Description

  The present invention relates to a writing instrument such as a pencil in which information on quality control is mainly recorded on a shaft surface.

  Conventionally, a pencil is manufactured by a process as disclosed in Patent Document 1 below.

JP 2007-62061 A

  In many cases, quality control information such as a lot number is stamped on the shaft surface of a writing instrument such as a pencil. A pencil is usually hexagonal in cross section (or circular in cross section) and has six side surfaces (or one cylindrical side surface). Therefore, in order to engrave on a specific surface on the production line, it is necessary to set the position of the engraving surface, and the control becomes complicated, so it is accidentally engraved on the side facing the engraving device. Currently.

  On the other hand, there is a case where a picture is displayed on the surface of the pencil mainly due to a request for design. Usually, a picture is displayed by sticking a transfer film on which a picture (for example, a character such as a cartoon or an animation) is printed on the surface of a pencil. In this case, since the product value is reduced when an important part of the design (for example, a character's face) is stamped, the lot number or the like is not stamped. However, even in such a case, it is desirable to record some quality control information from the viewpoint of traceability.

  Therefore, the present invention provides quality control information such as a lot number so as not to impair the design even when a transfer layer such as a transfer film is formed on the surface of a writing instrument such as a pencil. It is an object to be able to record.

  In view of the above problems, the present invention is a writing instrument 10 having a transfer layer 26 on the surface of the shaft 20, and the information recording portion 27 is formed on the surface of the transfer layer 26 by a tear 28 that is difficult to see. It is characterized by.

  The “transfer layer 26” refers to a layer formed by being attached to the surface of the shaft 20 using the transfer film 30, for example.

  This "difficult to see 28" is applied to the transfer layer 26 by applying a force such as a physical stamp 35 to the transfer film 30 before the application (or directly to the transfer layer 26 generated after the application). It is formed by generating a tear 28 that accompanies a general deformation. Here, “rupture 28” is “difficult to see” means that, although it is not visible at all or almost visually, for example, when lightly rubbed with a pencil core, characters and the like appear to be raised and uneven to a degree that can be visualized. It means that the surface is torn.

  Here, the tear 28 may be formed by an inscription 35 formed from the surface side of the transfer layer 26. Further, the tear 28 may be formed by an inscription 35 applied from the back side of the transfer layer 26. Such a configuration can be realized, for example, by marking in advance 35 from the front surface or the back surface of the transfer film 30.

  In the present invention, the transfer layer 26 affixed to the surface of the shaft 20 is preliminarily cut 28 by the marking 35, so that information such as a lot number can be recorded at any place that does not hinder the design. Can do.

  The writing instrument 10 according to the present invention may be of any type, and may have, for example, the transfer layer 26 as described above on the surface of the ballpoint pen 12. However, the present invention is most useful when the writing instrument 10 is the pencil 11. That is, when the shaft 20 is the wooden shaft 21 of the pencil 11, it is often performed to provide a transfer layer 26 on the surface, but the transfer layer 26 is physically broken as described above. By applying the marking 35 that generates 28, it is possible to record information such as the lot number without performing the stamping later.

  Since the present invention is configured as described above, even when a transfer layer such as a transfer film is formed on the surface of a writing instrument such as a pencil, the design is not impaired. Quality control information such as a lot number can be stamped and recorded at an arbitrary location. In addition to managing lots, for example, by recording something like a hidden character only on the surface of a genuine product by such an engraving, it is possible to use it for authenticity determination of a counterfeit product.

The pencil as a writing instrument which concerns on the 1st Embodiment of this invention is shown with (A) perspective view, (B) side view, and (C) side sectional drawing. A part of the information recording part is schematically shown in a sectional view. Two examples of the transfer film corresponding to FIG. 2 are schematically shown in cross-sectional views. 1. The pencil manufacturing process of FIG. 1, wherein (A) a transfer film before stamping, (B) a transfer film after stamping, (C) before pasting the transfer film on a wooden shaft and (D) a transfer film Each after sticking to a wooden shaft is typically shown in a perspective view. The ball-point pen as a writing instrument which concerns on the 2nd Embodiment of this invention is shown with a perspective view.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(1) 1st Embodiment The writing instrument 10 which concerns on 1st Embodiment is the pencil 11 as shown in FIG. This pencil 11 accommodates a core 25 at the center of a wooden shaft 21 (see FIG. 1A) as a shaft 20 having a hexagonal cross section, as in a normal pencil (FIGS. 1A and 1C). )reference).

