Description

  The present invention relates to a cap for a container and a container with a cap, and more particularly, to a cap and a container with a cap capable of selecting the number of discharge ports for contents.

  2. Description of the Related Art Conventionally, as a cap of a flexible container filled with viscous contents such as mayonnaise, an integrated hinge cap made of a synthetic resin in which a canopy portion is integrally connected by a hinge is employed. A discharge port is formed in such a cap, and since the content is discharged from the discharge port, the discharge amount and the discharge shape are constant. As a result, it is possible to select two types of usage, such as drawing and using a discharge line from the discharge port, or removing and directly squeezing the cap to use.

  In recent years, demands on how to use caps have been diversified. For example, when applying mayonnaise or sauce to takoyaki or okonomiyaki, it is difficult to make the discharge intervals uniform with one discharge port, and it takes time and the workability is poor. Therefore, a cap provided with a plurality of discharge ports is desirable.

  As a cap capable of selecting a discharge port, for example, a cap disclosed in Patent Document 1 is known. Patent Literature 1 relates to a sealing cap in which a lid portion that opens each of the outlets for the contents is provided in two layers, and the outlets of the outlets have different diameters. Three frontal caps are described.

  In the cap disclosed as the second embodiment in Patent Literature 1, it is possible to change the discharge amount and the number of discharge ports by overlapping the cover plate portion, the middle cover portion, and the upper cover portion. Three usages are possible. In other words, the method of removing and directly squeezing the cap and using it, the method of using the cap attached to the container opening by overlapping the upper lid and the inner lid, opening from the lid plate, discharging from a plurality of outlets, and using the container In the cap attached to the mouth, the inner lid portion and the lid plate portion are overlapped, opened from the upper lid portion, and discharged only from the discharge port where the outlet of the inner lid portion and the outlet of the lid plate portion overlap, It is. According to such a structure, it is possible to easily select the discharge port of the contents without performing the work of replacing the cap.

  However, as in the case of the cap described in Patent Literature 1, when the discharge port of the lid plate is overlapped with the tip of the discharge port of the middle lid, and these are communicated to discharge the contents, the lid plate There is a possibility that the contents remaining at the tip of the discharge port may adhere to the back surface of the inner lid. In addition, the contents may leak out from the gap between the tip of the discharge port of the inner lid and the lid plate, and may remain in the space between the inner lid and the lid plate. The contents that adhere to the back surface of the inner lid portion or remain in the space are covered with the inner lid portion, so that it is difficult to see from the outside and is left as it is, causing invisible dirt. . In addition, if the inner lid is opened without noticing this, the residual contents may be inadvertently attached to the hand or the like.

  An object of the present invention is to solve the above-described problems. Specifically, the number of discharge ports can be selected, and a cap and a container with a cap that do not adhere to and remain on the inner lid or the like. It is an object to provide

  According to the present invention, in order to solve the above-mentioned problems, a skirt portion attached to a container neck portion, a lid plate portion covering an upper end of the skirt portion, a lid plate portion and a first hinge are provided. And a top lid connected to the middle lid and the second lid via a second hinge, wherein the lid plate portion is a cylindrical second member standing upright from the lid plate portion. A first discharge port and a second discharge port, wherein the inner lid portion includes a through hole having an inner diameter larger than an outer diameter of a distal end of the discharge port in the first discharge port; When the is closed, the tip of the first discharge port protrudes from the through hole.

  In the cap having this configuration, the first discharge port has a tip protruding outward from the through hole provided in the inner lid, so that the first discharge port can be used even when the lid plate and the inner lid are used in an overlapping manner. The inner lid does not come into contact with the contents. Therefore, it is possible to reliably prevent the contents from adhering to the inner lid portion.

Further, the second discharge port is a cylindrical discharge port having a lower height than the first discharge port .

  In the cap with this configuration, the discharge ports in the lid plate are all cylindrical, and when the container is returned to the original standing state after discharge, the contents in the cap leak from the cylindrical discharge port to the lid plate. It is returned into the container without doing. Therefore, it is possible to prevent the contents from hanging on the lid plate.

  Further, the first hinge and the second hinge may be arranged on opposite sides of the first discharge port.

  In the cap having this configuration, since the first hinge and the second hinge are located on opposite sides of the first discharge port, there is a possibility that the inner lid may be opened by mistake when only the upper lid is opened. There is no.

  Further, the first discharge port and the through hole may be in contact with each other on the first hinge side, and may have a gap on the second hinge side.

