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 unintentionally mixed, 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 unintentional mixing of different liquid contents discharged from a pair of discharge holes, and prevents incorrect relative positioning of the cap, cylinder, and nozzle member when attaching the cap to at least one of the cylinder and nozzle member. [Means for solving the problem]

[0006] A syringe container according to one aspect of the present invention comprises: 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 fitted separately within the pair of cylinders so as to be slidable vertically; a nozzle member provided at the upper end of each of the pair of cylinders, having a pair of discharge holes that communicate separately within the pair of cylinders; and a cap detachably attached to at least one of the cylinders and the nozzle member, covering the pair of discharge holes, wherein the nozzle member is connected in the left-right direction of the transverse direction. The cylinder comprises a pair of nozzle cylinders projecting forward perpendicular to the cylinder, the inside of each nozzle cylinder serving as the discharge hole, and the front ends of the pair of nozzle cylinders are formed with notches that open outwards, on the opposite side of the other nozzle cylinder in the left-right direction, so as to the discharge hole. The cap is formed in a top-shaped cylindrical form having a top wall that covers the upper end of the nozzle cylinder and a circumferential wall, the circumferential wall opening the nozzle member to the rear and covering the front end opening of the discharge hole, and the cap is attached to and detached from at least one of the cylinder and the nozzle member by sliding it in the front-rear direction.

[0007] According to one aspect of the present invention, a syringe container is formed at the front end of a pair of nozzle cylinders, with notches cut out so that the discharge holes open outwards in the left-right direction. Therefore, when the liquid contents are discharged from one discharge hole, they are discharged away from the other discharge hole. For example, when the liquid contents are discharged with the pair of discharge holes in contact with or close to the surface to be discharged, it is possible to suppress the unintentional mixing of the liquid contents discharged from one discharge hole and the liquid contents discharged from the other discharge hole.

[0008] Since the cap is formed in a top-shaped cylindrical form with a top wall that covers the upper end of the nozzle cylinder, it becomes impossible to attach the cap to the cylinder and nozzle member when it is upside down. The peripheral wall of the cap, which is formed in a top-cylindrical shape, opens the nozzle member to the rear and covers the front end opening of the discharge hole. As a result, the cap slides in the front-rear direction, allowing it to be attached to and detached from at least one of the cylinder and the nozzle member. This makes it easy and reliable to align the relative positions of the cap, the cylinder and the nozzle member around the vertical axis. Therefore, when attaching the cap to at least one of the cylinder and the nozzle member, it is possible to prevent errors in the relative positioning of the cap, the cylinder and the nozzle member.

[0009] The notch may be designed so that, when viewed from the front, the discharge hole is opened diagonally upward, facing outward in the left-right direction.

[0010] Because the notch is designed so that the discharge hole, when viewed from the front, opens diagonally upward and outward in the left-right direction, the discharge hole faces not only forward but also upward, in the direction in which the plunger is pushed. For example, when discharging liquid contents by bringing a pair of discharge holes into contact with or close to the surface to be discharged, it becomes easier to discharge the contents to the desired position while ensuring that the liquid is discharged away from the other discharge hole.

[0011] A pair of cylinders may have locking projections that protrude outward in the left-right direction, and the cap may be provided with a locking portion that protrudes outward in the left-right direction and extends in the front-rear direction, with its rear end contacting or approaching the locking projection from behind, and the locking portion may be elastically displaceable to the cap so that its rear end moves in the left-right direction.

[0012] Since the pair of cylinders have locking protrusions that project outward in the left-right direction, and the cap is provided with a locking portion that projects outward in the left-right direction and extends in the front-rear direction, with its rear end contacting or approaching the locking protrusion from behind, the forward movement of the cap relative to the cylinder is restricted, and the cap can be stably attached to the cylinder. Since the locking portion is elastically displaceable to the cap so that its rear end moves in the left-right direction, elastically displacing the locking portion so that its rear end moves outward in the left-right direction allows the rear end of the locking portion to be separated from the locking projection of the cylinder, thereby allowing the cap to be moved forward relative to the cylinder and detached from the cylinder and nozzle member. [Effects of the Invention]

[0013] According to the above embodiment of the present invention, it is possible to prevent unintentional mixing of different liquid contents discharged separately from a pair of discharge holes, and to prevent incorrect relative positioning of the cap, cylinder and nozzle member when attaching the cap to at least one of the cylinder and nozzle member. [Brief explanation of the drawing]

[0014] [Figure 1] This is a view of a syringe container according to one embodiment, seen from the front. [Figure 2] This is a view taken along the line II-II in Figure 1. [Figure 3] This is a cross-sectional view taken along the line III-III in Figure 2. [Modes for carrying out the invention]

[0015] An embodiment of the present invention will be described below with reference to the drawings. As shown in Figures 1 to 3, the syringe container 1 of this embodiment comprises a pair of cylinders 11, a pair of plungers 12, a nozzle member 13, and a cap 14.

[0016] 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 cylinders 11 are formed in a top - closed 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 on 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 - rear direction Y, which is perpendicular to the left - right direction X, among the lateral directions.

