Description

  The present invention relates to a spout, a cap, and a fluid container, and more particularly, to a spout, a cap, and a fluid container suitable for dispensing a liquid having a relatively high viscosity.

  A fluid that is a relatively highly viscous liquid such as ketchup is generally contained in a synthetic resin container and squeezed out from a cap attached to the container mouth. In order to squeeze out the fluid, the content fluid is pushed out from the spout of the cap by crushing the synthetic resin container. After that, by removing the crushing force, the synthetic resin container tends to swell to its original shape due to elasticity, and the fluid that was being pushed out at the spout is sucked into the synthetic resin container and pushed out of the spout. The fluid that had been left leaves the spout and falls. In this manner, leaving from the spout after pouring is referred to as running out of liquid.

However, in a fluid with a relatively high viscosity, this liquid breakage is poor, and the fluid remains on the cap, stains the cap and deteriorates its appearance, and the remaining fluid clogs the spout by subsequent evaporation of moisture. In some cases, foods are not preferred for hygiene purposes. In view of this, a cap has been proposed in which the spout has three or more slits extending radially from the intersection and the slits are closed in a no-load state (see, for example, Patent Document 1).
JP 2004-142805 A (FIGS. 1 and 2)

  However, even in the cap described above, the fluid remaining after squeezing is elastically deformed and the fluid is prevented from splashing by the slit that opens and closes, so that the fluid is easily drained. Sometimes it remained. Accordingly, an object of the present invention is to provide a spout, a cap, and a fluid container that are excellent in running out of liquid so that the fluid does not remain in the spout.

In order to solve the above-described problem, the fluid spout contained in the container according to the first aspect of the present invention has a cylindrical boss 20 through which the fluid flows, for example, as shown in FIGS. And a gap forming member 30 that is formed inside the boss 20 and forms a thin plate-like gap 40 through which the fluid flows. The gap 40 is perpendicular to the direction in which the fluid flows. The cross section is formed to have an open curve shape.

According to this structure, is formed open curve-shaped gap by the boss and the gap forming member, the fluids are dispensed through the gap, fluids so are dispensed into a thin film shape, easily broken liquid Become. Further, the gap is formed in an open curve rather than a straight line, and the cross-sectional area of the gap can be increased with respect to the thickness of the boss, so that a fluid having a desired flow rate can be poured out. Note that the open curved shape, rather than a closed curve has an end portion of the two positions, it means a curve which does not intersect itself, comprises a straight line which is bent in a curve, by for example, C-shaped, etc. U-shaped is there.

  Moreover, in the spout according to the invention described in claim 2, for example, as shown in FIG. 2, in the spout 2 described in claim 1, the open curve shape may be C-shaped. The C-shape is a shape in which a part of the annular shape is missing, and includes a case where the annular shape is missing due to a rib connecting the boss 20 and the gap forming member 40.

  With this configuration, a cylindrical boss and a columnar gap forming member can be used. In that case, a gap is formed by connecting the cylindrical boss and the columnar gap forming member with a rib. Therefore, manufacture of the spout becomes easy.

Further, in the spout of the invention according to claim 1, for example, as shown in FIG. 2, the gap between the 40, the closing member 34 for closing a portion of the gap 40 in the cross section, the ribs 32 in the cross-section Ru provided on the opposite side.

  If comprised in this way, the pouring of a fluid will be prevented with the obstruction | occlusion member, and the fluid poured out from a clearance gap will become thin in the part corresponded to the location with the obstruction | occlusion member, Therefore It will become easy to run out of liquid further.

Further, in the spout of the invention according to claim 1, for example, as shown in FIGS. 2 and 4, the flow direction of the end portion 36 of the closed covering section member 34, at the end of a direction in which the flow animals flows as a distribution the distribution of thickness of the flow animal has two peaks release the recessed portion which has been closed by the closure member 34, you positioned upstream of the flow direction the from the end of the boss 20.

  With this configuration, the fluid that has been prevented from being poured out by the closing member spreads out to the end of the boss, that is, the gap without the closing member in front of the outlet to be poured out, and is poured out thinly. It becomes easy to cut.

