Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a powder-tight sealed container that mainly contains powder such as detergent, salt and sugar, and granular objects, and particularly has a substantially rectangular shape. The present invention relates to a seal lid which covers the opening of the container body and reseal the same.

[Prior Art and its Problems] Conventionally, many rectangular containers for storing powder have been proposed. However, in general, in such a container, a seal lid is hermetically attached to the opening of the upper surface of the container to prevent powder. It is sealed so that it will not be broken. The seal lid has a structure in which a lid made separately from the container body is fitted on the outer periphery of the opening of the container body to seal it, and a hinge lid is integrally attached to the container body to thereby Some have a structure in which the opening of the container is opened and closed. The former is, for example, a structure commonly found in containers commonly called Tappaware (trademark), and is known to have high sealing performance. On the other hand, however, the lid and container body are made of a soft material. However, the opening is easily deformed, which makes opening and closing difficult. In addition, since the lid and the container body are separate bodies, there is a problem that the lid easily dissipates.

On the other hand, in the latter, since the container body and the lid are integrated, there is no problem of dissipation. However, this type cannot retain a high degree of hermeticity as compared with the former.
Further, since a hinge is provided between the container body and the lid, it is necessary to perform special processing on each of the container body and the lid. For example, various processes such as forming a botch for attaching a hinge lid on one side and opening a hole for inserting the botch on the other side to attach the lid are required. Therefore, there is a drawback in that the molding process is troublesome when the container main body and the lid are molded, and the mold cost is high because the mold is difficult to manufacture.
Not only that, the main body and the lid must be integrally connected in advance, and it is not possible to easily attach the lid to the opening of the container main body on the packaging line of the contained items to complete the product. There was also a defect above. Furthermore, in the former and the latter, regarding the so-called virgin property of the container whether or not the container has already been opened once, a label or a seal is separately attached between the container and the lid. We couldn't guarantee it unless we took the steps.

[Object of the Invention] Here, the inventor of the present invention opened the container main body on the packaging line of the contents in the same manner as a normal seal cover without performing special processing on the container main body with a seal cover having a hinge function. Can be attached from above, and the container opening can be securely sealed to ensure the virginity of the stored contents product. Furthermore, when the lid is opened, the tear-off strip of the lid is torn off in the circumferential direction. , The lid is divided up and down from the middle part,
The present invention proposes a hinge lid container that is resealable and has a high hermeticity even when resealing, a part of which is connected to the container body via a hinge.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the seal lid of the present invention is a plastic drop lid attached to hermetically seal the opening (2) of the container body. Of the sealing member (3) fitted inside the side wall forming the opening, the rising portion (4a) standing up on the entire circumference of the sealing member, the rim (5) provided at the upper end of the rising portion, and the rim of the rim. It is surrounded by the engaging edge (6) extending downward all around the outside, the rising portion (4a), the rim (5) and the engaging edge (6), and the opening edge (2b) of the container body. Groove (5a) capable of holding a groove, a hinge part (7) formed in a part of the engaging edge, and a cut-off strip (8) formed so as to be cut in the lid circumferential direction excluding the hinge part. Further, from the lower part of the rising part (4a) to the engaging edge (6) A protrusion (4b) that is formed so as to protrude toward and that can press the side wall inner surface that forms the opening of the container main body to the outside, and at the position of the lower portion of the engaging edge that faces the protrusion, The present invention is characterized in that a ring-shaped remaining portion (6b) formed by a portion remaining after stripping off the cut-off strip (8) is provided.

Further, when the above-mentioned seal lid is attached to the top opening of a container for containing articles such as powder and granular articles which need to be sealed, it is possible to obtain a container having extremely high hermeticity even when resealing after opening. It is a thing.

[Embodiment] The present invention will be described in detail with reference to the drawings.

The drawings show one embodiment of the present invention. FIG. 1 is a perspective view of a seal lid and a container body closed by the seal lid, and FIG. 2 is a perspective view showing only an upper portion of the container body closed by the seal lid. FIG. 3 is a perspective view showing a state in which a part of the lid is cut off, FIG. 4 is a cross-sectional view taken along line 4-4 of FIG. 2, and FIG. 5 is a perspective view of the upper part of the container main body showing an opened state. FIG. 6 is a partial cross-sectional view of the upper portion of the container body showing the resealed state.

In the drawings, reference numeral 1 indicates a container body molded using a thermoplastic resin such as polypropylene resin, and the top opening 2 thereof is formed in a rectangular shape as an example, but the shape is not limited to the rectangular shape shown in the drawing, but a square shape. Other shapes exist. Reference numeral 2a is a rib formed on the outer peripheral surface of the opening so as to project in the horizontal direction, and one rib may be provided continuously over the entire circumference of the opening 2, or as shown in FIG. Two or more may be intermittently provided.

Reference numeral 3 is a lid for covering the opening surface of the container body, which is made of a molded product of thermoplastic resin as described above, but preferably polyethylene resin can be used. The lid 3 corresponds to the shape of the opening 2 of the main body, covers the opening, and is formed in a size that can be fitted into the inner side wall forming the opening, and the entire circumference of the closing member. A rim 5 provided integrally with the rim 5 and an engaging edge 6 extending downwardly on the outer periphery of the rim are provided.

