Description

[Detailed description of the invention] The present invention relates to a storage device such as aluminum foil, in which a recess is provided at the tip of the lid of the storage device for storing a film-like object, and a metal film-like object cutting blade is installed in the recess. Furthermore, an insertion latching cut for inserting and latching the portion at the approximate center of the tip of the lid when the lid is closed is provided on the front surface of the casing corresponding to the approximately central position of the tip of the lid when the lid is closed. By doing so, regardless of how the membrane-like body is placed in the storage tool, the membrane-like body can be bent nearly 180 degrees when it is pulled out, pressed against the cutting blade, and cut. The body can be cut cleanly, and the cutting process is extremely smooth and easy because force is applied to pull the membranous body towards you. When pulling out the membrane, the left and right ends of the membrane are guided by the inner edge of the recess, so the pulling and stretching operation can be carried out smoothly, and when cutting, the position of the membrane in the left and right direction is at the inner edge of the recess. The cutting blade is regulated by To provide a storage device which is hard to damage the surface of a membrane-like object by a cutting blade when extending it out, makes assembly work safe and easy when assembling the storage object, and has significantly improved work efficiency. With the goal.

Conventionally, storage devices made of thin sheets of synthetic resin such as aluminum foil or polyvinylidene chloride have
As shown in the figure, a serrated blade 3 is attached to the upper end 2' of a front surface 2 of a housing 1 which is assembled by folding cardboard or the like. In addition, 4 is a side surface of the housing part 1, 5 is a bending surface from the side surface 4, 6 is a lid part, 7 is a lid surface of the lid part 6, and 8 is an insertion surface. Such a storage device stores a core body wrapped with a film-like material 9 such as aluminum foil, and when used, the tip of the film-like material 9 is pulled out and stretched out to a predetermined length. , the membrane-like material is cut by applying it to a serrated blade and bending it.

However, with such a storage device, if the membrane-like body is inserted in the way shown in Figure 2 a, for example, the membrane-like body can only be bent approximately 90 degrees when cutting the membrane-like body. Not only does cutting require a large amount of force, but the cut portion is not clean.
Furthermore, when cutting, it is necessary to apply a force to pull it in the opposite direction, and the cutting operation is not smooth and is extremely inconvenient. In addition, if the membrane is inserted as shown in Fig. 2b, the membrane can be bent nearly 180 degrees when cutting the membrane, making the cutting process relatively easy. The lid must be opened extremely wide when the shaped body is pulled out, which makes the work before cutting that much more troublesome.
In addition, the direction in which the force is applied must be such that it is pulled in the opposite direction, and the cutting operation is not smooth.
This is extremely inconvenient. Moreover, if it is inserted as shown in FIG. 2b, the rotational movement of the membrane-like body, especially in the case of a synthetic resin thin film sheet, will not be smooth and it will be difficult to pull out the membrane-like body.

Furthermore, when the storage device is stored, the lid surface always comes into contact with the tip of the serrated blade, so there is a risk that the serrated blade will fall sideways or be damaged. In addition, if you insert the insertion surface of the lid into the housing and grasp it when taking out stored items, the serrated blade will protrude from the lid surface, so the serrated blade may cause injury to your hands. be.

Further, when the membrane-like body is pulled out from the storage tool, the surface of the membrane-like body may be rubbed by the saw blade, and the membrane-like body may be unnecessarily damaged.

In addition, when folding and assembling the cardboard etc. with the serrated blade attached, the serrated blade gets in the way when assembling the casing, and the efficiency of the assembly process is poor. You may get injured and it is not safe. Furthermore, if the serrated blade is attached after assembly, the efficiency of the attachment work is extremely poor.

The present invention eliminates the above-mentioned drawbacks, and embodiments thereof will be described below.

FIG. 3 and FIG. 4 are explanatory diagrams of an expanded state and an assembled state of the embodiment of the storage device according to the present invention.

In the figure, 10 is a casing made by folding cardboard or the like, and 11 is a lid part connected to the casing 10 at one end. Reference numeral 12 denotes a front surface constituting the casing 10, 13 a side surface of the casing 10, and 14 a bent surface from the side surface 13. Reference numeral 15 is a lid surface constituting the lid body portion 11, and 16 is an insertion surface that is bent at the tip of the lid surface 15.

Reference numeral 17 denotes a metal serrated blade, which is attached to the entire recess at the tip of the insertion surface 16, or only to the right or left end of the recess at the tip, or only to the right and left ends of the recess at the tip. There is.

Reference numeral 18 denotes a substantially convex arc-shaped cut formed approximately in the center from the left and right sides of the front surface of the casing, and is used for inserting and latching the tip of the insertion surface of the lid.

Note that 19 is a film-like body such as aluminum foil wrapped around a core body, and is housed in the housing.

The storage tool constructed as described above is made by first folding a piece of cardboard formed into a predetermined shape with a serrated blade attached to a predetermined position along each fold, and then joining the predetermined parts with adhesive. In addition to configuring the casing section, the casing section also constitutes the lid section. During this assembly work, the storage tool of the present invention has a serrated blade attached to the tip of the lid, so the serrated blade does not get in the way at all when, for example, gluing the sides and assembling the casing. During these operations, the serrated blade does not injure the hands, etc., making the operations safer and improving work efficiency. In addition, since the serrated blade can be easily attached to the tip of the lid even after the storage device is assembled, the order of the work steps can be changed as necessary, making the work proceed more smoothly. It also becomes.