  Moreover, in the spout according to the invention described in claim 5, for example, as shown in FIG. 2, in the spout 2 according to any one of claims 1 to 4, the end in the direction in which the fluid flows is provided. In this part, the inner surface of the boss 20 may be expanded so that the gap forming member 30 is separated from the boss 20.

  With this configuration, since the surfaces of the boss and the gap forming member are inclined so that the gap is widened at the outlet that is poured out from the gap, the fluid that adheres to the outlet after being poured out forms a boss or gap. It adheres to the gap side of the member and can be prevented from adhering to the outside of the gap after pouring.

  In order to achieve the above object, a cap that is fastened to the container according to the invention described in claim 6 and that covers the opening formed in the container is, for example, as shown in FIG. A cap body 10 having a surface on which the spout 2 according to any one of claims 1 to 5 is formed; and a protrusion 55 that is foldably connected to the cap body 10 and engages with the spout 2. And an overcap 50.

  If comprised in this way, since it is equipped with the cap main body which has the spout which is easy to run out of liquid, and the overcap which has the protrusion engaged with a spout, it will be easy to run out of liquid, and it will be projected by covering with an overcap. To seal the spout and become a cap with no fluid remaining outside.

In the cap according to the invention described in claim 7, for example, as shown in FIG. 1, in the cap 1 described in claim 6, the spout 2 is located on the surface 14 where the overcap 50 is connected. It may be formed at a position close to the opposite side. Further, the spout 2 may be formed in such a direction that the rib 32 comes to the side to which the overcap 50 is connected.

  With this configuration, when pouring the fluid, it is easy to use when pouring the fluid from the spout with the cap sideways or diagonally downward and the overcap facing upward, It won't get on the cap or cap body. Further, when the overcap is closed, the distance between the spout and the protrusion is increased, so that the engagement is facilitated.

  In order to achieve the above object, a fluid container according to an eighth aspect of the present invention includes, for example, a container 70 containing a fluid and elastically deforming by an external pressure, as shown in FIG. The cap 1 according to claim 6 or claim 7 is provided.

  If comprised in this way, it will be easy to use since it will become easy to run out of a liquid and it will become a fluid container which has a cap by which a fluid does not remain outside by covering with an overcap. Note that elastically deforming is not strictly elastic, i.e., it may not be restored to its original shape by removing external force, or it may be a little to restore to its original shape by removing external pressure. It only has to be deformed. When the external pressure is removed, the container is slightly deformed, that is, swells, so that the fluid flows in the direction opposite to that at which the fluid is poured out, and the fluid remaining outside the outlet is discharged into the outlet. Returned.

  According to the spout of the present invention, it is provided with a boss through which the fluid flows inside, and a gap forming member that is formed inside the boss and forms a gap through which the fluid flows between the boss and the gap is the fluid. In the cross section perpendicular to the direction in which the liquid flows, it is formed so as to have an open curve shape, so that the fluid is poured out from the gap as a film, and the liquid easily breaks.

  In addition, according to the cap of the present invention, the cap body having a flat surface in which the boss of the spout is formed on one end surface of the cylindrical shape, and a part of the cylindrical surface on the end surface side of the cap body are bent. Since it is provided with an overcap having a projection that is connected and engages with the boss, it is easy to run out of liquid, and the fluid does not remain outside by covering with the overcap.

  In addition, according to the fluid container according to the present invention, the container includes the container that encloses the fluid and is elastically deformed by the external pressure, and the cap that is fastened to the container. By covering with, it has a cap that does not leave the fluid outside, and is easy to use as a fluid container.

  Embodiments of the present invention will be described below with reference to the drawings. In each figure, the same or equivalent devices are denoted by the same reference numerals, and redundant description is omitted.

