Description

DESCRIPTION

Cap for a screw neck container fitted with a coupling locking element

Technical field of the invention

The present invention relates to a cap for a screw neck container.

The invention more particularly relates to a cap that cannot be separated from the container even when the cap is opened.

Technical background

It is known that a screw neck container, such as a bottle, can be provided with a neck to which a cap is screwed on. The term "container" designates in this case all types of containers, without any limitation of form or use. The cap includes, for example, a cap body comprising a tubular shaped skirt and a plateau connected at its periphery to the skirt and adapted to cover the neck opening. The skirt includes a thread disposed on the inside, adapted to mate with a complementary shape of the neck of a container.

The skirt is often extended by an anti-tamper ring intended to mate with a neck collar. The tamper evident ring is connected to the skirt by bridges between which through gaps extend. During the opening of the cap, the tamper-evident ring remains attached to the collar and is separated from the skirt by breaking the bridges. This shows that the bottle has already been opened.

Recently, new European directives have introduced a standard that requires ordinary stoppers such as those described above to be connected to the neck of the bottle, in order to limit the impact of pollution on the environment through the discharge of these plugs.

Therefore, the development of certain containers will only be possible to the extent that their cap is attached to the rest of the container so that they are not separated, lost in nature and then ingested by animals.

It is in this context that we have seen the development of stoppers that cannot be separated from the container, regardless of its closing or opening state.

These inseparable plugs, referred to as new generation closures, comprise the same elements as conventional plugs, except that the plug body is permanently connected to the anti-tamper ring by means of the connecting arms. These connecting arms are shaped by their length to allow the cap body to move axially away from the anti-tamper ring and separate from the neck and can be tilted to an open position where access to the container is free.

Document US5215204 describes an example of an embodiment of this type of stopper.

However, the inseparable plug as described has the drawback that, once the plug body is in the open position, the connecting arms, in combination with the elastic force of the hinges, tend to return the plug body plug behind the neck opening. This creates a semi-open state of the container, that is, a state in which the neck opening is partially released. This semi-open state hinders the flow of liquid out of the container and forces the user to hold the cap body in an open position in which the neck opening is fully released.

Therefore, the object of the invention is to offer a cap that guarantees good sealing of the bottle and guarantees inviolability. This cap is comfortable to use and guarantees a comfortable use.

Explanation of the invention

With these objectives, the invention provides a cap for a screw neck container, comprising:

- a cap body comprising an essentially tubular skirt centered on a longitudinal axis and means for coupling it with the neck of the container, the cap body being pivotally mounted, around an axis of rotation transverse to the longitudinal axis , between a closed position in which the cap body closes a neck opening and an open position in which the neck opening is clear to allow access to the interior of the container;

- an anti-tamper ring centered on the longitudinal axis and comprising means for coupling it with a collar of the neck; Y

- two connecting arms extending in an angular direction, the connecting arms being connected, on the one hand, to the anti-tamper ring and, on the other hand, to the cap body through the hinges.

According to the invention, the cap comprises a locking element located between the two connecting arms. Furthermore, the blocking element comprises a first part connected to the cap body and a second part connected to the anti-tamper ring, the first and second parts being solid. Finally, the first part and the second part of the locking element are shaped to engage one another to allow the cap body to be held in a fully open position in which the cap body is completely disengaged. from the neck opening.

Note that the cap body is pivotally mounted between various open positions. In fact, the cap body can go from the closed position to a barely open position in which only a part of the neck opening is released, or to a maximum open position in which the inclination of the cap body with respect to to the anti-tamper ring is maximum. When the cap body is in the fully open position, it can also be said that the container is in the fully open position.

The fully open position can be an intermediate position between the slightly open position and the maximum open position. In general, the plug body is in a fully open position when you make an angle greater than 90 ° with the anti-tamper ring.

In the proposed cap, the object of the locking element is to keep the cap body in a fully open position. In particular, the first part and the second part of the locking element engage one another to keep the cap body offset from the neck opening so that it is completely clear.

