2. Description of the Related Art Conventionally, when selling cut flowers or the like, a bouquet is wrapped with a film sheet or the like, and the overlapping portion is stopped with an adhesive tape or the like, or a trapezoidal flower wrapping bag is used. In this case, as a trapezoidal flower wrapping bag, there is a two-layer film sheet manufactured by heat-sealing both side edges of a film sheet (for example, JP-A-11-9).
No. 1846).

[0003]

However, in the above-mentioned method of winding a film sheet, since the sheet is cut out and wound by a unit amount according to the size of the bouquet, the usage amount of the sheet becomes non-uniform and waste is likely to occur. In addition, such a method is troublesome and may damage the flowers themselves.

[0004] On the other hand, those using a trapezoidal flower wrapping bag can solve the above problems, but have the following problems. (1) The appearance is poor and the commercial value of the flower may be hindered. (2) Since there are two heat-sealing seal portions at positions 180 ° apart, when the bouquet is displayed, the heat-sealing seal portions are often visible on the front side, and the appearance is poor. (3) To manufacture one flower wrapping bag, 2
One heat-sealing sealing step is required, resulting in high manufacturing and equipment costs.

[0005] The present invention has been made in view of such conventional problems. Therefore, the technical problem of the present invention is:
It is an object of the present invention to provide a flower wrapping bag formed so that a bouquet can be displayed with good appearance, and a method for manufacturing the flower wrapping bag, which can reduce manufacturing costs and equipment costs.

The present invention employs the following technical means in order to solve the above-mentioned problems.

That is, as shown in FIG. 1, the present invention is a tapered flower wrapping bag 1 having upper and lower ends opened and gradually narrowing from an upper end to a lower end. It is characterized in that it has one vertical heat-sealing seal portion 2 and its upper end is formed obliquely, and the heat-sealing seal portion 2 is arranged at the apex of the diagonal cut 3 at the upper end. (Claim 1).

Since the flower wrapping bag of the present invention has one heat-sealing seal portion (one location), when the bouquet is put in the flower wrapping bag and displayed, the heat-sealing seal portion is arranged on the back side and displayed. Then, the heat-sealed seal portion is hardly seen from the front side, and the appearance is good. Furthermore, in the case of the product of the present invention, when the bouquet is displayed, the cut at the upper end extends obliquely high from the front side to the back side, so that the appearance is improved.

In this case, in the present invention, it is preferable that the upper end is formed to have an oblique waveform. This is because, in this case, the appearance is further improved.

[0010] The method for producing a flower wrapping bag of the present invention is configured as follows.

That is, according to the method of the present invention, a step of heat-sealing the surface layer and the back layer of the tubular wrapping material 10 formed in a belt obliquely over opposing longitudinal side edges, Wrapping material 11 having a heat-sealed seal portion 2 by cutting
And a step of splitting the wrapping material 11 into two along the heat-sealing seal portion 2. The upper and lower ends of the cut and substantially triangular wrapping material 12 are opened at a wide upper end. A step of cutting the lower end into an appropriate shape obliquely from the end of the welding seal portion 2 to the side edge in the longitudinal direction (claim 3).

In the case of the manufacturing method of the present invention, since a heat-sealing seal is obliquely inserted into the tubular wrapping material 10, two substantially triangular wrapping materials 12 can be formed simultaneously by one heat-sealing seal. Therefore, according to this, manufacturing cost and equipment cost can be reduced.

In the method for producing a flower wrapping bag according to the present invention, when the tubular wrapping material 10 is cut in a direction orthogonal to the longitudinal direction, a position separated by a predetermined length D from the heat-sealing seal portion 2 is cut. Is preferable (claim 4).

According to this, even if the drawer roll of the bag making machine slips, it is possible to prevent the cut surface from being applied to the heat-sealing seal portion 2 and the yield is improved.
