Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a squeeze-deformable external container, and the internal container that can be freely reduced in volume is detachably laminated so that the contents can be repeatedly dispensed without sucking outside air. Related to the dispensing container.
[0002]
[Prior art]
Japanese Utility Model Laid-Open No. 57-44063 and Japanese Utility Model Laid-Open No. 7-22951 have a description of the prior art regarding a squeeze-type dispensing container comprising an internal container and an external container containing the internal container.
[0003]
In the prior art described in Japanese Utility Model Publication No. 57-44063, a vent hole is provided in the bottom of the container body, and after the contents are poured out by squeeze of the container body, the space between the outer container and the inner container is removed. External air is introduced, the inner container retains its deformed shape, and the container body is restored to its original shape by its restoring force.
[0004]
In the prior art described in Japanese Utility Model Publication No. 7-22951, the outer container and the inner container are coupled and fixed, and the passage of the contents from the inner container is allowed, but the entry of the outside air into the contents is prevented. There is a second check valve that allows outside air to pass between the check valve, the external container, and the internal container, but prevents the outside air from entering between the external container and the internal container. It has a configuration.
[0005]
In addition, by providing a pair of vertical belt-like adhesive bands that adhere and fix the external container and the internal container over the entire height range of the container body, the internal volume can be reduced in volume without causing a reduction in the height direction. A method of restricting the form and thereby ensuring a flow path for the contents and smoothing the pouring operation is also generally used, and a pair of adhesive bands are arranged at positions that are axially symmetric with respect to the central axis of the body part. The method is simple and effective.
[0006]
[Problems to be solved by the invention]
However, in order for the adhesive band to exhibit its function, an adhesive band having a certain width is required. However, the portion where the adhesive band is formed becomes thick, and the body of the external container is a squeeze container. The adhesive band is shaped like a bone to prevent the uniform squeeze deformation, and the user feels uncomfortable in the hand feeling. There are problems such as that the adhesive resin forming the adhesive band is expensive.
[0007]
Usually, the outer surface of the body of the container is an important part of the appearance of the product by displaying the product name or decorating it by labeling, printing, etc. There were irregularities on the outer surface, there were problems in terms of process and appearance, and there was also a problem in appearance that the bone-shaped adhesive band itself was conspicuous.
[0008]
Therefore, the present invention was devised to solve the above-mentioned problems in the prior art, and the formation of an adhesive band that can be uniformly squeezed and has a small effect on the external appearance is a technical problem. An object of the present invention is to provide a squeeze-type dispensing container that can be smoothly achieved to the end, has a low cost, and has an excellent appearance.
[0009]
[Means for Solving the Problems]
Among the means of the present invention for solving the above technical problem, the means of the invention described in claim 1 includes an outer layer that forms a squeeze-deformable and recoverable flexible outer container laminated in a peelable manner. , Having a Delami bottle type container body formed by blow molding from an inner layer that contains the contents therein and forms an internal volume that can be freely reduced and deformed by reducing the internal pressure;
Having a pouring cap body assembled and fixed to the mouth of the container body;
Provided with a pair of vertical band-shaped regulation bands formed by a pair of vertical thin band-shaped adhesive bands in which the outer layer and the inner layer are bonded over substantially the entire height range of the container body substantially symmetrically about the central axis of the outer container. thing,
Providing the dispensing cap body with a first check valve portion that prevents backflow of contents into the internal container and entry of external air;
The external container is provided with an intake portion for introducing external air between the outer layer and the inner layer, and a second check valve portion is provided to open and close the intake portion so that air cannot be discharged from the intake portion. ,
It is in.
[0010]
In the first aspect of the invention, after the contents are poured out by the squeeze of the container body, when the squeeze is stopped and the pressing is released, the external container starts to be restored to its original shape by an elastic recovery force. The function of the first check valve provided on the dispensing cap body stops the dispensing of the contents, the backflow of the contents and the inflow of outside air to the internal container are stopped, and the internal container is reduced in volume and deformed. Therefore, external air is introduced between the outer layer and the inner layer from the intake portion, and the outer container is restored to its original shape.
