Description

Technical Field

[0001] The present invention relates to a discharge container, and particularly to a discharge container capable of discharging a small amount of liquid.

Background Art

[0002] Conventionally, squeeze containers have been used as containers for storing content liquids such as cosmetics and seasonings. In a squeeze container, when it is desired to discharge a small amount of the content liquid, if the body of the squeeze container is squeezed to discharge the liquid, more liquid than expected is discharged, and it is difficult to adjust the discharge amount of the content liquid. Therefore, it is also conceivable to attach a cap with a pump to the container body and operate the head of the pump to discharge the content liquid. However, the pump has a large number of parts and the cost is high.

[0003] For this reason, a discharge container has been conventionally known (see, for example, Patent Document 1) in which the central part of the top wall of a cap body with a nozzle fitted to the mouth part of the container body is formed of a spiral elastic cylinder with a small upper diameter, and the cylinder wall is sequentially made thinner from one end side of the cylinder wall part at either the upper or lower end to the other end cylinder wall part along the spiral direction of the spiral elastic cylinder. When discharging the content liquid, the container body is tilted, the small cylindrical part with a top at the upper end of the spiral elastic cylinder is pushed down, and after the thin part of the spiral elastic cylinder is elastically deformed, the thick part is sequentially elastically deformed. Thus, by causing the elastic deformation and elastic restoration, a small amount of the content liquid can be discharged.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the dispensing container described in Patent Document 1 above allows a small amount of liquid to be dispensed from the nozzle by pressing down the small cylinder at the top of the spiral elastic cylinder, but the spiral elastic cylinder, which is the operating part, does not easily deform elastically when dispensing the liquid, and furthermore, it is difficult to seal the nozzle after use.

[0006] The present invention aims to solve the above problems and provides a dispensing container that can be opened and closed simply by rotating the outer cap within a predetermined range, and can dispense a small amount of liquid by pressing the operating part of the outer cap. [Means for solving the problem]

[0007] To solve the above problems, the present invention adopts a configuration characterized by comprising: a container body comprising a body portion that contains the contents and has a shoulder portion formed at the top, a mouth portion formed above the body portion, and an elastic deformation portion formed between the shoulder portion and the mouth portion that can be bent and deformed in the axial direction; an inner cap comprising a mounting outer cylinder portion that is attached to the outer circumference of the mouth portion of the container body, a flow path formed on the inner circumference of the mounting outer cylinder portion that allows the contents to flow in the axial direction, and a stopper portion provided at the end of the flow path; an outer cylinder wall that is rotatably screwed onto the outer circumference of the mounting outer cylinder portion of the inner cap within a predetermined range, and whose lower end abuts against the shoulder portion of the container body and covers the elastic deformation portion when the lid is closed, a top wall portion having a discharge portion formed at the top of the outer cylinder wall, a pressable operating portion formed on the back side of the top wall portion, a sealing cylinder that is suspended from the lower surface of the top wall portion and seals the stopper portion of the inner cap when the lid is closed, and a discharge flow path that connects the discharge portion and the sealing cylinder.

[0008] As an embodiment of the discharge container, the inner cap comprises a cylindrical portion extending upward from the inner circumference of the mounting outer cylinder portion and a rotation-restricting recess cut out in a predetermined angular range on the outer circumference of the cylindrical portion, and the outer cap comprises an inner wall extending downward from the lower surface of the top wall portion into which the cylindrical portion of the inner cap is inserted, and a rotation-restricting rib protruding from the inner circumference of the inner wall, which enters into the rotation-restricting recess of the cylindrical portion and restricts the range of rotation, and the elastic deformation portion is formed in a bellows shape, and when the lid is opened, the elastic deformation portion deforms by pressing the operating portion of the outer cap, causing a small amount to be discharged from the discharge portion of the outer cap, and the container body comprises a locking projection protruding from the lower outer circumference of the lower end of the elastic deformation portion, and the outer cap comprises a locking portion protruding from the lower end of the inner circumference of the outer cylinder wall, which can be locked to the locking projection of the container body when the lid is closed. [Effects of the Invention]

[0009] By adopting the above configuration, the dispensing container of the present invention can be opened and closed by restricting the rotation range of the outer cap and rotating it. After opening the lid, the dispensing container is tilted so that the dispensing part faces the dispensing direction, and the operating part of the outer cap is pressed against the container body, causing the elastic deformation part to deform and a small amount of liquid to be dispensed from the dispensing part. [Brief explanation of the drawing]

[Figure 4] This figure shows the closed state of the discharge container in Embodiment 2 of the present invention, where (a) is a side cross-sectional view and (b) is a cross-sectional view of (a) taken along the YY line. [Modes for carrying out the invention]

[0011] Next, embodiments of the discharge container of the present invention will be described with reference to the drawings, using examples. In the following explanation, as seen in Figure 1(a), the vertical direction is referred to as the "axial direction," the upward direction as "up," the downward direction as "down," the left direction as the "discharge side," and the right direction as the "back side."

