Description

The present invention relates to an air cushion package.

For fruits and vegetables, packaging such as containers such as trays, plastic films, foam sheets, etc. is the mainstream. However, in such packaging, damage is generated due to external impact or self-weight, and the commercial value is easily lost. In addition, the packaging form is limited, and there is a problem that it is difficult to differentiate from other products.

In addition, in the case of fruits such as apples, melons, and mangoes, it is necessary to consider measures against spoilage gas generated from fruits as well as the occurrence of damage caused by external forces.

On the other hand, a package that exhibits a cushioning property by forming a plurality of air cells with an airtight sheet such as a soft synthetic resin sheet and enclosing the air in the air cell is due to its excellent buffering function and ease of volume reduction. It is used for protecting and storing various packages. Specifically, as shown in Patent Documents 1 and 2, a buffer bag is known in which a sheet body including an air cell is formed in a bag shape, and an article to be packaged is placed in the bag.

However, it has not been an exaggeration to say that the conventional buffer bag has not been sufficiently improved in the opening structure, and that the tamper-proof function is untouched. For this reason, in order to provide the anti-tampering function, a separate anti-tampering seal is used together, or the open part is completely closed with a heat seal or the like.
Moreover, since it is bag-shaped, it is difficult to view the packaged object directly from the outside, and it is substantially difficult to display it in a packaged state. Further, since the packaging form is such that the flow of air inside and outside is hindered, when the packaged item is a fruit, the spoilage gas generated from the fruit may accumulate in the buffer bag, which may promote a decrease in freshness. is there.

However, a single synthetic resin sheet may be folded. In addition, examples of the material of the synthetic resin sheet include polyethylene, polypropylene, and the like. The synthetic resin sheet is formed by laminating a plurality of synthetic resin sheets, or by laminating a synthetic resin sheet and a metal foil. A composite laminate material may also be used.

The air filling sheet 11 includes an air supply port 13 for filling the air chamber 12 with air. The air supply port 13 is provided at an arbitrary position of the air filling sheet 11. When the air chamber 12 is filled with air from the air supply port 13 to expand the air chamber 12, the air filling sheet 11 does not have to be extended. In the present embodiment, a check valve is used as the air supply port 13, but a valve structure may not be used as the air supply port 13. In this case, the outer periphery other than the peripheral portion of the air filling sheet serving as the air supply port 13 is heat-sealed, air is filled from the air supply port 13 into the air chamber, and then the peripheral portion of the air filling sheet is heat-sealed to air. Can be enclosed.

In the present embodiment, the entire air buffer package is configured by the air filling sheet 11, but at least the locking portion 21 may be configured by the air filling sheet 11.

(Center)
The air cushion package includes a central portion 41 between the locking portion 21 and the receiving portion 31. The central part 41 corresponds to a part for packaging an object to be packaged. The central portion 41 is preferably filled with air and expanded like the locking portion 21, but may be used in a non-expanded state without being filled with air.

In the present embodiment, boundary portions 51 and 52 by point seals are provided between the locking portion 21 and the receiving portion 31 and the central portion 41, and the locking portion 21, the central portion 41, and the receiving portion are provided by the boundary portions 51 and 52. 31 may be partitioned. Here, the point seal refers to something that partially heat seals the synthetic resin sheet constituting the air filling sheet 11 and that does not hinder the air flow in the air chamber 12. In the present embodiment, the boundary portion 51 between the locking portion 21 and the central portion 41 is directed from the left and right sides toward the center so as to cross the longitudinal direction of the air-filling sheet 11 except for the portion that hits the neck. The boundary portion 52 between the receiving portion 31 and the central portion 41 is heat-sealed, and alternately provided with heat-sealed portions and non-heat-sealed portions so as to cross the longitudinal direction of the air-filling sheet 11. It is point-sealed to extend linearly.

In order to divide the central part 41, a partition part 42 by a point seal may be provided. In this embodiment, in the vicinity of the center of the central portion 41, a heat-sealed portion and a non-heat-sealed portion are alternately provided so as to cross the longitudinal direction of the air-filling sheet 11, and a point seal is provided so as to extend linearly. The two partition parts 42 and 42 are provided. By these two partition parts 42, 42, the central part can be bent.

The central portion 41 may be provided with a plurality of window portions 43. In the present embodiment, in the unfolded state, one window portion 43 is provided at each of the upper and lower centers separated by the two partition portions 42, 42, and these window portions 43 are provided in the air filling sheet 11. Is formed by performing ellipse punching processing and then heat-sealing the periphery of the extracted ellipse with an ellipse seal portion 44.

