Definitions

  • the present invention relates to a shoulder design for tubes. More specifically, the present invention relates to a shoulder design for tubes wherein the dispensed amount of the product contained in the shoulder area of the tube is minimized, and is particularly useful for tubes containing dentifrice compositions such as toothpastes.
  • 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.
  • the product In standard tubes, the product is generally dispensed in a "plug flow" manner, i.e., the product located immediately below the nozzle is dispensed first, with the rest of the product gradually becoming mixed into the dispensing flow as the tube is squeezed during subsequent uses.
  • tubes formed from laminates comprising plastics such as polyethylenes, and sometimes additionally containing a foil or acetate layer have previously been provided.
  • the dentifrice products contained therein typically include flavor additives for enhancing consumer acceptance of the product, in addition to the effective ingredients that promote oral health.
  • the dentifrice contained in such laminate tubes may lose some of this flavor due to absorption and transmission losses into the packaging materials that comprise the tube.
  • 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.

  • 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 of the present invention is desirably provided with a cap to protect the contents from exposure to the atmosphere when the tube is not in use.
  • Any type of cap or lid that is resealably fitted to the tube nozzle may be used with the tube of the present invention, for example, a screw-on type cap.
  • the cap may further be provided with a flip-open top for more convenient consumer use.
  • the cap is not shown in the accompanying Figures.
  • Fig. 1 a partial cross sectional view of a preferred embodiment of the tube of the present invention is shown.
  • the tube 10 is generally comprised of a tube body portion 12, a shoulder portion 14, and a nozzle 16.
  • the nozzle 16 is provided with an orifice 20 through which the product is dispensed when the tube body 12 is squeezed by the user.
  • the nozzle 16 may be provided with threads 22 in order to facilitate the fitting of a cap (not shown) to the nozzle 16.
  • 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.

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 overall flavor characteristic of the product tends to be diminished as a result of the absorption and transmission of the flavor additive into the packaging materials such as the tube laminate, the shoulder, and the barrier insert.
  • some flavor additives are comprised of several different components, and in such cases, there may be uneven rates of migration between these various components to the tube packaging materials. This causes a loss of the original flavor characteristic.

  • the consumer's first impression of the dentifrice product as a whole may be a negative one. This is especially undesirable since the initial uses of the product form a consumer's "first impression", and a negative first impression tends to adversely effect a consumer's opinion of the total product and of the overall brand.
  • the lack of or alteration of flavor at initial use is particularly noticeable in smaller tube sizes, e.g., 10g, 20g, 40g, and may be intensified during storage time before purchase and use. For the foregoing reasons, it is highly desirable to prevent the dentifrice contained in the shoulder area from being dispensed.
  • the design of the tube 10 of the present invention can substantially prevent the flow of the dentifrice contained in the shoulder area from dispensing out or mixing with the rest of the product.
  • the extension 18 creates a static layer of dentifrice in the shoulder area S that is not dispensed as the tube 10 is squeezed.
  • This static layer is comprised of the dentifrice that has experienced a loss and/or alteration of the original flavor characteristic due to migration and transmission of the flavor additive.
  • the tubes 10 of the present invention provide a truer and more uniform flavor characteristic to the user throughout the entire usage cycle of the tube 10.
  • a conventional tube without an extension 18 is filled with colored gel G in the shoulder area, and with white paste W in the remainder of the tube.
  • the colored gel G represents that portion of the dentifrice that has a noticeable flavor loss or alteration of flavor characteristic, which is desired to be maintained within the tube (i.e., not dispensed).

  • a tube filled in such a manner is represented in Fig. 2a.
  • Fig. 3 shows a preferred embodiment in which the extension 18 is of a tapered shape to provide it with a degree of flexibility.

  • This barrier insert is typically a pre-molded piece that is placed on a heading tool before the tube body portion itself is put in position.
  • the barrier insert is often made of polybutylene terphthalate, which can withstand the injection pressures and temperatures of the heading plastic, and does not crack in the head.
  • the head plastic portion of the tube which is generally made of HDPE, locks the barrier insert in position as it is bonded to the remainder of the tube body portion.
  • this costly barrier insert can be eliminated.
  • the barrier insert is intended to help lessen the effects of the flavor inconsistencies by lessening the transmission of the flavor through the tube walls; however, the barrier insert itself still tends to absorb the flavor. Thus, it is not truly effective for preventing flavor inconsistency or alteration.
  • the preferred embodiments of the present invention are believed to better serve the purpose of preventing flavor inconsistency or alteration, thereby eliminating the need for the barrier insert.
  • the following example represents a 20 gram size dentifrice tube.
  • the percentage of flavor additive present at a given number of grams dispensed after the indicated period of storage time at the indicated temperature is measured for tubes of three constructions: (1) “With Extension” refers to a tube constructed according to the present invention; (2) “With Insert” refers to a conventional tube provided with a barrier insert; and (3) “Without Insert” refers to a conventional tube in which the barrier insert has been removed but which is not provided with an extension according to the present invention.

  • accelerated condition refers to storage of a sample for specified number of months at 40°C. Such a condition is believed to be representative of a certain shelf life period at ambient conditions. For example, “1.5 months, accelerated condition” is believed to be representative of a 1 year shelf life; and “4.5 months, accelerated condition” is believed to be representative of a 3 year shelf life.
  • the tube 10 of the present invention permits greater retention of the flavor additive than either of the other two conventional tube designs.
  • tube sizes such as 20g tubes are believed to represent the most severe case of flavor transmission and consequent flavor loss or alteration
  • larger tube sizes e.g., 40g or 120g
  • the tube diameter is typically the same for a 20g dentifrice tube and a 40g dentifrice tube, and the diameter of a 120g dentifrice tube is typically only slightly larger than that of a 20g tube.
  • the respective lengths of these tube sizes differ.
  • the diameter in the shoulder area is believed to be the most relevant dimension in determining the amount of dentifrice product that experiences the flavor loss or alteration.
  • 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.
