    [0001] [0001] The present invention relates to a syringe. BACKGROUND OF THE TECHNIQUE
    [0002] [0002] A pre-filled syringe is known, in which an external sterile syringe tube is filled with a liquid product in an aseptic manner (see, for example, Patent Document 1). The pre-filled syringe includes: the outer syringe tube having a nozzle, through which the liquid product is ejected, and a locking adapter, rotatably supported on the nozzle; and a cap, mounted on the tip of the external syringe tube and locked by a locking element. When the pre-filled syringe, described in Patent Document 1, is, in its unused state, or in its sealed sealed state, the cap and locking adapter are collectively covered with a film, with a perforation in a state in the which the cap is mounted on the outer syringe tube.
    [0003] [0003] When the pre-filled syringe, in the unused state, is not sealed and the cap is detached, but the cap is then reassembled, that is, the pre-filled syringe is capped, without using the pre-filled syringe, it is impossible to recognize, at first glance, that the pre-filled syringe is in a pre-sealed state. When the cap of a pre-filled syringe is opened once, it is difficult to maintain the aseptic state inside the pre-filled syringe for a long time, and therefore the liquid product needs to be used quickly. If re-capping is done as mentioned above, however, there is a problem in which the re-filled pre-filled syringe, which is of low asepsis, can be put to use, while mistakenly considering it to be in the unused state.
    [0004] [0004] Patent Document 1: Japanese patent publication pending No. 2002-315827. SUMMARY OF THE INVENTION

    [0012] [00012] Furthermore, in the syringe of the present invention, preferably, the groove is formed in one part of the circumferential direction of the other.
    [0013] [00013] Furthermore, in the syringe of the present invention, preferably, the break section consists of several thin parts, intermittently arranged around the axis of the assembly section.
    [0014] [00014] In addition, in the syringe of the present invention, preferably, the part of the main cap body, which abuts against the nozzle, to seal the nozzle, consists of an elastic body, and the main cap body is provided in the direction of the distal direction by an elastic force of the elastic body.
    [0015] [00015] Furthermore, in the syringe of the present invention, preferably, the main cap body has a clamping section, which is flat in shape and which is clamped when the rotation operation is conducted. BRIEF DESCRIPTION OF THE DRAWINGS

    [0022] [00022] Then, a syringe according to the present invention will be described in detail below, based on a preferred embodiment shown in the attached drawings.
    [0023] [00023] Figure 1 is a side view showing an embodiment of the syringe according to the present invention; Figure 2 is a detailed perspective view of a distal end side portion of the syringe shown in Figure 1; Figures 3 and 4 are longitudinal sectional views to show sequentially the process of a syringe opening operation shown in Figure 1; Figure 5 is a view showing the positional relationship between an external syringe tube lock adapter and a cap assembly section, as seen from the direction of arrow A in Figure 3; and Figure 6 is a view showing the positional relationship between the external syringe tube lock adapter and the cap assembly section, as seen from the direction of arrow B in Figure 4. Eventually, below, for convenience of description, the right side in Figure 1 and Figures 3 to 6 will be referred to as a "proximal end", the left side as a "distal end", the upper right side in Figure 2 as a "proximal end", and the bottom side left as a "distal end".
    [0024] [00024] A syringe 1, shown in Figure 1, is a pre-filled syringe, which includes an outer syringe tube (hereinafter referred to simply as the "outer tube") 2, a gasket 3 arranged inside the outer tube 2, in order to be slidable along the longitudinal direction of the outer tube 2, a plunger 4 for gasket movement operation 3, and a cap 5 mounted on a distal end part of the outer tube 2. A space 24, surrounded by the outer tube 2 and by gasket 3, it is pre-filled with a liquid, such as liquid product 200.
    [0025] [00025] The outer tube 2 has an outer tube main body 21, having a tubular shape, and a locking adapter 6 as a locking element, disposed in a distal end part of the outer tube main body 21.
