Title: Tube for containing curable composition

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to Korean Patent Application No. 20-2021-0003482 filed on Nov. 17, 2021 and all the benefits accruing therefrom under 35 U.S.C. § 119, the contents of which are incorporated by reference in their entirety. 
     TECHNICAL FIELD 
     The present device relates to a tube for containing a curable composition. 
     BACKGROUND ART 
     A curable composition used for nail art may be easily applied to a nail surface because of a high viscosity thereof and produce various designs. However, the curable composition is cured when exposed to ultraviolet light or air to cause inconvenience. Particularly, when the curable composition is cured at a discharged part that is a portion exposed to the outside, the curable composition may not be smoothly discharged to the outside, or a cap may not be separated from a tube. 
     In order to solve the above-described limitations, the related art uses a method of using a composition having a low viscosity, a method of using a composition that is not easily cured, a method of applying a composition onto nails after the composition undergoes a separate curing process, and a method of quickly curing a composition by using a UV lamp. However, the above-described methods require an additional operation and are inefficient in consideration of a treatment time. 
     In recent years, a self nail art industry allowing a user oneself to perform a nail art has been grown. The self nail art represents that a user oneself realizes a nail art image on nails by using a related product instead of visiting a nail shop and receiving a nail art service. As a cost burden paid to a professional nail shop is increased, the self nail art has been popular. 
     In relation to this, although a nail art product having a finished image, which is applied to nails after appropriately processed by a user, is selling in the market, the user may not express a preferred image by oneself. 
     Also, since typical tubes for containing the curable composition are mainly for experts working for nail shops, general consumers may not easily grip the tubes or may not precisely discharge the composition. Thus, the curable composition may be easily cured due to management carelessness of the users to cause usage inconvenience. 
     Thus, a tube for containing the curable composition, which is capable of being easily gripped, easily discharging the curable composition, and preventing the curable composition therein from being easily cured is required to realize a nail art by a user oneself. 
     DISCLOSURE OF THE DEVICE 
     Technical Problem 
     A first object of the present device is to provide a tube for containing a curable composition, which allows a user oneself to easily grip the tube and easily discharge the curable composition, thereby easily realizing a preferred nail art design when the user who is a non-expert realizes the nail art design by oneself in order to solve the above-described typical limitations. 
     A second object of the present device is to provide a tube for containing a curable composition, which allows even a non-expert to easily manage the curable composition by blocking transmission of light and preventing the curable composition from being cured. 
     Technical Solution 
     An embodiment of the present device provides a tube for containing a curable composition, which is coupled with a cap to seal the curable composition for nail art from the outside, including: a body part having a first space therein and extending in a longitudinal direction thereof; a tapering part coupled to one end of the body part, having a second space communicating with the first space therein, and extending in a direction away from the body part along the longitudinal direction; an end part coupled to an end of the tapering part; and a head part comprising: a discharge member coupled to the other end of the body part, which is opposite to the one end, and configured to discharge the curable composition for nail art; and a coupling member coupled with the cap. Here, at least one of the body part and the tapering part includes a layer member having five layers to prevent light or heat from being introduced into the first space or the second space from the outside. 
     In an embodiment, the layer member may include a film layer made of an aluminum containing material. 
     In an embodiment, the head part may be made of a high density polyethylene (HDPE) containing material and black-colored to prevent light including ultraviolet light from being introduced. 
     In an embodiment, the body part may have an outer circumference of 5 mm to 30 mm, and an entire length of the body part and the tapering part may be 50 mm to 150 mm. 
     In an embodiment, the discharge member may allow the first space to communicate with the outside so that the curable composition for nail art is discharged and define an opening having a diameter of 0.5 mm to 3.0 mm. 
     Advantageous Effects 
     The present device allows the user to easily grip the curable composition because the tube has the above-described outer circumference and entire length and allows the user oneself to easily realize the preferred nail art design by easily discharging the curable composition in the tube because the discharge member according to the present device defines the opening having the above-described diameter. 
     The present device effectively prevents the curable composition from being cured in the tube because the layer member having the five layers blocks ultraviolet light transmitted to the inside of the tube and allows the users who are non-experts to easily manage the curable composition.

