Referring to fig. 1 to 3, a storage bottle 10 according to an embodiment of the present invention includes a cover structure 100 and a bottle body 200. The cap structure 100 is disposed on the bottle 200, and the cap structure 100 is connected to the bottle 200 for keeping the bottle 200 sealed.

Referring to fig. 1 to fig. 3, in one embodiment, the cover structure 100 includes a cap 110, a sealing plug 120, a sealing ring 130 and a connecting ring 140. The bottle body 200 is provided with an opening 210 and a containing cavity 220 which are communicated with each other. The receiving chamber 220 communicates with the outside through the opening 210, and the receiving chamber 220 is used to store medicines or high-value consumables.

One end of the sealing plug 120 is sealingly engaged with the opening 210 of the bottle body 200. Specifically, the sealing plug 120 makes full contact with the sidewall of the opening 210 to keep the receiving chamber 220 relatively sealed. The other end of the sealing plug 120 contacts the cap 110. The above-mentioned full contact means that there is no space or gap between the sealing plug 120 and the side wall of the opening 210. The sealing ring 130 is sleeved on the bottle body 200 and is fixed relative to the bottle body 200.

The connection ring 140 is disposed on the sealing plug 120, and two opposite sides of the connection ring 140 are detachably connected to the cap 110 and the sealing ring 130, respectively. A plurality of protrusions 141 are provided on a side of the attachment ring 140 adjacent the sealing plug 120 and a plurality of protrusions 141 are provided around the sealing plug 120 and in contact with the sealing plug 120.

In the cap structure 100, the sealing ring 130 is sleeved on the bottle body 200 and can be relatively fixed with the bottle body 200. The two sides of the connection ring 140 are respectively connected with the cap 110 and the sealing ring 130, i.e., the cap 110 and the connection ring 140 can be relatively fixed with the bottle body 200 through the sealing ring 130. And the cap 110 contacts the end of the sealing plug 120 away from the opening 210, the sealing plug 120 can be kept in sealing engagement with the opening 210 by the cap 110, so as to ensure the sealing performance of the storage bottle 10.

Opposite sides of the connection ring 140 are detachably connected to the cap 110 and the sealing ring 130, respectively, i.e., the cap 110 is connected to the sealing ring 130 only through the connection ring 140. When the storage bottle 10 needs to be opened, the cap 110 is not fixed relative to the bottle body 200 any more by separating the connection ring 140 from the sealing ring 130, that is, the cap 110 can be separated from the bottle body 200, so that the storage bottle 10 can be opened, and the operation method is simple.

Further, since the connection ring 140 is provided with a plurality of protrusions 141 contacting the sealing plug 120. The sealing plug 120 can be radially retained by the plurality of projections 141, which stabilizes its position. Furthermore, the contact positions of the protrusions 141 and the sealing plug 120 have friction, so that the sealing plug 120 can be radially limited by the protrusions 141.

It should be noted that, in the conventional art, a clamping portion (not shown, the same applies below) is provided on the cap 110 to be engaged with the sealing plug 120, and the sealing plug 120 is limited in the radial direction and the axial direction by the engagement of the clamping portion and the sealing plug 120. However, when the cap 110 is separated from the bottle body 200, the sealing plug 120 is also separated from the bottle body 200 along with the cap 110, i.e. when the cap 110 is separated from the bottle body 200, the bottle body 200 loses its sealing state, which may easily cause leakage of the storage bottle 10.

In this embodiment, the cap 110 is in simple contact with the sealing plug 120 only, and axially limits the same. While the sealing plug 120 is radially restrained by a plurality of projections 141. The position of the sealing plug 120 is not affected, or is less affected, when the cap 110 and the attachment ring 140 are separated from the housing. In this manner, opening of the storage bottle 10 can be facilitated and leakage of the storage bottle 10 during opening can be prevented.

In various embodiments, it can be understood that the connection ring 140 is sleeved on the sealing plug 120, and two opposite sides of the connection ring 140 are respectively connected to the cap 110 and the sealing ring 130, so that the sealing plug 120 is disposed in a space enclosed by the cap 110, the sealing ring 130 and the connection ring 140, and the spatial position of the sealing plug 120 can be defined by the three.

Referring to fig. 2, in one embodiment, one of the sealing ring 130 and the bottle body 200 is provided with a protrusion 131, and the other is provided with a slot 230 engaged with the protrusion 131. The sealing ring 130 and the bottle body 200 can be kept relatively fixed through the matching of the clamping groove 230 and the projection 131.

Referring to fig. 3 and 4, in one embodiment, the connection ring 140 includes a first side 142 and a second side 143 opposite to each other, and a third side 144 and a fourth side 145 opposite to each other.

The first side 142 includes a plurality of first connecting portions (not shown, the same applies below) surrounding the cap 110 and spaced apart from each other, and the plurality of first connecting portions are connected to the cap 110. The second side 143 includes a plurality of second connecting portions (not shown, the same applies below) spaced around the sealing ring 130, and the plurality of second connecting portions are connected to the sealing ring 130. In this way, the connection between the connection ring 140 and the cap 110 and the sealing ring 130 is broken by moving the connection ring 140 away from the sealing plug 120 to break the plurality of first and second connections. Thereby enabling the connection ring 140 and the cap 110 to be separated from the sealing ring 130 and the sealing plug 120 to lose the radial and axial restraint from the cap 110 and the connection ring 140.

With continued reference to fig. 3 and 4, in one embodiment, the connecting ring 140 is elongated around the outer circumference of the sealing plug 120. The plurality of protrusions 141 are provided on the fourth side 145. The third side 144 is provided with a radially outwardly extending handle 146, which handle 146 is provided at one of the end portions 147 of the attachment ring 140. In this manner, one of the ends 147 of the attachment ring 140 can be pulled by the handle 146 to move the end 147 away from the sealing plug 120. Thereby enabling the first connection portion connected between the cap 110 and the connection ring 140 and the second connection portion connected between the seal ring 130 and the connection ring 140 to be broken and damaged by force. Thereby separating the connection ring 140 and the cap 110 from the sealing ring 130, i.e., separating the connection ring 140 and the cap 110 from the bottle 200.

In some embodiments, the first side 142 is coupled to the cap 110 by a neck (not shown, the same applies below). The necks are annularly disposed between the first side 142 and the cap 110. The neck portion tapers in thickness in a direction along the axis of the attachment ring 140 from the attachment ring 140 toward the cap 110. The minimum neck thickness can be located on the neck intermediate the opposing first side 142 and the cap 110, or can be located on the neck in an area closer to the first side 142. Of course, the neck portion may be located at a region closer to the cap 110, and may be set according to actual requirements. The above thickness refers to a dimension of the neck portion in a radial direction of the connection ring 140. So configured, separation of the connection ring 140 from the cap 110 can be facilitated.

Similar to the connection between the first side 142 and the cap 110, the second side 143 and the sealing ring 130 may be connected by a neck as described above to facilitate separation of the connection ring 140 from the sealing ring 130, and will not be described again.

In one embodiment, one of the connection manner of the cap 110 and the first side 142, the connection manner of the sealing ring 130 and the second side 143, or both of them may adopt a separable connection manner such as clamping, etc. according to actual requirements, and are not limited herein.

In one embodiment, the cap 110, the connection ring 140, and the sealing ring 130 may be integrally formed of a high molecular polymer by injection molding. In particular, the plastic material can be integrally molded by injection molding of PP. Therefore, the sections of the torn sealing ring 130, the torn cap 110 and the torn connecting ring 140 are not too sharp, and potential safety hazards are avoided. Certainly, the cap 110, the connection ring 140 and the sealing ring 130 may be respectively formed by injection molding and connected together by corresponding process means, and may be configured according to an actual connection manner and a structural requirement, which is not limited herein.

In one embodiment, the protrusion 141 is an elastic body, and the protrusion 141 elastically abuts against the sealing plug 120. The protrusion 141 can be kept in contact with the sealing plug 120 by the elastic abutting force of the protrusion 141. For example, when the storage bottle 10 is shaken during transportation, there is a different tendency for movement between the sealing plug 120 and the protrusion 141. The protrusion 141 is elastically abutted to the sealing plug 120, so that relative movement between the sealing plug 120 and the protrusion 141 can be avoided, and the sealing performance of the storage bottle 10 is prevented from being influenced by displacement of the sealing plug 120 in the radial direction and the axial direction.

In one embodiment, the sealing plug 120 is an elastomer, or both the sealing plug 120 and the protrusion 141 are elastomers. The protrusion 141 is elastically abutted with the sealing plug 120, so that the limiting effect of the protrusion 141 on the sealing plug 120 is ensured, and the sealing performance of the storage bottle 10 is ensured.