    [0026] [00026] The main body of external tube 21 is formed, in its distal end part, with a section of reduced diameter 22, which is reduced in external diameter and internal diameter. The liquid product 200 passes through the reduced diameter section 22, so that it is discharged through a distal end opening 221 of the reduced diameter section 22. In the outer tube 2, the reduced diameter section 22 and the locking adapter 6, whereby a connecting element connected to the reduced diameter section 22 is locked, they constitute a nozzle 20 of the outer tube 2. Eventually, the locking adapter 6 will be described below. Eventually, the connecting element, to be connected to the reduced diameter section 22, is not specifically limited; examples of the connecting element include a connector disposed at one end or an intermediate part of a tube, a mouth part of an infusion bag, and a hub of an injection needle.
    [0027] [00027] The gasket 3 has a main body of external tube, having a cylindrical shape, and has projections 31 and 32, in which its external circumferential part is enlarged in external diameter. The projection 31 and the projection 32 are spaced apart along the axial direction. The projections 31 and 32 slide while maintaining close contact with an internal circumferential surface 211 of the main body of external tube 21, thereby maintaining gas tightness (liquid tightness) and improving the sliding ability.
    [0028] [00028] The plunger 4 has a long element, of which a distal end part is threaded coupling with the gasket 3. When the liquid product 200 is discharged, the plunger 4 is pushed in the direction of the distal direction, to make gasket 3 expels liquid product 200 from the reduced diameter section 22, with which the discharge can be easily conducted.
    [0029] [00029] As shown in Figures 2 to 4, the locking adapter 6, which constitutes the nozzle 30 of the external tube 2, is annular in shape and is concentrated concentrically in an external circumferential part of the reduced diameter section 22. The adapter of lock 6 is for locking the connecting element connected to the reduced diameter section 22.
    [0030] [00030] In addition, the locking adapter 6 is supported to be movable with respect to the reduced diameter section 22, in the axial direction of the reduced diameter section 22, but is limited in rotation about the axis. For example, as shown in Figures 3 and 4, this support constitution may include several projections 61, formed in an inner circumferential part of the proximal end of the lock adapter 6, and grooves (not shown), which are formed in a circumferential part external section of the reduced diameter section 22, along the axial direction and in which the projections 61 are inserted, respectively.
    [0031] [00031] In a circumferential outer part 62 of the locking adapter 6, a pair of grooves 63 is provided, arranged with their axis between them (see Figures 3 and 4). The slots 63 are parts in which the projections 81 of a mounting section 9 of the cover 5, described below, are inserted, respectively.
    [0032] [00032] Eventually, both grooves can be formed along the entire circumference of the outer circumferential part 62 of the locking adapter 6, but, in this embodiment, they are formed in a part of the circumferential direction of the outer circumferential part 62 (see Figures 5 and 6). Slots 63 have the same configuration; hereinafter, therefore, one of the slots 63 will be described, representatively.
    [0033] [00033] As shown in Figure 5 (and also in Figure 6), the groove 63 can be divided into an inclined section 631, and a perpendicular section 632, formed continuously with the distal end of the inclined section 631.
    [0034] [00034] The inclined section 631 is a part in which a side wall of the groove 63 is formed at an inclination relative to the axis of the locking adapter 6.
    [0035] [00035] The perpendicular section 632 is a part in which the side wall of the groove 63 is formed in a perpendicular direction relative to the axis of the locking adapter 6, that is, formed along the circumferential direction of the outer circumferential part 62 of the adapter. lock 6.
    [0036] [00036] In addition, the outer circumferential part 62 of the lock adapter 6 is formed with grooves 64, along the axial direction of the lock adapter 6, on the side of the distal end of the perpendicular sections 632. At the time of assembly of the cover 5 at the spout 20 of the outer tube 2, the cap 5 is pushed in the direction and on the outer tube 2 on the side of the distal end. The projections 81 of the mounting part 8 are first inserted into the grooves 64, and then inserted into the perpendicular sections 632 by mounting in the parts between the grooves 64 and the perpendicular sections 632.
    [0037] [00037] Thus, when the cap 5 is pushed in the direction and on the outer tube 2, the cap 5 is easily mounted on the locking adapter 6 (see Figure 2). Then, in this condition, the liquid product 200 can be fed from the side of the proximal end of the outer tube 2.
