Description

  The present invention relates to a blow bottle suitable as a refill container for shampoos, rinses, fragrances, sterilization deodorants, etc., and improves the ease of refilling while realizing recap of the bottle and remaining in the bottle It is intended to avoid quality degradation of the contents.

  Conventionally, as a container for refilling contents such as shampoo and rinse, a bag-shaped pouch formed by laminating thin sheets and blow molding formed from the viewpoint of effective use of resources and reduction of waste Although bottles are applied, this type of container has low nozzle part rigidity, and all of them are virgin types that cannot be sealed once the container is opened. When an object remains, it must be left in the container as it is, and there is a concern that the quality may be affected (for example, see Patent Document 1).

JP 2002-193232 A

  An object of the present invention is to propose a thin-walled blow bottle that can be easily refilled and can be easily recapped without using a cap provided separately.

The present invention has an internal space surrounded by a wall forming a neck, a shoulder, a trunk, and a bottom, the container body having the internal space as a filling space for contents, and rising from the top surface of the neck A blow bottle integrally provided with a dispensing nozzle that forms a dispensing opening connected to the internal space by tearing off the sealing plug,
The neck portion hangs down from the top of the neck portion toward the internal space, and a part of the rising portion is a hinge, and the pouring nozzle of the pouring nozzle is sealed by tilting the pouring nozzle starting from the hinge. A hanging wall,
The drooping wall has a C-shaped planar shape extending from one side end of the pouring nozzle to the other side end, and inside the annular peripheral wall of the neck portion via a hollow portion with respect to the annular peripheral wall. They are spaced away,
Between the lower end edge of this drooping wall and the rising part of the pouring nozzle excluding the hinge, the pouring nozzle is tilted down, and the pulling posture of the pouring nozzle is alternately reversed in the reverse direction. The blow bottle is characterized in that it is provided with an elastic wall portion for raising and maintaining the posture.

Further, the hanging wall, pouring fitted into the infusion out pouring opening of the nozzle in defeat Write-posture of the nozzle may have been provided with a projection to hold the infusion out opening in liquid-tight manner .

  It is desirable that a bottom of the container body is provided with a filling port that can project outward and sink inward, can form a filling port for contents, and can be sealed by heat fusion.

  Since the dispensing nozzle is formed in an elongated shape, it is easy to refill when refilling a container having a small diameter. Further, after opening the container, it is possible to seal the container by simply depressing the pouring nozzle, and the quality of the contents can be maintained.

It is the figure which showed embodiment of the blow bottle according to this invention about the side surface. It is the figure which showed the plane of the bottle shown in FIG. 1 about the neck. It is an external appearance perspective view of the neck of the bottle shown in FIG. It is the figure which showed the state which recapped the opened bottle. It is a principal part enlarged view of an extraction nozzle and a drooping wall.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 to 3 are diagrams schematically showing an embodiment of a blow bottle according to the present invention. FIG. 1 is a view showing a side of the bottle, and FIG. 2 is a plan view of the bottle shown in FIG. FIG. 3 is a view showing the neck (shown with the sealing plug removed), and FIG. 3 is an external perspective view showing the neck of the bottle shown in FIG.

  In the figure, 1 is a container body. The container body 1 has an internal space M surrounded by a wall portion forming a neck portion 1a, a shoulder portion 1b, a trunk portion 1c, and a bottom portion 1d, and the internal space M is used as a filling space for contents. It is molded integrally by blow molding.

Reference numeral 2 denotes an elongated dispensing nozzle. The pouring nozzle 2 is formed so as to rise from a top wall portion 1a ₂ provided integrally with the upper end of the annular peripheral wall 1a ₁ of the neck portion 1a. Reference numeral 3 denotes a sealing plug provided integrally at the tip of the dispensing nozzle 2. This sealing plug 3 can be torn off from a planned fracture portion (thinned weakened portion) L formed at a boundary portion with the dispensing nozzle 2, and is torn by gripping the gripping portion 3 a of the sealing plug 3. As a result, as shown in FIGS. 2 and 3, a pouring hole h connected to the internal space M is formed.

4, dispensing hinge provided on a portion of the rising portion of the nozzle 2 (the rear end portion 2a), 5 is a wall portion provided on the top panel wall portion 1a ₂ of the neck 1a. The wall portion 5 is a suspended wall that hangs down from the edge of the top surface wall portion 1a ₂ toward the internal space M (the top wall portion 1a ₂ is integrally connected to the wall portion 5). It is composed of. The hanging wall 5, is shown as one example the other side edge P ₂ to C shape in plan view extending from the side end P ₁ of the pouring nozzle 2, the recess 5a on the inner side is formed Yes.

  6 is a thin-walled elastic wall provided in the recess 5a. This elastic wall portion 6 connects the lower end edge of the drooping wall 5 and the rising portion of the pouring nozzle 2 excluding the hinge 4 so that the pouring nozzle 2 is raised (in a standing posture). Then, it is reversed so that it becomes convex toward the outside, and the pouring nozzle 2 maintains its standing posture with the elastic force (repulsive force) by this reversal.

  Reference numeral 7 denotes a filling port provided at the center of the bottom 1d of the container body 1. The filling port 7 can protrude outward and can be recessed toward the inside (inside the internal space M). After the contents are filled and recessed (inverted) inside, heat fusion is performed. The bottle is sealed by this heat fusion and distributed as a product. In particular, it is possible to hold the bottle in an upright position by making the filling port 7 into a bottom inverted shape that can be pushed into the internal space M, which is advantageous for displaying products.

  In order to open the bottle in the blow bottle according to the present invention, the grasping portion 3a of the sealing plug 3 may be grasped and the sealing plug 3 may be torn off along the planned fracture portion L. In order to recap the bottle after opening, as shown in FIG. If it does so, the front-end | tip part of the extraction nozzle 2 will contact | abut the drooping wall 5, and the extraction opening h is sealed by it.

  In a state where the dispensing nozzle 2 is tilted down, the elastic wall portion 6 is inverted so as to be convex toward the internal space M, and the pouring posture of the dispensing nozzle 2 is caused by the elastic force accompanying the reversal of the elastic wall portion 6. Will be maintained.

  FIG. 5 is an enlarged view of the distal end portion of the dispensing nozzle 2 in the collapsed state and the main portion of the hanging wall 5 with which the distal end portion abuts. The hanging wall 5 can be provided with a protrusion 8 in advance, and when the pouring nozzle 2 is tilted, the protrusion 8 is adapted to the pouring hole h of the pouring nozzle 2 to improve the sealing performance. It can be further increased.

  The blow bottle according to the present invention is made of a synthetic resin. To produce the blow bottle, a cylindrical body made of synthetic resin is formed by extrusion molding, and then the tip of the cylindrical body Are integrally formed with the neck 1a, the pouring nozzle 2, the sealing plug 3, the hinge 4, the hanging wall 5 and the elastic wall 6, and further, blow molding (biaxial) Stretch blow molding) may be performed, and the production conditions of the blow bottle are not particularly limited.

  The hinge 4 can be formed integrally with the neck portion 1a and the dispensing nozzle 2 by molding by sandwiching the mold, but after forming the bottle, a cutting blade or the like is provided at the boundary between the dispensing nozzle 2 and the neck portion 1a. An incision can also be formed.

  It is possible to provide a blow bottle that can be recapped and easily refilled.
