Description

  The present invention relates to an extraction cap that is attached to the mouth of a container that contains contents.

  Conventionally, for example, containers that contain contents such as cosmetics, cleaning agents, or drugs can be kept closed when not in use, but can be easily opened and used in the intended state when not in use. It is common to have an extraction cap that can extract objects.

  Various types of such extraction caps have been proposed depending on the purpose. For example, Patent Document 1 discloses a cap having a child proof function that is not easily opened even when a child touches it. Here, the cap of Patent Document 1 is obtained by connecting a cap body and a lid with a hinge, and further, a locking projection is provided on the cap body, and the lid is locked to the locking projection. A locking engagement portion is provided.

JP 2012-131533 A

  By the way, the cap described in Patent Document 1 has a locking engagement portion that protrudes from the outer peripheral surface of the cap body. Therefore, when a child touches the cap carelessly, a finger is caught on the locking engagement portion, which lifts up. Therefore, there is a possibility that the lock body is released and the lid body is opened as it is. As described above, in the conventional cap as described in Patent Document 1, when the locking engagement portion is lifted, the lid is also opened by the upward force to release the lock. The function might not work effectively.

  The present invention has been made to solve the above-described problems, and provides a new extraction cap that can effectively open the lid for those who know the opening method more effectively, and that the child proof function is more effective. The purpose is to do.

The present invention is a cap body that is attached to the mouth of a container that contains the contents and has a content extraction port;
A lid that is detachably attached to the cap body, and covers the extraction port when attached,
An extraction cap comprising a ring member and a slide member movably provided on the cap body between an upper position covering the outer peripheral wall of the lid and a lower position exposing the outer peripheral wall,
The slide member includes a protrusion that protrudes inward, and a pressing portion that bends the slide member by pressing the slide member inward and moves the protrusion outward.
The protrusion engages with an engaging portion provided on the cap body to hold the slide member in the upper position, and when the pressing portion is pressed, the protrusion is detached from the engaging portion and below the slide member. It is an extraction cap that allows movement to

  The cap body is preferably of a stopper type that is attached to the container by stoppering.

  It is preferable that the cap main body has a side wall that is located on a side of the protrusion and guides the protrusion when the slide member is moved up and down.

  It is preferable that at least a pair of the pressing parts are provided on the slide member in an opposing arrangement, and at least a pair of the protrusions are provided in an opposing arrangement in a direction orthogonal to the direction in which the pressing parts oppose.

  The lid body is connected to the cap body so as to swingably hold the lid body on the cap body, and protrudes outward at an upper end of the outer peripheral wall, and the slide member at the upper position. It is preferable to have a collar part aligned with the peripheral wall.

  The extraction cap of the present invention includes a slide member that is movably provided on the cap body between an upper position that covers the outer peripheral wall of the lid and a lower position at which the outer peripheral wall is exposed. , A protrusion protruding inward, and a pressing portion that bends the slide member by pressing the slide member inward to move the protrusion outward. The protrusion engages with the engaging portion provided on the cap body to hold the slide member in the upper position, and when the pressing portion is pressed, it disengages from the engaging portion and allows the slide member to move downward. Is. That is, by pressing the pressing portion, even if the engagement between the protrusion and the engaging portion is released and the slide member becomes movable, the slide member must be moved downward before opening the lid. The lid does not open by a series of operations. Therefore, the possibility that the lid will open even if the child touches carelessly is small, and for those who know the opening method, the lid can be opened by simply moving the slide member downward. Therefore, the lid can be easily opened.

  By the way, there is a type in which the cap body is attached to the container by a screw, but in this case, if the entire extraction cap is grasped and rotated, there is a possibility that the screw is disengaged and the extraction cap is detached from the container. For this reason, the cap body is preferably a stopper type that is attached to the container by stoppering, and in this case, the child proof function can be more reliably exhibited.

  When the cap body is provided with a side wall that is positioned on the side of the protrusion and guides the protrusion when the slide member is moved up and down, the slide member can be stably moved up and down. Further, in this case, since the projection and the side wall also function as a detent for the slide member, the slide member does not rotate during the movement.

  And it is preferable that at least one pair of pressing parts is provided on the slide member in an opposing arrangement, and at least one pair of protrusions is provided in an opposing arrangement in a direction orthogonal to the direction in which the pressing parts oppose. That is, since the protrusion is disposed at a portion where the movement amount increases when the pressing portion is pressed, the engagement between the protrusion and the engaging portion can be reliably released by pressing the pressing portion. Further, since the projections are plural, the slide member can be reliably held at the upper position.

