[0004]

[Problems to be solved by the device]

 By the way, when opening the lid A, the upper surface of the lid body 1 is pressed down and then the hanging wall 2 is raised upward. The force of pressing against and the force of causing the hanging wall 2 to act upward act, that is, the forces that face in opposite directions act on each other, and these forces cancel each other out, and the force to open the lid A is effective. There is a problem that it is difficult to open the lid A because the lid A has to be rolled up while being bent. The present invention has been made in view of the above circumstances, and an object thereof is to provide a container lid that can be easily opened.

[0005]

In order to achieve the above-mentioned object, a lid of a container according to claim 1 of the present invention comprises a flat plate-shaped lid body, and a lid body extending downward from an outer peripheral portion of the lid body. The lower end is formed with a hanging wall formed with a protrusion that fits into the flange portion, and a slit is formed in a part of the outer peripheral portion of the lid body along the outer periphery of the lid body.

Further, the lid of the container according to claim 2 is the lid of the container according to claim 1, in which a bridge portion which is torn off when the lid is opened is formed between the wall portions forming the slits.

Further, the container lid according to claim 3 is the container lid according to claim 1 or 2, wherein a hook portion protruding from the hanging wall is formed on the hanging wall on the side where the slit is formed. It is a thing.

[0008]

[0011]

【Example】

 An embodiment of the container lid of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment. The lid C of the container shown in these figures is mainly different from the above-mentioned conventional lid A in that the slit 10 is formed in the lid main body 1. Therefore, this point will be described and other same components will be described. Are denoted by the same reference numerals and the description thereof is omitted.

That is, on the outer peripheral portion of the lid body 1, the slits 10 are formed along the outer periphery of the lid body 1 at regular intervals from the outer peripheral edge. The slit 10 has a length that is about half the outer peripheral portion of the lid body 1, and the line segment connecting both ends thereof is located on the diameter of the lid body 1. The slit 10 is formed by penetrating the lid main body 1. The portion on the outer peripheral side of the slit 10 is a fixing piece 11 fixed to the flange portion 5 of the container B, and the portion on the inner peripheral side is It is a movable piece 12 that can be slightly rotated up and down.

In addition, at a central portion in the circumferential direction of the hanging wall 2 on the side where the slit 10 is formed, a handle portion projecting from the hanging wall 2 to the outside in the radial direction of the lid body 1 in a semi-disc shape. 13 are formed. When the lid C is unsealed, a finger is hooked on the handholding portion 13 and pulled upward so that the lid C can be easily unsealed.

To remove the lid C having the above-mentioned configuration from the container B, the upper surface of the movable piece 12 is pressed and then the handle portion 13 is raised upward. Then, the fixing piece 11 rises upward together with the handle portion 13. At this time, the movable piece 12 comes into contact with the flange portion 5 at the mouth of the container B, and receives a force for pressing the movable piece 12 downward by the flange portion 5. On the other hand, the force that causes the handhold 13 to move upward acts on the fixing piece 11 via the hanging wall 2, and the fixing piece 11 rotates upward together with the hanging wall 2 and rises. Therefore, the force that causes the handhold 13 to move upward is not canceled or is less likely to be canceled by the force that presses the movable piece 12 downward, so that the force for opening the lid A effectively acts. Moreover, since a gap is formed between the fixed piece 11 and the movable piece 12 by the slit 10, the projection 4 is easily opened to the outside and easily detached from the flange portion 5 of the container B. When the fixing piece 11 rises up to some extent, the lid C rises up around a portion that is separated from the handhold portion 13 by 180 ° in the circumferential direction as a spindle, and is completely removed from the container B.

Therefore, according to the lid C having the above-described configuration, when the lid C is opened, the force that causes the handle portion 13 to move upward is not canceled by the force that presses the movable piece 12 downward, or is less likely to be canceled. Therefore, the force of opening the lid C effectively acts, and the projection 4 is easily opened outward by the slit 10 and easily comes off from the flange portion 5 of the container B. Since it is not necessary to roll up the entire lid while bending it, the lid C can be easily opened. Further, since the handle portion 13 is provided, the force at the time of opening the lid C acts on the fixing piece 11 reliably and in a well-balanced manner, so that the opening can be performed more easily.