The plan-view shape of the blocking member 4 is formed in a rectangular shape as an example so as to match the top opening 2 of the main body. By the way, the sealing member shown in the figure has a U-shaped cross section as shown in FIG. When the closure member closes the top opening 2 of the main body, it is pushed into the inside of the side wall of the opening to raise the closure member 4a.
The projecting portion 4b formed on the inner surface of the opening 2 is configured to come into contact with and closely contact with the inner surface of the side wall of the opening 2.

The rim 5 provided around the entire circumference of the sealing member is provided with a groove 5a which can be firmly fitted into the top opening edge 2b of the main body. Then, an endless engagement edge 6 is extended downward on the outer periphery of the rim. The length H of the engaging edge is set to be larger than the height h from the top end of the opening 2 to the lower side of the protruding rib 2a. Then, a concave portion 6a that fits with and engages with the rib 2a is formed inside the hem of the engaging edge.

By the way, in the present invention, on the back side of the lid, the hinge portion 7 which can be bent in the vertical direction is integrally formed at the intermediate portion of the engaging edge located between the lower side of the rim 5 and the concave portion 6a, and A cut-off strip 8 is provided on the entire circumference of an intermediate portion of the engaging edge excluding the hinge portion, and the protruding portion is provided below the engaging edge.
It is indispensable to provide a ring-shaped remaining portion 6b formed by the portion remaining after stripping off the cut-off strip at a position facing 4b, so that the hinge portion 7 can be bent easily as shown in FIG. In addition, the engaging edge is locally thinned to be a thin portion, and upper and lower score lines 8a are formed on the boundary between the cut-off band 8 and the engaging edge so as to be divided. In addition,
In providing the cut-off strip 8, two hinge strips 7 may be provided intermittently on both sides thereof, as shown in FIG. 3, or one continuous strip may be provided as shown in FIG. May be. By the way, reference numeral 8b is a gripping piece for cutting formed at the end of the strip.

The reference numeral 9 is an opening knob that is partitioned and formed on the engagement edge 6 on the front side of the lid. In providing this knob, it is provided at a position symmetrical to the hinge 7, and is formed integrally with the rim along the score line or the cut line corresponding thereto that divides the cutout band.

[Operation] When the seal lid 3 of the present invention configured as described above is attached to the container body and sealed so as not to leak powder, the container body is filled with the contents on the packaging line. The top opening 2 is covered with a sealing member 4 from above, and the top opening edge 2b of the main body is fitted into a groove 5a provided inside the rim on the periphery thereof. At that time, the ribs 2a provided on the outer periphery of the opening of the main body are press-fitted into the recessed portions 6a provided on the inner side of the hem of the engaging edge 6 provided on the outer periphery of the rim to engage the two, and the rising 4a of the closing member is opened. Push it inside the side wall of the projection to project inside the opening
Stick 4b together. That is, when the blocking member 4 is attached so as to be dropped inside the opening 2 of the container body, the blocking member 4
The projecting portion 4b provided on the rising portion 4a of the container bites into the inner surface of the side wall of the container body and presses it so as to open it outward. on the other hand,
Since the ring-shaped remaining portion 6b located below the engaging edge 6 and facing the protrusion 4b resists the opening of the side wall, the seal lid is firmly engaged with the container body and is prevented from coming off. , And a high degree of sealing is maintained,
The so-called virgin nature of the contents is guaranteed. On the other hand, in order to open the container body 1 closed by the seal lid 3, first, as shown in FIG. 3, the clipping gripping piece 8b provided on a part of the engaging edge 6 is pulled to bring the score line 8a to the score line 8a. Cutout strip 8 along
Is cut from the engaging edge. By doing so, almost the entire circumference of the engagement edge 6 is cut off, except for the hinge 7 provided on the back side of the lid. As a result, the hem of the engaging edge remains in a ring shape while being fixed to the outer periphery of the container body via the rib 2a and the recessed portion 6a, and the sealing member 4 is hinged to a part of the ring remaining portion 6b. 7 are connected in series. And this blocking member 4
Can be easily pushed up and opened via the opening tab (Fig. 5). Since this closing member becomes a hinge lid that can be repeatedly opened and closed by the hinge, there is no dissipation, and even when resealing, the protruding portion 4b bites into the inner surface of the side wall of the container body and presses it outward, the same as before opening. It can be used as a simple sealed container (Fig. 6). By the way,
When the lid of the present invention is pushed up and opened as shown by the arrow in FIG. 6, the rising portion 6a on the opened side is pushed up while curving slightly inward with the protrusion 4b as a fulcrum. After that, even when the lid 3 is resealed, the middle portion of the engagement edge 6 remains cut off, so that it is possible to visually confirm that the container is once opened.

[Effects of the Invention] As described in detail above, the present invention provides a cover with a hinge function, which is made separately from the container body, and does not have a special hinge process on the container body side. Like the lid, it can be easily attached to the opening of the container body on the packaging line for the contents. In addition, the seal lid of the present invention,
Since the sealing member is installed so as to be dropped inside the opening of the container body, the protrusion provided at the rising portion of the sealing member bites into the inner surface of the side wall of the container body and presses it to open outward, while facing the protrusion. Since the ring-shaped remaining portion located at the position to resist the opening of the side wall prevents the seal lid from tightly engaging with the container body and separating from the body, a high degree of sealing is maintained. Also, opening is easy because it slightly bends inward with the protruding portion of the rising portion as a fulcrum, and at the time of resealing, the protruding portion bites into the inner surface of the side wall of the container body and presses it outward, so It has the effect of having the same sealing performance.
