Description

[Technical Field]

[0001] The present invention relates to a cover member. [Background technology]

[0002] Conventionally, there are eye care technologies that attach a device to eyewear that sprays mist toward the eyes. For example, a technology that attaches a device that ejects minute droplets to eyewear (see, for example, Patent Document 1), a technology that attaches a device that atomizes and sprays eye drops to eyewear (see, for example, Patent Document 2), and a health device that shoots a mist jet toward the eyes (see, for example, Patent Document 3) are known.

[0004] However, in the prior art, no particular consideration has been given to the lid of the liquid storage portion that stores the liquid. Here, the inventor conducted an experiment in which the lid of the liquid storage portion was formed using a soft material with elasticity, such as silicone, and a liquid refill port was provided on the lid to refill the liquid. In this experiment, the inventor discovered a new problem in that, depending on the shape and material of the lid, the lid may deform and come off when refilling the liquid.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to enable stable replenishment of liquid through a lid member of a liquid storage portion. [Means for solving the problem]

[0006] In one aspect of the present invention, the lid member comprises a lid portion that covers the opening of a liquid storage portion in a spray mechanism provided in eyewear, a supply port provided on the plane of the lid portion that allows liquid to be supplied to the liquid storage portion, and an extension portion that extends from the plane of the lid portion toward the liquid storage portion and follows the inner wall of the liquid storage portion. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a lid member for a liquid storage portion that enables stable replenishment of liquid via the lid member for the liquid storage portion. [Brief explanation of the drawings]

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the embodiments described below are merely examples, and are not intended to exclude various modifications or technical applications not explicitly stated below. In other words, the present invention can be implemented with various modifications within the scope of its spirit. Furthermore, in the following description of the drawings, identical or similar parts are denoted by identical or similar reference numerals. The drawings are schematic and do not necessarily correspond to actual dimensions, ratios, etc. Parts in the drawings may have different dimensional relationships or ratios.

[0010] [Embodiment] <Eyewear> FIG. 1 is a perspective view showing an example of eyeglasses 100 according to an embodiment, viewed from the front. As shown in FIG. 1, eyeglasses 100 are an example of eyewear, and include a pair of lenses 110 and a frame 120. Note that, although the lenses 110 are described as a pair in this embodiment, they do not necessarily have to be a pair. Also, although the lenses 110 are described as a component of eyeglasses 100 in this embodiment, the lenses 110 themselves are not necessarily a component required for eyeglasses 100.

[0011] The frame 120 includes, for example, a front 140, a pair of temples 180 rotatably connected to both the left and right ends of the front 140, and a pair of end pieces 160 attached to the rear sides of the pair of temples 180. The frame 120 also holds a pair of lenses 110 and holds the lenses 110 and the front 140 in an appropriate position relative to the user's eyes and head.

[0012] The front end 140 supports the pair of lenses 110. The temples 180, together with the end pieces 160, press against the temporal regions of the user's head, holding these regions in place. The end pieces 160 also come into contact with the upper and rear portions of the user's ears, preventing the eyeglasses 100 from falling off. Note that the end pieces 160 are not necessarily a necessary component of the eyeglasses 100.

[0013] In the following description, for convenience, the longitudinal direction of the front 140 shown in FIG. 1 will be referred to as the "left-right direction." Furthermore, when the eyeglasses 100 are worn, the left side as seen from the user will be referred to as the "left side" (X2), and the right side as seen from the user will be referred to as the "right side" (X1). Furthermore, the short direction of the front 140 will be referred to as the "up-down direction," the direction above the head will be referred to as the "upward direction" (Z1), and the direction below the head will be referred to as the "downward direction" (Z2). Furthermore, the thickness direction of the front 140 will be referred to as the "front-rear direction," the front 140 side will be referred to as the "forward direction" (Y1), and the end piece 160 side will be referred to as the "rearward direction" (Y2).

[0014] The eyeglasses 100 to which this embodiment is applied are formed symmetrically about the glabella (bridge) 142. Therefore, in the following description, the symmetrical configuration will not be distinguished between left and right, and only the configuration on one side of the drawing will be described with reference numerals.

