Patent number: 10781017Abstract: Provided is a cap (11) used for a discharge container (1) and provided on a mouth portion (32) of a container main body (10) which is deformed by a pressing force and stores contents (100). The cap (11) includes: a base portion (51) having an annular bottom wall (64) having a discharge port (64a), an annular groove (64c) provided in an outer peripheral edge of the bottom wall (64), a flow port (64d) provided in the groove (64c), and a flow groove (64e) connected to the flow port (64d); a check valve (53) having a cylindrical support portion (81) having one end disposed in the groove (64c), a plurality of elastic pieces (82) connected to the support portion (81), and a valve body (83) connected to the plurality of elastic pieces (82) and opening and closing the discharge port (64a); and a discharge nozzle (52) covering the bottom wall (64).Type: GrantFiled: April 24, 2017Date of Patent: September 22, 2020Assignees: TOKYO LIGHT INDUSTRY CO., LTD., KYORAKU CO., LTD.Inventors: Takaaki Sakimura, Masashi Sasaki, Shouji Uehira, Satoshi Ichikawa

Patent number: 10689167Abstract: In the container, when the cap is capped on the container opening portion, an inner wall surface of a cylindrical sub-fitting wall portion of the cap and an outer wall surface of a large diameter opening portion of the container opening portion closely contact each other, and an outer wall surface of a cylindrical main fitting wall portion of the cap and an inner wall surface of a small diameter opening portion of the container opening portion closely contact each other. In this way, pressing force that is applied to the outer wall surface of the cylindrical main fitting wall portion of the cap from the inner wall surface of the small diameter opening portion of the container opening portion is increased.Type: GrantFiled: March 25, 2016Date of Patent: June 23, 2020Assignees: TOKYO LIGHT INDUSTRY CO., LTD., KYORAKU CO., LTD.Inventors: Takaaki Sakimura, Masashi Sasaki, Masashi Mizuochi, Hajime Sasaki, Satoshi Ichikawa

Patent number: 10259624Abstract: An annular protruding portion (17) is provided around an inner plug (13) at a radial interval on an annular horizontal wall portion (20) of a cap body 4. Between an annular flange portion (43a) of the inner plug (13) and the annular protruding portion (17), an annular accumulating groove portion (33) is provided. Particularly in the case of a liquid content, the liquid content may be scattered from within a cylindrical guide portion (42) when a lid member (5) is placed after use. The liquid content, however, is blocked by the annular protruding portion (17) and prevented from flowing further outward, while interfering with a top surface portion (51) and a cylindrical scattering suppression portion (55) of the lid member (5). Thus, downward flow of the liquid content along the outer wall surface of the annular horizontal wall portion (20) of a main cap member (11) can be suppressed.Type: GrantFiled: March 25, 2016Date of Patent: April 16, 2019Assignees: TOKYO LIGHT INDUSTRY CO., LTD., KYORAKU CO., LTD.Inventors: Takaaki Sakimura, Masashi Sasaki, Masashi Mizuochi, Hajime Sasaki, Satoshi Ichikawa

Patent number: 9637282Abstract: A cap body of a cap includes: a cylindrical inner wall section to be fitted into an inner wall surface of a container mouth section; an annular wall section that extends obliquely in an upper direction toward a radial-direction center integrally from an inner wall surface of the cylindrical inner wall section, has a lower wall surface of a truncated conical shape, and has a discharge hole in a radial-direction center portion; a check valve disposed above the annular wall section to open or close the discharge hole in such a manner that a valve section is detached from or seated on an annular valve seat around the discharge hole; and a guiding tubular body disposed above the check valve and having a discharge passage of contents from the discharge hole. Therefore, at the time of using the contents, the contents can be smoothly discharged to the outside.Type: GrantFiled: October 10, 2014Date of Patent: May 2, 2017Assignee: TOKYO LIGHT INDUSTRY CO., LTD.Inventors: Takaaki Sakimura, Masashi Sasaki, Masashi Mizuochi, Hajime Sasaki, Satoshi Ichikawa
