Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shape retaining frame for a packaging bag used for subdividing products into end stores. More specifically, there are recently many small stores called so-called convenience stores, but it is our mission to handle a large number of products at this convenience store despite the small sales floor space. Therefore, we cannot store a large number of stocks, and we have a system in which we purchase stocks when they are sold. For example, in the case of jumps and rinses, we stock only a few stocks.

[0002] By the way, since each manufacturer or wholesaler purchases them in units of cases in which a large number of books are stored, goods are sent to each convenience store between the manufacturer or wholesaler and the convenience store. There will be a delivery center for subdividing and delivering. At this distribution center, products are subdivided according to the order from each convenience store, and the subdivided products are packaged for delivery to each convenience store. At that time, the bag needs to be sufficiently expanded in order to make it easy to put the product in the bag, and the present invention relates to a shape retaining frame for retaining the shape of the bag at that time.

[0003]

[Prior art]

 The shape-retaining frame 31 that has been conventionally used is made of a stepped ball, and has an upper surface and a lower surface opened, and a pair of opposed side walls 32 are folded inward from the center so that they can be folded flat (FIG. 8). ). When using, insert it into the bag 35 (usually a bag of polyethylene etc.) in a folded state, extend one of the inward folding walls to prevent the folding part from being restored, and a plastic folding collapsible box. Clip to the side wall of 33 with a clip 34.

However, in the distribution center, since it is necessary to carry out subdivision work for a large number of convenience stores by flow work, it is quite busy, and the work of attaching and detaching the clip is troublesome for the operator. In addition, the folding wall on the non-clip side is still folded inward, which has the drawback of narrowing the opening for product insertion. Furthermore, since it is made of corrugated ball, it is easily damaged and is not suitable for repeated use.

[0005]

[Problems to be solved by the device]

 The present invention has been made to eliminate the above-mentioned drawbacks of the conventional shape retaining frame, and without the trouble of using a clip as in the conventional case, the bag can be sufficiently opened by a simple operation, and the state can be maintained. An object is to provide a shape retaining frame for a packaging bag that can be maintained and has durability.

[0006]

[Means for Solving the Problems]

 The present invention is a shape-retaining frame comprising a pair of wall plates made of cardboard, plastic, etc., which are connected to each other by a pair of connecting plates that are folded inward. The member comprises a pair of members having a fixed portion that comes into surface contact with the plate and a connecting portion that extends from the fixed portion via a hinge, and a concave portion is formed at the end of the connecting portion of one of the members. Forming a fitting portion that tightly fits the recessed portion at the connection end portion of the other member of the above, coupling the connection portion end portions, and providing a hinge at any one of the end portions, The above problem is solved by a packaging bag shape retention frame formed by joining end portions of respective connection portions with a connecting member having a hinge.

[0007]

[Work]

 When the pair of wall plates are pulled apart from the folded state, the connecting plate expands, and when the fitting part is fitted in the recess, the connecting plate extends completely and becomes a flat surface to form a rectangular frame. The state is maintained until the fitting part is removed from the recess by pushing the part inward.

[0008]

【Example】

 A preferred embodiment of the present invention will be described with reference to the accompanying drawings. In the figure, 1 and 2 are wallboards made of cardboard, plastic, etc., and it is preferable that both lower corners have roundness. By doing so, when inserting into the bag 20 described later, the corner can be smoothly inserted without being caught by the bag 20. The wall plates 1 and 2 are connected to each other via connection plates 3 and 4 which are fixed on both sides of the upper end and which are folded inward. The connection plates 3 and 4 are made of plastic used for hinges such as polypropylene.

3 to 6 show in detail the structures of the members 5 and 6 forming the connection plate 3. Fixing portions 5a and 6a, each having an appropriate number of holes 7 through which fixing means such as eyelets are inserted, are formed at the ends of the members 5 and 6, and each of the fixing portions 5a and 6a has a vertical thin wall. The hinges 8 and 9 formed by slicing are formed. The connecting portions 5b and 6b extending from the fixing portions 5a and 6a are preferably narrower than the fixing portions 5a and 6a in order to reduce the weight.