Referring to fig. 5, in one embodiment, the cap 110 includes a plate 111. The connection ring 140 is connected to the radially outermost region of the plate body 111. It will be appreciated that in this embodiment, the cap 110 may not have a sidewall that encloses the sealing plug 120. Thus, on the one hand, when the cap 110 is separated from the bottle body 200, the connection relationship between the sidewall enclosing the sealing plug 120 and the sealing plug 120 can be prevented from affecting the relative position of the sealing plug 120. In other words, the cap 110 is prevented from being separated from the bottle body 200 together with the sealing stopper 120. On the other hand, the structure of the cap 110 can be simplified, and material can be saved.

Of course, in another embodiment, the cap 110 may further include a side fence (not shown, the same applies below) connected to the periphery of the plate 111. The side barriers are in contact with the sealing plug 120 at least in part.

Referring to fig. 2 in conjunction with fig. 5, in one embodiment, the plate 111 is provided with an abutment member on a side thereof adjacent to the sealing plug 120, and the abutment member axially abuts against the sealing plug 120. The sealing plug 120 can be restrained in the axial direction by the abutment member, and the sealing plug 120 is prevented from being separated from the sidewall of the opening 210.

Referring to fig. 5 and 6, specifically, the abutting member includes a first protrusion 112a protruding from the plate 111 toward the sealing plug 120, and the first protrusion 112a contacts the sealing plug 120. A second protrusion 121 protrudes from an end surface of the sealing plug 120 close to the cap 110 toward the plate 111, and the second protrusion 121 contacts the plate 111. The first protrusion 112a and the second protrusion 121 ensure that the sealing plug 120 and the plate body 111 are in contact with each other, and the contact area between the sealing plug 120 and the plate body 111 can be reduced. Thus, the sealing plug 120 and the plate body 111 can be prevented from being adhered to each other to form a whole due to the long-term close contact between the sealing plug 120 and the plate body 111.

It is understood that the storage bottle 10 may be provided with both the first protrusion 112a and the second protrusion 121. Alternatively, the storage bottle 10 may be alternatively provided with the first protrusion 112a or the second protrusion 121, which can also achieve the above-mentioned effects.

In certain embodiments, the abutment comprises an abutment. The abutting portion is annularly provided on the plate body 111. The abutment comprises an abutment surface 113 which is in contact with the sealing plug 120. The perpendicular distance of the abutment surface 113 from the central axis of the sealing plug 120 gradually decreases with reference to the direction from the sealing plug 120 to the plate body 111 along the central axis of the sealing plug 120. I.e. in the reference direction, the abutment surface 113 is tapered. In this way, the contact area between the plug 120 and the contact surface 113 can be relatively reduced. The central axis of the sealing plug 120 is seen in fig. 5 in dashed line K.

The maximum perpendicular distance between the abutment surface 113 and the central axis of the sealing plug 120 is greater than the radial dimension of the sealing plug 120 at the end close to the plate body 111. That is, the contact portion can be fitted to the outside of the plug 120 at the maximum size of the contact surface 113, and the plug 120 can be restrained both in the axial direction and in the radial direction. Furthermore, since the contact surface 113 is tapered in the reference direction, the contact area between the sealing plug 120 and the contact surface 113 is relatively reduced, and the frictional force of the sealing plug 120 sliding against the contact surface 113 is relatively reduced, thereby facilitating the separation of the sealing plug 120 from the contact portion.

The minimum value of the perpendicular distance of the abutment surface 113 from the central axis of the bore seal 120 is less than the radial dimension of the bore seal 120 at the end closer to the panel 111. In this way, the end surface of the sealing plug 120 can be prevented from being in full-face contact with the end surface of the plate body 111.

In one embodiment, the abutment may be provided on the plate 111 without interruption around the sealing plug 120. To fully abut the sealing plug 120.

Referring to fig. 5, the abutting portion includes a plurality of abutting blocks 112b annularly and alternately distributed on the plate 111. The contact blocks 112b are each provided with a contact surface 113. It will be appreciated that the abutment surface 113 in this embodiment is the same as the abutment surface 113 described in the above embodiments. It can also be understood that the abutting surface 113 of any abutting block 112b in this embodiment is disposed at an angle to the plate body 111, and the abutting surface 113 is inclined in a direction away from the axial direction of the sealing plug 120.

By providing a plurality of contact surfaces 113 spaced apart, material can be saved and the contact area between the contact surfaces 113 and the bore seal 120 can be reduced.

It should be noted that the abutting member may include the first convex portion 112a, the second convex portion 121, and the abutting portion at the same time, or the abutting member may alternatively include the first convex portion 112a, the second convex portion 121, and the abutting portion, or the abutting member may include any two of the first convex portion 112a, the second convex portion 121, and the abutting portion.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
