Description

  The present invention is directed to a bottle configured to contain a liquid dishwashing agent.

  Liquid dishwashing agents (for manually washing dishes) are well known with bottles containing them. However, there is a continuing need to provide a cost-effective quality experience to users, especially consumers who identify taste.

  The present invention is based on the surprising discovery that bottle “pushability” is a key quality parameter for a particular consumer segment in the dishwashing product category. The present invention maintains the same bottle preform (including the same amount of plastic) while providing a more concentrated form of the liquid dishwashing product overall size. Based on research to make it smaller. A consumer survey that assesses the potential negative impact of providing a more plastic bottle, when the consumer administers a detergent from the bottle as an increase in quality experience for all products (especially It was surprisingly observed to interpret the resulting larger “pushing force” (due to thicker bottle wall thickness or smaller bottle radius compared to the marketed product). The survey further suggests that the consumer uses his thumb to press the bottle while using the other finger for control. The search provides a number of potential advantages to the inventor described herein.

  One advantage of the present invention is having bottles that are low in liquid dishwashing agent (eg, compared to existing 250 ml implementations), especially when providing a concentrated form of the cleaning agent.

  Another advantage of the present invention is to have a bottle that provides the above identified features configured to contain about 200 ml of liquid dishwashing agent.

  Yet another advantage of the present invention is that it has a relatively large area in the body of the bottle that provides the desired pushability range (to suit different user hand sizes and dispensing styles). .

  Yet another advantage of the present invention is that it has the features identified above in a liquid dishwashing product that minimizes the use of thickener / structure agents and other rheology modifiers.

  Yet another advantage of the present invention is to provide a dishwashing product that is less messy when the user releases to press the bottle (eg, a detergent that spills from a dispensing cap, etc.) There is a faster and / or more forced vacuum created in the bottle to return the undispensed cleaning composition.

  Yet another advantage of the present invention is to provide a dishwashing product that has a user preferred administration experience.

  Based on this discovery, one aspect of the present invention provides a liquid dishwashing product comprising a plastic container comprising 150 ml to 225 ml of liquid dishwashing composition, said container comprising a bottle having an opening. An enclosure is attached to the bottle and in fluid communication with the opening, the enclosure including a resealable opening that, when opened, passes the included dishwashing composition therethrough. The plastic container has a longitudinal axis, the bottle and the enclosure have radial symmetry about the longitudinal axis, respectively, and the bottle is 41 mm to 61 mm, preferably 46 mm to Having a maximum diameter of 58 mm, the bottle has a lower base portion, a body portion, an upper neck portion, the body portion interposed between the base portion and the neck portion; The bottle portion defines the opening that the enclosure surrounds, and the height of the bottle is the longest dimension measured from the base portion to the opening (without the enclosure) along the longitudinal axis, and the bottle wall is It has a minimum thickness of 0.2 mm to 0.5 mm, preferably 0.3 mm to 0.4 mm, measured perpendicular to the longitudinal axis at the surrounding mid quarter section of the body portion.

  Another aspect of the present invention provides a plastic bottle configured to contain 190 ml to 225 ml of a liquid dishwashing composition, the bottle having a longitudinal axis and having radial symmetry about the longitudinal axis. And the bottle has a maximum diameter of 41 mm to 61 mm, preferably 46 mm to 58 mm, the bottle has a lower base portion, a body portion and an upper neck portion, the body portion comprising a base portion and a neck portion. Interposed between, the neck portion defines an opening defining an opening relative to the interior of the bottle, and the bottle height is the longest dimension measured from the base portion to the opening along the longitudinal axis, 135 mm 165 mm, preferably 140 mm to 160 mm, and the bottle wall measured 0.3 mm to 0.4 mm, preferably perpendicular to the longitudinal axis, in the mid-quarter section around the body part Having a minimum thickness of 0.32mm~0.38mm.

Consumer panel data that correlates thumb pressing force with consumer rating of ease of administering dishwashing products.

  The bottles of the present invention are made of plastic, preferably thermoplastic, more preferably a polyolefin such as polyethylene terephthalate (PET). Plastics may include recycled materials and / or biological materials. Preferably, the plastic is transparent or translucent so that the user can see the contents of the bottle. Of course, opaque bottles may also be used. Branding and other information can be provided by labels or shrink sleeves, or other known methods. The bottle is made from molding the thermoplastic into the desired shape. In one embodiment, the preform is molded from plastic and then the preform is stretch blow molded into the final bottle. In still other embodiments, the preform has a mass of 18 g to 25 g, preferably 19 g to 25 g, more preferably 20 g to 24 g, and more preferably 21 g to 23 g, or about 22 g, or a combination thereof. In still other embodiments, the bottle is approximately the same mass as the preform without content and enclosure, i.e., 18g-25g, preferably 19g-25g, more preferably 20g-24g, and even more preferably 21g- 23g, or about 22g, or a combination thereof.

