Description

Contact lens packaging structure

The present invention relates to a contact lens, and more particularly to a contact lens package structure.

The proportion of modern people's myopia is getting higher and higher, and the wearing of glasses often makes many myopia people think that it is not beautiful enough. Therefore, the number of myopias wearing contact lenses is gradually increasing.

Contact lenses are generally classified into long-wearing contact lenses and disposable (eg, daily or weekly throwing, bi-weekly throwing, etc.) contact lenses. Because long-wearing contact lenses tend to cause the wearer's eyes to be infected with proteins, dirt and other sediments, causing some diseases on the eyes, most ophthalmologists recommend the use of disposable contact lenses to effectively prevent eye diseases.

Disposable contact lenses are typically packaged in a contact lens package. A typical contact lens package mainly comprises a hard-shell container for accommodating a contact lens, and an aluminum foil for sealing the opening of the hard-shell container.

However, the above-described invisible eye package is often limited by the shape limitation of the hard case container, and is not advantageous for the user to carry. Specifically, the hard-shell container of the package is generally a hemispherical cup body, which is bound to have a certain thickness. Therefore, if placed in a user's pocket, it is liable to cause discomfort and cause inconvenience and trouble in carrying.

In view of the above, one aspect of the present invention provides a contact lens packaging structure, the purpose of which is to facilitate carrying by a user to reduce the discomfort caused by the conventional hard-shell container.

In order to achieve the above object, in accordance with an embodiment of the present invention, a contact lens package structure includes a flexible packaging material and a contact lens. The flexible packaging material is bent to surround an accommodating space. The contact lens is placed in the accommodating space.

According to another embodiment of the present invention, a contact lens packaging structure includes a first flexible packaging material, a second flexible packaging material, and a contact lens. The first flexible packaging material and the second flexible packaging material together form an accommodating space. The contact lens is placed in the accommodating space.

With the above embodiments, the present invention can utilize a single or two sheets of flexible packaging material to form an accommodating space for accommodating a contact lens. Since the flexible packaging material itself has flexible material properties, its shape can be slightly changed with external force, so the thickness of the flexible packaging material can be reduced to be harder than the conventional one as long as the accommodation space is just enough to accommodate the contact lens. The shell container is thinner and is convenient for the user to carry. In addition, since the shape of the flexible packaging material can be changed, the shape can be changed with the shape of the pocket when placed in a pocket, thereby eliminating the discomfort caused by the hemispherical hard-shell container in the conventional contact lens package.

The above description is only for explaining the problems to be solved by the present invention, the technical means for solving the problems, the effects thereof, and the like, and the specific details of the present invention will be described in detail in the following embodiments and related drawings.

The embodiments of the present invention are disclosed in the following drawings, and for the purpose of clarity However, it should be understood by those skilled in the art that the details of the invention are not essential to the details of the invention.
