TECHNICAL FIELD The present invention relates to a refill container.

[0002]

2. Description of the Related Art In recent years, the disposal and disposal of plastic products have become various problems, and it has been demanded to reduce the amount and volume of plastic products as much as possible. As a result, various types of refill containers have come to be used. In general, these refill containers have a cylindrical body, a container body having an upright mouth and a neck via a shoulder, and a detachably screwable screw to the mouth and neck. It takes a simple form consisting of a worn cap and its thickness is made as thin as possible to reduce the weight and bulk at the time of disposal.

[0003]

These refilling containers have a body portion that is as thin as possible, so that when the cap is opened, the container body portion that is grasped is deformed so as to be dented and overflows. There is a danger of starting.

In view of the above points, the present invention has sufficiently responded to the demand that the contents can be prevented from overflowing when the cap is attached and detached, that the structure is simple and that the container can be obtained at low cost as a refillable container. Is proposed.

Another object of the present invention is to provide a container having an advantage that the user can easily confirm that the container is unused.

[0006]

According to a first aspect of the present invention, there is provided a container according to the first aspect of the present invention, comprising: a container body having a mouth and neck portion rising from a thin bottomed cylindrical body portion via a shoulder portion; , Mouth and neck 6
A container comprising a top wall 8 extending from an upper end edge of a peripheral wall 7 fitted to the outer periphery and a top wall 8 for closing an upper opening of a mouth and neck portion, and a cap 3 detachably fitted therein. The mouth and neck portion is formed in a vertically long shape, and a rigid short cylindrical holding ring 9 is fitted and fixed to the outer peripheral portion of the mouth and neck portion to constitute a refill container.

Further, in the container according to the present invention, the upper end of the holding ring 9 and the lower end of the cap peripheral wall 7 are integrally connected by a cuttable connecting portion A. It was constituted as.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. The refill container 1 of the present invention includes a container body 2 and a cap 3. The container body 2 is formed of a synthetic resin or the like, and has a mouth-and-neck portion 6 erected from the upper end of a thin-walled cylindrical body 4 having a bottom via a shoulder portion 5. The thickness of the body 4 can be the thickness used in a conventional thin-walled container of this type, but the shape retention when the liquid is stored is taken into consideration by considering the type of resin forming the container. It is good to form as thin as possible within the range that can obtain.

The cap 3 is also made of synthetic resin or the like, and has a lower end opening formed by extending a top wall 8 for closing the upper end opening of the mouth and neck from an upper end edge of a peripheral wall 7 fitted to the outer periphery of the container body and neck 6. It has a cylindrical shape. The fitting and locking means of the cap 3 with respect to the mouth and neck 6 may be screwed as shown in the illustrated example, or may be in the form of being fitted and locked by the overlying engagement of the ridges. The fitting and locking method used in the seed container can be adopted.

According to the present invention, in the above-described refilling container, the mouth and neck portion below the cap fitting portion is formed in a vertically long shape, and the rigid short cylindrical gripping ring 9 is provided on the outer peripheral portion of the mouth and neck portion. Fitted and fixed.

The length of the vertically elongated neck portion below the cap fitting portion may be such that the portion can be grasped from both sides with at least two fingers.

The gripping ring 9 is fitted and fixed in a belt shape surrounding the outer periphery of the lower part of the mouth and neck portion 6. By selecting the material and the thickness of the gripping ring 9, the gripping ring 9 is provided with such rigidity that it is not deformed even if it is gripped by a finger. By providing the grip ring 9, when removing the cap 3 by grasping this portion with two fingers, the inconvenience that the container body 2 is dented and the stored liquid overflows does not occur. You can do it.

In the embodiment shown in FIG. 1, a screw 10 is provided around the upper periphery of the neck 6 of the container body, and a pair of locking ridges 11 project from the lower periphery of the neck 6 of the container at intervals. In addition, a grip ring 9 having engaging ridges 12 engaging with the locking ridges 11 on the upper and lower inner peripheral surfaces is fitted and fixed from above the mouth and neck. Also, as shown in the illustrated example, on the outer peripheral surface of the grip ring 9,
Non-slip irregularities may be provided.

When the container of this embodiment is used, for example, if the outer surface of the grip ring 9 is gripped with two fingers and the cap 3 is screwed off, the gripping force of the container body 2 is absorbed by the grip ring. The lid can be opened without inconvenience such as the container body being dented. Then, for example, if the grip ring portion is gripped with two fingers, and the other palm is applied to the bottom of the container body to tilt the container body,
This can be done without digging the container when pouring.

The gripping ring is not limited to the case in which it is fitted to the outer surface of a ridge protruding from the outer periphery of the mouth and neck of the container body as in the above embodiment. For example, the diameter of the lower portion of the mouth and neck is reduced to such an extent that the screw escapes. It is also possible to form it with a slightly larger diameter and to closely fit it directly on its outer surface.

The embodiment shown in FIGS. 2 to 4 shows an example in which the upper edge of the grip ring 9 and the lower edge of the cap peripheral wall 7 are integrally connected by a breakable connection portion A. . The connection portion A that can be broken can adopt various forms, and can adopt a structure that can be relatively easily broken when the cap is horizontally rotated with the grip ring fixed, for example, integrally connected by a thin piece. Alternatively, they can be formed by integrally forming the two and providing perforations at the boundary portions.

In this embodiment, the cap 3 and the gripping ring 9 are integrally formed of a synthetic resin, the gripping ring 9 is formed to have a slightly larger diameter than the cap peripheral wall 7, and the lower end of the outer periphery of the cap peripheral wall 7 is formed. The portion and the upper end of the inner periphery of the grip ring 9 are connected by a plurality of thin rods 13 in the circumferential direction as a breakable connection portion A. Further, an engaging ridge 12a protrudes from the upper part of the inner peripheral surface of the gripping ring 9, and the inner surface of the lower end portion thereof is enlarged in diameter via a downward step portion 14.

Further, a pair of locking projections 11a, 11a having a large projection width are protrudingly provided below the thread at the lower part of the outer periphery of the mouth and neck.
The inner peripheral surface of the grip ring 9 is fitted to the outer surface of each locking ridge 11a while the cap peripheral wall 7 is screwed from above the mouth and neck 6, and the engaging ridge 12a is moved over the lower surface of the upper locking ridge 11a. At the same time, the downward step 14 is abutted and locked on the upper surface of the lower locking ridge 11a.

In the case of using the container of the present embodiment, if the operation of gripping the outer surface of the holding ring 9 and screwing out the cap 3 is performed, each thin rod piece 13 is broken and only the cap 3 becomes the container body 2.
It is configured to deviate from

[0020]

As described above, in the refill container of the present invention, the mouth and neck portion below the cap fitting portion is formed in a vertically long shape, and a rigid short cylindrical gripping ring is fitted around the mouth and neck portion. When the cap is attached and detached, the cap can be attached and detached without inconvenience such as overflowing of the liquid in the container body by holding the outer surface of the holding ring when attaching and detaching the cap, so that the liquid can be smoothly refilled.

In addition, as compared with the conventional container, the mouth and neck portion is configured to be slightly longer and the number of small grip rings is increased, so that the manufacturing is not so complicated, and the increase in material cost is small. The demand for this type of container that can be manufactured at low cost can be sufficiently satisfied.

Also, the upper end of the holding ring and the lower end of the cap peripheral wall are integrally connected by a breakable connecting portion, so that the cap and the holding ring can be fitted together conveniently. In a state where the connecting portion is not cut, it has an advantage that it can be easily determined that the container is unused.