[0012] (Example 1) In Figure 1, A is the container body that holds the liquid contents, B is the inner cap that is attached to the mouth 4 of the container body A, and C is the outer cap that is screwed onto the outer circumference of the inner cap B, opens and closes the flow path of the liquid contents, and covers the elastically deformable part 5 of the container body A.

[0013] The container body A is composed of an upper head 1, a flange-shaped shoulder 2 that widens in diameter from the lower end of the head 1, and a bottomed body 3 that hangs down from the outer edge of the shoulder 2. The head 1 is provided at the top and includes a mouth 4 to which an inner cap B is attached, and an elastically deformable bellows-shaped elastic deformation part 5 that extends downward from the lower end of the mouth 4.

[0014] The opening 4 has a container screw projection 7 with a screw pitch α screwed onto its outer circumference. The elastically deformable portion 5 has a deformable thickness and is formed in a bellows-like shape by repeatedly expanding and contracting its diameter in a continuous manner, making it bendable and recoverable in the axial direction.

[0015] The inner cap B comprises an outer cylinder portion 10 whose inner circumference is screwed onto the outer circumference of the mouth portion 4 of the container body A; a ring-shaped upper wall portion 11 extending inward from the upper end of the inner circumference of the outer cylinder portion 10, with the upper end surface of the mouth portion 4 in close contact with its lower surface; an inner cylinder portion 12 extending vertically from the lower inner edge of the upper wall portion 11, with its outer circumference in close contact with the upper part of the inner circumference of the mouth portion 4; a cylindrical portion 13 extending upward from the upper inner edge of the upper wall portion 11; a ring-shaped partition wall 14 that closes the inside from a predetermined position on the inner circumference of the cylindrical portion 13 and has an open center; and a lower sealing cylinder 15 that is erected from the upper inner edge of the partition wall 14, with its outer circumference formed to slide against the inner circumference of the inner cylinder wall 36 of the outer cap C, which will be described later. In addition, an inclined wall 16 that rises from the inner circumference of the lower sealing cylinder 15 toward the center is continuously provided. At the center of the upper end of the inclined wall 16, a shaft portion 17 formed in a columnar shape as a plug portion protrudes. Through holes 18 serving as flow paths for the content liquid are formed in the inclined wall 16 at predetermined locations (in this embodiment, three locations at 120° intervals).

[0016] On the inner circumference of the mounting outer cylinder portion 10, an inner screw portion 20 with a screw pitch α that engages with the container screw protrusion 7 of the mouth portion 4 of the container body A is screwed. On the outer circumference of the mounting outer cylinder portion 10, an outer screw protrusion 21 is screwed with a screw pitch β larger than the screw pitch α.

[0017] As shown in FIG. 1(b), on the outer circumference of the cylindrical portion 13, rotation restricting recesses 23 cut along an arc within a predetermined angular range (in this embodiment, a 90° range) are provided opposite to each other at 180° intervals. The rotation restricting recess 23 includes closing direction end portions 23a and opening direction end portions 23b provided in the radial direction from the outer circumference, and an inner concave surface 23c recessed along an arc from both ends. Near the closing direction end portion 23a of the inner concave surface 23c, a crossing protrusion 24 having a height that allows a rotation restricting rib 43 of an outer cap C described later to cross over protrudes.

