Description

[Technical field]

[0001] The present invention relates to a cover for preventing the spray emitted from the spray nozzle from scattering and soiling areas other than the hair when using hair styling sprays and hair color sprays (hereinafter collectively referred to as "hairsprays") used for styling and dyeing hair, and other sprays for other purposes. In the following, the term "spray" refers to a filler such as a hair styling agent or hair dye contained in the sprayer being sprayed from the nozzle of the sprayer together with compressed gas also contained in the sprayer, resulting in a mist of the filler. [Background technology]

[0002] Hairspray allows you to easily maintain your hairstyle for a long time at home without having to go to a beauty salon or barber, and to give your hair shine and volume. Hair color sprays are also used when you want to dye your hair temporarily, such as for dyeing gray hair or for fashionable purposes. In this way, hairspray is a very convenient cosmetic product that can be used daily by both men and women, as it does not require you to spend a lot of time or money on styling or dyeing your hair.

[0003] Hairsprays for everyday use contain liquefied or compressed gases such as LPG or dimethyl ether as propellants in pressure-resistant containers, as well as copolymers, glycerin, other moisturizers, antibacterial agents, surfactants, and ethanol as a solvent. Hairsprays are filled with a liquid mixture of aerosols, concentrate, and solvent (hereafter referred to as "filler") containing these ingredients and are under internal pressure. The nozzle is made wide so that the filler can be dispersed. When the spray button on the hairspray is pressed, the closed valve is released and the filler contained in the can is sprayed out in a mist with great force.

[0004] When hairspray is sprayed evenly over the entire head of hair, it is sprayed from a position about 20 cm away from the head, so the filler under internal pressure is dispersed forcefully from the nozzle, and the spray splashes not only onto the hair but also over a wide area around it, often soiling the surrounding area such as tables, dressing tables, and makeup tables, or getting on the wearer's own clothes, or even on the face, neck, etc.

[0005] Removing filler from furniture, clothing, etc. is not easy, and in many cases it cannot be removed completely. In particular, as mentioned above, fillers contain many ingredients that are harmful to the human body, and the fillers that are sprayed with force can be inhaled into the body through the mouth or nose. If they get into the eyes, they can cause pain, and if too much of the spray gets on the forehead or skin, it can cause symptoms such as clogged pores, itching, and rough skin. Furthermore, fillers contain flammable ingredients, so if they are sprayed over a wide area, they can cause a fire.

[0006] Therefore, when using hairspray, it is common to take precautions to prevent this from happening by laying old newspapers or cloth around the area, removing anything that may ignite, wearing clothes that you don't mind getting dirty, wrapping a towel around your face, and covering your shoulders with a cape. However, such preparation requires a certain amount of effort and makes it difficult to style or dye your hair. In addition, there are cases where suitable clothes or capes that can be stained are not available, and even if there are, it is time-consuming and troublesome to wear them every time. Furthermore, wrapping a towel around the face is not only time-consuming, but it can also cover the mouth and nose, making it difficult to breathe, or covering the eyes and blocking the view of the head, making it impossible to spray the spray on the intended area and causing it to splash over a wide area.

[0007] Therefore, Patent Documents 1 and 2 disclose a method of using hairspray without covering the surroundings, wearing soiled clothes or a cape, or wrapping a towel around the face. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2005-040472 A [Patent Document 2] Utility Model Registration No. 3125564 Summary of the Invention [Problem to be solved by the invention]

[0009] The method disclosed in Patent Document 1 above involves covering the face with a flexible, transparent plate or film when using hairspray. Although this method can protect the face from the spray emitted from the hairspray, it cannot prevent the spray from scattering around or adhering to clothing, etc. In addition, the method disclosed in Patent Document 2, like Patent Document 1, involves covering only the face with a cover made of plastic or rubber material, and therefore cannot prevent the particles from scattering in the surrounding area or adhering to clothing, etc.

[0010] Therefore, the present invention provides a cover that does not cover only the face as disclosed in the above prior art documents, but uses a shatter-proof cover made of a flexible sheet-like material and shaped like a hollow inverted truncated cone with open top and bottom, which prevents the spray sprayed from the hairspray from scattering from the space formed by the cover, thereby preventing the spray from scattering onto the body and surroundings other than the hair without requiring excessive effort.