[0011]
When the external container is squeezed again from its original shape, the air between the layers is sealed by the second check valve, so this air is pressurized and pressure is applied to the internal container. Things are poured out.
[0012]
Because the first check valve portion does not allow the outside air to flow into the internal container, there is no air pool in the internal container, and therefore the contents are always located facing the opening. Regardless of the posture of the dispensing container, the contents can be easily and quickly poured out, and problems such as decomposition of the contents and oxidative deterioration due to air can be prevented.
[0013]
The vertical band-shaped regulation band is formed from an adhesive band located at both end portions and a portion sandwiched between the adhesive bands and where the outer layer and the inner layer are not bonded (hereinafter referred to as a non-bonded portion). The effect of regulating the volume-reducing deformation of the inner layer is exerted in the entire width including the adhesive bands of the portion and both end portions.
[0014]
When this regulation band is formed over a substantially entire height range of the container body and a pair is formed substantially symmetrically with respect to the central axis of the outer container, free volume reduction deformation of the inner container is restricted, and As seen, the contents of the squeeze operation are poured out while the center part of a pair of unbonded inner layer parts (hereinafter referred to as inner layer deformed parts) located on both sides of this restricted zone is deformed flat. As the process progresses, the volumetric deformation of the internal body proceeds.
[0015]
Here, the pair of vertical and narrow band-shaped adhesive bands that form the regulation band is formed by a blow molding process, and in this process, the width may be narrowed within a range allowed from the viewpoint of technical, productivity, and the like. As a result, the entire width of the regulation band does not become thick and bone-like, so that uniform squeeze deformability can be secured over the entire body of the container, and the feeling of discomfort due to the bone-like vertical band when pressed is also felt Can be lost.
[0016]
Moreover, although the usage-amount of adhesive resin which forms an adhesive belt can also be decreased, since this adhesive resin is expensive normally, material cost can be restrained low.
[0017]
According to a second aspect of the present invention, in the first aspect of the present invention, a pair of restriction bands are provided in the vicinity of the left and right parting lines of the external container.
[0018]
According to the above configuration of the present invention, the front and rear surfaces of the body perpendicular to the parting line to be printed are irregularly formed by attaching the label on the front part of the normal container by positioning the regulation band in the vicinity of the parting line. It is possible to provide a container having a good appearance and high merchantability.
[0019]
According to a third aspect of the present invention, in the second aspect of the present invention, the left-right center line of the restriction band is located on the parting line.
[0020]
According to the above-described configuration of the third aspect, the regulation band can be positioned at an angle of 90 ° when viewed from the front of the container, and the appearance can be further improved. It becomes possible to make it symmetrical with respect to the connected line, and good operability and pouring property can be obtained.
[0021]
According to a fourth aspect of the present invention, in the second aspect of the invention, the right and left center line of the regulation band is shifted from the parting line.
[0022]
Since the container is usually blow-molded with a blow molding split mold having a pinch-off structure, the bottom seal part of the container body formed by the bottom pinch-off part is sandwiched between the inner layers from both sides. The outer layer and the inner layer are peelable.
[0023]
Here, the bottom seal part is formed by sandwiching a cylindrical parison from both sides with a pinch-off part of a split mold from a direction perpendicular to the direction of the parting line, and flattening the container. When the right and left center lines of the regulation band are shifted from the parting line in the main body, the adhesive band located at a position further away from the parting line is the bottom of the pair of adhesive bands forming the regulation band. In the seal portion, the seal portion is positioned closer to the center in the left-right length direction.
[0024]
For this reason, it is possible to form a portion where the inner layer and the outer layer are bonded at two positions closer to the center of the bottom seal portion, and the four portions of the bonded portion and the left and right end portions of the bottom seal portion are formed from the outer layer and the inner layer. It acts as a nodal point against deformation in the bottom seal part of the laminated body, and even when a force is applied to the bottom seal part, it can counter this force and more reliably crack the bottom seal part It becomes possible to prevent.
[0025]
According to a fifth aspect of the present invention, there is provided the invention according to the first, second, third or fourth aspect, wherein the body portion has a circular flat cross-sectional shape.
