JP 2002-347813 A

However, in the conventional discharge cap, even when the slit is in an expanded state, a large content may be clogged in the slit, and there is room for improvement in smoothly discharging the content.
When the contents are clogged in the slit in this way, if the elastic film part is further elastically deformed in order to discharge the contents, for example, the elastic film part is moved from the edge of the slit to the extending direction of the slit. There is a risk that a tear extending outward may be formed. In this case, for example, there is a problem that the liquid drainage of the contents deteriorates.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a discharge cap that can easily discharge the contents smoothly.

In order to solve the above problems, the present invention proposes the following means.
The discharge cap according to the present invention is attached to a mouth portion of a container main body in which contents are accommodated, a mounting member provided with a communication hole communicating with the inside of the container main body, and a fixing member fixed to the mounting member. A discharge member that closes the communication hole, and the discharge member includes an elastic film portion that is disposed outside the container body with respect to the communication hole and has a slit formed therein. A discharge cap that opens the communication hole by elastically deforming the elastic film portion toward the outside of the container body so as to expand the slit as the internal pressure of the container body increases. The communication hole is provided with a crushing portion for crushing the contents passing through the communication hole.

  According to this invention, since the crushing portion is disposed in the communication hole, the contents passing through the communication hole can be crushed to reduce the size of the contents, and the slit is expanded. It is possible to suppress clogging of the content discharged from the inside of the slit and facilitate the smooth discharge of the content.

  Further, the crushing part may be separated from the elastic film part.

  In this case, since the crushing part is separated from the elastic film part, the contents are not allowed to reach the elastic film part immediately after starting to be crushed by the crushing part, but after being started to be crushed by the crushing part, The elastic film portion can be reached after passing through the space between the elastic film portion and the elastic film portion. Therefore, even if the contents are large, it is possible to continue to be crushed by the crushing part while passing through the separated space from when the contents start to be crushed by the crushing part until reaching the elastic membrane part. The object can be effectively crushed by the crushing part, and the clogging of the contents into the slit can be reliably suppressed.

  The crushing portion is provided with a rod-shaped portion disposed in the communication hole and having an end connected to the inner peripheral surface of the communication hole. The rod-shaped portion is directed toward the inside of the container body. A sharpened point may be formed.

In this case, the contents passing through the communication hole are crushed by contacting the rod-shaped portion from the inside of the container body.
Here, since the rod-shaped portion is formed with a sharpened portion that protrudes toward the inside of the container body, the contents can be effectively crushed by the crushing portion, and the contents can be discharged more smoothly. Can be made easier.

  With the discharge cap according to the present invention, the contents can be easily discharged smoothly.

A direction orthogonal to the cap axis O is referred to as a radial direction, and a direction around the cap axis O is referred to as a circumferential direction.

  The main body 34 is formed in a three-stage cylindrical shape in which a large-diameter portion 35, a medium-diameter portion 36, and a small-diameter portion 37 are connected in this order from the bottom to the top. The large diameter part 35, the medium diameter part 36, and the small diameter part 37 are integrally formed. The large-diameter portion 35 is formed in a double cylinder shape and is externally attached to the mouth portion 21 of the container body 20. The medium diameter portion 36 has a smaller diameter than the mouth portion 21. The connecting step portion that connects the large diameter portion 35 and the medium diameter portion 36 is located above the opening edge of the mouth portion 21, and the connecting step portion is in contact with the opening edge over the entire circumference. A seal member 34a is formed. The seal member 34 a blocks communication between the inside of the mouth portion 21 and the inside of the large diameter portion 35.

  An annular fixing portion 38 disposed coaxially with the cap shaft O is fitted in the middle diameter portion 36. The inside of the fixing portion 38 is a communication hole 39 that communicates with the inside of the container body 20. The communication hole 39 is arranged coaxially with the cap axis O. The fixed portion 38 is formed with an annular ridge 38 a that is disposed coaxially with the cap shaft O. The protruding portion 38a protrudes upward from the fixed portion 38.

On the lower surface of the flange portion 42, an annular concave groove portion 42a into which the protruding portion 38a is fitted is formed. The elastic cylinder portion 41 is disposed in the small diameter portion 37, and an annular gap is provided between the outer peripheral surface of the elastic cylinder portion 41 and the inner peripheral surface of the small diameter portion 37. The position of the upper end of the elastic cylinder part 41 in the cap axis O direction and the position of the upper end of the small diameter part 37 (the upper end of the main body part 34) in the cap axis O direction are equal to each other.

  The elastic film part 40 is located on the cap shaft O and located above the communication hole 39, and faces the communication hole 39 in the direction of the cap shaft O. The elastic film part 40 has a concave spherical shape that is concave downward. As shown in FIG. 2, slits 43 are formed in the elastic film portion 40. In the illustrated example, the slit 43 has an X shape (cross shape).