Effect of the Invention

[0028] The spray splash prevention cover of the present invention makes it possible to prevent spray from splashing onto the face, other exposed skin, or clothing when spraying hairspray onto the hair, without the need to take the time to cover the face with a towel or wear old clothes or a cape, thereby preventing the inhalation of harmful fillers or the filler from sticking to clothing. In addition, you can easily style or dye your hair without having to take the time to lay old newspapers or cloth around it or move anything that could catch fire. In addition, by attaching a partial spray device, it is possible to style, dye, or paint only a portion of the hair, such as the hairline or sides of the head, a different color. In addition to styling and dyeing hair, it is also possible to place the object to be sprayed inside the spray-scattering prevention cover of a spray equipped with a partial spray device and color the object without spray scattering. In addition, since the protective cover can be distributed in a folded, compact state, transportation costs and display costs can be reduced. Furthermore, when plastic is used as the flexible sheet-like material, the spray filler adhering to the protective cover can be easily washed off, so that it can always be used in a clean condition.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a spray splash prevention cover according to the present invention will be described with reference to the drawings.

[0031] <Embodiment of Basic Spray Spray Splash Prevention Cover According to the Present Invention> The basic spray mist prevention cover according to the present invention (hereinafter referred to as "this cover 1") is made of a flexible sheet-like material as shown in Figure 1, and is formed into a hollow, approximately inverted truncated cone shape with top surface 2 and bottom surface 3 open so as to form a so-called mortar shape. In addition, as a common point among the present cover 1 and other types of present covers described below, a flexible material means a material that is flexible and has the property of bending flexibly when an external force is applied, and a sheet-like shape means a shape that is thin and has a longer length in the circumferential direction (i.e., Y direction, hereinafter the same) than in the width direction (i.e., X direction, hereinafter the same). In particular, a plastic material with a thickness of 0.1 mm to 1 mm is suitable. This is because plastic materials make it easy to wash or wipe off the adhering filler, and if the thickness is less than 0.1 mm, the strength is too small for the purpose of the present cover, and conversely, if it exceeds 1 mm, it becomes difficult to form the present cover and is inconvenient to handle.

[0032] As shown in FIG. 2, the cover 1 is held in one hand and moved to the desired position for styling or dyeing the hair, and then the hairspray is held in the other hand with the nozzle facing downward to spray the filler. Normally, hairspray is used about 20 cm away from the head, and the nozzle is designed to disperse the filler, so the spray emitted from the nozzle splashes not only onto the intended head but also onto the surrounding area; however, this cover 1 can prevent this spray from hitting the area and splashing to the surrounding area. In addition, the use of other types of covers including this cover 1, which will be described later, is not limited to hair sprays for styling hair or hair color sprays for dyeing hair, but can also be used to prevent the scattering of sprays emitted from sprays for other purposes used on hair or sprays for purposes other than hair. For example, even when this cover 1 is placed on top of old newspapers or used sheets, an object to be coated is placed inside the cover, and the filler is sprayed from the spray toward the object, the spray that misses the object will hit this cover 1 and prevent it from scattering to the surrounding area.

[0033] If the inclination of the side wall 3a of the cover 1 is too steep, or conversely, too gentle, there is a high possibility that the spray emitted from the hairspray will not remain within the cover 1 but will spread to the surrounding area. Therefore, by setting the ratio of the diameter of the bottom opening 3 of the cover 1 to the diameter of the top opening 2 to 1:2 to 1:2.5, the effect of capturing the spray with the cover 1 and preventing it from scattering to the surrounding area can be improved. Furthermore, if the vertical height 4 of this cover 1 is too low, there is a high possibility that the spray emitted from the hairspray will not remain within this cover 1 but will spread to the surrounding area, and conversely, if it is too high, it will become difficult to style hair, etc. Therefore, by setting the vertical height 4 to 5 cm to 15 cm, this cover 1 is ideal for use in which the cover 1 is held in one hand and the hairspray is held in the other hand to style or dye hair.

