Description

container

The present invention relates to a container, and more particularly, to a container that can be closed again for a while after being once closed (re-sealed easily).

There is a container whose top opening is closed with a lid. In some of such containers, it is desired that the lid material that has been peeled off halfway be returned to the original state (typically, the opening portion is resealed) temporarily. For example, with instant noodles in a cup, the lid material is peeled off halfway, and hot water is poured into the cup through the cup opening that is half open. The lid material peeled off about half is used to easily reseal the cup opening, and is completely peeled off after a predetermined time.

[Patent Document 1] describes that a tab having cut notches is provided at two opposing positions on the peripheral edge of a lid material, and the cup notch is sandwiched between the cut notches of the tab to reseal the cup.

JP 2001-180737 A

In the cup described in Patent Document 1, the tab formed on the peripheral portion of the lid material is also used as a knob when the lid material is peeled off. Since the notch is formed in the tab, the tab may be torn from the lid material along the notch when the lid material is peeled off.

The purpose of this invention is to provide a container having a novel resealing structure of the opening part.

The container according to the first aspect of the invention is adhered to a tubular body portion having a curl portion formed at an upper edge peripheral edge thereof, a bottom portion provided at a lower end of the body portion so as to close a lower surface thereof, and the curl portion. An inner container provided with a lid member for closing an upper surface of the body, and an outer cylinder covered and fixed to the body so as to form an insulating space between the outer side of the body and the lid, It is a so-called double container (double container). In the container according to the first aspect of the present invention, a cutoff line is formed in the outer cylinder, and the outer cylinder is partially or completely cut along the cutoff line to partially form the outer cylinder and the curl portion. A sealing piece is provided so as to extend between the peeled lid material and the upper surface of the lid material, and a heat-sensitive adhesive is applied to one surface of the sealing piece.

The upper end of the body is open, and after the contents are stored in the body, the lid material is adhered to the curl formed on the upper edge of the body to form the upper end of the inner container (body). The opening is closed. The body portion is generally cylindrical with the diameter of the upper portion slightly larger than that of the lower portion, but may have a constant diameter in the vertical direction, or may be a polygonal prismatic cross-section. A resin film or the like is provided on the inner surfaces of the body and the bottom as necessary.

The cut line formed on the outer cylinder is realized by, for example, a plurality of cut lines connected by a short connecting portion, a perforation that connects the cut lines intermittently, and the like.

The sealing piece is cut from the outer cylinder along the cutting line formed on the outer cylinder. The outer cylinder does not directly store the contents, but covers the outside of the body of the inner container. Therefore, even if the sealing piece is cut off from the outer cylinder, the contents will go out from there. There is no.

The sealing piece may be one that is completely cut off from the outer cylinder, or may not be completely cut off from the outer cylinder, but a part of it may be connected to the outer cylinder (continuous) and It may be partially cut from the tube.

The heat-sensitive adhesive is applied to one side of the sealing material that is partially or completely cut off from the outer cylinder. The heat-sensitive adhesive is an adhesive having the property of developing tackiness in response to heat. When the lid material adhered to the curl portion of the inner container is partially peeled off halfway and hot water is poured into the inner container, the heat from the hot water is transferred to the lid material, the inner container and the outer cylinder. The heat from the hot water poured into the inner container causes the heat-sensitive adhesive applied to one surface of the sealing piece to exhibit adhesiveness.

According to the first aspect of the present invention, the sealing piece is partially or completely cut from the outer cylinder along a cutting line to form the outer cylinder and the upper surface of the lid member partially peeled from the curl portion. Are hung over between. The heat-sensitive adhesive applied to one surface of the sealing piece adheres the sealing piece to the lid material (when the sealing piece is partially cut off), or to both the lid material and the outer cylinder. (When the encapsulant is completely cut off). The lid material once peeled off halfway is simply fastened again to the curl portion by the sealing piece, whereby the opening at the upper end of the body is resealed by the lid material.

According to the first aspect of the invention, the sealing piece cut from the outer tube along the cut line formed on the outer tube reattaches the edge of the lid member partially peeled from the curl to the curl. Therefore, it is not necessary to use another member such as a separate adhesive tape. Further, since a cutoff line is formed on the outer cylinder and the heat-sensitive adhesive is applied only to the area defined by the cutoff line (that is, the sealing piece), no special processing is required. The double container (double container) can be resealed at low cost.

