Description

【Technical Field】 【0001】 The present invention relates to a container for contents, and more particularly, to a container for contents that can effectively suppress deformation of a discharge portion. 【Background Art】 【0002】 As shown in FIG. 1, a conventional tube container may include a flexible container body 11 for storing contents, a discharge portion 12 having an open upper end for discharging the contents of the container body 11, and a shoulder portion 13 extending from the lower end of the discharge portion 12 for connecting the container body 11 and the discharge portion 12. On the other hand, although not shown in FIG. 1, a cap or nozzle having a discharge hole may be further coupled to the discharge portion 12. 【0003】 Such a tube container is configured such that when a user presses the outer surface of the container body 11, the inside of the container body 11 rises and is discharged to the outside through the discharge portion 12 or a cap connected to the discharge portion 12. 【0004】 By the way, as shown in FIG. 2, in a conventional tube container, when the container body 11 is pressurized, the force due to the pressurization is transmitted to the discharge portion 12 through the shoulder portion 13, and the shape of the discharge portion 12 is deformed from circular to elliptical. As a result, there are problems such as the contents leaking from between the discharge portion 12 and a cap or the like connected thereto. 【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】 【Problems to be Solved by the Invention】 【0006】 The present invention has been made to solve the above problems, and an object thereof is to provide a container for contents that can effectively suppress deformation of a discharge portion. 【0007】 The technical problems of the present invention are not limited to those 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 container for contents according to an embodiment of the present invention is provided. The contents container has a storage space formed inside for storing the contents, and the container body is pressurized by external force, The upper end is open, and the container body is pressurized to discharge the contents, A shoulder portion extends from the periphery of the lower end of the discharge section and connects the discharge section and the container body, Includes, A deformation-reducing groove is provided in at least one area of ​​the shoulder portion to suppress deformation of the discharge portion when the container body is pressurized. ru . The shoulder portion has a first bending point, a second bending point, and a third bending point arranged sequentially apart from the lower end of the discharge section, and is deformed by bending around the first to third bending points. The deformation-restricting groove is formed between the first and third bending supports such that the second bending support forms a valley. The deformation-suppressing groove has a first inclined surface extending from the second bending support point toward the first bending support point, and a second inclined surface extending from the second bending support point toward the third bending support point. In an unpressurized state relative to the container body, the angle between the first inclined surface and the second inclined surface is between 60 and 120 degrees. When the container body is pressed, the width of the deformation-suppressing groove changes, preventing the deformation force caused by the press from being transmitted to the discharge section via the shoulder, thereby suppressing deformation of the discharge section. [Effects of the Invention] 【0009】 According to the present invention, when pressurizing the container body, the transmission of deformation force is restricted through deformation-suppressing grooves formed on the shoulder portion, thereby effectively suppressing changes in the shape of the discharge portion.

The container body 100 may have the form of a tube container with an open upper end and a sealed lower end, but is not limited to this, and may have various container structures such as a soft bottle or tottle whose volume decreases under pressure. 【0028】 In the embodiment, the container body 100 may be made of a flexible material in part. When a user applies external force and pressurizes the outer surface of the container body 100, the container body 100 deforms (i.e., is compressed), and the contents can be discharged to the outside through the discharge section 200. 【0029】 In this case, the contents may include, for example, liquid or gel-type cosmetics, pharmaceuticals, quasi-drugs, etc. For example, the contents may include lotions, milk lotions, moisture lotions, moisturizing lotions, nourishing lotions, skin lotions, skin softeners, skin toners, astringents, massage creams, nourishing creams, moisturizing creams, whitening essences, tone-up creams, sunscreens (UV blockers), sunscreen creams (sun creams), sunscreen milks (sun milks), BB creams, makeup bases (bases), foundations, CC creams, concealers, blushes, shading products, eyeshadows, eyebrow products, eye creams, etc., but are not limited to these, and may include various types or components of substances that can be contained in the container body 100 and discharged to the outside by pressurizing the container body 100. 【0030】 The discharge section 200 is formed on the upper side of the container body 100 so as to communicate with the container body 100, and the contents can be discharged to the outside through the open upper end. 【0031】 In the embodiment, the discharge section 200 may be connected to a cap or nozzle with a discharge hole, a pump, or the like. Therefore, at least one connecting part may be formed on the outer circumferential surface of the discharge section 200. The connecting part may be, for example, a screw thread, a connecting projection, or a connecting groove, but is not limited thereto, and various connecting structures can be applied. 【0032】 The shoulder portion 300 extends downward outward from around the lower end of the discharge portion 200 at a predetermined incline, 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 the 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 heat bonding, ultrasonic bonding, bonding with adhesive, or double injection molding. 