Description

[Detailed Description of the Invention] The present invention relates to a paper cylinder with a handle, particularly to a paper cylinder suitable for use in combination containers.

A paper tube, a tube made by winding a long thin paperboard, can be used as a container by cutting it into a certain length and attaching a bottom and a lid, as well as a core material (winding core or bobbin) such as film or thread. . However, conventional paper tubes (including tubes, the same hereinafter) simply had a closed cross section, so when used as containers, the container body itself had to be opened each time when carrying or dispensing the contents. You have to grasp it and do it.
This makes the container inconvenient to use, as it can be accidentally dropped and the contents spill out, or the container can be compressed excessively and the contents can squirt out from the opening.This limits the thickness of the container, making it unnecessary. There was a problem in that it became so long that it became difficult to store it in a storage facility.

In addition, some core materials are quite thick and long, and handling them can be troublesome when transporting them. There were problems such as creating streaks. Furthermore, even when the container is made by combining it with a container body made of other materials, such as plastic, there is no merit in increasing the degree of freedom in printing, and the utility value is poor.

The present invention was devised in order to solve the above-mentioned problems, and its purpose is to improve the lightness of paper cylinders made by winding long and thin paperboard in layers around a mandrel by using a multilayer structure. To provide a paper tube which is inexpensive and can form a durable and easy-to-grip handle with one-touch operation when needed, while making use of excellent strength.

In order to achieve the above object, the present invention provides a paper cylinder made by winding elongated paperboard in layers around a mandrel, in which the body of the paper cylinder is normally flush with the paper cylinder body, and when necessary, the The handle piece is formed by punching out a protruding handle piece, and the handle piece includes a vertically elongated band-shaped grip part integrally connected to the paper tube main body, and a raised part for forming a space surrounding both end areas of the band-shaped grip part, Both ends of the band-shaped grip part and the base end of the raised part are connected to the main body of the paper tube as a line or a score line, and the remainder is cut by a drawing line. It has a configuration in which a notch is missing.

The present invention will be explained below based on examples.

Figures 1 and 2 show the main body of the paper tube according to the present invention, which is hollow with a circular or square cross section and is made by winding and laminating strips of paperboard, plastic film, metal foil, etc. as an inner layer, middle layer, and surface layer. Consists of structure. As for the winding method, a spiral method is preferable from the viewpoint of strength, but a flat winding method is not prohibited.
If water resistance is required, such as in containers for alcoholic beverages or drinking water, for example, as shown in Figure 1a, aluminum foil or plastic film can be used for the inner layer a and surface layer c, and water-resistant paperboard can be used for the middle layer b. It can withstand spraying and immersion in cold water well.

Reference numeral 2 denotes a handle piece, which is punched and formed in the body of the paper cylinder body 1 so that it is normally flush with the body surface and projects outward from the body when necessary.

In the embodiment shown in FIG. 1, the handle piece 2 consists of an intermediate band-shaped grip portion 20 and space-forming raised portions 21, 21 surrounding the end areas of the band-shaped grip portion 20. Both ends 22, 22 of the band-shaped grip part 20 are configured as lines or crevices so that they can be easily bent, and the width direction edges of both ends 22, 22 are separated from the paper cylinder main body 1 by punch lines 23, 23. .

The raised portions 21, 21 have the opposite ends 22, 21, respectively.
Base ends 24, 24 extending left and right from the drawn lines 23, 23 at a position slightly rearward from 22, and those base ends 2
The base ends 24 and 24 are integrally connected to the paper cylinder main body 1 by streaks or perforated lines. Band-shaped grip part 20
Cutouts 26, 26 for lifting the grip are formed in the drawn line portion corresponding to the center of the handle, as necessary. Small holes 27 are formed at the corners of the ends 24, 24.

Next, the usage situation and operation of the present invention will be explained.

The paper tube according to the present invention is made by punching out the handle piece 2 after manufacturing the paper tube body 1, and is fitted into the container body 3 as shown in FIG. It is used by fitting it onto other items.

When obtaining a handle, the belt-shaped grip portion 20
All you have to do is insert your fingertip or the like into the notch 26 opened on the side of the paper cylinder and lift the band-shaped grip part 20 in the direction away from the paper cylinder main body 1. As shown in FIG. , 21 protrude diagonally outward using the proximal ends 24, 24, which are made of stripes or folded lines, as fulcrums, and the band-shaped grip portion 20 is curved and separated from the paper tube main body 1 by the protrusion of these raised portions. Therefore, a larger grip space can be created compared to when the band-shaped grip portion 20 simply stands up. At this time, since the diagonally protruding protrusions 21, 21 provide vertical support for the gripping hand, a stable gripping state can be obtained without the fingers slipping.

In the usage example shown in FIG. 3, the container main body 3 is made of a bottle-shaped body made of plastic or the like and has an outlet 4, and the paper cylinder main body 1 is firmly fitted into the body of the container main body 3, and can be inserted as needed. Bonded using hot melt, heat seal, high frequency, ultrasonic, etc. A protrusion 41 formed by curling or the like is formed on the lower edge of the paper tube body 1.
is provided to prevent moisture from entering from the end face.

In the case of such a combination container, since the container body 3 is protected by the paper cylinder body 1, the wall thickness of the container body 3 can be made thinner, and since printing can be done freely, the container body can be made beautiful. Even if the bottom of the paper tube body 1 is spherical, the paper tube body 1 is cylindrical, which stabilizes the arrangement posture, and the handle piece is not attached separately but is flush with the body of the paper tube body 1, so the container In the process of filling the main body 3 with the contents, there is no irregular movement or stoppage caused by containers catching on each other, and smooth automatic filling can be performed. When necessary, the handle piece 2 protrudes outward from the paper cylinder main body 1 with one touch as described above, forming a strong handle, so that the tilting operation for carrying or taking out the contents can be easily performed.

According to the present invention explained above, in a paper cylinder made by winding elongated paperboard in layers around a mandrel, the body of the paper cylinder main body 1 is normally flush with the paper cylinder main body 1, and when necessary, the outer The handle piece 2 is formed by punching out a handle piece 2 that protrudes from the paper tube body 1, and the handle piece 2 is used to form a vertically elongated band-shaped grip portion 20 that is integrally connected to the paper tube body 1, and a space that surrounds both end areas of the band-shaped grip portion 20. Both ends of the band-shaped grip portion 20 and base ends 24, 24 of the raised portions 21, 21 are respectively connected to the paper cylinder main body 1 as streaks or score lines, and the remainder are drawn lines 23, 25. Because the paper tube is cut by the paper tube, it takes advantage of its light weight and good strength due to its multi-layered structure.In addition, it is easy to grip when needed, and the handle is of a type that does not apply shearing force, making it inexpensive without causing material loss. You can get the effects that you can create.

In particular, the handle piece 2 remains in the form of a band, with its thickness direction facing the paper tube body, making it easy to hold. The undulating parts 21, 21 protrude outward from the paper cylinder body 1, so a sufficiently large grip space can be formed, and the large undulating parts 21, 21 function as supports, improving grip stability. In addition to this, the connection strength with the paper tube main body 1 is also excellent, and it can be made durable.

Furthermore, since there is a notch 26 on the side of the band-shaped grip 20, the above-mentioned handle can be formed extremely easily by inserting a finger into the notch 26 and separating the band-shaped grip 20 from the paper tube body with a one-touch operation, making it easy to use. You can get excellent effects such as:
