Description

  The present invention relates to an air injection type container cover. When injecting air, the container cover of the present invention expands in accordance with the outer shape of the container, so that one container can be used for various baby bottles and PET bottles having different outer shapes and dimensions (heights). The cover can be held and covered in close contact with the side surface of the container in response to various changes in the outer shape, and the container cover can be handled integrally with the container.

As an air-injection type (air type) container cover, an air chamber is formed by connecting the outer surface of the cover body and the lining of the non-breathable outer surface and the outer edge of the non-breathable lining together with a plurality of close contact parts. A heat insulating cover is known in which a pair of couplers such as fasteners are attached to both sides of a cover body (Patent Document 1). This thermal insulation cover winds the cover body around a container such as a bottle or can, and then joins both sides with a pair of fasteners such as fasteners, and then injects air from the air inlet to expand the communication air chamber. Or, it can be used by inflating the air chamber before attaching it to the container, so that the liquid in the container can be kept warm and damage due to impact can be prevented, and after use it can be folded down by removing the air and removing it from the container It is supposed to be possible.
However, although Patent Document 1 describes the heat retaining effect, the buffering effect, and the ease of handling, there is no description about the adhesion between the container and the cover. Furthermore, in the embodiment specifically shown in the accompanying drawings of the above-mentioned patent document 1, the cover body itself is contained in the bottle to be accommodated as the outer diameter continuously narrows from the shoulder to the neck. The corresponding part is also deformed so that the corresponding part becomes narrower. That is, the shape of the cover body that covers it is changed in accordance with the change in the outer shape of the container to be stored, and the cylindrical cover having the same inner diameter from one opening to the other is specific. There is no description. Also, there is no disclosure of means for applying one container cover to a plurality of containers having different heights. Furthermore, there is no description of means for applying one container cover to a plurality of containers having different heights and outer shapes.

Japanese Utility Model Publication No. 61-5772

Air-injection type (air type) container cover has a function to maintain the temperature of the beverage in the container (warm / cold function) and a buffer function to prevent breakage when a fragile container (for example, a glass container) is dropped. Is mainly sought after. However, in an air-injection (air-type) container cover such as a baby bottle or a PET bottle, when the container is used for drinking, the container is not removed from the cover but can be used for drinking with the cover attached to the container. It is extremely convenient if possible. Thus, in order to use for drinking with the cover attached to the container, it is necessary that the container and the cover are in close contact with each other so that the container and the cover can be handled integrally. . In particular, in the case of a container used by an infant, such as a baby bottle, it is likely that the infant will grab only the cover and use it without grasping the baby bottle, so it is dangerous if the container comes off the cover. In addition, since there are various types of baby bottles in which the height and outer diameter of the bottle are changed along the growth stage of the infants, one cover can be used for these various types. Convenient.
Therefore, the object of the present invention is to guarantee the integrity of the container while maintaining the temperature maintenance effect (heat insulation / cooling effect), buffer effect, and ease of handling as an air injection type (air type) container cover. An object of the present invention is to provide a cover that can accommodate various containers having different adhesion such as height and height.

The above-mentioned problem is an air-injection-type container cover having a cylindrical wall portion composed of an outer sheet made of non-breathable soft material and an inner sheet made of non-breathable soft material according to the present invention,
The entire inside of the cylindrical wall portion is composed of a whole air chamber formed by airtightly closing the peripheral edge of the outer sheet and the inner sheet,
In the flat state where the cylindrical wall portion is not injecting air from the air inlet / outlet means to the entire air chamber, the inner diameter and the outer diameter are each constant in the axial direction,
The cylindrical wall portion is substantially cylindrical in an expanded state in which air is injected from the air inlet / outlet means into the entire air chamber,
The entire air chamber is divided into a plurality of ventilation small chambers capable of air flow with each other by a divided joint portion that joins the outer sheet and the inner sheet, and
This can be solved by the container cover characterized in that it includes at least one folding joint extending in the circumferential direction of the cylindrical wall.

