Description

The present invention relates to a lidded container formed by sealing a container by plugging a cap into the mouth of the container, and more specifically, an engaging portion for sealing a cap projecting outward from the outer peripheral edge of the mouth of the container. Even without
The container and the cap are securely sealed, and when opening the cap, the cap is smoothly opened simply by turning the outer circumference of the cap counterclockwise, and the container is closed on the outer periphery of the container mouth. The present invention relates to a container with a lid that can drink a drink with a good mouthfeel as if it were a drink with a cup because there is no locking portion protruding in the direction.

As a conventional container with a lid, for example, a container in which a cap that can be easily opened is sealed at the mouth of a glass wide-mouth container containing 180 cc of sake. This container with a lid is widely distributed because it has a wide mouth and is convenient for drinking drinks such as sake. However, this lidded container is required to have a contradictory function that the stoppering and sealing operation is surely performed and can be easily opened. For example, the container described in Patent Document 1 is known. ing.
Japanese Patent Application Laid-Open No. 6-211260

As shown in FIGS. 6 and 7, the container with a lid according to Patent Document 1 is formed by sealing a cap 52 made of a thin metal plate on a mouth portion 51 of a cup-shaped container 50. The top wall 53, the skirt wall 54 depending from the periphery thereof, and the gripping piece 55 extending from the lower end of the skirt wall 54 are included. The skirt wall 54 is formed with a plurality of fracture lines 56 each having a notch 56a and a slit 56b that extends in the axial direction at a predetermined interval in the circumferential direction. Reinforcing deformation 57 extending in the direction
Is formed.

Since the container with a lid of the above-mentioned patent document 1 has the reinforcing deformation portion 57, the skirt wall 54 of the cap 52 is not deformed, and the work of sealing the cap 52 to the mouth portion 51 of the container 50 is facilitated. Since the sealing holding property is also ensured and the increase in the opening force due to the presence of the reinforcing deformation portion 57 is slight, the simple opening property can be ensured.

However, the container with a lid of the above-mentioned patent document 1 has a conflicting function that it can be easily opened even though the stopper sealing work can be easily performed and the sealing retention property is reliable, but it is a cup-shaped container. 50, since a ball edge 58, which is a protrusion for sealing and holding, is formed on the outer peripheral surface of the upper end of the mouth 51, when drinking sake such as sake after opening the cap 52, the ball is inevitable. There is a problem that the edge 58 hits the mouth and it is difficult to drink sensuously. However, if the ball edge 58 on the outer peripheral surface of the upper end of the container mouth portion 51 is eliminated, it is impossible to ensure the sealing retention.

Therefore, an object of the present invention is to provide a container with a lid that is easy to fit and seal, and that can be easily opened and sealed, while being easy to drink beverages sensuously. There is to do.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.

An inner ring that hangs in close contact with the inner peripheral surface of the container mouth part hangs down on the inner surface of the top wall, and further on the inner side, it corresponds to the inclined cam. A rib is provided at the position where the cap is turned in the opening direction, so that the rib can interfere with the inclined surface of the inclined cam and the cap can be opened from the container mouth. A lidded container is provided.

Moreover, according to this invention, the said container with a lid | cover which does not have a projection part in the outer peripheral edge part of the opening part of the said container is provided.

Further, according to the present invention, the inner surface of the container mouth portion includes an upper inner peripheral surface in close contact with the inner ring, a first step portion extending inward from a lower end of the upper inner peripheral surface, and the first step An intermediate inner peripheral surface extending downward from the intermediate portion, a second step portion extending inward from the intermediate inner peripheral surface, and the lidded container in which the inclined cam is formed in the second step portion. Provided.

Further, according to the present invention, the axial height (H) between the highest and lowest positions of the inclined cam is the maximum of the outer peripheral surface of the inner ring from the top wall inner surface of the cap at the mouth of the container. The above-mentioned lidded container is provided which is larger than the axial length (L) to the outer diameter part.

The container with a lid of the present invention remains sealed when the cap, which is fitted between the skirt wall and the inner ring and sealed in the container mouth, is turned in the opening direction (counterclockwise). The cap slides on the container mouth, the rib of the cap hits the inclined surface of the inclined cam provided on the container mouth, and further slides on it, and the cap rises by the rib according to the inclined surface of the inclined cam The container is gradually separated from the container mouth and finally unplugged from the container mouth. Therefore, since the container mouth portion is more closely fitted and sealed between the skirt wall and the inner ring, the structure of the container mouth portion for sealing is increased, and the beverage can be formed in a shape that allows the beverage to be sensually drinkable. On top of that,
The plug sealing operation is easy and the sealing and holding property is reliable, and there is an effect that it can be easily opened.

