Description

Technology Field

[0001] The present invention relates to a quantitative dispensing container, and in particular to a container for dispensing a quantitative amount of contents contained within the container. Background Technology

[0002] With the recent increase in single-person households, there is a growing demand for recipes that are easy and simple to prepare, and consumer purchasing trends at supermarkets are also showing an increasing demand for 'fresh products' and 'seasonings'.

[0003] For example, seasoning containers such as salt, pepper, and Miwon are typically stored and used as dispensing containers consisting of a main body that holds a certain amount of powdered seasoning and a lid with multiple dispensing holes. However, since such dispensing containers cannot accurately measure the amount to be used, there is a problem in that the required amount of seasoning must be dispensed arbitrarily through the dispensing holes based on intuition.

[0004] To solve this problem, Korean Registered Patent Publication No. 10-0916614 provides a powder quantitative dispensing container capable of conveniently dispensing a precise amount of a powder product; however, it has the problem of a complex structure, being inconvenient to carry, and being unable to check what type and amount of powder remains inside.

[0005] The aforementioned background technology is one that the inventor possessed or acquired in the process of deriving the content of the disclosure of the present application, and it cannot be considered as prior art disclosed to the general public prior to the filing of this application. The problem to be solved

[0006] One objective according to an embodiment of the present invention is to provide a quantitative dispensing container capable of measuring a fixed amount of contents and dispensing it to the outside through simple operation.

[0007] One objective according to an embodiment of the present invention is to provide a quantitative dispensing container that enables easy separation and recycling by providing a cap assembly formed of a plastic material. means of solving the problem

[0008] A quantitative dispensing container according to one embodiment may include: a container body having an internal space for receiving contents and a discharge port formed at the top for discharging the contents; and a stopper assembly connected to the container body to communicate with the discharge port and configured to discharge a certain amount of the contents. The stopper assembly may include: a lower stopper connected to the top of the container body and having a lower opening formed through in the vertical direction to communicate with the discharge port; an upper stopper connected to the top of the lower stopper and having an upper opening formed through in the vertical direction to communicate with the outside; and a first push member disposed between the lower stopper and the upper stopper, having a first hollow formed through in the vertical direction, and movable between a first position and a second position moved in a first direction perpendicular to the vertical direction from the first position. When the first push member is in the first position, the first hollow overlaps with the lower opening, and when the first push member is in the second position, the first hollow may overlap with the upper opening.

[0009] The first push member may be configured to move from the first position to the second position when a pressing force is applied in the first direction, and to return to the first position from the second position when the pressing force is removed.

[0010] The lower stopper may include a first stopper portion in which the first opening is formed; and a side wall formed protruding from the upper circumference of the first stopper portion to form a space in which the first push member is disposed. At least a portion of the side wall may be formed open so as not to restrict the movement of the first push member between the first position and the second position.

[0011] The first push member may include a first push portion having a first hollow formed therein; and an elastic portion connected to the first push portion in the first direction and having elastic force. The elastic portion may be configured to contact the inner circumferential surface of the side wall of the lower stopper, partially bend as the first push member moves from the first position to the second position to store elastic energy, and to return the first push member to the first position through the stored elastic energy.

[0012] The above quantitative dispensing container may further include a second push member coupled to the first push member, which moves together with the first push member between the first position and the second position, and which is partially exposed to the outside of the stopper assembly through the open side wall of the lower stopper. The second push member may include a cover portion positioned to cover the upper part of the first push member; a second push portion formed to protrude downward from the cover portion and inserted into the first hollow of the first push member; and a second hollow formed to penetrate the cover portion and the second push portion in the vertical direction.

[0013] When the second push member is in the second position, the end of the cover portion facing the first direction contacts the side wall of the lower plug, thereby restricting the movement of the second push member in the first direction.

[0014] The second push member may further include a stopper formed protruding from the side. When the second push member is in the first position, the stopper may contact the side wall of the lower plug to restrict the movement of the second push member in a second direction opposite to the first direction.

[0015] The first push member may further include a connecting portion connected to the first push portion in a second direction opposite to the first direction. The connecting portion may be engaged and coupled to the inner circumference of the second push member.

[0016] The upper stopper comprises: a second stopper portion having the second opening formed therein; and a flange formed protruding from the lower circumference of the second stopper portion and detachably coupled to the side wall of the lower stopper, wherein at least a portion of the flange may be formed open so as not to restrict the movement of the first push member between the first position and the second position.

