Abstract

A closure for a container (10) having a dispensing nozzle (22) include a central aperture to receive the nozzle. In one embodiment, the nozzle extends through the aperture (40) and projects upwardly from the base cap (32). The base cap further includes a top wall inclined with respect to the central axis of the base cap to assist in dispensing of the contents of the container. A cap lid (34) is hinged to the base cap by a snap hinge assembly.

Description

The invention relates to a closure for a clamp tube, as stated in the introduction in claim 1.

It is usually preferred that ordinary containers, such as clamp tubes, have a snap-on so that it is easy to open and close the container. In this way, the cap that closes the container after use is not separated from the containers. When the cap is separated from the container, there is a risk that it can get lost. Thus, it is desirable that the cap is kept fixed on the container when the product is dispensed from the tube. This type of closure is often called a hinged hood.

Dispensing containers and closures are often used in connection with viscous materials, e.g. toothpaste. Special problems often arise in connection with toothpaste that are not present in other materials. One such problem in connection with the storage of toothpaste is that the container must have a barrier layer to prevent flavor components and oils from being absorbed. Since the closed° remains in contact with the toothpaste for a longer period of time, it is important to minimize the surface area of the cap touching the toothpaste.

The type of closure usually preferred by the consumer is the one where the closure is connected to a bottom by means of a snap hook. This form of closure typically has a hinge where the closure will be biased to an open position during dispensing and otherwise biased to a closed position. Although biased to a closed position when the product is not being dispensed, some manual force is usually required to snap the cap to the bottom to completely close the tube and seal the outlet opening.

Closures of a type with a snap lock have been used for many years. One of the earliest closures of this type is shown in US-PS 1,928,445 which describes a rubber hinge connecting a cap to a base. The bottom is a threaded round element attached to a threaded dispensing outlet for a tube. The cap part is hinged to the bottom and can be manipulated from a closed position to seal the tube's outlet to a fully open position. This closure has a rubber film hinge attached to a base and cap which will bias the cap either in an open position or in a closed position.

Another form of a hinged cap for a tube is shown in US-PS 3,933,271. This cap has a bottom portion attached to the tube and a cap portion connected to the bottom by means of a snap hook. When the hood is opened to a point less than the middle position, the hood is biased towards closing. When the hood is swung open past the middle position, the hood is biased open. The design of the hinge ensures this special effect.

Another type of film hinge for use in connection with a closure is shown in US-PS 4,403,712. This closure has the property that the cap part is either biased open or closed. The hood also has the advantage that when the hood is in the closed position, the film hinge is located within the hood's profile. Another type of closure with a snap is shown in US-PS 4,503,991. This is a two-piece snap that connects the cap to the base. The part of the closure that seals the dispensing opening for the container has a protrusion that fits down into the dispensing opening. The use of a double hinge means that this snow pick has increased usability.

US-PS 4,615,462 describes another example of a snap pick. The hinge comprises a main link and two secondary links. The main joint stabilizes the cap and the bottom part while the secondary joints produce the snap action. This is not a film hinge and the hinge parts will not be within the hood's profile in the closed position. US-PS 4 854 473 describes a similar closure where the hinge also consists of three parts. In this closure, the hinge also consists of three parts and will be within the bottom cap's profile when the cap lid is in the closed position.

These patents show the current situation for snap-hinged closures for tubes. However, there is not shown a closure suitable for use with a tube with a tip, or having an outlet for dispensing a product located adjacent to the centerline of the tube. Furthermore, there is not shown a cap with a snap-on which is so large that the tube can stand on the cap and where the surface of the dispensing part of the cap is chamfered for easier delivery of the product. The latter property is important when it comes to toothpaste that is dispensed on a brush. This makes it easier to apply the product to the brush. Another advantage is that the hood can be used as a hinged hood or as a removable hood and thus satisfy several users.

The purpose of the invention is to provide a closure for a clamp tube which has the above-mentioned properties. According to the invention, this purpose is achieved by the closure having the characteristic features as stated in claim 1. Advantageous embodiments are

stated in the independent requirements.

