Description

[Technical field]

[0001] The present invention relates to a portable container for liquid cosmetics such as perfume, which can be sprayed or applied directly to the skin. [Background technology]

[0002] In order to easily use liquid cosmetics such as perfume or liquids such as moisturizers (hereinafter simply referred to as cosmetic liquids) on the go, there are small portable bottles that can be carried around with cosmetic liquid inside, and some of them are equipped with a spray device for convenience when using them (see, for example, Patent Document 1 and Patent Document 2).

[0003] These portable containers with spray devices spray the cosmetic liquid stored inside by pressing the pressing part on the head and using the force of the pressing. The pressing part is pressed the first time, and as the pressing part returns it draws up the cosmetic liquid using the principle of a dropper. When the pressing part is pressed a second time the drawn up cosmetic liquid is sprayed from the spray hole. No gas cylinders or the like are used for spraying, making it simple, small, lightweight and convenient to carry.

[0004] In addition, with the above-mentioned spraying method, the cosmetic liquid is not only sprayed at the targeted location but also sprayed into the air, so if you use perfume, etc., people around you may notice that you have used the cosmetic liquid, some cosmetic liquid may be wasted, and some places may be hesitant to spray perfume.Therefore, there are also devices that apply cosmetic liquid such as perfume directly to the skin using a ball that rotates freely in all directions without spraying (for example, see Patent Document 3 and Patent Document 4).

[0005] The above-mentioned application type is a type in which a porous body such as felt is soaked in cosmetic liquid, and a ball that is in contact with the felt on the inside and exposed to the outside on the other side is pressed against the skin and rolled to apply the cosmetic liquid directly to the skin.

[0006] Depending on the time and place, there are times when it is more convenient to use the product by spraying and times when it is more convenient to use the product by applying it, and the applicant has also proposed a portable cosmetic liquid container that can be used in both spray and application modes with a single container (see Patent Document 5). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 4070512 [Patent Document 2] Utility Model Registration No. 3098395 [Patent Document 3] Japanese Utility Model Application Publication No. 5-35008 [Patent Document 4] Utility Model Registration No. 3010117 [Patent Document 5] Patent No. 7026337 Summary of the Invention [Problem to be solved by the invention]

[0008] The invention of Patent Document 5 mentioned above combines a spray type and an application type portable container into one compact, easy-to-carry container that can be used depending on the time and place. In addition, since both spray type and application type cosmetic liquids are used in the same container, the cosmetic liquid only needs to be refilled once, and regardless of which method is primarily used, the cosmetic liquid in the container can be used up to the fullest.

[0009] However, in the configuration of the portable cosmetic liquid container of Patent Document 5, the application mechanism used in the application type has a partition plate that separates the inside of the cylindrical main body from the inside of the application mechanism plate, and this partition plate has a cylindrical portion that protrudes into the inside of the application mechanism plate and a protrusion that is conductive to the cylindrical portion, protrudes from the partition plate into the inside of the cylindrical main body, and has a hole that allows liquid to pass through. A spring that presses a ball outward is fitted on the outside of the cylindrical portion, with one end in contact with the ball and the other end fitted inside the cylindrical portion and the protrusion. Of these, the spring that presses the ball outward is usually made of metal due to the need to generate elasticity.

[0010] Incidentally, most of the components of the portable cosmetic liquid container are made of synthetic resin and can be formed by known injection molding or the like, but if only the spring were to be made of metal, the number of materials required would increase, and manufacturing costs would rise.