In a preferred embodiment of the container cover according to the present invention, the entire air chamber consists of one air chamber as a whole, or by a laterally closed joint band extending continuously around the circumference of the cylindrical wall portion. It consists of two or three sealed air chambers that are separated and do not allow air to flow between them.
In a further preferred aspect of the container cover according to the present invention, the split joint portion is continuous from one end edge or end region to another end edge or end region in a direction parallel to the axial direction of the cylindrical wall portion. Alternatively, a longitudinally divided joining band that extends discontinuously, a transversely divided joining band that extends continuously or discontinuously throughout the circumferential direction of the cylindrical wall part, or an axis of the cylindrical wall part Arranged on the straight line extending from one end edge to the other end in the direction parallel to the direction with the same interval, and arranged on the straight line extending in the circumferential direction of the cylindrical wall portion with the same interval. It is a dotted or cross-shaped joint.

In a further preferred aspect of the container cover according to the present invention, it extends continuously or discontinuously from one edge or end region to the other edge or end region in a direction parallel to the axial direction of the cylindrical wall. The entire air chamber is 5 to 16 by a plurality of longitudinally divided joining bands and one ring-closing joining band that continuously extends from one end edge to the other end in a direction parallel to the axial direction of the cylindrical wall portion. The vent chamber is divided at equal intervals in the circumferential direction,
Each ventilation chamber is capable of air flow between each other,
Each of the longitudinally divided joining bands and the ring-closing joining bands has folding joining bands that intersect in the orthogonal direction and extend discontinuously in the circumferential direction of the cylindrical wall portion.

In a further preferred aspect of the container cover according to the present invention, air can be circulated between the whole air chamber or air to the opening end opposite to the opening end having the folding joining band. Is further provided with a buffer protection bottom portion formed as one air chamber in the circumferential direction of the cylindrical wall portion.
In a further preferred aspect of the container cover according to the present invention, a grip handle portion and / or a suspension strap portion are further provided on the outer surface of the cylindrical wall portion.
In a further preferred aspect of the container cover according to the present invention, a lid is further provided on at least one of the open ends.
In a further preferred aspect of the container cover according to the present invention, the container cover has a heat storage liner that is fixedly provided inside or detachably provided inside the container cover.

  The present invention also relates to a heat storage liner that can be used in contact with the inside of the container cover.

  In the present specification, the upper and lower positional relationship (for example, “upper” or “lower”) in the container cover (or container) according to the present invention is the general relationship of the container when the container cover of the present invention is attached to the container. It is shown for convenience of explanation along the vertical relationship, and does not limit the positional relationship in other states (for example, the state at the time of storage or use). Here, the general vertical relationship of a container means that an end portion having a drinking mouth of a beverage container is an upper part.

The container cover of the present invention is an air-injection type (air type) container cover, when the temperature maintenance function (warm / cold function) of the beverage in the container and a fragile container (for example, a glass container) are dropped. Has a buffer function to prevent breakage. In addition, the container mounting operation and the container detaching operation are performed by injecting air from a small number (especially one) of air inlet / outlet means to inflate the container cover to closely contact the container, or discharge the air to discharge the container. By simply flattening the cover and releasing the unity with the container, there is no need for a release operation such as a fastener or an opening / closing operation of the lid, and handling is extremely easy. Furthermore, the container cover of the present invention can be brought into close contact with the side wall of the container by injecting air, and it is substantially impossible to remove the container cover from the container in the tightly infused air injection state. Therefore, the container and the container cover can be used integrally.
Further, one container cover can be used by being applied to various containers having different heights and outer shapes.

  Furthermore, store the product with the cap attached, such as a baby bottle, and remove the cap for drinking, with the container cover attached and the same cap as the non-attached state of the container cover. In addition, the container cover of the present invention can be used without removing it from the baby bottle in either the cap-mounted state or the cap-removed state.

