As shown in Japanese Patent No. 35957, it consists of a mount, a holding piece, and a skin pack film, and the object to be packaged is fixed on the mount by the holding piece and subjected to skin pack packaging.

The holding piece is used to fix the packaged item to the mount, and in the simplest case, a simple coated wire or the like is used.

[Problems to be Solved by the Invention] In the above-mentioned conventional skin pack packaging apparatus, the object to be packaged is not fixed to the mount in a good manner, and even when skin pack packaging is performed, the object to be packaged protrudes from the specified position. There were problems that needed to be resolved, such as frequent defects, low quality stability, and poor workability.

This invention was made in order to solve such conventional problems, and it is possible to fix the packaged items to the mount in a good manner and prevent the packaged items from protruding from the specified position even when skin pack packaging is applied. The purpose is to obtain an inexpensive skin pack packaging device.

[Means for Solving the Problems] A skin pack packaging device according to the present invention includes: a mount formed by bending from the inside to the outside and having fixing pads having holding portions for fixing both ends of the packaged object; It consists of a film that covers the packaged item fixed on the mount,
The structure is such that at least one of the fixing pad or the holding portion of the fixing pad applies a load to the packaged item to maintain the packaged item in a fixed state.

[Function] In this invention, at least one of the fixing pad or the holding portion of the fixing pad can apply a load to the packaged item to maintain the packaged item in a fixed state, without requiring a separate holding piece. , it becomes possible to stably fix the item to be packaged at a designated position on the mount and carry out skin-back packaging.

[Example code] Each of the drawings shows an embodiment of the present invention.

First, the embodiment shown in Figs. 1 to 3 will be explained. This skin pack packaging device is formed by bending from the inside to the outside, and has a pair of holding parts 1 that fix both ends of the packaged object W. A mount 3 on which a fixing pad 2 is formed;
It consists of a skin pack film 4 that covers the packaged object W fixed on this mount 3. In this example, the article to be packaged W is a pipe-shaped article having small diameter portions W1 at both ends. The fixing pad 2 is formed into a rectangular shape having a planar area on the projected plane of the end surface of the object W to be packaged, and is in a planar form as it is cut out on the mount 3 until it is used for packaging. It is bent from the inside to the outside and stands up against the mount 3. The holding portion 1 is formed as a punched hole into which the small diameter portion W1 is fitted and held, and is open to one side of the fixing pad 2 through a lateral introduction portion 5.

The fixing pad 2 is used to apply a load to the object W to be packaged.
A structure is provided to keep it fixed. this is,
Specifically, the bent ruled line 6 is set so that a return elasticity is generated by bending and raising, and the return elasticity of the pair of fixing pads 2 acts inwardly toward each other, and becomes a force that clamps the packaged object W.

In the above configuration, the fixing pad 2 is elastically deformed and raised by a bending operation along the ruled line 6, and the introduction part 5 is inserted into each holding part 1.
The small diameter portion W1 of the object to be packaged W is held from the side, and the object to be packaged W is fixed to the fixing pad 2 at both ends. The object to be packaged W in this state is in a pinched state where a load is applied by the return elasticity of the fixing pads 2 acting inwardly toward each other. When the skin pack film 4 is applied to the packaged object W fixed to the mount 3, skin pack packaging is completed.

During skin-back packaging, the item W to be packaged is fixed and maintained at a specified position between the fixing pads 2, so that
4. Packaging defects such as the product W protruding from the specified position do not occur, the quality is highly stable, and the workability is good.
The figure shows an example in which the introduction part 5 following the holding part 1 is obliquely oval-shaped with a downward slope to make it easier to attach the small diameter part W1 to the holding part 1. Fig. 6 shows an example in which the introduction part 5 following the holding part 1 is directed upward and the shape of the introduction part 5 is widened towards the end, and Fig. 7 shows an embodiment in which the introduction part 5 is not opened. Examples are shown below. In any of these cases, the fixing pad 2 has the effect of holding the object W to be packaged, and the same effect as in the above-mentioned embodiment can be obtained.

Each figure from FIG. 8 to FIG. 13 shows different embodiments of the holding part 1 in the fixing pad 2. It is characterized in that the holding part 1 is also provided with a structure for maintaining the state. That is, the holding part 1 shown in FIGS. 8 and 9 is configured as a punched hole having a smaller diameter than the small diameter portion W1 of the object to be packaged W, and a cut groove 7 is formed from the eccentric position of this punched hole to the upper side. There is. One of the upper parts of the fixed pad 2 separated by the cut groove 7 has a movable ruled line 8 at its base.
is formed. Small diameter part W of the packaged object W to the holding part 1
Holding of I is performed by bending one side of the upper part of the fixed pad 2 at the movable ruled line 8, and pushing the small diameter part W1 into the holding part 1 while widening the cut edge 7 part. Since the holding portion 1 is smaller in size than the object to be held, a clamping force is applied to the object to be held after the bending force is released. In other words, the packaged object W is fixed to the mount 3 by both the return elasticity of the fixing pad 2 and the return elasticity of the holding part 1.
The stability of the fixed state is higher than that of the first embodiment.

In addition, the one shown in FIG. 10 has a pressing piece 9 that acts on the outer periphery of the small diameter part W1 with a return elastic force on the edge of the hole of the hollow hole serving as the holding part 1, so that the small diameter part W1 inserted into the holding part 1 is It is configured to be held by a pressing piece 9. Furthermore, the first
The holding part 1 shown in Fig. 1 is configured with a plurality of radial notches 10 without opening the holding part 1, and the function similar to that of the pressing piece 9 shown in Fig. 10 is to press the small diameter part W1. In addition to this, the outer periphery of the small diameter portion Wl is covered, thereby providing a protective function. Furthermore, the first
2 and 13 eliminate the movable ruled line 8 of the embodiment shown in FIGS. 8 and 9, and twist and displace one side of the upper part of the fixed pad 2 separated by the cut groove 7. Thus, the holding portion 1 is made to hold the small diameter portion Wl.

In addition, as shown in FIGS. 14 and 15, in any of the above embodiments, when a packaging form is adopted in which a plurality of items W to be packaged are lined up and packaged together, there is a spacer in the vicinity of the fixing pad 2 to separate the items W to be packaged. It is preferable to provide the separation pad 11 by cutting and raising it.

[Effects of the Invention] As is clear from the above description of the embodiments, according to the present invention, at least one of the fixing pad or the holding portion of the fixing pad applies a load to the packaged item to keep the packaged item in a fixed state. The packaged items can be stably fixed at the specified position on the mount without the need for a separate holding piece, and the packaged items will not protrude from the specified position even if skin pack packaging is applied. A skin pack packaging device with high quality and low cost can be obtained.