FIG. 3 shows a second embodiment. The main difference between the lid D shown in this figure and the lid C of the first embodiment is the shape of the slit. That is, a pair of slits 15 and 15 are formed along the outer periphery of the lid body 1 at a constant distance from the outer peripheral edge of the lid body 1. Each slit 15 is formed to be slightly shorter than a half of the outer peripheral portion of the lid body 1, and a bridge portion 16 is formed between the wall portions at the ends of the slits 15, 15 which are circumferentially adjacent to each other. The bridge portion 16 is formed on the side where the lid D starts to be opened, that is, on the side where the handle portion 13 in the first embodiment is formed, and is formed into a thin enough to be torn off when the lid is opened. Has been done.

The slits 15 and 15 are formed so as to penetrate through the lid body 1, and a portion on the outer peripheral side of the slits 15 and 15 is a fixing piece 11 fixed to the flange portion 5 of the container B. A portion on the inner peripheral side is a movable piece 12 which can be slightly rotated up and down. Further, a portion that is separated from the bridge portion 16 by 180 ° in the circumferential direction is a connecting portion 17 that is much wider than the bridge portion 16, and the movable piece 12 is connected to the fixed piece 12 by the connecting portion 17.

To remove the lid D having the above structure from the container B, the upper surface of the movable piece 12 is pressed and then the hanging wall 2 on the side where the bridge portion 16 is formed is raised upward. Then, the bridge portion 16 is torn off by this pulling force, and the fixing piece 11 rises up. In this case, the fixed piece 11 rotates about the outer peripheral side of the connecting portion 17 as an axis. Further, the projections 4 are easily opened to the outside by the slits 15 and 15 and easily come off from the flange portion 5 of the container B. When the fixing piece 11 rises to some extent, the lid D is completely removed from the container B. On the other hand, in order to attach the lid D to the container B again, after engaging a part of the protrusion 4 at the lower end of the hanging wall 2 with the flange portion 5 and pressing the fixing piece 11, the remaining protrusion 4 is flanged. This is done by engaging the part 5.

Therefore, according to the lid D having the above-described configuration, when the lid D is opened, the force that causes the hanging wall 2 to move upward pushes the movable piece 12 downward, as in the first embodiment. Since it is not canceled or is not easily offset by the force of opening, the force of opening the lid D effectively acts, and the projections 4 are easily opened to the outside by the slits 15 and 15, so that the flange portion 5 of the container B can be easily opened. Since it can be easily removed from the lid, the lid D can be easily opened without the need to roll up the entire lid while bending it as in the conventional case. Moreover, since the lengths of the slits 15 and 15 are longer than that of the slit 10, there is an advantage that the lid D can be opened with a force smaller than that of the lid C of the first embodiment. Further, since the bridge portion 16 is torn off when the lid D is opened, it is possible to obtain a virgin effect of the lid, that is, it is possible to prevent unauthorized use of the lid.

In the second embodiment described above, the handle portion 13 may be provided on the hanging wall 2 of the lid D as in the first embodiment. When the handle portion 13 is provided, the force at the time of opening the lid D acts on the fixing piece 11 in a reliable and balanced manner, and the opening can be performed more easily.

FIG. 4 shows a third embodiment. The main difference between the lid E shown in this figure and the lid D of the second embodiment is the shape of the slit. That is, a pair of slits 20, 20 are formed along the outer periphery of the lid body 1 at a constant distance from the outer peripheral edge of the lid body 1. Each slit 20 is formed to be shorter than a half of the outer peripheral portion of the lid body 1, and between the slits 20 and 20 adjacent to each other in the circumferential direction, the connecting portions 21 and 21 having substantially the same width as the connecting portion 17 of the lid D are formed. By these connecting portions 21 and 21, the movable piece 12 on the inner peripheral side is connected to the fixed piece 11 on the outer peripheral side of the slits 20 and 20 so as to be slightly rotatable vertically.

