Description

  The present invention includes a package, more specifically, a carrier such as a mask, and two storage portions that separately store a liquid such as a chemical solution impregnated in the carrier, and the 2 through the peelable seal portion. The two accommodating portions are arranged so as to face each other, and in use, the two accommodating portions are brought into communication by pressing the liquid accommodating portion, whereby the liquid accommodated in one of the accommodating portions. It is related with the package body comprised so that the support | carrier accommodated in the other accommodating part could be impregnated.

Conventionally, as this type of package, for example, there is one as shown in FIG. That is, the packaging body 12 is an extrusion that pushes out an object to be contained as shown in the figure so that the upper and lower synthetic resin sheets are overlapped and sealed, and surrounded by the sealed seal portion. The side accommodating portion 4 and the introduction side accommodating portion 5 into which the object to be accommodated in the extrusion side accommodating portion 4 is introduced are formed.
A partition seal portion 6 is formed between the extrusion side accommodation portion 4 and the introduction side accommodation portion 5, and the seal state of the partition seal portion 6 is released by pressing the extrusion side accommodation portion 4, thereby the extrusion side It is comprised so that the accommodating part 4 and the introduction side accommodating part 5 may be made into a communication state.

And the front-end | tip parts 13 and 14 which the extrusion side accommodating part 4 and the introductory side accommodating part 5 mutually oppose are formed in protrusion shape, as shown in FIG.

This type of package is based on the idea of adjusting the seal strength of the partition seal portion 6 in order to bring the extrusion side accommodation portion 4 and the introduction side accommodation portion 5 into communication. Adjustment of the seal strength is performed by means such as use of an easily peelable film, adjustment of the heat seal temperature, application of a coating agent, and the like.

However, since the conventional packaging body shown in FIG. 13 is formed such that the distal end portions 13 and 14 of the extrusion side accommodating portion 4 and the introduction side accommodating portion 5 that are opposed to each other are formed in a protruding shape. The side accommodating part 4 is pressed, and the pressing force is applied to the partition seal part in which the sealing strength is adjusted by means such as the use of an easily peelable film, the adjustment of the heat seal temperature, the application of the coating agent as described above. When trying to act, the pressing force does not always work effectively by concentrating on the portion where the projecting tip portions 13 and 14 face each other.

As a result, there is a possibility that the peeling portion in the partition seal portion that peels by applying a pressing force may be generated at a position displaced from the center portion where the protruding tip portions 13 and 14 face each other as described above. There is a possibility that the introduction of the liquid from the portion 4 to the introduction side accommodating portion 5 is not suitably performed.

Further, as a technique that approximates the package as shown in FIG. 13, for example, a patent application such as the following Patent Document 1 has been filed. In the invention according to Patent Document 1, a chemical solution is accommodated in the extrusion side accommodating portion 4, and an application stick such as a cotton swab is accommodated in the introduction side accommodating portion 5, and the extrusion side accommodating portion 4 and the introduction facing each other are introduced. A protruding portion is formed on the distal end side of the introduction side accommodating portion 5 among the distal end side with the side accommodating portion 5, a recessed portion is formed on the distal end side of the extrusion side accommodating portion 4, and the extrusion side accommodating portion 4 is pressed. Thus, the projecting portion and the recessed portion that face each other are made conductive.

Compared to the case where the distal end portions 13 and 14 of the extrusion side accommodation portion 4 and the introduction side accommodation portion 5 are both projecting like the package of FIG. By forming the protruding portion and the recessed portion at the opposed tip portions, the conductivity between the extrusion side accommodation portion 4 and the introduction side accommodation portion 5 when the extrusion side accommodation portion 4 is pressed is somewhat improved. At present, the pressing force against the side housing portion 4 has not yet been brought into effect effectively by concentrating between the front end portions where the protruding portion and the recessed portion face each other.

Therefore, there is a possibility that the peeling part in the partition seal part which peels by applying a pressing force may be generated at a position shifted from the center part where the tip part is opposed, or from the extrusion side accommodating part 4 to the introduction side accommodating part 5. However, it has not been possible to solve problems such as the possibility that the introduction of the liquid may not be suitably performed.

