Packaging containers

Technical field

The present invention relates to a packaging container for packaging an object to be packaged in a roll shape, for example, a resin film represented by a wrap film, paper, aluminum foil, or the like.

Background art

Conventionally, containers for wrapping various types of wrap films are known, but most of them are made of cardboard, and a container body for storing a wrap film wound in a roll shape and an integral part of the container body. And a lid provided in a specific manner. Generally, a cutter for cutting the wrap film drawn from the container is attached to the back of the front wall of the lid.

When using this type of container, lift the lid to expose the tip of the wrap film. Then, after pulling out the leading end of the film with a finger and pulling it out, the lid is closed and the wrapped film that has been pulled out is cut with a cutter.

After cutting the wrap film, the tip of the wrap film remaining in the container is placed between the front wall of the lid and the front wall of the container body, but the surface of the front wall of the container body is smooth. Therefore, the entire tip of the film may be in close contact with the front wall of the container body.

When the front end of the film comes into close contact with the front wall of the container body, it becomes difficult to pinch the front end of the film with a finger. In particular, it is difficult for the elderly and the visually impaired to even locate the leading edge of the film. Therefore, there is a problem that it takes time to draw out the wrap film.

Conventionally, as described in Japanese Utility Model Laid-Open Publication No. 6-511128, Japanese Patent Laid-Open Publication No. Hei 5-115690, the A proposal has been made in which a cut line is cut into the wall to form a protruding piece that protrudes outward. Shown in Figure 1 The container 1 is one of them, and the presence of the projecting piece 4 of the front wall 3 of the container main body 2 makes it possible to prevent the entire front end of the wrap film 5 from sticking to the front wall 3.

However, in the above-described conventional container, the user needs to push the protruding piece 4 outward with a finger or the like after opening, which is troublesome.

The protruding piece 4 is maintained in a protruding state using rubber 6 as shown in Fig. 1 in order to return to a flat state due to the properties of the cardboard (generally coated cardboard), which is the material of the container 1, (See Japanese Utility Model Application Laid-Open No. 6-511118). Attachment of the rubber 6 in the manufacturing process of the container 1 is troublesome and increases production cost, and it is not preferable to request the user to attach the rubber.

The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a packaging container in which a projecting piece automatically projects outward without bothering a user. .

Another object of the present invention is to make it possible to maintain the projecting state of the projecting piece.

Disclosure of the invention

In order to achieve the above object, the present invention provides a container body for storing a packaged object such as a wrap film wound in a roll shape, and a container body connected to a top edge of a rear wall of the container body so as to be rotatable. In a packaging container having a lid body, a front wall of the container body has a rectangular first wall body having one long edge connected to a bottom wall of the container body, and the other length of the first wall body. A second wall connected to the edge, the second wall being bent and adhered to the back surface of the first wall to form a projecting piece protruding outward from the first wall. A cut line that defines the protruding piece portion is formed, and both ends of the cut line extend to a folding line between the first wall and the second wall, respectively. As the shape of the cutting line, for example, there is a substantially U-shaped one.

In such a configuration, the first wall and the second wall return to a flat state with each other. The protruding part defined by the cut line extending to the folding line of both walls naturally protrudes outward and maintains that state, and the leading end of the packaged object such as a wrap film It functions as a projecting piece that makes the surface float.

Preferably, the protruding piece portion is defined at the longitudinal center of the front wall of the container body. If a protruding piece is provided, the packaged object will be gripped there, so if the protruding piece is in the center, the position where the packaged body is gripped will also be the center in the width direction of the packaged body, and one side This is because it becomes possible to suppress the occurrence of wrinkles in the above.

Further, the present invention is particularly effective when a cutter for cutting an object to be packaged is provided at the front edge of the front wall of the lid. This is because, in the case of such a container, the projecting piece is pressed by the front wall of the container main body, and the above function can prevent an operation of returning to the original position.

Further, in the case where a detachable opening piece is provided continuously to the front edge of the front wall of the lid and adhered to the front wall of the container body, the first wall portion covered by the opening piece in the closed state. At a position adjacent to the protruding piece portion, a cut portion defined by a perforation that is adhered to the opening piece and is removed together with the opening piece, and the cut portion is formed on the protruding piece portion by a perforation. It is effective to configure so as to be continuously connected via a. When the unsealing piece is cut, the cut portion is also separated from the first wall body. At that time, a force is applied to pull the protruding piece part outward, so that the protruding wall part is reliably protruded.

These and other features and advantages of the present invention will become apparent to one of ordinary skill in the art upon reading the following detailed description, with reference to the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In this specification, the terms “up” and “down” mean upper and lower in the position shown in the drawings.

