The present disclosure relates generally to a container and more specifically to a container that incorporates a convex lens in a base thereof to aid in viewing an object within the container.
Some sellers of products that are packaged in transparent jars desire a jar configuration that helps a user to view the products in the jars without opening the lid of the jar.
The present disclosure relates generally to a container that includes a convex lens. The container can be comprised of glass, plastic or a combination of glass and plastic. The lens can be formed with or fixed to a base of a container, embedded within the base of the container or molded within the base of the container. The properties of the lens depend on the height of the container, which determines the focal length for proper magnification. For example, a 2 inch (50.8 mm) tall container would use a 42 mm diameter double convex lens with a 68 mm focal length. In an embodiment, the lens can be substantially flat on one side while in another embodiment the lens can be curved on both sides. In an embodiment, the container can maintain a flat base with a natural curvature on the edges that enhance magnification or visibility of an object arranged in the container.
The disclosure generally relates to a jar with a magnifying convex lens integrated in the base of the jar. The lens has a focal length that is equal to or longer than the height of the jar, equal to or longer than the length of the sidewall of the jar, or equal to or longer than 80 percent of the length of the sidewall of the jar. This lens allows a user to look at a product located in the jar through the base of the jar and view a magnified image of the product or a portion of the product.
In use, when an object is placed in the container, the container is sealed with a covering (e.g., cap or lid) and rotated so that the bottom of the container can be viewed by an individual, the convex lens provides magnification to the contents inside. The cap or lid is a child-resistant-type cap or lid in some configurations.
With reference now to the drawings, embodiments of the container that includes a convex lens of the present disclosure will be described. In each of the configurations, a cap or lid is used to close the container. In some configurations, the lid or cap includes features that must be manipulated before the lid or cap is opened. These features make the lid or cap child resistant. The feature may be a cap or lid with two layers with the outer layer needing to be pushed down when turned to engage the inner layer or squeezed from the sides when turned to make the inner layer turned. Other type of child-resistant features also can be used.
A one-sided convex lens 112 (i.e., one side of the lens is flat and the other side of the lens is curved) extends from the base 102 within a cavity 114 of the container 100. The lens 112 can be molded within the base 102 of the container 100 with the lens 112 properties depending on the height of container 100, which determines the focal length for proper magnification of the object 116 arranged within the container 100.
As can be seen within the cavity 112 of the container 100 of
A convex lens 212 is embedded within the base 202 and does not extend within a cavity 214 of the container 200. The properties of the lens 212 depend on the height of container 200, which determines the focal length for proper magnification of an object 216 arranged within the container 200.

A one-sided convex lens 412 (i.e., one side of the lens is flat and the other side of the lens is curved) is embedded within the base 402 of the container 400. The lens 412 can be molded within the base 402 of the container 400 with the lens 412 properties depending on the height of container 400, which determines the focal length for proper magnification of the object 416 arranged within the container 400.
As can be seen within the cavity 412 of the container 400 of
A one-sided convex lens 112 (i.e., the outer side of the lens is flat and the inner side of the lens is curved) extends from the base 102 within a cavity 114 of the container 100. The lens 112 can be molded within the base 102 of the container 100 with the lens 112 properties depending on the height of container 100, which determines the focal length for proper magnification of the object or object or a portion of the object arranged within the container 100. In this configuration, the focal length is equal to or longer than the height of container 100 and is thus equal to or longer than 67 mm, equal to or longer than the height of sidewall 104 and is thus equal to or longer than 51.5 mm, or equal to or longer than 80 percent of the height of sidewall 104 and is thus equal to or longer than 41.2 mm.