  With reference to FIG. 1 and FIG. 2, the container 100 for fluids which is embodiment of this invention is demonstrated first. FIG. 1 is a partial perspective view of the vicinity of the cap 1 of a fluid container 100 in which the cap 1 is attached to a container 70 containing fluid. 2A and 2B are diagrams for explaining the cap 1. FIG. 2A is a top view of the overcap 50 opened, FIG. 2B is a sectional view taken along line XX in FIG. 2A, and FIG. Sectional drawing, (d) is a developed view of the gap 40, the rib 32, and the closing member 34 in a plane including the gap 40, and (e) is a ZZ sectional view of (d). In FIGS. 2A and 2B, the overcap 50 is partially omitted.

  The fluid contained in the container 70 is a relatively highly viscous liquid such as ketchup, mayonnaise, adhesive, caulking material, and typically has a viscosity of 100 mPa · sec or more. The container 70 is a bottle container manufactured by a three-layer film of low density polyethylene (LDPE) / ethylene vinyl alcohol (EVOH) / low density polyethylene (LDPE) that is generally used. The container 70 is a flexible container, and can be easily deformed and pushed out the fluid inside by being pushed by hand and applying external pressure. Further, the container 70 stops being pushed by hand, and when the external pressure is removed, the container 70 tries to return to its original shape by the elastic restoring force of the container 70 itself. That is, the container 70 tends to swell. In addition, this elastic restoring force does not require the force of returning to an original shape completely.

  The container 70 is provided with one opening, and the cap 1 is connected to the opening using a joining method such as screwing to cover it. The cap 1 includes a cap body 10 that covers the opening of the container 70, and an overcap 50 that is foldably connected to the cap body 10 via a hinge 60. The cap body 10 has a cylindrical side portion 16, one end surface of which is closed by a flat surface 14, and the other end surface is opened. The plane 14 has a step protruding from the side portion 16. A female screw 12 is formed on the inner surface of the cylindrical side portion 16 and is screwed into a male screw (not shown) formed in the opening portion of the container 70 from the other open end surface. Are connected. When a knurling is formed on the outer surface of the cylindrical side portion 16 of the cap body 10, it is easy to tighten the cap body 10 when screwed into the container 70.

  A hinge 60 is connected to the outer surface of the cylindrical side portion 16. The hinge 60 is connected to the closed end face of the cap body 10. Here, “close to the end face” means not near the open end face. As shown in FIG. 1, the hinge 60 is a thin plate, and is a member that connects the cap body 10 and the overcap 50 and is formed of an elastic material.

  Here, a more preferable structure of the hinge 66 will be described with reference to the drawing for explaining the hinge of FIG. FIG. 3A is a perspective view of the cap 1 with the overcap 50 open, and FIG. 3B is a side view of the cap 1 viewed from the hinge 66 side with the overcap 50 closed. These are the XX arrow directional views in (a). The hinge 66 takes the shape of a bow tie as shown in FIG. 3B when viewed from the outside with the overcap 50 fitted to the cap body 10. The hinge 66 is formed in a substantially drum-shaped film, and has a width of, for example, approximately one third of the entire width in the central portion in the width direction (direction perpendicular to the direction connecting the cap body 10 and the overcap 50). , Having a strip-like portion 62 that is thicker than the other portions. A groove 63 is formed in the band-shaped portion 62 in the width direction of the hinge 66 (that is, the width direction of the band-shaped portion 62) at an intermediate position between the cap body 10 and the overcap 50, and the film of the groove 63 portion is thin. It has become. Outer coupling portions 64 are connected to both sides of the belt-shaped portion 62 at an angle so as to gradually move away from the closed surface side of the cap body 10 and the surface side of the overcap 50 in contact with the cap body 10.

