a riveted state, the hemispherical structure is squeezed toward the cover body to form a riveted circular ring structure.

[0014] In order to ensure that there is a certain volume in the sealed space to accommodate air, when the aluminum cover is installed on the container, the tear portion does not contact the sealing plug.

[0015] Specifically, the inclined surface includes a first inclined surface and a second inclined surface sequentially connected from the outside to the inside, and an inclination angle of the first inclined surface relative to the upper end surface is greater than an inclination angle of the second inclined surface relative to the upper end surface.

[0016] In order to protect the pull ring, the highest point of the pull ring is preferably not higher than the height of the outer edge of the upper end surface.

[0017] A pharmaceutical packaging container comprises a sealing plug and a liquid inlet and outlet for liquid inlet and outlet, wherein the sealing plug is sealingly connected to the liquid inlet and outlet, and further comprises any one of the aforementioned medical aluminum caps, wherein the container connecting portion is connected to the container, and the sealing portion is squeezed onto the upper end surface of the sealing plug.

[0018] Beneficial effects achieved by the utility model:

[0019] Compared with the prior art, the present invention can isolate external steam by squeezing between the sealing portion and the sealing plug, and form a sealed cavity between the tearing portion and the upper surface of the sealing plug. In this way, during the high-pressure steam sterilization process, the pressure inside the sealed cavity resists the external steam pressure, preventing external steam from entering the puncture position on the upper surface of the sealing plug, thereby avoiding the problem of contamination caused by steam.

[0020] The inclined surface forms an inwardly concave structure on the upper end surface of the aluminum cover, which plays a certain protective role for the pull ring. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] like Figures 1 to 4 This embodiment discloses a medical aluminum cap, comprising a container connection portion 2 and an upper end surface connected to the container connection portion 2. The upper end surface is the sealing end surface of the aluminum cap. The upper end surface comprises, arranged in order from the outside to the inside, a bevel 7, a sealing portion 5, a notch 4, and a tearing portion 1. The "outside to inside" mentioned above refers to the direction from the outer edge (container connection portion 2) to the center of the upper end surface. The notch 4 is typically located on the outside of the upper end surface. The container connection portion 2 is used to connect to a liquid inlet and outlet 9.

[0031] The sealing portion 5 is a full-circle groove extending toward the packaging container relative to the tearing portion 1. The tearing portion 1 is also provided with a pull ring 3 for separating the tearing portion 1 from the upper end surface. The inclined surface 7 slopes from the outside to the inside toward the packaging container. In other words, the inclined surface 7 forms a concave structure on the entire upper end surface. The sealing portion 5, the groove 4, the tearing portion 1, and the pull ring 3 are located within this concave structure. The highest point of the pull ring 3 is generally no higher than the outer edge of the upper end surface. This outer edge of the upper end surface provides some protection for the inner pull ring 3, preventing it from being accidentally pulled up or damaged. A rounded corner 21 forms the transition between the container connecting portion 2 and the inclined surface 7.

[0032] The inclined surface 7 in this embodiment includes a first inclined surface 71 and a second inclined surface 72 connected sequentially from the outside to the inside. The inclination angle of the first inclined surface 71 relative to the upper end surface is greater than the inclination angle of the second inclined surface 72 relative to the upper end surface.

[0033] In this embodiment, the sealing portion 5 is an arc groove extending toward the container, that is, the radial cross section of the sealing portion 5 is an arc shape (including an ellipse). Figure 3 Compared with other extrusion structures, the arc structure can gradually improve the sealing effect of the sealing layer from the outside to the inside, and the arc structure can also avoid damage to the sealing plug during the pressurization process. In this embodiment, the entire aluminum cover can be compared to a cylinder. The radial direction mentioned in this embodiment refers to the direction parallel to the upper end surface, that is, Figure 4 The horizontal orientation of the view.