[0017] The second push member further includes an upper stopper formed protruding from the top of the cover portion, and the upper stopper can restrict the movement of the second push member in the first direction by contacting the second stopper portion of the upper stopper when the second push member is positioned at the second position. Effects of the invention

[0018] The quantitative dispensing container according to the present invention can dispense a fixed amount of contents stored inside the container body to the outside by measuring and dispensing the amount of contents through a hollow formed in the push member.

[0019] A quantitative dispensing container according to one embodiment is formed such that the first opening of the lower cap and the second opening of the upper cap do not overlap, and by moving the contents between the first opening and the second opening through the positional movement of a push member, additional mixing and leakage of contents can be prevented when dispensing the measured contents to the outside.

[0020] The effects of the quantitative dispensing container according to one embodiment are not limited to those mentioned above, and other unmentioned effects will be clearly understood by a person skilled in the art from the description below. Brief explanation of the drawing

[0027] The shape of the quantitative dispensing container (1) shown in the drawing is exemplary and can be modified into various forms within the scope that does not impair the technical concept of the present invention. Meanwhile, for convenience of explanation, the drawing shows the quantitative dispensing container (1) in a stored state; however, it should be noted that when the quantitative dispensing container (1) is used, it is used in an inverted state, that is, with the stopper assembly (10) located at the bottom, unlike what is shown in the drawing.

[0028] Referring to FIGS. 1 to 4b, a quantitative dispensing container (1) according to one embodiment can be used to store contents inside and to discharge the stored contents to the outside in a certain amount, for example, a set quantitative amount.

[0029] In one embodiment, the contents that can be stored in the quantitative dispensing container (1) are not particularly limited, but are preferably substances that need to be used in a fixed amount, and may be, for example, powdered or liquid substances such as seasonings, food products, or cosmetics.

[0030] In one embodiment, the quantitative dispensing container (1) may include a container body (20) in which contents are stored, and a stopper assembly (10) coupled to the container body (20) to discharge a certain amount of contents stored in the container body (20) to the outside.

[0031] In one embodiment, the container body (20) may include a main body portion (220) that forms an internal space (220a) in which contents are received. An opening (200a) communicating with the internal space (220a) may be formed at the top of the container body (20) so that contents received in the internal space (220a) are discharged.

[0032] In one embodiment, a container coupling portion (210) may be formed on the upper part of the container body (20) for coupling with the stopper assembly (10), for example, to be coupled to the lower stopper (100) described later. The container coupling portion (210) may have screw threads formed on its outer surface, for example as shown in the drawing, and may be coupled to the stopper assembly (10) through screw coupling, but may also be coupled to the stopper assembly (10) by a press fit method. For example, it should be noted that the method of coupling the container body (20) with the stopper assembly (10) is not separately limited, and various known coupling structures may be applied.

[0033] In one embodiment, the container body (20) may be formed of plastic or glass, but the material is not particularly limited. For example, if the container body (20) is formed of the same type of plastic material as the cap assembly (10), there is an advantage that when disposing of the metered-dispensing container (1) after use, the container body (20) and the cap assembly (10) can be separated for recycling without being separated. Since the container body (20) can be formed in various shapes and materials capable of holding contents, further description thereof will be omitted.

[0034] In one embodiment, the stopper assembly (10) may be connected to the container body (20) so as to be in communication with the discharge port (200a), and configured to discharge a certain amount of the contents inside the container body (20) discharged through the discharge port (200a) to the outside.

[0035] In one embodiment, the plug assembly (10) may be formed of a plastic material.

[0036] In one embodiment, the stopper assembly (10) may include a lower stopper (100), an upper stopper (130), a first push member (110), and a second push member (120). As shown in FIG. 2, the lower stopper (100), the first push member (110), the second push member (120), and the upper stopper (130) may be connected to be arranged sequentially from the top of the container body (20) to form the stopper assembly (10).

[0037] In one embodiment, the lower stopper (100) may be connected to the top of the container body (20). The lower stopper (100) may include a first stopper portion (100b), a lower connecting portion (101), and a side wall (102).

[0038] In one embodiment, with the lower stopper (100) connected to the container body (20), the first stopper portion (100b) can cover the discharge port (200a). In one embodiment, the first stopper portion (100b) can be formed in the shape of a plate having a circular shape. In one embodiment, a lower opening (100a) can be formed in the first stopper portion (100b) that penetrates in the vertical direction and communicates with the discharge port (200a). The contents inside the container body (20) can be discharged to the outside of the lower stopper (100) through the lower opening (100a).

