[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-083501

[0005] This lighting fixture has a light source installed inside the opening of the transparent plastic bottle, or inserted through the opening and attached to the inside of the plastic bottle. This lighting fixture uses the plastic bottle as an empty container, and is configured to be watertight for drinking water, etc. However, there is no known lighting fixture that has a light source outside the plastic bottle and irradiates light from the outside of the plastic bottle. Summary of the Invention [Problem to be solved by the invention]

[0006] The problem that this invention aims to solve is to provide a simple lighting device that takes advantage of the transparent plastic bottle body when the plastic bottle is carried, and the properties of the liquid when a beverage (liquid) is sealed in the bottle, such as fluidity and light transmittance, while maintaining the convenience of attachment and detachment to the plastic bottle and to personal belongings, and further alerts car drivers and motorbike drivers traveling at night to the presence of pedestrians, thereby improving pedestrian safety from the perspective of traffic safety.

[0007] When walking at night, it is dark, so without lights, pedestrians could be at risk of being hit by cars or bicycles that are out of sight, or they could trip over steps or obstacles in the road, so having lights reduces the crime rate.

[0008] The present invention has been made in view of the above-mentioned problems, and its object is to provide a lighting fixture for plastic bottles that contributes to traffic safety for pedestrians at night. [Means for solving the problem]

[0009] The lighting fixture for plastic bottles of the present invention is a lighting fixture that can be attached to a transparent plastic bottle that is carried on the body, and comprises a snap-fit ​​male member (11) having a fitting portion (17) that can be fitted to the neck portion (3) of a plastic bottle (2) at one end and a snap-fit ​​male portion (12) at the other end; a personal item fastening member (31) having a fastening portion (32) that can be fastened to a personal item; a snap-fit ​​female member (41) having a female portion (42) that can be fitted to the male portion at one end and a snap-fit ​​female member (41) whose other end is connected to the other end of the personal item fastening member; The light source is housed in a light source protection portion (25) formed in the The plastic bottle Transparent shoulder (4) and body (5) a light source (21) for illuminating the exterior wall; A changeover switch (22) for switching the light source on and off; Equipped with El . The front surface (251) of the light source protection unit faces the transparent shoulder of the plastic bottle without contacting it and is made of a resin that transmits light, and the changeover switch is arranged to protrude downward from a hole formed in the underside of the light source protection unit.

[0010] The lighting device for plastic bottles of the present invention is small and highly portable, and can function as a lighting device in dark places such as at night.

[0011] When the plastic bottle is not carried or when it is used separately from the plastic bottle, the lighting fixture for the plastic bottle of the present invention can be easily used and stored as a stand-alone item in a shoulder bag, handbag, or carrier bag.

[0012] Furthermore, with the lighting device for plastic bottles of the present invention, when carrying a plastic bottle, by engaging the engaging portion of the personal engaging member with the engaging portion of a personal garment, the light source can be turned on when walking at night, increasing the degree of safety and security while leaving both hands free to use.

[0013] When walking at night with a light source on, shining light from the outside on the outer wall of the transparent plastic bottle causes diffuse reflection, making it visible from all angles and in all directions as if it were a light source much larger than the light source itself. When there is a beverage inside the plastic bottle, the light is also diffused by the liquid, making the inside of the bottle glow brightly. This allows you to walk safely and securely at night. In the case of plastic bottles, the surface is not made into a perfect mirror finish during molding, but rather has an uneven surface, so the irradiated light has a large diffusion effect regardless of the shape of the plastic bottle.

[0014] The female part of the snap-fit ​​male member can be easily separated from the male part by pushing it in manually, and the plastic bottle can be easily removed from the body to make it easier to drink.

[0015] The lighting fixture of the present invention does not impair the function of storing beverages in the plastic bottle, so that when in use, the wearer can drink the beverages in the plastic bottle as needed.

