(10) Referring to FIGS. 1 to 4, a tube container equipped with a metal applicator according to an exemplary embodiment of the present disclosure includes a tube body 100, a support body 200, an applicator 300, and an overcap 400.

(11) Contents are contained into the container body (100), on whose upper portion a tube neck 110 having an outlet part 111 that discharges the contents is coupled, and on the center of the outlet part 111 is coupled a discharging hole 111a to which contents contained in the tube container body 100 is discharged.

(12) Regarding to the presently described embodiments, on the lower outer circumferential surface of the outlet part 111 is formed a rotation preventing protrusion 111b which prevents a support body 200 from rotating, and the rotation preventing protrusion 111b, coupled with a coupling groove 211, prevents the support body 200 from rotating and simultaneously guides combining direction when coupling the support body 200 to the outlet part 111.

(13) Meanwhile, it is preferred that a fixing protrusion 111c is formed, encircling the outer circumferential surface, on the outlet part 111 so as to prevent the support body 200 from being separated to upward direction after the support body 200 is coupled.

(14) The support body 200, made of thermoplastic resin, supports an applicator 300, and comprises a passage where the contents discharged through the outlet part 111 flows, and further includes a fixing part 210, a contents movement tube 220, a coupling part 230, and a hollow part 240.

(15) The fixing part 210 is coupled with the outlet portion on the inner lower portion of the support body 200 as encircling the outlet part 111 and fixes the support body 200 to the tube neck 110, wherein a coupling groove is built on the lower portion of the fixing part so as to be able to combine with the rotation preventing protrusion 111b and prevent the support body 200 from rotating.

(16) Furthermore, on the inner lower portion of the fixing part 210 is formed a protrusion 212, which meets the lower end of the fixing protrusion 111c in a state of the protrusion 212 being combined with the outlet part 111 and prevents the support body 200 from moving upward.

(17) The contents movement tube 220 is connected to the outlet part 111, and forms a passage longitudinally, so as to allow the contents discharged through the outlet part 111 to flow to the upper part.

(18) The coupling part 230 is formed with protrusion on the upper end of the support body 200, coupled with an applicator 300 and supports the applicator 300, wherein a securing protrusion 231 is formed, as encircling the outer circumferential, so that the applicator 300 may be secured.

(19) It is preferred that the securing protrusion 231 may have a fluent curve so that the applicator 300 can be attached and separated.

(20) Meanwhile, the support body 200 has a narrow middle portion like an hourglass, wherein with the top end of the support body 200 forming a slope from one side to the other side, the applicator should be built obliquely, providing esthetic effect to the container.

(21) Furthermore, as shown in FIGS. 3 and 4, it is preferred that a hollow part 240 is formed from the upper side and toward the lower side of the support body 200, so that when combined with elastic fit the support body 200 may be pressed, not only enabling to be contracted, but also effectively compensating by the elasticity the difference of the volume change that is caused by the temperature difference and temperature change of the applicator 300 and the support body 200, and thereupon the applicator 300 and the support body 200 are contacted tightly each other all the time and maintain their firmly contacted state.

(22) The applicator 300 is coupled with a coupling protrusion 230 to be able to be attached and separated on the top end of the support body 200, and thereof on the center of the applicator 300, forms a contents discharging hole 310 which allows the contents to move through the contents movement tube 220 to the outside.

(23) According to the present disclosure, the applicator 300 is made of metal, and thus it is possible to deliver heat or cold to the facial skin when applied, resulting in facilitating the metabolism of facial skin and improving the elasticity of the skin.

(24) Furthermore, the applicator 300 is formed in a circular shape in the state of bilateral symmetry with the contents discharging hole 310 in the center, and thereby it is possible to mass-produce with ease through NC manufacturing process and also to reduce expense due to no need of a separate mold.

(25) Furthermore, the applicator 300 can be manufactured through NC manufacturing process, so that it is possible not only to reduce the time required to grind and polish the applicator when post-processing but also to reduce post-processing expense.

(26) Meanwhile, the support body 200 is made of thermoplastic resin and the applicator 300 is made of metal. In this case, since the embodiments of the present disclosure are usually used by contacting the applicator 300 directly to the facial skin after being warm or cool, the support body 200 and the applicator 300 are used under the condition of repeated temperature change.

