Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional syringe container, different types of content liquids discharged from the pair of discharge holes may be mixed unintentionally, and there is a risk, for example, that the start of solidification may be accelerated. During storage after dispensing the liquid contents, some of the liquid contents that adhered to the opening periphery of the discharge hole in the nozzle member during dispensing may adhere to the cap. In this case, when the cap is attached to at least one of the cylinder and nozzle member after dispensing the liquid contents again, if the cap is reversed, for example, there is a risk that the liquid contents that adhered to the cap from the opening periphery of one discharge hole in the nozzle member during storage may come into contact with the liquid contents that adhered to the opening periphery of the other discharge hole in the nozzle member during dispensing.

[0005] The present invention provides a syringe container that can prevent unintended mixing of different liquid contents dispensed from a pair of discharge holes. [Means for solving the problem]

[0006] A syringe container according to one aspect of the present invention includes a pair of cylinders extending vertically and connected in the left-right direction of the transverse direction intersecting the vertical direction, a pair of plungers extending vertically and separately fitted into the pair of cylinders so as to be slidable vertically, a pair of mounting cylinders provided at the upper end of each of the pair of cylinders and projecting forward in the direction perpendicular to the left-right direction of the transverse direction, and the inside of the pair of mounting cylinders communicating separately into the pair of cylinders, a fitting cylinder separately fitted into the pair of mounting cylinders so as to be rotatable around the central axis of the mounting cylinder, and extending from the front end of the fitting cylinder in a direction intersecting the front-rear direction, The device comprises a pair of nozzle cylinder members, each having a nozzle cylinder whose tip opening is a discharge hole from which the liquid contents are discharged. Each of the pair of nozzle cylinder members has a regulating portion formed thereon that, when the nozzle cylinder is in an upright position, locks onto the other nozzle cylinder member or the mounting member, restricting the discharge hole from facing inward towards the other nozzle cylinder side in the left-right direction. A communication opening is formed in the fitting cylinder, and the nozzle cylinder members are rotatable around the central axis between a discharge position in which the inside of the cylinder and the discharge hole communicate through the communication opening, and a standby position in which communication between the inside of the cylinder and the discharge hole through the communication opening is blocked.

[0007] According to one aspect of the present invention, each of the pair of nozzle cylinder members has a regulating portion that, when the nozzle cylinder is in a position extending vertically, locks onto the other nozzle cylinder member or mounting member, restricting the discharge hole from facing inward towards the other nozzle cylinder side in the left-right direction. This prevents the liquid contents discharged from one discharge hole from going towards the discharge hole side of the other nozzle cylinder, thereby suppressing unintentional mixing of the liquid contents discharged from one discharge hole and the liquid contents discharged from the other discharge hole. A communication opening is formed in the fitting cylinder, and the nozzle cylinder member is rotatable around the central axis between a discharge position in which the inside of the cylinder and the discharge hole communicate through the communication opening, and a standby position in which communication between the inside of the cylinder and the discharge hole through the communication opening is blocked. Therefore, when the nozzle cylinder member is in the standby position, the outside and the inside of the cylinder do not communicate through the discharge hole, the communication opening, and the inside of the mounting cylinder, making it possible to eliminate the need for a cap to cover the discharge hole, and preventing unintended mixing of the contents discharged from one discharge hole and the contents discharged from the other discharge hole due to the contents discharged from the discharge hole and adhering to the cap. Therefore, it is possible to prevent unintentional mixing of different liquid contents discharged from a pair of discharge holes.

[0008] When the nozzle cylinder member is in the discharge position, the discharge hole may face upward, and when the nozzle cylinder member is in the standby position, the discharge hole may face downward.

[0009] When the nozzle cylinder is in the discharge position, the discharge hole faces upward, in the direction the plunger is pushed in, making it easier to discharge the liquid contents to the desired position. When the nozzle cylinder member is in the standby position, the discharge hole faces downwards, allowing the user to visually confirm that the syringe container is in storage condition, thus preventing accidental operation.

[0010] The fitting cylinder comprises an inner cylinder fitted into the mounting cylinder and an outer cylinder mounted on the mounting cylinder, the communication opening may be formed in the inner cylinder and the restricting portion may be formed in the outer cylinder.