[0011] Therefore, an object of the present invention is to solve the above problems and to provide a portable cosmetic liquid container having the same functions as those of Patent Document 5 at low cost. [Means for solving the problem]

[0012] In order to solve the above problems, the invention of claim 1 provides a portable cosmetic liquid container in which one end of a body that is open at both ends and that contains cosmetic liquid is sealed with a spray mechanism that has the function of spraying cosmetic liquid by a pressing action, and the other end of the body is sealed with an application mechanism that has the function of applying cosmetic liquid via a ball exposed to the outside, and the application mechanism is detachable from the body, the application mechanism having a case that holds the ball rotatably in all directions and exposes a part of the ball to the outside, and a partition member that separates the body from the inside of the case, This portable cosmetic liquid container is characterized in that the cutting member has a partition plate, a cylindrical portion protruding from the partition plate toward the inside of the case, and a protruding portion protruding toward the inside of the main body, the cylindrical portion and the protruding portion are conductive to each other, the protruding portion has an opening through which liquid inside the main body passes, a plurality of elastic pieces are formed by making a plurality of slits from the tip side of the cylindrical portion toward the inside, a liquid holder that comes into contact with the ball is enclosed in the cylindrical portion and the protruding portion, and the plurality of elastic pieces and the liquid holder constantly press the ball outward. Effect of the Invention

[0013] According to the above invention, the spray type and application type portable containers are combined into one, making it compact and easy to carry, and both types can be used depending on the time and place. In addition, since both the spray type and application type cosmetic liquids are shared in the same container, the cosmetic liquid only needs to be filled into the container once, and whichever type is mainly used, the cosmetic liquid in the container can be used up sufficiently.

[0014] In addition, in the application mechanism, a number of elastic pieces are formed by a number of slits provided from the tip side of the cylindrical body, and when a ball is pushed into these elastic pieces, the elastic pieces spread outwards to the outside of the cylindrical body, pressing the ball outwards with the force of the elastic pieces trying to return to their original shape; further, the liquid holder enclosed in the cylindrical part and the protruding part also presses the ball, and since the ball is always pressed outwards when the cosmetic liquid is applied, the gap between the case opening and the ball is blocked, and the elasticity of the ball when used for application makes it easy to use.

[0015] Furthermore, since the elastic piece portion that presses the ball can be formed as an extension of the cylindrical body if it has elasticity, it can be made of synthetic resin as a component part, and the entire partition member can be injection molded as a single unit, which eliminates the need to use a metal spring as a member for pressing the ball. As a result, each component part can be made of synthetic resin, the number of parts can be reduced, and low-cost manufacturing is possible. [Brief description of the drawings]

[Figure 7] 1 is a front view showing a portable cosmetic liquid container according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a portable cosmetic liquid container according to the present invention will be described with reference to the accompanying drawings. 1 is a perspective view showing a portable cosmetic liquid container of the present invention, which has a spray mechanism 20 at one end of a cylindrical main body 10 and an application mechanism 30 connected to the other end. Note that the main body 10 does not have to be cylindrical, and may be, for example, a quadrangular prism with a square cross section or a polygonal prism with a cross section of another polygonal shape.

[0018] The main body 10 stores cosmetic liquids such as lotion and perfume inside, and if a transparent material is used, the contents can be seen through and the remaining amount of cosmetic liquid can be checked at a glance, so it is considered to use a transparent synthetic resin or glass for the main body 10, and synthetic resin is preferable from a cost perspective.

[0019] The spray mechanism 20 is of a well-known simple spray structure that does not use a gas cylinder or the like, and a detailed explanation will be omitted, but by pressing a small-diameter columnar pressing part 22, which is freely movable from the outside to the inside in the longitudinal direction, against the base 21, which has the same diameter as the main body 10, first, when returning from the first pressing, the negative pressure generated causes the cosmetic liquid to be sucked up from the inside of the main body 10 through the tube 24 by the action of a dropper, and then, when pressed a second time, the stored liquid is sprayed from the spray hole 23 on the side of the pressing part 22.

[0020] The application mechanism 30 is as shown in the exploded view of FIG. 2, and comprises, from the left side of the figure, a case 31 of the above-mentioned configuration, a ball 32 stored inside the case 31, a liquid holder 33 made of a porous material such as felt or sponge that holds the cosmetic liquid, and a partition member 34 that stores the liquid holder 33 inside and also serves to apply outward pressure to the ball 32.

