Description

[Technical Field]

[0001] The present invention relates to a container that allows fine adjustment of the amount of content discharged, and more particularly to a content container that allows fine adjustment of the degree of content discharged through an orifice. [Background technology]

[0002] In the fields of cosmetics, medicines, and daily necessities, there is a need for containers that allow the convenient and hygienic use of liquid or semi-liquid products. In particular, for low-viscosity formulations such as essences, serums, lotions, and emulsions, containers that allow the user to finely adjust the amount dispensed so that the user can use only the desired amount are required.

[0003] Existing low-viscosity dosage containers mainly use pump or squeeze mechanisms to dispense the product, but while these mechanisms are convenient, they have the drawback of making it difficult to accurately control the amount dispensed. Pump containers often have problems with inconsistent dispensed amounts and difficulty dispensing when only a small amount of product remains. Squeeze containers also have the drawback of making it difficult to accurately adjust the amount used, as the amount dispensed varies depending on the pressure applied.

[0004] Difficulty in adjusting the discharge rate can lead to excessive product waste, which can have negative environmental impacts and can lead to unnecessary financial burdens for consumers, especially when it comes to expensive cosmetics and pharmaceuticals.

[0005] [Patent Document 1] Republic of Korea Publication Patent No. 10-2018-0130146 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been devised to solve the above problems, and provides a content container that allows fine adjustment of the amount of content dispensed.

[0007] The technical problems of the present invention are not limited to the above-mentioned technical problems, 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] An embodiment of the present invention provides a content container, comprising: a tube including a tube neck having a discharge hole formed therein and configured to store content; a nozzle including a nozzle neck accommodated in the tube neck and a nozzle head extending from the nozzle neck and having a discharge hole formed therein through which the content can be discharged; and an orifice at least a portion of which is accommodated in the nozzle neck and configured to reduce a cross-sectional area of ​​a flow path through which the content can move, wherein the orifice forms an orifice flow path through which the content can move between the nozzle neck and an inner wall of the nozzle neck so that the content can move.

[0009] The orifice may be formed with an inwardly recessed channel to form an orifice channel.

[0010] The flow channel may extend parallel to the longitudinal direction of the nozzle neck.

[0011] A plurality of flow channel grooves may be provided, and the number of the plurality of flow channel grooves may be set to correspond to the viscosity of the contents.

[0012] The flow path formed to allow the contents to flow from the discharge hole to the ejection hole may be bent at least once by the orifice.

[0013] The orifice includes a nozzle insertion portion that is inserted into the nozzle, and a nozzle support portion that extends parallel to the nozzle insertion portion and sandwiches the nozzle neck therebetween, the nozzle neck includes a coupling protrusion that protrudes toward the nozzle support portion, and the nozzle support portion may be formed with a nozzle coupling groove that accommodates the coupling protrusion.

[0014] The orifice may include a nozzle support positioned between the nozzle and the tube neck, the nozzle support configured to prevent migration of contents between the nozzle and the tube neck.

[0015] The nozzle may further include a support extending radially from the nozzle head, the orifice supporting the support to prevent the nozzle from moving inwardly of the tube.

[0016] The orifice may include a tube-facing portion housed in the tube neck, and the tube-facing portion may have a through-hole formed therein configured to allow movement of the contents from the discharge hole toward the flow channel.

[0017] The through-hole may be adjacent to the flow channel.

[0018] The through-hole may be a groove that is connected to the flow channel and recessed inward.

[0019] The orifice may include a tube cover portion extending from the nozzle support portion and provided to cover the end of the tube neck, and the tube cover portion may be removably coupled to the tube neck.

[0020] The tube neck may include a coupling rib protruding toward the tube cover portion, and the tube cover portion may have a tube coupling groove formed therein to receive the coupling rib.

[0021] The orifice may have an opening formed toward the discharge hole and a recessed space recessed toward the discharge hole.

[0022] The nozzle and orifice may be combined to form a cap assembly that is removable from the tube neck. [Effects of the Invention]

[0023] According to the present invention, the content container includes an orifice located in the flow path through which the content moves, thereby reducing the amount of content passing through the flow path and easily adjusting the amount of content discharged. This allows fine adjustment of the amount of content discharged even for low-viscosity dosage forms, and is applicable regardless of dosage form, resulting in improved ease of use and product economy.

