Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sealing tool for sealing the opening of a bag.

Conventional technology Conventionally, methods for resealing the opening of a bag once it has been opened include tying the opening of the bag with string or thread, tying it with a rubber band, and closing the opening of the bag with adhesive. A method of sealing with tape, a method of applying self-adhesive adhesive in advance to the folded part of the bag lid and the corresponding part of the body, a method of attaching male and female to the folded part of the bag lid and the corresponding part of the body. A method of providing a hook; A method of providing a convex strip on one side and a concave strip on the other side of the mouth of the bag; and a method of sealing the bag by fitting the convex and convex sections; A method of sealing the bag by preparing a circumscribed piece and an inscribed piece and elastically sandwiching the opening of the bag between these two long pieces (see Utility Model Publication No. 37942/1983). A method has been adopted in which a moisture-proof sealer made of plastic is used, and after the bag is opened, the mouth of the bag is pinched and the uneven parts are press-fitted (see Japanese Utility Model Publication No. 50400/1983).

Problems to be Solved by the Invention However, the method and method has problems in that it takes time and effort to seal, it also takes time and effort to reopen, and the aesthetic appearance is significantly inferior.

Although the methods described in (1) and (2) are easy to seal and reopen, they inherently lack sealing properties.

This method is advantageous in that the bag itself is equipped with a member for sealing and reopening, but it cannot be sealed unless the bag is a special bag equipped with such a member, so it cannot be used with ordinary bags. However, there is a problem in that the bag equipped with such a member is extremely expensive to manufacture.

The method described above is advantageous in that it can be used to seal various bags by preparing only two elastic long pieces.
If the elastic balance between the circumscribed piece and the inscribed piece is not set strictly, both pieces may come off and open unexpectedly, and of course it is not possible to partially release the sealed state to open the edge.

The method (2) is simple because the seal is achieved by fitting the concave and convex portions, but similarly to the method (2), it is not possible to partially release the sealed state to open the edge.

In view of these circumstances, the present invention can easily and reliably achieve the purpose of sealing, easily release the sealed state (i.e., reopen the opening), and also enable edge opening to partially release the sealed state. Furthermore, the purpose of this invention was to provide a sealing device with a beautiful design.

Means for Solving the Problems In the bag opening sealer of the present invention, an elongated member 1 having a protruding strip 1a and an elongated member 2 having a concave strip 2a that can fit into the protruding strip 1a are connected at a connecting portion. 3, the sealing tool has a configuration in which at least one of these elongated members 1 and 2 is provided with a bending part 4, and the part on the free end side of the bending part 4 is moved away from the other member. It is characterized by being configured so that it can be bent in any direction.

In this case, it is preferable to attach the hook 5 to at least one of the elongated members 1 and 2.
Further, it is preferable that the free end side end of at least one of the elongated members 1 and 2 is formed into a claw shape.

The material of the elongated members 1 and 2 is not particularly limited, but lightweight materials having appropriate rigidity and appropriate elasticity, such as plastics, hard rubber, and aluminum, are preferred.

The connecting portion 3 can be provided on one end side or the upper side of the elongated members 1 and 2.

The sealing tool of the present invention can be applied to sealing bags made of any material including plastic bags, paper bags, and cloth bags.

Next, the sealing device of the present invention will be explained in detail by giving examples.

1 is a long plastic member having a protruding strip 1a, and 2 is a plastic long member having a groove 2a. The dimensions of the protruding strip 1a of the elongated member 1 and the recessed strip 2a of the elongated member 2 are set so that they can fit into each other.

Reference numeral 3 denotes a connecting portion that connects these two elongated members 1 and 2 at one end thereof. In this example, both members 1 and 2 are integrally molded by injection molding, and the connecting portion 3 is formed as a band-shaped thin film during this molding.

4 is approximately 1/4 from the free end side end of the elongated member 1
This is a notch-shaped bending portion provided at a location, and the bending portion 4 allows the portion 1A on the free end side to be bent in a direction away from the mating member.

The free end of the elongated member 1 and the free end of the elongated member 2 are both sharpened into claw shapes.

Reference numeral 5 denotes a hanging hook attached approximately to the center of the elongated member 1.

