The vertical plate portions are vertically suspended and the lower end portions of these vertical plate portions are connected by a horizontal plate portion, and the swing plate portion is projected obliquely rearward from the lid plate portion located between the vertical plate portions. The lower end of the elastic reversal plate portion extended from the lower end of the swing plate portion is connected to the upper surface of the horizontal plate portion. In addition, a thin third and fourth hinge portions are attached to the connecting portion between the swing plate portion and the elastic reversing plate portion and the connecting portion between the elastic reversing plate portion and the horizontal plate portion, respectively, and the rear portion of the lid plate By pressing down, the elastic reversal plate portion is provided so as to be elastically reversible forward.
[0003]
Moreover, like the cap described in Japanese Utility Model Publication No. 62-200565, a pouring hole is provided in the central portion of the top wall, and an upward leg surrounded by a U-shaped notch is provided on the upper surface near the front portion. In addition, an outer peripheral wall is provided in the outer periphery of the mounting peripheral wall, and a pressing plate is formed by a notch extending from both sides of the notch to the lower end of the front wall of the outer peripheral wall as a thin flexible hinge between the notches. A cap body provided with one engaging projection of a clasp on the upper front surface of the plate, and a projecting plug inserted into the pouring hole from the back surface are suspended, and the rear end is pivotally attached by a hinge.

[0004]
In the former case, by pushing the rear part of the cover plate downward, the elastic reversal part is reversed forward to maintain the cover plate in the open state, and from that state, the front part of the cover plate is pushed downward. The elastic reversal plate part is configured to be able to reverse and maintain the original closed state. In the latter case, the engagement protrusion of the push plate and the open / close lid are engaged by pushing the push plate. The engagement with the protrusion is released, the opening / closing lid is opened by the urging force of the drive spring to maintain the opened state, and the opening / closing lid is pressed and rotated from this state to engage each of the engagement protrusions. It is configured to be able to maintain the closed state.
[0005]
[Problems to be solved by the invention]
These can keep the lid open, the lid does not get in the way of dispensing the contents, and can be opened simply by pressing the lid plate or push-in plate. It is an excellent one.
[0006]
However, these still have room for improvement.
That is, in the former case, the elastic reversal plate part acts from the middle of opening the lid so that the angle for rotating the lid is small, but since the pressing part is the top surface of the lid, opening and closing while holding the container is performed. It ’s stupid. On the other hand, the latter can be easily opened by pushing the push-in plate while holding the container with one hand, but when closing the lid, the upper surface of the lid must be pressed, so the container was held with one hand. The operation in the state is difficult to perform, and since a small member such as a torsion spring is used, there is a disadvantage that the assembling operation becomes complicated.
[0007]
The present invention proposes an excellent cap that can open and close the lid more easily than the conventional one, and that can be easily assembled with a relatively simple structure.
[0008]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The cap 1 of the present invention includes a cap body 2, a lid plate 3, a pressing plate 4, and an elastic connecting plate 5.
The cap body 2 has a cylindrical shape with an opening at the lower end surface extending from the upper end edge of the peripheral wall 6 and has a through hole 8 communicating with the mouth of the container body attached to the front portion of the top wall 7. A concave portion 9 having an open upper surface and a rear surface is provided in the rear portion.
[0010]
In the present embodiment, the concave portion 9 is configured by forming the front portion of the parallel side wall 9a slightly wider via the stepped portion 10 facing forward, and curving the lower portion of the front wall 9b to connect to the horizontal bottom wall 9c. In addition, a pair of fitting recesses 11 for fitting the top plate are formed by denting the left and right top walls from both sides of the recess 9 to the bottom wall 9c level. A plurality of the through holes 8 are formed in the top wall 7 in front of the recess 9.
[0011]
Further, the lid plate 3, the pressing plate 4, and the elastic connecting plate 5 are integrally formed.