A hinge 10 similar to the above is formed at an end portion of the connecting portion 5b of either one of the members (reference numeral 5 in the figure), and the hinge 10 is adjacent to the fixing portion 5a side of the hinge 10 and is connected to the connecting portion 5b. A thick portion 11 having a double thickness is formed, and a concave portion 12 having a depth corresponding to the thickness of the connecting portion 5b is formed in the thick portion 11. An insertion hole 13 such as an eyelet for connection is provided at a position closer to the end of the connecting portion 5b than the hinge 10.

At the end of the connecting portion 6 b of the other member (reference numeral 6 in the figure), a joint plate 15 having a fitting portion 14 that closely fits the concave portion 12 in a shape corresponding to the concave portion 12 is provided. It is fixed in the same way as 6b. An insertion hole 16 corresponding to the insertion hole 13 is transparently provided in the joining plate 15. By inserting an eyelet or the like through these insertion holes 13 and 16, the connecting portion 5b and the connecting portion 6b are joined. The connecting portion 5b and the connecting portion 6b form a flat surface when the fitting portion 14 is fitted in the recessed portion 12, and form a folded curved surface when the fitting portion 14 is out of the recessed portion 12.

The connecting plate 4 is also composed of members 18 and 19 having the same structure as the members 5 and 6, respectively. It is also possible to remove the portion of the member 5 beyond the hinge 10 and provide a hinge in the vicinity of the root of the fitting portion 14 instead of the hinge 10.

FIG. 7 shows another example of joining the members 5 and 6. In this embodiment, the concave portion 12 is formed at the end of one connecting portion 5b, and the fitting portion 14 is formed at the end of the other connecting portion 6b. Then, the connecting member 21 is separately provided. A hinge 22 is vertically formed in the central portion of the connecting member 21, and the tip of the connecting portion 5b is fixed to one half of the connecting member 21 by passing a small screw or the like through the small holes 23 and 24 respectively formed through the hinge. The tip of the connecting portion 6b is fixed to the other half of the connecting member 21 by passing an eyelet or the like through the holes 25 and 26 formed through the connecting portion 6b.

In the case of this embodiment, when the connecting member 21 is extended, the members 5 and 6 are aligned with each other so that the connecting plates 3 and 4 form a single plane, and the connecting member 21 has its hinge 22 portion. When it is broken in minutes, the fitting portion 14 comes off from the concave portion 12, and the connecting plates 3 and 4 form a folding curved surface.

The shape retention frame is stored in a state in which the connecting plates 3 and 4 are bent and folded at each hinge portion, and at that time, the connecting plates 3 and 4 are prevented from overlapping with each other. Set the length of 4 and the width of the wall boards 1 and 2. In use, the folded plate is inserted into the bag 20 and the wall plates 1 and 2 are pushed in opposite directions to extend the connection plates 3 and 4 (state shown in FIG. 2). Then, the fitting portion 14 is pushed with a finger to fit into the recessed portion 12. In this way, the connecting plates 3 and 4 form a plane and the shape-retaining frame becomes a quadrangle (state of FIG. 1), and the fitting portion 14 is in a tightly fitted state in the recessed portion 12 and cannot be easily removed. The shape-retaining frame keeps a square shape, and thus keeps the bag 20 wide open.

The bags 20 expanded in this way are put in, for example, two addressable boxes, transported on a large number of conveyors, and sent to the product loading operation unit. After completing the product insertion, pull out the shape retention frame and tap the center of the connecting plates 3 and 4 from the outside, the fitting part 14 comes out of the recess 12, and the connecting plates 3 and 4 fold from the hinge parts. It will be folded as it was originally. Then, it will be reused.

[0017]

[Effect of device]

 The present invention is as described above, and after the folded state is inserted into the bag, the rectangular frame can be easily configured and the state can be maintained to sufficiently expand the bag. It can be pulled out after completion of loading and easily folded and stored, which not only improves work efficiency, but also has the economical effect because it can be used repeatedly for a considerable number of times.