[0015] The front 140 has, for example, a plate-like configuration extending in the left-right direction and curved to protrude forward to fit the user's face. The front 140 also has a central glabella 142, a pair of nose pads 144 attached to the left and right sides of the back surface of the glabella 142, a pair of rims 146 formed on both the left and right ends of the glabella 142, a pair of end pieces 147 formed on each end of the pair of rims 146, and a pair of first hinge portions (not shown) attached to the back surfaces of the pair of end pieces 147.

[0016] The glabellar portion 142 connects the left and right portions of the front 140 (glasses 100). The glabellar portion 142 is, for example, a curved plate-like member, and may be made of resin or the like.

[0017] The nose pads 144 support the front 140 by pinching the sides of the user's nose, and maintain the height of the front 140 relative to the user's eyes. The nose pads 144 are, for example, a cling type having a resin pad portion and a metal support portion. By deforming the pad portion and the support portion, it is possible to fine-tune the posture of the front 140 relative to the user's nose and eyes (for example, the distance between the corneal vertices).

[0018] The rim 146 holds the lens 110. The rim 146 is, for example, a ring-shaped member formed to fit the shape of the lens 110, and is made of resin or the like.

[0019] A first hinge portion (not shown) is formed on the end piece 147. The end piece 147 is, for example, a curved plate-like member, and is made of resin or the like.

[0020] The first hinge portion functions as an example of a connecting portion, and by combining with a second hinge portion (not shown) having a plate-like shape formed on the temple 180 side, it connects the temple 180 rotatably to the front 140. In other words, the first hinge portion and the second hinge portion form a hinge.

[0021] The temples 180 are L-shaped members that are curved to fit the temporal region of the head. The temples 180 are connected to the front 140 in a rotatable manner within a range from a folded position where the angle between the temples 180 and the front 140 is smallest to an open position where the angle between the temples 180 and the front 140 is largest.

[0022] A spray mechanism is provided for the end piece 147 or the temple 180. In the embodiment, a cartridge 200 that is detachable from the end piece 147 or the temple 180 will be described as an example of the spray mechanism. An example in which the cartridge 200 is attached along the longitudinal direction of the temple 180 is shown, but this example is not limiting. The cartridge 200 also has a liquid storage section that stores a mist liquid, a spray element that sprays the mist using the liquid, and a control circuit board that controls the spray element. The cartridge 200 may also be configured without a spray element or control circuit board, in which the liquid in the liquid storage section evaporates into gas, and the gas is released to the outside.

[0023] <Cartridge> An example of the cartridge 200 will be described with reference to FIGS. 2 to 4. FIG. 2 is an exploded perspective view (part 1) showing an example of the cartridge 200 according to the embodiment. The example shown in FIG. 2 shows an exploded perspective view from above of an area where components for spraying mist are stored. The cartridge 200 has a main body storage section 220, a spray component cover section (or main body lid section) 210, and a lid member 222. The cartridge 200 may be made of, for example, resin. The lid member 222 may also be made of a soft material such as elastic silicone or rubber. The cartridge 200 shown in FIGS. 2 to 4 shows an example attached to the right (X1) temple 180, for example, and is a type that sprays toward the eye.

[0024] In the example shown in FIG. 2 , a lid member 222 is fitted into the opening of the liquid storage portion 230 in the main body storage portion 220, and a spray component cover portion 210 is attached to cover the spray element 300 and the control circuit board 400 on the spray component side. When the lid member 222 and the spray component cover portion 210 are attached to the main body storage portion 220, they may be collectively referred to as the main body storage portion. The cartridge 200 is provided in the eyewear, but may be literally attached and connected, or may be provided as a spray mechanism that is integrally formed with a part of the eyewear, such as the temple 180 or the end piece 147, and cannot be removed. As an example, the main body storage portion 220 has a connection mechanism that can be detachably connected to the temple 180 or the end piece 147 of the eyewear, as described below. By providing the cartridge 200 detachable from the temple 180 or the end piece 147 of the eyewear, the frame 120 does not get in the way when refilling the liquid, making the refilling process easier.

[0025] The spray component cover portion 210 has one opening 202 at a position corresponding to the arrangement position of the spray element 300. Through this opening 202, the mist sprayed by the spray element 300 is released to the outside. The lid member 222 has two openings 204, one of which functions as a liquid supply port (e.g., an inlet) and the other functions as an air vent for adjusting the pressure inside the liquid storage portion 230. Note that the lid member 222 may have only one opening, which may function as both the supply port and the air vent. The lid member 222 is also provided with an extension portion 2221. The extension portion 2221 will be described in detail later.