  FIG. 1 is a perspective view of one embodiment of the dishwashing product (1) of the present invention. FIG. 2 is a front view of the bottle (3) of the dishwashing product (1) of FIG. Reference is made to both FIGS. The dishwashing product (1) comprises a plastic container (2) containing 150 ml to 225 ml of liquid dishwashing composition (not shown). Alternatively, container (2) comprises 175 ml to 200 ml, alternatively 190 ml to 210 ml, or 150 ml to less than 200 ml, or more than 200 ml to 225 ml, or about 200 ml, or a combination thereof. Liquid dishwashing compositions are described, for example, in US Patent Specification 2013/0029895 A1 (issued January 31, 2013). The liquid dishwashing composition may have a viscosity of 100 centipoise (cps) to 1,500 cps, alternatively 400 cps to 600 cps, alternatively 900 cps to 1,100 cps, or combinations thereof. Viscosity was measured using a BROOKFIELD viscometer, Model LV No., with a spindle rotating at 12 rpm. Measure with one spindle and measure at ambient temperature (eg 24 ° C.).

  1 and 2, the container (2) includes a bottle (3), and the bottle (3) includes a neck portion (17) defining an opening (4). The enclosure (5) is attached to the bottle and is in fluid communication with the opening (4) and closes the opening (4). The opening (4) opens into the bottle (3) (not shown). Thus, the enclosure (5) is also in fluid communication with any contents contained within the bottle (3). The opening (4) may have an inner diameter of 20-30 mm, preferably 22 mm-28 mm, or about 26 mm. One way in which the enclosure (5) is attached to the neck portion (17) is by corresponding threading (39). The threading (39) may be on the outer surface of the neck portion (17) and the corresponding threading may be seen on the inner surface of the enclosure (5) (not shown). The enclosure (5) is simply rotated and threaded on the neck portion (17) until a fluid tight seal is created. The enclosure (5) is also included when opened by the consumer (and pushed by weight when force is applied to the container, ie when the user's hand and / or product is generally inverted) Including a resealable opening (7) configured to dispense a dishwashing composition. One non-limiting example of the enclosure (5) is a “push-pull” cap. The diameter of the cap can affect the indentation force required to dispense the included liquid detergent composition. In one embodiment, the diameter of the opening (7) is 1.5 to 3.0 mm, preferably 2.0 mm to 2.4 mm, more preferably 2.1 to 2.3 mm, or about 2 mm, or 2 .2 mm. Another example of an enclosure is a “flip top” cap. Directly under the enclosure (5) (when the enclosure (5) is attached to the bottle (3)) the neck portion (17) is further (preferably perpendicular to the longitudinal axis (10) discussed below). There may be a neck ring (33) projecting radially around the outer surface of (17).

  1 and 2, the container (2) has a longitudinal axis (10), and the bottle (3), preferably the enclosure (5), is radially symmetrical about the longitudinal axis (10), respectively. Have sex. One advantage of radial symmetry is to provide the user with a uniform, potentially 360 degree constant bottle push experience. This is a bottle with bilateral symmetry (or other type of symmetry) that may be user dependent, holding the bottle in a specific or narrower defined area to have the best indentation experience Is symmetrical.

  The bottle (3) has a lower base part (12), a body part (15) and a neck part (17). The body portion (15) is inserted between the base portion (12) and the neck portion (17), the neck portion (17) defining an opening (4) in which the enclosure (5) closes. The base portion (12) contacts the table top or storage shelf when the liquid dishwashing product (1) is in the “standing position” (ie, non-inverted position). The bottle (3) height is the longest dimension measured from the base portion (12) to the opening (4) (without the enclosure (5)) along the longitudinal axis (10). In one embodiment, the height of the bottle (3) is 135 mm to 165 mm, preferably 140 mm to 160 mm, more preferably 145 mm to 155 mm, alternatively 147 mm to 157 mm, alternatively about 153 mm, or a combination thereof.

  The peripheral vertical midpoint (43) is located at half the height of the bottle (3). The midpoint (43) is around the bottle perpendicular to the vertical axis (10). The perimeter mid-quarter section (20) of the bottle is the area that is the central quarter around the bottle (3). The bottom plane (53) perpendicular to the longitudinal axis (10), at a quarter of the bottle height from the base portion (12), defines the bottom boundary of the surrounding mid-quarter section (20). At three-quarters of the bottle height from the base (12), the upper plane (51) orthogonal to the longitudinal axis (10) defines the upper boundary of the surrounding mid-quarter section (20). The surrounding longitudinal midpoint (43) divides the middle of the surrounding mid-quarter section (20).

