Description

  The present invention relates to a cover member such as a notebook cover, a household account cover, a notebook cover, and a book cover provided with a pen holder portion that can hold a pen.

Conventionally, many cover members such as notebook covers are known. For example, the notebook cover protects the notebook surface and prevents the dirt on the pockets of the notebook. Many of them are designed to be equipped with (writing instruments) and various portable items.
As a notebook cover, there is known a card cover section that can store a cash card, a business card, etc., and a pen holder section. As the card storage section, for example, there are those in which sheets are stacked and an opening is provided so as to have an area slightly larger than the surface area of the card, and a card can be inserted by providing a notch in the base material Are known.

4A and 4B are views showing a notebook cover provided with a pen holder as an example of a conventional cover member, where FIG. 4A is a plan view and FIG. 4B is a schematic cross-sectional view.
In FIG. 4, on both sides of the base portion 1 made of a resin sheet, a support piece 2 that supports both sides of the notebook is laminated, and a card storage piece 4 that can hold a cash card, a business card, etc. is further laminated. Three edge portions of the portion 1, the support piece 2, and the card storage piece 4 are welded. Further, in the drawing, a pen holder portion 3 is provided at the right outer edge portion. The pen holder portion 3 is formed by forming a belt-shaped resin sheet into a ring shape and welding both ends of the resin sheet overlapped with the outer edge portion of the support piece 2. Can be inserted.

  However, in a cover member such as a conventional notebook cover as shown in FIG. 4, a pen is required in many cases where a notebook or the like is used. Therefore, when the notebook cover does not have the pen holder portion 3, the cover of the notebook is used. There is a problem that the pen is easily dropped when carrying it.

  On the other hand, in the case of a notebook cover provided with the pen holder part 3, when the support piece 2 is laminated on the base part 1 and the three edge portions of the support piece 2 are welded, the base part 1, the support piece 2, and the card storage part The three resin sheets with the piece 4 are welded. However, when the pen holder part 3 is further welded as in the example shown in FIG. Since it is laminated | stacked on the base | substrate part 1, the support piece 2, and the card storage part piece 4, in this part, five sheets of resin sheets will be piled up. That is, in the case of the shape of the pen holder portion 3 in FIG. 4, the thickness increases rapidly from three resin sheets to five resin sheets as shown in the schematic cross-sectional view of FIG.

  In the welding step, it becomes very difficult to set the processing conditions for welding at the intersection 5 between the card storage piece 4 in FIG. 4B and both end edges of the pen holder 3. That is, five resin sheets are reliably welded, and further, the portion at the intersection point 5 is a portion where tensile stress is frequently applied, so that it is necessary to ensure sufficient strength.

  For example, when welding is performed on the basis of the case where three pieces of the base portion 1, the support piece 2, and the card storage piece 4 are welded, the weld strength is increased at the portion where the five resin sheets of the pen holder portion 3 are overlapped. There is a problem that the pen holder unit 3 may be removed from the notebook cover during use of the notebook cover.

  On the other hand, when welding is performed based on the case where five resin sheets are welded so that the pen holder portion 3 can be sufficiently welded, the portion without the pen holder portion 3, that is, the base portion 1 and the support piece 2, the card storage portion. In the part where three resin sheets with the piece 4 overlap, there is a problem that the processing effect acts excessively and the support piece 2 and the base part 1 may be melted excessively. For this reason, when the pen holder part 3 is provided on the notebook cover by welding, there is a problem that it is very difficult to set processing conditions at the time of welding.

  Moreover, in the pen holder part provided in the conventional notebook cover as shown in FIG. 4, since the outer edge part of the base part 1 and the pen holder part 3 are welded at a right angle, tensile stress such as torsion is likely to be concentrated. Therefore, it was necessary to increase the thickness of the resin sheet or to use a strong sheet material.

  The present invention has been made in view of the above, and it is easy to set processing conditions at the time of manufacture, is low in cost and high in strength, is difficult to peel off, and has a pen holder portion that does not get in the way when the pen is not in use. It is to provide a member.

  The present invention achieves the above-mentioned problems, and the cover member according to claim 1 is a base part made of a resin sheet, and an end part is formed by folding a belt-like resin sheet on the outer edge part of the base part. A pen holder portion fixed to the outer edge portion is provided, and each apex of the end portion of the pen holder portion that is folded and fixed is not overlapped.

  The invention of claim 2 is characterized in that, in the cover member according to claim 1, the pen holder portion has a tapered end portion to which the belt-like resin sheet is fixed.

  In the invention of claim 1, since the cover member of the present invention does not overlap the apex portion to which the pen holder portion is fixed, only the overlapped apex portion is welded as in the conventional pen holder portion as shown in FIG. There is an advantage that the thickness does not suddenly increase and it becomes very difficult to set the processing conditions at the time of welding, and the maintenance of quality is very easy.

  Furthermore, since the pen holder part is bent flat when the pen holder part is not used, the pen holder part does not get in the way.

  Further, in the invention of claim 2, since the end portion to which the pen holder portion is fixed is tapered, even when the pen holder portion is pulled, the end portion is fixed rather than the case where the end portion is fixed at right angles to the outer edge portion. There is an advantage that it is difficult to peel off because the tensile stress is difficult to concentrate on the portion. Therefore, compared to the case where the base part and pen holder part are welded at right angles, the thickness of the resin sheet can be reduced, and it is not necessary to use a strong sheet material, thus reducing the manufacturing cost. Can do.