  The lid may be detachably attached to the cap body by screwing, or may be connected to the cap body via a hinge. In this case, it is preferable to provide a flange that protrudes outward and aligns with the peripheral wall of the slide member at the upper position at the upper end of the outer peripheral wall of the lid. As a result, at the upper position, the peripheral wall of the slide member and the collar portion of the lid body are aligned, so that the lid body cannot be opened, while at the lower position, the outer peripheral wall of the lid body is exposed. Since a finger can be hung on the part, the collar part becomes a finger hook and the lid is easily opened.

The state which moved the slide member to the lower position is shown, (a) is a sectional view along CC of (b), (b) is a half sectional view of the side view in the state attached to the container. . It is a side view which shows the state which opened the cover body.

  Hereinafter, an embodiment of the extraction cap according to the present invention will be described mainly with reference to FIG. In addition, as shown in FIG. 1B, “upper” and “lower” in this specification and the like indicate a state in which the cap body indicated by reference numeral 10 is positioned below and the lid body indicated by reference numeral 20 is positioned above. The direction at.

  The extraction cap of the present embodiment includes a cap body indicated by reference numeral 10 in FIG. 1, a lid indicated by reference numeral 20, and a slide member indicated by reference numeral 30. Moreover, the code | symbol 40 has shown the container which attaches an extraction cap.

  First, the container 40 will be described. The container 40 includes a trunk 41 that rises from the bottom (not shown), a shoulder 42 that is connected to the upper end of the trunk 41 and that extends while tilting slightly upward toward the central axis O of the container 40, and a shoulder 42. And a cylindrical mouth portion 43 that rises upward from the inner edge. Further, the outer peripheral surface of the mouth portion 43 is provided with a protruding portion 44 that protrudes away from the central axis O. In addition, an inner space M that can contain contents is provided inside the container 40.

  Next, the cap body 10 will be described. The cap body 10 includes a disk-shaped top wall 11 that is located above the mouth portion 43 and covers it. In the center of the top wall 11, an extraction port 12 that penetrates the top wall 11 and communicates with the internal space M is provided. Further, an annular extraction cylinder 13 that rises upward is provided at the edge of the extraction port 12. On the lower surface of the top wall 11, a cylindrical cap body seal wall 14 that is in liquid-tight contact with the inner peripheral surface of the mouth portion 43, and an engagement tube 15 that surrounds the outside of the mouth portion 43 and engages with the protruding portion 44. An annular wall 16 having a diameter larger than that of the engagement cylinder 15 is provided. The annular wall 16 is recessed so that a part thereof is located inside the outer edge of the top wall 11, and a gap is formed between the outer peripheral surface of the annular wall 16 at this portion and the outer edge of the top wall 11. A claw-like engaging portion 17 that forms S is provided. Here, although the upper surface of the engaging portion 17 extends in the horizontal direction, the lower surface thereof is inclined so as to approach the central axis O as it goes downward. Further, side walls 18 extending in the vertical direction are provided on both sides in the circumferential direction across the engaging portion 17.

  The lid 20 includes a disk-shaped top wall 21 that is located above the extraction cylinder 13 and covers it. On the lower surface of the top wall 21, there are provided an annular lid seal wall 22 that comes into liquid-tight contact with the outer peripheral surface of the extraction tube 13 and an annular outer peripheral wall 23 provided at a position aligned with the outer edge of the top wall 11. . Here, the outer edge of the top wall 21 protrudes outward from the outer peripheral wall 23, thereby forming a flange 24. The lid 20 includes a hinge 25 that connects the annular wall 16 and the outer peripheral wall 23, and elastic portions 26 provided on both sides of the hinge 25 (see FIG. 1A). Accordingly, the lid body 20 can be swung with respect to the cap body 10 and the opened lid body 20 can be maintained in the posture.

  The slide member 30 includes a peripheral wall 31 having a ring shape. In the plan view, the peripheral wall 31 of the present embodiment has a portion that is located outside the hinge 25 and the elastic portion 26 and a portion that faces this portion across the central axis O extends linearly. The removed portion mainly extends in a curved shape. Moreover, the outer surface of the surrounding wall 31 is formed in the magnitude | size which aligns with the collar part 24, as shown in FIG.1 (b). And the protrusion 32 which protrudes toward an inner side is provided in the internal peripheral surface of the surrounding wall 31. As shown in FIG. The protrusions 32 of the present embodiment are provided in a pair so as to face each other with the central axis O interposed therebetween, and are formed with a width that fits inside the side wall 18. The peripheral wall 31 includes a pair of pressing portions 33 in a direction orthogonal to the direction in which the two protrusions 32 are arranged. The peripheral wall 31 is formed so as to be elastically deformable, and when the two pressing portions 33 are pushed inward as shown in FIG. 2, the portions provided with the two protrusions 32 can be moved outward. In addition, the press part 33 of this embodiment is provided with the some convex rib which protrudes from the outer surface of the surrounding wall 31, and when it presses with a finger | toe, it is hard to slip. In addition, although illustration is abbreviate | omitted, you may provide the character, mark, etc. which show that this site | part is a site | part pressed with a finger | toe.