[0026] The cartridge 200 has a width direction, a height direction, and a depth direction, and has a polyhedral shape (e.g., a hexahedral shape). For example, the cartridge 200 has a shape similar to a rectangular parallelepiped. The cartridge 200 also includes a main body housing 220 whose width direction is its longitudinal direction. For example, when the temples 180 are unfolded (worn), the width direction of the cartridge 200 is aligned with the longitudinal direction of the temples 180, the depth direction is aligned with the left-right direction of the front 140, and the height direction is aligned with the vertical direction of the face. The shape of the main body housing 220 shown in FIG. 2 is merely an example, and does not have to be aligned with a rectangular parallelepiped shape. The planar shape in the width and height directions may be a trapezoid, for example. The shape may be determined appropriately depending on the position where the cartridge 200 is attached to the eyewear 100 main body.

[0027] Furthermore, spray component cover portion 210 has a wall 212 that forms opening 260 (see FIG. 3) of main body housing portion 220 when attached. For example, wall 212 may be U-shaped so as to protrude from the spray component cover portion 210 side. Opening 260 may have a protruding connection mechanism from main body housing portion 220 to temple 180 or end piece 147 protruding therefrom, or may have a recess formed therein that receives a protruding connection mechanism provided on temple 180 or end piece 147.

[0028] Moreover, spray component cover part 210 has protrusions 214 (see FIG. 4) at each of its four corners, which are press-fit into corresponding recesses 224 (see FIG. 2) of main body accommodating part 220, thereby fixing spray component cover part 210 to main body accommodating part 220 (see FIG. 3). Protrusions 214 include, for example, bosses. Protrusions 214 may have different lengths or shapes, and protrusions 214 and recesses 224 on the side of accommodating area 250 that accommodates control circuit board 400 may be replaced with a screw-fastening structure.

[0029] 3 is an external perspective view showing an example of cartridge 200 according to an embodiment. Cartridge 200 is formed with opening 202 that allows mist to pass to the outside, opening 204 that serves as a liquid supply port and ventilation port for liquid storage section 230, and opening 260 that forms a connection mechanism with temple 180 and end piece 147. A connection terminal (e.g., a USB connector) that can also be used for power supply may protrude from opening 260.

[0030] FIG. 4 is an exploded perspective view (part 2) showing an example of the cartridge 200 according to the embodiment. Unlike FIG. 2, the example shown in FIG. 4 shows an exploded perspective view from above on the liquid storage portion 230 side. In the example shown in FIG. 4, protrusions 214 are formed at the corners on the back side of the spray component cover portion 210. One or more ribs 216 may be provided so as to extend inward from the wall 212 that forms the opening 260. For example, the ribs 216 may press down on the connection terminals protruding from the opening 260, thereby stably positioning the connection terminals.

[0031] <Spray element> The spray element 300 is an element that sprays the liquid contained in the liquid container 230 as a mist. The mist is, for example, a moisture mist, and contains at least minute liquid particles. The spray element 300 is either an ultrasonic oscillation element that can vibrate the liquid to generate at least minute liquid particles, or an atomizing element that can generate a reduced pressure state using an airflow to turn the liquid into a mist of minute liquid particles.

[0032] The structure and shape of the spray element 300 are not particularly limited, but a thin, flat shape is preferable. The size and shape of the spray element 300 are preferably determined according to the location where it is to be attached. The spray element 300 is housed in a housing area 240 arranged in parallel with the liquid storage section 230.

[0033] <Liquid storage section> The liquid storage section 230 is a section that stores the liquid to be atomized by the spray element 300. The structure and shape of the liquid storage section 230 are not particularly limited as long as it is configured to have the function of supplying the liquid to the spray element 300. In the example shown in FIGS. 2 to 4, the liquid storage section 230 is provided inside the cartridge 200.

[0034] Liquid storage section 230 may contain the liquid as is, or may contain a liquid-absorbing or liquid-retaining material such as a sponge or felt that has been soaked in the liquid. In addition, the bottom of liquid storage section 230 may be configured to have a supply port that supplies liquid to spray element 300.

