Description

  The present invention relates to a package and a spout. Specifically, a container main body provided with a storage portion for storing a storage object, a cylindrical neck portion extending outward from the storage portion and having an opening at a tip thereof and the opening communicating with the storage portion; and the opening. The present invention relates to a package including a lid for closing. In addition, for example, a cylindrical joint that can be communicated with the container by being joined to the container for containing the container, and an opening at the tip that extends outward from the joint, and the opening is the container The present invention relates to a spout comprising a spout body provided with a cylindrical neck that can communicate with a body, and a lid that closes the opening.

Conventionally, as this type of package, for example, the lid has a lid screwing portion that is screwed to the tip of the neck portion to close the opening, and the neck portion is screwed with the lid screwing portion. And the lid screwed portion and the neck screwed portion are engaged with each other, and the lid screwed portion and the neck screwed portion are screwed together. A package that is configured to be in an open state in a state where is released is used.
Such a package is configured to be in a closed state with the lid screwed portion and the neck screwed portion being screwed together, and thus has a high sealing performance. For example, the package body is accommodated in the accommodating portion. When the contained material contains a volatile component, there is an advantage that the volatile component is volatilized and the composition ratio of the contained material can be suppressed from changing.
Therefore, such a package is suitably used, for example, as a tube with a spout that accommodates a paste-like medicine (such as an ointment) as an accommodation.

However, in such a package, the lid is separated from the container body in the open state, for example,
When handling a plurality of packages having the same shape of the lid screwing portion and the neck screwing portion, each containing a different drug, and preparing the drug, the lid once attached with a kind of drug is different There is a risk of being attached to the neck of the container body that contains the medicine. And there exists a possibility that the chemical | medical agent accommodated in the other container main body may be mixed into the chemical | medical agent accommodated in one container main body through this cover.
Further, if the lid is separated, there is a possibility that the lid may be lost.

From this point of view, for example, in Patent Document 1, a container main body that contains an object and has an opening at a tip thereof, and a lid that has a lid main body that closes the opening are provided, and the container main body and the lid main body include The container body has a cylindrical lid mounting portion on the outer peripheral side proximal to the threaded portion of the container body, and the lid is mounted on the lid. There has been proposed a packaging body having a cylindrical attachment portion that is rotatably arranged around a portion and attached to the lid attachment portion, and a lid main body and a connecting portion that connects the attachment portion.
Moreover, in patent document 2, the container main body which accommodates the accommodation and has a front-end | tip opening at the front-end | tip, and the lid | cover which has a lid main body which obstruct | occludes this front-end | tip opening part are provided, The said container main body accommodates the accommodation. And an outer frame portion that accommodates the accommodating portion, the accommodating portion and the lid main body each have a threaded portion that is screwed together, and the accommodating portion is screwed into the accommodating portion. A flange part on the outer peripheral part of the base end side from the part, the flange part has an arcuate groove part in which one end is formed with a flange opening in the outer diameter part, and the outer frame part is the housing part The outer frame groove portion formed in the same shape as the groove groove portion and having an outer frame opening communicating with the outside at one end at a position that matches the groove groove portion in a state in which the lid is accommodated, and the lid includes the groove groove portion and A package having arms that are movably fitted in the outer frame groove and tiltable through the heel opening and the outer frame opening. It is draft.
Furthermore, in Patent Document 3, a container main body that contains an object and has an opening at the tip thereof, a lid that closes the opening, and a hinge portion that connects the container main body and the lid are provided, and the lid includes the hinge portion. An inner lid body that closes the opening via the inner lid, an inner lid that has a joint for joining the inner lid body and the container body, and is rotatably attached to the inner lid while surrounding the inner lid; There has been proposed a package body including an outer lid screwed to the outer periphery of the container body, and the inner lid body is hinged to the container body through the hinge portion so as to be freely opened and closed.

However, the packaging body of Patent Document 1 has a problem that the structure is complicated as a whole because the lid includes the attachment portion and the connection portion having a complicated structure in addition to the lid body. There is.
Further, the package of Patent Document 2 has a problem that the structure of the container body is complicated because the container body has the housing part and the outer frame part having a complicated structure. Further, since this arm can move only in the ridge groove part and the outer frame groove part formed in a circular arc shape, this package has a small rotation distance when screwing the housing part and the lid body, There is also a problem that the sealing performance is low.
Furthermore, the package of Patent Document 3 requires two lids, the inner lid and the outer lid, which are separately formed, and has a problem that the structure is complicated.

  Further, the conventional spout serving as the mouth portion of the package also has the above-described problems as with the package.

  Furthermore, it is desired that the package and the spout can be easily taken in and out of the package.

  In view of the above problems and demands, the present invention has a relatively simple structure in which the opening is highly sealed in the closed state, and the lid and the container main body are not easily separated even in the opened state. It is an object to provide a package that is easy to peel. In addition, the sealing property of the opening is high in the closed state, the lid and the spout body are difficult to separate even in the open state, and it is a relatively simple structure, and it is an object to provide a spout that allows easy loading and unloading of items from the opening. To do.

The present invention includes a container main body provided with a storage portion for storing a storage object, a cylindrical neck portion that extends outward from the storage portion, has an opening at a tip, and communicates the inside and the outside of the storage portion, and the opening. A lid provided with a cap-like lid body that closes, the lid body having a lid screwing portion that is screwed to a tip of the neck portion, and the neck portion is screwed with the lid screwing portion. It has a neck threaded part, and is configured to be closed by screwing the lid threaded part and the neck threaded part, and the screwing of the lid threaded part and the neck threaded part is released. A package configured to be in an open state by
The lid includes two arms extending from the lid body to the proximal end of the neck in the closed state;
Each of the two arm portions includes a support protrusion protruding inward,
The outer periphery of the neck includes an accommodation groove that accommodates the support protrusion,
The accommodation groove is formed at two locations facing each other, the longitudinal groove extending from the distal end toward the proximal direction, and the circumference connected to the longitudinal groove and closer to the proximal end than the longitudinal groove by one round in the circumferential direction. With a groove,
In the open state, the lid can be rotated with respect to the neck portion with a virtual axis connecting the support protrusions as a support shaft in a state where the support protrusions are in contact with the longitudinal groove portion. Furthermore, the support protrusion is configured to be able to move in the longitudinal groove,
