The thinnest part (the thinnest part O) has a tapered shape that gradually increases in thickness, and is connected to the substantially cylindrical button part 102B with a predetermined thickness. Further, the rear end portion 102C of the pressing portion 102 connected to the cylindrical portion 106 has a substantially step shape in a sectional view, and is thinner than the cylindrical portion 106 and the button portion 102B.

  Thus, when the button portion 102B is pressed with the container held by hand (in the direction of arrow A), the pressing portion 102 is loaded with a rotational moment with the thinnest portion O of the tip portion 102A as a fulcrum. The end portion 102C is bent and deformed as shown in FIG. 7B, and the rear side sinks downward.

That is, the direction in which the button part 102B is pressed (arrow A direction) and the deformation direction of the button part 102B (arrow B direction) are reversed. For this reason, it is difficult to operate the button portion 102B, and the holding of the container is hindered by the button operation.

  Hereinafter, a cap according to an embodiment of the present invention will be described with reference to the drawings.

  1 and 2 show a substantially cylindrical cap 10 made of synthetic resin. A female groove 16A (see FIG. 3) is formed on the inner peripheral surface of the cap body 16, and is formed in the mouth (not shown) of the container 12 (see FIG. 5) filled with liquid seasoning such as chili oil. The male groove is screwed to cover the mouth.

  On the upper surface of the cap main body 16, a lid engaging step portion 24 is projected so as to leave the hook portion 22 on the outer peripheral portion, and a cylindrical portion 26 is formed at the center of the lid engaging step portion 24. A nozzle-like spout 28 protrudes obliquely upward from the cylindrical portion 26, and a pressing portion 30 is provided on the upper portion of the cylindrical portion 26.

  And between the spout 28 and the press part 30, the partition part 40 (after-mentioned) which divides the spout 28 and the press part 30 is standingly arranged from the upper surface of the lid | cover engagement step part 24. As shown in FIG.

  By the way, the pressing portion 30 is provided on the opposite side of the substantially domed button portion 46, the substantially step-like elastic crush portion 48 provided around the button portion 46 on the spout 28 side, and the spout 28. Hinge part 50.

  The button part 46 is formed in a substantially oval shape from the hinge part 50 toward the spout 28 in a plan view (see FIG. 4), and from the hinge part 50 in a side view (see FIG. 5). It gradually increases toward the 28th side.

On the other hand, as shown in FIG. 3, the elastic crushing portion 48 includes an upper annular wall 48A that is connected to the base of the button portion 46, a lower annular wall 48B and an upper annular wall that are disposed at a position one step lower than the upper annular wall 48A. The upper annular wall 48A, the lower annular wall 48B, and the vertical wall 48C are thinner than the cylindrical portion 26. Further, an upper annular wall 48A and a lower annular wall 48B is a thickness substantially the same as the vertical wall 48C, the width of the upper annular wall 48A (W ₁₎ and the width of the lower annular wall 48B (W ₂₎ is The vertical wall 48C is larger than the height (H).

  Further, the height of the vertical wall 48C is gradually increased from the hinge portion 50 to the elastic crushing portion 48. In the hinge portion 50, the upper annular wall 48A and the lower annular wall 48B are substantially flush with each other. Yes. Further, the hinge part 50 is formed on a substantially straight line along a direction orthogonal to the direction in which the liquid is poured out from the spout 28, and the lower annular wall 48 </ b> B and the cylindrical part are formed on the back side of the hinge part 50. A fall prevention wall 52 is formed at the boundary portion 26 in parallel with the hinge portion 50.

  On the other hand, as shown in FIG. 1, a pair of connecting pieces 32 protrude at a predetermined interval on the left side of the cap body 16 in the figure with the protruding side of the spout 28 as the front, and at the center in the longitudinal direction. Is provided with a thin hinge portion 32A, which allows the connecting piece 32 to be bent. Between the connecting pieces 32, an elastic piece 38 to be described later is provided. A disc-shaped lid 34 is coupled to the tip of the coupling piece 32 so that the upper surface of the cap body 16 can be opened and closed (in the drawings other than FIGS. 1 and 2, the lid 34 is illustrated for convenience. Omitted).

  The inner diameter of the lid 34 is formed to be slightly larger than the diameter dimension of the lid engaging step portion 24, and can be locked by being fitted to the lid engaging step portion 24 when the lid 34 is closed. Yes. Further, a flange 36 is provided on the outer peripheral edge of the lid 34 facing the hinge portion 32 so as to hook a finger when the lid 34 is opened.