[0016] Furthermore, with the lighting fixture for plastic bottles of the present invention, the plastic bottle can be easily separated from the snap-fit ​​female member by separating the female part from the male part of the snap-fit ​​male member, so the snap-fit ​​female member side of this fixture can be used alone as a directional light source.

[0017] The fastening member for personal items can be easily detached from personal items such as belts, bags, etc. When the fastening member for personal items is detached from the body, it can also be used as a hanging portable lighting fixture similar to a lantern.

[0019] Hereinafter, a lighting fixture for a plastic bottle according to an embodiment of the present invention will be described with reference to the drawings. Note that, in a plurality of embodiments, substantially the same components are designated by the same reference numerals, and description thereof will be omitted.

[0020] (First embodiment) A first embodiment of the present invention will be described with reference to FIGS.

[0021] As shown in Figures 1 and 2, the lighting fixture for plastic bottles comprises a snap-fit ​​male member 11, a personal item fastening member 31, a snap-fit ​​female member 41, and an LED lamp 21 as a light source.

[0022] The snap-fit ​​male component 11 is made of resin and has a basic U-shape. The mating portion 17 of the snap-fit ​​male component 11 has a circular hole 16 and a slit 18. The hole 16 of the mating portion 17 can fit into the neck portion 3 of a transparent plastic bottle 2. The mating portion 17 of the snap-fit ​​male component 11 has a bent, extending inclined portion 19. The inclined portion 19 has a slit 18 in the center. The pair of claws 13, 14 extending from the inclined portion 19 are flexible enough to use the space of the slit 18 as a bending margin so as to bend in directions 131, 141 shown in Figure 5. By bending in a direction narrowing the slit 18, they can be fitted into a pair of holes 43, 44 in a female portion main body 42 of a snap-fit ​​female component 41, which will be described later.

[0023] The snap-fit ​​female member 41 is made of resin, and has holes (female portions) 43, 44 formed in a female portion body 42 that can fit into insertion holes 46 through which the claw portions 13, 14 of the snap-fit ​​male member 11 are inserted. The other end of the female portion body 42 having the holes 43, 44 has an elongated hole 45 through which the locking portion 32 of the personal accessory locking member 31 is inserted.

[0024] A light source protection part 25 that forms an accommodation chamber 24 that accommodates the LED lamp 21 is formed on one surface of the snap-fit ​​female member 41. The LED lamp 21 is accommodated inside the light source protection part 25. A power supply for the LED lamp 21 (not shown) is provided inside the light source protection part 25, and a switch 22 that can switch the power supply on and off is provided on the underside of the light source protection part 25. The switch 22 switches the LED lighting on and off. A front surface 251 of the light source protection part 25 is made of a light-transmitting resin.

[0025] When the lighting fixture 1 of this embodiment is fitted to the neck of a plastic bottle, as shown in Figures 7 to 10, the claws 13 and 14 extend away from the shoulder 4 due to the inclined portion 19 that bends from the fitting portion 17, so that the front surface 251 of the light source protection portion 25 faces the transparent conical shoulder 4 of the plastic bottle 2 in a non-contact state. As a result, light emitted by the LED lamp 21 passes through the light source protection portion 25 and illuminates the transparent shoulder 4 and the outer wall of the bottle body 5 of the plastic bottle. At this time, the light is diffused by the liquid in the plastic bottle, the transparent shoulder 4, and the bottle body 5, and the plastic bottle itself emits light into the surrounding area as if it were a virtual light source with a large volume.

[0026] The personal item fastening member 31 is comprised of a flexible resin belt 36, which is inserted through the elongated hole 45 of the snap-fit ​​female member 41. The belt 36 is bent into a U-shape at the insertion point, and this bent end becomes the connecting portion 33 with the snap-fit ​​female member 41. The other end of the belt 36 forms a fastening portion 32 that can be fastened to a fastening portion, such as a belt loop on pants carried on the body, or a belt loop on a handbag or shoulder bag. The fastening portion 32 forms a fastening portion that can be released from the belt loop by hook-and-loop fasteners 34, 35 affixed to the belt 36. Thus, when the belt 36 is worn on a personal item such as a waist belt or bag, the plastic bottle 2 can be carried via the plastic bottle lighting device 1 of this embodiment. The personal item fastening member 31 also serves as a handle.

