  On the other hand, the contents of some contents may change due to the influence of sunlight, fluorescent lamps, etc. (ultraviolet light, visible light, etc.). This can be reduced to some extent. Therefore, if the container body of the container with the base cup is covered with a covering such as a label or a film to form a covering container with a base cup, the influence of sunlight is reduced to some extent by the covering covering the container body and the base cup. It is considered possible.

  However, it is difficult to cover the entire container body including the bottom with a covering such as a label or a film. Further, in the base cup, as described above, a drain hole is formed in the bottom wall. In this case, depending on the storage state of the container, such as being displayed on a net shelf, light such as lighting by a fluorescent lamp directly hits the container main body from the drain hole formed in the bottom wall of the base cup. Become. For this reason, in a conventional container with a base cup, there is room for improvement in light-shielding properties only by covering the container body with a covering, and it is necessary to take additional measures to guarantee the quality of the contents over a long period of time. .

  The problem to be solved is based on the fact recognition mentioned above, and it is possible to ensure air permeability (drainage) between the base cup and the light without direct exposure to the bottom of the container body. An object of the present invention is to provide a covered container with a base cup.

Air permeability (drainage) between the base cup can also be ensured. Therefore, according to the coated container with a base cup of the present invention, air can be secured between the base cup without direct exposure to the bottom of the container body (drainage). Therefore, it has an excellent effect as a container filled with contents that are easily affected by light.

  Hereinafter, with reference to drawings, the covering container with a base cup which is one form of this invention is demonstrated in detail.

  FIG. 1 is a cross-sectional view showing a main part of a coated bottle 100 with a base cup according to the first embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view showing the main part.

  As shown in FIG. 1, a covered bottle 100 with a base cup includes a bottle main body (container main body) 110 for filling contents, a base cup 120 mounted on the bottom 111 of the container main body 110 and holding the container main body 110 independently. A film sheet (covering body) 130 for covering the bottle body 110 and the base cup 120 is provided.

  The bottle main body 110 is made of PET resin, and its bottom 111 has a small diameter by Δφ (= φ1−φ2) with respect to the body 112, as shown in FIG. The bottom portion 111 includes a cylindrical portion 111a that hangs down from a step with the body portion 112, an annular inclined portion 111b that is connected to the cylindrical portion 111a and extends from the cylindrical portion 111a toward the bottle axis О, and the inclined portion 111b. The dome portion 111d is connected to the end 111c of the portion 111b and protrudes from the end 111c toward the bottle axis O toward the inside of the bottle. According to such a shape, moisture or the like adhering to the surface of the bottle 110 in the base cup 120 flows down toward the end 111c of the bottom 111 in a hot water shower or the like in the heat sterilization process.

  The base cup 120 is mainly composed of PP (polypropylene) resin or PE (polyethylene) resin, and is connected to the flat bottom wall 121 and the edge 122 of the bottom wall 121 to fit the bottom 111 of the bottle body 110. It consists of a peripheral wall 123 having 120a, and its opening 120a is positioned while holding a step between the bottom part 111 and the body part 112 in the bottle 110. In this embodiment, the peripheral wall 123 further includes an inclined portion 123a to which the inclined portion 111b of the bottle bottom portion 110 is fixed via the adhesive B, and an internal fit with the cylindrical portion 111a of the bottle bottom portion 110 connected to the inclined portion 123a. The cylindrical portion 123a is joined, but may be simply press-fitted.

  Here, FIG. 3 is a sectional view further enlarging the main part of FIG. As shown in FIGS. 3 (a) and 3 (b), the base cup 120 has at least one through-hole 1 communicating with the inside and outside at the end edge 122 connecting the bottom wall 121 and the peripheral wall 123. On the ground contact surface 121f of the bottom wall 121, a groove 2 connected to the through hole 1 and extending toward the bottle axis O is formed. Further, the film sheet 130 has a covering end 130e that covers the through hole 1 formed in the bottom wall 121 of the base cup 120, and the covering end 130e and the remainder of the groove 2 in the bottom wall 121 of the base cup 120. An opening 3 is formed to allow the inside and outside of the base cup 120 to pass therethrough.

  In such a configuration, first, the through-hole 1 provided in the bottom wall 121 of the base cup 120 is covered with the covering end 130e of the film sheet 130, so that light does not directly hit the bottom 111 of the bottle body 110. . Moreover, in such a configuration, the opening that allows the inside and outside of the base cup 120 to pass through the covering end 130e of the film sheet 130 that covers the bottle body 110 and the base cup 120 and the groove 2 formed in the bottom wall 121 of the base cup 120. 3 is formed, the air permeability (drainage) between the bottle body 110 and the base cup 120 can also be secured. Therefore, according to the present embodiment container 100, the bottom 111 of the bottle main body 110 is not directly exposed to light, and air permeability (drainage) between the base cup 120 can be ensured. In short, it has an excellent effect as a container filled with contents that are easily affected by light.

  The through hole 1 may be an area of only the bottom wall 1, but an area including the lowermost position of the base cup 120, that is, an edge 122 where moisture flowing down from the peripheral wall 123 accumulates as in the present embodiment. If the through-hole 1 is provided in this, efficient drainage can be expected. In addition, more efficient drainage can be expected if the through-hole 1 is formed at a position aligned almost directly below the end 111c of the bottle body 110 as in this embodiment. Further, the groove 2 is not limited to one having a narrower width than the diameter of the through-hole 1, and as shown in FIG. The hole 1 may be formed. Furthermore, the base cup 120 may have a dome-shaped portion in which the bottom wall 121 protrudes toward the bottle axis O toward the inside of the bottle. In this case, drainage in the base cup 120 is improved.

