Description

[Detailed description of the invention] The present invention relates to a net-like packaging body, in particular, it is made of a foamed thermoplastic cylindrical net of a certain length, the opening at one end is gathered together in a sphincter shape, and the adjacent outer cakes and stripes are bonded together. The present invention relates to an improved net-like packaging body which has a bottom portion formed by a plastic wrapper, has a good appearance, and has high commercial value.

Various types of net-like packaging bodies are mainly provided for wrapping fruits.

Tubular mesh packaging bodies made of foamed resin strings are used not only as a cushioning material during transportation, but also to increase the value of products when placed in stores.

For example, when you see a red apple packaged in a tube-shaped mesh package made of glossy white foam resin strips, you can understand that it not only gives a sense of cleanliness but also enhances the commercial value of the packaged item, such as fruit. be done.

In a foamed thermoplastic resin tubular network formed by diagonally intersecting inner and outer filaments, if the thickness of the inner and outer filaments is equal, if the bottom is formed with one end open, the adjacent When trying to gather the outer striations in a sphincter shape so that they touch each other, the inner striations are of the same thickness and the same number of striations, so the inner striations protrude and only the outer striations are aligned and glued together. It is extremely difficult to do so.

Due to this difficulty, it is difficult to form a bottom shape that is assembled into a sphincter shape and has a good appearance.

The purpose of this invention is that when the outer filaments are gathered together in a sphincter shape to form an opening at one end, which would normally be the bottom, it is easy to finish the exterior with a good appearance. To provide a net-like package which is thicker than the strips and has openings with good appearance formed by adhering adjacent stripes using only the outer stripes without being restricted by the inner stripes in any way.

Another object of the present invention is to provide a net-like packaging body that uses fewer materials and provides useful effects.

In the present invention, in a foamed thermoplastic resin cylindrical network having a constant length and formed by obliquely intersecting inner and outer filaments, the diameter of the outer filament 1 is equal to the diameter b1.2 to 3 of the inner filament 2. 0 times, and the outer foamed filament 1 is formed at one end opening 3 of the cylindrical mesh.
However, with the opening 3 open, the adjacent outer foamed filaments are brought together in a sphincter shape in contact with each other to form a bottom portion 4, and in the bottom portion 4, the outer foamed filament overlaps with the adjacent outer foamed filament. A net-like packaging body characterized in that it is adhesively bonded to
I will provide a.

The present invention will be explained with reference to the drawings as follows.

FIG. 1 is a side view illustrating the mesh packaging body of the present invention, in which 1 is an outer foamed filament, 2 is an inner foamed filament that is thinner than the outer foamed filament,
3 indicates an end opening at the bottom, 4 indicates a bottom, 5 indicates an opening at one end of the top, and 6 in FIG. 2 indicates an object to be packaged.

Since the mesh of the mesh wrapping body of the present invention is diamond-shaped, it can be expanded and contracted freely, and when wrapping an object, it wraps the object with a good appearance as illustrated in FIG.

In the bottom opening, which is a feature of this invention, only the adjacent foamed filaments on the outside are glued together, and since the inner filaments are thin, they do not interfere with the contact of the outer filaments, and are formed neatly and with a good appearance. The condition assumes a substantially circular shape as illustrated in FIG.

If the size of the package is such that it is used as a package for ordinary fruit, the diameter of the outer striations should be 1.2 to 1.2 to the diameter of the inner striations.
3 times, preferably 1.5 to 2 times.

If the diameter of the outer filament exceeds 3.0 times the diameter of the inner filament, the inner filament will be too thin and the adhesion area between the inner filament and the outer filament will be small, resulting in a mesh packaging with weak adhesion. Becomes a body.

If the diameter of the outer filament is less than 1.2 times the diameter of the inner filament, that is, if the inner filament is too thick, the inner filament will protrude and the bottom will look bad.

In the present invention, adjacent outer foamed filaments are preferably bonded together by thermal welding, but they may also be bonded using an adhesive or other known means.

The foamed filaments of the mesh packaging of the present invention are manufactured from a foamable thermoplastic resin, preferably high-pressure polyethylene,
Polypropylene is commonly used.

The molding method can be a known method.

Foamed filaments are not limited to those that are not dyed; if you consider the color of the object to be packaged and choose a color tone that brings it out, you can further increase the product value.

When using the net-like packaging body of the present invention to package objects to be packaged, such as fruits, open the opening 5 at the top of one side and put it in. Although it is a net-like body, it expands and contracts freely, and the bottom part 4 and The openings are substantially circular and have a uniform appearance.

The bottom portion is substantially circular and the package is stably placed.

Not only does it have a beautiful appearance when placed, increasing the value of the product, but it is also effective as a cushioning material during transportation.
