Description

[Technical Field]

[0001] The present invention relates to a content container, and more particularly to a content container that can effectively suppress deformation of a discharge portion. [Background technology]

[0002] As shown in Fig. 1, a conventional tube container may include a flexible container body 11 in which contents are accommodated, a discharge part 12 whose upper end is open to discharge the contents of the container body 11, and a shoulder part 13 extending from the lower end of the discharge part 12 to connect the container body 11 and the discharge part 12. Meanwhile, although not shown in Fig. 1, a cap or a nozzle having a discharge hole formed therein may be further coupled to the discharge part 12.

[0003] Such a tube container is configured so that when a user applies pressure to the outer surface of the container body 11, the inside of the container body 11 rises and the liquid is ejected to the outside through the discharge part 12 or a cap connected to the discharge part 12.

[0004] In the conventional tube container, as shown in FIG. 2, when the container body 11 is pressurized, the force of the pressurization is transmitted to the discharge part 12 via the shoulder part 13, causing the shape of the discharge part 12 to change from circular to elliptical, resulting in problems such as the contents leaking out from between the discharge part 12 and a cap or the like connected to it.

[0005] Therefore, there is a need for a new tube container that can effectively suppress such deformation of the shape of the discharge portion. Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made to solve the above problems, and has an object to provide a content container that can effectively suppress deformation of the discharge portion.

[0007] The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0008] A content container according to an embodiment of the present invention is provided. The content container includes a container body that has a storage space for storing the content formed therein and is pressurized by an external force; a discharge part having an open upper end and configured to discharge the contents by applying pressure to the container body; a shoulder portion extending from the periphery of the lower end of the discharge portion and connecting the discharge portion to the container body; Including, At least one region of the shoulder portion may be provided with a deformation suppression groove that suppresses deformation of the discharge portion when pressure is applied to the container body. [Effects of the Invention]

[0009] According to the present invention, when the container body is pressurized, the transmission of deformation force is limited through the deformation suppression groove formed in the shoulder portion, thereby effectively suppressing deformation of the discharge portion. [Brief explanation of the drawings]

[0025] FIG. 3 is a cross-sectional view of a content container according to an embodiment of the present invention, FIG. 4 is an enlarged view of part A in FIG. 3, and FIG. 5 is a perspective view of a content container according to an embodiment of the present invention.

[0026] Referring to FIGS. 3 to 5, the content container 1000 may include a container body 100 , a discharge portion 200 and a shoulder portion 300 .

[0027] The container body 100 may have a storage space formed therein, and contents may be stored in the storage space. The container body 100 may have the form of a tube container with an open top end and a sealed bottom end, but is not limited thereto, and may have various container structures such as a soft bottle or tottle whose volume decreases under pressure.

[0028] 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 (i.e., compressed), and the contents may be discharged to the outside through the discharge portion 200.

[0029] In this case, examples of the contents include liquid or gel cosmetics, pharmaceuticals, quasi-drugs, etc. Examples of the contents include lotions, milk lotions, moisturizing lotions, nutrient lotions, skin lotions, skin softeners, skin toners, astringents, massage creams, nutrient creams, moisturizing creams, whitening essences, tone-up creams, sunscreens (UV blocking agents), sunscreen creams (sun creams), sunscreen milk (sun milk), BB creams, makeup bases (bases), foundations, CC creams, concealers, blushers (blushers), shading, eye shadows, eyebrow pencils, eye creams, etc., but are not limited to these, and examples include substances of various types or components that can be contained in the container body 100 and discharged to the outside by pressurizing the container body 100.

[0030] The discharge part 200 is formed on the upper side of the container body 100 so as to be in communication with the container body 100, and the contents can be discharged to the outside through the open upper end.

[0031] In the embodiment, a cap or nozzle having a discharge hole, a pump, or the like may be coupled to the discharge part 200. For this purpose, at least one coupling part may be formed on the outer circumferential surface of the discharge part 200. The coupling part may be, for example, a screw thread, a coupling protrusion, a coupling groove, or the like, but is not limited thereto, and various coupling structures may be applied.

[0032] The shoulder portion 300 extends downward at a predetermined incline from the periphery of the lower end of the discharge portion 200 toward the outside, and can connect the container body 100 and the discharge portion 200. The upper end of the container body 100 may be at least partially sealed via the shoulder portion 300.

[0033] The shoulder portion 300 may be formed to have a predetermined thickness, and may be made of a synthetic resin material that is harder than the container body 100 .

[0034] In an embodiment, the lower end of the shoulder portion 300 may be joined to the upper end of the container body 100 by various methods, such as thermal bonding, ultrasonic bonding, bonding using an adhesive, or double injection molding.

[0035] In an embodiment, at least a portion of the container body 100, the discharge portion 200, and the shoulder portion 300 may be integrally formed with one another by injection molding or the like. For example, the discharge portion 200 and the shoulder portion 300 may be integrally formed by injection molding or the like, and then bonded to the upper end of the container body 100.

