DESCRIPTION OF EMBODIMENTS

As shown in FIG. 1, a bottle container 1 includes an inner container 2, an outer container 3 which receives the inner container 2 therein, and a heat-shrinkable film 4 which integrates and wraps the inner container 2 and the outer container 3. In FIG. 1, only the inner container 2 is shown in a side view, and the outer container 3 and the heat-shrinkable film 4 are shown in a cross-sectional view. As shown in FIG. 2A and FIG. 2B, the inner container 2 includes an inner container body 2a and a cap 2b, and the cap 2b is located at an upper portion of the inner container body 2a. The inner container body 2a includes a cylindrical trunk 5 and a bottom 6 which forms a lower end part of the trunk 5. As shown in FIG. 3, an annular opening portion 7 is located at the upper side of the trunk 5, and a shoulder 8 having a tapered shape is formed between the trunk 5 and the opening portion 7. The inner container body 2a is formed of an easily-breakable material (bottle) and has a light-transmitting property of being transparent or semitransparent.


As shown in FIG. 3, the cap 2b which covers the opening portion 7 of the inner container body 2a includes a sealing plug 9, a sealing portion 10, and a cap portion 11. The sealing plug 9 is formed of an elastic body so as to block the opening portion 7 of the inner container body 2a, the surrounding of the opening portion 7 plugged with the sealing plug 9 is fixed by the sealing portion 10 which is made of metal, and the cap portion 11 is provided so as to cover the upper surfaces of the sealing plug 9 and the sealing portion 10.


The inner container 2, which includes the cap 2b and the inner container body 2a having the opening portion 7 blocked by the cap 2b, is a medical vial 12 in which the opening portion 7 of the inner container body 2a is plugged with the cap 2b after a drug solution is injected into the inner container body 2a.


As shown in FIG. 4A, FIG. 4B, FIG. 5A, and FIG. 5B, the outer container 3 is a transparent or semitransparent cylindrical cushioning container 16 which includes a bottom 13, a side wall 14, and an opening 15, and the vial 12 is received therein. The cushioning container 16 has a light-transmitting property of being transparent or semitransparent and is formed from a resin.


As shown in FIG. 5A, the bottom 13 of the cushioning container 16 includes a center portion 13a and an outer peripheral portion 13b, and the center portion 13a is formed with a thickness T1 smaller than the thickness T2 of the outer peripheral portion 13b (T1<T2), whereby a space 13c is formed.


As shown in FIG. 5A and FIG. 5B, the side wall 14 includes projection portions 14b which project inward and extends from a lower portion of an inner wall 14a toward the opening 15, that is, in an up-down direction in the drawing (the height direction of the side wall 14). The side wall 14 is formed in a cylindrical shape. As shown in FIG. 5A, the side wall 14 is formed with a thickness T3 smaller than the thickness T2 of the outer peripheral portion 13b of the bottom 13 (T3<T2).


Each projection portion 14b extends from the bottom 13 toward the opening 15 to the vicinity of the opening 15 without reaching the opening 15. Specifically, each projection portion 14b has a transverse cross-section having a quadrilateral shape with four right angles which is a rectangle or a square, and has outer opposed surfaces 17 opposed to each other (FIG. 4A), a flat connection surface 18 connecting both outer opposed surfaces 17, and a step 19 projecting toward the inner side of the cushioning container 16 at the upper end of the projection portion 14b. The outer opposed surfaces 17 are formed such that the interval therebetween is uniform along the longitudinal direction.


In addition, as shown in FIG. 4A, the projection portions 14b are formed on the inner wall 14a of the cushioning container 16, which is formed in a circular shape as seen from above, discontinuously in the circumferential direction. Specifically, the projection portions 14b are formed on the inner wall 14a of the cushioning container 16 at equal angular intervals around a center portion of the cushioning container 16 as seen from a plane (FIG. 4A illustrates three projection portions 14b formed at intervals of 120 degrees).


Next, a method of mounting the vial 12 to the cushioning container 16 will be described. FIG. 6 and FIG. 7A show an example of mounting the vial 12 into which a drug solution has been injected, to the cushioning container 16. First, with the bottom 6 of the vial 12 being directed downward, the vial 12 is moved toward the opening 15 of the cushioning container 16 that is placed such that the opening 15 faces upward (FIG. 6). Then, the bottom 6 of the vial 12 is inserted into the opening 15 of the cushioning container 16 and butted against the bottom 13 of the cushioning container 16 to obtain a state where the cushioning container 16 is mounted to the vial 12 (FIG. 7A).