[0011] The fitting cylinder comprises an inner cylinder fitted into the mounting cylinder and an outer cylinder mounted on the mounting cylinder. A communication opening is formed in the inner cylinder, and a regulating portion is formed in the outer cylinder. This allows for a simple configuration with reduced bulk, while preventing unintended mixing of the liquid contents discharged from one discharge hole and the liquid contents discharged from the other discharge hole. [Effects of the Invention]

[0012] According to the above embodiment of the present invention, it is possible to prevent unintentional mixing of different liquid contents discharged from a pair of discharge holes. [Brief explanation of the drawing]

[Figure 2] This is a semi-vertical cross-sectional view of a syringe container (dispensing position) of one embodiment, viewed from the front. [Figure 3] This is a cross-sectional view taken along the line III-III in Figure 2. [Figure 4] This is a view along the line IV-IV in Figure 2. [Modes for carrying out the invention]

[0014] An embodiment of the present invention will be described below with reference to the drawings. As shown in Figures 1 to 4, the syringe container 1 of this embodiment comprises a pair of cylinders 11, a pair of plungers 12, a mounting member 13, and a pair of nozzle cylinder members 14.

[0015] A pair of cylinders 11 extend in the vertical direction Z and are connected in the left-right direction X, which is a lateral direction intersecting the vertical direction Z. The cylinder 11 is formed in a toped cylindrical shape. On the top wall 21 of each cylinder 11, a connecting cylinder 22 protruding upward is provided separately. The inside of the connecting cylinder 22 communicates with the inside of the cylinder 11. The central axis O2 of the connecting cylinder 22 is on the inner side, which is the side of the other cylinder 11 in the left-right direction X, with respect to the central axis O1 of the cylinder 11, and is located at the same position in the front-back direction Y, which is orthogonal to the left-right direction X, among the lateral directions.

[0016] A pair of plungers 12 extend in the vertical direction Z and are slidably fitted in the vertical direction Z separately within the pair of cylinders 11. The lower end portions of the pair of plungers 12 protrude downward from within the cylinder 11. The lower end portions of the pair of plungers 12 are connected in the left-right direction X. The plunger 12 is disposed coaxially with the cylinder 11.

[0017] The mounting member 13 is provided at the upper end portion of each of the pair of cylinders 11. The mounting member 13 includes a pair of base cylinder portions 26 and a pair of mounting cylinders 27.

[0018] The pair of base cylinder portions 26 extend in the vertical direction Z and are hermetically fitted to the connecting cylinders 22 of the pair of cylinders 11 separately. The base cylinder portion 26 is formed in a cylindrical shape and is disposed coaxially with the central axis O2 of the connecting cylinder 22. The pair of mounting cylinders 27 protrude forward separately from the pair of base cylinder portions 26 and are formed in a cylindrical shape. The inside of the mounting cylinder 27 communicates with the inside of the base cylinder portion 26 and communicates with the inside of the cylinder 11 through the inside of the connecting cylinder 22. The inner diameters of the mounting cylinder 27 and the base cylinder portion 26 are equal to each other. The central axis O3 of the mounting cylinder 27 is located inside the central axis O1 of the cylinder 11 in the left-right direction X and outside the central axis O2 of the connecting cylinder 22 in the left-right direction X.

[0019] The pair of nozzle cylinder members 14 includes a fitting cylinder 23 and a nozzle cylinder 24.

[0020] The fitting cylinder 23 is formed in a cylindrical shape extending in the front-rear direction Y, and is respectively fitted rotatably around the central axis O3 to a pair of mounting cylinders 27. The fitting cylinder 23 is formed in a double-cylindrical shape including an inner cylinder 31 fitted inside the mounting cylinder 27 and an outer cylinder 32 externally mounted on the mounting cylinder 27. At the front end portions located in front of the mounting cylinder 27 in each of the inner cylinder 31 and the outer cylinder 32, they are connected at a plurality of positions spaced apart around the central axis O3 of the mounting cylinder 27.

