Description

Technology Field

[0001] The present invention relates to a container capable of finely controlling the amount of contents discharged, and more specifically, to a container capable of finely controlling the degree of discharge of contents through an orifice. Background Technology

[0002] In fields such as cosmetics, pharmaceuticals, and household goods, there is a need to provide containers that allow for the convenient and hygienic use of products in a liquid or semi-liquid state. In particular, for low-viscosity formulations such as essences, serums, toners, and lotions, containers capable of finely adjusting the dispensing amount are required so that users can use the desired amount.

[0003] Conventional low-viscosity formulation containers primarily dispense products using pump or squeeze mechanisms; while these methods are easy to use, they have the disadvantage of making it difficult to accurately control the dispensing volume. Pump containers often dispense inconsistent amounts or fail to dispense properly when the product is low. Additionally, squeeze mechanisms have the drawback that the dispensing volume varies depending on the applied pressure, making it difficult to precisely control the amount used.

[0004] When it is difficult to control the dispensing volume, excessive discharge leads to product waste, which can have a negative impact on the environment and result in an unnecessary economic burden for consumers. This is an even more critical issue, particularly for high-priced cosmetics or pharmaceuticals. Prior art literature

[0008] According to an embodiment of the present invention, a contents container is provided. The contents container comprises a tube configured to store contents, including a tube neck having a discharge hole formed therein; a nozzle including a nozzle neck received in the tube neck and a nozzle head extending from the nozzle neck having a discharge hole formed therein capable of discharging contents; and an orifice configured to reduce the cross-sectional area of ​​a flow path through which contents can move, at least a portion of which is received in the nozzle neck. The orifice forms an orifice flow path through which contents can move between itself and the inner wall of the nozzle neck.

[0009] The orifice may have an inwardly concave groove formed to form an orifice flow path.

[0010] The Euro groove can be extended parallel to the longitudinal direction of the nozzle neck.

[0011] Euro grooves are provided in multiple numbers, and the number of Euro grooves can be provided to correspond to the viscosity of the contents.

[0012] A flow path formed to allow contents to flow from a discharge hole to a discharge hole may be formed to be bent at least once by an orifice.

[0013] The orifice includes a nozzle insertion portion inserted into a nozzle and a nozzle support portion extending parallel to the nozzle insertion portion and the nozzle neck, the nozzle neck includes a coupling projection protruding toward the nozzle support portion, and the nozzle support portion may have a nozzle coupling groove formed therein that receives the coupling projection.

[0014] The orifice includes a nozzle support located between the nozzle and the tube neck, and the nozzle support may be configured to prevent the movement of contents between the nozzle and the tube neck.

[0015] The nozzle further includes a support extending radially from the nozzle head, and the orifice can support the support to prevent the nozzle from moving into the tube.

[0016] The orifice includes a tube-opposite portion that is received in the tube neck, and the tube-opposite portion may have a through hole formed therein configured to allow the movement of contents from the discharge hole toward the flow path groove.

[0017] The through hole can be adjacent to the Euro groove.

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

[0036] Referring to FIG. 1, a contents container (1) according to one embodiment of the present invention will be described.

[0037] A content container (1) configured to receive and dispense contents may be provided. In this case, the contents may be, for example, liquid. For example, the contents may be liquid cosmetics or artificial tears.

[0038] The contents container (1) may include a tube (400) configured to receive contents, a nozzle (200) configured to discharge contents received in the tube (400), and / or a cap (100) that covers the nozzle (200) to prevent contents from being discharged through the nozzle (200) when not necessary. In this case, the cap (100) may be omitted as needed. The nozzle (200) may be configured to have a discharge hole (201H) (see FIG. 2) formed at its end so that contents are discharged through the discharge 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. Furthermore, the tube (400) may have a deformable material. Furthermore, the tube (400) may be thin to facilitate deformation. The user may pressurize the tube (400) to move the contents toward the nozzle (200). By deforming the tube (400), the volume of the inner space of the tube (400) can be reduced, thereby inducing movement of the contents contained in that space. The tube (400) may have a plastic or metal material.

[0040] It may be necessary to control the amount of contents dispensed. In particular, when only a small amount of contents is to be used, it is necessary to prevent a large amount from being dispensed. To this end, it is necessary to limit the amount of contents dispensed. This is explained in detail below.

