Definitions
- the present invention relates to a stopper for a liquid container that is used by piercing a hollow needle for taking out, such as an ink cartridge used in a printing apparatus such as a printer or an infusion container used for medical purposes.
- a liquid container for dispensing a liquid content by inserting a hollow needle into a stopper using a rubber membrane has been widely used as a medical infusion container for a long time.
- the container is disposable, the needle was not inserted and removed many times.
- the content liquid was often colorless and transparent, and even if there was some liquid leakage, it did not cause a big problem.
- the spout described in Patent Document 1 is a spout for solving the above problems.
- an elastic body having a slightly smaller outer diameter is inserted into the cylindrical mouth, and then a crown portion having a protruding pressing portion that presses the elastic body is pressure-bonded to apply pressure to the elastic body. .
- the spout described in Patent Document 2 is a spout for facilitating the deposition of the crown (crown).
- a tapered portion that slidably guides the crown body along the outer peripheral surface of the peripheral wall portion of the mouth portion and a slit that enables elastic deformation of the crown body are provided in the mouth portion.
- the elastic body is expanded in the radial direction by pressing a protrusion provided at the center of the crown in the axial direction. Thereby, a pressing force is applied from the inner peripheral surface of the mouth.
- the spout described in Patent Document 3 is a spout for solving this problem.
- the elastic body enclosed in the mouth is shaped larger than the internal space of the mouth. Further, when the crown is attached to the mouth, an inclined surface inclined with respect to the extraction direction is formed on the inner surface of the crown so that the elastic body sealed in the mouth is pressed over the entire circumference. Yes.
- Patent Document 3 solves the problem of liquid leakage by adopting a structure in which pressure is applied to the elastic body from the entire peripheral surface.
- Patent Documents 1 to 3 apply pressure to the elastic body by forcibly press-fitting the crown.
- the press-fitting of the crown body is performed along the axial direction of the plug body, it is inevitable that the elastic body is compressed in the axial direction even if various measures are taken.
- the elastic body compressed in the axial direction unnecessarily increases the resistance when the needle is pierced in the same axial direction. As a result, the first piercing of the needle makes it difficult to pierce the needle.
- a further problem is that, when the needle that has been punctured is removed, a so-called liquid splash phenomenon occurs in which the liquid that has entered the hole formed by the needle jumps out after the needle to be pulled out.
- this tendency was particularly strong because the elastic body was uniformly compressed from all directions.
- the problem to be solved by the present invention is to provide a spigot in which a needle can be easily inserted and a liquid splash phenomenon can be prevented when the needle is removed.
- a spigot according to one aspect of the present invention is a spigot for a container that contains a liquid, and is stored in the cap main body, a lid body that fits into the plug main body, and the plug main body, and is used for dispensing.
- a plug-shaped main body having an elastic body housing portion for housing the elastic body, a liquid guide path communicating with the elastic body housing portion, and an inner surface facing the elastic body housing portion.

- a groove portion extending in the axial direction is formed between the plurality of vertical ribs. Therefore, it is easy to insert the elastic body in the axial direction, and the elastic body is less likely to be compressed in the axial direction. As a result, the needle can be easily inserted into the elastic body.
- the diameter of the circle passing through the vertices of the plurality of vertical ribs is smaller than the diameter of the cylindrical elastic body. Therefore, an appropriate compressive stress is applied to the elastic body in a direction orthogonal to the axial direction. Therefore, the liquid splash phenomenon when the needle is removed is prevented.
- the length of each of the plurality of vertical ribs protruding in the radial direction from the inner wall surface may be constant in the axial direction.
- the compressive stress applied to the elastic body in the direction orthogonal to the axial direction is substantially constant in the axial direction. Therefore, even if the position of the needle changes, the compressive stress that the needle receives from the elastic body is substantially constant. Therefore, the needle is not bent and the needle can be smoothly guided in the axial direction.
- a gap extending in the axial direction may be formed between the elastic body housed in the elastic body housing section and the groove section.
- the compressive stress applied to the elastic body in the axial direction is reduced in the region between the gap and the axis of the elastic body. Therefore, the needle can be inserted more smoothly.
- the cross-sectional shape perpendicular to the axial direction of the longitudinal ribs is a semicircular shape, and the plug body may have a tapered shape at the opening of the elastic body storage portion.
- the cross-sectional shape perpendicular to the axial direction of the longitudinal rib is a semicircular shape
- the plug body has a tapered shape at the opening of the elastic body storage portion, so that the elastic body can be easily inserted.