The cover plate 3 is pivotally attached to the upper part of the inner surface of the both side walls 9a of the recess 9 on both sides of the rear end portion, and is provided so as to be able to close and open the through hole 8. In this embodiment, the wide portion of the concave portion 9 and the top wall 7 in front of the concave portion 9 are covered, and pivoting shafts 13 are projected from both sides of the hanging plate 12 suspended from both sides of the lower surface of the rear end portion. A shaft 13 is rotatably fitted to a bearing 14 drilled above the rear portion of the wide portion of the recess 9 so as to be opened and closed. In addition, a rod plug 15 that fits in correspondence with each through-hole 8 is suspended from the back surface. Each of the bearings 14 is configured such that a guide groove 16 is provided above the bearing 14 so that the pivot shaft 13 can be fitted from above the cap body via the guide groove 16.
[0012]
The pressing plate 4 is pivotably attached to the inner surface of the rear end of the side wall of the recess 9 so as to be pivotable in the vertical direction on both sides. In the present embodiment, a box shape having an opening at the lower end is formed, and a pair of pivot shafts 17 projecting from the vertical center portions on both front end portions are provided with bearings 18 provided in the center portions on both rear and vertical portions of the concave portion 9. Each is fitted so as to be rotatable. Each of these bearings 18 is also provided with a guide groove 19 similar to the above-described bearing 14 so that it can be fitted and mounted from above. Further, a locking projection 20 is provided so as to project upward from the rear end portion of the upper surface.
[0013]
The elastic connecting plate 5 protrudes obliquely upward from the central portion of the front surface of the pressing plate 4 and is connected to the rear end edge of the lid plate 3 via a thin hinge 21 so as to be bent. In this embodiment, the elastic connecting plate 5 is slightly curved downward so that elastic deformation can be easily performed, and the elastic connecting plate is attached to the lower end edge of the plate-like protrusion 22 suspended from the rear center of the lid plate via a thin hinge 21. 5 The tip is connected.
[0014]
Further, the position at which the lid plate 3 and the connecting rod 5 are connected by the thin hinge 21 is shifted upward from the plane connecting the shaft centers of the pivot shafts 13 and 17, When the upper portion of the pressing plate 4 is pushed in, the elastic connecting plate 5 is rotated while being elastically deformed so that the cover plate 3 stands upside down.
The inverted standing of the cover plate 3 here means that the cover plate 3 which is in a closed state and is in a stable state is urged toward the closing direction by the elastic part connected in the first half of the rotation, and in the second half of the rotation. In the elastic reversing mechanism that is biased in the opening direction and maintains a stable state at a predetermined opening angle, it means a state in which the opening of the cover is raised.
[0015]
The top plate 23 is configured to be fitted and fixed to the upper surface of the cap body 2. The top plate 23 has a disk shape with a notch 24 formed in the center of the front part, and is configured to close the upper surfaces of the left and right fitting recesses 11 and the narrower part upper surfaces of the recesses 9. A fitting protrusion 25 is vertically provided to be fitted to the upper end of the inner surface of the cap body peripheral wall 6 that is the arcuate side wall of the fitting recess 11.
[0016]
In the cap 1 configured as described above, when the upper portion of the pressing plate 4 is pushed forward from the state shown in FIG. 2, the connecting plate 5 rotates around the axis of each pivot shaft 17, and accordingly the lid plate 3. Rotates about the axis of each pivot shaft 13. At this time, the connecting plate 5 is rotated in a state of being elastically deformed, and the elastic plate 5 acts to close the lid while the thin hinge 21 reaches from the point A in FIG. The cover plate 3 is urged, and the cover plate 3 is urged in the direction of opening the lid from the substantially middle point to the point B. When the thin hinge 21 moves to the point B, the elastic plate 5 is elastically restored to the original state, and the cover plate 3 is maintained in a stable state. In this case, the pressing plate 4 is naturally maintained in a forward inclined state.
[0017]
Further, by pushing the lower part of the pressing plate 4 from the open state of the cover plate 3, the cover plate 3 is reversed and closed by the same action as described above, and then becomes stable again.
In the above embodiment, one elastic connecting plate is provided at the central portion of the center portion in the vertical direction of the front surface of the pressing plate. However, as shown in FIG. The connecting plates 5 and 5 may be extended. In this case, for example, although not shown, the front ends of the connection plates 5 and 5 are integrally connected to the lower surfaces of a pair of plate-like protrusions suspended from both sides of the rear end of the lid plate via thin-walled hinges. The configuration is the same as in the above embodiment. Further, all the above members are preferably formed of synthetic resin.
【The invention's effect】
