Abstract

(57) Abstract: An object of the present invention is to provide a packaging container that can be easily closed while containing articles and that can be transported safely. SOLUTION: A pair of closing piece parts 5 are formed on the outer peripheral front and back surfaces of a cylindrical body 1 having an open end surface formed of cardboard or the like, and a pair of closing piece parts 5 are formed so as to be in contact with an opening edge 3. The portions 5 and 5 are recessed inward so that the opening 2 can be closed by keeping this state.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a packaging container for accommodating and transporting rolled calendars and posters.

[0002]

[Prior art]

 Although such a tubular packaging container has been known and used in the past, the conventional packaging container simply consists of a tubular body and, for example, a wrapping paper is placed on the surface of the tubular body in a state of containing the wound article inside. Was wound and covered, and the opening end face was closed by folding the end of the wrapping paper protruding from the opening end edge of the tubular body into the tubular body. Alternatively, a separately formed lid is attached to the opening end face to close it.

[0003]

[Problems to be solved by the device]

 However, in the case of the former, not only is the work extremely troublesome, such as winding the wrapping paper and folding the end of the wrapping paper into the cylinder, and the articles stored during transfer are displaced within the cylinder due to vibration. , It may break the edge of the wrapping paper and jump out. Also, in the latter case, although it is sturdy in that respect, the cost is high because the lid is made separately from the tubular body, and if the contained items are heavy, the lid must be sealed by taping or the like. There was a problem that the lid came off and the article jumped out of the cylinder. Therefore, the present invention has been made to solve the above-mentioned problems, and provides a packaging container in which articles can be easily packaged in a tubular body, and in which the articles do not pop out of the tubular body during transfer. Is intended.

[0004]

[Means for Solving the Problems]

 In order to achieve such an object, the packaging container according to the present invention is formed of a cardboard or other thick paper to form a hollow cylindrical body having an open end surface, and the front and back surfaces of the outer periphery of the cylindrical body are respectively curved in an arc shape and both ends thereof are Is provided with a folding curve extending to the opening edge, and a pair of closing pieces surrounded by the folding curve are formed to face each other so as to be in contact with the opening edge. After accommodating an article such as a rolled calendar in the cylinder, each closing piece is depressed along the fold line to the inside of the cylinder so that the state can be maintained. As a result, both of the opposing closing pieces are recessed inward toward each other to firmly close the opening edge of the tubular body and prevent accidental opening. In addition, if necessary, an adhesive tape may be applied between both of the closing pieces that are recessed inward to make the closed state more complete.

[0005]

[Embodiment of the invention]

 An embodiment of a packaging container according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the packaging container. In the figure, reference numeral 1 denotes a hollow cylinder formed of cardboard or other cardboard having a desired diameter and length so that a calendar, poster or the like can be stored in a rolled state. Both end faces of the cylindrical body 1 have openings 2 as shown in FIG.

Further, on the outer circumference of both ends of the cylindrical body 1, there are provided folding curves 4 on the front and back surfaces, which are curved in an arc shape and whose both ends 4 a, 4 a reach the opening edge 3. As a result, a pair of closing piece portions 5 and 5 surrounded by the folding curve 4 are formed so as to be in contact with the opening edge 3 and face each other. The size of the pair of blocking pieces 5, 5 is selected to cover the entire surface of the opening 2 when recessed inward, and in the recessed state, elasticity due to the material of cardboard or other cardboard is imparted. It will not naturally return to its original state.

The packaging container according to the present invention having the above-described structure is provided with the articles G such as calendars and posters wound in the cylindrical body 1 as shown in FIG. By pressing the central portions of 5, 5 to the inside of the tubular body 1 with the fingertips, it is possible to make indentations along the folding lines 4, 4 respectively. As a result, the closing pieces 5 and 5 are inwardly inwardly closed to firmly close the opening 2. In this state, the closing pieces 5 and 5 do not easily open due to the stiffness of the cardboard or other thick paper, and the articles G accommodated by the vibrations during the transfer cause the closing pieces 5 and 5 to move. Do not accidentally jump out of the opening 2 by pushing. In this way, the closed state of the opening 2 is maintained, but especially when the housed article G is heavy, it is possible to stick a tape or the like between the ends of the closing pieces 5 and 5 to seal them. Safer.

Further, when taking out the article G from the inside of the tubular body 1, it can be easily opened by pushing open the closing pieces 5 and 5, and the article G can be taken out easily. The folding curves 4 and 4 are not limited to the illustrated circular arc shapes and may be substantially V-shaped.

[0009]

[Effect of the invention]

 As described above, in the packaging container according to the present invention, the opening of the cylinder can be closed by a one-touch operation in which the closing pieces provided in contact with the opening edge of the cylinder are pressed inward with each other. It is simple, and the closed state is stable, and the articles can be transported safely without the problem that the articles to be contained jump out from the opening. In addition, opening can be done by a one-touch operation that causes a blocking piece, which has the effect of being reusable and economical.