- the diameter of the elastic body may be larger than the diameter of the cylinder passing through the vertices of the plurality of vertical ribs and smaller than the diameter of the cylinder passing through the bottom surface of the groove.
- the diameter of the columnar elastic body is larger than the diameter of the cylinder passing through the apexes of the plurality of vertical ribs, and smaller than the diameter of the cylinder passing through the bottom surface of the groove. Therefore, when the elastic body is inserted into the elastic body housing portion, the elastic body can be inserted more easily, and a pressurizing effect on the elastic body can be sufficiently expected.

- a sealing plate may be provided between the elastic body storage portion and the liquid introduction path.
- the sealing plate is provided between the plug body and the elastic body storage portion, it is possible to prevent the elastic body and the content liquid from coming into contact with each other for a long time during storage of the container. Both are prevented from being altered.
- the plug body may have a welding part for welding the container body.
- the plug body since the plug body has a welding portion for welding the container body, it is possible to select a bag-like container as the container body, and it can be developed for various uses.
- the elastic body may have a collar portion at the head, and a corner of the shoulder portion of the collar portion may be chamfered.
- the cylindrical elastic body has a collar portion at the head and the corner of the shoulder portion of the collar portion is chamfered, the elastic body can be easily inserted into the plug body. Furthermore, the lid can be easily attached to the plug body. In addition, liquid leakage is prevented.

- the lid 3 has an elastic body holding part 7 for holding the elastic body 4 and a through part 8 formed at the center of the elastic body holding part and through which the needle 30 for dispensing passes.
- a plurality of vertical ribs 9 extending in the axial direction are formed on the inner wall surface of the plug main body 2 facing the elastic body housing portion 5.
- “Axial direction” means the axial direction of the elastic body storage 5 or the elastic body 4.
- a plurality of groove portions 9g extending in the axial direction are formed between the plurality of vertical ribs 9. Each vertical rib 9 is parallel to the axial direction. Each groove 9g is parallel to the axial direction.
- the inner wall surface of the plug main body 2 is provided with eight vertical ribs 9 and eight groove portions 9g formed therebetween.
- the plurality of vertical ribs 9 are formed at equal intervals in the circumferential direction.
- the cross-sectional shape perpendicular to the axial direction of each vertical rib 9 is a semicircle.
- the cross-sectional shape perpendicular to the axial direction of each vertical rib 9 may be another shape.
- the cross-sectional shape perpendicular to the axial direction of each vertical rib 9 may be trapezoidal, for example.
- the plug main body 2 has a tapered shape at the opening of the elastic body housing 5.
- the shape of each vertical rib 9 is the same.
- the length of each vertical rib 9 protruding in the radial direction from the inner wall surface that is, the protruding width
- the length in which each vertical rib 9 protrudes in the radial direction from the inner wall surface is constant in the axial direction.
- the diameter of the cylinder 9c passing through the apexes of the plurality of vertical ribs 9 is smaller than the diameter of the columnar elastic body 4.
- the elastic body 4 is basically a cylindrical shape, but may be a polygonal column shape that can achieve the same effect as the cylindrical shape.
- the elastic body 4 is accommodated in an elastic body accommodating portion 5 provided in the plug body 2.
- the lower end portion of the elastic body 4 is preferably rounded (see FIG. 7A).
- the diameter of the elastic body 4 is larger than the diameter of the cylinder 9 c passing through the apexes of the plurality of vertical ribs 9.
- the diameter of the elastic body 4 is larger than the diameter of the cylinder 9c passing through the apexes of the plurality of vertical ribs 9, but smaller than the diameter of the cylinder passing through the bottom surface of the groove 9g. Thereby, it becomes easier to insert the elastic body 4 into the elastic body accommodating part 5 of the plug body 2.
- the elastic body 4 is inserted downward from the upper part of the elastic body storage part 5 of the plug body 2. At the start of insertion, the diameter of the elastic body 4 is equal to or slightly larger than the inner diameter of the elastic body storage portion 5, so that it can be easily inserted.
- the elastic body 4 After the tip of the elastic body 4 comes into contact with the vertical ribs 9 provided on the inner wall surface of the plug body 2, the elastic body 4 is pushed in at a stroke to complete the insertion of the elastic body 4.
- the elastic body 4 and the lid body 3 can be attached to the plug body 2 at the same time while the lid body 3 is covered on the elastic body 4.
- silicone rubber As the material of the elastic body 4, silicone rubber, ethylene propylene rubber, styrene elastomer, polyester elastomer and the like are generally used, but are not limited thereto.

- the lid 3 has a function of holding the elastic body 4 so that the elastic body 4 does not fall off.