  In the cap with this configuration, even if the contents remain at the tip of the discharge port of the first discharge port after the discharge from the first discharge port, the inner lid section and the first lid section are opened and closed when the inner lid section is opened and closed. Since there is a gap on the second hinge side with respect to the discharge port, it is possible to prevent the contents from adhering to the inner lid. Also, in the case where the lid plate portion and the inner lid portion are overlapped and opened with the second hinge, even if the contents hang down from the first discharge port, the first discharge port is in the middle. Since it is in contact with the lid on the first hinge side, it can be received on the upper surface of the inner lid. Therefore, the dripping contents can be easily wiped off, and the cap is prevented from being soiled.

  Further, the second discharge port may be a cylindrical discharge port having substantially the same height as the first discharge port.

  In the cap having this configuration, the heights of the discharge ports are substantially the same, and when the contents are squeezed out, it is possible to discharge at the same timing.

  In addition, a container with a cap according to the present invention is characterized by including a container and the cap described in any of the above, in order to solve the above problems.

  ADVANTAGE OF THE INVENTION According to this invention, the number of discharge ports can be selected, and the cap and the container with a cap which do not adhere a content to an inner lid can be obtained.

The top plate portion 32 of the lid plate portion 3 has one first discharge port 8 which rises in a truncated cone shape from the top plate portion 32 and continuously extends on a cylinder from the top surface of the truncated cone. Two second outlets 9 having a lower column height than the outlet 8 are formed. Therefore, the number of the discharge ports in the cover plate portion 3 is three.

  As shown in FIG. 6, a circumferential projection 33 is provided on the rear surface of the lid plate portion 3, and functions as a suppression when an aluminum seal is attached to the mouth of the container body 100.

  The first hinge 4 is provided at the upper end of the second flat portion 23 and is integrally formed so as to connect the cover plate portion 3 and the middle cover portion 5 (FIGS. 2 and 6). The second flat portion 23 and the first flat portion 22 are located on opposite sides of the first discharge port 8.

  As shown in FIG. 5, the inner lid part 5 includes a peripheral part 51 connected to the first hinge 4, and a top plate part 52 that covers the upper end of the peripheral part 51. A concave portion 51a is formed on the back surface of the peripheral portion 51 so as to engage with a convex portion 31a protruding from the upright wall 31 of the cover plate portion 3 (FIG. 4). The top plate 52 is formed with an upright wall 53 that stands vertically from the periphery of the top plate 52, and the upright wall 53 has a projection 53 a that engages with a recess 71 a described later formed in the upper lid 7. Is protruded. The upright wall 53 is gently inclined toward the center of the top plate 52, and is flat at the center of the inner lid 5. A through hole 10 having an inner diameter larger than the outer diameter of the tip of the discharge port of the first discharge port 8 is formed in the top plate part 52 of the inner lid part 5. The through hole 10 is provided at a position facing the first discharge port 8 when the inner lid portion 5 is overlaid on the lid plate portion 3. The through hole 10 and the first discharge port 8 are in contact with each other on the first hinge 4 side of the through hole 10, and have a gap 11 on the second hinge 6 side. In addition, a sealing protrusion 54 for sealing the second discharge port 9 when the lid plate portion 3 and the inner lid portion 5 are overlapped is formed on the back surface of the top plate portion 52. (Fig. 6).

  The second hinge 6 is formed at the upper end of the peripheral edge 51 and is integrally formed so as to connect the inner lid 5 and the upper lid 7.

  As shown in FIGS. 2 and 5, the upper lid part 7 includes a peripheral part 71 connected to the second hinge 6, and a top plate part 72 that covers the upper end of the peripheral part 71. A concave portion 71a is formed on the rear surface of the peripheral edge portion 71 so as to engage with a convex portion 53a protruding from the upright wall 53 of the inner lid portion 5. A finger hook 73 is provided at the lower end of the peripheral edge 71 to protrude therefrom. The finger hook 73 is arranged above the first hinge 4 when the cover plate 3, the middle cover 5 and the upper cover 7 are overlapped. A sealing projection 74 that seals the first discharge port 8 when the cover plate 3, the middle cover 5, and the upper cover 7 are overlapped is formed on the back surface of the top plate 72.

  Next, a method of discharging the cap (a container with a cap) according to the present embodiment will be described. Three types of ejection are possible by the ejection method described later.