[0039] In one embodiment, the lower stopper (100) may be directly connected to the container body (20) through a lower connecting portion (101) formed at the bottom of the first stopper portion (100b). The lower connecting portion (101) may be configured to accommodate the upper portion of the container body (20), for example, the container connecting portion (210). For example, the lower connecting portion (101) may form a space into which the container connecting portion (210) can be inserted, and the space formed by the lower connecting portion (101) may be formed in a shape and size that allows the container connecting portion (210) to be forcibly fitted. If a screw thread is formed on the outer surface of the container connecting portion (210), a screw thread may be formed on the inner surface (105) of the lower connecting portion (101) to engage with and screw-couple to the screw thread formed on the container connecting portion (210).

[0040] In one embodiment, the lower stopper (100) may include a side wall (102) formed on at least a portion of the upper circumference of the first stopper portion (100b). For example, if the first stopper portion (100b) is formed in the shape of a circular plate, the side wall (102) may be formed in an arc shape that wraps around the circumferential circumference of the first stopper portion (100b). In one embodiment, the side wall (102) of the lower stopper (100) may form a space in which the first push member (110) and the second push member (120), which will be described later, can be placed. In one embodiment, the side wall (102) formed on the lower stopper (100) is formed with at least a portion open in the horizontal direction (e.g., +X direction), thereby enabling movement of the first push member (110) and the second push member (120) described later in the first direction (e.g., the first direction (D1) of FIG. 6b) and the second direction (e.g., the second direction (D2) of FIG. 6b).

[0041] In one embodiment, the side wall (102) of the lower stopper (100) may include an insertion groove (100c) formed on the upper side. The flange (131) of the upper stopper (130), which will be described later, may be inserted into the insertion groove (100c).

[0042] In one embodiment, the upper plug (130) may be connected to the upper part of the lower plug (100) to form the upper part of the plug assembly (10). The upper plug (130) may include a second plug portion (132) and a flange (131).

[0043] In one embodiment, the second stopper portion (132) may cover the upper portion of the lower stopper (100). The shape of the second stopper portion (132) may be formed in a shape corresponding to the shape of the lower stopper (100). In one embodiment, the second stopper portion (132) may have an upper opening (130a) formed through it in the vertical direction so that the contents of the container body (20) can be discharged to the outside. The upper opening (130a) may be formed in the portion of the second stopper portion (132) that does not overlap with the lower opening (100a) formed in the lower stopper (100) when the stopper assembly (10) is viewed from above. For example, the lower opening (100a) and the upper opening (130a) may not overlap each other along the vertical direction. Based on the view of the stopper assembly (10) from above, the upper opening (130a) may be located in a first direction (e.g., -X direction) relative to the lower opening (100a). In this case, it may be configured to prevent the contents from being directly discharged from the lower opening (100a) to the upper opening (130a) when the quantitative dispensing container (1) is inverted.

[0044] Although not shown in the drawing, the upper stopper (130) may include a support portion (not shown) formed on the top of the second stopper portion (132) to support the quantitative dispensing container (1) against the ground. As previously mentioned, since the quantitative dispensing container (1) is used in an inverted state rather than as shown in the drawing to discharge the contents, the second stopper portion (132) can be stored upside down with a certain distance from the ground through the support portion.

[0045] A flange (131) may be formed protruding downward around the lower perimeter of the second stopper portion (132). The flange (131) may be formed to encircle at least a portion of the perimeter of the second stopper portion (132). In this case, the flange (131) formed on the upper stopper (130) may be configured so as not to restrict movement in the first direction (e.g., the first direction (D1) in FIG. 6b) and the second direction (e.g., the second direction (D2) in FIG. 6b) of the first push member (110) and the second push member (120) described later, by being formed so that at least a portion is open in the horizontal direction (e.g., the +X direction), just like the side wall (102) of the lower stopper (100). In one embodiment, the height of the flange (131) may be formed in a shape corresponding to the height of the side wall (102) formed on the lower stopper (100). When the upper plug (130) is coupled to the lower plug (100) through the flange (131), a space may be formed between the lower plug (100) and the upper plug (130) in which the first push member (110) and the second push member (120) can be movably positioned.

[0046] In one embodiment, the first push member (110) and the second push member (120) can perform the function of receiving a measured amount of the contents discharged through the lower opening (100a) and discharging the measured contents to the outside through the upper opening (130a).