This invention also provides a container without an outer cylinder (single container). The container according to the second aspect of the present invention comprises a tubular body portion having a curl portion formed at an upper edge peripheral edge thereof, a bottom portion provided at a lower end of the body portion so as to close a lower surface thereof, and being adhered to the curl portion. And a lid member for closing the upper surface of the body portion, wherein the body portion is formed into a tubular shape by bonding both side portions of the blank material, and the blank material forming the body portion is formed. Of the lid member that is partially or completely cut off from the edge portion at the edge portion on the outer side of the bonding of the both sides of the body portion and the curl portion. A sealing piece is provided continuously between the upper surface and the upper surface, and a heat-sensitive adhesive is applied to one surface of the sealing piece.

Also in the container (single container) according to the second aspect of the present invention, the sealing piece coated with the heat-sensitive adhesive on one surface is between the body portion and the upper surface of the lid member partially peeled from the curl portion. Be passed over to. The adhesiveness developed in the heat-sensitive adhesive is used by the heat transmitted from the hot water poured into the container, and the sealing piece is used as the lid material (when the sealing piece is partially cut off), or the lid material and the body. To both of them (when the sealing material is completely cut off). It is possible to easily keep the lid member, which has been peeled off halfway, in the closed state.

If the cutoff line (sealing piece) is formed on the body in the same manner as in the first aspect, the sealing piece is cut off from the body to make a hole in the body, and the contents will come out from there. In view of this, in the second aspect of the invention, the sealing piece is continuously provided at the edge of the side of the blank material forming the body that is outside the bonding. Even if the sealing piece is cut off partially or completely, there is no hole in the body.

The sealing piece provided in the container of the second invention (those continuously provided at the side edge of the body) can be used in a double container (double container). In this case, the sealing piece is connected to the edge portion of the side portion of the outer cylinder forming the double container.

In one embodiment, a crease line is formed at a position of the sealing piece that comes into contact with the curl portion when it is bridged between the outer cylinder or the body portion and the upper surface of the lid member. Since the sealing piece can be easily bent along the crease line, the sealing piece can be easily adhered to the upper surface of the lid member.

Preferably, a knob is formed at a corner of the sealing piece. When the sealing piece is cut off from the outer cylinder or the body, the knob can be pinched, and the sealing piece can be easily cut off from the outer cylinder or the body.

In one embodiment, the sealing piece is partially cut off, and the heat-sensitive adhesive is applied to at least a part of a range of the sealing piece to be overlapped with the upper surface of the lid member. There is. Since the heat-sensitive adhesive is applied in a narrow range, the amount of heat-sensitive adhesive used can be reduced.

In another embodiment, the area coated with the heat-sensitive adhesive is embossed. The sealing piece can be pressed firmly against the upper surface of the lid material, and the sealing piece can be firmly adhered to the upper surface of the lid material.

The present invention also provides an outer cylinder that constitutes the above-mentioned double container (double container).

The embodiments of the present invention will be described in detail below.

1 to 5 show the container of the first embodiment. 1 is a perspective view of the container, FIG. 2 is a partial vertical cross-sectional view of the container taken along the line II-II of FIG. 1, and FIG. 3 is a development view (blank diagram) of the outer cylinder forming the container of FIG. ), FIG. 4 is an enlarged sectional view of the outer cylinder along the line IV-IV in FIG. 3, and FIG. 5 is a perspective view of the container in the resealed state.

The container 1 of the first embodiment is a container in which the body of the container is doubled. That is, the container 1 is composed of an inner container composed of a lid member 10, a body portion 12 and a bottom portion 13, and an outer cylinder 14 provided outside the body portion 12 of the inner container. In order to make it easier to distinguish from a container (single container) which does not have an outer cylinder described in a second embodiment to be described later, the container of the first embodiment will be referred to as a “double container 1” (or “double container 1”) Call.

