Abstract

PROBLEM TO BE SOLVED: To obtain a screw-cap container wherein a beverage can be directly taken from a container mouth without a sense of incongruity applied to lips, the container can be resealed even if there is a residual, a content liquid do not stick to a thread due to dripping after the highly viscous content liquid is filled and discharged, and the drip if any can be cleanly wiped off. SOLUTION: In the screw-cap container having a thread on an outer periphery of the container mouth to allow a cap to be screwed with, the thread 3 is notched within a range of approximately a third of the outer periphery of the container mouth under a condition that 50/D<=θ<=140/D is satisfied (where D is an outer diameter of the container mouth in mm, and θ refers to a circular arc angle in radian). Then a flat unthreaded notch 5 is provided on the outer periphery of the container mouth.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap screw-type container, and more particularly to a cap screw-type container having a screw-cap which is screwed into a cap.

[0002]

2. Description of the Related Art Conventionally, a glass cup-shaped wide-mouthed container is filled with sake or the like and sealed, and a container in which a liquid content is directly drunk from the container is widely distributed. In such a container, a screw for attaching a lid is not formed on the outer peripheral surface of the mouth so as not to cause a sense of incongruity when drinking with the lips touching the mouth of the container. Only a ring-shaped convex portion is provided, and the structure is pleasant. The corresponding cap has a structure in which a breakable score is given to the skirt wall of the aluminum lid, and the skirt wall is tightly mounted by winding the skirt wall around a ring-shaped convex portion. By breaking the fastening portion (skirt wall) from the score, the lid and the container opening are released. Therefore, there is a disadvantage that the lid cannot be reused after opening, and cannot be resealed even if leftovers occur.

In order to enable resealing, it is conceivable to screw the wide-mouthed container and the cap with a screw. However, if a screw is formed on the outer periphery of the mouth of the container, the screw thread hits the lips and gives an uncomfortable feeling. And it has hardly been used conventionally. For this reason, in a wide-mouthed container in which beverages are conventionally taken directly from the mouth of the container, the resealability is sacrificed to improve the contact of the mouth of the container with the lips when drinking, or the mouthfeel when drinking directly is reduced. At the expense of forming a screw to allow reseal, a container designed to satisfy both is not provided.

In addition to a wide-mouthed container in which a drink is directly taken from the bottle mouth, in the case of a container with a screw, if the content solution is poured directly from the bottle mouth without attaching an inner plug or a cap, the content solution is cut off. If the viscosity of the sauce or the like is high, the content liquid adheres to the screw portion after pouring, and is unsanitary. Also,
There is a drawback that it cannot be wiped clean because there is a screw even if you try to wipe it off.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention is to solve the above-mentioned drawbacks of the conventional container,
Especially in wide-mouthed containers such as wide-mouthed bottles, when drinking directly from the mouth of the container, it can be drunk without causing discomfort to the lips, and can be resealed even if leftovers occur, and filled with high viscosity liquid In the cap screw-type container, the content liquid does not stick to the screw portion due to dripping at the time of pouring, and a cap screw-type container having a mouth portion that can be wiped clean even if there is a dripping. The purpose is to provide.

[0006]

According to the present invention, there is provided a cap screw type container according to the present invention, wherein a screw is provided on an outer periphery of a container mouth so that a cap can be screwed into the cap screw type container. Within the range of approximately 1/3 of the outer periphery of the container opening and θ ≧ 50 / D (where D is the outer diameter of the container opening m
m and θ are notched so as to satisfy the condition of a circular arc radian of the screw cutout, and a screw cutout having no screw is provided on the outer periphery of the container mouth. The cap screw type container is suitable as a drinkable resealable container in which the content liquid is directly drunk from the container, and in this case, the screw cutout portion serves as a lip pad. Further, the cap screw-type container is also suitable as a resealable container for pouring a high-viscosity content liquid for discharging a high-viscosity content liquid, in which case the screw cutout portion serves as a content liquid discharge section. To

[0007] The cap screw type container of the present invention comprises:
It is more preferable that the screw notch portion is a wide-mouthed container that satisfies the condition of 50 / D ≦ θ ≦ 140 / D within approximately one-third of the outer periphery of the container mouth and that the outer diameter of the mouth portion is 30 mm or more. desirable. Particularly, it is suitable for a container having a mouth outer diameter of 40 mm or more. In this embodiment, the screw is formed in one or more turns, and the screw notch 5 is provided over the entire axial direction. However, when the screw is formed in a plurality of turns in the axial direction, the screw notch 5 It is also possible to cut out only the upper screw in the axial direction.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. The drawings show an embodiment of a resealable drinking container comprising a wide-mouth glass bottle in which a beverage content liquid such as sake can be drunk directly from the container. In the drawing, reference numeral 1 denotes a container body, and 2 denotes a container mouth. The outer diameter of the container mouth 2 is large enough to be able to be drunk with the mouth of the container sandwiched between the lips in the usual form for beverages, and approximately 1 to 2.5 around the outer periphery.
A winding screw 3 is formed. As shown in FIG. 1, the screw 3 has a threaded portion 4 formed with a normal thread and a thread notched in the middle of the screw so that no thread is present in a portion where the lip contacts. And a screw notch 5. The screw notch 5 is used as a lip pad for drinking beverage directly from the container.