[0018] As shown in FIG. 1, the outer cap C includes a top wall portion 30 that inclines so that the discharge direction faces upward, and an outer cylinder wall 31 vertically provided from the outer edge of the lower surface of the top wall portion 30. A discharge portion 32 is formed on the discharge side of the top wall portion 30. At the tip of the discharge portion 32, a discharge port 32a is opened. A narrow discharge flow path 33 that communicates with the upper end of a central opening 30a opened at the central portion of the top wall portion 30 is opened. On the back side of the top wall portion 30, a concave operation wall portion 34 is provided as an operation portion. In addition, the top wall portion 30 has an inner wall 35 into which the cylindrical portion 13 of the inner cap B is inserted from the outer peripheral side of the lower surface, and an inner cylinder wall 36 whose inner circumference is in sliding contact with the outer circumference of the lower sealing cylinder 15, both of which are vertically provided. From the inner peripheral side of the lower surface, a sealing cylinder 37 is vertically provided from the periphery of the central opening 30a. When the lid is closed, the shaft portion 17 is inserted into the inner circumference to seal the inside.

[0019] The outer cylinder wall 31 is formed to have a height such that its lower end contacts the upper surface of the shoulder 2 of the container body A when the lid is closed. At the upper part of the inner circumference, a plurality (in this embodiment, four at 90° intervals) of lid-closing ribs 40 are provided, which contact the outer edge upper surface of the upper wall portion 11 of the inner cap B to stop lid closing when the lid is closed. Below the lid-closing ribs 40 on the inner circumference, an outer thread portion 41 with a thread pitch β that engages with the outer thread protrusion 21 of the mounting outer cylinder portion 10 of the inner cap B is screwed. In this embodiment, compared with the thread pitch α between the container thread protrusion 7 of the container body A and the inner thread portion 20 of the inner cap B, the thread pitch β between the outer thread protrusion 21 of the inner cap B and the outer thread portion 41 of the outer cap C is larger. Therefore, the rotation angle and the number of engaged steps at the same height are reduced, and the resistance becomes weaker. Compared with the thread pitch α, the resistance of the thread fitting with the thread pitch β is weaker. Therefore, when the outer cap C is rotated in the lid-opening direction with respect to the inner cap B, compared with the thread fitting of the outer cap C with respect to the inner cap B, the thread fitting of the container body A with respect to the inner cap B becomes stronger, so the inner cap B does not rotate together with the outer cap C.

[0020] On the inner circumference of the inner wall 35, as shown in Fig. 1(b), rotation-restricting ribs 43 that enter the rotation-restricting recess 23 of the cylindrical portion 13 of the inner cap B and restrict the rotation range between the lid-closing direction end portion 23a and the lid-opening direction end portion 23b, and whose inner circumferential tips rotate close to the inner concave surface 23c, project oppositely at 180° intervals. In this embodiment, when the lid is closed, the rotation-restricting rib 43 contacts the lid-closing direction end portion 23a of the inner cap B to stop the rotation of the outer cap C with respect to the inner cap B. When the lid is opened, the rotation-restricting rib 43 contacts the lid-opening direction end portion 23b of the inner cap B to stop the rotation of the outer cap C with respect to the inner cap B. Therefore, the outer cap C can only rotate within a 90° range with respect to the inner cap B and is restricted so that it can only move up and down by rotating within the thread pitch range of 90°. Furthermore, as the lid is nearing completion of closing, the rotation restricting rib 43 overcomes the overcoming projection 24 of the inner concave surface 23c, and when the lid is completely closed, the rotation restricting rib 43 fits between the overcoming projection 24 and the closing-direction end 23a, providing resistance to the opening direction and maintaining the closed state. When the outer cap C is rotated from the closed position to the open position, the rotation restricting rib 43 overcomes the overhanging protrusion 24, providing the user with a click sensation.

[0021] Next, the usage and effects of this embodiment will be described. In this embodiment, the discharge container is first positioned and placed over the inner cap B from above, then the outer cap C is rotated relative to the inner cap B in the closing direction, and the outer threaded projection 21 on the outer circumference of the mounting outer cylinder portion 10 of the inner cap B and the outer threaded portion 41 on the inner circumference of the outer cylinder wall 31 of the outer cap C are screwed together. In this case, the rotation-restricting rib 43 on the inner circumference of the inner wall 35 of the outer cap C enters into the rotation-restricting recess 23 on the outer circumference of the cylindrical portion 13 of the inner cap B and is guided within the range of the inner concave surface 23c. Finally, the rotation-restricting rib 43 of the outer cap C overcomes the overcoming projection 24 of the inner concave surface 23c of the rotation-restricting recess 23 of the inner cap B, and as shown in Figure 1(b), it comes into contact with the closing end 23a, stopping the rotation of the outer cap C relative to the inner cap B in the closing direction. At the same time, the lower end of the closing rib 40 formed on the upper inner circumference of the outer cylinder wall 31 of the outer cap C abuts against the upper outer edge surface of the upper wall portion 11 of the inner cap B, completing the setting of the inner cap B and the outer cap C.

