Description

  The present invention relates to a spout plug that is detachably attached to a discharge port of a storage container, and that allows a predetermined amount of contents liquid such as seasonings and liquor stored in the storage container to flow out arbitrarily.

  In some cases, seasonings and liquor are stored in a storage container having a relatively large capacity, and transferred from the storage container to a small bottle for desktop use or the like. In such a case, generally, an openable / closable pouring stopper is attached to the storage container, and the pouring stopper is operated to arbitrarily pour out the content liquid.

For example, as a spout plug, there is a type in which a valve body is movably provided inside a housing attached to a discharge port of a storage container, and the valve body is moved by operating an operation handle or the like to open and close the outlet.

  However, the conventional pouring tap has the following problems.

  In the spout plug having a structure in which the valve body is inserted into the outlet opened in the housing and the outlet is closed, the inner peripheral surface of the outlet and the outer peripheral surface of the valve body when the valve body is inserted into the outlet In this state, the outflow of the content liquid is stopped. Therefore, when the gap between the valve body and the outlet is wide, liquid leakage occurs from the outlet, and conversely, when the gap is narrow, the sliding resistance of the valve body increases and the opening and closing operation of the spout plug becomes difficult. In addition, if the operation is heavy, an excessive force is applied to the operating lever, the threaded portion of the spout, etc., and there is a risk of damage or a decrease in the durability of the spout.

  As described above, it is difficult to seal the gap between the valve body and the outlet to reliably prevent liquid leakage and to lighten the opening / closing operation.

  Further, if the content liquid adhering to the outer surface of the valve body is left as it is after the content liquid has flowed out, the content liquid may dry and the solid component of the content liquid may adhere to the surface of the valve body. Thus, it is not preferable that the solid component is generated around the valve body, and it has been necessary to prevent it particularly when the content liquid is food.

  The present invention is a pouring stopper that stops the outflow of the content liquid by inserting a valve body into the outlet, and the operation is light, and the valve body reliably seals the outlet and causes liquid leakage from the outlet. The purpose is to provide no spout.

  It is another object of the present invention to provide a pouring stopper in which the solid component of the content liquid does not adhere around the outlet.

  In the present invention, in order to solve the above problems, the pouring tap is configured as follows.

1. A vertical cylindrical housing having an inlet connected to a discharge port of a liquid container on a side surface and having a circular outlet at the lower end, and a cylindrical valve in surface contact with the inner peripheral surface of the outlet In a spout tap provided with a valve body having a portion and an operating means provided at the upper part of the housing and opening and closing the outlet by moving the valve body within the housing,
Provided on the entire circumference of either the outer peripheral surface of the valve portion and the inner peripheral surface of the outlet port is a protrusion that contacts the surface facing the surface, and the height of the protrusion is set to the outer peripheral surface of the valve portion and the outlet port The pouring tap was configured so that the surface contact with the inner peripheral surface could be maintained.

  The protrusions may be provided on any one of the outer peripheral surface of the valve portion and the inner peripheral surface of the outlet, or may be provided on both surfaces. Even when the protrusion is in contact with the opposing surface, the protrusion has a height that does not separate the contact between the valve portion and the outlet. The surface contact between the valve portion and the outlet means a state in which the valve portion is slidable and in close contact with each other with almost no liquid leaking out. Therefore, it is preferable that the height of the ridge slightly exceeds the gap between the valve portion and the outlet. In addition, it is necessary for the protrusions to continuously contact over the entire circumference of the opposing surfaces. Further, even if the contact between the upper and lower surfaces sandwiching the protrusion is released by the protrusion, the outer peripheral surface of the valve portion and the inner peripheral surface of the outlet are in surface contact on at least one of the upper and lower sides of the protrusion. It only has to be.

  2. The spout as described in 1 was configured so that the ridge was provided on the outer peripheral surface of the valve portion, and the ridge was located substantially at the center of the inner peripheral surface of the outlet when the outlet was closed. The approximate center of the inner peripheral surface refers to the section where the protrusion is actually in contact until it penetrates and leaves after the valve portion is inserted into the outlet and penetrated. The center.

  3. The pouring tap according to 1 or 2 was configured with a tapered lower end of the valve portion. The tapered surface is preferably conical, but may be polygonal pyramid instead of conical. The generatrix of the tapered surface may be a curved line instead of a straight line.