Therefore, the circulation of the liquid is no longer hampered by the stopper body. Therefore, the plug is comfortable to wear. The user only has to open the cap until the cap body is immobilized by means of the locking element. You can then freely pour the liquid into the container without having to hold the stopper body.

Furthermore, by means of the blocking element, the cap guarantees the safety of use, since the cap body is no longer in a position to be able to retain a residual amount of the liquid after pouring. In other words, the cap body is kept dry and can be handled without affecting the closure of the cap.

According to other characteristics of the invention:

- the first part of the locking element is formed by an outwardly projecting flange; the second part of the locking element is formed by an island connected to the anti-tamper ring and comprising a groove to receive the flange to keep the cap body in the fully open position;

- according to the previous paragraph, the axial dimension of the groove is equal to or slightly less than the axial dimension of the flange, so that it is retained longitudinally by friction in the groove;

- in addition to the characteristic of the previous paragraph, the transverse dimension of the groove is equal to or slightly less than the transverse dimension of the flange so that the flange is retained transversely by friction in the groove; in other words, the groove and flange have complementary cross-sectional shapes to fit each other; this allows the cap body to be better held in the open position;

- alternatively, the flange can be retained only by its transverse sides; - the second part of the locking element has a variable thickness along the longitudinal axis, with the thinnest part forming the groove;

- according to the previous paragraph, the second part comprises, in the axial direction, a first part of increased thickness and a second part of increased thickness arranged on both sides of the groove, the thickness of the first part being different from the thickness of the second part;

- in another exemplary embodiment, the locking element comprises at least three tabs; a first longitudinal flange between the three flanges is arranged in one between the first part and the second part of the blocking element and the two remaining flanges are arranged in the other between the first part and the second part of the blocking element; finally, the flanges are arranged so that they are at least partially coupled with each other to keep the cap body in the fully open position;

- according to the previous paragraph, the two remaining flanges are separated transversely one with respect to the other a distance equal to or slightly less than the width of the first flange; furthermore, when the cap body is in the closed position, the first flange is aligned with the space between the two remaining flanges;

- according to the last two paragraphs, each flange comprises a radial external face connecting two lateral faces; furthermore, for each flange, the lateral faces comprise a rib extending longitudinally and located close to the outer face;

- each flange has two rounded longitudinal edges;

- each connecting arm is attached to the cap body by means of a corresponding hinge;

- according to the previous paragraph, each hinge is made up of a strip of thin material;

- alternatively, each hinge is formed by a clamping leg that extends directly from the cap body and with low thickness; the inclination of the cap body is carried out by bending the clamping leg;

- in this example, the thickness of the connecting arm is greater than the thickness of the clamping leg, so that the joint between the clamping leg and the connecting arm form a flexible zone;

- furthermore, the connection between the clamping leg and the connecting arm is inclined with respect to a horizontal plane in the direction of the second part of the locking element;

- the cap body, the anti-tamper ring and the locking element are formed in a single monobloc piece.

Detailed description of the invention

Figures 1 to 5 show a first example of embodiment of the cap according to the invention. Figures 6 to 10 show a second embodiment example of the cap according to the invention. The plugs according to the first The example and the second example are to be mounted on the neck 31 of a container. Neck 31 and container 3 are illustrated in Figures 12 and 13.

In FIG. 1, the cap 1 according to the first exemplary embodiment comprises a cap body 10 and an anti-tamper ring 11.

The cap body 10 in this case includes a lateral skirt 101 in the shape of a right cylinder with axis of revolution X-X '. Said axis is considered the longitudinal axis of the plug 1. The side skirt 101 comprises ribs 103 that all extend along the longitudinal axis XX 'and are uniformly distributed over the entire external face of the side skirt 101. Therefore, these ribs 103 allow the user's fingers to better engage the cap body 10 when gripping the cap body 10 to open or close the cap 1.

