Definitions

  • Packaging for consumer products has previously been provided in the form of tubes and has been used to contain various types of products, e.g., food products, hair care products, cosmetic products, and dentifrice compositions such as toothpastes, gels, or combinations containing part paste and part gel.
  • Such tubes are generally formed with a shoulder area at which the tube body narrows down to a nozzle having an orifice that can be resealably closed or capped.
  • This flavor loss effect tends to be particularly pronounced for the portion of the dentifrice that is contained in the shoulder area of the tube, which is also the portion that is first dispensed by the user. This is due to the fact that the flavor migration rate of the product in the shoulder area of the tube tends to be slower than that of its transmission rate though the shoulder material.
  • a loss or alteration of the original flavor characteristic can be perceived by many consumers, especially for product dispensed during the first few squeezes of the tube.
  • the consumer's perception of the product or the brand as a whole may be significantly and negatively influenced during the initial uses of the product, despite the fact that the original flavor characteristic of the remainder of the product is substantially unaffected.
  • the present invention is directed to a tube for containing and dispensing a contents, comprising: (a) a body portion; (b) a shoulder portion sealingly attached to the body portion, the shoulder portion and the body portion bounding a shoulder area in the interior of the tube, and the shoulder portion provided with at least one extension extending into the interior of the tube from the shoulder portion in the direction of the body portion; and (c) a nozzle sealingly attached to the shoulder portion and provided with an orifice through which the contents can be dispensed; wherein the contents contained in the shoulder area of the tube are substantially prevented from being dispensed when the tube is squeezed.
  • Figs. 3-7 show partial sectional views of additional preferred embodiments of the tube of the present invention
  • Fig. 8 is a graphical representation of the percentage of flavor additive present per dispensed gram of a dentifrice, showing conventional tube profiles and a profile for a preferred embodiment of the present invention.
  • the tube may be useful for containing and dispensing other products where it is desirable to prevent the portion of the product contained in the shoulder area from being dispensed, for example, food products, hair care products, cosmetic products, and the like.
  • the use of the term "dentifrice” herein should be understood to non-limitingly include oral care compositions such as toothpastes, gels, and combinations of such pastes and gels.
  • the tube body 12 may be comprised of any materials known to those of skill in the art that provide adequate storage of the dentifrice or other product contained in the tube.
  • the materials comprising the body 12 should have no reaction with the components that comprise the contents, such that the contents could be rendered unsafe or otherwise unsuitable for consumer use. They should, of course, also be durable enough to withstand normal consumer use without leakage, tearing or breakage, etc.
  • suitable materials from which the tube body 12 may be comprised include polyethylenes, such as low density polyethylene (“LDPE”), linear low density polyethylene (“LLDPE”), and high density polyethylene (“HDPE”), ethylene acrylic acid (“EAA”), foils, such as aluminum foil, or any of the above materials in any combination, for example, formed as a laminate structure.
  • polyethylenes such as low density polyethylene (“LDPE”), linear low density polyethylene (“LLDPE”), and high density polyethylene (“HDPE”), ethylene acrylic acid (“EAA”), foils, such as aluminum foil, or any of the above materials in any combination, for example, formed as a laminate structure.
  • LDPE low density polyethylene
  • LLDPE linear low density polyethylene
  • HDPE high density polyethylene
  • EAA ethylene acrylic acid
  • foils such as aluminum foil, or any of the above materials in any combination, for example, formed as a laminate structure.
  • the shoulder portion 14 is attached to the tube body 12 in continuous bonded or sealed contact such that the contents of the tube are prevented from leaking out at this juncture.
  • the nozzle 16 and the shoulder 14 are preferably continuously formed from a unitary piece of material (e.g., by injection molding) as shown in the Figures; alternatively, they may be comprised of separate pieces fused or otherwise securely attached to each other by any means known to those of skill in the art.
  • the nozzle 16 and the shoulder 14 preferably have the same material composition, but alternatively may be comprised of different material compositions.
  • suitable materials from which the shoulder portion 14 and the nozzle 16 may be comprised include the polyethylenes described above.
  • the shoulder portion 14 is further comprised of an inward extension 18.
  • the inward extension 18, the shoulder 14, and the nozzle 16 are all formed from a unitary piece of material (e.g., by injection molding) as shown in the Figures; alternatively, they may be comprised of separate pieces fused or otherwise securely attached to each other by any means known to those of skill in the art. In addition, they preferably have the same material composition, but alternatively may be comprised of differing material compositions.
  • At least one extension 18 is located in the interior of the tube 10, and extends from the shoulder portion 14 in the general direction of the body portion 12 (as opposed to extending in the general direction of the nozzle 16). This extension 18 may be provided in various configurations, as will be explained in greater detail below.
  • the extension 18 functions as a baffle or funnel that permits the portion of the contents contained in the central region C of the tube 10 (i.e., generally under the nozzle 16) to be dispensed, while substantially preventing the contents contained in the shoulder areas S (i.e., the interior region of the tube that is generally bounded by the body portion and the shoulder portion) from being dispensed, when the tube 10 is squeezed by the user. Without the extension 18, content contained in the shoulder areas S is free to mix into the dispensing flow. Thus, the extension 18 maintains a static layer of the contents in the shoulder areas S.
  • the extension 18 extends into the interior of the tube in a direction that is parallel to the nozzle 16 (and also parallel to the imaginary centerline 25 longitudinally drawn through the tube 10 from the center of the nozzle orifice).
  • the extensions 18 are not parallel to the nozzle 16.
  • the extensions 18 are provided at an angle ⁇ formed with respect to an imaginary line 27 drawn in the longitudinal direction of the tube 10 from the interior wall 16a of the nozzle 16.
  • the angle ⁇ may extend up to 60 degrees in either direction with respect to the imaginary line 27.
  • the embodiments represented by the previous examples have many advantages. For example, they can provide an improved product in which consumers can enjoy a pleasant, uniform flavor characteristic throughout the entire usage cycle of the product, from beginning to end. Lowered product cost is also possible, as there is no need to add more flavor to the dentifrice to compensate for the flavor loss in the product near the shoulder area. Elimination of the need for the barrier insert may reduce the overall packaging costs and is further believed to be environmentally-friendly. In addition, since some flavor additives escape very easily through insertless tubes, indicating that consumers may easily perceive a loss of original flavor characteristic, some dentifrice formulations cannot be placed in insertless tubes. However, all formulations may be provided in an equally advantageous manner when using the tubes according to the present invention.
