Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention includes detergents (for clothes, kitchen, housing, vehicles, etc.), beverages (soft drinks, milk, water, etc.), foods (soy sauce, sauces, sauces, etc.). The present invention relates to a blow bottle with a sleeve, which is a container for storing various liquids and is preferably used for a main body or for refilling.

[0002]

2. Description of the Related Art In recent years, plastic blow bottles have been widely used in place of conventional glass bottles because they are lightweight and easy to carry as a main body container for storing the above liquids. In addition, as a refill container, a standing pouch that is easy to dispose is now mainly used.

[0003]

The blow bottle described in the prior art has the advantage that it is lighter and easier to handle than a glass bottle, but since it is a thick blow bottle, it is strong and therefore bulky without being crushed at the time of disposal. There is a problem that it will stretch. On the other hand, a standing pouch for refilling is good in terms of volume reduction because it is a soft packaging material, but there is a problem that it is difficult to transfer the contents.

The present invention has been made in view of the above problems, and an object of the present invention is to satisfy the conditions required for containers such as filling suitability, transport suitability, store effect, and strength. It is an object of the present invention to provide a blow bottle with a sleeve that can be easily separated by material at the time of disposal and can be individually reduced in volume.

[0005]

In order to achieve the above object, a blow bottle with a sleeve of the present invention has a substantially rectangular horizontal cross section and is crushed from the bottom to the lower halves of opposite sides of the body. A thin blow bottle having a plurality of slits, and a rectangular tube shape inserted so as to cover the body of the blow bottle between the support edge portion provided around the shoulder portion of the blow bottle and the bottom portion. A board-made sleeve of the blow bottle, each of which has an inwardly concave portion on each side of the blow bottle where the slit is provided and which contacts the supporting edge portion, and the sleeve has a flap piece corresponding to the concave portion. It is characterized by.

A ridge may be provided so as to vertically cut the middle of both sides of the blow bottle where the slit is not provided. In this case, the ridge is provided on both sides on the long side of the blow bottle. It is preferable.

[0007]

In the blow bottle with sleeve of the present invention having the above-mentioned structure, the flap piece of the sleeve inserted into the blow bottle is fitted into the recess of the blow bottle and locked, whereby the sleeve is fixed to the blow bottle, and the sleeve is In this mounted state, it serves to reinforce the blow bottle. The sleeve and the blow bottle can be easily separated at the time of disposal, and the separated blow bottle can be reduced in volume by crushing at the slit portion, and the sleeve can also be folded to reduce the volume.

Further, the ridges provided on the blow bottle serve to increase the strength of the blow bottle and also fill the gap between the inserted sleeve and the blow bottle. (Tensioned), which results in reliable locking of the flap piece of the sleeve and the recess of the blow bottle.

[0009]

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. A blow bottle with a sleeve 1 in the figure comprises a blow bottle 2 shown in FIG. 2 and a sleeve 3 shown in FIG. Become.

The blow bottle 2 is a thin one made by blow molding high density polyethylene (HDPE) having a minimum amount of resin required to form the bottle, and as shown in detail in FIGS. The horizontal cross-section has a substantially rectangular shape, and a shoulder portion 23 having a spout 22 is provided above the body portion 21, and a supporting edge portion 23a is provided around the shoulder portion 23 at the boundary with the body portion 21. Three slits 25 for crushing are provided from the bottom portion 24 to the lower halves of the opposite side surfaces of the body portion 21 on the opposite short side. Furthermore, the slit 25
On both sides of the short side provided with the recessed portions 26, which are inwardly inclined downward, are provided at the portions in contact with the support edges 23a on both sides of the short side, and the middle of the side surfaces on the long side where the slit 25 is not provided is cut longitudinally. Thus, the ridge 27 is provided. A cap 28 is screwed onto the spout 22. In addition, as the resin forming the blow bottle 2,
In addition to DPE, polypropylene (PP), polyethylene terephthalate (PET) or the like may be used. Further, it may have a multi-layer structure for imparting a gas barrier property, for example, a PP / ethylene-vinyl alcohol copolymer (EV).
OH) / PP, low density polyethylene (LDPE) / EV
OH / PP or the like may be used.

The sleeve 3 is formed by assembling a paperboard whose development view is shown in FIG. This paperboard has a series of adhesive pieces 31, a narrow panel 32, a wide panel 33, a narrow panel 34, and a wide panel 35, which are arranged in order through creases a to d, and is further folded at the upper ends of the narrow panels 32, 34. Flap pieces 36 and 37 are connected in series via e and f, respectively, and an adhesive piece 31 is adhered to the inner surface of the end of the wide panel 35 on the opposite side and sack-attached to raise it into a rectangular tube shape. As a result, the sleeve 3 shown in FIG. 3 is formed. Here, narrow panel 3
The widths of the blown bottles 2 and 34 are substantially equal to the short sides of the blow bottle 2, the widths of the wide panels 33 and 35 are substantially equal to the long side of the blow bottle 2, and the heights of the panels 32 to 35 are the same as those of the blow bottle 2. The length is from the supporting edge portion 23a to the bottom portion 2. Further, the flap pieces 36 and 37 are sized to fit in the recesses 26 of the blow bottle 2.

To attach the sleeve 3 to the blow bottle 2, the flap pieces 36 and 37 of the sleeve 3 are folded back inward along the folding lines e and f, and the blow bottle 2 is inserted from above the sleeve 3. Then, when the supporting edge portion 23a of the blow bottle 2 is inserted until it abuts on the upper end of the sleeve 3, the flap pieces 36 and 37 of the sleeve 3 are fitted into the concave portion 26 of the blow bottle 2 by the repulsive force of the paperboard, and the sleeve 3
Is fixed along the body portion 21 of the blow bottle 2. As a result, the sleeve 3 becomes the shoulder portion 2 of the blow bottle 2.
3 It is set in a state where the cylinder is erected from the lower edge to the bottom 24. In this case, since the ridges 27 are provided in the middle of both side surfaces of the long bottle side of the blow bottle 2, the sleeve 3 is spread by the ridges 27 and becomes a hexagonal shape, and is firmly attached in a tensioned state. , The flap pieces 36 and 37 are surely locked.

[0014]

Since the present invention is constructed as described above, it has the following effects.

By attaching a paperboard sleeve to the body of a blow bottle that is thin and crushable, it is possible to reinforce a blow bottle having a weak strength and bring it into a usable state having a required strength. . Also, since the blow bottle and sleeve are configured to lock due to the relationship between the bending of the paperboard and the shape of the blow bottle without using an adhesive,
Both can be easily separated at the time of disposal, and the volume of both the blow bottle and the sleeve that have been separated can be reduced.

Further, by providing a ridge so as to vertically cut the middle of both sides of the blow bottle which are not provided with slits, the strength of the blow bottle is increased and the inserted sleeve has a tension state. It can be mounted without rattling, and the sleeve can be reliably locked with respect to the blow bottle.