     MODE FOR CARRYING OUT THE DEVICE 
     Hereinafter, embodiments of the present device will be described in detail with reference to the attached drawings. Note that the same or similar components in the drawings are designated by the same reference numerals as far as possible even if they are shown in different drawings. In the following description of the present device, a detailed description of known functions and configurations incorporated herein will be omitted to avoid making the subject matter of the present device unclear. 
     A tube for containing a curable composition according to an embodiment of the present device is to block transmission of light and effectively prevent the curable composition disposed in the tube from being cured.  FIG.  1    is a perspective view illustrating the tube for containing the curable composition according to an embodiment of the present device.  FIG.  2    is a front view illustrating the tube for containing the curable composition of  FIG.  1   .  FIG.  3    is a side view illustrating the tube for containing the curable composition of  FIG.  1   .  FIG.  4    is a cross-sectional view illustrating the tube for containing the curable composition taken along line A-A′ of  FIG.  1   . 
     As illustrated in  FIGS.  1  to  4   , a tube  1  for containing a curable composition according to an embodiment of the present device includes a body part  100 , a tapering part  200 , an end part  300 , and a head part  400 , and at least one of the body part  100  and the tapering part  200  includes a layer member L 10 . 
     A first space  110  is formed in the body part  100  and extends in a longitudinal direction D 1 . The tapering part  200  may be coupled to one end of the body part  100 , and the head part  400  may be coupled to the other end, which is opposite to the one end, of the body part  100  along the longitudinal direction D 1  of the body part  100 . 
     The first space  110  communicates with a second space  210  that will be described later, and the first space  110  and the second space  210  define the inside of the tube  1  for containing the curable composition. The curable composition is disposed at the inside defined by the first space  110  and the second space  210  and discharged to the outside through the head part  400 . 
     The tapering part  200  is coupled to one end of the body part  100  and extends in a direction away from the body part  100 . The second space  210  is formed in the tapering part  200 . As described above, the second space  210  communicates with the first space  110  and defines the inside of the tube  1  for containing the curable composition together with the first space  110 . 
     A front direction may be a maximum distance between both ends of the tapering part  200  perpendicular to the longitudinal direction D 1 . As illustrated in  FIG.  2   , a width of the tapering part  200  in the front direction may be increased in the direction away from the body part  100 . 
     A side direction may be perpendicular to each of the longitudinal direction D 1  and the front direction. As illustrated in  FIG.  3   , a width of the tapering part  200  in the side direction may be decreased in the direction away from the body part  100 . 
     Since the tube  1  has characteristics in which the width of the tapering part  200  in the front direction is increased in the direction away from the body part  100  (refer to  FIG.  2   ), and the width of the tapering part  200  in the side direction is decreased in the direction away from the body part  100  (refer to  FIG.  3   ), the tube  1  may be easily and conveniently held by hands of a user, and the user may further easily and conveniently may grip the tube  1  for containing the curable composition according to an embodiment of the present device. 
     The end part  300  may be coupled to an end of the tapering part  200 . The end part  300  may extend in a direction away from the tapering part  200 . 
     The head part  400  may be coupled to the other end, which is opposite to the one end, of the body part  100 . The head part  400  may include a discharge member  410  and a coupling member  420 . 
     The discharge member  410  may define a hole for allowing the inside and the outside of the tube  1  for containing the curable composition to communicate with each other. That is, the curable composition may be discharged from the inside to the outside through the hole defined by the discharge member  410 . 
     The coupling member  420  may couple the tube  1  for containing the curable composition with a cap C. As the coupling member  420  is coupled with the cap C, the inside of the tube may be sealed from the outside. Although the coupling member  420  according to an embodiment of the present device has a shape of a thread disposed on an outer surface thereof, the embodiment of the present device is not limited thereto. 
     The coupling member  420  may be a predetermined groove or projection that is physically coupled with the cap C. In this case, a shape of an inner surface of the cap C may correspond to that of the groove or projection of the coupling member  420  when coupled to the coupling member  420 . 
     As illustrated in  FIG.  4   , one of the body part  100  and the tapering part  200  may include the layer member L 10 . The layer member L 10  may have a three to seven layer structure, preferably a three to fifth layer structure. Each of the layers may be made of a polyethylene containing material or include an aluminum film layer L 11  containing an aluminum material. The film layer containing the aluminum material may have a thickness of 7 μm to 17 μm. 
     As at least one of the body part  100  and the tapering part  200  includes the above-described layer member L 10 , light including ultraviolet light or heat may be prevented from being permeated from the outside to the inside of the tube  1  for containing the curable composition. As a result, the curable composition may be effectively prevented from being cured in the tube to increase a use period or convenience. 
     The head part  400  may be made of a material that is black-colored by using a HDPE containing material (HDPE 2700J). As the head part  400  is black-colored by using the HDPE 2700J containing material, light including ultraviolet light may be effectively blocked, and curing of the curable composition, which may be further easily generated inside the head part  400 , may be prevented. 
     Also, an outer circumference of the body part  100  may be a diameter of an outer circumferential surface defined when a cross-section of the body part  100  taken along the direction perpendicular to the longitudinal direction D 1  is viewed along the longitudinal direction D 1 . The body part  100  may an outer circumference of 5 mm to 30 mm, preferably 10 mm to 30 mm, and an entire length obtained by measuring the body part  100  and the tapering part  200  in the longitudinal direction D 1  may be 50 mm to 150 mm, preferably 70 mm to 150 mm in consideration of convenience of realizing a nail art design when a user (particularly, a female user) holds the tube. 
     Since the outer circumference of the body part  100  and the entire length of the body part  100  and the tapering part  200  are provided as described above, the user may easily grip the tube  1  for containing the curable composition to press out the curable composition. 
     Also, the discharge member  410  may define an opening  411 . The opening  411  may communicate the first space  110  or the inside of the tube  1  for containing the curable composition with the outside. When viewed in the longitudinal direction D 1 , the opening  411  may have a diameter of 0.5 mm to 3.0 mm, preferably 0.7 mm to 1.5 mm, more preferably 0.9 mm to 1.3 mm. 
     Since the opening  411  defined by the discharge member  410  has the diameter in the above-described range, the user may easily realize the preferred nail art design by using the curable composition. Since the curable composition is discharged to be extremely thin or thick when the diameter is deviated from the above-described range, users who are non-experts may not realize the preferred nail art design.

Thus, the embodiments of the present device are to be considered illustrative, and not restrictive, and the technical spirit of the present device is not limited to the foregoing embodiment. Therefore, the scope of the present device is defined not by the detailed description of the invention but by the appended claims, and all differences within the scope will be construed as being included in the present device.
