The present specification generally relates to devices and systems for dispensing material and, more specifically related to devices and systems for controlled dispensing of an adhesive from a tube.
Deformable tubes (for example, aluminum tubes) are often used for containing and dispensing materials, such as viscous liquids and gels, including, for example, adhesives. It can be difficult, however, to regulate the flow of materials out of deformable tubes. Dispensing material from them can be imprecise and messy, resulting in wasted material. In addition, the user may not squeeze the tube in the correct area, resulting in some of the material remaining trapped in the tube.
Various dispensing devices have been developed to provide a controlled delivery of materials, such as viscous liquids and gels, from deformable tubes. Typically, these devices comprise a container or casing surrounding the tube with buttons or jaws on the container or casing, which are manipulated to press against the deformable tube to dispense the viscous material. Often, however, these devices include multiple parts that are relatively expensive and complicated to manufacture and/or assemble. Additionally, in many instances, the devices are not capable of dispensing all or even most of the contents of the tubes, resulting in wasted material that the consumer cannot utilize.
Accordingly, the need still exists in this art for a device that dispenses a precise amount of a material, such as a viscous liquid or gel material, to a surface.

According to embodiments, and as shown in
The actuator 150 according to embodiments will now be described with reference to
Opposite the anchor 152 of the actuator 150 in the y-direction is the pressing pad 151 of the actuator 150. The pressing pad 151 of the actuator 150 is configured so that a finger, such as an index figure, or a thumb of a user can rest on the pressing pad 151 of the actuator 150. When pressure is applied to the pressing pad 151 of the actuator 150, such as by a user's finger or thumb, the actuator moves in the direction of arrow a into the cavity 400 of the device for dispensing a material 100. Accordingly, when a tube of material to be dispensed—such as a viscous liquid or gel, including an adhesive—is present in the cavity 400 of the device for dispensing a material 100, applying pressure to the pressing pad 151 of the actuator 150 causes the actuator to move in the direction of arrow a and into the tube of material to be dispensed, thus dispensing the material to be dispensed from the tube, as will be described in more detail below. A portion of the pressing pad 151 extends through the orifice 115 in the first surface 110 so that a user can easily access and apply pressure to the pressing pad 151.
The actuator 150 also comprises an arced portion 153 that extends from the anchor 152 to an arm 154 of the actuator 150. The arm 154 of the actuator, in turn, extends from the arced portion 153 to the pressing pad 151 of the actuator 150. This arced portion 153 of the actuator 150 allows the actuator 150 to fit into the cavity 400 of the device for dispensing a material 100. Further, the arced portion 153 of the actuator 150 provides the actuator 150 with an elastic effect such that when pressure is applied by a user to the pressing pad 151, the actuator moves in the direction of the arrow a into the cavity 400, but when the pressure is removed, the actuator 150 returns to its original position. Accordingly, the actuator is, in embodiments, made from materials that provide this elastic effect. In embodiments, the second surface 120 of the device for dispensing a material 100 is a rigid surface that allows the actuator to have this elastic effect. And, in some embodiments, the second surface 120 does not include any orifices.
The actuator 150 further comprises a planar contact surface 155 that is positioned opposite to a portion of the pressing pad 151. When a tube of material to be dispensed is present in the cavity 400 of the device for dispensing a material 100, the planar contact surface 155 of the actuator 150 is configured as the portion of the actuator that contacts a majority of the tube of material to be dispensed. The actuator also comprises an angled surface 156 adjacent to the planar contact surface 155 and positioned toward the first endface 130 of the device for dispensing a material 100 relative to the planar contact surface 155. Thus, an intersection 157 between the angled surface 156 and the planar surface 155 is present. In this way, the angled surface 156 of the actuator is positioned toward the shoulder of a tube of material to be dispensed relative to the planar contact surface 155 when such a tube of material to be dispensed is present in the cavity 400 of the device for dispensing a material 100.
An angle θ is present between the planar contact surface 155 and the angled surface 156. In embodiments, the angle θ is from 160° to 170°, such as from 161° to 170°, from 162° to 170°, from 163° to 170°, from 164° to 170°, from 165° to 170°, from 166° to 170°, from 167° to 170°, from 168° to 170°, or from 169° to 170°. In embodiments, the angle θ is from 160° to 169°, such as from 160° to 168°, from 160° to 167°, from 160° to 166°, from 160° to 165°, from 160° to 164°, from 160° to 163°, from 160° to 162°, or from 160° to 161°. In embodiments, the angle θ is from 161° to 169°, such as from 162° to 168°, from 163° to 167°, or from 164° to 166°. The angle θ is configured such that when a tube of material to be dispensed is present in the cavity 400 of the device for dispensing a material 100 and pressure is applied to the pressing pad 151 by a user such that the actuator 150 is fully depressed, the angled surface 156 provides room for a reservoir to be formed in the tube of material to be dispensed.
According to embodiments, a backstop 158 is positioned on the actuator 150 between the anchor 152 and the planar contact surface 155. The backstop 158 extends from the underside of arm 154 of the actuator 150 and extends in the same direction as the anchor 152 in the z-direction. According to embodiments, and as depicted in

With reference now to
Embodiments will be further clarified by the following example.
Tests were performed to compare the amounts and percentages of adhesive dispensed from tools made in accordance with the embodiments described above and illustrated in the accompanying drawings (identified in the Table as “Ex.”). The tools were assembled with metal tubes containing approximately 6 gm of cyanoacrylate liquid adhesive obtained from Adhesive Systems, Inc., Frankfort, Ill. For comparison, 10 Loctite® Precision Pen Super Glue dispensers, manufactured by Henkel Corporation were purchased at retail (identified in the Table as “Loctite®”). For the tests, adhesive was dispensed by squeezing with both hands until no more adhesive came out of the devices. The amounts of dispensed adhesive were then weighed. The total fill weight of each of the tubes was determined by removing the adhesive-containing tubes from the respective dispensing tools, further squeezing each tube by hand, followed by squeezing each tube with pliers, including tube neck deformation, to dispense any remaining adhesive. Those amounts were also measured and added to the previous dispensed amounts to arrive at values for total fill weights. The results are reported in Table 1 below.
As can be seen in Table 1 above, significantly more product was dispensed using a device for dispensing material according to embodiments disclosed and described herein