[0035] <Cover parts> 5 to 9, an example of the lid member 222 will be described. The lid member 222 includes a lid portion (flat portion of the upper surface) 2220 that covers the opening of the liquid storage portion 230 provided in the cartridge 200 that can be attached to the eyewear 100, a refill port (or opening) 204 provided on the flat surface of the lid portion 2220 that allows liquid to be refilled into the liquid storage portion 230, and an extension portion 2221 that extends from the flat surface (e.g., the back surface) of the lid portion 2220 toward the liquid storage portion 230 and follows the inner wall of the liquid storage portion 230. For example, the lid portion 2220 is a substantially flat surface with a predetermined thickness, and its shape is not particularly limited as it is determined by the opening of the liquid storage portion 230. The cartridge 200 may be provided integrally with the eyewear 100.

[0036] FIG. 5 is a top view showing an example of the cartridge 200 and the lid member 222 according to the embodiment. In the example shown in FIG. 5, a cross-shaped notch is formed as the supply port 204 on the top surface of the lid portion 2220 of the lid member 222. For example, the injection port of a bottle containing liquid is inserted into the cross portion of the cross-shaped notch, and the liquid is injected. At this time, it is necessary to prevent the lid portion 2220 from being deformed and collapsed or the lid member 222 from being removed by inserting the injection port of the bottle into the supply port 204. Therefore, the lid member 222 according to the embodiment is provided with, for example, an extension portion 2221 that extends in a substantially vertical direction from the plane (e.g., the back surface) of the lid portion 2220 and follows the inner wall of the liquid storage portion 230.

[0037] FIG. 6 is a perspective view showing an example of the cartridge 200 when the lid member 222 according to the embodiment is fitted into the liquid storage portion 230. As shown in FIG. 6, the extension 2221 of the lid member 222 is formed to fit along the inner wall of the liquid storage portion 230. As a result, frictional force is generated when the extension 2221 comes into contact with the inner wall of the liquid storage portion 230. As a result, the force acting on the peripheral edge of the lid portion 2220 due to deformation of the lid portion 2220 is dispersed to the extension 2221, allowing the force associated with this deformation to be offset by the frictional force with the inner wall and the resistance (repulsion force). This prevents the lid portion 2220 from deforming, collapsing, or coming off, enabling stable liquid replenishment. Furthermore, the above-described configuration eliminates the need to increase the number of parts of the lid member 222. Furthermore, the lid member 222 can be formed in a simple configuration and can be molded as a single unit.

[0038] The extension portion 2221 may also be formed by a wall that extends along the circumferential direction of the inner wall of the liquid storage portion 230. The extension portion 2221 may also be formed in a cylindrical shape, as shown in Fig. 6. This makes the frictional force between the extension portion 2221 and the inner wall of the liquid storage portion 230 uniform, maximizing the frictional force and enabling more stable liquid replenishment.

[0039] 6, the thickness of lid portion 2220 in a predetermined region including opening 204 of lid portion 2220 may be thinner than the thickness of lid portion 2220 in other regions. For example, if the thickness of lid portion 2220 in other regions is 2 mm, the thickness of lid portion 2220 in the predetermined region may be 1 mm. This reduces the resistance when inserting the injection port of the bottle into opening 204, and reduces the force applied to lid portion 2220.

[0040] 7 is a side view showing an example of an exploded view of the liquid storage portion 230 and the extension portion 2221 according to the embodiment. In the example shown in FIG. 7, the positional relationship between the liquid storage portion 230 inside the cartridge 200 and the supply port 232 to the spray element 300 is indicated by a dotted line. In addition, in the example shown in FIG. 7, it is preferable to provide a slope on the bottom of the liquid storage portion 230 so that the supply port 232 to the spray element 300 is at the deepest part. The liquid storage portion 230 is provided with the supply port 232 that supplies liquid to the spray element 300, and the bottom surface of the liquid storage portion 230 is provided with a slope so that the liquid flows toward the supply port 232.

[0041] Furthermore, as the bottom surface of the liquid storage portion 230 is inclined, the ends of the extension direction of the extension portion 2221 are also inclined along the inclination of the liquid storage portion 230. For example, the length of the extension direction of the extension portion 2221 gradually increases from one end to the other end in the longitudinal direction of the lid portion 2220. Furthermore, since the length in the extension direction is determined by the inclination of the bottom surface of the liquid storage portion 230, the position where the length of the extension direction of the extension portion 2221 is longest is the position of the deepest part of the liquid storage portion 230, and this position of the deepest part may be any position in the longitudinal direction of the lid portion 2220.

