However, the container described in Patent Document 1 has a structure in which an insertion piece provided in a cap (lid body) is inserted into a nozzle portion (opening) at the mouth of a tube container (container body) to seal the contents. There is a problem that a sheet for maintaining protection and virginity cannot be provided.
The container described in Patent Document 2 is provided with a sealing material (sheet) that covers the tip opening (opening) of the neck (mouth) of the container body, but the sheet is removed by initial opening and then sealed again. When the lid (lid body) is engaged, the lid is mounted at a predetermined position on the container body because of the structure in which the lid is further rotated after the engaging protrusion of the lid (lid body) has overcome the protruding ribs of the container body to ensure the sealing property. There is a problem that the timing of recognizing this and the timing of sealing are different.

An object of the present invention is to provide a sheet that covers the opening of the mouth of the container body, and the lid is attached to a predetermined position of the container body when the sheet is resealed even after the sheet is removed by the initial opening. It is an object of the present invention to provide a container capable of approaching the timing of recognizing that the container has been used and the timing of sealing.

The container of the present invention includes a container body having a mouth portion provided with an opening and a lid body that is detachably attached to the container body and opens and closes the opening, and the lid body has the mouth portion screwed. A tubular portion to be inserted while being fitted and an end face portion for closing the axial end portion of the tubular portion are provided, and one of the mouth portion and the tubular portion is of the mouth portion and the tubular portion. A convex portion protruding toward the other and an annular first contact portion extending in the circumferential direction at a position closer to the end face portion than the convex portion are provided, and the other of the mouth portion and the tubular portion is the said. It is characterized by having a recess for receiving the convex portion and a second contact portion which is provided in an annular shape extending in the circumferential direction at a position closer to the end face portion than the concave portion and abuts on the first contact portion. And.

According to the present invention, when the lid body is mounted on the container body while rotating, the convex portion provided on one of the mouth portion of the container body and the tubular portion of the lid body hits the other of the mouth portion and the tubular portion. The mouth is inserted into the tubular portion while increasing the diameter of the tubular portion. After that, when the convex portion is received by the concave portion provided on the other side of the mouth portion and the tubular portion, the diameter of the tubular portion returns to the original value, and the first contact provided on one of the mouth portion and the tubular portion. The portion abuts on the second contact portion provided on the other side of the mouth portion and the tubular portion to perform sealing. At this time, since the structure is not such that the insertion piece is inserted into the opening of the mouth, a sheet covering the opening of the mouth can be provided. Further, even after the sheet is removed by the initial opening, when the convex portion is received by the concave portion, the first contact portion abuts on the second contact portion to seal the container, so that the lid body is the container body. It is possible to approach the timing at which it is possible to recognize that the lid is mounted at a predetermined position and the timing at which sealing is performed.

In the container of the present invention, the lid preferably includes a pressing portion that is pressed against the mouth portion.

According to the present invention, since the lid presses the pressing portion against the mouth portion, the opening of the mouth portion can also be sealed at the pressing portion, and the sealing property is improved even after the sheet is removed by the initial opening. Can be done.

In the container of the present invention, the tubular portion includes a first tubular portion that can be screwed into the inserted mouth portion and a second tubular portion provided at a position inside the first tubular portion. The convex portion and the first contact portion are provided on one of the mouth portion and the second tubular portion, and the concave portion and the second contact portion are provided on the mouth portion and the second tubular portion. It is preferable that it is provided on the other side of the portion.

According to the present invention, since the second tubular portion is provided inside the first tubular portion that can be screwed into the mouth portion, and the contact portions are provided on the second tubular portion and the mouth portion, they are provided with each other. Each abutting portion in the abutted state can be surrounded by a first tubular portion having a screwed mouth portion, and the sealing property can be improved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
When the direction is indicated in the following description, as shown in FIG. 1, the state in which the container 1 is placed with the lid 3 facing up is used as a reference.

[overall structure]
In FIG. 1, the container 1 stores foods such as seasonings and margarine, and is a molded resin product.
The container 1 includes a container body 2, a lid 3, and a sheet 4.

As shown in FIG. 2, the container main body 2 includes a mouth portion 21 provided with an opening 21A and a body portion 22 continuous with the base end of the mouth portion 21. As the container body 2, for example, a so-called laminated tube can be adopted, and various materials used for this type of container body 2 can be used.