The size of the screw notch 5 varies depending on the outer diameter of the mouth of the container, and is not particularly limited. However, the size of the screw notch 5 is larger than a range in which the screw thread does not hinder the drink, and the lid is inclined when the lid is screwed. It must be in the range that can be screwed well. Of these conditions, the range of the screw notch is defined as the range in which the screw thread does not hit the lips,
(Mm) and the notch arc angle θ (radian)
It is desirable that 50 / D ≦ θ ≦ 140 / D is satisfied. And in order to drink by directly putting the lips on the container mouth, it is desirable that the container mouth diameter D is a wide mouth container having a diameter of 30 mm or more. If the arc angle θ is smaller than 50 / D, it is not possible to secure a sufficient size for the lip contact portion. Also, 14
If it is larger than 0 / D, the range of the screw cutout portion becomes too large and becomes unstable when the lid is attached. A more desirable range is 6
0 / D ≦ θ ≦ 120 / D, and the aperture is 40 mm or more. Further, in order to ensure that the lid can be screwed without tilting when the lid is screwed even if it has a screw notch, and that the sealing property can be reliably maintained even after the screwing, an experiment by the present inventor has been conducted. It has been confirmed that the screw notch should be within the range of 1/3 of the entire circumference of the screw.

In the embodiment shown in FIG. 1, the outer diameter D of the mouth of the container body is 45 mm, and the arc angle θ of the thread cutout is 12 mm.
It is formed at 0 °. Therefore, the screw cutout has an arc length of about 47 mm, and when the drink is put on the screw cutout with the lips in contact, the lips do not touch the screw portion, and the drink can be taken without discomfort like a conventional lid-tight container. be able to. Then, in the case where a drink is left behind, the cover can be resealed by screwing and attaching the lid again, so that the lid can be carried and stored, and the drawbacks of this type of conventional container can be solved.

In the above embodiment, the screw formed in the container opening is a single screw, but the screw is not limited to a single screw and may be a multi-thread screw such as a double screw, but 1.5 or more turns are required. desirable. Further, the cap 10 corresponding to the container is provided with one or multiple full-circle screws in accordance with the screws at the container opening. By employing a cap having a screw around the entire circumference, even if there is a screw notch in the mouth of the container, the screw can be smoothly screwed together without the need to position the lid when the lid is mounted. FIG. 2 shows a state where the cap 10 is screwed.

The container according to the present embodiment is configured as described above. By forming the screw notch in the above-described range, even if the container has the screw notch, there is no problem in mounting the lid. Can be installed without any problem. The sealing of the container is achieved by the close contact between the top of the container opening and the sealing material provided inside the top surface of the lid, so that the sealing is not impaired even if there is a screw notch.

In addition, the present invention is not limited to a container for directly drinking a content liquid, but is applied to a resealing container for discharging a high-viscosity content liquid such as a high-viscosity seasoning liquid such as pork cutlet sauce. An excellent container can be obtained. That is, since the mouth of the container of the present invention is a container to which a lid is screw-mounted, but has a screw cutout in a predetermined range, by pouring the content liquid from the screw cutout, the content liquid is poured out. Will not stick to the screws and become unsanitary. Also, even if the content liquid adheres to the screw notch, it can be easily wiped clean because it has no screws and has a flat surface.
You can always keep it clean. In addition, the resealable container for discharging the high-viscosity content liquid is not necessarily a wide-mouthed container, and can be applied to a container having an arbitrary diameter.

In the above embodiment, the case where the cap screw-fit type container is applied to a glass bottle is shown. However, the present invention is not limited to a glass bottle, and the material such as a plastic bottle is not particularly limited. The material of the cap applied to the container is not limited, and it may be made of plastic or metal. Furthermore, the shape of the container is not limited to the above embodiment, and any shape can be adopted.

Although the above embodiment does not have a tamper-evident function for judging the presence or absence of unauthorized opening at the distribution stage, a tamper-evident band is provided at the lower end of the skirt wall of the cap. It is also possible to provide by means of a weakening line. In this case, it is necessary to form a jaw below the mouth of the container body with which an engaging portion such as an engaging fin formed on the tamper-evident band is engaged. By forming so that the entire circumference is reduced in diameter, when drinking directly from the container, the lips do not feel uncomfortable even if the lips hit the jaws, and even if the contents liquid adheres to the jaws when the contents liquid is poured out Since it can be easily wiped off, there is no problem in achieving the above object. Thus, by providing a tamper-evidence band on the cap, the resealable wide-mouth container, which conventionally had the tamper-evidence function by wrapping the entire mouth portion with a plastic film or the like, is similar to the narrow-mouth container. The tamper-evidence function can be provided only by mounting the.

[0016]

As described above, according to the cap screw-type container of the present invention, when drinking a beverage directly from the container mouth, it is possible to drink without giving an uncomfortable feeling to the lips, and to reseal even if unreserved drinking occurs. can do. In addition, the cap screw-type container that fills the high-viscosity content liquid does not stick to the screw part due to dripping after pouring, and it is sanitary because it can be wiped clean even if there is dripping afterwards. The disadvantages of the conventional cap screw type container can be eliminated.