  The wall (not shown) of the bottle (3) in the mid-quarter section (20) around the bottle (3) is 0.2 mm to 0.5 mm, preferably 0.3 mm to 0.4 mm, more preferably 0. A minimum thickness of .32 mm to 0.38 mm, alternatively 0.33 mm to 0.37 mm, alternatively about 0.35 mm, or a combination thereof. In one embodiment, the wall of the bottle (3) at the peripheral mid-quarter section (20) of the bottle (3) has an average wall thickness of 0.35 mm to 0.65 mm and the peripheral mid-quarter section (20 ) Wall thickness is measured perpendicular to the vertical axis (10).

  Various diameters or radial dimensions are measured perpendicular to the longitudinal axis (10). The diameter or radius of the bottle (3) can affect the indentation force for dispensing the cleaning composition from the container (2). In one embodiment of the invention, the maximum diameter of the bottle (3) is 41 mm to 61 mm, preferably 46 mm to 56 mm, more preferably 47 mm to 55 mm, alternatively 48 mm to 54 mm, alternatively about 51 mm, or a combination thereof. In one embodiment, the bottle (3) is the body portion (15) of the bottle (3), 32 mm to 52 mm, preferably 37 mm to 47 mm, more preferably 39 mm to 45 mm, or about 42 mm, or a combination thereof. Has the smallest diameter.

Consumer Testing 30 consumers in Kobe, Japan, have two experimental products and one OY (registered trademark) brand product marketed in Japan by the applicant (ie, The Procter & Gamble Company) ( The “thumb indentation force” was evaluated with respect to the desired indentation convenience (FIG. 6) and ease of administration rating (FIG. 7) from three dishwashing products, including 250 ml). The experimental product included bottles as described above, one with a 500 centipoise (cps) detergent composition and the second with a 1,000 cps detergent composition. Figures 6 and 7 summarize these findings.

  FIG. 6 details the results from a Japanese consumer panelist who generally prefers a thumb pushing force of about 20 Newton (N) for these hand dishwashing products. In a setting simulating dishwashing in a kitchen sink, the consumer would distribute the detergent composition from the dishwasher product onto the sponge, as would be done at home, for each of the three products. Directives are provided to panelists. For each dispense, the dishwashing product is fingerprinted where the consumer holds and dispenses. From the position of the thumb, the product is assessed for its thumb pushing force (N) using the apparatus of FIGS. 3-5 (described in more detail below), and a consumer rating for ease of pushing the product and Correlate. In FIG. 6, the X-axis represents the consumer rating, while the Y-axis represents the thumb push force of the assessed product. Due to consumer ratings, panelists were asked about their preference for “indentation ease” of dishwashing products, where a value of “0” is just right (ie, most consumer preferred), and −2 is firm. Too much (ie, thumb pressing force is too high), +2 is too soft (ie, thumb pressing force is too low). The average value of all 30 consumers testing three products is plotted in the graph of FIG. As suggested in FIG. 6, the most preferred consumer rating (ie, “0”) corresponds to a thumb pushing force of about 20 Newtons.

  FIG. 7 summarizes the findings of 30 consumer panelists that have been heard regarding the preferred “ease of administration” for thumb pushing force. The results suggest that the rating desired by the largest consumer of “100” also corresponds to a thumb push force of 20 Newtons. As in the previous study, in a setting simulating dishwashing in a kitchen sink, the consumption of the detergent composition was distributed on the sponge as performed at home for each of the three products. Directives are provided to the person. For each dispense, the dishwashing product is fingerprinted where the consumer grasps and dispenses. From the position of the thumb, the product is assessed for its thumb pushing force (N) using the apparatus described in FIGS. In FIG. 7, the X-axis represents the consumer rating (0-100), where 0 is the lowest consumer preference and 100 is the best consumer preference. The Y-axis represents the thumb pushing force (measured with thumb fingerprint) of the assessed product and correlates to the respective consumer rating. The average value of all 30 consumers testing three products is plotted in the graph of FIG. As illustrated in FIG. 7, the most preferred consumer rating (ie, “100”) corresponds to a thumb pushing force of about 20 Newtons.

  Looking at the consumer panelist data, a dishwashing product having a thumb depression of about 20N provides the most preferred “easy to push” and “easy to administer”.

Average Thumb Pressing Force It is an object of the present invention to provide a dishwashing product that provides a thumb pressing force of about 20 N based on the consumer panelist data described. However, based on unpublished research, it has been discovered that many variables can contribute to thumb pushing force. These variables may include bottle thickness, bottle radius, total bottle dimensions (eg capacity, length, etc.), potentially the viscosity of the liquid contained in the bottle, the enclosure opening, Also included is the position of the user's thumb or hand.

