Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Field of Technology]

The present invention relates to an inner bag-type container provided with a dispensing pump with an improved immersion tube. More particularly, the present invention relates to an improved dip tube for a shrinkable bladder that substantially eliminates the outflow of air as the contents are dispensed.

[0002]

BACKGROUND OF THE INVENTION

Containers or bottles with a dispensing pump for dispensing the contents of the liquid contained in the container have been used for a long time and have been manufactured in various designs. One such container design, commonly referred to as an inner bag type container, is one that is manufactured by a co-extrusion blow molding process or has other structures. Have. The container generally includes a rigid or essentially rigid outer container structure and a plastically shrinkable, flexible bag contained within the outer container structure. The inner bag is filled with the contents, and the discharge pump is inserted into the inner bag. The inner bag also has a certain amount of headspace air,
For example, it is designed to respond to manufacturing requirements during filling, such as preventing overfilling or following prescribed criteria. The dispensing pump is mounted so as to seal the mouth of the outer container with, for example, a screw-type lid or a snap-type lid. Each time the pump head is pressed, a certain amount of content is pumped, the volume of the bladder shrinks and the filled content is discharged from the bladder under the effect of the pressure drop. For example, JP-A-4-3397
No. 59, JP-A-5-77345, JP-A-4-115114, JP-A-5-310265, JP-A-5-213372, JP-A-5-21
No. 3373, JP-A-6-18217, JP-A-6-27523,
And EP-A-0182094. This inner bag-type container is preferably used for filling and pouring out liquid or lotion type products such as shampoos, conditioners, hand soaps, body shampoos and cosmetic lotions, especially for products having a relatively high viscosity. Desirably used for delivery.

However, currently available inner bag-type containers have been found to have the drawback that when the pump head is pressed, the air contained in the inner bag (ie, headspace air) is pumped out with the product. . In some instances, when the pump head is pressed, no product is dispensed and only air is exhausted. Consumers usually expect the simultaneous dispense of air and content as they move to the end of the container use cycle, where most of the content is already dispensed. In a bag, it happens at an unexpected time during its use. This aeration phenomenon, commonly referred to as "sputtering", is negatively perceived by consumers purchasing such a packaged product, i.e., much of the product remains in the container If this is clear, it seems to be a rather inconvenient, carefree phenomenon. Alternatively, consumers consider the pump broken or otherwise defective.

[0004] Inner-bagless containers with dispensing pumps have also been provided previously. This type of container generally consists of a rigid or semi-rigid outer container structure directly filled with the contents to be poured out, without an inner bag. "Sputtering" in this type of container is much less, and it tends to occur only as the consumer normally expects to go to the end of the container use cycle where the remaining contents are low. However, containers without inner bags have several disadvantages. That is, it is difficult to completely discharge the same amount of contents as can be discharged by the inner bag type container; it is difficult to pour out a product having a relatively high viscosity compared to the inner bag type container; Since air holes must be provided in the pump structure of the bagless container, the contamination of the contents is more likely to occur than in the inner bag type container.

[0005] Therefore, there is provided an inner bag type container with a discharge pump, in which the contents contained in the container can be easily and uniformly discharged, and "sputtering" is substantially eliminated throughout most of the container use cycles. It is desired. No existing technology has all the advantages and benefits of the present invention.

[0006]

[Detailed description]

FIG. 1a shows a conventional inner bag type container 10. The container 10 comprises an outer container structure 12, which is usually rigid or essentially rigid, a plastically deformable and shrinkable inner bag 14 inside the outer structure 12, and a pump 16. External structure 12
Is desirably made of a molded thermoplastic resin such as polypropylene or polyethylene. Similarly, the inner bag 14 is desirably made of a molded thermoplastic resin such as PET (polyethylene terephthalate) or nylon. The inner bag 14 is arranged in a non-laminated manner inside the outer structure 12. Further, the inner bag 14 includes the outer structure 12.
Along one side from the neck to the bottom by an adhesive seam (not shown). The container may desirably be made by a co-extrusion blow molding process (see EP-A-0182094) or by other structures.