[0022] Next, the outer cylinder portion 10 of the inner cap B, which is set on the outer cap C, is placed over the top of the container body A, which is filled with the liquid, and the inner cap B is rotated relative to the container body A in the closing direction, and the container screw projection 7 on the outer circumference of the mouth portion 4 of the top 1 and the inner screw portion 20 on the inner circumference of the outer cylinder portion 10 are screwed together, thereby attaching the inner cap B, which is set on the outer cap C, to the top of the top 1 of the container body A. At that time, the inner cylinder portion 12 of the inner cap B is inserted into the inner circumference of the mouth portion 4 of the container body A, and the inside of the container body A is sealed. In this embodiment, the inner cap B is attached by screwing the container screw projection 7 of the mouth 4 of the container body A with the inner screw portion 20 of the outer cylinder portion 10 of the inner cap B. However, the inner cap B set on the outer cap C may also be fitted into the container body A by fitting with an undercut or fitting with intermittent screws.

[0023] As shown in Figure 1(a), when the inner cap B is attached to the mouth 4 of the container body A in a closed state, the lower end of the outer cap C abuts against the upper surface of the shoulder 2 of the container body A, and the outer cylindrical wall 31 covers the elastically deformable portion 5 of the head 1. Furthermore, the outer cap C abuts against the upper surface of the shoulder portion 2 of the container body A around the entire lower end of the outer cylindrical wall 31, providing support and fixing the head portion 1 so that it does not tilt relative to the shoulder portion 2 and the body portion 3, while also holding the elastically deformable portion 5 of the head portion 1 so that it does not deform. In the closed state, the elastic deformation part 5 of the head 1 is held in place so as not to deform, thus preventing the elastic deformation part 5 from becoming worn out due to repeated deformation when not in use.

[0024] When the lid is closed, the inner circumference of the inner cylinder wall 36 of the outer cap C slides against the outer circumference of the lower sealing cylinder 15 of the inner cap B, sealing the inside of the inner cylinder wall 36. At the same time, the outer circumference of the shaft portion 17 of the inner cap B is inserted into the inner circumference of the sealing cylinder 37 of the outer cap C, sealing the flow path to the discharge passage 33 in the top wall portion 30 of the outer cap C. Furthermore, in order to prevent unauthorized opening before use, the dispensing container of this embodiment may have a shrink label or the like between the container body A and the outer cap C, although this is not shown in the illustration.

[0025] To use the liquid contents inside container body A, first grasp the outer wall 31 of the outer cap C with your fingers and rotate the outer cap C in the opening direction relative to container body A. In this embodiment, the screw engagement between the inner screw portion 20 of the inner cap B and the container screw projection 7 of the container body A is weaker than the screw engagement between the outer screw portion 41 of the outer cap C and the outer screw projection 21 of the inner cap B. Therefore, the inner cap B does not rotate together with the outer cap C when it rotates in the opening direction.

[0026] When the outer cap C is rotated in the opening direction relative to the container body A and inner cap B, the outer cap C unscrews off the inner cap B, and the rotation-restricting rib 43 of the outer cap C rotates in the opening direction. The rotation-restricting rib 43 overcomes the overcoming projection 24 of the inner concave surface 23c of the rotation-restricting recess 23 on the outer circumference of the cylindrical portion 13 of the inner cap B, allowing the user to feel a click. Furthermore, when the outer cap C is rotated, the rotation restricting rib 43 is guided within the range of the inner concave surface 23c of the rotation restricting recess 23, and finally, as shown in Figure 2(b), the rotation restricting rib 43 comes into contact with the end 23b in the opening direction, stopping the rotation of the outer cap C. In this embodiment, since the rotation-restricting recess 23 is recessed within a 90° range, the rotation-restricting ribs 43 that abut both ends can only rotate within a 90° range, and the rotation of the outer cap C is stopped within a 90° range from the closed state to the open state, and its upward movement is also restricted by the rotation amount of the screw pitch β, thereby preventing the screw from coming loose due to excessive rotation, preventing the outer cap C from coming off the inner cap B, and preventing the sliding contact between the inner circumference of the inner cylinder wall 36 of the outer cap C and the outer circumference of the lower sealing cylinder 15 of the inner cap B from being lost.

