[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cylindrical container or a tube-shaped container in which a cylindrical container with a lid is hermetically packaged with a packaging film material so that it can be easily opened. The present invention relates to a cylindrical container packaged with a provided label or cover film.
[0002]
[Prior art]
A spout is provided at the upper end of the cylindrical container body, and a lid can be detachably provided on the spout to form a cylindrical container, or the barrel can be pressed into a flat shape and squeezed out A container having a tube-like container by detachably providing a lid on a spout formed at the upper end of a container body made of a flexible tubular body, After filling the contents with the lid, the spout is sealed with a lid, and then a label printed with a product name, component display, precautions, etc. on the film material or the like is attached to the outer peripheral surface of the container body. Alternatively, the product is shipped as a product after printing a product name, precautions, etc. on a container body and fixing it with an adhesive or the like.
[0003]
However, labels and other packaging materials made of film material, etc., printed as described above, covered only on the container body, are in a state in which the lid can be easily opened. There is a risk that the contents of the container contained in the container may be used when the lid is opened without permission, but it is difficult to determine whether or not it has actually been opened from the appearance alone.
Therefore, after improving this defect and making it possible to easily determine whether tampering has been made, after filling the contents in the cylindrical container body and then attaching the lid in a sealed state, Cover the entire wall surface of the lid and container body with a label, cover film, etc., and fix them with an adhesive so that they do not fall off, or fix them with a heat-shrinkable cylindrical film, etc. There is.
[0004]
And when the container body and the cover body are integrally covered with such a cover film or the like and the film is fixed to the container body, when the container is opened and used, the film is broken and the cover body is broken. The lid must be opened after exposure.
However, if the label or cover film is transparent, the boundary part between the lid and the container body can be confirmed from the outside, but if it is opaque by coloring or printing, the boundary part is removed. Since it cannot confirm from the outside, when opening a container, it is difficult to cut | disconnect a cover film etc. in a suitable fracture | rupture part.
[0005]
Therefore, in such a container with a tamper-evident piece that is integrally packaged by covering the container body and the lid with a cover film or the like, so-called virgin proof container, the boundary between the container body and the lid can be distinguished. It has been considered that a cutting means is provided so that the broken portion is formed and the portion can be easily broken.
For example, by forming a dotted line perforation on the film surface of the boundary portion between the container main body and the lid body of the cylindrical container covered with a virgin film or the like, a cut display portion colored on the portion is provided, Alternatively, a band-like fractured portion that is continuous in the circumferential direction is formed at the boundary between the container body such as a virgin film or label and the lid, and a colored band or string for cutting is attached to the portion. It is easy to cut.
[0006]
Therefore, the applicant of the present application described below as a container provided with a cutting means for accurately and easily breaking a virgin film or label in which the container is packaged and fixed at the boundary between the container body and the lid. The invention shown in the drawing and other specific examples are proposed in Japanese Patent Application No. 8-36907 as a prior invention.
That is, as shown in FIG. 4, in the cylindrical container 11 having a spout at the upper end of the container body 12 and provided with a lid 13 detachably, the lid peripheral surface in a closed state A perforation that can be cut by a load from the outside on a film portion that covers the peripheral surface of the container body with a virgin film 15 and is bonded and fixed to at least the container body 12 and covers the connection portion between the container body 12 and the lid body 13. Alternatively, an illegal breaker that is provided with an annular break portion 15b made of a U-shaped slit or the like and can be cut by twisting the lid 13 in the opening direction while the container body is fixed with one hand. A cover film-equipped container 11 provided with an opening prevention piece 15a is configured.
[0007]
Alternatively, as shown in FIG. 5, there is provided a rupture portion that is a continuous belt in the circumferential direction along the connecting portion 16 between the container body 12 and the lid 13 such as a virgin film or label 15 that covers and wraps the container. Then, slits 15e and 15f are formed continuously in the circumferential direction at the upper and lower edge portions of the strip-like fracture portion, and a cutting grip portion 15g is extended laterally at one end portion of the fracture portion. The container with a cover film provided with the tamper-evident preventive pieces 15a is formed by cutting the both edges of the rupture portion by pulling the grip portion 15g along the circumferential direction. is there.
[0008]
However, in the above-described prior invention, when there is a gap or a step between the container surface and the label or film at the connecting portion 16 between the container main body 12 and the lid 13, the label or film covering the container The wrinkles 15j are likely to be generated near the gap portion, and the appearance of the product is deteriorated, so that it is handled as a defective product.
In addition, unless the label or film is opaque, the connecting portion 16 between the container body 12 and the lid 13 is difficult to confirm, and the perforation is difficult to see even if a break line such as the perforation 15b is provided. There is a case.
[0009]
[Problems to be solved by the invention]
Even if there is a level difference between the container body and the lid of a container covered with a label or virgin film, the label or film surface will not wrinkle, and the label or film will be transparent and opaque. Regardless of this, it is easy to see between the container body and the lid, and it is easy to see the perforation and other broken parts, so that the broken parts can be easily cut to easily unopened or opened. Be able to judge.
[0010]
[Means for Solving the Problems]
A cylindrical container composed of a cylindrical container body having a spout at the upper end and a lid provided detachably on the spout, and the cover body peripheral surface and the container body peripheral surface are labeled and virgin in a closed state. Cover and fix in a cylindrical shape with a film, etc. and form an annular rupture at the connection between the lid and the container body to form a tamper-proof container, such as a label or virgin film Then, hot air is blown on the surface to shrink and dent, thereby eliminating a step between the lid and the container main body, and providing a broken portion at a position where the connection between the lid and the container main body can be seen.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
A cylindrical container 1A, 1B comprising a cylindrical container or tube main body 2A, 2B and a lid 3 detachably provided at the outlet of the container is provided with a peripheral surface of the lid and the container main body. Covering in a cylindrical shape with a label 5 or the like provided with a cutting means, and fixing them together.