[0036] At least one region of the shoulder portion 300 may have a deformation suppression groove 310 recessed inward. The deformation suppression groove 310 can suppress deformation of the discharge portion 200 when pressure is applied to the container body 100 to discharge the contents. Specifically, when pressure is applied to the container body 100, at least one region of the deformation suppression groove 310 contracts or expands, changing the width of the deformation suppression groove 310. This prevents the deformation force caused by pressure applied to the container body 100 from being transmitted to the discharge portion 200 via the shoulder portion 300, suppressing 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 portion 300 where the deformation suppression groove 310 is formed may be in the range of 0.5 mm to 1.0 mm.

[0037] The deformation suppression groove 310 may be formed at a predetermined distance from the connection portion between the discharge portion 200 and / or the shoulder portion 300 and the container body 100. For example, the deformation suppression groove 310 may be annular and formed so as to wrap around the periphery of the lower end of the discharge portion 200 from the outside, while being spaced apart from the lower end of the discharge portion 200. In an embodiment, the deformation suppression groove 310 may be formed at a position 3 mm to 10 mm inward from the connection portion between the shoulder portion 300 and the container body 100.

[0038] To form the deformation suppression groove 310, the shoulder portion 300 may include a first bending fulcrum 320, a second bending fulcrum 330, and a third bending fulcrum 340. The first bending fulcrum 320, the second bending fulcrum 330, and the third bending fulcrum 340 are sequentially spaced apart from one another on the shoulder portion 300 from the periphery of the lower end portion of the discharge portion 200 outward, and the deformation suppression groove 310 can be formed by the shoulder portion 300 bending and deforming with a predetermined curvature around the first bending fulcrum 320 to the third bending fulcrum 340. For example, the deformation suppression groove 310 can be formed between the first bending fulcrum 320 and the third bending fulcrum 340 so that the second bending fulcrum 330 forms a valley (i.e., the point of greatest depth).

[0039] In the embodiment, a first inclined surface 311 and a second inclined surface 312 may be formed on the inside of the deformation suppression groove 310. For example, the first inclined surface 311 and the second inclined surface 312 may be arranged on both sides of the second bending fulcrum 330 and extend toward the first bending fulcrum 320 and the second bending fulcrum 330, respectively. As a result, the deformation suppression groove 310 may have a "V"-shaped cross section. When 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.

[0040] 3 to 5 are merely exemplary, and various shapes are applicable depending on the embodiment to which the present invention is applied. Depending on the embodiment, the content container 1000 may further include additional components such as a cap, a nozzle, etc. in addition to the container body 100, the discharge portion 200, and the shoulder portion 300.

[0041] Test example - deformation experiment by applying pressure to the container body As shown in Figure 6, a shoulder and discharge part including a deformation suppression groove (Figure 6(a)) according to the present invention and a shoulder and discharge part including a plurality of reinforcing ribs (Figure 6(b)) were manufactured. Here, the reinforcing ribs were used to support the discharge part from the outside in order to suppress deformation of the discharge part.

[0042] Next, a content container (Example 1) was manufactured using a shoulder portion and discharge portion according to the present invention, and a content container (Comparative Example 1) was manufactured using a shoulder portion and discharge portion including multiple reinforcing ribs, and then deformation tests were performed on both.

[0043] First, referring to Figure 7, when a discharge cap was attached to each discharge section of Example 1 and Comparative Example 1 and pressure was applied to the container body, in Example 1 (Figure 7(a)), in which a deformation suppression groove was formed, the width of the deformation suppression groove corresponding to the pressure position on the container body changed, and the shoulder portion moved significantly away from the cap, but in Comparative Example 1 (Figure 7(b)), in which a reinforcing rib was formed, it was confirmed that the change in the distance between the shoulder portion and the cap was small.

[0044] Next, referring to Figure 8 and Table 1 below, when pressure is applied to the container body in Example 1 and Comparative Example 1, it can be seen that the discharge portion in Example 1 (Figure 8(a)) maintains an approximately circular shape, whereas the discharge portion in Comparative Example 1 (Figure 8(b)) is deformed into an elliptical shape.

[0045] [Table 1]

[0046] From this, it can be seen that in the embodiment in which a deformation suppression groove is formed, the force (deformation force) caused by pressure being applied to the container body acts to deform the width of the deformation suppression groove, limiting its transmission to the discharge section, and accordingly effectively suppressing deformation of the shape of the discharge section.

[0047] Although the embodiments have been described above using limited examples and drawings, those skilled in the art will appreciate that various modifications and variations may be made from the above description. Furthermore, the embodiments may be combined with one another as needed. Therefore, other aspects, other embodiments, and equivalents to the claims are also within the scope of the claims.