【0035】 In the embodiment, at least a portion of the container body 100, the discharge section 200, and the shoulder section 300 may be integrally formed with each other by injection molding or the like. For example, the discharge section 200 and the shoulder section 300 may be integrally formed by injection molding or the like, and then bonded to the upper end of the container body 100. 【0036】 A deformation-suppressing groove 310 may be recessed inward in at least one area of ​​the shoulder portion 300. The deformation-suppressing groove 310 can suppress deformation of the shape of the discharge portion 200 when the container body 100 is pressurized to discharge the contents. Specifically, when the container body 100 is pressurized, at least one area of ​​the deformation-suppressing groove 310 contracts or expands, changing the width of the deformation-suppressing groove 310. This prevents the deformation force due to the pressurization of the container body 100 from being transmitted to the discharge portion 200 via the shoulder portion 300, thereby suppressing deformation of the shape of the discharge portion 200. In the embodiment, the maximum depth of the deformation-suppressing groove 310 may be in the range of 0.8 mm to 2 mm, and the thickness of the area of ​​the shoulder portion 300 in which the deformation-suppressing groove 310 is formed may be in the range of 0.5 mm to 1.0 mm. 【0037】 The deformation-suppressing 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-suppressing groove 310 may be annular in shape and formed to surround the lower end of the discharge portion 200 from the outside, away from the lower end of the discharge portion 200. In the embodiment, the deformation-suppressing 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】 In forming the deformation-suppressing groove 310, the shoulder portion 300 may include a first bending support point 320, a second bending support point 330, and a third bending support point 340. The first bending support point 320, the second bending support point 330, and the third bending support point 340 are arranged sequentially spaced apart on the shoulder portion 300, extending outward from around the lower end of the discharge portion 200, and the deformation-suppressing groove 310 can be formed by the shoulder portion 300 bending deformed with a predetermined curvature around the first bending support point 320 to the third bending support point 340. For example, the deformation-suppressing groove 310 can be formed between the first bending support point 320 and the third bending support point 340 such that the second bending support point 330 forms a valley (i.e., the point of maximum depth). 【0039】 In the embodiment, a first inclined surface 311 and a second inclined surface 312 may be formed inside the deformation-suppressing 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 support point 330 and extend toward the first bending support point 320 and the second bending support point 330, respectively. As a result, the deformation-suppressing groove 310 may have a "V" shaped cross-section. In an unpressurized state relative to the container body 100, the angle between the first inclined surface 311 and the second inclined surface 312 may be in the range of 60 to 120 degrees. 【0040】 The shapes of the contents container 1000 shown in Figures 3 to 5 are illustrative, and various shapes can be applied depending on the embodiment to which the present invention is applied. In addition, depending on the embodiment, the contents container 1000 may further include additional components such as a cap and a nozzle, in addition to the container body 100, the discharge section 200 and the shoulder section 300. 【0041】 Test Example - Deformation experiment due to pressurization of the container body As shown in Figure 6, a shoulder portion and discharge portion including deformation-suppressing grooves according to the present invention (Figure 6(a)) and a shoulder portion and discharge portion including a plurality of reinforcing ribs (Figure 6(b)) were manufactured. Here, the reinforcing ribs were applied to support the discharge portion from the outside in order to suppress deformation of the discharge portion. 【0042】 Next, a content container (Example 1) was manufactured using the shoulder portion and discharge portion according to the present invention, and a content container (Comparative Example 1) was manufactured using the shoulder portion and discharge portion including multiple reinforcing ribs. After that, deformation tests were performed on both. 【0043】 First, referring to Figure 7, when discharge caps were attached to the discharge sections of Example 1 and Comparative Example 1, respectively, and pressure was applied to the container body, in Example 1 (Figure 7(a)), which had deformation-suppressing grooves, the width of the deformation-suppressing grooves corresponding to the pressure applied to the container body changed, causing the shoulder portion to move significantly away from the cap. However, in Comparative Example 1 (Figure 7(b)), which had reinforcing ribs, 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 pressurization was applied to the container body in Example 1 and Comparative Example 1, it can be seen that in Example 1 (Figure 8(a)), the discharge section maintained a nearly circular shape, while in Comparative Example 1 (Figure 8(b)), the discharge section deformed into an elliptical shape. 【0045】 [Table 1] 【0046】 From this, it can be seen that in the embodiment in which deformation-suppressing grooves are formed, the force (deformation force) due to the pressure applied to the container body acts to deform the width of the deformation-suppressing grooves, limiting the transmission to the discharge section, and thereby effectively suppressing the deformation of the shape of the discharge section. 【0047】 Although the embodiments have been described above with limited examples and drawings, any person with ordinary skill in the art can make various modifications and variations from the above description. Furthermore, each embodiment can be combined with others as needed. Therefore, other embodiments, other examples, and equivalents to the claims also fall within the scope of the claims.
