Description

  TECHNICAL FIELD The present invention relates to a resin cap used for sealing a sealed portion of a vial bottle or the like with a stopper and then sealing the sealed portion, and a container with a resin cap using the same. Is.

  2. Description of the Related Art Conventionally, a medicinal bottle or the like having a substantially cylindrical mouth as represented by a vial has been sealed by fitting a flanged stopper to the mouth. In order to enhance the above-mentioned sealing performance and prevent tampering by a third party, the sealing portion is covered with a soft metal thin plate such as aluminum, or a metal cap is attached to a resin cap. For example, a cap is put on (see, for example, Patent Document 1).

  However, those coated with a soft metal thin plate such as aluminum take a long time to open cleanly, and there is a problem that the opening of a stopper or bottle tends to be damaged when a tool for opening is used. Further, a sealing cap having a metal peeling tab may not be safe because it may injure fingers at the end of the peeling tab during the opening operation.

Then, what has produced such a cap for sealing only with resin, and can be opened easily is proposed (for example, refer patent document 2).
Japanese Patent No. 2739455 JP-A-9-238998

  However, the sealing cap of Patent Document 2 includes a portion that fits into the container mouth portion, and a top plate that is connected to the portion via a thin bridge portion, and pulls the top plate to remove the bridge portion. The top plate is removed by cutting, and only the upper surface of the stopper covering the container mouth is exposed. For this reason, although it is suitable for uses such as inserting the injection needle into the exposed top surface of the stopper and extracting the chemical solution in the container, it is prepared separately when removing the stopper from the container mouth and removing the contents. In the case where a nozzle for taking out the contents is used in place of the stopper, there is a problem that the sealing cap cannot be used. In addition, if the portion of the sealing cap that fits into the container mouth portion remains on the container side, and the container is a glass bottle, the remaining portion of the glass bottle body and the resin sealing cap There is also a problem that it takes time to separate and discard them.

  The present invention has been made in view of such circumstances, and effectively seals a sealed portion composed of a container mouth portion and a stopper, and is easy to open. After opening, the entire cap is containerized. An object of the present invention is to provide an excellent resin cap that can be completely removed from the container and a container using the resin cap.

  In order to achieve the above object, the present invention is such that a plug is fitted and sealed in a substantially cylindrical mouth portion during storage, and other members are crowned in place of the plug during use. It is a resin cap used for sealing the sealing portion with a stopper fitted into the mouth of the container, and covers the periphery of the sealing portion from the side. A peripheral wall portion and a top surface portion covering at least a peripheral edge portion of the upper surface of the plug body are integrally formed, and the peripheral wall portion is a belt-like portion having a predetermined width extending in the circumferential direction of the peripheral wall portion. A cutting guide for pulling out the above portion to the outside is provided, and by pulling out the portion of the peripheral wall portion that is a belt-like portion and more than half a circle to the outside, the entire resin cap can be And removed from the sealed part consisting of plug The resin cap that is a so that the first aspect.

  In addition, the present invention includes a resin cap in which a thin portion having a width of 0.2 to 1.0 mm and a thickness of 0.2 to 0.8 mm is linearly provided as the cutting guide. The third gist is a resin cap provided with a notch line having a width of 0.2 to 5.0 mm in which minute connecting portions are formed at predetermined intervals as the cut-out guide.

  The fourth aspect of the present invention is a container with a resin cap that is sealed for tampering using the resin cap according to any one of the first to third aspects.

  That is, the resin cap of the present invention seals a sealed portion composed of the container mouth portion and the plug body by the integrally formed peripheral wall portion and top surface portion, and improves its sealing performance and prevents tampering. Can be done. And when opening and using, a predetermined cut-out guide provided on the peripheral wall portion draws out a portion of the peripheral wall portion that is a belt-shaped portion having a predetermined width extending in the circumferential direction and having a half or more circumference outward. Since it can be completely removed from the sealed portion by cutting it out, the opening operation is simple, and it is easy to dispose as separated waste. And when a container is a glass bottle, when discarding this container, since the resin part does not remain, it has the advantage that it is easy to dispose. Moreover, when the strip-like portion of the peripheral wall portion is pulled out by the opening operation and cut off, the container mouth portion is not damaged, so that other members such as a content extraction nozzle and an opening / closing cap are attached to the container. When used, the crowned portion has a high degree of sealing and can be used satisfactorily.

  Among the resin caps of the present invention, in particular, as the cutting guide, a thin wall portion having a width of 0.2 to 1.0 mm and a thickness of 0.2 to 0.8 mm provided in a line, or the above cutting As a guide, a part provided with a notch line with a width of 0.2 to 5.0 mm in which minute connecting portions are formed at predetermined intervals is cut out by pulling a part of the peripheral wall portion and the top surface portion outward. The operation can be performed smoothly, which is preferable.

