Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a jug bottle in which a pressure-resistant bottle for containing draft beer or the like is formed into a jug shape so that it can be used as a jug immediately after opening. It is related.

"Problems to be solved by conventional techniques and ideas" Bottles made of pressure-resistant synthetic resin for containing draft beer and the like are already well known. In general, this pressure-resistant synthetic resin bottle is made by injection-molding a saturated polyester resin preform and further biaxially stretch-molding it to form a narrow-necked thin-walled bottle whose bottom and shoulder bulge spherically. And the injection-molded hakama and the cover are fitted on the shoulder.

It would be convenient if such a bottle could be used as a mug immediately after opening, but it is impossible to make a mug as it is because of its narrow mouth, and it is the current situation that it is not commercially available.

By the way, in a conventional chemical container in which a cap is attached to the narrow mouth portion of the container body, a breaking line and a pull ring are provided on the top wall of the cap, and the pull ring is pulled strongly to open the top wall. There is one in which a breaking opening is formed at a breaking line (Japanese Patent Laid-Open No. 58-171356).
In addition, there is a container body in which a liquid is contained, in which a narrow mouth portion is equipped with a stopper with a handle (Japanese Utility Model Publication No. 54-30126). It should be noted that these containers do not take pressure resistance into consideration, and as they are, they are not suitable for storing draft beer and the like, and of course, they cannot be made into mugs.

The present invention has been obtained by improving and developing the conventional pressure resistant synthetic resin bottle containing draft beer and the like by adding the above-mentioned opening means for breaking the cap top wall and attaching the handle to the cap as described above. It is intended to be a mug that could not be used and to be used as a mug immediately after opening, and it is intended to be convenient to use, easy to drink and good looking. .

[Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention mounts a large pressure resistant cap 2 on the mouth 11 of a pressure resistant wide-mouthed bottle 1 and uses a large top wall 21 of the cap. The handle 3 is constructed so that it can be opened in a rupturable manner, and a handle 3 that hangs downward from the peripheral wall 22 of the cap 2 is provided in a projecting manner, and an engaging piece 35 for connection is provided at the lower end of the handle, and the wide mouth bottle 1 It is characterized in that the hakama 4 is fitted on the bottom portion 14, and a locking piece 43 which engages with the engaging piece 35 is projectingly provided on the peripheral wall 41 of the hakama so as to be engaged and connected with each other.

[Operation] As described above, the cap 2 is initially removed, the contents such as draft beer are stored in the wide-mouthed bottle 1, and then the cap 2 is attached to the mouth portion 11 to seal the contents. , The engaging piece 35 at the lower end of the handle 3 is engaged and connected to the engaging piece 43 of the hakama 4.

When it is used for drinking, the top wall 21 of the cap 2 is broken and opened in a large opening. As a result, the entire container becomes a mug, so that after that, the handle 3 can be grasped and the contents can be immediately drunk.

"Embodiment" Figs. 1 and 2 show an embodiment relating to a synthetic resin jug bottle of the present invention.

In the illustrated example, a large pressure resistant cap 2 is screwed onto the mouth portion 11 of the pressure resistant wide-mouthed bottle 1 so that the top wall 21 of the cap can be opened by large opening and the peripheral wall of the cap 2 can be opened.
A handle 3 that hangs downward from 22 is integrally projected, and a hakama 4 is fitted to the bottom of the wide-bottle 1 to connect a peripheral wall 41 of the hakama and a lower end of the handle 3.

The wide-mouthed bottle 1 is formed by biaxially stretching and molding with a saturated polyester resin. First, a thick preform with only the mouth portion 11 having a thread 12 on the outer periphery in a completed shape is injected with a saturated polyester resin. Then, the preform is biaxially stretch-molded in the lower portion of the mouth portion 11, and the body portion 13 to the bottom portion 14 are thin-walled, and the bottom portion bulges downward, and the periphery of the bottom portion is formed. It is formed as a thin-walled pressure resistant bottle having a fitting groove 15 at the bottom.

