Description

  The present invention relates to a discharge cap.

Conventionally, for example, a discharge cap as shown in Patent Document 1 below is known. The discharge cap communicates with the discharge hole through which the contents are discharged, the discharge hole and the inside of the container body, and communicates with the discharge hole from the lower side, which is the container body side in the vertical direction along the cap axis. And a hole. The discharge cap includes a valve body that opens and closes the communication hole. And the valve body opens and closes the communication hole by elastically displacing in the vertical direction so as to approach and separate from the discharge hole in the communication space that connects the discharge hole and the communication hole.
In this discharge cap, when the valve body is elastically displaced to the upper side, which is the side opposite to the container body in the vertical direction, and the communication hole is opened, the contents move along the outer peripheral edge of the valve body according to the opening amount of the valve body. After passing through the valve body toward the upper side, it goes straight along the inner peripheral surface of the communication space and is discharged to the outside from the discharge hole.

JP 2011-246182 A

  By the way, in this type of discharge cap, the opening amount of the valve body varies based on the elastic displacement amount along the vertical direction of the valve body. Here, since the amount of elastic displacement of the valve body is easily different for each circumferential position in the valve body, the flow rate of the contents passing through the valve body may vary for each circumferential position in the valve body. In this case, in the conventional discharge cap, the flow rate of the content discharged to the outside from the discharge hole varies from position to position and the flow of the content is disturbed, and the content is discharged from the discharge hole to a desired position with high accuracy. It becomes difficult to do.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to discharge contents from a discharge hole with high accuracy.

In order to solve the above problems, the present invention proposes the following means.
The discharge cap according to the present invention communicates the discharge hole through which the contents are discharged, the discharge hole and the inside of the container main body, and the lower side which is the container main body side in the vertical direction along the cap axis. A discharge cap provided with a valve body that opens and closes the communication hole, and the valve body is in a communication space that connects the discharge hole and the communication hole. The communication hole is opened and closed by elastic displacement in the vertical direction so as to approach and separate from the discharge hole, and the communication space is formed on the outer peripheral edge of the valve body on the side opposite to the container body in the vertical direction. An annular guide portion facing from an upper side is provided, and the guide portion guides contents from the communication hole toward an inner side in a radial direction of the guide portion.

In this case, when the valve body is elastically displaced upward to open the communication hole, the contents reach the guide portion after passing through the valve body toward the upper side along the outer peripheral edge of the valve body, and the guide portion It is led and gathered inside the radial direction. Thereby, the dispersion | variation for every position about the flow volume of the content which passes the inside of a guide part is suppressed smaller than the dispersion | variation for every position about the flow volume of the content which passed the valve body. Thereafter, the contents flow upward in the communication space through the inside of the guide portion, reach the discharge holes, and are discharged from the discharge holes to the outside.
In this discharge cap, after the dispersion | variation for every position about the flow volume of a content is suppressed small by a guide part, this content can be discharged from a discharge hole. Thereby, it is possible to suppress the occurrence of disturbance in the flow of the contents discharged from the discharge holes, and to discharge the contents from the discharge holes with high accuracy.

  The inside of the guide portion may face the valve body from above over the entire area.

  In this case, since the inside of the guide portion faces the valve body from the upper side over the entire area, the contents that have passed through the valve body toward the upper side along the outer peripheral edge of the valve body directly reach the inside of the guide portion. Can be suppressed. That is, it is possible to make it easy for the contents to pass through the guide part before reaching the inside of the guide part. Therefore, the contents can be effectively aggregated by guiding the contents to the inside in the radial direction of the guide part by the guide part. Thereby, the dispersion | variation for every position about the flow volume of the content which passes the inside of a guide part can be reliably suppressed small.

  The communication space includes a large diameter portion in which the communication hole is provided in a lower end portion, and a small diameter portion that extends upward from the large diameter portion and in which the discharge hole is provided in the upper end portion, and the guide The portion may be formed by a step portion connecting the inner peripheral surface of the large diameter portion and the inner peripheral surface of the small diameter portion.

  In this case, since the guide portion is formed by a step portion that connects the inner peripheral surface of the large diameter portion and the inner peripheral surface of the small diameter portion, the guide portion is formed by a part of the wall surface that defines the communication space. can do. Thereby, simplification of a structure can be achieved.

  The guide portion may include an inclined portion that gradually extends downward toward the inner side in the radial direction of the guide portion.

  In this case, since the guide portion includes the inclined portion, when the guide portion guides the contents to the inside in the radial direction of the guide portion, the contents can be easily retained on the guide portion. Therefore, the contents can be effectively aggregated. Thereby, the dispersion | variation for every position about the flow volume of the content which passes the inside of a guide part can be reliably suppressed small.

  A protruding portion that protrudes upward may be provided in a portion of the valve body located on the axis of the guide portion.

  In this case, since the projecting portion is provided at a portion of the valve body that is located on the axis of the guide portion, the contents guided to the inside in the radial direction of the guide portion by the guide portion are collected in the communication space. The volume of the space can be reduced by the protrusion. Therefore, the contents can be effectively aggregated. Thereby, the dispersion | variation for every position about the flow volume of the content which passes the inside of a guide part can be reliably suppressed small.

  According to the present invention, the contents can be discharged from the discharge hole with high accuracy.

  Next, the operation of the discharge cap 10 will be described.