The invention will be described in more detail below in connection with some embodiments and with reference to the drawings, where fig. 1 shows a cross section of closed and a tube with a dispensing tip, fig. 2 shows a cross-section of the closed in fig. 1, fig. 3 is a top view of the closed in fig. 1 in the open position, fig. 4 shows a cross-section of closed according to a second embodiment and shows the delivery channel displaced from the center line of the tube, fig. 5 is a top view of the closed in fig. 4, fig. 6 shows a cross-section of an alternative embodiment of the invention showing the hinge assembly, fig. 7 is a partial side view of the top cap of FIG. 1 in the closed position, fig. 8 shows a cross-section of another alternative embodiment of the invention and shows the cam arrangement, fig. 9 shows a cross-section of yet another alternative embodiment and shows an annular rib in the bottom cap which fits into an annular groove in the tip.

The disadvantages and limitations in connection with previous closures are avoided by the invention by an effective and simple closure for a dispensing container. In a preferred embodiment of the invention, closed is used in connection with a dispensing container, e.g. a compressible tube, a flexible squeeze bottle or other container with an optional pump or valve device. The container preferably has a dispensing tip with internal threads which can be connected to a closure.

The invention is partly directed to a closure in connection with a clamp container, e.g. as the tube 10, comprising a bottom cap 32 and a top cap 34.

With reference to fig. 1, the tube 10 comprises a side wall 12 which delimits the body of the tube. The shape of the tube resembles a normal squeeze tube which collapses as the contents of the tube are dispensed. The tube has a general circular cross-section and is closed at the bottom by a straight seam 14. Typically, the tube is made of a flexible plastic film material, although other materials, e.g. metal foil can be used. When the tube is made of a plastic material, the bottom seam 14 is made by welding.

The container and closed according to the invention is particularly suitable for use when dispensing toothpaste and gel materials. The container preferably has a barrier layer on the inside of the container to prevent absorption of flavor components and oils from the toothpaste. The tip of the container will typically have a barrier layer as the tip is usually made at the same time as the tube. The closed arrangement, which will be described in more detail below, has minimal contact with the toothpaste and does not include a barrier layer.

The tube 10 also has a top part which forms an inclined, conically shaped shoulder 16. Towards the tip of the shoulder 16 there is a dispensing tip with a cylindrical part 18 placed concentrically in the central axis of the tube and extending upwards from the shoulder 16. Several threads 20 are arranged on the outer surface of the cylindrical part for connection to closed 32 as mentioned below. A tapered dispensing nozzle 22 extends from the axial end of the cylindrical portion 18 to form an outlet 24 from the tube. Between the tip 22 and the cylindrical part there is an annular groove 26. In the embodiment in fig. 1, the tip 22 has a substantially conical shape with a slightly concave side, although alternative embodiments of the tip may have a truncated conical shape with straight walls. The tip 22, the cylindrical part 18 and the shoulder 16 are integrally made with the tube 10 in the preferred embodiments. In alternative embodiments, the tip 22 and the cylindrical part 18 can be manufactured in one unit and attached to the tube 10 by means of welding or gluing.

The tip 22 as shown in fig. 1, is concentric with the central axis of the tube 12 and extends from the end of the tube at a distance sufficient for easy dispensing of the tube's contents. The tip 22 preferably extends from the shoulder 16 of the tube approximately 0.75 - 2.0 cm. The dispensing outlet 24 from the tip 22 generally forms an annular axial opening having a diameter of about 3 mm to about 10 mm. The dimension of the outlet 24 is generally not critical as long as the contents of the tube can be easily dispensed by squeezing it. The tip 22 enables the tube's contents to be dispensed some distance from the tube's normal delivery point.