In addition to the above effect, the container with a lid of the present invention can attach a mouth without hitting the protrusion at the outer peripheral end of the container mouth when the beverage in the container is taken after opening the cap. In particular, there is an effect of sensuously making it easy to drink beverages.

In the container with a lid of the present invention, the upper inner peripheral surface of the container mouth portion is in close contact with the inner ring to ensure hermetic retention, and the inclined cam of the second step portion interferes with the rib of the cap so that it can be easily opened. Is secured. Therefore, in addition to the above effects, by clarifying the role of sealing and retaining properties and simple opening on the container side, there is an effect of making these roles more reliable.

Further, in the container with a lid of the present invention, the cap is rotated in the opening direction, the cap is lifted by the rib according to the inclined surface of the inclined cam, and the maximum outer diameter portion of the outer peripheral surface of the inner ring is set from the upper end surface of the container mouth portion. If the cap is raised to the top, it can be removed and opened from the container mouth by a slight external force.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

1 is a longitudinal sectional view of a container with a lid showing an embodiment of the present invention, FIG. 2 is a plan view of the container in the container with a lid of FIG. 1, and FIG. 3 is a longitudinal sectional view of a cap in the container with a lid of FIG. 4 is a bottom view of the cap of FIG. In the drawing, a container 1 with a lid is for sealing a container 2 by plugging a cap 4 into a mouth part 3 of a container 2, and an inclined cam 5 is provided on an inner wall of the container mouth part 3,
The cap 4 includes a top wall 6 and a skirt wall 7 that hangs down from the periphery of the top wall 6. An inner ring 8 that is in close contact with the upper inner peripheral surface 10 of the container mouth 3 hangs down on the inner surface of the top wall 6. Further, a rib 9 is provided at a position corresponding to the inclined cam 5 on the inner side, and by rotating the cap 4 in the opening direction, the rib 9 interferes with the inclined surface 5a of the inclined cam 5, and the container mouth portion The cap 4 can be opened from 3.

The container 2 can be filled with beverages such as liquor, milk drinks, coffee drinks, fruit juice drinks, and can be shaped so long as the cap 4 can be liquid-tightly plugged into the mouth 3 of the container 2. There is no particular limitation. The material of the container 2 is mainly synthetic resin or glass, but there is no particular limitation to this. However, from the viewpoint of easy drinking of the beverage in the container 2, it is desirable that the container mouth portion 3 is a wide mouth, and in addition, the one having no protrusion on the outer peripheral end portion 3 a of the container mouth portion 3 is particularly preferable. desirable. If there is no protrusion at the outer peripheral edge 3a of the container mouth 3, when opening the cap 4 and drinking the beverage in the container 2, the mouth is attached to the outer peripheral edge 3a of the container mouth 3 without hitting the protrusion. Since it obtains, it becomes easy to drink a drink sensuously.

And on the inner surface of the container mouth 3, there is an upper inner peripheral surface 10 in which the inner ring 8 is in close contact, a first step portion 11 extending inward from the lower end of the upper inner peripheral surface 10, and a lower portion than the first step portion 11. An intermediate inner peripheral surface 12 that extends and a second step portion 13 that extends inward from the intermediate inner peripheral surface 12 are formed. In the first embodiment, four inclined cams 5 are formed on the second step portion 13. However, the number of inclined cams is not limited thereto.

As described above, the cap 4 is plugged into the container mouth 3 to seal the container 2 and includes a top wall 6 and a skirt wall 7 depending from the periphery thereof. The inner ring 8 hangs down from the inner surface of the top wall 6, and the skirt wall 7, the inner ring 8, and the top wall 6 between them constitute a fitting part 20 with the container mouth 3. Note that the ring-shaped convex portion 2 is formed on the outer peripheral surface of the inner ring 8.
1 is formed on the inner peripheral surface of the skirt wall 7, and the ring-shaped convex portion 22 is formed on the inner peripheral surface of the skirt wall 7. Is further enhanced. In addition, the cap 4 plugged into the container mouth 3 must be rotatable in at least the opening direction in that state, and in order to assist the cap 4, the outer peripheral surface of the skirt wall 7 is not slipped. 23 is formed. The cap 4 is made of synthetic resin.