  When the hinge is configured in this way, when the overcap 50 is opened and closed, the overcap 50 swings around the groove 63 formed in the belt-like portion 62 of the hinge 66 and gradually opens from the closed state. The outer connecting portion 64 is pulled by the cap body 10 and the overcap 50 as a whole while being bent into the cap body 10 and the overcap 50. Therefore, when the opening degree of the overcap 50 is increased to some extent, the reverse force acts on the contrary and opens at a stretch without any external force. That is, a snap motion is performed. Here, when the film thickness of the outer connecting portion 64 is not uniform and the connecting portion between the cap body 10 and the overcap 50, that is, both ends are formed thin, the outer connecting portion is mainly deformed at both ends. The entire 64 is deformed. Therefore, the deformation of the outer connecting portion 64 appears greatly, and the opening degree of the overcap 50 increases. On the other hand, when the overcap 50 is closed from the open position, it is automatically closed when it is closed to some extent. That is, it is easy to use because the overcap 50 is stable in the wide open state and the closed state.

  Returning to FIGS. 1 and 2, the description of the fluid container 100 will be continued. The overcap 50 has a cylindrical shape whose one end surface is closed by a surface, has the same outer diameter as the cap body 10, and has an inner diameter that fits the surface 14 having the protruding step of the cap body 10. . The side of the overcap 50 opposite to the side where the hinge 60 is connected has a locking portion 52 that protrudes in a radial direction like a brim of a baseball cap and makes it easy to put a hand when the overcap 50 is opened. On the inner surface side of the closed surface of the overcap 50, a projection 55 that fits into the spout 2 described later is formed. When the overcap 50 is closed, the projection 55 of the overcap 50 fits into the spout 2. The spout 2 is sealed.

  A spout 2 is formed on the surface 14 of the cap body 10. The position of the spout 2 may be the central portion of the surface 14, but it is preferable that the position of the spout 2 is located on the opposite side of the position where the hinge 60 that connects the cap body 10 and the overcap 50 is connected. By bringing the spout 2 in this way, when the fluid is poured out from the fluid container 100, the overcap 50 is opened upward, and the fluid can be easily poured out from the spout 2 located on the lower side. In addition, the overcap 50 swings around the hinge 60 so as to be combined with the cap body 10, and at this time, the projection 55 and the spout 2 are engaged, but the projection 55 and the spout 2 are swung. By moving away from the central hinge 60, it becomes easier to engage.

  The spout 2 includes a boss 20 that forms a flow path through which a fluid poured out from the container 70 flows, and a gap forming member 30 that is disposed in the flow path of the boss 20 and uses the flow path as a thin plate-like gap. A gap 40 that is a flow path of the fluid having an open curve shape is formed. As shown in FIG. 2A, in the present embodiment, the cylindrical boss 20 has a columnar shape, and the rib forming member 30 is formed with a gap between the outer diameter is smaller than the inner diameter of the boss 20 and a gap is formed therebetween. As a result of the connection, the annular gap is cut by the rib 32 to form a C-shaped gap. The gap forming member 30 is shaped like a cylinder with the end face on the container 70 side closed, with the central portion of the columnar shape removed from the side to be dispensed leaving a part or outline, saving material and light weight. It is planned. The rib 32 may be formed to have a uniform width (in the gap 40, the direction perpendicular to the direction in which the fluid flows is the width direction, the length in the width direction is the width, and so on). As shown in the development view of (d), the width may be gradually narrowed in the direction in which the fluid is poured out (the direction of the arrow in FIG. 2 (d)). As shown in FIG. 2A, when the rib 32 is disposed on the side of the gap 40 that is connected to the overcap 50, the rib 32 is removed from the gap 40 when the fluid is poured out with the overcap 50 facing upward. The fluid to be dispensed is preferable because it has a thin film shape with an open top.

  The inner surface of the boss 20 and the gap forming member 30 sandwiching the gap 40 are formed so as to be separated from each other at the end (exit) in the direction in which the fluid flows. That is, the inner surface of the boss 20 and the gap forming member 30 are formed obliquely so that the height (thickness) of the gap is increased. Further, on the fluid outlet side, the diameter of the outer surface of the boss 20 is reduced, the diameter for removing the central portion of the gap forming member 30 is increased, and the thickness at the outlet of the boss 20 and the gap forming member 30 is reduced. May be.

