Description

  The present invention relates to a jig for attaching and detaching a bottle stopper.

  Generally, in the case of a bottle with a stopper, the stopper is often operated by hand when attaching and detaching the stopper and the bottle. It is contaminated or the chemicals contained in the bottle adhere to the hands of workers. Further, with respect to the stopper removed from the bottle, it is difficult to hold the inside of the bottle and the portion in contact with the mouth without contaminating it. This can be a serious problem especially in the stopper of a bottle containing a drug or the like used in a test research institute or a medical institution.

  In addition, Patent Document 1 describes a structure for attaching and detaching the inner lid which facilitates the attachment and detachment of the inner lid of the container and allows the removed inner lid to be held.

Japanese Patent No. 4134105

  An object of the present invention is to provide a means for easily attaching and detaching a bottle stopper.

  In order to solve the above-mentioned problems, the present inventor has found that the above-mentioned problems can be solved by a jig having a structure that effectively transmits the force relating to the attachment / detachment of the plug body, after further earnest research. As a result of repeating, the present invention was completed.

Therefore, the present invention relates to the following jig.
[1] A jig for attaching and detaching a stopper of a bottle, which includes a tubular main body, a screwing portion and an engaging portion provided inside the main body, and the main body is screwed into the bottle. The jig, wherein the plug can be attached and detached by transmitting a force in the direction of the rotation axis generated by the rotation to the plug via an engaging portion.
[2] The jig according to [1], wherein the engaging portion includes a protrusion that engages with the concave portion and / or the convex portion of the plug body.
[3] The jig according to [1] or [2], wherein the engaging portion includes a groove that engages with the convex portion of the plug body.
[4] The cylindrical main body includes a notch parallel to the rotation axis, and the main body can be attached to the bottle via the notch, according to any one of [1] to [3]. Jig.
[5] The jig according to any one of [1] to [4], in which the tubular main body is composed of two or more parts divided by a plane parallel to the rotation axis.
[6] The jig according to [5], further including a hinge that rotatably connects two or more parts.
[7] The jig according to any one of [1] to [6], further including a grip portion provided outside the main body.

  According to the present invention, the plug can be attached and detached by transmitting the force in the rotation axis direction generated by the rotation of the screwed portion to the plug through the engaging portion. By detaching the plug while covering the plug with the tubular main body, the plug can be prevented from being contaminated, and scattering of contents and the like attached to the plug can be avoided.

FIG. 1 is a diagram showing an embodiment of a bottle and a stopper using a jig. FIG. 2 is a view showing an embodiment of a jig according to the present invention.

  Hereinafter, the jig of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. In addition, in each drawing, the size of each member may be emphasized as appropriate for ease of explanation, and the illustrated members do not necessarily show actual sizes and ratios.

  Hereinafter, one aspect of a bottle using the jig of the present invention will be described. As shown in FIG. 1 (A), the bottle 20 has a main body 21, a neck portion 22 provided on the upper portion of the main body 21, and a mouth portion 23 located at the upper end of the neck portion 22, and around the neck portion 22. The screwing portion 24 is provided. The stopper 30 attached to the bottle 20 has a base portion 31 and a top plate portion 32.

  The top plate portion 32 has a diameter larger than that of the base portion 31, and protrudes outward to form a convex portion 33, and the base portion 31 forms a concave portion 34. As shown in FIG. 1B, when the stopper 30 is inserted into the bottle 20, the base portion 31 comes into close contact with the inside of the neck portion 22, and the lower surface of the top plate portion 32 covers the mouth portion 23.

  Hereinafter, one aspect of the jig of the present invention will be described. As shown in FIG. 2 (A), the jig 10 has a threaded portion 14 and an engagement portion 15 provided adjacent to each other inside a tubular main body 11, and the threaded portion 14 is a bottle. The engaging portion 15 is configured to be engageable with the plug body 30 by being screwed into the screwing portion 24 of 20. The engagement portion 15 may include a protrusion (annular protrusion 151) and / or a groove (annular groove 152).

  By attaching the jig 10 to the bottle 20 and rotating it, a force in the rotation axis direction (vertical direction) is transmitted to the plug body 30 through the engaging portion 15, so that the bottle 20 and the plug body 30 are detached from each other. It The jig 10 can be made of a rigid material such as ABS resin or PLA resin.

  The plug body is, for example, fitted (engaged) with the annular groove 152 to the convex portion (top plate portion 32, convex portion 33) of the plug body 30 and / or smaller than the outer diameter of the top plate portion 32. The annular projection 151 having the inner diameter is brought into contact with (engaged with) the recesses (the base 31, the recess 34, and the lower surface of the top plate portion 32) of the plug body 30 to transfer the force in the direction of the rotation axis to the plug body for removal. You can also do it.

  In the present invention, the term "cylindrical" means a hollow cylindrical shape or a shape obtained by cutting a part of a hollow cylinder. The main body of the jig 10 can be attached to the bottle 20 in the horizontal direction by cutting out (notching) a part of the cylinder along a plane parallel to the rotation axis. As shown in FIG. 2 (A), the main body may be composed of a first part 12 and a second part 13 in which a cylinder is divided into two (180 ° cutouts) in a plane parallel to the rotation axis.

  Then, when these are rotatably connected by a hinge 17 and attached so as to sandwich the neck portion 22 and the plug body 30, the plug body 30 is held inside the cylindrical main body 11 and is accidentally dropped or polluted. It is possible to prevent the contents attached to the stopper 30 from scattering.

  The main body 11 can be provided with irregularities as the grip portion 18 along the circumferential direction. An operator can apply force by grasping the main body 11 accurately by putting his / her finger on the grip portion 18. As shown in FIG. 2A, the grip portion 18 on the side opposite to the hinge 17 is largely projected to function as a knob when the jig 10 is opened and closed, so that the plug body 30 can be firmly held.

  When the bottle 20 is a PFA container that contains high-purity reagents, the stopper body 30 is generally dimensioned so as to be press-fitted into the bottle, and therefore the stopper body 30 needs to be detached and attached with force. Therefore, as shown in FIG. 1B, a spacer 25 having a diameter smaller than that of the top plate portion 32 is provided on the mouth portion 23 so that the finger can be easily put on the more protruding portion (the convex portion 33). It is configured. The annular protrusion 151 of the present invention can be inserted into the spacer 25 (recess).

As is clear from the above description, the jig of the present invention can be realized in various modes, but is not limited to the above. The engaging portions (projections, grooves) of the jig may have any shape and combination as long as they engage with the concave portions and the convex portions of the plug body and transmit the force in the rotation axis direction.

  According to the present invention, the force in the direction of the rotation axis generated by screw-rotating the jig is effectively transmitted to the plug body, so that the plug body can be detached and attached, the contamination of the plug body can be prevented, and the work safety can be secured.