  One aspect of the present invention is measured at the outer surface of the bottle at the peripheral longitudinal midpoint (43), with the bottle free of contents and enclosure (to provide more accurate test conditions), 15 Newton (N) to 22N, preferably 17N to 22N, more preferably 18N to 22N, more preferably 19N to 21N, or about 20N, or a combination of thumb pushing force or average thumb pushing force (“ATSF”) A bottle of dishwashing product, which is described in more detail below. Without being bound by logic, it is believed that bottle structure and shape are significant factors that guide the user's thumb pushing force experience. In a preferred embodiment, the average thumb pushing force or ATSF is measured in the perimeter mid-quarter section (20) (as defined below) of the bottle.

  The ATSF is assessed with respect to the surrounding longitudinal midpoint and the surrounding mid-quarter section according to the method described herein. An empty bottle, containing no content and enclosure, is tested on a tensile tester. Test conditions are performed at 25 ° C. and about 60 percent relative humidity. Empty bottles are allowed to equilibrate to these conditions for at least 24 hours before conducting the test. A preferred brand and model number for the tensile tester is Lloyd Tensile Tester. Without being bound by theory, assessing empty bottles provides more accurate results (by reducing variables) and is generally the best predictor of consumer ATSF experience.

  With reference to FIGS. 1 and 2, the peripheral mid-quarter section (20) of the bottle (3) is designated based on the dimensions of the bottle (3). The ATSF is assessed at 4 perimeter equidistant locations for a total of 4 assessments on the perimeter longitudinal midpoint of the bottle (43) and a total of 12 assessments on the perimeter mid-quarter section (20) of the bottle (3). For example, if the tested initial position of the bottle (3) is 0 degrees, the bottle is rotated 90 degrees (about the vertical axis (10)) for the second measurement. The third assessment is rotated an additional 90 degrees (ie 180 degrees from the first assessment). Finally, the final fourth assessment is again rotated 90 degrees (ie, 270 degrees from the first assessment). These four assessments are then averaged to obtain the ATSF at the surrounding longitudinal midpoint (43). The average for a total of 12 assessments was taken against the ATSF assessed on the perimeter mid-quarter compartment (20) of bottle (3). Peripheral vertical midpoint data is taken as described above, but four peripheral equidistant positions are taken along the upper plane (51) and the other four peripheral equidistant positions are taken on the lower plane (53). Take along (total 12 assessments). As discussed above, the upper plane (51) and the lower plane (53) delimit at either end of the perimeter mid-quarter section (20) of the bottle (3). The height of the bottle (3) is measured along the vertical axis without the enclosure (5) secured to the bottle (3). One advantage of having a mid-quarter section around the bottle with the described ATSF is that it has a relatively large area of the bottle with a defined ATSF, which allows the user to grasp and press the bottle. In a potential area, it provides the user with the desired experience and accommodates the user's various hand sizes and potential indentation styles. The radial symmetry of the bottle (3) further supplements this advantage.

  Turning to FIGS. 3a, 3b and 3c, the bottle (3) is placed on the jig (25) to assess its thumb pushing force or its ATSF. The jig (25) has a base holding end (27) and an opposite neck holding end (29). The jig (25) is configured to receive the bottle (3) such that the longitudinal axis (10) of the bottle (3) is parallel to the level laboratory bench top (not shown). The base holding end (27) is concave and is designed to receive the outer surface of the bottle (3) closest to the base (12) of the bottle. The concave surface of the base holding end (27) generally resembles the radius of the peripheral outer surface of the bottle (3) (closest to the base (12)). For example, this may be approximately 1 / 10π radius to 1 / 3π radius (centered on the vertical axis (10)) to prevent the bottle from rotating during the test. Similarly, the neck holding end (29) is also concave so as to receive the outer surface of the bottle (3) of the neck portion (17) of the bottle (3) adjacent to the opening (4) of the bottle (3). Designed. The outer thread (39) is preferably in contact with the neck holding end (29). The concave surface of the neck holding end (29) generally resembles the outer surface radius of the neck portion (17). For example, this may be about 1π radius (about the longitudinal axis (10)) to prevent the bottle (2) from rotating during the test.

  FIG. 4 is an illustration of a loading probe (30) having a 10 mm diameter. The apex of the conical end (31) of the loading probe (30) contacts the perimeter mid-quarter section (or perimeter longitudinal midpoint) of the bottle (3). The conical end (31) is opposite the portion of the loading probe (30) that is operatively connected to a tensile tester (not shown). The loading probe (30) is typically perpendicular to the level bench top.

  FIG. 5 is an illustration of a loading probe (30) received in a rig (25) while connected to a tensile tester (not shown) assessing the ATSF (Newton) of an empty bottle (3). It is. The speed of the loading probe (30) is programmed at 12 mm / min with 3 mm displacement. Record the maximum load at 3 mm displacement.
