Description

  The present invention relates to a cap having a lid.

  Conventionally, as this type of cap, for example, as shown in FIGS. 12 and 13, a cap main body 72 attached to the mouth of the container 71 and a lid provided on the cap main body 72 through a hinge 73 so as to be freely opened and closed. Some have a body 74. The cap body 72 is provided with a pour cylinder 75 protruding in a cylindrical shape, and the pour cylinder 75 has a spout 76 at the tip.

  A cylindrical inner ring 77 is provided inside the lid 74. As shown in FIG. 12, when the lid 74 is closed, the inner ring 77 is inserted into the spout 76, and the outer peripheral surface of the inner ring 77 is in close contact with the inner peripheral surface of the dispensing cylinder 75. Thereby, the fluid in the container 71 is prevented from leaking from between the inner ring 77 and the dispensing cylinder 75 to the outside.

  The cap as described above is described in, for example, Patent Document 1 below.

JP 2009-113831

  However, in the above conventional type, the inner ring 77 is provided on the lid 74, so that the recess 78 is formed inside the lid 74. When the fluid in the container 71 is a highly viscous liquid W, when the container 71 is shaken, the liquid W in the container 71 accumulates in the recess 78 of the inner ring 77 as shown by the phantom line in FIG. There is a problem that the liquid W remains in the recess 78 for a long period of time, which is not preferable for hygiene.

Further, when the lid 74 is opened and the liquid W in the container 71 is poured out from the spout 76, there is a problem that the liquid W accumulated in the recess 78 flows down and soils the cap body 72.
An object of this invention is to provide the cap which has a structure where the fluid in a container does not accumulate easily inside a cover body.

In order to achieve the above object, the cap according to the first invention has a cap body attached to the mouth of the container, and a lid body detachably provided on the cap body.
The cap body is provided with a protruding dispensing cylinder,
The dispensing cylinder has a spout at the tip,
A distribution port communicating with the inside of the container and the outlet is formed at the bottom of the outlet cylinder,
The lid has a protrusion on the inside that opens and closes the spout,
With the lid closed, the protrusion is fitted into the spout, the outer peripheral surface of the protrusion contacts the inner peripheral surface of the spout,
The inner surface of the protrusion that faces the circulation port in a state where the lid is closed is a flat surface on which no recess is formed.

  According to this, when the lid is attached to the cap body and closed, the protrusion of the lid is fitted into the spout, and the outer peripheral surface of the protrusion contacts the inner peripheral surface of the spout. As a result, the spout is closed, the gap between the protrusion and the extraction cylinder is sealed, and the fluid in the container can be prevented from leaking from between the protrusion and the extraction cylinder. .

Moreover, since the inner surface of the protrusion is a flat surface on which no recess is formed, there is an effect that the fluid in the container is less likely to accumulate inside the lid.
In the cap according to the second aspect of the invention, the cap main body and the lid are provided with engaging portions that engage with each other with the lid closed.
With the cover body moving in the opening direction for a minimum movement distance that the engagement part on the lid side is detached from the engagement part on the cap body side, the outer peripheral surface of the protrusion is separated from the inner peripheral surface of the spout, A gap communicating with both the inside and outside of the dispensing cylinder is generated between the protrusion and the tip of the dispensing cylinder.

According to this, when the lid is closed, the engaging portion on the lid body side is engaged with the engaging portion on the cap body side, so that the lid body can be prevented from being opened carelessly.
Further, when the container is shaken with the lid closed, there is a concern that a closed state in which the fluid in the container adheres to the inner surface of the protrusion and closes the spout temporarily occurs. Even if such a closed state occurs, when the lid is opened from the closed position, when the lid moves in the opening direction by the minimum movement distance, the outer peripheral surface of the protrusion is A gap that is spaced from the inner peripheral surface of the spout and communicates both inside and outside the spout tube is generated between the protrusion and the tip of the spout tube, so external air is immediately poured through the gap. It flows into the inside of the cylinder and the inside of the dispensing cylinder is opened to the atmosphere.

  As a result, the fluid that has closed the spout is peeled off from the inner surface of the protrusion by atmospheric pressure and falls in the spout cylinder, so when the lid is opened by the minimum moving distance, quickly, The closed state of the spout due to the fluid can be eliminated.