In this state, as shown in FIG. 7A, the cushioning container 16 extends from the bottom 6 of the vial 12 over the trunk 5, and the opening 15 of the cushioning container 16 reaches the shoulder 8 of the vial 12 or the vicinity of the shoulder 8. Here, as shown in a partially enlarged view of FIG. 7B, a gap 20 is formed between the trunk 5 of the vial 12 which is located within the cushioning container 16 and the inner wall 14a of the cushioning container 16 which is opposed to the trunk 5. Specifically, the gap 20 is formed so as to surround the trunk 5 of the vial 12 and is also formed between each projection portion 14b of the cushioning container 16 and the trunk 5 of the vial 12. Similarly, as shown in FIG. 7A, at the bottom 13 of the cushioning container 16, the space 13c is formed such that the center portion 13a of the bottom 13 is not brought into contact with the bottom 6 of the vial 12.


In FIG. 8A, in order to integrate the vial 12 and the cushioning container 16 of FIG. 7A, the vial 12 and the cushioning container 16 are covered with the heat-shrinkable film 4, and the side wall 14 of the cushioning container 16 and at least a part of the shoulder 8 of the vial 12 are covered with the heat-shrinkable film 4. Specifically, the heat-shrinkable film 4 extends from the sealing portion 10 of the vial 12 through the shoulder 8 of the vial 12 to the side wall 14 of the cushioning container 16 to wrap a range from the sealing portion of the vial 12 to the side surface of the cushioning container 16. Here, the thickness of the heat-shrinkable film 4 is exaggeratingly drawn for the convenience of explanation, but is actually very small as compared to the thicknesses of the vial 12 and the cushioning container 16.



FIG. 8B is a partially enlarged view of FIG. 8A. As shown in FIG. 8B, a shoulder space 21 is formed between the shoulder 8 of the vial 12 which is located within the cushioning container 16 and the heat-shrinkable film 4 which is opposed to the shoulder 8. That is, while the gap 20 is ensured, the shoulder space 21 is formed so as to surround a connection portion between the trunk 5 and the shoulder 8 of the vial 12.


When the vial 12 to which the cushioning container 16 has been mounted is wrapped with the heat-shrinkable film 4 as described above, the bottle container 1 is completed. In taking the drug solution, which is injected in the vial 12, out from the bottle container 1, the cap portion 11 of the vial 12 is removed, the tip of the needle of a syringe or the like is stuck into the sealing plug 9 to penetrate the sealing plug 9, and the drug solution is extracted from the inside of the vial 12, whereby it is possible to use the drug solution within the bottle container 1.


As described above, in the bottle container 1, the cushioning container 16 is mounted so as to extend along the trunk 5 and the bottom 6 of the vial 12 as shown in FIG. 8A, and the vial 12 and the cushioning container 16 are integrated by means of the heat-shrinkable film 4, whereby impact on the trunk or the bottom 6 of the vial 12, etc. can be absorbed by the cushioning container 16 to prevent breakage of the vial 12.


Specifically, as shown in FIG. 7A, the cushioning container 16 extends from the bottom 6 of the vial 12 over the trunk 5, and the opening 15 of the cushioning container 16 reaches the shoulder 8 of the vial 12 or the vicinity of the shoulder 8. Thus, for example, even if the bottle container 1 is slammed at the bottom 13 of the cushioning container 16 against a floor surface 22 as shown in FIG. 9A, the impact can be absorbed by the bottom 13 of the cushioning container 16. Similarly, even if the bottle container 1 placed on the floor surface 22 tips over as shown in FIG. 9B, the impact can be absorbed by the side wall 14 of the cushioning container 16 (even if the bottle container 1 is slammed at the side wall 14 of the cushioning container 16 due to not only tipping over but also drop of the bottle container 1, the impact can be absorbed).


That is, since, at the center portion 13a of the bottom 13 of the cushioning container 16, the space 13c is formed such that the center portion 13a of the bottom 13 is not brought into contact with the bottom 6 of the vial 12 as shown in FIG. 8A, even if the bottom 13 of the cushioning container 16 is slammed against the floor surface 22, the impact is prevented from being transmitted from the center portion 13a of the cushioning container 16 directly to the bottom 6 of the vial 12, and the impact on the vial 12 can be cushioned.