[0027] When the rotation of the outer cap C relative to the inner cap B is stopped, as shown in Figure 2, the outer cap C rises relative to the inner cap B and the container body A, and temporarily stops in an open position. When the outer cap C rises, the inner circumference of the inner cylinder wall 36 of the outer cap C and the outer circumference of the lower sealing cylinder 15 of the inner cap B slide into contact, maintaining the seal inside the inner cylinder wall 36. At the same time, the outer circumference of the shaft portion 17 of the inner cap B disengages from the inner circumference of the sealing cylinder 37 of the outer cap C, releasing the seal. This opens the flow path to the discharge flow path 33 inside the top wall portion 30 of the outer cap C, and creates an open state where the flow path from inside the lower sealing cylinder 15 of the inner cap B to the discharge portion 32 of the outer cap C is in communication. Furthermore, the outer cap C rises, the lower end of the outer cylinder wall 31 separates from the upper surface of the shoulder portion 2 of the container body A, the fixing of the elastic deformation portion 5 of the head portion 1 of the container body A is released, and the elastic deformation portion 5 of the container body A becomes deformable due to the gap formed between them.

[0028] As shown in Figure 3, when the open-lid discharge container is tilted so that the discharge port 32a of the discharge section 32 of the outer cap C faces downward, the liquid contents inside the container body A enter the inner circumference of the lower sealing cylinder 15 in the center of the partition wall 14 of the inner cap B, then flow from the inner surface of the inclined wall 16 through the flow hole 18 into the inner cylinder wall 36 of the outer cap C, and are guided from the inner circumference of the sealing cylinder 37 to the discharge channel 33 of the top wall section 30. As the liquid contents are guided into the narrow-mouthed discharge channel 33 and flow towards the discharge section 32, the discharge opening 32a is blocked by the surface tension of the liquid contents near the discharge opening 32a.

[0029] When the operating wall portion 34 of the outer cap C is pressed while the discharge port 32a is blocked with the liquid contents, the mouth portion 4 of the container body A to which the inner cap B is attached bends and deforms relative to the shoulder portion 2 and body portion 3 so that the elastic deformation portion 5 is tilted in the axial direction. As the elastic deformation section 5 deforms (the outer cap C and inner cap B tilt along the elastic deformation section 5), the liquid inside the container body A is pressurized, and the pressurized liquid flows through the discharge channel 33 and is discharged in small quantities from the discharge port 32a.

[0030] Once the liquid contents have been dispensed and the pressure on the operating wall portion 34 of the outer cap C is released, the elastic deformation portion 5 returns to its original shape due to its restoring force, creating negative pressure inside the container body A and drawing the liquid contents back in. As a result, outside air is drawn inward through the discharge channel 33 along with the liquid contents from the discharge port 32a, relieving the negative pressure and returning the liquid contents of the container body A to their original state. By pressing the operating wall portion 34 of the outer cap C again, the liquid contents inside the container body A can be dispensed by dripping from the discharge port 32a, allowing for repeated use.

[0031] After dispensing, the contents are pulled back into the inner cap B by the return of the elastically deformable part 5 of the container body A. As a result, no contents remain in the narrow dispensing channel 33, preventing them from drying out and blocking the dispensing channel 33, and preventing bacteria from growing in any remaining contents. Therefore, the container can be used hygienically as a dispensing container.

[0032] Once the liquid contents have been used up, the dispensing container is returned to its upright position as shown in Figure 2, the outer cap C is rotated in the closing direction relative to the inner cap B, and finally, as shown in Figure 1, the rotation restricting rib 43 of the outer cap C is brought into contact with the closing-direction end 23a of the rotation restricting recess 23 of the inner cap B to close it, and the outer circumference of the shaft portion 17 of the inner cap B is inserted into the inner circumference of the sealing cylinder 37 of the outer cap C to seal it, thereby blocking the flow path to the dispensing channel 33 in the top wall portion 30 of the outer cap C.

[0033] Once all the liquid inside container body A has been used, as shown in Figure 2, the outer cap C is in an open state where its rotation is stopped by contact between the rotation-restricting rib 43 and the opening-direction end 23b of the rotation-restricting recess 23 relative to the inner cap B. If the outer cap C is rotated more forcefully relative to container body A, the inner cap B will rotate together with the outer cap C relative to the head 1 of container body A, and the outer cap C and inner cap B can be removed from container body A.