[0047] In one embodiment, the first push member (110) and the second push member (120) may be movably positioned within the space formed between the lower stopper (100) and the upper stopper (130). Meanwhile, in the disclosed embodiment, the first push member (110) and the second push member (120) are illustrated and described as being coupled together and moving as a single unit; however, it is noted that an embodiment in which only the first push member (110) is used with the second push member (120) omitted, unlike the illustrated embodiment, is also possible.

[0048] In one embodiment, the first push member (110) may be movably positioned between the lower plug (100) and the upper plug (130). In one embodiment, the first push member (110) may move between a first position and a second position located in a first direction perpendicular to the up-down direction from the first position. For example, the first position may mean a position where the first push member (110) has moved as far as possible in the +X direction (e.g., the state of FIG. 5b). The second position may mean a position where the second push member (120) has moved as far as possible in the -X direction (e.g., the state of FIG. 6b).

[0049] In one embodiment, the first push member (110) may include a first hollow (110a) (e.g., Z-axis) formed through the vertical direction. For example, the first push member (100) may perform the function of receiving a certain amount of contents through the first hollow (100a) and moving the certain amount of contents received in the first hollow (100a) so that it can be discharged to the outside of the stopper assembly (10).

[0050] In one embodiment, depending on the position of the first push member (100), the first hollow (110a) may be in communication with the lower opening (100a) or the upper opening (130a). For example, when viewed from above (e.g., in the Z-axis direction), as the first push member (100) moves between the first position and the second position, the position of the first hollow (100a) may change between the lower opening (100a) and the upper opening (130a). For example, when the first push member (110) is in the first position as in FIG. 5B, the first hollow (110a) of the first push member (110) may overlap with the lower opening (100a) of the lower plug (100). In this case, the upper end of the first hollow (110a) is covered by the upper stopper (130), and the lower end of the first hollow (110a) is connected to the lower opening (100a), so that contents discharged from the discharge port (200a) through the lower opening (100a) can be received within the first hollow (110a). On the other hand, when the first push member (110) is pressed in the first direction and moves to the second position as shown in FIG. 6b, the second hollow (120a) of the second push member (120) can overlap with the upper opening (130a) of the upper stopper (130). In this case, the bottom of the first hollow (110a) is covered by the lower stopper (100), and the top of the first hollow (110a) is connected to the upper opening (130a), so that the contents contained within the first hollow (110a) can be discharged to the outside of the stopper assembly (10) through the discharge port (200a). That is, the first push member (110) can move the contents between the lower opening (110a) and the upper opening (130a) through the first hollow (110a).

[0051] In one embodiment, the first push member (110) can transfer a certain amount of contents between the lower opening (110a) and the upper opening (130a) through the first hollow (100a). For example, the amount of contents transferred at once between the lower opening (110a) and the upper opening (130a) through the operation of the first push member (110) can be maintained constant according to the volume of the first hollow (110a), that is, the capacity of the first hollow (110a). Accordingly, the first hollow (110a) can function as a measuring cup that measures the amount of contents and discharges it to the outside.

[0052] In one embodiment, the capacity (i.e., volume) of the first hollow (110a) may be determined differently depending on the type of contents contained within the quantitative dispensing container (1). For example, if the contents contained within the quantitative dispensing container (1) are seasonings such as sugar or salt, the capacity of the first hollow (110a) may be formed to correspond to the measurement unit of the seasoning (e.g., 1 / 16 tsp (about 0.3 ml)). As another example, if the contents contained within the quantitative dispensing container (1) are cosmetics such as skin lotion, the capacity of the first hollow (110a) may be formed to correspond to the appropriate amount of the cosmetic used once (e.g., 0.5 ml).

[0053] In one embodiment, the capacity of the first hollow (110a) can be determined according to the height of the first hollow (110a), so that the amount of contents discharged once through the stopper assembly (1) can be easily controlled by forming the height of the first hollow (110a) differently depending on the type of contents. It should be noted that the gap between the lower stopper (100) and the upper stopper (130) can also be changed correspondingly according to the height of the first hollow (110a).

[0054] In one embodiment, when the first push member (110) is between the first position and the second position, the first hollow (110a) can be sealed at the top and bottom by the first stopper member (100) and the second stopper member (130) so that the contents contained inside do not leak out. For example, the bottom of the first hollow (110a) can be in close contact with the first stopper portion (100b), and the top of the first hollow (110a) can be in close contact with the second stopper portion (132) through the second push member (120). If the second push member (120) is omitted, the bottom and top of the first hollow (110a) can be in close contact with the first stopper portion (100b) of the lower stopper (100) and the second stopper portion (132) of the upper stopper (120). Accordingly, the contents can be introduced into the first hollow (110a) or discharged from the first hollow (110a) only through the lower opening (100b) or the upper opening (130a).