[0017] A first locking protrusion 24 and a second locking protrusion 25 are formed on the pair of cylinders 11. The first locking protrusion 24 and the second locking protrusion 25 are provided at the upper end of the cylinder 11. The first locking protrusion 24 protrudes outward in the left - right direction X from the outer peripheral surface of the cylinder 11. The first locking protrusion 24 is formed in a plate shape with the front and back surfaces facing the front - rear direction Y. The second locking protrusion 25 protrudes forward from the outer peripheral surface of the cylinder 11. The second locking protrusion 25 is formed in a plate shape with the front and back surfaces facing the vertical direction Z. The second locking protrusion 25 is located below the upper end of the first locking protrusion 24 and above the lower end of the first locking protrusion 24.

[0018] A pair of plungers 12 extend in the vertical direction Z and are slidably fitted in the pair of cylinders 11 in the vertical direction Z respectively. The lower ends of the pair of plungers 12 protrude downward from the inside of the cylinder 11. The lower ends of the pair of plungers 12 are connected in the left - right direction X. The plungers 12 are arranged coaxially with the cylinders 11.

[0019] The nozzle member 13 is provided at the upper end of each of the pair of cylinders 11, and a pair of discharge holes 15 that communicate separately with the inside of the pair of cylinders 11 are formed. The nozzle member 13 is formed in a toped cylindrical shape and is fitted to the connecting cylinder 22 of the cylinder 11 in a liquid-tight manner. The nozzle member 13 includes a nozzle cylinder 23 that protrudes forward, and the inside of the nozzle cylinder 23 is the discharge hole 15. The discharge hole 15 opens forward. The discharge hole 15 communicates with the inside of the cylinder 11 through the inside of the connecting cylinder 22. The positions of the central axis of the discharge hole 15 and the central axis O2 of the connecting cylinder 22 in the left-right direction X coincide with each other.

[0020] At the front end of the pair of nozzle cylinders 23, a notch portion 23a is formed so that the discharge hole 15 opens toward the outside, which is the opposite side of the other nozzle cylinder 23 side in the left-right direction X. The notch portion 23a opens integrally with the outer peripheral surface of the nozzle cylinder 23 and the front end opening edge of the nozzle cylinder 23. When viewed from the front, the notch portion 23a opens the discharge hole 15 obliquely upward facing the outside in the left-right direction X. When viewed from the front, the size of the notch portion 23a in the hole circumferential direction along the central axis of the discharge hole 15 is the same as the inner diameter of the discharge hole 15.

[0021] The cap 14 is detachably attached to at least one of the cylinder 11 and the nozzle member 13 and covers the pair of discharge holes 15. The cap 14 is formed in a toped cylindrical shape having a top wall 14a that covers the upper end of the nozzle cylinder 23 and a peripheral wall 14b. The peripheral wall 14b opens the nozzle member 13 to the rear and covers the front end opening of the discharge hole 15. The peripheral wall 14b呈現出a C-shaped, U-shaped, or C-shaped opening facing rearward in a cross-sectional view orthogonal to the vertical direction Z. That is, the peripheral wall 14b has a front wall located at the front end and facing the front-rear direction, and a pair of left and right side walls, and does not have a bottom wall located at the lower end and facing the vertical direction, and a rear wall located at the rear end and facing the front-rear direction. The cap 14 is detached from at least one of the cylinder 11 and the nozzle member 13 by sliding in the front-rear direction Y. It should be noted that there is an unclear part in the original text "周壁14bは、上下方向Zに直交する横断面視で、後方に向けて開口するC字状、U字状、若しくはコ字状を呈する。すなわち、周壁14bは、前端に位置して前後方向を向く前壁と、左右一対の側壁と、を有し、下端に位置して上下方向を向く底壁、および後端に位置して前後方向を向く後壁は有していない。" The translated text "The peripheral wall 14b呈現出a C-shaped, U-shaped, or C-shaped opening facing rearward in a cross-sectional view orthogonal to the vertical direction Z. That is, the peripheral wall 14b has a front wall located at the front end and facing the front-rear direction, and a pair of left and right side walls, and does not have a bottom wall located at the lower end and facing the vertical direction, and a rear wall located at the rear end and facing the front-rear direction." is a rough translation based on the understanding of the context, and the original text may need to be further clarified for a more accurate translation.As shown in Figure 3, the portion of the peripheral wall 14b of the cap 14 located at the front end and facing in the front-rear direction Y has a pair of upper and lower support portions 14c formed thereon, which protrude toward the rear and sandwich the second locking projection 25 of the cylinder 11 in the vertical direction Z.

[0022] As shown in Figure 2, the cap 14 is provided with a locking portion 26 that protrudes outward in the left-right direction X and extends in the front-rear direction Y, with its rear end contacting or approaching the first locking projection 24 of the cylinder 11 from behind the first locking projection 24. The locking portion 26 is elastically displaceable to the cap 14 so that its rear end can move in the left-right direction X.

[0023] The locking portion 26 comprises a first plate portion 26a that protrudes outward in the left-right direction X from portions of the peripheral wall 14b of the cap 14 that face each other in the left-right direction X, and a second plate portion 26b that protrudes from the first plate portion 26a in both the front-rear direction Y.