FIG. 1 a shows a portion of the outer structure 12 cut so that the inner bag 14 is visible. The inner bag 14 is a shrinkable bag filled with a liquid content 15 to be sent out. For example, content 15 may be a hair care product such as a shampoo, conditioner, hair treatment, or a liquid soap, body shampoo, or other cosmetic lotion, or any other lotion or liquid that one wishes to pour. Generally, inner bag type dispensing containers have a relatively high viscosity (eg, 10,000
(0 cps or more) This is particularly advantageous when used for the contents 15. The inner bag 14
It also contains a certain amount of headspace air 17.

The pump 16 generally includes a nozzle 16a, a lid 16b screwed to the neck of the external structure 12, a tank 16c, and a dip bar 16d. Also within the pump 16 are several components such as a spring, two sealing components, and a shaft. These internal components are not shown for ease of reference in the drawings. These internal components may then be selected and assembled in any manner known to those skilled in the art.

The tank 16 c and the immersion bar 16 d extend inside the inner bag 14. When the pump head 16e is pressed, the contents 15 are discharged. If it is desired to dispense some content, the user depresses the pump head 16e with a pressing force, as shown in FIG. 1a. This pressing force “P” generates a certain amount of suction in the inner bag 14. In general, every time the pump head 16e is pressed, a certain amount of the contents 15 is dispensed. For example, when the contents 15 are shampoo, usually about 3.2 ± 0.5 grams per press is appropriate. It is. For cosmetics, lower amounts are desirable.

In the conventional structure shown in FIG. 1 a, the suction part 18 is located at almost the middle height of the outer structure 12 of the container 10, in which the contents 15 are removed from the inner bag 14. The pump 16 moves upward toward the tank 16c (and finally is ejected from the container through the nozzle 16a by the pressing force P). As will be described in detail below, it is considered that the position of the suction portion 18 is a cause of sputtering in the conventional inner bag type container.

A partial perspective view of the dip bar 16d of the conventional inner bag type container 10 is shown in FIG. 1b. For example, JP-A-5-319467, JP-A-5-319468,
And JP-A-6-49353. From FIG. 1b, it can be seen that the immersion bar 16d is not provided with any internal space in which the contents can be lifted by the suction generated by the pressing force P. Instead, the immersion bar 16d is usually cross-shaped and provided with grooves, for example 20a-20d.

The grooves 20a to 20d provided in the immersion bar 16d are used to cause the contents 15 to effectively flow up the inside of the grooves 20a to 20d at the time when the volume of the inner bag 14 is contracted, and to enter the tank 16c. I am trying to enter. Since the inner bag 14 contracts when the contents 15 are poured out during use, the grooves 20a to 20d are provided to prevent the suction position from being closed.

A disadvantage of the design of the conventional container 10 shown in FIGS. 1 a and 1 b is that, after a certain amount of the contents 15 have been poured out of the container 10, the headspace in addition to the contents 15 The air 17 is sent out. Further, the contents 15 may not be sent out only by the upper space air 17. This aeration is commonly referred to as "sputtering." Thus, little or no dispensing of content 15 (i.e., the product that the consumer intends to dispens for use), even though it is clear that the container still contains significant content. It happens that there is nothing. Many consumers find the occurrence of such aeration or sputtering to be rather inconvenient and uncontrolled. In addition, there is a tendency to have a negative perception of the vessel that causes the sputtering, and furthermore, consider the pump to be defective or broken. This negative perception even affects consumers' future purchases.

In the conventional inner bag type container shown in FIGS. 1A and 1B, when the height of the contents 15 remaining in the container 10 becomes about the height of the suction portion 18, sputtering generally starts to occur. As the height of the contents 15 decreases, the volume of the inner bag 14 decreases, and the head space air 17 moves downward toward the suction site 18. Contents 1
As more 5 is dispensed, headspace air 17 continues to move downward toward the bottom 42 of the container. This downward movement of the headspace air 17 causes some headspace air 17 to be pumped out with the contents 15. Thus, sputtering continues to occur until all headspace air 17 has been exhausted. In fact, once sputtering has begun, it continues to occur for the remainder of the consumer's life with the container. See the graphs in FIGS. 6a-6c for this fact.