[0024] According to one embodiment of the present invention, the content container can simplify the assembly configuration with the tube by forming a cap assembly in which the nozzle and orifice are combined and can be removably combined with the tube, and the diameter of the tube can be made expandable.

[0025] According to one embodiment of the present invention, by forming a groove in the orifice, a flow path through which the contents can move can be easily formed between the orifice and the nozzle, and the degree of ejection of the contents can be adjusted by increasing or decreasing the number of grooves in the orifice depending on the viscosity of the contents.

[0026] According to an embodiment of the present invention, the flow path in which the contents are formed is formed so as to be bent by the orifice, so that the contents can be prevented from passing through the flow path.

[0027] According to one embodiment of the present invention, the orifice may provide a seal between the nozzle neck and the tube.

[0028] According to one embodiment of the present invention, a recessed space is formed in the orifice, which makes the orifice more easily deformable and easier to insert into the nozzle.

[0035] FIG. 1 is a perspective view of a content container 1 according to one embodiment of the present invention.

[0036] A content container 1 according to one embodiment of the present invention will be described with reference to FIG.

[0037] A content container 1 can be provided that is configured to contain and expel a content. In this case, the content may be, for example, a liquid. For example, the content may be liquid cosmetics or artificial tears.

[0038] The content container 1 may include a tube 400 configured to contain the content, a nozzle 200 configured to eject the content contained in the tube 400, and / or a cap 100 that covers the nozzle 200 to prevent the content from being ejected into the nozzle 200 when not needed. In this case, the cap 100 may be omitted as necessary. The nozzle 200 may be configured to have an ejection hole 201H (see FIG. 2) formed at its end so that the content is ejected through the ejection hole 201H. For reference, the nozzle 200 may be made of plastic or metal, and the cap 100 may be made of plastic or metal.

[0039] The tube 400 may have a shape that extends in one direction. The tube 400 may also be made of a deformable material. Furthermore, the tube 400 may be thin-walled so that it is easily deformed. A user may press the tube 400 to move the contents toward the nozzle 200. By deforming the tube 400, the volume of the space inside the tube 400 can be reduced, causing the contents contained in that space to move. The tube 400 may be made of plastic or metal.

[0040] It may be necessary to regulate the amount of content dispensed, particularly to prevent too much content from being dispensed when only a small amount of content needs to be used. This requires limiting the amount of content dispensed, as will be discussed in more detail below.

[0041] Fig. 2 is a cross-sectional view of the content container 1 shown in Fig. 1. Fig. 3 is a perspective view of the orifice 300 shown in Fig. 2. More specifically, Fig. 3(a) is a perspective view showing the orifice 300 according to a first embodiment. Fig. 3(b) is a perspective view showing the orifice 300 according to a second embodiment.

[0042] A content container 1 including an orifice 300 according to a first embodiment of the present invention will be described with reference to FIGS. 2 to 3(a).

[0043] First, the details of the configuration of the content container 1 will be described.

[0044] 2, the content container 1 may include a cap 100, a nozzle 200 configured to be covered by the cap 100, a tube 400 configured to contain the content, and / or an orifice 300 configured to adjust the amount of the content dispensed. In this case, the cap 100 can be omitted as necessary.

[0045] The cap 100 may be configured to cover the discharge hole 201H formed in the nozzle 200. The cap 100 may be configured to open and close the discharge hole 201H. While the cap 100 closes the discharge hole 201H, a portion of the cap 100 may extend inside the discharge hole 201H.

[0046] The nozzle 200 may include a nozzle neck 220, a nozzle head 210, and a support portion 230. In this case, the support portion 230 can be omitted as necessary.

[0047] The nozzle head 210 may have a discharge hole 201H formed at its end. The nozzle head 210 may be configured so that its cross-sectional area decreases as it progresses toward the discharge hole 201H. This allows the nozzle flow path P3P formed inside the nozzle head 210 to be configured so that its cross-sectional area decreases as it progresses toward the discharge hole 201H. The flow rate of the contents passing through the nozzle flow path P3P increases as it progresses toward the discharge hole 201H. This reduces the pressure of the contents on the discharge hole 201H side, and therefore the contents farther from the discharge hole 201H can be induced to move toward the discharge hole 201H due to the pressure difference. The user can easily expel the contents when they wish to use them.