The closure 30 according to a first preferred embodiment comprises a bottom cap 32 and a top cap 34 hinged to the bottom cap. The bottom cap 32 has a generally cylindrical shape as shown in fig. 2 and 3. The bottom cap 32 has an outer cylindrical wall 36 down from the upper wall 38. The outer wall 36 in preferred designs has the same size as the outer diameter of the tube 10 so that when the bottom cap 32 is placed on the tube 10, the outer wall 36 will be substantially flush with the tube's wall 12.

In the embodiment in fig. 1, the upper wall 38 has a central opening 40 coaxial with the central axis of the bottom cap 32. The opening 40 forms an annular lip 42 which projects radially inward towards the center of the bottom cap 32. In alternative embodiments, the annular lip may be located slightly below the upper edge of the bottom cap and be interrupted by several depressions. In preferred embodiments, the annular lip 42 may be substantially perpendicular to the central axis of the bottom cap. Most of the upper wall 38 forms an inclined surface 44. An edge 46 extends around the circumference of the inclined surface 44 which fits the edge of the outer cap 34.

An inner, ring-shaped wall 48 extends from the underside of the upper wall 38 and is concentric with the center axis of the bottom cap. In preferred embodiments, the inner wall 48 stands straight inward from the outer wall 36. In the embodiment shown in fig. 1 and 2, the inner wall 48 has a length which is slightly smaller than the length of the outer wall 36. Internal threads 50 are provided on the inside of the inner wall 48 and match the threads 20 on the tube 10.

The bottom cap 32 is placed on the tube 10 so that the tip 22 extends from the central opening 40 in the bottom cap 32, so that the threads 50 will fit with the threads 20 on the tube. The bottom cap 32 is then screwed onto the tube until the tip 22 extends completely through the opening 40 and the lower edges of the inner wall 48 and the outer wall 36 grip the shoulder 16 of the tube 10. When the bottom cap 32 as shown in fig. 1 and 2, is completely placed on the tube 10, the lip 42 of the central opening 40 in the bottom cap 32 will be clamped in place in the annular groove 26 in the tip 22. Preferably, the lip 42 forms a tight fit against the tip 22. The clamping connection between the lip 42 and the groove 26 prevents the bottom cap from being unscrewed from the tube. The bottom cap 22 can be removed from the tube by manually unscrewing the bottom cap so that the threads 20 and 50 force the bottom cap 32 away from the tube until the lip 42 snaps free from the groove 26.

The outer top cap 34 is connected to the bottom cap by means of a hinge 52. The outer top cap 34, as shown in fig. 2, has a cylindrical outer wall 54 which fits the outer dimension of the bottom cap 32, so that the walls 54 and 36 are flush with each other when the top cap 34 is closed. The outer wall 54 of the top cap 34 ends in a lower end 56 which is chamfered in relation to the central axis of the top cap 34 and completes the edge 46 of the bottom cap 32. A top wall 58 connected to the outer side 54 defines an upper edge 60 which is substantially perpendicular to the axis of the top cap 34. An annular collar 62 extends down from the inner surface of the top wall 58. The collar 62 is concentric with respect to the central axis of the top cap. An internal, ring-shaped collar 64 is placed on the inside of the collar 62. The collar 62 will touch the outer surface of the tip 22 while the collar 64 touches the inner surface. Preferably, the collars 62 and 64 form a snap connection with the tip 22.

The closure 30 is assembled at the tip as shown in fig. 1, by screwing the bottom cap 32 onto the threads 20 of the tip, until the tip 22 passes through the opening 40 and the lip 42 is received in the groove 26. In preferred embodiments, the tip 22 is dimensioned so that it extends over the lip 42 approximately 0.2 - 1, 5 cm. The top cap 34 is hinged to the bottom cap 32 and closes the tube. The annular collar 62 on the top cap 34 grips the outer surface of the tip 22 and forms a substantially fluid-tight seal. The inner surface of the outer side 54 of the top cap 34 has hooks 66 on the side part and hooks 67 on the front side which snap against each other over beads on the ledge 46 of the bottom cap 32 and projections 68 to hold the top cap 34 in the closed position. Also, the raised portion 73 on the side 71 near the hinge serves to force the rear side of the top cap 34 outwards when closed, so that the hook 67 locks more securely into the projection 68 of the bottom cap 32. The edge of the bottom cap 32 and the top cap 34 have a recess respectively 69 and 70 which make it easier to open the top cap 34.