[0026]
If the trunk is cylindrical, the squeeze container can be used without worrying about the gripping direction. In the case of a circular shape, the squeeze container is usually oval or oval. It is necessary to set the width of the regulation band wider in order to obtain better pouring operability compared to those having a flat cross-sectional shape such as a shape. Since it is formed by an adhesive band, it is possible to provide a squeeze container having a cylindrical body having a similar squeeze property from any direction without the wide regulation band hindering uniformity of squeeze deformation. it can.
[0027]
According to a sixth aspect of the invention, in the first, second, third, fourth, or fifth aspect of the invention, the body portion has a flat cross-sectional shape of any one of a circular shape, an elliptical shape, and an oval shape, The band width is set to (1/4) (L-2D1). (L: circumference of flat section, D1: long diameter of flat section)
[0028]
If the width of the regulation band is set wide, the deformable part is almost eliminated due to the dimensional limit of the circumferential length of the inner layer deformation part with a large amount of contents remaining. Even if the hand is pressed, it becomes difficult to pour the contents.
[0029]
In addition, if the regulation band is set narrowly, there is a sufficient margin in the length of the inner layer deformed part, so even if a large amount of content remains as a whole container, depending on the state of the container being poured out and stored, In particular, in a portion where the content tends to decrease, the flat cross-sectional shape of the internal content almost clogs the flow passage of the content, and thereafter it becomes impossible to smoothly dispense the content.
[0030]
In the case of a circular shape, the major axis corresponds to the diameter. In the case of an ellipse and an ellipse, the parting line is usually located in the direction of the major axis in consideration of the squeeze by gripping by hand, and the regulation band is positioned. Here, by setting the width of the restriction band to (1/4) (L-2D1), the length in the circumferential direction of the inner layer deformed portion is just the length to block the flat cross section of the trunk portion by crushing due to volumetric deformation. It becomes. That is, if the ideal deformation progresses over the entire height direction, the flat cross section can be almost completely crushed in the entire height range of the internal container almost simultaneously with the completion of the content extraction, which is favorable. It is possible to maintain the pouring property and the squeeze operability almost to the end.
[0031]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
1 to 6 show an embodiment of a dispensing container according to the present invention. The container body 1 is made of a nylon resin having a low compatibility between the outer layer 16 made of a low density polyethylene resin and the low density polyethylene resin. And an adhesive layer 15 made of an adhesive resin that exhibits sufficient adhesion to a low density polyethylene resin and a nylon resin.
[0032]
The container body 1 includes a bottom portion 4, a cylindrical body portion 2, and a cylindrical mouth portion that is erected on the upper end of the body portion 2 via a shoulder portion 6 and engraved with a thread on the outer peripheral surface. 3 is a box shape.
[0033]
The height of the container body 1 is 160 mm, and the diameter of the circular flat cross section of the body 2 is 60 mm (indicated by the inner diameter).
[0034]
The outer layer 16 and the inner layer 11 forming the container body 1 are laminated so as to be peelable except for a portion of the adhesive band 32 that is bonded and fixed by the adhesive layer 15. The outer layer 16 has sufficient mechanical strength and squeeze. An outer container 17 having deformability and reversible flexibility is formed, and the inner layer 11 has a thin inner container 12 on the inner side of the outer container 17 that can freely exhibit volume reduction deformation. (See Figures 1 and 2)
[0035]
FIG. 3 is a plan sectional view of the body 2, and a pair of left and right parting lines 36 (shown in the upper and lower positions in FIG. 3) of the body 2 in a circular flat sectional shape are shown. The regulation band 31 is formed over substantially the entire height range of the container body 1.
[0036]
The regulation band 31 is composed of an adhesive band 32 formed by the outer layer 17, the inner layer 11, and the thin vertical belt-like adhesive layer 15 located at both end portions, and a non-adhesive portion 33 therebetween. The band 31 restricts the volume reduction deformation of the internal container 12, and the squeeze operability is improved.