JP 2006-62682 A

The present invention has been made in order to solve such a problem, and the pressing force when pressing the extrusion side accommodation portion is the center where the distal end portions of the extrusion side accommodation portion and the introduction side accommodation portion face each other. It is possible to effectively act on the portion, there is no risk of causing the separation portion of the partition seal portion caused by the pressing force at a position displaced from the central portion, such as liquid from the extrusion side accommodation portion to the introduction side accommodation portion It is an object of the present invention to provide a package capable of suitably introducing an object to be contained.

The present invention has been made in order to solve the above-described problems.

  As described above, the present invention is formed such that the leading edge of the opposite introduction side accommodating portion is positioned closer to the extrusion side accommodating portion than the distal end edge of the extrusion side accommodating portion, so that the protruding portion is concave. Since it is formed so that it can protrude into the entry part, the partition seal part between such a protruding part and the recessed part is formed as a conductive seal part that conducts the extrusion side accommodating part and the introduction side accommodating part. The pressing force at the time of pressing the extruding side accommodating portion can be effectively applied to the central portion where the distal end portions of the extruding side accommodating portion and the introducing side accommodating portion face each other, and the partition seal portion generated by the pressing force There is no possibility that the peeling part is generated at a position displaced from the center part, and there is an effect that it is possible to suitably introduce an object to be accommodated such as a liquid from the extrusion side accommodating part to the introduction side accommodating part.

Hereinafter, the packaging body of one Embodiment is demonstrated according to drawing. As shown in FIGS. 1 to 3, the packaging body 12 according to one embodiment includes a planar rectangular upper sheet 1 and a planar rectangular lower sheet 2. The upper sheet 1 and the lower sheet 2 are composed of synthetic resin sheets. Although it does not specifically limit as a synthetic resin, For example, polyethylene, a polypropylene, a polyethylene terephthalate etc. can be used.

The peripheral part of the upper sheet 1 and the lower sheet 2 is formed with a seal part 3 by heat sealing, ultrasonic sealing or the like, and the part surrounded by the seal part 3 at the peripheral part is not sealed, as shown in FIG. As shown, two accommodating portions having a space in which an object can be accommodated are formed between the upper sheet 1 and the lower sheet 2.

One of the two storage portions is an extrusion-side storage portion 4 that pushes out an object to be stored by pressing, and mainly stores a liquid such as a chemical solution. However, as will be described later, in place of the liquid, it is also possible to accommodate a highly viscous liquid such as an emulsion, ointment, cream or the like. The other of the two accommodating portions is an introduction-side accommodating portion 5 that introduces an object to be extruded extruded from the extrusion-side accommodating portion 4 and is an object to be extruded from the extrusion-side accommodating portion 4. A carrier such as a mask that is impregnated with a liquid or the like is mainly accommodated. However, as will be described later, instead of the carrier impregnated with the liquid or the like, it is also possible to accommodate a powder or the like that is dissolved in the liquid.

In the present embodiment, a case is described in which a liquid is stored in the extrusion-side storage portion 4 and a chemical solution such as a skin lotion or a disinfecting liquid is used as the liquid, and a carrier is stored in the introduction-side storage portion 5. A case where a carrier such as a mask or a nonwoven fabric pad is used as the carrier will be described.

A partition seal portion 6 is formed between the extrusion side storage portion 4 and the introduction side storage portion 5 so as to be continuously sealed by the seal portion 3 at the peripheral edge. The extrusion side accommodating portion 4 and the introduction side accommodating portion 5 are partitioned. The central portion of the partition seal portion 6 is formed to be the thinnest, and is formed as a conductive seal portion 7 that electrically connects the extrusion side accommodation portion 4 and the introduction side accommodation portion 5 during use. The partition seal portion 6 including the conductive seal portion 7 is sealed by a so-called easy peel. Here, the easy peel means sealing by adjusting the temperature, time, etc. at the time of heat welding without using a chemical for adjusting the seal strength.

As shown in FIG. 1, the extrusion-side accommodating portion 4 is formed by being surrounded by a pair of opposed long side edges 4a and 4b and a pair of opposed short side edges 4c and 4d. . The pair of long side edges 4a and 4b are formed in a straight line as shown in FIG. Of the pair of short side edges 4c and 4d, the outer short side edge 4c is linear in a state in which three sides of a rectangle are formed orthogonal to the long side edges 4a and 4b. Is formed.