Similarly, since the gap 20 is formed between the trunk 5 of the vial 12 and the inner wall 14a of the cushioning container 16 which is opposed to the trunk 5 as shown in FIG. 8B, even if the placed bottle container 1 tips over or the bottle container 1 drops with the side wall 14 of the cushioning container 16 being at the lower side, the gap 20 serves as an air cushion in a sense and can cushion the impact transmitted from the inner wall 14a of the cushioning container 16 to the vial 12. In addition, since the gap 20 is formed so as to surround the trunk 5 of the vial 12, even if the bottle container 1 tips over in any direction or drops in any direction with the side wall 14 of the cushioning container 16 being at the lower side, the impact can be cushioned.


In wrapping with the heat-shrinkable film 4, due to shrinkage of the heat-shrinkable film 4, an external force is applied to the side wall 14 of the cushioning container 16 and acts so as to narrow the gap 20 between the side wall 14 and the trunk 5 of the vial 12 depending on the material of the cushioning container 16 (when the material of the cushioning container 16 is soft). However, contact between the inner wall 14a of the cushioning container 16 and the trunk 5 of the vial 12 is suppressed by each projection portion 14b of the cushioning container 16. Each projection portion 14b serves as a gap formation assist portion which assists in forming the gap 20, thereby enhancing the air cushion effect of the gap 20. In addition, in addition to the time when the external force is applied by the heat-shrinkable film 4, also when another external force such as external impact is applied, contact between the inner wall 14 of the cushioning container 16 and the trunk 5 of the vial 12 is similarly suppressed. Even when the material of the cushioning container 16 is hard, also if the gap between the side wall 14 and the trunk 5 of the vial 12 is narrowed by some chance, contact between the inner wall 14 of the cushioning container 16 and the trunk of the vial 12 can be suppressed by the projection portions 14b. Furthermore, even if the gap 20 is not narrowed, each projection portion 14b servers as a rib to increase the rigidity of the cushioning container 16, whereby impact on the vial 12 can be absorbed.


Since each projection portion 14b extends to the vicinity of the opening 15 without reaching the opening 15 of the cushioning container 16 as shown in FIG. 5A and FIG. 5B, even if the placed bottle container 1 tips over as shown in FIG. 9B, in particular, even if the bottle container 1 tips over such that the outer wall side thereof corresponding to the inner wall 14a of the cushioning container 16 on which the projection portions 14b are formed is slammed against the floor surface 22 (or even if the bottle container 1 drops so), a large space can be ensured, as shown in FIG. 8B, as the gap 20 around the opening 15 of the cushioning container 16 on which a large impact force acts, and the air cushion effect can be achieved although the projection portions 14b are provided.


Since the projection portions 14b are formed so as to extend from the bottom 13 of the cushioning container 16 toward the opening 15 as shown in FIG. 5A and FIG. 5B, contact between the inner wall 14a of the cushioning container 16 and the trunk 5 of the vial 12 can be suppressed at least in the vicinity of a region from the bottom 13 of the cushioning container 16 to the opening 13 in which each projection portion 14b is formed.


Since the connection surface 18 connecting the outer opposed surfaces 17 of each projection portion 14b is a flat surface as shown in FIG. 4A to FIG. 5B, contact with the tubular cushioning container 16 can be effectively suppressed. In addition, since the interval between the outer opposed surfaces 17 is uniform, the gap 20 can be formed substantially uniformly in the up-down direction of the vial 12 and the cushioning container 16, so that a large space can be ensured as the gap 20 between the vicinity of the shoulder 8 of the vial 12 and the opening 15 of the cushioning container 16 by the step 19 of each projection portion 14b.


Since the projection portions 14b are formed on the inner wall 14a of the cushioning container 16, which is formed in a circular shape as seen from above, discontinuously in the circumferential direction as shown in FIG. 4A, the projection portions 14b can assist in forming the gap 20 along the circumferential direction of the cushioning container 16. Specifically, since the projection portions 14b are formed at equal angular intervals in the circumferential direction around the center portion of the cushioning container 16 as seen from a plane (FIG. 4A) (in FIG. 4A, the three projection portions 14b are formed), the projection portions 14b can assist in forming the gap 20 uniformly in the circumferential direction of the cushioning container 16, thereby enhancing cushioning performance in the circumferential direction of the cushioning container 16.


Since the side wall 14 including the projection portions 14b is formed with the thickness T3 smaller than the thickness T2 of the outer peripheral portion 13b of the bottom 13 as shown in FIG. 5A, the center of gravity of the cushioning container 16 becomes low, and the cushioning container 16 becomes stable during time of being placed.


