Abstract
Description
Technical Field
[0001] The present invention relates to a mask structure, and in particular to a mask for underwater activities, such as swimming goggles, diving or snorkeling masks, etc. Background Art
[0002] There are many styles of masks on the market, but for each style, in order to meet the cost, most of them can only be made into a common size to fit the face shapes of different people (including different ages, different races, and different genders). They are not comfortable to wear and the waterproof reliability is not high. In order to ensure waterproofness, users usually can only tighten the headband, but this action will greatly reduce the wearing comfort, and sometimes the mask will be more prone to leaks due to warping. If several versions of different sizes are made, although some problems can be solved, the mold cost will be greatly increased, and it may not really accurately meet personalized needs. Moreover, for the mask market where replacement is fast, it is not economical to make a mask style in multiple sizes.
[0003] In view of this, solving the above problems simultaneously or partially has become a unanimous goal of the industry. Summary of the invention
[0004] The main purpose of the present invention is to provide a mask structure, in which the face-contacting area of the waterproof skirt assembly is made of a material that can be repeatedly molded, such as a memory material, or a material that can be deformed due to temperature changes or pressure changes, so that when the user wears the mask, the waterproof skirt assembly can further follow the contour of the contact area and be shaped accordingly, thereby becoming a personalized mask specifically for the user. When the user needs to be changed, the temperature change and / or pressure change can be applied again, and when another user wears the mask again, the face-contacting part of the waterproof skirt assembly can follow the contour of the new contact area and be shaped again, so as to achieve the purpose of repeatedly deforming and repeatedly shaping the face-contacting part of the waterproof skirt assembly.
[0005] To achieve the above-mentioned purpose, the present invention provides a mask structure, comprising: a frame, a viewing window assembly having a peripheral edge, and a waterproof skirt assembly having a front portion and a face-contacting portion. The front portion and the peripheral edge of the viewing window assembly are embedded in the frame together, and the face-contacting portion extends backward from the front portion and has a circumferential contact area. The face-contacting portion has a first shape and is made of a re-moldable material; when a user puts on the mask through a fastening device, the face-contacting portion can be squeezed by the user's face and deformed into a second shape, so that the circumferential contact area can further fit the user's facial contour; and when the user takes off the mask, the face-contacting portion still maintains the second shape.
[0006] The re-moldable material may be a deformable material that is at least one of temperature-oriented and pressure-oriented.
[0007] The re-moldable material can change the face portion from the first shape to the second shape when subjected to a temperature between 40° C. and 110° C., and when cooled back to room temperature, the face portion can be fixed in the second shape.
[0008] The re-moldable material can change the face-contacting portion from a first shape to a second shape and be fixed in the second shape when the user wears the mask tightly and is subjected to pressure close to the user's face.
[0009] The re-shaping material may be a memory material or a material containing memory polyurethane (PU) foam.
[0010] The front portion and the face-attaching portion can be made of a flexible material with a hardness ranging from Shore A 20 to 80.
[0011] The material of the front portion may be an adhesive material.
[0012] The material of the front portion can also be selected from materials based on thermoplastic rubber (TPR), thermoplastic polyurethane (TPU), silicone rubber, polyvinyl chloride (PVC) or a combination thereof; the material of the face portion can be selected from materials based on thermoplastic elastomer (TPE), polyolefin elastomer (POE), ethylene vinyl acetate (EVA), silicone rubber or a combination thereof.
[0013] The front portion and the face portion may be made of different materials.
[0014] The front portion may be harder than the face portion.
[0015] In terms of technology, the front portion and the face portion can be integrally formed, and the frame portion and the waterproof skirt assembly can also be integrally formed. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] refer to Figure 1 and Figure 2 The structure of a mask 1 includes: a frame 10, a viewing window assembly 20 having a peripheral edge 21, and a waterproof skirt assembly 30 having a front portion 31 and a face-contacting portion 32. The front portion 31 and the peripheral edge 21 of the viewing window assembly 20 are embedded in the frame 10 together, and the face-contacting portion 32 extends backward from the front portion 31 and has a circumferential contact area 33. The face-contacting portion 32 has a first shape and is made of a re-moldable material; when a user (U) puts on the mask 1 through a fastening device 40, the face-contacting portion 32 can be squeezed by the face of the user (U) and deformed into a second shape, so that the circumferential contact area 33 can further fit the facial contour of the user (U); and when the user (U) takes off the mask 1, the face-contacting portion 32 still maintains the second shape. The fastening device 40 is usually disposed between two outer ends of the frame 10 or the waterproof skirt assembly 30 .
