DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to detergents (for clothing, kitchens, houses, vehicles, etc.), beverages (soft drinks, milk, water, etc.) and foods (soy sauce, sauces, sauces, etc.). The present invention relates to a blow bottle with a sleeve, which is suitably used for a main body or for refilling.

[0002]

2. Description of the Related Art Conventionally, when a hollow plastic container such as a blow bottle has no stability, a combination of a paperboard sleeve with open ends on the outside of the bottle is used to reinforce this. Among these types of blow bottles with sleeves, the one described in Japanese Patent Publication No. 4-506330 is known as one having a handle for gripping. This is shown in FIGS.
One of the two corners is provided with a recess 5, whereas the sleeve 6 has two handle openings 7 in this area,
At the corner indicated by reference numeral 8, the punched flap portion indicated by reference numeral 9 is folded inward and adhered or fixed to the projection 10 so that the handle portion is constituted only by the sleeve 6.

[0003]

In the blow bottle with a sleeve described in the prior art, the handle is formed only on the sleeve without being formed on the bottle itself. Is preferable in the case of the bottle, but the handle portion is formed only by bending the paperboard, so the strength is weak, and the handle portion is deformed when a heavy object such as liquid is put. There is a point.

[0004] The present invention has been made in view of the above problems, and an object of the present invention is to provide a blow bottle with a sleeve in which the handle formed on the sleeve has an increased strength.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention comprises a spout at the tip of a shoulder connected to the upper side of a rectangular tubular body, and a spout at the shoulder. And a four-side panel inserted so as to cover the body of the blow bottle from the support edge to the bottom of the blow bottle. A blow-bottle with a sleeve, comprising a sleeve made of paperboard in the shape of a rectangular tube, wherein a recess is provided in a part of one corner of a body of the blow-bottle, and an adjacent side panel is provided inside the sleeve. And a handle portion having a triangular horizontal cross section that enters the recess so as to be located between the openings provided in the blow bottle. The handle portion extends from the recess to the bottom at the corner of the blow bottle. A small cutout portion is provided, and the handle portion of the sleeve is formed into a rectangular tube shape composed of four side panels by gluing a piece of paperboard with a glue margin piece, and is connected to the glue margin piece. The flap piece is formed by bending the flap piece through the opening of the side panel adjacent to the margin piece and extruding the tip portion outward, and bending the tip portion of the flap piece protruding outside and bonding it to the outer surface of the side panel. It is characterized by having. And
As the blow bottle, a blow bottle provided with a plurality of slits for crushing from the bottom to the lower half of both sides facing each other may be used.

[0006]

In the blow bottle with a sleeve according to the present invention having the above-mentioned structure, a handle portion is formed by using a margin piece of the sleeve, and the handle portion has a double triangular outer side. Demonstrate high strength because it is.
In addition, the cut portion provided below the hollow of the blow bottle causes the handle portion to be introduced in a compressed state when inserting the blow bottle into the sleeve, and at the same time as the insertion is completed, the handle portion is released from the compressed state and in the hollow. It will be in a spread-fit state.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a blow bottle with a sleeve according to the present invention. The blow bottle with a sleeve 1 shown in FIG. 1 comprises a blow bottle 2 shown in FIG. 2 and a sleeve 3 shown in FIG. Become.

The blow bottle 2 is a thin-walled blow-molded high-density polyethylene (HDPE) resin having a minimum amount of resin necessary for forming the bottle. A shoulder 22 having a spout is provided. Around the shoulder 22, a supporting edge 22 a is projected from a boundary with the body 21. A recess 23 is provided in a part of one corner of the body 21, and a cut portion 25 is provided in this corner from the recess 23 to the bottom 24. Furthermore, two slits 26 for crushing are provided from the bottom 24 having a tapered periphery to the lower half of the opposite side surfaces of the body 21. A cap 27 is screwed into the spout. In addition, as the resin forming the blow bottle 2, in addition to the above HDPE, polypropylene (PP), polyethylene terephthalate (P)
ET) may be used. Further, a multilayer may be used to impart gas barrier properties. For example, PP / ethylene-vinyl alcohol copolymer (EVOH) / PP, low density polyethylene (LDPE) / EVOH / PP, etc. may be used. .

The sleeve 3 is formed by assembling a paperboard whose development is shown in FIG. In this paperboard, side panels 32 to 35 are sequentially connected to a glue margin piece 31 via folding rules a to d.
Further, a flap piece 36 is continuously provided on the edge side of the margin piece 31 via a crease e. The glue piece 31 is adhered to the inner surface of the end of the side panel 35 on the opposite side, and sack-pasted. After being raised and formed into a rectangular tube shape, as shown in FIG. 3, the flap piece 36 is bent by a crease e so as to pass through the opening 32a of the side panel 32, and its tip portion 36a is exposed to the outside, and the tip portion exposed to the outside is obtained. The handle portion 37 is formed by bending the side 36a with the folding rule f and bonding it to the outer surface of the side panel 32. As described above, the handle portion 37 has a triangular horizontal cross-sectional shape, and although one inner side (the inner wall 36b) is a single sheet, the outer two sides are doubled to increase the strength. The margin piece 31 may be adhered to the end surface of the side panel 35 and stuck. In this case, the flap piece 36 passes through the opening 35 a of the side panel 35 and then exits through the opening 32 a of the side panel 32. Here, the size of the flap piece 36 and the openings 32a and 35a are determined so that the vertical length of the handle portion 37 is substantially the same as that of the depression 23 of the blow bottle 2, and the blow bottle 2 is inserted into the sleeve 3. At this time, the handle portion 37 fits into the depression 23 of the blow bottle 2.

To attach the sleeve 3 to the blow bottle 2, the handle portion 37 of the sleeve 3 and the recess 23 of the blow bottle 2 are oriented in the same direction, and the blow bottle 2 is inserted from above the sleeve 3. In this case, since the bottom portion 24 of the blow bottle 2 is tapered, and the cut-out portion 25 is provided at the lower corner of the recess 23, the handle portion 37 is pressed after the blow bottle 2 easily enters the sleeve 3. Inserted in the inserted state. At the same time, the handle portion 37 is released from the pressed state and is spread and fitted in the recess 23 of the blow bottle 2 while the support portion 22a of the blow bottle 2 is inserted until the support edge 22a contacts the upper end of the sleeve 3. Then, the inner wall 36b of the handle portion 37
Are fixed in the recess 23 by being stretched up and down.

The above-mentioned blow bottle 1 with a sleeve has a strong handle portion 37, so that the entire body can be lifted firmly and used safely even in a heavy state containing liquid. Further, at the time of disposal after use, the blow bottle 2 and the sleeve 3 can be easily separated. The volume of the separated blow bottle 2 can be reduced by the slit 26, and the sleeve 3 can also be folded to reduce the volume. The blow bottle with a sleeve of the present invention may of course use a normal blow bottle without a slit for crushing.

[0013]

As described above, in the blow bottle with a sleeve of the present invention, a handle portion having a triangular horizontal cross section is formed by using a margin piece of the sleeve, and two outer sides of the triangle are doubled. With such a configuration, it is possible to use a handle having high strength while using as little molding material as possible.
