Description

Container body

The present invention relates to a container body, and more particularly to a container body that houses a bag body in which contents are enclosed.

Conventionally, various container structures have been proposed for storing solid or gel-like contents containing volatile and sublimable components such as fragrances and insect repellents. In these container structures, when the contents are installed or refilled, there is a possibility that the contents may come into contact with the fingers and the drug adheres, so it was necessary to take hygiene measures and safety measures .

In order to solve these problems, Patent Document 1 discloses that a pack body is accommodated in a container, a free piece is formed on a laminate film of the pack body, a tow rope is attached, and the container is led out from the outlet of the container. A structure has been proposed in which the contents are exposed in the container without touching the contents containing the drug by opening the pack body by pulling the tow rope.

Further, in Patent Document 2, a sealing bag is installed in a case, an end portion of the sealing bag is derived from an opening provided on a side surface of the case, and the sealing bag is opened from a V-cut of the derived end portion. Thus, there has been proposed a structure in which air is introduced into a medicine bag sealed in a sealed bag.

However, in the prior art of Patent Document 1, the structure of the pack body is complicated. Further, when the pack body is installed in the container, it is necessary to match each part of the container and each structure of the pack body, and there is a problem that the work efficiency of installation and refilling of the pack body is poor.

Moreover, in the prior art of patent document 2, since air flows in and out of the medicine bag only from the opening provided on the side surface of the case, the direction of volatilizing the contents is limited to the side surface, and the chemical volatilization effect in the upward direction of the case Difficult to get. Further, in order to suppress the adhesion of the drug to the periphery of the case, it is necessary to volatilize the drug in the upward direction and suppress the drug volatilization in the side direction. However, in the prior art of Patent Document 2, drug volatilization occurs from the side opening to the side surface, and it is difficult to prevent the drug from adhering to the periphery of the case, and the amount of drug volatilization outside the side direction is appropriately designed. There was a problem that it became difficult.

The present invention has been made in view of the above-described conventional problems, and the contents containing a volatile drug can be exposed in a container using a bag body with a simple structure, and in the lateral direction. It is an object of the present invention to provide a container body capable of suppressing chemical volatilization.

In order to solve the above-mentioned problem, a container body of the present invention is a container body including a content, a bag body that encloses the content, and a container that houses the bag body, and is near one end of the bag body. Is extended to the outside while being held across at least one side surface portion of the container, and the tensile strength of the bag body is in a range of 0.5 N / 15 mm to 100 N / 15 mm.

In such a container body of the present invention, by pulling one end of the bag body sandwiched between the side portions, the bag body can be removed from the container and the contents can be left in the container, and the contents can be stored with a simple structure. It can be exposed in the container without touching it with a finger. Further, since the vicinity of one end of the bag body is sandwiched by the side surface portion of the container, it is not necessary to provide an opening in the side surface portion, and volatilization of the contents in the side surface direction can be suppressed.

Moreover, in 1 aspect of this invention, the loop rigidity of the said bag is 0.02 mN or more and 200 mN or less.

Moreover, in 1 aspect of this invention, the thickness of the said bag body is the range of 2 micrometers or more and 600 micrometers or less.

FIG. 3 is a schematic view showing the bag 30 and the drug impregnated body 40 of the present embodiment, FIG. 3 (a) is a schematic sectional view, and FIG. 3 (b) is a schematic perspective view. The bag body 30 is formed by sandwiching a drug-impregnated body 40 between two

films

31a and 31b, and sealing the periphery of the drug-impregnated body 40 with an adhesive. The drug-impregnated body 40 is a content sealed inside the bag body 30, an impregnated body capable of holding a liquid body therein, essential oils such as peppermint oil, lemon oil, clove oil, eucalyptus oil, and fragrance components Volatile and sublimable, such as insecticides such as, transfluthrin, metfurthrin, enpentrin, profluthrin, camphor, naphthalene, paradichlorobenzene, and fungicides such as isopropylmethylphenol, parachlorometaxylenol, iodine, allyl isothiocyanate, chlorine dioxide Soaked with drugs. The drug impregnated body 40 may be a solid drug composed only of a sublimable drug. The volatile drug and the sublimable drug may be any substance that volatilizes and sublimes at room temperature, and examples thereof include known insecticides, repellents, fragrances, and bactericides.