The cap body 10 further comprises a land 102 oriented perpendicular to the longitudinal axis X-X 'and connected at its periphery to the side skirt 101. The land 102 thus forms the bottom of the cap 1.

In a known manner and as illustrated in Figure 13, the cap body 10 further comprises the helical ribs 108 that are intended to engage with complementary helical ribs 34 that are formed on the neck 30 of the container 3. The helical ribs 108 of the Cap body are formed on an inner face of the side skirt 101.

The anti-tamper ring 11 is located in the extension of the lateral skirt 101 of the cap body 10. The anti-tamper ring 11 is connected to the cap body 10 through the connection arms 12, in this case a total of two, which are connected , in turn, to the cap body 10 by means of the clamping legs 14.

Furthermore, prior to the first opening of the cap, the cap body 10 is connected to the tamper-evident ring 11 by breakable bridges that are distributed around the circumference of the cap. The breakable bridges are shaped to break when the cap body 10 is rotated relative to the tamper-evident ring 11.

In the example shown, the connecting arms 12 are formed in the anti-tamper ring 11. For this purpose, an angled recess 113 is made in the ring 11 to form a lower part 111 and an upper part 112 separated by recess 113. The lower part 111 is intended to be attached to a neck collar, while the upper part 112 forms the connecting arms 12. The junction between the lower part 111 and the upper part 112 marks the end of the angular recess 113.

In this case, the angular recess 113 is continuous and the connecting arm opens into an upper face of the anti-tamper ring 11.

In accordance with the invention and according to this example, the cap body 10 is pivotally mounted with respect to the anti-tamper ring 11 between a closed position and at least one open position.

In the closed position, the land 102 of the cap body 10 is horizontal and located just above an opening 30 of the neck 31 to close this opening completely. In this case, the terms "horizontal" and "vertical" are defined with a cap mounted on a container that is standing upright on a flat surface. The container is held upright along a vertical axis. The horizontal direction is perpendicular to this vertical axis. The cap 1, as illustrated in figure 1, is in the closed position.

In an open position, the plateau 102 of the cap body 10 no longer covers the entire opening 30 of the neck, which makes it possible to release this opening 30 and, therefore, access to the interior of the container. Therefore, in the open position, the cap body 10 allows the liquid from the container 3 to be poured.

The cap body 10 can be tilted between various opening positions, among which is the fully open position, in which the cap body 10 is off-center with respect to the neck opening and is outward with respect to to container 2, to expose opening 30. Figure 13 shows an example of the fully open position of the cap body 10.

Furthermore, the cap body 10 can also be in a maximum opening position in which the inclination of the cap is maximum. In this case, in the maximum open position, the cap body 10 is rotated 180 ° with respect to its closed position, as can be seen in Figure 14.

The rotation of the cap body 10 is effected by means of the hinges 15 which will be described later. The axis of the hinges 15 constitutes the axis of rotation. The transverse direction is defined as the direction that is essentially parallel to the axis of rotation.

According to the invention and as illustrated in this example, the cap 1 comprises a locking element 13 is arranged between the two connection arms 14 and serves to keep the cap body 10 in a fully open position, and specifically in this case in the maximum open position.

As illustrated in figure 1, the locking element 13 comprises a first part 131 connected to the cap body 10 and a second part 132 connected to the anti-tamper ring 11.

The first part 131 is formed by a flange that extends radially outward. This flange also extends along an angular direction, perpendicular to the longitudinal axis X-X ', to form in this case a projecting band of parallelepipedic shape.

The second part 132 is formed by an island with an essentially rectangular shape. The second part 132 has a variable thickness along the longitudinal direction that is parallel to the axis X-X '.

In this case, the thickness is measured along the radial direction, the length is measured along the longitudinal direction, and the width is measured along the transverse direction.

More precisely, as illustrated in Figure 2, in a bottom-up direction, the thickness of the second portion 132 decreases and then increases again as it approaches an upper end 137 of the island.

