Description

  The present invention relates to a shock-absorbing clear packaging device having a simple structure with high impact resistance, which can be packaged in a production factory or the like so that the product can be checked from the outside at any time.

  Although there are various forms of product packaging, the products that are individually packaged at the production site are grouped and distributed to collection and delivery factories in each district and transported to sales destinations. The product is confirmed. Therefore, there is a demand for a package that can be inspected for damage to the product at any time, such as shipping, sorting, unpacking, exhibiting, and selling, in terms of ease of sorting and publicity of product appeal.

  At stores, many items are sold in completely transparent plastic film square boxes and cylinders, from pets, jewelry or small electronic devices to sweets, but are not limited to these. In addition, there are many demanded articles that utilize the eye-catching function based on the attractiveness of the product itself, from AV products to toys. However, most of the current situation is a case made of specially molded transparent plastic film that matches the form of the product, and a packaging tool that can handle a wide variety of products as a conveyed object is inexpensive, versatile, but allows the conveyed product to be seen as a product from the outside rare.

No precedent was found for the mechanism of the intent of the present invention, but the following four examples have no mention of the purpose of “viewing the packaged goods from the outside” and are still complex, but can be used to achieve the above goal. Looks like a typical example of packaging.
[Patent Document 3] Japanese Utility Model Registration No. 3063383 [Patent Document 3] Japanese Utility Model Registration No. 3076355 Title of the Invention Product packaging support having a polyurethane film-welding surface for buffer [Patent Document 3] Japanese Utility Model Registration No. 3096592 Patent Document 1: Japanese Patent No. 1198227 Title of the Invention Buffer Holder for Incorporation in Container

  Patent Literature 1 discloses a method in which a conveyed product is inserted in a support frame to which opposed polyurethane films shown in FIG. 3 are attached. In a so-called hanging packaging method, the polyurethane film is attached to the support frame by hot-melt compression rather than by adhesion. Is trying to show that it is more robust.

  Patent Document 2 shows an effort to reinforce a support frame in which a film is hot-melt-compressed for practical use in a hanging packaging system in which a conveyed product is inserted in a support frame to which opposed polyurethane films are attached as shown in FIG. However, this implies that there is a background to the spread of the hanging packaging method.

  Patent Document 3 discloses that in the hanging packaging method in which a conveyed product is inserted in a support frame to which a pair of opposed polyurethane films are pasted, it is not necessary to attach a polyurethane fill to the support frame and to join the entire circumference. This is an epoch-making device that shows that the suspension method is possible with only one polyurethane film, and also shows the versatility by adjusting the support, and also enables the reuse capability, which is the purpose of mailing. It also shows that there is no need for hot-melt compression bonding because there is no support frame.

  Patent Literature 4 discloses that, from the example described in the description section of the article and the reference diagram, only a single polyurethane film attached to only two indicator rods can be used by using a box as illustrated in Patent Literature 3. This indicates that the hanging packaging method is possible.

  The present invention further advances the concept shown in Patent Documents 3 and 4, and achieves a simple mechanism for hanging packaging that can be performed with one sheet of polyurethane film. Therefore, it was aimed to make the packaged product visible from the outside even after the packaging described in [0002] as well as the versatility. For this reason, there are three types of functions to be provided.

  One of the functions basically required for this packaging device is an impact resistance, which is a buffer enough to withstand the distribution and transportation of high-density and low-impact articles such as electronic equipment assembly parts and products. It is intended to be used for packaging plastic and cloth dolls that are bulky and low-density but have many soft or brittle projections.

  The second basic function of the packaging device is not a simple mechanism but a simple configuration, that is, a configuration with as few parts as possible.

  A secondary function of this packaging device is that the packaged article can be seen from outside even after packaging.

  The high impact resistance requirement of the above-mentioned [0010] can be applied to a case of a packaging material and a packaging box of the same size, even if it is a severe case, if it is a thick polyurethane film having a high vibration absorbing power, it can be applied without any problem. Hanging packages that can be easily hung to maintain their position can be used. This can be adapted to a flexible package by reducing the tension of the suspension or by replacing the polyurethane film with a thinner one. Of course, if the tensile strength and the film thickness are appropriate, there is no problem even if the film is a polyolefin film. Either way, it can be empirically said that the hanging packaging form is sufficient.