[0037]
In this embodiment, the width of the regulation band is 17 mm calculated according to (1/4) (L-2D1), that is, (1/4) D (π-2) in the circular shape, and the width of the adhesive band 32 is 2 mm. (D represents the diameter, and π represents the circumference ratio.)
[0038]
Since the regulation band 31 is arranged on the parting line 36 in this way, the front and rear surfaces of the body part 2 perpendicular to the parting line 36 on which the label is applied or printed are usually uneven on the front surface of the container body 1. It is possible to provide a container having a good appearance and high merchantability because the regulation band 31 is not conspicuous.
[0039]
As shown in FIGS. 7 and 8, the blow molding of the container body 1 is performed by using a parison between the outer cylinder 63, the inner cylinder 62 positioned inside the outer cylinder 63, and the outer cylinder 63 and the inner cylinder 62. A pair of four vertically thin strip-like adhesive layers 15 positioned axisymmetrically with respect to the central axis of the sheet are co-extruded to form a parison 61, and the parison 61 is molded into a container body using a blow mold. 1 to form.
[0040]
In the cylindrical mouth portion 3 in which a thread is engraved on the outer peripheral surface, an intake hole 51a, which is one embodiment of the intake portion 51, is positioned 90 ° from the parting line 36 with respect to the central axis of the external container 17. A pair is formed symmetrically with respect to the axis. (See Figure 1)
[0041]
The dispensing cap body 41 has a top wall having an opening 44 formed at the center, and has a top cylindrical shape in which a thread for screwing with the mouth 3 of the container body 1 is engraved on the inner peripheral surface. A cap main body 42, and a pouring cylinder 48 erected on the opening edge of the opening 44 on the top surface of the top wall of the cap main body 42, and from the spout 43 at the tip of the pouring cylinder 48. The content 55 is poured out to the outside, and the spout 43 is covered with a cover cap 49. (See Figures 2 and 4)
[0042]
Further, the dispensing cap body 41 is assembled to the mouth portion 3 of the container body 1 by screwing, and a seal cylinder piece 48a suspended from the lower surface of the top wall of the cap body 42, and the inner periphery of the cylinder wall of the cap body 42 The seal peripheral strips 45 attached to the lower end of the surface are in close contact with the upper end of the inner peripheral surface and the lower end of the outer peripheral surface of the mouth portion 3 of the container main body 1, and are tightly assembled to the container main body 1.
[0043]
In addition, the dispensing cap body 41 is normally closed by opening the first check valve portion 46 having the first valve body 46a in the opening portion 44 of the cap body 42 so that the opening portion 44 is closed. When the container body 1 is squeezed and the contents 55 are poured out, it opens by the internal pressure of the internal container 12 and opens the opening 44. .
[0044]
The dispensing cap body 41 has a second valve body 47a that constitutes the second check valve portion 47 at a position that matches the position of the intake hole 51a provided in the mouth portion 3 on the cylindrical wall of the cap body 42. The second valve body 47a has a function of introducing external air into the interlayer 19 between the outer layer 16 and the inner layer 11 through the intake hole 51a, and a check that does not allow the air in the interlayer 19 to escape to the outside. With functions.
[0045]
Next, the usage state of the dispensing container according to the above embodiment will be described.
In the dispensing container configured as described above, when the container body 1 is squeezed, the second valve body 47a is in a closed state, and the pressure in the internal container 12 containing the contents 55 increases. Then, the first valve body 46a is opened, and the contents 55 are poured out from the spout 43 at the tip of the pouring cap body 41, and the internal body 12 is deformed and deformed accordingly.
[0046]
Here, the regulation band 31 itself is as wide as 17 mm. If the adhesive layer 15 is laminated over the entire width and the outer layer 16 and the inner layer 11 are bonded together, the body portion thereof is provided for flexibility. Compared to the outer container 17 formed relatively thin, the restriction band 31 becomes a bone-like portion that is difficult to deform, and cannot be uniformly squeezed. The bone-like part makes you feel uncomfortable.