The mouth portion 21 includes an opening 21A, a male screw portion 21B, a reduced diameter portion 21C, a recess 21D, a contact portion 21E as a second contact portion, and a chamfered portion 21F. The mouth portion 21 is made of, for example, a resin molded product such as polyethylene or polypropylene.

The opening 21A is a through hole penetrating the mouth portion 21, communicates with the space inside the body portion 22, and opens to the tip surface 21G of the mouth portion 21.

The reduced diameter portion 21C is provided on the tip end side of the mouth portion 21 with respect to the male screw portion 21B, and is formed in a truncated cone shape in which the diameter gradually decreases toward the tip end portion.

The recess 21D is an annular groove extending over the entire circumference of the outer peripheral surface of the mouth portion 21 and is provided between the reduced diameter portion 21C and the contact portion 21E.

The abutting portion 21E is an outer peripheral surface of the tip portion of the mouth portion 21, and is annularly extending in the circumferential direction at a position closer to the tip portion side of the mouth portion 21 (the end surface portion 34 side of the lid 3 described later) than the recess 21D. It is provided.

The chamfered portion 21F is a portion where the corner portion of the peripheral edge of the tip portion of the mouth portion 21 is chamfered. By providing the chamfered portion 21F, the end portion of the sheet 4 can be easily pinched.

The body portion 22 is formed of a composite film made of, for example, polyethylene, polyethylene terephthalate, aluminum, or the like.

The lid 3 is detachably attached to the container body 2 and opens and closes the opening 21A of the container body 2. As the material of the lid 3, for example, a resin such as polypropylene or polyethylene is used.
As shown in FIG. 3, the lid body 3 includes a side surface portion 31, a first tubular portion 32, a second tubular portion 33, and an end surface portion 34.

The side surface portion 31 has a cylindrical shape provided along the edge of the end surface portion 34, and constitutes the outer peripheral wall of the lid body 3.

The first tubular portion 32 is provided concentrically with the side surface portion 31 at a position inside the side surface portion 31 in a cylindrical shape. The inner surface of the first tubular portion 32 is a female screw portion 32A, and the mouth portion 21 of the container body 2 is inserted while being screwed.

The second tubular portion 33 is provided concentrically with the first tubular portion 32 at a position inside the first tubular portion 32, and is configured to be elastically deformable. The second tubular portion 33 includes a convex portion 33A and a contact portion 33B as a first contact portion.
The convex portion 33A is a portion received by the concave portion 21D of the lid body 3, is provided at the tip portion of the second tubular portion 33, and projects from the inner peripheral surface of the tip portion toward the mouth portion 21. In the case of the present embodiment, the convex portion 33A is formed in an annular shape extending over the entire circumference on the inner peripheral surface of the second tubular portion 33. The protrusion amount D1 of the convex portion 33A is smaller than the depth D2 of the concave portion 21D.
The contact portion 33B contacts the contact portion 21E of the container body 2. The contact portion 33B is an inner peripheral surface of the second tubular portion 33, and is provided in an annular shape extending in the circumferential direction at a position closer to the end surface portion 34 than the convex portion 33A. The inner diameter D3 (see FIG. 3) of the contact portion 33B is the same as or smaller than the outer diameter D4 (see FIG. 2) of the contact portion 21E.

The end face portion 34 has a substantially circular shape in a plan view, and closes the axial end portions of the side surface portion 31, the first tubular portion 32, and the second tubular portion 33. The end face portion 34 includes a pressing portion 34A.
The pressing portion 34A is a portion to be pressed against the mouth portion 21 of the container body 2, and projects in the axial direction of the lid 3 from the inner surface of the end surface portion 34 toward the mouth portion 21 in the area surrounded by the second tubular portion 33. At the same time, it is formed in an annular shape along the tip surface 21G of the mouth portion 21 of the container body 2. When the pressing portion 34A comes into contact with the mouth portion 21, a feeling of resistance is generated. Therefore, the pressing portion 34A has the mouth portion 21 until at least the abutting portion 21E of the container body 2 abuts on the abutting portion 33B of the lid 3. It has a gap D5 between it and the tip surface 21G. The amount of protrusion of the pressing portion 34A is preferably set so that the gap D5 becomes about the thickness of the sheet 4 when the contact portion 21E starts to abut on the contact portion 33B.