  As shown in the top view of FIG. 2A or the developed view of FIG. 2D, the gap 40 is formed with a closing member 34 that closes a part of the gap 40 as a flow path. The closing member 34 connects the boss 20 and the gap forming member 30 in the same manner as the rib 32 between the gaps, and is preferably installed at the center of the gap 40 in the width direction. That is, it is installed on the opposite side to the rib 32. As shown in FIG. 2D, the closing member 34 is disposed from the container 70 side of the gap 40, and the tip 36 is formed on the fluid outlet side before the tip of the boss 20. That is, the gap 40 is not penetrated in the length direction of the gap 40 (the direction in which the fluid flows in the gap 40 is the length direction; the same applies hereinafter). Further, the tip 36 is formed in an arc shape, and is gradually formed thinner as shown in the sectional view of FIG. That is, the gap forming member 30 is not connected and is formed so as to become thinner gradually. Note that the distal end of the closing member 34 may not be the arc-shaped distal end 36 and may not be gradually formed thinner.

  It is preferable that the cap 1, that is, the cap body 10, the overcap 50, and the hinge 60 are integrally manufactured by injection molding. The cap body 10 preferably includes the spout 2 and is integrally injection-molded including the boss 20 of the spout 2, the gap forming member 30, the rib 32, and the closing member 34. The cap 1 is preferably made of polypropylene, but may be other synthetic resins. As the synthetic resin, ethylene homopolymers or copolymers, propylene homopolymers or copolymers, ionomer resins, polyamides, and polyesters are preferably used. As the ethylene-based copolymer, an ethylene-α-olefin copolymer having 4 to 10 α-olefin carbon atoms is preferable, and ethylene-butene of linear low density polyethylene (LLDPE) or linear very low density polyethylene (VLDPE). 1 copolymer, ethylene-hexene-1 copolymer, ethylene-4 methylpentene-1 copolymer, ethylene-octane-1 copolymer, and ethylene-decene-1 copolymer can be preferably used. Other ethylene copolymers include ethylene-vinyl acetate copolymer, ethylene-methyl acrylate copolymer, ethylene-ethyl acrylate copolymer, ethylene-butyl acrylate copolymer, ethylene-methacrylic acid. A methyl copolymer, an ethylene-ethyl methacrylate copolymer, and an ethylene-butyl methacrylate copolymer can be preferably used. As the ethylene homopolymer, low density polyethylene, medium density polyethylene, and high density polyethylene can be preferably used. As the propylene homopolymer, polypropylene can be preferably used. Furthermore, as a propylene-type copolymer, a propylene-ethylene copolymer and a propylene-norbornene copolymer can be used preferably. For ease of use during the manufacturing process and product use, if necessary, the above synthetic resin may be added to a lubricant such as silicon, for example, an antiblocking agent such as silica or amide, a pigment for coloring, and thermoforming. You may add suitably the heat stabilizer for suppressing the resin degradation at the time, and the other synthetic resin for adjusting the ease of the molten resin flow at the time of thermoforming.

  Then, with reference to FIG. 1 and FIG. 2, the effect | action of the cap 1 and the fluid container 100 which have the above-mentioned spout 2 is demonstrated. After opening the overcap 50 and opening the spout 2, the container 70 is crushed by pushing the container 70 containing the fluid by hand and applying external pressure, and the fluid is pushed out. Since the cap 1 and the container 70 are screwed together, they do not leak from the boundary, and the fluid is poured out from the spout 2 of the cap 1.

  Here, the fluid poured out from the gap 40 will be described with reference to FIG. First, the thickness distribution of the fluid will be described with reference to FIG. FIG. 4 (a) is a diagram schematically showing the thickness distribution of the fluid at the outlet in the development of the gap 40 shown in FIG. 2 (d). The lower side of FIG. 4A is the container side, and the upper side is the outlet side of the fluid. In the spout 2, the fluid flows through the gap 40 from the container 70 side toward the outlet. That is, it flows from the bottom to the top in FIG. At that time, since the closing member 34 is formed, it passes through the gap 40 divided into two by the closing member 34. As the width of the rib 32 becomes narrower as it approaches the outlet side, the width of the gap 40 becomes wider conversely, and the fluid tends to spread slightly but thinly. Further, when approaching the outlet, the tip 36 of the closing member 34 is formed in an arc shape, and in addition, the gap forming member 30 is opened, so the gap 40 divided into two is formed. When the flowing fluid approaches the outlet 36 of the closing member 34 or the outlet from the tip 36, it is connected to one. Therefore, the distribution of the thickness of the fluid at the outlet is a distribution having two ridges that are dented at the place closed by the closing member 34.