[0047]
However, in this embodiment, since the regulation band 31 is formed by the adhesive band 32 having a width of about 2 mm, the squeeze deformability is the same regardless of the direction in which the body 2 of the container body 1 is held. And the above-mentioned uncomfortable feeling can be eliminated.
[0048]
When the squeeze of the container body 1 is stopped and the pressure on the body 2 is released, the outer container 17 starts to be restored to its original shape by an elastic recovery force, and the pressure between the outer container 17 and the inner container 12, that is, the pressure between the layers 19 As a result, the internal pressure of the internal container 12 returns to the external air pressure, the first valve body 46a is closed, and the dispensing of the contents 55 is stopped.
[0049]
When the outer container 17 is further restored to its original shape, the second valve body 47a opens while the inner container 12 retains the reduced volume deformed shape, and the interlayer 19 between the outer layer 16 and the inner layer 11 passes through the intake hole 51a. External air is sucked into the outer layer 16 and separation of the outer layer 16 and the inner layer 11 proceeds at this time.
[0050]
FIG. 5 is a plan sectional view of the trunk portion 2 of the dispensing container of the present embodiment, and is an explanatory diagram showing the transition of deformation of the inner layer 11 (inner container 12), and ideal progress of volume reduction deformation. When the situation is seen in a flat cross section, first, the inner layer deformed portions 11a and 11b divided into the left and right by the regulation band 31 are deformed into a flat shape, and this deformation proceeds and contacts on the line connecting the parting lines 36. Further, the volumetric deformation progresses while this contact progresses toward the portion where the regulation band 31 is located.
[0051]
Here, by setting the width of the regulation band 31 to 17 mm, the length in the circumferential direction of each of the pair of inner layer deformed portions 11a and 11b is 77 mm. This length is the sum of the diameter and the width of the regulation band 31. By setting the width of the restriction band 31 in this way, the flow passage 56 is provided in the vicinity of the restriction band 31 until the content 55 is substantially eliminated as shown in FIG. Therefore, it is possible to maintain a good dispensing operability until the end.
[0052]
FIG. 6 is a bottom view of an embodiment of the dispensing container according to the present invention. Since the container is blow-molded by a blow molding split mold having a pinch-off part structure, the bottom of the container body 1 formed by the pinch-off part. The seal portion 5 has a sandwich shape in which the inner layer is sandwiched between the outer layers from both sides, and the outer layer and the inner layer can be peeled off.
[0053]
FIG. 9 is an explanatory view showing the position of the adhesive layer 15 in the parison 61 and in a state where the parison 61 is pinched off, of which (a) is the left-right center line (the center in the width direction) of the regulation band 31. Is shown in the case where it is aligned with the parting line 36, and FIG.
[0054]
Compared to the adhesive layers 15a1, 15a2, 15a3, and 15a4 when the center line is arranged on the parting line, the adhesive layer 15b1 that is located farther from the parting line 36 by the parison 61 in the case of being arranged offset, 15b4 is located closer to the center in the length direction of the pinch-off portion in a state where the pinch-off is performed.
[0055]
For this reason, it is possible to form a portion where the inner layer 11 and the outer layer 16 are bonded and fixed at two positions closer to the center of the bottom seal portion 5 of the container body 1, and the right and left ends of the bonded portion and the bottom seal portion 5. A total of four parts serve as knot points against deformation in the bottom seal part 5 of the laminate composed of the outer layer 16 and the inner layer 11, and this force is applied even when a certain force is applied to the bottom seal part 5. It can counter, and it becomes possible to prevent the bottom seal part 5 from cracking more reliably.
[0056]
In addition, the flat cross-sectional shape of the trunk | drum 2 is not limited to the circular shape described in the said one Example, The shape generally used by elliptical shape, an ellipse flat cross-sectional shape, and other blow molded products In this case, the effects of the present invention are sufficiently exhibited.
[0057]
In the above embodiment, the intake portion 51 is the intake hole 51a in which a small round hole is formed in the external container 17 of the mouth portion 3. However, the intake portion 51 is not limited to this example. A slit formed by providing a pinch-off part in the mouth part 3 at the time of blow molding can also be used as the intake part 51.
[0058]
