Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an opening / closing mechanism for a cylindrical container, and more particularly to an opening / closing mechanism for a cylindrical container that can also be used as a mailer.
[0002]
[Prior art]
A conventional cylindrical container opening and closing mechanism firstly has a pair of bottomed cylindrical bodies having different heights that are open on one side, with the higher ones facing inward, and the opening surfaces of each other face each other. Fitted so as to be separable, and the outer bottomed cylindrical body is used as a lid so that the lid can be inserted and removed. Second, a so-called pull-top opening is provided on one side of the bottomed cylindrical container with the two sides closed. A configuration provided with a mechanism is common.
[0003]
[Problems to be solved by the invention]
According to this conventional example, in the first configuration, the lid can be easily opened and closed, and can be repeatedly opened and closed. However, since the lid can be easily opened and closed, It must be firmly bonded so as not to separate, making it difficult to open it, and sometimes the cylindrical container itself could not be opened without destroying it. Therefore, when used as this mailer, the opening operation is difficult and complicated, and when the cylindrical container is destroyed, it cannot be reused and must be discarded as garbage. Therefore, there is a disadvantage that it is contrary to resource saving.
[0004]
Further, in the conventional second configuration, once opened, the opening surface cannot be closed again, so that it cannot be reused as a storage container, and is discarded as garbage as in the first configuration. There is an inconvenience that it is against resource saving. An object of the present invention is to provide a cylindrical container opening / closing mechanism that eliminates the disadvantages of the conventional example.
[0005]
[Means for Solving the Problems]
In order to achieve this object, the cylindrical container opening and closing mechanism of the present invention is configured by fitting a pair of bottomed cylinders having one open face to each other so that the respective open faces face each other, and an inner bottomed cylinder is fitted. A cylindrical container comprising a body as a container, a bottom surface as a bottom surface, an outer bottomed cylindrical body as a lid body and a bottom surface as an opening / closing lid, and adhering circumferential surfaces that are in contact with each other. The peripheral edge of the container is rotatably held by the upper end of the peripheral surface of the container and the bent edge formed at the upper end of the peripheral surface of the lid, and a score line is formed from the peripheral edge of the opening / closing lid toward the center. The peripheral edge adjacent to the cut line of the open / close lid to form the open / close lid and to release the open / close lid from the lid body by rotating the open / close lid and sequentially running the peripheral edge on the bent edge of the lid body. Perforation for opening to expose the part to be picked up, the peripheral surface of the lid Those provided obliquely below from the edge.
[0006]
In the above configuration, if the container is provided with a notch at a position corresponding to the opening perforation formed obliquely downward from the upper end of the peripheral surface of the lid, the operation of picking the exposed peripheral edge of the opening / closing lid is more It is easy and suitable. In addition, even if the notch is formed larger than the opening perforation, it does not hinder the support of the opening / closing lid, so that the positioning of the lid with respect to the container is easy.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. Here, FIG. 1 is a perspective view of a cylindrical container, FIG. 2 is also a plan view, FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, and FIG.
[0008]
As shown in FIGS. 1 to 3, the cylindrical container 1 includes a pair of bottomed cylindrical bodies that are both made of paper and open on one side, with their open surfaces facing each other, and an inner bottomed The cylindrical body is used as the housing body 2 and the bottom surface thereof is used as the lower surface 4. The outer bottomed cylindrical body is used as the lid body 3 and the bottom surface thereof is used as the opening and closing lid 5.
[0009]
As can be understood from FIG. 3, the opening / closing lid 5 is sandwiched from above and below by the upper edge of the peripheral surface 2 a of the container 2 and the bent edge 3 b formed at the upper end of the peripheral surface 3 a of the lid 3. Therefore, it is supported rotatably. And the slit 6 which is a cut line is formed toward the center from the periphery of the said opening-and-closing lid 5.
[0010]
As can be understood from FIGS. 1 and 2, the lid 3 is provided with an opening perforation 7 obliquely downward from the upper end including the bent edge 3 b of the peripheral surface 3 a. The opening perforation 7 is for breaking the perforation 7 and exposing the peripheral edge adjacent to the slit 6 of the opening / closing lid 5. On the other hand, as can be understood from FIG. 3, a rectangular cutout portion 8 is provided at the upper end portion of the peripheral surface 2 a corresponding to the opening perforation 7 of the container 2 so that the exposed peripheral portion can be easily picked. Provided. The notch 8 has a sufficiently long circumferential length as compared with the opening perforation 7. Therefore, the positioning of the lid 3 with respect to the container 2 is easy without requiring high accuracy.