In the longitudinal direction, the thinner part 133 of the second part 132 lies between a first part of increased thickness 134 and a second part of increased thickness 135. The transition zone between the thinner part 133 and each of the parts first and second 134 and 135 are manufactured smoothly with rounded surfaces.

In this case, the first part 134 is located at a lower level than the second part 135. Furthermore, the thickness e3 of the first part 134 is less than the thickness e4 of the second part 135.

According to the invention and as in the first example, the thinnest part 133 of the second part 132 forms a groove intended to receive the flange 131.

The flange 131 engaged in the groove 133 makes it possible to keep the cap body in a fully open position, and specifically in the maximum open position. Figure 3 shows the engagement of the flange 131 in the slot 133.

In this position, an external face 136 of the flange abuts against a bottom 137 of the slot 133.

The length l1 of the groove 133 is approximately equal to the length l2 of the flange, so that an upper edge 138 of the flange is in edge-to-edge contact with the transition zone between the groove 133 and the second part 135 Likewise, a lower edge 139 of the flange is also in edge-to-edge contact with the transition zone between the slot 133 and the first part 134.

In this way, the flange 131 is held in the groove 133 by friction in the longitudinal direction. This coupling allows the cap body 10 to be kept in the maximum opening position, as illustrated in Figure 3.

Optionally, the flange 131 and the groove 133 can be dimensioned such that the width p1 of the groove is equal to or slightly less than the width p2 of the flange. In this way, the flange 131 and the slot 133 have complementary sections that allow the adjustment of the flange 131 in the slot 133, which guarantees a more solid hold between these two elements.

As described above, the cap body 10 rotates with respect to the tamper-evident ring 11 by means of the hinges 15.

In this case, each connecting arm 12 is connected to the cap body 10 by means of a corresponding hinge.

According to the first example, each hinge 15 is formed by a clamping leg 14 that extends directly from the cap body 10. Each clamping leg 14 has a small thickness e6 that allows bending thereof, which gives place to the rotation of the cap body 10.

Each clamping leg 14 is attached to its corresponding connecting arm 12.

Furthermore, as illustrated in Figure 2, the thickness e5 of the connecting arm 12 is greater than the thickness e6 of the clamping leg 14. Therefore, the joint between the connecting arm 12 and the clamping leg 14 forms a flexible zone 16. The presence of this flexible zone 16 gives more mobility to the cap body 10, which facilitates the manipulation of the cap body when opening or closing the cap. This also allows the flex zone to be clearly marked, which is important for the placement of the flange 131 in the slot 133.

In Figure 5, each connecting arm connects to clamping leg 14 at its first end 121 and tamper-proof ring 11 at its second end 122. The two ends 121 and 122 are angularly offset from each other.

In this example, the first end 121 of the connecting arm 12 is constituted by a face inclined with respect to the horizontal in the direction of the locking element 13. The first end 121 is inclined at an angle of 45 ° with respect to the horizontal. In other words, the face that forms the first end 121 and a beveled face in the direction of the width of the connecting arm 12. This beveled face makes it possible to avoid the initiation of tearing when the hinge is loaded, thereby increasing the resistance to tear.

Furthermore, the side skirt 101 ends at the bottom with a bottom flap 104. Viewed from above, the bottom flap 104 forms an open circle with two free ends 105.

The locking element 13 and the clamping legs 14 are arranged in the space separating the two free ends 105 of the flap 104.

In accordance with the invention and as in this example, the free ends 105 of the flap are positioned at a distance from the clamping legs 14 to form a first longitudinally extending through space 19 between each free end 105 and the side outside 141 of the corresponding clamping leg 14. In this case, the outer side 141 of a clamping leg 14 is the one that is furthest from the flange 131 in the transverse direction.

On the other hand, the lower flap 104 is positioned above and separated from the connecting arms 12 to form a second through space 17 of angular extension.