When it is desired to dispense the contents of the tube, the top cap 34 is screwed to the open position and a dispensing force is applied to the side of the tube to force the contents through the tip. The tip 22 extends a little way from the bottom cap to make it easier to dispense the product. The top side 58 of the top cap 34 is chamfered at an angle of about 5° - 15° and preferably about 10° from the axis of the bottom cap, for easier dispensing from the tube. The top side 58 of the top cap 34 is slightly concave and dimensioned so that the tube 10 can stand upright on top. This means that the tube can stand upright when it is not in use so that it does not take up too much space. The closure can be used by sliding the top cap to the open position or alternatively by unscrewing the closure from the tube as with normal screw caps, to accommodate personal wishes from the consumer.

The top cap 34 is attached to the bottom cap 32 by means of the hinge assembly 52. The bottom cap 32 has a curved wall 71 near the hinge 52 which extends upwards from the outer side 36 over the top side 44. As shown in fig. 3, the wall 71 has two step portions 72 and 74 adjacent to a higher step portion 76. A primary stabilizing hinge 78 connects the step 76 to the top cap 34. A pair of snow pick elements 80 and 82 are connected between the steps 72 and 74 and the top cap 34. Each snow pick element has an elongated part 84 with side edges 86, 88 which are vertically positioned in relation to the bottom cap when the top cap 34 is closed. The ends of the elongated part 84 are connected to the respective the step 72 and the top cap to form the hinges 90 and 92. Each snap hinge 80, 82 is made in a similar manner.

The arrangement of the hinges 78, 80 and 82 gives a smooth appearance when the outer cap is closed so that the hinges are substantially flush with the side walls 36 and 54 as shown in fig. 7. During use, the top cap 34 pivots in relation to the bottom cap 34, around the center hinge 78 which forms the axis of rotation for the top cap. As the snap hinges 80 and 82 are placed some distance from the center hinge 78 along the edge of the bottom cap, the hinges 80 and 82 will provide a snap effect over the middle. When the top cap 34 is swung away from the bottom cap past the point where the snap hinges 80 and 82 are in the same plane as the center hinge 78, the top cap will snap into the open position. Likewise, when the top cap is swung towards the bottom cap past the same point, the top cap will snap into the closed position.

This closure is not limited to a particular hinge type. This can be of the wooden band type as shown in the drawings, or it can be a film hinge as shown in US-PS 4 403 712. In a further embodiment of the invention as shown in fig. 4 and 5, the tube 100 has a flexible and compressible side wall 102 connected to a partially conical shoulder 104. A cylindrical part 106 extends from the shoulder 104 and is concentric with respect to the central axis of the tube 100. Threads 108 are provided on the outside of the cylindrical portion 106 to connect the tube to the closure 110. A tip 112 extends from the cylindrical portion 106 and is concentrically disposed with respect to the central axis of the tab. The upper end of the tip 112 has an outward facing radial lip which forms an annular groove 114.

The closure 110 comprises a bottom cap 116 and a top cap 118 connected together by means of a hinge 120. The bottom cap 116 has an outer, ring-shaped wall 122 down from an upper wall 124. The outer wall 122 has a dimension that matches the tube 100 dimension so that the outer wall 122 is substantially flush with the tube when placed on the tube. An inner wall 126 is placed on the inside of the outer wall and concentric with respect to the outer wall. The inner wall 126 has threads 128 that match the threads 108 on the tube 100 to attach the bottom cap to the tube.

The upper wall 124 delimits a conduit 130 arranged transversely in relation to the axis of the bottom cap 116. The conduit 130 in the upper wall forms a round inlet opening 132, which is concentric with respect to the axis of the bottom cap 116 and the inner and outer walls 126 and 128. As shown in fig. 4, a round collar 134 extends inward and is concentric with the inner wall 126. A lip 126 extends radially inward from the lower end of the collar 134. The conduit 130 terminates in an upwardly facing tip 138 that extends over the upper wall 124 of the bottom cap 116.