In the cap according to the third aspect of the present invention, a receiving member for receiving a fluid on the inner surface of the protrusion when the lid is opened is provided on the protrusion.
According to this, even when the fluid flows along the inner surface of the protrusion when the lid is opened, the fluid is received by the receiving member. For this reason, it can prevent that a fluid flows down and soils a cap main body.

  In the cap according to the fourth aspect of the invention, the protrusion and the receiving member are fitted into the spout with the lid closed, and the outer peripheral surface of the protrusion and the outer peripheral surface of the receiving member are on the inner peripheral surface of the spout. Abut.

  According to this, when the lid is closed, the protrusion of the lid and the receiving member are fitted into the spout, and the outer peripheral surface of the protrusion and the outer peripheral surface of the receiving member abut against the inner peripheral surface of the spout. As a result, the spout is closed, the space between the protrusion and the spout tube and the space between the receiving member and the spout tube are sealed, and the fluid in the container can be prevented from leaking to the outside. .

In the cap according to the fifth aspect of the present invention, a recess is formed on the outer surface opposite to the inner surface of the protrusion of the lid.
According to this, since the thickness of the portion where the protrusion of the lid is formed is reduced by the formation of the recess, the lid is reduced in weight, and the lid can be easily opened and closed.

  In the cap according to the sixth aspect of the present invention, the lid is provided on the cap body via the hinge portion.

  As described above, according to the present invention, since the inner surface of the protrusion is a flat surface on which no recess is formed, an effect is obtained that the fluid in the container is less likely to accumulate inside the lid. Thereby, it can prevent that a fluid accumulates inside a cover body for a long period of time, and it improves in terms of hygiene. Further, when the lid is opened by the minimum moving distance, the closed state of the spout due to the fluid can be quickly eliminated. Further, it is possible to prevent the fluid from flowing down and soiling the cap body. Also, the lid is lighter and the lid can be easily opened and closed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
In the first embodiment, as shown in FIGS. 1 to 3, 1 is a cap attached to the container 2, and the cap 1 includes a cap body 4 attached to the mouth 3 of the container 2, and a hinge part. 5 and a cap body 6 provided on the cap body 4 via the cap body 4.

  The cap body 4 has a cylindrical body portion 8 and a top plate portion 9 provided at the top end of the body portion 8. The body portion 8 is formed with an insertion portion 12 that is open at the bottom, and the mouth portion 3 of the container 2 is inserted into the insertion portion 12 and attached thereto. Further, the top plate portion 9 is provided with a cylindrical pouring tube 13 projecting upward and an annular projecting piece portion 14. The extraction tube 13 has a circular outlet 15 and a lip 16 at the tip.

  A flow port 19 that communicates with the inside of the container 2 and the spout 15 is formed at the bottom of the pour tube 13. In the unused state where the cap 1 is not opened, the circulation port 19 is closed by a closing wall 21 having a pull ring 20 as indicated by a virtual line in FIG. When the highly viscous liquid W (an example of a fluid) in the container 2 is poured out, the lid 6 is opened, the pull ring 20 is pulled, and the closing wall 21 is torn off, thereby opening the circulation port 19.

  The projecting piece 14 is erected on the radially outer side of the extraction tube 13, and an engagement recess 23 (an engagement portion on the cap body side) that is recessed radially inward is formed on the outer peripheral surface of the projecting piece 14. An example) is formed over the entire circumference. Further, the lip portion 16 is formed so as to expand radially outward from the tip end portion of the dispensing cylinder 13.

  The lid body 6 includes a circular lid plate portion 27 and a peripheral wall portion 28 provided on the periphery of the lid plate portion 27. On the inner peripheral surface on the opening side of the peripheral wall portion 28, an engaging convex portion 29 (an example of an engaging portion on the lid side) protruding radially inward is formed over the entire circumference. The engagement convex part 29 can be freely engaged with and disengaged from the engagement concave part 23 in the opening / closing directions O and S (vertical direction) of the lid body 6, and the lid body 6 is closed as shown in FIGS. In the state, the engaging convex portion 29 engages with the engaging concave portion 23, and the engaging convex portion 29 is disengaged from the engaging concave portion 23 in the state where the lid body 6 is opened as shown in FIGS. break away. 5 and 6B, when the lid 6 is opened from the closed state, the minimum moving distance of the lid 6 required for the engagement convex portion 29 to be detached from the engagement concave portion 23 is shown. Is defined as the minimum moving distance A.