The sheet 4 is provided between the mouth portion 21 and the lid body 3 and seals the opening 21A of the mouth portion 21. The sheet 4 is made of, for example, an aluminum foil or a resin sheet such as polypropylene, and is attached to the tip surface 21G of the mouth portion 21 by an adhesive or heat fusion. It is preferable that the sheet 4 is not attached to the chamfered portion 21F of the mouth portion 21, and in this case, the sheet 4 is configured without aluminum so that the end portion of the sheet 4 can be easily lifted from the chamfered portion 21F. Is preferable.

[Installing the lid]
When the lid 3 is attached to the container body 2, the lid 3 is rotated with the tip of the mouth 21 of the container body 2 inserted into the first tubular portion 32 of the lid 3, and the first tubular shape is formed. The mouth portion 21 is screwed into the portion 32. Then, as shown in FIG. 4, the contact portion 21E of the container body 2 hits the convex portion 33A of the lid 3, and the diameter of the second tubular portion 33 is expanded. At this time, the reaction force received from the second tubular portion 33 makes the operation feeling of the lid 3 heavy.

After that, as shown in FIG. 1, when the contact portion 21E of the container body 2 exceeds the convex portion 33A of the lid body 3 and the tip portion of the mouth portion 21 is inserted into the second tubular portion 33, the convex portion 33A is received by the recess 21D of the mouth portion 21, and the diameter of the second tubular portion 33 is restored. As a result, the contact portion 21E of the container body 2 continuously contacts the contact portion 33B of the lid 3 in the circumferential direction over the entire circumference, and the container body 3 is sealed. If the sheet 4 is not removed, the sheet 4 also seals the sheet 4. When the convex portion 33A is received by the concave portion 21D, the reaction force received from the second tubular portion 33 is reduced and the operation feeling of the lid 3 is lightened. Therefore, the lid is changed due to the change in the operation feeling of the lid 3. It is possible to recognize that the body 3 is attached to the predetermined position of the container body 2.

When the sheet 4 is removed in the initial opening, by rotating the lid 3 slightly further, the gap D5 between the tip surface 21G of the mouth portion 21 and the pressing portion 34A disappears, and the lid 3 Since the pressing portion 34A of the above is pressed against the mouth portion 21, the pressing portion 34A also seals.

When removing the lid 3 from the container body 2, the lid 3 is rotated in the direction opposite to that when the lid 3 is attached. As a result, in the lid body 3, the end surface portion 34 moves in the direction away from the tip end surface 21G of the mouth portion 21, and the convex portion 33A comes off from the concave portion 21D, so that the lid body 3 can be removed from the container body 2.

[Effect of Embodiment]
According to the present embodiment, when the lid 3 is attached to the container body 2 while rotating, the convex portion 33A provided on the second tubular portion 33 of the lid 3 hits the mouth portion 21 and the second tubular portion The tip of the mouth portion 21 is inserted into the second tubular portion 33 while expanding the diameter of the 33. After that, when the convex portion 33A is received by the concave portion 21D provided in the mouth portion 21, the diameter of the second tubular portion 33 is restored, and the contact portion 33B provided in the second tubular portion 33 is changed. Sealing is performed by contacting the contact portion 21E provided on the mouth portion 21. At this time, since the insertion piece is not inserted into the opening 21A of the mouth portion 21, the sheet 4 covering the opening 21A of the mouth portion 21 can be provided. Further, even after the sheet 4 is removed in the initial opening, when the convex portion 33A is received by the concave portion 21D, the abutting portion 33B abuts on the abutting portion 21E to seal the lid body 3. The timing at which it can be recognized that the container body 2 is mounted at a predetermined position and the timing at which sealing is performed can be brought close to each other.

Further, since the lid 3 presses the pressing portion 34A against the mouth portion 21, the opening 21A of the mouth portion 21 can also be sealed by the pressing portion 34A, and the opening 21A of the mouth portion 21 is not sealed by the sheet 4. Even in this case, the sealing property can be improved.

Further, since the protrusion amount D1 of the convex portion 33A is smaller than the depth D2 of the concave portion 21D, the contact portion 21E and the contact portion 33B can be reliably brought into contact with each other, and the sheet 4 has the convex portion 33A and the concave portion. It is possible to prevent the sheet 4 from being damaged when it is sandwiched between the 21D and the sheet 4.