  As shown in FIGS. 1 and 2, the lid 34 and the cap body 16 are provided with the above-mentioned elastic piece 38 formed by cutting out a part of the lid 34 and the cap body 16 (between the hinge portions 32). Yes.

  The elastic piece 38 has a thin plate shape and a substantially middle portion in the longitudinal direction (opening / closing direction of the lid 34) is bent at a substantially right angle, and both ends are separated (or returned) with the opening / closing operation of the lid 34 and elastically deformed. The structure is such that an urging force is generated on the lid 34.

  In this case, the elastic force accumulated in the elastic piece 38 is maximized at a substantially middle point of the operating range of the lid 34. When the lid 34 moves in the opening or closing direction with the intermediate point as a boundary, the moving speed is accelerated by the urging force (restoring force) of the elastic piece 38, and the elastic piece 38 is restored at a predetermined position. Is retained.

  On the other hand, on the front side of the inside of the lid 34 (on the side of the spout 28), the auxiliary wall portion 42 that slidably contacts the wall surface of the partition wall portion 40 described above with the lid 34 covering the upper surface of the cap body 16 is erected. Yes.

  First, the partition 40 on the side of the cap body 16 will be described. The partition 40 is formed in an orientation along the opening / closing direction of the lid 34 that operates via the hinge 32 and crosses the upper surface of the cap body 16. Thus, the width of each side end portion reaches the outer periphery of the lid engaging step portion 24, and the height is such that a small gap is formed between the lid 34 and the inner surface of the lid 34 when the lid 34 is completely closed. Yes.

  On the other hand, the auxiliary wall portion 42 provided on the lid 34 is in a direction along the opening / closing direction of the lid 34, that is, parallel to the partition wall portion 40, and the pressing portion of the partition wall portion 40 is closed. It is formed at a position in sliding contact with the wall surface on the 30 side, and both end portions are connected to the peripheral wall of the lid 34 across the inside of the lid 34.

  At the center in the width direction of the auxiliary wall portion 42, a rectangular cutout 44 is formed as a relief to prevent the upper surface of the auxiliary wall portion 42 from contacting the cylindrical portion 26 when the lid 34 is closed. The height of the wall portions located on both sides of the notch 44 is such that a small gap is formed between the wall portion and the lid engaging step portion 24 in a state where the lid 34 is completely closed.

  For this reason, when the lid 34 of the cap 10 is fitted to the lid engaging step portion 24 of the cap body 16 and completely closed, the peripheral edge 34A of the lid 34 abuts against the hanging portion 22 and the upper surface of the cap body 16 is almost the same. As a result, the spout 28 is closed by the peripheral wall of the lid 34 and liquid leakage is prevented.

  In this state, the upper space of the cap body 16 covered with the lid 34 is divided into the pressing portion 30 side and the spout 28 side by the partition wall portion 40 and the auxiliary wall portion 42. It does not flow into the pressing part 30 side.

  For this reason, even if the container 12 is shaken to stir the seasoning in the container 12, the residual liquid that tries to flow into the pressing part 30 from the vicinity of the spout 28 is blocked by the partition wall 40 and the auxiliary wall part 42. As a result, the liquid is prevented from adhering to the pressing portion 30, and the pressing portion 30 is not contaminated by the liquid.

  In addition, even when the lid 34 is twisted in a closed state, a resistance force against the twisting force is generated by the contact between the partition wall 40 and the auxiliary wall portion 42. The partition wall 40 and the auxiliary wall 42 have a large contact width (area) across the upper surface of the cap body 16 and the inside of the lid 34, thereby increasing the resistance to twisting. Therefore, the load applied to the hinge part 32 due to the twisting force is greatly reduced, and the damage of the hinge part 32 is less likely to occur.

  Next, the operation of the cap 10 according to the present embodiment will be described.

  As shown in FIGS. 1 and 2, the pressing portion 30 is provided with an elastic crushing portion 48 on the spout 28 side and a hinge portion 50 on the opposite side of the spout 28. Thereby, the elastic crushing part 48 and the spout 28 are located on the same side of the pressing part 30. Therefore, as shown in FIGS. 5 and 6A to 6C, when the button portion 46 is pressed (in the direction of arrow A), the pressing portion 30 rotates around the hinge portion 50 (in the direction of arrow B). ) And the elastic crushing portion 48 is elastically deformed.

  Thereby, the button part 46 sinks and the inside of the container 12 is pressurized. At this time, when the container 12 is tilted with the spout 28 facing downward, the liquid that has moved to the cap 10 side is poured out from the spout 28. When the pressing force to the button portion 46 is released, the pressing portion 30 is restored to the original state by the restoring force of the elastic crushing portion 48 (see FIG. 6A), and the next dispensing operation can be performed. .

