no. 2 Embodiment approach

[0079] use Figure 12, the second embodiment of the present invention will be described. This embodiment is similar to the first embodiment, and the main difference is the structural difference of the discharge port 23f of the nozzle 23 and the discharge cylindrical portion 23c. Hereinafter, the difference will be mainly described.

[0080] In the present embodiment, in the nozzle 23, the position of the discharge port 23f is eccentric. Therefore, if Figure 12 As shown in B, in a plan view, the discharge port 23f is not concentric with the flow hole 21a. Moreover, the discharge cylindrical part 23c is provided with the regulation wall 23c1 which inclines so that the discharge cylindrical part 23c may be narrowed as it approaches the discharge port 23f. The regulation wall 23c1 overlaps with the flow hole 21a in plan view, and reduces the force of discharge of the built-in similarly to the regulation wall 23e of the first embodiment.

no. 3 Embodiment approach

[0082] use Figure 13 , the third embodiment of the present invention will be described. The present embodiment is similar to the first embodiment, and the main difference is the configuration of the discharge port 23f of the nozzle 23 and the discharge cylindrical portion 23c. Hereinafter, the difference will be mainly described.

[0083] In the present embodiment, in the nozzle 23, the position of the discharge port 23f is not eccentric. Therefore, if Figure 13 As shown in B, in a plan view, the discharge port 23f and the flow hole 21a are concentric. The discharge cylindrical portion 23c includes a reduced diameter portion 23c2 whose diameter is reduced as it approaches the discharge port 23f, and a constant diameter portion 23c3 whose diameter does not change as it approaches the discharge port 23f.

[0084] In the nozzle 23, a plurality of (three in the present embodiment) arm portions 23j protruding from the inner surface of the nozzle 23 are provided. The pluralit...

Abstract

Provided is a cover having a check valve that can be opened and closed smoothly. According to the present invention, there is provided a cap to be attached to the mouth of a container for accommodating contents, wherein the cap includes a valve body and a base, the valve body includes a flow hole, and the valve body When the internal pressure from the built-in is not applied to the annular portion around the flow hole, the edge of the flow hole abuts on the base to close the flow hole, and the internal pressure When applied to the annular portion around the flow hole, the valve body is elastically deformed, so that the edge of the flow hole leaves the base to open the flow hole.

Description

【Technical field】 [0001] The present invention relates to a cap provided with a check valve, and a stacked peel container having a layer provided with the cap. 【Background technique】 [0002] Patent Document 1 discloses a cap having a split valve provided with a split in the discharge valve. [0003] 【Existing technical documents】 [0004] 【Patent Literature】 [0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-95455 [Content of the invention] [0006] 【The problem to be solved by the invention】 [0007] The split valve of Patent Document 1 has a problem that the split valve does not open when the container is slightly compressed, and it is difficult to discharge the contents. [0008] The present invention was made in view of such a situation, and an object thereof is to provide a cover having a check valve that can be opened and closed smoothly. [0009] 【Means for solving problems】 [0010] According to the present invention, there is provid...