[0048] The nozzle neck 220 may extend from the opposite side of the nozzle head 210 from the discharge hole 201H. In other words, the nozzle head 210 may be formed with a discharge hole 201H extending from the nozzle neck 220 and capable of discharging the contents. More specifically, the nozzle neck 220 may extend toward the tube 400. As shown in FIG. 2 , the nozzle neck 220 may extend downward. The nozzle neck 220 may be configured to be coupled to the tube 400. More specifically, the nozzle neck 220 may be configured to be coupled to the tube 400 by an orifice 300. The nozzle neck 220 may be configured to be housed in the tube 400. More specifically, the nozzle neck 220 may be configured to be housed in a tube neck 420, which will be described later. A portion of the orifice 300 may be located between the nozzle neck 220 and the tube neck 420, thereby coupling the nozzle neck 220 and the tube 400. The nozzle neck 220 may be housed in a space formed by the orifice 300 relative to the orifice 300. Additionally, the nozzle neck 220 may include a coupling protrusion 221 that protrudes outward. Details of the coupling protrusion 221 will be described in the section describing the related configuration.

[0049] The support portion 230 may extend in the radial direction from the nozzle head 210. As shown in FIG. 2, the support portion 230 may extend in the left-right direction and extend circumferentially from the lower side of the nozzle head 210. The support portion 230 may extend in the radial direction beyond the outer diameter position of the space formed in the orifice 300. In this way, the support portion 230 is supported by the orifice 300, and it is possible to prevent the nozzle 200 from moving inside the tube 400.

[0050] The tube 400 configured to store the contents may include a soft tube body 410 configured to accommodate the contents, and a tube neck 420 coupled to the opening of the tube body 410. In this case, the tube body 410 can be omitted as necessary.

[0051] The tube body 410 is thinner than the tube neck 420 and can be easily deformed. The tube body 410 may be configured so that its shape changes when pressed, causing the contents located inside to move toward the tube neck 420. An opening is formed at one end of the tube body 410, and the opening of the tube body 410 can be used as a passage for filling the contents inside the tube body 410.

[0052] The tube neck 420 is coupled to an opening formed at one end of the tube body 410 to adjust the flow of the contents. The tube neck 420 may have a discharge hole 421H formed therein, through which the contents pass. More specifically, the tube neck 420 may include an inlet 421 configured to cover the opening of the tube body 410. With reference to FIG. 2 , the inlet 421 may extend in the left-right direction. The discharge hole 421H is formed in the inlet 421, and the contents discharged from the tube body 410 can move through the discharge hole 421H. In this case, the discharge hole 421H has a smaller cross-sectional area than the opening of the tube body 410, thereby reducing the amount of contents discharged. This reduction in the amount of contents discharged makes it easier to adjust the amount of contents discharged. The inlet 421 may have a recessed portion on the side facing the orifice 300 that is recessed away from the orifice 300 to match the shape of the orifice 300. The inlet portion 421 may form a tube flow path P1 between itself and the orifice 300. The tube flow path P1 can be defined as a flow path P from the discharge hole 421H to the orifice flow path P2, which will be described later. The shape of the inlet portion 421 corresponding to the orifice 300 maintains a constant cross-sectional area of ​​at least a portion of the tube flow path P1, preventing the flow of the contents from being obstructed. Furthermore, the tube neck 420 may include a portion extending in the longitudinal direction of the tube 400. The tube neck 420 may include a connecting rib 422 extending radially outward. Details of the connecting rib 422 will be described in the section describing the orifice 300 connected to the connecting rib 422.

[0053] An orifice 300 configured to limit the amount of content discharged to a predetermined value or less may be provided. The orifice 300 may be provided so that at least a portion thereof is located between the nozzle 200 and the tube neck 420. More specifically, the orifice 300 may be configured so that at least a portion thereof is contained within the nozzle neck 220 to reduce the cross-sectional area of ​​the flow path P through which the content can move. If the orifice 300 is not provided, the flow path P formed between the discharge hole 421H and the discharge hole 201H is defined only by the nozzle 200. The orifice 300 may be contained within the nozzle 200 to form a flow path P with a smaller cross-sectional area than the flow path P defined only by the nozzle 200. As the area of ​​the flow path P becomes smaller, the amount of content passing through the flow path P decreases. Therefore, the amount or speed of the content discharged from the discharge hole 201H of the nozzle 200 can be reduced. More specifically, the orifice 300 can form an orifice flow path P2 between itself and the inner wall of the nozzle neck 220, through which the contents can move. However, if necessary, the nozzle neck 220 can be accommodated in the tube neck 420, rather than the nozzle neck 220 being accommodated in the tube neck 420, and the orifice 300 can be accommodated inside the tube neck 420, thereby forming the orifice flow path P2 between the inner wall of the tube neck 420 and the orifice 300. For reference, the orifice 300 may be made of rubber. This improves the sealing effect between the orifice 300 and the adjacent components and also makes it more easily deformable.