    [0038] [00038] As shown in Figure 3 (and also in Figure 4), the locking adapter 6 is formed in its inner circumferential part with a female thread 65. When the connecting element has a male thread, the female thread 65 can produce a threaded coupling with the male thread. By means of this threaded coupling, the outer tube 2 and the connecting element are firmly connected to each other.
    [0039] [00039] Eventually, the materials constituting the outer tube 2 and the plunger 4 are not specifically limited. Examples of materials include various resins, such as polyethylene, polypropylene, polystyrene, polycarbonate and cyclic polyolefin.
    [0040] [00040] Furthermore, the materials constituting the gasket 3 are not particularly limited. Examples of the material include various rubber materials (especially those vulcanized), such as natural rubber, isoprene rubber, butadiene rubber, styrene-butadiene rubber, butyl rubber, silicone rubber and fluorinated rubber, and also include various elastomers thermoplastics, which can be used alone or as a mixture of two or more of them.
    [0041] [00041] As shown in Figures 1 and 3, when the syringe 1 is in an unused state, the cap 5 is mounted on the nozzle 20 of the external tube 2 (hereinafter, this state will be referred to as "mounted state"). Eventually, in the case in which the syringe 1, in this assembled state, is to be used, the opening can be made by rotating the cap 5 (see Figure 4).
    [0042] [00042] The cover 5 includes a main cover body 7, the mounting section 8 arranged on the proximal end side of the main cover body 7, and a break section 9, which has the function of connecting the main cover body 7 and the mounting section 8 (see Figure 3).
    [0043] [00043] The main cap body 7 includes a tube body 71, having a tubular shape, and a sealing element 72 disposed within the tube body 71.
    [0044] [00044] The tube body 71 functions as a clamping section, which is tightened when the opening is made by rotating the cap 5. As shown in Figure 2, an outer circumferential part 711 of the tube body 71 is shaped so that the width, in one of the radial directions, decreases in the direction of the distal end. This ensures that the tube body 71 has a flat shape, which allows for easy tightening.
    [0045] [00045] As shown in Figure 3, in the inner circumferential parts of the proximal end of the tube body 71, several ribs 73 are formed in projection. All ribs 73 are formed along the axial direction of the tube body 71. In addition, the ribs 73 are arranged, respectively, at regular equiangular intervals around the axis of the tube body 71. In the main cap body 7, the the sealing member 72 is compressed in the part of the tube body 71, in which the ribs 73 are formed.
    [0046] [00046] The sealing element 72 seals the opening of the distal end 221 of the reduced diameter section 22, which constitutes the nozzle 20, in a liquid-tight manner. The sealing element 72 has an elastic disk-shaped body. This ensures that the sealing element 72, in the state of being disposed in the tube body 71, is compressed towards the center by the ribs 73, whereby the sealing element 72 is prevented from sliding out of the tube body 71.
    [0047] [00047] Eventually, in the assembled state shown in Figure 3, the sealing element 72 is compressed by opening the distal end 221 of the reduced diameter section 22 of the outer tube 2. This ensures that the opening of the distal end 221 can be firmly sealed in a liquid-tight way. Furthermore, the sealing element 72 thus compressed is propelling the main cover body 7 towards the direction of the distal end by its own elastic force. This driving force, when separating the main cover body 7 from the assembly section 8, helps the separations.
    [0048] [00048] In the main cover body 7 constituted as above, in the assembled state, the sealing element 72 is in contact with the opening of the distal end 221 of the reduced diameter section 22, so that an additional movement of the main cover body 7 , in the direction of the proximal direction, is limited.
    [0049] [00049] On the side of the proximal end of the main cover body 7, the annular mounting section 8 is arranged. The mounting section 8 is an element to be mounted on the outer circumferential part 62 of the lock adapter 6.