[0034] (Example 2) Next, Example 2, which modifies the configuration of the container body A and outer cap C in Example 1, will be described with reference to the figures. In the following description, components identical to those in Example 1 will be denoted by the same reference numerals, and modified components will be denoted by new reference numerals, with the differences being the main focus of the explanation.

[0035] In Figure 4, Aa is the container body that holds the liquid contents, B is the inner cap attached to the mouth 4 of the container body Aa, and Ca is the outer cap that is screwed onto the outer circumference of the inner cap B, opens and closes the flow path of the liquid contents, and covers the elastically deformable part 5 of the container body Aa.

[0036] The container body Aa is composed of an upper head 50, a flange-shaped shoulder 2 that widens in diameter from the lower end of the head 50, and a bottomed body 3 that hangs down from the outer edge of the shoulder 2. The head 50 is provided at the top and includes a mouth 4 to which an inner cap B is attached, an elastic deformation part 5 that extends downward from the lower end of the mouth 4 and is formed in a bellows shape that can be elastically deformed, and a downward-preventing part 51 that hangs down from the lower end of the elastic deformation part 5.

[0037] Locking projections 53 are provided at predetermined locations (in this embodiment, two locations at 180° intervals) on the upper outer circumference of the lowering prevention section 51.

[0038] The outer cap Ca comprises a top wall portion 30 and an outer cylindrical wall 60 that extends vertically from the lower outer edge of the top wall portion 30.

[0039] The outer cylindrical wall 60 is formed to a height such that its lower end abuts against the upper surface of the shoulder portion 2 of the container body Aa when the lid is closed. Multiple closing ribs 40 are provided on the upper part of the inner circumference, the lower end of which abuts against the upper surface of the outer edge of the upper wall portion 11 of the inner cap B when the lid is closed to stop the lid from closing. Below the closing ribs 40 on the inner circumference, an outer threaded portion 41 is provided that screws into the outer threaded projection 21 of the outer cylindrical portion 10 on which the inner cap B is attached. As shown in Figure 4(b), a locking portion 62 is provided at the lower end of the inner circumference, the upper part of which abuts against the lower part of the locking projection 53 of the lowering prevention portion 51 of the container body Aa when the lid is closed to lock it in place, and which disengages from the locking projection 53 when the lid is not closed.

[0040] Next, the usage and effects of this embodiment will be described. As shown in Figure 4, in this embodiment, when the lid is closed, the upper part of the locking portion 62 of the outer cylindrical wall 60 of the outer cap Ca catches and engages with the lower part of the locking projection 53 of the downward prevention portion 51 of the container body Aa, thereby locking the lower end of the outer cylindrical wall 60 of the outer cap Ca so that the part of the top 50 of the container body Aa below the downward prevention portion 51 does not come off downwards. Therefore, even if the body portion 3 of the container body Aa is pulled while the lid is closed, the downward-preventing portion 51 of the container body Aa does not detach from the lower end of the outer cylindrical wall 60 of the outer cap Ca. Along with the contact between the lower end of the outer cylindrical wall 60 of the outer cap Ca and the upper surface of the shoulder portion 2 of the container body Aa, the elastic deformation portion 5 of the head portion 50 is held in place without deformation. This prevents the elastic deformation portion 5 from becoming worn out due to repeated deformation when not in use.

[0041] Furthermore, when the outer cap Ca is rotated from the closed position to the open position relative to the container body Aa and inner cap B, the engagement between the locking portion 62 of the outer cap Ca and the locking projection 53 of the container body Aa is released. As the outer cap Ca rises due to rotation in the opening direction, a gap is formed between the lower end of the outer cylinder wall 60 and the upper surface of the shoulder portion 2 of the container body Aa, allowing the elastically deformable portion 5 of the container body Aa to deform. Other effects and benefits are the same as in Example 1. [Industrial applicability]

[0042] The dispensing container of the present invention can be opened and closed by restricting the rotation range of the outer cap and rotating it. After opening the lid, the dispensing container is tilted so that the dispensing part faces the dispensing direction, and the operating part of the outer cap is pressed against the container body, causing the elastic deformation part to deform and allowing a small amount of liquid to be dispensed from the dispensing part, thus providing good operability. Furthermore, it is also possible to dispense the liquid by squeezing the container body, making it suitable as a dispensing container that can dispense small amounts of various cosmetics, pharmaceuticals, and seasonings as the liquid contents.