  Further, the container with a resin cap of the present invention is safe because the resin cap enhances the sealing performance and prevents tampering. And as already mentioned, not only the opening operation of the resin cap is easy and easy to use, but also the resin cap and the container can be disposed of separately as separated waste, and the disposal is easy. . In addition, when the container mouth is used with another member crowned, the mouth portion is not damaged by the opening operation, so that the crowned portion is highly sealed and can be used satisfactorily.

  Therefore, the container with a resin cap of the present invention is preferably used as a cosmetic container for storing a milky lotion, a beauty essence or the like in addition to a medicinal bottle.

  Next, the best mode for carrying out the present invention will be described. However, the present invention is not limited to this embodiment.

  FIG. 1 is a perspective view showing an example of the best mode of the present invention, and FIG. 2 is a cross-sectional view taken along the line AA ′. In these drawings, reference numeral 1 denotes a glass vial, which includes a barrel portion 2 and a substantially cylindrical mouth portion 3 having a diameter reduced from that of the barrel portion 2. An outward flange 3 a is formed at the upper end of the mouth 3.

  Further, the mouthpiece 3 of the vial 1 is fitted with a cap-like cap 4 having a ceiling, and the inside of the vial 1 is sealed by this fitting. An outward flange portion 4a is also formed at the upper end portion of the stopper body 4, and the lower surface of the flange portion 4a is engaged with the upper surface of the flange portion 3a of the vial 1 so Sealing is improved.

  A resin cap 5 is attached to the sealed portion formed by the mouth 3 and the stopper 4 of the vial 1. The resin cap 5 is made of an integral molded product of polypropylene, and includes a peripheral wall portion 6 that covers the periphery of the sealing portion from the side, and a top surface portion 7 that covers the peripheral edge of the upper surface of the plug body 4 in an annular shape. Yes.

  An annular protrusion 6 a that protrudes inward is provided at the lower end portion of the inner peripheral surface of the peripheral wall portion 6, and this portion is engaged with the flange portion 3 a of the vial 1. Further, an annular projection 7a is provided on the lower surface inside of the top surface portion 7, and the annular projection 7a of the top surface portion 7 is engaged by the engagement of the annular projection 6a and the flange portion 3a of the vial 1. The upper surface of the plug 4 is pressed. Therefore, the sealing of the sealing portion between the mouth 3 and the stopper 4 of the vial 1 is further sealed by the attachment of the resin cap 5.

  Further, the peripheral wall 6 of the resin cap 5 is formed with a narrow notch 8 extending upward from the lower edge to the front of the upper edge, and from one end edge of the notch 8 In the circumferential direction, two upper and lower linear thin portions 9 and 9 ′ that extend around the peripheral wall portion 6 and extend to the other end edge of the notch portion 8 are provided in parallel to each other. However, the lower linear thin-walled portion 9 is formed so that the center of the thin-walled portion is positioned on a line 2 mm above the lower end edge of the peripheral wall portion 6 with respect to the peripheral wall portion 6 having an outer diameter of 26 mm and a height of 13 mm. The upper thin linear portion 9 ′ is formed on the line 4 mm below the upper edge of the peripheral wall 6 so that the center of the thin portion is located, and the distance between them is set to 7 mm. (See FIG. 2).

  Of the strip-shaped portion sandwiched between the two linear thin portions 9, 9 ', a predetermined portion extending from one end edge of the notch portion 8 is warped outward so as to protrude outward. Thus, it is easy to put a finger on the protruding portion 10.

  And since the said linear thin part 9, 9 'is width 0.8mm, thickness 0.4mm, and the intensity | strength of the part is weaker than another part, a finger | toe is applied to the said protrusion part 10, When the strip-shaped portion sandwiched between the two thin linear portions 9 and 9 'is pulled out, this portion is cut in the circumferential direction along the thin linear portions 9 and 9', and the flange portion 3a of the vial 1 is obtained. The annular protrusion 6a of the peripheral wall portion 6 that has been engaged with is also removed together with the belt-like portion. Further, the lower edge portion of the peripheral wall portion 6 below the linear thin wall portion 9, and the upper edge portion and the top surface portion 7 of the peripheral wall portion 6 above the linear thin wall portion 9 'are also cut off and removed at the same time.

  Thus, the vial 1 with the resin cap 5 crowned is, in that state, a sealed portion constituted by the mouth portion 3 and the stopper 4 is sealed by the resin cap 5, Its sealing performance is enhanced and tampering prevention is provided, which is safe.

  And when using the said vial bottle 1, a finger | toe is put on the protrusion part 10 provided in the surrounding wall part 6 of the said resin caps 5, and the two linear thin parts extended from this protrusion part 10 in the circumferential direction The entire resin cap 5 is completely removed from the periphery of the mouth part 3 of the vial 1 by a simple operation of pulling out the band-like part between 9 and 9 'and cutting it out. The fitting part of the plug 4 can be exposed. The resin cap 5 removed from the sealed portion can be easily disposed of as separated garbage.