The body part 12 of the double container 1 is formed by bonding the side parts of the arc-shaped blank material to each other to form a cylindrical shape, then curling the upper end part to the outside and bending the lower end part to the inside. To be done. The body 12 has a cylindrical shape with a large diameter at the upper part and a smaller diameter toward the lower side, and the open upper surface is closed by the lid member 10. The upper edge peripheral end of the body 12 is wound outward, forming a so-called curl portion 11. The bottom portion 13 has a circular shape, and its peripheral end portion is bent downward (bent portion 13A). The bottom portion 13 fits snugly into the lower surface opening of the body portion 12, the lower end portion of the body portion 12 is folded inward (folded portion 12A), and the folded portion 12A sandwiches the bent portion 13A of the bottom portion 13. The inner and outer surfaces of the bent portion 13A of the bottom portion 13 and the inner surface of the folded portion 12A at the lower end portion of the body portion 12 that sandwiches the bent portion 13A are adhered or welded by a thermoplastic resin.

In the lid member 10, a sealant layer for adhering the lid member 10 to the upper surface of the curl portion 11, a paper layer for printing characters, figures, etc., a protective layer for protecting the paper layer, etc. are laminated in multiple layers. Is used. An aluminum layer for shape retention may be laminated between the sealant layer and the paper layer. For the body 12 and the bottom 13, for example, a paper base material and a laminated structure such as a polyethylene film laminated on the inner surface thereof are used.

The outer cylinder 14 is formed by adhering side portions of an arc-shaped blank material (FIG. 3) to each other and adhering them together to form a cylindrical shape, and then bending the lower end portion inward (bending portion 14A). . An adhesive portion used for adhering the side portions is indicated by reference numeral 14B in FIG. The bent portion 14A at the lower end may be folded as shown in FIG. 2 or may be a curl portion wound inside. The doubled part when folded may be adhered by an adhesive.

Like the body 12, the outer cylinder 14 also has a cylindrical shape with a large upper diameter and a smaller diameter toward the bottom. The inner container is inserted (fitted) into the outer cylinder 14 from the bottom thereof. The upper end portion of the outer cylinder 14 enters a gap inside the curl portion 11 at the upper end edge of the body portion 12, and the lower end portion extends along (contacts) the lower end portion of the body portion 12. The outer cylinder 14 is fixed to the inner container with an adhesive. For example, the bent portion 14A at the lower end portion of the outer cylinder 14 and the body portion 12, or the upper end portion of the outer cylinder 14 and the curl portion 11 or both of them can be bonded. It is preferable that the lower end of the outer cylinder 14 does not protrude below the lower end (thread twist) of the body portion 12. However, the lower end of the outer cylinder 14 may be made to project below the lower end of the body 12 so that the entire double container 1 is supported by the outer cylinder 14. Further, the lower end of the outer cylinder 14 may be extended straight without folding. In any case, a gap (heat insulating space) 18 is formed between the outer surface of the body 12 and the inner surface of the outer cylinder 14.

Referring to FIGS. 1 and 3, a substantially rectangular sealing piece 21 is partitioned on the outer cylinder 14 by a cut line 21A and a crease line 21C formed on the outer cylinder 14. The crease line 21C defines the upper edge of the substantially rectangular sealing piece 21, and the rest is defined by the cut line 21A. The cutoff line 21A is realized by, for example, a plurality of short cut lines connected by short connecting portions, a perforation that connects the cut lines intermittently, or the like. The shape of the sealing piece 21 is not limited to a square shape, and may be a circle, an ellipse, a triangle, or any other shape.

A cutoff line 21A is formed so as to bulge outward in an arc shape only in the lower left corner of the sealing piece 21, and the outwardly bulging portion serves as a grip portion 21B when the sealing piece 21 is separated from the outer cylinder 14, as described later. Used.

Approximately the center of the sealing piece 21 has a fold line 21D formed horizontally. The fold line 21D is formed to facilitate bending of the sealing piece 21 at that position, and will be described in detail later.

Referring to FIG. 4, a heat-sensitive adhesive 31 is thinly applied, for example, in a thickness of 1 to 30 μm, on the surface of the outer cylinder 14 in the area where the sealing piece 21 is partitioned. The heat-sensitive adhesive 31 is of a type that does not have tackiness at room temperature and develops tackiness when heat of 40 ° C to 90 ° C is applied. For example, water, dicyclohexyl phthalate, synthetic resin (for example, vinyl chloride). (Vinyl chloride / vinyl acetate copolymer), acrylic, polyurethane, polystyrene, polyester, epoxy, nitrocellulose (nitrified cotton), ethyl cellulose, polyamide, cyclized rubber, chlorinated polyolefin, photocurable resin, etc. It is possible to use a sticky-sustaining type in which an auxiliary agent (for example, an antioxidant, a lubricant, a defoaming agent, etc.), aqueous ammonia, or mineral oil is added thereto. In FIGS. 1 and 3, the area where the heat-sensitive adhesive 31 is applied is shown by a dot pattern. This also applies to the modified examples and other embodiments described below.