    [0050] [00050] As shown in Figure 3, the mounting section 8 is formed, in its internal circumferential part, with the projections 81. Preferably, several of the projections 81 are provided; in that embodiment, a pair of, or two, projections 81 is provided. These projections 81 are located opposite each other, with the axis of the mounting section 8 between them. As shown in Figure 3, in the assembled state, one of the pair of projections 81 is inserted into the groove area 63 of the lock adapter 6, while the other projection 81 is inserted into the other slot 63 of the lock adapter 6.
    [0051] [00051] Furthermore, as shown in Figure 5, in the state before the opening operation of the lid 5, both projections 81 are located in the perpendicular section 632 of the corresponding slot 63. When the opening operation is conducted, as shown in Figure 6, both projections 81 are moved from the perpendicular section 632 to the inclined section 631, and can be moved along the inclined section 631. This opening operation will be described below.
    [0052] [00052] As mentioned above, in cover 5, both projections 81 are located opposite each other, with the axis of the mounting section 8 between them, and both grooves 63 are formed correspondingly to both projections 81, thus located. This ensures that, when the cap 5 is rotated in relation to the outer tube 2, the rotation operation can be conducted in a stable manner.
    [0053] [00053] As shown in Figure 3, the break section 9 is provided between the main cover body 7 and the assembly section 8. In the assembled state, the break section 9 connects a proximal end 712 of the pipe body 71 of the main cover body 7 and a distal end 82 of the mounting section 8. So, the break section 9 is a part that can release the connection, between the main cover body 7 and the mounting section 8, by breaking when the opening operation is conducted, as shown in Figure 4.
    [0054] [00054] The break section 9 has several thin parts 91, intermittently arranged around the axis of the cover 5 (the mounting section 8). This allows the break section 9 to be easily broken at the time of the opening operation.
    [0055] [00055] Eventually, the number of thin parts 91, which depends on the size and material of the lid 5, is, for example, preferably from two to eight, particularly four to six.
    [0056] [00056] In addition, the thickness of the thin parts 91, which also depends on the size and material of the lid 5, is, for example, preferably from 0.1 to 2.0 mm, particularly from 0.2 to 2.0 mm. 0.6 mm.
    [0057] [00057] Eventually, the material constituting the cap 5 (excluding the sealing element 72) is not particularly limited; for example, the same material as that constituting the outer tube 2 and the plunger 4 can be used. In this case, when manufacturing the lid 5, it is possible to integrally form the main lid body 7 (excluding the sealing element 72), the mounting section 8 and the breaking section 9.
    [0058] [00058] Furthermore, the material constituting the sealing element 72 is not specifically limited; for example, the same material as that constituting the gasket 3 can be used.
    [0059] [00059] Next, the process of opening by rotation of the lid 5, from the assembled state, will be described below with reference to Figures 3 to 6.
    [0060] [00060] As shown in Figure 3, when the syringe 1 is in the unused state, the cap 5 is mounted on the outer tube 2, and the reduced diameter section 22 of the outer tube 2 is sealed in a liquid-tight manner.
    [0061] [00061] Furthermore, in this state, the projections 81 of the mounting section 8 of the cover 5 are located in the perpendicular sections 632 of the slots 63, respectively (see Figure 5).
    [0062] [00062] Then, while the outer tube 2 is clamped by one hand, the main cap body 7 of the cap 5 is clamped by the other hand, and is rotated around the axis of the outer tube 2. In this case, the rotational force applied to the main cover body 7, it is also transmitted to the mounting section 8 by the thin parts 91, and all projections 81 of the mounting section 8 are moved from the perpendicular section 632 to the inclined section 631 (see Figures 4 and 6) . Furthermore, when the rotation operation is continued, all projections 81 of the mounting section 8 are moved along the inclined section 631. Through this movement, the mounting section 8 is gradually moved in the proximal direction, and concurrently, all thin parts 91 are gradually pulled in the same direction. Then, all thin sections 91 are eventually broken when their breaking limit is exceeded (see Figure 4). Therefore, the main cap body 7 can be separated, or uncoupled, from the mounting section 8, so that the syringe 1 remains open.
    [0063] [00063] In addition, when the main cover body 7 is separated, the female thread 65 of the locking adapter 6 of the external tube 2 protrudes (see Figure 4). This allows the locking adapter 6 and the connecting element to be placed in a threaded coupling.