[0041] FIG. 2 is a cross-sectional view of the contents 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 an orifice (300) according to a first embodiment. FIG. 3(b) is a perspective view showing an orifice (300) according to a second embodiment.

[0042] Referring to FIGS. 2 to 3(a), a contents container (1) including an orifice (300) according to a first embodiment of the present invention is described.

[0043] First, the composition of the contents container (1) will be explained in detail.

[0044] As illustrated in FIG. 2, the contents container (1) may include a cap (100), a nozzle (200) configured to be covered by the cap (100), a tube (400) configured to receive contents, and / or an orifice (300) configured to control the discharge amount of contents. In this case, the cap (100) may be omitted as needed.

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

[0046] The nozzle (200) may include a nozzle neck (220), a nozzle head (210), and a support member (230). At this time, the support member (230) may be omitted as needed.

[0047] A nozzle head (210) may have a discharge hole (201H) formed at its end. The nozzle head (210) may be configured such that its cross-sectional area decreases as it approaches the discharge hole (201H). Accordingly, the nozzle flow path (P3)(P) formed inside the nozzle head (210) may be formed such that its cross-sectional area decreases as it approaches the discharge hole (201H). The flow velocity of the contents passing through the nozzle flow path (P3)(P) may increase as it approaches the discharge hole (201H), and accordingly, the pressure of the contents on the discharge hole (201H) side may decrease; thus, the contents on the side far from the discharge hole (201H) may be induced to move toward the discharge hole (201H) due to the pressure difference. When a user intends to use the contents, the discharge of the contents can be facilitated.

[0048] The nozzle neck (220) may extend from the opposite side of the discharge hole (201H) of the nozzle head (210). In other words, the nozzle head (210) may extend from the nozzle neck (220) and form a discharge hole (201H) through which contents can be discharged. 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 received in the tube (400). More specifically, the nozzle neck (220) may be configured to be received in the tube neck (420) described later. A portion of the orifice (300) may be positioned between the nozzle neck (220) and the tube neck (420) to connect the nozzle neck (220) and the tube (400). In relation to the orifice (300), the nozzle neck (220) may be received in the space formed in the orifice (300). Additionally, the nozzle neck (220) may include a coupling projection (221) that protrudes outward. The coupling projection (221) will be described in more detail in the description of the related configuration.

[0049] The support member (230) may extend radially from the nozzle head (210). As shown in FIG. 2, the support member (230) may extend in the left-right direction and may extend circumferentially from the lower side of the nozzle head (210). The support member (230) may extend radially beyond the outer diameter of the space formed in the orifice (300). Accordingly, the support member (230) is supported by the orifice (300) to prevent the nozzle (200) from moving into the tube (400).

[0050] A tube (400) configured to store contents may include a soft tube body (410) configured to receive contents and a tube neck (420) coupled to an opening of the tube body (410). In this case, the tube body (410) may be omitted as needed.

[0051] The tube body (410) is provided with a thickness thinner than the tube neck (420) so that it can be easily deformed. The tube body (410) can be provided so that the contents located inside are moved toward the tube neck (420) by deforming its shape as it is pressurized. An opening is formed at one end of the tube body (410) so that 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 control the movement of the contents. The tube neck (420) may have a discharge hole (421H) formed therein to allow the contents to pass through. More specifically, the tube neck (420) may include an inlet portion (421) configured to cover the opening of the tube body (410). Based on FIG. 2, the inlet portion (421) may extend in the left and right directions. The discharge hole (421H) is formed in the inlet portion (421), so that the contents discharged from the tube body (410) can move through the discharge hole (421H). At this time, the discharge hole (421H) has a cross-sectional area smaller than the opening of the tube body (410), thereby reducing the discharge amount of the contents. As the discharge amount of the contents is reduced, it is easier to control the discharge amount of the contents. The inlet portion (421) may include a concave portion facing the orifice (300) and extending away from the orifice (300) so as to correspond to the shape of the orifice (300). The inlet portion (421) may form a tube passage (P1) between itself and the orifice (300). The tube passage (P1) may be defined as a passage (P) extending from the discharge hole (421H) to the orifice passage (P2) described later. Due to the shape of the inlet portion (421) corresponding to the orifice (300), the cross-sectional area of ​​at least one part of the tube passage (P1) may be maintained constant so that the flow of contents is not 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. The connecting rib (422) is described in more detail in the description of the orifice (300) that is connected to the connecting rib (422).