The cap 2 has a circular top wall 21 formed by pressing an aluminum plate, and a large circular endless break line 23 is formed on the top surface of the top wall.
Along with engraving, the pull ring 24 is continuously provided inside the surrounding of the endless fracture line, the peripheral wall 22 injection-molded with a synthetic resin is continuously provided in a watertight manner to the peripheral edge of the top wall 21, and the inner wall of the peripheral wall is continuously provided. Thread
25 is provided so as to be screwed to the mouth portion 11 of the wide-mouthed bottle 1 with the peripheral wall, and a ring-shaped packing 26 is provided between the top surface of the mouth portion 11 and the inner surface of the top wall 21. Intervenes.
The top wall 21 and the peripheral wall 22 may be joined together by molding when the peripheral wall is molded, or may be integrated by joining with ultrasonic waves or an adhesive.

The handle 3 has an arm piece 31 integrally projecting from the rear surface of the peripheral wall 22 of the cap 2, and extends from the tip of the arm piece to the lower part of the hakama 4 through the first thin hinge 32 in a strip shape. Gripping piece
33 is vertically suspended, and the second thin hinge is attached to the lower end of the gripping piece.
A hook-shaped engagement piece 35 is provided via 43, and the above is integrally formed by injection molding with the peripheral wall 22 of the cap 2.

As shown in FIG. 3, the handle 3 is provided separately from the cap 2, and the base 31'a of the arm piece 31 'is formed into a hook shape to engage with the peripheral wall 22 of the cap 2. You may allow it.

The hakama 4 is formed by injection-molding a synthetic resin as appropriate, is formed in an appropriate shape corresponding to the bottom portion 14 of the wide-mouth bottle 1, and a ridge 42 is provided around the inner edge of the upper end of the peripheral wall 41 to form the wide-mouth. It is fitted into the fitting recess 15 of the bottle 1 and fits into the bottom 14 thereof, and a planar U-shaped locking piece 43 is integrally projectingly provided on the upper rear surface of the peripheral wall 41 to lock the same. The engaging piece 35 of the handle 3 is inserted into and engaged with the piece. Note that this engagement is performed after filling the contents in the wide-mouthed bottle 1 and screwing the cap 2 on.

With the above configuration, the wide-mouthed bottle 1 stores draft beer or the like in a sealed manner, but when used for drinking, the cap 2 is used.
In, when the pull ring 24 is hooked with a finger and pulled up strongly, and the top wall 21 is broken along the endless break line 23 to open, the bottle becomes a mug as it is. Therefore, the handle 3 may be pulled out rearward and grasped for drinking.

The wide-mouthed bottle 1 and the cap 2 have sufficient pressure resistance to accommodate draft beer and the like, and, in terms of material, do not exude a solvent that may be harmful to the human body.

[Advantage of the Invention] According to the present invention, the bottle can be opened in a large opening at the top wall 21 of the cap 2, and the handle 3 which hangs downward from the peripheral wall 22 of the cap is provided so as to project. Since the engagement piece 35 at the lower end of the bottle is engaged and connected to the locking piece 43 projecting from the peripheral wall 41 of the hakama 4, the top wall 21 of the cap 2 is ruptured and opened by a large opening, and the bottle becomes a jug as it is.
Immediately after the breaking opening, it can be served as a jug for drinking.

Furthermore, since the cap 2 is attached to the mouth portion 11 of the wide-mouthed bottle 1 and the hakama 4 is fitted to the bottom portion, the mouth portion 11 and the bottom portion 14 of the wide-mouthed bottle 1 having weak mechanical strength can be reinforced from the outside, In particular, the bottom portion 14 can be bulged into a spherical shape to increase the mechanical strength from the form, and can secure a sufficient pressure resistance for storing draft beer and the like. Moreover, the appearance can be made beautiful and the appearance can be improved, and it can also be used in vending machines, which is very convenient and convenient.