  By the way, when the button part 46 is pressed, it is normally pressed with a fingertip so that a force enters the spout 28 side. At this time, a force in the direction of arrow A is applied to the button portion 46, and the elastic crushing portion 48 located on the side of the spout 28 of the pressing portion 30 is elastically deformed in the direction of arrow B around the hinge portion 50, thereby The inside is pressurized and liquid is poured out from the spout 28.

  In other words, in the present invention, in the pressing part 30, the side on which the force is applied by the fingertip is elastically deformed, so the direction in which the force is applied by the fingertip (arrow A direction) and the pressing part 30 are elastically deformed. The direction (arrow B direction) is the same. For this reason, the button part 46 can be operated without a sense of incongruity, and operability is good.

  Further, the elastic crushing portion 48 is provided in a substantially staircase shape, and the height of the vertical wall 48C is gradually increased from the hinge portion 50 to the elastic crushing portion 48. In the hinge portion 50, the upper annular wall 48A and the lower annular wall are provided. 48B is substantially flush.

  This makes it difficult to elastically deform the hinge portion 50 side and facilitates elastic deformation of the elastic crushing portion 48 side. Further, by providing the elastic crushing portion 48 in a substantially step shape by the upper annular wall 48A, the vertical wall 48C, and the lower annular wall 48B, for example, as compared with the case where only one annular wall is elastically deformed, it is accumulated by pressing. The elastic force can be increased.

  For this reason, the restoring force of the elastic crushing part 48 can be increased, and after pressing the button part 46, the shape of the pressing part 30 can be restored immediately. That is, since the liquid accumulated in the spout 28 is immediately sucked back into the container 12, the liquid poured out from the spout 28 is easily cut and does not easily leak.

Further, as shown in FIG. 6A, the upper annular wall 48A, the lower annular wall 48B, and the vertical wall 48C have substantially the same thickness, so that an appropriate rigidity and stability during operation of the button portion 46 are achieved. Sex can be obtained. Furthermore, the width dimension of the width (W ₁₎ and a lower annular wall 48B of the upper annular wall 48A (W _2), is made larger than the height of the vertical wall 48C (H), FIG. 6 (B), ( C), the upper annular wall 48A and the lower annular wall 48B are more easily elastically deformed than the vertical wall 48C, and the operability of the button portion 46 is improved.

  Further, as shown in FIG. 4, the button portion 46 is formed in a shape corresponding to the shape of the fingertip by applying a substantially oval shape from the hinge portion 50 to the elastic crushing portion 48. Easy to press.

  Moreover, the hinge part 50 is formed along the direction orthogonal to the direction which the liquid pours out from the spout 28, and when the button part 46 is pressed, the press part 30 does not incline in the left-right direction. be able to.

  Further, as shown in FIG. 3, by providing a fall prevention wall 52 on the back side of the hinge portion 50, the rigidity on the hinge portion 50 side is increased, and the pressing portion 30 is reliably prevented from falling in the left-right direction and pressed. A sense of stability when pressing the portion 30 is improved.

  In addition, this form is an Example to the last, and it cannot be overemphasized that it can change suitably in the range which does not deviate from the main point of this invention. In the present invention, the direction in which the button 46 is pressed and the direction in which the elastic crushing portion 48 is elastically deformed need only be substantially the same. Therefore, the shape of the button 46 or the shape of the elastic crushing portion 48 is not limited thereto. .

  For example, the elastic crushing portion 48 has a stepped shape and is composed of an upper annular wall 48A, a lower annular wall 48B, and a vertical wall 48C that connects the upper annular wall 48A and the lower annular wall 48B, but is required when the button portion 46 is pressed. Depending on the elastic force, etc., it is not always necessary to be stepped.

  Further, in the upper annular wall 48A, the lower annular wall 48B, and the vertical wall 48C, the thickness, width dimension, and the like may be changed depending on the location and order of elastic deformation. For example, when the thickness of the upper annular wall 48A and the lower annular wall 48B is made thinner than the vertical wall 48C, the elastic crushing portion 48 can be more easily elastically deformed. This leads to an improvement in the operability of the unit 46.

  Furthermore, in the present invention, the cap body 16 and the lid 34 are connected and integrally provided via the hinge portion 32. However, the cap body 16 and the lid 34 are not necessarily integrated and may be provided separately. Of course, the present invention may be used as a cap for cosmetics and shampoos other than liquid seasonings.
