Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention is a container such as a can filled with a drink such as youth, which can be used for drinking by taking out a straw from the container when the container is opened. This invention relates to a beverage container with a built-in straw.

``Prior Art'' Conventionally, when drinking a drink filled in a can, it was unsanitary to touch the rim of the can, which is exposed to the outside and easily gets dirty. For this reason, various can containers with built-in straws have been proposed.

FIG. 10 shows a beverage container with a built-in straw proposed in Japanese Utility Model Application Publication No. 55-40743.
This container is constructed by fixing a locking piece 5 to the lower surface of a cutout piece 4, which is surrounded by a cut line and can be cut off from one end, provided on the top lid 2 of an airtight beverage container 1. The upper end of a flexible straw 6, which is longer than the depth of the container, is secured to the piece 5.

According to this container, when the cutout piece 4 of the container 1 is cut out and the container is opened, the upper end of the flexible straw 6 that is locked to the locking piece 5 of the cutout piece 4 is pulled out from the container 1, so that the straw 6 can be used to gulp the beverage in the container.

"Problems to be solved by the invention" Regarding the above-mentioned conventional beverage container with a built-in straw,
After assembling the body 7 and the top lid 2, the flexible straw 6 must be loaded and then filled with the liquid content, after which the bottom lid 8 must be seamed.

For this reason, the conventional beverage container with a built-in straw has to be of a type in which the bottom lid 8 is attached last, and cannot be used in so-called two-piece cans in which the body 7 and the bottom are integrally formed. It was hot.

In addition, in the above conventional container, the flexible straw 6
When loading the straw 6, the tip of the straw 6 must be locked to the locking piece 5 of the top lid 2, and the straw 6 must be bent and compressed. There was a problem in which the liquid filling speed (600 to 800 bottles/min) could not be achieved.
Furthermore, since the straw 6 was made up of one piece, it was difficult to drink all the contents.

"Means for Solving the Problems" The beverage container with a built-in straw of the present invention has a container body that has a rotating body-shaped hollow part that accommodates the liquid content.
A beverage container with a built-in straw, in which a two-stage straw is movably held toward the container mouth by a straw insertion hole provided in a holding member having a specific gravity lower than the content liquid, wherein the container mouth includes: A lid portion that closes a hollow portion of the container body is formed so that a central portion thereof can be opened, and the straw insertion hole is arranged such that the holding member is located under the central portion of the container lid portion. The upper member is formed by a perforated upper member and the leg portions extending downward from the upper member, and the upper member is formed in a size that fits loosely in the vicinity of the lid of the container body, and the leg portions are formed to fit loosely into the vicinity of the lid of the container body. The two-stage straw is configured to be expandable by an inner tube and an outer tube, and one end of each of the inner and outer tubes is provided so that it fits loosely within the main body. An engaging portion is provided to prevent separation of the inner and outer tubes, and the tube remaining on the bottom side of the container when the container is expanded after opening the container has a size to be engaged with the straw insertion hole of the holding member. The straw is characterized by being provided with a protrusion of low specific gravity that allows the straw to float above the liquid inside.

``Operation'' When the container is opened, the two-stage straw flies out from the container mouth due to buoyancy through the straw insertion hole provided in the holding member that floats toward the container mouth and is loosely stored. When you pull out either the inner or outer tube of this two-stage straw, the locking protrusion provided at the lower end of the other tube locks on the lower surface of the holding member, and the two-stage straw Extended. This extended straw can be used to gulp down the entire drink inside the container.

"Example" Example 1 FIG. 1 shows an example of the present invention, and reference numeral 11 in the figure is a container body. This container body 11
This is a so-called two-piece can container, and the body portion 11a is formed into a cylindrical shape with a bottom 11b. The upper opening of the body portion 11a is closed by a lid member 11c. The hollow portion 11d in which the liquid content of the container body 11 is accommodated is formed into a cylindrical shape, which is a type of rotating body. As shown in FIG. 2, the lid member 11c has an opening 15 formed by a cutout piece 13 surrounded by a score 12 so as to be openable. A tension ring 14 is attached to the cut-out piece 13, and by pulling the tension ring 14 and removing the cut-out piece 13, the opening portion 1 is removed.

is provided so as to open including the central portion of the lid member 11c. That is, the mouth portion 15 is provided so as to open to include a portion of the hollow portion 11d of the container body 11 through which the rotation center axis D passes.

A holding member 18 holding a two-stage straw 16, which will be described later, is housed within the container body 11. The holding member 18 is made of synthetic resin, such as polyethylene, and has a specific gravity lower than that of the liquid contained in the container.