[0034] <Embodiments of a spray splash prevention cover equipped with a locking mechanism according to the present invention> The spray splash prevention cover equipped with a locking mechanism according to the present invention (hereinafter referred to as "this cover 5") has a roughly donut-like shape before it is formed, as shown in FIG. 3A(a), in which a flexible sheet-like material is cut away at one point to form a discontinuous portion 6C having two free ends 6A and 6B. In addition, this sheet-like material processed into an approximately donut shape is referred to as annular band 7, and this annular band 7 refers not only to the approximately donut-shaped state before the main cover 5 is formed, but also to the state after the main cover 5 is formed.

[0035] As shown in FIG. 3A(a), the annular band 7 has a pair of locking claw notches 10 (a collective term for the first locking claw notches 10A to the sixth locking claw notches 10F, the same below) formed in the circumferential direction on one side of the discontinuous portion 6C, and a pair of locking grooves 9 (a collective term for the first locking groove 9A to the sixth locking groove 9F, the same below) formed in the circumferential direction on the other side. As shown in Figure 4, a pair of notches 10 for the locking claws are connected to the annular band 7 in the circumferential direction, and the notches are formed in the annular band 7 so that when pressed with a finger, a pair of locking claws 8 (a collective term for the first locking claw 8A to the sixth locking claw 8F, the same applies below) protrude symmetrically at a predetermined interval in the circumferential direction. A pair of locking grooves 9 are formed in the annular band 7 in the circumferential direction as a pair of elongated grooves into which a pair of locking claws 8 are inserted. In the following, unless otherwise specified, the terms "notches for locking pawls," "locking pawls," and "locking grooves" mean "a pair of notches in the circumferential direction," "a pair of locking pawls in the circumferential direction," and "a pair of locking grooves in the circumferential direction."

[0036] As shown in Figures 4(b) and (c), the locking claw notches 10 are pressed with the fingers to protrude the locking claws 8 almost vertically, and as shown in Figure 4(d), the protruding locking claws 8 are inserted into the locking grooves 9. Due to the elasticity of the flexible material, the locking claws 8 open symmetrically in the circumferential direction by themselves, and are locked onto the annular band 7. In this way, the locking claw notches 10 are pressed as if pinching with the fingers to form the locking claws 8, and the mechanism for inserting the locking claws 8 into the locking grooves 9 to lock the locking claws 8 to the annular band 7 is called the locking mechanism. By operating this locking mechanism, the annular band 7, which had a roughly flat doughnut shape with discontinuous parts 6C, becomes three-dimensional while bending in the process of the locking claws 8 being inserted into the locking grooves 9 and locked, and is formed into the main cover 5, which has a hollow, roughly inverted truncated cone shape with the top surface 2 and bottom surface 3 open.

[0037] The locking mechanism is composed of a pair of locking claw notches 10, locking claws 8, and locking grooves 9 in the circumferential direction. Although multiple locking mechanisms are provided in Figures 3A and 3B, the cover 5 can be formed with at least one locking mechanism in the annular band 7. However, because the cover 5 is made of a flexible sheet-like material, if the size of the cover 5 increases, there is a possibility that the cover will lose its shape if only one locking mechanism is used to lock the cover 5. Therefore, in order to stabilize the cover 5 or to make the size of the cover 5, which will be described later, adjustable, two or more locking mechanisms may be provided in the circumferential and width directions as shown in Figure 3(a). Therefore, although six locking mechanisms are provided in Figures 3A, 3B, and 5, the number of locking mechanisms is not limited to six, and the number may be increased or decreased as needed to stabilize the cover 5 or to vary the size. Further, depending on the number of locking mechanisms, the locking mechanisms are appropriately disposed at any positions in the width direction or circumferential direction so that the cover 5 is stably formed.

[0038] 3A(a)-(d) and 3B(e)-(g) show a process in which a substantially doughnut-shaped annular band 7 having a plurality of locking mechanisms is used to form a main cover 5 by operating the plurality of locking mechanisms. An example of a process in which a three-dimensional main cover 5 is formed from a planar substantially doughnut-shaped annular band 7 will be described below with reference to Figs. 3A and 3B. As shown in Fig. 3A(b), the free ends 6A and 6B are moved so that the side of the annular band 7 where the locking claw notches 10 are formed is the outer side and the side where the locking grooves 9 are formed is the inner side, with the discontinuous portion 6C as the boundary, and then the second locking claw notches 10B are pressed to project the second locking claws 8B, and the second locking claws 8B are inserted into the corresponding second locking grooves 9B as shown in Fig. 3A(c). Note that the process in which the locking claws 8 are projected by pressing the locking claw notches 10 is common, so in the following, "projecting the locking claws" will be used to mean the corresponding "pushing the locking claw notches 10 with your fingers as if pinching them, to project the locking claws 8 almost vertically".