[0053] An orifice (300) configured to limit the discharge amount of contents to a predetermined value or less may be provided. The orifice (300) may be provided such 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 such that at least a portion thereof is received in the nozzle neck (220) to reduce the cross-sectional area of ​​the flow path (P) through which the contents can move. If the orifice (300) is not provided, the flow path (P) formed between the discharge hole (421H) and the discharge hole (201H) may be defined only by the nozzle (200). The orifice (300) may be received in the nozzle (200) to form a flow path (P) with a cross-sectional area smaller than that of the flow path (P) defined only by the nozzle (200). If the area of ​​the flow path (P) is narrowed, the amount of contents passing through the flow path (P) may be reduced. Accordingly, the amount or speed of the contents 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) through which the contents can move between the inner wall of the nozzle neck (220) and the orifice (300) so that the contents can move. However, if necessary, when the nozzle neck (220) is not received by the tube neck (420) but rather the nozzle neck (220) receives the tube neck (420), the orifice (300) may be received inside the tube neck (420), and an orifice flow path (P2) may be formed between the inner wall of the tube neck (420) and the orifice (300). For reference, the orifice (300) may have a rubber material. Accordingly, the sealing effect with the contacting components of the orifice (300) can be improved, and deformation can be easily achieved.

[0054] As shown in FIG. 3(a), an inwardly concave channel groove (311H) may be formed to form an orifice channel (P2) in the orifice (300). As shown in FIG. 2, the orifice channel (P2) may be defined by the inner wall of the nozzle neck (220) and the channel groove (311H). If necessary, the orifice channel (P2) may be formed between the outer surface of the orifice (300) and the inner wall of the nozzle neck (220) without the channel groove (311H) being provided. However, when the orifice channel (P2) is formed by forming the channel groove (311H), the amount of contents discharged can be easily controlled by adjusting the area and number of the channel grooves (311H).

[0055] The Euro groove (311H) can be extended parallel to the longitudinal direction of the nozzle neck (220). As the Euro groove (311H) is parallel to the longitudinal direction of the nozzle neck (220), the extension direction of the orifice flow path (P2) can be parallel to the extension direction of the nozzle neck (220). The extension direction of the nozzle neck (220) can be parallel to the extension direction of the nozzle flow path (P3)(P), and thus the orifice flow path (P2) can be parallel to the nozzle flow path (P3)(P). Accordingly, contents exiting the orifice flow path (P2) can be easily moved to the nozzle flow path (P3)(P).

[0056] Furthermore, if necessary, the cross-sectional area of ​​the orifice channel (P2) may vary along the longitudinal direction. If the cross-sectional area of ​​the orifice channel (P2) increases as it moves toward the discharge hole (201H), the discharge speed of the contents may be further slowed down.

[0057] As illustrated in FIG. 3(a), the orifice (300) may have a through hole (321H) formed on the lower side of the flow path groove (311H). The contents may be configured to move from the tube flow path (P1) to the orifice flow path (P2) through the through hole (321H). That is, the through hole (321H) may be configured to allow the movement of contents from the discharge hole (421H) toward the flow path groove (311H).

[0058] The through hole (321H) may be adjacent to the flow groove (311H). Accordingly, bending of the flow path (P) formed from the through hole (321H) to the flow groove (311H) is prevented, so that energy loss due to friction can be reduced as contents flowing into the through hole (321H) move into the flow groove (311H).

[0059] A flow path (P) formed to allow contents to flow from the discharge hole (421H) to the discharge hole (201H) may be formed to be bent at least once by an 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 (P3)(P). Contents heading from the discharge hole (421H) toward the tube flow path (P1) may be bent and moved while moving toward the orifice flow path (P2). Since the orifice flow path (P2), formed between the inner wall of the nozzle neck (220) and the orifice, extends upward and then is bent to the right, the contents may be bent and moved along the orifice flow path (P2). Contents exiting the orifice flow path (P2) may be bent upward again while heading toward the nozzle flow path (P3)(P). As illustrated in FIG. 2, the flow path (P) configured to allow the contents to move can be bent four times when defined as being bent while moving from the discharge hole (421H) to the tube flow path (P1). When the flow path (P) is bent, energy loss of the contents flow may occur in the bent portion, thereby delaying the discharge of the contents.