[0021] The case 31 is composed of a small diameter portion 31a at the tip, a large diameter portion 31c having the same diameter as the main body 10, and a tapered portion 31b between the small diameter portion 31a and the large diameter portion 31c. A part of the ball 32, which is freely rotatable in all directions and which is placed directly against the skin to apply cosmetic liquid, is exposed from the tip of the small diameter portion 31a. To prevent the ball 32 from flying out and to prevent a gap from occurring between the ball 32 and the case 31, a circular tip opening 31d, which is slightly smaller in diameter than the ball 32, is provided, although this is not shown in FIG. 2.

[0022] As shown in Figure 3, the partition member 34 comprises a partition plate 35 sandwiched between the inside of the case 31 and the inside of the main body 10 to separate the two, a cylindrical portion 36 protruding from the partition plate 35 into the inside of the case 31, and a protruding portion 37 protruding into the inside of the main body 10, and the cylindrical portion 36 and the protruding portion 37 are internally conductive to each other.

[0023] In addition, a plurality of slits 36a are formed inward from the tip side of the tubular portion 36 to form a plurality of elastic pieces 36b. When the ball 32 is pushed in from the tip side, the tip side of the slits 36a widens and each elastic piece 36b widens outward. At this time, a force pushing back the ball 32 is generated by the elastic return force of each elastic piece 36b.

[0024] As for the liquid holder 33 contained inside the cylindrical portion 36 and the protruding portion 37 of the partition member 34, since the liquid holder 33 is compressed and sealed inside, a force constantly pushing the ball 32 outward is generated even by the force trying to return it to its original state after compression.

[0025] The elastic piece 36b and the liquid holder 33 act to constantly push the ball 32 towards the tip of the case 31, so that under normal circumstances a gap is created between the tip opening 31d of the case 31 and the ball 32 to prevent the cosmetic liquid from leaking out, and when the cosmetic liquid is applied, the ball 32, which is pressed against the skin and goes inside, is constantly pushed back outwards, realizing smooth application.

[0026] FIG. 4(a) is an enlarged view of the tubular portion 36 shown in FIGS. 2 and 3. The illustrated tubular portion 36 has an S-shaped curve, and three slightly wide slits 36a are provided therein to form three elastic pieces 36b. The upper end of each elastic piece 36b is formed into a spherical curved surface making use of the thickness of the tubular portion 36 so that the tip can receive the ball 32, forming a receiving portion 36c.

[0027] The shape of the tubular portion 36 is not limited to that shown in Figures 2, 3, and 4, the slits 36a may not have a width as shown in the figures but may be more like a notch, and the number of slits 36a and elastic pieces 36b is not limited to three as shown in the figures.

[0028] As another example of the tubular portion 36, Figure 4(b) shows a tubular portion 36 having a tapered shape with four slits 36a and four elastic pieces 36b formed therein, and Figure 4(c) shows a tubular portion 36 having a shape like a cut-off conical head with five slits 36a and five elastic pieces 36b formed therein. The pressing force of the elastic pieces 36b on the ball 32 varies depending on the shape of the cylindrical portion 36 and the number of slits 36a, but the greater the number of slits 36a, the weaker the elastic force (the force pressing against the ball 32).

[0029] FIG. 4(d) shows a cylindrical portion 36 having a number of slits 36a formed by cutting and nicking at the tip thereof to form a number of pleated elastic pieces 36b. This is the same as the case of the cylindrical portion 36 having a plurality of slits 36a formed by cutting and nicking at the tip thereof, in that the elastic pieces 36b spread outward when pressed by the ball 32, and push back the ball 32 by the repulsive force.

[0030] If the force applied to ball 32 is insufficient, there is a risk that the cosmetic liquid will leak out from the gap between ball 32 and tip opening 31d of case 31. Conversely, if the force applied to ball 32 is too great, ball 32 will not rotate smoothly when placed against the skin, causing problems in applying the cosmetic liquid; therefore, the material and shape of cylindrical portion 36, the number of slits 36a formed, and further the material and degree of compression of liquid holder 33 are appropriately adjusted to achieve the optimum pressure.

