  Since the conventional container can be easily opened by pushing down the push button, even an infant can easily open the container. Therefore, the contents stored in the container may be used wastefully, and the stored contents may be chemicals. There is also a risk of physical danger.

  In the present invention, the push button is provided with a locking device so that it is difficult for an infant or the like to open, and for an adult, the lid can be easily opened.

As a first means, a container body 1, a lid body 21 that is pivotally connected to the rear part of the container body 1 , and closes the upper surface opening 3 of the container body 1 so as to be openable and closable, and a container body 1 portion in front of the lid body 21 and a push button 41 which swing has pivoted freely before rear direction to, push in the swing around the pivot portion by the front portion of the depression of the push button 41, the push button 41 the rear part of the front lid 21 It is a container with a lid that can be opened and opened, and a shaft plate 42 is attached to the lower end of the substrate 47 suspended from the upper plate 43 of the push button 41 via a hinge 48, and both ends of the shaft plate 42 are connected to the container body. The push button 41 is slidably fitted to the container body 1 so as to be slidable rearwardly and forwardly. The locking plate 26 with 25 is suspended, and the claw plate 46 that enters and exits the through-hole 25 from the lower end of the side plate 45 that is suspended from the rear edge of the upper plate 43 of the push button 41 and slides backward on the push button 41 Sometimes the rear part of the claw plate 46 is fitted into the through hole 25 so that it cannot swing in the vertical direction, and when it slides forward, it is extracted so that it can be engaged with the lower surface of the front part of the lid 21 in front of the through hole 25. The swinging around the hinge 48 is impossible when sliding backward, and the swinging is possible only when pulled forward.

As a second means, the first means is provided, and the finger-hanging protrusion 44 is erected from the front end portion of the push button 41.

As a third means, from the front lower surface of the push button 41 which has the first or the second means, is suspended a plate spring 49 abutted to the bottom surface of the push button chamber, inclined by said front pressing The push button 41 is formed so as to be elastically returnable from the state.

By adopting the configuration of the first means , the push button 41 can be easily locked or released.

In addition, the push button can be securely locked.

By using the second means , the push button can be easily pushed or pulled out.

By using the third means , the elastic return of the push button tilted by the front pressing is facilitated.

  Referring to the drawings, reference numeral 1 denotes a container body, which has an opening 3 at the center of the top wall 2, and a lower end surface of the peripheral wall 4 is closed by a bottom lid 5. A first concave portion 6 having a narrow front portion is drilled forward from an intermediate portion in the left-right direction of the rear portion of the top wall of the container main body (right side in the figure), and the opening 3 is provided in the central portion of the first concave portion. A second recess 7 is formed, a third recess 8 as a push button chamber described later is formed at the front of the first recess, and a fourth recess 9 is formed at the rear of the first recess. A gap is provided between the second recess and the third recess, and the first hook 10 is erected from the middle portion in the left-right direction of the rear wall of the third recess 8. In addition, laterally long shaft holes 11 are formed in the inner surfaces of the left and right side walls of the third recess 8.

  A portion excluding the front portion of the first recess 6 is closed with a lid 21. As shown in FIG. 2, the lid has pins 22 projecting from the left and right sides of the rear part to the left and right sides, and these pins are fitted into shaft holes provided on the left and right sides of the first recess. The seal wall 23 is suspended by being fitted to the inner wall surface of the recess 7, and the edge protrusion 24 is inserted into the rear portion of the third recess 8 from the front end edge of the lid body, and the lower half of the lower surface of the intermediate portion in the left-right direction A locking plate 26 having a through-hole 25 is suspended from each part, and further, the second hook 27 is engaged with the first hook 10 described above from the lid plate portion behind the rim and keeps the lid closed state. Is drooping.

  In the illustrated example, the locking plate 29 that protrudes from the intermediate portion of the rear end of the lid through the hinge 28 is formed in a vertically inverted concave shape between the locking plate and the lower surface of the rear portion of the lid. A state in which the connecting plate portion of the plate spring 30 provided on the side is sandwiched, the locking plate base portion is straddled by the parallel leg-like plate portion 31 of the plate spring, and the leg-like plate portion 31 protrudes into the fourth recess 9 When the lid body 21 is rotated in the closing direction around the pin 22 from the opened state, the leaf spring 30 is shown in FIG. 1 so as to be elastically bent.

The push button 41 is slidable in the front-rear direction into the third recess 8 described above, and is not swingable in the front-rear direction around the shaft plate 42 in the rearward movement state. As shown in FIG. 2, the push button has an upper plate 43 having a front edge formed in an arc shape with a small radius of curvature and a rear edge formed in an arc shape with a large radius of curvature. By providing a recess, the upper plate portion in front of the recess is formed on the finger-hanging ridge 44, and the side plate 45 is suspended from the rear edge of the upper plate, and the nail plate 46 is protruded rearward from the lower end of the side plate. A shaft plate 42 is provided with a substrate 47 suspended at a gap therebetween, with both ends inserted into the shaft hole 11 through the hinge 48 at the lower end of the substrate, and a lower surface portion of the rear end of the recess. From the bottom, a leaf spring 49 is protruded obliquely forward, and the lower surface of the front end of the leaf spring is brought into contact with the front surface of the bottom surface of the fourth recess 9.

  The push button pushes the front surface of the finger-hanging ridge 44 rearward so that the shaft plate 42 slides backward in the shaft hole 11 and the nail plate 46 is fitted into the through hole 25 as shown in FIG. In addition, by sliding the finger-hanging protrusion 44 forward, the rear part of the claw plate 46 is extracted from the through hole 25 and engaged with the lower surface front part of the edge protrusion 24 as shown in FIG. The push button can push down the front part of the upper plate 43 against the elasticity of the leaf spring 49 at the foremost position of the push button, and the nail plate 46 is bent as a lower surface of the front end part of the lid plate by bending the hinge 48. The lower front part of 24 is pushed up to disengage the first and second hooks 10 and 27, and the leaf spring 30 shown in FIG. To do. When the front part of the lid body is pushed down from the open state, the first and second hooks are engaged and closed, and the nail plate 46 is moved to the lower surface of the front part of the edge protrusion 24 as shown in FIG. The rear upper surface touches. When the push button 41 is pushed backward from the state of FIG. 5, the shaft plate 42 advances in the shaft hole 11, and the rear portion of the claw plate is fitted into the through hole 25 as shown in FIG. In this case, the push button front part cannot be pushed down, so that the lid cannot be opened.

It is a side view which cuts and shows this invention container partially. 1 is a plan view of the container. 1 is a perspective view showing a main part of the container cut away. 3 is a perspective view showing the main part in the push button lock released state. 4 is a cross-sectional view of the main part.