In integrating the cushioning container 16 and the vial 12 by means of the heat-shrinkable film 4, the shoulder space 21 is formed between the shoulder 8 of the vial 12 and the heat-shrinkable film 4 which is opposed to the shoulder 8 as shown in FIG. 8B. Thus, if the placed bottle container 1 tips over as shown in FIG. 9B (or if the bottle container 1 drops so), the shoulder space 21 can protect the surrounding of the opening 15 of the cushioning container 16 on which a large impact force acts. The shoulder space 21, together with the gap 20, enhances the air cushion effect.


Since the heat-shrinkable film 4 wraps the range from the sealing portion 10 of the vial 12 through the shoulder 8 to the side wall 14 of the cushioning container 16, and the cap portion 11 is not covered with the heat-shrinkable film 4 as shown in FIG. 8A, it is possible to use the drug solution within the vial 12 without peeling off the heat-shrinkable film 4. Specifically, the exposed cap portion 11 is removed from the vial 12, and the drug solution can be extracted through the sealing plug 9 by using a syringe or the like. Therefore, even during use of the bottle container 1 in which the risk of drop of the bottle container 1 increases, the bottle container 1 can prevent breakage of the vial 12, since the cushioning container 16 and the vial 12 are integrated.


As shown in FIG. 1 and FIG. 3, the portion of the vial 12 that is not covered with the cushioning container 16 has a tapered shape, the opening portion 7 of the vial 12 is covered with the cap 2b, and the portion of the vial 12 that is not covered with the cushioning container 16 and the cap 2b has a constricted shape. Thus, even if the bottle container 1 drops, there is a low possibility that the tapered-shaped portion of the vial 12 that is not covered with the cushioning container 16 is slammed directly against the floor surface, and bottle breakage can be efficiently prevented without covering the entire surface of the vial 12.


The bottle container 1 having a bottle breakage-preventing function has been described above. Next, a modification of the shoulder 8 of the inner container 2 shown in FIG. 10 will be described. The configuration other than the shoulder 8 is the same as the configuration of the above-described vial 12, and the main difference is the shape of the shoulder 8. FIG. 10 is a cross-sectional view showing Modification 1 of a shoulder 8a of the inner container 2. The shoulder 8 having a constricted shape is formed between the trunk 5 and the opening portion 7. Thus, the portion of the vial 12 that is not covered with the cushioning container 16 or the cap 2b is formed in a recessed shape in a sense, and hence it is possible to reduce a possibility that impact is applied directly to the constricted-shaped portion of the vial 12 that is not covered with the cushioning container 16.


In the above description, each projection portion 14b of the cushioning container 16 extends from the lower portion (bottom 13) of the side wall 14 toward the opening 15. However, each projection portion 14b may be configured to extend from a middle portion of the side wall 14 toward the opening 15 as shown in FIG. 11. In addition, as shown in FIG. 12, no projection portion may be formed in the bottle container 1. Even when no projection portion is formed, the gap 20 and space 13c can suppress transmission of external force to the vial 12.


In the above description, the heat-shrinkable film 4 wraps the range from the sealing portion 10 of the vial 12 to the side surface of the cushioning container 16. However, the heat-shrinkable film 4 may wrap a range from below the sealing portion 10 of the vial 12 through the shoulder 8 to the side surface of the cushioning container 16 as shown in FIG. 13, or may wrap the connection portion where the shoulder 8 of the vial 12 and the trunk 5 are connected to each other, and the surrounding of the connection portion as shown in FIG. 14. When the connection portion and its surrounding are wrapped, it is possible to reduce the quantity of the heat-shrinkable film 4 to be used.


As shown in FIG. 15, an adhesive portion 4a may be formed on the back surface of the heat-shrinkable film 4. In a state where the vial 12 and the cushioning container 16 adhere to the heat-shrinkable film 4 by means of the adhesive portion 4a, the vial 12 and the cushioning container 16 are wrapped. Thus, the gap 20 is sealed, and it is possible to enhance the cushion effect of the gap 20. In addition, as shown in FIG. 16, a printed portion 4b may be provided to the heat-shrinkable film 4.


Although the embodiments of The invention have been described above, The invention is not limited to the specific description thereof, and the illustrated configurations and the like can be combined as appropriate within a range where there is no technical contradiction, to practice The invention, or a certain element or process can be substituted with a known form to practice The invention.
