[0002] like Figure 1 As shown, the existing tubular container may include a container body 11 of a soft material for containing contents, a discharge portion 12 opened at the upper end for discharging the contents in the container body 11, and a shoulder 13 extending from the lower end of the discharge portion 12 and connecting the container body 11 and the discharge portion 12. On the other hand, although Figure 1 Although not shown in the figure, the discharge portion 12 may be further combined with a cap or a nozzle formed with a discharge hole.

[0003] This tubular container is configured such that when a user applies pressure to the outer surface of the container body 11 , the internal pressure of the container body 11 increases, and the liquid is discharged to the outside through the discharge portion 12 or a cap connected to the discharge portion 12 .

[0004] However, in the existing tubular container, such as Figure 2 As shown, when the container body 11 is pressurized, the force generated by the pressurization is transmitted to the discharge portion 12 through the shoulder 13, so that the shape of the discharge portion 12 can be changed from a circle to an ellipse, and there is a problem of leakage of the contents from between the lid and the like combined with the discharge portion 12.

[0005] Therefore, there is a need for a new tubular container that can effectively suppress such deformation of the shape of the discharge portion. Summary of the invention

[0033] Figure 3 is a cross-sectional view showing a content container according to an embodiment of the present invention, Figure 4 Shows the Figure 3 An example of a magnified portion of "A" Figure 5 It is a perspective view showing a content container according to an embodiment of the present invention.

[0034] Reference Figures 3 to 5 , the content container 1000 may include a container body 100 , a discharge portion 200 , and a shoulder 300 .

[0035] The container body 100 forms a storage space inside and stores the contents in the storage space. The container body 100 may have a shape of a tube container with an open upper end and a sealed lower end, but is not limited thereto, and may have various container structures such as a bottle made of a soft material whose volume is reduced by pressurization, an inverted bottle, and the like.

[0036] In an embodiment, at least a portion of the container body 100 may be made of a flexible material. When a user applies external force to the outer surface of the container body 100, the container body 100 is deformed (ie, compressed), and the contents may be discharged to the outside through the discharge portion 200.

[0037] At this time, the contents may include cosmetics, medicines and over-the-counter medicines in liquid, gel, etc. For example, the contents may include: lotion, cream, moisturizing lotion, nutrient lotion, toner, skin softener, toner, astringent, massage cream, nutrient cream, moisturizing cream, whitening essence, brightening cream, sunscreen, sunscreen, sunscreen milk, BB cream, base cream, foundation, CC cream, concealer, blush, shadow, eye shadow, eyebrow pencil, eye cream, etc., but not limited to this, and may include substances of various types or ingredients contained in the container body 100 and discharged to the outside by pressurizing the container body 100.

[0038] The discharge part 200 may be formed at an upper side of the container body 100 to communicate with the container body 100 , and the content may be discharged to the outside through the opened upper end portion.

[0039] In an embodiment, the discharge part 200 may be combined with a cap, a nozzle, a pump, etc. formed with a discharge hole. To this end, at least one coupling portion may be formed on the outer peripheral surface of the discharge part 200. For example, the coupling portion may be a thread, a coupling protrusion, a coupling groove, etc., but is not limited thereto, and various coupling structures may be applicable.

[0040] The shoulder 300 extends downward from the periphery of the lower end of the discharge part 200 to the outside at a predetermined slope to connect the container body 100 and the discharge part 200. By the shoulder 300, a part of the upper end of the container body 100 can be sealed.

[0041] The shoulder portion 300 is formed to have a predetermined thickness, and may be composed of a synthetic resin material that is harder than the container body 100 .

[0042] In an embodiment, the lower end portion of the shoulder 300 may be connected to the upper end portion of the container body 100 by various methods, such as thermal bonding, ultrasonic bonding, bonding using an adhesive, dual injection molding, and the like.

[0043] In an embodiment, at least a portion of the container body 100, the discharge portion 200, and the shoulder 300 may be formed integrally with each other by injection molding, etc. For example, it may be configured that the discharge portion 200 and the shoulder 300 are bonded to the upper end of the container body 100 after being integrally formed by injection molding, etc.

