Description

[0001] The present invention relates to a tamper-evident cap and a cap combination,

The present invention relates generally to the field of packaging technology, and more particularly to a tamper-evident cap, container, and cap cap and container combination that includes a top panel and a cylindrical skirt suspended from the periphery of the top panel.

The tamper evident closure cap for bottles and other resealable containers is provided with various types of opening-and-confirming features designed to clearly show to the consumer that the container has been opened. Many conventional open-close caps use what is known as a tamper evident band. Normally, the open-check band with the upper edge is a line of weakness, for example by means of a frangible bridge or a scored line, Frangibly connected to the open end of the housing. The opening-confirming band is arranged under a retaining structure, such as an annular retaining ledge, on the container finish, and the retaining structure is threaded on the container finish, section.

A retaining element, for example a radially inwardly directed band, a folded flap or elements protruding from the interior of the opening-check band, is unscrewed for removal, The retaining element with the retaining structure is bonded onto the container to prevent removal of the open-check band. This means that there is a certain degree of resistance to opening the plug until the vulnerable wire or bridge is ruptured so that the plug can be easily removed and the opening-confirming band indicates that the plug has been opened and the opening- Quot ;, respectively.

When the retaining element is formed by an inwardly directed flanged or folded flap, the design of such element is such that the flap or band does not flip open when the axial force is applied to the open- It is preferred that the tamper indicating band is designed to pass back over the retention bead. In addition, the flap or band should be flexible enough to pass over the retention structure when the cap is initially applied to the container.

This is achieved, for example, by using an extension of the flap as shown in US 4546892, where the extension of the flap has a height of the retaining structure of the container when the stopper is in its fully tightened position ). This extension can be clamped between the inner wall of the unseal-indicator band and the retaining structure when the stopper cap is clamped in the container, and can prevent the flap from being inverted.

As an alternative to or in addition to the retaining structure which is effective when an axial force is applied, it is also possible to use a semi-rigid structure, for example, as described in EP 2114786, There is a known unsealing-confirmation band that includes anti-rotational means.

In each case, there is some resistance in which the cap cap is opened until the line of weakness ruptures.

Typically, the fragile line ruptures in the case of a typical attempt to open the container. However, the unsealing-indicator band can be used to prevent rupture of the rupturable connection, if it is attempted abnormally, for example, when a person tries to lift the unsealing band from the receiving element of the container neck, Should be used to indicate this.

It must be difficult for the contents of the container to be unmodifiable or otherwise unopened without being immediately apparent to the user.

The retaining element should be sufficiently rigid to withstand the opening force to rupture the line of weakness, but be flexible enough to capping without stiffing much of the force.

The torque required to open the stopper should not be too high for the elderly to feel comfortable when opening the stopper.

The purpose of the present invention is to provide a method of making a toe closure that can be easily handled during opening and capping while the line of weakness is ruptured before the closure is substantially opened It has a stopper.

According to the present invention there is provided an apparatus comprising an upper panel, a cylindrical skirt depending from a periphery of the upper panel, and a frangibly connected open- a tamper indicating band is provided.

The unsealing-display band includes an annular retaining band that is hingedly connected at a lower edge. The retaining band is directed toward the upper panel and extends radially inward when the cap is in a screwed on position.

Due to the shape of the retaining band, the retaining band may be arranged in the downward direction and may be molded, and the retaining band or stopper may be reheated or reentered without further re- The band can be folded later to be stably arranged in the upward direction.

Wherein the annular retaining band comprises a plurality of circumferential sections having the same circumferential length, the circumferential sections being spaced apart from each other by a distance greater than or equal to at least a distance from each other to form a flap, Separated.

Each flap has a maximum axial length selected to extend at least axially above the engagement surface of the retaining structure arranged on the container neck when the cap is in the clamped position (maximal axial length). Thus, the free edges of the flaps and the distal flap regions in the distal position relative to the lower edge of the unsealing-indicator band are inserted between the retaining structure and the skirt when the cap is provided in the container. Interposed. Thus, the annular band is prevented from bending downwardly as shown in US 4546892.

The outer circumferential portions of the annular retaining band each have two or more projections with a plug engagement surface. The protrusions extend radially toward the interior of the cap to engage below the mating surface of the retaining structure arranged on the neck of the container when the cap is in the tightened position.

The maximum axial length of the flap is longer than the axial length of the projection. In the clamped position, the free edges of the circumferential portions are above the axial level of the plug engagement surface and thus above the engagement surface of the retaining structure.

