  The cap can be opened by pressing the operation part of the push piece, but because it is caused by one stable state without deformation of the elastic plate in order to maintain the closed state, the lid body It is relatively difficult to maintain a sufficient sealing property, and there is room for improvement in this respect.

  The present invention has been made in view of the above-described points. A one-touch cap that can be easily opened with one hand by pressing a pressing plate and can provide sufficient airtightness when the lid is closed. This is a proposal.

The first means is configured as follows. That is, the cap body 2, and connected via an elastic hinge mechanism A with respect to the cap body and a lid 3 which is provided openably said cap body top surface, said resilient hinge mechanism A includes a free end An elastic pressing plate that connects the lower end of the rear portion of the lid body 3 to the upper edge of the lid body 3 through a central hinge 23 and is swingably provided at the rear portion of the cap body so that the lid body in the closed state can be pushed forward. 7 and a pair of elastic plates 32 having upper ends connected to the rear surface of the lid 3 via the upper hinge 30 and lower ends connected to the rear surface of the cap body 2 via the lower hinge 31 on both sides of the elastic pressing plate. Each of the lid bodies in a first open state with an acute angle of the lid body and a wider second lid state in which each elastic plate 32 is elastically deformed by pressing the elastic pressing plate 7 from the state. It was constituted so as to maintain the stable state .

The second means is configured as follows. That, in the said first means, said lid 3 rear sides to rear sides of the cap body 2 ing provided sliding surface a sliding increase in the lid opening.

  The one-touch cap of the present invention can be opened by a simple operation of pushing in the elastic pressing plate 7, and the lid 3 is locked to the cap body 2 with a concave and convex engaging means having a high engagement strength. The lid can be easily opened even with a good sealing property.

  Further, in the case where the rear surface of the cap body 2 is provided with the sliding surface a, when the elastic pressing plate 7 is pushed in and the engagement of the lid body 3 with the cap body 2 is released, Even if the urging force is weak, the lid 3 can be reliably rotated by the contact between the lid 3 and the sliding surface a.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The one-touch cap 1 of the present invention includes a cap main body 2 and a lid 3 that is connected to the main body via an elastic hinge mechanism A so that the upper surface of the cap main body can be opened and closed.

  The cap body 2 is attached to the mouth / neck portion of the container body. In the illustrated example, the cap body 2 has a cylindrical shape with a lower end opening extending from the peripheral wall 4 to the upper center of the rear portion of the peripheral wall 4. A concave recess 6 for operation is formed, and an elastic pressing plate 7 is erected on the rear edge of the recess. Further, a belt-like fitting recess 8 is provided that extends vertically through the center of the top wall 5 from the front upper end of the peripheral wall 4 and reaches the operation recess 6. The fitting recess 8 is wider than the operation recess 6, and the fitting recess inner wall portion on both sides of the operation recess 6 is configured as a sliding surface a on which the rear lower end of the lid 3 slides. Further, a swing outlet 9 is drilled in the front portion of the top wall in the fitting recess 8, and the lid 3 is formed on the front surface of the lid, which is the back wall portion of the fitting recess 8 in the rear portion of the peripheral wall 4. A locking projection 10 is provided for locking. Further, a thread 11 for screwing the container body or the like around is provided around the inner peripheral lower portion of the peripheral wall 4.

  The lid 3 is provided so as to close the upper surface of the main body so as to be openable and closable. In the illustrated example, the front hanging wall portion 21 and the rear hanging wall portion 22 are suspended from the front and rear edges of the rectangular top plate portion 20, respectively. The rear end is extended to the rear part of the operation concave part 6 by being fitted in the fitting concave part 8, and the central part of the lower end edge of the rear hanging wall part 22 is interposed through the central hinge 23. The elastic pressing plate 7 is connected to the upper end edge. Further, the engaging projection 24 projecting from the inner surface of the front hanging wall portion 21 is configured to be able to ride over and engage with the locking projection 10 of the main body. Further, a rod plug 25 suspended from the back surface of the top plate portion 20 is configured to be fitted to the swing outlet 9.

  The elastic hinge mechanism A is connected to the upper edge, which is a free end, via the central hinge 23, and the rear lower end of the lid 3 is swingably provided at the rear of the cap body 2 to the front of the closed lid 3. The elastic pressing plate 7 that can be pushed out, and the upper end of the pressing plate on both sides of the pressing plate are connected to the rear surface of the lid 3 via the upper hinge 30 and the lower end is connected to the cap body 2 via the lower hinge 31. And a pair of elastic plates 32 connected to the rear surface.

  Further, the elastic hinge mechanism A opens the elastic plate 32 while elastically deforming each elastic plate 32 by pressing the elastic pressing plate 7 from the acute first open state of the lid body 3 as shown in FIG. As shown in FIG. 3, it is configured such that the stable state of the lid 3 is maintained in the wider second lid open state.

  That is, in the first open state shown in FIG. 2, each elastic plate is not elastically deformed or hardly elastically deformed as shown in FIG. 4 (a). The lid 3 is in a stable state by supporting the sharp open state by 32. Therefore, when the lid 3 is closed from this state, each elastic plate 32 is elastically deformed as shown in FIG. 4 (b). It is energized to return to the original state. Similarly, when it is rotated in the opening direction within a predetermined angle range, it is urged to return to the original state. Therefore, in the state where the lid 3 is closed from the first open state and the engaging projection 24 is moved over the engaging projection 10 and engaged, the lid 3 is always urged in the opening direction.

  Further, in the second open state, the elastic pressing plate 7 is pushed in to further open the cover 3 in the first open state, so that the cover is wider than that, specifically, the contents can be taken out. It has been migrated. When the elastic pressing plate 7 is pushed in, the central hinge 23 moves forward, and the lid 3 is further opened by the support of the elastic plates 32 connected to the upper and lower sides of the central hinge 23. In the (2 lid open state), as shown in FIG. 4 (c), the forces of the elastic plates 32 and the elastic pressing plates 7 are balanced to maintain a stable state in that state.

  In the illustrated example, the lid 3 exhibits a lid opening angle of about 15 ° in the first opened state and a lid opening angle of about 90 ° in the second opened state. By selecting the length, shape, specific mounting position of each upper and lower hinge, etc., the opening angle can be appropriately selected.

  In the one-touch cap configured as described above, when the elastic pressing plate 7 is pushed in from the state of FIG. 1, the central hinge 23 portion moves forward to push the lid 3 forward, and the engagement protrusion 24 of the lid 3 is the cap. It comes off from the locking projection 10 of the main body 2. At this time, since the lid 3 is biased in the opening direction, it automatically opens to the first opened state. Further, in the illustrated example, when the elastic pressing plate 7 is pushed in, the rear lower end of the lid 3 abuts against the sliding surface a so as to slide up. Even if it is weak, the lid can be opened more reliably with the contact portion as a fulcrum. Next, when the elastic pressing plate 7 is still pushed in, the lid 3 stops opening to the second open state as described above. In the case of the actual opening operation, the elastic pressing plate 7 can be continuously moved to the second opening state by pushing it in at a stroke. When the lid 3 is closed, for example, the lid 3 may be rotated by a finger or the like so that the engaging protrusion 24 is moved over the engaging protrusion 10 and engaged.

  In addition, although each figure of the said embodiment is drawn as if it was formed integrally for convenience in explaining for easy understanding, in practice, for example, the lid 3, the elastic pressing plate 7, the elastic hinge mechanism A for convenience of molding. The cap main body 2 can be formed by a method in which a part of the cap body 2 is separately formed integrally with a synthetic resin and assembled to another part formed of the synthetic resin.
