Description

  The present invention relates to a cap provided with a slit valve, and in particular, it is possible to realize the biasing of the lid body covering the slit valve toward the open side without increasing the number of parts.

  As a container for storing cosmetics, facial cleansers, etc., the contents can be easily discharged in an expected amount and can exhibit good liquid drainage performance. As is known, a device equipped with a cap having a slit valve is known. Here, the slit valve is made of a soft material such as rubber or elastomer, and is elastically deformed by pressing the inside of the container and pressing the inside of the container, and a cross-shaped cut (slit) provided on the top is formed. By being opened instantly, an appropriate amount of contents can be discharged. In this case, as shown in FIG. 2 of the same document, a cylinder surrounding the slit valve is provided around the slit valve to protect the slit valve from being inadvertently touched. It is common.

  By the way, the hinged lid body can be easily opened with one hand, and can stably exhibit high durability even when used repeatedly. Like the cap, it is particularly preferable to hinge the lid to the cap body and apply an urging force to the lid using an elastic member made of a soft material. As described above, since the slit valve is surrounded by the cylindrical body, it is usual to newly provide an elastic member different from the slit valve. For this reason, the number of parts as a whole cap increases, and the man-hour for attaching the cap also increases, and there is still room for improvement.

It is a cap with a slit valve characterized by holding fixed.

  It is preferable that the connection part is an insertion part that connects the extension part and the slit valve through a through hole provided in a side wall of the cylindrical body.

  It is preferable that the connecting portion is a bypass portion that crosses the tip of the cylindrical body and connects the extending portion and the slit valve.

  The elastic member for urging the lid to the open side includes an extending part that extends toward the cylinder surrounding the slit valve, and a connecting part that connects the extending part and the slit valve beyond the cylinder. The elastic member, the extending portion, the connecting portion, and the slit valve are integrally connected with the same soft material, and the elastic member, the extending portion, the connecting portion, and the slit valve are formed by insert molding or two-color molding. Since the cap body and the lid are fixed and held, the contents can be discharged in an appropriate amount, and the function that allows the lid to be easily opened with one hand is maintained, and the increase in the number of parts and the number of mounting steps can be suppressed. it can.

  The connecting portion is an insertion portion that connects the extending portion and the slit valve through a through-hole provided in the side wall of the cylindrical body, or a bypass portion that crosses the tip of the cylindrical body and connects the extending portion and the slit valve. In this case, the configuration of the connecting portion is simplified, and the connecting portion can be configured with the minimum necessary soft material.

  As shown in FIG. 2, the slit valve 30 is provided inside the cylindrical body 16 of the cap body 10. Here, the slit valve 30 is formed of a soft material such as rubber or elastomer, and integrally connects a cylindrical inclined portion 32 extending downward to the edge of the concavely curved top wall 31, and this inclination. The lower end of the portion 32 is integrally connected to the annular base portion 33. Further, the top wall 31 is formed with a slit 31a provided in a cross shape in the illustrated example. In addition, the slit 31a having a shape corresponding to the type of contents such as a letter shape or a star shape is appropriately adopted. Further, as shown in FIGS. 2 and 4, an annular body 31 b surrounding the slit 31 a is provided on the back surface of the top wall 31.

  As shown in FIG. 6, the elastic member 40 is provided with a gap s between the two hinges h. As shown in FIG. 2, the connecting piece 41 provided on one end side of the elastic member 40 is attached to the lid 20. The connection wall 25 is connected. Further, as shown in FIGS. 2 and 6, the other end side is provided with an extending portion 42 extending along the outer cylinder 13 and the upper wall 11 of the cap body 10, and the slit valve 30 and the extending portion are extended. The installation part 42 is mutually connected by the connection part 43 beyond the cylinder 16. FIG.

  In the first embodiment, the connecting portion 43 is provided as an insertion portion 43a that integrally connects the base portion 33 and the extending portion 42 through the through hole 17a, as shown in FIG. Thereby, the elastic member 40, the extending part 42, the insertion part 43a, and the slit valve 30 are formed with the same soft material. In providing the elastic member 40 and the like on the cap body 10 and the lid 20, either the elastic member 40 or the cap body 10 or the like is molded in advance, and this is loaded into the other mold. It is preferable to integrally connect by insert molding to be molded, or two-color molding in which one of the two is molded and combined with the other mold while being left as a part of the mold. The number of assembling steps of the members can be sufficiently reduced, and both can be securely fixed. The elastic member 40 and the like in the first embodiment are preferably provided by insert molding.

  And in 1st Embodiment, as shown in FIG. 2, the holding | maintenance part arrange | positioned between the inner cylinder 12 and the outer cylinder 13 through the clearance gap 13c of the cap main body 10 on the other end side of the elastic member 40. 44 is preferably provided, so that the elastic member 40 can be retained against the cap body 10.

  Furthermore, in the first embodiment, as shown in FIGS. 5 and 6, it is preferable to provide a ring 45 that is integrally connected to the extending portion 42 and fits into the annular groove 11 c provided in the upper wall 11. Thus, it is possible to reliably prevent the slit valve 30 from coming out downward. On the other hand, the upward pull-out is reliably prevented by the insertion portion 43a provided below the through hole 17a as shown in FIG. 2 and the base portion 33 provided below the upper wall 11 as shown in FIG. be able to.

  As shown in FIG. 2, the cap with the slit valve configured as described above is configured such that when the lid 20 is closed, the outer claw 16 a of the cylinder 16 and the inner claw 24 a of the lid cylinder 24 are engaged. The lid 20 can be maintained in the closed posture. At this time, since the protruding portion 23 of the lid 20 is in contact with the top wall 31 of the slit valve 30, the top wall 31 is not lifted up and the slit is not opened even when the body portion 1b of the container 1 is pressed. Inadvertent leakage of contents can be effectively prevented.

  And when pouring out the contents, the elastic member 40 is restored to the original linear shape by pushing the finger catching portion 26 and pushing it up. 7, the lid 20 can be changed to the open posture. Since the elastic member 40 is formed of a soft material that is the same material as the slit valve 30, the initial urging force is stably maintained even when used repeatedly.
