FIG. 1 illustrates a contact lens package 100 of an embodiment. The contact lens package 100 includes a top plate 10, a receiving portion 20, a holding portion 30, a supporting portion 40, and a backing ring 50.
In one embodiment, the top plate 10 is substantially flat. The top plate 10 includes an upper surface 11 and an opposite lower surface 12. In one embodiment, the upper surface 11 are substantially parallel to the lower surface 12. An opening 13 is defined at an end of the top plate 10. The opening 13 penetrates through the upper surface 11 and lower surface 12.
FIGS. 1, 2, and 3 illustrate that the receiving portion 20 is located at an end of the top plate 10, and is aligned with the opening 13. The receiving portion 20 is configured to receive a contact lens (not shown) and a storage solution (not shown). The receiving portion 20 protrudes downward from the lower surface 12 of the top plate 10. In one embodiment, the receiving portion 20 is substantially bowl-shaped. A receiving groove 21 is defined in the receiving portion 20. In one embodiment, the receiving groove 21 corresponds to and is coupled with the opening 13. In one embodiment, the receiving portion 20 includes a bottom wall 22, a first side wall 23, a second side wall 24, a third side wall 25, and a fourth side wall 26. The first side wall 23, the third side wall 25, the second side wall 24, and the fourth side wall 26 are connect to each other in a written order, and are located between and connected to the bottom wall 22 and the top plate 10. The first side wall 23 is opposite to the second side wall 24. The third side wall 25 is opposite to the fourth side wall 26. The first side wall 23, the third side wall 25, the second side wall 24, the fourth side wall 26, and the bottom wall 21 cooperatively define the receiving groove 21. In one embodiment, each of the first side wall 23 and the second side wall 24 is substantially flat. Each of the third side wall 25 and the fourth side wall 26 is substantially arc-shaped. In one embodiment, each of an included angle between the first side wall 23 and the bottom wall 22 and an included angle between the second side wall 25 and the bottom wall 22 ranges from 100 to 140 degree. In one embodiment, the included angle between the first side wall 23 and the bottom wall 22 is greater than the included angle between the second side wall 25 and the bottom wall 22.
The holding portion 30 is located at another end of the top plate 10 opposite to the opening 13. The holding portion 30 protrudes downward from the top plate 10. In one embodiment, the holding portion 30 is substantially flat. An included angle between the holding portion 30 and the top plate 10 is not less than 90 degree. In one embodiment, the included angle between the holding portion 30 and the top plate 10 is greater than 90 degree. In one embodiment, an intersection of the holding portion 30 and the top plate 10 forms an arc-shaped transition extending from the holding portion 30 to the top plate 10. A holding surface 31 is defined at the intersection of the holding portion 30 and the top plate 10. In one embodiment, the holding surface 31 is an arc surface depressed from the intersection of the holding portion 30 and the top plate 10, thereby allowing a user to hold the contact lens package 100 more comfortably. A vertical height of the holding portion 30 can be greater than, equal to, or less than a vertical height of the receiving portion 20. In one embodiment, the vertical height of the holding portion 30 is substantially equal to the vertical height of the receiving portion 10.
The supporting portion 40 protrudes downward from the top plate 10 and surrounds the receiving portion 20. In one embodiment, the supporting portion 40 includes two first supporting arms 41 and a second supporting arm 42. The first supporting arms 41 are located on opposite sides of the receiving portion 20. The second supporting arm 42 is opposite to the holding portion 30. In one embodiment, the first supporting arms 41 and the second supporting arm 42 are spaced from each other. In one embodiment, a direction extending from the second supporting arm 42 to the holding portion 30 is substantially perpendicular to a direction extending from one of the first arm 41 to another first arm 41. Each of an included angle between each first supporting arm 41 and the top plate 10 and an included angle between the second supporting arm 41 and the top plate 10 is not less than 90 degree. In one embodiment, the included angles between each first supporting arm 41 and the top plate 10 and an included angle between the second supporting arm 41 and the top plate 10 are equal to 90 degree. In one embodiment, a vertical height of each first supporting arm 41 is substantially equal to a half of the vertical height of the holding portion 30. A vertical height of the second supporting arm 42 can be equal to or less than the vertical height of the holding portion 30.
In one embodiment, a width of the top plate 10 decreases along a direction from the first arms 41 to the holding portion 30 to form two smooth arc edges, thereby allowing the user to hold the contact lens package 100 more comfortably.
The backing ring 50 is located on the upper surface 11 of the top plate 10. The backing ring 50 corresponds to and surrounds the opening 13.
When two contact lens packages 100 are stacked, the top plate 10 of one contact lens package 100 is opposite to the top plate 10 of another contact lens package 100. The holding portion 30 of one contact lens package 100 contacts an inner side of the second supporting arm 42 of another contact lens package 100. A promote end of each first supporting arm 41 of one contact lens package 100 contacts a promote end of each first supporting arm 41 of another contact lens package 100. Therefore, a total volume of the two contact lens packages 100 after being stacked is decreased.
In other embodiment, the vertical height of each first supporting arm 41 and the vertical height of the second supporting arm 42 can be equal to the vertical height of the holding portion 30. In this embodiment, when the two contact lens packages 100 are stacked, the first supporting arms 41 of one contact lens package 100 can be staggered with the first supporting arms 41 of another contact lens package 100 and contact the lower surface of the top plate 10 of another contact lens package 100, therefore the total volume of the two contact lens packages 100 after being stacked can also be decreased.
In other embodiment, the contact lens package 100 further includes a cover film (not shown). The cover film is located on the backing ring 50 and seals the opening 13. The cover film is configured to prevent the contact lens and the care solution from spilling out of the receiving portion 20. In one embodiment, the cover film can be adhered to the backing ring 50.