[0060] The orifice (300) is explained in more detail.

[0061] The orifice (300) may include a nozzle insertion part (310) inserted into the nozzle (200), a tube opposing part (320) extending from the nozzle insertion part (310) in a direction different from the extension direction of the nozzle insertion part (310), a nozzle support part (330) extending from the tube opposing part (320) in a direction different from the extension direction of the tube opposing part (320), a tube cover part (340) extending in a direction different from the extension direction of the nozzle support part (330), and / or a flange part (350) extending in a direction different from the extension direction of the tube cover part (340). At this time, the nozzle support part (330), the tube cover part (340), and the flange part (350) may be omitted as necessary.

[0062] The nozzle insert (310) can be inserted into the nozzle neck (220). The nozzle insert (310) may be substantially annular and extend in the vertical direction. The nozzle insert (310) may face the inner surface of the nozzle neck (220). The aforementioned flow groove (311H) may be formed in the nozzle insert (310). The portion of the nozzle insert (310) where the flow groove (311H) is not formed may be in close contact with the inner surface of the nozzle neck (220) to prevent contents from moving between the nozzle neck (220) and the nozzle insert (310).

[0063] The tube opposing portion (320) may be located on the side facing the discharge hole (421H) of the nozzle neck (220). In other words, the tube opposing portion (320) may be located on the lower side of the nozzle insertion portion (310). The tube opposing portion (320) may be received in the tube neck (420). The tube opposing portion (320) may face the inlet portion (421) of the tube neck (420). The tube opposing portion (320) may include a convex portion (322) that connects the nozzle insertion portion (310) and faces the discharge hole (421H). A portion of the tube passage (P1) formed between the convex portion (322) and the inlet portion (421) of the tube neck (420) is formed to be inclined toward the through hole (321H) by the convex portion (322), thereby reducing the bending angle of the passage (P) located between the tube passage (P1) and the through hole (321H). The tube passage (P1) formed between the convex portion (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 opposing portion (320) is a portion extending outward from the convex portion (322) and may further include a portion supporting the lower end of the nozzle neck (220). The aforementioned through hole (321H) may be formed in the tube opposing portion (320).

[0064] At this time, the orifice (300) may have an opening formed toward the discharge hole (201H) and a concave space (310S) formed toward the discharge hole (421H). More specifically, an opening may be formed on the upper side of the concave space (310S). The concave space (310S) may be formed by the nozzle insertion part (310) and the convex part (322). The nozzle insertion part (310) may be easily deformed inward by the concave space (310S). Since the nozzle insertion part (310) is inserted into the nozzle neck (220) and is positioned to be in contact with the inner surface of the nozzle neck (220), it may not be easy to insert into the nozzle neck (220). By forming the concave space (310S), the nozzle insertion part (310) may be easily inserted into the nozzle neck (220).

[0065] The nozzle support (330) may extend in an upward and downward direction from the outside of the tube opposing portion (320). The nozzle support (330) may be positioned between the nozzle (200) and the tube neck (420). The nozzle support (330) may be configured to prevent the movement of contents between the nozzle (200) and the tube neck (420). More specifically, the space between the nozzle neck (220) and the orifice (300) may be sealed by the nozzle insertion portion (310), the tube opposing portion (320), and the nozzle support (330) contacting the nozzle neck (220), thereby preventing the contents from leaking between the nozzle neck (220) and the orifice (300).

[0066] Furthermore, the nozzle support (330) may be extended outwardly at an angle as it extends upward. The nozzle support (330) may be in contact with the inner wall of the tube neck (420) and may be coupled to the tube neck (420). As the nozzle support (330) is inclined, the nozzle support (330) may be coupled to the tube neck (420) by a press fit. In particular, since the upper end of the nozzle support (330) is positioned at a height corresponding to the opening of the concave space (310S), the nozzle support (330) may be deformed inward while the nozzle support (330) is inserted into the tube neck (420), and accordingly, the insertion of the nozzle support (330) may be easy. After the nozzle support (330) is inserted into the tube neck (420), a force is generated to restore the orifice (300) to its original state, causing the nozzle support (330) and the tube neck (420) to be in close contact, thereby strengthening the connection between the orifice (300) and the tube neck (420).

