Description

  The present invention relates to a bottle for storing and selling a product such as a medicine, particularly a bottle having a substantially cylindrical neck and a transporting projection protruding from the side of the neck, after the product is filled in the bottle. The present invention relates to a protective structure having an opening detection property that can be easily found even if the three parties remove the lid of the container.

  In order to prevent the act of secretly opening the container after the product has been filled and removing the product inside or removing foreign matter from the inside after the product is filled, a protective member is provided to cover the opening of the container. The container cannot be opened unless the protective member is destroyed. As such a protective structure, an automatic heating and packaging device covers the entire container and the periphery of the lid with a heat-shrinkable film so that it cannot be opened unless a part of the film is cut off, or the side wall of the lid It is known that a fragile line that goes around the bottle is provided, and the lower part of the lid is cut off at the time of opening and remains on the neck of the bottle.

The invention described in 1994 Utility Model Publication No. 6-24356 is a protective cap made of synthetic resin provided for detection of opening in a container having a cylindrical neck and a cover fitted on the neck. A cylindrical protective cap body is provided with an upper wall, a retaining projection, and an opening cutout. The protective cap body has an inner diameter larger than the outer diameter of the container lid and the mouth, and is formed deeper than the height of the lid or the position of the ridge of the mouth. An upper wall is formed at the upper end of the main body to prevent the lid from coming out, and a plurality of retaining projections are formed on the inner side of the side wall to engage the container lid or the outer periphery of the container, and above the protective cap. Is prevented from moving. The protective cap body is formed with two vertical grooves formed at a predetermined interval, and the protective cap is removed by cutting a small piece between them using the corresponding slit of the upper wall portion. It breaks so that the container lid can be opened.

  In the above invention, when a protective cap is put on the lid that is screwed into the container at the time of packaging, the protrusion formed obliquely upward on the inner peripheral wall of the protective cap body engages with the bottom of the lid to protect it. The cap is prevented from moving upward, and the protective cap body is maintained in a state of covering the side wall of the container lid. The inner wall of the protective cap is slightly larger in diameter than the container lid, and the surface is finished smoothly, so even if you try to turn the lid by applying force from above the protective cap to open the container, the protective cap Spins over the lid and cannot easily be loosened. When opening, if you pinch between the slits in the upper wall and cause it, the protective cap body will be cut along the two grooves to open the ring so that it can be removed from the container lid. What is necessary is just to open a removal lid body.

In addition, the container described in Japanese Patent Application Laid-Open No. 2005-153964 covers the entire peripheral wall from the upper surface of the cap for opening detection in the mouth structure of the container including a container body having a cylindrical neck portion and a cap fitted on the neck portion. A sealing tube is provided. The sealing tube is provided with a cutting strip that cuts the entire length so that it can be cut off, and an engagement portion that extends inward is provided on the upper surface of the sealing tube to prevent the cap from being pulled out and the sealing tube from being pulled out downward. On the other hand, the elastic engagement piece provided on the inner side of the side surface portion of the sealing tube engages with the annular convex portion of the outer peripheral portion of the container or the lower surface of the peripheral wall of the cap to prevent the sealing tube from coming out upward. In addition, although it is stated that the act of turning the cap together with the envelope can be prevented by providing a gap between the envelope and the cap, on the other hand, a rib is protruded at the lower end to prevent unnecessary rotation of the envelope. It is described that it is installed and brought into contact with the outer periphery of the container (such as 0023).

Moreover, what opened the lower part of the cover body in the case of opening had to be designed individually according to the shape of a container or a cover body, and there was a problem that it was inferior in versatility.

  The protective cap provided with the opening detection property disclosed in Patent Document 1 is made of a synthetic resin that is molded in advance and can be attached after sealing the container. The main body of the protective cap is cylindrical and can rotate with respect to the container mouth. However, the inner surface of the protective cap has a diameter larger than that of the container lid and the surface is smoothed so that the force can be applied from the outside of the protective cap. Even if it turns and rotates, it is comprised so that it may idle with respect to a cover body. However, depending on the material and size of the lid, it cannot be said that it is impossible to open the inner lid by applying a large force from the outside. For products that require strict management, such as chemicals, a more reliable method for detecting the opening of containers is required.

  The sealing cylinder disclosed in Patent Document 2 is also a molded article made of synthetic resin, and a force is applied from above the sealing cylinder by providing a gap between the sealing cylinder and the cap so as to be loosely fitted. Although the act of opening is prevented, as with the above, the detection of opening is not sufficient depending on the material and size of the container, and a more reliable method of detecting opening is required depending on the type of product. .

  An object of the present invention is to provide a bottle cover that can reliably prevent an action of opening the cover from the top of the protective cap, especially in a bottle lid protective structure for a bottle having a transporting protrusion protruding from the side of the neck. It is providing the protection structure of a cover part. Another object of the present invention is to provide a fragile portion that can be easily opened when the protective cap provided around the lid of the bottle having the transporting protrusion is broken and opened along the longitudinal line of weakness. Propose placement.

  According to the first aspect of the present invention, there is provided a bottle having a substantially cylindrical neck portion and a transport protrusion protruding from a side surface of the neck portion, a lid body screwed around the neck portion of the bottle, and a periphery of the lid body. A protective structure of a bottle lid portion comprising a protective cap provided, wherein the protective cap has a substantially cylindrical side surface portion and a circular or annular upper surface portion extending inward from the upper side of the side surface portion. , A hook-like protrusion is provided on the inner side of the side surface portion to lock the lower end of the lid or the annular convex portion on the outer periphery of the bottle neck to prevent the upward movement, and at least at a predetermined interval from the upper surface portion to the side surface portion. Two weak lines are formed in the direction, and the protective cap can be removed by cutting between the weak lines. The side surface and the weak line are below the height of the lower end of the lid. The extension that extends to the neck of the bottle As well as formed by the protective structure of the bottle lid, characterized in that a notch corresponding to the carrying projections on the lower side of the extension portion, to solve the above problems.

  In the protective structure of the bottle lid portion of the present invention, a protective cap made of a synthetic resin that is molded in advance and can be attached from above the lid body after sealing the container is used. The upper surface of the protective cap prevents the cover from coming off to the upper side of the protective cap to prevent it from coming off, and the protective cap itself is moved upward by the hook-shaped protrusion provided inside the side surface. Stop. Furthermore, in order to prevent the lid from rotating with the protective cap attached, in addition to the loosely fitted state between the protective cap and the lid that has been used in the past, the side of the side of the protective cap By providing a substantially cylindrical extension that extends further downward beyond the position of the hook-shaped protrusion, and by providing a notch into which the transport protrusion provided on the side surface of the neck of the bottle enters the extension. Since it is set as the structure which a cap and a bottle cannot mutually rotate, the act which rotates a cover body from on a protective cap can be prevented reliably.