[0011]
Although not shown in the figure, a storage such as a circular leaflet or leaflet having a diameter substantially the same as the inner diameter of the storage body 2 is stored in the storage body 2. The storage of the storage is performed before the lid 3 is fitted to the storage 2 and the peripheral surfaces 2a and 3a are bonded to each other. When the cylindrical container 1 is used as a mailing body, either the opening / closing lid 5 or the exposed surface of the lower surface 4 is used as an address display surface, where an address label indicating the address is attached or the address is directly entered. To do.
[0012]
Then, the opening operation | movement of the cylindrical container 1 is demonstrated based on FIG. First, the opening perforation 7 is broken, and this portion is rolled up outward in a triangular shape to expose the peripheral edge adjacent to the slit 6 of the opening / closing lid 5. At this time, if the slit 6 does not correspond to the opening perforation 7 portion, the opening / closing lid 5 is rotated to a corresponding position.
[0013]
Next, the peripheral edge adjacent to the exposed slit 6 of the opening / closing lid 5 is picked up, and a notch 8 provided at the upper end of the peripheral surface 2a of the container 2 is formed at the broken portion of the opening perforation 7. Since it is in the corresponding position, it can be picked up easily. At this time, the left or right side of the slit 6 is determined by the rotation direction of the opening / closing lid 5, and here, as shown in FIG. 4, the fracture extending obliquely lower right from the bent edge 3 b of the lid 3. It is assumed that the right side of the slit 6 is picked up so as to rotate the opening / closing lid 5 toward the opening perforation 7.
[0014]
In this case, the opening / closing lid 5 is rotated in the direction of the arrow in FIG. 4 and picked up on the back side of the peripheral edge on the bent edge 3b of the lid 3 and continues to rotate in the same direction. When the opening / closing lid 5 is rotated almost once, the opening / closing lid 5 is completely detached from the lid body 3. It will be in the open state which the upper surface opened. And the storage thing stored in the container 2 can be taken out from this upper surface opening part.
[0015]
Further, in order to put the cylindrical container 1 into the sealed state again, the peripheral portion adjacent to the slit 6 picked up by the opening / closing lid 5 is opposite to the periphery of the container 2 corresponding to the opening perforation 7. It is placed on the upper end of the surface 2a, the surface side of the peripheral portion is made to correspond to the bottom of the bent edge 3b of the lid 3, and the rotation of the opening / closing lid 5 is continued in the direction opposite to the arrow in FIG. When the opening / closing lid 5 is rotated approximately once by holding the bent portion 3b under the bent edge 3b in order, the bent edge 3b is sandwiched between the upper end of the peripheral surface 2a and the opening / closing lid 5 is rotated approximately once. The curved edge 3b and the upper end of the peripheral surface 2a are in a sealed state in which the peripheral edge is sandwiched from above and below.
[0016]
Note that the present invention is not limited to the above-described embodiment. For example, it is preferable that at least a part of one of the opening / closing lid 5 or the lower surface 4 is configured to be seen through so that the stored item can be visually recognized. . Further, the cut line provided in the opening / closing lid 5 may be constituted by a perforation in addition to the slit 6. Furthermore, the notch 8 provided in the container 2 is not necessarily provided. Further, the opening perforation 7 may be formed in a V shape in addition to being formed to extend obliquely downward from the upper end including the bent edge 3b of the lid 3.
[0017]
【The invention's effect】
As described above, according to the opening and closing mechanism of the cylindrical container according to claim 1 of the present invention, the opening and closing of the opening and closing lid can be easily repeated, and the cylindrical container after opening can be reused. In addition, there is no risk of inadvertent opening during handling in the closed state, and it cannot be opened unless the opening perforation is broken, so whether or not it has already been opened even in the closed state In addition, it is easy to take out stored items because a wide opening is formed at the time of opening, and it is ideal for storing circular items. In addition, it is also suitable for use as a mailer. There is an effect.
[0018]
Moreover, according to the opening / closing mechanism of the cylindrical container according to claim 2 of the present invention, in addition to the above effect, by providing the notch, the peripheral edge adjacent to the cut line of the opening / closing lid is picked up. And the opening / closing operation can be performed more smoothly.
