The present invention relates to a face shield for eating and drinking that allows eating and drinking while wearing the face shield.

Conventionally, as a face shield, an attachment band is attached to the upper end of a transparent flexible shield member, and by attaching the attachment band around the head, the flexible shield member covers the entire face of the wearer S. (For example, see Patent Document 1).

Furthermore, there is a device that allows eating and drinking by rotating a transparent shield member rotatably attached to a main body frame that can be mounted on the head in an overhead direction (for example, see Patent Document 2). .

Japanese Patent Application Publication No. 2005-287561 Japanese Patent Application Publication No. 2015-205105

However, in the face shield of Patent Document 1, the distance between the flexible shield member and the face is short and it is not possible to eat or drink while wearing it, so it is necessary to remove the face shield each time to eat or drink. , cannot prevent droplets from dispersing while eating or drinking. Therefore, in order to make it possible to eat and drink while wearing the flexible shield member, if the distance between the flexible shield member and the face is increased in order to increase the space between the flexible shield member and the face, the distance between the flexible shield member and the face may be increased. Due to the increase in moment force due to the increased distance from the attachment part, twisting occurs in the attachment band, causing the lower end of the flexible shield member to approach the face, causing a gap between the flexible shield member and the face. There is a problem in that it is difficult to create a good space where people can eat and drink.

Furthermore, in the face shield of Patent Document 2, it is possible to eat and drink while wearing the face shield by rotating and lifting the shield member overhead; however, as in Patent Document 1, the shield member Since the distance between the face and the face is short, it is not possible to eat or drink with the shield member down. Therefore, if the distance between the shield member and the face is increased in order to widen the space between the shield member and the face in order to enable eating and drinking with the shield member lowered, the distance between the shield member and the attachment part may be increased. Due to the increase in moment force due to the increase of The problem is that it is difficult.

In other words, with the face shields of Cited Documents 1 and 2, it is not possible to eat or drink while wearing the shield or with the shield member down, and it is possible to eat or drink while wearing the shield or with the shield member down. Since it is also difficult to create a space, there is a problem in that it is not possible to effectively prevent droplets from scattering during eating and drinking.

The present invention was made in view of these problems, and an object of the present invention is to provide a face shield for eating and drinking that can effectively prevent the scattering of droplets during eating and drinking.

EMBODIMENT OF THE INVENTION The form for implementing the face shield for eating and drinking which concerns on this invention is demonstrated below based on an Example.

FIG. 1 is a diagram showing the wearing state in which the face shield 1 for eating and drinking according to the present embodiment is worn by a wearer S, and FIG. It is a figure showing the 1st shield film 3 and the 2nd shield film 4 which constitute.

As shown in FIGS. 1 and 2, the face shield 1 for eating and drinking according to the present embodiment is mainly curved downward along the ear so that it can be worn on the ear of the wearer S. The ear hook part 21 serves as the attachment part of the ear hook 21, and the overhang part 22 that extends from the temporal position of the wearer S to the front face position when the ear hook part 21 is worn on the ear (the upper side of the page indicated by the dashed-dotted line in FIG. 2) The mounting frame 2 is a resin-molded rod-shaped body having an arcuate shape when viewed from above; A band-shaped belt with a predetermined width (8 cm, which is a length corresponding to about half the vertical length of an adult head) that can cover the front region K of the mouth of the wearer S (see Fig. 2) by being attached to the The space L formed between the first shield film 3 made of a rectangular highly transparent film and the lower surface of the overhang part 22 and the face of the wearer S by being attached to the lower surface of the overhang part 22. It is composed of a second shield film 4 made of a highly transparent film shaped like a fan that almost closes the shield.

As shown in FIGS. 1 and 2, the mounting frame 2 of this embodiment has two parts for rotatably attaching the first shield film 3 to predetermined positions near the ear hook part 21 of the overhang part 22. A first mounting protrusion 23 is formed, and four second mounting protrusions 24 for immovably fixing the second shield film 4 are formed on the lower surface of the overhang 22 at approximately the same intervals. ing.

In addition, as shown in FIGS. 1 and 2, the mounting frame 2 of this embodiment has an arc apex 22' that is the farthest part of the overhang 22 farthest from the face of the wearer S. A nose frame portion 25 is formed so as to straddle the apex portion 22' and the wearer's S nose.

As shown in FIG. 1, the nose frame portion 25 has a shape that extends upward from the mounting frame 2 in the overhang portion 22 and then extends toward the nose of the wearer S, that is, extends upward. The shape of the nose frame is curved and approximately arched, and by extending the portion near the vertex 22', which is the connecting portion with the overhanging portion 22, upward, the nose frame portion is shaped like an arch. Compared to the case where the nose frame section 25 extends straight toward the nose of the wearer S without being curved upward, the portion of the nose frame section 25 that is close to the connection section with the overhang section 22 makes it easier to visually recognize food and drink. It is possible to prevent it from becoming difficult to eat or drink due to the obstruction of the water.