[0027] The lighting device 1 for plastic bottles of this embodiment is small, lightweight, and easy to carry by itself, and can be put in a bag, pocket, etc., making it more portable than a flashlight or lantern.

[0028] When necessary, it can be taken out of a bag, pocket, etc. and used as a lighting tool when walking on a dark road and needing a light.

[0029] When carrying the plastic bottle 2, the fitting portion 17 of the snap-fit ​​male member 11 is fitted onto the neck portion 3 of the plastic bottle 2, and the LED lamp 21 on the outside of the bottle body 5 illuminates the plastic bottle 2, emitting bright, diffused light that functions as a large virtual lighting fixture, thereby alerting car and bicycle drivers to the presence of pedestrians and contributing to traffic safety.

[0030] When wearing it on a plastic bottle 2, the fitting portion of the snap-fit ​​male member 11 is fitted to the neck 3 of the plastic bottle 2, and the personal accessory fastening member 31 is fastened to the personal accessory, so that the plastic bottle 2 does not need to be held in the hands, and the person can walk safely even with both hands free. The lighting fixture 1 for plastic bottles is rotatably connected to the neck 3 of the plastic bottle 2.

[0031] The length of the personal item fastening member 31 can also be adjusted. By releasing the claws 13, 14 of the snap-fit ​​male member 11 from the holes 43, 44 of the snap-fit ​​female member 41 at any time while walking, the plastic bottle 2 can be detached and a beverage can be consumed.

[0032] Next, the relationship between different shapes of the shoulder portion of the plastic bottle and the above embodiment will be described.

[0033] FIG. 11 shows Comparative Example 1 in which this embodiment was used on a plastic bottle having a shoulder portion 51 with a so-called angled shoulder shape, and FIG. 12 shows Comparative Example 2 in which this embodiment was used on a plastic bottle having a shoulder portion 52 with a so-called sloping shoulder shape. Comparative Example 1 shown in Fig. 11 has a shoulder portion 51 with a sloping shoulder shape that has an inclination angle α with respect to a plane (reference line) normal to the central axis 28. In contrast, Comparative Example 2 shown in Fig. 12 has a shoulder portion 52 with a sloping shoulder shape that has an inclination angle β with respect to a plane (reference line) normal to the central axis 28. In both Comparative Example 1 and Comparative Example 2, the lighting fixture for a plastic bottle of this embodiment can be used.

[0034] Next, the presence or absence of liquid in the plastic bottle will be described with reference to Figures 13 and 14. The body of the bottle body 5 of the plastic bottle 2 used had two annular irregularities 56 formed around the periphery.

[0035] Figure 13 shows Comparative Example 3 in which this embodiment is used in a plastic bottle 2 containing a liquid beverage 100, with the beverage 100 filling the inside of the bottle so that the liquid level of the beverage 100 is at a high position, and air bubbles 101 are contained in the liquid. In Comparative Example 3, the light emitted from light source 21 is diffused by the shape of bubbles 101 and irregularities 56, and when the bottle is carried while walking, the beverage 100 moves due to vibrations caused by movement, diffusing the light and making the bottle brighter. When a beverage is inside, the light is diffused by hitting bottle body 5, irregularities 56, and shoulder portion 5, providing bright illumination.

[0036] When this lighting fixture is attached to a plastic bottle 2, when light from the LED lamp is irradiated onto the beverage inside the bottle body 5, the light that hits the transparent bottle container and the liquid inside is diffused or scattered, thereby brightly illuminating the surrounding area.