The conduit 136 as shown in fig. 4, forms an axial inlet channel 140, a substantially horizontal channel 142, and an axial outlet channel 144. The inlet channel 140 is placed coaxially with the inner wall of the bottom cap. The outlet channel 144 and the tip 138 are offset relative to the center axis of the bottom cap towards the peripheral edge to facilitate dispensing of the tube 100's contents. The upper wall 124 is preferably beveled in relation to the central axis of the bottom cap to further facilitate dispensing of the tube's contents. In the embodiment in fig. 4, the upper wall 124 slopes downward from the hinge assembly 120 to the opposite side of the cap. Preferably, the outlet tip 138 and the outlet channel 144 are placed opposite the hinge 120.

The outer wall 122 has a ledge 146 around the periphery of the bottom cap 116. A wall portion 148 extends over the upper wall 124 to support the hinge 120.

The top cap 118 is substantially similar to the top cap in the embodiment of fig. 1, except for the annular collar 150 which is located some distance from the center axis of the outer cap to accommodate the offset tip 138. An inwardly directed rib 152 engages the end of the tip 138 when the cap is closed to seal the outlet channel 144. Components of the outer cap 118 and the hinge 120 which has the same construction and function as the embodiment in fig. 1, is named with the same reference number with the addition of an apostrophe.

In use, the bottom cap 116 is placed on the threaded cylinder 116 on the tube 100. The bottom cap 116 is screwed onto the threads 128 to drive the bottom cap 116 to the resting position shown in fig. 4. Screwing down the bottom cap on the threads 128 will cause the lip 136 on the inlet collar 134 to be clamped into position in the groove 114 on the tip and provide a liquid tight seal. As shown in fig. 4, the upper end of the tip 112 is substantially flush with the lower side of the horizontal channel 142. In this embodiment, the end of the tip 112 is below the upper surface of the bottom cap 116. When the bottom cap rests on the tip, the contents of the tube can be dispensed by squeeze the sides of the tube and force the contents through the tip 112 and the channel towards the outlet tip 138. The top cap 118 which is connected to the bottom cap 116 by means of the snap lock is closed by the top cap 118 resting against the bottom cap. In the closed position, the edge of the top cap 118 will rest against the slanted edge of the bottom cap. The collar rests against the tip to seal the opening.

The embodiment in fig. 6 differ from those in fig. 1-4 in that the hinge between the bottom cap and the top cap is not raised above the bottom cap but is rather a continuation of the upper wall of the bottom cap. If the hinge used is a three-band hinge as shown in fig. 1-4, the two end bands can be attached to the bottom cap slightly below the upper wall of the bottom cap. This is a common construction for such a hinge where the hinge is essentially an extension of the upper walls. This design has some structural advantages compared to the design in fig. 1 - 3. In this embodiment, the hinge assembly 252 is essentially an extension of the upper wall 238. Down from the upper wall is a cylindrical wall 236. The tip of the tube extends through the central opening 240 formed by the annular lip 242. The top cap has a cylindrical wall 254 and an upper wall 258. Annular collars 262 and 264 are also shown. Hooks 266 and 267 hold the outer cap closed with hook 267 locked in projection 268. The hinge construction is essentially the same as in the embodiment in fig. 1-5.

Another embodiment is shown in fig. 8 and has a cam arrangement which secures the cap to the container. The tube 160 and closed 172 are similar to the design in fig. 1, except for the threads on the bottom cap and tip.

In the embodiment in fig. 8, the tube 160 has a conical shoulder 162 and a cylindrical collar 164. The axial end of the collar 164 has an annular groove 168 and a conical dispensing nozzle 170. The closure 172 has a bottom cap 174 and a top cap 176 secured together by a hinge assembly 178. The bottom cap comprises an upper wall 180, an inner downward-facing wall 182 and an outer downward-facing wall 186 in a similar manner to the embodiment in fig. 1. An axial opening 188 extends through the upper wall. An inwardly projecting annular rib 190 extends around the opening 188.