- the lid 3 has an elastic body holding part 7 for holding the elastic body 4 and a through part 8 formed at the center of the elastic body holding part and through which the needle 30 for dispensing passes. .
- the through portion 8 is a through hole formed in the central portion of the lid 3. If the elastic body 4 is not desired to be exposed to the outside, it may be formed as a thin plate or film instead of a through hole. Another protective component such as a rounded aluminum foil may be placed on the elastic body 4.
- the method for attaching the lid 3 to the plug body 2 is not particularly limited.
- the fitting protrusion 15 provided on the inner surface of the lower end of the lid 3 is fitted and fixed in the fitting groove 14 provided in the plug body 2.
- the fitting protrusion 15 has an annular shape that is continuous over the entire circumference, but does not necessarily have to be continuous over the entire circumference. Claw-like structures provided at several places on the circumference may be used, or screws that are screwed together may be provided on the inner periphery of the lid 3 and the outer periphery of the neck portion of the plug body 2.
- the lid 3 attached to the plug body 2 is pressed against the plug body 2.
- the lid 3 is not pressed against the elastic body 4. Thereby, it is difficult to apply an axial compressive stress to the elastic body 4.
- the elastic body 4 has a cylindrical shape before being inserted into the elastic body storage portion 5. Since the diameter of the cylinder 9 c passing through the apexes of the plurality of vertical ribs 9 is smaller than the diameter of the elastic body 4, after the elastic body 4 is inserted into the elastic body storage portion 5, a part of the outer periphery of the elastic body 4 is vertical. It comes into contact with the rib 9 and the portion is constricted (see FIG. 10A). In other words, the elastic body 4 is pressurized by the surfaces of the longitudinal ribs 9 extending in the axial direction.
- a plurality of gaps 25 are formed between the elastic body 4 housed in the elastic body housing section 5 and the groove 9g. Each gap 25 extends in the axial direction. In addition, the clearance gap 25 does not need to be formed when the elastic body 4 closely_contact
- the elastic body 4 In the constricted portion of the elastic body 4, the elastic body 4 is compressed in the horizontal direction (that is, the direction orthogonal to the axial direction). For this reason, in the elastic body 4, the non-compressed part 26 and the compressed part 27 are formed so as to be alternately arranged on the same circumference. In this case, the center of the circle substantially coincides with the central axis L of the elastic body storage portion 5.
- the non-compressed portion 26 is a portion where the compressive stress is smaller than a predetermined stress.
- the compression part 27 is a part whose compressive stress is larger than a predetermined stress.
- the plurality of compression portions 27 are formed in a lower region (region on the liquid guide path 6 side) A of the elastic body 4 surrounded by the plurality of vertical ribs 9.
- the several compression part 27 is formed in the circumferential direction at equal intervals.
- the compression part 27 is formed between each vertical rib 9 and the central axis L of the elastic body storage part 5.
- the length in the radial direction of the region where the compression part 27 is formed is about 1/3 to 1/2 of the radius of the elastic body 4.
- each groove 9g protrudes in the radial direction from the inner wall surface is constant in the axial direction. Therefore, as shown in FIG. 10B, the length (width) in the radial direction of the compression portion 27 is constant in the axial direction. In other words, in the region A below the elastic body 4, the cross-sectional structure is the same in each cross section in the axial direction.
- the plurality of non-compressed portions 26 are formed between the plurality of compressed portions 27 in a region A below the elastic body 4 surrounded by the plurality of vertical ribs 9.
- the non-compressing portion 26 is formed between each groove portion 9 g and the central axis L of the elastic body storage portion 5. Since the gap 25 is formed between the elastic body 4 and the groove 9g, the compressive stress in the direction orthogonal to the axial direction is reduced in the non-compressed portion 26.
- a region B (region on the penetrating portion 8 side) B above the vertical rib 9 is a non-compressed portion 26.
- the region excluding the compression portion 27 is the non-compression portion 26.
- the spigot 1 has a welded portion 12.
- the welding part 12 is a part for attaching the plug body 2 to the container body 20.
- the welded portion 12 has a rhombic planar shape.
- the cap body is fixed to the container body 20 by attaching and welding the opening of the bag-shaped container body 20 so as to sandwich the short diameter direction of the rhombus.
- the stopper 1 After the stopper 1 is welded to the container main body 20, the content liquid D is filled into the container main body 20 whose periphery is sealed through the penetration portion 8.
- the welding portion 12 of the plug body 2 is provided with three welding ribs 12r.