[0054] As shown in Fig. 3(a), an inwardly recessed flow channel groove 311H may be formed in the orifice 300 to form an orifice flow channel P2. As shown in Fig. 2, the orifice flow channel P2 can be defined by the inner wall of the nozzle neck 220 and the flow channel groove 311H. If necessary, the orifice flow channel P2 may be formed between the outer surface of the orifice 300 and the inner wall of the nozzle neck 220 without the flow channel groove 311H. However, by forming the flow channel groove 311H, when forming the orifice flow channel P2, the discharge rate of the content can be easily adjusted by adjusting the area and number of the flow channel groove 311H.

[0055] The flow channel 311H may extend parallel to the longitudinal direction of the nozzle neck 220. By making the longitudinal direction of the nozzle neck 220 and the flow channel groove 311H parallel, the extension direction of the orifice flow channel P2 can be parallel to the extension direction of the nozzle neck 220. The extension direction of the nozzle neck 220 is parallel to the extension direction of the nozzle flow channel P3P, and therefore the orifice flow channel P2 can be parallel to the nozzle flow channel P3P. This allows the contents that have escaped from the orifice flow channel P2 to easily move to the nozzle flow channel P3P.

[0056] Furthermore, if necessary, the orifice flow path P2 may have a cross-sectional area that varies along the longitudinal direction. If the cross-sectional area of ​​the orifice flow path P2 increases as it advances toward the discharge hole 201H, the discharge speed of the content can be further slowed.

[0057] 3(a), the orifice 300 may have a through-hole 321H formed below the flow channel 311H. The contents may be configured to move from the tube flow channel P1 to the orifice flow channel P2 through the through-hole 321H. In other words, the through-hole 321H may be configured to allow the contents to move from the discharge hole 421H toward the flow channel 311H.

[0058] The through-hole 321H may be adjacent to the flow channel 311H, which prevents the flow channel P formed from the through-hole 321H to the flow channel 311H from bending, and reduces energy loss due to friction as the contents that have flowed into the through-hole 321H move to the flow channel 311H.

[0059] The flow path P, which allows the contents to flow from the discharge hole 421H to the discharge hole 201H, may be bent at least once by the orifice 300. As shown in FIG. 2, the flow path P may include a tube flow path P1, an orifice flow path P2, and / or a nozzle flow path P3P. The contents traveling from the discharge hole 421H to the tube flow path P1 may be bent as they move through the orifice flow path P2. The orifice flow path P2, which is formed between the inner wall of the nozzle neck 220 and the orifice, extends upward and then bends to the right again, allowing the contents to be bent as they move along the orifice flow path P2. The contents exiting the orifice flow path P2 may be bent upward again as they move toward the nozzle flow path P3P. As shown in FIG. 2, the flow path P, which is configured to allow the contents to move, may be bent four times, defined as being bent as it moves from the discharge hole 421H to the tube flow path P1. If the flow path P is bent, there is a risk of energy loss in the flow of the contents at the bent portion, which can further delay the discharge of the contents.

[0060] The orifice 300 will now be described in detail.

[0061] The orifice 300 may include a nozzle insertion portion 310 inserted into the nozzle 200, a tube facing portion 320 extending from the nozzle insertion portion 310 in a direction different from the extending direction of the nozzle insertion portion 310, a nozzle support portion 330 extending from the tube facing portion 320 in a direction different from the extending direction of the tube facing portion 320, a tube cover portion 340 extending in a direction different from the extending direction of the nozzle support portion 330 and / or a flange portion 350 extending in a direction different from the extending direction of the tube cover portion 340. In this case, the nozzle support portion 330, the tube cover portion 340 and the flange portion 350 can be omitted as necessary.

[0062] The nozzle insertion portion 310 may be inserted into the nozzle neck 220. The nozzle insertion portion 310 may be substantially annular and extend in the up-down direction. The nozzle insertion portion 310 may face the inner surface of the nozzle neck 220. The flow path groove 311H described above may be formed in the nozzle insertion portion 310. The portion of the nozzle insertion portion 310 where the flow path groove 311H is not formed is in close contact with the inner surface of the nozzle neck 220, thereby preventing the contents from moving between the nozzle neck 220 and the nozzle insertion portion 310.