2 and 3 are perspective views showing a first embodiment of a container for wrapping a wrap film according to the present invention. FIG. 2 is a view showing an open state, and FIG. 3 is a view showing a closed state. The illustrated container 10 is made from a piece of cardboard, preferably coated pole paper. Preferred coated pole paper for the container 10 is, for example, in order from the front side, a coat layer made of a transparent resin for improving printing characteristics, a first white surface layer made of a transparent bleached kraft pulp, a bleached kraft It is known to laminate a white second layer composed of pulp and deinked pulp (recycled pulp of waste paper) and a layer of waste paper composed of recycled pulp of waste paper. Such coated cardboard has the property of trying to return to a flat state even when bent.

As shown in FIG. 2, the container 10 includes a container body 16 for storing a wrap film 14 wound in a roll shape around a cylindrical paper tube 12, and a container body 16. And a cover 18 which is physically connected. The overall shape of the container 10 in the closed state has a substantially rectangular parallelepiped shape as shown in FIG. The upper part of the container body 16 is opened as an opening for pulling out the wrap film 14. The lid 18 extends continuously from the top edge of the rear wall 20 of the container main body 16, is rotatable with respect to the container main body 16, and covers the opening of the container main body 16. It is configured to be able to. On the back surface of the front wall of the lid 18 (hereinafter referred to as “lid front wall”) 22, a saw blade-shaped force cutter 24 for cutting the drawn wrap film 14 is attached. In the illustrated embodiment, the front edge of the lid front wall 22 has a V-shape, and the cutter 24 has a V-shape according to the shape. In the case of the container 10 employing such a V-shaped cutter 24, as shown in Fig. 3, the right hand is used to hold the leading end of the film, and the left thumb is applied to the center of the lid front wall 22. The most efficient way to cut the wrap film 14 is to hold the container 10 with the left hand and twist the container 10 forward, that is, in the direction of arrow A. Although not shown in FIGS. 2 and 3, before the start of use, an opening piece is continuously provided through a perforation at the leading edge of the lid front wall 22, and the container body 1 is not provided. 6 Front wall (hereinafter referred to as “main unit front wall”) 2 Adhered to the surface of 6. The opened piece seals the container 10 to prevent the blade of the cutter 24 from being exposed. In use, the opening pieces are removed.

Here, the main body front wall 26 will be described in further detail with reference to FIG. 4 in which the main body front wall 26 is developed. The main body front wall 26 is formed by a rectangular first wall 26 a having one long edge connected to the bottom wall 28 of the container body 16, and the first wall 26 a and the folding line 27. It is composed of a concatenated trapezoidal second wall 26b, and the first wall 26a is bent at right angles to the bottom wall 28, and the second wall 26b is folded along the folding line 27. And is bonded to the back surface of the first wall with an adhesive. The portion denoted by reference numeral 26c is a portion adhered to the side wall 30 of the container body 16.

A substantially U-shaped cut line 3 is provided at a central portion in the longitudinal direction of the first wall body 26 a constituting the main body front wall 26 and covered by the lid front wall 22 in the closed state. 2 is entered. More specifically, the cutting line 32 is substantially in the vertical direction (the short side of the first wall 26a). First and second cutting lines 32a, 32b extending in the direction of the hand and being spaced apart from each other by a predetermined distance, and the lower ends of these cutting lines 32a, 32b (folding line 2). (The end on the side away from 7). The third cutting line 32c extends in the lateral direction so as to purple each other. Both ends of the substantially U-shaped cut line 32, that is, the upper ends of the first and second cut lines 32a and 32b are preferably cut slightly until the fold line 27 is reached. It extends to a position where it goes into the second wall 26b beyond the wall. In the illustrated embodiment, the center of the third cutting line 32c is curved toward the folding line 27. The portion (protruding piece portion) 34 a surrounded by the cut line 32 is a protruding piece 34 that protrudes outward from another region of the main body front wall 26. For this reason, the projecting piece portion 34 a is not bonded to the second wall body 26 b, and is rotatable about the fold line 27. It is preferable that at least a part of the surface of the main body front wall 26 be provided with an adhesive layer for preventing the wrap film 14 from rewinding. The adhesive layer is formed at a portion covered by the lid front wall 22 in the closed state so that the leading end of the film can be peelably held immediately after the wrap film 14 is cut. In the container 10 of the illustrated embodiment, since the wrap film 14 is cut while holding the central portion of the lid front wall 22, the adhesive layer is formed at the central portion of the main body front wall 26, and therefore, of the projecting piece 34. It is preferably provided on the surface.

In the configuration described above, when the user uses the sealed container 10, first, the opening piece (not shown in FIGS. 2 and 3) is removed from the lid front wall 22, and the lid 1 is removed. When 8 is opened, the projecting piece portion 34a surrounded by the cut line 32 of the first wall body 26a automatically projects outward. The reason why this operation is obtained is as follows.