  As shown in FIG. 4B, the shape of the fluid at the outlet of the spout 2 is formed in a C shape, so that the center and both ends of the rounded thin film are thin, and the outflow The thing is poured out from the spout 2 to the outside. At that time, the rib 32 of the spout 2 is arranged on the side connected to the hinge 60, and the closing member 34 is installed in the center of the gap 40 in the width direction. It is poured out in shape. After the fluid is poured out in this way, if the pushing is stopped by hand, the fluid is no longer pushed out from the spout 2.

  Then, as shown to Fig.5 (a), a fluid will cut out of the spout 2, and it will be divided into the part which falls and the part which remains on the spout 2 side. As shown in FIG. 5B, the fluid remaining on the spout 2 side tends to be rounded due to surface tension. The film-like fluid slides to the lower part outside the spout 2 and is rounded. In this case, since the fluid on the spout 2 side has only the thickness of the gap 40, the fluid on the spout 2 side is easily cut as shown in FIG. At that time, as shown in FIG. 4B, since the film has an open curve shape with a thickness distribution of two ridges indented at the center, it is further easily cut. That is, the liquid runs out better. As the liquid breakage improves, the fluid does not easily remain in the spout 2. When the external pressure of the container 70 is removed, the container 70 tries to return to its original shape by the elastic restoring force of the container 70 itself. At that time, air or the like is sucked from the gap 40. Therefore, the fluid remaining in the gap 40 is returned from the gap 40 to the container 70. Therefore, no fluid remains in the spout 2.

  In particular, as shown in the cross-sectional view of FIG. 2B or 2C, the gap 40 is formed so that the inner surface of the boss 20 and the gap forming member 30 are inclined so as to be separated from each other. The fluid adhering to the spout after being applied is likely to adhere to the gap 40 side between the boss 20 and the gap forming member 30. That is, the fluid adheres to the exit of the gap 40. Therefore, when air or the like is sucked from the gap 40, the air is sucked into the gap 40, and the fluid does not easily remain outside the spout 2. Therefore, it is possible to prevent the fluid from adhering to the outside of the spout 2 and remaining.

  When the fluid is returned to the gap 40 or the container 70 and does not remain outside the spout 2, the overcap 50 is closed to close the cap, and the spout 2 covers the protrusion 55. Because of this, the spout 2 is sealed. As described above, in the cap 1 and the fluid container 100 having the spout 2 according to the present invention, the liquid breakage is good and the fluid does not remain at the spout, so that it can be used cleanly for food hygiene and the overcap 50 Since the sealing performance is improved when the lid is closed with, it is easy to use everyday.

  As shown in the front view of FIG. 6A, the gap forming member 30 is formed in an elliptical shape so that the gap 40 is not uniform in thickness, but thin at the center in the width direction and thick at the periphery. May be. In FIG. 6, the gap 40 is indicated by hatching. That is, the long part of the elliptical shape is arranged at the top and bottom in FIG. By forming in this way, the thickness distribution of the fluid poured out from the spout 2 is thinned at the center. For example, the gap t1 of the thinnest gap 40 and the gap t2 of the thickest gap are set to t1: t2 = 1: 2. By forming the central portion thin, the amount of the fluid collected at the central portion when the pouring of the fluid is stopped is suppressed, and the liquid runs out better. Also in this case, the formation of the closing member 34 generates two peaks of the thickness distribution at the outlet of the gap 40 corresponding to the flow rate of the fluid, and corresponds to a valley between these peaks. Since the effect of running out of liquid becomes large in the region, it is preferable. Alternatively, as shown in the front view of FIG. 6B, the gap forming member 30 is not elliptical and remains cylindrical, and is eccentric in the boss 20, thereby forming a thin central portion of the gap 40. In this region, the effect of running out of liquid may be increased.