[0063] The tube facing portion 320 may be located on the side of the nozzle neck 220 facing the discharge hole 421H. In other words, the tube facing portion 320 may be located below the nozzle insertion portion 310. The tube facing portion 320 may be housed in the tube neck 420. The tube facing portion 320 may face the inlet portion 421 of the tube neck 420. The tube facing portion 320 may include a protrusion 322 that connects the nozzle insertion portions 310 and is convex toward the discharge hole 421H. A portion of the tube flow path P1 formed between the protrusion 322 and the inlet portion 421 of the tube neck 420 is formed to be inclined toward the through hole 321H by the protrusion 322, thereby reducing the bending angle of the flow path P located between the tube flow path P1 and the through hole 321H. The tube flow path P1 formed between the protrusion 322 and the inlet portion 421 may be configured to be inclined toward the discharge hole 201H with respect to the direction from the discharge hole 421H toward the through hole 321H. The tube facing portion 320 may further include a portion that extends outward from the protrusion 322 and supports the lower end of the nozzle neck 220. The above-mentioned through hole 321H may be formed in the tube facing portion 320.

[0064] In this case, the orifice 300 may have an opening facing the discharge hole 201H and a recessed space 310S recessed toward the discharge hole 421H. More specifically, an opening may be formed on the upper side of the recessed space 310S. The recessed space 310S may be formed by the nozzle insertion portion 310 and the protrusion 322. The recessed space 310S makes it easier for the nozzle insertion portion 310 to deform inward. Because the nozzle insertion portion 310 is inserted into the nozzle neck 220 and is positioned so as to contact the inner surface of the nozzle neck 220, it may be difficult to insert the nozzle insertion portion 310 into the nozzle neck 220. The formation of the recessed space 310S makes it easier for the nozzle insertion portion 310 to be inserted into the nozzle neck 220.

[0065] The nozzle support portion 330 may extend upward and downward from the outside of the tube-facing portion 320. The nozzle support portion 330 may be located between the nozzle 200 and the tube neck 420. The nozzle support portion 330 may be configured to prevent the transfer of contents between the nozzle 200 and the tube neck 420. More specifically, the nozzle insertion portion 310, the tube-facing portion 320, and the nozzle support portion 330 contact and seal the nozzle neck 220 between the nozzle neck 220 and the orifice 300, thereby preventing the contents from leaking between the nozzle neck 220 and the orifice 300.

[0066] Furthermore, the nozzle support 330 may extend so as to slope outward as it extends upward. The nozzle support 330 may contact the inner wall of the tube neck 420 and be coupled to the tube neck 420. The inclination of the nozzle support 330 allows the nozzle support 330 to be coupled to the tube neck 420 by an interference fit. In particular, since the upper end of the nozzle support 330 is positioned at a height corresponding to the opening of the recessed space 310S, the nozzle support 330 can deform inward while being inserted into the tube neck 420, making it easier to insert the nozzle support 330. After the nozzle support 330 is inserted into the tube neck 420, a force is generated that causes the orifice 300 to return to its original state, bringing the nozzle support 330 and the tube neck 420 into close contact, thereby strengthening the coupling between the orifice 300 and the tube neck 420.

[0067] The nozzle support part 330 may include a support protrusion 332 that protrudes below the tube facing part 320 and is supported by the tube neck 420. This allows the support protrusion 332 to maintain a gap between the tube facing part 320 and the inlet part 421 of the tube neck 420, thereby forming a tube flow path P1 through which the contents can pass. Furthermore, the support protrusion 332 seals the gap with the tube neck 420, preventing the contents from leaking out between the nozzle support part 330 and the tube neck 420.

[0068] The nozzle neck 220 may include a coupling protrusion 221 that protrudes toward the nozzle support portion 330. The coupling protrusion 221 may protrude radially outward from the nozzle neck 220. The nozzle support portion 330 may have a nozzle coupling groove 331H formed therein to receive the coupling protrusion 221. The nozzle coupling groove 331H may be formed to correspond to the coupling protrusion 221. The coupling protrusion 221 is received in the nozzle coupling groove 331H, allowing the orifice 300 to be coupled to the nozzle 200.