Hereinafter, typical embodiments of the container cover according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic perspective view showing a state in which a baby bottle 2 is being inserted into a flat container cover 1 according to the present invention. FIG. It is a typical perspective view which shows the state which inject | poured air and made the container cover 1 closely_contact | adhere to the baby bottle 1, and was integrated. FIG. 3 is a schematic perspective view of the container cover 1 in an expanded state in which air is injected without charging the baby bottle 2.

  As shown in FIG. 1, when the container cover 1 according to the present invention is used, the baby bottle is placed in the inner space 14 of the flat cylindrical wall portion 11 in which air is not injected into the container cover 1 from the air inlet / outlet means 15. 2 is charged. Alternatively, the container bottle 1 according to the present invention can be covered with the baby bottle 2 upright on the desk from above. The baby bottle 2 is provided with a nipple 21 and a nipple attachment ring 22 at its tip, and a cap 25 is attached from above. The container cover 1 according to the present invention needs to have an inner inner diameter larger than an outer outer diameter of the container to be mounted in a flat state where air is not injected. Further, as described later, it is necessary to have an inner diameter that allows the inner wall surface of the container cover 1 according to the present invention to be in close contact with the outer wall surface of the container by injecting air. In addition, as shown in FIG. 1, the cylindrical wall part 11 of the flat state which is not inject | pouring air has the internal diameter and the outer diameter, respectively about the axial direction (direction of arrow A) of the cylindrical wall part 11 substantially. It is uniform. The container cover 1 according to the present invention can be formed into a flat sheet as a whole by bringing the inner wall surfaces into contact with each other in a flat state where air is not injected.

  The container cover 1 according to the present invention includes an outer sheet 12 made of a non-breathable soft material (for example, a synthetic resin) and an inner sheet 13 made of a non-breathable soft material, and an upper edge 12A and an inner sheet of the outer sheet 12. The upper end edge 13A of 13 is formed with an upper end edge 11A that is hermetically closed by joining them. On the other hand, at the lower edge 12B of the outer sheet 12 and the lower edge 13B of the inner sheet 13, an airtight lower edge 11B is formed by folding one sheet. Therefore, the inside of the outer sheet 12 and the inner sheet 13 is hermetically closed by the upper edge 11A and the lower edge 11B. Note that the upper edge 11A is formed by folding one sheet and the lower edge 11B is formed by joining the outer sheet 12 and the inner sheet 13, or the upper edge 11A and the lower edge. 11B may be formed by joining the outer sheet 12 and the inner sheet 13, and both the upper edge 11A and the lower edge 11B may be formed by folding the sheet (tubular sheet). it can.

  In the present invention, the joining and the joining described later are both performed using any known method, for example, a high-frequency fusion method, a hot plate fusion method, a hot air fusion method, or an ultrasonic fusion method. Can do. The high-frequency fusion method is, for example, that a part of a synthetic resin sheet and a part of a synthetic resin sheet to be bonded to each other are overlapped, and this overlapped part is placed between two electrodes (one electrode is a weld bar). While applying a weld bar to the overlapped portion, a potential difference that oscillates at a high frequency is applied to the electrode, and the overlap is applied by the molecular frictional heat of the synthetic resin sheet generated at the applied portion. Of the portions, the portion pressed by the weld bar is heat-sealed. In the hot air fusion method, hot air is blown between the joint surfaces (overlapping parts) of the synthetic resin sheet through the nozzle tip selected according to the fusion specifications of the joined body by electric control of the heater, and the surface of the synthetic resin sheet is blown. This is a method in which mutual melting is performed instantaneously, and immediately after that, bonding is performed by pressure bonding. Further, the hot plate fusion method is a method in which a synthetic resin sheet adhesive portion is pressure-bonded using a heated mold (trowel) built in a heater above the melting temperature of the synthetic resin sheet, and continuously sealed. . Furthermore, the ultrasonic fusion method amplifies the amplitude of ultrasonic energy generated from an ultrasonic transducer through the tip of a tool horn, and projects this onto the synthetic resin sheet to be fused, thereby separating the boundary between both synthetic resin sheets. In this method, the frictional heat generated on the surface is used for instantaneous fusion.

