  1 to 5 show a cap opening / closing device (hereinafter simply referred to as an opening / closing device) 1 for a container. 1 is an overall perspective view showing an embodiment of the switchgear 1 according to the present invention, FIG. 2 is a cross-sectional view taken along line 2-2 in FIG. 1 of the above-described embodiment, and FIG. 3 shows the switchgear of the above-described embodiment. FIG. 4 is a view showing a state of being attached to a container, FIG. 4 is a view showing a state in which an opening / closing member is locked to an opening / closing lid in a state where the opening / closing device of the above embodiment is attached to the container, and FIG. It is a figure which shows the state which open | released the cap.

  As shown in FIG. 1, the opening / closing device 1 is detachably provided in a container 50 (see FIGS. 3 and 4), and inside the container 50 is a liquid or powder such as oil, for example. Of seasonings are housed.

  A hinge cap 51 is attached to the upper end of the opening 50 </ b> A of the container 50. The hinge cap 51 is integrally formed of, for example, a synthetic resin material, and an opening / closing portion connected to the fixing portion 52 via an elastic hinge portion 54 and the fixing portion 52 inserted into the upper end of the opening 50A. And a lid 53. The fixing portion 52 and the opening / closing lid 53 are closed so as to be opened by applying a predetermined force by a fitting mechanism (not shown).

  The opening / closing device 1 includes a mounting member 10 that is detachably mounted below the hinge cap 51 in the opening 50A of the container 50, and a substantially crank-shaped swing arm 20 that is an operation lever to which the mounting member 10 is mounted. And an opening / closing member 30 provided at one end of the swing arm 20.

  The mounting member 10 includes a clamping member 11 that sandwiches and mounts the opening 50 </ b> A of the container 50. For example, the holding member 11 is formed by bending a metal spring material having a round cross section into a substantially circular shape, and an opening portion for allowing the opening 50A of the container 50 to pass from the side is formed at the tip. The open end portion 11 </ b> A of the holding member 11 has an opening size slightly smaller than the inner diameter size of the holding member 11. Therefore, when the mounting member 10 is mounted on the opening 50A of the container 50, the tip end portion 11A formed in an arc shape against the elasticity is pushed open. In addition, the said clamping member 11 is not necessarily restricted to a round cross section, A square cross-sectional shape may be sufficient.

  At the rear end corresponding to the open front end portion 11A of the clamping member 11, the bracket 12 serving as two base end portions along the outer circumference of the arc portion and at a predetermined interval is sandwiched at the arcuate central top portion. 11 protrudes outward. The two brackets 12 are formed so as to sandwich the side surface of the swing arm 20. A support shaft (hereinafter referred to as a support pin 13) is bridged between the two brackets 12, and a bolt is used for the support pin 13. In this manner, the mounting member 10 including the clamping member 11, the bracket 12, and the support pin 13 is configured. Note that the shape of the clamping member 11 is not limited to the circular shape described above. For example, it is formed in a horseshoe shape in which the distal end is open and the rear end portion is semicircular, and the distal end has an opening dimension slightly smaller than the inner diameter dimension of the clamping member 11. It is also possible to have a structure in which the open end portion of each is folded outward and formed into an arc shape.

  The swing arm 20 is formed by bending, for example, a plate member made of stainless steel having a predetermined thickness into a crank shape, and the upper end of the swing arm 20, that is, the portion facing the end of the opening 50A of the container 50 is linear. A stopper portion 20B is formed at the tip of the slide portion 20A.

  The rear end of the slide portion 20A is continuous with a curved portion 20C that is bent so as to be substantially perpendicular to the slide portion 20A. The rear end of the slide portion 20A is bent at a substantially right angle from below the curved portion 20C, and extends on the opposite side of the slide portion 20A on the extension of the bracket 12 of the mounting member 10, and this portion is connected to the pressing operation portion 20D. It has become. And the stopper part 20B is formed also in the rear-end part of this press operation part 20D.

  Such a swing arm 20 is engaged with the mounting member 10 at a position below the middle of the curved portion 20C. That is, the two brackets 12 of the mounting member 10 are supported via the support pins 13 inserted through the support pin holes (not shown) formed at positions below the middle of the curved portion 20C. A swing arm 20 is attached to 10 so as to be swingable with respect to each other. The swing arm 20 and the mounting member 10 are relatively swingable with the support pin 13 as a fulcrum. As a result, as shown in FIG. 3, when the pressing operation portion 20D of the swing arm 20 is pressed downward on the container 50 side, the opening / closing member 30 of the slide portion 20A is separated upward from the mounting member 10 side with the support pin 13 as a fulcrum. Swing. Further, by pushing up the pressing operation portion 20D, the opening / closing member 30 of the slide portion 20A swings downward toward the mounting member 10 side with the support pin 13 as a fulcrum. When the weight of the slide part 20A and the opening / closing member 30 is heavier than that of the pressing operation part 20D, the opening / closing member 30 swings downward close to the mounting member 10 side even when the pressing operation part 20D is free.