  The high impact resistance requirement of the above [0010] also affects the strength of the packaging box, but this is a problem of the strength of the packaging component material and the box material, and thus does not affect the configuration of the present invention, and is ignored here. .

  What is required by the above [0011] is to reduce the number of components and to simplify the shape. For this reason, two sets of support frames were required to achieve the conventional common sense of hanging packaging, which is "inserting a conveyed product with a support frame with one set of opposed polyurethane films". Is possible even with one sheet of polyurethane film, which is different from that disclosed in Patent Document 3 and is possible only with one paper board supporting frame. For this reason, although the shape is slightly complicated, the area of the paper board used for the support frame is close to half of the conventional one, so that the amount of consumable material can be significantly reduced.

  In the present invention, the transport product is made into a bag-like shape by folding a polyurethane film, which is rich in elasticity and flexibility, into two in order to withstand vibration, and folding both ends of the lower and lower waist plates of the middle plate outward. By making the film function as a transparent pocket into which the material to be packaged can be inserted, the film can be suspended from the support frame. It can be said that the folding of this film satisfies the conditions of [0010] and [0011]. This is also a simplification of the manufacturing process, which eliminates the need to prepare in advance a bag-shaped film material by cutting a tubular film and thermocompression bonding the bottom.

  The above requirement [0012] requires only that the buffer clear packaging frame wrapping the article to be packaged be placed in a transparent outer box or a box with a window hole that can be seen inside. This is because, as described in [0016], since the polyurethane film acts as a transparent pocket containing the material to be packaged, the material to be packaged is not hidden.

  Figure 1: Example of use of the buffer clear packaging frame As shown in the photograph of the buffer clear packaging frame of the present invention shown at the bottom of the figure, inside the window hole opened in the center of the middle plate that has left and right wings and has a concave front. It can be observed that the packaged object 4 is suspended by the transparent film while the support plate is not visible. This is a proof that [0012] is responding to the requirements in the sentence.

  The case at the top of the figure is a five-sided transparent sheath-like shell box 13 made of polypropylene film with a ceiling that houses the entire buffer clear packaging frame at the bottom, that is, an outer box. According to the present invention, the packaging can be completed with two parts if the articles to be packaged are not counted. Thus, it can be determined that the condition [0011] is sufficiently satisfied.

  FIG. 1 shows that the package 4 as a load is suspended by a transparent film, and thus it can be seen that the anti-buffer function in the paragraph [0010] is satisfied. Since it depends on the size and strength of the outer shell 13 which is a sheath-shaped outer shell box 13, let's put it as it is achieved.

  Let's see the desirable shape conditions such as the size with the outer box in the buffer clear packaging frame. FIG. 2 is a vertical sectional view of a use example of the buffer clear packaging frame, viewed from the direction of arrow B, which is cut along the vertical line AA shown in the lower part of FIG. 1. This is also the best practice model for hanging packaging.

The present invention is roughly divided into two parts.
The first is a buffer clear packaging frame 20, which is not suitable for transportation in this shape as shown in FIG. Therefore, an outer box for protecting the buffer clear packaging frame 20 is required.

  The outer case 2 is a bottomless outer shell box 11 in the upper part of FIG. 3 in which the buffer clear packaging frame 20 can be inserted and stored in the direction of arrow C, which is also the longitudinal direction, and the whole or part thereof is transparent. If desired, a window hole 12 indicated by a two-dot chain line may be provided, and it may be made of an opaque plate. Most preferred is a five-sided transparent shell 13 with a ceiling or bottom, as shown in FIG.

  In addition, as shown in the lower part of the buffer clear packaging frame 20 shown in FIG. 3, a case where the buffer clear packaging frame 20 is placed in a frame-shaped outer shell box 14 surrounding four circumferences, and the upper and lower portions thereof are covered with a transparent shrink tube 15 and thermally shrunk. There is also.

  The sheath-shaped or frame-shaped outer shell maintains the suspended state of the cushioning clear packaging frame 20 of the present invention at the time of packaging the article 4 to be packaged, prevents distortion of the buffer clear packaging frame 20, and prevents deformation by direct external force. Although inevitable to avoid, it does not affect the gist of the invention.