The part where the cutoff line 21A is formed, that is, both side edges and the lower edge of the sealing piece 21 are cut out from the outer cylinder 14. When the both side edges and the lower edge of the sealing piece 21 are cut out from the outer cylinder 14, the grip portion 21B is used. For example, by putting a nail on the cutoff line 21A at the position of the picked portion 21B, the picked portion 21B is floated, and the lifted picked portion 21B is picked with a finger and pulled outward, so that the two edges of the sealing piece 21 are cut along the cutoff line 21A. The lower edge and the outer cylinder 14 can be easily separated.

The cut line 21A is not formed on the upper edge of the sealing piece 21, and is still connected to the outer cylinder 14 at the crease line 21C. Referring to FIG. 5, the sealing piece 21 is not completely cut (not separated) from the outer cylinder 14 and can be folded back upward at the position of the crease line 21C (half-rotation around the crease line 21C). . Further, the sealing piece 21 is bent inward along the folding ruled line 21D formed substantially in the center of the sealing piece 21. A fold line 21D is formed at a position that comes in contact with the curl portion 11 when folded back upward at the position of the fold line 21C. When the sealing piece 21 is folded inward along the fold line 21D, the fold line 21D is folded. A range closer to the tip than the ruled line 21D is overlaid on the lid material 10. In this way, the sealing piece 21 is hung from the outer cylinder 14 to the upper surface of the lid member 10.

For the sealing piece 21, the lid material 10 is peeled halfway to open the upper end of the inner container, hot water is poured into the inner container from the opening, and the lid material 10 peeled halfway is returned to its original position and the opening is opened again. It is used for easily fixing (holding) the lid member 10 to the container 1 when closing (resealing). Since the lid 10 is warmed to 40 ° C. or higher by the hot water poured into the inner container, the adhesiveness of the heat-sensitive adhesive 31 applied to the surface of the sealing piece 21 which is superposed on the lid 10 is developed. Since the sealing piece 21 suppresses the force of the lid material 10 opening upward, the opening of the inner container is easily resealed by the lid material 10.

Since a part of the outer cylinder 14 constituting the container 1 is used as the sealing piece 21, a separate member (for resealing the opening of the container 1 by returning the lid member 10 that has been partially removed to the original position) ( It is not necessary to prepare adhesive film, tape, etc.). Since the cut line 21A and the

crease lines

21C and 21D are formed on the outer cylinder 14 (the sealing piece 21 is defined on the outer cylinder 14), and the heat-sensitive adhesive 31 may be applied to the surface of the sealing piece 21, The resealing function of the container 1 is realized at low cost.

When the lid material 10 is completely peeled off, the sealing piece 21 may be peeled off from the lid material 10, and then the lid material 10 may be peeled off. Alternatively, without peeling the sealing piece 21 from the lid material 10, the sealing piece 21 may be peeled off. 21 may be completely separated from the outer cylinder 14 along the crease line 21C, and the lid member 10 to which the sealing piece 21 is adhered may be peeled off. When the sealing piece 21 is to be completely separated from the outer cylinder 14 along the crease line 21C when the lid material 10 is peeled off, the crease line 21C is provided with, for example, a half-cut line to facilitate the separation. It is better to form it.

As shown in FIGS. 6 and 7, instead of applying the heat-sensitive adhesive 31 to the entire surface of the sealing piece 21, the heat-sensitive adhesive is applied to a narrow area of the sealing piece 21 that is overlaid on the lid member 10. 31 may be provided. In addition, the embossed portion 21E (outwardly convex area) may be formed in a narrow area on the sealing piece 21 on which the heat-sensitive adhesive 31 is provided. The amount of the heat-sensitive adhesive 31 used can be reduced, and the sealing piece 21 can be easily pressed onto the lid member 10, so that a firm sealing can be realized.