[0039] Thereafter, as shown in FIG. 3A(f), the second locking claws 8B inserted into the second locking grooves 9B open symmetrically in the circumferential direction by themselves and are locked to the annular band 7. Note that the locking claws 8 open symmetrically in the circumferential direction by themselves after being inserted into the locking grooves 9 and are locked to the annular band 7, and therefore the description of this part may be omitted below. Also, the locking claws 8 may be inserted into the locking grooves 9 after moving the free ends 6A and 6B so that the side of the annular band 7 where the locking claw notches 10 are formed is the inside and the side where the locking grooves 9 are formed is the outside, with the discontinuous portion 6C as the boundary. Therefore, the positional relationship of the annular band 7 is not particularly specified between the inside and outside of the side where the locking claw notches 10 are formed and the side where the locking grooves 9 are formed, and this is the same below.

[0040] Similarly, as shown in Figures 3A(d) and 3B(e), the first locking claws 8A located above the second locking claws 8B in the width direction are protruded, and the first locking claws 8A are inserted into the corresponding first locking grooves 9A. Then, as shown in Figures 3B(f) and (g), the first locking claws 8A inserted into the first locking grooves 9A open symmetrically in the circumferential direction by themselves and are locked to the annular band 7. This forms a hollow cover 5 having an approximately inverted truncated cone shape with the top surface 2 and bottom surface 3 open.

[0041] Although the second locking claw 8B is inserted into the second locking groove 9B and then the first locking claw 8A is inserted into the first locking groove 9A, the order of insertion is not particularly specified, and the first locking claw 8A may be inserted into the first locking groove 9A first, and then the second locking claw 8B may be inserted into the second locking groove 9B. Furthermore, it is not necessary to activate all of the multiple locking mechanisms every time the cover 5 is used. It is sufficient to activate the multiple locking mechanisms when it is necessary to prevent the cover 5 from losing its shape or when it is necessary to change the size of the cover 5, as described below. The same applies to the process of forming other book covers having locking mechanisms, which will be described below.

[0042] 3A and 3B has a horseshoe shape, the shape is not limited to this shape, and may be rectangular or any other shape as long as the locking claw 8 can be firmly locked to the annular band 7 so as not to make the cover 5 unstable. If the shape of the locking claw 8 is different, the shape of the locking claw notch 10 will also be different accordingly.

[0043] <Embodiment of variable size spray splash prevention cover equipped with locking mechanism according to the present invention> The size of the cover 5 can be changed by using a plurality of locking mechanisms. The case where the size of the cover 5 is changed will be described below with reference to FIG. The cover 5 shown in Figure 5 has the same locking mechanism as the cover 5 shown in Figures 3A and 3B. To make the cover 5 relatively larger, as described above, the free ends 6A and 6B are moved so that the side of the annular band 7 on which the locking claw notches 10 are formed is on the outside and the side on which the locking grooves 9 are formed is on the inside, and then the first locking claw 8A and the second locking claw 8B located closest to one free end 6A are inserted into the first locking groove 9A and the second locking groove 9B located closest to the corresponding other free end 6B, to lock them to the annular band 7.

[0044] On the other hand, to make the size relatively smaller, the first locking claw 8A and the second locking claw 8B which are closest to one free end 6A are inserted into the fifth locking groove 9E and the sixth locking groove 9F which are farthest from the other free end 6B, the third locking claw 8C is inserted into the third locking groove 9C, the fourth locking claw 8D into the fourth locking groove 9D, the fifth locking claw 8E into the fifth locking groove 9E, and the sixth locking claw 8F into the sixth locking groove 9F to be locked to the annular band 7. The order in which the locking claws 8 are inserted into the corresponding locking grooves 9 is not particularly limited, and any of the locking claws 8 may be inserted into the locking grooves 9 first.