The closure cap according to the present invention provides two elements for fixing the cap cap in combination when it is improperly opened. The first element is the maximum axial length of the flap. When the cap cap is provided in the container, the free edges of the flap are positioned between the inner wall of the cap cap and the retaining structure of the container and prevent the inwardly bent retaining elements from flipping down. The second element is the stability of the protrusion which causes the axial force to be applied to the top line when the cap is opened.

The outer circumferential portions of the annular retaining band each additionally have a hole between the protrusions on the outer circumferential portion.

These holes are provided to discharge residual liquid that may remain between the interior of the cylindrical skirt and the neck of the container. For optimal ventilation, the holes are arranged close to the lower edge of the opening-confirming band and are configured to communicate with the space between the cylindrical skirt and the neck of the container. In addition, these holes reduce the overall stiffness of the retaining band and allow it to flex readily inward during capping.

The holes may be openings in an annular band that may have any form of cross-section. The holes preferably have a rectangular cross-section.

The sum of the lengths in the circumferential direction of the holes and the protrusions on one circumferential direction portion is shorter than the circumferential length of the circumferential portion, that is, there is a circumferential area of the circumferential portions without holes or protrusions It means.

It is preferable that there is no hole between adjacent projections on different circumferential direction portions.

In one preferred embodiment of the present invention, the holes are located near the adjacent protrusions and in direct contact with the protrusions.

Between the adjacent projections on the outer circumferential portion, connection elements are preferably located which connect with the plug engagement surface of the projections. The connecting elements have an engaging surface that is aligned in parallel with the engaging surface of the adjacent protrusion.

During opening, the axial forces are distributed in the total circumferential length of the engagement surface and are thus distributed not only on the coupling elements but also on the mating surfaces of the projections, and stiffness is mainly caused by the projections. Thus, while the retaining band is flexible enough to be easily provided on the neck of the container, the retaining band nevertheless allows a steady rupture of the vulnerable line during opening.

In a preferred embodiment of the present invention, the distance between adjacent projections on the outer circumferential portion is the same as the distance between adjacent projections on the different circumferential portion.

It is preferable that all protrusions have the same circumferential length.

Thus, the protrusions are uniformly distributed around the circumference of the cap cap.

According to one exemplary embodiment, the flaps are formed by adjacent portions separated by a V-shaped gap. Thus, the circumferential portions generally have a trapezoidal shape. It is preferred that the axial length of the V-shaped gap is shorter than the axial length of the retaining band, and more preferably, there is no hole between the lower edge of the opening-check band and the gap, There is a closed surface of an annular band which is located in the region where the adjacent outer circumferential portions meet.

In particular, the annular band basically has the same radial thickness all around the band periphery. The total thickness varies only with holes, gaps, protrusions and connecting elements. According to the present invention, bending downward the entire flange will be much more difficult than bending the annular band including the flaps separated by the V-shaped gap downward.

Preferably, the protrusion has a wedge shape in which the thickness in the radial direction is increased each time the distance of the lower edge of the opening-confirming band is increased. In particular, the projections have the form of a compact wedge to provide a stable structure to withstand axial forces. Alternatively, the protrusions may have a pocket that is opened toward the upper panel when the cap cap is screwed on. The pocket may have a groove or an undercut shape.

A radial force is applied to the annular band when a cap cap is provided in the container and the protrusion must pass over the thread and / or retaining structure. Due to the annular band divided into the partially separated outer circumferential portions, these portions are deflected radially outwardly. The protrusions pass back through the retaining structure and return to their original positions when engaged under the retaining structure.

In one preferred embodiment of the present invention, the outer circumferential portions each have at least one circumferential rib, the outer circumferential ribs radially outer toward the unsealable band cap when the cap is in the tightened position, Lt; / RTI >

Due to the ribs, there is a certain distance between the inner wall of the opening-confirming band and the annular band, so that when the cap is in the clamped position, the protrusion is radially inwardly engaged with the retaining structure of the neck- Lt; / RTI >

In addition, the ribs may be associated with a corresponding structure on the inner wall of the open-check band to prevent the annular retaining band from bending further in the downward direction.

In an additional preferred embodiment of the present invention, the axial length of the opening-indication band (i.e. the distance between the weakened line and the lower edge of the band) is shorter than the axial distance between the free edge and the lower edge of the open- The free edges of the flaps extend to the inner wall of the cylindrical skirt when the cap is in the tightened position.

When the cap cap is provided in the container, radial forces are exerted on the frangible connection between the skirt portion of the cap cap and the unsealing-display band, especially when the unsealing-indicator band passes over the retaining structure of the container All. At this time, the rupturable connection, for example a bridge element or a line of weakness, can prematurely break completely or partially. Thus, it is desirable that the tamper indicating ring be limited so that it can be bent outwardly around the line of weakness. When the extension is supported by the inner surface of the skirt, the lines of weakness are shielded from the radial forces exerted by the retaining structure.