Further, a bridge portion 22 is formed in the central portion of each slit 20 between the wall portions forming the slit 20. Like the bridge portion 16, the bridge portion 22 is provided on the side where the lid E starts to be opened, that is, on the side where the handle portion 13 in the first embodiment is formed and the side facing the handle portion 13. It is formed and has a thinness that allows it to be torn off when opened.

To remove the lid E having the above-described configuration from the container B, the upper surface of the movable piece 12 is pressed and then the hanging wall 2 on the side where the one of the bridge portions 22 is formed is raised upward. Then, one bridge portion 22 is torn off by this pulling force, and the fixing piece 11 rises upward. In this case, the fixed piece 11 rotates about the connecting portions 21, 21 as an axis. At this time, since the connecting portions 21, 21 are slightly twisted, this causes the other side portion of the movable piece 12 to rotate slightly downward. Then, the other bridge portion 22 is torn off. Further, the slit 20 makes it easier for the protrusion 4 to open to the outside, and is easily detached from the flange portion 5 of the container B. Then, when the fixing piece 11 rises to some extent, the lid E is completely removed from the container B.

Therefore, according to the lid E having the above-described structure, the force that causes the hanging wall 2 to move upward when opening the lid E causes the movable piece 12 to move, as in the first and second embodiments. Since it is not canceled or is not easily offset by the force of pressing downward, the force of opening the lid E acts effectively, and the protrusion 4 is easily opened to the outside by the slit 20, and the flange of the container B is easily opened. Since it can be easily removed from the portion 5, the lid E can be easily opened without the need to bend the entire lid while bending it as in the conventional case. Further, since the pair of slits 20, 20 are formed symmetrically in the lid main body 1, there is an advantage that the lid E can be opened from any of the two directions. Further, since the bridge portion 22 is torn off when the lid E is opened, the virgin effect of the lid can be obtained, that is, the unauthorized use of the lid can be prevented. In the third embodiment as well, as in the second embodiment, the hanging portion 2 of the lid E may be provided with the handle portion 13.

Further, as a temporary lid of a so-called refill container 27 which is detachably loaded into a main container 26 which is opened and closed by a main lid 25 as shown in FIG. 5, the lid C of the first to third embodiments, D and E may be used. Further, it may be used as a temporary lid of the refill container 30 in which the hanging wall 5a is formed on the outer peripheral portion of the flange portion 5 as shown in FIG. In this case, the protrusions 5b such as knurls formed on the outer peripheral portion of the hanging wall 5a are fitted to the protrusions 4 at the lower ends of the hanging walls 2 of the lids C, D, and E, so that the refill container 30 is covered with the lid C, Install D and E.

[0026]

[Effect of the device]

 As described above, according to the container lid of claim 1 of the present invention, since the slit is formed in a part of the outer peripheral portion of the lid main body along the outer periphery of the lid main body, the lid is bounded by the slit. A part of the main body is divided into an outer peripheral side and an inner peripheral side. Therefore, when the lid is opened, the force that causes the hanging wall to act upward acts on the outer peripheral side, and the force that acts on the outer peripheral side is not offset or is not offset by the force that presses the inner peripheral side downward. Therefore, the force to open the lid acts effectively, and the slit makes it easier to open the protrusion to the outside and easily removes it from the flange of the container. The lid can be easily opened without the need to roll it up.

Further, according to the lid of the container of claim 2, since the bridge portion which is torn off when the lid is opened is formed between the wall portions forming the slit, the virgin effect of the lid is obtained, that is, Unauthorized use of the lid can be prevented.

Furthermore, according to the lid of the container of claim 3, since the handle portion projecting from the hanging wall is formed on the hanging wall on the side where the slit is formed, the force for opening the lid is reduced. The outer peripheral side of the lid body acts reliably and in a well-balanced manner, so that the opening can be performed more easily.