[0024] The front and back surfaces of the first plate portion 26a are oriented in the front-to-back direction Y. The first plate portion 26a has a rectangular shape that is elongated in the up-to-down direction Z when viewed from the front-to-back direction Y. The front and back surfaces of the second plate portion 26b are oriented in the left-right direction X. The second plate portion 26b has a rectangular shape that is elongated in the front-rear direction Y when viewed from the left-right direction X. The front end of the second plate portion 26b is located in front of the peripheral wall 14b of the cap 14. The second plate portion 26b is rotatably mounted in the left-right direction X around the connection portion with the first plate portion 26a. As a result, the locking portion 26 is elastically displaceable connected to the peripheral wall 14b of the cap 14 via the first plate portion 26a so that both ends of the second plate portion 26b in the front-rear direction Y move in the left-right direction X.

[0025] A projection 26c is formed at the rear end of the second plate portion 26b, projecting inward in the left-right direction X, and contacting or approaching the first locking projection 24 of the cylinder 11 from behind the first locking projection 24. The projection 26c has a locking plane facing forward and contacting or approaching the rear surface of the first locking projection 24, and an inclined surface that extends outward in the left-right direction X from the inner end of the locking plane in the left-right direction X towards the rear.

[0026] When the front end of the second plate portion 26b is pushed inward in the left-right direction X, the projection 26c of the second plate portion 26b is displaced outward in the left-right direction X, moving away from the first locking projection 24 of the cylinder 11 outward in the left-right direction X. As a result, the cap 14 becomes movable forward relative to the nozzle member 13.

[0027] When the cap 14 is attached to the nozzle member 13 and cylinder 11, as the cap 14 is moved backward toward the nozzle member 13 and cylinder 11, the inclined surface of the projection 26c of the second plate portion 26b slides against the first locking projection 24 of the cylinder 11, and the second plate portion 26b rotates in the left-right direction X around the connection portion with the first plate portion 26a, causing the projection 26c to displace outward in the left-right direction X and move over the first locking projection 24 to the rear. At this time, the second plate portion 26b returns to its original position around the connection portion with the first plate portion 26a, and the locking plane of the projection 26c comes into contact with or close to the rear surface of the first locking projection 24.

[0028] As described above, in the syringe container 1 according to this embodiment, a notch 23a is formed at the front end of the pair of nozzle cylinders 23, so that the discharge holes 15 open outwards in the left-right direction X. Therefore, when the liquid contents are discharged from one discharge hole 15, they are discharged away from the other discharge hole 15. For example, when the liquid contents are discharged with the pair of discharge holes 15 in contact with or close to the surface to be discharged, it is possible to suppress the unintentional mixing of the liquid contents discharged from one discharge hole 15 and the liquid contents discharged from the other discharge hole 15.

[0029] Since the cap 14 is formed in a top-shaped cylindrical form having a top wall 14a that covers the upper end of the nozzle cylinder 23, the cap 14 cannot be attached to the cylinder 11 and the nozzle member 13 when it is inverted. The peripheral wall 14b of the cap 14, which is formed in a top-cylindrical shape, opens the nozzle member 13 to the rear and covers the front end opening of the discharge hole 15. As a result, the cap 14 slides in the front-rear direction Y, allowing it to be attached to and detached from at least one of the cylinder 11 and the nozzle member 13. This makes it easy and reliable to align the relative positions of the cap 14 and the cylinder 11 and nozzle member 13 around the axis extending in the vertical direction Z. As described above, when attaching the cap 14 to at least one of the cylinder 11 and the nozzle member 13, it is possible to prevent the relative positions of the cap 14 and the cylinder 11 and nozzle member 13 from being incorrect.

[0030] Since the notch 23a causes the discharge hole 15 to open diagonally upward, facing outward in the left-right direction X when viewed from the front, the discharge hole 15 faces not only forward but also upward, in the direction in which the plunger 12 is pushed. For example, when discharging liquid contents by bringing a pair of discharge holes 15 into contact with or close to the surface to be discharged, it becomes easier to discharge the liquid contents to the desired position while ensuring that the liquid is discharged away from the other discharge hole 15.

[0031] Since the pair of cylinders 11 have first locking projections 24 that protrude outward in the left-right direction X, and the cap 14 is provided with a locking portion 26 that protrudes outward in the left-right direction X and extends in the front-rear direction Y, with its rear end contacting or approaching the first locking projection 24 from behind, the forward movement of the cap 14 relative to the cylinder 11 is restricted, and the cap 14 can be stably attached to the cylinder 11.

[0032] Since the locking portion 26 is elastically displaceable to the cap 14 so that its rear end moves in the left-right direction X, when the locking portion 26 is elastically displaced so that its rear end moves outward in the left-right direction X, the rear end of the locking portion 26 can be separated from the first locking projection 24 of the cylinder 11, and the cap 14 can be moved forward relative to the cylinder 11 and detached from the cylinder 11 and the nozzle member 13.

[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, the notch 23a may be opened diagonally downwards and outwards in the left-right direction X when viewed from the front, or it may be opened straight in the left-right direction X.

[0035] 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]