According to a further aspect of the present invention, a combination of a container neck and a stop cap with an annular retaining band, preferably a stop cap as described above, is provided. The container neck includes a retaining structure having at least one engaging surface and arranged in an outer perimeter.

When the stopper is opened, the engagement surfaces of the projections arranged on the retaining band of the stopper are engaged under one or more engagement surfaces of the retaining structure, while the distal areas and free edges of the flaps are engaged with the inner surface of the stopper Clamped between the retaining structures of the container.

The present invention will now be described more specifically by way of example with reference to the accompanying drawings.
1 is a first perspective view showing an example of a cap according to the present invention.
2 is a bottom view of the stopper.
3 is a side view of the stopper.
4 is a second perspective view of the stopper.

Fig. 1 shows a first embodiment of the cap cap 101. Fig. The stopper cap 101 includes an upper panel 102 and a cylindrical skirt 103. At the lower end of the cylindrical skirt 103, the unsealing-indicator band 104 with the lower edge 106 is frangibly connected.

2 is a bottom view of the plug 101. Fig. An annular retaining band 105 extending over the entire circumference is hingedly connected to the lower edge 106 of the unsealing-indicator band 104.

In all the drawings showing the plug 101, the retaining band 105 is arranged in a downward direction and is molded. The retaining band 105 can be folded later to be stably arranged in the upward direction.

The retaining band 105 is directed toward the upper panel and extends radially inward when the cap is in a screwed on position.

An annular retaining band 105 comprises a plurality of circumferential portions 107 having the same circumferential length 108, the circumferential portions 107 being arranged such that each portion forms a flap 111, Which are separated from each other.

Figure 3 is a side view showing the cap 101 before capping. Each flap 111 is configured such that when the cap 101 is in the closed position the free edge 113 extends at least axially above the engagement surface of the retaining structure arranged on the container neck And has a maximum axial length 112 selected to be inserted between the retaining structure and the skirt 103 when the cap 101 is provided in the container.

The outer circumferential portions 107 of the annular retaining band 105 each have two protrusions 109 with a plug engagement surface 110 which are positioned such that when the cap 101 is in the tightened position And extends radially toward the interior of the cap 101 to engage under the engagement surface of the retaining structure.

The maximum axial length 112 of the flap 111 is longer than the axial distance 119 between the closure engagement surface 110 and the lower edge 106 of the unsealable display band 104.

4 is a second perspective view showing the stopper 101. Fig. The outer circumferential portions 107 of the annular retaining band 105 have holes 120 between the protrusions 109 on the outer circumferential portion 107, respectively. The holes 120 are circumferentially abutted with respect to the adjacent projections 109. [ The axial extensions of these holes 120 are shorter than the axial extension 119 of the projection 109.

Connective elements 114 are arranged between adjacent protrusions 109 on the outer circumferential portion 107 and the connecting elements 114 are aligned parallel to the plug engagement surface 110 of the adjacent protrusions 109, And has a mating surface 118 that connects to surface 100.

The distance 115 between adjacent protrusions 109 on the outer circumferential portion 107 is equal to the distance 116 between adjacent protrusions 109 on the different circumferential portion 107.

The adjacent outer circumferential portions 107 are separated by a V-shaped gap 117 such that the circumferential portions 107 generally have a trapezoidal shape. There is no hole between the lower edge 106 of the unsealing-indicator band 104 and the gap 117. The axial length of the V-shaped gap 117 is shorter than the maximum axial extension 112 of the annular band. However, the distance between the lower edge 106 of the unsealing-indicator band 104 and the gap 117 is shorter than the axial length 119 of the projection, which in turn means that the axially extending portions of the gap are in the axial direction of the projection Is longer than the difference between the length 119 and the maximum axial length 112 of the outer circumferential portion 107.

The protrusion 109 has a wedge shape in which the radial thickness is increased each time the distance of the lower edge 106 of the opening-confirming band 104 is increased.

The outer circumferential portions each have at least one outer circumferential rib 121 on the radially inner surface. Since the retaining bands 105 are arranged in the downward direction in the figure, the outer circumferential ribs 121 extend radially toward the inside of the stopper cap. However, the outer circumferential ribs 121 extend radially outwardly toward the open-close band cap 101 when the cap 101 is in the closed position.

Although one exemplary embodiment is shown in Figs. 1 to 4, the present invention is not limited to the above embodiments. In particular, certain alternative examples of elements shown in the drawings are still within the scope of the present invention. For example, the number of protrusions or peripheries may be selected according to the requirements of the present invention.

Typically, there are approximately 14 protrusions and seven circumferential portions.