Four ribs 9 are provided on the further inner side of the inner ring 8 at positions corresponding to the inclined cams 5. When the leading end of the rib 9 is interfered by the inclined surface 5a of the inclined cam 5, the rib 9 rises according to the inclined surface 5a, and the cap 4 also rises along with it, gradually separating from the container mouth 3, and finally The cap 4 is removed from the container mouth 3 so that it can be opened. In addition, the round part 9a is provided in the front-end | tip part of the rib 9, and when it contacts and slides on the inclined surface 5a of the inclination cam 5, it goes smoothly. In this embodiment, the same number of four inclined cams 5 on the container mouth 3 side and four ribs 9 on the cap 4 side are used. However, the number is not necessarily the same, and the number may be one or more. As the shape of the inclined cam 5, for example, an inclined surface 5 a extending obliquely upward from the second step portion 13 on the plug opening direction side and a vertical surface 5 b extending downward from the upper end of the inclined surface 5 a and reaching the second step portion. Consists of.

In order for the tip of the rib 9 to come into contact with and slide on the inclined surface 5a of the inclined cam 5, and finally the cap 4 can be detached from the container mouth 3 and opened, as shown in FIG. The axial height (H) between the highest position and the lowest position of the inclined cam 5 is the maximum outer diameter portion from the inner surface of the top surface wall 6 of the cap 4 in the container mouth 3 to the outer peripheral surface of the inner ring 8, that is, the ring. It is necessary to be larger than the axial length (L) to the top surface of the convex portion 21. Thereby, the cap 4 is rotated in the opening direction, the cap 4 is raised according to the inclined surface 5 a of the inclined cam 5, and the top surface 21 a of the ring-shaped convex portion 21 on the outer peripheral surface of the inner ring 8 is moved to the container mouth portion 3. If the cap 4 is raised until it is above the upper end surface 3b, the cap can be detached and opened from the container mouth 3 with a slight external force.

Next, the use of the lidded container 1 having the above configuration will be described with reference to the drawings.
First, after the beverage is filled in the container 2, the container 2 is sealed by applying the fitting portion 20 of the cap 4 to the container mouth 3. At that time, it is necessary for the cap 4 to be able to rotate at least in the opening direction on the mouth 3 in a state where the container 2 is sealed. Can be prevented from opening.
Next, when using the beverage in the lidded container 1, if there is any packaging, the cap 4 is grasped with fingers and turned in the direction of opening, the rounded portion 9 a of the rib 9 of the cap 4 becomes the inclined surface 5 a of the inclined cam 5.
The rib 9 starts to slide at the lowest position. When the cap 4 is rotated, the rib 9 rises according to the inclined surface 5a, and the cap 4 also rises along with it, and gradually moves away from the container mouth 3, and the rib 9 reaches the highest position on the inclined surface 5a. The fact that the rib 9 has reached the highest position of the inclined surface 5 a is that the top surface 2 of the ring-shaped convex portion 21 on the outer peripheral surface of the inner ring 8 of the cap 4.
Since 1a is rising above the upper end surface 3b of the container mouth portion 3, the cap 4 can be removed from the container mouth portion 3 with a slight external force, and the opening is completed.

When the beverage remains in the container 2, the fitting part 20 of the cap 4 is applied to the container mouth part 3 so that the rib 9 of the cap 4 does not hit the inclined cam 5 of the container mouth part 3. By doing so, the container 2 can be resealed and beverage spillage and contamination can be prevented. However, considering the ease of plugging, the cap 4 may be plugged while being rotated in the closing direction, or an inclined surface in the same direction as the inclined cam 5 may be provided on the lower surface of the rib 9. This inclined surface is preferably provided substantially equal to the inclination angle of the inclined cam 5. If you want to use the beverage again, you can open it as described above.

Although the first embodiment of the present invention has been described above, it should be understood that the specific configuration is not limited to this, and that changes can be made as appropriate without departing from the scope of the present invention.

The container with a lid of the present invention can be easily used for fitting and sealing work, and its sealing and retaining properties are reliable, but it can be easily opened, and has high availability when conflicting requirements are required at the same time.
In addition, there is an extremely high possibility of use when it is desired to obtain a container that is sensually easy to drink beverages with high palatability.