[0042] FIG. 8 is a perspective view showing an example of an exploded view of the liquid storage portion 230 and the extension portion 2221 according to the embodiment. For ease of explanation, FIG. 8 omits the spray element 300 and other components that are not part of the liquid storage portion 230 and the extension portion 2221. In the example shown in FIG. 8 , the wall forming the extension portion 2221 may have an opening 2222 that allows liquid in the liquid storage portion 230 to pass to the outside. For example, the opening 2222 may be located at a position corresponding to the opening 202 of the cartridge 200, and the size of the opening 2222 of the extension portion 2221 may be determined according to the size of the opening 202 of the cartridge 200. As a result, the liquid stored inside the wall passes through the opening 2222 and is ultimately released into space as gas through the opening 202 of the cartridge 200. The amount of liquid that flows out can be adjusted by the size or position of the opening 2222 of the extension portion 2221.

[0043] Furthermore, the wall of the extension portion 2221 may have a window portion that allows the amount of liquid in the liquid storage portion 230 to be confirmed. For example, the window portion may be a slit or a rectangular opening extending from the tip of the extension portion 2221, and its shape is not particularly important as long as it allows the amount of liquid in the liquid storage portion 230 to be confirmed. In this case, at least the portion of the cartridge 200 that corresponds to the window portion is formed from a transparent material so that the window portion can be viewed from the outside. This allows the user to check the amount of liquid in the liquid storage portion 230 from the outside and know when to refill the liquid. Note that the window portion may be unnecessary if the lid portion 222 is formed from a transparent soft material. In this case, a transparent member, slit, opening, or the like is provided in the cartridge 200 in the portion that corresponds to the window portion, allowing a portion of the interior of the liquid storage portion 230 to be viewed from the outside.

[0044] 6 to 8, the extension portion 2221 may extend to the bottom of the liquid storage portion 230. In this way, the bottom surface of the extension portion 2221 comes into contact with the bottom surface of the liquid storage portion 230, and the pushing force from the top surface of the lid portion 2220 when inserting the inlet of the bottle can be offset by the repulsive force from the bottom surface of the liquid storage portion 230, allowing for more stable liquid replenishment. In addition, the bottom surface of the extension portion 2221 comes into contact with the bottom surface of the liquid storage portion 230, and this prevents the lid member 222 from sinking into the liquid storage portion 230. In addition, if the bottom surface of the liquid storage portion 230 is inclined (see FIG. 7, for example), the end of the extension direction of the extension portion 2221 may be formed along this inclination. In this way, even if the bottom surface of the liquid storage portion 230 is inclined, the length of the extension portion 2221 in the extension direction extends to the bottom surface along the inclination, and the lid member 222 can also receive a repulsive force from the inclined surface.

[0045] The thickness of the lid portion 2220 shown in FIG. 8 is defined as W1. FIG. 9 is a diagram showing an example of the lid member 222 according to the embodiment as viewed from the back. The thickness of the extension portion 2221 shown in FIG. 9 is defined as W2. In this case, the thickness W2 of the extension portion 2221 may be thinner than the thickness W1 of the lid portion 2220. This makes it possible to ensure a larger amount of liquid to be stored in the liquid storage portion 230 (in the extension portion 2221). Note that the thickness W2 of the extension portion 2221 does not need to be uniform; it is sufficient that the thickness W2 of at least a predetermined region is thinner than the thickness W1 of the lid portion 2220.

[0046] 2 to 4 and the openings shown in FIGS. 5 to 9. For example, the size and shape can be changed as appropriate. The shape of the extension 2221 is not limited to the cylindrical shape shown in FIG. 9, etc. For example, it may be a columnar shape arranged at the corner of the liquid storage section 230, or a lattice shape. The length of the extension 2221 in the extension direction does not have to extend to the bottom of the liquid storage section 230, as long as there is sufficient friction and resistance (repulsion) with the inner wall.

[0047] Although the present invention has been described above using various embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. It is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention. [Explanation of symbols]
