  Furthermore, the packaging container of this invention opens and closes the opening / closing lid 4 from one side of the upper body 1 to the other side.

  The packaging container according to the present invention is provided with a raised portion 6 having an inclined surface 6a inclined inward from the outside on the bottom plate 2a of the lower body 2 at a position below the outlet 5 of the upper body 1. It is said.

  Further, in the packaging container of the present invention, the upper body 1 and the lower body 2 are made of low density polyethylene.

  Since the packaging container of this invention is configured as described above, a plurality of film-like or sheet-like articles that easily get wet are stacked and stored in the container, and the opening / closing lid is closed. Even when stored for a long period of time, moisture does not easily enter the container, and the articles can be taken out one by one without being attracted to each other.

  Hereinafter, embodiments of the packaging container of the present invention will be described in detail with reference to the drawings.

  FIGS. 1-5 has shown one Embodiment of the packaging container of this invention, FIGS. 6-10 has shown other embodiment of the packaging container of this invention, and all are substantially rectangular shape. The upper body 1 and the lower body 2 are formed, and a plurality of film-like or sheet-like articles (not shown) that are easily dampened are stacked and stored in the container.

  It is assumed that the upper body 1 has an open lower surface, an outer peripheral wall 1b is provided around the top plate 1a, an inner peripheral wall 1c is provided inside the outer peripheral wall 1b, and the upper body 1 is provided between the outer peripheral wall 1b and the inner peripheral wall 1c. It is assumed that the fitting groove 3 is provided, and an outlet 5 in which an opening / closing lid 4 is attached to the top plate 1a is provided.

  The open / close lid 4 is provided with an outer peripheral wall 4b around the top plate 4a, and an inner peripheral wall 4c is provided inside the outer peripheral wall 4b. When the open / close lid 4 is closed, the lower end of the outer peripheral wall 4b is at the outlet 5. The inner peripheral wall 4c is fitted to the outlet 5 while contacting the peripheral surface 5a. The inner peripheral wall 4c and the outlet 5 are simple in shape and are easy to adjust the dimensions of both.

  Furthermore, in the embodiment shown in FIGS. 1 to 5, the opening / closing lid 4 opens and closes from one side portion of the upper body 1 to the substantially central portion. In the embodiment shown in FIGS. Although it opens and closes from one side part of 1 to the other side part, as another embodiment, although not illustrated, it is also possible to open and close from the substantially central part of the upper body 1 to one side part. it can.

  Further, it is assumed that a hanging body 4d is provided at an appropriate location on the outer peripheral wall 4b of the opening / closing lid 4 to hang a finger and pull it up when the opening / closing lid 4 is opened. When the opening / closing lid 4 is opened / closed from approximately the center of the upper body 1 to one side, it is necessary to form a recess (not shown) in the opening / closing lid 4 as described in the background section. Yes, dust accumulates in this recess, or it is difficult for a finger to hook on the hanging body 4d protruding into the recess, but the opening / closing lid 4 can be opened and closed from one side of the upper body 1 to approximately the center, When opening and closing from one side of the upper body 1 to the other side, there is no need to provide a recess in the opening / closing lid 4, so that dust does not collect and it is difficult to put a finger on the hanging body 4d. There is nothing.

  Further, when the upper body 1 is manufactured, when the opening / closing lid 4 is opened and closed from one side of the upper body 1 to the substantially central portion, the opening / closing lid 4 is erected vertically as shown in FIG. Since the mold can be removed only in the state, a horizontal slide mold is required in addition to the upper and lower molds, and the number of molds increases and the mold removal becomes complicated. If it opens and closes to the other side, the opening / closing lid 4 can be laid out horizontally as shown in FIG. 8, so that only the upper and lower dies can be used, and the number of dies can be reduced easily. become.

  The lower body 2 is assumed to have an open upper surface, and a peripheral wall 2b is provided around the bottom plate 2a. The peripheral wall 2b is fitted into the fitting groove 3 of the upper body 1 so as to be in close contact with the upper body 1. Are attached. Further, the lower body 2 is provided with a raised portion 6 having an inclined surface 6a inclined inward from the outside on the bottom plate 2a at a position below the outlet 5 of the upper body 1. The inclined surface 6a of the raised portion 6 is provided to facilitate removal by sliding one end of the article when the article stored in the container is taken out by finger operation. When the outlet 5 is circular, the raised portion 6 allows the article stored in the container to be taken out from the substantially central portion of the outlet 5, and the article is caught around the outlet 5. Since it does not take, it becomes easy to take out.

  Moreover, the said protruding part 6 can be made higher than the surrounding wall 2b of the lower body 2, and if the protruding part 6 is made high in this way, the inclined surface 6a will also become high according to this protruding part 6, and an inclination angle will be enlarged. As a result, one end of the article stored in the container can be lifted at a steep angle, and the article can be taken out more easily. In addition, in the case where the inclined surface 17 is formed by pushing up the bottom plate 12b of the lower body 12 as described in the background art section, the inclined surface 17 cannot be made higher than the peripheral wall 12a of the lower body 12, and the inclined surface 17 is inclined. Since the angle is also limited, one end of the article stored in the container cannot be lifted at a steep angle, and the article is not so easy to take out.

  The upper body 1 and the lower body 2 are made of a synthetic resin molded product such as polypropylene or polyethylene, but it is assumed that the upper body 1 and the lower body 2 are improved in adhesion because they are made of low-density polyethylene. This is preferable. The open / close lid 3 is attached to the upper body 1 through a thin part t as an integral molding of synthetic resin.

  As an article stored in the packaging container of the present invention, for example, a product in which a plurality of films or sheets made of an edible water-soluble polymer substance such as an oblate containing an aromatic component or a medicinal component is stacked. Can be mentioned.

  The packaging container according to the present invention configured as described above contains a film or sheet-like article in which a plurality of moisture-like articles are stacked in a container, and then is stored in the upper body 1 and the lower body 2. Shall be attached closely. In order to take out the article from the packaging container according to the present invention, a finger is put on the hanging body 4d of the opening / closing lid 4, the opening / closing lid 4 is opened as shown in FIGS. Is inserted, and the uppermost article stacked in plural is pressed with a finger, and a finger operation is performed so that one end of the article slides on the inclined wall 6a of the raised portion 6, so that the article can be easily taken out from the outlet 5. be able to. By repeating this finger operation, the articles can be taken out from the container one after another and consumed.

  Further, in the packaging container of the present invention, when the article is stored in the container and the opening / closing lid 4 is closed, the lower end portion of the outer peripheral wall 4b of the opening / closing lid 4 comes into contact with the peripheral surface 5a of the outlet 5. At the same time, since the inner peripheral wall 4c is fitted to the outlet 5, the opening / closing lid 4 and the outlet 5 are double-sealed, the degree of sealing of both is perfect, and the peripheral wall 2b of the lower body 2 is Since the lower body 2 is fitted in the fitting groove 3 of the upper body 1 and attached to the upper body 1 in close contact with each other, the degree of sealing between the upper body 1 and the lower body 2 is perfect, and the inside of the container It is difficult for moisture to enter, and even when an article stored in the container is stored for a long period of time, the article does not become damp.
