Description

Technical Field

[0001] The present application relates to the technical field of blister packaging, and in particular to a contact lens packaging that is easy to open. Background Art

[0002] Blister packages are currently the most commonly used packaging for contact lenses. The blister packages include a container with a concave cavity and a removable flexible composite film that is sealed on the container. The container and the flexible composite film are sealed by pressurized heat sealing and then sterilized by high temperature and wet heat (there will be a pressure imbalance during the process) to ensure that the product complies with relevant hygiene regulations. However, if the firmness is not high, the package will burst or produce gaps that are difficult to detect, resulting in the risk of product scrapping or later storage.

[0003] The existing contact lens packaging boxes have to strengthen the heat-sealing strength of the seal to ensure product safety, which will cause other problems: the surface of the flexible composite film is smooth, and the flexible composite film is not easy to be held during the process of opening the package, making it difficult to open the package.

[0031] The present application embodiment discloses a contact lens package that is easy to open, referring to Figure 1 , Figure 2 and Figure 3 , including a support platform 1, a storage portion 2, a support portion 3, a lever member 4 and a flexible composite film 5. The support platform 1 is in the shape of a plate, and has a first surface 11 and a second surface 12. The support platform 1 is provided with a perforation 13 at one end away from the storage portion 2. The shape of the perforation 13 can be an ellipse, a circle, a rectangle, a polygon and other shapes when viewed from above, and the perforation 13 can accommodate the user's finger passing through. The storage portion 2 is connected to one end of the support platform 1. The storage portion 2 is a concave cavity structure, and the concave cavity is concave toward the second surface 12. The concave cavity is used to store contact lenses and sterile solutions.

[0032] The supporting platform 1, the storage part 2, the supporting part 3 and the lever member 4 are integrally injection molded with the same polypropylene material, which is convenient for production and manufacturing, and at the same time increases the structural strength of the contact lens package, making the contact lens package less susceptible to damage by external forces.

[0033] The support part 3 is vertically connected to the peripheral edge of the support platform 1, and the support part 3 faces the second surface 12. The height dimension of the support part 3 is greater than or equal to the depth dimension of the cavity of the storage part 2 to prevent the storage part 2 from being damaged by external compression.

[0034] The flexible composite film 5 is made of a flexible composite material. The shape of the flexible composite film 5 is adapted to the contour of the supporting platform 1. The flexible composite film 5 is arranged on the first surface 11. The flexible composite film 5 is sealed and connected to the supporting platform 1 by pressurized heat sealing.

[0035] The lever member 4 includes a gripping portion 41 and a lever portion 42 connected to the opposite side of the gripping portion 41. The gripping portion 41 is an elliptical structure and is disposed at the corresponding through hole 13 of the support platform 1. The lever portion 42 is an arc-shaped rod-shaped structure. One end of the lever portion 42 away from the gripping portion 41 is connected to the support platform 1 near the storage portion 2, and under the action of external tension, the lever portion 42 can be separated from the support platform 1. The lever member 4 is located on the first surface 11, and the flexible composite film 5 is heat-sealed on the side of the lever member 4 away from the first surface 11. The lever portion 42 includes at least two ends away from the gripping portion 41, and the end of the lever portion 42 away from the gripping portion 41 is not colinear with the gripping portion 41. When in use, the gripping portion 41 is acted on to push the gripping portion 41 outward, and a lever effect is formed through the lever portion 42 connected to the gripping portion 41 and the support platform 1, thereby driving the flexible composite film 5 to separate from the support platform 1; through the gripping portion 41 on the lever member 4, the surface roughness of the flexible composite film 5 is increased through the gripping portion 41, so that the flexible composite film 5 is not easy to slip when being pulled, which facilitates the flexible composite film 5 to be torn off from the support platform 1, thereby improving the user experience.

[0036] A sealing ring 6 is provided on the supporting platform 1 on the peripheral side corresponding to the opening of the receiving portion 2, and the sealing ring 6 is located on the first surface 11. In a high-pressure aseptic environment, the flexible composite film 5 is sealed and connected to the sealing ring 6 by pressurized hot melting to ensure that the contact lens packaging complies with hygiene regulations. The sealing ring 6 is connected to the flexible composite film 5 to reduce the connection area between the flexible composite film 5 and the supporting platform 1, which facilitates the flexible composite film 5 to be torn apart. The thickness of the lever member 4 is the same as that of the sealing ring 6, so that the surface of the flexible composite film 5 connected to the lever member 4 and the sealing ring 6 is flat, which is convenient for storage. The supporting platform 1 and the sealing ring 6 are integrally injection molded using the same polypropylene material, which is convenient for production and manufacturing.

[0037] The thickness of the lever member 4 is smaller than or equal to the height of the sealing ring 6 protruding from the first surface 11 .

[0038] The implementation principle of an easy-to-open contact lens package in the embodiment of the present application is: the contact lenses and sterile solution are accommodated in the storage part 2, and in a high-pressure sterile environment, one end of the flexible composite film 5 is sealed and connected to the sealing ring 6 by pressurized hot melting, and the end of the flexible composite film 5 away from the storage part 2 is connected to the lever member 4, and one end of the lever member 4 is connected to the position where the support platform 1 is opened into the storage part 2. The lever member 4 can be separated from the support platform 1 under the action of external pulling force, and the flexible composite film 5 can be easily removed through the lever member 4.

[0039] When in use, the lever member 4 is pushed outward through the perforation 13, and the lever member 4 and the supporting platform 1 form a lever effect, which acts on the holding portion 41, driving the flexible composite film 5 to separate from the opening side of the storage portion 2, holding the position of the lever member 4 corresponding to the flexible composite film 5, pulling the flexible composite film 5, the lever member 4 and the flexible composite film 5 are separated from the supporting platform 1 together, and the flexible composite film 5 is torn open; the lever member 4 increases the holding force on the flexible composite film 5, which facilitates the opening of the contact lens package.