[0067] The nozzle support portion (330) may include a support projection (332) that protrudes downward from the tube opposing portion (320) and is supported by the tube neck (420). Accordingly, the support projection (332) can maintain a gap between the tube opposing portion (320) and the inlet portion (421) of the tube neck (420), thereby forming a tube passage (P1) through which contents can pass. Furthermore, the support projection (332) seals the gap with the tube neck (420), preventing the contents from leaking between the nozzle support portion (330) and the tube neck (420).

[0068] The nozzle neck (220) may include a coupling projection (221) that protrudes toward the nozzle support (330). The coupling projection (221) may protrude radially outward from the nozzle neck (220). The nozzle support (330) may have a nozzle coupling groove (331H) formed therein that accommodates the coupling projection (221). The nozzle coupling groove (331H) may be formed to correspond to the coupling projection (221). By receiving the coupling projection (221) in the nozzle coupling groove (331H), the orifice (300) can be coupled to the nozzle (200).

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

[0070] The tube cover portion (340) can be detachably coupled to the tube neck (420). The tube neck (420) may include a coupling rib (422) that protrudes toward the tube cover portion (340). The tube cover portion (340) may have a tube coupling groove (341H) formed therein that accommodates the coupling rib (422). 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 upper side to the lower side. Accordingly, insertion of the coupling rib (422) into the tube coupling groove (341H) may be easy. By means of the coupling rib (422) and the tube coupling groove (341H), the orifice (300) can be detachably coupled to the tube neck (420). In other words, the nozzle (200) and the orifice (300) can be combined to form a cap assembly (CA) that is detachable from the tube neck (420). In other words, by forming a modular cap assembly (CA) with the cap (100), the nozzle (200), and the orifice (300), the assembly configuration with the tube (400) can be simplified, and the diameter of the tube (400) can be expanded.

[0071] The tube cover portion (340) may include a cap coupling portion (341) that protrudes outward. The cap coupling portion (341) may be a part that is coupled to the cap (100). The cap (100) may have a corresponding part that is screw-coupled to the cap coupling portion (341). Accordingly, the cap (100) may be coupled to or separated from the orifice (300) by rotation.

[0072] The flange portion (350) may protrude outward from the tube cover portion (340). The flange portion (350) may contact the tube (400) to finally seal any contents that may leak between the tube (400) and the orifice (300). Furthermore, the flange portion (350) may support the cap (100) to limit the radius of rotation for the cap (100) to be coupled with the orifice (300).

[0074] Other embodiments in addition to the above examples are described below. Content common to the above examples will be omitted as much as possible, and the other embodiments will be described focusing on the differences. In other words, it is evident that if content not explained in other embodiments is necessary, it can be supplemented through the content of the above examples.

[0075] FIG. 3(b) illustrates an orifice (300) according to a second embodiment of the present invention.

[0076] Referring to FIG. 3(b), an orifice (300) according to a second embodiment of the present invention will be described.

[0077] The second embodiment differs from the first embodiment in that a plurality of Euro grooves (311H-1) are formed in the orifice (300).

[0078] The Euro grooves (311H-1) may be provided in multiple numbers. The number of multiple Euro grooves (311H-1) may be provided to correspond to the viscosity of the contents. That is, if the viscosity of the contents increases, the number of multiple Euro grooves (311H-1) may increase accordingly. If the viscosity of the contents decreases, the number of Euro grooves (311H-1) may decrease accordingly. As a result, even though the viscosity of the contents changes, the amount or speed of the contents discharged through the discharge hole (201H) can be set to a constant amount to the desired degree.

[0079] Furthermore, multiple flow channels (311H-1) can be formed at a distance or angle that is as far apart as possible from each other. As shown in FIG. 3(b), when two flow channels (311H-1) are formed, they can be positioned at an angle of 180° to each other. Accordingly, interference between the flow of contents entering each flow channel (311H-1) can be prevented.

[0080] Additionally, through holes (321H) may also be provided in multiple numbers corresponding to the Euro groove (311H-1).

[0082] FIG. 4 is a cross-sectional view and an enlarged view of a contents container (1) and an orifice (300) according to another embodiment of the present invention. More specifically, FIG. 4(a) is a cross-sectional view relating to a contents container (1) and an orifice (300) according to a third embodiment. FIG. 4(b) is a cross-sectional view relating to a contents container (1) and an orifice (300) according to a fourth embodiment.