[0044] The deformation suppression groove 310 may be formed concavely inwardly in at least one region of the shoulder 300. When the container body 100 for discharging the contents is pressurized, the deformation suppression groove 310 may suppress the shape deformation of the discharge portion 200. Specifically, when the container body 100 is pressurized, at least one region of the deformation suppression groove 310 contracts or expands, thereby changing the width of the deformation suppression groove 310, thereby preventing the deformation force generated by pressurizing the container body 100 from being transmitted to the discharge portion 200 through the shoulder 300, thereby suppressing the shape deformation of the discharge portion 200. In an embodiment, the maximum depth of the deformation suppression groove 310 may be in the range of 0.8 mm to 2 mm, and the thickness of the region of the shoulder 300 where the deformation suppression groove 310 is formed may be in the range of 0.5 mm to 1.0 mm.

[0045] The deformation suppression groove 310 may be formed at a predetermined interval from the connection portion of the discharge portion 200 and / or the shoulder portion 300 with the container body 100. For example, the deformation suppression groove 310 is formed in a ring shape and may be formed to surround the lower end portion of the discharge portion 200 on the outside while being separated from the lower end portion of the discharge portion 200. In an embodiment, the deformation suppression groove 310 may be formed at a position separated by 3 mm to 10 mm from the connection portion of the shoulder portion 300 with the container body 100 to the inside.

[0046] In order to form the deformation suppression groove 310, the shoulder 300 may include a first bending portion 320, a second bending portion 330, and a third bending portion 340. The first bending portion 320, the second bending portion 330, and the third bending portion 340 are sequentially arranged in the shoulder 300 from the lower end of the discharge portion 200 to the outer side, and the shoulder 300 is bent and deformed with a predetermined curvature around the first bending portion 320 to the third bending portion 340, so that the deformation suppression groove 310 can be formed. For example, the deformation suppression groove 310 can be formed between the first bending portion 320 and the third bending portion 340 so that the second bending portion 330 forms a valley (i.e., the position of the maximum depth).

[0047] In an embodiment, a first inclined surface 311 and a second inclined surface 312 may be formed inside the deformation suppression groove 310. For example, the first inclined surface 311 and the second inclined surface 312 are arranged on both sides of the second curved portion 330 and may extend toward the first curved portion 320 and the third curved portion 340, respectively. Therefore, the deformation suppression groove 310 may have a "V"-shaped cross section. In a state where the container body 100 is not pressurized, the angle between the first inclined surface 311 and the second inclined surface 312 may be in the range of 60 degrees to 120 degrees.

[0048] Figures 3 to 5 The shape of the content container 1000 shown is exemplary, and various shapes can be applied according to the embodiment of the present invention. In addition, according to the embodiment, the content container 1000 includes the container body 100, the discharge portion 200 and the shoulder 300, and can also include additional structures such as a cover and a nozzle.

[0049] Experimental example: Deformation test of container body caused by pressurization

[0050] like Figure 6 As shown, the shoulder and discharge portion ( Figure 6 (a)) and a shoulder and a discharge portion ( Figure 6 Here, the reinforcing rib is used to support the discharge portion on the outside to suppress deformation of the discharge portion.

[0051] Next, a content container was prepared by using the shoulder and the discharge portion according to the present invention (Example 1), and a content container was prepared by using the shoulder and the discharge portion including a plurality of reinforcing ribs (Comparative Example 1), and then, both were subjected to deformation experiments.

[0052] First, refer to Figure 7 When the cap for discharging was combined with the discharge part of Example 1 and Comparative Example 1 respectively and the container body was pressurized, it was confirmed that: in Example 1 ( Figure 7 In (a)), the width of the deformation suppression groove corresponding to the pressurized position of the container body changes, and the shoulder is clearly separated from the lid, but in Comparative Example 1 ( Figure 7 In (b)), the spacing between the shoulder and the lid varies less.

[0053] Next, refer to Figure 8 and the following Table 1, when the container bodies of Example 1 and Comparative Example 1 are pressurized, in Example 1 ( Figure 8 In (a)), the discharge portion is substantially circular, but in Comparative Example 1 ( Figure 8 In (b)), the discharge portion is deformed in shape and becomes an elliptical shape.

[0054] Table 1

[0055]

[0056] Therefore, in the embodiment where the deformation suppression groove is formed, the force (deformation force) generated by the pressurization of the container body acts to deform the width of the deformation suppression groove and limit the transmission to the discharge portion, thereby effectively suppressing the shape deformation of the discharge portion.

[0057] As described above, although the embodiments are described by limited embodiments and drawings, a person skilled in the art can make various modifications and variations from the above description. In addition, each embodiment can be combined with each other according to the requirements. Therefore, other implementation examples, other embodiments and contents equivalent to the scope of the claims also belong to the scope of the attached claims.