[0031] Next, protruding portion 37 protruding from partition plate 35 to the opposite side of tubular portion 36 is formed by four pillars 37a standing around an opening communicating with tubular portion 36 via partition plate 35, as shown in Figure 3(b), and is composed of a ring portion 37b connecting the tips of adjacent pillars 37a and a cross portion 37c connecting the tips of opposing pillars 37a to form an opening 37d. Liquid holder 33 protrudes into this protruding portion 37 through tubular portion 36, and the cosmetic liquid in main body 10 can fully come into contact with liquid holder 33 through opening 37d of this protruding portion 37.

[0032] The liquid holder 33 is prevented from falling off into the main body 10 by the pillars 37a, rings 37b, and cross sections 37c that constitute the protruding portion 37, but the structure of the protruding portion 37 is not limited to that shown in the figure and various structures can be adopted, and in short, the shape and other aspects can be adjusted and designed in consideration of the degree to which the cosmetic liquid penetrates the liquid holder 33 from the main body 10 as well as preventing the liquid holder 35 from falling off. For example, the protruding portion 37 may be provided with one or more small holes, and in this case, the number and size of the holes can be determined appropriately in consideration of the degree to which the cosmetic liquid penetrates the liquid holder 33.

[0033] The partition plate 35, tubular portion 36, and protrusion 37 constituting the above-mentioned partition member 34 can all be formed from synthetic resin. In particular, by making the tubular portion 36 from a hard synthetic resin, the elastic piece 36b that pushes the ball 32 can be formed integrally by utilizing the elasticity of the synthetic resin, eliminating the need to use a separate material such as a metal spring.

[0034] The structure of application mechanism unit 30 is as described above. When application mechanism unit 30 is used to directly apply cosmetic liquid to the skin, ball 32 exposed on the surface is pressed against the skin, whereby ball 32 retracts slightly further from tip opening 31d against the force of elastic piece 36b, and ball 32 begins to rotate as it is rolled further over the skin. Inside small diameter portion 31a, the ball surface rotates while in contact with liquid holder 33 impregnated with cosmetic liquid, and the cosmetic liquid is applied to the skin via ball 32.

[0035] In the figure, the liquid holder 33 is shown stored inside the cylindrical portion 36, but this is not limited to this location and it can also be stored inside the tapered portion 31c. In other words, the liquid holder 33 may be filled in the case 31 on the distal side of the partition plate 35.

[0036] The outer periphery of the small diameter portion 31a of the case 31 is provided with a ridge 31e that protrudes continuously in the circumferential direction of the outer diameter of the small diameter portion 31a and has the function of locking a cap 50 described below. The inner diameter side of the large diameter portion 31b is provided with an internal thread (not shown) for detachably joining to the main body 10, and the small diameter portion 31a, tapered portion 31b, large diameter portion 31c and ridge 31d of the case 31 can be molded at one time by integral molding of synthetic resin.

[0037] Next, to complete the portable cosmetic container of the present invention, the spray mechanism 20 and the application mechanism 30 are attached using the external threads 11, 12 at both ends of the main body 10 as shown in FIG.

[0038] The spray mechanism unit 20 is attached to the main body 10 by inserting the tube 24, starting from the external threaded portion 11 side of the main body 10, into the inside, and then screwing the internal thread (not shown) provided on the inner wall of the base 21 into the external threaded portion 11 to attach it.

[0039] The application mechanism unit 30 is attached to the main body 10 by screwing the internal thread (not shown) on the inside of the large diameter portion 31c of the case 31 into the external thread portion 12 of the main body 10, and finally the partition plate 35 of the partition member 34 is sandwiched and fixed at the boundary between the large diameter portion 31c and the tapered portion 31b of the case 31.