[0083] The third and fourth embodiments differ from the first embodiment in that the shape of the Euro groove (311H-2, 311H-3) is formed to form a plurality of Euros (P).

[0084] The flow grooves (311H-2, 311H-3) can form multiple flow channels (P). As the number of flow channels (P) formed by the flow grooves (311H-2, 311H-3) increases, the total cross-sectional area of ​​the flow grooves (311H-2, 311H-3) can increase. The number of flow channels (P) formed by the flow grooves (311H-2, 311H-3) can be arranged to correspond to the viscosity of the contents. That is, if the viscosity of the contents increases, the number of flow channels (P) formed by the flow grooves (311H-2, 311H-3) can increase in correspondence. If the viscosity of the contents decreases, the number of flow channels (P) formed by the flow grooves (311H-2, 311H-3) can decrease in correspondence. As a result, even though the viscosity of the contents varies, the amount or speed of the contents discharged through the discharge hole (201H) can be set to a constant amount as intended.

[0085] At this time, the third embodiment illustrated in FIG. 4(a) illustrates a case where the Euro groove (311H-2) is a single one, and the fourth embodiment illustrated in FIG. 4(b) illustrates a case where two Euro grooves (311H-3) are formed, as in the second embodiment, as in the third embodiment.

[0087] FIG. 5 is a cross-sectional view and an enlarged view of a contents container (1) and an orifice (300) according to another embodiment of the present invention. More specifically, FIG. 5(a) is a cross-sectional view relating to a contents container (1) and an orifice (300) according to a fifth embodiment. FIG. 5(b) is a cross-sectional view relating to a contents container (1) and an orifice (300) according to a sixth embodiment.

[0088] The 5th and 6th embodiments differ from the 1st embodiment in that the shape of the flow groove (311H-4, 311H-5) is different and the flow recess (312H-5) is formed with a different end shape of the orifice flow (P2). In particular, the 4th and 5th embodiments differ in that the flow groove (311H-4, 311H-5) forms a single flow (P) while only the shape of the flow groove (311H-4, 311H-5) is different.

[0089] The cross-section of the Euro groove (311H-4, 311H-5) may be rectangular. If necessary, the cross-sectional shape of the Euro groove (311H-4, 311H-5) may have a specific shape. Furthermore, the area of ​​the Euro groove (311H-4, 311H-5) may be changed according to the viscosity of the contents to determine the discharge amount of the contents.

[0090] Furthermore, a downwardly concave flow path recess (312H-5) may be formed at the upper end of the nozzle insertion portion (310) of the orifice (300). The orifice flow path (P2) portion on the side where the flow path recess (312H-5) is formed may have a flow path (P) with a wider cross-sectional area than the orifice flow path (P2) portion in the first embodiment. Accordingly, the contents flowing along the flow path recess (312H-5) may experience less energy loss.

[0091] At this time, the fifth embodiment illustrated in FIG. 5(a) illustrates a case where the Euro groove (311H-4) is a single one, and the sixth embodiment illustrated in FIG. 5(b) illustrates a case where two Euro grooves (311H-5) are formed, as in the second embodiment, as in the fifth embodiment.

[0093] FIG. 6 is a cross-sectional view and enlarged view of a contents container (1) and an orifice (300) according to another embodiment of the present invention. More specifically, FIG. 5 is a cross-sectional view relating to a contents container (1) and an orifice (300-6) according to a seventh embodiment of the present invention.

[0094] Referring to FIG. 6, an orifice (300-6) according to the seventh embodiment of the present invention will be described.

[0095] 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 the orifice (300-6) has a protrusion (360-6).

[0096] The through hole (321H-6) may be connected to the flow groove (311H-6) and be an inwardly concave groove. Here, the term "hole" can be understood to mean including the groove. By connecting the through hole (321H-6) and the flow groove (311H-6), energy loss can be minimized while the contents moving from the through hole (321H-6) to the flow groove (311H-6) flow.

[0097] At this time, the through hole (321H-6) may be formed in the tube-opposing portion (320-6) extending outward from the lower side of the nozzle insertion portion (310-6).

[0098] The orifice (300-6) may include a protrusion (360-6) that protrudes outward from the nozzle insertion part (310-6). The protrusion (360-6) may seal the space between the inner surface of the nozzle neck (220) and the nozzle insertion part (310-6). The protrusion (360-6) may be provided in multiple numbers and arranged vertically.
