Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, and in particular relates to a tropical blister pack aluminum for pharmaceutical packaging. Background Technology

[0002] In tropical and subtropical regions, the high temperature, high humidity, and abundance of insects place stringent demands on pharmaceutical packaging. Traditional aluminum blister packs for pharmaceuticals often employ a single structure, which has several drawbacks: firstly, their sealing performance is limited, making them unable to withstand long-term exposure to heat and moisture, easily leading to moisture absorption, oxidation, and deterioration of the medicine; secondly, the packaging material has poor tear resistance, meaning that even minor external forces can cause damage during transportation and use, exposing the medicine to the risk of contamination. Furthermore, existing aluminum blister packs cannot be resealed after opening; with repeated use, the packaging loses its protective function, significantly shortening the shelf life of the medicine.

[0003] Therefore, it is essential to invent a tropical blister pack aluminum for pharmaceutical packaging. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tropical blister pack aluminum for pharmaceutical packaging, including an adhesive frame, side ears, an adhesive frame, a curved ear, a handle ear, a sealing aluminum film, and a tear-resistant film. A curved ear is integrally fixed to a side ear at one end of the adhesive frame, and the curved ear is integrally fixed to one end of the adhesive frame. A handle ear is integrally fixed to the other end of the adhesive frame. A sealing aluminum film is integrally fixed to the outer surface of the adhesive frame, and a tear-resistant film is integrally fixed to the surface of the sealing aluminum film.

[0005] Preferably, the adhesive frame and the side ear are compositely fixed at the opening of the tablet packaging box. The lower surface of one end of the curved ear is compositely fixed with the side ear, while the lower surface of the other end is not compositely fixed with the side ear. It is integrally set with the adhesive frame, and the side ear can restrict the movement of the adhesive frame by bending itself.

[0006] Preferably, the outer surface of the adhesive frame is provided with a slope, and the inner surface of the adhesive frame is provided with an inner slope that matches the outer slope of the adhesive frame. Both the adhesive frame and the adhesive frame are rectangular frame structures.

[0007] Preferably, the inner inclined surface of the bonding frame is formed by applying PU removable adhesive to form an adhesive surface, and the sealing aluminum film fixed on the surface of the bonding frame is a composite aluminum film structure composed of PA film, AL film and VC adhesive layer.

[0008] Preferably, a tear-resistant film is laminated and fixed on the outer surface of the sealing aluminum film, i.e., the PA film surface, and the tear-resistant film has a diagonal frame structure.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This utility model's sealing aluminum film adopts a composite structure composed of PA film, AL film and VC adhesive layer, combined with PU removable adhesive surface, to form multiple sealing barriers, significantly improving water and oxygen barrier capabilities, effectively preventing medicines from getting damp and oxidized in tropical environments. Tests have shown that it reduces water vapor transmission rate and extends the shelf life of medicines.

[0011] The diagonal frame structure tear-resistant film composited on the outer surface of the sealing aluminum film of this utility model can effectively disperse stress and prevent crack propagation. Compared with traditional packaging, it improves tear resistance and can ensure the integrity of the packaging and protect the safety of medicines even during transportation compression or frequent opening.

[0012] This invention achieves flexible opening and closing and secure packaging through the combination of an adhesive frame, side ears, curved ears, and a handle. The curved side ears restrict the movement of the adhesive frame, the handle facilitates opening, and the removable PU adhesive supports repeated sealing, meeting the needs of patients for multiple medication retrievals while avoiding the risk of medication exposure and contamination.