[0045] 5, a relatively small size book cover 5 is formed using all six locking mechanisms, but a book cover 5 of a size between the large and small sizes can also be formed, although not shown in the figure. In this case, only four locking mechanisms are used, that is, the first locking claw 8A located closest to one free end 6A is inserted into the third locking groove 9C, the second locking claw 8B into the fourth locking groove 9D, the third locking claw 8C located in the middle in the circumferential direction is inserted into the first locking groove 9A, and the fourth locking claw 8D into the second locking groove 9B, to form a book cover 5 of an intermediate size. 5 is merely an example, and the number of locking mechanisms may be increased or decreased as appropriate. In this case, the number of sizes of the cover 5 that can be changed will also increase or decrease according to the number of locking mechanisms.

[0046] <Embodiments of a spray splash prevention cover having a locking mechanism formed in a folded state according to the present invention> An example of the process in which the folded state is unfolded into a doughnut shape and then the three-dimensional book cover 5 is formed will be described below with reference to FIG. As shown in FIG. 6, the cover 5 can be made compact by providing any number of widthwise folds 25 at any circumferential position of the annular band 7, and folding the annular band 7 at the folds 25. In Fig. 6, the annular band 7 has three folds 25, and in Fig. 6(a), the annular band 7 is folded at all three folds 25, resulting in the most compact state of the cover 5. From this state, the band is unfolded through the processes shown in Figs. 6(b)-(f) into a roughly doughnut shape as shown in Fig. 6(g). The process of forming the cover 5 thereafter is the same as that described above. Note that, although the annular band 7 has three folds 25 in Fig. 6, this number is not necessarily limited, and the unfolding process shown in Fig. 6 is merely an example, and the unfolding process will differ if the position and number of folds 25 and the folding method when folded most compactly are different.

[0047] The three-dimensionally formed main cover 5 can be folded into a compact state at the crease 25 provided in the annular band 7. This improves convenience by allowing the cover to be stored in a compact state when not in use and the cover to be formed when in use. In addition, by placing the cover in a compact state during the distribution process, it is possible to reduce transportation and display costs and improve economy.

[0048] <Embodiments of a spray splash prevention cover for a spray having a partial spray device according to the present invention> An embodiment of a spray splash prevention cover (hereinafter referred to as "this cover 19") for a spray having a partial spray device according to the present invention will be described below. As shown in Fig. 7, the main cover 19 has a partial spray device 11 attached to the bottom opening 3 (shown in Fig. 11A(b), the same below) of an annular band 20 that is made of the same material and has the same shape as the annular band 7 of the main cover 5. The material of this partial spray device 11 is not particularly specified, and any material may be used as long as the function of the partial spray device 11 is fully exhibited. For example, it may be the same material as the main cover 19.

[0049] The method of attaching the partial spray device 11 to the annular band 20 is not particularly limited, and any method, such as adhesive, tape, or the like, may be used as long as the partial spray device 11 does not easily come off the annular band 20. As shown in Figure 8, the partial spray device 11 is hollow and has an approximately inverted truncated cone shape with an open top and is made up of a side plate 12 and a bottom plate 13. The shape and size of the bottom plate 13 are approximately the same as the shape and size of the bottom opening 3 of the annular band 20, and the inclination angle of the side plate 12 is also approximately the same as the inclination angle of the annular band 20. With this structure, the partial spray device 11 fits into the bottom opening 3 of the annular band 20, so the spray emitted from the spray does not leak out from this attachment.

[0050] As shown in Figure 8, the bottom plate 13 of the partial spray device 11 is provided with openings 14 (openings (a) to (c)) of any shape. In Figure 8, three openings (a) 14A to (c) 14C with different shapes are provided, but the number of openings 14 is not limited to three and may be two or more. Furthermore, the shape of the openings 14 may be determined arbitrarily, and may be a shape suited to each application, such as when the filler in the hairspray is to be sprayed only on small areas such as the front or sides of the hair, or when a portion of the hair is pulled out through the opening and the filler in the hairspray is to be sprayed thereon. 8 to 11B, the bottom plate 13 is provided with a closing portion 15 as a predetermined area with no openings other than the opening 14. This closing portion 15 is necessary when the cover 19 is used for purposes other than hair styling, which will be described later. Note that this closing portion 15 is not necessarily required, and when the cover 19 is not used for purposes other than hair styling with hairspray or hair dyeing, an opening may be provided at the closing portion 15, and the bottom plate 13 may have no closing portion.