It is a top view which shows an example of embodiment of the cover member of this invention. It is an expanded view before welding of the pen holder part of the cover member of this invention. It is an enlarged view of the manufacturing process of the pen holder part of the cover member of this invention. (A) is an enlarged view of the pen holder part before welding, (b) is a schematic sectional view of the pen holder part, and (c) shows an enlarged view of the pen holder part after welding. It is a figure which shows an example of the conventional notebook cover, (a) shows a top view, (b) shows the cross-sectional schematic diagram of a pen holder part.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The cover member of the present invention can be applied to a notebook cover, a household account cover, a notebook cover, a book cover, etc. In this embodiment, an embodiment of a cover member when applied to a notebook cover will be described.
FIG. 1 is a plan view showing an example of an embodiment of a cover member (notebook cover) according to the present invention.
In the cover member 10 of FIG. 1, the base portion 11 and the support pieces 12 a and 12 b are formed by forming a resin sheet that is transparent, translucent, or colored black or blue into a rectangular shape. Examples of these types of resins include PVC (polyvinyl chloride), PE (polyethylene), EVA (ethylene vinyl acetate), and PP (polypropylene).
The support pieces 12 a and 12 b are respectively provided on the left and right sides of the inner surface of the base body 11. The support pieces 12a and 12b are opened at only one side on the back side of the base portion 11, and the other three outer edges are fixed to the outer edge of the base portion 11 by welding with a high-frequency welder or the like.

  Moreover, the pen holder part 13 is welded to a predetermined position of the outer edge part of the base part 11 and the support piece 12b. Usually, since there are many right hand strokes, a pen holder 13 is provided on the outer edge of the top right of the plan view as shown in FIG. 1 so that the pen can be easily taken out when the notebook is opened. However, the present invention is not limited to this, and the welding position and the crease side may face outward.

  Further, a slit 15 is formed in the support piece 12 a on the left side of the base body portion 11. The slit 15 is a portion for storing a sheet-like body in the cover member 10, and is composed of a notch that is partly elongated in an oblique direction on the left support piece 12 a in FIG. 1. Here, in the present invention, the piece of paper refers to a relatively thin medium that can be stored in the cover member 10 such as various cards (cash card, IC card, etc.), business card, receipt, or memo piece. . The horizontal width of the slit 15 is preferably formed such that a general-purpose card can be inserted. In addition, although the notch direction of the slit 15 may be horizontal, since the length which presses the inserted paper piece body increases by making it diagonal like this embodiment, it is preferable.

  On the right side of the base portion 11, a laminated body of two resin sheets, a support piece 12 b and a paper piece storage portion 16, is provided with three side outer edges of the two resin sheets in accordance with the periphery of the base portion 11. A piece of paper such as a card C can be accommodated between two resin sheets by welding and welding a predetermined position of the piece of paper containing portion 16 to the support piece 12b in a line.

Next, the structure and manufacturing process of the pen holder part 13 will be described with reference to FIGS.
As shown in the developed view of FIG. 2, the pen holder portion 13 has a shape in which a taper is provided at an end portion of the belt-shaped resin sheet, and the diagonal portions have the same tapered shape. Specifically, the upper left and lower right tapers 13a in FIG. 2 have the same shape, and conversely, the lower left and upper right tapers 13b have the same shape.

  Further, butts 13c and 13d are formed on the left and right sides of the pen holder portion 13, respectively. Further, a bar-shaped stamp 13e is formed in the center of the pen holder portion 13 in the vertical direction. The end of the embossing 13e has a length that does not reach the outer edge of the pen holder 13, and this makes it easy to bend and flatten the pen holder 13 and at the same time does not emboss the outer edge. Strength can also be secured. The embossing 13e does not need to be formed if the material of the pen holder portion 13 is easy to bend or the like.

  In FIG. 2, a vertical line 13 f drawn with a one-dot chain line represents a line serving as an outer edge portion of the cover member 10 after welding, and vertices 14 a to 14 d are vertices between the base portion 11 and the pen holder portion 13 after welding. (Intersection).

  FIG. 3 is a diagram of a process of welding the pen holder portion 13. FIG. 3A is a view when the pen holder portion 13 is set to be welded to the base portion 11. FIG. 3B is a schematic cross-sectional view of the pen holder portion 13 portion. FIG. 3C is a view in which a predetermined position of the pen holder portion 13 is welded by a high frequency welder along the outer edge portion of the base portion 11, and the butts 13c and 13d that are unnecessary portions are fused and separated.

Here, the abutment 13 c and the abutment 13 d of the pen holder portion 13 serve as abutment guide when the pen holder portion 13 is welded to the base portion 11.
The pen holder portion 13 is bent and welded from the center portion. When the pen holder portion 13 is set on the base portion 11, the corner portions of the abutment 13c and the abutment 13d are folded and overlapped to be set as shown in FIG. When this is done, as shown in the cross-sectional view of FIG. 3 (b), the intersection of the resin sheet of the pen holder 13 and the outer edge of the base body 11, that is, the apexes 14a to 14d must be set securely without overlapping. There is an advantage that can be.
As a result, when welding as shown in FIG. 3 (c), the effect of the present invention is that it is very difficult to set the processing conditions at the time of welding because the thickness of only the overlapping apex portion suddenly increases. Thus, the pen holder 13 can be reliably welded.

  Further, the taper 13a and the taper 13b provided on the pen holder portion 13 are very difficult to peel off because the welded portion has a taper shape, and thus tensile stress such as torsion can be dispersed. Therefore, the thickness of the resin sheet can be reduced compared to the case where the base body and the pen holder are welded at right angles, such as the pen holder provided in the conventional notebook cover as shown in FIG. Since it is not necessary to use a strong sheet material, the manufacturing cost can be reduced.

  In the embodiment of the present invention, as an example of a cover member, a pen holder portion that is easily welded to the notebook cover and is not easily peeled off is provided, but the present invention is not limited thereto, and the pen holder portion of the present invention may be provided in a resin container or the like. it can.