  In attaching the extraction cap having such a configuration to the container 40, the slide member 30 is inserted from below the cap body 10 after the lid 20 is closed. Then, the slide member 30 is held by the cap body 10 by lifting the slide member 30 until the protrusion 32 gets over the engagement portion 17 and fits in the gap S. After that, if the engagement tube 15 is plugged at a position where it fits into the mouth portion 43, the engagement tube 15 engages with the protruding portion 44 of the mouth portion 43, and the extraction cap is held by the container 40 so as not to be detached. The

  Here, in the state shown in FIG. 1 (the state in which the lid 20 is in the upper position), the outer peripheral wall 23 of the lid 20 is covered with the peripheral wall 31 of the slide member 30, and the collar portion 24 of the lid 20. Are aligned with the peripheral wall 31 of the slide member 30, and there is almost no step between them. For this reason, even if an infant etc. touch, the malfunction by which the cover body 20 is opened carelessly can be prevented. Note that the slide member 30 is held at the upper position because the protrusion 32 is engaged with the engaging portion 17 of the cap body 10.

  In opening the lid 20 from the state of FIG. 1, the two pressing portions 33 are pressed inward as shown in FIG. Accordingly, the peripheral wall 31 is elastically deformed, and the portions where the two protrusions 32 are provided move outward. As a result, the protrusion 32 and the engaging portion 17 are disengaged, so that the slide member 30 can be moved to the lower position. Here, since the protrusion 32 is accommodated inside the side wall 18 located on the side thereof, the side wall 18 functions as a guide for the protrusion 32 when the slide member 30 is moved to the lower position. For this reason, the slide member 30 can be moved stably. Moreover, since the side wall 18 and the protrusion 32 also function as a detent for the slide member 30, the slide member 30 does not rotate in an unintended direction during the movement.

  Then, as shown in FIG. 3, when the slide member 30 is moved to the lower position, the outer peripheral wall 23 of the lid 20 is exposed. Accordingly, if the outer peripheral wall 23 is hung with a finger, the lid 20 can be opened as shown in FIG. Here, the flange 24 that is aligned with the peripheral wall 31 in the upper position shown in FIG. 1 forms a step with the exposed outer peripheral wall 23 in the lower position shown in FIG. By doing so, the lid 20 can be easily opened. After opening the lid 20, the contents accommodated in the internal space M can be extracted from the extraction tube 13 by tilting the container 40 and further pressing the body 41 as necessary. In addition, since the shoulder part 42 of the container 40 functions as a retaining member with respect to the sliding member 30 moved to the lower position, the sliding member 30 will not fall off.

  After extracting the contents, the lid 20 is closed and the slide member 30 is moved to the upper position. Here, since the lower surface of the engaging portion 17 is inclined, when the protrusion 32 is pressed against the engaging portion 17, the protrusion 32 is guided to the outside. 32 can be engaged with the engaging portion 17.

  In the extraction cap of the present embodiment, the opening direction of the lid body 20 is determined when the lid body 20 is opened even when the engagement between the engaging portion 17 and the protrusion 32 is released and the slide member 30 is movable. The slide member 30 is configured to move downward in the opposite direction. That is, since the lid 20 does not open by a series of operations, a high child proof function is exhibited. In addition, the possibility that the lid 20 will open even if the child touches carelessly is small, and for those who know the opening method, the lid 20 can be opened by simply moving the slide member 30 downward. Therefore, the lid 20 can be easily opened. Furthermore, by moving the slide member 30 downward, the outer peripheral wall 23 of the lid body 20 is greatly exposed, and it is easy to see whether the lid body 20 is openable. Problems such as forgetting to move to the position can be effectively prevented.

  The extraction cap according to the present invention is not limited to the embodiments described so far, and includes those with various modifications within the scope of the claims. For example, in the above-described embodiment, a hinge that integrally connects the cap body and the lid is provided, and the lid 20 is swingably held by the cap body 10. However, the present invention is not limited to this. An external thread may be provided on the cap body, and an internal thread adapted to this may be provided on the lid. In this case, it is more preferable to remove the flange portion 24 in the above-described embodiment and extend the peripheral wall 31 upward so that the lid member 20 is completely hidden in the circumferential direction by the slide member 30 moved to the upper position. preferable.