The bottom flap 104, the clamping legs 14, and the connecting arms 12 are arranged so that the first through space 19 empties into the second through space 17 to form a resulting continuous through space 18 that is L-shaped. In other words , the first through space 19 and the second through space 17 meet and in this case form a right angle.

This particular arrangement allows for a strong bond between the cap body and the tamper-evident ring, while allowing a high degree of flexibility in the inclination of the cap body.

Figures 6 to 10 show a second embodiment example of the cap according to the invention.

In this second example, the cap 2 is formed by a cap body 20 and an anti-tamper ring 21. The cap body 20 of the cap of the second example is similar to that described in the first example.

The anti-tamper ring 21 also comprises two connecting arms 22 that connect this ring 21 to the cap body 20. Precisely, each connecting arm 22 is attached to the cap body 20 by means of a hinge 25.

The cap body 20 is pivotally mounted with respect to the tamper-evident ring 21 by means of these hinges 25.

In this case, each hinge 25 is formed of a band of thin material that can be folded back on itself to allow the cap body 20 to rotate about the axis of the hinge. Figure 10 shows the sectional view of one of the two hinges 25.

As seen in Figure 10, the thickness k1 of the hinge 25 is less than the thickness k2 of the connecting arm 22 and the thickness k3 of the cap body 20.

In the same way as the first example, the cap body 20 in the second example rotates from a closed position illustrated in Figure 6 to a maximum open position shown in Figure 15.

In this case, in the maximum open position, the cap body 10 is rotated 180 ° with respect to its closed position, as can be seen in figure 15.

According to the invention and as in this example, the cap 2 comprises a locking element 23 arranged between the two connecting arms 22.

It is clear from Figures 6 and 7 that the locking element 23 consists of a first part 231 connected to the cap body 20 and a second part 232 connected to the anti-tamper ring 21.

In this case, the first part 231 comprises a parallelepiped-shaped tongue that extends from the cap body downwards, that is, in the direction of the ring 21. The first part 231 further comprises three flanges 2311, 2312 and 2313 which are arranged on the tongue and protrude radially outward. These three flanges 2311, 2312 and 2313 extend along the longitudinal axis X-X '. Hereinafter, they will be referred to as the upper lashes.

On the other hand, the second part 232 of the locking element also comprises a tab that extends from the anti-tampering ring upwards, that is, in the direction of the cap body 20. The second part 232 also comprises two tabs 2321 and 2322 which are disposed on the tongue and extend radially outward. The flanges 2321 and 2322 of the second part 232 also extend along the longitudinal axis. X X '. In order to distinguish them from the upper lashes, the second part lashes are referred to as the lower lashes in the following description.

In this example, the top tabs 2311, 2312 and 2313 have the same shape. Likewise, the lower flanges 2321 and 2322 have identical shapes. The common point between the upper and lower flanges as regards their shape is that they all have the shape of a parallelepipedic block that includes an outer radial face 234 connecting two lateral faces 235, as illustrated in Figure 8.

Furthermore, on each of the upper and lower flanges, each side face 235 comprises a rib 233 that extends along the longitudinal axis X-X '. The rib 233 is located near the outer radial face 234 and serves as a connection between the outer radial face 234 and the corresponding lateral face 235. In other words, the upper and lower flanges each include two ribs 233 that form a protrusion on either side of the flange in question.

Furthermore, each upper or lower flange has a rounded upper axial edge 236 and a rounded lower axial edge 237.

In accordance with the invention and as in this example, the locking element 23 is arranged so that the upper flanges 2311, 2312 and 2313 and the lower flanges 2321 and 2322 engage each other when the cap body 20 is in contact. in a fully open position and to maintain the cap body 20 in the fully open position.

For this purpose, in the illustrated example, when the cap body 20 is in the closed position, the upper flanges 2311, 2312 and 2313 and the lower flanges 2321 and 2322 are angularly offset from each other so that a bottom flange is aligned with the gap between two adjacent top flanges.