[0033] In terms of structure, the re-moldable material is a deformable material that is at least one of temperature-oriented and pressure-oriented. In terms of temperature-oriented deformation, when the face-adhering portion 32 is subjected to a temperature between 40°C and 110°C, for example, and the user (U) wears the mask 1 and the face-adhering portion 32 is against the face of the user (U), the face-adhering portion 32 can be changed from a first shape to a second shape, and when it returns to room temperature (for example, at about 25°C), the face-adhering portion 32 can be fixed in the second shape. In terms of pressure-oriented deformation, when the user (U) wears the mask tightly and is subjected to a pressure that is close to the face of the user (U) (for example, the thrust of the user (U) himself, the tension of the headband 40, or the water pressure faced after entering the water), the face-adhering portion 32 can be changed from a first shape to a second shape and fixed in the second shape. The two parameters of deformation oriented by temperature and pressure can be selected or considered simultaneously. The embodiments of deformation guided by temperature are not limited to the above-mentioned temperatures. The temperature setting can have different "deformation-temperature" ranges according to the properties of different materials. Even when certain materials are selected, when the user (U) wears the mask 1, it can be in contact with the skin surface of the user (U) with a certain temperature for a short period of time, or it can be in the outside weather with a higher temperature, the same deformation effect can be achieved. The purpose is to make the face-contacting portion 32 further deform along the face of the user (U) in contact, and the circumferential contact area 33 can be further extended along the facial contour of the user (U), so as to increase the waterproofness between the mask 1 and the face of the user (U), and at the same time increase the comfort of the user (U) wearing the mask 1. The facial contour in this embodiment refers to the eye socket area (U1) around the eye, such as Figure 1 As shown; in other embodiments, it may refer to other peripheral areas sufficient to cover the user's (U) eyes and nose, or the eyes, nose and mouth.
[0034] In terms of use, for example, thermoplastic elastomer (TPE) is used as the basis, or a better polyolefin elastomer (Polyolefin When the waterproof skirt assembly 30 is made of a material based on POE (Poly Elastomer), before use, the face-contacting portion 32 of the waterproof skirt assembly 30 has a first shape. At this time, the user (U) can first place the mask 1 in warm or hot water, for example, between 40°C and 110°C (or blow it with a hair dryer or a hot air gun; if you are at the beach in summer, you can directly contact the mask 1 with the hot beach environment or other heating modes). After a short period of time, for example, a few seconds to tens of seconds, it reaches a temperature that can be shaped. Then, the mask 1 is put on and pressed against the face, or tightened with a headband 40, so that the circumferential contact area 33 of the face-contacting portion 32 of the waterproof skirt assembly 30 can closely follow the facial contour of the user (U). At this time, the face-contacting portion 32 of the waterproof skirt assembly 30 will form a second shape, so that the circumferential contact area 33 better conforms to the facial contour of the user (U), that is, the purpose of shaping is achieved. In addition to increasing the fit between the mask 1 and the user (U), the original material can still maintain the comfort of contacting the skin. When the mask 1 is in use, if the ambient temperature is still at a high plastic temperature, the face-contacting portion 32 of the waterproof skirt assembly 30 will continue to dynamically flexibly fit the face of the user (U). When the temperature is lower than the plastic temperature, such as a relatively low room temperature, the face-contacting portion 32 of the waterproof skirt assembly 30 will be fixed. This mode is like a personalized mask for the user (U). If different users (U) want to use the mask, the above-mentioned heating and cooling steps can be repeated to repeatedly achieve the purpose of deformation and shaping.
[0035] The above-mentioned re-molding material may be a memory material or a material containing a memory material, such as a memory polyurethane (PU) foam. Alternatively, the front portion 31 and the face portion 32 of the waterproof skirt assembly 30 are made of a flexible material with a hardness between Shore A 20 and 80. Preferably, the material of the front portion 31 is selected from a material based on thermoplastic rubber (TPR), thermoplastic polyurethane (TPU), silicone rubber, polyvinylchloride (PVC) or a combination thereof; the material of the face portion 32 is selected from a material based on thermoplastic elastomer (TPE), polyolefin elastomer (POE), ethylene vinyl acetate (EVA), silicone rubber or a combination thereof. High Temperature Vulcanized Silicone Rubber (HTV Silicone Rubber) is a preferred material among silicone-based materials. The front portion 31 and the face portion 32 can be made of the same or different materials, preferably different materials, such as Figure 3A As shown. Preferably, the hardness of the front portion 31 is greater than that of the face portion 32. The front portion 31 can be made of adhesive material to serve as a good medium for connecting the face portion 32 and the frame 10. In terms of manufacturing, the front portion 31 and the face portion 32 can be integrally formed, such as Figure 3B The frame 10 and the waterproof skirt assembly 30 can be assembled in a waterproof inlay manner, or can be integrally formed, or even the frame 10 and the front portion 31 can be firstly injection molded, and then the face portion 32 can be combined with the frame 10 and the front portion 31 by a second injection molding, so that the integrity and waterproofness of the entire product are better.
[0036] The above-mentioned embodiments are only for example, and the attached drawings are only for swimming goggles as an example, that is, a frame is matched with two viewing windows separated on the left and right and two waterproof skirts separated on the left and right. The two viewing windows jointly define the viewing window assembly, and the two waterproof skirts jointly define the waterproof skirt assembly. However, any changes in any manner, for example, the face-attached part of the waterproof skirt assembly that can be repeatedly molded is used in other types of masks, such as diving, snorkeling, fishing, swimming training masks that only cover the eyes and nose (the mask has a closed or breathable structure), or full-face snorkeling masks that cover the eyes, nose and mouth (the viewing window assembly is a full-face covering type or only covers the eyes), etc., and the viewing window assembly is not limited whether it is a one-piece type or a left-right separated type, and all are intended to be protected by the present invention.