[0013] Furthermore, the beveled design of the adhesive frame and bonding frame in this invention ensures a tight fit, enhances the overall structural stability, and prevents sealing failure due to material expansion and deformation in humid and hot environments. This structure is adaptable to various sizes of tablet packaging boxes, has strong versatility, and possesses promising market application prospects. Attached Figure Description

[0020] As attached Figure 1 To be continued Figure 2 As shown:

[0021] This utility model provides a tropical blister pack aluminum for pharmaceutical packaging, comprising an adhesive frame 1, side ears 2, an adhesive frame 3, curved ears 4, handle ears 5, a sealing aluminum film 6, and a tear-resistant film 7. The curved ears 4 are integrally fixed to the side ears 2 at one end of the adhesive frame 1. The curved ears 4 are integrally fixed to one end of the adhesive frame 3. The handle ears 5 are integrally fixed to the other end of the adhesive frame 3. The sealing aluminum film 6 is integrally fixed to the outer surface of the adhesive frame 3, and the tear-resistant film 7 is integrally fixed to the surface of the sealing aluminum film 6.

[0022] Furthermore, the adhesive frame 1 is injection molded from food-grade polypropylene (PP) and is bonded to the edge of the tablet packaging box opening via a hot-pressing process with the side ear 2. The curved ear 4 is made of elastic PET material, with one end firmly bonded to the upper surface of the side ear 2 using medical-grade acrylic adhesive, and the other end integrally molded with the adhesive frame 3. When the packaging needs to be opened, pulling the handle ear 5 moves the adhesive frame 3 upward, and the side ear 2 can elastically deform along its own curvature to form a limiting fulcrum; when closed, the side ear 2 resets and locks the adhesive frame 3 to prevent accidental opening. This structure has been tested and can withstand an accidental pulling force of 10N without failure.

[0023] Furthermore, the outer surface of the adhesive frame 1 has a sealing bevel with a 15° inclination angle, and the corresponding inner side of the adhesive frame 3 has an inner bevel with the same angle. Both are injection molded using a precision mold. The two rectangular frame structures, through the beveled fit, form a line contact sealing surface, which increases the contact pressure by 3 times compared to planar contact.

[0024] Furthermore, a removable PU adhesive layer is evenly applied to the inner bevel of the bonding frame 3 to form an adhesive surface. The sealing aluminum film 6 adopts a three-layer composite structure, which is made of PA film, AL film and VC adhesive layer through a dry lamination process.

[0025] Furthermore, the tear-resistant film 7 is made of biaxially oriented PET material, and a diagonal frame structure is laminated onto the PA film surface using a gravure printing process. The diagonal lines have an angle of 45° and a line width of 0.3mm, forming a diamond-shaped grid. The tear-resistant film 7 is bonded to the PA film using silicone pressure-sensitive adhesive, maintaining good adhesion within a temperature range of -20℃ to 60℃ without delamination.

[0026] The working principle is as follows: First, the tropical blister pack aluminum used in this medicine packaging achieves opening, closing, and sealing functions through the cooperation of structural components. The adhesive frame 1 and the side ear 2 are fixed to the opening of the tablet packaging box. The curved ear 4 connects the side ear 2 and the adhesive frame 3. When the handle ear 5 is pulled, the adhesive frame 3 moves upward, and the side ear 2 bends elastically to form a limiting fulcrum, ensuring stability during the opening process. When closing, the side ear 2 resets and locks the adhesive frame 3 to prevent accidental opening of the packaging.

[0027] Secondly, in terms of sealing performance, the adhesive frame 1 and the adhesive frame 3 are respectively provided with matching inclined sealing slopes. When the two are attached, they form a line contact sealing surface, which greatly increases the contact pressure and enhances the sealing effect compared with planar contact. At the same time, the PU removable adhesive layer on the inner slope of the adhesive frame 3 and the three-layer composite structure (PA film, AL film and VC adhesive layer) of the sealing aluminum film 6 work together to effectively block external moisture and oxygen and protect the medicine.

[0028] Finally, the ripstop film 7 is made of biaxially oriented PET material, and its surface has a diagonal frame diamond grid structure that can effectively disperse stress. When the packaging is subjected to external force, it prevents cracks from spreading and improves the tear resistance of the packaging during transportation and use. The silicone pressure-sensitive adhesive ensures that the ripstop film 7 is firmly bonded to the PA film under different temperature environments, maintaining structural stability.

[0029] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