In addition, as shown in FIGS. 1 and 2, the end of the nose frame portion 25 is formed into a bifurcated portion 26, so that it fits closely to the nose of the wearer S and allows the nose frame portion 25 to be removed from the nose. It is designed to prevent slippage.

Note that the distance between the projecting portion 22, the apex portion 22', and the nose of the wearer S may vary depending on the physique of the wearer S, so in order to accommodate these differences in physique, for example, The nose frame part 25 is composed of a first part on the vertex 22' side and a second part on the bifurcated part 26 side, and the second part is slidably attached to the first part in stages. The wearer S may be able to adjust the length of the frame portion 25 according to his/her physique.

The mounting frame 2 including these nose frame portions 25 is molded by injection molding of heat-resistant polypropylene resin, and has antifouling properties, heat resistance, and mass productivity. Although the mounting frame 2 can be washed, dried and reused repeatedly in the same way as tableware in a dishwasher owned by a store, the present invention is not limited to this, and heat-resistant polypropylene is used. Resins other than resins, such as thermoplastic chlorofluorocarbon resins such as tetrafluoroethylene resins, thermosetting resins such as unsaturated polyesters, etc. may be used.

In addition, these mounting frames 2 may be colored in different colors (for example, 7 colors), and by remembering the color of the face shield 1 used for eating and drinking at a dinner etc., multiple people can use it at the same time. It may be possible to easily determine which face shield 1 for eating and drinking is the one used by the user when the user leaves his/her seat.

Next, the first shield film 3 and the second shield film 4 of this embodiment, which are attached to the mounting frame 2, will be explained. The first shield film 3 and the second shield film 4 of this embodiment are both made of a highly transparent polypropylene resin film with a thickness of about 0.2 mm, and have high transparency, making it suitable for use as a face shield for eating and drinking. 1, the food and drink containers can be visually recognized through the first shield film 3 and the second shield film 4, making it easier to grasp the position of the food and drink containers and eat and drink. It is now possible to do so.

Note that the second shield film 4 has a high height so that the relative position of the food or drink container and the first shield film 3 in the space formed between the first shield film 3 and the face can be grasped. Although it is preferable that the first shield film 3 is transparent, for example, by using a film with lower transparency than the second shield film 4, the position of the first shield film 3 can be determined. It may have appropriate transparency or translucency so that it is easy to see through the second shield film 4 and also allow the position of food and drink placed beyond the first shield film 3 to be seen.

As shown in FIG. 2(b), the first shield film 3 is a substantially rectangular strip-shaped film having two small rounded corners and two large rounded corners, A mounting hole 31 is formed near the two small rounded corners for fitting the first shield film 3 into the first mounting protrusion 23 of the mounting frame 2 and rotatably mounting it. .

In addition, a stopper portion 32 that protrudes from the surface of the first shield film 3 when bent is formed at a predetermined position near the side (upper end side) connecting the two small rounded corners. As will be described later, the stopper part 32 comes into contact with the upper surface of the overhang part 22 of the mounting frame 2, so that it is possible to prevent the first shield film 3 from slipping down below a predetermined position. It has become.

Further, as shown in FIG. 2(b), the second shield film 4 is fan-shaped in a size corresponding to the overhang 22 of the mounting frame 2, so that the overhang 22 and the wearer S can be connected to each other. It is now possible to close off almost the entire space formed between the face and the face. In this way, making the second shield film 4 have a size and shape that can be closed prevents droplets from scattering from the space formed between these projecting parts 22 and the face of the wearer S. Although it is preferable to improve the effect, the present invention is not limited to this, and the size and shape of the second shield film 4 are such that there is at least a gap between the projecting portion 22 and the face of the wearer S. It is sufficient if it is possible to cover at least a portion of the space to be formed.

Furthermore, as shown in FIG. 2(b), a broken portion 42 is formed in the center of the second shield film 4 so as to connect to a fan-shaped arcuate side, which is a specific side of the present invention. By forming the portion 42, the second shield film 4 can be easily deformed even if food or drink containers come into contact with the second shield film 4. This can prevent damage or falling off from the mounting frame 2 due to contact. Note that these broken portions 42 are not essential; for example, if the second shield film 4 is sufficiently thin and can be easily deformed by contact with food or food containers, these broken portions may be formed. 42 may be omitted.

Further, in this embodiment, the second shield film 4 is provided with only one broken portion 42, but the present invention is not limited to this, and the shape, number, etc. of these broken portions 42 may vary. It may be determined as appropriate depending on the thickness and characteristics of the film used.

