Manufacturing Method for 3D Solid Type Dental Mask {Manufacturing Method for 3D Solid Type Dental Mask}

The present invention relates to a method of manufacturing a 3D three-dimensional dental mask, and more particularly, a 3D three-dimensional dental mask capable of solving consumer complaints by partially changing the structure of a commercial dental mask so that the mask body does not adhere to the skin. It relates to a manufacturing method.

In general, a mask covers the mouth and nose of a user in order to protect a worker's respiratory system in a dusty or dusty workplace, etc., and plays a role of filtering harmful substances in the atmosphere.

These masks are used to protect users or people around them from various diseases transmitted through the respiratory tract, and in recent years, many people wear masks even on a regular basis in order to protect the respiratory system from environmental pollution, yellow dust and fine dust. In particular, recently, a mask equipped with a high-quality filter capable of blocking droplets has been widely used as a disease spread by spreading a virus by a droplet component generated in a person's mouth or nose, such as Corona 19, is spreading.

However, since the mask equipped with the high-quality filter is thick, it is inconvenient to use it in summer. Accordingly, in summer, a dental mask used for medical purposes is worn instead of a mask equipped with a high-quality filter such as KF94 or KF80.

As shown in FIG. 5, the dental mask has a planar shape, and a plurality of unfolding guide portions are provided on the mask body so that the mask body extends up and down by the unfolding guide portion when worn.

However, due to the flat structure of the dental mask described above, the inner surface is inevitably adhered to the wearer's face part, which makes it difficult to breathe or talk smoothly, and it is difficult to get loose or make-up, so there is an inconvenience of having to fix the make-up when removing the mask. In addition, there is a problem that can cause skin troubles due to direct contact with the skin.

On the other hand, as a result of researching the prior art related to the present invention, several patent documents were searched, and these are as follows.

Patent Document 1 discloses a face member having a bent portion formed at a portion covering the nose and having an edge following the curve of the face and a fixing member formed of an adhesive detachable to the human body surface along the inner rim of the face member as a size that covers the nose and mouth of the human body. It includes, and discloses a disposable mask in which the earring disappears and the adhesion with the face is increased, which is convenient, and the movement of the lower jaw is free.

Patent Document 2 is a mask body; An expansion guide portion provided on the mask body to guide the mask body to be unfolded or folded; A shape-maintaining member provided on the mask body and maintaining a deformed and deformed state when at least one of the upper and lower portions of the mask body is in close contact with the user's skin, and thus the upper or lower portion of the mask body is in close contact with the user's skin; And a ball contact guide member provided on both side edges of the mask body and in close contact with the user's ball so as to close gaps between the edges of both sides of the mask body when worn, and both side edges of the mask body on which the ball contact guide member is provided are provided at the edges of the mask body. A rounding part is provided concavely in the center, and the spreading guide part is made of a stacked structure, but is provided symmetrically with respect to the center of the length direction of the mask body. Since the central portion is stacked at the highest position, even if the mask body is unfolded in the vertical direction, a disposable medical round mask is disclosed that effectively blocks viruses and harmful substances by eliminating gaps in the area in contact with the user's cheeks regardless of the shape of the face. .

The terms used in the present invention are terms defined in consideration of functions in the present invention, and since these may vary according to the intention or custom of users or operators, the definitions of these terms correspond to the technical matters of the present invention. And should be interpreted as a concept.

In addition, the embodiments of the present invention do not limit the scope of the present invention, but are merely exemplary matters of the elements presented in the claims of the present invention, and are included in the technical idea throughout the specification of the present invention. This is an embodiment including a component that can be substituted as an equivalent in the component.

In addition, optional terms in the following embodiments are used to distinguish one component from other components, and the component is not limited by the terms.

Accordingly, in describing the present invention, detailed descriptions of related known technologies that may unnecessarily obscure the subject matter of the present invention will be omitted.

For explaining a preferred embodiment of the present invention, FIG. 1 is a configuration diagram showing a 3D three-dimensional dental mask according to the present invention, FIG. 2 is a side view of a 3D three-dimensional dental mask according to the present invention, and FIG. 3 is This is a reference diagram showing the appearance of the 3D three-dimensional dental mask during distribution. And, Figure 4 is a process diagram for explaining a 3D three-dimensional dental mask manufacturing method according to the present invention.

3D three-dimensional dental mask according to the present invention, as shown in Figs. 1 to 3, a mask body 10 provided with an unfolding guide portion 11 to be folded or unfolded, and the end of the unfolding guide portion 11 In addition to being fixed, a ball contact portion 12 that closes both ends of the mask body 10 to the user's ball, and is provided on the upper side of the mask body 10 to maintain a deformed and deformed state when wearing a mask. Thus, the nose piece portion 14 that makes the upper end of the mask body 10 in close contact with the user's nose and face, the lower end contact portion 15 provided at the lower end of the mask body 10, and the mask body ( It consists of including an ear band 20 provided on each side of the wearer's ear 10).

Here, the ball contact portion 12 is formed to have a length shorter than the upper and lower lengths of the mask body 10 so that the inner surface of the mask body 10 does not contact the wearer's face when worn. That is, the ball contact portion 12 is formed to have a length of about 1/2 to 2/3 of the upper and lower lengths of the mask body 10. This means that if the length of the ball contact part 12 is less than 1/2 of the upper and lower length of the mask body 10, pain may occur due to the short length or external air may be introduced through the ball contact part 12 This is because when the length of the ball contact portion 12 exceeds 2/3 of the upper and lower lengths of the mask body 10, it is difficult to implement a three-dimensional shape.

To this end, the middle portion of the ball contact portion 12 is cut in a V shape toward the inside and then sealed by welding to form a suture line 13. At this time, in order to form the suture line 13, instead of cutting the middle part of the ball contact part 12 in a V shape, the cut part in the V shape when unfolded by cutting both ends of the folded part obliquely in a state of being folded in the vertical direction It is desirable to make it appear.

And, the mask body 10, like a dental mask of various structures, may be made of a three-ply structure of a lining, a filter, and a waterproof surface, and a two-ply structure of a filter and a waterproof surface, or a single-ply structure having a waterproof function and a filtration function. It can also be made of a structure.

It is preferable that the 3D three-dimensional dental mask of the present invention is packaged and distributed in a folded state, as shown in FIG. 3. This is because, when packaging in a 3D state, the size of the packaging increases, which increases packaging costs and distribution costs.

In the 3D three-dimensional dental mask of the present invention configured as described above, the length of the ball contact portion is shorter than the upper and lower lengths of the mask body, so when worn, the mask body swells forward, which does not adhere to the face of the face on the inner side of the mask body. This makes breathing easier, and no loosening or makeup is applied to the inner surface of the mask body, so there is no need to fix the makeup, and skin troubles caused by contact between the mask body and the face skin are prevented.

On the other hand, the 3D three-dimensional dental mask manufacturing method of the present invention includes the steps of preparing a known dental mask, as shown in FIG. 4, and cutting both sides of the dental mask in a V shape, but in a state where the dental mask is folded in the vertical direction. It comprises a step of cutting both ends of the folded portion obliquely and the step of sealing the incision by welding.

For reference, when manufacturing a 3D three-dimensional dental mask using a 175×120 mm dental mask, fold the dental mask up and down and cut it into 40 mm inward and 30 mm downwards of the folded part when unfolded. The V-shaped incision is formed, and the cut is welded as it is folded to form a suture line.

Although described and illustrated in connection with some embodiments for exemplifying the technical idea of the present invention, the present invention is not limited to the configuration and operation as described above, and the scope of the technical idea described in the description of the invention It will be well understood by those skilled in the art that a number of changes and modifications can be made to the present invention without departing from it. Accordingly, all such appropriate changes and modifications and equivalents should be considered to be within the scope of the present invention.