[0069] The tube cover portion 340 may extend from the nozzle support portion 330 and may be provided to cover the end of the tube neck 420. The tube cover portion 340 may include a portion that is bent and extends radially outward from the nozzle support portion 330 and a portion that is bent and extends again toward the tube 400. A portion of the tube cover portion 340 and the nozzle support portion 330 may face each other. This allows the tube neck 420 to be inserted between the tube cover portion 340 and the nozzle support portion 330.

[0070] The tube cover portion 340 may be detachably coupled to the tube neck 420. The tube neck 420 may include a coupling rib 422 protruding toward the tube cover portion 340. The tube cover portion 340 may be formed with a tube coupling groove 341H into which the coupling rib 422 is received. The tube coupling groove 341H may have a shape corresponding to the coupling rib 422. The coupling rib 422 may include a portion that slopes outward from the top to the bottom. This makes it easier for the coupling rib 422 to be inserted into the tube coupling groove 341H. The coupling rib 422 and the tube coupling groove 341H allow the orifice 300 to be detachably coupled to the tube neck 420. In other words, the nozzle 200 and the orifice 300 may be coupled to form a cap assembly CA that is detachable from the tube neck 420. In other words, by forming a cap assembly CA in which the cap 100, the nozzle 200, and the orifice 300 are modularized, the assembly configuration with the tube 400 can be simplified and the diameter of the tube 400 can be made expandable.

[0071] The tube cover part 340 may include a cap coupling part 341 that protrudes outward. The cap coupling part 341 may be a part that is coupled to the cap 100. The cap 100 may have a corresponding part that is screwed onto the cap coupling part 341. This allows the cap 100 to be coupled to or detached from the orifice 300 by rotation.

[0072] The flange portion 350 may protrude outward from the tube cover portion 340. The flange portion 350 contacts the tube 400 and can ultimately seal any contents that may leak between the tube 400 and the orifice 300. Furthermore, the flange portion 350 may support the cap 100 and limit the radius of rotation of the cap 100 when coupled with the orifice 300.

[0073] Below, other embodiments different from the above-described embodiments will be described. Details common to the above-described embodiments will be omitted as much as possible, and the other embodiments different from the above-described embodiments will be described with emphasis on the differences. In other words, it goes without saying that if details not described in the other embodiments are necessary, they can be supplemented by the details of the above-described embodiments.

[0074] FIG. 3(b) shows an orifice 300 according to a second embodiment of the present invention.

[0075] An orifice 300 according to a second embodiment of the present invention will be described with reference to FIG. 3(b).

[0076] The second embodiment differs from the first embodiment in that the orifice 300 has a plurality of flow channel grooves 311H-1 formed therein.

[0077] A plurality of flow grooves 311H-1 may be provided. The number of flow grooves 311H-1 may be determined according to the viscosity of the contents. That is, as the viscosity of the contents increases, the number of flow grooves 311H-1 increases accordingly. As the viscosity of the contents decreases, the number of flow grooves 311H-1 decreases accordingly. As a result, regardless of differences in the viscosity of the contents, the amount or speed of the contents discharged through the discharge hole 201H can be set to a constant, desired amount or speed.

[0078] Furthermore, the plurality of flow channels 311H-1 may be formed at a maximum distance or angle from each other. As shown in Figure 3(b), when two flow channels 311H-1 are formed, they may be positioned at an angle of 180° from each other. This makes it possible to prevent interference between the flows of the contents flowing into each flow channel 311H-1.

[0079] Additionally, a plurality of through holes 321H may also be provided corresponding to the flow channel 311H-1.

[0080] Figure 4 is a cross-sectional view and an enlarged view of a content container 1 and an orifice 300 according to another embodiment of the present invention. More specifically, Figure 4(a) is a cross-sectional view of a content container 1 and an orifice 300 according to a third embodiment. Figure 4(b) is a cross-sectional view of a content container 1 and an orifice 300 according to a fourth embodiment.

[0081] The third and fourth embodiments are different from the first embodiment in that the flow channel grooves 311H-2 and 311H-3 are formed so as to form a plurality of flow channels P.

