Description

  The present invention relates to a ballpoint pen, and more particularly to a tube-type ballpoint pen having design properties.

  Conventionally, in addition to a ballpoint pen that has a simple bar shape and is used exclusively for office purposes, various designs that have been designed with various decorations have been put to practical use.

  Among these, as a product with a refined design, a core holding member that holds the core of a ballpoint pen is formed of a synthetic resin molded body in the shape of a fruit or vegetable (for example, Patent Document 1). However, in the case of a molded body made of synthetic resin, there is a problem that fine coloring is difficult to be applied.

Japanese Utility Model Publication No. 4-27669

  An object of this invention is to provide the tube-type ball-point pen which has the designability which can give a fine coloring.

  In order to achieve the above object, a tube-type ballpoint pen of the present invention has a ballpoint pen core, a synthetic resin core holding member for holding the ballpoint pen core, and a tip of the ballpoint pen core held by the core holding member. A tube member that covers the entire core holding member so as to protrude from the mouth portion, and a cap that is mounted on the mouth portion of the tube member so as to cover the tip of the core of the ballpoint pen protruding from the mouth portion of the tube member. It is characterized by.

  According to the tube-type ballpoint pen of the present invention, the entire core holding member is covered with the tube member so that the tip of the ballpoint pen held by the core holding member protrudes from the mouth portion. A tube-type ballpoint pen that can be colored, has design properties, and is suitable as a fancy goods or novelty goods can be provided.

One Example of the tube type ball-point pen of this invention is shown, (a) is an expanded view, (b) is a fragmentary sectional view. The core holding member is shown, (a1) to (a3) are three views of the core holding member in an open state, and (b1) to (b2) are two views of the core holding member in a closed state. It is a three-plane view showing the tube type ballpoint pen.

  Embodiments of a tube-type ballpoint pen according to the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the tube-type ballpoint pen of the present invention.
As shown in FIG. 1, this tube-type ballpoint pen includes a ballpoint pen core 1, a synthetic resin core holding member 2 that holds the ballpoint pen core 1, and a ballpoint pen core 1 held by the core holding member 2. The tube member 3 that covers the entire core holding member 2 so that the tip 11 of the tube protrudes from the mouth 31, and the tube member 3 that covers the tip 11 of the core 1 of the ballpoint pen that protrudes from the mouth 31 of the tube member 3. The cap 4 attached to the mouth portion 31 and the strap 5 attached to the cap 4 are provided.

  In this case, a conventionally known oil-based or water-based ballpoint pen core 1 can be used as the core 1 of the ballpoint pen.

As shown in FIG. 2, the core holding member 2 is formed of a synthetic resin molded product such as polyolefin resin, and in this embodiment, a mouth portion 21 from which the tip 11 of the ballpoint pen core 1 protrudes is formed on the tip side. The divided bodies 2a and 2b are connected to each other via a flexible connecting portion 22 on the base end side so as to be configured as an integral structure.
Further, the core holding member 2 is provided with a groove-shaped core holding portion 23 in order to hold the core 1 of the ballpoint pen.
By the way, in this embodiment, the diameter of the mouth portion 21 is formed smaller than the diameter of the core holding portion 23 so that the tip 11 of the core 1 of the ballpoint pen can be securely held by the mouth portion 21. In order to allow the core 1 to be exchanged, the diameter of the mouth portion 21 and the diameter of the core holding portion 23 can be formed to the same diameter.
The core holding member 2 is configured to hold the ballpoint pen core 1 by combining the divided bodies 2a and 2b so as to sandwich the ballpoint pen core 1. At this time, the integrity of the divided bodies 2a and 2b is improved. In order to hold the core 1 of the ballpoint pen more securely, a fitting portion composed of the fitting protrusions 24a and 25a and the fitting holes 24b and 25b is formed on the joining surfaces of the divided bodies 2a and 2b. I have to. In addition, since the core holding member 2 is constrained by covering the whole with the tube member 3, the fitting portion can be omitted as shown in FIG.

  The tube member 3 is made of a tube made of synthetic resin (including laminate) such as polyethylene resin used for paints and toothpastes. As shown in FIGS. 1 and 3, the tube member 3 is a ballpoint pen held by the core holding member 2. In a state where the entire core holding member 2 is covered so that the distal end 11 of the core 1 protrudes from the mouth portion 31, the base end side is sealed by sealing 32.

  The cap 4 is made of a synthetic resin molded product such as polyolefin resin, and is attached to the mouth portion 31 of the tube member 3 so as to cover the tip 11 of the core 1 of the ballpoint pen protruding from the mouth portion 31 of the tube member 3. Thus, the hook portion 41 for attaching the crab 51 of the strap 5 is formed on the surface.

  In this tube-type ballpoint pen, the entire core holding member 2 is covered with the tube member 3 so that the tip 11 of the core 1 of the ballpoint pen held by the core holding member 2 protrudes from the mouth portion 31. Like toothpaste, tube member 3 can be finely colored (decoration by thermal transfer, etc.), has a design, and is suitable for fancy goods and novelty goods such as paints and toothpaste novelty goods A ballpoint pen can be provided.

  As mentioned above, although the tube type ball-point pen of the present invention was explained based on the example, the present invention is not limited to the composition described in the above-mentioned example, and changes the composition suitably in the range which does not deviate from the meaning. Is something that can be done.

  Since the tube-type ballpoint pen of the present invention has a design property that enables fine coloring, it can be suitably used for fancy goods and novelty goods.