  As shown in FIG. 1, a bulging portion 33 a that bulges downward is formed on the top wall portion of the overcap 33. The bulging portion 33a bulges in a dome shape or hemispherical shape that protrudes downward. The bulging part 33a presses the elastic film part 40 from above, and elastically deforms the elastic film part 40 downward. The bulging part 33a is closed while expanding the slit 43 by elastically deforming the elastic film part 40 downward, and in the circumferential direction defined by the slit 43 in the elastic film part 40. Adjacent portions are prevented from sticking to each other.

  In the present embodiment, the communication hole 39 is provided with a crushing portion 44 that crushes the contents passing through the communication hole 39. The crushing portion 44 does not protrude outward from the fixed portion 38 in the direction of the cap axis O, and the entire crushing portion 44 is disposed in the communication hole 39 (inside the fixed portion 38). The crushing part 44 is separated from the elastic film part 40. The crushing part 44 faces the elastic film part 40 in the cap axis O direction and is located below the elastic film part 40, and extends between the elastic film part 40 and the crushing part 44 in the cap axis O direction. An existing separation space 45 is provided. The separation space 45 is provided in the elastic cylinder portion 41.

  As shown in FIG. 3, the crushing portion 44 includes a rod-like portion 46 that is disposed in the communication hole 39 and has an end portion connected to the inner peripheral surface of the communication hole 39. A plurality of rod-like portions 46 are provided with the same position in the direction of the cap axis O, and these rod-like portions 46 have the cap axis O in a plan view when the discharge cap 30 is viewed from the cap axis O direction. They are arranged point-symmetrically as a reference. The rod-shaped portion 46 protrudes from the inner peripheral surface of the communication hole 39 into the communication hole 39, and in the illustrated example, protrudes toward the inside in the radial direction. A plurality of rod-like portions 46 are arranged at intervals in the circumferential direction. In the illustrated example, three rod-like portions 46 are arranged at equal intervals in the circumferential direction. The plurality of rod-like portions 46 are arranged so that their protruding ends are connected on the cap axis O.

  As shown in FIG. 4, the rod-like portion 46 is formed with a sharpened portion 46 a that is convex toward the inside of the container body 20. The sharpened portion 46a is gradually reduced in width from the upper side to the lower side, and has a triangular shape that forms an acute angle downward in a cross-sectional view orthogonal to both the cap axis O direction and the extending direction of the rod-like portion 46. ing. As shown in FIG. 3, the sharpened portion 46 a is formed over the entire length of the rod-shaped portion 46 in the extending direction.

When the discharge container 10 as shown in FIG. 1 is used, the overcap 33 is first removed, and the container body 20 is reduced in volume by, for example, squeezing deformation (elastic deformation) of the container body 20. Then, the internal pressure of the container body 20 rises to a positive pressure, and the elastic film portion 40 elastically deforms toward the outside of the container body 20 so as to expand the slit 43 by this positive pressure, whereby the communication hole 39 is formed. The communication hole 39 is opened to communicate with the outside.
At this time, the contents in the container main body 20 pass through the communication hole 39 and the separation space 45 and reach the elastic film part 40. The contents are crushed, for example, by coming into contact with the rod-shaped portion 46 from the inside of the container body 20, and then discharged to the outside through the slit 43.
After that, when the internal pressure of the raised container body 20 decreases, for example, by stopping or releasing the squeeze deformation of the container body 20, the elastic film portion 40 is directed toward the inside of the container body 20 by the elastic restoring force. As a result, the slit 43 is closed.

  As described above, according to the discharge cap 30 according to the present embodiment, since the crushing portion 44 is disposed in the communication hole 39, the content passing through the communication hole 39 is crushed and the size of the content is increased. It is possible to reduce the thickness, and it is possible to suppress clogging of the contents discharged from the widened slit 43 into the slit 43 and facilitate discharge of the contents smoothly.

  Further, since the crushing portion 44 is separated from the elastic membrane portion 40, the contents are not allowed to reach the elastic membrane portion 40 immediately after starting to be crushed by the crushing portion 44, but started to be crushed by the crushing portion 44. Thereafter, the elastic film part 40 can be reached after passing through the space 45 between the crushing part 44 and the elastic film part 40. Therefore, even if the contents are large, it is possible to continue crushing by the crushing part 44 while passing through the separation space 45 from when the contents start to be crushed by the crushing part 44 until reaching the elastic film part 40. Therefore, it is possible to reliably prevent the clogging portion 44 from crushing the large contents effectively and clogging the contents into the slit 43.

  Furthermore, since the rod-like portion 46 is formed with a sharpened portion 46a that is convex toward the inside of the container body 20, the content can be effectively crushed by the crushing portion 44, and the content is further smoothened. Can be easily discharged.