[0021] The inner peripheral surface of the outer cylinder 32 is undercut-fitted to the outer peripheral surface of the mounting cylinder 27 in a state where forward movement is restricted. A part of the inner cylinder 31 around the central axis O3 is cut out, and a communication opening 23a opening into the inner cylinder 31 is formed. The communication opening 23a is formed at the rear end portion of the inner cylinder 31 and opens at the rear end opening edge of the inner cylinder 31. As shown in FIGS. 1 and 2, the communication opening 23a is formed in the inner cylinder 31 over an angular range of about 90° centered on the central axis O3.

[0022] The nozzle cylinder 24 extends from the front end portion of the fitting cylinder 23 in a direction intersecting the front-rear direction Y, and the tip opening is a discharge hole 15 through which the content liquid is discharged. The central axis O4 of the nozzle cylinder 24 is orthogonal to the central axis O3 of the mounting cylinder 27. The nozzle cylinder 24 is located in front of the mounting cylinder 27. As shown in FIGS. 2 and 3, in a state where the nozzle cylinder 24 extends straight upward from the front end portion of the fitting cylinder 23, the communication opening 23a faces obliquely downward toward the inside in the left-right direction X when viewed from the front, and opens into the base cylinder portion 26 over the entire area around the central axis O3.

[0023] The pair of nozzle cylinder members 14 are respectively provided rotatably around the central axis O3 of the mounting cylinder 27 between a discharge position where the cylinder 11 communicates with the discharge hole 15 through the communication opening 23a and a standby position where the communication between the cylinder 11 and the discharge hole 15 through the communication opening 23a is blocked. When the nozzle cylinder member 14 is in the discharge position, the discharge hole 15 faces upward, and when the nozzle cylinder member 14 is in the standby position, the discharge hole 15 faces downward.

[0024] Each of the pair of nozzle cylinder members 14 has a first restricting portion (restricting portion) 25 formed therein, which locks to the other nozzle cylinder member 14 when the nozzle cylinder 24 is in an orientation extending in the vertical direction Z, and restricts the discharge hole 15 from facing inward in the left-right direction X. In this case, the pair of nozzle cylinders 24 do not necessarily have to have a symmetrical shape with respect to a straight line extending in the vertical direction Z when viewed from the front-to-back direction Y.

[0025] The first restricting portion 25 is formed on the outer cylinder 32 of the fitting cylinder 23. The first restricting portion 25 has a triangular shape when viewed from the front. Of the three sides forming this triangle, two sides are tangent portions that are circumscribing the outer surface of the outer cylinder 32, and the remaining side is part of the outer surface of the outer cylinder 32. The first restricting portion 25 is formed over the entire area in the front-rear direction on the outer surface of the outer cylinder 32.

[0026] When both of the pair of nozzle cylinders 24 are in a position where they extend straight in the vertical direction Z, the aforementioned tangential portions of each of the pair of first restricting portions 25 abut against each other in the left-right direction X, thereby restricting the discharge hole 15 from facing inward in the left-right direction X. If only one of the pair of nozzle cylinders 24 is positioned to extend straight in the vertical direction Z, the first restricting portion 25 of one nozzle cylinder member 14 will come into contact with the outer circumferential surface of the outer cylinder 32 of the other nozzle cylinder member 14, thereby restricting the discharge hole 15 of one nozzle cylinder 24 from facing inward in the left-right direction X.

[0027] Each of the pair of nozzle cylinder members 14 has a second restricting portion (restricting portion) 33 formed therein, which locks onto the mounting member 13 when the nozzle cylinder 24 is in an orientation extending in the vertical direction Z, and restricts the discharge hole 15 from facing inward in the left-right direction X. The second restricting portion 33 is formed on the outer cylinder 32 of the fitting cylinder 23. The second restricting portion 33 protrudes rearward from the rear end opening edge of the outer cylinder 32. A locking surface 34 facing outward in the left-right direction X is formed on the upper end of the mounting member 13. A pair of locking surfaces 34 are provided, one on the left and one on the right. When the pair of nozzle cylinders 24 are in a position where they extend in the up-down direction Z, the pair of second restricting parts 33 will contact the pair of locking surfaces 34 individually. Note that either the first restricting portion 25 or the second restricting portion 33 may be omitted. The mounting member 13 may be provided with a surface that the second restricting portion 33 contacts when the nozzle cylinder member 14 is in the standby position.