- the welding rib 12r protrudes slightly from the surface of the welding part 12 in a horizontal streak shape, and serves to prevent the pressure from being dispersed when the container body 20 is welded and to ensure that welding is performed. .
- various forms are selected according to the material and structure of the container body 20.
- a disc-shaped flange portion is formed on the lower surface of the spigot body, and this flange portion is welded to a round hole opened in the bag-shaped container body.
- the container main body is a rigid bottle
- the container main body and the plug main body may be screwed together, or the container main body and the plug main body may be attached by a stopper as a fitting structure. .
- the flange portion 16 shown in FIGS. 1 to 6 is for accurately mounting the container body 20 in the resin case 40.
- the container body 20 to which the spigot 1 is attached is accommodated in a long case 40.
- the flange portion 16 of the cap 1 is fitted into the one end portion 40 a of the case 40, the container body 20 is mounted on the case 40 and the cartridge 50 is completed. From one end of the cartridge 50, the lid 3 of the plug 1 and a part of the plug body 2 protrude.
- the cartridge 50 is inserted into a predetermined position of a printing apparatus such as a printer.
- the direction in which the cartridge 50 is inserted differs depending on the printer or the like.
- the cartridge 50 is inserted in the horizontal direction, for example.
- the needle 30 fixed inside the printer or the like passes through the through portion 8 of the plug 1 and pierces the elastic body 4.
- the needle 30 When the needle 30 is pierced into the elastic body 4, the needle 30 is first pierced into the non-compressed portion 26 formed in the region B. Therefore, the needle 30 can be easily stabbed.
- the tip of the needle 30 reaches the region A surrounded by the vertical ribs 9, the needle 30 advances in the non-compressed portion 26 formed between the plurality of compressing portions 27.
- An appropriate compressive stress is applied to the non-compressed portion 26 in a direction orthogonal to the axial direction. Therefore, the needle 30 advances stably. Since the compressive force applied to the compression part 27 from each vertical rib 9 is uniform, the compressive stress in the non-compression part 26 is also uniform in the circumferential direction.
- the needle 30 Since the compressive stress in the center axis L is the smallest, the needle 30 is guided to the center (center axis L). As a result, the needle 30 is guided so as to approach the normal position. Even when the needle 30 is close to the compression unit 27 or stabbed in the compression unit 27, the compression unit 27 is a region compressed in a direction orthogonal to the axial direction, and thus the needle 30 advances in the axial direction. There will be no problem.
- the elastic body 4 almost no compressive stress in the axial direction is applied, but compressive stress in the direction orthogonal to the axial direction is applied.
- the elastic body 4 is compressed in the direction orthogonal to the axial direction and is not compressed in the axial direction.
- the elastic body 4 is compressed and held in the direction orthogonal to the axial direction by the plug body 2. Therefore, resistance to the needle 30 when the needle 30 is inserted is reduced.
- the needle 30 can be easily inserted in a stable state (that is, in a state in which straightness is maintained). Furthermore, the needle 30 is difficult to bend during the insertion process.
- the tip 30 a of the needle 30 penetrating the elastic body 4 is in contact with the content liquid D.
- FIGS. 12A and 12B a needle hole E is formed in the region A after the tip 30a of the needle 30 has passed.
- the needle hole E is gradually closed as the needle 30 is pulled out.
- the portion of the needle hole E that opposes the compression portion 27 receives a compressive stress in the radial direction and is contracted in the radial direction to be concave. That is, the elastic body 4 protrudes inward in the radial direction.
- the portion of the needle hole E that faces the non-compressed portion 26 protrudes in the radial direction and has a convex shape. That is, the elastic body 4 contracts radially outward. In this way, the needle hole E is gradually closed while being formed in a radial shape.
- the needle hole E is formed as a gap between a portion compressed by the vertical rib 9 and a portion not compressed by the vertical rib 9. Through this gap, the content liquid D easily returns to the inside of the container body 20 (that is, the liquid introduction path 6 side).
- the needle hole E is further reduced while maintaining the above-described radial shape. That is, the needle hole E is formed as a gap between a portion compressed by the vertical rib 9 and a portion not compressed by the vertical rib 9. Through this gap, the content liquid D easily returns to the inside of the container body 20 (that is, the liquid introduction path 6 side). This radial structure prevents the needle hole E from closing immediately after the tip 30a of the needle 30 passes.
- the structure of the spigot 1 is a structure in which the content liquid D such as ink is hardly left in the needle 30 or at the mouth.