  The container cover 1 shown in FIG. 1 has, on the side surface of the cylindrical wall portion 11, one closed joint band 31 that extends in the axial direction (the direction of arrow A) of the cylindrical wall portion 11 and seven longitudinally divided joint bands 32. including. The ring-closing joining band 31 air-tightly joins both ends in the axial direction of the outer sheet 12 and the inner sheet 13 in a band-like manner when the wall portion composed of the outer sheet 12 and the inner sheet 13 is closed to form a cylindrical body. It is a joining band formed in this way. Therefore, as shown in FIG. 1, the ring-closing joining band 31 extends from one upper end edge 11 </ b> A to the other lower end edge 11 </ b> B in a direction parallel to the axial direction (direction of arrow A) of the cylindrical wall portion 11. It extends continuously (ie without disconnection). Thus, the outer sheet 12 and the inner sheet 13 are hermetically closed by the upper edge 11 </ b> A, the lower edge 11 </ b> B, and the ring-closing joining band 31, and are closed inside the outer sheet 12 and the inner sheet 13. Two overall air chambers are formed.

  The container cover 1 shown in FIG. 1 includes seven longitudinally divided joining bands 32 in addition to the above-described ring-closing joining band 31, and a total of eight joining bands 31, 32 are arranged in the circumferential direction (direction of arrow B). They are installed parallel to each other at approximately equal intervals. These eight joining bands 31 and 32 divide one whole air chamber into eight ventilation chambers in the vertical direction. In FIG. 1, it shows as the 1st division | segmentation joining band 32a provided in the front side surface, and the 2nd division | segmentation joining band 32b. These divided bonding bands 32 are also bonding bands formed by airtightly bonding the outer sheet 12 and the inner sheet 13 in a band shape. Each split joining band 32 extends from one upper end region 11T of the cylindrical wall 11 to the other of the cylindrical wall 11 in a direction parallel to the axial direction of the cylindrical wall 11 (direction of arrow A). This is a longitudinally divided joining band extending continuously (that is, without disconnection) to the lower end region 11S. The upper end portion 32A of each divided joining band 32 does not reach the upper end edge 11A of the cylindrical wall portion 11, and the lower end portion 32B of each divided joining band 32 is the lower end edge 11B of the tubular wall portion 11. Therefore, the inner sides of the outer sheet 12 and the inner sheet 13 are not joined at the upper edge 11A and the lower edge 32B, and air flows therethrough. Moreover, it is preferable that each upper end part and each lower end part of each division | segmentation joining band 32 exist in the substantially same position regarding the circumferential direction (direction of arrow B), as shown in FIG.

  In order to manufacture the container cover 1 shown in FIG. 1, for example, one sheet of non-breathable soft material is cut into a rectangle and bent at the center to form a two-layer rectangular sheet having a half size. One of the two layers is the outer sheet 12 of the container cover 1 shown in FIG. 1, the other is the inner sheet 13, and the folding side is the lower edge 11B of the container cover 1 shown in FIG. Thereafter, since the two sheets are joined on the side opposite to the folded side, this joined side becomes the upper edge 11A of the container cover 1 shown in FIG. Moreover, since the edge part of the both sides of a two-layer rectangular sheet is airtightly joined to a strip shape, and it is made to ring-close in a cylinder shape, this junction part becomes the ring-closing junction band 31 of the container cover 1 shown in FIG. Further, when these are joined, the outer sheet 12 and the inner sheet 13 can be joined to form the divided joining band 32. The container cover 1 shown in FIG. 1 formed in this way includes an outer sheet 12 and an inner sheet 13 having the same size. Further, two sheets of non-breathable soft material having the same size are cut into a rectangular shape, and one opposing side is joined to each of the upper edge 11A and the lower edge 11B of the container cover 1 shown in FIG. And the other opposite side can be joined in a band-like manner and ring-closed in a cylindrical shape to form a ring-closing junction band 31.