The holding member 18 is attached to the hollow portion 11 of the container body 11.
d is formed to have an external shape that is loosely inscribed at least in the vicinity of the lid member 11c. As shown in FIG. 3, this holding member 18 includes three rings 18 with different diameters.
a, 18b, 18c are concentrically fixed by three radially extending bridges 18d, and three legs 18e extending downward are connected to the lower surface of the outermost ring 18c of the upper member. It has a similar shape. The diameter of a virtual circle formed by connecting the outer surfaces of the legs 18e of the holding member 18 and the outer diameter of the outermost ring 18d are set to be slightly smaller than the inner diameter of the hollow portion 11d of the container body 11.

In the container of this example, the hollow portion 11d is formed in a cylindrical shape, so that the holding member 18 is movable within the container body 11 along the inner surface thereof. Further, this holding member 18 is prevented from being reversed within the container body 11 by the legs 18e. the result,
As will be described later, when the content liquid is injected into the hollow part 11d during container manufacturing, the holding member 18 is held in the hollow part 11d.
It is designed to levitate approximately along the central axis of the plane.

A straw insertion hole 18f is formed in this holding member 18 by an inner ring 18a. This straw insertion hole 18f holds a two-stage straw 16, which will be described later, so that it can move toward the mouth 15 of the container body 11. The inner diameter of this straw insertion hole 18f is the outer tube 1 of the straw 16, which will be described later.
The dimensions are set such that 6a can be loosely fitted. This straw insertion hole 18f allows the holding member 18 to
1, so that it is located under the mouth part 15 of the container when it is loosely stored near the lid member 11c of the hollow part 11d of 1.
It is formed in the center of the holding member 18.

As shown in FIG. 4, the two-stage straw 16 consists of an outer tube 16a and an inner tube 16b slidably inserted into the outer tube 16a. The lower end of the outer tube 16a is reduced in diameter to the extent that it touches the outer surface of the inner tube 16b, forming a separation prevention engagement portion (outer) 16f.
It is said that In addition, this separation prevention engagement part (outer)
A check stopper 16c that protrudes inward is formed slightly above 16f. Further, a flange 1 is provided at the upper end of the outer tube 16a and protrudes outward.
6d is formed. This flange 16d prevents the straw 16 from falling out of the straw insertion hole 18f of the holding member 18, and is formed larger than the inner diameter of the straw insertion hole 18f.

Further, at the upper end of the inner tube 16b, when the two-stage straw 16 is extended, the inner and outer tubes 16a, 16 are engaged with the separation prevention engaging portion (outer) 16f.
A separation prevention engaging portion (inner) 16e is formed to prevent separation of the straw 16 and to maintain the extended state of the straw 16 by engaging the non-return stopper 16c.
A locking protrusion 16g is formed at the lower end of the inner tube 16b to prevent the straw 16 from falling out of the straw insertion hole 18f of the holding member 18. The outer diameter of the locking protrusion 16g is larger than the inner diameter of the straw insertion hole 18f of the holding member 18, and when the two-stage straw 16 is extended, the outer diameter of the locking protrusion 16g is larger than the inner diameter of the straw insertion hole 18f of the holding member 18. It is locked to the outer edge to prevent the straw 16 from falling off from the holding member 18.

The two-stage straw 16 of the container in this example is formed to have a specific gravity that allows it to float above the liquid content when the container is opened.

The two-stage straw 16 of this example is constructed by forming the locking protrusion 16g of the inner tube 16b from a material with low specific gravity so that the locking protrusion 16g also has a float function. It is designed to be able to float on liquid. The locking protrusion 16g of the two-stage straw 16 is made of a material with a small apparent specific gravity, such as foamed urethane, foamed polystyrene, foamed polyethylene, and foamed polypropylene.

This beverage container with a built-in straw is manufactured as follows. First, a "straw assembly" in which the two-stage straw 16 and the holding member 18 are assembled is manufactured in advance. Then, the above-mentioned "straw assembly" is put into the body 11a of the container body 11 that is being transported to the step of filling the container with the liquid, and then the liquid is filled. When the content liquid is injected, the holding member 18 formed to have a specific gravity lower than that of the content liquid is attached to the body 1 of the container body 11.
It floats along the inner surface of 1a. At this time, the holding member 18
The straw insertion hole 18f rises almost along the central axis of the cylindrical container body 11, and the two-stage straw 16
is held approximately along the central axis of the container body 11.

After the liquid content is injected into the body 11a of the container body 11 as described above, the lid member 11c is seamed to the body 11a to seal the container body 11. In this way, a drink container with a built-in straw filled with the liquid content is manufactured.

The upper end of the straw held by the holding member 18 in the container body 11 is attached to the lid member 1.
It is located below the mouth part 15 of the container, which is provided to open including the central part of the container 1c.

To drink the liquid contained in this beverage container with a built-in straw, first, open the mouth portion 15 by pulling the cutout piece 13 of the lid member 11c. When the opening 15 is opened to the center of the lid member 11c, the unexpanded two-stage straw 16 pops out from the opening 15 due to buoyancy. When the outer tube 16a of the straw 16 that has protruded is pulled, the locking protrusion 16g at the lower end of the inner tube 16b of the straw 16 locks onto the holding member 1, as shown in FIG.
8, the straw 16 can be extended. At this time, the holding member 18 resists the force that stretches the straw 16 by its own specific gravity and strength or by coming into contact with the lower surface of the lid member 11c of the container body 11.