[0055] In one embodiment, the first push member (110) may be configured to be positioned at a first position without any external force acting upon it. For example, the first push member (110) may be configured to move from the first position to the second position when subjected to a pressure in the first direction (e.g., -X direction), but to return to its original position from the second position to the first position when the pressure is removed. A detailed structure thereof will be described later.

[0056] Referring to FIGS. 3a and 3b, the first push member (110) may include a formed first push portion (114), an elastic portion (111), and a connecting portion (112).

[0057] In one embodiment, a first hollow (110a) may be formed in the first push portion (114). The first hollow (110a) may be formed to have a cross-sectional shape substantially identical to the first opening. The first push portion (114) may be formed in a ring shape surrounding the first hollow (110a).

[0058] In one embodiment, the elastic portion (111) may be connected to the first push member (110) in a first direction (e.g., -X direction). For example, the elastic portion (111) may be formed in the shape of a plate having elastic force. In one embodiment, the elastic portion (111) may be in contact with the inner circumferential surface (105) of the side wall (102) formed by the lower stopper (100), and may perform the function of storing elastic energy according to the position change of the first push member (110) between the lower stopper (100) and the upper stopper (130) to restore the first push member (110) to its original position. For example, a catch portion protruding inward may be formed on the inner circumferential surface (105) of the side wall (102) of the lower stopper (100), and both ends of the elastic portion (111) may be in contact with the catch portion. In this case, as the first push member (110) moves in the first direction, moving from a first position as in FIG. 5b to a second position as in FIG. 6b, the elastic part (111) can partially bend and store elastic energy while both ends are in contact with the inner circumferential surface (105) of the side wall (102). By the stored elastic energy, the elastic part (111) can apply an elastic force in the second direction (e.g., +X direction) so that the first push member (110) can return to its original position, e.g., the first position.

[0059] In one embodiment, the connecting portion (112) may be connected to the first push member (110) in a second direction (e.g., +X direction). The first push member (110) may be connected to the inner surface (105) of the second push member (120) through the connecting portion (112).

[0060] In one embodiment, the second push member (120) is positioned between the lower plug (100) and the upper plug (130) and is coupled with the first push member (110) so that it can move integrally with the first push member (110). In one embodiment, the second push member (120) can move between a first position and a second position together with the first push member (110). In one embodiment, the second push member (120) may be configured to be partially exposed to the outside of the plug assembly (10) so that the user can directly receive the pressure acting in a first direction. In one embodiment, the second push part (124) can perform the function of limiting the range of movement of the first push part (114) when moving between a first position and a second position together with the first push part (114).

[0061] In one embodiment, the second push member (120) may include a cover portion (121), a side portion (122), and a second push portion (124).

[0062] When the second push member (120) is coupled to the first push member (110), the cover portion (121) can cover at least a portion of the upper part of the first push member (110). In one embodiment, the end of the cover portion (121) facing the first direction (e.g., -X direction) is formed to protrude so as to contact the inner surface (105) of the side wall (102) of the lower plug (100) when the second push member (120) is in the second position, thereby performing the function of a stopper (1221) that restricts the second push member (120) and the first push member (110) connected to the second push member (120) from moving beyond the second position to the first direction.

[0063] In one embodiment, the second push member (120) may include an upper stopper (123) formed protruding from the top of the cover portion (121). The upper stopper (123) may restrict the second push member (120) from moving beyond the second position to the first direction (e.g., -X direction) by contacting the side of the second stopper portion (132) of the upper stopper (130) when the second push member (120) is positioned at the second position.

[0064] In one embodiment, the side portion (122) of the second push member (120) can cover the side of the first push member (110) exposed to the outside of the plug assembly (10), for example, the side of the first push member (110) located at the side wall (102) open at the first position. In one embodiment, the side portion (122) of the second push member (120) can be coupled by engaging with the connecting portion (112) of the first push member (110). For example, as shown in FIG. 3a, a coupling projection (1131) is formed on the connecting portion (112) of the first push member (110), and as shown in FIG. 4b, a coupling groove into which the coupling projection (1131) is inserted can be formed on the inner surface (105) of the side portion (122) of the second push member (120).

