Description

  The present invention is an auxiliary tool for hanging packaging using an elastic film such as a polyurethane elastomer-based thin film.

  Although there are various types of product packaging, the hanging packaging made of polyurethane elastomer film, which has recently become widespread, is different from conventional packaging, and it is a cushioning pad such as a sponge sheet, air-filled sheet, chain bag, or molded polystyrene foam. It can be said that this method is preferable because it can be reused without using consumables.

However, it seems that the device as a wrapping device, that is, the ingenuity in the processing of the wrapping work, is lacking, and the solution of this seems to promote the spread of the hanging method. From this point of view, let's look at the following literature on typical hanging packaging methods.
In addition, in order to avoid redundancy of description, in the following description, an elastic film material represented by a polyurethane elastomer-based film or the like will be simply referred to as a sheet or a film by a name used in the literature.

JP, 10-258832, A A method of fixing an object to be packed by a facing sheet can be greatly evaluated as a method of fixing and buffering a long package that can be applied to containers such as liquids and powders, and there is no need to mold to the shape of an article. I point out the points and feel the same. However, I feel that it is regrettable that an auxiliary separate support stand must be prepared to fix the packing position.

Japanese Patent Application No. 11-3933 Japanese Patent Application Laid-Open No. 11-3933 A standard facing sheet in which objects having a sheet attached to a rectangular frame having a window are opposed to each other, and the objects to be packed are suspended so that the sheet surfaces are in close contact with each other. Although it is a close contact method, it can be said that it is a masterpiece that reminds us of the difficulties of joining sheets to a rectangular frame such as cardboard.

Japanese Patent Application Laid-Open No. 2001-192067 The textbook is generalized, and it is worth mentioning that it is an introduction text of the method of hanging and wrapping the sheets by the sheet closing and close sheet contact method and the method of fixing the object to be packed by the opposite sheet. There are some doubts in each of the figures that are modeled as if they are weightless, and it may be a problem to be anxious about referring to the posture in which the package is actually stored. .

JP, 2003-275509, A Document 2 is specialized in opening and closing of a bag, and the convenience that a conveyance container is a bag as it is can be evaluated. However, although this figure also contains some inconsistencies, such as a model that describes a model of weightless packaging that is impossible in reality, it is carefully described as a typical example of hanging packaging. However, when looking at the elaborate structure of the frame to which the sheet is to be attached in the description of this gazette, the case where the personal computer is carried at such a high cost is not about an emergency, and how long does this sheet hold in such a case? I am worried, I feel sorry for the explanation of the sheet exchange and feel sympathy for the person who exchanged it. As a result, it can be judged that it is expensive to use in normal times and poor in regularity.

Although it can be read as the heavy goods packaging plate of Patent Document 3, it seems that the emphasis is placed on the structure of the support frame rather than the sheet, and it is a matter of concern that the attitude and position control during transportation of the packaged object are not mentioned.

The above five documents can be said to be teachers on the contrary to the present invention.
When using the usual suspension method,
Literature 1 says that maintaining the posture of the packaged object during transport is not guaranteed, and Literature 5 implies that it is common to have no viewpoint on measures against it.
Document 2 states that it is difficult to bond the sheet to the cardboard,
Literature 3 gives an impression of the attitude of the packaged object when it is impacted,
Reference 4 can also be read as a warning against increased costs and reduced usability due to excessive stiffness.

  The problem to be solved by the present invention is to enhance functions that are considered to be missing from the above-mentioned documents. It is possible to control the suspended posture of the packaged item to a desired state without weakening the buffer function, and it is not explicitly stated in the above documents, but it can be folded at the time of return for economical reuse and the transport volume can be reduced. The two.

  It is no different from the above-mentioned document to make a package in which a flexible and transparent polyurethane-based elastomer film is adhered to a support frame facing each other so as to insert the package and suspend it, but it is the same as the above document. The two pieces were joined together by a substitute for a spacer to form a shell-like shell capable of wrapping the package by folding in two, and a plate piece capable of lightly holding the four corners of the package was provided.

The embodiment of the packaging device of the present invention This embodiment is referred to as the buffering assisting device 3 of the present invention in which the article to be packaged 1 is matched to the size of the inside of the packaging container 2 as shown in FIG. By dropping into the packing container 2 to be put in a shell, the user can easily put the package 2 while looking at the packaged item 2 without selecting the type of the packing container.
Note that a group of thin dashed lines around the packing container 2 in this drawing will be described in detail at the end of [Example 1] described later.