In a non-expanded state before filling with air, the center part 41 is arranged along the outside of the article to be packaged 61 and the head 22 is inserted into the locking hole 32 so that the left and right sides are opened 46. The body 45 is configured, and the window portions 43 are located on both front and rear sides of the annular body 45 separated by the two partition portions 42 and 42.

The neck portion 23 is connected to the central portion 41. In the present embodiment, the locking portion 21 has a “T” shape as shown in FIG. 1. Further, the head 22 may be provided with a burr 24. Here, the burrs 24 are places where resistance is partially received when the head 22 in an expanded state is pulled out from the locking holes 32. For example, as shown in FIG. A concave burrow 24 may be provided at the root, or a convex burrow may be provided at the tip of the head 22 connected to the neck 23, and the vertical width of the head 22 is changed by the burrs 24. By providing the burrs 24 at the base of the head 22, the burrs 24 are locked in the locking holes 32 in a non-expanded state before being filled with air, as shown in FIG. 2. In the present embodiment, the head portion 22 and the neck portion 23 are separated by the slit 25 inserted in the boundary portion 51, but a thick groove may be provided instead of the slit 25.

(Receiving part)
The receiving portion 31 includes a locking hole 32 that receives the head portion 22 and an outer edge portion 33 around the locking hole 32. The outer edge portion 33 is preferably filled with air and expanded like the locking portion 21, but may be used in an unexpanded state without being filled with air. In the present embodiment, the locking hole 32 is formed by removing an ellipse from the synthetic resin sheet constituting the air-filling sheet 11 in the same manner as the window 43, and then surrounding the extracted ellipse. Is formed by heat sealing at the oval seal portion 34. The locking hole 32 may be a slit.

Since the locking portion 21 is constituted by the flexible air-filling sheet 11, the locking hole 32 may be larger or smaller than the neck portion 23. Further, the locking hole 32 is smaller than the head portion 22. When the head 22 is received by the locking hole 32, the non-expanded locking part 21 is inserted into the locking hole 32 in a state of being bent and reduced. Since the latching | locking part 21 is comprised by the sheet | seat 11 for air filling which has a softness | flexibility, it can be bend | folded. FIG. 3 is a development view of the air cushion packaging body according to the present invention, and shows a state where the locking portion 21 is folded in three. In FIG. 3, the boundary portion 51 on the locking portion 21 side is simply described.

(how to use)
In use, first, the article to be packaged 61 is arranged along the non-inflated central portion 41. Next, when the non-expanded head 22 is inserted into the locking hole 32, the non-expanded head 22 is caught in the locking hole 32, but the non-expanded head 22 is caught in the locking hole 32. In this state, the air chamber 12 is filled with air from the air supply port 13 and expanded. In the present embodiment, since the entire air cushion package is constituted by the air filling sheet 11, all of the locking portion 21, the central portion 41, and the receiving portion 31 are filled with air and expanded. In the expanded state, at least the locking portion 21 is less flexible than the non-expanded state, and is hard to be deformed and hard. Therefore, the head 22 is structured to be prevented from coming off from the locking hole 32, and is expanded. The head 22 in the state is locked in the locking hole 32. The state in which the head portion 22 in the expanded state is locked in the locking hole 32 is a state in which the air buffer package is sealed. Further, in the present embodiment, the outer edge portion 33 is also expanded, and the outer edge portion 33 is also less flexible and harder to deform than the non-expanded state, so that the locked state is strengthened. In the present embodiment, the front and rear sides of the annular body 45 in a state where the central portion 41 expands and the packaged object 61 is held in the annular body 45 and the packaged object 61 is held in the annular body 45. The window part 43 is located in the window part, and a part of the package 61 is exposed from the window part 43 to the outside. In FIG. 4, the perspective view which shows the use condition of an air buffer package is shown.

When the center portion 41 is used in a non-expanded state without being filled with air, the article to be packaged 51 is held in the annular body 45 in a non-expanded state.