On the other hand, among the pair of short side edges 4c and 4d, the central short side edge 4d is formed in a substantially semicircular shape as shown in FIGS. And the recessed part 8 notched so that arc shape might be drawn is formed in the front end side of the short side edge part 4d of the center side formed in this substantially semicircle shape.

As shown in FIG. 1, the introduction side accommodating portion 5 is formed so as to be surrounded by a pair of opposed long side edges 5a and 5b and a pair of opposed short side edges 5c and 5d. . The pair of long side edges 5a and 5b are formed in a straight line as shown in FIG. In addition, of the pair of short side edges 5c and 5d, the outer short side edge 5c is linear in a state of forming three rectangular sides orthogonal to the long side edges 5a and 5b. Is formed.

Of the pair of short side edges 5c and 5d, the short side edge 5d on the center side is formed in a straight line as shown in FIGS. 1 and 2, but the short side edge on the center side. A portion where the portion 5d intersects the longitudinal side edge portions 5a and 5b is formed in a small arc shape. Accordingly, the introduction side accommodating portion 5 is formed in a substantially rectangular shape as a whole, and only a portion where the short side edge portion 5d and the long side edge portions 5a and 5b intersect with each other is formed with a rounded shape. A projecting portion 9 that projects in an arc shape is formed on the center front end side of the short side edge portion 5d.

Here, as shown in FIG. 2, the distal end portion 9 a of the protruding portion 9 of the introduction side accommodating portion 5 is extruded by the dimension t from both side edge portions 8 a and 8 a of the recessed portion 8 of the extrusion side accommodating portion 4. It is located on the side housing 4 side. As a result, the protruding portion 9 of the introduction side accommodating portion 5 is formed in a state where it protrudes into the recessed portion 8 of the extrusion side accommodating portion 4 as shown in FIG.

In the state manufactured as the package body 12, the extrusion-side accommodation portion 4 contains the liquid 10 as shown in FIG. 4, and the introduction-side accommodation portion 5 contains the carrier 11 as shown in FIG. 4. Yes. In other words, FIG. 3, which is a cross-sectional view taken along the line AA in FIG. 1, is shown in a state in which both the inside of the extrusion-side accommodation portion 4 and the introduction-side accommodation portion 5 remain in space, for convenience of explanation. In the state where the package is actually manufactured, the liquid 10 and the carrier 11 which are the objects to be contained are accommodated in the extrusion side accommodating portion 4 and the introduction side accommodating portion 5 as shown in FIG. .

And when using the package 12 which consists of such a structure, the extrusion side accommodating part 4 in which the liquid is accommodated is first pressed with a finger | toe etc. FIG. By pressing the extrusion side accommodating part 4 in this way, the pressure in the extrusion side accommodating part 4 is increased, and the pressure is a concave formed at the tip of the extrusion side accommodating part 4 as shown in FIG. It acts on the entrance 8.

In this case, the partition seal portion 6 that divides the extrusion-side accommodation portion 4 and the introduction-side accommodation portion 5, particularly the conduction seal portion 7 between the recessed portion 8 of the extrusion-side accommodation portion 4 and the protruding portion 9 of the introduction-side accommodation portion 5. However, since it is sealed with an easy peel, when a force exceeding the seal strength of the easy peel is applied, the conduction seal portion 7 gradually peels off, and as shown in FIG. A part of the liquid in 4 is extruded.

Further, by applying a pressing force, the entire conductive seal portion 7 is peeled off, and the extrusion side accommodating portion 4 and the introduction side accommodating portion 5 are brought into a conductive state. Then, when the conduction seal portion 7 is peeled and the extrusion side accommodation portion 4 and the introduction side accommodation portion 5 are in the conduction state, the liquid pushed out from the extrusion side accommodation portion 4 is introduced into the introduction side as shown in FIG. The carrier 11 introduced into the housing part 5 and impregnated in the carrier 11 housed in the introduction side housing part 5 is impregnated.

