Description

[Detailed Description of the Invention] The present invention provides a novel method for manufacturing a case such as a pencil case, and an embodiment thereof will be explained with reference to the drawings. First, one side is made of a hard synthetic resin material. A core mold 3 is constructed in which a concave groove 1 is provided around the entire periphery except the center of the rim, and the upper and lower sides 2 and 2' of the peripheral surface are tapered with a hole-shaped cross section.

Separately, a pair of inner plates 5 and 5' are made of leather through a slightly narrow connecting part 4, and one inner plate 5 is made with six vertical cuts 6. The strip 7 is inserted into the notch 6 from the front side to the back side or from the back side to the front side, and a writing instrument holding ring 8 is inserted inside the pronated surface plate 5, and the other inner plate is inserted. A pair of notches 92g are vertically provided at 5', and the notches 9,9
A restraining belt 10 is inserted through the inner plates 5 and 5 to form a restraining part 11 such as a piece of paper on the inner side of the inner plate.
' is bent into a U-shape around the connecting part 4, and the inner plates 5 and 5' are concentrically arranged so that the connecting part 4 is located in the groove-free part 12 on the edge of the core mold 3. The slide fastener 13 is brought into contact with the inner surface of the mold 3, and then the slide fastener 13 is engaged with the peripheral part of the groove 1 in the core mold 3, so that the teeth 14 of the slide fastener 13 are fitted into the groove 1. Both ends of the slide fastener 13 are wound around the outside of both ends of the connecting portion 4, and the cloth portions 15, 15' of the slide fastener 13 are bonded to the outer side of the inner plate 5, respectively, and the inner plates 5, 5 are bonded.
A back plate 16 is attached to the outer side of the connecting portion 4 of the back plate 16. Both end edges of the back plate 16 are on the outside of both ends of the slide fastener 13, and both side edges of the back plate 16 are connected to the inner plates 5, 5'. Affix it so as to cover the parts near the parts.

Furthermore, separately from this, a sponge 18 is placed on the upper side of the cardboard core board 17.
And the fabric 19 is superimposed with the same sponge 18 facing downward, and an adhesive (not shown) is applied to the inner surface of the periphery of the core plate 17 and the sponge 1 fabric 19 to form a band-shaped edge tape 20. and both sides 21, 21 of the core plate 17, sponge 18, fabric 19, and edge covering tape 20.
' are sewn together with thread to form a pair of top plate members 22, 22.
', and the top plate member 22, 22' is connected to the inner plate 5.
．． The same surface covering member 22 is arranged on the outside of the upper and lower surfaces of 5′.
. The outer exposed surfaces of the top plate member 22.22' and the inner plate 5.5 are pressed using a pressing member (not shown) by applying the attached part of the top plate member 22.22' to a press device without removing it from between 5'. Cloth portions 15, 15' of slide fastener 13 and back plate 16
After the slide fastener 1 is firmly attached to both side edges of the slide fastener 1,
3 is opened and the core mold 3 is removed to obtain a finished product.

Since the present invention is as described above, it is of course very effective that it can be carried out in an extremely simple manufacturing process, but in particular, the top plate member of the product obtained according to the present invention has a sponge and a sponge on the upper side of the hard core plate. A flexible material such as a fabric is polymerized with the sponge facing downward, and the periphery of the flexible material such as the hard core plate, sponge, and fabric is wrapped with a band-shaped edge tape, and the hard core plate and sponge are wrapped. , constructed by sewing together both sides of a flexible material such as cloth and a hem tape.
Compared to the surface plate member known in No. 659, etc., in which a skin is simply polymerized on the surface of a hard-cored bottle and the peripheral edge is rolled around and attached to the lower surface of a concentric plate, its peripheral edge is It has various excellent effects such as being extremely robust.

Claims (1)

[Claims] 1 A core mold is made of a hard synthetic resin material and has a concave groove around the entire periphery except for the center of one side edge, and a pair of flexible material such as leather is formed on both the upper and lower sides of this core mold through a connecting part. Attach the inner plate so that the connecting part is outside the groove-free part on the periphery of the core mold, and attach a slide fastener that is engaged with the peripheral part of the groove on the core mold. Wrap the slide fastener so that its engagement teeth fit into the groove, and glue both ends of the slide fastener to the outside of both ends of the connection part of the inner plate, and the fabric part of the slide fastener to the outside of the periphery of the inner plate. At the same time, place a back plate on the outside of the connection part of the inner plate so that both edges of the back plate cover the outside of both ends of the slide fastener, and both edges of the back plate cover the part of the inner plate near the connection part. Separately, a flexible material such as a sponge or fabric is polymerized on the upper side of the hard core plate with the sponge facing down, and the flexible materials such as the hard core plate, sponge, or fabric The periphery is covered with a belt-shaped edge tape, and the hard core board, a flexible material such as sponge or cloth, and both sides of the edge tape are sewn together to form a pair of outer covering members on the upper surface of the inner plate and the inner plate. Place the same surface material on the outside of the lower surface and attach it to the externally exposed surface of the inner plate, the cloth part of the slide fastener, and the surface of the part of the back plate that attaches to each inner plate, and open the slide fastener to remove the core. A case manufacturing method characterized by removing a mold.
