Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a packaging body for covering and protecting various cut flowers such as gerberas.

[Problems to be solved by conventional techniques and ideas]

Conventional packaging of this kind is made of plastic film, which is connected at the top and bottom and has a large drainage hole of about 5 mm in diameter. However, when a large number of cut flowers are bundled together, they stick together, impeding ventilation, and when the flowers are inserted, the stems often catch on the large drainage holes and break, making them unusable. In addition, there are products with many micropores, but when moisture adheres to the film, the adsorption force causes the petals and the film to stick together, resulting in poor ventilation, which causes the petals in that area to discolor, reducing the product value. .

[Means to solve the problem]

Therefore, the present invention improves the numerous micropores to provide a device that can ensure air permeability even when they are in contact with each other and is easy to handle. For this reason, the present invention is a bag with a communicating opening at the top and bottom, which accommodates and protects at least the corolla of a cut flower. In addition, small protrusions are provided around the respective micropores on the inner surface of the bag body.

[Effect]

For example, when a hot needle is inserted, a fine hole is made in the film, but when the hot needle is pulled out, the melted polypropylene resin in that area is stretched and shrinks and hardens. A few small protrusions are protruded around the micropores, and the film becomes uneven due to the countless micropores. By using this uneven surface as the inner surface of the package, the small protrusions prevent the petals from coming into close contact with the film, ensuring breathability and preventing discoloration. This enables stable placement with friction locking.

【Example】

Hereinafter, details of the present invention will be explained with reference to illustrated embodiments. The package S of this example shown in FIGS. 1 and 2 has a diameter of
It is made by stacking two 0.025 mm thick biaxially stretched polypropylene films 1 with countless 0.3 mm micropores at equal intervals of 1 mm, and cutting the both ends 1a by heat welding, so that the top and bottom are communicating with each other. It has an inverted trapezoid shape. Note that the micropores K are formed by pressure bonding with a heated roller having a large number of needle-like bodies protruding from the outer periphery, and when the heated needles are pulled out, the melted polypropylene film resin in that area is stretched. By shrinking and hardening at the same time, a small protrusion Ka is formed around each microhole K on the side surface of the hot needle insertion (see Fig. 3). For this reason, one side of the film is uneven, and in this example, the uneven surface of the film is the inner surface. In this example constructed in this manner, as shown in FIG. 4, the stem 2b of the cut flower is inserted through the upper and lower openings, and the corolla part 2a is housed and placed in the package S for covering use. . According to this example, there are the following effects. (a) The small protrusions Ka on the inner surface of the micropores K prevent the petals from coming into close contact with the film 1, ensuring breathability and preventing defects such as discoloration of the petals. (b) Since the petals are locked by the small protrusions Ka of the numerous micropores K, the corolla part 2a can be prevented from shifting, and its shape retention can be maintained well, making it suitable for transportation. Furthermore, because the overlapping films do not come into close contact with each other due to the small protrusions Ka, and by rubbing two fingers in opposite directions, the small protrusions Ka located on the inside can be strained through the outer film. The outer film can be easily peeled off because it is easier to catch on fingers. Because this peelability is good, it is effective to take out each sheet-like package one by one and to open the bag-like package smoothly, which eliminates the troublesome insertion of cut flowers on-site. A major feature is that the packaging work can be done quickly. In addition, since this releasability is good, it is easy to correct the wrapping position when the cut flowers are covered, and an appropriate wrapping condition can be ensured. In addition, in this example, since both ends 1a of the film are thermally welded, when taking out cut flowers from the package S, as shown in FIG. Since the petals are peeled off, they can be easily removed without damaging the shape retention of the petals. In particular, the film can be peeled off more easily since the film has small holes K at both ends 1a, so that the adhesion area is small. In this regard, in the past, the cut flowers were forcibly removed from the package by pulling the stem downward or by moving the package downward, which resulted in the petals pressed to the film becoming deformed or even missing. It was a tedious task. Although this example is configured as described above, the present invention is not limited thereto. The size and shape of the package are not limited, and the package may be made long to accommodate the entire cut flower, as shown in FIG. Further, the arrangement of the micropores is arbitrary, and the size of the micropores is also arbitrary, but a diameter of about 0.2 to 0.5 mm is optimal from the viewpoint of strength.

[Effect of the idea]

According to the present invention, the numerous micropores provide good breathability, and the small protrusions around the micropores prevent the petals from coming into close contact with the film, ensuring breathability, thereby preventing discoloration and the like. In addition to being able to maintain good quality, the small protrusions prevent the overlapping films from coming into close contact with each other, and by rubbing two fingers in opposite directions, the small protrusions located on the inside can be removed from the outside. Since the outer film can be easily peeled off because it can be easily caught on the fingers through the film, it is possible to take out each sheet-like package one by one and to open the bag-like package smoothly, making it troublesome. This method has the great effect of speeding up the cut flower packaging work, and also has the operational advantage of being able to easily correct the packaging position while the cut flowers are covered due to the removability of the package, ensuring proper packaging conditions.