  In this case, the short side edge 4d on the center side of the extrusion side accommodating part 4 is formed in a substantially semicircular shape, and an arc shape is drawn on the tip side of the substantially semicircular short side edge 4d. Therefore, the pressing force applied to the extrusion side accommodating portion 4 is concentrated on the concave portion 8 which is the tip and the central portion of the extrusion side accommodating portion 4 and effectively acts. To do.

Furthermore, a protruding portion 9 that protrudes in an arc shape is formed at the distal end portion of the introduction side accommodating portion 5, and the distal end portion 9 a of the protruding portion 9 is a concave portion of the extrusion side accommodating portion 4. The protruding portion 9 of the introduction side accommodating portion 5 is located inside the recessed portion 8 of the extruding side accommodating portion 4 so as to be located closer to the extruding side accommodating portion 4 than the both side edge portions 8a, 8a of the insertion portion 8 by the dimension t. Therefore, the pressing force that acts intensively on the recessed portion 8 that is the tip and central portion of the extrusion side accommodating portion 4 as described above is exposed to the recessed portion 8. It also acts suitably on the protruding portion 9 of the introduced introduction side accommodating portion 5.

As a result, the pressing force acting on the partition seal portion 6 between the extrusion-side accommodation portion 4 and the introduction-side accommodation portion 5 in addition to the extrusion-side accommodation portion 4 is a recessed portion that is the front end and the central portion of the extrusion-side accommodation portion 4. 8 and the conductive seal portion 7 between the projecting portion 9 of the introduction side accommodating portion 5 formed so as to protrude into the recessed portion 8. Accordingly, inadvertent peeling does not occur in the portion of the partition seal portion 6 other than the conductive seal portion 7, that is, in the portion of the partition seal portion 6 that is displaced from the center, and the peeling is concentrated on the conductive seal portion 7. Since the force acts, the liquid in the extruding side accommodating portion 4 is not inadvertently leaked, and the liquid in the extruding side accommodating portion 4 is preferably introduced via the portion that has become conductive. 5 will be introduced.

In addition, since the peeling force acts effectively by concentrating on the conductive seal portion 7, even if the woman or the elderly is generally weak, the conductive seal portion 7 is peeled off, and the extrusion side accommodating portion 4 and the introduction side are separated. The operation | work which electrically connects with the accommodating part 5 can be performed easily.

The liquid introduced into the introduction side accommodating portion 5 from the extrusion side accommodating portion 4 in a conductive state is suitably impregnated in the carrier 11 accommodated in the introduction side accommodating portion 5.

In addition, in the said embodiment, although the upper sheet 1 and the lower sheet 2 which comprise the package 12 demonstrated the case where it comprised with polyethylene, a polypropylene, a polyethylene terephthalate, etc., the upper sheet 1 and the lower sheet 2 of The material is not limited to this, and other synthetic resins can be used. In the present invention, the package 12 is made of a synthetic resin. Therefore, the upper sheet 1 and the lower sheet 2 are mainly made of a synthetic resin. It is also possible to use it.

Moreover, in the said embodiment, the extrusion side accommodating part 4 is enclosed and formed by a pair of opposing long side edge part 4a, 4b, and a pair of opposing short side edge part 4c, 4d, and a pair The long side edge portions 4a and 4b and the outer short side edge portion 4c are linear, and the short side edge portion 4d on the center side is formed in a substantially semicircular shape.

It is not a thing.

Furthermore, in the above embodiment, the partition seal portion 6 including the conductive seal portion 7 that conducts the extrusion side accommodating portion 4 and the introduction side accommodating portion 5 is sealed by the easy peel.
It is not an essential condition for the present invention to seal the partition seal portion 6 with an easy peel.

However, according to the technique of applying a chemical to the sheet to adjust the sealing strength, such as part coating, and heat welding, there is a possibility that uniform sealing strength cannot be obtained due to uneven application of the chemical applied to the sheet. On the other hand, since such a problem does not occur in the easy peel, it is desirable to adopt an easy peel method of sealing by adjusting the temperature, time, etc. at the time of heat welding.