The pouring pump 30 of the present invention substantially eliminates the problem of sputtering. As shown in FIG. 2, the dip tube 34 is composed of two parts, a hollow portion 36 and an end portion 38, which extend from the tank 30c toward the bottom 42 of the container 40. The hollow portion 36 functions to delay the sputtering due to the downward movement of the head space air 17, and the tip portion 38 closes the suction position by the contraction of the inner bag 14 caused by the delivery of the contents 15. Work to prevent. As in the case of the conventional container, the tank 30c and the immersion tube 34 extend inside the inner bag 14.

The suction part 32 is located at the lowermost end 37 of the hollow part 36 of the immersion tube 34.
In other words, it is located not in the middle of the container 40 but in the bottom 42 of the container. Unlike the conventional dip bar 16d, the dip tube 34 of the present invention is hollow, and the contents are withdrawn through (i.e., inside) the dip tube, reach the tank 30c, and then are finalized via the nozzle 30a. Is discharged from the container 40.

[0021] Preferably, the suction site 32 is located corresponding to the level of the existing contents when no more than about half of the overflow volume of the container remains in the container. The term "overflow volume" is the sum of the volume of the filled contents, the volume of headspace air and the volume of the internal dispense pump. The overflow volume of this container design will vary based on the actual design factors (eg, size, shape, configuration) of the container. Thus, the exact position of the suction site relative to the bottom 42 of the container 40 will vary.

A preferred embodiment of the tip 38 and the hollow portion 36 of the dip tube 34 of the present invention is more clearly shown in FIG. The tip 38 is mounted in the lowermost end 37 of the immersion tube 34. Preferably, the distal end portion 38 is provided with grooves 39a to 39d. These grooves 39a-39d allow the tip 38 to smoothly flow into the immersion tube 34 by suction even if the inner bag 14 shrinks with each dispense of the content 15. Enable to work effectively to ensure.

Accordingly, when the dispensing pump 30 of the present invention is used in an inner bag type container, sputtering is substantially eliminated in most of the use cycles of the container. This means that when the pump head 30e is pushed, the headspace air 17 is at least until the height of the contents 15 of the container reaches at least the height of the suction position 32 at the lowermost end 37 of the hollow part 36 of the immersion tube 34. Due to the fact that it does not substantially enter the immersion tube 34 with the contents 15. Thus, the container 40 of the present invention exhibits a uniform pouring condition, at least up to the first occurrence of aeration or sputtering. In a preferred embodiment of the present invention, it is believed that the initial aeration or sputtering will not occur substantially until most (ie, at least 50% or more) of the contents have been pumped out by the consumer.

FIGS. 4 a and 4 b show bottom views of another preferred embodiment of the configuration relating to the tip 38 of the present invention. However, many other tip configurations are possible without losing the advantage of no sputtering and should be considered within the scope of the present invention.

FIGS. 5 a to 5 c show another preferred embodiment of the dip tube 34 in the present invention. In these embodiments, there is no separate tip 38. Instead, the lowermost end 37 of the dip tube 34 is itself cut out and contoured end.
) 35. This contour end 35 may be made by any suitable method such as cutting, molding, forming, shaping, stamping, or other means known to those skilled in the art. The contour end 35 may be configured as a square 35a, a wave 35b, a zigzag 35c, or the like. It will be appreciated that many other configurations of the profile end 35 are possible and are within the scope of the present invention.

Comparing the dispensing characteristics shown in FIGS. 6 and 7 is helpful in understanding the advantages of the present invention. 6a to 6c are graphs showing the state of change of each dispensing amount with respect to the number of times of dispensing for a typical conventional inner bag type container with a dispensing pump.
7a to 7c are graphs showing a state of a change of each amount to be dispensed with respect to the number of dispensations for a typical inner bag type container with a dispensing pump according to the present invention.

