Description

  The present invention relates to a package for a bar-shaped solid article, and more specifically to an improvement in the opening structure of the package.

  The package has a wide variety of forms. For example, as a package for a stick-shaped article such as a writing instrument, a pillow package bag in which pillow packaging is performed may be used. In order to open such a pillow packaging body without using a tool such as scissors, there is one in which a cut (also referred to as a “notch”) is provided in at least one end seal portion at both ends of the pillow packaging bag. This cut has various shapes such as a straight line and a V shape.

  However, the opening structure of the pillow packaging bag using these cuts has the following problems. First, the size and shape of the cut are small, and it is not easy to find the opening position. Also, when opening the pillow packaging bag by these cuts, if the item to be packaged is vertically long like a rod-shaped article, there are few parts to be picked when opening by opening the seal part of either end with both fingers. Work is not easy. In addition, in some cases, the film forming the package is torn in an unintended direction, and the knob portion is cut off during the opening process, so that it is not possible to obtain a sufficient opening for taking out the contents. .

As one method for easily opening the horizontal pillow package other than the configuration in which the cut is provided, there is a method in which perforations are provided in parallel with the seal portions at both ends of the packaging bag. For example, in the invention disclosed in Patent Document 1, a perforation is provided in a part of the laminated film so that the package can be easily opened.

  However, merely providing a perforation for opening on the pillow package requires a certain amount of force when opening, and there is a problem that it cannot be opened easily. In particular, in the case of a rod-shaped article, the opening operability is poor because the portion for gripping the film is small.

  This invention solves the subject mentioned above, The objective is to provide the package body which can perform an opening operation | work easily and with small force.

  In order to achieve the above object, a packaging body according to the present invention is a packaging body formed by surrounding a packaged article made of a rod-shaped solid article with a packaging film, and one end in the longitudinal direction of the packaging body On the side, a perforation for opening a film extending in a direction intersecting with the longitudinal direction is formed, and the packaging film is positioned at an end of the package by pinching the film portion on the one end side outside the perforation. The perforation was set so as to be located outside the packaged item when it was contacted.

  According to this invention, since the perforation is provided at a predetermined position on the one end side of the package, the package and the one end of the package on the side on which the perforation is formed are gripped and formed by the packaging film. By crushing the space, the film portion located on the side of the packaging film out of the packaging film can be moved further (movement in the direction in which the space of the packaging film is crushed) when the packaging film contacts the packaging object. The film part including the perforation on the tip side from the contacted part is crushed. Thereby, since the force of the direction torn to a perforation is added, a perforation is fractured | ruptured and a package body is opened. Unpacking can be done with a simple process by crushing the tip of the package. In addition, since the entire tip portion can be gripped, the gripping area can be made relatively large as compared with those provided with notches.

  On the other hand, the package can be opened by utilizing the leverage of the article to be packaged by bending the article to be perforated. Therefore, the package can be easily opened with a small force.

  Moreover, it is good to form so that the both ends of the said perforation may face the said to-be-packaged object side. If it does in this way, after a perforation is cut | disconnected and opened, a film will be torn in the direction which the both ends of the perforation face, and it can open a package body largely.

  Further, the perforation may be formed over a half circumference of the package. In this way, it is possible to make a large opening part of the package body by perforation, and when the package film is torn after that, the package film can be separated and divided from half to both sides, and the package body is greatly opened. be able to.

  Furthermore, the direction in which the packaging film is easily torn is preferably set in the longitudinal direction. If it does in this way, a film will be torn in the direction which the both ends of the perforation face, and a package can be opened largely.

  Also. The package may be a pillow package. Of course, other packaging forms are possible. In addition, when it is set as a pillow package body, it can open large by tearing a film along a center seal | sticker site | part.

  In the present invention, the opening position can be easily performed with a small force by devising the setting position of the perforation.

  FIG. 1 shows a preferred embodiment of the present invention. Since the pillow package of this embodiment is for storing the rod-shaped article 1 as an article to be packaged, it is elongated as a whole. The rod-shaped article 1 includes, for example, a writing instrument such as a pen, a stationery instrument such as a stick type glue, and a cosmetic instrument such as a lipstick. Each of the rod-shaped articles has a certain degree of hardness (a degree that is not deformed or crushed by the force of a human finger or the like).