Moreover, in the said embodiment, sealing of the division seal part 6 containing the sealing part 7 for conduction | electrical_connection by an easy peel is demonstrated, and the seal | sticker of the surrounding seal part 3 surrounding the extrusion side accommodating part 4 and the introduction side accommodating part 5 is demonstrated. Although there is no particular reference to the above, the surrounding seal portion 3 may be set to have a higher sealing strength than the easy peel, or may be sealed with an easy peel. In any case, these seals can be performed by heat welding, ultrasonic welding, high frequency welding, or the like.

Furthermore, in the said embodiment, although the extrusion sheet | seat side accommodating part 4 and the introduction side accommodating part 5 were formed by sealing two sheets, the upper sheet | seat 1 and the lower sheet | seat 2, it is using two sheets | seats. This is not an essential condition for the present invention. For example, the extrusion-side accommodation portion 4 and the introduction-side accommodation portion 5 are formed by folding one sheet into two and sealing the facing sheet portion folded into the two. It is also possible.

  Furthermore, although the said embodiment demonstrated the case where a chemical | medical solution like a lotion and disinfecting liquid was used as a liquid accommodated in the extrusion side accommodating part 4, it can also be used for liquids other than this. Further, in this embodiment, the case where a carrier such as a mask impregnated with a chemical solution or a non-woven pad is used as the carrier, but the type of carrier is not limited to this embodiment.

Furthermore, the property of the object to be accommodated in the extrusion side accommodating portion 4 is not limited to the liquid of the above embodiment, and it is also possible to accommodate things such as emulsions, ointments, creams and the like.

Furthermore, in the said embodiment, although the case where the liquid was accommodated in the extrusion side accommodating part 4 and the support | carrier was accommodated in the introduction side accommodating part 5 was demonstrated, it is not restricted to this, For example, in the introduction side accommodating part 5 It is also possible to use a case where a medicine and other powders are accommodated and the liquid in the extrusion side accommodating part 4 is introduced into the introduction side accommodating part 5 to dissolve the powder in the liquid.

  Further, the use of the package of the present invention is not limited to cosmetics, pharmaceuticals, foods, etc., and can be used for other purposes.

The leading end 9 a of the portion 9 is not located on the side of the extrusion side accommodating portion 4 with respect to the side edge portions 8 a and 8 a of the recessed portion 8. Therefore, in Comparative Example 2, the protruding portion 9 does not protrude into the recessed portion 8 as in the first embodiment, and is simply formed so that the protruding portion 9 and the recessed portion 8 face each other. It ’s just that. These points are different from the first embodiment.

As shown in FIG. 12, the package 12 of Comparative Example 4 has a pair of long side edges 4a, 4b and short side edges 4c, 4d of the extrusion side accommodating part 4 all formed in a straight line. Further, the long side edges 5a and 5b and the outer short side edge 5c of the introduction side accommodating part 5 are formed in a straight line, and the short side edge 5d on the center side is formed in a gentle arc shape. . The recessed portion 8 and the protruding portion 9 as in the first embodiment are not formed, and in any case, the shapes of the extrusion side accommodation portion 4 and the introduction side accommodation portion 5 are significantly different from those in the first embodiment.

Using the packaging bodies 12 of Example 1 and Comparative Examples 1 to 4 as described above, a pressure peak strength test was performed. The pressure peak strength test was performed based on the heat seal strength test in JIS Z 0238. The withstand pressure peak intensity was measured five times, and the average value was obtained. The test results are shown in Table 1.

As is apparent from Table 1, the average value of the pressure-resistant peak strength tested with the packaging bodies 12 of Comparative Examples 1 to 4 was about 100 to 170 (N / pack), whereas the packaging of Example 1 was used. The average value of the pressure-resistant peak intensity tested with the body 12 was about 55 (N / pack), which was significantly lower than those of Comparative Examples 1 to 4. Therefore, when the extrusion side accommodation part 4 is accommodated in the extrusion side accommodation part 4 and the introduction side accommodation part 5 of the packaging body 12 of Example 1 and the extrusion side accommodation part 4 is pressed, the packaging body 12 of Comparative Examples 1 to 4 is used. Compared to the case where liquid and carrier are accommodated in the extrusion side accommodating part 4 and the introduction side accommodating part 5 and the extrusion side accommodating part 4 is pressed, respectively, the partition seal portion between the extrusion side accommodating part 4 and the introduction side accommodating part 5 It is predicted that peeling of the film is remarkably easy.