[0082] The flow channel grooves 311H-2 and 311H-3 may be configured to form multiple flow channels P. As the number of flow channels P formed by the flow channel grooves 311H-2 and 311H-3 increases, the overall cross-sectional area of ​​the flow channel grooves 311H-2 and 311H-3 can increase. The number of flow channels P formed by the flow channel grooves 311H-2 and 311H-3 may be set to correspond to the viscosity of the contents. That is, as the viscosity of the contents increases, the number of flow channels P formed by the flow channel grooves 311H-2 and 311H-3 increases accordingly. As the viscosity of the contents decreases, the number of flow channels P formed by the flow channel grooves 311H-2 and 311H-3 decreases accordingly. As a result, regardless of differences in the viscosity of the contents, the amount or speed of the contents discharged through the discharge hole 201H can be set to a desired amount or speed.

[0083] In this case, the third embodiment shown in FIG. 4(a) shows a case where there is a single flow channel 311H-2, and the fourth embodiment shown in FIG. 4(b) shows a case where two flow channel 311H-3 like the third embodiment are formed like the second embodiment.

[0084] Figure 5 is a cross-sectional view and an enlarged view of a content container 1 and an orifice 300 according to yet another embodiment of the present invention. More specifically, Figure 5(a) is a cross-sectional view of a content container 1 and an orifice 300 according to a fifth embodiment. Figure 5(b) is a cross-sectional view of a content container 1 and an orifice 300 according to a sixth embodiment.

[0085] The fifth and sixth embodiments differ from the first embodiment in that the flow path grooves 311H-4 and 311H-5 have different shapes and that a flow path recess 312H-5 is formed by changing the shape of the end of the orifice flow path P2. In particular, the fifth and sixth embodiments differ from the first embodiment in that the flow path grooves 311H-4 and 311H-5 form a single flow path P, but only the shapes of the flow path grooves 311H-4 and 311H-5 are different.

[0086] The cross section of the flow channel grooves 311H-4 and 311H-5 may be rectangular. If necessary, the cross section of the flow channel grooves 311H-4 and 311H-5 may have a specific shape. Furthermore, the area of ​​the flow channel grooves 311H-4 and 311H-5 may be changed depending on the viscosity of the content to determine the discharge amount of the content.

[0087] Furthermore, a flow path recess 312H-5 recessed downward may be formed at the upper end of the nozzle insertion portion 310 of the orifice 300. A flow path P having a larger cross-sectional area than the orifice flow path P2 in the first embodiment may be formed in the portion of the orifice flow path P2 on the side where the flow path recess 312H-5 is formed. This reduces energy loss in the contents flowing along the flow path recess 312H-5.

[0088] In this case, the fifth embodiment shown in FIG. 5(a) shows a case where there is a single flow channel 311H-4, and the sixth embodiment shown in FIG. 5(b) shows a case where two flow channel 311H-5 like the fifth embodiment are formed like the second embodiment.

[0089] Fig. 6 is a cross-sectional view and an enlarged view of a content container 1 and an orifice 300 according to yet another embodiment of the present invention. More specifically, Fig. 6 is a cross-sectional view of a content container 1 and an orifice 300-6 according to a seventh embodiment of the present invention.

[0090] An orifice 300-6 according to a seventh embodiment of the present invention will be described with reference to FIG.

[0091] The seventh embodiment differs from the first embodiment in that the through-hole 321H-6 formed in the orifice 300-6 is a groove, and that the orifice 300-6 has a protrusion 360-6.

[0092] The through-hole 321H-6 may be a groove connected to the flow channel 311H-6 and recessed inward. Here, the term "hole" should be understood to include the meaning of "groove." By connecting the through-hole 321H-6 and the flow channel 311H-6, energy loss during the flow of the contents moving from the through-hole 321H-6 to the flow channel 311H-6 is minimized.

[0093] In this case, the through-hole 321H-6 may be formed in the tube facing portion 320-6 extending outward from the lower side of the nozzle insertion portion 310-6.

[0094] Orifice 300-6 may include a protrusion 360-6 that protrudes outward from nozzle insert 310-6. Protrusion 360-6 can provide a seal between the inner surface of nozzle neck 220 and nozzle insert 310-6. Multiple protrusions 360-6 may be provided and arranged one above the other.

[0095] The drawings and specification disclose the best mode for carrying out the present invention. Although specific terms are used herein, these terms are merely used for the purpose of clearly describing the present invention and are not intended to limit the meaning or the scope of the present invention as set forth in the claims. Therefore, a person skilled in the art will understand that various modifications and equivalent alternative embodiments may be employed. Therefore, the true technical scope of protection of the present invention is defined by the appended claims. [Explanation of symbols]