[0040] When assembled as described above, the configuration shown in FIG. 6 is obtained. Furthermore, to prevent the pressing portion 22 of the spray mechanism portion 20 from being inadvertently pressed in when carrying the device, and to prevent other objects from touching the ball 32 of the application mechanism portion 30, a first cap 40 is placed over the spray mechanism portion 20, and a second cap 50 is placed over the application mechanism portion 30.

[0041] The cap 50 has a cylindrical body 51 on the inside that is large enough to cover the small diameter portion 31a of the application mechanism part 30, and the inner wall of the cylindrical body 51 is provided with a groove 52 that lightly engages with the protrusion 31e on the small diameter portion 31a when the small diameter portion 31a fits into it.

[0042] The portable cosmetic container of the present invention constructed as described above is as shown in Figure 7. To carry the cosmetic liquid, first remove either the spray mechanism 20 or the applicator mechanism 30 from the main body 10 by rotating the screw in the direction that loosens the screw, then introduce the cosmetic liquid into the container with the opening of the main body 10 facing up, and then screw the spray mechanism 20 or applicator mechanism 30 into the screw portion 11 or 12 of the main body 10 to close the opening.

[0043] In this state, the device can be carried around, and when it is desired to use a cosmetic liquid such as perfume by spraying it, the cap 40 is removed, the spray mechanism part 20 is placed on top, and the pressing part 22 is pressed, so that the cosmetic liquid is sprayed from the spray hole 23.

[0044] On the other hand, when applying the cosmetic liquid directly to the skin, the cap 50 is removed, the application mechanism unit 30 is turned downward, and the ball 32 is rolled while being in direct contact with the skin, thereby applying the cosmetic liquid to the skin.

[0045] In any of the above-mentioned uses, the application mechanism unit 30 is on the bottom side, so that the cosmetic liquid stored in the main body 10 passes through the partition plate 35 in the application mechanism unit 30 by gravity and is replenished into the liquid holder 33.

[0046] On the other hand, on the side of the main body 10 from the partition plate 35, the liquid holder 33 is not present and the cosmetic liquid remains in liquid form, and the cosmetic liquid can be used for spraying until it reaches the lower end of the tube 24 in FIG.

[0047] In addition, the ball 32, which is exposed downward when used for spraying or at other times, is pressed firmly against the tip opening 31d of the small diameter portion 31a by multiple elastic pieces 36b at the tip of the tubular portion 36, thereby preventing leakage of cosmetic liquid from the tip opening 31d.

[0048] Even if cosmetic liquid leaks from the tip opening while the cosmetic liquid is stored in a bag or the like, it remains inside the cylindrical body 51 of the cap 50, so that the inside of the bag or the like is prevented from being soiled without the user's knowledge.

[0049] When the cosmetic liquid inside the main body 10 is used up, the spray mechanism unit 20 or the application mechanism unit 30 is unscrewed from the main body 10 and removed, and the cosmetic liquid is replenished through the opening of the main body 10 (on the external threaded portion 12 side).

[0050] In this embodiment, both the spray mechanism unit 20 and the application mechanism unit 30 can be attached and detached by screws, but if at least the application mechanism unit 30 is made detachable, it is convenient because, for example, when replacing the cosmetic liquid being used with a different one, the liquid holder 33 in the application mechanism unit 30 can also be replaced with a new one.

[0051] As described above, the portable cosmetic liquid container of the present invention has the above-mentioned configuration, and is highly convenient to carry and use as a portable cosmetic liquid container. Most of its components can be manufactured using hard synthetic resin parts, and the partition member in particular can be molded as a single unit while also having the function of pushing the ball, so there is no need to use metal springs, etc., and manufacturing costs can be reduced.

[0052] The configuration of the present invention is as described in the above embodiment, but it goes without saying that the present invention is not limited to the embodiment, and can be implemented by making appropriate design changes within the scope of the object of the present invention.