  4. The taper surface was formed into a conical shape having a right angle between the apexes, and when the outlet was closed, the taper surface and the outer wall surface of the housing were connected to form the spout plug described in 3. Although the sandwiching angle of the tapered surface is a right angle, the sandwiching angle does not have to be a complete right angle, and may have an angle close to a right angle. That the taper surface and the outer wall surface of the housing are continuous means that there is no step at the position where the taper surface and the outer wall surface of the housing are abutted, and that both tangents are substantially parallel.

  The pouring tap according to the present invention has the following effects.

  A gap between the inner peripheral surface of the outlet and the outer peripheral surface of the valve portion that is in surface contact is closed by a protrusion, and the outlet can be completely closed by the valve body. Does not cause dripping from the liquid. The height of the ridge is low enough not to release the surface contact between the two and is in a linear contact, so that the sealing is surely performed and the operation of the valve element is not heavy when opening and closing.

  Since the ridge is located in the center of the inner peripheral surface of the outlet when the valve body is closed, even if the relative position between the ridge and the outlet is displaced due to an error in the length of the valve body, etc. Thus, the ridge can always be brought into contact with the inner peripheral surface of the outlet to reliably close the outlet.

  Since the lower part of the valve part is formed in a taper shape, the content liquid adhering to the outer surface of the valve body collects at the lower end of the valve part and drops from the tip. Therefore, the solid content of the dried content liquid does not adhere to the surface of the valve body.

  In addition, when the content liquid adhering to the surface of the valve body gathers in one place, it was noted that when the collected amount reached the amount of one drop, it dropped as a drop and did not remain on the surface of the valve body . The ridge pushes out the content liquid between the inner peripheral surface of the outlet and the outer peripheral surface of the valve portion to the outside of the outlet when the valve body is inserted into the outlet. The extruded content liquid can be added to form one drop. The amount of the content liquid pushed out from the outlet by the valve body is calculated from the diameter of the outlet, the amount of movement of the ridge, and the gap gap, and the total amount of the content liquid collected at the top of the valve body is one drop, or Since the content liquid is dropped from the tip of the valve portion as an integral multiple thereof, the content liquid does not remain on the surface of the valve body.

  When the outlet is closed, the taper surface of the valve part is continuous with the outer wall surface of the housing, so the appearance is good, and when the outlet is completely closed, the taper surface of the valve body and the outer wall surface of the housing are continuous. It can be immediately judged from the appearance of the valve body and the housing that the stopper is completely closed.

  Hereinafter, an embodiment of a spout according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the spout 1 includes a resin housing 2, a valve body 4 provided in the housing 2, a handle 6 as an operating means screwed onto the upper portion of the housing 2, and the like. The screw cap 48 is attached to the discharge port 52 of the container 50.

  The container 50 is a resin storage container for storing content liquids such as seasonings and liquor, and may be easily deformable or hard and not easily deformed, and is integrally attached to the lower wall surface by welding or the like. The discharge port 52 is provided.

  The housing 2 has a vertical cylindrical shape and is open at the top. As shown in FIG. 3, a pair of engaging pieces 13 having different widths are formed on the upper outer peripheral surface so as to face each other. Further, as shown in FIG. 3, a pair of engaging end faces 32 that are cut substantially perpendicularly from the upper end faces are formed on the upper end faces at positions facing each other across the center.

  An inflow port 5 is formed on the lower side surface of the housing 2, and the attachment port 7 following the inflow port 5 is fitted into the discharge port 52 of the container 50 and fastened with a screw cap 48 attached to the outside thereof. 50 is detachably fixed. A second projecting piece 35 is provided on the side wall of the mounting port 7 facing the housing 2.

  As shown in FIGS. 1 and 4, an outlet 8 that fits the valve portion 9 of the valve body 4 is opened downward at the lower end of the housing 2. Further, an outlet is provided outside the outlet 8. A lid 22 covering 8 is attached so as to be openable and closable.

  The lid 22 is connected to a ring-shaped attachment ring 24 fitted to the housing 2 via a hinge 11 as an opening / closing mechanism, and is integrally formed by injection molding including the hinge 11. The mounting ring 24 is rotatably fitted in a circumferential groove 25 formed on the lower outer periphery of the housing 2. When the lid body 22 is opened, the lid body 22 is held open by the engaging protrusions 26 formed on both sides of the hinge 11. The lid 22 is held in the closed state by the stop projection piece 27.