In addition, since the first shield film 3 and the second shield film 4 are made of polypropylene resin, which is a difficult-to-adhesive resin, food and drink may not come into direct contact with the first shield film 3 or the second shield film 4. However, the present invention is not limited to this, and the present invention is not limited to these polypropylene resin films. Other resin films may also be used.

Specifically, it may be a polyethylene terephthalate (PET) film that has been surface treated to prevent adhesion, or in this embodiment, the first shield film 3 and the second shield film 4 are disposable films that are replaced each time they are used. Since it is a film, for example, a transparent film made of biodegradable resin may be used.

Further, in this embodiment, the first shield film 3 and the second shield film 4 have the same thickness, but the present invention is not limited to this, and the first shield film 3 is As will be described later, when the film comes into contact with food containers such as beer mugs, it rotates and moves upward, so the film is designed to prevent bending due to contact with these food containers. The thickness of the first shield film 3 may be made thicker than the thickness of the second shield film 4.

Next, the flow of assembling the face shield 1 for eating and drinking according to this embodiment will be explained using FIG. 3. First, as shown in FIG. The arc-shaped portion of the mounting frame 2 is arranged so that it corresponds to the overhanging part 22 of the mounting frame 2, and the four mounting holes 41 are sequentially fitted into the four second mounting protrusions 24, and the lower surface side of the mounting frame 2 is inserted. Attach to.

As shown in the enlarged view of FIG. 3(a), the second mounting protrusion 24 has a diameter at the lower end that is slightly larger than the diameter of the mounting hole 41, and a diameter at an intermediate position in the vertical direction that is larger than the diameter of the mounting hole 41. The diameter is slightly smaller than that of 41, so that it has a cylindrical shape with a step formed therein, and the lower end of the second mounting protrusion 24 is formed by deforming the mounting hole 41 of the second shield film 4. By pushing the mounting hole 41 into the small diameter portion, the mounting hole 41 is retained by being locked to the stepped portion. The second shield film 4 is immovably attached to the mounting frame 2 by pushing the mounting holes 41 into the four second mounting protrusions 24 .

Next, after preparing to attach the first shield film 3 by bending the two stopper parts 32 of the first shield film 3 toward the inner surface side that is the mounting frame 2 side, as shown in FIG. 3(b), The first shield film 3 is attached to the mounting frame 2 by pushing the two mounting holes 31 of the first shield film 3 into the first mounting projections 23 of the mounting frame 2.

Although the details of the first mounting protrusion 23 are not shown, the diameter of the outer tip of the first mounting protrusion 23 is slightly larger than the diameter of the mounting hole 31, similar to the second mounting protrusion 24. The diameter at the intermediate position in the horizontal direction is made slightly smaller than the diameter of the mounting hole 31, thereby forming a cylindrical shape with a stepped portion. By deforming the mounting hole 31 of the shield film 3 and pushing it into the small diameter portion, the mounting hole 31 is retained by being locked to the stepped portion. In this way, the first shield film 3 is held by the mounting hole 31 being pushed into the two first mounting protrusions 23 formed to protrude toward the outer circumference of the mounting frame 2. The stopper portion 32 is rotatably attached to the mounting frame 2 about the two first attachment protrusions 23 as fulcrums, and as shown in the enlarged view of FIG. 3(b), the stopper portion 32 is bent in advance. By coming into contact with the upper surface of the mounting frame 2, the first shield film 3 is held at a predetermined position where the upper side of the first shield film 3 and the upper surface of the mounting frame 2 are substantially parallel.

When the wearer S wears the face shield 1 for eating and drinking assembled in this way, as shown in the enlarged view of FIG. By adjusting and wearing the annular rubber stopper 27 made of silicone rubber, which is a member, by changing the placement position according to the person's physique, the eating/drinking face shield 1 is displaced (shifted) in front of the face. When the nose frame part 25 separates from the nose of the wearer S, the mounting frame 2 is no longer supported by the nose frame part 25, and the gap between the first shield film 3 and the mouth of the wearer S is reduced. This can prevent the space from becoming narrow.

In this embodiment, the rubber stoppers 27 are made of silicone rubber, which is a heat-resistant rubber, so that these rubber stoppers 27 can be washed and dried in a dishwasher or the like together with the mounting frame 2, and then reused. The present invention is not limited to this, and elastic members other than silicone rubber may be used and made disposable.

When wearing the face shield 1 for eating and drinking assembled as described above, as shown in FIG. The film 4 suppresses the scattering of droplets.

When the wearer S eats or drinks, as shown in FIG. 4(b), since the mounting frame 2 is supported by the nose frame section 25, the first shield film 3 and the mouth section of the wearer S are connected. Since a wide space is formed between them, food can be carried to the mouth through the space and eaten without moving the first shield film 3 overhead.

