DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used by a manufacturer of paper containers and the like, and processes a tubular body obtained by cutting a long paper tube into a fixed size to produce a paper tube container and a lid. The present invention also relates to a paper tube container which can smoothly provide a container with different capacities, and which can be provided at a low cost and which can be provided at low cost.

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Laid-Open Publication No. Sho 61-202234, a capsule tube lid which can be fitted on both sides of a cylindrical body is attached as a writing tube for holding a tip in the middle.
A structure in which an inner lid made of a resilient material having a radial cutout can be fitted into the opening of the main body, or as disclosed in Japanese Utility Model Laid-Open Publication No. 3-23012, a simple tubular paper container. In a simple container that is formed in a substantially cylindrical shape with the main material as a main material, a lid portion is attached to the upper opening and the container is closed, and the trunk portion is protruded toward the center near the opening edge. There is proposed a configuration in which a groove extending in the circumferential direction is formed facing the outer surface, and the lid is locked or sealed using the groove. In addition, JP-A-63-33244
And a method of manufacturing the same. Further, paper containers disclosed in Japanese Utility Model Laid-Open No. 63-186612 have been proposed.

However, the diameter of the opening portion of the tubular main body (the portion to which the capsule tube lid is fitted) is smaller than the diameter of the middle portion of the main body of the writing brush holding the ear tip in the middle. In the case, since the inside is stepped, it is not possible to efficiently mass-produce containers such as tea leaves,
Forming a bottomed container is difficult. In addition, those disclosed in other publications also have a problem that a long paper tube cannot be cut into a predetermined size to form a container continuously and easily.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide a long paper tube having the same diameter from one end to the other end. An edge winding part is formed on the container cylinder and the lid cylinder obtained by cutting to a certain size, and the bottom plate and the top plate are respectively fastened to each other. A punched-out ridge-forming portion is formed by the ridged rotating roll and the ridge-forming roll, so that there is no problem in taking in and out of tea leaves and the like accommodated from the opening to the bottom in the container with the same diameter. Simple of container,
Another object of the present invention is to provide a paper tube container that can be easily mass-produced.

[0005] Means of the paper tube container according to the present invention for achieving the above object is to provide a container tube obtained by cutting a long paper tube having the same diameter from one end to the other end into a predetermined size. A paper tube container in which a bottom plate is locked to the edge winding portion, and a long paper tube slightly larger in diameter than the diameter of the paper tube container are cut into fixed dimensions. A wrapping portion is formed at one of the openings, a top plate is fixed to the wrapping portion, and a lid made of a paper tube is detachably fitted into the paper tube container. on the opening side of the ridge with a rotating roll, formed to protrude outward by a ridge forming roll, and stop the lower end of the cover
And a protruding projection-like stringing portion.

[0006]

When using the paper tube container of the present invention, the paper tube lid fitted to the opening portion of the paper tube container is removed and the contents such as tea leaves are stored in the paper tube container. After being stored in a predetermined manner, a lid is fitted into the opening of the paper tube container. At this time, the lower end of the lid stops at the protruding portion formed on the peripheral wall of the paper tube container. Also, when taking out the stored contents, the lid is removed and taken out from the opening of the container. At this time, the paper tube container has a long paper tube having the same diameter from one end to the other end and having a constant size. Since it is formed by a container cylinder obtained by cutting into
The whole amount can be taken out smoothly and easily.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a paper tube container according to the present invention will be described with reference to the drawings. FIG. 1 shows a longitudinal section of a paper tube container in which a protruding strip is formed on the peripheral wall of a container. FIG. 1 is a front view showing a paper tube container according to this embodiment. The paper tube container 1, a paper tube lid 2 removably fitted into the opening of the paper tube container 1, and a paper tube container 1 are shown. The paper tube container 1 is formed by cutting a long paper tube having a predetermined diameter into a predetermined size. The lower end is curled and the bottom plate 5 is locked to the curled portion 4 to form a bottomed container.

Next, the paper tube cover 2 is formed by cutting a long paper tube having a diameter slightly larger than the diameter of the paper tube container 1 into a predetermined size to form an edge winding portion 6 at one opening. The top plate 7 is fixed to the rim winding portion 6 to form a fitting lid, and the fitting lid is removably fitted to the opening side of the paper tube container 1.

In addition, the ridge cord portion 3 formed on the peripheral wall of the opening portion of the paper tube container 1 according to the present invention has a structure as shown in FIGS. And a pair of ridge forming rolls 10 and 10 having a frustoconical shape on the outside and obliquely opposed to each other, respectively. Roll 9, 10, 10
Is rotated to form the endless protruding strip-out part 3.

As described above, the paper tube container according to this embodiment is a paper tube cover 2 fitted into the opening of the paper tube container 1 in use.
The container is removed and the container such as food is stored in the container 1 as it is. After the container is stored in a predetermined manner, the lid 2 is fitted into the opening of the paper tube container 1. At this time, the lower end of the lid 2 stops on the protruding cord pulling-out part 3 formed on the peripheral wall of the paper tube container 1, and the lid 2 is settled well.

[0011]

The means for a paper tube container according to the present invention for achieving the above object is a container tube obtained by cutting a long paper tube having the same diameter from one end to the other end into a predetermined size. A paper tube container having a rim portion formed at the lower end thereof and a bottom plate fixed to the rim portion, and a long paper tube slightly larger in diameter than the diameter of the paper tube container are cut into a predetermined size. And forming a rim portion in one of the openings, a top plate fixed to the rim portion, and a lid made of a paper tube which is removably fitted to the paper tube container. A rotating roll with a ridge and a ridge forming roll are formed to protrude outward on the opening side of the container, and the lower end of the lid is stopped.
Since it is composed of a protruding projecting stringing part, there is no step as in the conventional case even if stringing is formed. In addition, since the container tube is formed by cutting a long paper tube into a certain size, it has an excellent effect of mass productivity, and has a unique effect that the container can be formed continuously, easily, easily and inexpensively.