The inner wall 182 has an inner surface with cam elements 192 which are inclined in relation to the central axis of the cap. As shown in fig. 8, the comb elements have inclined surfaces. The cylindrical collar 164 of the tube has complementary cam elements 194. The cam elements 192 and 194 are integrally molded into the tube and cap, respectively. As shown in fig. 8, the comb elements act as ordinary threads to screw the bottom cap to the tube, so that the tip extends through the opening 188 and the rib 190 will snap into the groove 168 on the tip. The comb elements are sufficiently flexible, so that when the tip rests in the opening 188, further rotation of the cap in relation to the tip will cause the comb elements to snap past each other. Turning the closure counterclockwise will engage the cams 192 on the closure and the cams 194 on the tube which lift the closure and disconnect the rib 190 from the groove 168. When the rib 190 is separated from the groove 168 the closure can easily be unscrewed from the tip. The cam elements in this design allow the closure to be turned clockwise to any desired position on the tip without risk of overtightening, or for the bottom cap to be unscrewed from the tube.

A further embodiment of the invention is shown in fig. 9 and comprises a bottom cap 168' with a top cap 176' attached to a tube 160'. The bottom cap, the top cap and the tip have substantially the same construction as in the embodiment in fig. 8, excluding the fastening arrangement for connecting the bottom cap to the tube. Therefore, identical components are identified by the same reference number with the addition of an apostrophe.

In this embodiment, the bottom cap 186' is permanently attached to the tube by means of a snap connection, thus preventing the bottom cap from being removed from the tube during normal use. As shown in fig. 9, the inner wall 182' of the bottom cap has an annular locking rib 200 which extends radially inwards towards the central axis of the bottom cap. In the embodiment in fig. 4, the annular rib 200 is a continuous rib. In alternative embodiments, the rib 200 may be interrupted to form several hooks around the inner wall 182'

fleet.

The tube 160' has a conical shoulder 162' and a cylindrical collar 164'. The axial end of the collar 164' has an annular groove 168' and a dispensing tip 170'. An intermediate annular rib 202 is located near the center of the annular collar. The annular rib 202 has an inclined upper wall and is dimensioned so that it complements and can be locked together with the annular rib 200 in the bottom cap.

The bottom cap 186' is placed on the tube by pushing the tip 170' through the opening 188' in the bottom cap. The bottom cap is pressed downwards on the tip until the rib 200 snaps over the rib 202 and the annular rib 190' which delimits the axial opening in the bottom cap snaps into the groove 168'. In alternative embodiments, rib 190' and groove 168' can be eliminated when rib 200 and rib 202 are present. In all cases, the upper edge of the bottom cap will preferably form a seal against the tip to prevent dirt or the dispensed material from collecting between the bottom cap and the tip. The bottom cap can be removed from the tube by pulling the bottom cap away from the tube with sufficient force so that the ribs 190' and 200 snap from the groove 168' and the rib 202.

The closure in preferred embodiments is made of molded plastic material as a unit. Suitable plastic materials include e.g. polyolefins, e.g. polyethylene, polypropylene and copolymer. Typically, the caps are made by injection molding.

The tube is also made of suitable plastic material, e.g. polyolefins. In preferred embodiments, the tip, shoulder and body of the tube are molded as a unit. The tube and closed are particularly suitable for viscous materials, e.g. toothpaste, where only small amounts are dispensed at a time. The closure provides a practical and efficient device for attaching the closure to a tube, so that the tube can be closed after each use.

The cap can also be removed from the tube when the contents of the tube have been used up. The cap can be removed from the tip of the tube by turning the bottom cap in relation to the tube so that the threads are unscrewed from the bottom cap of the tube and release the lip in the bottom cap from the groove in the tip. That way, the closed can be used again on another tube.