  The slide member 20 </ b> A of the swing arm 20 is provided with the opening / closing member 30. The opening / closing member 30 has two brackets erected so that both sides of the slide portion 20A are sandwiched between upper surfaces on one side of a mounting plate 31 provided with, for example, a double-sided tape 35 serving as a locking portion on the lower surface facing the top surface of the opening / closing lid 53. 32 and a support shaft 33 that is spanned between the brackets 32 and is slidable and swingably supported on the slide portion 20A. The mounting plate 31 includes the support shaft 33. It is bonded to the top surface of the opening / closing lid 53 so as to be positioned on the opposite side in the radial direction with respect to the hinge portion 54.

  The mounting plate 31 is formed of, for example, a stainless steel material, and is formed in a disk shape having a size corresponding to the opening / closing lid 53 of the hinge cap 51 having a predetermined size. As shown in detail in FIG. 2, the mounting pin 33 that is a support shaft spanned between the brackets 32 is constituted by, for example, a bolt, and the outer periphery of the mounting pin 33 is formed by a metal round pipe material. A rollable roller member 34 is inserted. The roller member 34 moves on the upper surface of the slide portion 20 </ b> A of the swing arm 20. Of course, only the pin 33 is sufficient without providing the roller member 34 on the outer periphery of the mounting pin 33. The mounting plate 31, the bracket 32, and the mounting pin 33 that constitute a part of the opening / closing member 30 may be integrally formed of plastic or the like as a whole.

  As described above, the attachment plate 31 is suspended by the attachment pin 33 and the roller member 34, and the attachment plate 31 extends along the slide portion 20 </ b> A via the attachment pin 33 and the roller member 34. It is possible to slide. The distance S (see FIG. 2) between the outer peripheral lower surface of the roller member 34 that comes into contact with the upper surface of the slide portion 20A and the mounting plate 31 swings when the swing arm 20 is swung largely upward as shown in FIG. The distance S needs to be set large in order to avoid interference between the lower surface of the arm 20 and the upper surface corner portion of the mounting plate 31. The distance S can be reduced by providing a locking groove M having a predetermined depth into which the roller member 34 is inserted corresponding to the position of the hinge cap 51 corresponding to the diameter.

  As described above, the double-sided tape 35 is provided on the lower surface of the mounting plate 31, and the mounting plate 31 and the opening / closing lid 53 of the hinge cap 51 are detachably attached to each other by the double-sided tape 35. It is like that.

  Next, a method for using the switchgear 1 having the above configuration will be described with reference to FIGS.

  As a container to be used, for example, a container 50 provided with a handle 50B on a side surface as shown in FIGS. When this type of container 50 is used, a double-sided tape 35 is affixed to the lower surface of the mounting plate 31 of the opening / closing member 30 in the opening / closing device 1, and the hinge cap 51 provided on the container 50 is attached as shown in FIG. The opening / closing device 1 is mounted on the lower side by inserting the holding member 11 of the mounting device 10 from the side surface. In addition, although a container without a handle may be used as a container to be used, in this case, it is preferable that the own weight on the slide portion 20A and the closing member 30 side is relatively heavier than that on the 20D side.

  Thereafter, the opening / closing member 30 is slid along the slide portion 20A of the swing arm 20, and the mounting plate 31 is positioned at a position facing the hinge cap 51 of the container 50. As shown in FIG. The double-sided tape 35 on the lower surface of the mounting plate 31 is attached to the upper surface of the lid 53.

  Next, as shown in FIG. 5, in a state where the user holds the handle 50 </ b> B of the container 50 with one hand, the pressing operation unit 20 </ b> D of the swing arm 20 is pressed downward toward the container 50 by the force of the thumb, for example. As a result, the slide portion 20A of the swing arm 20 swings away from the hinge cap 51 with the support pin 13 as a fulcrum.

  In this case, since the attachment plate 31 is bonded to the opening / closing lid 53 so that the support shaft 33 is positioned on the opposite side (front end side) in the radial direction with respect to the hinge portion 54, the opening / closing lid 53 is separated from the hinge portion 54. The maximum moment with the support shaft 13 as a fulcrum is obtained with respect to the support shaft 33 in the position, and the opening / closing lid 53 can be opened greatly without difficulty.

  As the opening / closing lid 53 is opened, the opening / closing member 30 slides on the slide portion 20A via the roller member 34, and the opening / closing lid 53 of the mounting plate 31 and the hinge cap 51 is opened by a predetermined angle. In this manner, in a state where the pressing operation portion 20D of the swing arm 20 is pressed, the container 50 held with one hand is tilted to pour the oil or the seasoning contained therein into the cooking ingredients. Used in.