Next, hot air having an appropriate temperature is blown on the surface of the label 5 of the cylindrical container, and the portion of the label covering the connecting portion between the lid portion and the main body portion is recessed in the gap between the lid portion 3 and the main body portion 2A. In such a way that there is no step at the boundary between the lid part and the main body part by contracting, and there is a break part 5b such as a perforation provided on the label surface in the recess of the boundary part 6 between the lid part and the main body part Thus, a cylindrical or tube-shaped container with a tamper-evident piece is formed.
In the container configured as described above, the label is easily cut at the perforation 5b by holding the container body 2A, 2B with one hand and twisting the lid 3 from above the label 5 with the other hand. It is rotated and opened together with the lid 3.
[0012]
【Example】
The characteristics of the container of the present invention will be described below with reference to the drawings based on the optimum embodiment.
As shown in FIGS. 1 and 2, the present invention is a tamper-evident piece on the peripheral surface of a container comprising a lid 3 screwed into a mouth-and-neck part 4 formed at the upper end of a tube-shaped container body 2A. The label 5 provided with 5a is bent into a cylindrical shape by an adhesive 5c and pasted on the peripheral surface of the container main body and the lid, and then contracted by blowing hot air on the label surface to heat the container main body. The label surface of the gap portion 6 where 2A and the lid 3 are joined is recessed in a concave shape, and the label 5 is fixed so as to be in close contact with the entire circumferential surface of the container.
[0013]
In this way, when the label 5 is fixed in close contact with the container, the breaking perforation 5b provided in advance near the upper end of the label is at the boundary portion 6 where the container body 2 and the lid 3 are connected. The tubular container 1 with the tamper-evident piece is configured so as to be positioned and formed on the bottom surface of the concave portion.
The label 5 used in this embodiment is such that an unauthorized opening prevention piece 5a located at the upper end of the perforation 5b provided as a cutting means is adhered to the entire peripheral surface of the lid 3. When it is not necessary to provide the unsealing prevention piece 5a on the entire peripheral surface of the lid 3, the label can be configured as follows.
[0014]
As shown in FIG. 3, the tamper-evident piece 5a provided on the label or the packaging film is sufficiently prevented from being tampered with if the width of about one fifth of the entire circumference of the lid 3 of the container is adhered. Therefore, the label 5 on which printing or the like has been performed has a corresponding width of the tamper-evident prevention piece 5a at an appropriate position of the upper edge, for example, the side edge or the middle portion. In addition, the upper end of the label 5 is cut off from the shoulder of the container body 2, and the label 5 is pasted on the entire peripheral surface of the cylindrical container body 2, and the lid 3 and the connection portion. After the tamper-evident prevention piece 5a is attached to a part of the label 6, the tamper-proof opening piece 5a is contracted by blowing hot air on the surface of the label and heated, and the tamper-evident prevention piece 5a is closely attached to the connecting portion 6 without a gap. It is configured in a cylindrical container with a prevention piece.
[0015]
In the cylindrical container with the tamper-evident preventive piece of the present invention configured as described above, the break portion where the perforation 5b for separating the tamper-evident preventive piece 5a from the label 5 is formed is a connection between the container main body and the lid portion. Since it is on the part 6, in order to open and use this container, it is illegal to hold the container body part with one hand and hold the lid part 3 from above the label 5 with the other hand and twist it. The unsealing prevention piece 5a is always cut at the perforation 5b and rotated together with the lid 3 to be opened, so that the contents of the container can be poured out.
[0016]
Further, in the above embodiment, as shown in FIGS. 2 to 3, as a label or a cover film, a break line made of perforation 5b is provided near the upper end of a substantially rectangular base material to prevent unauthorized opening prevention piece 5a. However, the invention of the present application is not limited to such a label or cover film. As shown in FIG. Slits 15e and 15f are formed at the edge to provide a band-shaped fracture portion to form the tamper-evident prevention piece 5a, and a label or cover film provided with a gripping portion 15g extending laterally at the band-shaped end is used. It is also possible.
[0017]
That is, the label or the cover film as described above is applied to the peripheral surface of the container body and the lid so that the strip-like broken portion exists on the connection portion 6 between the body and the lid of the cylindrical container, and then the label Or it can be set as the cylindrical container with the tamper-evident prevention piece which heated the cover film and was made to contact | adhere to the said connection part concavely.
And in order to open a container to which such a tamper-evident label is affixed, the label is cut by picking up the gripping piece for breaking with a fingertip and pulling it up, and then opening the container by rotating the lid of the container Can do.
[0018]
【The invention's effect】
The invention of the present application eliminates the gap between the label and the container by heating and shrinking a cylindrical container body and a cylindrical body bonded and fixed to the peripheral surface of the lid with hot air. In addition, the label is indented into close contact with the connecting portion between the container body and the lid.
And it is possible to prevent the label from inadvertently dropping off from the container body, or it can be provided so that the broken portion of the tamper-evident prevention piece provided on the label is located in the concave portion. When opening, it can cut | disconnect reliably and easily at a fracture | rupture part.
Therefore, since it is clearly known whether or not the broken portion of the label has been cut, it can be easily determined whether the container is unopened or has been opened.