    [0064] [00064] Thus, in this syringe 1, the main cap body 7 and the mounting section 8 are connected together by the thin parts 91, so that the breaking of the thin parts 91 prevents the main cap body 7 and the mounting section 8 are re-connected to each other. This surely prevents an attempt to establish the mounted state again, or an attempt to have a cap successfully obtained, so that it is possible to easily recognize that syringe 1 has already been opened. Therefore, the syringe is excellent in tampering capacity (the property ensuring that the fact that syringe 1 has already been put in the useful state can be configured later), and the misuse of syringe 1, which was previously opened, can be easily prevented from occurring.
    [0065] [00065] Furthermore, since the recapping is prevented, even when the open syringe 1 is violated, the misuse of syringe 1 can be safely prevented from occurring.
    [0066] [00066] Furthermore, as shown in Figures 5 and 6, although all projections 81 of the mounting section 8 can be moved from the perpendicular section 632 to the inclined section 631 of the slot 63, movement in the opposite direction is limited. This limits the operational direction of the rotation operation, so that the rotation operation can be carried out safely in the correct direction, that is, the direction for opening.
    [0067] [00067] Furthermore, as mentioned above, all the grooves 63 of the locking adapter 6 of the outer tube 2 are formed in one part in the circumferential direction of the outer circumferential part 62. This structure ensures that, when rotating, the section mounting element 8 can be pushed quickly in the proximal direction, to be separated from the main cover body 7, in comparison with the case in which, for example, all grooves 63 are formed along the entire circumference of the outer circumferential part 62. Consequently, syringe 1 is easy to open.
    [0068] [00068] Although the syringe according to the present invention has been described above with reference to the embodiment shown in the drawings, the invention should not be limited to that embodiment. All components of the syringe can be replaced by ones having one having an arbitrary constitution, which can have the equivalent function. Furthermore, an arbitrary constitution can be added.
    [0069] [00069] In addition, even though the syringe in the present embodiment has the locking adapter, this constitution is not limiting; for example, the lock adapter can be omitted.
    [0070] [00070] Even more, although the syringe in this embodiment has a constitution in which the external tube (locking adapter) is formed with the grooves, while the cap is formed with the projections to be inserted in the grooves, this constitution is not limiting; for example, a constitution can be adopted in which the outer tube is formed with the projections, while the cap is provided with the grooves in which the projections are to be inserted. INDUSTRIAL APPLICABILITY
    [0071] [00071] The syringe according to the present invention is a syringe including: an external syringe tube having a tubular shape, to be filled with a liquid and provided with a nozzle, through which the liquid passes in an end part distal from it; and a cap mounted on the spout. The lid includes: a main lid body, which seals the nozzle in a liquid-tight manner; an annularly shaped mounting section, which is arranged on one side of the proximal end of the main lid body and is mounted on an outer circumferential part of the nozzle; and a break section, which connects the main cover body and the mounting section, and a connection is breakable. One of an inner circumferential part of the mounting section and the outer circumferential part of the nozzle is formed with at least one projection, while the other is formed with a groove, into which the projection is inserted, and which has an inclined section, which it is inclined in relation to one axis of the other. When the cap is rotated in relation to the outer syringe tube about an axis of the outer syringe tube, the projection moves along the sloped section of the groove, with which the mounting section is moved in a proximal direction, and the break section is pushed in the same direction to break, thereby separating the main cover body from the mounting section, so that the main cover body, thus separated from the mounting section, cannot be reassembled in the nozzle. Therefore, since the main cap body and the assembly section are connected together, via the break section, in an unused state, when the outer tube is rotated to open the syringe, the break section. This makes it impossible to reconnect the main cover body and the mounting section. Consequently, the tip of the external syringe tube is safely prevented from being resealed with the main cap body, which makes it easy to recognize that the syringe has already been opened. In this way, the syringe is excellent at preventing tampering, and the open syringe is safely prevented from being misused. Consequently, the syringe of the present invention has industrial applicability.