  In particular, as shown in FIGS. 1 and 3, when air is injected from the air inlet / outlet means 15, the air is injected into the entire air chamber of the cylindrical wall portion 11, and the air flows between the outer sheet 12 and the inner sheet 13. The container cover 1 is expanded by being supplied. During this expansion, the expansion is limited by the portion of the ring-closing joint band 31 and the seven divided joint bands 32, and the other parts expand. Since the ring-closing joining band 31 and the seven divided joining bands 32 that limit the expansion are arranged in parallel to each other in the circumferential direction (the direction of the arrow B) at a substantially equal interval, a plurality of them are formed between them. The ventilation small chambers 61 (61a, 61b, 61c, 61d) respectively expand in the same state as a whole, and in each ventilation small chamber 61 (61a, 61b, 61c, 61d), the outer sheet 12 faces outward. Thus, the inner sheets 13 expand to the same extent toward the inner side. However, as shown in FIG. 2, when the baby bottle 2 is present inside the container cover 1, the container cover 1 can tightly fix the baby bottle 2 by preventing the inner sheet 13 from expanding inward. it can. Moreover, even if the outer shape of the baby bottle 2 has a concave portion or a convex portion in the height direction, the inner sheet 13 expands along these concave and convex shapes, so that close contact is maintained. The degree of expansion can be controlled by the interval at which the ring-closing junction band 31 and the seven split junction bands 32 are provided.

  In the embodiment of the container cover 1 shown in FIG. 1, the upper end portion 32A and the lower end portion 32B of each split joining band 32 do not reach the upper end edge 11A and the lower end edge 11B of the cylindrical wall portion 11, respectively. Any one of the upper end portion 32A and the lower end portion 32B of each divided joining band 32 reaches either the upper end edge 11A or the lower end edge 11B of the cylindrical wall portion 11, and air is generated at the end edge. May be blocked. Moreover, it is not necessary for each division | segmentation joining band 32 to join continuously from those upper edge 11A to the lower end part 32B, and it breaks by including a non-joining part in one or several places, and the distribution | circulation of air Can also be made possible. In this case, both the upper end portion 32A and the lower end portion 32B of each divided joining band 32 may reach the upper end edge 11A and the lower end edge 11B of the cylindrical wall portion 11. In each longitudinally divided joining band that is disconnected by including a non-joined portion at one or a plurality of locations, each vent chamber is arranged by arranging one or a plurality of non-joined portions at equivalent positions in the circumferential direction. It is preferable to adjust so that each is expanded in the same manner in the circumferential direction.

  Each divided joining band 32 is continuously or discontinuously, from one upper end region 11T (or upper end edge 11A) of the cylindrical wall portion 11 to the other lower end region 11S (or lower end edge 11B). ), But the ratio (L1 / Lt) of the total length (L1) of the joining band portion to the length (Lt) from the upper edge 11A to the lower edge 11B of the cylindrical wall portion 11 Is preferably 0.6 or more, more preferably 0.7 or more, and most preferably 0.8 or more. However, since it is necessary to ensure the ventilation of air, it is necessary to be less than 1.0, and preferably 0.04 or more. In addition, when the ratio (L1 / Lt) is set to 0.6 or more, the outer shape of the container cover 1 at the time of expansion can be kept substantially uniform as a whole.