(Discharged from container mouth)
When discharging from the container mouth, as shown in FIG. 1, the cap 1 screwed to the mouth and neck of the container body 100 is removed by rotating in the opposite direction to the time when the cap is screwed. When the container body 100 is squeezed in this state, the contents are discharged according to the shape of the container mouth.

(Discharge from multiple discharge ports)
In the case of discharging from a plurality of discharge ports, in FIG. 2, with the upper lid portion 7 and the middle lid portion 5 being overlapped, a finger is pushed on the second hinge 6 and pushed upward. Then, as shown in FIG. 4, the inner lid portion 5 rotates about the first hinge 4, and the first discharge port 8 and the second discharge port 9 are exposed. At this time, the upper lid 7 is connected to the inner lid 5 via the second hinge 6, and a concave portion 71 a formed on the back surface of the peripheral edge 71 of the upper lid 7 and the upright wall of the inner lid 5. A projection 53a protruding from 53 is engaged. Therefore, the upper lid 7 and the inner lid 5 are integrally fixed.

  By providing the first flat portion 22 on the skirt portion 2 at the time of opening the lid, it becomes easier for the second hinge 6 to be touched by a finger, and it is possible to open it smoothly. Further, by making the shapes of the first flat portion 22 and the second flat portion 23 different from each other, the case where the first hinge 4 is rotated around the center and the case where the first flat portion 22 is rotated around the second hinge 6 are: It is easy to visually determine each of them.

  When the container body 100 is squeezed in this state, the contents are discharged from the first discharge port 8 and the second discharge port 9, and the contents are discharged from three places.

In addition, since the roots of the first discharge port 8 and the second discharge port 9 have a truncated cone shape, discharge is performed smoothly.
Further, by making the second discharge port 9 a cylindrical discharge port, all the discharge ports in the cover plate portion 3 become cylindrical. Thereby, when the container is returned to the original standing state after use, the contents in the cap do not leak from the first discharge port 8 and the second discharge port 9 to the cover plate portion 3, and the contents inside the container are removed. Is returned to. Therefore, it is possible to prevent the contents from hanging on the lid plate. Even if the contents hang down on the lid plate portion, the first discharge port 8 and the second discharge port 9 are provided on the flat top plate portion 32 of the lid plate portion 3, and thus hang down. Content can be easily wiped off, and good hygiene can be maintained. In addition, since the upright wall 31 is gently inclined toward the center of the cover plate portion 3, dirt can be prevented from collecting at the base of the upright wall 31.

  In addition, by providing the top plate portion 32 at a position lower than the top end of the upright wall 31, the size of the cap itself is kept small, and the length of the first discharge port 8 and the second discharge port 9 is reduced. Can be set longer.

  After discharging the desired amount, the inner lid portion 5 is turned in the opposite direction to the above to return to the original state. The concave portion 51a formed on the back surface of the peripheral portion 51 of the inner lid portion 5 and the convex portion 31a projecting from the upright wall 31 of the lid plate portion 3 are sealed by being engaged.

(Discharged only from the first discharge port 8)
In the case of discharging from only the first discharge port 8, in FIG. 2, a finger is put on the finger hook 73 and pushed upward. Then, as shown in FIG. 5, the upper lid part 7 rotates about the second hinge 6, and the first discharge port 8 is exposed.

  At this time, the inner lid portion 5 is connected to the lid plate portion 3 via the first hinge 4, and the concave portion 51 a formed on the back surface of the peripheral edge portion 51 of the inner lid portion 5, The projection 31a protruding from the wall 31 is engaged. Therefore, the inner lid part 5 and the lid plate part 3 are integrally fixed. In addition, since the first hinge 4 and the second hinge 6 are disposed on the opposite side of the inner lid 5 at 180 ° apart with the first discharge port 8 interposed therebetween, the finger hook 73 is pushed up. But they don't lift together.

  When the container body 100 is squeezed in this state, the contents are discharged from the first discharge port 8. At this time, as shown in FIG. 6, the second discharge port 9 is sealed by a sealing projection 54 formed on the back surface of the top plate 52 of the inner lid portion 5. There is no leakage of the contents. Therefore, it becomes possible to discharge the contents only from the first discharge port 8.

  The height of the cylinder at the first discharge port 8 may be set higher than the height of the peripheral edge 51 of the inner lid 5. If the height of the first discharge port 8 is lower than the height of the peripheral portion 51 of the inner lid portion 5, the discharge port does not protrude from the through hole 10 and adheres to the through hole 10 when discharging the contents. . Also. If the height of the first discharge port 8 is too high, the size of the cap itself becomes large, which is not preferable.