There are various possible shapes and structures of the sealing pieces.

FIG. 8 is a development view (blank diagram) of the outer cylinder 14 including the sealing piece 22 of the modified example. A point where the heat-sensitive adhesive 31 is applied to a range closer to the tip side than the crease line 21D to be overlapped on the lid material 10, and a range where the heat-sensitive adhesive 31 is applied to the tip side than the crease line 21D. Has a trapezoidal shape, which is different from the sealing piece 21 (see FIGS. 1 and 3) described above. The sealing piece 22 can be adhered to the lid material 10 over a wide area.

FIG. 9 is a development view (blank diagram) of an outer cylinder 14 including a sealing piece 23 of still another modification. The sealing piece 23 has a substantially concave shape, and while keeping the sealing piece 23 connected to the outer cylinder 14, the fold line 21C where the sealing piece 23 is folded back is The left and right sides are short and spaced from each other. Since the length of the crease line 21C is short, it is easy to tear off the sealing piece 23 from the outer cylinder 14 at the crease line 21C, and when the lid material 10 is completely peeled off, the sealing piece 23 is also separated from the outer cylinder 14 together. It will be easy.

FIG. 10 is a development view (blank diagram) of the outer cylinder 14 including a sealing piece 24 of still another modification. FIG. 11 shows how the lid member 10 is simply resealed using the sealing piece 24 shown in FIG. The shape of the sealing piece 24 is the same as that of the sealing piece 21 shown in FIGS. 1 and 3, but the point formed on the slightly lower side of the outer cylinder 14, the folding line 21C is not formed, and the cut line 21A is formed. This is different from the sealing piece 21 described above in that the entire circumference is surrounded by.

The sealing piece 24 is completely separated from the outer cylinder 14 along the cutoff line 21A. With reference to FIG. 11, the sealing piece 24 completely separated from the outer cylinder 14 is partially superposed on the lid member 10 and the other part is superposed on the outer cylinder 14, respectively. To the upper surface of the lid member 10 and are bonded to both the lid member 10 and the outer cylinder 14. Referring to FIG. 2, in the double container 1, the gap 18 between the inner container (body 12) and the outer cylinder 14 is relatively narrow in the upper part of the container 1, and the heat of the hot water poured into the inner container is In the upper part of the container 1, it is relatively easy to be transmitted to the outer cylinder 14. In both the range overlaid on the lid member 10 and the range overlaid on the outer cylinder 14, the heat-sensitive adhesive 31 of the sealing piece 24 exhibits tackiness, and the lid member 10 can be easily resealed. .

In the sealing piece 24 of the type that is completely separated from the outer cylinder 14, the heat-sensitive adhesive 31 may be applied to the front side of the outer cylinder 14 (the surface facing the outside in the container 1) or the back side (the inside of the container 1). May be applied to the surface facing toward.

The container 2 of the second embodiment is a single container that does not have the outer cylinder 14 of the double container 1 of the first embodiment.

Referring to FIG. 14, a sealing piece 25 is continuously provided at an edge of one side of the body 12 that constitutes the single container 2. A cutoff line 25B is formed on the boundary of the body portion 12 with the sealing piece 25 except for the connecting portion 25A at the upper end portion. At the boundary position between the connecting portion 25A and the cutoff line 25B, a fold line 25C is formed on the sealing piece 25 in a lateral direction.

Referring to FIG. 12, when the side portions of the blank material of the body portion 12 are adhered and bonded to each other to form the cylindrical body portion 12, the end portion where the sealing piece 25 is connected to the outside, The opposite side is placed inside and the sides are attached together. As a result, the sealing piece 25 is located outside the body 12.

The sealing piece 25 on the lower side of the crease line 25C is separated from the body 12 along the cut line 25B. The portion above the crease line 25C is still connected to the body portion 12 at the connecting portion 25A. Referring to FIG. 15, the sealing piece 25 is folded back upward at the position of the crease line 25C (half-rotation around the crease line 25C), and the tip portion of the sealing piece 25 is superposed on the lid member 10. The tip portion of the sealing piece 25 is adhered to the lid member 10 by the heat-sensitive adhesive 31 applied to the surface of the sealing piece 25.