The conventional operating procedure is to first lay cushioning material for cushioning, then place the package or package in a bag approximately in the center, pack the cushioning material around it, and place the cushioning material on the top row again for cushioning purposes. The procedure of covering with cushioning material and closing with a lid at the end, when adopting the product of the present invention,
1) FIG. 2: Folding of the packaging aid before packing As shown in the external view of the folding package, when the two window plates 36 in the center of the layer where the packing aid is folded are opened,
2) FIG. 3: As shown in the perspective view of the cushioning wrapper at the time of preparation for packaging, the bag is opened, so the article to be wrapped is placed in the center of the lower flat surface, and closed in the direction of the arrow E.
3) The buffer packaging device having the shape illustrated in the upper part of FIG. 1 can be dropped into the two packaging containers, and then sealed with the lid.

  In short, while the three actions of opening the packaging, placing the packaged product, and closing it, spread the cushioning material flat on the bottom, pack the cushioning material evenly around the packaged product, and place the cushioning material on top of it. Since the conventional work of thinking or giving a skill to a person required for the packing operation can be eliminated, there is an advantage that labor can be saved or an inexperienced person can substitute.

  In the shock-absorbing packaging device of the present invention, the hanging posture control of the article to be packaged 2 is stabilized by integrating the two film supporting frames opposed to each other via the spacer. In addition, the cushioning ability can be improved by lightly pressing the four corners of the packaged product 2, and further, a sense of security that the packaged product 2 is constantly visible during the packaging operation can be achieved.

  As shown in FIG. 4: a plan view of the main body plate of the buffer packaging device according to the present invention, an inner fold in which a film supporting frame found in a conventional document is disposed on both sides of the waist plate 35 with a waist plate 35 instead of a spacer. 45, but a formwork which is conventionally provided on the entire periphery of the support frame is arranged, and the side plate 32 and the packaged product 2 which hold the support frame, the container up and down, and the height at which the film floats in both upper and lower directions. Is changed to a square presser 31 that can press the upper and lower four corners of the device.

  This will be described with reference to FIG. 4: a plan view of the buffer packaging device main body plate. As is common to all the drawings of the present invention, the folding line is divided into two and displayed. The short dashed line is for bending in the direction of the back of the figure, and the long dashed line is for bending to the front of the figure. This figure is also a development view of the main body plate of the cushioning packaging device 3.

  The main body plate of the cushioning packaging device 3 is made of one corrugated cardboard or plastic corrugated cardboard, has a window plate 36 on both left and right sides of a waist plate 35 in the center of the figure, and an inner waist plate 37 and an outer waist plate 38 outside thereof. When they are connected at the fold 45 and folded in four, a thin box-shaped frame shown at the right end of FIG. 6: external view of the buffer package can be formed.

  Each of the two window plates 36 has a rectangular protruding plate on each of the upper and lower sides. The side plates 32 can be tri-folded in a Π shape by two notches 42 and two push plates 31 and two side plate folds 43. And a portion composed of a side plate 33 and a side plate hem 34.

  A rectangular cutout window 39 is provided at the center of each window plate 36, and a short edge plate 40 and a long edge plate 41 which can be bent to the rear side of the development surface by edge cutouts 46 and edge folds 46 provided radially on four sides thereof. Are located. These become eight guides surrounding the packaged article 1 suspended in the window, the function of which will be described later in the section [0024].

  Since the main body plate of the cushioning wrapper 3 cannot be hung as it is, as shown in FIG. 5: a configuration diagram of the buffer wrapper, an adhesive is printed on the inside of the outer periphery of each window plate 36 in a portion indicated by a dotted line hatching. Then, an elastic elastic film 50 which covers almost the whole of the two window plates 36 and the intermediate waist plate 35 is laid from above and adhered. Although not shown in this figure, it goes without saying that the bonding aging time can be shortened by irradiation of ultraviolet rays or infrared rays depending on the selection of the adhesive 49 used at this time.

  The main body plate of the cushioning wrapping device 3 configured as described above can be formed as shown in FIG. 6: External view of the buffer wrapping device. However, this is not an assembling operation but an operation procedure before origami work. . Thus, in the form illustrated in FIG. 1, the advantages mentioned in the above [0014] stage can be utilized.