[0065] In one embodiment, the second push member (120) may include a stopper (1221) formed protruding from a side portion (122). The stopper (1221) may be formed protruding from both sides of the second push member (120) (e.g., in the + / - Y axis direction). The stopper (1221) formed on the side portion (122) contacts the inner surface (105) of the side wall (102) of the lower plug (100) when the second push member (120) is in a first position, thereby restricting the second push member (120) and the first push member (110) connected to the second push member (120) from moving beyond the first position in a second direction (e.g., in the +X direction).

[0066] In one embodiment, a stopper (1221) formed on the side portion (122) of the second push member (120) can prevent the second push member (120) from moving beyond the second position to the first direction by contacting a locking member (104) formed on the inner surface (105) of the side wall (102) of the lower plug (100) when the second push member (120) is pressed to the second position.

[0067] In one embodiment, the second push member (120) may include a second push portion (124) inserted into the first hollow (110a) of the second push member (120). The second push portion (124) may include a second hollow (120a) formed through a cross-sectional shape corresponding to the first hollow (110a) and extending in the vertical direction (e.g., Z-axis). In one embodiment, when the second push member (120) is coupled to the first push member (110), the second hollow (120a) may overlap and communicate with the first hollow (110a). In this case, when the first hollow (110a) communicates with the lower opening (100a) at the first position, the second hollow (120a) also communicates with the lower opening (100a), and when the first hollow (110a) communicates with the upper opening (130a) at the second position, the second hollow (120a) also communicates with the upper opening (130a). According to this structure, since the second push member (120) can be coupled to the first push part (114) in the vertical direction (e.g., Z-axis) through the second push part (124), the phenomenon of the coupling being released during the process of the second push member (120) and the first push member (110) moving in the first direction can be reduced or prevented. Meanwhile, although the drawings describe an embodiment in which the second push member (120) includes a second hollow (120a) formed in the second push portion (124), it should be noted that, as previously mentioned, the second push member (120) may be omitted, and an embodiment in which the second push member (120) is connected to the first push member (110) with the second push portion (124) omitted is also possible.

[0068] Through FIGS. 5a to 6b, the operation process of a quantitative dispensing container (1) according to one embodiment will be explained.

[0069] As illustrated in FIGS. 5a and 5b, when the first push member (110) is in the first position, the first hollow (110a) formed in the first push member (110) can be positioned to overlap with the lower opening (100a) of the lower stopper (100). Since the upper end of the first hollow (110a) is covered by the upper stopper (130) and the lower end of the first hollow (110a) is in communication with the lower opening (100a), when the user turns over the quantitative dispensing container (1), the contents contained inside the container body (20) can be contained within the first hollow (110a) (and the second hollow (120a)) through the dispensing port (200a) and the lower opening (100a). The first push member (110) can maintain its position in the first position by the elastic force exerted by the elastic part (111) when no separate external force is applied. A stopper (1221) formed on the side portion (122) of the second push member (120) contacts the inner surface (105) of the side wall (102) of the lower stopper (100), thereby restricting the second push member (120) and the first push member (110) from moving out of the first position and into the second direction (e.g., -X direction). In this case, the second push member (120) can be positioned so as to be exposed on the open side wall (102) of the lower stopper (100).

[0070] As illustrated in FIGS. 6a and 6b, when a user presses the second push member (120) in a first direction, the first push member (110) connected to the second push member (120) can move from a first position to a second position. As the first push member (110) moves to the second position, the elastic portion (111) of the first push member (110) is deformed and can store elastic energy. When the first push member (110) reaches the second position, the upper stopper (123) formed on the second push portion (124) contacts the upper cover to restrict the second push portion (124) from moving beyond the second position to the first direction.

[0071] Meanwhile, when the first push member (110) is positioned in the second position, the first hollow (110a) formed in the first push member (110) can be positioned to overlap with the upper opening (130a) of the upper stopper (130). Since the lower end of the first hollow (110a) is covered by a lower cover and the upper end of the first hollow (110a) is connected to the upper opening (130a), the contents contained within the first hollow (110a) can be discharged to the outside of the stopper assembly (10) through the upper opening (130a) while the quantitative dispensing container (1) is inverted. The contents discharged through the upper opening (130a) can be discharged in a constant amount corresponding to the volume of the first hollow (110a). When the pressing force applying the second push member (120) in the first direction is removed, the first push member (110) and the second push member (120) can return to the first position as in FIG. 5a by the restoring force of the elastic part (111).