And when using the assembled storage equipment,
Pull out one end of the stored aluminum foil, etc., and after it reaches a predetermined length, bend the aluminum foil, etc. by about 180 degrees with a saw blade, and cut it while applying force. In this way, the film-like material such as aluminum foil can be folded back approximately 180 degrees when cutting, so the force required to cut it is reduced.
In addition, since the folds are neatly formed, the cutting line will also be clean. Also, when applying force by pulling on the membranous body, the hand that is gripping a part of the membranous body does not move away that much because it is pulled toward the front, and the way to apply force is difficult. etc., the operation is good and the cutting operation is extremely easy. Moreover, these features are the same regardless of how the membrane-like body is inserted, that is, even if it is stored as shown in Figure 2 a or b, so consider how the membrane-like body is inserted. There is no need for it, and it becomes more convenient. When the membrane-like body is placed as shown in Figure 2 a, it is convenient because the movement of the membrane-like body within the container is extremely smooth. Not at all.

Also, the serrated blade is attached to the tip of the insertion surface of the lid, so if you insert the insertion surface into the cut, the serrated blade will stick out no matter where you grasp the storage tool. It is much safer. Furthermore, since there is no member that comes into contact with the tip of the serrated blade, there is no damage such as the serrated blade falling sideways.
Furthermore, by adjusting the degree of opening of the lid, the length of the membrane-like body can be adjusted even if the degree of extension of the membrane-like body is constant, so that the cut membrane-like body is not wasted.

In addition, since the cut for latching the insertion surface is formed approximately in the center from the left and right sides of the front of the casing, the work of inserting and latching the insertion surface is easy when holding the central portion, which makes it easy to hold the storage device. can be done with just one touch, making the process extremely convenient. On the other hand, if cuts for insertion and latching are formed only on the left and right ends of the front surface, for example, when inserting and latching work on the insertion surface, the insertion and latching work cannot be done without holding the storage tool again and using both hands. This is not possible and would be extremely inconvenient. In particular, when the membranous cutting blade is provided at the tip of the insertion surface, if cuts for hooking the insertion surface are formed at positions corresponding to the left and right ends of the insertion surface, the insertion surface can be inserted into these cuts. When inserting and locking the tip of the face, the left and right tips of the insertion face, that is, the left and right ends of the membrane cutting blade, become bent, and the strength of this part weakens, resulting in Aluminum foil, etc., where the cutting start is particularly important, cannot be cut well, and a clean cut surface cannot be obtained. In contrast, in this embodiment, the cut for inserting and locking the insertion surface is formed almost in the center, so there is no such drawback at all, and the membrane cutting blade near the center is slightly cut. Even if the device is bent, the strength of the user's back is reinforced by the strength of the hand holding the storage device, and aluminum foil, etc., can be easily cut, and the cut surface is clean.

In addition, since a membrane-like cutting blade is provided in the recess formed at the tip of the insertion surface, when pulling out the aluminum foil, etc., the aluminum foil, etc. is guided by the inner edge of the recess, so that it can be cut well. Become.

In addition, when a cutting blade such as a serrated blade is provided over the entire tip of the insertion surface, the insertion surface becomes less likely to bend laterally, and the cutting operation becomes easier. In addition, if the cutting blade is only provided at the end of the tip, as long as the beginning of the cutting can be done, the rest can be easily cut without the cutting blade, which means less material is required and the cost is lower. can.

As described above, the storage device according to the present invention includes a recess provided at the tip of the lid body of the storage body that stores the membrane-like body,
A metal film-like cutting blade is provided in the recess, and an insertion/latching cut is provided at approximately the center of the tip of the lid when the lid is closed. It is provided on the front of the housing corresponding to the position, so
The membrane-like cutting blade does not get in the way at all when assembling the storage equipment, and there is no chance of injuring your hands, etc., which is much safer, and you don't have to be extra careful during the work, which makes the work much easier. Efficiency is improved, and when cutting a membrane-like object, almost no membrane-like object can be cut.
Since it can be folded back 180 degrees, it can be folded neatly, and furthermore, when cutting, the position of the membrane in the left-right direction is restricted by the inner end of the recess, so there is no possibility of the membrane becoming misaligned in the left-right direction. Therefore, the synergistic combination of these factors results in a cleaner cut line, and since the force applied to the membrane is pulled toward the front, the cutting operation is smoother. In addition, it can be cut with a small force, and since the left and right ends of the membrane are guided by the inner edges of the recess when pulling out the membrane, the membrane can be stretched diagonally. There is no such thing, and this guide action allows the membrane-like body to be pulled out smoothly, and furthermore, there is no chance of injury from the membrane-like body cutting blade when gripping the storage tool. Also, when pulling out the membrane, the surface of the membrane is not damaged, and the membrane cutting blade is less likely to be damaged, and the part inserted into the insertion and locking cut is made of metal. If a cutting blade is provided, this part is reinforced to have high mechanical strength, so the insertion operation can be performed smoothly, and this insertion latching operation is performed because the insertion latching cut is provided at the center position. In addition, if the insertion and locking cuts are provided at the left and right end positions, a bending phenomenon occurs at the left and right ends of the membrane-like cutting blade at the tip when inserting and locking. For this reason, the strength of the waist in this part gradually weakens and the cutting initiation action cannot be performed properly.However, with the structure of the present invention, such drawbacks will not occur, and moreover, the metal membrane-like body Inserting the cutting blade into the insertion and locking notch provides greater safety.In particular, since there is a part of the lid at both ends of the metal membrane cutting blade, it is easy to cut metal membranes. It does not get caught on the edge of the blade, making it extremely safe.
