Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to beverage containers. More particularly, the invention relates to a beverage container in which a straw is housed inside the container body. The present invention is suitable to be applied to a beverage container which is previously filled with a beverage and sold, but can also be applied to a container in which a user puts a beverage and uses it.
[0002]
[Prior art]
Drinking straws are distributed separately from the beverages sold in the form of containers, and users who want to drink the container-filled beverages must store the straws each time they drink. There is the inconvenience of having to take it out of the place and use it. Also, in a beverage container in which a user puts a beverage and uses it, it is inconvenient for the user that the container and the straw are separate.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a beverage container with a straw in which a straw is stored in a beverage container in advance and which is inexpensive and convenient to use.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the present invention, a straw component is disposed in a container body having a mouth and formed in a hollow shape with a flexible film material. The straw structure is composed of an outer straw and an inner straw. In a preferred embodiment, the outer straw is formed of a material that is relatively rigid compared to the container body, one end of which is fixed to the mouth of the container body and the other end is located near the bottom of the container body and away from the bottom. I do. The inner straw is slidably inserted in the outer straw in the length direction, and one end is located at substantially the same position as the one end of the outer straw, and the other end projects from the other end of the outer straw toward the bottom of the container body. I do.
In one embodiment of the present invention, the outer straw is fixed to the mouth of the container body via a plug member fixed near one end.
[0005]
In the container body, a cap portion for closing the mouth portion can be integrally formed. In this case, a perforation or score line for separating the cap portion between the cap portion and the mouth portion is cut off. A scheduled portion can be formed. In the case of this embodiment, the container main body is provided with a beverage filling port other than the mouth, and after filling the beverage, the beverage filling port is sealed. The beverage filling port can be formed by the bottom of the container body, and the bottom can be sealed after filling the beverage.
[0006]
The end of the inner straw can be provided with a removable cap. The inner straw may have a bellows-like bent portion at a position away from the one end. In the present invention, the container body is preferably formed of a transparent resin material, but may be formed of another material.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Referring to FIGS. 1 and 2, these figures show a beverage container main body 1 in which the present invention is implemented before a beverage is filled. Referring to FIG. 3 showing a cross section, the container main body 1 includes front and rear wall sheets 2 and 3 and a pair of side wall sheets 4 and 5. Each of the sheets 2, 3, 4, and 5 is formed of a flexible transparent material such as polyethylene or polypropylene, and the edges are overlapped and joined by heat sealing to form the hollow bag-like container body 1. In the figure, reference numeral 6 denotes a heat seal joint.
[0008]
As shown in FIG. 1, the container main body 1 includes a bottle neck-shaped mouth portion 7. The mouth 7 is heat-sealed by sandwiching the sheet 4 between the sheets 2 and 3 at one edge, and heat-sealed by sandwiching the sheet 4 between the sheets 2 and 3 at the other edge. It is formed in a shape having a passage 8 in the center. The end of the mouth 7 is sealed by a cap 9 formed by heat sealing. In order to separate the cap portion 9 from the mouth portion 7 so that the mouth portion 7 can be opened, a portion 10 to be separated such as a perforation or a score line is formed between the cap portion 9 and the mouth portion 7. FIG. 4 shows the shape around the mouth of the container body 1.
[0009]
Inside the container body 1, a straw constituting body 11 is arranged. The straw construct 11 includes an outer straw 12 and an inner straw 13 fitted in the outer straw 12 so as to be slidable in the length direction. One end of the inner straw 13 is closed by a cap 14. One end of the inner straw 13 and one end of the outer straw 12 are inserted into a central passage 8 formed in the mouth 7 of the container body 1, and the one end of the outer straw 12 is connected to the container by a suitable bonding means such as heat sealing. It is fixed to the mouth 7 of the main body 1.
[0010]
The outer straw 12 is formed to have higher rigidity than the sheets 2, 3, 4, and 5 of the container body 1. The inner straw 13 has a longer dimension than the outer straw 12. It is desirable that the length of the inner straw 13 is about 10 to 15 mm longer than that of the outer straw 12 and that the inner straw 13 protrudes from the end of the outer straw 12 by this dimension. It is desirable that the inner straw 13 has a bellows-like elastic portion 15 at a position away from one end.
[0011]
The lower part 16 of the container body 1 is open in the state shown in FIG. The beverage is filled with the container body 1 in an inverted state, and then the lower part of the container body 1 is sealed with a sheet seal 17. In this state, the beverage-filled container with a straw is distributed and sold. The container in the beverage filled state is shown in FIGS.
[0012]
The customer who purchased the beverage-filled container with a straw first cuts off the cap portion 10 along the predetermined line 10 so that the end of the straw structure 11 is exposed. In this state, when the container is placed on a flat table 18 such as a table as shown in FIG. 8, the container body 1 is bent downward by the weight of the beverage inside, and as a result, the inner straw 13 is pushed up by the table 18. Then, the upper end of the inner straw 13 projects from the upper end of the outer straw 12. Here, the cap 14 is removed, and as shown in FIG. 9, the inner straw 13 can be pulled out to drink the beverage inside the container. Even if the container is not placed on the flat base 18, the upper end of the inner straw 13 protrudes from the upper end of the outer straw 12 by simply grasping the bottom of the container main body 1 by hand, or simply pressing the lower end of the inner straw 13 from the bottom of the container main body 1. Can be done.
[0013]
This container can be manufactured at a lower cost than PET bottles and paper packs. By making the inner straw 13 of the bellows type, it becomes convenient to drink the internal beverage, and the sick person or the like can drink the beverage without spilling even while sleeping.
[0014]
The beverage container with a straw of the present invention is not limited to the illustrated embodiment in which the beverage is filled in advance, and may be implemented in a form in which the user puts the beverage and uses it. In this case, the mouth 7 of the container body 1 may be formed in a bottle neck shape with a thread, for example, which is frequently used in the mouth portion of a bottle, and a cap with a screw may be attached to the mouth portion of the bottle neck shape. Good. Then, in order to enable the injection of the beverage, for example, as shown by an imaginary line in FIG. 7, an injection port 19 with a screw cap may be provided.
[0015]
FIG. 10 is a front view of the upper part of the container showing another embodiment of the present invention. In this embodiment, a cylindrical plug member 20 made of a hard plastic material is fixed to the outer straw 12 of the straw structure. The plug member 20 is adhered to the mouth member 7 of the container body 1 at the time of manufacturing the container. In other respects, it has the same configuration as the above-described embodiment.
