Goggle mask and method of manufacturing the same

Abstract

A goggle mask and a method of manufacturing the goggle mask are provided. The goggle mask includes a mask structure, a lens structure and a sealing glue material. The mask structure includes a skirt portion and a glass portion which is connected to the skirt portion. The glass portion includes a groove with a first inside surface, second inside surface and third inside surface. The lens structure includes a peripheral portion which is disposed in the groove and includes an annular surface facing the second inside surface. The front side surface faces the first inside surface, while the rear side surface faces the third inside surface. The sealing glue material is formed between the peripheral portion and the groove to provide a waterproof connection between the peripheral portion and the groove. Therefore, the manufacturing and / or the assembly of the goggle mask is advantageous.

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims priority to Taiwan Patent Application No. 107117803 filed on May 24, 2018, which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention provides a goggle mask and a method of manufacturing the same. In particular, it provides a goggle mask used for activities such as snorkeling or diving or the like and a method of manufacturing the same.Descriptions of the Related Art[0003]Goggle masks are used in water activities such as snorkeling or diving to cover the eyes and the nose thereof, thereby, preventing water (or substance in the water) from getting into the eyes and nose. A conventional goggle mask is mainly formed by combining a mask, a lens and a frame together. That is, the mask, the lens and the frame are respectively manufactured, then the lens is placed in the mask and the frame is tightly fixed onto the mask so that the lens is closel...

AI Technical Summary

Benefits of technology

The present invention provides a goggle mask that is easy to manufacture and assemble, which improves production performance. Additionally, the goggle mask includes a detachable frame structure, which increases its strength and appearance change.

Problems solved by technology

However, to tightly fix the frame onto the mask so that the lens and the mask are connected in a waterproof manner at each place therebetween, the frame itself requires many fixing structures such as clips.

Therefore, when the frame is manufactured by injection molding or the like, the design of the mold is relatively complicated.

Moreover, a relatively large force is required to tightly fix the frame onto the mask, so it is very inconvenient for a person to assemble the google mask.

Furthermore, the lens needs to be capable of bearing the force needed during the fixing process to avoid being broken, so the lens cannot be too thin.

Generally speaking, the aforesaid goggle mask is not advantageous in the design, manufacturing and assembly of the frame, so manufacturers have developed a goggle mask of another form in which a mask is directly formed on a lens.

However, the mask often unintendedly covers other portions of the lens when it covers the periphery of the lens (i.e., the so-called burr or overflow).

In addition to the drawbacks of improper mold design or process factors, the cause of the aforesaid situation further lies in the following factor: since a certain degree of tolerance (error) is allowed during the manufacturing, the thickness of each lens is not completely the same (e.g., with a difference of several tens of micrometers).

However, it is very likely that the mold does not abut against and cover the predetermined portion of the lens (i.e., the portion of the lens that should not be covered by the raw material of the mask) after the mold is assembled due to the difference in the thickness of the lens.

Therefore, after the raw material of the mask is injected into the cavity, the raw material not only covers the periphery of the lens, but also unintendedly covers other portions of the lens.

Because the burr (overflow) influences the appearance of the goggle mask and even blocks the lens, it is unacceptable for consumers.

However, this process is hard to be automatized and can only be accomplished by consuming a large amount of labor and time, which influences the production performance of the goggle mask.

Additionally, without the clamping of the frame, the bonding force between the lens and the mask of this kind of google mask is relatively small, so the waterproof connection will be influenced when the lens and the mask are separated by a user unintentionally or intentionally.

Moreover, without the frame, the appearance of this kind of goggle mask is monotonous and space of changing the design is limited.