  The height of the cylinder at the second discharge port 9 may be lower than the height of the peripheral portion 51 of the inner lid 5, and the sealing formed on the front end of the discharge port and the back surface of the top plate 52 of the inner lid 5. The projection 54 is set so as to be in contact therewith.

  Since the first discharge port 8 protrudes from the through hole 10 of the inner lid 5, it is possible to prevent the discharge port (the through hole 10 of the present invention) of the inner lid 5 from coming into contact with the contents, and Objects can be prevented from remaining and causing contamination. In addition, since the contents do not remain in the through-hole 10, even when the upper lid 7 and the inner lid 5 are overlapped and the lid plate 3 is opened from the first hinge 4, the lid is opened. Sometimes, it can be prevented from getting stuck in the hand.

  In addition, since the first discharge port 8 and the through hole 10 have a gap on the second hinge 6 side, it is possible to more reliably prevent the first discharge port 8 and the through hole 10 from adhering when opening and closing the inner lid.

  Further, since the first discharge port 8 and the through hole 10 are in contact with each other on the first hinge 4 side, when the container is returned to the upright state after use, the contents hang down from the first discharge port 8 by any chance. Even if it comes out, it can be received on the upper surface of the inner lid portion 3. Therefore, the wiping operation can be easily performed, and the sanitary condition can be maintained satisfactorily.

Second Embodiment Next, a second embodiment will be described. This embodiment is similar to the first embodiment, and the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the first embodiment, the second discharge port 9 is a low cylindrical discharge port, and the upper surface of the top plate 52 of the inner lid 5 is configured to be flat. In the embodiment, as shown in FIGS. 7 and 8, the second discharge port 9 is a discharge port having substantially the same height as the first discharge port 8. By making the second discharge port 9 a discharge port having substantially the same height as the first discharge port 8, when discharging from a plurality of discharge ports, the heights of the discharge ports can be made uniform, and the same timing can be obtained. Can be ejected.

  However, when the second discharge port 9 is a discharge port having substantially the same height as the first discharge port 8, if the shape of the inner cover 5 is the same as that of the first embodiment, the inner cover 5 During opening and closing, the tip of the second discharge port 9 collides with the inner lid 5, and a smooth opening and closing operation cannot be performed.

  For this reason, in the present embodiment, the top plate portion 52 of the inner lid portion 5 is not a flat surface, but is a deformed top plate portion 55 in which a portion facing the second discharge port 9 of the inner lid portion 5 is raised. By forming the deformed top plate portion 55, a space capable of accommodating the tip of the second discharge port 9 is formed, and when the lid plate portion 3 and the inner lid portion 5 are overlapped, the second discharge port 9 is closed. The outlet 9 is housed in the deformed top plate 55, and the second discharge port 9 does not collide with the inner lid 5 when the inner lid 5 is opened and closed.

  The space formed by the deformed top plate 55 (the space capable of accommodating the tip of the second discharge port 9) is formed in consideration of the movement of the inner lid 5 when the inner lid 5 is opened and closed. There is a need to. For example, as shown in FIG. 9 (A), by expanding the length of the deformed top plate portion 55 along the rotation direction of the inner lid portion 5, it is possible to reliably prevent a collision during the opening / closing operation. is there. In addition, since the inner lid portion 5 rotates when it is opened and closed, the shape of the deformed top plate portion 55 can be curved in accordance with this, as shown in FIG. 9B.

  As described above, by forming the portion of the inner lid portion 5 facing the second discharge port 9 as the deformed top plate section 55, the second discharge port 9 is formed at a discharge height substantially equal to that of the first discharge port 8. Even in the case of an outlet, the discharge from only the first discharge port 8 and the discharge from both the first discharge port 8 and the second discharge port 9 are selected by opening and closing the inner lid portion 5. Can be.

  When discharging from only the first discharge port 8, the second discharge port 9 is housed in the deformed top plate portion 55 and is closed, but at this time, careless leakage is eliminated. To this end, it is preferable to provide a sealing projection 54 at a portion of the deformed top plate 55 facing the tip of the second discharge port 9. For example, if the sealing projection 54 is formed as a spherical projection, the sealing projection 54 can reliably block the tip of the spherical second circular discharge port 9 and minimize leakage of contents. Can be minimized.

  Although the embodiment of the present invention has been described above, the embodiment of the present invention is not limited to the above. For example, the number, shape, arrangement, and the like of the discharge ports can be appropriately selected as needed.