  As shown in FIG. 2, the valve body 4 is cylindrical and includes a handle portion 23 at the upper portion and a valve portion 9 at the lower portion. The handle portion 23 is centered on the inside of a support body 28 provided on the handle 6. Are fixed and fitted. The valve portion 9 includes an inclined surface that extends downward, a protrusion 12 that protrudes laterally at the lower end of the inclined surface, a cylindrical tube portion 20 that extends below the protrusion 12, and a lower portion of the tube portion 20. It is formed from a conical bottom 3 or the like. Further, a stable arm 10 extending to the front of the inner surface of the housing 2 is provided above the valve portion 9 so as to protrude in four directions.

  The projecting portion 12 is formed in a circumferential shape in a state of projecting sideways at the upper end of the cylindrical portion 20, and the outer periphery is larger than the inner diameter of the outlet 8, so that the valve body 4 does not escape from the outlet 8. .

  On the outer peripheral surface of the cylindrical portion 20, a protrusion 21 protruding outward is provided in a circumferential shape. The height of the protrusion 21 is slightly higher than the gap between the cylindrical portion 20 and the outlet 8, and when the cylindrical portion 20 is inserted into the outlet 8, the surface contact between the cylindrical portion 20 and the outlet 8 is not released. , And contacts the inner peripheral surface of the outlet 8 over the entire circumference. Further, the protrusion 21 is located at the center of the inner peripheral surface of the outlet 8 in a state where the valve body 4 closes the outlet 8.

  The bottom portion 3 has a conical shape having a right apex angle, and is tapered from the lower end of the cylindrical portion 20 in a tapered shape. The periphery of the bottom 3 is smoothly continuous with the outer wall surface of the housing 2 in a state where the valve body 4 closes the outlet 8.

  As shown in FIG. 5, the handle 6 has a disc-like gripping plate 14 with a protruding piece 16 projecting in one direction and an unevenness formed on the outer peripheral surface for gripping, and a handle 6 attached below the gripping plate 14. A cylindrical outer cylinder 15 and a support 28 are formed.

  The outer cylinder 15 is slidably fitted on the outer surface of the housing 2, and the groove 18 that is screwed into the engagement piece 13 is formed in a spiral shape on the inner surface in accordance with the width of the engagement piece 13. . Further, a first protrusion 34 is provided on the outer peripheral surface of the outer cylinder 15 so as to contact the second protrusion 35 so as not to get over. When the handle 6 is tightened, the first projecting piece 34 and the second projecting piece 35 get over each other when the handle 6 is rotated and the handle 6 is rotated, and when the handle 6 is rotated from the tightened state by a predetermined angle in the opening direction. Abutting impossible.

  As shown in FIG. 1, the support 28 is formed on the sealing material 17 having a thin wall at the lower end, and the lower end slightly expands outwardly so as to contact the inner surface of the housing 2 closely and slidably. The inside of 2 is sealed in a liquid-tight manner. In addition, since the handle 6 and the sealing material 17 are made of the same material, the sealing material 17 is made elastic so that the strength of the handle 6 is ensured.

  Further, a triangular trapezoidal locking piece 33 is provided between the outer cylinder 15 and the support 28 so as to correspond to the locking end surface 32 and downward as shown in FIG. When the handle 6 is rotated in the closing direction, the locking piece 33 comes into contact with the locking end surface 32 when the valve body 4 closes the outlet 8 and stops the handle 6 from rotating in the closing direction.

  Next, the usage of the pouring tap 1 will be described.

  First, the attachment port 7 is assembled to the discharge port 52 of the container 50, and the screw cap 48 is screwed to fix the spout 1 to the container 50. Then, the content liquid in the container 50 flows into the pouring tap 1 through the inflow port 5. The valve body 4 is fitted to the outlet 8, and the content liquid does not flow out from the outlet 8.

  When the content liquid is poured out, the lid 22 is bent by the hinge mechanism 11 and the lower part of the housing 2 is opened. The lid 22 is held in an open state as shown in FIG. When the handle 6 is rotated in the opening direction, the handle 6 is moved upward by screwing, and the valve body 4 integrally attached to the handle 6 is raised in the housing 2 as shown in FIG. Opened.

  When the handle 6 is rotated to a predetermined angle, the first projecting piece 34 and the second projecting piece 35 come into contact with each other. Since the rotation of the handle 6 is stopped at that time, the handle 6 can be prevented from coming off, and an appropriate opening degree is obtained, and the content liquid is poured out from the container 50 through the outlet 8 at an appropriate outflow speed. . Moreover, since the valve part 9 is cylindrical and the bottom part 3 is conical, the outflow port 8 is evenly opened, and the content liquid flows down along the shape of the bottom part 3, so that there is no scattering to the surroundings. Leaked.