In addition, when eating or drinking in a relatively large food container such as a beer mug, as shown in FIG. By lifting a food container such as a beer mug and carrying it to the mouth, the beer mug, which is a food container, comes into contact with the first shield film 3, so that the first shield film 3 automatically moves in the overhead direction. Therefore, the first shield film 3 does not get in the way, and you can easily eat and drink using the beer mug, which is a food and drink container. When the beer mug, which is the food and drink container, is moved downward, the first shield film 3 automatically rotates and moves downward, so that the stopper part 32 closes to the mounting frame. By returning to the state shown in FIG. 4(a) in which the first shield film 3 is in contact with the upper surface of the overhanging portion 22 of 2, the wearer S does not need to raise and lower the first shield film 3 one by one, thereby preventing droplets from scattering while eating or drinking. can be more reliably prevented.

As described above, according to the face shield 1 for eating and drinking of the present embodiment, by having the nose frame part 25 that can support the protruding part 22, there is a gap between the first shield film 3 and the mouth of the wearer S. Since it becomes possible to widen the space formed, it becomes possible to eat and drink with the first shield film 3 attached, so that the scattering of droplets during eating and drinking can be effectively prevented.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and any changes or additions that do not depart from the gist of the present invention are included in the present invention. It will be done.

For example, in the above embodiment, the nose frame portion 25 is formed into a single piece, but the present invention is not limited to this, and the nose frame portion may be formed from a plurality of pieces. However, by having a shape in which the part near the apex 22' branches into two parts in the middle of the nose frame part, the nose frame part does not obstruct the visibility of food and drink containers. You can also do this.

Further, in the above embodiment, the second shield film 4 is provided, but the present invention is not limited to this. For example, depending on the shape of the projecting portion 22, etc. The shield film 4 may not be provided.

Furthermore, in the above embodiment, by being able to be worn on the ears of the wearer S, the size of the first shield film 3 can be made small and lightweight, and the first shield film 3 can be easily rotated automatically. At the same time, it is preferable that the face shield 1 for eating and drinking can be easily attached and detached, which improves the attachability of the face shield 1. However, the present invention is not limited to this. In this case, the size of the first shield film 3 may be set to cover the entire face.

Further, in the above embodiment, the rubber stopper 27 is provided, but the present invention is not limited to this, and depending on the shape of the mounting part, the rubber stopper 27 may not be provided. good.

Further, in the above embodiment, in order to reduce costs by simplifying the structure, the first shield film 3 is movable in the vertical direction by rotation, but the present invention is not limited to this. For example, the first shield film 3 may be slidable in the vertical direction by providing a sliding mechanism.

Further, in the above embodiment, the first shield film 3 and the second shield film 4 are made into separate films, but the present invention is not limited to this, and for example, as shown in FIG. Like the shield film 100 shown in the modified example, the first shield film 3 and the second shield film 4 may be integrated and punched to reduce costs. Note that in FIG. 5, parts common to those in the above embodiment are designated by the same reference numerals, and a description thereof will be omitted.

Specifically, as shown in FIG. 5, the apex part of the second shield film 4' and the center part of the upper side of the first shield film 3' are connected at the bent part M, and the second shield film 4' Approximately T-shaped engagement protrusions 45 are formed near the two corners of the first shield film 3', and insertion holes 33 through which the engagement protrusions 45 can be inserted are provided at corresponding positions of the first shield film 3'. to drill.

Further, the second shield film 4' is provided with a long hole 43 through which the nose frame portion 25 can be inserted, and a broken portion 44 to facilitate insertion of the bifurcated portion 26.

Further, like the stopper part 32, the first shield film 3' is provided with an upper position stopper part 34 for holding the shield film 100 in the upper position when it moves upward.

Then, by bending the bent portion M and inserting and engaging the engaging protrusion 45 into the insertion hole 33, the box-shaped shielding film 100 with a semicircular cross-sectional view and an open bottom is created. shall be.

Then, by inserting the nose frame part 25 into the elongated hole 43 of the second shield film 4' and covering the mounting frame 2 with the box-shaped shield film 100, a face for eating and drinking similar to that of the above embodiment is formed. A shield can be formed, and the shield film 100 can also be provided with a function of being able to be held in an upper position as needed.

It goes without saying that the upper position stopper part 34 in the above modification may be applied to the first shield film 3 of the face shield 1 for eating and drinking in the embodiment.

Further, the shape, number, etc. of the stopper part 32 and the upper position stopper part 34 are not limited to the above-described embodiments and modified examples, and the function of holding the first shield film 3 and the shield film 100 in a predetermined position is They can be of any shape or number as long as they are of any type.