  An information recording unit 27 indicating information such as a lot number is provided on a part of the surface of the wooden shaft 21 (see FIGS. 1A and 1B). The information in the information recording unit 27 is difficult to view because it is recorded with fine tears 28 that are not visible unless special measures are taken. Then, for example, a character (or a figure, a pattern, etc.) emerges and is visualized by applying a special treatment such as rubbing lightly with a pencil lead from above the tear 28. In FIG. 1, the information recording unit 27 is displayed with visible characters for convenience.

  The information recording unit 27 shown in FIGS. 1A and 1B specifically has a structure as shown in FIG. A transfer layer 26 is formed on the surface of the wood shaft 21 as the shaft 20. The transfer layer 26 is in order of the adhesive layer 33, the printing layer 32, and the release layer 31 from the lower layer. The release layer 31 is a resin sheet formed of an acrylic resin for protecting the printing layer 32 while making the transfer property of the transfer layer 26 structured by facilitating peeling from the base film 34 (see FIG. 3). is there. The printed layer 32 has a design such as a pattern, an illustration, a color or the like applied from the back side of the release layer 31 with ink. The adhesive layer 33 is a thermoplastic acrylic resin layer. In the region to be the information recording unit 27, the transfer layer 26 has a tear 28 due to physical deformation. A method for generating the tear 28 will be described later.

  The transfer layer 26 is formed by sticking a transfer film 30 as shown in FIG. The transfer film 30 has a base film 34 attached to the upper layer of the release layer 31 described above. In other words, the peeling layer 31 is located below the base film 34, the printing layer 32 is located below it, and the adhesive layer 33 is located below it. The sticking of the transfer film 30 to the wooden shaft 21 will be described later.

  Then, as shown in FIG. 3A, by stamping from the surface side of the transfer film 30 (that is, the base film 34 side), a marking 35 having a recessed surface side is formed. The tear 28 occurs in the printing layer 32 and the adhesive layer 33. Alternatively, as shown in FIG. 3B, by stamping from the back surface side of the transfer film 30 (that is, the adhesive layer 33 side), an indentation 35 having a recessed back surface side is formed. The tear 28 occurs in the printing layer 32 and the release layer 31. By affixing any of these to the wooden shaft 21, an information recording portion 27 is formed by a tear 28 generated on the surface side as shown in FIG.

  An outline from the marking 35 of the transfer film 30 to the sticking to the wooden shaft 21 will be described with reference to FIG. FIG. 4A shows the transfer film 30 before the marking 35 is applied. The transfer film 30 has a predetermined design in the print layer 32 (not shown). Next, as shown in FIG. 4B, a marking 35 is given. From this state, the adhesive layer 33 is attached to the surface of the wooden shaft 21 by heating while peeling the surface base film 34 from the transfer film 30 in the order shown in FIGS. 4C and 4D. Then, the transfer layer 26 is formed by pasting. At the time of this pasting, the deformation (see FIGS. 3 (A) and 3 (B)) of the release layer 31, the printing layer 32 and the adhesive layer 33 associated with the marking 35 on the transfer film 30 before the pasting is eliminated and the flat state is restored. (See FIG. 2). However, the portion of the tear 28 accompanying the stamp 35 remains as it is, and it becomes the information recording unit 27 (see FIG. 2).

(2) Second Embodiment A writing instrument 10 according to a second embodiment is a ballpoint pen 12 as shown in FIG. By attaching the transfer film 30 as shown in FIG. 3 to the surface of the shaft cylinder 22 as the shaft 20 of the ballpoint pen 12, the same as in the first embodiment, at a predetermined location of the shaft cylinder 22 Thus, the information recording unit 27 is formed. The structures of the transfer film 30, the transfer layer 26, and the information recording unit 27 are the same as those in the first embodiment.

  The present invention can be used to record information such as a lot number on the surface of a writing instrument such as a pencil.