(Retaining structure)
In the present invention, the air chamber 12 is filled with air from the air supply port 13 with the non-expanded head 22 inserted into the locking hole 32 and the non-expanded head 22 caught in the locking hole 32. A state in which the expanded head portion 22 prevents the locking hole 32 from being removed by a simple operation of forming a structure in which the expanded head portion 22 prevents the locking hole 32 from coming off. That is, the locked state of the locking portion 21 and the receiving portion 31 can be obtained, and this locked state can be reliably maintained. To release the locked state, the air buffer package is broken, the inflated head 22 is pulled out from the lock hole 32, or the air filled in the air chamber 12 of the air buffer package is supplied with air. However, when the inflated head portion 22 is pulled out from the locking hole 32, the inflated head portion 22 prevents the locking hole 32 from coming off, and the non-inflated head portion is pulled out. As compared with the case where 22 is pulled out from the locking hole 32, resistance is generated at the time of pulling out and it is difficult to pull out. In addition, it is desirable that the air filled in the air chamber 12 cannot be removed from the air supply port 13 by heat sealing the check valve after the air buffer 12 is filled with air in the air chamber 12.

(Tamper-proof structure)
Further, according to the present invention, if the head 22 in an inflated state is forcibly pulled out from the locking hole 32 in order to release the locked state, the locking hole 32, the neck 23, and the head 22 are broken. It can also be implemented as a tamper-proof structure. The structure for preventing tampering of the package according to the present invention is a structure for preventing tampering used in the above-described air buffer package, and at least the locking portion 21 is constituted by the air filling sheet 11 so that the head in a non-expanded state. 22 is inserted into the locking hole 32, and the locking portion 21 is filled with air to form a structure in which the head portion 22 expands and does not come out of the locking hole 32. The structure in which the head portion 22 expands and does not come out of the locking hole 32 is configured such that when the head portion 22 in an expanded state is pulled out from the locking hole 32, the package is broken by the resistance generated when the head portion 22 is pulled out. Therefore, the function of preventing tampering with opening the package is exhibited.

From the viewpoint of preventing tampering of the air buffer package, it is better to break the bag, but considering the physical properties such as the impact resistance of the air buffer package, the engagement portion 21 and the receiving portion 31 It is necessary to give appropriate strength in the locked state. Depending on the purpose of use of the air cushion packaging body and the tamper-proof structure of the packaging body according to the present invention, the material constituting the air cushion packaging body and its thickness, the vertical width of the head portion 22 connected to the neck portion 23, the air filling sheet 11 By adjusting the width and the like of the heat seal to be applied, it is possible to impart an appropriate strength to the air buffer package.

Further, the annular body 45 has openings 46 on both the left and right sides, and further, a part of the package 61 is exposed to the outside from the window 43, so that the internal package 61 can be directly observed from the outside. At the same time, when the air permeability is ensured and the fruits and vegetables, especially the fruits, are used as the packaged object 61, the generated rot gas can be diffused from the openings 46 and the windows 43.

In addition, the production method of the air buffer package according to the present invention is not particularly limited. In the present embodiment, the air filling sheet constituting the air cushion package can be formed on the synthetic resin sheet by a conventional processing method called punching and heat sealing including point sealing.

(Other embodiments)
The air buffer package according to the present invention can be implemented with various changes according to the size and shape of the article 61 to be packaged. For example, the lateral width of the head 22 may be shortened or the shape of the head 22 may be different within a range in which the locked state of the locking portion 21 and the receiving portion 31 can be maintained. The shape of the burrs 24 can be variously changed, and an example thereof is shown in FIG.
Further, the central portion 41 and the receiving portion 31 are configured by using a package made of a hard material such as hard plastic, and only the locking portion 21 is configured by the air filling sheet 11 and expands by filling with air. It is good.
Further, as shown in FIG. 6, in the air cushion packaging body constituted by the air filling sheet 111, the center portion 141 is subdivided by heat sealing with the vertical seal 142, and between the vertical seals 142. An air cell structure in which the cells 143 and 144 are formed may be employed. In FIG. 6, an inflatable cell 143 having two check valves 115 between the vertical seals 142 and one non-inflatable cell 144 between the inflatable cells 143 are provided. In this embodiment, instead of heat-sealing the entire circumference of the air-filling sheet with the seal portion 116, a predetermined portion may be heat-sealed with the seal portion 116, and in the width direction of the expandable cell 143. A bent portion 145 may be provided as a point seal. The bent portion 145 has a width smaller than the lateral width of the expandable cell 143 and does not hinder the air flow in the air chamber 112. These bent portions 143 allow the central portion 141 to be bent. Further, in this embodiment, air is introduced from the air supply port 113 on one end side of the air passage 114, and the air is passed through the check valve 115 to the inflatable cell 143 and the locking portion 121 connected to the inflatable cell.