  Now, returning to FIG. 2: a vertical sectional view of the use example of the buffer clear packaging frame, it should be understood that this is also the best practice model of the hanging packaging. The structural details of the cushioning clear packaging frame will be described later in FIG. 4, FIG. 5, and FIG. 6, but the function achievement factors will be described first. The left hand of FIG. 2 is the front of FIG. 1, and the right hand is the back. The left and right plates in the lower photograph in FIG. 1 are upper waist plates 28 in FIG. 2, and the article to be packaged 4 is substantially the same as the hole provided in the center of the C-shaped lightweight rope-shaped vertical cross-section indicated by the hatched line of the buffer clear packaging frame 20. The polyurethane film 30 is suspended in the center by being accommodated in the folded polyurethane film product 30, and both ends of the polyurethane film are fixed by adhesive tape 38 on the back surface of the buffer clear packaging frame 20 at both the upper and lower sides. Although the back surface is not visible in FIG. 1, the photograph of FIG. 1 shows the adhesive-side plate facing the front side in the window, proving the transparency of the folded polyurethane film product 30, while showing the transparency of the packaged product 4. The suspension state is perfect, and also indicates that there is no support other than the film.

  FIG. 2: Example of use of the buffer clear packaging frame The longitudinal section shows that the suspended state of the packaged product 4 is that the packaged product inserted between the two films formed by the folded-up polyurethane film 30. In FIG. 2, the tensile strength of the film itself due to the extension of the film in the front-to-back direction of the film by the product 4 is supported in the center of the buffer clear packaging frame 20, and the tensile strength is supported by the vertical placement of the buffer clear packaging frame 20. The packaged article 4 is held substantially at the center regardless of the posture such as the horizontal position. Further, the height of the coefficient of surface friction selected to meet the main purpose of the present invention, that is, the characteristic of the polyurethane film as a very non-slip material, is shown in FIGS. Unnecessary is ensured.

  This embodiment of the present invention will be described with reference to FIG. The cushioning clear packaging frame 20 is configured by bonding a folded polyurethane film product 30 to a frame material made of a paper board material. In FIG. 4, the polyurethane film material is placed on the upper stage, and the folded polyurethane film product is located on the lower stage. FIG. 5 is a development view of a frame material made of a paper board material in a shape inverted after bonding on the left side, and the folded polyurethane film product 30 after bonding is shown by a thin imaginary line on the right end of the development view.

  Description will be made from the folded polyurethane film product 30 arranged in the upper part of FIG. The sheet obtained by cutting the polyurethane film into a trapezoid is shown in FIG. 4, in which a bottom side 32 composed of angles EF, an upper side 33 composed of angles GH, a right hypotenuse 31 composed of angles FG, and a left hypotenuse 31 composed of angles EH are shown. , And the overall shape is indicated by a developed portion of a virtual line and a folded display portion of a solid line.

  FIG. 4 shows a trapezoidal polyurethane film sheet having four sides of a bottom side 32, an upper side 33, and both hypotenuses 31. A label 37 may be pre-adhered to the center of the upper side 33 and may be placed. Is shown but not a necessity. The upper side 33 is folded on the bottom side 32 at the folding position of the trapezoidal polyurethane film closer to the upper side than the center of the hypotenuse 31. This is shown as folding direction J of the upper right corner of the trapezoidal polyurethane film.

  In this case, the folded polyurethane film becomes a trapezoid having a height of the bottom side left and right hypotenuses 36 slightly larger than half of the hypotenuse 31 before folding, and further has a trapezoidal shape slightly smaller than half of the hypotenuse 31 before folding. The trapezoidal shape of the height of the upper right and left oblique sides 35 overlaps. In this state, it is placed on the unfolded buffer clear packaging frame material and both right and left ends are joined with adhesive tape 38. This is indicated by two thin vertical imaginary lines.

  In the present invention, the polyurethane film before folding is trapezoidal, but the point is that the left and right ends after folding can be joined to the frame material surface with adhesive tape etc., but there is no need to stick to the trapezoidal shape, but the present invention is a trapezoidal shape The reason is that the cutting cost can be automated at the lowest cost for cutting from a film sheet or cutting from a film roll material. Also, it should be understood that the adhesive tape 38 may be a double-sided adhesive tape or a thermocompression bonding as long as the end can be joined to the frame material.

