US 7530467 B2Abstract
1. A cap mounting arrangement in which a cap with a sealing member is detachably attached to a container to hermetically close an opening of the container, wherein
the cap comprises an insert part having a cylindrical shape closed at one end and a flange provided at said closed one end of the insert part,
the insert part has a radially expandable and contractible engaging part that extends radially outwardly from the distal end of the outer periphery of the insert part and a sealing groove that is formed in the outer periphery of the insert part between the engaging part and the flange to receive the sealing member,
the opening of the container is provided with a cylindrical part into which the insert part of the cap is tightly inserted with the engaging part contracted radially inwardly, and
the inner periphery of the cylindrical part has an engaging groove including: a deepest part that engages with the engaging part with the engaging part expanded radially outwardly when the cap is attached to the cylindrical part; and a guide extending to gradually decrease its radial depth from the deepest part in a circumferential direction so that when the cap is turned for removal, the engaging part engaged in the deepest part can be contracted radially inwardly to allow the cap to be removed.
2. The cap mounting arrangement of claim 1, wherein the external end of the inner periphery of the cylindrical part has an inserting recess that extends to gradually decrease its radial depth toward the deepest part of the engaging groove, thereby guiding the engaging part toward the deepest part during insertion of the cap into the cylindrical part.
3. The cap mounting arrangement of claim 1, wherein
one of the back side of the flange of the cap and the external end surface of the cylindrical part has a push-out projection for pushing the cap toward outside the cylindrical part, and
the other of the back side of the flange of the cap and the external end surface of the cylindrical part has a receiving recess including: a bottom capable of accommodating the push-out projection; and a projection climbing surface raised from the bottom so that after the engaging part of the cap engaged in the deepest part of the engaging groove of the cylindrical part is disengaged from the engaging groove through the turning of the cap, the push-out projection pushes the cap toward outside the cylindrical part.
4. The cap mounting arrangement of claim 2, wherein
the other of the back side of the flange of the cap and the external end surface of the cylindrical part has a receiving recess including: a bottom capable of accommodating the push-out projection; and a projection climbing surface raised from the bottom so that after the engaging part of the cap engaged in the deepest part of the engaging groove of the cylindrical part is disengaged from the engaging groove through the turning of the cap, the push-out projection pushes the cap toward outside the cylindrical part. Description
This application claims priority under 35 USC 119 to Japanese Patent Application No. 2004-271888, filed on Nov. 17, 2004, the entire contents of which are incorporated herein by reference.
The cap 1 comprises, as shown in enlarged detail in FIGS. 1 to 4, a bottomed cylindrical cap body 19 consisting of a flat part 15 and a cylindrical part 17 formed integrally with the outer peripheral edge of the flat part 15. An annular sealing groove 17 a of substantially U-shaped cross section is recessed substantially in the axial middle of the outer periphery of the cylindrical part 17 of the cap body 19. A sealing member, for example, a rubber-made O-ring 21, is seated into the sealing groove 17 a. The cylindrical part 17 of the cap body 19 is fitted through the O-ring 21 into the opening 11 of the cylindrical part 9 of the cylinder head cover 3, and in this fitting relationship the O-ring 21 is brought into close contact with the inner periphery of the cylindrical part 9 to hermetically close the opening 11. Note that the O-ring 21 is not given in FIG. 1 for the clarity of the sealing groove 17 a. At two opposite points existing on the peripheral edge of the flat part 15 of the cap body 19 on the opposite side of the cap body 19 to the direction of fitting and located equally away from the center of the cap body 19, i.e., at two opposite points that exists on the peripheral edge of the flat part 15, passes through the center of the cap body 19 and are disposed 180� apart, a pair of L-shaped, flexible engaging arms 27 are formed integrally with the cap body 19 to extend therefrom. More specifically, each engaging arm 27 is formed of a horizontal arm 26 horizontally outwardly extending from one of the two opposite positions, and a pendent arm 28 extending in the direction of fitting (downward) from an extending end 26 a of the horizontal arm 26 so as to be parallel to and spaced a distance C1 away from the outer periphery of the cylindrical part 17 of the cap body 19. Further, a claw-like engaging projection 25 is formed on the inner side of the distal end (lower end) of the pendent arm 28 to correspond to the engaging recess 13 of the cylinder head cover 3 (cylindrical part 9). The distance C1 is set at a value at which the pendent arms 28 of the pair of engaging arms 27 are located outside the cylindrical part 9 when the cap 1 is attached to the cylindrical part 9 of the cylinder head cover 3. The distal ends of the pendent arms 28 of the pair of engaging arms 27 are connected to each other through a pair of flexible connecting bridges 29 to surround the outer periphery of the cylindrical part 17 of the cap body 19 with a distance therebetween. The connecting bridges 29 have an elliptical shape as a whole in a plan view. Push parts 23 are formed in the circumferential middles of the pair of connecting bridges 29, respectively. The pair of connecting bridges 29 are both elastically deformed by pinching the push parts 23 with fingers and pushing them to come close to each other, thereby allowing both the engaging projections 25 to get away from the cylindrical part 17 of the cap body 19. As a result, both the engaging projections 25 are released from engagement with the engaging recess 13. On the other hand, the distance C2 between the push parts 23 and the outer periphery of the cylindrical part 17 of the cap body 19 is set larger than the distance C1 between the dependent arms 28 of the engaging arms 27 and the outer periphery of the cylindrical part 17 of the cap body 19. In other words, the push parts 23 are located at both ends of the longer diameter of the ellipse, while the engaging arms 27 are located at both ends of the shorter diameter of the ellipse. The elliptical shape increases the degree of deformation of the connecting bridges 29 to facilitate the disengagement of the engaging projections 25 from the engaging recess 13.