Referring to FIGS. 6 a-6 c, there is shown the variation in the dispensing amount of a hair conditioner placed in a 500 g conventional inner bag type container with a dispensing pump.
The x-axis represents the number of dispenses. More specifically, x = 1 corresponds to the first press of the pump head for the purpose of dispensing the contents, x = 25 corresponds to the 25 th press of the pump head, and so on. The y-axis represents the amount of content (in grams) that is actually pumped out each time the pump head is pressed. 5 including hair conditioner
For a 00 gram container, the target volume delivered each time the pump head is pressed is about 3.2 grams. The typical number of dispenses for such a 500 gram inner bag container is about 180.

For the container sample shown in FIG. 6 a, the first aeration or sputtering occurs at the time of the 99th dispense, ie, about the 99th press of the pump head. At that point, about 36.90% of the conditioner remains in the container.
For the container sample shown in FIG. 6b, the first aeration or sputtering occurs at the time of 74 pours, ie, about 74 times when the pump head is pressed. At that point, about 52.10% of the conditioner remains in the container.
For the sample of the container shown in FIG. 6c, the first aeration or sputtering occurs at the time of 67 pours, ie, about the 67th press of the pump head. At that point, about 56.92% of the conditioner remains in the container.

[0029] In contrast, Figures 7a-7c show a typical dispense volume for a preferred embodiment of a 500 gram bladder containing a hair conditioner with an improved dispense pump according to the present invention. The fluctuation is shown. From these figures it can be seen that unwanted sputtering has been substantially eliminated. At least until about the first occurrence of aeration or sputtering, the variation in the dispensed volume is substantially constant, and this occurs during a later use cycle than in the conventional bladder container shown in FIG. You can see that it is. It can be seen that initial aeration does not occur substantially until at least 50%, preferably more than 30% of the contents have been pumped out. More preferably, substantially no initial aeration occurs until the content in the container is about 10-15% or less.

For the container sample shown in FIG. 7 a, the first aeration or sputtering occurs at the time of 153 pours, ie, when the pump head is pushed 153 times. At that point, about 8.37% of the conditioner remains in the container.
For the container sample shown in FIG. 7b, the first aeration or sputtering occurs at the time of 152 dispenses, ie, about 152 times when the pump head is pressed. At that point, about 7.21% of the conditioner remains in the container. For the sample of the container shown in FIG. 7c, the first aeration or sputtering occurs at the time of 146 pours, or about 146 times, when the pump head is pressed. At that point, about 8.89% of the conditioner remains in the container.

As can be seen from FIGS. 6 and 7, even for containers of the same size and containing the same contents, the exact dispensing characteristics of the container will vary depending on the container being observed. This includes the actual design of the container, manufacturing tolerances, the cross-sectional area of the container body (constant or non-constant, etc.), the exact location of the suction site relative to the designated container design and height, and the material of the inner bag. This is due to factors. In addition, the product fluidity of the contents placed in the container is an important factor in the dispensing characteristics of the container.

For the distributions shown in FIGS. 6 and 7, the measured container is integrated with a uniform cross-sectional area from the shoulder to the bottom of the container, the contents have a viscosity of about 20,000 cps, The bag is made of nylon and the suction area of a conventional container (FIG. 6) is at about half the height of the container, while the suction area of the preferred embodiment of the present invention (FIG. 7).
Is at the lowermost end of the dip tube.

The dispensing characteristics of the conventional bladder container shown in FIGS. 6a-6c show that initial sputtering / aeration occurs when a large amount of product remains in the container. As indicated by the data at y = 0, the pump head may be continuously depressed to continuously pump out only air. In some instances, sputtering may continue until almost all of the headspace air is exhausted.

The example shown in FIG. 7 shows that the amount of product remaining at the time of the first aeration is much less than in the case of the conventional container shown in FIG. At least up to the point of the first aeration, the variation in the dispensed volume is substantially constant, indicating that there is no undesired sputtering on the whim.