  When the container body W is elastically deformed after the discharge hole 11 is opened by the lid body 16, the internal pressure in the container body W rises and acts on the concave portion of the valve body 14, and the valve body 14 is moved upward. The communication hole 13 is opened due to elastic displacement. Then, after the contents pass through the valve body 14 toward the upper side along the outer peripheral edge of the valve body 14, the contents reach the guide portion 40 and are guided and aggregated in the radial direction. Thereby, the dispersion | variation for every position about the flow volume of the content which passes the inside of the guide part 40 is suppressed smaller than the dispersion | variation for every position about the flow volume of the content which passed the valve body 14. FIG. Thereafter, the contents flow through the inside of the guide portion 40 further upward in the communication space 17 to reach the discharge holes 11 and are discharged from the discharge holes 11 to the outside.

  As described above, according to the discharge cap 10 according to the present embodiment, the variation in the flow rate of the contents for each position is suppressed by the guide unit 40, and then the contents are discharged from the discharge holes 11. Can do. Thereby, it is possible to suppress the disturbance of the flow of the contents discharged from the discharge holes 11 and to discharge the contents from the discharge holes 11 with high accuracy.

  Moreover, since the inside of the guide part 40 faces the valve body 14 from the upper side over the entire area, the contents that have passed through the valve body 14 toward the upper side along the outer peripheral edge of the valve body 14 are directly Reaching the inside can be suppressed. That is, it is possible to easily pass the contents through the guide unit 40 before the contents reach the inside of the guide unit 40. Therefore, the contents can be effectively collected by guiding the contents to the inside in the radial direction by the guide unit 40. Thereby, the dispersion | variation for every position about the flow volume of the content which passes the inside of the guide part 40 can be suppressed reliably small.

  Moreover, since the guide part 40 is provided with the inclination part 43, when the guide part 40 guides the content to the inner side of radial direction, it can make it easy to make this content fasten on the guide part 40. Therefore, the contents can be effectively aggregated. Thereby, the dispersion | variation for every position about the flow volume of the content which passes the inside of the guide part 40 can be suppressed reliably small.

  In addition, since the protruding portion 38 is provided in a portion of the valve body 14 that is located on the reference axis O2, in the communication space 17, a space in which contents guided radially inward by the guide portion 40 are collected. Can be reduced by the protrusion 38. Therefore, the contents can be effectively aggregated. Thereby, the dispersion | variation for every position about the flow volume of the content which passes the inside of the guide part 40 can be suppressed reliably small.

  Moreover, since the guide part 40 is formed by the step part 17c which connects the internal peripheral surface of the large diameter part 17a, and the internal peripheral surface of the small diameter part 17b, the guide part 40 is the wall surface which defines the communication space 17. It can be formed in part. Thereby, simplification of a structure can be achieved.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, a discharge cap as shown in FIG. 3 may be employed. In this discharge cap, instead of providing the lip portion 22c at the upper end of the discharge cylinder 22, a portion of the upper end surface of the discharge cylinder 22 positioned on the front side is along an orthogonal plane orthogonal to the reference axis O2. It extends. Further, the valve body 34 is formed in a flat plate shape instead of providing the protrusion 38 and the like on the valve body 34. Further, instead of providing the guide portion 40 with the ridge portion 41, the flat portion 42, and the inclined portion 43, the guide portion 40 is constituted only by the flat portion 42.

  Moreover, in the said embodiment, although the guide part 40 is formed of the step part 17c, this invention is not limited to this. For example, an annular plate-like member may be provided in the communication space 17 and the guide portion 40 may be formed by this member.

Further, the leg portion 31a may not be provided.
Moreover, although the said embodiment showed the structure by which the elastic hinge part 32 and the elastic connection piece 35 were arrange | positioned two each, you may arrange | position one by one.

Moreover, in the said embodiment, although the valve body 14 was provided with the valve main body 34 and the elastic connection piece 35, and the 2nd weakening part 36 and the 3rd weakening part 37 were formed, this invention showed this Not limited. For example, the valve body 14 includes only the valve main body 34, the second weakened portion 36 and the third weakened portion 37 are not formed, and a part of the outer peripheral edge of the valve main body 34 is one elastic hinge portion 32. It is also possible to employ a configuration in which the remaining portion is connected to the inner peripheral edge of the communication hole 13 via the first weakened portion 33 that is connected to the inner peripheral edge of the communication hole 13 and that can be broken.
Further, the cap body 12 and the inner plug member 15 may be integrally formed.

Further, the timing at which the first weakened portion 33 and the like are broken by applying a force from the inside to the outside of the container main body W to the valve body 14 is not limited to the above embodiment, and may be changed as appropriate.
For example, it may be before the mold is opened in the mold for molding the inner stopper member 15, or after the inner stopper member 15 is attached to the cap body 12 and before the discharge cap 10 is attached to the container body W. May be. Furthermore, it may be after the container body W is filled with the contents and the discharge cap 10 is attached. In this case, you may fracture | rupture the 1st weakening part 33 grade | etc., By raising the internal pressure by elastically deforming the container main body W etc.

  Further, the valve body 14 is not limited to the configuration shown in the above embodiment, and the communication hole 13 is opened and closed by elastically moving in the vertical direction so as to approach and separate from the discharge hole 11 in the communication space 17. It can change suitably to other composition. For example, a configuration without the first weakening portion 33 may be adopted as the valve body 14. As the valve body 14, a so-called three-point valve or one-point valve may be employed.

  In addition, it is possible to appropriately replace the constituent elements in the embodiment with known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