  A description will be given of the problem of the present invention, in which the suspended posture of the packaged object can be controlled to a desired state without weakening the buffer function. Compare the sheet with a rectangular support frame with a window, but it is a drawback common to the above cited documents. In the standard counter-sheet-contacting method of suspending the packaged object, regardless of whether the packaged item is drawn as having no weight or being in a zero-gravity space, it is ignored according to FIGS. Proceed with the explanation.

  FIG. 8: The internal cross-sectional view at the time of the vertical installation shows that the thing which put the buffer package 3 in the container box 22 of the packing container 2 in FIG. In FIG. 1 (BW), the internal condition of the package is shown by the weight of the package when installed horizontally, and in FIG. 1 (CW), the package is shown by the weight of the package when installed vertically. It corresponds to the vertically long cutting direction C.

  As can be seen in the (BW) and (CW) diagrams, the packaged articles 1 suspended by the elastic films 50 on both sides are held in a state of being lowered below the center by their own weight W, but they are support frames. Since the window plate 36 is opened with the width of the waist plate 35, the packaged article 1 can be stably held even by the small short edge plate 40 or the long edge plate 41. This is advantageous because the support frame to be brought into close contact with the film 50 has a long hanging portion of the film 50, so that the lateral movement of the film 50 due to vibration is large. Further, since the tension applied to the film 50 is reduced, the operating life of the film 50 is extended. In other words, a conventional polyurethane elastomer having a small tensile strength can be used satisfactorily.

  Also, when an impact force F exceeding the set expected range is applied, a (BF) diagram shows an impact when the setting exceeds the setting in the horizontal installation, and a (CF) diagram shows an impact when the setting exceeds the setting in the vertical installation. In addition, the short edge plate 40 and the chopping plate 41 which are bent nearly horizontally function to support the article to be packaged 1 and function so that the deformation of the material of the window plate 36 as the frame material absorbs the impact force. In addition, since it is supported on two legs, the left and right inclination is small, and the left and right vibration energy is considerably offset by the square pressing plate 31 holding the four corners. This is an effect that cannot be expected with the opposing sheet contact method.

  Before the impact force F per unit area, the impact acceleration is lost to some extent due to the bending of the square pressing plate 31 and the impact force is reduced to a low impact force and hits the short edge plate. As a result, the effect that the impact force is considerably reduced is expected. it can. This can also be said to be an effect that is not recognized in the opposed sheet close contact system. Even if it can be said that these vibrations and tilts of the processed product can not be compared because they are not described in the cited document, even if the polyurethane elastomer material with an extremely low slip coefficient is used, the packing should be placed flat. If not, the packaged product will be in contact with the support frame and will not be touched, so the conventional hanging method is more effective than the one-handed hanging cushioning package. It can be concluded that effective buffer function enhancement was realized.

  Figure 7: When the horizontal placement emphasized by the standard facing sheet adhesion method is shown in Fig. 7 (AW) diagram showing the package's own weight in the internal cross-sectional view when flat, However, since the square push plate 31 which pushes all the corners only slightly touches the vertical vibration of the packaged article 1 to some extent, it is not seen to improve the buffering capacity with respect to its own weight F. However, as shown only in the case of an impact exceeding the setting (AF), the bending deformation of the square pressing plate reduces the acceleration of the packaged article 1 to the bottom of the container box 22 due to the impact force F. This works in the same way when an impact is applied to the ceiling side of the container box 22, that is, the container lid 21, and thus exhibits a certain buffering function.

  In the above, the packing container 2 was hardly mentioned, but the buffer packing functions as long as the container is not broken. If the packing container is stronger than a normal cardboard box, such as a plastic container, the buffer packing of the present invention is used. The tool 3 does not need to form a support frame that seems to be too strong as in the cited reference 5. In other words, it is finally added that the expected cushioning ability can be expected even with a low-strength support material, and that further cost reduction can be promoted by enriching design materials.

(1) The product to be packaged 1 is stored in the buffer packaging device 3 which is a shell that can be folded and opened in two, and is transferred to the packaging container 2 without any other cushioning material.
(2) Since the article to be packaged 1 is simply placed in the buffer package 3 which is a shell that can be opened and closed in two and transferred to the packaging container 2, packaging can be simplified, and the number of packaging steps can be greatly reduced.
(3) The quality of the packing operation is improved because the article to be packaged 1 can be seen until the lid is closed.
(4) The buffer function was strengthened compared to the conventional suspension method.
(5) It is possible to eliminate the trouble of specifying the package style at the time of transport as in the conventional hanging method.
(6) A thin package that is easy to use repeatedly can reduce transportation costs when returning.
You can expect such effects.
