The application container includes a container main body A provided with an application section 6, and a cap body B that is detachable from the container main body A so as to cover the application section 6.

The coating container will be described in detail below.

<<Container body A>>
The container body A includes a bottle C, which is a storage container that has a bottom wall 11 as a bottom and can accommodate glue inside, and a discharge port PT that is configured to be detachable from the bottle C and that can discharge the glue to the outside at its tip. It is equipped with a nozzle body D which is a discharge body provided with an applicator 6 comprising the following.

The container body A is of a refill exchange type in which after the bottle C is removed from the nozzle body D, another bottle C as a refill can be attached to the nozzle body D.

<Bottle C>
The bottle C has a bottle opening ca formed at its tip, and a storage space sp in which a liquid paste is accommodated. A nozzle body D and a cap body B can each be screwed onto the bottle C.

The bottle C is integrally formed of synthetic resin. The bottle C is made of synthetic resin, which is a flexible and elastically deformable material.

The bottle C includes a bottle main body 1 which is a main part in which glue is stored, a cap body connecting part 2 disposed on the bottle body body 1, and a nozzle disposed on the cap body connecting part 2. The nozzle body connecting portion 3 is provided with a bottle opening ca disposed above the nozzle body connecting portion 3. The bottle C is provided with a first channel R1 through which the glue flows.

[Bottle body part 1]
The bottle main body 1 includes a bottom wall 11 that is substantially circular when viewed from the bottom, and a peripheral wall 12 that is a cylindrical main body that stands integrally from the peripheral edge of the bottom wall 11.

The outer peripheral edge of the bottom wall 11 is provided with a downwardly bulging portion 11b. The bulging portion 11b forms a portion that comes into contact with a placement surface (not shown) such as a top plate when the container main body A is placed vertically on the placement surface.

The peripheral wall 12 can be bent and deformed in response to a pressing and deforming operation by a user or the like. The peripheral wall 12 constitutes a main part that can be flexibly deformed to discharge the glue stored in the storage space sp to the outside. The peripheral wall 12 of the bottle C is elastically deformed in the direction of narrowing the housing space sp in response to a pressing force from the outer surface side, thereby being able to discharge the glue stored in the housing space sp to the outside through the discharge port pt. be.

The peripheral wall 12 has a cylindrical shape. As shown in FIG. 20, the peripheral wall 12 has a generally rectangular cylindrical shape with a cylindrical lower part and four rounded corners 12k at the upper part.

The peripheral wall 12 is formed so that its cross-sectional shape changes while gradually decreasing in diameter from the bottom wall 11 side toward the tip side (bottle opening ca side). In other words, the outer surface of the peripheral wall 12 is formed so as to gradually approach the axis upward. At least the upper portion of the peripheral wall 12 has a rectangular shape with the curved portion 12w serving as a corner portion 12k in a cross-sectional view.

The upper part of the circumferential wall 12, which has a rectangular cylindrical shape, forms the main part that is held by the user's handle, that is, the fingertips of the user's hand during the operation of applying glue. Since the upper part of the peripheral wall 12 has a substantially rectangular cylindrical shape including a flat portion 12h, the user's fingertips do not easily slip when in contact with the peripheral wall 12 during operations such as applying glue.

The peripheral wall 12 includes a plurality of flat portions 12h, that is, four flat portions 12h, and a curved portion 12w that is arranged between adjacent flat portions 12h and curved to form an outward convexity. The flat portion 12h and the curved portion 12w are provided at the upper part of the peripheral wall 12. The peripheral wall 12 is provided with a corner portion 12k by arranging a curved portion 12w that is curved outwardly between adjacent flat portions 12h.

The flat portion 12h has a relatively flat shape. The flat portion 12h is provided at least at the top of the peripheral wall 12. Note that the "flat portion 12h" is not limited to a completely flat area. For example, even if the area is not completely flat, such as a slightly curved area as a whole or a locally uneven area, when compared with the curved part 12w forming the corner 12k, , an area portion whose curvature as a whole is set to be small is included in the concept of "flat portion 12h".

The direction in which the outer surface of each of the four flat parts 12h faces in a plan view is approximately the direction in which the front wall p1, the left and right side walls p2, p3, and the rear wall p4, which constitute the peripheral wall part 61 in the nozzle body D, face in a plan view. It is a match. In other words, the approximately rectangular shape of the upper portion of the peripheral wall 12 is synchronized with the approximately rectangular shape of the applicator 6 provided in the nozzle body D. Note that a nozzle body positioning portion F is provided between the nozzle body D and the bottle C.

The curved portion 12w is set to a degree of curvature that allows it to deform inward when pressed from the outside. In other words, the curved portion 12w is not set to such a large curvature that it hardly deforms inward when pressed from the outside. The curved portion 12w is formed such that the degree of curvature (curvature) gradually increases from the bottom wall 11 side toward the bottle opening ca side.

The direction of rotation is set so that it is attached to the Similarly to the first male threaded part N1, when the nozzle body D is rotated to the left in a plan view, the second male threaded part N2 is configured to screw the nozzle body D into the bottle C and retract. The direction of rotation is set so as to separate it from the bottle C.

The reason why the rotational directions of the first male threaded portion N1 and the second male threaded portion N2 are set in the same direction is that the application container of this embodiment is attached to the nozzle body D when another bottle C is a refill. This is because it is a refillable type product.

That is, the threaded structure that allows the nozzle body D to be detached from the bottle C is adapted to a well-known threaded structure that allows the nozzle body D to be rotated to the left in a plan view. Thereby, the "rotation operation for separating the nozzle body D from the bottle C" to be performed by the user can be smoothly performed without making a mistake.
