Abstract

PURPOSE:To easily manufacture a vase in a short period of time out of a plastic sheet, which can be stored by piling up and make their storage space smaller, by a method wherein softened folding parts are produced by pressing a fold forming hot blade against the expected folding parts of the plastic sheet so as to be folded under hot state into the shape of the vase and held said shape for the predetermined period of time during cooling. CONSTITUTION:A fold forming hot blade 2 is equipped with edges 4, which abut against the excepted folding parts 3 on a plastic sheet 1 and in which rod heaters 5 are imbedded. In addition, a handle 6 is provided at the upper part of the hot blade 2. A frame 7 to position the plastic sheet 1 is formed to a shape, in which the hot blade 2 snugly enters, so as to highly accurately abut the blade edges 4 against the expected folding parts 3 of the plastic sheet 1 at all times. By inserting the hot blades 2, which are preheated by the rod heaters 5, in the frame 7, the expected folding parts 3 of the plastic sheet 1 is pressed by the blade edges 4 of the hot blade 2 and softened so as to form folding parts 8. The softened folding parts 8 is folded under hot state so as to produce the shape of a vase.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for manufacturing a flower vase.

[Conventional technology]

Conventional methods for manufacturing flower vases include injection molding and the like.

[Problem to be solved by the invention]

As mentioned above, conventional methods for manufacturing flower vases involve injection molding or the like, which requires expensive molds. Therefore, if mass production is not done, the cost will be high, but there is also the problem that even if mass production of the same type of flower vases is not done, it will not be possible to meet the diverse tastes of consumers. Furthermore, since the vase is three-dimensional, it takes up space in flower shops and the like to stock the vase.

Therefore, the present invention aims to solve the above problems.

[Means to solve the problem]

In order to solve the above object, the method for manufacturing a vase according to the present invention presses a heated crease-forming blade against the intended fold area of a plastic plate to form a softened fold area, and then The creases are bent while still hot to form a vase shape, and the shape is maintained for a predetermined period of time while cooling to form a vase from one piece of the above-mentioned plastic plate.

[Function] A large number of plastic plates can be stacked and stored compactly. And every time we receive an order for a vase,
This plastic plate is pressed with a hot crease-forming blade to soften the portion where the crease is to be formed, forming a crease, and the crease is bent to form a vase shape. Easy to manufacture and inexpensive.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a vase manufactured by the manufacturing method of the present invention,
As shown in FIG. 2, this vase is made up of two plastic plates 1. T! The plastic plate l has a thickness of 0.
Preferably, it is made of thermoplastic resin with a thickness of 3 to 2.0 mm.

FIG. 3 shows an example of a method for manufacturing a vase.

2 is a thermal blade for forming a crease, and the thermal blade 2 is equipped with a cutting edge 4 that comes into contact with a portion 3 to be folded on the plastic plate 1, and a rod-shaped heater tail is embedded therein. . Further, a grip bar 6 is provided on the upper part of the thermal power source 2. Reference numeral 7 denotes a frame body for positioning the plastic plate 1. The frame body 7 is formed in a shape that allows the thermal force 2 to just enter without wobbling, and the cutting edge always hits the crease area 3 of the plastic plate 1 with high precision. 4... comes into contact.

Of course, you are free to work without using this frame 7.

Then, a power cord (not shown) is connected to an outlet and the power is turned on to heat the rod-shaped heaters 5. Insert the thermal power 2 preheated by the rod-shaped heater 5 into the frame 7,
Holding the grip 6, the cutting edge 4 of the thermal force 2 is pressed against the crease area 3 of the plastic plate 1 to soften it, and the crease part 8 is formed in the crease area 3. ... is formed (fourth
Next, as shown in FIGS. 4 to 6, the softened folds 8 are folded while still hot to form a vase shape.

That is, as shown in FIG. 4, the diagonal line 9 of a part of the corner...
Bend it inward and insert the plastic plate 1 in the center.
The enclosing line 10 surrounded by straight lines parallel to the outer periphery of is bent inward. Then, as shown in FIG. 5, a part of the protruding corner is bent in the direction A to form a vase shape as shown in FIG. 6. Thereafter, it is cooled for a predetermined period of time while maintaining its shape, and the softened folds 8 are hardened to complete the vase (see Fig. 1). FIG. 7 is an enlarged view of section B in FIG. 6. In addition, to hold the shape during the time until it cools and hardens, it is necessary to hold it by hand or use a jig, for example, a clamping tool 12 as shown in Fig. 1 is used. is also preferable. The clamps 12 may also be used as decorations and used as flower vases while being attached as they are.

In addition, when the plastic plate 1 is heated, the area around the fold 8 may change color and a discolored area 11 may be formed as shown in FIG. 8, so it is preferable to heat the side that will become the inner surface of the vase. .

Note that the present invention is not limited to the embodiments described above, and design changes may be made without departing from the gist of the present invention. For example, the shape of the plastic plate 1 as a raw material and/or the shape of the cutting edge 4 of the thermal force 2 may be varied to change the crease 8 to form a vase with a circular or polygonal flat surface. Further, it is also possible to freely form vases having stepped portions, flange portions, etc., and vases having various other shapes.

〔Effect of the invention〕

Since the present invention is configured as described above, it achieves the remarkable effects described below.

The plastic plate 1 is pressed with the hot blade 2 for crease formation to soften the intended crease portion 3 to form a crease 8, and the crease 8 is bent. Since it is shaped like a vase, it is possible to easily produce vases with a rustic feel or vases with a variety of designs. Moreover, since it is formed from two plastic plates 1, water does not leak.

In addition, it is economical because it does not require expensive molds or the like.

Furthermore, since vases can be easily manufactured in a short period of time, the vases can be manufactured just before they are sold, and when storing inventory at a flower shop, etc., they can be stored stacked in plastic plates 1... , inventory doesn't take up much space.