8a to 8c show typical dispensing characteristics of a conventional bladderless container with a conventional dispensing pump. This type of container differs from the inner bag type container in that the entire structure includes a semi-rigid outer structure that is directly filled with contents, ie, there is no inner bag. A conventional container of this type uses a dispensing pump with a hollow immersion tube. However, the overall structure of this container is distinctly different from the overall structure of the inner bag type container and does not have the particular advantages that the inner bag type container has.

For example, a container without an inner bag must be provided with an air hole in the structure of the dispensing pump so that the outer structure does not contract when the contents are delivered. Through this vent, water or other contaminants enter the interior of the container. Even in the inner bag type container, the air hole is useful to prevent the outer structure from shrinking, but it is generally provided not as a part of the pump structure but as a small gap in the bottom 42 of the outer structure. Can be There is no need to provide any air holes in the dispensing pump of the inner bag, and the risk of contamination is substantially eliminated.

As compared with the inner bag type container, the conventional container without inner bag depends on the viscosity of the contents,
Initial aeration or sputtering occurs when about 10-15% of the contents remain in the vessel. It is difficult, if not impossible, to discharge the rest of the contents after the first aeration has occurred. In the case of an inner bag type container, it is possible to easily discharge up to about 3% of the contents.

A further advantage of the inner bag type container compared to the inner bagless container is that higher viscosity products can be easily discharged. For example, an inner bag-type container can discharge up to about 95% of the contents having a viscosity of 20,000 cps, while a container without an inner bag can discharge only about 70% of the contents.

The foregoing characteristics of the bladderless bottle are graphically illustrated in FIG. For the sample of the container shown in FIG. 8a, the first aeration or sputtering was 126
Wakes up when the pump head is pressed at the time of dispensing, ie, about 126 times. At that point, about 12.69% of the conditioner remains in the container. For the sample of the container shown in FIG. 8b, the initial aeration or sputtering was 130
Wakes up at the time of the first dispense, about 130 times when the pump head is pressed. At that point, about 13.73% of the conditioner remains in the container. For the sample of the container shown in FIG. 8c, the initial aeration or sputtering was 12
It occurs at the time of 7 dispenses, ie, about 127 times when the pump head is pressed.
At that point, about 14.18% of the conditioner remains in the container.

Based on the foregoing, it can be seen that the preferred embodiments of the present invention are more advantageous than conventional bladder container designs and conventional bladderless container designs. This preferred embodiment provides for easy evacuation of the product, especially of the viscous product, while substantially eliminating the problem of whimsical sputtering, at least up to the point of initial aeration.

Another advantage of the preferred embodiment of the present invention is that if the user twists open the lid of the pump from the outer structure of the container (this allows air to enter the bladder and the headspace air volume inside the bladder) Increases). In a conventional inner bag type container, once the user twists the lid and reseals the pump to the container, the pump head must be depressed many times to resume the product outflow. In a preferred embodiment of the present invention, even if the lid is removed and the air further enters the inner bag, product spill resumes quickly.

Examples The following examples further describe and demonstrate embodiments within the technical scope of the present invention. This example is provided for illustrative purposes only, and should not be construed as limiting the invention, and many modifications of the invention may be made without departing from the spirit and scope of the invention. is there.

The measurements mentioned here have been performed at 25 ° C. Sample No. Number of times of dispensing (X) Remaining amount of product when the first sputtering occurs (%) 1 145 9.69 2 138 9.98 3 153 8.37 4 152 9.49 5 152 7.22 6 145 7. 71 7 141 9.62 8 146 8.89 9 143 9.52 10 147 8.98

From the foregoing examples, it can be seen that sputtering does not take place until at least 50%, and preferably more than 50%, of the product has been pumped out of the container, and that the initial sputtering reduces the amount of content remaining in the container. It can be seen that it is awake when relatively few.

The embodiments disclosed and shown by the foregoing examples illustrate the previously known problem of spontaneous sputtering even when large amounts of content remain in the inner bag.