(27) In this case, the temperature change of metal and thermoplastic resin are varied in size; the coefficient of thermal expansion of metal has a range of 5-25 (unit: x0.000001/ C.), such as brass 18.7, copper 18.0, cast iron 10.8, stainless steel 14.4'7.3, whereas the coefficient of thermal expansion of thermoplastic resin (polymer) is 50600 (unit: x0.000001/ C.), such as polypropylene 100200, polyethylene 200, polystyrene (PS) 70, because thermoplastic resin has weak secondary intermolecular bonds and minimum cross-links. In other words, under the conditions of the same temperature change, the size change of thermoplastic resin is bigger than that of metal, and thereby the difference of size change occurs.

(28) Accordingly, the bonding structure between the support body 200 made of two kinds of material and the applicator 300 may get weaker or be separated, and also the gap between them may arise; thereby, undesirable results such as linkage of contents may occur. To prevent those problems, it is preferred that the outer radius (D1) of the coupling part 231 under the lowest usable temperature should be the same or bigger than the inner radius (D0) of the depression coupling part 320 under the ordinary usable temperature, as shown in FIG. 6.

(29) That is, as described above, when the temperature rises, the support body 200 has bigger size increase according to the temperature change than the applicator 300 (in other words, when the outer radius (D1) of the coupling part 231 according to the temperature rise change gets bigger than the inner radius (D0) of the depression coupling part 320), leading the hollow part 240 to efficiently offset the difference of volume change by elasticity and then despite the temperature change and temperature difference, the applicator 300 and the support body 200 are able to contact each other and maintain combining state.

(30) Meanwhile, when temperature drops, the reduction of the support body 200 is much bigger than that of the applicator 300, and whereupon, the space between the support body 200 and the applicator 300 should arise, and thereby bonding structure may become weaker or separation may occur.

(31) Furthermore, when the applicator 300 touches a user's skin and is used, the applicator 300 having high coefficient of heat conduction gets to the temperature (this is called ordinary usable temperature) of the user's skin with relatively rapid speed, and the size of the applicator increases rapidly, whereas the temperature rise of the support body 200 having low coefficient of heat conduction falls behind, and as a result, the size increase of the support body 200 is delayed, causing the gap between the support body 200 and the applicator 300 to arise, leading to the weakness of the bonding structure and the separation.

(32) As shown in FIG. 6, these problems can be solved by setting the outer radius (D1) of the coupling part 231 under the lowest usable temperature (Generally, this is the temperature on which contents can be kept refrigerated without being deteriorated such as congelation.) to the same or bigger than the inner radius of the depression coupling part 320 under the ordinary usable temperature. Herein, the outer radius (D1) of the coupling part 231 and the inner radius (D0) of the depression coupling part 320 should be measured in the state where they are not coupled and separated respectively, and those measurements should be used.

(33) In other words, when kept refrigerated under the lowest usable temperature, the outer radius (D1) of the coupling part 231 is set to be the same or bigger than the inner radius (D0) of the depression coupling part 320, and thus, always has a bigger measurement than that of the depression coupling part 320 under the same lowest usable temperature.

(34) Meanwhile, while using, even when the applicator 300 rises in relatively rapid speed and the support body 200 is still under the lowest usable temperature, the outer radius (D1) of the coupling part 231 has the same or at least bigger measurement than the inner radius (D0) of the depression coupling part 320.

(35) Hereforth, when both temperatures of the applicator 300 and the support body 200 rise above the lowest usable temperature, then again the outer radius (D1) of the coupling part 231 always gets to have bigger or at least the same measurement than the inner radius (D0) of the depression coupling part 320.

(36) Accordingly, under any temperature change, the outer radius (D1) of the coupling part 231 is at least the same or bigger than the inner radius (D0) of the depression coupling part 320, and therefore, prevents the gap between the support body 200 and the applicator 300 from being generated, leading to preventing bonding structure from being weakened or separated, or fundamentally prevents the contents from being leaked.

(37) Meanwhile, when the outer radius (D1) of the coupling part 231 is always bigger or has the same features (this means when the support body 200 and the applicator 300 are separated, meaning the same as previously described) than the inner radius (D0) of the depression coupling part 320, the support body 20 undergo an elastic deformation by the hollow part 240, with the support body 200 and the applicator 300 under the state of being coupled each other as shown in FIG. 3 or 4; thereby, the outer radius (D1) of the coupling part 231 is made to fit to the inner radius (D0) of the depression coupling part 320, and as a result, the support body 200 and the applicator 300 can be maintained in the state of being coupled tightly.

(38) The overcap 400 encircles the support body 200 and the applicator 300 and is coupled to the tube neck 110, wherein an opening and closing projection 410 is provided with protrusion on the inner top of the overcap 400, so as to enable the contents discharging hole 310 to open and close.