  4 is a development view arranged in the lower part of FIG. 4. The entire frame member made of a paper board is provided with a middle window 22 in the center of a middle plate 21 and an outer waist fold 23, a lower waist plate 24, and an outer leg fold 25 on both left and right sides in the longitudinal direction. The lower leg plate 26 is arranged, and in a longitudinal right-angle view, it is shown that the lower leg plate 26 is configured to have the upper waist plate 28 via the inner waist crease 27 in both upper and lower directions. When the outer waist fold 23, the lower waist plate 24, the outer leg fold 25, and the lower leg plate 26 are folded so that the folds are outside, leg legs are formed below the middle plate 21 and the upper waist plate 28 through the inner waist fold 27 is formed. 3 stand in parallel on both wings of the middle plate 21 since it is shown in FIG.

  At the left end of the developed view, the folded polyurethane film 30 after bonding the left end with the adhesive tape 38 is shown inverted to the left, but when this is joined as described at the end of [0031], a paper board material is obtained. The folded polyurethane film product 30 is positioned on the frame member made of as shown by the thin imaginary line. For this purpose, the direction of coincidence between the corners G and F of the polyurethane film shown at the left end is determined by applying two imaginary circular arcs to the right end of the middle right side of the bottom right corner of the trapezoidal film before folding and the trapezoidal film before folding. Is shown in the direction of sticking L to the right end of the middle plate at the upper right corner.

  The buffered clear packaging frame 20 shown in the exploded view of FIG. 4 is typically stored flat, but is assembled into a form suitable for use immediately prior to packaging, as shown in FIG. As a precautionary measure, the top view of the assembled shape is attached as FIG. 5: front perspective view of the buffer clear packaging frame, and the top upside down view is attached as FIG. 6: rear perspective view of the buffer clear packaging frame.

  5 and 6, the middle window 22 of the middle plate 21 of the buffer clear packaging frame 20 can be positioned at the center of the container after packaging at the time of packaging. work. 2) The upper waist plate 28, which is folded inward at a right angle at the inner waist crease 27, prevents the folded polyurethane film product 30 from bending in the longitudinal direction due to the large tension generated after packaging. 3) The lower waist plate 24 and the lower leg plate 26 prevent the distortion and torsion occurring as a whole from occurring in the longitudinal direction. It can be understood that it is functioning.

  Further, in the preceding paragraph [0022], it is stated that "this assembly is unsuitable to be transported in this shape. Therefore, an outer box for protecting the buffer clear packaging frame 20 is required." "The sheath or frame-shaped outer shell maintains the suspended state of the cushioning clear packaging frame 20 of the present invention at the time of packaging the packaged object 4, prevents the buffer clear packaging frame 20 from being distorted, and is deformed by direct external force. It is inevitable to avoid this. "

  Due to the configuration shown in FIGS. 4, 5, and 6, it is integrated with the outer box, and [0010] [0011] [0012] can solve the desired problems. In terms of strength, the lack of the left and right margin intervals in FIG. 2 is considered to be practically no problem in shock resistance if the lateral external force acceleration is set to 10 G.

  However, when the packaged product 4 is subjected to a collision with a projection such as a corner of another packaging box provided at the time of transportation after packaging from the front in FIG. It is sufficient to make the outer shell boxes 11 and 13 to be the outer boxes from a thick material, but if it is made of a transparent material and is thick, there are problems in terms of transportation and costs. In order to cope with this, the front sides of the outer shell boxes 11 and 13 may be reinforced on the front side of the buffer clear packaging frame assembly 20. One example will be described with reference to FIG. 7: a perspective view of an example of reinforcing the buffer clear packaging frame. The plate material of the packaging frame described in the first embodiment is slightly changed as follows.

(1) The upper waist plate 28 is provided with upper waist plate folds 29L on both sides in the longitudinal direction to obtain a waist plate damper at the tip thereof. This extension is held down to the width of the middle plate 21 or less. Thereby, the external impact force from the front of the outer shell can be reduced by the middle plate 21.

(2) A plate damper is provided inside the middle window 22 provided in the middle plate 21. In FIG. 7, the short damper 221 and the long damper 222 are indicated by dotted lines. Each of the paired products 4 can reduce the impact force in the peripheral direction in the middle window for each of the folded polyurethane film products 30.