[0051] The partial spray device 11 is provided above the bottom plate 13 with a slide plate 16 for opening and closing any one of two or more openings 14 formed in the bottom plate 13 or for selecting a closing portion 15. The slide plate 16 may be provided below the bottom plate 13. The material of the slide plate 16 is not particularly limited as long as it satisfactorily functions as the slide plate 16. For example, the slide plate 16 may be made of the same material as the main cover 19. The slide platen 16 has a sector shape in plan view with a portion of a circle missing, and the arc of the sector has the same radius of curvature as the arc of the bottom plate 13. In the following description, the portion missing the circle, i.e., the portion defined by the two notch lines 17 and the arc of the bottom plate 13 between them, will be referred to as the "notch portion." In addition, the slide plate 16 and the bottom plate 13 share a common central axis 18, and the slide plate 16 can be rotated above the bottom plate 13 around this central axis 18, or downward if the slide plate 16 is provided below the bottom plate 13, and the position of the cutout portion moves in conjunction with this.

[0052] The slide plate 16 shown in Figures 7 to 12 has a cutout portion that is approximately 1 / 4 of a circle missing, but the size of the cutout portion may be changed depending on the shape, number, and arrangement of the openings, or the size and presence or absence of the closing portion. As shown in Fig. 9, the slide plate 16 is rotated about a central axis 18 to move the cutout portion to the opening portion 14 or the closing portion 15 depending on the application. For example, in Fig. 9(a), the slide plate 16 is rotated so that the cutout portion moves to the opening portion (b) 14B, in Fig. 9(b), the slide plate 16 is rotated so that the cutout portion moves to the opening portion (c) 14C, and in Fig. 9(c), the slide plate 16 is rotated so that the cutout portion moves to the closing portion 15.

[0053] Specific methods of use include, for example, pulling a portion of hair through opening 14 and coloring that portion in a streak, so-called mesh dyeing, as shown in Fig. 10(a), or styling the hairline at the forehead, as shown in Fig. 10(b), by rotating slide plate 16 so that the notch selects opening 14 according to the purpose, and then spraying the hairspray filler while holding and abutting cover 19 so that the selected opening 14 is positioned at the desired part of the hair. The spray from the spray hits cover 19 and hardly scatters around.

[0054] <Embodiments of a spray splash prevention cover equipped with a locking mechanism, a fastening mechanism, and a partial spraying device according to the present invention> The spray splash prevention cover (hereinafter referred to as "this cover 21") equipped with the locking mechanism, the fastening mechanism, and the partial spraying device according to the present invention has a generally doughnut shape before it is formed, as shown in Fig. 11A(a), in which a flexible sheet-like material is cut off at one point to form a discontinuous portion 6C having two free ends 6A and 6B. This sheet-like material processed into a generally doughnut shape is called annular band 22. This annular band 22 refers not only to the generally doughnut-shaped state before this cover 21 is formed, but also to the state after this cover 21 is formed.

[0055] 11A(a), the annular band 22 has a pair of locking claw notches 10 (a collective term for the first locking claw notches 10A to the fourth locking claw notches 10D, the same below) on one side of the discontinuous portion 6C, and a pair of locking grooves 9 (a collective term for the first locking groove 9A to the fourth locking groove 9D, the same below) on the other side. The structure of the locking mechanism consisting of a pair of locking claws 8 (a collective term for the first locking claw 8A to the fourth locking claw 8D, the same below) that protrude symmetrically at a predetermined interval in the circumferential direction by pressing the locking claw notches 10, the locking groove 9 and the pair of locking claw notches 10 with a finger is the same as that of the cover 5. Therefore, by operating the locking mechanism, the flat, roughly donut-shaped annular band 22 is transformed into a three-dimensional, hollow, roughly inverted truncated cone-shaped cover 21 with open top surface 2 and bottom surface 3, which is the same as cover 5, so explanation is omitted.