[0037] When the light emitted by the LED lamp shines on the plastic bottle 2, it is diffused by being scattered by the transparent shoulder of the bottle or the liquid inside the bottle, giving the viewer the presence of a luminous object of the same volume as the bottle and serving as a safety light at night.

[0038] FIG. 14 shows Comparative Example 4 in which this embodiment is used on an empty plastic bottle 2 that does not contain any liquid beverage.

[0039] In Comparative Example 4, the beverage was empty, and the light was diffused by hitting the bottle body 5, the irregularities 56, and the shoulder portion 5, providing bright illumination to the same extent as when the beverage was filled.

[0040] In this embodiment, regardless of whether or not there is a drink in the plastic bottle, when walking down a dark street, turning on the selector switch 22 reflects the light of the LED lamp 21 through the front of the storage compartment 24, off the transparent shoulder 4 on the outer wall of the plastic bottle 2, and also off the liquid if there is any. The plastic bottle itself emits light like a large, virtual light source, illuminating the surrounding area. This alerts drivers of cars, motorcycles, and bicycles on the road and increases the safety of pedestrians. It can also be used for walking, running, camping, and during disasters.

[0041] The lighting fixture 1 for plastic bottles includes a fitting portion 17. This allows the fitting portion 17 to be hooked onto the neck portion 3 of the plastic bottle 2 and fixed thereto.

[0042] The lighting device 1 for plastic bottles includes an LED lamp 21 and a changeover switch 22. The changeover switch 22 can be used to switch between on and off. When the changeover switch 22 is turned on, the LED lamp 21 lights up.

[0043] The lighting fixture of this embodiment is highly portable and easy to carry around in a bag because of its small size when not attached to the plastic bottle 2. In addition, a key holder or portable attachment can be attached to one end of the fastening member, improving the convenience of wearing it on the body.

[0044] When used during activities such as walking at night or in the dark, it is useful for people who need to drink constantly when they need light while maintaining the convenience of being able to consume water from a bottle container at any time.

[0045] Unlike during the day, pedestrians are less likely to be noticed by drivers of cars or bicycles in dark places. However, by carrying a plastic bottle 2 equipped with the lighting device in question, pedestrians can not only receive direct light but also diffusely reflected light that is scattered around them. This has the effect of increasing safety by making it easier to notice bumps in the road or obstacles lying on the road. In addition, carrying the lighting device in question has the effect of minimizing damage caused by suspicious individuals.

[0046] The snap-fit ​​male member 11 has an inclined portion 19 extending in a direction away from the shoulder portion 4 of the bottle body 5 between one end of the snap-fit ​​male member and the other end of the snap-fit ​​male member.

[0047] The snap-fit ​​male member 11 and the snap-fit ​​female member 41 of the lighting fixture for plastic bottles can be separated by simple manual operation (see FIG. 6). For example, it can be used by the following procedure.

[0048] (A) When carrying a plastic bottle: (1) The snap-fit ​​male member 11 and the snap-fit ​​female member 41 are separated. (2) The neck 3 of the plastic bottle 2 containing a beverage is passed through the hole 16 of the mating portion 17. (3) The cap 7 is screwed onto the neck 3 of the plastic bottle 2. (4) The locking portion 32 of the personal item locking member 31 is locked onto a lockable portion of clothing on the body or a lockable portion of a bag. When locking, the connection is made by attaching hook-and-loop fasteners 34, 35, for example. (5) The claw portions 13, 14 of the snap-fit ​​male member 11 are engaged with the female portion main body 42 of the snap-fit ​​female member 41.

[0049] (B) When carrying and consuming beverages: (1) The claws 13, 14 are manually bent to separate the claws 13, 14 of the snap-fit ​​male member 11 from the female portion body 42 of the snap-fit ​​female member 41. (2) The cap 7 of the plastic bottle 2 is unscrewed to separate it, and the beverage is consumed. (3) After consuming the beverage, the cap 7 is unscrewed, and the claws 13, 14 of the snap-fit ​​male member 11 are fitted into the holes 43, 44 of the female portion body 42 of the snap-fit ​​female member 41.

