Abstract

An object of the present invention is to store a three-dimensional storage object inside a plastic package, wherein a flap provided above an opening obstructs the opening, and the opening cannot be greatly expanded. Due to wrinkles and twists, the sealing operation is troublesome, and the sealing operation tends to be time-consuming and complicated. The present invention provides a plastic package in which three-dimensional contents are placed inside such a plastic package, and the sealing operation can be performed quickly and smartly.
The rectangular plastic package has a header provided with a suspension hole at an upper portion of the rectangular plastic package, and has an opening at the lower side of the header. A plastic package body capable of easily sealing contents, wherein an adhesive layer having a predetermined width is formed over the entire length, and the adhesive layer is temporarily fixed by previously adhering a release tape.

Description

The present invention relates to a plastic package which allows a large opening at the upper part of the bag to be opened, which is convenient for taking in and out of three-dimensional items, and which can be sealed with one touch.

Conventionally, as shown in FIG. 8, this type of plastic package is provided with an envelope-shaped flap provided with an adhesive layer on the inner lower surface from the upper edge of the upper opening at the lower side of the header. This was performed by peeling off the release tape temporarily fixed to the lower surface of the flap.

In the case where the opening is provided below, there is a type in which the adhesive layer formed on the inner surface of the flap extending from the front sheet of the opening is bent and adhered to the back sheet of the opening. (For example, Patent Document 1)

JP-A-5-77840

Conventionally, in the above-mentioned Patent Document 1, if the bag body is relatively small in width, the sealing operation is relatively easy even when the adhesive layer is formed on the inner surface of the flap extending from the front sheet of the opening. With such a structure and with a wide opening, a three-dimensional product can be put in and taken out. In particular, in the case of a three-dimensional product in which the contents are bulky, the product is folded to the adhesive layer of the flap, and the adhesive layer of the flap is folded. However, there is a tendency that the packaging of the bag body is not carried easily and the operation is complicated, such as bonding to a place other than the regular bonding portion.

As shown in FIG. 8, even when the flap 30 is formed at the upper opening of the bag body a and the adhesive layer is formed on the inner surface of the flap, a comparison is made between the case where the planar storage items are stored inside the plastic package. However, when storing three-dimensional items inside the plastic package, the flap provided above the opening interferes with the opening, and the opening cannot be widened greatly. Since the adhesive layer can be wrinkled or twisted, the sealing operation is troublesome, and the sealing operation tends to be time-consuming and complicated. It is necessary to put such three-dimensional contents inside such a plastic package, and to quickly and smartly seal the plastic package.

In order to solve the above-mentioned problem, the present invention is directed to a rectangular plastic package having an opening at an upper portion, wherein an adhesive layer having a predetermined width is formed over the entire length of one side of an upper opening of the plastic package. The adhesive layer is formed by attaching a release tape in advance and temporarily fixing the content so that the contents can be easily sealed.

Also, a rectangular plastic package having a header provided with a suspension hole at the top of the rectangular plastic package, and having an opening at the lower side of the header at the upper side, wherein the entire length of one side surface of the upper opening An adhesive layer having a predetermined width was formed, and the adhesive layer was temporarily fixed by previously adhering a release tape.

The rectangular plastic package may be provided with a bottom gusset.

A rectangular plastic package having an opening on the upper side, wherein an adhesive layer having a predetermined width is formed over the entire length of the inner surface of the upper opening of the plastic package, and the adhesive layer is pre-bonded with a release tape. Since the bag is temporarily fixed, the opening of the bag opens widely, making it easy to put in and take out the product, and sealing work at the opening can be done very easily by pulling both ends of the opening of the bag. As a result, the operation of putting the product inside the bag and sealing the product can be processed very efficiently.

A rectangular plastic package having an opening at the upper side, wherein an adhesive layer having a predetermined width is formed over the entire length of one side surface of the upper opening of the plastic package, and the adhesive layer is pasted with a release tape in advance. A plastic package that can easily seal the contents, which is temporarily fixed.

1 to 7, a rectangular plastic package 1 having an opening 2 in an upper portion, and an adhesive layer 3 having a predetermined width is formed only on the inner surface of the upper opening 2 over the entire length thereof. The adhesive layer 3 is temporarily fixed by previously attaching a release tape 4.
A thick header 5 is continuously provided on the upper part of the inner surface of the opening 2 of the plastic package 1. At the center of the header 5, a hanging hole 6 is provided for hanging on a projecting piece for display.

When the opening of the plastic package 1 was sealed, the three-dimensionally stored product b was put inside the plastic package 1, and the opening was still separated as shown in FIGS. 3, 6, and 7. In the state, the release tape 4 temporarily fixed to the inner surface on the side of the adhesive layer 3 is detached, and both sides of the upper end 7 of the opening of the plastic package 1 are grasped with fingers, and arrows are drawn from both ends. If it is pulled in the direction, the opening will have its adhesive layer 3 adhered to the other side of the opening.
That is, the operation of sealing the opening of the plastic package 1 is completed in a moment by peeling off the release tape 4 and pulling both ends of the opening.

In the plastic package which can easily seal the contents of the present invention, the flap is not formed in the opening, so that the opening is greatly opened, so that the taking in and out of the three-dimensional object b and the sealing work become particularly convenient. Things.

Further, FIG. 1 shows a plastic package 1 provided with a bottom gusset 10 on both sides.

In the plastic package that can easily seal the contents of the present invention, the three-dimensional product is wrapped inside the plastic package, and the operation of sealing is performed quickly and reliably, so that the product for display and display is smoothly packed. Since it can be performed accurately, it can be used for packaging various kinds of various products.

It is a perspective view in the state where the upper opening part of the plastic package was opened. It is an expanded longitudinal cross-sectional view of the upper part of a plastic package. It is a perspective view which shows the operation which stores and seals a three-dimensional object inside a plastic package. It is a partially expanded sectional view showing a state before sealing of an opening of a plastic package. It is sectional drawing of the state sealed by the state which accommodated the three-dimensional goods inside. It is explanatory drawing which shows the work procedure which shows the state before sealing. It is explanatory drawing which shows the work procedure which shows the state after sealing. It is a perspective view of the package which shows a conventional example.