  The first projecting piece 34 and the second projecting piece 35 may be set so as to be able to get over in the opening direction of the handle 6. Then, it becomes possible to disassemble the spout 1 by turning in the opening direction.

  When a desired amount of content liquid is poured out of the container 50, the handle 6 is rotated in the closing direction. When the handle 6 is rotated to the closed position of the outlet 8, the locking piece 33 comes into contact with the locking end surface 32 to stop the rotation of the handle 6, and the valve body 4 closes the outlet 8 and the contents from the container 50. Liquid outflow is stopped.

  At that time, since the protrusion 21 is in close contact with the inner peripheral surface of the outlet 8, the outflow of the content liquid is surely stopped. Further, since the bottom 3 of the valve portion 9 is formed in a conical shape, the content liquid adhering to the bottom 3 flows down along the surface of the bottom 3 and concentrates at the tip and falls as a drop.

  Further, the protrusion 21 scrapes off the liquid content between the inner peripheral surface of the outlet 8 and the cylindrical portion 20 and pushes it out from the outlet 8. The amount of the content liquid to be pushed out can be calculated from the gap between the valve portion 9 and the outlet 8, the distance that the protrusion 21 moves while contacting the inner peripheral surface of the outlet 8, and the inner diameter of the valve portion 9, Since the total amount of the content liquid adhering to the outer surface of the valve portion 9 is set to be one drop or an integral multiple thereof, the content liquid drops from the tip of the valve portion 9. All fall and no liquid remains on the surface of the bottom 3. Therefore, the content liquid remaining on the surface is dried, and the solid content is not generated in the valve portion 9.

  Further, when the valve body 4 does not completely close the outlet 8, the peripheral edge of the bottom portion 3 and the outer wall surface of the housing 2 are not continuous, and a step is generated there, so that the valve body 9 is not completely closed. This can be immediately recognized from the appearance of the spout 1.

  In addition, although the protrusion 21 was formed in the outer peripheral surface of the valve part 9, the outer surface of the valve part 9 is made into a mere cylindrical body, and the protrusion 21 which protrudes inward of an inner peripheral surface on the inner peripheral surface of the outflow port 8 is provided. It may be provided. In this case, even if the valve portion 9 is inserted into the outlet 8, the content liquid adhering to the outer surface of the valve portion 9 is scraped by the ridge 21 and pushed into the housing 2. 8 does not flow out.

  When the dispensing of the content liquid is stopped, the lid 22 is rotated to cover the outside of the outlet 8. The lid 22 is kept closed by the locking protrusions 27 and can prevent dust and insects from adhering to the bottom 3 of the valve body 9 and the vicinity of the outlet 8.

  Thus, when the said spout 1 closes the outflow port 8, since the protrusion 21 closes between the valve part 9 and the outflow port 8 in the state holding the surface contact of the valve unit 9 and the outflow port 8, The outflow of the content liquid from the outflow port 8 can be stopped reliably, and liquid dripping does not occur. Since the protrusion 21 is basically located at the center of the inner peripheral surface of the outlet 8, the protrusion 21 is brought into contact with the inner peripheral surface of the outlet 8 even if there is a variation in temperature or variation in molding accuracy of each part. Can be closed securely.

  Since the bottom 3 is formed in a conical shape, the content liquid flows out smoothly when the outlet 8 is opened. Further, since the bottom portion 3 is formed in a conical shape facing downward, the content liquid adhering to the surface of the rear bottom portion 3 that stops the outflow from the outlet 8 flows down along the bottom portion 3, and the bottom portion of the bottom portion 3. Drops from the tip as a drop. Therefore, the content liquid does not remain on the surface of the bottom portion 3, and the dried solid material from the content liquid does not adhere to the periphery of the outlet 8.

  Further, since the locking end surface 32 and the locking piece 33 abut against each other and the rotation of the handle 6 in the closing direction is stopped, excessive rotation of the handle 6 in the closing direction can be prevented. Even if the handle 6 is forcibly rotated, the protrusion 12 does not hit the inner edge of the outlet 8 and the valve body 4 does not come out.

  Further, when the handle 6 is rotated in the opening direction, the first projecting piece 34 and the second projecting piece 35 come into contact with each other at a predetermined rotation angle, and the rotation is stopped. The content liquid can be poured out from the container 50 at an appropriate flow rate at the time.