  So far, the gap 40 has been described as being formed in a C shape, but the shape of the gap 40 is not limited to the C shape. In the boss 20, any shape may be used as long as the width is widened as an open curve shape in a cross section perpendicular to the fluid pouring direction of the fluid in the gap 40 so that a desired flow rate of the fluid pouring can be secured. . In addition, when the straight shape is used, the diameter of the boss 20 needs to be increased in order to secure a desired flow rate. When the curved shape is a closed curve, the poured fluid does not become a film but becomes a lump and the liquid runs out. The effect becomes smaller.

  FIG. 7 shows an example of a gap shape having an open curve other than the C-shape. FIG. 7A is a perspective view of the spouts 3 and 4 showing an example in which the gap 41 is formed in a U shape, and FIG. 7B is an example in which the gap 42 is formed in a V shape. The spout 3 shown in FIG. 7A has a U-shaped outer shape and uses a hollow boss 21 having a uniform thickness, and a U-shaped gap on the inner surface of the boss 21 that is smaller than the inner surface of the boss 21. The gap 41 is formed by inserting the forming member 38. The U-shaped upper surface (the U-shaped open portion) of the gap forming member 38 is in contact with the upper surface of the U-shaped inner surface of the boss 21. It is preferable that a closing member 34 is formed in a U-shaped lower part (a central part of the U-shaped bend). When the spout 3 is integrally formed by injection molding, the boss 21 and the gap forming member 38 are integrated and difficult to distinguish. However, as described above, the boss 21 and the gap forming member 38 are provided. ing.

  The spout 4 shown in FIG. 7 (b) has a V-shaped outer shape and uses a hollow boss 22 having a uniform thickness. The inner surface of the boss 22 has a V-shaped gap smaller than the inner surface of the boss 22. The gap 42 is formed by inserting the forming member 39. The V-shaped upper surface (the V-shaped open portion) of the gap forming member 39 is in contact with the upper surface of the V-shaped inner surface of the boss 22. It is preferable that a closing member 34 is formed at the lower part of the V shape (the bent part of the V shape). When the spout 4 is injection-molded integrally, the boss 22 and the gap forming member 39 are integrated and difficult to distinguish. However, as described above, the boss 22 and the gap forming member 39 are provided. ing. The shape of the gap, the shape of the boss, etc. may be other shapes.

  So far, the case where the spout according to the present invention is used for the fluid container 100 in which the cap 1 having the relatively short spout 2 is connected to the container 70 as shown in FIG. 1 has been described. Such a spout can also be used for other applications.

  An example in which the spout 7 is used for other purposes is shown in the perspective view of FIG. The fluid container 101 shown in FIG. 8 is a container that can be used, for example, for injecting caulking materials and adhesives for construction, adding oil, or applying mustard at a hot dog store. 7 is formed elongated. The container body 71 encloses the fluid, and the container body 71 and the container tip 5 are joined together by screws or the like. An elongated spout 7 is formed at the container tip 5. A C-shaped gap 46 is formed in the spout 7. The gap 46 is not formed over the entire length of the spout 7 but may be formed only near the tip of the spout 7. In that case, from the base of the spout 7 (the container body 71 side) to the middle, for example, a cylinder whose outer diameter is substantially equal to or slightly larger than the outer shape of the gap 46 (the outer diameter of the circle forming the C-shape). It may be formed as a fluid flow path in the form of a fluid. It is preferable that a blocking member is formed in a portion formed as a C-shaped gap.

  According to such a fluid container 101, since the spout 7 is elongated, it is easy to pour the fluid into a fine part. In addition, since the fluid is poured out from a gap in a closed curve shape such as a C-shape formed in the spout 7, the liquid is well-disappeared and it is possible to prevent the fluid from being poured out to a place other than the intended place. .