  4 (a) and 4 (b) are a perspective view and a cross-sectional view of the relevant part showing the third embodiment of the present invention from the bottom wall 121 of the base cup 120, respectively. In this embodiment, the same parts as those in FIGS.

  In the base cup 120 according to this embodiment, as shown in FIG. 4, the end of a cylindrical leg 124 standing in a ring is used as the ground contact surface 120e, and the cylindrical leg 124 is integrally connected to the bottom walls 121 and 126. As shown in FIG. 4, at least one through hole 1 is formed in the bottom wall 121 outside the cylindrical leg 124, and a groove 2 connected to the through hole 1 is formed. A cutout portion 124c obtained by cutting a part of the portion 124 is formed so as to be connected to the groove 2.

  According to this configuration, even if the base cup is provided with the cylindrical leg 124 on the bottom wall 121 and the end 120e thereof is the ground contact surface, the covering end 130e of the film sheet 130 covers the through hole 1 of the bottom wall 121. When concealed, the film sheet covering end 130e and the groove 2 form an opening 3 through which the inside and outside of the base cup 120 pass, and the same effect as the first embodiment described in FIGS. It is done. In this embodiment, the covering end 130e of the film sheet 130 covers the through hole 1. The covering end 130e is a connection formed between the bottom wall 121 and the cylindrical leg portion 124. It can be extended to the periphery 125.

  Further, in this embodiment, a part of the cylindrical leg portion 124 is cut out to form the gap C, so that the cylindrical leg portion 124 does not interfere with ventilation (drainage), and efficient ventilation ( (Drainage) can be expected. Furthermore, in this case, the outer surface 126f of the bottom wall 126 provided continuously with the upper portion of the cylindrical leg 124 may be flush with the outer surface 121f of the bottom wall 121 outside the cylindrical leg 124. If the outer surface 126f of the bottom wall 126 connected to the upper portion of the cylindrical leg 124 is aligned with the groove bottom of the groove 2 as in this embodiment, more efficient ventilation (drainage) can be expected. .

  In this embodiment, the lateral width C1 of the cutout portion 124c formed by cutting a part of the cylindrical leg portion 124 is narrower than the lateral width C2 of the groove 2 formed in the outer surface 121f of the bottom wall 121. However, such a configuration is intended to focus on the strength of the cylindrical leg 124, and the magnitude relationship between the lateral widths C1 and C2 can be appropriately changed as long as the strength normally used can be secured.

  Further, the base cup 120 in this embodiment is formed by integrally molding the bottom wall 126 and the bottom wall 121 together with the cylindrical leg portion 124, but considering the ease of die removal when the base cup 120 is molded, The wall 126 or an integrally molded product of the bottom wall 126 and the cylindrical leg (leg) 124 may be assembled as a separate body. When assembling only the bottom wall 126 as a separate body, specifically, the base cup 120 has an opening in the periphery including the cylindrical leg 124, that is, the outside from the cylindrical leg 124 of the bottom wall 121. A part of the bottom wall 121, a part of the cylindrical leg 124 cut out, and the entire inside of the cylindrical leg 124 are opened, and provided separately from the inside of the base cup 120. The bottom wall 126 is assembled so that only a part of the bottom wall 121 side is open. Even with such a configuration, as a result, the opening portion that is not covered by the bottom wall 126 forms the through hole 1 formed outside the cylindrical leg portion 124 of the bottom wall 121, and the outer surface 126f of the bottom wall 126 is also formed. Forms a groove 2 connected to the through-hole 1.

  FIGS. 5A to 5C are an enlarged cross-sectional view of a main part of a fourth embodiment of the present invention, a front view in the D1 direction, and a front view in the D2 direction, respectively. Also in this embodiment, the same parts as those in FIGS.

  As shown in FIG. 5, in this embodiment, a cutout portion 124 c obtained by cutting off a part of the cylindrical leg portion 124 is formed so as to be continuous with the groove 2 connected to the through hole 1, as in the third embodiment described above. However, in particular, in the present embodiment, the bottom wall 127 connected to the upper portion of the cylindrical leg portion 124 has a raised portion 127p that protrudes toward the bottle axis O toward the inside of the bottle. According to this configuration, since the surface of the raised portion 127p is inclined toward the through hole 1, the water dropped on the bottle axis O side can be efficiently flowed to the through hole 1, so that more efficient drainage can be performed. I can expect.

  In the third and fourth embodiments, the groove 2 is formed so that the cutout portion 124c from which the cylindrical leg portion 124 is cut is continuous with the groove 2, but this cylindrical leg portion 124 is cut off. Without forming the groove on the outer surface of the cylindrical leg 124, the groove connected to the through hole 1 through the groove 2 formed on the bottom wall 121 from the end 120e of the cylindrical leg 124 can be formed. Good. Further, the leg portion 124 is not limited to the cylindrical shape that is annularly suspended from the bottom wall 121 as in the third and fourth embodiments, but a plurality of legs that are suspended from the bottom wall 121 by intermittently concentric circles, etc. It may be.

  What has been described above is merely illustrative of preferred embodiments of the present invention, and those skilled in the art can make various modifications within the scope of the claims. For example, the covering is not limited to a sheet material such as a film sheet but may be a label such as a shrink label. Further, the material used for the bottle body 110 and the base cup 120 is not limited, but the base cup 120 and the film sheet 130 have a light shielding property capable of blocking sunlight and light of a specific wavelength. If it is molded from a synthetic resin containing the material, the light shielding effect is remarkably improved and the quality assurance period of the contents can be greatly extended. Further, the configurations of the first to fourth embodiments can be variously combined depending on the application.