The

films

31a and 31b must be made of a material that does not allow permeation of the drug volatilized from the drug-impregnated body 40, which is the content. Ethylene-vinyl alcohol copolymer (EVOH), polyacrylonitrile (PAN), and the like. The film may contain a metal such as aluminum. An end region 32 where the drug impregnated body 40 is not located is provided in the vicinity of one end in the longitudinal direction of the bag body 30, and a V-shaped cut 33 is formed on both sides of the end region 32 with a part cut away. Has been. The formation position of the V-shaped cut 33 in the bag body 30 is inside the region where the

films

31a and 31b are bonded with an adhesive in the longitudinal direction, and within the range of the region where the adhesive is bonded on both sides in the width direction. is there.

FIG. 4 is a schematic perspective view showing a state before the bag body 30 and the drug impregnated body 40 are placed on the container lower part 20 and the container upper part 10 is combined. As shown in FIG. 4, the bag body 30 is placed on the bottom surface 23 so that the longitudinal direction of the bag body 30 is substantially parallel to the lower locking side surface 22. At this time, the drug-impregnated body 40 enclosed in the bag body 30 is located at a substantially central portion of the bottom surface 23 and is placed on the pedestal portion 26 (not shown) via the film 31b. In addition, the longitudinal direction of the bag body 30 is formed longer than between the two opposing drawing side surfaces 11 and 21, and the end region 32 and the V-shaped cut 33 in the vicinity of one end thereof are located outside the lower drawing side surface 21. It is extended and placed. After the bag body 30 is placed, the container lower part 20 is moved from the upper part to the container upper part 10 after being aligned, and the container body 1 of the present embodiment shown in FIG. 1 is obtained by combining both.

The container body 1 of this embodiment will be described with reference to FIGS. 1 and 5 again. FIG. 5 is a cross-sectional view of the container body 1 at the position indicated by the line AA in FIG. In the container body 1 in a state where the container upper portion 10 and the container lower portion 20 are combined, the upper drawer side surface 11 and the lower drawer side surface 21 are in close contact with each other in the end region 32 of the bag body 30 in the entire width direction. It is clamped over the entire width by the side surface 11 and the lower extraction side surface 21 and extends to the outside. As shown in FIG. 5, the width direction of the bag body 30 is shorter than between the two lower locking side surfaces 22, and the end sides are not sandwiched between the upper locking side surface 12 and the lower locking side surface 22.

As described above, the lower end of the upper drawer side surface 11 and the upper end of the lower drawer side surface 21 are both formed to be flush with each other and are designed to come into contact with each other when the container upper portion 10 and the container lower portion 20 are combined. Yes. Further, the upper end of the support portion 24 has a shape corresponding to the top surface 13, and when the locking claw 16 and the locking groove 25 are fitted, the top surface 13 and the locking claw 16 support the support portion. 24 is gripped and movement of the container upper part 10 in the vertical direction is restricted.

Since the container upper part 10 and the container lower part 20 are formed of resin, the container upper part 10 and the container lower part 20 including the fitting portion of the locking claw 16 and the locking groove 25 can be somewhat elastically deformed. . Therefore, even when the end region 32 of the bag body 30 is sandwiched between the upper drawer side surface 11 and the lower drawer side surface 21, the latching claw 16 and the latching groove 25 can be fitted to each other. The container lower part 20 is combined with the movement in the vertical direction and the horizontal direction being restricted.

Next, the usage method of the container body 1 of this embodiment is demonstrated using FIG. First, the bag body 30 is torn in the width direction from the V-shaped cut 33 of the one end region 32, cut in an area where the

films

31a and 31b are not bonded, and the bag body 30 is opened. Next, the other end region 32 opposite to the cut side is pinched with a finger or the like, and the bag body 30 is pulled out from between the upper drawer side surface 11 and the lower drawer side surface 21.

At this time, by pulling the bag body 30 from the other side, the entire bag body 30 including the drug-impregnated body 40 moves. However, since one end region 32 of the bag body 30 is cut and opened by the V-shaped cut 33 and the bag body 30 is sandwiched between the upper drawer side surface 11 and the lower drawer side surface 21, the drug impregnated body 40. Only the movement of is inhibited. As a result, the drug-impregnated body 40 is removed from the bag body 30 and at the same time remains inside the container upper part 10 and the container lower part 20 and is exposed. From the exposed drug impregnated body 40, the drug volatilizes and is diffused to the outside through the volatilization port 14.