[0056] As with the cover 5, the cover 21 can be formed with at least one locking mechanism in the annular band 22. However, in order to stabilize the cover 21 or to make the size variable, two or more locking mechanisms may be provided in the circumferential and width directions as shown in Fig. 11A(a). Thus, although four locking mechanisms are provided in Fig. 11A and Fig. 11B, the number of locking mechanisms is not limited to four, and may be increased or decreased as appropriate to stabilize the cover 21 or depending on the number of sizes to be changed. Further, depending on the number of locking mechanisms, the locking mechanisms are appropriately disposed at any positions in the width direction or circumferential direction so that the cover 21 is stably formed. Although the shape of the locking claw 8 shown in Figures 11A and 11B is a so-called horseshoe shape, it is not necessarily limited to this shape and may be rectangular or another shape, similar to the locking claw 8 of this cover 5. Furthermore, if the shape of the locking claw 8 is different, the shape of the locking claw notch 10 will also be different accordingly.

[0057] Next, the process in which the partial sprayer 11 is attached to the annular belt 22 by the fastening mechanism will be described with reference to Figs. 11A to 12. As shown in FIG. 11A(a), the annular band 22 is provided with narrowing claw notches 24 (a collective term for first narrowing claw notches 24A to fourth narrowing claw notches 24D, the same below) in the circumferential direction. As shown in Fig. 12, the upper part of the clamping claw notch 24 is connected to the annular band 22, and a notch is formed in the annular band 22 so that the clamping claws 23 (a collective term for the first clamping claw 23A to the fourth clamping claw 23D, the same applies below) are protruded to the inside of the annular band 22 when pressed with a finger. The clamping claw notch 24 and the clamping claws 23 are collectively referred to as a clamping mechanism. The partial sprayer 11 is clamped to the annular band 22 using this clamping mechanism.

[0058] The mechanism for fastening the partial sprayer 11 to the annular band 22 using the fastening mechanism is as follows: as shown in FIG. 12, the fastening claw notch 24 is pressed with a finger to slightly protrude the fastening claw 23, and the upper edge of the side plate 12 of the partial sprayer is inserted into the gap created between the annular band 22 and the fastening claw 23 while the finger is then released from the fastening claw 23; then, due to the elasticity of the flexible material, the fastening claw 23 returns by itself to its original position, i.e., toward the annular band 22, so as to pinch the upper edge of the side plate 12 and hold it against the annular band 22. The fastening mechanisms are formed at a plurality of locations and are operated in the same manner as above, thereby making it possible to fasten the partial spray device 11 to the annular band 22. Since the structure and function of the partial spray device 11 are the same as those of the main cover 19, a description of the structure and function thereof will be omitted below.

[0059] In Figures 11A and 11B, multiple fastening mechanisms are provided, but the formation positions of the fastening mechanisms in the width direction are determined so that the partial spray device 11 is placed at the bottom opening 3 of the annular band 22, and the positions of the multiple fastening mechanisms in the width direction are all the same. If there are at least two fastening mechanisms in the annular band 22, the partial sprayer 11 can be fastened to the annular band 22. However, it is better to provide a plurality of fastening mechanisms in the circumferential direction in order to stably fasten the partial sprayer 11 to the annular band 22. Therefore, although four fastening mechanisms are provided in Figures 11A and 11B, the number of fastening mechanisms is not limited to four, and it is sufficient if there is a number that can securely fix the partial sprayer 11 without it falling off.

[0060] 11A(a) to 11B(f) show an example of a process in which the partial spray device 11 is clamped to the annular band 22 having a plurality of clamping mechanisms. The process in which the partial spray device 11 is clamped to the annular band 22 will be described with reference to Figs. 11A and 11B. As shown in FIG. 11A(b), first, the annular belt 22 is formed into a hollow, generally inverted truncated cone shape with the top surface 2 and bottom surface 3 open, and then the partial spray device 11 is attached to the annular belt 22. As shown in FIG. 11A(c), the partial spray device 11 is moved to the bottom opening 3 of the annular band 22, and as shown in FIG. 11B(d), the upper edge of the side plate 12 is clamped by the fourth clamping claw 23D to be held against the annular band 22. Thereafter, as shown in FIG. 11B(e), the second clamping claw 23B, which is located opposite the fourth clamping claw 23D, clamps the upper edge of the side wall 12 and presses it against the annular band 22, and further, as shown in FIG. 11B(f), the first clamping claw 23A and the third clamping claw 23C, which are located in a direction perpendicular to the imaginary line connecting the second clamping claw 23B and the fourth clamping claw 23D, clamp the upper edge of the side plate 12 and press it against the annular band 22, thereby clamping the partial sprayer 11 to the annular band 22. The order in which the upper edge portions of the side plates 12 are clamped to the clamping claws 23 as described above is not particularly limited, and they may be clamped in any order.