Note that A in the figure is a bag.

Embodiment 2 FIG. 5 is a plan view showing another example of the sealing device of the present invention.

In this example, cut-shaped bent portions 4a and 4b are provided at two locations, approximately 1/4 and approximately 1/2 from the free end side of the elongated member 1.

Embodiment 3 FIG. 6 is a plan view showing still another example of the sealing device of the present invention.

In this example, there are cut-shaped bent portions 4 at two locations, approximately 1/4 from the free end side of the elongated member 1 and approximately 1/4 from the free end side of the elongated member 2.
a and 4b are provided.

Furthermore, the connecting portions 3 are provided at two locations not on one end side but on the upper portion.

Embodiment 4 FIG. 7 is a front view of another example of the sealing tool of the present invention in a sealed state.

In this example, the long members 1 and 2 are ones whose free ends are obliquely deformed,
This is convenient when the bag has only one corner opening.

Examples 5 to 7 FIGS. 8 to 10 are enlarged end views showing still another example of the sealing device of the present invention in a sealed state. Convex 1
a, this corresponds to various changes in the shape of the concave shape 2a.

Effects Next, the effects of the present invention will be explained for the case of the above embodiment.

In Example 1, when the opened bag A is sandwiched between the sealing tools in the unsealed state and both elongated members 1 and 2 are closed, the opening of the bag is sealed by the engagement of the protruding strips 1a and the grooved strips 2a. .

When you want to take out a small amount of the contents of the bag, it is not necessary to open the bag completely, so use your fingers to open the free ends of both elongated members 1 and 2 in the direction away from each other.
Portion 1A of the elongated member 1 on the free end side from the bending part 4
What is necessary is to remove the convex line 1a of the chisel from the concave line 2a of the elongated member 2. Since the free ends of both elongated members 1 and 2 are sharpened in the shape of a claw, they can be opened by placing fingers thereon, and the fitting can be easily released.

Also, if you want to reopen all the openings of the bag,
Open the claw-like sharpened portions of the free ends of both elongated members 1 and 2 in the direction away from each other with the fingers of your hands, and cross over the bent portion 4 provided on the elongated member 1 to form the convex strip 1a and the concave portion. It is sufficient to release all the fittings of the strips 2a.

The above-mentioned sealing, edge opening, and full opening can be repeated any number of times.

Incidentally, since a hook 5 for hanging is attached to approximately the center of the elongated member 1, the sealed bag can be stored by being hung on a suitable protrusion using the hook 5.

In the second embodiment, by removing the convex line 1a from the concave line 2a of the elongated member 2 up to the bent part 4a of the elongated member 1 that is closer to the free end side, the smallest edge opening can be achieved. By removing the convex line 1a from the concave line 2a of the elongated member 2 beyond the part 4a to the bent part 4b which is far from the free end side end, a medium edge opening can be achieved. When it is desired to reopen all the openings of the bag, it is sufficient to go beyond the two bent portions 4a and 4b provided on the elongated member 1 and release all the fittings of the protrusions 1a and the grooves 2a.

Similarly, in Embodiment 3, if the convex strip 1a is removed from the concave strip 2a up to the bent portion 4a provided on the elongated member 1, the smallest edge opening can be achieved; The convex strip 1a extends to the bent portion 4b.
By removing the groove 2a from the groove 2a, a medium edge opening can be achieved.

Effects of the Invention By using the sealing tool of the present invention, sealing can be performed easily and reliably, and the sealed state can be easily released (that is, reopened).

Moreover, it has the excellent advantage that it is possible to open the edge to partially release the sealed state.

Further, since the elongated members 1 and 2 are connected by the connecting portion 3, there is no chance of one member being lost.

If a hook 5 is attached to at least one of the elongated members 1 and 2, the sealed bag can be hung on a suitable protrusion and stored by the hook 5.

Furthermore, if the free end of at least one of the elongated members 1 and 2 is formed into a claw shape, the two can be opened by placing the fingers of the hand there.
Easy to unmate.

The sealing tool of the present invention can be used to seal various bags, is inexpensive to manufacture, has a beautiful design, and has high commercial value.