Since the extended straw 16 is sufficiently longer than the depth of the container, the user can drink without leaving the contents of the container.

According to this beverage container with a built-in straw, since the straw 16 is provided with the protrusion 16g having a low specific gravity, the buoyant force applied to the straw 16 can be made sufficiently large. Therefore, according to this beverage container with a built-in straw, the floating speed of the straw 16 after opening the container can be sufficiently increased, and it is possible to prevent the consumer from becoming anxious when opening the mouth portion 15 of the container.

In addition, in this beverage container with a built-in straw, the holding member 18 is provided with legs 18e that fit loosely within the container body 11.
When the leg 18e is tilted greatly against the container body 1, the leg 18e
1 and restricts the inclination of the holding member 18.
As a result, the posture of the holding member 18 with respect to the container body 11 is stabilized, and the position of the straw insertion hole 18f is always maintained at the center portion where the container mouth portion 15 is formed. Therefore, according to this beverage container with a built-in straw,
When you open the container to drink the contents, straw 1
Mouth part 1 opened immediately without 6 getting caught
5, so this container also prevents consumers from getting irritated when opening the container.

In addition, in this beverage container with a built-in straw, the upper member consisting of the ring 18c and the legs 18e of the holding member 18 are formed to fit loosely into the container body 11, so when manufacturing this container, the straw 16 is not attached. It is sufficient to simply throw the holding member 18 into the container body 11. Therefore, according to this beverage container with a built-in straw, the filling speed of the contents of the can container can be maintained even when the straw 16 is loaded.

Note that the beverage container with a built-in straw of the present invention is not limited to the above embodiments. For example, in the above embodiment, a container is shown in which the straw 16 is extended by pulling out the outer tube 16a of the two-stage straw 16, but the beverage container with a built-in straw of the present invention has an inner tube 16b.
It is also possible to extend the straw 16 by pulling it out. In that case, the tube remaining on the bottom side of the container during expansion becomes the outer tube 16a.

Furthermore, in the container of the first embodiment, when opening the container mouth 15, it is sufficient that the container mouth 15 is formed up to the center of the lid member 11c, and it is not necessary to completely cut out the cutout piece 13. That is, the end of the cut piece 13 may be connected to the lid member 11c.

"Effects of the Invention" As explained above, by using the beverage container with a built-in straw of the present invention, the straw can be easily and instantaneously loaded into the container body via the holding member.

In addition, the beverage container with a built-in straw of the present invention has a two-tiered straw that pops out at the same time as the container is opened.
By simply pulling out the inner tube or outer tube of this straw, the straw is extended and becomes a straw with sufficient length, allowing the user to drink up to the liquid content at the bottom of the container. Therefore, according to the present invention, it is possible to provide a drink container with a built-in straw that is easy to handle even for first-time customers.

Furthermore, since the beverage container with a built-in straw of the present invention is formed so that the holding member can float, the holding member holding the straw is always located at the top of the container after the content liquid is contained, and the container opening Since the portion includes the center portion of the lid portion and is openable, and the straw is positioned under the center portion of the lid portion, the straw is held by the holding member regardless of the orientation of the container mouth portion during manufacturing. A straw can be loaded into the container.

Therefore, in the beverage container with a built-in straw of the present invention, the straw can be loaded into the container before seaming the lid member. That is, the lid member can be attached last.

Therefore, according to the present invention, it is possible to provide a beverage container with a built-in straw, such as a two-piece can in which the body and the bottom are integrally formed, with a built-in straw.

In addition, according to the beverage container with a built-in straw of the present invention, the following effects can be obtained.

Since the protrusion with low specific gravity is provided on the straw, the buoyancy force applied to the straw can be sufficiently increased. Therefore, according to the beverage container with a built-in straw of the present invention, it is possible to sufficiently increase the floating speed of the straw after the container is opened, and it is possible to prevent a situation in which the consumer becomes impatient when opening the container.

In addition, in the beverage container with a built-in straw of the present invention, the holding member is provided with legs that fit loosely into the container body, so if the holding member is tilted significantly with respect to the container body, the legs will collide with the container body, causing the holding member to Regulates the inclination of members. As a result, the posture of the holding member relative to the container body is stabilized, and the straw insertion hole is always kept at the center of the container lid where it is opened. Therefore, according to the beverage container with a built-in straw of the present invention, when the container is opened to drink the contents, the straw immediately pops out from the opening without getting caught.
In this respect as well, this container can prevent consumers from becoming impatient when opening the container.

In addition, in the beverage container with a built-in straw of the present invention, the upper member and the legs of the holding member are formed to fit loosely into the container body, so when manufacturing this container, the holding member with the straw attached is attached to the container.
