Abstract

(57) [Summary] [Structure] In a bag formed of a polymerized film, the left and right sides of the bag bottom are formed in an arc shape, and the central portion is projected in a semicircular shape with substantially the same radius as the arc. , The product initially stored in the bag is naturally exposed to the central semi-circular part, and the product to be stored later slides along the spherical surface of the first product to the left and right arc-shaped parts of the bag bottom. To face. [Effect] Spherical products to be packaged are kept in a stable state in the bag, are easy to package and transport, and can effectively display space without damaging the products.
Since the total volume of packaging materials is small, there is an advantage that packaging resources can be reduced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bag formed of a polymerized film, and is used when packaging three or more spherical agricultural products such as apples, pears, tomatoes, and tangerines.

[0002]

[Prior art and its problems]

 Spherical products such as tangerines, onions, and eggs in hot water are sold in a thin net bag in a series storage package. However, even if spherical products are required to have an external appearance and appearance, for example, apples, the value of the products will be reduced if they are packed in series, so the products will be lined up on a foam synthetic resin tray and wrapped. It is displayed and displayed. However, the use of a tray made of foamed synthetic resin causes over-packing, causes pollution problems regarding the disposal of the tray, and has a disadvantage that an extra space is required for display.

When an apple is to be packed in a bag formed of a film obtained by polymerizing a spherical product of this type, that is, an ordinary plastic bag, the product becomes a spherical product, which makes it extremely unstable. This will hinder the work, and the left and right sides of the bottom of the bag will protrude in a hollow state, which will hinder the display.

[0004]

[Technical issues]

 An object of the present invention is to enable spherical products to be packaged in a stable state in a bag formed of a polymerized film.

[0005]

[Technical means]

 Technical means for solving this technical problem are as follows: (a) The left and right sides of the bottom of the bag are formed in an arc shape, and (b) the central part is projected in a semicircular shape with substantially the same radius as the arc. That is.

[0006]

[Operation of technical means]

 If the center of the bottom of the bag is projected in a semi-circular shape, the product initially stored in the bag will naturally face this semi-circular shape. Since the left and right sides of the bag are also formed in an arc shape, the next stored product slides along the spherical surface of the first product to face either the left or right arcuate part of the bottom of the bag, and the third Products will face the other side. Therefore, the spherical product to be packaged is kept in a stable state in the bag, and the stable state is not lost even if the opening of the bag is closed.

[0007]

[Effect of the present invention]

 As a result, spherical products can be packaged in a stable state, which facilitates packaging and transportation, and has the advantage that products can be displayed by effectively utilizing the space. In addition, since the storage state of the products is stable and hardly moves, there is no risk that the products will collide with each other and be damaged. Furthermore, since the total volume of the packaging material is small, there is an advantage that the resources of the packaging material can be reduced.

【Example】

FIG. 1 is a front view of a packaging bag 1 according to the present invention, in which two 30-micron-thick films made of polypropylene resin are polymerized and the portion other than the opening 2 is fused and welded to form the bag body 1. Is forming. The arcs 4, 5, and 6 on the left and right sides and the central part of the bottom portion 3 of the bag body 1 are inversely correct with the centers P ₂ , P ₃ , and P ₁ being the same as or slightly larger than the diameter of the spherical product as one side. The arcs are located at the vertices of a triangle, and each arc is drawn with a radius of 1/2 aπ from each center. Therefore, when three apples 7, which are spherical products, were packaged in this bag body 1, they could be properly stored in the arc-shaped storage portions 4, 5, and 6 (see FIG. 3). The above dimensions are for making the gap between apples as small as possible before bundling the opening of the bag, making the arc large to store apples with a margin and to reduce the gap when bundling. It may be done. Since the bag in this form can automatically position the first stored product, it is possible to stably package even more products.