  Although the number of the division | segmentation joining bands 32 with which the container cover 1 shown in FIG. 1 is provided is not particularly limited, the total number of one ring-closing joining band 31 and a plurality of divided joining bands 32 is preferably 4 to 20, more preferably 5 to 5. 16, most preferably 6-12. When the total number is less than 4, when air is injected, the uniformity of the outer shape is impaired, not only the appearance is impaired, but also the container cover is difficult to grasp. If the total number exceeds 20, the degree of expansion of each ventilation chamber is limited, so the type (outer shape) of containers to which one type of container cover can be applied is limited, and in some cases, adhesion may be impaired. .

  The container cover 1 shown in FIG. 1 is discontinuous (that is, disconnected in the circumferential direction (direction of arrow B) of the cylindrical wall portion 11 in the region below the upper end region 11T of the cylindrical wall portion 11. ) A folding joining band 35 (35a, 35b, 35c, 35d) is provided. The folding joining band 35 is also formed by joining the outer sheet 12 and the inner sheet 13 and is folded when the upper end region 11T of the cylindrical wall portion 11 is folded inside the inner space 14 of the cylindrical wall portion 11. Can be used as a line. FIG. 4 is a schematic perspective view showing a state in which the flat container cover 1 is folded using the folding joining band 35, and FIG. 5 shows a short baby bottle on the folded container cover. It is a typical perspective view showing the state where it was made to be in an inflated state after being inserted and closely attached. As described above, when the container cover 1 is folded by the folding joining band 35, the length (height) of the cylindrical wall portion 11 in the axial direction (the direction of the arrow A) is shortened. When the height is low, it can be folded and used. In addition, since air is injected into the air chamber in the upper end region 11T of the cylindrical wall portion 11 while being folded inward, the adhesion between the container cover and the container can be improved at that portion. .

  Note that, in the upper end region 11T of the cylindrical wall portion 11, a folding joining band 35 (35a, 35b, 35c, 35d) extending discontinuously (that is, broken) in the circumferential direction (the direction of arrow B). ) Is sufficient for adjusting the length of the container cover 1, but as shown in FIGS. 1 to 5, the axial direction of the cylindrical wall portion 11 is within the region of the upper end region 11 </ b> T. It is preferable that an auxiliary joint 63 extending in the direction of arrow A is provided. Since the expansion of the upper end region 11T can be limited by the presence of the auxiliary joint portion 63, the upper end region 11T is used without being folded inside the inner space 14 of the cylindrical wall portion 11 (that is, 1 to 3), it is possible to prevent the upper opening of the cylindrical wall portion 11 from spreading greatly outward and inward. When the upper end region 11T is used without being folded, in order to align the expansion mode of the upper end region 11T and the expansion mode of the intermediate portion of the cylindrical wall portion 11, As shown in FIGS. 1 to 5, it is preferable that the auxiliary joining portion 63 and each divided joining band 32 be continuous. Further, by changing the thickness and length of the auxiliary joint portion 63 in the upper end region 11T, the degree of expansion in the upper end region 11T is controlled, and the ventilation chamber 61 (61a, 61b, 61c, 61d). It can also be harmonized with the degree of expansion.

  As shown in FIG. 6, the container cover 1 </ b> A according to the present invention is not only provided with a folding joining band 35 in the region below the upper end region 11 </ b> T of the cylindrical wall portion 11, but also on the other side of the cylindrical wall portion 11. A folding joining band 36 can also be provided in the region above the lower end region 11S. When the two folding joint bands 35 and 36 are provided, both of them may be used by folding, one of them may be used by folding, or both may be used without folding. Depending on the, it can be provided in three different lengths. FIG. 6 shows the container cover 1A in a flat state before air is injected, and the same parts as those shown in FIGS. 1 to 5 are denoted by the same reference numerals (reference numbers), and the description thereof is omitted. . The number of folding joining bands is not limited to 1 or 2, but can be 3 or more, and the position where they are provided on the side surface of the cylindrical wall portion 11 (height in the direction of arrow A). Is not limited.