  In addition, as shown in FIG. 3, the vial bottle 1 of this example is used by removing the stopper 4 and wearing a resin nozzle 20 that can take out the contents little by little. Since the opening operation of the cap 5 is performed by the operation of sequentially pulling out the strip-shaped portion that completely covers the mouth 3 of the vial 1, particularly the outer peripheral surface of the flange portion 3 a, the cutting edge of the strip-shaped portion is There is no possibility of incurring a situation in which it cannot be forcibly opened without coming off from the periphery of the mouth 3. Therefore, the outer peripheral surface of the flange portion 3a is not damaged, and there is an advantage that liquid dripping does not occur between the nozzle 20 and the mouth portion 3. In addition, in the case of using other members such as an open / close-type resin cap instead of the plug body 4, the same advantage can be obtained.

  In the above example, the material of the resin cap 5 is not limited to polypropylene, but various resins can be used. From the viewpoint of flexibility, moldability, etc., an olefin resin such as polypropylene and polyethylene is used. It is preferable to use it.

  Further, in the above example, the linear thin-walled portions 9 and 9 ′ need not be provided on the entire circumference of the peripheral wall portion 6. Then, the resin cap 5 can be pulled out from the mouth portion 3 in the lateral direction. In this case, for example, as shown in FIG. 4, the end portion of the lower linear thin portion 9 of the two linear thin portions 9, 9 ′ hangs down to the lower end of the peripheral wall portion 6. It is preferable to be able to detach.

  Furthermore, the width and thickness of the linear thin-walled portions 9 and 9 ′ provided as a cutting guide for cutting the peripheral wall of the peripheral wall portion 6 into a strip shape are not limited to the above example, and depend on the material of the resin cap 5. , It is set to such an extent that the portion can be easily cut out with a human finger. Usually, the width is preferably set to 0.2 to 1.0 mm, and the thickness is preferably set to 0.2 to 0.8 mm.

  Note that, as the cutting guide, instead of the linear thin-walled portions 9 and 9 ′, as shown in FIG. 5, a notch line 31 in which a minute connecting portion 30 is formed at every predetermined interval may be provided. . The notch line is provided in the same arrangement as the linear thin-walled portions 9 and 9 ', and the band-like portion sandwiched between the two notch lines 31 is pulled out to the outside with a human finger, and the minute connection is made. By cutting off the portion 30, the same effect can be obtained. When such a notch line 31 is provided, the width thereof is usually set to 0.2 to 5.0 mm, although it depends on the material of the resin cap 5 and the size and interval of the connecting portion. is there.

  Further, the width of the band-shaped portion cut out by the two linear thin portions 9, 9 'is not particularly limited, but the above-mentioned band-shaped portion is in a state where the resin cap 5 is attached to the vial bottle 1. The engaging portion between the annular protrusion 6a of the peripheral wall portion 6 and the flange portion 3a of the mouth portion 3 of the vial 1 must be covered. That is, the above-mentioned engagement must be disengaged by cutting out the belt-like portion.

  And it is preferable that the said two linear thin parts 9 and 9 'are not formed in the part facing the outer peripheral surface of the flange part 3a of the opening part 3. FIG. That is, when the strip-shaped portion is cut by the two linear thin-walled portions 9, 9 ', if the cut edge is on the outer peripheral surface of the flange portion 3a, the cut is temporarily failed and scissors are put on the portion. This is because there is a risk of scratching the outer peripheral surface of the flange portion 3a even when the contact is cut off.

  Furthermore, it is not always necessary to form the two thin linear portions 9, 9 'and the notch line 30 provided as a cutting guide for cutting the peripheral wall of the peripheral wall portion 6 into a strip shape, but only the upper one is provided. But it doesn't matter. That is, as shown in FIG. 6, even when only the linear thin portion 9 ′ is provided around the peripheral wall portion 6, an annular protrusion 7a (see FIG. 2) is provided below the top surface portion 7. If it is made, the top surface portion 7 is not easily shaken during the opening operation, so that the belt-like portion can be cut out smoothly. Similarly, when the thickness H of the peripheral wall portion 6 above the linear thin-walled portion 9 'is set to a sufficient size, the belt-like portion can be cut out smoothly.

  The container to which the resin cap 5 is attached is not limited to the vial 1 in the above example, and various containers can be used. However, since it is necessary to attach the resin cap 5, it must have a structure having a substantially cylindrical mouth 3 and sealing the mouth 3 with a plug 4. At the time of use, the plug 4 must be removed from the mouth 3, and other members such as the resin nozzle 20 for taking out the contents must be worn and used.

It is a perspective view which shows one Example of this invention. It is AA 'sectional drawing of FIG. It is explanatory drawing of the usage condition of the said Example. It is a partial explanatory view showing another example of the present invention. It is explanatory drawing which shows the modification of the cutting guide of this invention.