[0034] Combine Figures 2 to 5 : The outer edge of the tearing portion 1 is also provided with a transition arc surface 12 ( Figure 2 The oblique line area in the figure) is shown in FIG. 1 , and the outer edge of the transition arc surface 12 extends to the groove 4. The transition arc surface 12 is inclined toward the container from the center of the upper end face to the outer edge, and the center of the transition arc surface 12 is raised in the direction away from the container. A circular ring portion 6 is also provided between the sealing portion 5 and the inclined surface 7. It can be seen from the above description that the radial cross-section of the transition arc surface 12 is in the shape of a circular arc, and the tearing portion 1 is slightly higher than the circular ring portion 6 (extending in the direction of the original container). This has at least three advantages. First, the overall strength of the upper end face is improved by forming a non-planar structure, especially the strength of the tearing portion 1. When the tearing portion 1 is separated from the surrounding upper end face structure from the groove 4, the tearing portion 1 is not easily deformed, and it is conducive to the tearing of the upper end face from the groove 4. Second, when the aluminum cover is installed on the container, when the sealing portion 5 and the sealing plug 8 are tightly fitted to form a sealing structure, the tearing portion 1 and the upper end face of the sealing plug 8 can form a sealed space, that is, the tearing portion 1 does not contact the upper end face of the sealing plug 8. The above-mentioned sealed space is Figure 4In the A area in the figure, there is a certain amount of air in the sealed space. During the high-pressure sterilization process, the air in the sealed space expands due to heat, and a certain air pressure is formed inside. This air pressure can offset or partially offset the external steam pressure, preventing steam from penetrating into the above-mentioned sealed space through the sealing portion 5. Figure 4 Arrow B in the figure indicates the flow direction of the steam. The sealing portion 5 is usually made of rubber and has a certain elasticity, which facilitates the squeeze seal with the sealing portion 5. Third, the position of the annular portion 6 is lower than the tear portion 1, so that it can accommodate the pull ring 3.

[0035] A reinforcing rib 32 is also provided on the outer edge of the pull ring 3. When the tear portion 1 is torn through the pull ring 3, the fulcrum position of the pull ring 3 contacts the circular ring portion 6. When the tear portion 1 is torn through the pull ring 3, the reinforcing rib 32 contacts the circular ring portion 6. The pulling direction of the pull ring 3 can be referred to. Figure 4 Arrow C in the middle, when the pull ring 3 is pulled up along the direction C, a fulcrum can be formed at the opposite end of the pull ring 3 ( Figure 4 、 Figure 6 and Figure 7 The connection position between the pull ring 3 and the tear portion 1 is between the fulcrum and the pulled-up position. After the tear portion 1 is pulled open, the puncture position of the sealing plug 8 is exposed inside the tear portion 1.

[0036] In this embodiment, if Figure 6 and Figure 7 As shown: the reinforcing ribs 32 are preferably flange structures located on the two outer edges of the pull ring 3. The flange structure reduces the distance between the pull ring 3 and the annular portion 6, so that the pull ring 3 only needs to be pulled up at a small angle to generate tension on the tear portion 1.

[0037] The tear portion 1 is sealed integrally with the pull ring 3 via the riveted protrusion 11. This means that the riveted protrusion 11 does not create a path for steam leakage. It should be noted that, with the exception of the pull ring 3, the container connection portion 2 and the upper end surface of the medical aluminum cap of this embodiment are integrally stamped.

[0038] When the riveting protrusion 11 is in an unriveted state, the riveting protrusion 11 is a hemispherical structure convex outward away from the bottle body; Figure 5 As shown, when the riveted protrusion 11 is in the riveted state, the hemispherical structure is squeezed toward the cover body to form a riveted ring structure, which does not damage the sealing performance of the tear portion 1. The pull ring 3 is connected to the riveted protrusion 11 through the riveted portion 31 located inside the pull ring 3.

[0039] This embodiment also discloses a pharmaceutical packaging container comprising a sealing plug 8 and a liquid inlet and outlet port 9 for liquid inlet and outlet. The sealing plug 8 is sealingly connected to the liquid inlet and outlet port 9. The pharmaceutical packaging container also comprises the aforementioned medical aluminum cap of this embodiment, which is mounted on the liquid inlet and outlet port 9 via a container connecting portion 2 and is positioned externally to the sealing plug 8. The sealing portion 5 is pressed against the upper end surface of the sealing plug 8, and the tearing portion 1 corresponds to the puncture point on the upper surface of the sealing plug 8. The pharmaceutical packaging container typically refers to a medicine bottle, medicine packet, or medicine bag, but may also include other medical containers.

[0040] Compared with the prior art, this embodiment can isolate external steam by squeezing between the sealing portion 5 and the sealing plug 8, and form a sealed cavity between the tear portion 1 and the upper surface of the sealing plug 8. In this way, during the high-pressure steam sterilization process, the pressure inside the sealed cavity resists the external steam pressure, preventing external steam from entering the puncture position on the upper surface of the sealing plug 8, thereby avoiding the problem of contamination caused by steam.

[0041] The inclined surface 7 forms an inwardly concave structure on the upper end surface of the aluminum cover, which plays a certain protective role for the pull ring 3.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