- the plurality of vertical ribs 9 extending in the axial direction are formed on the inner wall surface of the plug body 2 facing the elastic body storage portion 5. Between the plurality of vertical ribs 9, grooves 9g extending in the axial direction are formed. Therefore, it is easy to insert the elastic body 4 in the axial direction, and the elastic body 4 is less likely to be compressed in the axial direction. As a result, the needle 30 can be easily inserted into the elastic body 4.
- the diameter of the circle 9 c passing through the apexes of the plurality of vertical ribs 9 is smaller than the diameter of the cylindrical elastic body 4. Therefore, an appropriate compressive stress is applied to the elastic body 4 in a direction orthogonal to the axial direction. Therefore, the liquid splash phenomenon when the needle 30 is removed is prevented.
- a plug having a cavity as a liquid reservoir in an elastic body is known.
- forming such a cavity in an elastic body makes it difficult to mold the elastic body.
- the plug 1 of the above embodiment it is not necessary to provide a cavity as a liquid reservoir in the elastic body, and the elastic body 4 can be easily molded.
- the content liquid D can be flowed to the container body 20 side. Further, even if the needle 30 is inserted and removed a plurality of times, no liquid leaks.
- a gap 25 extending in the axial direction is formed between the elastic body 4 and the groove 9g, so that the region between the gap 25 and the axis of the elastic body 4, that is, the non-compressed portion 26, is located with respect to the elastic body 4.
- the compressive stress applied in the axial direction is reduced. Therefore, the needle 30 can be inserted more smoothly.
- the cross-sectional shape perpendicular to the axial direction of the vertical ribs 9 is a semicircular shape, and the plug body 2 has a tapered shape at the opening of the elastic body housing part 5, so that the elastic body 4 can be easily inserted.
- the cylindrical elastic body 4 when the cylindrical elastic body 4 is inserted into the elastic body housing part 5 of the spigot body 2, it can be easily inserted since it has almost the same diameter at the beginning of the insertion.

- the penetrating portion 8 of the lid 3 is covered with a thin protective plate 10.
- a thin sealing plate 11 is provided between the elastic body storage portion 5 of the plug body 2 and the liquid introduction path 6.
- the collar portion 13 Since the elastic body 4 has the collar portion 13, the collar portion 13 is in close contact with the upper surface of the plug body 2, so that the sealing performance of the container body 20 is further improved.
- the collar portion 13 is sandwiched between the upper surface of the plug body 2 and the lid body 3 and is compressed in the axial direction. However, since this influence does not reach the central portion of the elastic body 4, it is necessary to insert and remove the dispensing needle. There is no adverse effect on it.
- the elastic body 4 can be easily inserted into the plug body 2. Furthermore, the lid 3 can be easily attached to the plug body 2. In addition, liquid leakage is prevented.
- the protective plate 10 is provided in the penetrating portion 8 of the lid 3, the elastic body 4 is not exposed to the outside, and dust can be prevented from accumulating on the upper surface of the elastic body 4. Since the protective plate 10 is thin, it does not hinder perforation by the dispensing needle 30. In addition, the presence of the protective plate 10 in an intact state also proves that the package is unopened.
- the thin sealing plate 11 is provided between the elastic body storage portion 5 of the spigot body 2 and the liquid guide path 6, the content liquid and the elastic body 4 are allowed to remain in the unused state of the container main body 20. Direct contact can be prevented. This can prevent the content liquid from being adversely affected by being in contact with the elastic body 4 for a long period of time or being deteriorated by the elastic body 4 being in contact with the content liquid.
- the sealing plate 11 is also thin, it does not prevent perforation by the dispensing needle 30.
- the content liquid D (contents) cannot be filled from a stopper when the sealing plate 11 is provided in the stopper 1, in the example shown in FIG. A part of the sealing portion is left unsealed, and after the content liquid D is filled from here, the sealing is finally performed.
- the spigot 1 of the above embodiment is easy to assemble because it has a simple structure, and is easy to pierce the needle 30 and the like, and is not easily leaked. In addition, it has excellent advantages such as no splashing when the needle 30 is removed.
- the plug 1 can be suitably used as a plug of a container that stores various liquids.
- the plug of the present invention is not limited to the above embodiment.
- the length of the plurality of vertical ribs 9 protruding in the radial direction from the inner wall surface may vary in the axial direction. That is, the longitudinal rib 9 may have a tapered shape that is slightly inclined in the axial direction.
- the number of the vertical ribs 9 and the groove portions 9g is not particularly limited. The number or the protruding width of the vertical ribs 9 may be changed according to the shape, material, or size of the elastic body 4 to be held.
- the needle can be easily inserted, and the liquid splash phenomenon when the needle is removed can be prevented.