Specifically, as seen in Figures 6 and 7, the first lower flange 2321 is aligned with the space E11 that separates the first upper flange 2311 and the second upper flange 2312. Next, the second lower flange 2322 is aligned with the space E12 that separates the second upper flange 2312 and the third upper flange 2313.

The same is true of the second upper flange 2312 which is in line with the space E2 between the first lower flange 2321 and the second lower flange 2322.

Furthermore, the width of the space E11, E12 between the adjacent upper flanges is equal to the width d1 of the lower flange aligned with this space. The spaces E11 and E12 are the same width because the bottom tabs have the same dimensions.

Similarly, the width of the space E2 between the lower flanges is equal to the width d2 of the second upper flange 2312.

The upper and lower flanges arranged in this way allow the flanges to be engaged with each other to maintain the cap body in the fully and fully open position.

Specifically, as illustrated in Figure 9, each second part lower flange 2321 or 2322 engages in the space between two adjacent upper flanges 2311 and 2312 or 2312 and 2313. Similarly, the second upper flange 2312 engages in the space between the two lower flanges 2321 and 2322.

The arrangement of the flanges causes the flanges to remain engaged by friction, or in other words, by adjustment, in their specific space.

In addition, once the flange is fully engaged in the reserved space, the ribs 233 add to friction retention to prevent that flange from slipping out of the space.

Note that during insertion of the flange into the corresponding space, the flange is elastically deformed to conform to the restricted portion 238 of the space formed between two ribs 233 that are positioned opposite each other. This restricted part 238 can be seen in Figure 8.

Furthermore, in the same way as the cap 1 of the first example, when the cap 2 of the second example is in the closed position, the cap body 20 is separated from the anti-tamper ring 21, specifically from the connecting arms 22, by an L-shaped gap 28. As illustrated in Figure 6, this L-shaped gap 28 is the combination of a first gap 26 between the flap 204 and hinge 25 with a second space 27 separating flap 204 and connecting arm 22.

Figures 11 to 15 illustrate the different stages of opening the cap 1 or the cap 2 described above. In these figures, the locking element 13 or 23 is not illustrated in detail.

In this case, it is the first opening of the cap.

The following description is carried out on the cap 1 of the first example. However, it applies in the same way to plug 2 of the second example.

In figure 11, the cap 1 is completely closed. The cap body 10 is in the closed position. Breakable bridges, not shown in the figures, connect the cap body 10 to the tamper-evident ring.

To open the cap, the user performs a first stage during which he grasps the cap body 10 with one hand and the container 3 with the other hand. The user then rotates the cap 10 in the direction indicated by the arrow R in Figure 11. As a result of this action, the breakable bridges are broken, indicating that the cap or container has already been opened. The cap body 10 is now released from the tamper-evident ring 11.

In the next stage, the user lifts the cap body 10 axially away from the tamper-evident ring 11, as illustrated in Figure 12. The connecting arms 12 gradually bend as the cap body 10 is raised. of the connection arms 12 allows this removal of the cap body 10 from the anti-tampering ring.

The user then rotates the cap body 10 out of the container 2 by rotating it around the axis of the hinges 15. The cap body 10 reaches a fully open position, as illustrated in Figure 13.

Finally, in the illustrated example and as shown in figure 14, the cap body 10 continues to rotate until reaching the maximum opening position that will be maintained by the locking element 13.

By performing the same steps on the cap 2, the cap body 20 of the cap also reaches its maximum opening position shown in figure 15. The cap body 20 is held in this position by the locking element 23.

Caps 1 and 2, described by way of illustration of the scope of the invention, have several advantages. The caps guarantee the hermetic closure of the container, at the same time that they indicate the state of use of the container, whether it is already open or not. The caps, by means of their respective locking elements, are kept open and completely release the opening of the neck so as not to hinder the circulation of the liquid. Finally, by remaining in the fully open position, the cap, specifically the cap body, will not be in contact with the liquid exiting the container and will remain dry during and after the liquid is poured.