[0061] <Embodiment of the present invention in which the size of the spray splash prevention cover of the spray equipped with the locking mechanism, the fastening mechanism, and the partial spraying device is variable> The size of cover 21 can be changed by activating multiple locking mechanisms, similar to cover 5. As shown in Figures 11A and 11B, four locking mechanisms are formed in annular band 22, and with multiple locking mechanisms thus formed in the circumferential direction, the size of cover 21 can be changed. 11A and 11B are merely examples, and the number of locking mechanisms shown in the figures may be increased or decreased as appropriate. The specific method for changing the size is the same as for the cover 5.

[0062] <Embodiments of the spray splash prevention cover having a locking mechanism, a fastening mechanism, and a partial spraying device formed in a folded state according to the present invention> The process in which the main cover 21 is unfolded from a folded state into a substantially doughnut shape and then the three-dimensional main cover 21 is formed will be described. In the present cover 21, similarly to the present cover 5, any number of widthwise folds can be provided at any circumferential position of the annular band 22, so that the annular band 22 can be folded at those folds to make the present cover 21 compact. As with the present cover 5, the number and positions of the folds are not specified. The process in which the annular belt 22 is unfolded from a folded state into a substantially doughnut shape is the same as that of the present cover 5. Moreover, the procedure for attaching the partial spray device 11 to the annular belt 22 unfolded into a substantially doughnut shape is as described above.

[0063] <Embodiments of the spray splash prevention cover of the spray equipped with the partial spray device according to the present invention when used for purposes other than hairspray> The main cover 19 and the main cover 21 (hereinafter referred to as "the main cover 19, etc.") equipped with the partial spray device 11 are mainly used for hair styling and hair dyeing, but can also be used for purposes other than hair styling, etc. An embodiment for use other than hair styling, etc. will be described with reference to Fig. 13. The partial sprayer 11 attached to the main cover 19, etc., is formed with a closing portion 15 in addition to the opening 14. By moving the cutout portion of the slide plate 16 to this closing portion 15, the partial sprayer 11 does not have any openings, and the main cover 19, etc. is formed as a hollow vessel having a roughly inverted truncated cone shape with the partial sprayer 11 as the base plate. When an object 26 to be coated is placed on the cover 19 or the like formed as a container and various spray fillers are sprayed toward it, any spray that misses the object 26 to be coated hits the cover 19 or the like, preventing the spray from scattering to the surrounding area. In this way, even when the cover 19 or the like is used for purposes other than hair styling, it is possible to prevent the spray from scattering around.

[0064] <Embodiment of spray scattering prevention cover provided with a hook part according to the present invention> With reference to FIG. 14, an embodiment of a main cover 1, a main cover 5, a main cover 19, and a main cover 21 (hereinafter referred to as "main cover 1, etc.") provided with a hook portion will be described. A hanging portion 27 may be provided at any position on the periphery of the upper opening 2 of the cover 1, the annular belt 7, the annular belt 20 or the annular belt 22 so that the cover 1 etc. can be hung on a wall or the like when not in use. In Fig. 14, the shape of the hook 27 is horseshoe-shaped, but it is not limited to this shape and may be hook-shaped, annular, or other shapes. Also, in Fig. 14, there is only one hook 27, but the number of hooks is not particularly limited and multiple hooks may be provided. [Industrial Applicability]

[0065] As described above, the invention of the present application is suitable for providing a spray splash prevention cover that allows for easy styling or dyeing of hair, without the need for the effort required to prevent the spray from splashing, such as covering the face with a towel when spraying hairspray, wearing old clothes or a cape, laying old newspapers or cloth around the area, or moving anything that may ignite.