FIG. 6 is an external perspective view showing the container body 1 with the bag body 30 removed. As shown in the figure, the upper drawer side surface 11 and the upper locking side surface 12 of the container upper portion 10 are combined in a state of being in close contact with the lower drawer side surface 21 and the lower locking side surface 22 of the container lower portion 20. Therefore, the drug is not diffused from the side surface direction of the container body 1, and the drug is diffused only from the plurality of volatilization ports 14 formed on the top surface 13. Thereby, the drug impregnated body 40 which is a content containing a volatile drug can be exposed in the container using the bag 30 having a simple structure, and the drug volatilization in the lateral direction can be suppressed. It becomes possible.

As described above, in the present invention, the opened bag body 30 is pulled out from the gap between the upper drawer side surface 11 and the lower drawer side surface 21, and the drug-impregnated body 40 enclosed in the bag body 30 is placed inside the container body 1. Leave it exposed. Therefore, the two

films

31 a and 31 b constituting the bag body 30 need to be formed of a material that can be satisfactorily pulled out from the gap between the upper drawer side surface 11 and the lower drawer side surface 21.

When the bag body 30 is pulled out, the drug impregnated body 40 moves together with the two

films

31a and 31b. At this time, the

films

31 a and 31 b covering the upper and lower surfaces of the drug-impregnated body 40 are separated by about the thickness of the drug-impregnated body 40. However, the movement of the drug impregnated body 40 is blocked near the upper drawer side surface 11 and the lower drawer side surface 21, and only the

films

31 a and 31 b are pulled out from the gap between the upper drawer side surface 11 and the lower drawer side surface 21. At that time, in the vicinity of the upper drawing side surface 11 and the lower drawing side surface 21, deformation of the

films

31 a and 31 b that are about half the thickness of the drug impregnated body 40 in the height direction occurs. Accordingly, the

films

31a and 31b are required to have a loop rigidity that allows the deformation to be easily performed, and may be in a range of 0.02 mN to 200 mN, preferably in a range of 0.1 mN to 150 mN, and preferably in a range of 0.5 mN to 100 mN. The following ranges are more preferable. The loop rigidity is a numerical value of the repulsive force when a film cut into a strip shape is made into a loop shape and the loop is crushed. It is measured using a loop step tester, and measured under the conditions of a temperature of 23 ° C. (± 2 ° C.), a relative humidity of 50% (± 5%), a film width of 25 mm, a clamp width of 117 mm, and a crushing distance of 20 mm.

Further, when the bag body 30 is pulled out, the outward force applied to the end region 32 on the

films

31a and 31b and the container body 1 direction by clamping in the gap between the upper drawer side surface 11 and the lower drawer side surface 21. Is applied. Therefore, the

films

31a and 31b are required to have a tensile strength that does not cause breakage or deformation even when a tensile force is applied in the longitudinal direction, and can be pulled out from the gap between the upper drawer side surface 11 and the lower drawer side surface 21. The range may be 0.5 N / 15 mm or more and 100 N / 15 mm or less, preferably 5 N / 15 mm or more and 100 N / 15 mm or less, and more preferably 10 N / 15 mm or more and 100 N / 15 mm or less. The tensile strength is measured according to the measuring method of JIS K7127.

Even if the

films

31a and 31b of the bag body 30 have the above-described tensile strength, if the frictional force between the

films

31a and 31b and the upper drawer side surface 11 and the lower drawer side surface 21 is too great, A force exceeding the strength is applied, and the bag 30 is broken or deformed. Therefore, the

films

31a and 31b of the bag body 30 must have a friction coefficient that does not break or deform even when the maximum static frictional force and dynamic frictional force are applied, and the static friction coefficient is in the range of 0.01 to 0.9. preferable. In particular, it is preferable that the container upper part 10 and the container lower part 20 are formed of PET resin, and the

films

31a and 31b are formed of nylon or an ethylene-vinyl alcohol copolymer.

Further, the bag body 30 needs to have a thickness that can be held between the upper drawer side surface 11 and the lower drawer side surface 21, and the container upper portion 10 is combined with the container lower portion 20 and locked with the bag body 30 placed thereon. In order to facilitate the operation of fitting the claw 16 into the locking groove 25, the total thickness of the

films

31a and 31b is preferably in the range of 2 μm to 600 μm.