[0050] (C) When not carrying a plastic bottle: The claws 13, 14 of the snap-fit ​​male member 11 are fitted into the female body 42 of the snap-fit ​​female member 41 and carried in a pocket or bag. The lighting device can be carried alone whenever needed, such as when walking at night. When the lighting device is separated from the plastic bottle 2 and personal belongings such as a belt or bag, it is small enough to be carried in a bag or similar.

[0051] There is a comparative example of a conventional product in which an LED lighting fixture is attached to the cap of a plastic bottle equivalent to a plastic bottle, but this comparative example must be protected from moisture (liquid).In contrast, the present invention has the advantage that when the bottle cap is closed, moisture is trapped inside the bottle container, so the operation of the lighting fixture is not affected.

[0052] The following solutions can be adopted in the lighting fixture for plastic bottles of the present invention. A changeover switch 22 for switching the LED lamp 21 on and off is provided on one side of the female part main body 42. This allows the LED lamp to be easily switched on and off manually.

[0053] The changeover switch 22 is provided outside the bottle body 5, near the LED lamp 21. This allows the on / off operation of the LED lamp to be unaffected when drinking from the plastic bottle 2.

[0054] The LED lamp 21 is attached to the shoulder 4 of the plastic bottle 2 outside the bottle body 5 without contact. As a result, when the light emitted by the LED lamp 21 shines on the plastic bottle 2, it is diffused by the transparent shoulder 4 of the plastic bottle 2 and by the liquid if there is liquid in the bottle, giving the viewer the presence of a light-emitting body of the same volume as the bottle body 5 and serving as a safety light at night.

[0055] Additionally, the male part 12 of the snap-fit ​​male component 11 is made of resin and employs a means having a pair of claws 13, 14 and a slit 18 that allows the claws 13, 14 to bend. As a result, when the pair of claws 13, 14 are pressed manually, the elasticity of the resin allows the snap-fit ​​male component 11 to be easily attached to and detached from the holes 43, 44 of the snap-fit ​​female component 41 with a comfortable, controlled feel.

[0056] Furthermore, the snap-fit ​​male member 11 employs a means having a sloped portion 19 between the mating portion 17 and the male portion 12 that extends in a direction away from the transparent shoulder portion 4 of the plastic bottle 2. As a result, the position of the light source 21 is such that it does not interfere with the shoulder 5 regardless of the shape of the shoulder of the plastic bottle 2, and the center of the light source is located below the neck 3 in the direction of gravity. Even if the position of the light source 21 is slightly displaced, it remains out of contact with the shoulder 5, facing it, and does not adversely affect the light diffusion effect.

[0057] Therefore, if there is liquid in the plastic bottle 2, the light from the LED lamp 21 is diffused by the liquid, the transparent shoulder 4, and the bottle body 5, and the plastic bottle 2 itself emits light into the surrounding area as if it were a virtual light source with a large volume, illuminating the surrounding area. This alerts drivers of cars, motorcycles, and bicycles on the road and increases the safety of pedestrians. It can also be used for walking, running, camping, and during disasters.

[0058] Second Embodiment A second embodiment of the present invention will be described with reference to FIGS.

[0059] In the second embodiment, the fitting portion 17 of the snap-fit ​​male member 11 of the first embodiment has a second pair of claws 53, 54 instead of the hole 16. The second claws 53, 54 are flexible and are configured to be able to fit into the female portion of a second snap-fit ​​female member (not shown) that fits into the neck of a plastic bottle (not shown). The plastic bottle to which the present invention is applied may have any shape. The design of the plastic bottle is not limited to the shape shown in the drawings, and may have irregularities, slits, patterns, etc.

[0060] As described above, the present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the spirit and scope of the present invention. [Explanation of symbols]