[0028] As described above, in the syringe container 1 according to this embodiment, each of the pair of nozzle cylinder members 14 has a first restricting portion 25 that locks to the other nozzle cylinder member 14 when the nozzle cylinder 24 is in a position extending in the vertical direction Z, restricting the discharge hole 15 from facing inward in the left-right direction X. This makes it possible to prevent the liquid contents discharged from the discharge hole 15 from going towards the discharge hole 15 side of the other nozzle cylinder 24, thereby suppressing unintentional mixing of the liquid contents discharged from one discharge hole 15 and the liquid contents discharged from the other discharge hole 15.

[0029] A communication opening 23a is formed in the fitting cylinder 23, and the nozzle cylinder member 14 is rotatable around the central axis O3 of the mounting cylinder 27 between a discharge position in which the inside of the cylinder 11 and the discharge hole 15 communicate through the communication opening 23a, and a standby position in which communication between the inside of the cylinder 11 and the discharge hole 15 through the communication opening 23a is blocked. Therefore, when the nozzle cylinder member 14 is in the standby position, the outside and the inside of the cylinder 11 do not communicate through the discharge hole 15, the communication opening 23a, and the inside of the mounting cylinder 27, making it possible to eliminate the need for a cap to cover the discharge hole 15, and preventing unintended mixing of the contents discharged from one discharge hole 15 and the contents discharged from the other discharge hole 15 due to the contents discharged from the discharge hole 15 adhering to the cap.

[0030] Therefore, it is possible to prevent unintentional mixing of different liquid contents discharged from the pair of discharge holes 15.

[0031] When the nozzle cylinder member 14 is in the discharge position, the discharge hole 15 faces upward, which is the direction in which the plunger 12 is pushed, making it easier to discharge the liquid contents to the desired position. When the nozzle cylinder member 14 is in the standby position, the discharge hole 15 faces downward, allowing the user to visually confirm that the syringe container 1 is in storage condition, thereby preventing accidental operation.

[0032] The fitting cylinder 23 comprises an inner cylinder 31 fitted into the mounting cylinder 27 and an outer cylinder 32 mounted on the mounting cylinder 27. A communication opening 23a is formed in the inner cylinder 31, and a first regulating portion 25 is formed in the outer cylinder 32. This allows for a simple configuration with reduced bulk, while preventing unintended mixing of the liquid contents discharged from one discharge hole 15 and the liquid contents discharged from the other discharge hole 15.

[0033] Furthermore, the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.

[0034] For example, when the nozzle cylinder member 14 is in the discharge position, the discharge hole 15 may face downward or outward in the left-right direction X, and when the nozzle cylinder member 14 is in the standby position, the discharge hole 15 may face upward or outward in the left-right direction X. The fitting cylinder 23 does not necessarily have an outer cylinder 32, and the first regulating portion 25 may be formed, for example, on the nozzle cylinder 24.

[0035] In a configuration where the discharge hole 15 faces upward when the nozzle cylinder member 14 is in the discharge position, notches may be formed at the tips of the pair of nozzle cylinders 24 so as to open outwards in the left-right direction X, thereby opening the discharge hole 15. In this case, when the liquid contents are discharged from one discharge port 15, the liquid contents are discharged in a direction away from the other discharge port 15. For example, when the liquid contents are discharged with a pair of discharge ports 15 in contact with or close to the surface to be discharged, it is possible to reliably prevent the liquid contents discharged from one discharge port 15 from unintentionally mixing with the liquid contents discharged from the other discharge port 15.

[0036] When the pair of nozzle cylinders 24 are in an expanded position of approximately 0° to 90° when viewed from the front-to-back direction, a configuration may be adopted in which at least one of the first restricting part 25 and the second restricting part 33 prevents the nozzle cylinders 24 from moving any further inward in the left-to-right direction X.

[0037] Furthermore, without departing from the spirit of the present invention, the components in the above embodiments may be replaced with well-known components as appropriate, and the above embodiments and modifications may be combined as appropriate. [Explanation of symbols]