  The pillow package 10 has a configuration in which a bar-shaped article 1 is surrounded by a packaging film 2 and a polymerized portion of the packaging film 2 is sealed and closed. As for the seal part, the end seal part 3 is formed at both longitudinal ends of the pillow package 10, and the center seal part 4 extending along the longitudinal direction is formed so as to connect the pair of end seal parts. Since the basic structure of the pillow package 10 is general, a detailed description thereof is omitted. Moreover, the packaging film 2 of this embodiment is set so that it may be easily torn in the longitudinal direction of the pillow package 10.

  In the present embodiment, the perforation 5 is formed in the film portion of the packaging film 2 located between one end seal portion 3 (upper side in the figure) and the rod-shaped article 1. The perforation 5 is provided on the surface side (half of the entire circumference) where the center seal part 4 of the pillow package 10 is not formed. The perforation 5 is formed in a straight line and extends in a direction perpendicular to the longitudinal direction of the pillow package 10.

  In order to open the pillow package 10 according to the present invention, the pillow package 10 can be opened easily and with a small force through the procedure shown in FIG. Fig.2 (a) is the figure which looked at the unopened pillow package body 10 shown to Fig.1 (a) from the side. In this state, the perforation 5 is formed up to half. In FIG. 2, only one hand of the opening operator is shown, but the main body (bar-shaped article 1) of the pillow package 10 is gripped by the opposite hand (not shown).

  As shown in FIG. 2B, the end on the side where the perforation 5 is formed is pinched with one hand (FIG. 2B). As shown in FIGS. 2 (a) and 2 (b), the perforation 5 is set so as to be located near the rod-shaped article 1 and, as shown in FIG. 2 (b), with one hand. When the packaging film 2 comes into contact with the end of the bar-shaped article 1 by pinching the end on the side where the perforation 5 is formed, the perforation 5 is located near the outside of the bar-shaped article 1 (on the end seal part 3 side). It is set to be.

  Therefore, when the distance between both fingers is narrowed so that the fingers are further crushed from the state of being pinched by the fingers of one hand, the packaging film 2 is located on the rod-shaped article 1 side of the packaging film 2. Further movement (movement in the direction in which the space of the cylindrical packaging film is crushed) is restricted, and includes a perforation 5 on the tip side (end seal part 3 side) from the contacted part. The film part is crushed. Thereby, since the force of the direction torn in the perforation 5 is added, as shown in FIG.2 (c), the perforation 5 is fractured | ruptured and the pillow package 10 is opened.

  When the end seal part 3 side is further moved away from the rod-shaped article 1 in a state where the entire perforation 5 is broken by the above processing, as shown in FIGS. 1 (b) and 2 (d), The packaging film 2 is torn along the longitudinal direction from the vicinity of both ends of the perforation 5, and the pillow package 10 is greatly opened. Thereby, the rod-shaped article 1 can be easily taken out. In this way, the packaging film 2 is torn along the longitudinal direction of the pillow package 10 from the vicinity of both ends of the perforation 5 while using a film material having the property of being easily torn in one direction as the packaging film 2. This is because the direction to be easily torn is set to be the longitudinal direction of the pillow package 10.

There are a plurality of (two directions) directions that are easy to tear, and the longitudinal direction of the pillow package body 10 and the direction orthogonal to the longitudinal direction of the pillow package body 10 are both easy to tear, When set in the orthogonal direction, the packaging film is torn along the extending direction of the perforation 5, so that it is cut as it is over the entire circumference of the pillow packaging body 10, but usually the film strength of the center seal part 4 is increased. Therefore, the center seal part 4 is not cut, and then the packaging film is torn along the longitudinal direction of the pillow package 10 along the center seal part 4, and the pillow package is greatly opened, Even the elongated rod-shaped article 1 can be easily taken out.

FIG. 3 shows a modification of the perforation. In either case, both ends of the perforation 5 are directed to the rod-shaped article 1 side (longitudinal direction. Therefore, it is guided that the perforation starts to be cut in the longitudinal direction of the pillow package 10. Also, as shown in FIG. By turning both ends of the perforation 5 to the end seal part 3 side, the perforation direction of the packaging film is reliably cut from the end portion of the perforation toward the longitudinal direction of the pillow packaging body 10 without being cut all around. be able to.

It is a perspective view of the package which shows one embodiment of this invention. It is a figure explaining an effect | action. It is a figure which shows a modification.