  As shown in FIG. 7, the container cover 1 </ b> B according to the present invention can include a pair of grip handle portions 41, 41 on the side portion of the cylindrical wall portion 11. As long as the grip handle portion is convenient for the user to grip with both hands when the container firmly fixed by the container cover 1B according to the present invention is used for drinking, the specific shape and the number of grip handle portions are not limited. There is no particular limitation. The grip handle portions 41, 41 can be either an air injection type or not an air injection type. In the case of the air injection type, it can be ventilated with the entire air chamber of the container cover 1 or may not be ventilated with the entire air chamber of the container cover 1 and may be provided with air inlet / outlet means separately. When the whole air chamber is ventilated, the air can be expanded simultaneously by injecting air from the air inlet / outlet means 15. One or three or more gripping handle portions may be provided. FIG. 7 shows the container cover 1B in a flat state before air is injected, and the same parts as those shown in FIGS. 1 to 5 are denoted by the same reference numerals (reference numbers), and the description thereof is omitted. The container cover 1B having a grip handle portion can also be used with a folding joint band, and in the case of using it together, the grip handle section is provided at a position where it can be folded simultaneously with the folding joint band. Alternatively, it may be provided at a position that does not obstruct the folding of the folding joint band. It should be noted that one or more suspension strap portions (not shown) may be provided in the upper end region of the cylindrical wall portion 11 instead of or in addition to the grip handle portions 41, 41. And / or in the lower end region.

  As shown in FIG. 8, the container cover 1 </ b> C according to the present invention may include a buffer protection bottom 45 provided in a ring shape on the inner side along the circumferential edge of the lower edge 11 </ b> B of the cylindrical wall 11. When the buffer protection bottom 45 is capable of air circulation with the central air chamber of the cylindrical wall portion 11 through the ventilation portion 4 provided in a part of the circumferential bottom portion formation joining band 43, 1 It is preferable that air can be injected and discharged from one air inlet / outlet means 15, but it is airtightly independent from the central air chamber to form a separate air chamber (buffer protection bottom air chamber), and from another air inlet / outlet means. Air can be injected and discharged. When the buffer protection bottom 45 is provided, when the container cover 1 is manufactured, the lower edge 11B of the container cover 1 is formed by folding the sheet, and the circumferential bottom forming joining band 43 is joined to the upper part thereof. The buffer protection bottom portion 45 can be provided in the lower region of the cylindrical wall portion 11. In the buffer protection bottom 45, the ventilation portion 4 is provided in the bottom forming joining band 43 so that air can be injected and discharged from the air inlet / outlet means 15 common to the central air chamber of the cylindrical wall portion 11. In addition, you may provide one common air in / out means in the buffer protection bottom part air chamber of the buffer protection bottom part 45. FIG. Moreover, the ventilation part 4 is not provided in the bottom part formation joining band 43, but it may be set as a sealed air chamber different from the central air chamber of the cylindrical wall part 11, and a dedicated air inlet / outlet means may be provided.

  Since the buffer protection bottom portion 45 shown in FIG. 8 does not have an auxiliary joint portion in the inside thereof, there is no obstacle that prevents expansion when air is injected, and it greatly expands outward and inward as shown in FIG. The degree of exposure of the bottom of the container inside the container cover 1C can be reduced. That is, when the buffer protection bottom is not provided, the bottom of the container may be exposed from the opening of the lower edge 11B of the cylindrical wall 11, and in this case, the container is wrapped in the container cover. If the cover is accidentally dropped together with the container, the exposed portion may directly collide with the floor or the like and may be damaged. However, by providing the buffer protection bottom 45, the opening of the lower edge 11B of the cylindrical wall portion 11 can be opened. Since it is also partially covered on the inside, even if it is accidentally dropped, the bottom of the container can be prevented from directly colliding with the floor surface and being damaged. Particularly in the case of a glass baby bottle, it is effective from the viewpoint of safety.