  When the container 50 is frequently used, the opening / closing member 30 including the slide portion 20A of the swing arm 20, the mounting plate 31 and the like is pressed by merely standing the used container 50 at a predetermined position. As a result of the push-up operation, the slide portion 20A and the like return to the opening 50A side with the support pin 13 as a fulcrum, and the opening / closing lid 53 of the hinge cap 51 is lightly closed to the extent that it contacts the opening 50A. Note that a lock mechanism may be provided in the pressing operation unit 20D in order to hold the opening / closing lid 53 so that it does not open due to an unexpected fall.

  When using the container 50 in which the open / close lid 53 is lightly closed, the user grasps the grasping portion 50B of the container 50 with one hand, and the pressing operation portion 20D of the swing arm 20 with the thumb or the like. As described above, the opening / closing lid 53 of the hinge cap 51 can be easily opened simply by pressing toward the side. As a result, it is not necessary to close the cap strongly each time, and the usability is improved.

  According to the above embodiment, the following effects can be obtained.

(1) Attach the mounting member 10 to the opening 50A of the container 50, attach the opening / closing member 30 to the opening / closing lid 53 of the hinge cap 51, and then press the pressing operation portion 20D of the operating lever 20 downward on the container 50 side. For example, the operating lever 20 is swung upward with the support pin 13 as a fulcrum, and the opening / closing lid 53 of the hinge cap 51 is opened by the opening / closing member 30 accordingly. When the container 50 is frequently used, it can be easily opened and closed by the pressing action of the operation lever 20 by opening the opening / closing lid 53 that is initially tightly closed. Therefore, the hinge cap 51 of the container 50 gripped with one hand can be easily opened and closed with an operating force such as a thumb, and thus the usability is improved when the same container is frequently used.

(2) Since the opening / closing member 30 is slidable in the radial direction of the container 50 by the sliding portion 20A of the operation lever 20, the opening / closing lid of the hinge cap is different even if the size (diameter) of the head portion of the container is different. 53, and when the operation lever 20 is swung, the opening / closing member 30 slides along the slide portion 20A of the operation lever 20, so that the opening / closing lid 53 of the hinge cap 51 can be easily moved. Can be opened.

(3) Since the mounting plate 31 is bonded to the opening / closing lid 53 so that the support shaft 33 is positioned on the opposite side in the radial direction with respect to the hinge portion 54, the opening / closing lid 53 is supported at a position away from the hinge portion 54. The maximum moment with the support shaft 13 as a fulcrum with respect to the shaft 33 is obtained, and the opening / closing lid 53 can be opened greatly without difficulty.

(4) Even when the size (diameter) of the opening 50 </ b> A of the container 50 is different, the opening / closing member 30 is slid in the radial direction of the container 50, so that the opening / closing lid 53 of the hinge cap 51 can be reliably handled. As a result, even if the container 50 has a different size of the opening 50A, the single opening / closing device 1 can cope with it.

(5) Since the substantially circular sandwiching member 11 with the tip of the mounting member 10 opened is formed of a material such as elastic stainless steel, the sandwiching member 11 can be removed even if the opening 50A of the container 50 is somewhat large. By pushing in, the tip end portion 11A is expanded against the elastic force, whereby the opening / closing device 1 can be securely and firmly attached to the container.

(6) Double-sided tape 35 is affixed to the lower surface of the mounting plate 31, and the opening / closing member 30 can be easily attached to the hinge cap 51 by pressing the double-sided tape 35 against the opening / closing lid 53 of the hinge cap 51. it can.

  It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention. For example, in the above embodiment, the mounting member 10 is attached to one mounting hole of the swing arm 20 via the support pin 13 so that the swing arm 20 can swing only at one position. However, the present invention is not limited to this, and as shown in FIG. 6, the opening / closing device 1 </ b> A may be configured such that the position of the operation lever 20 can be adjusted in the height direction of the container 50. That is, for example, three mounting holes 20E are formed in the curved portion 20C of the swing arm 20, and the mounting member 10 is attached to one of the mounting holes 20E, whereby the containers 50 having different neck lengths are provided. In addition, the configuration may be such that one mounting member 10 can cope with it. According to the opening / closing device 1A having such a configuration, by adjusting the position of the swing arm 20, one device can correspond to containers having different opening lengths.

  Moreover, in the said embodiment, although it has become the substantially circular shaped clamping member 11 by which the front-end | tip of the mounting member 10 was open | released, the shape of the clamping member 11 is not restricted to this, For example, as shown in FIG. However, the mounting member 70 may include a sandwiching member 71 that is formed by bending a round bar having a predetermined diameter into a substantially rhombus shape. If comprised in this way, the effect similar to said (5) can be acquired.

  Moreover, in the said embodiment, although the double-sided tape 35 as an adhesion part is provided in the lower surface of the attachment plate 31 of the opening-and-closing member 30, it replaces with the double-sided tape 35 and is not limited to this but an adhesive agent or a magic tape, permanent. A magnet or the like may be used, or concavo-convex members that can be elastically engaged with each other may be used. In short, it is only necessary to engage with the opening / closing lid 53 of the hinge cap 51 so that the opening / closing lid 53 can be reliably opened and closed.