  The lid 6 has a circular protrusion 32 that opens and closes the spout 15 on the inner side. The protrusion 32 is formed on the inner surface of the lid plate portion 27. As shown in FIGS. 1 and 4A, the protrusion 32 is fitted into the spout 15 with the lid 6 closed. The outer peripheral surface of the protrusion 32 is in close contact with the inner peripheral surface of the spout 15 over the entire periphery. An inner surface 32a of the protrusion 32 that faces the flow port 19 in a state where the lid 6 is closed is a flat surface on which no recess is formed.

  4A, the length of the region where the outer peripheral surface of the protrusion 32 is in close contact with the inner peripheral surface of the spout 15 in the opening / closing directions O and S of the lid 6 (in the axial direction of the cap 1). Assuming that the length is the seal length B, the value of the seal length B is set to be larger than 0 and not more than the value of the minimum moving distance A (see FIG. 6B).

  An annular small protrusion 34 is formed on the inner surface of the lid plate portion 27. The small projecting portion 34 is on the radially outer side of the projecting portion 32, and is in close contact with the tip end portion of the lip portion 16 over the entire circumference in a state where the lid body 6 is closed as shown in FIGS. Further, a concave portion 35 that is recessed inward is formed on the outer surface of the protrusion 32 of the lid body 6 opposite to the inner surface 32a.

Hereinafter, the operation of the above configuration will be described.
As shown in FIGS. 1 and 4, when the lid body 6 is closed, the protrusion 32 of the lid body 6 is fitted into the spout 15, and the outer peripheral surface of the protrusion 32 is entirely surrounded by the inner peripheral surface of the spout 15. Close over. Thereby, the spout 15 is closed, the gap between the protrusion 32 and the extraction cylinder 13 is sealed, and the liquid W in the container 2 leaks from between the protrusion 32 and the extraction cylinder 13 to the outside. Can be prevented.

  Moreover, since the inner surface 32a of the protrusion 32 is a flat surface on which no recess is formed, the liquid W in the container 2 can be prevented from accumulating inside the lid body 6. Thereby, the liquid W in the container 2 does not accumulate inside the lid body 6 for a long period of time, which improves hygiene.

Further, when the lid body 6 is closed as shown in FIG. 1, the engagement protrusion 29 engages with the engagement recess 23 as shown in FIG. Can be prevented.
Further, when the container 2 is shaken with the lid 6 closed, as shown in FIG. 7, the liquid W in the container 2 adheres to the inner surface 32 a of the protrusion 32 and closes the spout 15. There is a concern that this may occur temporarily. Even if such a closed state occurs, when the lid 6 is opened from the closed position C, as shown in FIGS. 5 and 6, the minimum moving distance A (the engagement portion on the lid side is the cap body). When the lid body 6 moves in the opening direction O by an amount corresponding to the minimum movement distance that is disengaged from the engagement portion on the side, the outer peripheral surface of the protrusion 32 is separated from the inner peripheral surface of the spout 15 and is poured out. Since a gap 37 communicating with both the inside and the outside of the cylinder 13 is generated between the protrusion 32 and the lip portion 16 (the tip of the extraction cylinder), external air immediately passes through the gap 37 in the extraction cylinder 13. It flows into the inside, and the inside of the extraction tube 13 is opened to the atmosphere.

  As a result, the liquid W (see FIG. 7) that has closed the spout 15 is peeled off from the inner surface 32a of the protrusion 32 by atmospheric pressure and falls in the spout cylinder 13, so that the lid 6 is moved to the minimum moving distance. When only A is opened, the closing state of the spout 15 by the liquid W can be quickly eliminated.

  Further, as shown in FIG. 1, since the concave portion 35 is formed in the lid body 6, the thickness T of the portion of the lid body 6 where the protrusions 32 are formed is reduced. Thus, the lid 6 can be easily opened and closed.

  Further, by manufacturing the cap 1 with a raw material containing a lubricant, the liquid W adhering to the inner surface 32a of the protrusion 32 can be repelled, and the inner surface 32a of the protrusion 32 can be prevented from being contaminated with the liquid W. Can do.

(Second Embodiment)
