By making a difference between the downward pressing portion 49 that slides inward and rises and the sealing piece 43 that fits into the sealing receiving portion 36 and does not move, the weakened connecting portion 44 that connects each other is cut, and the downward pressing portion The part 49 and the sealing piece 43 are separated.

  Further, the push button portion 42 is deformed by the push weakening portion 48, and the push button portion 42 lifts the opposite side of the hinge C of the outer peripheral lower portion 41 of the outer cylindrical wall 40 of the upper lid Ba, thereby deforming the deformed thin wall of the outer peripheral lower portion 41 in the vicinity. The portion 41a itself is deformed and bent, and the lower portion of the outer peripheral lower portion 41 is moved outward and upward.

  Further, when the push button portion 42 is pushed in, the lower end portion 49a of the lower push portion 49 is pushed inward from the outer edge of the engaging portion 35b of the opening recess 35 of the outer peripheral cylindrical portion 6 of the cap body A, and the engaging portion 35b By sliding on the inclined surface, a rising distance is added to the push button portion 42 itself and the outer peripheral lower portion 41 of the outer cylinder wall 40 connected in series, depending on the height of the inclination.

By moving the outer peripheral lower portion 41 of the outer cylindrical wall 40 outward and upward, the engagement protrusion 22 of the outer peripheral lower portion 41 of the nearby outer cylindrical wall 40 and the lid engaging cylindrical portion 5 of the cap body Aa are engaged. The engagement with the mating protrusion 9 is released and the lid is opened.
Other functions and effects are the same as those of the first embodiment.

  In this embodiment, when the push button portion 42 is first pushed, the weakening connecting portion 44 that connects the lower pressing portion 49 and the sealing piece 43 is cut and released, and therefore, once opened, the upper lid Ba is closed. Even if the lid is closed, it can be seen from the outside whether the weakened connecting portion 44 is cut or not, so that it is possible to know whether the opening is open or not, and unauthorized opening can be prevented.

  Further, since the lower recessed portion 50 is provided in the lower portion of the lower pushing portion 26 and the sealing piece 43 is continuously connected to the inner surface of the lower surface of the lower recessed portion 50 via the weakened connecting portion 44, the sharpened portion 44 is cut after the weakened connecting portion 44 is cut. This prevents the finger from hitting the cut part and prevents injury.

In Example 3, a deforming recess was formed on the opposite side of the outer peripheral hinge of the outer peripheral lower part of the outer cylindrical wall of the upper lid to form a deformed thin part that was thinner than the thickness of the peripheral wall of the other part. In the case of the lid, if the thickness is such that it can be easily deformed and bent by pushing the push button portion of the upper lid, the deformation concave portion need not be provided in order to provide the deformed thin portion.
The configuration of the outer peripheral lower portion of the outer cylinder wall of the upper lid is not limited to the form of the third embodiment.

Moreover, in Example 3, the opening recessed part recessedly provided in the outer periphery on the opposite side of the hinge of the outer peripheral cylinder part of the cap body has an outer surface extending downward from the upper end, and an engaging part inclined downward from the lower end of the outer surface. However, if the upper lid can be lifted and opened only by the deformation of the push button portion, the engaging portion does not need to be inclined, the outer surface extending downward from the upper end, and the lower push portion of the push button portion. It is good also as an engaging part of the horizontal surface engaged with a lower end part.
The configuration of the engagement portion that extends outward from the lower end of the outer surface that extends downward from the upper end of the lid opening recess of the cap body is not limited to the form of the third embodiment.

  In each of the above embodiments, the push button portion is formed so as to protrude outward from the outer cylinder wall. In consideration of appearance, the push button portion is suspended from the lower end of the outer cylinder wall, and the push button The part may be stored in the opening recess when the cover is closed, and the outer peripheral surface of the push button part may be set so as not to protrude outward from the outer periphery of the outer cylindrical wall and the outer peripheral cylindrical part.

In each of the above embodiments, the outer peripheral cylindrical portion of the cap body includes the outer cylinder, the connecting portion projecting on the opposite side of the outer cylinder hinge, and the outer sides of both of the connecting portions at a certain distance from the outer cylinder. The outer peripheral wall is provided continuously from the side, and the outer peripheral wall is provided with a hinge at the upper end of the outer periphery. The connecting portion is provided with an open recess, and when the cap is separated and discarded, the outer peripheral wall is deformed via the hinge. The outer cylinder is deformed and discarded through the connecting part. However, if the cap is configured with a simple open lid and does not need to be separated and discarded, the outer peripheral cylinder part can be used as the mouth of the cap body container. Only the cylindrical outer peripheral cylinder whose inner periphery engages with the outer periphery of the cylindrical part may be provided, and a hinge may be provided continuously at the outer peripheral upper end of the outer peripheral cylinder, and an open recess may be provided on the outer periphery on the opposite side of the hinge.
The configuration of the outer peripheral cylindrical portion of the cap body is not limited to the above embodiments.

  The present invention, when opening the hinge cap, by pushing the push button portion provided on the upper lid, it is possible to remove the fitting between the upper lid and the cap body with a simple and weak force, and to open the lid, It can be widely used as a hinge cap for various containers that can prevent unauthorized opening.