When the second wall 26 b is bent to the back side of the first wall 26 a along the folding line 27, the protruding piece portion 34 a and the other area of the first wall 26 a Are separated by the cut line 32, so that the projecting piece portion 34a is flush with the second wall 26b. Actually, the protruding piece portion 34a is also folded together with the other area of the first wall 26a, but the coated pole paper constituting the container 10 is resilient, so the protruding piece portion 34a is 2nd wall Try to be parallel to 26 b. For this reason, the protruding piece portion 34 a is protruded when the force in the direction of arrow B in FIG. 5 is applied, and when the restraint by the lid front wall 22 is removed, the protruding piece portion 34 a comes to function as the protruding piece 34. .

As a result, a part of the leading end of the wrap film 14 is raised from the other area of the main body front wall 26 by the projecting piece 34, and the user can easily grip the wrap film 14. It becomes possible. The third cut line 32a is curved, and an upward concave portion 36 is formed at the lower edge of the projecting piece 34. As a result, the wrap film 14 is more easily gripped.

Also, since the protruding piece 34 is disposed at the center in the longitudinal direction of the front wall 26 of the main body, the center of the wrap film 14 in the width direction is pinched, so that one side of the wrap film 14 is provided. The effect that adverse effects such as wrinkles are unlikely to occur is also obtained. After grasping the tip of the wrap film 14, pull out the desired length, close the lid 18 tightly as shown in FIG. 3, and close the lid with the thumb of the hand holding the container 10. Hold the center of the front wall 22, twist the container 10 forward, and cut the wrap film 14 with the cutter 24. At this time, the protruding piece 34 is pushed back inside the container via the lid front wall 22, but when the lid is opened, it protrudes outside again, and the tip of the wrap film 14 can be raised.

FIGS. 6, 7, 8A and 8B show a second embodiment of the present invention. The packaging container 100 according to the second embodiment has a protruding piece portion with the removal of the opening piece 50.

This is different from the first embodiment in that 34a is forcibly protruded outward. In other respects, it is substantially the same as the first embodiment, so that the same or corresponding portions are denoted by the same reference characters, and detailed description thereof will be omitted.

The container 100 according to the second embodiment is provided with a cut portion 52 cut along with the opening piece 50 on the first wall 26a. The cut portion 52 is provided at a position adjacent to the lower side of the protruding piece portion 34a and covered by the unsealing piece 50 in the sealed state. And are defined by perforations 54. The cutout 52 is connected to the protruding piece 34 a via a perforation 56. Further, the cut portion 52 is adhered to the back surface of the sealing piece 50 in a sealed state with an adhesive.

In such a configuration, when the opening piece 50 is removed to start use, the cutout portion 52 is pulled together with the opening piece 50 and is removed from the first wall 26a. At this time, since the cut portion 52 is joined to the lower edge of the protruding piece portion 34a by the perforation 56, when the cut portion 52 is removed, the protruding piece portion 34a is also shown in FIG. 8B. As a result, the protruding piece portion 34a is pulled out at the same time as the unsealing, thereby forming the protruding piece 34. In this configuration, even if the protruding piece portion 34a is caught in another area of the first wall 26a for some reason, the protruding piece portion can be securely inserted without bothering the user. There is an advantage that 34a can be pulled out.

As described above, the preferred embodiments of the present invention have been described in detail, but it is needless to say that the present invention is not limited to the above embodiments.

For example, in the above embodiment, the cutter is attached to the front wall of the lid, but the present invention is also applicable to a container in which the cutter is attached to the bottom wall of the container body.

Further, the projecting pieces are not limited to a single point, and may be provided at a plurality of places.

Further, the shape of the cut line defining the protruding piece portion is not limited to a substantially U-shape, and various shapes such as a V-shape and a W-shape can be considered.

Furthermore, the object to be packaged by the container according to the present invention may be not only a wrap film but also other resin films, paper, aluminum foil, or the like.

Industrial applicability

As described above, according to the present invention, the end portion of the packaged object such as a wrap film is lifted from the front wall of the main body due to the presence of the projecting piece, so that the tip end can be easily grasped. It can be pulled out. In particular, the position of the edge of the package It is useful for situations that are difficult to find or for the blind. In addition, the protruding piece protrudes spontaneously upon opening, and since the state is maintained, there is no need to push the protruding piece or the like, and the surface of the protruding piece is flush with the surface of other areas of the main body front wall. The harmful effect of the situation is also prevented.

When a cutter is attached to the front wall of the lid, the front wall of the lid is pressed against the front wall of the main unit together with the packaged object such as a wrap film. The present invention is particularly effective for such a type of packaging container because it has the above-described protrusion maintaining effect.
